Title:
DRIVING METHOD FOR PAPER FEEDING PULSE MOTOR
Document Type and Number:
Japanese Patent JPS63207269
Kind Code:
A
Abstract:
PURPOSE:To prevent the phenomenon of white omission on a recorded image by dividing a heating body block group of thermal heads into two or more and generating a clock pulse, which drives a paper feeding pulse motor, in a first division and a last division to feed a paper. CONSTITUTION:When one line is divided into two or more, a first heating body block R1 is certainly used for the first division and the other heating body blocks are arbitrarily divided. The heating body block group is divided in this manner, and a first pulse 10 of the pulse motor driving clock are generat ed in first divisions A1, B1, and C1 of respective lines, and a second pulse 11 are generated in the last divisions A2, B3, and C7 of respective lines, and the paper is fed by d/2 twice per one line by two clock pulses. Thus, the phenom enon of white omission is prevented.
