Abstract

PURPOSE: To protect ununiform space between cross line of printing type and error operation of print selection by opposing rotation force transmitting elements adjacent each other through a washer and pinching a wheel part of a printing wheel between rotation force transmitting elements and the washer.
CONSTITUTION: Each cross line printing wheel 202 is supported by inserting loosely axial hole H into the outer periphery of a boss 2092 of a pawl (rotation force transmitting element) 209 disposed on each printing wheel axis 201 rotatably with the axis. Cross line pitch a of each cross line printing wheel is secured by width l of boss 2092 of the pawl 209 and thickness of a washer 210 inserted between pawls 209 of each cross line. A wheel part of the each printing wheel is pinched slightly between the pawl 209 and the washer 210. Movement of whole printing wheel along the axis 201 is controlled by a pair of engaging elements rigidly attached to the axis 201 on both sides of prints.
