メラ。 In a retractable camera with a structure in which the barrier opens and closes in front of the stored lens barrel, the lens barrel is driven by a motor and is screwed onto a screw rod extending in the direction of the optical axis, and moved by the rotation of the screw rod. In addition to providing an interlocking member that drives the barrel in the optical axis direction, this interlocking member has a small non-interlocking area that does not drive the linking part of the lens barrel, and furthermore, a non-interlocking area that does not drive the linking part of the lens barrel. A collapsible camera characterized by comprising a barrier drive mechanism that opens and closes the barrier in conjunction with the interlocking member that moves according to the movement of the barrier.
