Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device for cutting a continuous strip-shaped member to be cut such as an adhesive tape with release paper.

[0002]

2. Description of the Related Art In printers, handy type printers that can easily print desired information at desired places are widely used. As such a printing device, for example, desired information is printed on a printing target tape (cutting member) in which release paper is attached to an adhesive tape, and this printing target tape is cut to a desired length by a cutting device. There is a label printer that can be cut into pieces and used as labels.

A cutting device for cutting such a print-receiving tape completely cuts both the adhesive tape and the release paper of the print-receiving tape in order to easily separate the adhesive tape and the release paper after cutting. In addition to this, a half-cut blade that cuts only one of the adhesive tape or release paper is provided downward on one support base, and the print-receiving tape is placed between this support base and the receiving surface below it. By pressing down the support base toward the receiving surface, the full-cut blade completely cuts both the adhesive tape and the release paper, and at the same time, the half-cut blade cuts either the adhesive tape or the release paper. Half cut is applied to the print-receiving tape.

[0004]

In such a cutting device, since the cutting edge of the full-cut blade is projected more than the half-cut blade, when cutting the print-receiving tape, the cutting edge of the half-cut blade directly receives the receiving surface. However, the cutting edge of the full-cut blade directly contacts the receiving surface. For this reason,
When used for a long period of time, the sharpness of the full-cut blade becomes poor, or the receiving surface is scraped by the full-cut blade. When the sharpness of the full-cut blade becomes poor like the former, it is not possible to cut the print-receiving tape satisfactorily, so it is necessary to replace the full-cut blade. Since it is attached to one support in an exposed state, there is a risk that the half-cut blade may injure the operator when replacing the full-cut blade, and the replacement work cannot be performed safely. is there. If the receiving surface is scraped as in the latter case, it will be impossible to reliably perform half-cutting on the print-receiving tape, so it is necessary to replace the receiving surface, but the receiving surface is provided separately from the support base. Therefore, when the blade is replaced, the receiving surface cannot be replaced at the same time, and there is a problem that the replacement work is complicated and troublesome. The present invention has been made in view of the above circumstances, and an object thereof is to allow a worker to perform a safe replacement work without injury during replacement of a cutting blade, and also to replace a receiving surface at the same time. It is to provide a cutting device capable of performing.

[0005]

In order to achieve the above object, the present invention is a first cutting blade for completely cutting both an adhesive tape and a release paper of a member to be cut in which a release paper is attached to the adhesive tape. And a first supporting member having a first receiving portion, a second supporting member having a second cutting blade that cuts only one of the adhesive tape or the release paper of the member to be cut, and the second receiving portion, A connecting member that connects the first supporting member and the second supporting member so as to be movable in the directions in which the first cutting blade and the second receiving portion face each other and the second cutting blade and the first receiving portion face each other; And a member to be cut is arranged between the first support member and the second support member, and in this state, the first support member and the second support member are moved in directions toward each other to perform the first cutting. Press the member to be cut against the second receiving part with the blade to make a full cut, Pressed to be cut members to a first receiving portion at the cutting edge, characterized in that the half-cut.

[0006]

According to the present invention, the first supporting member is detached from the connecting member when the first cutting blade is replaced, and the second supporting member is detached from the connecting member when the second cutting blade is replaced. Since both need to be replaced separately, when replacing either one of the first cutting blade and the second cutting blade, the risk of injury to the operator due to the other cutting blade is reduced, and the replacement work is performed safely. Moreover, when the first cutting blade and the second cutting blade are replaced, the first and second receiving parts can be replaced at the same time, and the receiving parts can be replaced efficiently. ..
