Abstract

PURPOSE:To cut a member into the desired length and width respectively by installing a first cutter, cutting the cut member conveyed by conveyor means in a direction orthogonal with the conveying direction, and a second cutter, cutting the cut member in a direction parallel with the conveying direction, respectively. CONSTITUTION:Since separate paper 7 is not cut off, a printed tape 4 is conveyed in a state of being kept intact, and information is printed on a pressure sensitive adhesive tape 6 and this tape is fed to an interval between a first cutter 11 and a cradle 12. When the printed tape 4 printed with the information is fed as long as the desired length, each rotation of a platen roller 1 and an ink tape take-up reel P by a motor is stopped, and the printed tape 4 is cut into the desired length by the first cutter 11. In consequence, the printed tape 4 being printed with the specified information and cut into the desired length is thus securable. In this printed tape 4, only the pressure-sensitive adhesive tape 6 is cut off by a second cutter for half cut use.

A thermal print head 3 is arranged in the vicinity of the lower side of the platen roller 1 so as to be able to come into contact with and separate from the platen roller 1. On the right side of the platen roller 1 and the thermal print head 3, a print-receiving tape supply reel 5 around which a print-receiving tape (member to be cut) 4 is wound in a roll is rotatably arranged. As shown in FIG. 2, the print-receiving tape 4 is formed by adhering a release paper 7 to an adhesive tape 6, and the tip side thereof is arranged between the platen roller 1 and the thermal print head 3, and the thermal print head 3 causes the platen to move. The platen roller 1 is conveyed while being pressed against the roller 1. An ink tape supply reel 8 and an ink tape take-up reel 9 are rotatably provided below the thermal print head 3. The ink tape take-up reel 9 is driven by a motor (not shown) to take up the ink tape 10 wound on the ink tape supply reel 8 between the platen roller 1 and the thermal print head 3. The print-receiving tape 4 and the ink tape 10 are
Between the platen roller 1 and the thermal print head 3, the surface of the adhesive tape 6 and the ink surface of the ink tape 10 are in contact with each other and are superposed on each other.

On the other hand, on the left side of the platen roller 1 and the thermal print head 3, the first cutting blade 11 is perpendicular to the direction in which the print-receiving tape 4 is conveyed and perpendicular to the print-receiving tape 4. It is arranged so that it can reciprocate. A pedestal 12 is provided on the front end side of the first cutting blade 11 so as to sandwich the print-receiving tape 4. Also, the thermal print head 3
On the lower side of the print-receiving tape 4 between the print-receiving tape supply reel 5 and the print-receiving tape supply reel 5, that is, on the adhesive tape 6 side, a support base 13 is rotatably arranged around a shaft portion 14 provided at a right end portion of a side surface thereof. Has been done. The support base 13 is formed in a substantially plate shape as shown in FIG. 3, and three half-cutting second cutting blades 15 are arranged on the upper surface of the support base 13 at equal intervals in parallel with the transport direction of the print-receiving tape 4. Has been done. The cutting edge of the second cutting blade 15 for half-cutting is formed so that it is higher on the thermal print head 3 side and gradually lowers toward the print-receiving tape supply reel 5 side, and cuts only the adhesive tape 6 of the print-receiving tape 4. It has a structure. A pressure contact roller 16 is rotatably arranged at a position facing the second cutting blade 15 with the print-receiving tape 4 interposed therebetween. The shaft portion 1 of the support base 13
4 is provided with a torsion spring 17. The torsion spring 17 has one end attached to the side surface of the support base 13 and the other end abutting a pin 18 on the device body side to urge the support base 13 toward the print-receiving tape 4 side, and the second cutting blade. 15 is pressed against the print-receiving tape 4 so that it is cut into only the adhesive tape 6.

Next, the operation of such a cutting device will be described. The print-receiving tape 4 drawn out from the print-receiving tape supply reel 5 in advance is attached to the second cutting blade 15 and the pressure roller 1.

The adhesive tape 6 is arranged between the platen roller 1 and the thermal print head 3 so as to come into contact with and overlap with the surface of the adhesive tape 6.

Then, when the motor drives the platen roller 1 and the ink tape take-up reel 9 to rotate while the thermal print head 3 presses the ink tape 10 and the print-receiving tape 4 against the platen roller 1, the thermal print head is rotated. While the ink of the ink tape 10 is transferred to the surface of the adhesive tape 6 by 3 and the predetermined information is printed, the print-receiving tape 4 and the ink tape 10 are conveyed, whereby the print-receiving tape 4 becomes the first cutting blade 11 and The ink tape 10 is sent out between the pedestals 12 and wound on the ink tape take-up reel 9.

When the print-receiving tape 4 on which the information is printed in this manner is sent out, the second cutting blade 15 of the support 13 presses the print-receiving tape 4 against the pressure contact roller 16 by the urging force of the torsion spring 17. Printed tape 4
Is conveyed, the three half-cutting second cutting blades 15 cut only the adhesive tape 6 into four equal parts in the width direction in parallel with the conveying direction as shown in FIG. However, since the release paper 7 is not cut, the print-receiving tape 4 is conveyed as it is, the information is printed on the adhesive tape 6 as described above, and the gap between the first cutting blade 11 and the pedestal 12 is increased. Sent to. Then, when the print-receiving tape 4 on which the information is printed is fed to a desired length, the rotation of the platen roller 1 and the ink tape take-up reel 9 by the motor is stopped, and the print-receiving tape 4 is moved to the desired length by the first cutting blade 11. Cut into pieces.

As a result, as shown in FIG. 4, it is possible to obtain the print-receiving tape 4 in which predetermined information is printed and cut into a desired length. Since only the adhesive tape 6 is cut by the second cutting blade 15 for half-cutting, the print-receiving tape 4 can be used by separating only the necessary portion from the release paper 7. Therefore, it is not necessary to cut the print-receiving tape 4 cut into a desired length with the first cutting blade 11 into a desired width with a knife or scissors as in the conventional case.
Very easy to use.

In the embodiment described above, the second cutting blade 1
5 is formed on a half-cut blade that cuts only the adhesive tape 6, but not limited to this, for example, as shown in FIG. 5, two pieces for full cut for cutting both the adhesive tape 6 and the release paper 7. The second cutting blade 20 may be provided on the upper surface of the support base 13. In this case, the cutting edge of the second cutting blade 20 may be formed larger than the second cutting blade 15 described above, or the spring force of the torsion spring 17 may be increased.

In the above-described embodiment, the print-receiving tape 4 is conveyed by the rotation of the platen roller 1 while the print-receiving tape 4 is pressed against the platen roller 1 by the thermal print head 3. A roller may be provided to convey the print-receiving tape 4.

Further, in the above-described embodiment, the print-receiving tape 4 in which the release paper 7 is attached to the adhesive tape 6 is used as the member to be cut, but the invention is not limited to this, and heat-sensitive paper or ordinary print paper may be used. You may use.
