ABSTRACT:
An operation control device is provided in an electro-developing type camera using a recording medium which electronically develops an image formed by a photographing optical system. An electric charge in a battery is sensed. When the electric charge remaining in the battery is lower than a second threshold value, which is lower than a first threshold value, the recording operation is prohibited. When the electric charge remaining in the battery is lower than the first threshold value and higher than the second threshold value, the recording operation is permitted and the reading operation is prohibited. Accordingly, during the reading operation, the electric charge remaining in the battery cannot become lower than the first threshold value, and thus the reading operation can be carried out.
