Claims

[Claims for Utility Model Registration] (1) A motor capable of forward and reverse rotation as a driving source, a reduction gear train connected to the motor, a sun gear located at the final stage of the gear train, and a sun gear located at the final stage of the gear train. A planetary gear that meshes with the planetary gear, a switching cam unit that rotates integrally with the planetary gear and moves the light emitting unit component to switch the light distribution speed according to the focal length of the photographing lens, and a pivoting support for the sun gear and the planetary gear. A friction mechanism is arranged between the sun gear and the planetary carrier, which is fixed to a movable case, a stopper that stops the planetary carrier in its raised position, a front panel, a reflector, and an arc tube. A flash device comprising: a movable case having a light emitting component. (2) A position detection member provided on one side of the planetary carrier, movable case, or main body case, and a position detection board fixed to the other side,
2. The flashing device according to claim 1, further comprising a motor. (3) Either one of the light distribution position detection board or the detection contact member that rotates together with the planetary gear, and the other of the board or member fixed to the movable case that contacts one of the board or member. 2. The flash device according to claim 1, wherein switching of the light emitting unit components is controlled based on the focal length of the photographing lens.
