ABSTRACT:
In an optical scanning type system, a laser beam emitted from a laser generator is directed to a mirror which is fixed on a movable pedestal. The laser beam reflected from the mirror is converged on the end face of one of an array of optical fibers by a convergent lens which is also fixed on the movable pedestal. A cam follower is fixed to the pedestal and caused to contact a cam surface of a cylindrical cam body, which defines a number of steps having a stepwise varying height and formed so as to have a predetermined pitch. The cylindrical cam body is coupled to a step motor. The optical fibers are located so as to arrange the end faces thereof at a pitch corresponding to the pitch of the steps. The cylindrical cam body is stepwisely driven so that the cam follower also stepwisely follows the cam surface. Thus, the pedestal is stepwisely shifted and the laser beam is also stepwisely introduced into the optical fibers.
