Abstract
A printing apparatus in which a cam member is connected to a type wheel by means of a rotating shaft so that the cam member rotates in a body with the wheel. The wheel is rotated by means of a motor for type selection. A pair of ribbon vibrators for supporting a correction ribbon are connected to the cam member by means of an operating plate attached to one of the vibrators. As the cam member rotates, a cam follower pin at the distal end portion of the operating plate alternatively engages one of first, second, and third cam portions formed on the cam member. In a normal printing operation, the correction ribbon is held in a nonprinting position, with the cam follower pin in the third cam portion, while the cam member is rotating in one direction. When the cam member rotates in the other direction, the pin is moved to the second cam portion via the first cam portion, so that the correction ribbon is held in a printing position. In this state, type selection and print correction are performed.
