Claims

[Scope of Claim for Utility Model Registration] (1) A driving source, a lens barrel mounting member that is equipped with a plurality of lens barrels and can move forward and backward in the optical axis direction,
a focus adjustment means that is connected to the drive source and includes a first transmission member that connects the drive source and the lens barrel mounting member and moves the lens barrel forward or backward according to the driving direction of the drive source; a second transmission member;
a switching member that can switch the lens barrel by interlocking the lens barrel mounting member in a direction perpendicular to the optical axis; a driving member that reciprocates in conjunction with the second transmission member; and a switching member that is integrated with the driving member. A lens barrel driving device comprising: a lens barrel switching means comprising an intermittent driving member that is driven and interlocks the switching member in a part of the reciprocating range of the driving member. (2) Utility model registration claim (1) characterized in that focus adjustment is performed at a position where the intermittent drive member is not interlocked with the switching member.
).The lens barrel drive device described in ). (3) The driving member is a fan-shaped gear, the intermittent driving member is an intermittent gear, and the switching member includes a gear that can mesh with the intermittent gear and a switching lever that is integrated with the gear. The lens barrel driving device according to claim (1) or (2) of the utility model registration claim.
