Abstract

PURPOSE:To prevent use in a connection failure state, by providing a switch for opening or closing a circuit in accordance with whether a driving member and a driven member have been connected properly or not. CONSTITUTION:When an interchangeable lens 2 is set to a camera body 1 against springs 8, 15 and the interchangeable lens 2 is rotated, when a mount positioning hollowed part 64 of the interchangeable lens 2 reaches a position of a mount positioning member 9, a positioning part 10 of a positioning member 10 automatically goes into the hollowed part 64, and the interchangeable lens 2 is locked at a prescribed position against the camera body 1. In this case, a moving electrode 26 contacts with a fixed electrode 27, and the switch is turned on. When a motor 22 starts to rotate, the first driving shaft 13 is also rotated, and the moment when an engaging pawl 17 has aligned with a position of an engaging hollowed part 62, it becomes a normal meshed state by an action of the spring 15, and driving force is transmitted to the interchangeable lens side. Accordingly, use in a connection failure state is prevented.
