PURPOSE:To provide a photographing interlocking mechanism capable of performing a focusing operation at a higher speed and with higher accuracy and also capable of simplifying the mechanism itself and attaining the miniaturi zation of the entire camera by making the movable part provided with a film opening part of a camera main body light in weight, as for an FB drive system autofocus camera. CONSTITUTION:Just after a shutter is released, a motor fixed on the fixed part 3 of the camera main body starts to rotate, and the rotary driving force is transmitted to a lead screw 12 through a reduction gear group such as a gear 40, etc., and the movable part 2 of the camera main body, that is, a frame 19 is moved to a position of FB1. Then, a connecting mechanism constituted of a gear 21, etc., is connected with an output mechanism constituted of a gear 24, etc., for the movable part 2 of the camera main body, then, the rotary driving force of an A-drive system motor 17 is taken out as an A-drive output. Next, the frame is moved to a position FB2 in the same way, then, the rotary driving force of a B-drive system motor 37 is taken out as a B-drive output. |
