Abstract
A copying machine and paper supply cassette is provided with a control arrangement to prevent operation of the machine upon improper insertion of the cassette. A control switch mechanism for controlling the electricity supply to the copying machine includes a pivotable control lever having a first arm engageable with catch part of the cassette so that said cassette pivots said control lever as it is inserted into a cassette guide of the machine. The control lever includes a second arm engageable through a second opening in the sidewall of the cassette to permit the pivoting movement of the control lever. The opposite side of the cassette includes no second opening so that insertion of the cassette in an upside down position is prevented.
