Abstract

PURPOSE:To prevent paper from falling rearward of a printer body after a printing output. CONSTITUTION:A front discharge guide 1 is mounted on a dust protective cover covering roll-form paper 5 so as to be erect at a paper discharge port 7a. A guide surface 1a connecting to the paper discharge port 7a is formed to be bent to a front F of a printer body P. Printed paper 5a discharged from the paper discharge port 7a is guided to the front of the printer body P along the guide surface 1a of the front discharge guide 1, therefore never falling to the rear B of the printer body P.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to printers, and more particularly to a paper ejection mechanism for a printer equipped with a paper cutting mechanism.

0002

2. Description of the Related Art A conventional paper ejection mechanism has a stacker provided at a paper ejection port, and cut sheets are stacked on the stacker.

0003

In the conventional paper ejection mechanism described above, the length of the stacker is limited, so if the ejected paper becomes long, the paper cannot be stored in the stacker. Therefore, when cutting the paper, the paper falls to the rear of the apparatus, and depending on the environment in which the apparatus is installed, it becomes difficult to take out the fallen paper.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printer that prevents cut paper from falling to the rear of the apparatus.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the printer according to the present invention has a front ejection guide, prints on the paper while feeding out the roll paper, and prints on the paper after printing is completed. This is a printer that uses a paper cutting mechanism to cut the paper into the required length for output, and the front ejection guide is attached to a dustproof cover that covers the roll of paper and stands up against the paper ejection port. The guide surface connected to the paper ejection port is curved toward the front of the printer body, and the curved guide surface of the front ejection guide guides the output paper toward the front of the printer body. .

Further, the front ejection guide is configured as a paper winding guide curved in an arc shape, and the paper winding guide outputs the paper along the guide surface curved in the arc shape. The paper is rolled up and stored.

[0007] Furthermore, the front ejection guide is constructed as a paper holder, and the paper holder is for holding the output paper between it and the dustproof cover.

[0008]

[Operation] In the paper ejection mechanism shown in FIG. 1, the output paper 5a is guided to the front F side of the printer main body by the guide surface 1a of the front ejection guide 1, and in the paper ejection mechanism shown in FIG. The output paper 5a is wound up and stored in the take-up guides 3a and 3b, and the output paper 5a is held between the dustproof cover 4 and the paper presser 2 in the paper ejection mechanism shown in FIG. This prevents the paper from falling to the rear of the printer main body P after printing is completed.

[0009]

[Embodiments] Hereinafter, embodiments of the present invention will be explained with reference to the drawings.

(Embodiment 1) FIG. 1 is a side sectional view showing Embodiment 1 of the present invention, and FIG. 2 is a side view showing the dustproof cover of FIG. 1 in an open state. In the figure, the printer main body P stores a roll of paper 5 covered with a dustproof cover (stacker), and the paper 5 is fed out to the required length and wrapped around the platen 8 for printing. was carried out,
The printed paper 5 is cut into a required length by a paper cutter 6 serving as a paper cutting mechanism, and is outputted from a paper outlet 7a of a cutter cover 7.

In this embodiment, the front discharge guide 1 is rotatably supported around the tip of the dustproof cover 4 as a fulcrum shaft, and when the dustproof cover 4 is closed as shown in FIG. is provided upright with respect to the paper discharge port 7a, and further,
The guide surface 1a of the front discharge guide 1 is curved toward the front of the printer main body P with the paper discharge port 7a as a starting point.

Therefore, the paper 5a cut and output by the paper cutter 6 is guided by the guide surface 1a of the front discharge guide 1 and is discharged to the front of the printer main body P. Thereby, the paper 5a does not fall behind the printer main body P, and the ejected paper 5a can be easily taken out.

(Embodiment 2) FIGS. 3 and 4 are side sectional views showing Embodiment 2 of the present invention. In the figure, this example shows
The front discharge guide is configured as a paper winding guide 3a or 3b curved into an arc shape.

The paper winding guide 3a shown in FIG. 3 has one end attached to the cutter cover 7 at a position above the paper outlet 7a, and the other end placed on the dustproof cover 4.
The output paper 5a is wound up and stored between the arc-shaped guide surface 3c and the dustproof cover 4. This prevents the paper 5a discharged from the paper discharge port 7a from falling to the rear B of the printer main body P.

Furthermore, a winding guide 3 shown in FIG.
3b, the radius of curvature of the arc-shaped curvature is made smaller than that of FIG. 3, and the paper 5a is wound up and stored within the guide 3b.

(Embodiment 3) FIG. 5 is a side sectional view showing Embodiment 3 of the present invention. In this embodiment, the cutter cover 7
The tip of the paper holder 2 attached to the dust cover (
stacker) 4. Ejected paper 5a
passes between the stacker 4 and the paper holder 2 and hangs down to the rear B of the printer main body P. Even if the paper 5a is cut by the paper cutter 6, it does not fall because it is pressed onto the stacker 4 by the paper presser 2.

[0017]

As described above, according to the present invention, the paper is ejected to the front of the printer main body by the front ejection guide, so that the paper can be easily taken out without falling to the rear of the printer main body. Further, since the paper is wound and stored by the paper winding guide curved into an arc shape, the paper can be easily taken out without falling behind the printer main body. Further, since a paper press is provided on the paper path after being ejected to hold the cut paper, it is possible to prevent the cut paper from falling behind the printer main body.
