Claims

[Claims for Utility Model Registration] (1) An operating member that is provided on the outer wall of the camera and is operated from the outside and is moved relative to the camera body, and an operating member that is provided on the side facing the camera body of this operating member. , a light-emitting element that emits directional light; a detection means that is provided on the camera body and detects the amount and direction of movement of the operating member by receiving the light from the light-emitting element; and the light-emitting element and a light condensing means disposed between the light emitting element and the detecting means to refract the light of the light emitting element and projecting the light onto the detecting means, the surface of the detecting means relative to the amount of movement of the light emitting element. A camera operating device characterized in that the amount of movement of projected light is reduced. (2) An operating member provided on the outer wall of the camera that is operated from the outside and moved relative to the camera body, and an operating member provided on the side facing the camera body that emits directional light. a light-emitting element, and a detection means that is provided on the camera body and detects the amount and direction of movement of the operating member by receiving light from the light-emitting element, and the light-emitting element comprises: The light emitting element is configured to move on a curved surface having a focal point at a position farther than the distance between the light emitting element and the detection means, so that the amount of movement of the projected light to the surface of the detection means is smaller than the amount of movement of the light emitting element. A camera operating device characterized by:
