Claims

[Scope of utility model registration request]

The paper is fed through a paper transport path formed between the upper and lower paper guide plates facing each other by a rotating roller, and the paper is detected by a paper detection sensor that inserts the paper into the transport path from above. In the paper detection device which detects paper by the contact of the lever with the paper, a flexible elastic plate is fixed at its rear end in the paper feeding direction to the lower or upper paper guide plate. Also, a paper detecting device, characterized in that the front end thereof is provided in the conveyance path so as to face a predetermined position of the upper end or the lower end of the detection lever in the conveyance path.
