ABSTRACT:
An electrostatic copying machine has a cassette detachment detection circuit. The detection circuit detects a detachment of any one of a plurality of cassettes. When one of the plurality of paper cassettes is taken out of the main body of the copying machine and returned to the original position by the detection circuit, the returned cassette is automatically selected for supplying papers therefrom. The residual of the papers of the cassette which is taken out of the main body is checked by a paper remainder detection circuit. In a case that, when the residual of the papers in the returned cassette is not a predetermined value, the operability of the copying machine can be improved since the cassette is returned to the main body and the paper is supplied from the returned cassette.
