Abstract
The present invention provides an automatic paper feed apparatus which can reliably prevent papers from being discharged in an overlapped state in spite of simple construction. The automatic paper feed apparatus comprises a paper feed roller for automatically feeding a plurality of papers in order from an uppermost one, with the plurality of papers being contained in a cassette in a stacked state. A holding member having flexibility is provided so that the holding member comes into contact with the uppermost paper to generate a friction force that is weaker than that between the paper feed roller and the uppermost paper.
Claims19
An automatic paper feed apparatus comprising:
- a feed roller for automatically feeding papers, when the papers are contained in a cassette in a stacked state, in order from an uppermost one of the papers;
- and
- a flexible sheet constructed and arranged to be positioned on the uppermost one of the papers such that when said feed roller automatically feeds the uppermost one of the papers a friction force exists between said flexible sheet and the uppermost one of the papers, with
- (i) that component of the friction force resulting from said flexible sheet being generated solely from a weight of said flexible sheet and a coefficient of friction of a surface of said flexible sheet that contacts the uppermost one of the papers, and
- (ii) the friction force being weaker than a friction force existing between said feed roller and the uppermost one of the papers.
