摘要：An operation member is moved from a first position to a third position via a second position. When the operation member is rotated from the second position to the third position, a plate portion integrally formed with the operation member pushes and rotates a changeover ring to rotate a stop changing plate and a shutter-speed changing plate. When the operation member is kept in the second position, the plate portion is not interlocked with the changeover ring. Thus, a stop and a shutter speed are not carelessly changed if the operation member is slightly rotated by a finger. Since the stop changing plate starts to rotate at a near portion of a rotational end of the changeover ring, the stop is substantially maintained in a smaller-stop state or in a larger-stop state even if the operation member stops on its way.
