Claims

[Scope of utility model registration request]

(1) By detecting that the subject brightness is lower than a predetermined value, the strobe light emitting part pops up and switches to strobe photography, or the light emitting part always pops up and For cameras with a built-in strobe that sometimes charge and fire automatically for flash photography, there are three positions: the low-brightness automatic flash mode position located in the center, and the daytime sync mode position and flash stop mode position located on each side of this position. a strobe mode switching operation member that is displaced; a spring that urges the strobe mode switching operation member to remain at a low brightness automatic light emission mode position;
a locking member that locks the strobe mode switching operation member in a daytime sync mode position or a light emission stop mode position, and that releases the locking in conjunction with the strobe light emitting unit being displaced to a storage position; A strobe switching device characterized by:

(2) The strobe mode switching operation member has a protrusion formed approximately at the center of the back surface thereof, and the locking member has two locking grooves formed on the front surface of the upper part into which the protrusions fit; The strobe mode switching device according to claim 1, wherein the protrusion and the locking groove move in the direction of engagement and disengagement.

(3) The locking member is biased by a spring in the direction in which the protrusion and the locking groove fit together, and is pushed by a portion of the locking member when the strobe light emitting section is displaced to the storage position, resisting the spring. The strobe mode switching device according to claim 2, characterized in that the strobe mode switching device moves as follows.
