Abstract
A rotatable-cassette-type feeding device, for use in an image forming apparatus for forming images on sheets of paper, has a paper cassette for housing sheets of paper. This paper cassette can be rotated either to the longitudinal feeding station or to the lateral feeding station of the sheets of paper by a driving motor. The rotatable-cassette-type feeding device is provided with drive control means for controlling the driving motor in its rotation speed in such a manner that, during a state in which no copying process is required, the paper cassette is rotated at a speed that is lower than that marked during an copying operation. Thus, when the rotatable cassette is driven during the stand-by state, the motor is rotated at a low speed. Thus, it is possible to reduce noise that is generated from the driving system and the motor of the rotatable cassette, thereby making the device quieter.
