Claims

[Scope of utility model registration request]

(1) Electrical contacts are provided at opposing positions of the camera body mount and the lens mount that can be attached to the mount, and one of the electrical contacts is used to transmit a control signal instructing the shooting mode. The first electrical contact is recessed from the mount surface, and the first electrical contact is recessed from the mount surface.
The second electrical contact of the other mount, which faces the electrical contact of In a camera that regulates the operation of a control circuit within the camera body by separating the second electrical contact, a spring-biased member that assumes a retracted state and a protruded state corresponding to a protruded state and a retracted state of the second electrical contact, respectively. A camera mount having an electrical contact, characterized in that the second electrical contact is disposed in front of the second electrical contact in the rotational mounting direction of the lens on the other mount.

(2) The spring-biased member is located in front of the electric contact in the rotational direction of the lens in the other mount, as set forth in claim (1) of the utility model registration claim. Camera mount with electrical contacts.

(3) Utility model registration claim (1) characterized in that the spring-biased member assumes a retracted state and a spring-biased protruding state in response to the operation of the switching member.
A camera mount having an electrical contact according to item (2) or item (2).

(4) Any one of claims (1) to (3) for registering a utility model, wherein the spring-biased member is a bottle member having a brush-like round head. Camera mount with electrical contacts as described in section.
