[0031]
The movable blade 32 will be further described. First, the movable blade 32 has a structure in which the cutting blade is detachable. That is, as shown in FIGS. 4 and 5, the movable blade 32 is configured by mounting the cutter holder 41 to which the cutting blade 32 a is mounted on the movable blade support 32 b provided continuously to the arm portion 33. .
[0032]
An engaging pin 44 for locking the cutter holder 41 protrudes from the movable blade support 32 b integrated with the arm portion 33.
[0033]
On the other hand, the cutter holder 41 has a storage groove 41a for mounting the cutting blade 32a therein, and the cutting blade 32a is stored so that the blade tip protrudes into the storage groove 41a. Holes 42 and 43 are formed in the cutter holder 41 and the cutting blade 32a accommodated therein. By engaging the engagement pins 44 of the movable blade support 32b with these holes 42 and 43, the cutter holder 41 is mounted on the movable blade support 32b.

Therefore, when the convex portions 47 and 48 abut on the cradle 31, a gap corresponding to the thickness of the peeling tape 6 b is formed between the movable blade 32 and the cradle 31. Only the printing tape 6a of the tape 6 can be cut (half cut).
[0036]
The cutting blade of the movable blade may be directly processed on the movable blade support 32b without being detachable.
[0037]
Next, the configuration of the drive mechanism 14 will be described.
[0038]
6 is a perspective view showing the configuration of the drive mechanism 14 of the cutting device 10, and FIG. 7 is an exploded perspective view showing the configuration of the torque limiter portion of the drive mechanism 14. As shown in FIG.
[0039]
As shown in FIG. 6, the drive mechanism 14 includes a transmission mechanism 51 for transmitting rotational drive in both forward and reverse directions of the cutter motor 13, a torque limiter 52 interposed in the transmission mechanism 51, and a movable blade moving mechanism. The cam 53 is used.
[0040]
The transmission mechanism 51 includes a plurality of large and small gears 61 to 68, and transmits the rotational drive of the cutter motor 13 in both forward and reverse directions. A torque limiter 52 is inserted in the transmission mechanism 51. As shown in the exploded perspective view of FIG. 7, the torque limiter 52 includes gears 62 and 63 and a coil spring interposed between them. By providing this torque limiter 52, idling occurs between the gear 62 and the gear 63 when a certain load or more is applied to the load side (cutting mechanism side). The torque limiter is not limited to that shown in the figure.
[0041]
The cam 53 is provided at the final end of the gear train of the transmission mechanism 51 and has a protrusion 54 on the rotation surface thereof. As shown in FIG. 3, when the cam 53 is rotated in response to the forward rotation drive of the cutter motor 13, the projection 54 is provided at the end of the arm portion 23 of the first cutting mechanism 11. The protrusion 25 is pressed to move the full-cut movable blade 22 to a position where it intersects the fixed blade 21. On the other hand, when the cam 53 is rotated by receiving the rotational drive in the reverse direction of the cutter motor 13, the projection 54 presses the operating pin 35 provided at the end of the arm portion 33 of the second cutting mechanism 12. Thus, the half-cut movable blade 32 is moved to a position where it abuts against the cradle 31.
[0042]
As shown in FIG. 3, a first sensor 71 and a second sensor 72 are installed on the chassis 2 a of the apparatus main body 2 so as to face the side surface of the cam 53. The first sensor 71 and the second sensor 72 are composed of microswitches, and are turned ON / OFF according to the rotation angle of the cam 53 during full cut and half cut. The side surface of the cam 53 has a concavo-convex shape for turning on / off the first sensor 71 and the second sensor 72 at a predetermined rotation angle.
[0043]
Here, the full cut realized by the first cutting mechanism 11 will be described.
[0044]
FIG. 8 is a diagram for explaining the operation of full cut by the first cutting mechanism 11. FIG. 8A is an initial state, FIG. 8B is during full cut, and FIG. 8C is full cut. Indicates the end status. In the state where the first cutting mechanism 11 is incorporated in the tape printer 1, the left side of the drawings is on the upper side.
[0045]
The full cut is to completely cut the tape. Here, the printing tape 6a, the peeling tape 6b, and the adhesive 6c of the laminated tape 6 shown in FIG. 2 are cut.
[0046]
As shown in FIG. 8A, in the initial state, the movable blade 22 is set to an initial position (home position) by a spring 26. At this time, the first sensor 71 is ON and the second sensor 72 is OFF.
[0047]
When the cutter motor 13 is driven to rotate forward from the initial state, the cam 53 rotates counterclockwise as shown in the figure, and accordingly, the projection 54 of the cam 53 moves on the arc orbit of the cam 53 and the end of the arm 23 is moved. It abuts against the operating projection 25 of the part. As a result, the arm portion 23 is pushed by the protrusion 54 and moves toward the fixed blade 21 against the force of the spring 26. When the cutter motor 13 further rotates in the forward direction, the movable blade 22 and the fixed blade 21 intersect, and the laminated tape 6 is fully cut.
[0048]
FIG. 8B shows a state during full cut. At this time, both the first sensor 71 and the second sensor 72 are OFF. FIG. 8C shows the end state of full cut. At this time, the first sensor 71 is OFF and the second sensor 72 is ON. When the cutter motor 13 rotates reversely after the end of the full cut, the movable blade 22 returns to the initial position shown in FIG.
[0049]
9A and 9B are diagrams for explaining the operation of half-cutting by the second cutting mechanism 12, in which FIG. 9A shows the initial state, and FIG. 9B shows the state during and after the half-cutting. In the state where the second cutting mechanism 12 is incorporated in the tape printer 1, the left side of the drawings is on the upper side.
[0050]
The half cut is to cut a part of the tape. Here, the print tape 6a and the adhesive 6c are cut while leaving the peeling tape 6b of the laminated tape 6 shown in FIG.
[0051]
As shown in FIG. 9 (a), in the initial state, the movable blade 32 is at the same position as the first cutting mechanism 11, and the movable blade 32 is set to the initial position (home position) by the force of the spring 37. At this time, the first sensor 71 is ON and the second sensor 72 is OFF.
[0052]
When the cutter motor 13 is driven to rotate in the reverse direction from the initial state, the cam 53 rotates in the clockwise direction in the drawing, and accordingly, the protrusion 54 of the cam 53 moves on the arc track of the cam 53, and the end of the arm portion 33. The operating pin 35 comes into contact. As a result, the arm 33 is pushed by the protrusion 54 and moves toward the cradle 31 against the force of the spring 37. When the cutter motor 13 is further reversely driven, the convex portions 47 and 48 of the cutter holder 41 abut on the receiving base 31. In this case, the tips of the projections 47 and 48 protrude from the cutting edge of the movable blade 32 by a dimension T corresponding to the thickness of the peeling tape 6 b, and a gap T is formed between the cradle 31 and the movable blade 32. Therefore, only the printing tape 6a and the adhesive 6c are cut leaving the peeling tape 6b. FIG. 9B shows a state during half-cutting. At this time, both the first sensor 71 and the second sensor 72 are turned on.
[0053]
Further, in order to sufficiently press the cutting edge of the movable blade 32 against the laminated tape 6, the cutter motor 13 is further driven in reverse in the state of FIG. 9B. At that time, a torque limiter 52 is inserted in the transmission mechanism 51 that transmits the rotational drive of the cutter motor 13 in order to prevent the torque of the cutter motor 13 from being over a certain level (see FIGS. 6 and 7). When the cutter motor 13 is driven in reverse for n seconds, the half cut for the laminated tape 6 is completed. At the end of the half cut, the state is the same as in FIG. After the half cut is completed, the cutter motor 13 rotates forward, and the movable blade 22 returns to the initial position shown in FIG.
[0054]
FIG. 10 is a block diagram showing a configuration of an electronic circuit of the tape printer 1 on which the cutting device 10 having the above-described configuration is mounted.
[0055]
The electronic circuit of the tape printer 1 is provided with a control unit 81 composed of a CPU. The control unit (CPU) 81 activates a system program stored in advance in the ROM 82 in response to a key operation signal from the input unit 3, and controls the operation of each circuit unit using the RAM 83 as a work memory. The control unit (CPU) 81 is connected to the input unit 3, ROM 82, and RAM 83, a display character generator (display CG) 84 that stores font pattern data for display, and a font for printing. A printing character generator (printing CG) 85 for storing the pattern data is connected.
[0056]
The ROM 82 stores in advance a system program that controls the entire operation of the tape printer 1 and also controls character string data input processing, display processing, text data printing processing including input character string data, and the like. Various subprograms are stored in advance. The RAM 83 stores various types of information necessary for processing by the control unit (CPU) 81.
[0057]
In addition, the control unit (CPU) 81 generates a display drive circuit 86 for displaying input character string data, information about printing, and the like on the display unit 4 and a heating element of the thermal head 8 according to the printing data. A head driving circuit 87 for driving, a step motor driving circuit 89 for a step motor 88 for rotationally driving the rotating shaft of the platen roller 9, and a cutter motor driving circuit 90 for driving the cutter motor 13 of the cutting device 10 are connected. .
[0058]
The cutter motor 13 is a DC motor, is a drive source of the cutting device 10, and is driven in both forward and reverse directions by a cutter motor drive circuit 90 under the control of a control unit (CPU) 81. The drive mechanism 14 transmits the rotational drive in both forward and reverse directions of the cutter motor 13 to drive the first cutting mechanism 11 and the second cutting mechanism 12, and here the cutter motor 13 rotates in the forward direction. When driven, the first cutting mechanism 11 is driven, and when the cutter motor 13 is driven to rotate in the reverse direction, the second cutting mechanism 12 is driven.
[0059]
Further, the initial position, the full cut end position, and the half cut end position of the first cutting mechanism 11 and the second cutting mechanism 12 are detected according to the rotation angle of the cam 53 provided in the drive mechanism 14. A first sensor 71 and a second sensor 72 are provided.
[0060]
Here, prior to describing the printing operation by the tape printer 1, the positional relationship with the cutting device 10 mounted on the tape printer 1 will be described.
[0061]
FIG. 11 is a diagram showing the relationship between the head position, the full cut position, and the half cut position. FIG. 12 shows an example of tape printing and a cross-sectional view thereof.
[0062]
In FIG. 11, H is the position of the thermal head 8 of the tape printer 1, c 1 is the full cut position by the first cutting mechanism 11 of the cutting apparatus 10, and c 2 is the half cut position by the second cutting mechanism 12 of the cutting apparatus 10. These are located in order toward the downstream side in the tape transport direction. The interval between the position H of the thermal head 8 and the full cut position c1 is a, and the interval between the full cut position c1 and the half cut position c2 is b.
[0063]
Also, as shown in FIG. 12, the margin length set before and after the character string to be printed on the print tape 6a of the laminated tape 6 by the thermal head 8 is the interval between the position H of the thermal head 8 and the full cut position c1. It is assumed that a is a half cut at a distance c from the end of the laminated tape 6. A printing tape 6a and a release tape 6b are laminated on the laminated tape 6 with an adhesive 6c, and a half cut is made in the portion of the laminated tape 6 where the printing tape 6a is provided. For example, a = 20 mm, b = 5 mm, and c = 10 mm.
[0064]
Below, the printing operation by the tape printer 1 is demonstrated.
[0065]
FIG. 13 is a flowchart showing the operation of the initial processing by the tape printer 1.
[0066]
When the power switch of the tape printer 1 is turned on, first, it is checked whether the first cutting mechanism 11 and the second cutting mechanism 12 of the cutting device 10 mounted on the tape printer 1 are in the initial position. Is done. In this case, the initial positions of the first cutting mechanism 11 and the second cutting mechanism 12 are the same, and this initial position is obtained by detecting the rotation angle of the cam 53 by the first sensor 71 and the second sensor 72. Done.
[0067]
That is, when the first sensor 71 is ON and the second sensor 72 is OFF (Yes in step S1), the first cutting mechanism 11 and the second cutting mechanism 12 are shown in FIG. It is determined that the current position is at the initial position shown in FIG. 9A, and an initial input screen is displayed on the display unit 4 (step S9).
[0068]
On the other hand, when both the first sensor 71 and the second sensor 72 are ON (Yes in step S2), the movable blade 32 for half cut that constitutes the second cutting mechanism 12 is shown in FIG. In this case, the cutter motor 13 is driven to rotate forward until the first sensor 71 is turned on and the second sensor 72 is turned off. Processing such as returning to the initial position is performed (steps S3 to S5). Further, when the first sensor 71 is OFF and the second sensor 72 is ON (No in step S2), the full-cut movable blade 22 constituting the first cutting mechanism 12 is shown in FIG. c), and in this case, the cutter motor 13 is driven reversely until the first sensor 71 is turned on and the second sensor 72 is turned off, so that the movable blade 22 is initialized. Processing such as returning to the position is performed (steps S6 to S8).
[0069]
FIG. 14 is a flowchart showing the operation of the printing process by the tape printer 1. FIG. 14 (a) shows the overall flow of the printing process, FIG. 14 (b) shows the half cut process, and FIG. 14 (c) shows the full process. The process at the time of cutting is shown.
[0070]
When the first cutting mechanism 11 and the second cutting mechanism 12 of the cutting apparatus 10 are set to the initial positions by the initial processing of FIG. 13, the printing of the character string input from the input unit 3 is instructed. The following printing process is executed by the control unit (CPU) 81. At this time, the laminated tape 6 is set between the thermal head 8 and the platen roller 9, and the front end of the laminated tape 6 is at the full cut position c1 shown in FIG.
[0071]
As shown in FIG. 14A, when printing of a character string is instructed, the platen roller 9 rotates and the laminated tape 6 is conveyed toward the paper discharge port 7 (step A1). When the laminated tape 6 is conveyed by the distance c shown in FIG. 12 (Yes in Step A2), the thermal head 8 is driven and printing of a character string for one line on the laminated tape 6 is started (Step S2). A3). In this case, since the distance between the head position H and the full cut position c1 is a as shown in FIG. 11, printing is performed after the margin of c + a from the end of the laminated tape 6 as shown in FIG. Become.
[0072]
Here, after the start of printing, when the laminated tape 6 is conveyed toward the paper discharge port 7 by c + b (steps A4 and A5), the printing process and the tape conveying process are temporarily interrupted (step A6). By driving the second cutting mechanism 12, a half cut process is performed on the laminated tape 6 (step A7). Thereby, as shown in FIG. 12, a half cut is formed at a distance c from the tip of the laminated tape 6. At the same time, a margin of length a is created before the character string to be printed.
[0073]
At the time of half-cutting, as shown in FIG. 14B, the cutter motor 13 is driven in reverse (step B1). As described with reference to FIG. 9, the half-cut movable blade 32 constituting the second cutting mechanism 12 moves from the initial position toward the cradle 31 by the reverse rotation driving of the cutter motor 13. The movable blade 32 cuts into the laminated tape 6 with a gap T shown in FIG. 4 in a state where the convex portions 47 and 48 of the cutter holder 41 that supports the movable blade 32 are in contact with the receiving base 31. Only the printing tape 6a of the laminated tape 6 is cut.
[0074]
In this case, the reverse rotation driving of the cutter motor 13 is set to n seconds. This n seconds is set longer than the time until the convex portions 47 and 48 of the cutter holder 41 abut on the receiving base 31. Therefore, after the convex portions 47 and 48 of the cutter holder 41 abut on the cradle 31, the movable blade 32 is pressed against the printing tape 6a of the laminated tape 6 for the remaining time of n seconds. Thereby, it can cut | disconnect reliably and can make a half cut neatly. In addition, a torque limiter 52 is interposed in the transmission mechanism 51 that transmits the rotational drive of the cutter motor 13 in order to prevent a torque exceeding a certain level from being applied to the cutter motor 13 at that time.
[0075]
When the n seconds elapse (Yes in step B2), the cutter motor 13 is driven to rotate forward until the first sensor 71 is turned on and the second sensor 72 is turned off (steps B3 and B4). Thereby, the movable blade 32 for half cut returns to the original initial position.
[0076]
After such a half-cut process, as shown in FIG. 14A, the printing process and the tape transport process are resumed (steps A8 and A9). When the printing of the designated character string is completed (Yes in Step A10), the laminated tape 6 is conveyed by a distance of 2a (Steps A11 and A12), and the first cutting mechanism 11 of the cutting device 10 is driven, A full cut process is performed on the laminated tape 6 (step A13). As a result, as shown in FIG. 12, the printed laminated tape 6 is completely cut off and discharged out of the apparatus from the paper discharge port 7, and a blank space a is formed after the character string of the laminated tape 6.
[0077]
At the time of the full cut, as shown in FIG. 14C, the cutter motor 13 is driven forward (step C1). By the normal rotation driving of the cutter motor 13, as described with reference to FIG. 8, the full-cut movable blade 22 constituting the first cutting mechanism 11 moves from the initial position toward the fixed blade 21. When the cutter motor 13 is driven to rotate forward until the first sensor 71 is turned off and the second sensor 72 is turned on (step C2), the movable blade 22 and the fixed blade 21 intersect, and the entire laminated tape 6 is crossed. Is cut and the printed tape portion is separated as a label.
[0078]
After the end of the full cut, the cutter motor 13 is driven to rotate forward until the first sensor 71 is turned on and the second sensor 72 is turned off (steps C3 and C4). Thereby, the movable blade 22 returns to the original initial position.
[0079]
Since the label created by such a printing process is cut by half-cut processing at the end of the printing tape 6a of the laminated tape 6, the printing tape 6a can be easily peeled off from the peeling tape 6b. For example, it can be used as a sticky note.
[0080]
The cutting device 10 mounted on the tape printer 1 includes a first cutting mechanism 11 and a second cutting mechanism 12, and these are commonly driven by a single cutter motor 13 and a driving mechanism 14. Since the structure is such that the structure of the cutting device itself can be reduced in size, the overall configuration of the tape printer can also be simplified and the size can be reduced.
[0081]
Furthermore, at the time of half-cutting, the movable blade 32 for half-cutting that constitutes the second cutting mechanism 12 is moved toward the receiving base 31, and a part of the laminated tape 6 is cut by pressing the movable blade 32. In this case, since the cutter motor 13 is driven and controlled so that the movable blade 32 is held on the cradle 31 for a predetermined time, a part of the laminated tape 6 can be cut reliably. Further, even if a certain torque or more is applied to the cutter motor 13 at that time, the cutter motor 13 is not damaged because the cutter motor 13 is idled by the torque limiter 52 inserted in the transmission mechanism 51.
[0082]
The torque limiter 52 is not necessarily provided. In that case, it is desirable to use a lock motor that can handle the output shaft as the cutter motor 13.
[0083]
Moreover, although the said embodiment demonstrated the case where the laminated tape for printing used for a printing apparatus was cut | disconnected, this invention is not limited to the laminated tape used for a printing apparatus, 1st layer and 2nd layer Can be applied to all of the laminated members.
[0084]
Moreover, in the said embodiment, although the laminated tape which used the 1st layer as the printing tape and the 2nd layer as the peeling tape was used, the reverse structure, ie, the 1st layer as the peeling tape, and the 2nd layer as the printing tape. A laminated tape may be used.
[0085]
【The invention's effect】
As described above in detail, according to the present invention, in the cutting apparatus provided with the first cutting mechanism and the second cutting mechanism, the first cutting mechanism and the second cutting mechanism using the drive source and the driving mechanism common to them. Since the mechanism is driven to cut all layers and some layers of the laminated member, the size of the cutting device can be reduced by sharing the drive source and the drive mechanism.
[0086]
Also, the cutting blade Install the cutter holder A part of the laminated member is cut by contacting the cradle. When , That cutter holder To the cradle Predetermined contact state Time Certainty By controlling the drive source to keep Some layers of the laminated member It can be cut reliably.
