Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a printer that uses continuous paper having a plurality of perforations on the sides of the paper.

FIG. 1 shows a paper feed tractor attached to, for example, a printer 1. 2 is a tractor main body, 3 is a caterpillar part, and inside thereof is a drive shaft 4.
It has a caterpillar which is an endless circulating moving body that circulates by the rotation of the paper, and the caterpillar is equipped with a plurality of feed pins 5 that engage with paper feed holes. Reference numeral 6 denotes a press plate which is an opening/closing member that presses the paper.

When feeding the paper, the feed holes provided at both ends of the paper are engaged with the respective feed pins 5 of the two caterpillar sections 3 set to the width of the paper, and the paper is pressed down with a presser plate 6 from above. The press plate 6 is pulled in the closing direction by a spring having an appropriate tension to prevent the paper from coming off. Then, the paper is fed by the circular movement of the caterpillar.

By the way, when setting the paper on the caterpillar section 3, the presser plate 6 is opened and the presser plate 6 is closed while the feed pin 5 and the paper feed hole are engaged. It is necessary to hold the paper with your fingertips so that it does not come off the feed pin 5 until it is closed. When you close the presser plate 6 while pressing the paper with your fingertips, the presser plate 6 is pulled in the closing direction by the spring as described above, so the presser plate 6 hits your fingertips strongly, or the presser plate and the This was extremely dangerous as the fingertips could get caught between the parts.

The present invention solves the drawbacks of the conventional example described above, and even when closing the opening/closing member while holding part of the paper with your finger when setting continuous paper with multiple holes in the printer, the opening/closing member does not close. To provide a highly safe printer that reduces the risk of damaging fingertips. Hereinafter, embodiments will be described in detail with reference to the drawings.

Figure 2 shows an embodiment of the present invention.
Reference numeral 7 denotes a presser plate, which is provided with a notch 7a through which a fingertip pressing the paper 8 can escape when the presser plate 7 is closed. Note that 9 is a feed hole in the paper 8, which is engaged with the feed pin 5.

Further, as shown in FIG. 2, an inner facing member 21 is provided along the plurality of feed pins 5 to face a portion of the paper inside the feed hole. The press plate 7 can be opened and closed between a closed position close to the inner facing member 21 and an open position for setting paper.

In this embodiment configured in this way, even if the paper is set and the presser plate 7 is closed with the portion of the paper corresponding to the inner facing member 21 pressed with the fingertip, the inner facing member 21 of the presser plate 7 will not be pressed. Since the notch 7a is provided in the opposing portion, the presser plate 7 does not hit the fingertip or pinch the fingertip, making it safe.

Figures 3A and 3B each show other embodiments of the present invention, and 11 and 12 are holding plates whose rotational axis is the X axis, and each has a notch for the fingertip to escape. Sections 11a and 12a are provided.

FIG. 4 shows still another embodiment of the present invention, in which a bent portion 13a is provided in a part of the presser plate 13,
This prevents the presser plate 13 from hitting the fingertips when it is closed.

FIG. 5 shows still another embodiment of the present invention, in which a portion of the presser plate 14 is cut out and the end portion 14a of that portion is bent.

By the way, when actually setting the paper, it is necessary that the position of the fingertip that presses the paper coincides with the notch or folded part of the presser plate. FIG. 6 shows the presser plate 15
Caterpillar guide 16 corresponding to the notch 15a of
A recessed portion 16a may be provided in a portion of the paper, and the paper may be pressed with a fingertip using this portion as a guide.

As explained above, according to the present invention, when setting paper in the printer, the opening/closing member for preventing the paper from coming off can be closed even if the part of the paper inside the paper feed hole is pressed with a finger. At the same time, there is an advantage that safety is improved because the opening/closing member does not strongly hit the fingertips or the fingertips are not pinched. Furthermore, since the inner opposing member is located inside the paper feed hole, it is possible to firmly press the paper with your fingertips.
The feed pin and feed hole are now difficult to separate.
