Claims

[Scope of utility model registration request]

A photo star lamp that has a light emitting part and a light receiving part for a series of multiple openings provided in the shutter blade that also serves as an aperture? The position of the shutter blade is detected from the output of the photointerrupter, which is generated by installing the shutter blades in close proximity and having the plurality of apertures sequentially intermittent light entering the light-receiving unit from the light-emitting unit as the shutter blade moves. A strobe photography synchronization device that performs automatic flash photography by controlling the timing of strobe light emission according to the strobe light emission timing, characterized in that the installation position of the photo ink clubter in the moving direction of the plurality of openings is adjustable. Photography synchronization device.
