Abstract
PURPOSE: To keep dot intervals constant and raise the quality of prints by a method in which the first control is given to make the speed of a DC motor lower at a time when printing is ended on the DC motor for driving carrier, and then the second control is given to stop the DC motor.
CONSTITUTION: When stopping a DC type space motor 8 for spacing a carrier 6 loading a printing head 5 in a serial printer, braking operation is made two-stepwise. In short, at a time when printing information is zeroed, the primary braking is made to lower the speed of the motor to a low speed at which quick stoppage is possible, the number of dot pulse from the zone pulse following the printing zone is started to count, and when the number of the dot pulse reahes a given value, the secondary braking is made to stop the motor completely. Thus, since the carrier 6 can be stopped near the middle point of the zone section 1, a suffiient preliminary running distance can be always secured regardless of the magnitude of viscosity, etc., in sliding portion.
