Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driven roller mechanism for a paper-conveying bent conveyance path, and more particularly to a paper-conveyed bent-conveyance driven roller mechanism for conveying paper sheets having different thicknesses.

[0002]

2. Description of the Related Art A conventional driven roller mechanism for a paper-conveying bent conveyance path will be described in detail with reference to the drawings.

FIGS. 4 (a) and 4 (b) are cross-sectional views showing an example of the related art. (See, for example, Japanese Patent Application Laid-Open No. Hei 4-20443.) In FIG. 4A, papers 7 are sandwiched between a feed roller 3 and a driven roller 4 between an upper paper guide 1 and a lower paper guide 2a, and are moved in the direction of arrow A. When the sheet is conveyed, when it is connected to the feed roller 5 and the driven roller 6 disposed at the back of the bent portion, the conveyance path is bent.
When the angle between the paper and the paper 7 approaches a right angle, the paper and the paper 7 collide with the driven roller 6 to induce a sheet jam.

In FIG. 4B, a rib-shaped projection 20 is formed on the lower paper guide 2b on both sides of the driven roller 6, and the angle formed between the driven roller 6 and the paper 7 is increased so that the feed roller 5 and the driven roller 6 are formed. To make a smooth transfer.

[0005]

According to the first prior art described above, paper jams such as a passbook do not cause a jam, but a thin paper such as a single sheet does. According to the second conventional technique, no jam occurs in a thin sheet such as a single sheet of paper, but a thick paper sheet such as a passbook increases the load when passing through a bent portion, resulting in poor conveyance. There was a disadvantage.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a driven roller mechanism for a paper-conveying bent conveying path comprises a first and a second feed roller and a first and a second feed roller between an upper paper guide having a bent portion and a lower paper guide. And a driven roller mechanism of a paper-conveying bent conveying path which conveys the paper-conveyed material by being sandwiched between the second driven rollers and extending the arm holding the second driven roller from the lower paper guide. The paper arm is guided by the protruding swing arm, and the swing arm is guided by the swing arm.
Is given an appropriate pressing force by a spring,
Swing up and down according to thickness.

[0008]

Next, the present invention will be described in detail with reference to the drawings.

FIGS. 1A and 1B are cross-sectional views including an embodiment of the present invention. 1 (a) and 1 (b), a driven roller mechanism for a paper-conveying bent conveyance path is provided between a feed roller 3, 5 and a driven roller 4, between an upper paper guide 1 and a lower paper guide 2 having a bent portion. In a driven roller mechanism of a bent transport path for papers which transports papers 7 while being sandwiched between them, a swing arm 10 in which an arm holding the driven rollers 6 is extended and protruded from the lower paper guide 2.
Guides paper items.

The swing arm 10 is given an appropriate pressing force by a spring 11, and swings up and down according to the thickness of the paper. For paper class 7, which is one sheet of paper,
The swing arm 10 moves up to prevent a collision with the driven roller 6 and avoid a jam.

FIG. 2 is a top view showing details of the swing arm 10 shown in FIG.

FIGS. 3A and 3B are side views showing examples of use of the present invention. When a thick passbook 8 made of a plurality of papers strikes the swing arm 10 (FIG. 3A), the swing arm 10 is lowered and the transport path is automatically adjusted so that the passbook 8 can be easily passed (FIG. 3A). 3 (b)).

[0013]

According to the present invention, the driven roller mechanism for the paper sheet bending conveyance path automatically adjusts the conveyance path according to the thickness of the paper sheet to be inserted, so that there is no jam.
