That is, the cutter blade 410 held by the cutter holder 450 preferably has a cutting angle a of the cutting edge 411 in the slide cutting direction (the direction of the arrow) of not less than 20 ° and not more than 60 °. If it is less than this, the cut resistance becomes large, and if it is more than this, there is a possibility that cut bending may occur.

In the cutter blade 410, the cutting edge angle b of the cutting edge 412 is preferably set to 90 ° or more (obtuse angle). 90
If it is lower than the degree, it is easy to chip both at the time of blade processing and at the time of operation.
When the degree is higher than that, it is possible to prevent the chipping of the blade at the time of forcibly pulling out the tape-like member 210, to stabilize the sharpness of the tip, and to reduce wear.

Further, it is basically preferable that the cutting edge 412 of the cutting edge 412 of the cutter blade 410 is sharp, but it is chipped. Note that the cutter blade 410 may be formed of a cemented carbide. This is because ordinary tool steel and the like are easily worn and ceramics may be chipped.

The support shaft 473 is connected to a support block 48 described later.
0, is fixed to the cutter frame 170 in parallel with the rotation shaft 461 of the crank disk 460, and is configured to be swingable about the support shaft 473. The engagement protrusion 474 is provided on a support block 4 described later.
80 is fitted into the engaging recess 488a so as to be vertically movable.

As shown in FIGS. 9, 15 and 16, the support block 480 forms a flange 482 in the vertical direction at the end of the substrate 481 on the tape pressing member 420 side, in a direction perpendicular to the substrate 481. The flange 482 and the side plate 424 of the tape pressing member 420 are opposed to each other at an interval, and two upper and lower portions are connected by a connecting pin 483.

These connecting pins 483 are disposed in the sliding direction of the tape pressing member 420, and one end of the connecting pin 483 is
4, the other end slidably penetrates through the flange 482 of the support block 480, and a stopper 484 is formed at the tip. As a result, the support block 480 and the tape pressing member 420 are connected so as to be able to come and go.
The lower connecting pin 483 is protruded into a rotary shaft insertion hole 489 through which a rotary shaft 461 of a crank disk 460 described later is inserted, and a stopper portion 484 is formed at the tip thereof.

The side plate 424 of the tape pressing member 420
Has an appropriate number of spring storage holes 485a that reach the stored blade positioning members 430 and spring storage holes 485b formed in the middle of the spring storage holes 485a. The spring storage holes 485a and 485b and the support block 4
A spring 486a, a spring 486a,
486b is provided. One end of the spring 486a is connected to the spring receiving surface 43 of the blade positioning member 430 as described above.
1 abuts.

As described above, the tape pressing member 420 and the pair of blade positioning members 430 are independent from each other
The tapes 6a and 486b are urged toward the tape receiving plate 440 and operate without being influenced by each other, so that the reliability of each function is improved.

The substrate 481 of the support block 480 is provided with a horizontally long mounting slot 487 at an appropriate position. As shown in FIG. 6, a pin body or the like is provided on the mounting reference surface 170a of the cutter frame 170. Thus, it is disposed so as to slide forward and backward with respect to the tape receiving plate 440. Also, the cam follower mounting recess 48 that can be mounted so as to overlap the cam follower 470 is provided on the substrate 481.
The cam follower mounting recess 488 is further provided with a vertically long engaging recess 488a and a horizontally long hole 488b below it. The cam follower mounting recess 488 has a size larger than the outer shape of the cam follower 470, and the cam follower 470 has the cam follower mounting recess 488.
It is formed so that it can swing inside. Further, the substrate 481
The rotary shaft insertion hole 48 through which the rotary shaft 461 of the crank disk 460 is inserted below the cam follower mounting concave portion 488.
9 have been established.

The recess 488 of the support block 480
The cam follower 470 is fitted therein, the support shaft 473 passes through the horizontally long hole 488b, is fixed to the cutter frame 170, and the engagement protrusion 474 is fitted into the engagement recess 488a. Thereby, the cam follower 470 is
Receiving the rotational force of the crank disk 460, it swings around the support shaft 473 in the direction of arrow A as shown in FIG.

At this time, the engaging projection 474 is
The power in the horizontal sliding direction is transmitted to the support block 480 via the engagement recess 488a while moving up and down in the inside 88a. Therefore, the swinging power of the cam follower 470 is transmitted by the support block 480 to the rotating shaft 4 of the crank disk 460.
It can be converted into a reciprocating linear motion in a direction orthogonal to 61. Although the support shaft 473 and the rotation shaft 461 of the crank disk 460 are fixed, since the support shaft 4 is fitted in the horizontally long hole 488b and the rotation shaft insertion hole 489, the support block 4
It does not hinder the 80 reciprocating linear movements.

When the support block 480 makes a reciprocating linear motion, the tape holding member 420 via the connecting pin 483 and the cutter blade 410 attached via the cutter holder 450 to the guide shaft 402 held by the tape holding member 420.
In addition, the blade positioning members 430 fixed to the upper and lower ends of the guide shaft 402 follow the support block 480 and reciprocate linearly, so that the blade positioning members 430 can be separated from and attached to the tape receiving plate 440.

Therefore, the tape pressing member 420 can press the tape-like member 210 against the tape receiving plate 440 and release the pressing. Further, by causing the blade positioning member 430 to abut on the tape receiving plate 440, the cutter blade 410 can be arranged at a cutting operation position at a predetermined distance from the tape receiving plate 440. At this time, since the pair of blade positioning members 430 abut at two positions above and below the tape receiving plate 440, even if the structure such as the tape receiving plate 440 is deformed or the like, the tape receiving plate 44 is moved from the cutter blade 410 to the tape receiving plate 44.
The distance to zero can always be secured stably.

Further, the cutter holder 450 includes a spring 4
The biasing force of 86 a is transmitted via the blade positioning member 430 and the guide shaft 402. Therefore, the cutter holder 450 floats, and the cutter blade 410 elastically bites into the tape-like member 210. Therefore,
The tape-shaped member 210 is uneven along the unevenness of the tape receiving surface 441 of the tape receiving plate 440, and a cutting performance with a wide stable area can be obtained with respect to variations in tape rigidity such as when the cutting pressure of the cutter blade 410 is different.

Further, since the cutter blade 410 presses the tape-like member 210 against the tape receiving plate 440 in a cantilever state, the deformation of the tape receiving plate 440 is prevented, and the cutting accuracy is improved. Further, since the slide cutting operation is performed, cutting can be performed with an extremely weak force as compared with the push cutting method, and energy saving, miniaturization, and reliable cutting can be achieved. Further, since the printing tape 211 (receptor) is cut, it is easy to handle the completed label when performing continuous printing, serial number printing, and the like.

As shown in FIGS. 9 and 14, the input arm 490 has a base end on the outer surface of the drive unit mounting frame 176 by a support shaft 491 parallel to the rotation shaft 461 of the crank disk 460. It is pivoted. Input arm 49
In the middle portion of 0, an eccentric pin 463 protruding from the crank disk 460 is engaged, and has an elongated hole 492 constituting a swing crank mechanism with the crank disk 460. A long hole 493 is formed along the swing radius direction.

The elongated hole 492 is formed along the swinging radial direction of the input arm 490, and a power non-transmitting portion 494 in which the rotational force of the crank disk 460 cannot be transmitted to the input arm 490 is formed in an intermediate portion. Power transmission portions 495 and 496 capable of transmitting power are formed only on both ends thereof.

Further, a long hole 493 at the tip of the input arm 490 is provided.
The engagement protrusion 457d of the carriage 457 mounted on the cutter holder 470 is pivotally mounted on the input arm 490 so as to be slidable in the swing radius direction.

Therefore, the half-cut drive motor 466
Operates and the crank disc 460 rotates via the gear train 467, as shown in FIGS.
The eccentric pin 463 rotates in a state of being engaged with the power transmission portion 495 of the elongated hole 492, so that the rotational motion of the crank disk 460 can be converted into a swinging motion from below to above the input arm 490. Further, the swinging motion of the input arm 490 is converted into a forward linear motion in which the cutter holder 450 rises along the guide shaft 402, and the cutter blade 410 can perform a cutting operation.

When the eccentric pin 463 is rotated with the eccentric pin 463 engaged with the power transmission section 496 as shown in FIGS. 12 and 9, the rotational movement of the crank disk 460 is changed by the input arm 490. It can be converted to rocking motion from top to bottom. Further, the swinging motion of the input arm 490 is converted into a return straight-line motion in which the cutter holder 450 descends along the guide shaft 402. 9 and FIG.
The eccentric pin 463 is connected to the power non-transmission portion 49 as shown in FIG.
In the case of position 4, since the cutter holder 450 is stopped, a stop state is generated between the raising operation and the lowering operation of the cutter holder 450, so that the cutter holder 450 can be intermittently moved up and down.

When the crank disk 460 rotates,
As described above, the tape pressing member 420, the cutter holder 450, and the blade positioning member 430 intermittently move toward and away from the tape receiving plate 440 via the cam follower 470 and the support block 480. As shown in the order of FIGS. 9 to 12, the raising and lowering operation of the cutter holder 450 is controlled so as to be alternately performed.

First, FIG. 9 shows a state in which the tape pressing member 420 has released the tape-shaped member 210 and the transport printing is being performed, and the cutter blade 410 has been cut away from the lower end of the tape receiving plate 440. It is in the standby position. Next, as shown in FIG. 10, the crank disk 460 is rotated, and the support block 48 is rotated via the cam follower 470.
0 is brought close to the tape receiving plate 440. by this,
The tape pressing member 420 fixes the tape-shaped member 210 by sandwiching the tape-shaped member 210 with the tape receiving plate 440. Also, the cutter blade 410
Is moved to a cutting start position close to the tape receiving plate 440, and is positioned by the pair of blade positioning members 430 contacting the tape receiving plate 440.

Next, as shown in FIG. 11, the crank disk 460 is rotated, the cutter blade 410 is slid up through the input arm 490, and the tape-like member 210 is cut. Next, as shown in FIG. 12, the support block 480 is detached from the tape receiving plate 440 side, and the tape pressing member 420 and the cutter blade 410 are also detached while following. As a result, the tape-shaped member 210 is released from the tape pressing member 420 again, so that transport printing can be performed. Further, the cutter blade 410 performs a detaching operation to a predetermined detaching position.

Finally, as shown in FIG. 9, the crank disk 460 is rotated, the cutter blade 410 is slid down through the input arm 490, and the cutter blade 410 is returned from the disengaged position to the cutting standby position. The operation is performed. The cutting operation can be repeated by circulating and repeating the above operation.

As described above, one crank disk 460
Since a complicated circulating cutting operation can be performed with the above rotational force, it can be efficiently performed with a simple mechanism. In addition, accurate synchronization of each operation becomes possible. In addition, the tape-shaped member 210 is cut from the bottom to the top, and the cutter blade 410 is positioned below the tape-shaped member 210 at the time of cutting standby, so that the cutter blade 410 does not hit the tape-shaped member during tape replacement. . Further, the tape-like member 210
Has the characteristic that it shifts up during printing (platen roller 2
20 and the print head 150 are open at the top). In this case, when cutting from top to bottom, the printing position of the tape-shaped member 210 may be shifted, but when cutting from bottom to top, the tape-shaped member 210 is already close to the upper plate of the cartridge case or the like. There is no deviation.

As shown in FIG. 1, the tape discharge means 500 includes a half cut means 400 and a tape discharge port 110.
And forcibly ejecting the tape-like member 210 cut and separated by the full-cut means 300 from the tape ejection port 110. For example, FIG.
As shown in FIGS. 7 and 8, the tape-shaped member 210 has a discharge roller 510 that is disposed on the side of the release paper 212 and rotates in a direction in which the tape-shaped member 210 is discharged in contact with the tape-shaped member 210. .

The discharge roller 510 is provided with a rotating base 511.
And a tape discharge unit 512 provided thereunder.
The tape discharge section 512 is formed by a plurality of hanging pieces 513 hanging from the peripheral edge of the rotating base 511,
The third group expands in a divergent shape by centrifugal force generated during the rotation operation of the discharge roller 510, and taps the cut tape-shaped member 210 out of the tape discharge port 110.

The discharge roller 510 is disposed on the back surface 446 side of the tape receiving surface 441 of the tape receiving plate 440 (at a position facing the half-cut means 400), and cuts out the notch 443 opened in the tape receiving plate 440. It is configured so as to face the cutter blade 410 side. The holding plate 403 d formed on the cutter cover 403 and the discharge sub-roller 51 disposed opposite to the discharge roller 510.
By 4, the tape-shaped member 210 is pinched to facilitate discharge.

Further, as shown in FIG. 7, the discharge roller 510 is supported by a rotating shaft 515 erected on a full cutter support frame 177, and the drive mechanism fully drives the full-cut drive motor 330 and the gear train 331. A transmission gear 342, a gear train 343, and a rotating shaft 515 which are shared with the cutting means 300 and are formed integrally with the crank disk 340.
The rotational force is transmitted via a drive gear 343 integrally formed at the lower end of the motor. That is, the full-cut drive motor 330
, The rotational force branches off from the crank disk 340, so that the tape ejecting unit 500 can be synchronized so that the discharging operation of the tape discharging unit 500 is performed only during the cutting operation of the full cutting unit 300.

Accordingly, since the tape ejecting means 500 operates only during the full cut by the above-mentioned operation synchronizing mechanism, no pulling force acts on the tape-like member 210 during printing or half-cut, so that there is no influence. Further, the tape discharging means 50
By arranging 0 on the release paper 212 side, it is possible to easily discharge along the curl habit of the tape-like member 210 and not to hit the printing tape 211 side, so that the printing surface is not stained or scratched.

Further, since the tape discharging means 500 and the half cutting means 400 are arranged to face each other, the distance between them in the tape feeding direction can be shortened. Therefore, since the discharge margin can be small, waste of the tape-shaped member 210 can be reduced. In particular, if the discharge roller 510 is configured to bite into the cutout portion 443 of the tape receiving plate 440, the waste of the tape-shaped member 210 is reduced. Further, the full cut means 30
By arranging the half-cut unit 400 and the tape discharge unit 500 in this order, the distance from the position where the print head 150 is disposed to the full-cut position can be minimized, and waste of the tape-like member 210 can be reduced.

At 0, various display LEDs 682 are connected to the gate array 630. The power control 690 and the AC adapter 691 are connected to various motors and the CPU 600.

The CPU 600 is a control unit for performing overall control of each device.
With respect to 0, the half-cutting means 400 can perform the cutting operation in advance. It is also possible to independently control the full-cutting means 300, the half-cutting means 400, the tape feeding means including the platen roller rotating shaft 143 and the platen roller 220, and the printing means including the print head 150 and the like.

Next, the transport printing method will be described with reference to FIGS. 26 and 27. First, the matrix key 66
From one input unit, print data for one print data consisting of print data to be printed, format data such as character size, character spacing, number of lines and margins before and after, and delimiter data for half-cutting each sheet And the number data of how many copies of the same tape as this print data are to be printed.
When an instruction to start printing on the print data is issued, the printing process is started.

Here, the CPU 600 controls the tape feeding means and the half-cutting means 400, and controls one of the tape-like members 210 to be cut off by the full-cutting means 300.
Half-cutting is performed on the main print label component from the upstream end in the tape feed direction with a separation margin. Further, the tape feeding means, the print head 150 and the half-pitch are so arranged that the sum of the peeling margin and the front margin of the printing part in the printing label constituting part is equal to or larger than the separation distance between the printing head 150 and the full cutting means 300. Cutting means 400
Control. Furthermore, when printing is performed continuously without separating a plurality of print elements, the separation and separation margins by the full cut unit 300 are canceled at the boundary portion of each print element, and only the half cut by the half cut unit 400 is performed. Control to be performed.

When the printing process is started, first, the input number of print data is expanded and stored in the RAM as image data for printing (S100).
In another area of M, the length of one tape as a half-cut position and the length of one tape as a full-cut position are obtained and stored from the number of characters, character size, line spacing, and margins. Based on the image data and the tape length data obtained from the print data, transport printing to the tape member 210 is performed (S101).

In FIG. 26, L1 is the distance between the print head 150 and the full-cut unit 300, L2 is the distance between the full-cut unit 300 and the half-cut unit 400, and FIG. In the state of the previous tape-shaped member 210, printing is started while feeding the tape from this state,
After the tape is transported and printed by the length L1 (S102), the printing operation and the feeding operation are temporarily stopped as shown in (b) and (c) in the drawing, and the full cutting is performed by the full cutting means 300 (S103). Then, cut off the excess tape part (hatched part). Next, as shown in (c) in the figure, the remaining print portion of one print data (three characters of ABC in this embodiment) is printed (S104). Next, as shown in (d) in the figure, after carrying and printing the length L1 + L2 (S105), the printing operation and the feeding operation are temporarily stopped, and half cutting is performed by the half cutting means 400 (S106).

Thereafter, it is determined whether or not to continue the linked printing (S107). If not, the transport printing is performed by subtracting the length of L2 from one print data length (S108). , Pause printing and feeding operations,
Full cut is performed by the full cut means 300 (S1
09). As a result, the label element of two print data lengths having a half cut portion in the middle is cut off, and the remaining tape-like member 210 has no shaded portion in FIG. Next, as shown in (c) in the figure, the remaining print portion of one print data is printed (S110), and the printing is completed. At the start of the next printing, the printing process can be performed from a state where there is no extra portion of the tape.

In the printing process flow, when the continuous printing is to be continued in S107, the transport printing is performed for one printing length (S111), and then the printing operation and the feeding operation are performed as shown in FIG. Is temporarily stopped, and the half-cutting means 4
The half-cut is performed by 00 (S106). Next, it is determined again whether or not to continue the linked printing (S10).
7) If the printing is not to be continued, as shown in (f) in the figure, after the transport printing is performed for the length obtained by subtracting the length of L2 from the length of one print data (S108), the printing operation and the feeding operation are temporarily performed. After stopping, the full cut is performed by the full cut means 300 (S109). As a result, the label element of three print data lengths having two half-cut portions in the middle is cut off, and the remaining tape-like member 210 is in a state without the hatched portion in FIG. Next, as shown in (c) in the figure, the remaining print portion of one print data is printed (S1
10), end printing. At the start of the next printing, the printing process can be performed from a state where there is no extra portion of the tape.
If the combined printing is to be further performed, S107, S11
1, S106 is repeated.

Next, the half cut control will be described with reference to the flowchart of FIG. Tape printer 1
When the main power of 00 is turned on (S200), first, it is confirmed whether or not a detection signal is output from the cutter home position detector 465 (S201). When the OFF state of the detection switch of the cutter home position detector 465 is detected, the half cutter 401 is in a steady state of the cutter home position and waits for a half cut command (S20).
2). When there is a half-cut command (S203), the DC motor starts normal rotation (S204), and the ON state of the detection switch of the cutter home position detector 465 is detected (S2).
05), a half cut is performed (S206). Next, when the OFF state of the detection switch is detected (S20).
7) After performing the DC motor brake control (S20)
8) The DC motor is stopped (S209), and the half cutter 401 is returned to the steady state again to wait (S2).
02).

Here, the present apparatus includes a half cutter 401.
When the OFF state of the detection switch is not detected for a predetermined time (for example, 3 seconds) after the half cut is started in S206 (S210), the cutting operation of the half cutter 401 is performed. Since the abnormality is abnormal, after stopping the DC motor (S211), the half cutter 401 is reversely rotated to perform the reverse rotation operation (S212). Thus, when the OFF state of the detection switch is detected (S213), the DC motor is stopped (S214), the main power is turned off (S215), and the half-cut control is ended.

Here, if the OFF state of the detection switch is not detected for a predetermined time after the start of the reverse rotation of the DC motor in S212 during the control flow (S21).
6) Immediately after the lapse of time, the main power is turned off (S
217), end the half-cut control.

In the control flow, S201
The presence or absence of a detection signal output from the cutter home position detector 465 is confirmed, and if the ON state of the detection switch of the cutter home position detector 465 is detected, the half cutter 4
Since 01 is not at the cutter home position, the DC motor is rotated forward to rotate the half cutter 401 forward (S218). Thus, when the OFF state of the detection switch is detected (S219), the DC motor is stopped (S220), and the half cutter 401 enters a steady state (S202). After the forward rotation operation (S218), if the OFF state of the detection switch is not detected within a predetermined time, the control after S210 in the control flow is performed.

Further, the present apparatus has a detecting means for detecting various abnormal cases other than the abnormal operation of the half cutter 401. The various abnormal cases are, for example, cartridge lid open detection, power key OFF operation, head overheat detection, and the like. FIG. 29 shows a half-cut control flow when the above-described various abnormal cases occur. First, when various abnormal cases are detected by the abnormal case detecting means during the execution of the half cut, the detection signal interrupts the flow of the half cut execution (S300). In this case, the DC motor is continuously driven until the detection switch is turned off, and the half cutter 401 is returned to the cutter home position (S301). Thereafter, the DC motor brake control is performed (S302), the DC motor is stopped (S303), and the main power is turned off (S30).
4) Terminate the execution of the half cut.

FIG. 30 shows a control flow in the case where the battery life is very short, or in the case where the power supply is cut off due to the removal of an outlet or a power failure. When such an abnormal case related to the natural disconnection of the main power supply is detected, the detection signal is interrupted during the half-cut execution flow (S40).
0). In this case, a positive operation stop command is not issued for control, and the operation is left as it is. However, if there is a restriction on hardware or software (such as an undefined state prevention process at the time of restoration), it is followed. If left unattended, the DC motor becomes inoperable (S401), the main power supply is naturally turned off (S402), and the execution of the half cut ends.

As described above, by detecting both the position of the cutter blade 410 and the operation time thereof, it is possible to identify the cause of the stoppage of the cutter blade 410, and to determine the optimum return direction of the cutter blade 410 when the cutter blade 410 is restarted. Decisions can be made to minimize any adverse effects on the system. 28 to 30 described above.
Has been described for the case of the half-cutting means 400, but the same control is also possible for the full-cutting means 300.
