PURPOSE:To improve operability and mounting accuracy by moving interlocking members to the positions not engageable to the interlocking members of a camera body when mounting or dismounting an interchangeable lens, and moving the interlocking members to engageable positions when the mounting is completed. CONSTITUTION:The mount part 2 of a camera body 1 has a bayonet member 3, stop cam and stopping down interlocking levers 4, 5, and the mount part 11 of an interchangeable lens has a bayonet member 12, a reference ring 13, a body 14, a camera side holder 15 and a housing arm 16. These are so formed that the arm 16 moves to the position not engageable to the interlocking members of the camera body cooperatively with the pushing in of the interchangeable lens and that further its movement is locked by turning the interchangeable lens in a dismounting direction. Hence, the operability is improved by turning the lens barrel and the accuracy is maintained well by making the press-contact surface referred to a reference of the device only one set of the bayonet parts. |
