Description

The present invention relates to a double-sided label, and more particularly to a double-sided label having a three-layer structure in which labels are temporarily attached to the front and back surfaces of a belt-like mount.

Conventional thermal printers include a thermal head and a platen roller, and perform thermal printing with a thermal printing paper sandwiched between them, but print only on one side of the thermal printing paper.
Therefore, from the standpoint of resource saving and environmental conservation, a thermal printer for double-sided printing that can perform printing on both the front and back sides of thermal printing paper has been proposed (for example, see Patent Document 1).
This thermal printer for double-sided printing includes a first pair of a first thermal head and a first platen roller for front side printing, and a second pair of a second thermal head and a second platen roller for backside printing. However, there are problems that the pitch of the thermal printing paper is the same size on both the front and back sides, and that the printing areas on the front and back sides must be at the same position.
However, as the actual usage form, the size of the printing paper on the front and back sides may be different, and in order to expand the usage form or application form, it is possible to deal with cases where the size on the front and back sides is different. It is desirable to be.

In addition, when using a label continuous body consisting of a strip-shaped mount (release paper) and a plurality of label pieces temporarily attached to the front side of the mount as the thermal printing paper, the label back unit is provided on the back side of the mount for each label piece unit. A position detection mark is printed in advance, and this is detected by a reflective sensor provided in the printer, and used for detecting the position of the label piece.
However, in the case of a double-sided label with a three-layer structure in which labels are temporarily attached to the front and back surfaces of the mount, the problem of where the print position of the position detection mark is optimal, and the pitch sizes on the front and back surfaces are different. Even when a double-sided label having a label piece is loaded, there is a problem that it is necessary to prevent the position of the label piece from being shifted on the front and back surfaces for each printing of the label piece.

    The front surface side separation slit has a front surface upstream slit located at the upstream edge of the front surface position detection mark and a front surface downstream slit located at the downstream edge, and the rear surface side separation. The slit for use has a back-surface upstream-side slit located at the upstream edge of the back-surface-side position detection mark, and a back-surface downstream slit located at the downstream edge, and further for detecting the surface-side position. The mark is formed in a front side raised portion between the front surface upstream slit and the front surface downstream slit, and the rear surface position detection mark is formed by the rear surface upstream slit and the rear surface downstream slit. This can be formed at the back side raised portion between the two.

The front surface upstream side slit and the rear surface upstream side slit can form these at the same position on the front and back of the double-sided label.
That is, the front-side label piece and the back-side label piece can be positioned at the same position at each edge by positioning each position detection mark at the upstream edge.
