Abstract

PURPOSE:To enable a feed action free from a paper jamming caused by a paper stapler part on the edge part of pressure-sensitive paper and superior in reliability by a construction wherein step parts are provided on a printing paper running part of a platen outside a printing range part. CONSTITUTION:Step parts 6, 7 are provided on a platen 3 outside a printing range 3a of printing paper to be one step lower than the surface of the printing range 3a. In the printing conducted by a printing head 5 with pressure-sensitive paper 4 loaded on the platen 3 constructed as the above, a paper stapler part 4a is pressed down to the step part 6 or 7 when a card holder 1 reaches the paper stapler part 4a. Therefore, in the condition that the projection on the paper stapler part 4a is released to the step part 6 or 7, the pressure-sensitive paper 4 held between the card holder 1 and the platen 3 can be easily fed.

As mentioned above, when pressure-sensitive paper is used as printing paper, conventional platens are equipped with a card holder between the platen and the print head to hold down the printing paper. has a paper staple section that binds the edges of pressure-sensitive paper for printing, and when this paper staple section comes to the printing position, the gap between the platen and card holder is extremely large due to this paper staple section. This has the disadvantage that the width of the printing paper becomes narrow, leading to paper jams and hindering the conveyance operation of the printing paper.

That is, the platen of the present invention has a flat card holder disposed between it and the print head, the surface facing the print head is formed in a flat shape, and the platen is inserted between the card holder and conveyed. In a platen of a printer that prints on pressure paper using the print head, a stepped portion is provided at a portion corresponding to a paper stapler section for binding the edges of the pressure-sensitive paper by a predetermined dimension lower than the surface facing the print head. It was established.

In FIG. 1, the platen 3 is a printing area 3a of printing paper.
Step portions 6 and 7 which are lower than the surface of the printing range 3a are provided on the outer side. When the pressure-sensitive paper 4 is placed on the platen 3 having such a configuration and the print head 5 prints, the card holder 1 disposed between the print head 1 and the platen 3 binds the edges of the pressure-sensitive paper 4. When the card holder 1 reaches the paper stapler section 4a, the paper stapler section 4a is pushed down toward the stepped section 6 or 7 by the card holder 1. Therefore, the protrusion of the paper stapler part 4a is connected to the platen 3.
The pressure-sensitive paper 4 can be easily conveyed between the card holder 1 and the platen 3 by letting the pressure-sensitive paper 4 escape toward the stepped portion 6 or 7.

As explained above, the present invention conveys pressure-sensitive paper on the platen for printing by providing a stepped portion lower than the surface of the platen in a portion outside the printing range of the paper running portion of the platen. When the card holder is placed above the paper staple part of the pressure-sensitive paper, the paper staple part will be pushed toward the stepped part provided on the platen, so make sure that there is a sufficient gap between the card holder and the paper staple part. Therefore, it is possible to prevent paper jams from occurring in the printer and paper conveyance failures.
