发明名称 Camera system.
摘要 <p>A camera system comprises a camera body (1) and an optical accessory (10, 12) which are detachably coupled with each other through their mounts (2, 11) by rotating them around an optical axis relative to each other. Each of the camera body (1) and the optical accessory (10, 12) has a group of electric connection terminals (6). Each group is aligned approximately around the optical axis and arranged to come into contact with the other group when the mounts (2, 11) are coupled with each other by rotating them. The height in their contacting direction of each group of terminals (6) is arranged to have a stepped difference at least by one step. At least one of the two groups of connection terminals (6) is arranged to be movable in the contacting direction and to be elastically urged to move in that direction. Among each of said groups of connection terminals, a plurality of power supply connection terminals are disposed away from each other with other connection terminals which are provided for data communication disposed between the power supply terminals. The stepped difference is provided for one of the power supply terminals located in the rear of each group by setting back its height in the contacting direction from the height of all the communication terminals and that of the other power supply terminal.</p>
