Abstract

PURPOSE: To shorten the time required for processing printing by a method wherein two point indicating element supporting bodies are made to conduct deceleration and acceleration simultaneously in the reverse direction to each other and thereby the vibrations of frame bodies are canceled mutually.
CONSTITUTION: When a motor 25 is electrified, a cam shaft 19 is rotated at a fixed speed. Accordingly, the 1st point indicating element supporting body 6 and the 2nd point indicating element supporting body 106 run along a stroke slightly longer than the pitch of arrangement of a point indicating element 15 at a fixed speed in the reverse direction to each other and perform a change of direction at positions opposite to each other. Since the same force of inertia acts on the 1st cam 20 and the 2nd cam 21 in the opposite directions to each other respectively, the cam shaft 19 is pressed to neither side and, therefore, the frame body and the main body are not vibrated. Next, either the point indicating element 15 of the 1st point indicating element supporting body 6 or the point indicating element 115 of the 2nd point indicating element supporting body 106 is driven in a selective manner appropriately according to a printing instruction, whereby a point is indicated at an optional position in a recording medium 1.
