The end of photographing with a lens-fitted photographic film unit is detected with a film winding finish display panel or a film sensing lever, and a photographing end signal 66 is inputted into IC 42 for forbidding charging to forbid charging operation of a stroboscopic device. In order to cancel this forbiddance, a prescribed temperature, acceleration or pressure corresponding to a temperature sensor, an acceleration sensor or a pressure sensor as a semiconductor sensor 63 set in the IC 42 is inputted and writing is permitted by a writing permission device 65. A prescribed electric signal is written from an input terminal 44 and compared with a set value in a set value storage unit 69 by a comparator 70, and only when the electric signal agrees with the set value, the forbiddance of charging operation of the stroboscopic device is canceled.
