Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to paper for printing with a recording device, and particularly to label paper in which adhesive-coated paper and release paper are laminated together.

[Prior Art] As shown in FIG. 5(a), a label paper 10 is made up of an adhesive-coated printing paper 11 and a release paper 12. A recording device prints on a certain divided area, and the area is printed on a release paper. It is convenient to peel it off from 12 and attach it to an envelope or the like for direct mail.

However, label paper IO is made by gluing together two different types of paper, and due to the difference in water absorption and thermal expansion coefficient between the two, it was in the state (a) at the time of manufacture, as shown in Figure 1. However, depending on the environment (temperature and humidity), the state may be in (b) or (c).

Furthermore, in recording devices that feed paper by wrapping it around a rubber roller, etc., when wrapped around the roller, the length of the paper changes because the inner release paper and the outer printing paper have different winding diameters. do. In order to stop this, a force is exerted on the outside of the roller that tends to cause it to fall.

[Problems to be solved by the invention] With label paper that curls due to the environment or is subjected to a large force that causes it to fall toward the outside of the roller when wrapped around the roller, it is necessary to For guiding, a large guide member or a movable guide member is required, which increases the size and cost of the device.

[Means for solving the problems] The present invention has been made in view of the above-mentioned conventional problems,
This provides reliable paper feeding of label paper.

According to the present invention, the above objects are achieved by eliminating large curls by removing the corners of label paper using C-chamfering or the like, and by guiding the paper reliably to the ejection port with a simple guide. It is.

[First example] Hereinafter, the present invention will be specifically described with reference to the drawings.

FIG. 1 is a perspective view of a label paper 10 according to an embodiment of the present invention, and FIG. 2 is a sectional view of a recording device (inkjet printer).

Figure 1 shows the release paper 12 (mounting paper) of the label paper lO.
When conveying with a recording device, notches 13 and 14 are provided at the corner of the leading edge.

When printing in the recording apparatus shown in FIG. 2, paper is inserted in the A direction along the paper pan 1, and the paper is set on the carrier 5 by the paper feed roller 2 and the pinch roller 3.4 pressed against it. The inkjet head 6 is sent onto the platen 7 located in front of the ink ejection opening 6', and recording is performed by ejecting ink. Then, the paper is pulled up in the B direction by several ejection rollers 8 having a certain width and a peeling wheel 9 that is pressed against each of the ejection rollers 8 with respect to the paper width direction.

When feeding label paper with the left and right upper edges removed as shown in Fig. 1 based on this configuration, Fig. 1(b),
As shown in (C), since the large curling portions at the upper left and right edges have been removed, the upper edge of the paper may slip under the ejection roller 8 or go outside the guide member 10 to the rolling wheel 9. It is possible to prevent the occurrence of paper jams due to paper jams.

[Other Embodiments] FIG. 3 is a perspective view of a label sheet according to a second embodiment of the present invention.

In this case, the left and right upper end portions 1344 are rounded, and the same effects as in the first embodiment can be expected.

FIG. 4 is a perspective view of a label sheet according to a third embodiment of the present invention.

In this case, only the printing paper 11 is removed at the corner portions 15 and 16, and the release paper 12 is left, and the same effect as the first embodiment can be expected.

[Effects of the Invention] As is clear from the above description, according to the present invention, stable paper feeding of label paper can be expected regardless of printing conditions.
