To easily switch an electronic flash light emitting mode.

A film unit with a lens 10 in which various photographic mechanisms and a stroboscopic device are assembled is provided with a stroboscope operation lever 17 operated to be switched between a 1st set position 17a, a 2nd set position 17b and a 3rd set position 17c. When photographing is performed after switching the lever 17 to the 1st set position 17a, a mode is switched to a forcible light emitting mode in which a photometric window 18 is covered with a mask part 19 integrally integrally formed with the lever 17 and electronic flash light emission is always performed, and when photographing is performed after switching the lever 17 to the 2nd set position 17b, the mode is switched to an automatic low luminance light emitting mode in which the electronic flash light emission is performed when the brightness of peripheral light from the window 18 is equal to or under a specified level, and when photographing is performed after switching the lever 17 to the 3rd set position 17c, the mode is switched to a light emission inhibiting mode in which the electronic flash light emission is inhibited and the charge of the stroboscope is stopped.
