【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

1 and 2 show the main part of the printing apparatus. In this printing apparatus, a chassis 2 is provided inside a portable box-shaped apparatus main body 1, a tape cassette 3 is removably mounted on the upper surface of the chassis 2, and the mounted tape cassette 3 is mounted. It is adapted to be covered by a lid 4 which is openably and closably attached to the main body 1. In this case, a sheet key 6 for inputting information and a liquid crystal display section 7 for displaying the input information are provided on the surface of the lid 4, as shown in FIG. Although not shown, the printing device can be connected to external devices such as an electronic notebook and a word processor via a communication cable.

A winding shaft 10, a platen roller 11, and a thermal print head 12 are provided at predetermined positions in the apparatus main body 1 so as to project above the chassis 2. The winding shaft 10 is rotatably provided on the apparatus main body 1. The platen roller 11 is rotatably provided on a support plate 13 provided on the apparatus body 1. The thermal print head 12 is provided at the location of the apparatus main body 1 so as to be able to come into contact with and separate from the platen roller 11. The thermal print head 12 is in the form of a vertically long and slender plate, and a large number of heating elements (not shown) are arranged in the vertical direction at fine intervals. In addition, a printing tape discharge port 14 and a cutting device 30 described later are provided at predetermined positions on the upper left wall of the device body 1.

In the tape cassette 3 mounted on the chassis 2, the print-receiving tape supply reel 15 is fitted to the cassette guide shaft 16 and the ink tape take-up reel 17 is engaged to the take-up shaft 10. It is mounted at a predetermined location on the chassis 2. In this state, the adhesive tape (cut object) 18 to be printed, which is fed from the print tape supply reel 15, is passed between the platen roller 11 and the thermal print head 12, and through the print tape discharge port 14 to the apparatus main body 1 Sent out of. The ink tape 20 fed from the ink tape supply reel 19 is wound around the ink tape take-up reel 17 between the platen roller 11 and the thermal print head 12 and via the ink tape guide pin 21. In this case, the adhesive tape 18 is formed by laminating a release paper 18c on a base tape 18a via an adhesive layer 18b as shown in FIG. Further, the adhesive tape 18 and the ink tape 20 between the platen roller 11 and the thermal print head 12 are overlapped with each other in a state where the surface of the base tape 18a of the adhesive tape 18 and the ink of the ink tape 20 are in contact with each other. Is becoming.

On the other hand, the cutting device 30 is provided in the vicinity of the printing tape discharge port 14 of the apparatus main body 1 and cuts the adhesive tape 18 fed from the printing tape discharge port 14 and performs a half cut. 3 (A) to FIG. 3 (C). That is, the first operation member 31 for full cut is slidably arranged toward the inside of the side wall of the device main body 1 toward the print tape discharge port 14, and the second half cut member is arranged on the outer side thereof. The operation member 41 is similarly arranged.

The first operation member 31 has a button portion 32 protruding outward from a long hole 33 of the device body 1 at an end portion (a lower end portion in FIG. 3A) opposite to the print tape discharge port 14. When the button portion 32 is operated from outside the device body 1, the button portion 32 slides in the direction (arrows X and Y directions) in and out of the print tape discharge port 14. The first operating member 31 is always separated from the print tape discharge port 14 by the coil spring 34 provided between the tip (upper end in the figure) and the inner surface of the device body 1 facing the first operation member 31 (arrow Y). The button portion 32 is in contact with the edge of the long hole 33. A first cutting blade 35 for full cutting is attached to the tip of the first operating member 31 with the cutting edge 35 a facing the printing tape discharge port 14. The first cutting blade 35 moves together with the first operating member 31 so that the blade edge 35a appears and disappears in the print tape discharge port 14 to completely cut the adhesive tape 18 as shown in FIG. It has become.

The second operating member 41 is formed to be shorter than the length of the first operating member 31 by the length of the button portion 32, and the button portion 42 is provided at its end portion (lower end portion in the figure). It is provided so as to project from the long hole 33 of the device body 1 to the outside. The button portion 42 projects outward from the outer surface of the push button 32 of the first operating member 31 so that the second operating member 41 can be easily operated by itself. Further, the second operating member 41 is always urged in the arrow Y direction by the coil spring 44 provided between the tip of the second operating member 41 and the inner surface of the device body 1 facing the second operating member 41. The button portion 42 is in contact with the button portion 32 of the first operating member 31. Further, a second cutting blade 45 for half cutting is attached to the tip of the second operating member 41 in the same manner as the first cutting blade 35. Similar to the first cutting blade 35, the second cutting blade 45 has a cutting edge 45a that appears in and out of the printing tape discharge port 14, so that the base tape 18a (including the adhesive layer 18b) of the adhesive tape 18 is also included as shown in FIG. ) Is cut and the adhesive tape 18 is half-cut. That is, the cutting edge 45a of the second cutting blade 45 is slightly retracted from the cutting edge 35a of the first cutting blade 35 so as not to completely cut the adhesive tape 18 together with the release paper 18c. The difference is, for example, the thickness of the release paper 18c of the adhesive tape 18, or the thickness of the base tape 18a and the adhesive layer 18b.

Next, the operation of the cutting device 30 will be described with reference to FIGS. 3 to 5. In this case, desired information is sequentially printed on the surface of the base tape 18a of the adhesive tape 18 by the thermal printing head 12 of the printing device as shown in FIG. Sent to.

When the adhesive tape 18 is half-cut, only the button portion 42 of the second operation member 41 is pressed in the arrow X direction. Then, the second operating member 41 slides in the arrow X direction against the coil spring 44, the second cutting blade 45 moves in the same direction together with the second operating member 41, and the blade edge 45a of the second cutting blade 45 moves. The adhesive tape 18 is half-cut by being projected into the printing tape discharge port 14, and by the protruding cutting edge 45 a of the second cutting blade 45. That is, since the cutting edge 45a of the second cutting blade 45 is slightly retracted from the cutting edge 35a of the first cutting blade 35, the adhesive tape 18 is not completely cut together with the release paper 18c, and the second cutting blade 45 shown in FIG. Since only the base tape 18a of the adhesive tape 18 is cut as described above, the half cut Ch is applied to a predetermined portion of the adhesive tape 18. After that, the restoring force of the coil spring 44 causes the second operating member 41 to move in the direction of the arrow Y to return to the original initial position, and the button portion 42 contacts the button portion 32 of the first operating member 31.

In this way, when the half-cuts Ch are sequentially applied to predetermined portions of the adhesive tape 18 as shown in FIG. 5 and then the adhesive tape 18 is cut, the button of the first operation member 31 is pressed. The section 32 is operated. At this time, since the button portion 42 of the second operating member 41 is in contact with the button portion 32 of the first operating member 31, when the button portion 32 of the first operating member 31 is pressed in the arrow X direction, the coil spring 34 is pressed. The first operating member 31 slides in the direction of the arrow X 2 against the above, and the second operating member 41 also slides in the same direction against the coil spring 44. Therefore, both the first cutting blade 35 and the second cutting blade 45 project into the printing tape discharge port 14 at the same time. When the first and second cutting blades 35 and 45 project into the printing tape discharge port 14 in this manner, the cutting edge 35a of the first cutting blade 35 projects slightly from the cutting edge 45a of the second cutting blade 45. As shown in FIG. 4, the adhesive tape 18 is completely cut together with the release paper 18c, and the second cutting blade 45 makes a half cut Ch on the adhesive tape 18 in the vicinity of the cut portion Cf in the same manner as described above.

As described above, in the cutting device 30, it is possible to appropriately perform the half-cut Ch at the desired portion of the adhesive tape 18 while sequentially printing the desired information on the adhesive tape 18, so that at each of the half-cut Ch locations. The base tape 18a together with the adhesive layer 18b can be separated from the paper 18c by peeling it off, and the separated base tape 18a can be used as a label. Therefore, even when the adhesive tape 18 on which desired information is continuously printed is cut as in the conventional case and then the adhesive tape 18 is further cut into a plurality of pieces, it is not necessary to use scissors or a knife. The adhesive tape 18 having a desired size can be simply obtained.

The present invention is not limited to the above-described embodiment, and a print head such as a wire dot may be used instead of the thermal print head 12. Further, the print head is not limited to a label printing device, and printing of a data processing device such as a word processor. It can also be widely used in devices.

[Effect of the device]

 As described above, according to the present invention, only the second cutting blade is actuated by the first operating means to cut only the base material or the release paper of the object to be cut, so that an appropriate half cut is made to the object to be cut. It is possible to perform cutting, and the second operating means can actuate both the first and second cutting blades to completely cut the object to be cut, and at the same time, to perform half cutting on the object to be cut. Therefore, even after cutting the object to be cut, the base material or the release paper of the object to be cut can be appropriately separated easily at the half-cut location without using scissors or knife.
