DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape printer for printing a character or graphic on a tape-shaped printing material, and more particularly to a tape printer having a tape cutting means for cutting a tape.

[0002]

2. Description of the Related Art Conventionally, as a tape printer of this kind,
For example, JP-A-2-147272 (US Pat. No. 4,83,669)
No. 7) is known. This tape printer includes a feed roller that feeds a print tape and an ink ribbon in an overlapped state, and a tape printing unit having a thermal head that performs printing on the print tape via the ink ribbon. There is provided a tape cutting means for cutting a printed portion of the print tape which has been separated and sent out of the apparatus. Tape cutting means,
A cutter consisting of a fixed-side blade mount and a movable-side cutter blade, a cutter motor with a speed reducer that allows the cutter blade to move forward and backward, and a power conversion that transmits the rotation of the cutter motor to advance and retreat of the cutter blade Screw mechanism.

When the cutting button is pressed, the cutter motor rotates, advances the cutter blade, inserts the printing tape between the cutter mount and the blade mount, and cuts the printing tape in a push-cut manner. When the cutter blade completely overlaps the blade mount, the cutter motor then rotates in the reverse direction, and retracts the cutter blade to its original position (home position).

[0004]

In such a conventional tape printer, when the power is turned off while the cutter blade is moving, the cutter blade stops at an intermediate position without returning to the home position. In particular, if the cutter blade is stopped in a state of being overlapped with the blade mount, when the power is turned on next and printing is started, there is a possibility that the printing tape which is sent out may be held by the cutter blade and jamming may occur. In addition, when the cutter blade overlaps the blade mount, there is a problem that it becomes an obstacle when setting the printing tape.

An object of the present invention is to provide a tape printer capable of stably cutting a tape-shaped member without causing jamming or the like.

[0006]

SUMMARY OF THE INVENTION A tape printer according to the present invention comprises a tape printing means for printing on a tape-like member while feeding the tape-like member, and a tape for cutting off the tape-like member by stopping the feed of the tape-like member. In a tape printer including a cutting unit and a control unit for controlling a cutting operation of the tape cutting unit, the tape cutting unit is formed in a scissor shape and cuts in an open leg state for receiving a tape-shaped member to be sent. A cutter configured to be movable between a standby position and a cutting position in a closed leg state for cutting the received tape-shaped member, wherein the control unit moves the cutter to the cutting standby position in conjunction with power-on It is characterized by making it.

According to this configuration, the control means turns on the power.
When the printing is started, the cutter is in the cutting standby position and is in a state capable of receiving the tape-shaped member to be sent. For this reason, even if printing is started and the tape-shaped member is sent to the position of the cutter, the tip of the tape-shaped member does not catch on the cutter.

In this case, there is further provided a detector for detecting that the cutter has moved to the cutting standby position, and the control means activates the cutter on the basis of the power ON signal and also detects the detection signal of the detector. It is preferable that the operation of the cutter is stopped by pressing the cutter.

According to this configuration, since the operation of the cutter is stopped by the detection signal of the detector, the power is turned on.
Thus, the cutter can be accurately stopped at the cutting standby position, and the cutter can always be kept at a fixed position before cutting.

In these cases, the control means controls one cutting operation of the cutter by time.
It is preferable to output an error signal when the detection signal of the detector is not input even after a lapse of one disconnection operation from the input of the N signal.

According to this configuration, the user can be informed by the error signal that the cutter is not operating correctly, and it is easy to find damage to components, control failure, and the like. In addition, it is preferable that an error display or a buzzer notification is made by the error signal.

An arrow A30 indicates a tape feeding direction, 217 indicates a blank tape corresponding to a distance between the head position and the cutter position, and 210 indicates the length. Reference numeral 211 denotes a tape length, which is a sum of a front margin 212, a print range 213, and a rear margin 214. 215 is a tape width and 216 is a print width.

In the initial state, the print head 105 is located at H1. When a print command is received, the tape is fed by the front margin 212 minutes. Printing starts when the print head 105 reaches the position H2. When the leading edge of the front margin comes to the cutter position after the start of printing, the print head 105 is at the position of H3, stops printing, and performs cut processing. When printing is restarted after cutting and printing is completed, the print head 105 is positioned at H4. Printing is stopped, and the tape is fed for the rear margin 214. At this time, it is located at H5. Then, in order to obtain a printed piece of tape, the tape is sent after a head cutter distance of 210 minutes, and then cut (the position of the print head 105 is H6). At this time, the tape having the head cutter distance of 210 is useless. A method for eliminating the waste will be described later.

Now, an embodiment of the present invention will be described in order to prevent vertical voids between dots at the time of cutting. One of the methods is a step motor hold control, and the other is a method of reversing the tape before and after the tape is cut.

First, the hold control of the step motor will be described. In the present embodiment, examples are given for two methods. One is current control, and the other is chopping control.

FIG. 8 is a schematic diagram of a drive control circuit for a step motor. FIG. 9 is a timing chart showing a driving method of the drive control circuit of FIG. FIG. 10 is a timing chart in which the step motor hold control is realized by the motor drive control.

The drive control circuit of the step motor shown in FIG.
7 and a transistor 236 that bypasses a large current. When the hold signal 235 is input, the transistor 236 is turned off and the current flows through the current limiting resistor 237. When the hold signal 235 is not input, the transistor 236 is turned on, so that a large current can flow. In this way, the rotation of the step motor is stopped, and the holding state is established with low power. In the figure, reference numeral 230 denotes a step motor drive driver, and reference numerals 231, 232, 233, and 234 denote 1, phase, two, three, and four phase terminals of the step motor, respectively.

In FIG. 9, 240, 241, 242,
Reference numerals 243 denote step motor one-phase, two-phase, three-phase,
These are four-phase timing signals. Reference numeral 244 denotes a hold signal. The sections T1 and T3 are rotation control sections of the step motor, and the section T2 is a hold control section.
As described with reference to FIG. 8, when the hold signal 244 is HIGH (section T2), the transistor 236 is turned off, and the step motor 122 is held with low power.
In this section T2, the printed tape is cut. In the figure, holding is performed in four phases.

FIG. 10 shows that the hold control of the step motor is realized by so-called chopping control for intermittently controlling the drive signal of the excitation phase. The drive control circuit of the step motor is shown in FIG. The transistor 236 and the hold signal 235 are deleted. T1 and T3 are rotation control sections, and T2 is a hold control section. 240, 241, 242, 2 in the figure
43 is a step motor of one phase, two phases, three phases,
These are the timing signals for each phase.

Next, a method of reversing the tape before and after the tape cut will be described.

FIG. 11 is a timing chart for reverse / forward rotation of the tape feed before and after tape cutting. In the figure, reference numerals 240, 241, 242, and 243 indicate one-phase, two-phase, three-phase, and four-phase drive signals of the step motor 103, respectively. Reference numeral 250 denotes a head energization signal, 251 denotes a cutter start signal, 252 denotes a detection signal of a cutter home sensor,
44 is a head hold signal. In the T1 section, normal tape feeding (t1, t2, t3, t4) and energization (t5)
It is carried out. T6 indicates a tape feed time for one dot row. When it reaches the cut position, the tape feed is reversed (T
4) Perform tape cutting (T2). Thereafter, the reversed tape is rotated forward and the tape is returned to the position before cutting (T
5). Then, tape feeding and printing are restarted (T3). At the time of tape cutting, as described above, the tape is held by the hold signal 244 of the step motor or the chopping control. DC motor 1 that drives the cutter during that time
46 is activated by the cutter drive signal 251. A signal indicating that the auto cut has been completed is output to the cutter home detector 1.
Since the home position detection signal 252 is output from the output unit 59, the auto cutter driving signal 251 is stopped when the home detection signal 252 is detected. Next, the hold signal 244 is stopped and the printing operation is restarted. T1, t in the figure
2, t3 and t4 are one phase of the step motor 1 and 2
, Three-phase, and four-phase drive pulse times, t5 is the power supply time of the print head 6, t7 is the drive time of the cutter, and t8 and t
Reference numeral 9 denotes a pulse time of the cutter detector, and t6 denotes a time from when the tape is reversed to when the power source is stabilized and the cutter is driven.

FIG. 12 shows the state of the double-sided adhesive tape and the transparent tape at the time of tape cutting. In the figure, the double-sided adhesive tape 152 and the transparent tape 151 are
Usually pulled by the tension of the tape feed,
152-1 and 151 respectively due to the reversal of the tape feed
It becomes a slack state like -1. At this time, at the position of the print head 105, the transparent tape 151 and the ink ribbon 153 are pressed against the print head 105 and the platen roller 149 and do not move. When the tape is cut here, the double-sided adhesive tape 152-1 and the transparent tape 151-1
Is pulled by the cutter and sent slightly, but again, the transparent tape 151 and the ink ribbon 153 are
5 and the platen roller 149, so that there is no movement.
After the tape is cut, the tape feed is rotated forward, and the double-sided adhesive tape 152-1 and the transparent tape 151-1 return to the original stretched state. When the motor is rotated forward, the pulse is returned by a smaller number of pulses than when the motor is rotated in the reverse direction, so that it is controlled not to be pulled out extra.

FIGS. 13A and 13B show the effectiveness of the reversal.
Will be described. 13 (a) and 13 (b) are schematic diagrams of the engagement portion between the step motor gear 122 and the transmission gear 123. FIG. 13A shows a stopped state during normal tape feeding, and FIG. 13B shows a stopped state during reverse rotation. When rotating in the direction of arrow A31 in FIG. 13A, the tape is sent out. When the cutter is operated in this state, the tape is pulled in the direction of arrow A32, and the transmission gear is moved to the position indicated by the broken line 1.
It moves like 23 '. In the state of FIG. 13B, the tape is rotated in the direction of arrow A33, and the transmission gear 123 cannot move even if the cutter operates and is pulled in the direction of arrow A34. The phenomenon of FIG. 13A is caused by the fact that all the gears 125, 1
27 and 128, it is easy to pull out the tape at the time of cutting, and the amount is also accumulated.

FIGS. 14, 15, and 16 are control flowcharts including the reverse rotation at the time of tape cutting.

In FIG. 14, LM is a front margin, P
L indicates a print length, RM indicates a rear margin, and C indicates a dot counter value for tape feed. N is a numerical value obtained by converting the tape feeding distance between the head cutters into dots. These variables are
It is secured in the work area 61 in the RAM 57.

When printing is started (step 300),
First, the front margin setting value (LMGN) in the RAM 57
From 68, the front margin LM is calculated. This calculation calculates millimeters to dots. (Step 301) LM = LMGN (mm) / d1 (d1 is the distance between the dots for feeding the tape. See FIG. 6) Next, the print length PL is calculated. The print length PL is the print character width (WIDE) 64, the number of characters, and the space between characters (CSP).
C) Calculate at 66. (Step 302) PL = WIDE × number of characters + CPSC × (number of characters−1) Next, the rear margin RM is calculated. Rear margin RM
From the tape length setting (TLNG) 67 to the front margin L
What is necessary is to subtract M and the print length PL. (Step 303) RM = TLNG-LM-PL If the calculated rear margin RM is negative, an error occurs because the set value of the tape length is short. (Steps 304 and 3
05) Initialize the dot counter C for tape feed. (Step 306) First, the tape is fed by the front margin (S1). That is, until LM becomes 0 (step 309), one dot advance (step 311) and LM are decremented by one, and the counter C
Is incremented by 1 (step 310). At this time, it is checked whether the value of C has reached the cutting position by comparing C and N. (Step 307) When the cut position is reached, cut control A is performed. (FIG. 15) Similarly, a printing operation is performed (S2). (Steps 312-
317) The printing operation is different from the tape feeding of the front margin in that one dot row is printed for each dot feeding (step 317), and cut control B is performed (step 3).
13) That is. The difference between the cut control B and the cut control A is whether the tape feed is reversed or forward.

As in the case of the front margin, tape feeding of the rear margin is performed (S3). (Steps 318 to 322) The cutter position comes in the front margin tape feed, print tape feed, and rear margin tape feed (C = N).
Is always performed once, so that the cut is performed at any one of the steps 308, 313, and 319 of the cut control.

After the rear margin is fed, the tape is cut. After the N dot tape has been fed (step 323), the cut control A is performed (step 324), and the print control ends (step 325).

FIG. 15 is a flowchart of the cut control A (when the reverse rotation is not performed). In the figure, T is the CPU 5
0 is a timer inside (not shown), and TN is a cutter timeout time. First, a timeout time TN of the timer T is set. (Step 331) Then, the DC motor 146 for driving the cutter is started (Step 332). Signal of cutter home sensor 159 is ON
(Step 333), the timer T is decremented by one (step 334). When the timer T reaches 0, it is determined that a timeout has occurred (step 335), and a cutter operation error is determined (step 336). If the cutter home sensor 159 is turned on before the timeout, the sensor 159 is turned off (step 337), and the DC
The motor is stopped (step 338) and the process ends (step 339).

FIG. 16 shows a cut control B (in the case of reverse rotation).
It is a flowchart of FIG. In the figure, W1 is the number of reverse rotation steps, W2 is the number of forward rotation steps, and W2 ≦ W1 is always satisfied.

In the cut control B, before the cut control A is called (step 342), the reverse transfer of the tape for W1 dot is performed (step 341).
The normal transfer of the tape for the dot is performed (step 34).
3).

FIG. 7 shows the cut control during printing.
Tape printing that cuts at the front and rear margins becomes possible.

Next, the means for setting the front margin and the tape length will be described.

FIG. 17 is a flowchart of a main control routine of the tape printer of the present invention. Power ON (Step 35
0) First, system initialization is performed (step 351). Subsequently, the printer mechanism is initialized (step 35).
2). In the initialization of the printer mechanism, the cutter is moved to the home position. At 353, the characters in the edit buffer 58 are displayed, and a key input is waited for (step 354). If the input key is a character key (step 355), it is input to the editing buffer 58 (step 356). If it is not a character key, the control key is determined (step 358), and the operation is performed according to the control key. The SHIFT key and the CAPS key wait for input of the next character (steps 359 and 362).
If the entered key is a character key (steps 360, 3
63) and convert them to symbols and capital letters, respectively (step 36)
1,364) Input to the edit buffer. If it is not a character key, the key is ignored and the next key is waited for (step 354). In the control key determination, if it is a FUNC key, the next key is waited for input (step 365), and if it is a character key (step 366), a function key determination is made (step 367) to activate a function function. In the function key determination, if the input keys are numeric keys 1, 2, 3, 4, 5, and 6, character height setting (step 371), character width setting (step 372), and character decoration setting (step 373), respectively. ), Character space setting (step 374), tape length setting (step 375), and front margin setting (step 376). The numeric keys are arranged at predetermined keys on the keyboard 20 in FIG. If it is a print command key, repeat printing is performed (step 377). Control key determination (step 35
In step 8), if the command is a print command key, a printing process is performed (step 368). If the command is a cursor key, the cursor is moved (step 369). If the command is a line feed key, a line feed operation is performed (step 370).

In setting the tape length (step 375) and setting the front margin (step 376), the display device 1
The heading and the current set value are displayed in units of millimeters on 5 and the numerical value is moved up or down with the cursor keys, or the numerical value is directly input with the numerical keys, and the numerical value is determined with the line feed key. Here, the means for setting the rear margin is unnecessary. That is, if there is a tape setting unit, a front margin setting unit, a character width setting unit, and a character space setting unit, the rear margin is automatically determined.

Finally, a description will be given of print control that does not create a blank space on the tape between the head cutters. In the above, repeat printing (step 377) is such.

P1 indicates the position of the print head 105, P2 indicates the position of the cutter blade, and L indicates the distance between the head cutters. In the figure, (a) shows the state of the tape before printing. Printing is started while feeding the tape from this state, and when the tape is fed by the length L to the left, temporary printing and tape feeding are stopped ((b) ) State). When the tape is cut in this state and an unnecessary portion (hatched portion in the figure) is cut off, the state shown in FIG. After the tape is cut, the printing and the tape feeding are restarted, and the state in which the printing is completed is shown in FIG. Here, when there is no schedule for the next printing and the user wants to output a piece of tape (to finish the printing operation), the tape is fed leftward by L and the tape is cut in the state shown in FIG. A piece of tape printed with "ABC" without the mark is output. On the other hand, when the printing operation is continued, the second printing is started while the tape is being fed from the state of (d), and the temporary printing and the tape feeding are stopped when the tape is fed by the length L in the left direction (( e) state). In this state, when the tape is cut and the tape piece on which “ABC” is printed is cut off, the state shown in FIG. After the tape is cut, the printing and the tape feeding are restarted, and the state in which the printing is completed is shown in FIG. As described above, in order to continuously output a piece of tape on which “ABC” is printed, first, the operations (a) and (b) are performed, and then the operation shown in FIG.
By repeating the operations (c), (d), and (e) in FIG. 8, only a wasteful tape having a length L (a shaded portion in the drawing) is generated first, and the output tape piece is No useless parts are included.

FIG. 19 is a flowchart showing a label producing process in the tape printer according to the embodiment of the present invention. First, printing is performed on the tape for a length L (the distance between the printing position and the tape cutting position) (step 381), where printing is temporarily interrupted, and the tape is reversed for W1 steps (step 382). After cutting (step 383), the tape is rotated forward by W2 steps (step 384), and the remaining printing (step 385) is restarted. After the printing is completed, it is determined whether or not to perform the next printing (step 386). If the next printing is to be performed, the process returns to printing (step 381). If not, the tape is fed by the length L (step 387). ), Cut the tape (step 388) and finish (step 3)
89).

The determination in step 386 may be such that the user sets the number of repeats immediately before repeat printing and counts down until the number of repeats becomes zero.

Although the present embodiment has been described with respect to the case where tape pieces printed with "ABC" are continuously output,
There is no problem if the characters or figures to be printed are changed each time and the printing is performed continuously.

FIG. 20 is a flow chart showing another embodiment of the control process in the tape printer of the present invention, and the same processes as those in FIG. 19 are denoted by the same reference numerals. First, printing is performed on the tape for a length L (the distance between the printing position and the tape cutting position) (step 381), where printing is temporarily interrupted, and the tape is reversed for W1 steps (step 382). After cutting (Step 3
83), the tape is rotated forward by W2 steps (step 3)
84) Restart the remaining printing (step 385). After the printing is completed, an inquiry is made to the operator as to whether or not to perform the next printing by using the display means. (Step 390) As an example, "Con
tinue? (Y / N) "is displayed. Here, the key input is waited (step 391), and after the key input, the process proceeds to the step of judging by the input character (step 392). If the input is" Y ", printing is performed (step 381). Returning, if printing is not continued by inputting "N", the tape is fed by the length L (step 387), the tape is cut (step 388), and the processing is terminated (step 389), even if the input of "Y" or "N" is awaited. When a numerical value is input, it can be applied to execute repeat printing this number of times.

[0056]

As described above, according to the tape printer of the present invention, when the power is turned on, the cutter moves to a state in which the tape-like member can be received, so that printing starts and the tape-like member moves to the position of the cutter. Even if it is sent, the tip of the tape-shaped member does not catch on the cutter. Therefore,
The tape-shaped member can always be stably cut without causing jamming or the like.
