Abstract
An electromagnetic driving apparatus includes a magnet member having a first face in which first and second magnetic poles are formed in a first direction and a second face in which the first and second magnetic poles are formed in a second direction, a first coil facing the first face, a second coil facing the second face, a first member holding the magnet member, and a second member holding the first and second coils. One of the first and second members holds a driven member. The first and second members are relatively moved in the first direction by the energization of the first coil, and the first and second members are relatively moved in the second direction by the energization of the second coil. The actuator constituted by the first and second coils and the magnet member can be compactly arranged in one region in the apparatus.
