Abstract

PURPOSE: To facilitate exchange operation of a type wheel by a mechanism wherein a type wheel secured with the axis transmitting the motor driving force is attached removably in a radial direction of the axis for the printing unit whose type wheel is rotated with a motor.
CONSTITUTION: A boss 22 of a type wheel 2 comprises a pin 7 inserting hole 23 and a slot 24 which is provided to coincide the axis 4 with the center of the axis. The axis 4 is provided with a notch 41 wherein the point 71 of the pin 7 is inserted. The slot 24 is fitted at two sides of the axis 4 to mount the wheel 2 with the axis 4, inserting the pin 7 into the notch 41 of the axis 4, and rotating the pin 7 at 90° at the position fully inserted. The pin point 71 is fitted with the recessed notch 42 of the axis 4 to secure the wheel 2 firmly with the axis 4.
