Abstract
PURPOSE:To shorten moving distance between high speed moving state and stopped state, by holding a switching element necessary for short-circuiting a DC motor in ON state immediately after turning OFF of power source for a printer. CONSTITUTION:A control circuit for a DC motor in a serial printer comprises a DC power E source for driving, a bridge circuit constituted with driving transistors(Tr)1-4, diodes D1-D4 for auxiliary Tr5-6 and the like. Tr7-8 for holding circuit, a control power source D2 for holding circuit, an inverter IN, pull-up resistors R3-R6 and the like are additionally provided. When the power source for the printer is turned OFF, two Tr3-4 connected with one pole of the DC power source 2 are turned ON, and a short circuit is formed through any one of Tr selected in accordance with the rotary direction of DC motor and two diodes for the voltage produced through continuous rotation of DC motor, and brake operation is carried out through the short circuit current.
