Claims

[Scope of utility model registration request]

(1) In a camera that electromagnetically controls the movement of two types of members, a pair of upper and lower yokes, a permanent magnet held between the yokes, and the action of one of the yokes and the permanent magnet a first moving coil member disposed so as to cross the formed magnetic field; and a second movable coil member disposed so as to cross the magnetic field formed by the action of the other yoke and the permanent magnet. The first movable coil member operates by electromagnetic force to control the first type of member, and the second movable coil member operates by electromagnetic force to control the first type of member. What is claimed is: 1. A laminated structure of an electromagnetic actuator, characterized in that the operations of two types of members are controlled, and the yoke and the permanent magnet are used for controlling the two types of members.

(2) The electromagnetic actuator for a camera according to claim 1, wherein the two types of members are one of a shutter blade, an aperture blade, and an autofocus lens group. Laminated structure.
