To provide a photographic film unit with lens in which a reset code for restoring photographing function can simply be inputted.

In a circuit board 31 constituting a stroboscopic device 23, a shutter switch 44 which turns on when a shutter button 9 is depressed and a knob switch 45 which turns on by receiving the pressure of a protrusion every time a winding knob 13 makes a turn are connected via a lead wire. A detection signal at the time when the switches 44, 45 turn on is inputted in a control IC 37 mounted in the circuit board 31. The control IC 37 restores the function of the stroboscopic device 23 when an input code inputted by operation of both the shutter switch 44 and the knob switch 45 coincides with a previously set reset code.
