Abstract
To more fully utilize the surface area of a typewriter ribbon in a cartridge ribbon receptacle, the cartridge locating plate supporting the receptacle is caused to oscillate with respect to the print head assembly. The ribbon cartridge assembly is a part of a print head and ribbon carrier that is positionable along a line of print by a drive motor through a belt drive engaging a drive pulley rotatably mounted to the carrier. Mounted to rotate with the drive pulley is a cam that engages a cam follower also mounted to the head and ribbon carrier. An upstop forms a part of the cam follower and engages the cartridge locating plate. With the cam follower driven by the cam, an oscillating motion is imparted to the upstop with reference to the head and ribbon carrier which motion is then imparted to the cartridge locating plate. Also fastened to the head and ribbon carrier is a solenoid that when energized spring biases the cartridge locating plate through a leaf spring attached to the plate.
