Abstract

PURPOSE:To increase the number of printing lines without the possibility that card-form printing paper may be caught by a paper guide by a method wherein after printing paper wound in a roll form is guided along the paper guide, a paper discharge path is changed over. CONSTITUTION:For setting roll-form printing paper 1 to a printing state, the roll-form printing paper 1 is clamped between a sub-paper feed roller 2 and a sub-paper feed presser roller from an arrow direction A, passed through between a paper presser plate 4 and a platen 5 by the rotation of the sub-paper feed roller 2, and further fed between a printing head 10 and the platen to abut on a paper guide 6. Thereafter, the paper 1 is guided toward a paper feed roller 8 and a paper presser roller 7 to be clamped between the both rollers 7, 8. Furthermore, the roll-form printing paper 1 is discharged by the rotation of the paper feed roller 8. A paper guide lever part 9 of the paper guide 6 is lifted by the roll-form printing paper 1, and the top end of the paper guide 6 is rotated in an arrow direction C to be depressed on the platen. In this manner, the feed paths for roll-form printing paper and card-form printing paper can be changed over.

[Function] The paper feeding device in the printer configured as described above is as follows:
When the roll of printing paper is set in a state ready for printing, the roll of printing paper is sent out between the platen and the paper presser plate by the rotation of the sub paper feed roller, passes between the platen and the print head, and is sent out to the paper guide. Next, the rolled printing paper is guided by the paper guide so as to be sandwiched between the paper feed roller and the paper feed pressing roller, and the rolled printing paper is further pushed up by lifting a part of the paper guide lever, so that the paper guide moves toward the tip of the paper guide. rotates toward the platen side to ensure a path for the card-shaped printing paper. Therefore, with the rolled printing paper set, a path can be secured when the card-shaped printing paper is inserted from below and discharged upward, and a path can be secured when the ink ribbon is removed, thereby achieving the object of the invention.

The paper guide 6 has a built-in spring, and is open when the rolled printing paper 1 is not set in a printing state. That is, the paper guide lever part 9 of the paper guide 6 is located so as to intersect with the paper path of the rolled printing paper 1. (Fig. 1) The operation will be explained below. In Fig. 1, in order to set the rolled printing paper 1 in the printing state, it is held between the sub paper feed roller 2 and the sub paper feed press roller 3 from the six directions of the arrows. By the rotation of the sub paper feed roller 2, the rolled printing paper l passes between the paper press plate 4 and the platen 5, and after passing between the print head 10 and the platen, it comes into contact with the paper guide 6, and the paper feed roller 8 and It is guided toward the paper pusher roller rough and is held between the paper feed roller 8 and the paper pusher roller rough. Further, the rolled printing paper 1 is ejected by the rotation of the paper feed roller 8, and as shown in FIG. , can be rotated in the direction of arrow C, pressed against the platen side, and can perform the operation of switching the path between the roll-shaped printing paper and the card-shaped printing paper.
