Claims

[Scope of utility model registration request]

An autofocus camera that transmits a driving force for advancing and retracting a lens through a coupler on the body side that rotates about an axis parallel to the optical axis and is biased in a direction to protrude and connect to a mount surface, and the mount is connected to the body. An exchange used in an autofocus camera that can be attached to either an autofocus interchangeable lens that has a coupling hole on the lens side coupler that engages with the side coupler, or a non-autofocus interchangeable lens that has a coupling groove provided in the bayonet. In the lens attachment/detachment mechanism, a coupler that pivotally supports the body side coupler inside, is biased to protrude from the mount surface, and has a tip that engages with the inner periphery of the coupling hole of the autofocus interchangeable lens. a retraction lever that moves the fog cover holder in the retracting direction, a lens lock lever whose tip engages with a coupling groove of the non-autofocus interchangeable lens, and a lens lock lever that can be operated from outside the camera body. It consists of a retraction lever and a lens lock release button that moves the lens lock lever to the release side, and when the autofocus interchangeable lens is attached, the cover tip is inserted into the coupling hole of the mount. When the lens is locked and the non-autofocus interchangeable lens is attached, the key part of the lens lock lever engages with the coupling groove of the bayonet to lock it, and the lens lock release button is used to release any of the interchangeable lenses. A mechanism for attaching and detaching an interchangeable lens for an autofocus camera, characterized in that the lock can be released.
