Abstract

PURPOSE:To provide easier handling and higher economical effect of a printer by providing plural ribs whose height are different from each other at the sheet discharge guide of a printer body in the same direction as the discharged sheet, and warping printed sheet to hold discharged sheet at the prescribed position. CONSTITUTION:A discharged sheet guide 2 which holds a printed sheet 4 which is also used for a rear cover is engaged at the back part of a printer body 1, and is held at the printer body 1 at a particular angle. Plural ribs 3 whose height are different from each other are provided at the sheet guide 2 in parallel to each other. With this constitution, the sheet 4 which is printed by a printer head is discharged from a discharge opening 10 under the condition where both the sides of the printed sheet 4 are supported when the printed sheet 4 is discharged along the highest rib among the plural ribs 3 provided on right and left sides at the discharged sheet guide 2, and the warped printed sheet 4 stands by itself. It is thus possible to prevent the printed sheet 4 from hanging down to be bent.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet holding device for holding printed sheets of cut sheets of a printer used in a word processor or the like.

[0002]

2. Description of the Related Art FIG. 2A is an external view of a printer device including a conventional paper holding device.

As shown in FIG. 2, hinges 9 that can be opened and closed are provided on the back side of the printer body 1 on the left and right sides. There is. The paper ejection guide 5 is provided with a through hole 7 for holding the pair of left and right extension guides 6 and a step for aligning the surfaces when held. The extension guide 6 has a U-shape and is provided with a protrusion 8 on the inner side. The extension guide 6 is inserted from one end side of the paper ejection guide 5 by utilizing the elasticity of the molded product, and the protrusion 8 and the through hole
Are engaged and held in place. Also, the paper ejection guide 5
Can be expanded and contracted up and down. When printing, the left and right extension guides 6 are pulled out to hold the printing paper.

[0004]

However, in the paper holding device provided in the conventional printer described above, if the printer power is supplied from the word processor main body without incorporating the printer power into the printer, the depth dimension of the printer housing will be considered. (C dimension in FIG. 3) becomes smaller, and the depth dimension of the paper ejection guide (D dimension in FIG. 3) becomes inevitably smaller. Even if the auxiliary guide is pulled out and used as shown in FIG. 2C, A3 paper is used. However, there is a problem that the absolute size for holding the A3 sheet is not secured when the sheet is printed on the sheet and the like, and the sheet hangs down on the back surface of the printer as shown in FIG. 3 or drops from the printer device.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a paper holding device which improves the usability of the printer device and can realize an economical effect.

[0006]

In order to achieve the above object, the present invention has a structure in which a discharge guide is provided with a plurality of ribs having different heights, and the discharged print paper is curved by using the rib as a guide. Have.

[0007]

According to the present invention, since the discharged printing paper is curved in the shape of the rib of the discharging guide in the above-mentioned structure, the holding dimension of the printing paper is small and the curved shape even if the printing paper is larger than the discharging guide. As it is, the sheet itself becomes self-supporting, and as shown in FIG. 3, it is possible to prevent the sheet from hanging down or dropping to the rear surface of the printer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1A shows the structure of an embodiment of the present invention. FIG. 1B is a view as seen from the arrow B of this embodiment.

In FIG. 1 (a), hinges 9 that can be opened and closed are provided on the back side of the printer body 1 on the left and right sides, and a paper discharge guide 2 that also holds a print paper also serving as a rear cover is engaged.
The paper ejection guide 2 is held by the printer body at a constant angle. A plurality of ribs 3 having different heights are provided in parallel on the paper guide 2. As shown in the cross-sectional view of FIG. 1B, the ribs 3 are provided with ribs whose both ends of the paper ejection guide 2 are higher than the central portion. With this structure, the paper printed by the printer head is discharged from the paper discharge port 10,
As the print paper is discharged along the highest ribs 3 on the left and right on the paper discharge guide 2, the print paper is discharged while being supported at both ends.
As shown in FIG. 1 (b), the printing paper itself is curved and self-supporting, and bending of the printing paper due to sagging can be prevented.

As described above, according to the sheet holding apparatus of the embodiment of the present invention, since the plurality of ribs having different heights are provided on the sheet ejection guide, the ejected sheet is curved, and the sheet itself stands. However, it does not sag.

The rib may be formed integrally with the discharge guide or may be formed integrally.

[0012]

According to the present invention, as is apparent from the above-described embodiment, it is possible to hang or drop a sheet only by processing a plurality of ribs having different heights on the molding die of the sheet ejection guide. Therefore, it is possible to provide a sheet holding device which has a smaller number of constituent parts than the conventional one and has an economical effect including the number of assembling steps and die investment.
