DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a half cutter and a tape printer having the same.

[0002]

2. Description of the Related Art Conventionally, printing is performed while feeding a tape-like member in which a printing tape and a release paper are laminated, and a half-cut portion is provided by a half-cutter so that the printed portion is easily peeled off. There is a tape printing apparatus that creates a label element by full-cutting a label element.

In a half cutter, a cutter and a tape receiving member usually face each other to form a cutting mechanism. And
Cutting is performed from one surface of the tape-shaped member by a cutter, and the other surface is pressed against the tape receiving member.
In particular, in the case of half-cutting, since the cutting depth into the tape-shaped member is very small, setting the distance between the cutter blade and the tape receiving member is very important. Also, the cutter blade
Usually, it is held by a cutter holder and a cutting operation is performed by a protruding portion from the cutter holder.

[0004]

As described above, the arrangement interval between the cutter blade and the tape receiving member is important. However, if the holding accuracy of the cutter blade by the cutter holder is low and the protrusion amount is not uniform, the cutter may be disturbed. The blade cannot be arranged at an accurate position with respect to the tape receiving member. As a result, the half-cut processing may be affected.

An object of the present invention is to provide a half cutter having a cutter holder capable of holding a cutter blade with an accurate protrusion amount, and a tape printing apparatus provided with the half cutter.

SUMMARY OF THE INVENTION A half cutter according to the present invention is a half cutter having a substantially square thin plate-like cutter blade constituted by an oblique blade and a cutter holder having a cutter holding portion for holding the cutter blade. The cutter holding portion includes a blade positioning portion that restricts the amount of protrusion of the cutting edge of the cutter blade by contacting one of two adjacent sides including the cutting edge of the cutter blade, and press-fitting the other two adjacent sides of the cutter blade. And a blade press-fit holding portion held by the blade.

[0007] According to this configuration, one of the two adjacent sides including the cutting edge of the cutter blade is brought into contact with the blade positioning portion, and the amount of protrusion of the cutting edge of the cutter blade can be regulated reliably, so that the projecting amount can be accurately determined. Can be set. Further, the other two sides adjacent to the cutter blade can be press-fitted into the blade press-fit holding portion to hold the cutter blade firmly.

In these cases, it is preferable that the cutter holding portion is constituted by a mounting groove having a shape substantially complementary to the cutter blade excluding the cutting edge.

According to this configuration, the cutter blade can be easily held on the cutter holder simply by overlapping the cutter blade on the mounting groove and pressing it from above.

In these cases, it is preferable that the blade positioning portion is constituted by two adjacent inner surfaces of the mounting groove.

According to this configuration, one of the two sides adjacent to each other including the cutting edge of the cutter blade as a whole except for the cutting edge portion,
Since the entire blade positioning portion is in solid contact, the amount of protrusion of the cutter blade from the cutter holder can be constant regardless of the variation in the outer shape of the cutter blade.

In these cases, the blade press-fit holding portion has a protruding portion that protrudes into the mounting groove, and the protruding portion is deformed so that the front end portion is crushed when the cutter blade is press-fitted, and the cutter blade is positioned with the blade. It is desirable to hold it immovably by pressing against the part.

According to this configuration, the projection is crushed by simply pressing the cutter blade from above, so that the cutter blade can be reliably held.

In these cases, it is preferable that the blade press-fit holding portion has an escape groove located around the protruding portion and in which the crushed distal end portion escapes.

According to this configuration, the crushed portion of the protruding portion escapes to the escape groove portion, so that the holding of the cutter blade by the blade press-fitting holding portion is not hindered.

As shown in FIG. 24, the drive mechanism of the rotating disk 460 includes a half-cut drive motor 466 and a gear train 467 for transmitting the rotating force to the rotating disk 460. The gear train 467 includes a worm gear 467a, a worm wheel 467b, and an intermediate gear 467c. The rotational force of the intermediate gear 467c is transmitted to the rotary disk 460 via a drive gear 468 formed integrally with the rotary disk 460. . As shown in FIG. 6, the half-cut drive motor 466 is disposed on the cutter support frame 160, and the gear train 467 is a drive unit mounting frame that is bent at right angles on the cutter support frame 160 and rises. 17
6.

As described above, the half cutting means 400
It has a dedicated half-cut drive motor 466 and a gear train 467 as its transmission mechanism.
0 has a dedicated full-cut drive motor 330 and a gear train 331. Therefore, the full cut means 300
And the half-cut means 400 are driven completely independently, so that the degree of freedom in combining the full-cut and the half-cut is increased. In addition, since only one of them is operated when necessary, there is an advantage that the blade life is extended.

As shown in FIGS. 9, 15 and 16, an input plate 470 is provided on one surface of a substrate 471 having a triangular shape or the like, and has an end face cam groove 462 of a rotating disk 460.
, A cam projection 472 constituting an end face cam mechanism is projected from the rotating disk 460, and a support shaft 473 and an engagement projection 474 are projected from the rear side thereof.

The support shaft 473 is connected to a support block 48 described later.
0, and is fixed to the cutter frame 170 in parallel with the rotating shaft 461 of the rotating disk 460,
It is configured to be swingable about the support shaft 473. The engagement protrusion 474 is fitted in an engagement recess 488a of a support block 480 described later 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 arranged in the sliding direction of the tape pressing member 420, and one end is provided on the side plate 42.
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 connected to a rotating disk 46 described later.
The rotation shaft 461 is inserted into a rotation shaft insertion hole 489 through which the zero rotation shaft 461 is inserted, and a retaining portion 484 is formed at the end 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 of 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, and a pin body or the like is provided on the mounting reference surface 170a of the cutter frame 170 as shown in FIG. Thus, it is disposed so as to slide forward and backward with respect to the tape receiving plate 440. In addition, the input plate mounting recess 48 that can be mounted so that the input plate 470 is superimposed on the substrate 481.
The input plate mounting recess 488 is further provided with a vertically long engaging recess 488a and a horizontally long hole 488b thereunder. The input plate mounting recess 488 has a size larger than the outer shape of the input plate 470, and the input plate 470 is
It is formed so that it can swing inside. Further, the substrate 481
A rotary shaft insertion hole 489 through which the rotary shaft 461 of the rotary disk 460 is inserted is formed below the input plate mounting recess 488.

The recess 488 of the support block 480
The input plate 470 is fitted therein, the support shaft 473 passes through the horizontally long hole 488b, and is fixed to the cutter frame 170, and the engagement protrusion 474 is fitted into the engagement recess 488a. This allows the input plate 470 to
Receiving the rotational force of the rotating 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 input plate 470 is transmitted by the support block 480 to the rotating shaft 461 of the rotating disk 460.
Can be converted into a reciprocating linear motion in a direction perpendicular to the direction. The support shaft 473 and the rotary shaft 46 of the rotary disk 460
1 is fixed, but does not hinder the reciprocating linear movement of the support block 480 because it is fitted into the horizontally long hole 488b and the rotary shaft insertion hole 489.

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.

Accordingly, 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 has 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 rotation disk 460. It is pivoted. The intermediate portion of the input arm 490 has a crank slot 492 that engages with a crank projection 463 protruding from the rotating disk 460 to form a swing crank mechanism with the rotating disk 460. An elongate hole 493 is formed at the tip end along the swing radius direction.

The elongated crank hole 492 is connected to the input arm 490.
A power non-transmitting portion 494 that cannot transmit the rotational force of the rotating disk 460 to the input arm 490 is formed at an intermediate portion thereof, and power can be transmitted only to both ends thereof. Power transmission parts 495 and 496 are formed.

Also, a long hole 493 at the tip of the input arm 490
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
When the rotating disk 460 is rotated via the gear train 467, the crank projection 463 is connected to the power transmitting portion 49 of the elongated crank hole 492 as shown in FIGS.
5, and can convert the rotational motion of the rotating disk 460 into a swinging motion from below to above the input arm 490. Further, the swing motion of the input arm 490 is
The cutter holder 450 is converted into a forward linear motion that rises along the guide shaft 402, and the cutter blade 410 can perform a cutting operation.

As shown in FIGS. 12 and 9, when the crank projection 463 is rotated while being engaged with the power transmission section 496, the rotation of the rotary disk 460 is controlled 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.
When the crank projection 463 is located at the power non-transmission portion 494 as shown in FIG. 7, the cutter holder 450 is stopped, so that a stop state is generated between the raising operation and the lowering operation of the cutter holder 450, and the intermittent operation is performed intermittently. It is possible to perform the elevating operation.

When the rotating disk 460 is rotated, as described above, the input plate 470 and the support block 48 are rotated.
0, the tape pressing member 420 and the cutter holder 45
0, since the blade positioning member 430 intermittently moves toward and away from the tape receiving plate 440, these separating operation and the raising and lowering operation of the cutter holder 450 are alternately performed as shown in FIG. 9 to FIG. Perform interlocking control to perform.

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 rotating disk 460 is rotated to bring the support block 480 close to the tape receiving plate 440 via the input plate 470. Thus, 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
The cutting preparation movement is performed to a cutting start position close to the tape receiving plate 440, and the pair of blade positioning members 430 is positioned by abutting on the tape receiving plate 440.

Next, as shown in FIG. 11, the rotary 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.
80 is released from the tape receiving plate 440 side, and the tape pressing member 420 and the cutter blade 410 are also followed and released. 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 rotating 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 detached 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, a complicated circulating cutting operation can be performed by the rotation force of one rotating disk 460, so that the operation 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-shaped member 210
During printing, there is a feature of shifting up (the platen roller 220
And the print head 150 is open at the top).
In this case, when cutting from top to bottom, the tape-shaped member 210
May be shifted, but if the cutting is performed from the bottom to the top, the tape-shaped member 210 is already close to the upper plate of the cartridge case or the like, so that there is no shift.

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 provided 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 cutout 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 the full cutter support frame 177, and the drive mechanism fully drives the full-cut drive motor 330 and the gear train 331. Rotational force is transmitted via a transmission gear 342, a gear train 343, and a drive gear 343 formed integrally with the lower end of the rotating shaft 515, which is shared with the cutting means 300 and is formed integrally with the rotating disk 340. That is, by operating the full-cut drive motor 330, the rotational force branches off from the rotating disk 340, so that the tape ejecting unit 500 can be synchronized so that the ejection operation of the tape ejection unit 500 is performed only during the cutting operation of the full-cut unit 300. it can.

Therefore, since the tape ejecting means 500 operates only during the full cut by the operation synchronizing mechanism, no pulling force acts on the tape member 210 during the printing or the 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.

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-shaped members 210 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 print data for the number of prints 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 means 300, L2 is the distance between the full cut means 300 and the half cut means 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 the length of one print data (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, if 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, in the control flow, if the OFF state of the detection switch is not detected for a predetermined time after the reverse rotation of the DC motor is started in S212 (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 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 short, or in the case where the power supply has been 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 when the stop of the cutter blade 410 has occurred, and to determine the optimal return direction of the cutter blade 410 at the time of restarting. 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.

[0104]

As described above, according to the present invention, one of the two adjacent sides including the cutting edge of the cutter blade is brought into contact with the blade positioning portion, so that the amount of projection of the cutting edge of the cutter blade is ensured. Because it can be regulated, the protrusion amount can be set accurately.
Further, the other two sides adjacent to the cutter blade can be press-fitted into the blade press-fit holding portion to hold the cutter blade firmly.
