Abstract

PURPOSE:To prevent a paper sheet from its diagonal feed with uniformly pressing force given to the paper sheet despite a guide plate in its mounting condition and the paper sheet in its fold habit condition by enabling a paper sheet retaining plate, for pressing the paper sheet to a delivery roller side, to be oscillated. CONSTITUTION:A guide 2 is provided before a delivery roller 1, and a holding member 4, urged to a side of the delivery roller 1 by a spring, holds a paper retaining plate 5 so as to be oscillatable by a pin 6 through a hole 5a, pressing a paper sheet 7 to the side of the delivery roller 1 and delivering the paper sheet to a separator roller side by rotating the delivery roller 1. The paper sheet 7 can be pressed uniformly to the guide 2 by enabling the paper retaining plate 5 to oscillate. While even in case of a fold habit or the like being generated in the paper sheet 7, by oscillating the plate 5 in accordance with reaction force of the paper sheet 7, it is given pressing force, enabling stable delivery to be attained with a less diagonal feed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper sheet feeding mechanism, and more particularly to a paper sheet feeding mechanism that has an improved paper sheet pressing plate for pressing paper sheets against a feeding roller side.

[Conventional technology]

This type of paper pressing plate in a conventional paper feeding mechanism is configured to press the paper against the feeding roller while being fixed to a holding member.

[Problem to be solved by the invention]

The conventional sheet pressing plate described above presses the sheet against the feeding roller while being fixed to the holding member, so if the sheet is not parallel to the guide provided in front of the feeding roller, the sheet will The pressing force becomes uneven on the left and right sides, and as a result, a uniform frictional force cannot be obtained between the sheets or between the sheets and the guide, which causes the unfed sheets to run diagonally, which can lead to poor sheet conveyance. The problem was that it could cause problems.

Of course, the above problem can be solved by sufficiently adjusting the parallelism between the guide and the sheet holding plate, but not only does the adjustment require a lot of effort, but it may also cause curls in the sheets. This method has the drawback that force is applied to only one part of the paper sheet, and the fed paper sheet is skewed as described above.

[Means to solve the problem]

The paper sheet feeding mechanism of the present invention includes a feeding roller, a guide provided between the feeding roller and one side of the paper sheet, and a paper sheet pressing plate that presses one sheet of paper against the feeding roller from the other side. , and a holding member that holds the paper leaf pressing plate,
In the paper sheet feeding mechanism, the sheet pressing plate is biased toward the feeding roller side, and the paper sheet is inserted between the paper sheet and the guide, and the paper sheet is fed out by the feeding roller with frictional force applied thereto. It is characterized in that the presser plate is held by the holding member so as to be swingable.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a side sectional view showing one embodiment of the present invention, and FIG. 2 is a plan sectional view. A guide 2 is provided in front of the feeding roller 1, and a spring 3 causes the feeding roller 1 to
A paper sheet pressing plate 5 is held in a swingable manner by a bottle 6 through a hole 5a provided in the paper sheet pressing plate 5 on the holding member 4 which is biased toward the side, and presses the sheet 7 against the feeding roller 1 side. Since the sheet holding plate 5, which feeds out eight sheets on the peeling roller 9 side by the rotation of the feeding roller 1, can be swung, the installation of the guide 2 can press the sheets 7 uniformly against the guide 2 regardless of the state. It is possible to attach it. Moreover, as shown in FIG.
Even if the sheet is bent, etc., the pressure is applied only to the most convex part 8a of the sheet on the side of the sheet pressing plate with the conventional fixed sheet pressing plate. By shaking the head in response to the reaction force of the sheet 7, a pressing force is also applied to the portion 8b of the sheet 7, allowing stable feeding with less skew.

〔Effect of the invention〕

As explained above, the present invention makes it possible to oscillate the sheet pressing plate, so that the guide can be mounted without complicated adjustments and can be pressed uniformly regardless of the state or the folded state of the sheet. can apply force to the paper sheets, so the frictional force between the paper sheets or between the guide and the paper sheets becomes uniform on the left and right sides.
This has the effect of allowing feeding without skewing.
