To simply display the completion of the preparation of photographing with strobe light.

When a main operation member 2 is moved to a photographing position, a light guide 10 is turned to a projecting position where its one end 10a projects on the upper part of a unit main body, and a photographic window 5 is opened. When the light guide 10 is at the projecting position, a stroboscopic switch 17 is turned on to start charging in a stroboscopic device. A winding detection switch turned on in response to the completion of winding by one frame is connected to a light emitting diode 18 emitting light when the charging completed in series. When winding by one frame is completed and the charging is completed, the light emitting diode 18 emits the light, which is projected to the outside through the light guide 10.
