Patent ID: 8167301

Claim:
A paper sheet processing apparatus comprising: a housing part capable of housing a paper sheet which is inserted throw an opening narrower than the paper sheet; a pair of regulatory members which define both side edges of the opening; a presser plate which pushes the paper sheet to move through the opening into the housing part; a placing plate on which the paper sheet to be pressed by the presser plate is placed; a biasing member which biases the placing plate against the presser plate; a pair of contact faces which are disposed on both sides of the opening so as to oppose to the placing plate; and a motor which drives the presser plate wherein a moving speed of the presser plate is reduced in a vicinity of the opening by controlling the motor when the presser plate having been pushed out of the housing part moves into the opening, wherein the presser plate repeats a reciprocal movement passing through the opening such that a plurality of paper sheets are stacked between the placing plate and the pair of contact faces in the housing part, and the contact faces have a greater coefficient of friction as compared to a coefficient of friction between the paper sheets.
