Abstract
PURPOSE: To make the position at which the tip end of wire reaches the face of paper constant, to improve the quality of picture and to perform the printing efficiently by proucing a voltage the value of which is proportional to the moving speed of the printing head and by making the solenoid driving current greater so much.
CONSTITUTION: The voltage VA' at the input point a of the operation amplifier OPA while the tachogenerator TG that detects the moving speed of head produces voltage is higher than the voltage VA at the input point a while the tachogenerator does not produce voltage by [R1/(R1+R2)].VTG. The voltage VB at the point d (b) by the solenoid current i increases with the moving speed of head. When the wire speed is varied by changing the value of current fed to the solenoid L so that the wire speed is VW1 and VW2 when the head speed is VH1 and VH2 respectively, both the composite vectors agree with each other on the same line, the shift of printing is prevented.
