To downsize a body by building a gear train for transmitting a film wind-up drive into the body with saved space.

A cartridge loading chamber 29 is arranged on one side with a darkroom 28 in-between and a film take-up chamber 30 is arranged on the other side. A film advance 21 is arranged on the chamber 29, a finder optical system 15 on the darkroom 28 and a main capacitor 64 on the chamber 30, respectively. A plate is disposed across the upper side of the darkroom 28 from the chamber 29 to the top of the chamber 30. The gear train 42 is disposed to line up on the plate in order to transmit the rotational driving of the film advance 21 and a cap plate is attached on the plate to cover the gear train 42. The optical system 15, the main capacitor 64 and a stroboscope light emitting section 17 are attached on the cap plate.
