Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a recording paper entrapment prevention device suitable for desktop electronic computers with printers and the like.

(B) Prior Art Generally, in a desk computer with a printer, etc., as shown in FIG. The recording paper 1 is inserted into the printer 4 through a paper insertion slot 3, and the printed recording paper 1 is discharged from an upper opening 5.

However, in this method, there is a problem that the printed recording paper 1 gets caught in the recording paper insertion slot 3 as shown in FIG. Although the entrainment prevention metal fitting 6 was provided near the recording paper insertion slot 3, this required the entrainment prevention metal fitting 6 and a process for attaching it, which increased costs.

Therefore, as disclosed in Japanese Utility Model Application Publication No. 56-94354, a structure has been proposed in which ribs are integrally formed above and below the insertion opening.

(c) Problems to be solved by the invention As shown in FIG. 8, the structure disclosed in the publication is such that the recording paper 1 is always in contact with the rib 20,
By ensuring that there is no gap between
This is to prevent entanglement.

However, in such a configuration, since the recording paper in the insertion slot is held flat, if the leading edge of the printed recording paper discharged from the opening 5 pushes the recording paper near the insertion slot 3 downward, the recording paper in the insertion slot 3 will be held flat. There is a problem in that a gap is created between the recording paper and the rib 20, and the leading end is caught in the gap.

(d) Means for solving the problem The present invention was made in view of the above points, and its structural features are: a recording paper insertion slot formed in the front wall of the device; A printer that prints on recording paper inserted through an opening, a device comprising an opening formed above the device for ejecting the printed recording paper, and a plurality of ribs formed above and below the insertion opening. In the above, the ribs are arranged in approximately one row along the opening surface of the insertion opening, and the rib formed at the upper part of the insertion opening has a length such that the rib formed at the lower part and the tip thereof partially overlap each other. It is in having.

(e) Effect In this configuration, the recording paper is inserted into the insertion slot in a waved manner in the extending direction of the insertion slot.

(f) Examples Examples of the present invention will be described below with reference to the drawings. 7 in Fig. 4 is a recording paper insertion slot improved according to the present invention, which has two ribs 8, 8' on the upper side and one rib on the lower side.
8" is formed. Ribs 8, 8', 8" are the fifth
As shown in the figure, in order to facilitate the insertion of the recording paper 1, the front side is inclined, and the leading ends are formed to a length that partially overlaps each other. Therefore, the recording paper 1 is inserted in the state shown in FIG. 6, and even when the printed recording paper reaches the recording paper insertion slot 7, it hits the ribs 8, 8' and does not get caught inside.

Furthermore, as is clear from FIG. 6, the top surface of the recording paper 1 is always in contact with the ribs 8, 8', and the bottom surface is always in contact with the rib 8''.
The recording paper 1 is inserted with its cross section bent along the extending direction of the insertion opening 7 (left-right direction in the figure). Therefore, even when the leading edge of the printed recording paper discharged from the opening 5 presses down the recording paper near the insertion slot 7,
Since the leading end is not bent like the recording paper in the insertion slot 7, there is no risk of it getting caught in the insertion slot 7.

It should be noted that the equipment has an upper cover 9 and a lower cover 10 as shown in FIG.
When the recording paper insertion slot 7 is formed by the recesses 11 and 12, the ribs 8 and 8' are integrally molded on the upper lid 9, and the rib 8'' is integrally molded on the lower lid 10. Ribs 8, 8', 8'' can be easily formed.

(g) Effects of the invention According to the invention, there is no danger of printed recording paper being entangled.
