By sending the temporarily stored data to the LCD panel interface circuit 1100, the LCD panel 1120 performs various image displays including a change in the variable display speed in detail.

  FIG. 5 is a timing chart showing command transmission / reception timing. As described above, the command consists of a 1-byte length mode (MODE) and a 1-byte length event (EVENT). In this example, the main control unit 200 generates a strobe signal generated by itself when the command changes. Mode (MODE) information is transmitted in response to the first rise of (DUSTB), and event (EVENT) information is transmitted in response to the second rise of the strobe signal (DUSTB). In response to this, the CPU 1020 of the special symbol display device generates an interrupt when a strobe signal (DUSTB) is transmitted, receives a command by this interrupt processing, and stores it in the RAM 1090.

  Next, normal control operations performed by the main control unit 200 and the CPU 1020 of the special symbol display device 100 will be described with reference to FIG. 10 (general flowchart of game control) and FIG. 11, and then, characteristic operations of the present invention will be described. To facilitate the understanding of the present invention. The series of processing shown in FIG. 10 is performed by the main control unit 200 executing a game control program (not shown) stored in the ROM 201. More specifically, a reset signal supplied from the reset circuit 213 every predetermined time (for example, 4 msec) is used as a trigger to start from the first step, and this series of processes is repeatedly executed.

  First, when the power supply circuit 212 is activated by a power switch (not shown), the main control unit 200 is activated, and it is determined whether or not the first processing has been executed since the power was turned on (step S110). . In the case of the first process after the power is turned on (Yes), the process proceeds to Step S200. In other cases (No), the process proceeds to Step S120.

  In step S200, a storage area clearing process is executed as an initialization process of the RAM 203. Next, in step S210, data for performing an initial control process is set in a predetermined area of the RAM 203. On the other hand, in step S120, the count value of various random number generation loop counters (not shown) for determining big hits, small hits, etc. formed in the RAM 203 is incremented, and in step S130, various timers used for game machine control. Update the timer value.

  In step S140, an input port process for reading and storing the detection signals output from the special symbol start switch 304, the normal symbol operation switch 306, and the special prize opening switch 308 into a register in the terminal (not shown) via the input port 210 is executed. Next, the process proceeds to step S150, and a switch check process for grasping the data read and stored in the port input process is executed.

  In step S160, the switches 304, 306, 308, etc. are checked for disconnection or short circuit. If these faults have occurred (Yes), the process proceeds to step S220. (No) The process proceeds to step S180 (step S170).

  In step S180, data necessary for display control of the normal symbol display device 108 is stored in a predetermined area of the RAM 203, and a command necessary for display control of the special symbol display device 100 (described above with reference to FIGS. 6 to 9). Command) is stored in a predetermined area of the RAM 203, and the timer values of the various timers are reduced (step S190). In step S180, the main control unit 200 determines a necessary mode and event command in accordance with the game control with reference to the command data table area 202, and sets digital information indicating the determined mode and event in the RAM 203. Store in the area.

  In step S195, in order to control the opening / closing member 120 of the special winning opening 106 and the opening / closing member 120 of the special symbol starting opening 104 in a predetermined pattern, the start opening operating solenoid 300 and the special winning opening operating solenoid 302 are driven and controlled. In S220, a prize ball setting process for outputting control information for causing a prize ball payout device (not shown) to perform a payout operation is executed. In steps S230, 240, and 250, various game machine management devices (not shown) External information processing for outputting game data, indicator light control processing for storing in the predetermined area of the RAM 203 a command for controlling lighting of the lamp display devices 110 and 112 corresponding to the gaming state, and setting the sound effect generating device 116 to the gaming state A command for controlling the sound effect generation correspondingly is stored in a predetermined area of the RAM 203. The sound effect processing to be executed.

  In step S260, the data stored in the RAM 203 in each process is output to the corresponding device via the output port 215 (port output processing), and the device that receives this performs a control operation based on this. Then, a strobe signal is first output to the special symbol display device 100, and the mode and event data stored in the RAM 203 in step S180 are transmitted as shown in FIG. Thus, for example, the commands shown in FIGS. 6 to 9 are transmitted to the special symbol display device 100 from the main control unit 200 and received.

  In step S270, a reset waiting process is executed until a reset signal is input from the reset circuit 213. If a reset signal is input, the process proceeds to step S110 to continue the gaming machine control. The reset waiting process includes updating the various random number generation counters described above.

  Next, the operation of the CPU 1020 of the special symbol display device 100 that has received the command will be described with reference to FIG. First, in step S1100, the CPU 1020 sets its own stack pointer, initializes the RAM 1090, initializes itself such as register clear, and the like, and determines in step S1102 whether a new command has been input. If it is determined that a new command for display control has been input (Yes), the process proceeds to step S1104; otherwise (No), the process proceeds to step S1110.

  In step S1104, in the interrupt processing described with reference to FIG. 5, the command received by the data receiving circuit 1140 is copied to the RAM 1090, and it is checked whether or not the command is normal. Next, the CPU 1020 determines the start address of a processing table (not shown) in order to obtain a necessary command for performing fine display control independently of the main control unit 200, and then in step S1108, the image In order to output to the processing LSI 1060, data in a necessary area of the RAM 1090 is updated.

  In step S1110, based on the symbol control data set in the RAM 1090, scroll data to be output to the image processing LSI 1060 is obtained and set in the RAM 1090, the symbol display position is set, and then in step S1112 Data required for the symbol speed control is acquired from a speed table (not shown) built in the program ROM 1040 and set in the RAM 1090. Next, in step S1114, the symbol offset value is updated based on the velocity data, Prepare to change symbols at the set speed.

  In step S1116, animation data is acquired from an animation processing table (not shown) in which animation processing data set in the RAM 1090 is stored, preparation for displaying a background image is performed, and the VDP output in the RAM 1090 is output. It is set in the buffer, and it is determined whether or not the output permission flag is “1” (step S1118).

  If the output permission flag is not “1” (No), the process returns to Step S1102 and repeats the series of processes. On the other hand, if the output permission flag is “1” (Yes), the VDP is determined in Step S1120. Data set in the output buffer is output to the image processing LSI 1060. In response to this, the image processing LSI 1060 acquires the data in the character ROM 1180 and develops the image. The image developed data is temporarily stored in the video RAM 1080 and then sent to the LCD panel interface circuit 1100 to be sent to the LCD panel. The image display by 1120 is performed. In this manner, the display of the symbol variation display at the set speed is performed at the set display position in the special symbol display device 100.

  FIGS. 13 and 14 are an example of a transmission timing of a command transmitted from the main control unit 200 to the special symbol display device 100, and an explanatory diagram of the transmission command, respectively. As can be seen from these drawings, the main control unit 200 first starts the symbol variation and changes the variation pattern when a predetermined condition such as a game ball winning in the special symbol starting port 104 is satisfied. A command for designating is sent (1), a command for designating a left stop symbol is sent after a lapse of T1 (2), and a command for designating a middle stop design is sent after a lapse of T2 (3) A command for designating a right stop symbol is transmitted after the elapse of T3 (4), and a command (5) for stopping all symbols is transmitted after a lapse of T time from the start of fluctuation. The CPU 1020 of the special symbol display device 100 that has received the first command (1) performs a series of variable display control by performing fine display control such as change in the variable speed, and the third frame. After the variable display control is terminated with the reception of the command (5), the special symbol lottery result is displayed by performing the stop display at the stop symbol designated by the received second command (2, 3, 4). To do.

  FIG. 15 is a configuration diagram of the characteristic part of the embodiment of the present invention. As shown in FIG. 2, the main control unit 200 receives power supply from the power supply circuit 212, but the power-on switch 214 provided between the power supply circuit 212 and the main control unit 200 is turned on. On the other hand, power is supplied from the power supply circuit 212 to the main control unit 200, but such power supply is not performed when the power-on switch 214 is not turned on.

  The main control unit 200 is connected to a ROM 201 in which an operation program is recorded and a RAM 203 used as a work area so that the operation can be controlled. As shown in FIG. The A area 204 and the B area 205 are divided into two parts. Buttons A320 and B321, which are dedicated buttons for each divided area for instructing clearing of each of the A area A204 and the B area 205, are connected to the main control unit 200, and the main control unit 200 is one of the buttons. This can be detected by pressing the button.

  In this embodiment, two buttons are individually provided for the A area 204 and the B area 205. However, the clearing of different divided areas is instructed according to the number of times one button is pressed. For example, it may be detected that the clearing of the A area 204 is instructed by one pressing operation, and that the clearing of the B area 205 is instructed by two pressing operations. good.

  Further, the main control unit 200 includes a display unit 311 that is lit so that it can be seen when the A area 204 is cleared, and an LED 312 that is lit so that it can be seen when the B area 205 is cleared. 310 is controllably connected. In the present embodiment, when the button A320 or the button B321 is pressed while operating the power-on switch 214, the main control is performed so as to detect that the clearing of the divided area corresponding to the pressed button is instructed. The unit 200 is configured.

  Further, as shown in FIG. 15, a special symbol display device 100 as a peripheral device, a sound effect generator 116,... Are connected to the main control unit 200. As described above with reference to FIG. 3, the special symbol display device 100 includes a CPU 1020, a program ROM 1040 that records this operation program, and a RAM 1090 that the CPU 1020 uses as work air. The sound effect generator 110 includes a CPU 1500, a ROM 1510 for recording the operation program, a speech synthesis LSI 11530 to which a speaker 1540 for amplifying speech is connected, and a RAM 1520 that the CPU 1500 uses as a work area. Yes. The CPU 1500 is configured to output a desired sound from the speaker 1540 by driving and controlling the sound synthesis LSI 1530 in accordance with a command from the main control unit 200.

  At least two of the plurality of peripheral devices described in FIG. 2 include a processor and a RAM used by the processor as a work area. In the example shown in FIG. 15, only the configuration diagram of the special symbol display device 100 and the sound effect generator 116 is described for ease of explanation. For example, in addition to this, peripheral devices such as the lamp display device 110 (112) and the normal symbol display device 108 are configured to include a processor and a RAM used as a work area by the processor, and the main control unit 200 controls the peripheral device. The thing etc. which were made to connect as possible may be used.

  Operation example 1 will be described with reference to FIG. First, in step S1700, the power-on switch 214 is turned on (operation for supplying power to the main control unit 200), and it is determined whether it is detected that the button A320 or the button B321 is pressed. To do. If such detection is not performed (No), a wait state is set in step S1700. On the other hand, if such detection is performed (Yes), the process proceeds to step S1710.

  In step S1710, the main control unit 200 determines whether the button pressing operation is performed by operating the button A320 or the button B321, and determines that the operation is performed by operating the button A320 (Yes). Then, the process proceeds to step S1720. In other cases (No), it is understood that the operation is performed by operating the button B321, and the process proceeds to step S1740.

  In step S1720 and step S1730, the main control unit 200 clears the A area 204 and turns on only the LED 311 to notify this. Thus, the lighting of the LED 311 is controlled so that the area A is cleared and can be seen. On the other hand, in steps S1740 and S1750, the main control unit 200 clears the B area 205 and turns on only the LED 312 to notify this. Thus, the lighting of the LED 312 is controlled so that the area B is cleared and can be seen.

  Therefore, according to the operation example 1, since only the corresponding divided area is cleared in response to the clear instruction operation of the divided area, only the desired divided area can be the target of the clear process. It is possible to prevent the clear processing up to the area that does not require clearing as in the prior art. In addition, a clear instruction operation is easy because the corresponding divided area is cleared in response to a pressing operation performed with any one of the buttons A320 and B321 for providing a memory clear instruction provided for each divided area. In addition, since the corresponding LED 311 or LED 312 is notified as a lighting state so that the cleared divided area can be understood, it is easy to grasp which divided area is cleared.

  FIG. 18 is an explanatory diagram of a table 1800 stored in the ROM 201 used in the operation example. The table 1800 registers the RAM clear priority of the peripheral device in association with the peripheral device to which the priority is assigned. In the example of FIG. 18, the priority orders “1”, “2”,... Are assigned to the special symbol display device 100 and the sound effect generators 116,. The main control unit 200 first transmits a control signal for clearing the RAM 1090 of the special symbol display device 100, and secondly generates a sound effect, after clearing one of the divided areas. The control signal for clearing the RAM 1520 of the device 116 is transmitted, and the control signal for clearing the RAM of the peripheral device is transmitted in accordance with the priority order registered in the table 1800. ing

  The operation will be described with reference to FIG. The operation shown in FIG. 19 is executed following the operation shown in FIG. Therefore, when a notification that any of the divided areas of the A area 204 and the B area 205 is cleared is performed, the operation shown in FIG. 19 is automatically executed. The main control unit 200 recognizes that the peripheral device with the priority “1” registered in the table 1800 is the special symbol display device 100. First, the main control unit 200 clears the RAM 1090 of the special symbol display device 100. A control signal instructing to do so is transmitted (step S1900). When the CPU 1010 receives this control signal, the entire memory area of the RAM 1090 is cleared (step S1910).

  Next, the main control unit 200 recognizes that the peripheral device with the priority “2” registered in the table 1800 is the sound effect generator 116 and instructs the RAM 1520 of the sound effect generator 116 to be cleared. A control signal to be transmitted is transmitted (step S1920). When the CPU 1500 receives this control signal, the entire memory area of the RAM 1520 is cleared (step S1930). Thus, the RAM on the peripheral device side is cleared according to the priority order. In FIG. 19, only the RAM clear on the two peripheral devices is shown for easy understanding. However, priorities are assigned including other peripheral devices, and 3 according to the assigned priorities. You may make it perform RAM clear of two or more peripheral devices.

  Therefore, according to the operation example 2, the main control unit 200 outputs a control signal for clearing the RAM in each of the plurality of peripheral devices with a preset priority order after clearing any of the divided regions. On the other hand, each of the peripheral devices includes a CPU (processor) and a RAM (random access memory) used as a work area by the CPU (processor). Since the memory area of the RAM is cleared in response to receiving the control signal from the control unit 200, each RAM of the plurality of peripheral devices can be automatically cleared according to the priority order. If the priority order is, for example, in order of increasing RAM capacity, clear processing can be performed in order from those requiring clear processing time.
