DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a half-cut device 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. Conventional half cutters are disclosed, for example, in Japanese Patent Laid-Open No.
As disclosed in Japanese Patent No. 0893, a push-cut type in which a cutter blade moves in a direction perpendicular to the tape surface of the tape-shaped member (contact direction) to perform a cutting operation is used.

[0003]

The push-cut type half-cutter as described above has a large contact area because the blade edge of the cutter blade contacts the entire length of the tape-shaped member in the width direction. And crush it to make a cut. Therefore, a large force is required for cutting, which is not preferable from the viewpoint of energy saving, downsizing of the tape printing apparatus structure, and clean and reliable cutting.

The present invention provides energy saving in half cut,
It is an object of the present invention to provide a half-cut device capable of reducing the size of a tape printing device structure and performing clean and reliable cutting, and a tape printing device including the same.

[0005]

A half-cutting device according to the present invention is a half-cutting mechanism for half-cutting a tape-like member introduced between the tape-receiving member and the tape-like member in a width direction thereof, and comprises a bevel blade. A half cutter having a cutter blade and moving in the width direction with respect to the tape-shaped member to perform a cutting operation; and a cutting preparation operation for causing the half cutter to advance toward the tape receiving member from a cutting standby position to a cutting start position. A circulating motion comprising: a cutting operation for moving from the cutting start position to the cutting completion position; a separating operation for retracting from the cutting completed position to the separating position; and a return operation for returning from the separating operation to the cutting standby position. And a cutter operating mechanism for performing the following.

According to this configuration, the half-cut means is
The cutting operation is performed by moving in the width direction of the tape-shaped member. That is,
Since the cutting is performed by the slide operation, the cutting can be performed with an extremely weak force as compared with the push-off method, so that energy saving, downsizing of the tape printing apparatus structure, and clean and reliable cutting can be performed. In addition, since the half cutter is separated from the receiving member at times other than the cutting operation, it does not hinder print feeding of the tape-shaped member or mounting work of the tape-shaped member between the half-cut and the receiving member.

In this case, the cutting operation is a linear operation in a direction orthogonal to the extending direction of the tape-shaped member.
preferable.

According to this configuration, the cutting operation is a linear operation in a direction orthogonal to the extending direction of the tape-shaped member, so that the cutting distance is shortest. Therefore, efficient and reliable cutting operation can be performed.

In these cases, the tape-shaped member is removably attached to the main body of the apparatus such that the leading end is inserted between the tape receiving member and the half-cutter from above, and the cutting operation of the half-cutter is performed in the downward direction. It is preferably done by moving from side to top.

According to this configuration, the cutting operation of the half cutter is performed by moving from the lower side to the upper side. The tape-shaped member has a feature that it is shifted upward during printing (because the upper portion between the platen roller and the print head is open), but in this case, when cut from top to bottom, the printing position of the tape-shaped member is shifted. Although there is a possibility that the tape is cut from the bottom to the top, the tape-shaped member is already close to the upper plate of the cartridge case or the like, so that there is no shift.

In these cases, the cutter operating mechanism includes a slide mechanism for causing the half cutter to perform a cutting operation and a return operation, a detachment mechanism for causing the half cutter to perform a cutting preparation operation and a detachment operation, a slide mechanism and a detachment and connection operation. It is preferable to have a power transmission mechanism for branching and transmitting power to the mechanism, and interlocking the slide mechanism and the separation / separation mechanism.

[0012] According to this configuration, since the power transmission mechanism for branching and interlocking the power with the slide mechanism and the separation / separation mechanism is provided, a complicated circulation motion can be performed with a simple structure. Further, since the slide mechanism and the separation / separation mechanism are linked, it is possible to accurately synchronize the operations.

In these cases, the slide mechanism is provided in parallel with the tape receiving surface of the tape receiving member, the guide shaft slidably supporting the half cutter, the half cutter connected to the distal end and the base end. And an input arm which is configured to be swingable around the center, swings by inputting power from a power transmission mechanism, and guides and slides the half cutter on a guide shaft.

In these cases, the separation / contact mechanism supports the guide shaft and is attached to the apparatus frame so as to be able to move forward and backward. One end is connected to the support block and the other end is connected to the apparatus frame. And an input plate that is rotatably mounted on the power transmission mechanism, receives power from a power transmission mechanism, rotates, and separates and moves the guide shaft via a support block.

In these cases, the power transmission mechanism includes a rotating disk that rotates by the power input from the drive source, a crank protrusion protruding from one end surface of the rotating disk, and the other end surface of the rotating disk. And a crank projection which circularly moves with the rotation of the rotary disk, engages with a crank slot formed in the input arm, and swings between the crank arm and the input arm. Preferably, the end face cam groove is engaged with a cam projection formed on the input plate to form an end face cam mechanism with the input plate.

According to this configuration, the rotational power of one rotary disk can be converted into the oscillating motion of the input arm and the input plate, and efficient power conversion can be achieved with a simple structure.

In these cases, it is desirable to cover the periphery of the slide area along the guide shaft of the half cutter with a cutter cover.

According to this configuration, since the periphery of the slide area along the guide shaft of the half cutter is covered with the cutter cover, invasion of foreign matter from the outside into the slide area can be prevented.

In these cases, it is preferable to provide a slit on the cutter cover so that the connecting portion between the half cutter and the input arm can slide along the guide shaft.

According to this configuration, the sliding operation of the half cutter is not hindered by the cutter cover.

In these cases, an entry preventing portion for preventing entry of the tape-shaped member into the slide area is formed on the tape receiving member side of the cutter cover.
preferable.

According to this structure, since the entry preventing portion for preventing the tape-shaped member from entering the slide area is formed, the slide cutting operation of the half cutter is not hindered by the jamming of the tape-shaped member.

In these cases, it is preferable that the cutter cover is formed with a cutter blade protection portion projecting toward the tape receiving member so as to overlap with the cutter blade of the half cutter at the cutting standby position.

According to this configuration, since the cutter blade is protected by the cutter blade protection portion at the cutting standby position,
It can protect against intrusion of foreign matter from outside.

In these cases, it is preferable that the tape receiving member is formed with a relief hole into which the tip of the cutter blade protection portion enters.

According to this configuration, the tape receiving member includes:
Since the escape hole into which the tip of the cutter blade protection portion enters is formed, it does not hinder the half cutter from approaching the tape receiving member.

The cutter holding portion 452 is formed by a bottom surface 453 that makes surface contact with one surface of the cutter blade 410, and a side wall surface 454 that surrounds a peripheral edge of the cutter blade 410.
At one corner of the side wall surface 454, there is a cutout 455 that allows the cutting edge 412 to protrude from the cutter holder 450.

The side wall surfaces 454 on both sides of the notch 455 are used as blade positioning portions 454a and 454b. Can be restricted. As described above, since the blade edge 411 and the regulating edge 413 are in solid contact with the blade positioning portions 454a and 454b, the protrusion amount of the cutter blade 410 from the cutter holder 450 can be constant regardless of the variation in the outer shape of the cutter blade 410. . The amount of protrusion of the cutting edge 412 can be adjusted by adjusting the size of the notch 455 between the blade positioning portions 454a and 454b.

The other two side wall surfaces 454 are provided with a suitable number of protrusions 456 protruding into the cutter holding portion 452. The cutter blade 410 has two edges 414, 4
15, the distal end side portion of the protruding portion 456 is pressed into the cutter holding portion 452 in a crushed state, and is fixedly held between each protruding portion 456 and the blade positioning portions 454 a and 454 b. An escape groove 456a is formed around the protruding portion 456 to allow the material of the crushed distal end portion to escape.

By the way, the cutter blade 410 cuts the entire width of the tape-like member 210, so that the tape-like member 210
The cutter blade 410 jumps in from the end face in the width direction of, and receives considerable damage at an early stage. In addition, intermittent cutting is repeated. Therefore, the cutter blade 410 has a risk of chipping or abrasion. However, as shown in FIG.
The above problem can be solved by setting the cut angle a, the bevel angle b, and the bevel angle c of 0 as follows.

That is, the cutter blade 410 held by the cutter holder 450 preferably has a cutting angle a of the cutting edge 411 with respect to 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 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 410 of the cutter blade 410 be sharp, but it is preferable that the cutting edge 412 be not less than 20 ° and not more than 50 °. 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.

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, the input plate 470 is provided with an end face cam groove 462 of the rotary disk 460 on one side of a substrate 471 having an outer shape such as a triangle.
, 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 each independently provided with the spring 48.
6a, 486b urges the tape receiving member 440 side and operates without being influenced by each other, so that the reliability of each function is improved.

Further, in the substrate 481 of the support block 480, a horizontally long mounting slot 487 is formed 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 member 440. In addition, the input plate mounting recess 4 that can be mounted so as to overlap the input plate 470 is provided 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 below the engaging recess 488a. 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 concave portion 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 contacted with the tape receiving member 440.

Therefore, the tape pressing member 420 can press the tape-shaped member 210 against the tape receiving member 440 and release the pressing. Also, the blade positioning member 430
The cutter blade 410 can be disposed at a cutting operation position at a predetermined distance from the tape receiving member 440 by bringing the cutter blade 410 into contact with the tape receiving member 440. At this time, since the pair of blade positioning members 430 abut at two locations above and below the tape receiving member 440, even when the structure such as the tape receiving member 440 is deformed or the like, the distance between the cutter blade 410 and the tape receiving member 440 is increased. The distance 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-like member 210 is uneven along the unevenness of the tape receiving surface 441 of the tape receiving member 440, and a cutting performance with a wide stable area can be obtained with respect to variations in the tape rigidity such as when the biting pressure of the cutter blade 410 is different.

Further, since the cutter blade 410 presses the tape-like member 210 against the tape receiving member 440 in a cantilever state, the deformation of the tape receiving member 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 provided with 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 portion 496, the rotation of the rotary 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.
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 rotates, the input plate 470 and the support block 48 are rotated as described above.
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 member 440, these separating and moving operations 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.
Is in a cutting standby position away from the lower end side.
Next, as shown in FIG. 10, the rotating disk 460 is rotated, and the support block 480 is moved through the input plate 470.
Is brought close to the tape receiving member 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 member 440. Also, the cutter blade 41
“0” is moved to the cutting start position close to the tape receiving member 440, and is positioned by the pair of blade positioning members 430 contacting the tape receiving member 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 member 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, since a complicated circulation cutting operation can be performed by the rotation force of one rotating disk 460, the operation can be efficiently performed by 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 has 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 member 440 (at a position facing the half-cutting means 400). It is configured so as to face the cutter blade 410 side. Then, the holding plate 403d formed on the cutter cover 403 described above,
The tape-shaped member 210 is nipped by a discharge sub-roller 514 disposed to face the discharge roller 510 to promote 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. 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 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 notch 443 of the tape receiving member 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

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-cut means 400, and controls one of the tape-shaped members 210 to be cut off by the full-cut 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 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 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, 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.

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.

Also, in the control flow, by 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 short, or when the power supply is cut off by pulling out 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, the cause of the stoppage of the cutter blade 410 can be specified, and the optimal return direction of the cutter blade 410 at the time of restarting can be determined. 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.

[0115]

As described above, according to the present invention, the half-cut means moves in the width direction of the tape-shaped member to perform the cutting operation. That is, since the cutting is performed by the slide operation, the cutting can be performed with an extremely weak force as compared with the pushing and cutting method, and energy saving, downsizing of the tape printing apparatus structure, and clean and reliable cutting can be performed.
