Abstract

PURPOSE: To enable to perform the drive of head correctly, without using expensive pulse motor, by providing two nails turned unidirectionally for the latchet, at the operation of solenoid corresponded among two solenoids.
CONSTITUTION: The magnetic head moves on the guide rod along the groove provided on the cam. When the cam is turned clockwise, the solenoid 13 is driven, the plunger 12 is attracted, and the lever 6 is moved. In this case, the nail 4 causes turning by taking the pin 6' as the axis while gearing with the latchet 2. When the drive of the solenoid 13 is stopped when the movement by one teeth's share is finished, the plunger 12 and the lever 6 return to the original position, and the nail 4 ungeared with the latchet 2 and the next signal is waited. Further, the cam is turned counterclockwise, then the similar operation is obtained by driving the solenoid of opposite side.
