ABSTRACT:
A camera which can be loaded with a cartridge for a recording medium with a recording portion is disclosed. The camera includes a processing circuit for reproducing at least recording data recorded in the recording portion. The camera further includes a detecting unit that detects a state of use of the recording medium independently from the data reproduced by the processing circuit. A control circuit is also provided. When the processing circuit cannot perform reproduction of the recording data, the control circuit restricts an operation of the camera on the basis of the state of use of the recording medium detected by the detecting unit.
