Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet handling apparatus which separates and conveys banknotes stored in a hopper like an automatic cash transaction apparatus. Things.

[Conventional technology]

In a conventional apparatus, for example, as described in JP-A-56-65733, a sheet stored in a hopper is sent downstream by a friction member provided on a pick-up roller, and thereafter, The next sheet comes into contact with a roller surface other than the friction member of the pick-up roller and is sent downstream.

[Problems to be solved by the invention]

In the above prior art, the conveying force of the outer peripheral surface of the roller other than the rubber portion of the pick-up roller is significantly smaller than the resistance force of the separation resistance portion that separates banknotes one by one. The bills are sent out by the transport force of the roller outer peripheral surface (eg, aluminum surface, stainless steel surface, plastic surface) other than the rubber portion of the pick-up roller. There is a problem that the period between the bill and the bill sent out by the section becomes extremely short or the bill is overlapped.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a paper sheet handling apparatus which always enables a constant feeding cycle.

[Means for solving the problem]

In order to achieve the above object, a high friction member is provided on a part of the outer periphery, and a roller protruding from the front plate of the paper stacking section is separated from the paper conveyed by the roller. A sheet handling device for separating and transporting the sheets stored in the stacking section, provided with a roller at a position always protruding from the front plate when the roller rotates, and only a high friction member portion. Has a guide for carrying paper sheets at a height at which only the high friction member of the front plate protrudes.

[Action]

A pick-up roller is disposed in the axial direction, a high friction coefficient member (for example, rubber) is disposed in a part of each roller, and a low friction coefficient member (for example, aluminum or plastic) is disposed in another part. When the high friction coefficient member of the pick-up roller comes into contact with the bill, the pick-up roller guide is not involved in the contact state, so the bill is reliably fed to the downstream separation point, but the low friction of the pick-up roller When the member rotates to the position where it contacts the bill, the pick-up roller guide contacts the bill, so that the low friction coefficient member of the pickup roller does not generate a conveying force to the bill. Thereby, the banknotes in the banknote group are 1
Sheets are fed one by one only at the timing of the high friction coefficient member portion of the pick-up roller, so that the banknotes are always fed to the downstream separation point at a stable cycle, and a good banknote transport state is obtained.
