PROBLEM TO BE SOLVED: To appropriately perform positioning of a strobe light emitting part even in repeated lens barrel operation of a camera. SOLUTION: Cam follower members 1a and 1b are provided in a slide lever member 1, corresponding to cam grooves 3a and 3b provided on a drive ring member 3 operating a photographic lens barrel 6. In a case where the cam groove 3a and the cam follower member 1a abut against each other first and the groove 3a and 1a are worn by repeated operation, the cam groove 3b and the cam follower member 1b contact each other next, whereby extreme positional deviation of the slide lever member 1 is prevented, and deviation of the slide lever member 1 is absorbed by a spring absorption mechanism of the stroboscope pop-up mechanism so as to move the strobe light-emitting part to an appropriate position.
