Abstract
A feeding device comprises lateral and longitudinal feed position sensors for detecting that a rotatable cassette is placed in lateral or longitudinal feed positions, respectively, and a control device for controlling a cassette rotating motor based on the input from the lateral feed position sensor or the longitudinal feed position sensor, such that the longitudinal or lateral feed positions of the rotatable cassette and a fixed cassette differ. Accordingly, a situation can be avoided where the rotatable cassette and the fixed cassette that contain copy paper sheets of the same size are placed in the same longitudinal or lateral feed direction. The time can therefore be shortened for feeding the required amount of copy paper sheets in the apparatus to which the feeding device is attached. In addition, a rotation prohibition input device can be provided for inputting to the control device an instruction prohibiting the rotation of the rotatable cassette. The device is arranged such that the control device cancels the control to the cassette rotating motor in response to input from the rotation prohibition input device. Consequently, the time needed for feeding the required amount of copy paper sheets may be shortened. In addition, when the rotatable cassette and the fixed cassette contain copy paper sheets of the same size and are placed in the same longitudinal or lateral feed direction, a large amount of copy paper sheets can be supplied continuously when necessary.
