Abstract

See full text

A control apparatus for a cam drive mechanism comprising a motor, a driven member having a cam follower, a rotatable cam which is rotated by the motor, and a cam surface on the cam, the cam surface including a pressing area which is inclined so as to press the cam follower against a load when the cam is rotated by the motor and a recessed area which is inclined in a direction opposite to the inclination direction of said pressing area. A controller rotates the cam by the motor in a single direction, and changes a rotational speed of the motor between when the cam is positioned at a first rotational position at which the recessed area and the cam follower face each other, and when the cam is positioned at a second rotational position at which the pressing area and the cam follower face each other.
