ABSTRACT:
A sheet size detecting apparatus includes a rotary member for conveying a sheet rotation detector together with the rotary member for generating a pulse, a sheet size measurement control device including an arm provided in a vicinity of the rotary member to effect reciprocally rocking by the passing of the front end and the rear end of the sheet. The sheet size measurement control device measures the size of the sheet by counting pulses generated by the rotation detector means in response to the rocking of the arm and, adds a correction value to the measured sheet size according to the conveying speed of the sheet.
