PURPOSE:To easily execute engaging/detaching and to make it difficult to take off a lens from a camera body while connecting them by setting a driving rotation transmitting shaft so that it can move between a position where a driving meshing part meshes with a follower meshing part and a position where they do not mesh with each other and energizing it to the position where they mesh with each other. CONSTITUTION:When an interchangeable lens 2 is pushed to a camera body by resisting the pressure of springs 8 and 15 and the interchangeable lens 2 is rotated, the interchangeable lens 2 is locked on a specified position in the camera body. At such a time, a movable electrode 26 contacts with a fixed electrode 27 so as to be in a state where a switch is on. When the motor 22 starts to rotate, a 1st driving shaft 13 starts to rotate. The instant the position of an engaging pawl 17 coincides with the position of an engaging recess part 62, they are automatically in a normal meshing state with the action of the spring 15 and a driving force is transmitted to the interchangeable lens side. An engaging hole 18 is fitted to a projection pin 63, of course, and the axial center of both transmitting shafts 13 and 60 coincide with each other. Thus, special engaging/detaching actions are not necessitated and said lens is not easily taken off because energizing force works to keep the connection in the midst of rotating. |
