摘要 An object of the present invention is to provide a camera capable of exactly displaying the number of residual films, even if there is concerned with such a situation that at the time when layered films remain in a film pack, the rear cover is opened and the film pack is re-mounted. The operational amplifier 236 is used to detect a current IM conducting through the feeding motor 214, and the detected current is subjected to the AD conversion by the MPU 220. The display unit 61 displays a predetermined number corresponding to the number of films layered within the film pack having the shielding plate, or a number in which one is subtracted from the number of residual films stored in the storage section 210, according as it is detected that now discharged one is the shielding plate.
