In FIG. 1A, the frame 18 that supports the entire cutting apparatus is indicated by a solid line, and the printed tape 19 is indicated by a two-dot chain line. However, FIG. The illustration of the frame 18 and the printed tape 19 is omitted for the sake of illustration.
[0018]
As shown in FIGS. 1A and 1B, the cutting device 20 first includes a moving member 22 having a window 21. The moving member 22 is provided with a pin 23 protruding forward and forward (in the depth direction of the drawing in FIG. 2B) at a substantially central portion of the right end of the figure, and a pin 24 protruding rearward coaxially with the pin. And a horizontally elongated rectangular boss 25 (see FIG. 3A) which is engaged with the pin 24. The rectangular boss 25 is slidably fitted in a horizontally long groove that cannot be clearly seen in the drawing of the frame 18, whereby the moving member 22 moves in the first direction (as shown by a double-headed arrow B in the drawing). In this example, it is configured to be movable in a left direction of the figure) and in a second direction opposite to the first direction (that is, in the right direction of the figure).
[0019]
The window 21 of the moving member 22 has a large divergent V-shaped movable shearing blade 26 formed at the edge in the first direction, and a window surface at the edge in the second direction. Is formed at a right angle.
In the first direction (left side in the figure) of the moving member 22, push-off portions provided at both ends with abutting portions 28 a and 28 b projecting in the direction of the holding portion 27 at positions opposed to the holding portion 27. A blade 29 is fixedly arranged on the frame 18. The push cutting blade 29 is formed with a blade portion 31 having a predetermined step from the protruding ends of the abutting portions 28a and 28b. When the moving member 22 moves in the first direction, the press cutting blade 29 is pressed to the left by the pressing portion 27 via the abutting portions 28a and 28b that come into contact with the pressing portion 27.
[0020]
A fixed shearing blade 32 is fixed to the frame 18 in contact with the moving member 22 on the opposite side of the moving blade 22 from the pushing blade 29. When the movable member 22 moves in the second direction (to the right in the drawing), the fixed shear blade 32 is disposed at a position where the movable shear blade 26 can be in sliding contact with the movable shear blade 26.
[0021]
A vertically long hole 34 of the rotating member 33 is slidably engaged with the above-described pin 23 at the substantially right end of the moving member 22. The slot 34 and the pin 23 are engaged substantially at the center of the slot 34 at the reference position shown in FIG.
[0022]
The rotating member 33 is supported at its upper end by a support shaft 35, and is configured to be rotatable left and right with the support shaft 35 as a fulcrum as shown by a double-headed arrow C in the figure. The long hole 34 is formed substantially at the center of the rotating member 33 at a position near the moving member 22. A vertically long hole 36 is also formed at the end of the rotating member 33 opposite to the long hole 34, that is, at the lower end of the right end in the figure. The pin 38 of the member 37 is slidably fitted.
[0023]
The pin 38 is provided at a position shifted outward from the center of the rotating member 37. When the entire apparatus is at the reference position shown in FIG. And is located at a substantially lower end portion of the long hole 36.
The rotating member 37 has a step formed at two places along the rotating peripheral surface to form a cam. Two switches 39a and 39b are arranged in contact with the peripheral surface of the cam. The two switches 39a and 39b are turned on and off when one (or the other) switch pin is pushed into and pushed into the convex portion of the cam portion, which is the rotating peripheral surface of the rotating member 37. When the switch is open (off) with the other (or one) switch pin facing the concave portion of the cam portion, there are two states, and both switch pins ride on the convex portion of the cam portion. When the switch is closed by being pushed in, and when the switch is open with both switch pins facing the concave portion of the cam portion, there are two states of the rotary member 37 in total. The rotational position can be detected.
[0024]
2 and 3 are diagrams for explaining the operation state of the cutting device 20. FIG. Both figures show a top view at the top and a front view at the bottom. Also in these figures, the top view shows the frame 18 for supporting the entire cutting apparatus by solid lines, the printed tape 19 is shown by a two-dot chain line, and the front views show the frame 18 and the printed tape 19. Are not shown.
[0025]
Hereinafter, the operation of the cutting apparatus 20 will be described with reference to FIGS. A drive motor for rotating the rotating member 37 in both forward and reverse directions is not shown. Further, a control device for detecting the ON / OFF state of the switches 39a and 39b and controlling the rotation of the drive motor is not shown.
[0026]
First, as shown in FIG. 1, in the standby state, the switches 39a and 39b are in the [ON, OFF] state. Here, the rotating member 37 is rotated clockwise. Thus, the pin 38 of the rotating member 37 moves diagonally upward and to the left while sliding on the long hole 36 of the rotating member 33. The switches 39a and 39b change to [ON, ON] and [OFF, ON], and stop the rotation of the rotating member 37 when the switches 39a and 39b enter the [OFF, OFF] state as shown in FIG.
[0027]
As a result, the rotating member 33 is pushed leftward by the pin 38 of the rotating member 37 through its own elongated hole 36, and rotates leftward with the support shaft 35 as a fulcrum. Further, thereby, the moving member 22 is pushed to the left by the long hole 34 of the rotating member 33 via its own pin 23, and the pressing portion 27 is moved to the butting portions 28 a and 28 b of the pressing blade 29. It is pushed in the direction of the blade part 31 until it hits.
[0028]
As a result, the printed tape 19 that has been inserted through the window 21 of the moving member 22 is driven into the step between the butting portions 28 a and 28 b of the pressing blade 29 and the blade 31. The depth (height) of the step portion between the abutting portions 28a and 28b of the push cutting blade 29 and the blade portion 31 is the thickness on the side of the partial cut surface 19a to be partially cut from the entire thickness of the printed tape 19. It is formed corresponding to the thickness except for the thickness.
[0029]
In other words, the printed tape 19 is formed to be thicker than the depth of the step by the thickness of the partially cut surface 19a.
Accordingly, as described above, the pressing portion 27 moves toward the blade portion 31 until the pressing portion 27 abuts against the abutting portions 28a and 28b of the pressing blade 29, and the printed tape 19 is pushed toward the blade portion 31. The printed tape 19, which is formed thicker by the thickness of the partial cut surface 19a than the depth of the partial cut surface 19a, is further pushed in the direction of the blade portion 31 by the thickness on the side of the partial cut surface 19a, and is partially cut into contact with the blade portion 31. The cut surface 19a is cut by the blade portion 31. That is, the partial cutting of the printed tape 19 is completed.
[0030]
The partially cut surface 19a of the printed tape 19 is, for example, a printing tape portion with an adhesive, and the non-partially cut surface 19b is, for example, release paper. Of course, the reverse configuration may be adopted.
Returning from this state to the standby state of FIG. 1, the partially cut printed tape 19 is further pushed out to the window portion 21 to the cutoff position. Here, the rotating member 37 is rotated counterclockwise. As a result, the pin 38 of the rotating member 37 moves obliquely upward to the right while sliding on the long hole 36 of the rotating member 33. The switches 39a and 39b change to [ON, OFF] and [OFF, OFF], and when the switches 39a and 39b enter the [OFF, ON] state as shown in FIG. 3, the rotation member 37 is stopped.
[0031]
As a result, the rotating member 33 is pulled out to the right by the pin 38 of the rotating member 37 through the self-elongated hole 36, and rotates rightward with the support shaft 35 as a fulcrum. Further, thereby, the moving member 22 is pulled out to the right by the long hole 34 of the rotating member 33 via the own pin 23, and the movable shear blade 26 comes into sliding contact with the fixed shear blade 32.
[0032]
As a result, the shearing of the printed tape 19 inserted through the window 21 of the moving member 22 by the movable shear blade 26 and the fixed shear blade 32 is performed at both ends of the movable shear blade 26 formed with a V-shaped slope. Starting from both sides, ie, from both ends in the width direction of the printed tape 19 and converging to the center, the printed tape 19 is cut at a predetermined separation position.
[0033]
On one surface of the printed tape 19 after separation, a cut by partial cutting is formed near the end, and this portion is bent to easily peel off the release paper and the adhesive-attached printing tape. be able to.
In the above embodiment, the cutting of the printed tape of the tape printer has been described as an example. However, the present invention is not limited to this, and the cutting apparatus according to the present invention needs to perform both partial cutting and full cutting. The present invention can be applied to any cut member having a certain shape.
[0034]
【The invention's effect】
As described above, according to the present invention, both the partial cutting of the member to be cut in the thickness direction to a predetermined position and the entire cutting and cutting are performed by one drive mechanism. It contributes to reduction of manufacturing cost and miniaturization of equipment.
[0035]
Also, since only one rotating mechanism is used, this also contributes to reduction of manufacturing cost and downsizing of the apparatus.
