Abstract
An optical system driving device for a camera includes a displacement mechanism for actuating a photo-taking optical system by displacement; a driving mechanism arranged to alternately take first and second states, to shift the displacement mechanism to a first given degree in a given direction when the first state changes to the second state and to shift the displacement mechanism to a second given degree which is less than the first given degree when the second state a changes to the first state; first stopping mechanism for stopping the driving means in the first state; a second stopping mechanism for stopping the driving means in the second state and photographing means for performing photography under a condition that the driving means is stopped by the first and second stopping means.
