Abstract
The disclosed camera sequentially controls the operations of two or more units, for example, an exposure control circuit and a film advance motor. An arrangement senses whether or not an operation has been completed normally and stores the result. When the succeeding operation is to start, the condition of the storage is sensed. If the memory indicates that the operation has not been normal, then the following operation is disabled.
