Description

  The present invention relates to a gaming machine, and more particularly to a technique that is effective when applied to a gaming machine such as a pachinko gaming machine or a slot machine in which a board case containing a control board is disposed inside the gaming machine.

  Conventionally, there has been a risk that a ROM or the like built in a board case inside the gaming machine (back of the base door) is illegally exchanged by a third party.

  Based on the view that it is more practical to discover the facts early and take subsequent measures in order to eliminate the possibility that the electronic circuit board for games will be tampered with due to unauthorized exchange etc. A gaming machine provided with a sealing member that seals the above has been devised (for example, Patent Document 1).

  The sealing head of the sealing member has an arrowhead shape, and a pair of locking pieces that can be elastically deformed inside each other is formed at the tip. The tip of the sealing head is inserted in a connection hole of the substrate case while being prevented from coming off.

  Therefore, if the sealing by the sealing member is to be released to open the substrate case, the sealing member is torn off, leaving a trace of opening the substrate case.

Thereby, the invention of Patent Document 1 can detect unauthorized opening of the substrate case. Therefore, it is possible to accurately determine whether or not the game electronic circuit board has been tampered with.
JP 2001-62114 A

  However, in the above prior art, the unauthorized opening of the substrate case can be detected, but when the substrate case itself is illegally replaced, the illegality to the substrate case cannot be detected.

  Accordingly, an object of the present invention is to provide a gaming machine capable of detecting fraud to a substrate case even when the substrate case itself is illegally replaced.

  In order to solve the above-mentioned problems, a gaming machine according to a first aspect of the present invention is mounted with a base frame (base frame 3b) constituting a part of the gaming machine main body, and supported by the base frame so as to be opened and closed. A board case (for example, main control) that holds a main control board on which a base door (base door 3a) and a main control circuit (main control circuit 200) that is arranged on the back side of the base door and controls the progress of the game is mounted Substrate case 100, etc.), a substrate case cover (substrate case cover 500) arranged to cover the substrate case, first detection means (first detection switch 600) for detecting the opening of the base door, and substrate case The second detection means (second detection switch 700) for detecting the opening of the cover and the main control board are arranged separately from each other and connected to the first detection means and the second detection means. A sub-control board on which a sub-control circuit (sub-control circuit 300) that executes predetermined control based on a control signal received from the main control circuit on the board is mounted, and a sub-control board that is a means for executing control related to a game Based on detection of opening of the base door by the first detection means, a flag indicating the opening of the base door (first detection flag in which a value (01) indicating the opening of the base door is stored) is stored in the storage means (work RAM 303). And when the opening of the substrate case cover is detected by the second detection means, it is determined whether or not the opening is illegal based on the detection results of the first detection means and the second detection means. Unauthorized opening determination means (sub CPU 301), and the unauthorized opening determination means stores in the storage means when the second detection means detects the opening of the substrate case cover. If the flag indicating that the door is open is not stored, it is determined that the opening is illegal. If the flag indicating that the base door is open is stored in the storage means, it is legal to open the substrate case cover. It is determined that it is.

  In this way, when the substrate case cover covering the substrate case is opened, whether or not the substrate case cover is illegally opened based on the detection results of the first detection means and the second detection means. Therefore, fraud to the substrate case can be accurately detected. In addition, this makes it possible to detect fraud on the substrate case even if the substrate case itself is illegally replaced.

Further, the unauthorized opening determination means of the present invention is configured such that when the flag indicating opening of the base door is not stored in the storage means, the opening of the substrate case cover is detected by the second detection means (that is, the base door opening state). When the substrate case cover is opened when no opening is detected), it is determined that the opening is illegal, while a flag indicating opening of the base door is stored (set) in the storage means. When the opening of the substrate case cover is detected by the second detecting means (that is, when the substrate case cover is opened when the opening of the base door is detected), it is determined that the opening is valid. To do. That is, when the substrate case cover is not opened based on a predetermined procedure, it is determined that the opening is illegal, while the substrate case cover is opened based on the predetermined procedure. In such a case, since it is determined that the opening is valid, the unauthorized opening can be detected more accurately. This also makes it possible to more reliably detect fraud on the substrate case even if the substrate case itself is illegally replaced.
In addition, since tampering by a third party is often performed on the main control board on which the main control circuit for controlling the progress of the game is mounted, it is illegally opened to the sub control board that is relatively unlikely to be tampered with. By providing the function of the determination means, it is possible to more accurately detect unauthorized opening of the substrate case cover or the like and to take more appropriate measures against unauthorized opening.

  According to a second aspect of the present invention, in addition to the configuration of the first aspect of the invention, the storage unit stores a determination result by the unauthorized opening determination unit.

  This makes it possible to store the number of times of unauthorized opening, the timing, etc., and collect more information on unauthorized opening. Therefore, it is possible to more appropriately take measures against unauthorized opening.

  According to a third aspect of the present invention, in addition to the configuration of the first or second aspect of the present invention, the present invention further comprises notification means (liquid crystal display device 21) for notifying the determination result by the unauthorized opening determination means. .

  As a result, when an unauthorized opening of a substrate case cover or the like is made, the fact is notified to the employee, etc., so that it is possible to appropriately deal with the unauthorized opening, due to unauthorized replacement of the substrate case, etc. The damage of tampering can be minimized.

Moreover, since the above-mentioned notification provides a deterrent against unauthorized opening, it leads to prevention of unauthorized opening.
According to a fourth aspect of the present invention, in addition to the configuration of the invention according to any one of the first to third aspects, the unauthorized opening determination unit determines that the opening of the substrate case cover is unauthorized. Is characterized in that the time when the unauthorized opening is started is stored in the storage means, and when the unauthorized opening of the substrate case cover is completed, the time when the unauthorized opening is completed is stored in the storage means. If the unauthorized opening determination means of this configuration determines that the opening of the substrate case cover is unauthorized, the time when the unauthorized opening is started is stored in the storage means, and the unauthorized opening of the substrate case cover is completed. In the case (when the opening of the substrate case cover is finished), the time when the unauthorized opening is finished is stored in the storage means.
According to this, since the unauthorized opening start time and the unauthorized opening end time of the substrate case cover are stored in the storage means (work RAM 303), the time when the unauthorized opening is performed and the unauthorized opening are thereby prevented. The time from the start to the end can be detected.

  According to the present invention, the following effects can be obtained.

  That is, according to the present invention, when the substrate case cover that covers the substrate case is opened, the substrate case cover is illegally opened based on the detection results of the first detection means and the second detection means. Therefore, it is possible to accurately detect fraud to the substrate case. In addition, this makes it possible to detect fraud on the substrate case even if the substrate case itself is illegally replaced.

  Hereinafter, the best mode for carrying out the present invention will be described more specifically with reference to the drawings. Here, in the accompanying drawings, the same reference numerals are given to the same members, and duplicate descriptions are omitted.

  As shown in FIGS. 1 and 2, in a pachinko gaming machine (game machine) 1, a base door 3a on which a game board 2 (FIG. 2) is mounted is fixed to an island facility via a hinge 3c (FIG. 5). The base door 3a is pivotally attached to the base frame 3b (that is, the base door 3a is supported with one end of the base door 3a being supported as a pivot, and is mounted to the base frame 3b so as to be openable and closable). A gaming machine main body 3 is constituted by the base door 3a and the base frame 3b. And the glass door 9 which covers the speakers 8a and 8b (FIG. 10), the liquid crystal display device (LCD) 21, and the game board 2 so as to be visible with respect to the base door 3a of the gaming machine body 3 and the upper plate portion. 4, a lower plate part 5, a cover 6 and a handle 7 are provided.

  As shown in FIG. 2, the game board 2 is surrounded by a rail 11 and has a game area 2a in which game balls can flow down. In the game area 2a, there are many obstacles (not shown) such as game nails and windmills, a general winning port 12, a passing gate 13, a big winning port 15, an out port 16, and start winning ports 14, 17 A gaming member composed of the electric accessory component member 18 is disposed.

  Here, the general winning opening 12 is a device in which a predetermined number of game balls are paid out when a game ball is won, and the passing gate 13 is a plurality of symbols displayed in the normal symbol display area when the game ball has passed. The start winning port 17 is a device for changing and stopping the special symbol displayed on the special symbol display area on the condition that the game ball has won, the special winning port 15 is a special winning port 15 The special symbol combination when the symbol display area is stopped becomes a specific symbol combination (hit display mode) set in advance to the big hit gaming state (the big hit gaming state means a state where a so-called big hit has occurred). When the transition is made, the door is opened and closed a predetermined number of times under a predetermined condition according to a predetermined setting (that is, the number of game balls passing through the specific area of the big prize opening 15 within a predetermined time is 1 Only when it is (so-called puncture does not occur), the special winning opening 15 is opened a predetermined number of times, and changes into a opened state where the game ball is easily received and a closed state where it is difficult to receive the game ball. The operation that changes to the closed state is called a round operation).

  The out port 16 is a device for collecting and collecting game balls that have not won any of the general winning port 12, the starting winning ports 14, 17 and the big winning port 15.

  The passing gate 13 detects a passing game ball. The game ball that has passed through the passing gate 13 can be stored as passing memory, and based on this passing memory information, the symbol variation display in the normal symbol display area is performed. Further, four normal symbol memory LEDs (not shown) for displaying the number of passage memories of the passage gate 13 are provided on the upper right side of the game area 2a. The number of stored game balls that have passed through the passage gate 13 can be displayed by the number of lighting of the normal symbol memory LEDs.

  In the normal symbol display area, for example, two normal symbols flash alternately, and when the two normal symbols stop flashing and “winning” is displayed, the electric accessory component The start winning opening 17 provided at 18 is switched to a state in which a game ball can be easily received for a predetermined time.

  Instead of the normal symbol display area, two normal symbol display LEDs may be provided at an arbitrary place on the game board 2, and "winning" may be displayed by blinking these LEDs. Further, the two normal symbol display LEDs can be constituted by, for example, a 7-segment display. In this case, numbers such as “0”, “1”, “2”,... “7”, “8”, “9”, etc. are displayed in a variable manner as normal symbols displayed on the 7-segment display. The case where the stop-displayed number becomes “3” or “7” is defined as “winning”.

  The start winning port 17 has a receiving port for receiving a game ball, and is an apparatus provided with an opening / closing mechanism that can be switched between a state where it is easy to receive a game ball and a state where it is difficult to receive a game ball. The start winning port 17 is in a state in which it is difficult to accept a game ball in a normal state, and when a predetermined condition is satisfied (for example, the normal symbol in the normal symbol display area stops at a symbol meaning “win”) In such a case, the game ball is opened for a predetermined time (for example, 0.3 seconds) and switched to a state in which the game ball can be easily received. Note that a predetermined number of game balls are paid out when a game ball wins in the receiving port.

  Also, the winning balls to the start winning ports 14 and 17 can be memorized, and based on this memorized memory, the special symbols are displayed in a variable manner in the special symbol display area. In the center of the game area 2a, four special symbol storage LEDs (not shown) for displaying the number of winning prizes stored in the start winning openings 14, 17 are provided. Based on the number of lighting of the special symbol memory LED, the number of winning prizes stored in the start winning holes 14, 17 can be displayed.

  Further, the special symbols displayed in the special symbol display area are composed of, for example, three columns of numbers such as “0”, “1”, “2”... “9”, and the game ball wins the start winning opening 17. As a result, these numbers are displayed in a variable manner. Note that the fluctuation display of these numbers is completed, and the fluctuation display results (that is, combinations of numbers that are stopped and displayed, also called stop symbols) are “0”, “0”, “0”, and “7”. A combination of special symbols when all three symbols have the same number, such as “7”, “7” ”, etc., is referred to as a jackpot display mode (big hit symbol). This jackpot display mode is a display mode for allowing the player to recognize that the gaming state has shifted to a jackpot gaming state that is advantageous to the player as compared to the normal gaming state (ie, it has become a “hit”). is there. Note that the variable display result other than the jackpot display mode is referred to as a non-hit display mode (offset symbol).

  The big hit gaming state is a gaming state in which, for example, a big prize opening SOL72S, which will be described later, makes it easier to win more game balls than the normal gaming state by opening and closing the door of the big prize opening 15 a predetermined number of times. It is.

  Note that the above jackpot display mode for allowing the player to recognize that the game has shifted to the jackpot gaming state is a special display mode (probability variation jackpot symbol) that is a display mode that indicates probability variation jackpots, and a display mode that indicates a normal jackpot. It is divided into certain non-special display modes (usually big hit symbols).

  The special display mode means a case where three predetermined numbers such as “7” and “3” are arranged, while the non-special display mode is a case where three numbers and designs other than the special display mode are arranged. Say.

  When the special symbol variation display result becomes a special display mode (that is, when the probability variation jackpot), the probability that the special symbol variation display result in the special symbol display area becomes the jackpot display mode after the jackpot gaming state is high. Transition to a special gaming state (probability variation state). On the other hand, when the display mode of the special symbol becomes a non-special display mode (that is, when a normal big hit is made), the game state is shifted to the normal gaming state after the big hit gaming state ends.

  In the present embodiment, the above-mentioned winning memory number and passing memory number are displayed on the normal symbol memory LED and the special symbol memory LED, respectively. However, the present invention is not limited to this, and other display methods may be used. May be displayed. For example, it may be displayed in the display area 21a.

A). On the other hand, when the fixing of the fixing portion 502 is released and the substrate case cover 500 is opened from the open / close end side, the contact portion 503 is separated from the second detection switch 700.

  Next, the first detection switch 600 and the second detection switch 700 will be described with reference to FIGS. 7, 8, and 9. Since the first detection switch 600 and the second detection switch 700 are similar in structure and function, only one first detection switch 600 will be described here.

  As shown in FIGS. 7 and 8, the first detection switch 600 includes a rectangular main body portion 610 and a switch portion 620 that is biased by a spring force and protrudes from the main body portion 610.

  As described above, the switch portion 620 protrudes by being biased by the spring force. When the switch portion 620 comes into contact with the outer frame portion 3d (that is, when the base door 3a is closed), the switch portion 620 is shown in FIG. Thus, the body 610 is depressed against the spring force.

  And when this switch part 620 leaves | separates from the outer-frame part 3d (that is, when the base door 3a is open | released from the opening-and-closing end side), as shown in FIG.9 (b), a spring force will act and will protrude again. It is like that.

  An electric circuit is provided inside the main body 610. When the switch 620 is in a protruding state, it is energized to detect this. As a result, the opening of the base door 3a can be detected. Note that this energization is released when the switch 620 is depressed.

  Here, the first detection switch 600 is electrically connected via wiring to a sub-control circuit 300 (described later) mounted on a sub-control board (not shown). When the opening is detected, a signal indicating that the base door 3a is opened (hereinafter referred to as “base door opening detection signal”) is mounted on the sub-control board until the energization is released. It can continue to be sent to the circuit 300.

  Note that the second detection switch 700 has the same configuration as the first detection switch 600. For example, when the substrate case cover 500 is opened and the switch portion (not shown) of the second detection switch 700 is separated from the contact portion 503 of the substrate case cover 500, the current is detected and this is detected. The signal indicating that the substrate case cover 500 is opened (hereinafter referred to as “substrate case cover open detection signal”) is continuously sent to the sub-control circuit 300 until the above is solved.

  As described above, electronic components, a board case, and the like are mounted on the back surface of the base door 3a.

  For example, when the game ball is won at the start winning ports 14 and 17, the jackpot gaming state determination means executes a jackpot determination process based on the random number value for jackpot determination extracted by random lottery, and the determination process results in a big hit. If it is determined that the game state is to be changed to the big hit game state (the big hit game state is set).

  Here, when it is determined by the jackpot gaming state determination means to shift to the jackpot gaming state, after the end of the special symbol variation display by the identification symbol variation display means described later, that is, the jackpot display mode ( After the jackpot symbol) is displayed, the gaming state transition means shifts the gaming state to the jackpot gaming state.

  As described above, there are two types of jackpots, the normal jackpot and the probability variation jackpot. If the probability variation jackpot, after the jackpot gaming state ends, the gaming state is changed to the next jackpot game by the gaming state transition means. Transition to a special gaming state with a high probability of becoming a state.

  Further, the identification symbol variation display control means generates and sets a variation display pattern command for causing the special symbol display area to perform variation display of the special symbol, and is based on the jackpot determination result of the jackpot gaming state determination means. Thus, the variation display pattern for executing the variation display of the special symbol is determined.

  Specifically, the identification symbol variation display means is a variation display pattern command for instructing a variation display pattern for executing the variation display of the special symbol and the display of the production information based on the result of the jackpot determination of the jackpot gaming state determination means. Then, a command for designating the stop display of the variable display is generated and set.

  This variable display pattern includes a special symbol display pattern and an effect information display pattern. Therefore, the variable display pattern command includes data designating a special symbol display pattern and data designating an effect information display pattern.

  The special symbol display pattern is a variation display pattern of a special symbol that is variably displayed in the special symbol display area. The special symbol display pattern also includes display time information indicating the variable display time of each of the three special symbols (for example, “left”, “middle”, and “right”). Therefore, the special symbol display pattern includes a variable display pattern and time information.

  The effect information display pattern is a pattern related to display of effect information such as a character. Therefore, an effect information display pattern corresponding to the number of characters is prepared, and an effect information display pattern of effect information (effect information image) is designated (instructed) to be actually displayed among these effect information display patterns. The Rukoto.

  When the gaming state is shifted to the big hit gaming state, the winning prize opening SOL control means controls a special winning opening SOL72S described later so as to open and close the door of the big winning opening 15 (open the big winning opening).

The voice control circuit 306 and the lamp control circuit 307 are controlled.

  Further, when the sub CPU 301 serving as the unauthorized opening determination means receives a detection signal (such as a base door opening detection signal or a substrate case cover opening detection signal) from the first detection switch 600 or the second detection switch 700, It is determined whether or not the case cover 500 is illegally opened.

  In the present embodiment, the sub CPU 301 receives the substrate case cover detection signal when the substrate case cover 500 is opened while the base door 3a is opened (that is, the base case cover detection signal is received when the base door detection signal is received). Only), it is determined that the opening is a legitimate opening.

  On the other hand, when the substrate case cover 500 is opened while the base door 3a is closed (that is, when the substrate case cover opening detection signal is received in a state where the base door opening detection signal is not received), the opening is performed. Is determined to be unauthorized.

  The sub CPU 301 that has determined that the substrate case cover 500 has been illegally opened generates and sets an unauthorized opening notification command for notifying the determination result.

  The unauthorized release notification command includes the time when the unauthorized release is started.

  In the program ROM 302, the sub CPU 301 processes a control program (control data) for controlling the image control circuit 305 based on various commands output from the main control circuit 200 and an unauthorized opening notification command, and a sound control circuit 306. A control program for controlling, a control program for controlling processing of the lamp control circuit 307, and the like are stored.

  When the sub CPU 301 receives the variable display pattern command from the main control circuit 200, the sub CPU 301 sets control data corresponding to the received command.

  Further, the sub CPU 301 changes data for instructing the image control circuit 305 with time so as to display special symbols and effect images in accordance with the effect patterns included in the set control data.

  The image control circuit 305 executes an instruction of the sub CPU 301 that is transmitted every predetermined time, so that, for example, a special symbol or effect image corresponding to the variable display pattern is displayed in the display area 21a.

  In addition, even when the sub CPU 301 generates an unauthorized release notification command, the sub CPU 301 sets control data corresponding to the unauthorized release notification command, similarly to the case where the variable display pattern command is received. As a result, the determination result by the sub CPU 301 as the unauthorized release determination means and the time when the unauthorized release is started are displayed in the information display area of the display area 21a (see, for example, FIG. 15).

  FIG. 15 is an explanatory diagram illustrating an example of a state in which the determination result by the unauthorized opening determination unit is displayed in the display area of the liquid crystal display device.

A second detection flag indicating that, an unauthorized release flag, and the like.

  Here, the substrate case cover unauthorized opening number counter is set to 0 in the initial state, and is updated every time the substrate case cover 500 is opened illegally. The counter is set so as not to be reset by power-off of the gaming machine 1 or an initialization process in step S210 described later.

  It should be noted that the value of the substrate case cover unauthorized opening number counter may be displayed in the information display area of the display area 21a at a predetermined timing, or may be displayed by the operation of the administrator of the gaming machine 1. It may be.

  In addition, by restricting access such as a password, a third party may not be able to confirm the value of the counter for unauthorized opening of the substrate case cover. As a result, only the true manager of the gaming machine 1 can collect detailed information (such as the number and timing of unauthorized opening) of unauthorized opening of the substrate case cover.

  The first detection flag is a flag indicating whether or not the base door 3a is in an opened state. When the base door 3a is closed, a value (00) indicating that the base door is closed is set. Yes.

  When the base door 3a is opened, a value (01) indicating that the base door is opened is set in the first detection flag.

  The second detection flag is a flag indicating whether or not the substrate case cover 500 is in an opened state. When the substrate case cover is closed, a value (00) indicating that the substrate case cover is closed is set. Yes.

  When the substrate case cover 500 is opened, a value (01) indicating that the substrate case cover is opened is set in the first detection flag.

  The unauthorized opening flag is a flag that indicates whether or not the unauthorized opening of the substrate case cover 500 has occurred. When the unauthorized opening has not occurred, a value (00) indicating normality is set. On the other hand, in the state where the unauthorized release has occurred, a value (99) indicating the unauthorized release is set.

  As described above, the work RAM 303 includes the unauthorized opening time storage area, the substrate case cover unauthorized opening number counter, the first detection flag indicating the open / closed state of the base door 3a, the second detection flag indicating the opened / closed state of the substrate case cover 500, By providing an opening flag or the like, it plays a role as a storage unit that stores the determination result by the unauthorized opening determination unit.

  In response to an instruction from the sub CPU 301 (an instruction based on control data set in a predetermined work area of the work RAM 303 in response to a command received from the main control circuit 200), the image control circuit 305 displays in the display area 21a. This is for executing display such as a special symbol variation display. The image data ROM 305b for storing various image data and the corresponding image data are extracted from the image data ROM 305b according to the control from the sub CPU 301, and the extracted image is displayed. A VDP (Video Display Processor) 305a that generates data for executing a special symbol variation display or a presentation image display based on the data, and a D / D that converts the display image data generated by the VDP 305a into an analog signal. A conversion circuit (D / A converter) 305d It comprises.

Here, each image data includes a plurality of pixel data (data in dot units) necessary to display each image data in the display area 21a.

  Here, a VRAM 305c having two buffer areas is connected to the VDP 305a. The VDP 305a performs the following processing when generating data for executing display in the display area 21a based on an instruction from the sub CPU 301 transmitted every predetermined time (for example, 1/30 second). The VDP 305a reads predetermined image data from the image data ROM 305b, develops it to the VRAM 305c, and reads the decompressed image data from the VRAM 305c. Specifically, the VDP 305a performs expansion processing on one buffer area provided in the VRAM 305c, and reads image data that has already been expanded from the other buffer area. Next, the VDP 305 a switches between a buffer area to be expanded and a buffer area to be read based on an instruction from the sub CPU 301. The VDP 305a displays the read image data on the display area 21a via the D / A conversion circuit 305d.

  Speakers 8 a and 8 b are connected to the audio control circuit 306. The sound control circuit 306 generates a sound signal based on the control of the sub CPU 301. The speakers 8a and 8b generate sound based on the input sound signal.

  A lamp / LED 39 a is connected to the lamp control circuit 307. The lamp control circuit 307 generates a signal based on the control of the sub CPU 301. The lamp / LED 39a performs lighting display of lamps and LEDs (for example, a normal symbol memory LED, a special symbol memory LED, etc.) provided in various places of the gaming machine 1 based on this input signal.

  Here, the speakers 8a and 8b, the lamp / LED 39a, and the above-described liquid crystal display device 21 serve as rendering means that produces an effect based on the control data set by the sub CPU 301.

  Each process in the pachinko gaming machine 1 is controlled by the main control circuit 200 and the sub control circuit 300. The main control circuit 200 processes all or part of the processes controlled by the sub control circuit 300. Alternatively, the sub control circuit 300 may process all or part of the processing controlled by the main control circuit 200.

If the value (99) indicating unauthorized release is set in the unauthorized release flag, the sub CPU 301 proceeds to the process of step S230-8, while the value (99) indicating unauthorized release in the unauthorized release flag. If is not set, the process proceeds to step S230-2.

  In step S230-2, the sub CPU 301 confirms whether or not the value (01) indicating the base door opening is set in the first detection flag. Then, when the value (01) indicating the base door opening is not set in the first detection flag, the sub CPU 301 proceeds to the process of step S230-3, while indicating the base door opening in the first detection flag. If the value (01) is set, the unauthorized opening determination process is terminated.

  In step S230-3, the sub CPU 301 confirms whether or not a value (01) indicating that the substrate case cover is open is set in the second detection flag. Then, when the value (01) indicating that the substrate case cover is opened is set in the second detection flag, the sub CPU 301 proceeds to the process of step S230-4, and on the other hand, the substrate case cover is opened in the second detection flag. In the case where the value (01) indicating is not set, the unauthorized release determination process is terminated.

  In step S230-4, the sub CPU 301 serving as the unauthorized opening determination unit sets a value (99) indicating unauthorized opening in the unauthorized opening flag. That is, when the opening of the substrate case is detected by the second detection unit, the sub CPU 301 determines whether the opening is illegal based on the detection results of the first detection unit and the second detection unit. judge.

  In step S230-5, the sub CPU 301 performs unauthorized release start time storage processing.

  Specifically, the time when the value (99) indicating unauthorized release is set in the unauthorized release flag in step S230-4 is stored in the unauthorized release time storage area of the work RAM 303.

  In step S230-6, the sub CPU 301 adds “1” to the substrate case cover unauthorized opening number counter.

  In step S230-7, the sub CPU 301 generates an unauthorized release notification command including the time when the unauthorized release is started (that is, the time when the value (99) indicating unauthorized release is set in step S230-4). While being stored in the RAM 303, predetermined processing is executed based on the unauthorized release notification command.

  That is, the sub CPU 301 sets control data corresponding to the unauthorized release notification command in the work area of the work RAM 303.

  In step S230-8, the sub CPU 301 confirms whether or not the value (01) indicating that the substrate case cover is open is set in the second detection flag. Then, when the value (01) indicating that the substrate case cover is opened is not set in the second detection flag, the sub CPU 301 proceeds to the process of step S230-8, while the substrate case cover is opened in the second detection flag. Is set (01), the unauthorized release determination process is terminated.

  In step S230-9, the sub CPU 301 serving as the unauthorized release determination unit sets a value (00) indicating normality to the unauthorized release flag. That is, the sub CPU 301 makes a determination that the unauthorized release has ended.

  In step S230-10, the sub CPU 301 performs an unauthorized opening end time storage process.

  Specifically, the time when the value (00) indicating normality is set in the unauthorized release flag is stored in the unauthorized release time storage area of the work RAM 303.

  Again, a description will be given with reference to FIG. In step 250, the sub CPU 301 confirms the control data set in step S202 (FIG. 11), step S230-7 (FIG. 14), and the like, and the control data is a control program for controlling the processing of the image control circuit 305. If there is, the image display control process is executed based on the control data.

  For example, when the control data corresponding to the variation display pattern command is set in step S202 (FIG. 11), the sub CPU 301 performs variation display of the special symbol according to the variation display pattern included in the set control data. Data for instructing the VDP 305a is changed over time. By executing the above instruction transmitted by the VDP 305a every predetermined time, the special symbol corresponding to the variable display pattern command is displayed in the special symbol display area of the liquid crystal display device 21 during the variable display time. When the variable display time is over, the special symbol is stopped after displaying the symbol indicated by the stop symbol command.

  Further, the sub CPU 301 changes the data for instructing the VDP 305a with time so as to display the effect information image according to the effect pattern included in the set control data. By executing the above instruction transmitted by the VDP 305a every predetermined time, an effect information image corresponding to the variable display pattern command is displayed in the display area 21a.

  On the other hand, when the control data corresponding to the unauthorized release notification command is set in step S230-7 (FIG. 14), the sub CPU 301 changes the data for instructing the VDP 305a over time according to the set control data. By executing the above instruction transmitted by the VDP 305a every predetermined time, information included in the unauthorized release notification command (that is, the time when unauthorized release is started) and unauthorized release occur in the information display area of the display area 21a. Display of information or the like for notifying the effect is performed (see FIG. 15).

  In step S260, the sub CPU 301 executes voice control processing.

  Specifically, in the voice control process, the sub CPU 301 performs control when the control data set in step S202 (FIG. 11), step S230-7 (FIG. 14), or the like is data corresponding to voice control. Data is sent to the voice control circuit 306. The voice control circuit 306 causes the speakers 8a and 8b to output, for example, a sound signal for notifying the player of a predetermined gaming state based on the control data.

  In step S270, the sub CPU 301 executes a lamp / LED lighting control process.

  Regarding the lamp / LED lighting control processing, the sub CPU 301 sets the control data set in step S202 (FIG. 11), step S230-7 (FIG. 14), etc., as data corresponding to lamp or LED lighting control. If so, the control data is sent to the lamp control circuit 307. Based on the control data, the lamp control circuit 307 causes the lamp / LED 39a to turn on / off in accordance with, for example, a predetermined lighting / extinguishing pattern.

  In this main process, the processes from step S220 to step S270 described above are repeated.

  As described above, in the present embodiment, since the work RAM 303 serving as the storage means stores the value of the substrate case cover unauthorized opening number counter, the unauthorized opening start time, the unauthorized opening end time, and the like, It is possible to detect the number of times of opening, the time of unauthorized opening, the time from the start of unauthorized opening to the end, and the like.

  Further, in the present embodiment, the sub CPU 301 as the unauthorized opening determination means determines that the opening is an unauthorized opening when the substrate case cover 500 is opened while the base door 3a is closed. However, the present invention is not limited to this, and it may be determined that unauthorized opening occurs when other conditions are satisfied. For example, when the substrate case cover 500 is opened while the base door 3a is opened, the sub CPU 301 may determine that the opening is an unauthorized opening.

  In the present embodiment, when unauthorized opening of the substrate case cover 500 is performed, the determination result in the unauthorized opening determination means is displayed in the information display area of the display area 21a. Lamps and LEDs provided in various places of the gaming machine may be lit and displayed, or a sound for notifying that unauthorized opening has been made may be generated from the speakers 8a and 8b.

  Further, in the present embodiment, the board case cover 500 is provided with the bearing portions 501a and 501b, and the shaft portions 30a and 30b are provided on the back surface side of the base door 3a. Can be considered. For example, the substrate case cover 500 may include shaft portions 30a and 30b, and bearing portions 501a and 501b on the back side of the base door 3a.

  Further, in the present embodiment, the substrate case cover 500 is pivotally supported and attached to the shaft portions 30a and 30b on the back side of the base door 3a. It may be done.

When the covering substrate case cover 500 is opened, the substrate case cover is based on detection results of the first detection switch (first detection means) 600 and the second detection switch (second detection means) 700. Since it is determined whether or not the opening of 500 is unauthorized, it is possible to accurately detect the unauthorizedness to the substrate case. In addition, this makes it possible to detect fraud on the substrate case even if the substrate case itself is illegally replaced.

  Further, according to the present embodiment, the sub CPU 301 serving as the unauthorized opening determination unit performs the second detection switch in a state where the first detection switch (first detection unit) 600 does not detect the opening of the base door 3a. (Second detection means) When the opening of the substrate case cover 500 is detected by the 700, it is determined that the opening is illegal. That is, when the opening of the substrate case cover 500 is not performed based on a predetermined procedure, it is determined that the opening is unauthorized, so that the unauthorized opening can be detected more accurately. . This also makes it possible to more reliably detect fraud on the substrate case even if the substrate case itself is illegally replaced.

  Furthermore, according to the present embodiment, since the work RAM (storage means) 303 for storing the determination result by the unauthorized release determination means is provided, it is possible to store the number of times of unauthorized release, the timing, and the like. It is possible to collect more information on unauthorized opening. Therefore, it is possible to more appropriately take measures against unauthorized opening.

  Further, since the alteration by a third party is often performed on the main control board on which the main control circuit 200 for controlling the progress of the game is mounted, the third embodiment is relatively altered. By providing functions such as unauthorized opening determination means and storage means on the low-control sub-control board, it is possible to more accurately detect unauthorized opening of board case covers, etc., and to take more appropriate measures against unauthorized opening. Can be taken.

  In addition, according to the present embodiment, since the liquid crystal display device (notification unit) 21 that notifies the determination result by the unauthorized opening determination unit is provided, when the substrate case cover or the like is opened illegally, Since the employee is informed of this fact, it is possible to appropriately deal with the unauthorized opening and to prevent the damage caused by the unauthorized replacement of the substrate case or the like.

  Moreover, since the above-mentioned notification provides a deterrent against unauthorized opening, it leads to prevention of unauthorized opening.
