Abstract

In a printing mechanism in which the paper is to be moved through the mechanism by a rotating platen, it is necessary to connect a motor to the platen to cause the rotation. Conventionally, this has been done by affixing the motor rigidly to the frame and, either by direct connection or through gears or belts, transferring the rotation of the motor to the platen.

Platen Drive Mechanism

In a printing mechanism in which the paper is to be moved through the mechanism by a rotating platen, it is necessary to connect a motor to the platen to cause the rotation. Conventionally, this has been done by affixing the motor rigidly to the frame and, either by direct connection or through gears or belts, transferring the rotation of the motor to the platen.

The figure shows the improved technique in which a motor 10 is suspended from the platen shaft 12 and fastened thereto by a cotter pin 14 through both engaged shafts. A stationary standoff 16 is further connected to the Motor 10 to prevent motor rotation. As the motor shaft 18 rotates in, for instance, the counterclockwise direction, the motor body is torqued clockwise against the standoff 16, forcing the platen 20 in the motor shaft direction. The assembly shown in the figure greatly simplifies the paper feed path through the printing assembly.
