Abstract
PURPOSE: To make it possible to use a head driving circuit commonly, by turning on and off electric power supply to print heads of the dot printer having plural print heads alternately.
CONSTITUTION: In the print head driving circuit for ECR of the dot printer having plural print heads, the common line of the magnet coil of receipt print head 12 is connected to power source terminal 16 through transistor 14, and the common line of the magnet coil of journal print head 13 is connected to power source terminal 16 through transistor 15. Respective pring heads are selected to print by signals given to bases of transistors 14 and 15. Theerfore, magnet coil driving circuit 11 can be used commonly by both print heads. Diode 21 is provided for preventing the current from flowing reversely to heads which do not print.
