Claims

[Claims for Utility Model Registration] A camera body, a holding member that holds a lens and has a first helicoid carved around the optical axis of the lens, and a second helicoid that is threadedly engaged with the first helicoid. a rotating member that is threadedly engaged with the holding member via both helicoids and is supported by the camera body so as to be rotatable about the optical axis; one end of the rotating member is fixed to the camera body; a guide member extending from the part in the optical axis direction and provided on the inner peripheral side of the rotating member, converting rotational movement of the rotating member into rectilinear movement of the holding member in the optical axis direction; and the camera. a first electrical device supported by the main body; a second electrical device supported by the holding member; and a flexible substrate electrically connecting the first electrical device and the second electrical device; The flexible board has a fixed part fixed to the camera body, and a flexible part connected to the fixed part.
It includes an extended part connected to the flexible part and extended toward the inner circumferential side of the rotating member, and another fixed part connected to the extended part and fixed to the holding member, and the extended part is disposed between the rotation member and the guide member in contact with the guide member, and is capable of sliding on the guide member when the holding member moves straight, and the flexible portion An electrical signal transmission device for a camera housed in a housing provided on the outer circumferential side of a member, the housing being integrally formed with the camera body and sliding on both sides of the flexible substrate. 1. An electrical signal transmission device for a camera, characterized in that it has a contact surface that can be brought into contact.
