To take a stroboscopic photograph of a moving subject with natural description although constitution is simple.

With a shutter button 18 pressed, a rod type lever 65 moves down, a lock lever part 58 comes out of a flank of a projection 63a, and a rotary lever 57 is rotated clockwise. Shutter blades 51 and 52 are being opened and a rod type projection 60a is pressing a contact piece 37a up. The shutter blades 51 and 52 are fully opened and the contact piece 37a is disengaged from the rod type projection 60a and made to abut against a rod type projection 60b. An unlock lever part 59 pushes a lock lever 72, a shutter set lever 71 is unlocked to rotate clockwise, and a rotary lever 57 is rotated counterclockwise. In the middle of the closure of the shutter blades 51 and 52, the rod type projection 60a pushes the contact piece 37a up to contact a contact piece 37b and a synchro shutter 37 is turned on to carry out stroboscopic light emission. Then the shutter blades 51 and 52 are completely closed.
