Abstract
There is disclosed a camera in which a power for a pop-up action of a built-in strobe is branched and taken out from & barrel-driving power transmitting path, the barrel is popped up in synchronization with an advancing action of the barrel from a retracted position to a shooting position, and a driving source for the barrel and a driving source for the strobe are from a common source. A first interrupting gear and a second interrupting gear are disposed coaxially and mutually movably in an intermediate portion of the barrel gear train. A following spring is interposed between the first interrupting gear and the second interrupting gear. The first interrupting gear idles in a predetermined range with respect to the second interrupting gear. A lock lever and a lock portion are made such that they can be engaged with and disengaged from each other. The lock lever and the lock portion are engaged with each other when the strobe is popped up by the upward movement of a rack, thereby preventing the strobe from moving in a pop-down direction. The following spring accumulates energy by the turning movement of the first interrupting gear in the pop-down direction, and, when the first inter…
