JPH0327963A - Card holder of printer - Google Patents

Abstract

PURPOSE:To dispense with a paper bail roller by designing so that printing paper is introduced along a card holder and a platen and then is discharged, held by a roller installed on the card holder. CONSTITUTION:The tip of printing paper 10 passes through a printing head 5 and a platen 1 and then proceeds to a window 6 provided on a card holder 2. The window 6 is curved so that it does not protrude outward. The printing paper 10 passes through the card holder 2 and the platen 1 along the curve, reaching a roller 4 installed in such a manner that it rotates with a shaft 3 of the card holder 2 as a center. As the roller 4 rotates backward by the rotary force of the platen 1, the paper 10 comes out in a discharge direction, passing through an area between the roller 4 which rotates with the shaft 3 of the card holder 2 as a center and the platen 1. Thus a paper bail roller becomes unnecessary.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a card holder for a printer, which is provided in a printer device to allow printing paper to run along a platen of the printer.

[Conventional technology]

Referring to Figure 4, the conventional printer card holder 2
0 was attached to a carrier on which the print head 5 of the printer was mounted, and moved together with the movement of the carrier. Therefore, it is designed to have a small structure,
The printing paper 1o was not held down by the entire width of the card holder 20, and there was no card holder at the top, so a separate Pehahaheru 11 was required.

[Problem to be solved by the invention]

The card holder of the conventional printer described above does not hold the print paper across the entire width of the platen, and the upper part is also short, so in order to prevent the leading edge of the paper from floating away from the platen as it travels in the ejection direction. It has the disadvantage that it must be held down with a paper veil, and that the opening and closing of the paper veil must be controlled manually or automatically.

[Means to solve the problem]

The printer card holder of the present invention has a window that allows the print head of the printer to move left and right, has a curved shape along the platen so as to cover almost the entire width of the platen, and has a It is equipped with rollers that press the paper against the platen. This roller rotates in a direction opposite to that of the platen due to the rotational force of the platen, and also serves to feed the printing paper.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention. In FIG. 1, the card holder 2 of the present invention has a window 6 through which the print head 5 of the printer can move from side to side, and is equipped with a roller 4 that rotates around a shaft 3 so as to be brought into close contact with the platen 1. and is attached to the printer body (not shown).

2 and 3 are side views of the embodiment shown in FIG. 1, showing the state before and after the printing paper 10 is sucked, respectively. In FIG. 2, the print paper 10 sucked in from the rear pressure roller 7 reaches the front pressure roller 8 along the paper guide 9, and the front pressure roller 8 causes the print paper 10 to run in the direction of the print head 5. The leading edge of the printing paper lO that has been run by the front pressure roller 8 passes between the print head 5 and the platen 1 and goes in the direction of the window 6 provided in the card holder 2; The window 6 is curved so that it does not come out, and the printing paper 10 passes between the card holder 2 and the platen 1 along the curved part, and is rotated around the shaft 3 by the card holder 2. The mounted roller 4 is reached.

The roller 4, which is attached to rotate around the shaft 3 of the card holder 2, is rotated in the opposite direction by the force of the rotation of the platen 1, so that the printing paper IO is rotated around the shaft 3 of the card holder 2, as shown in FIG. The paper passes between the platen 1 and a roller 4 mounted to rotate around a shaft 3, and exits in the discharge direction.

〔Effect of the invention〕

As explained above, the present invention has the effect of eliminating the need for a paper bail by inserting printing paper along the card holder and platen, pressing it down with the roller attached to the card holder, and exiting in the ejection direction. .
