发明名称 INK-JET RECORDING DEVICE
摘要 PURPOSE:To prevent the clogging of a printing head by jetting ink from corresponding nozzles on the occasion that the head reaches a prescribed position when a printing signal does not arrive within a prescribed time. CONSTITUTION:A signal from a printing signal generating circuit is amplified by amplifying circuits B1-B5 through the intermediary of OR gates G1-G5, whereby each of the electromechanical conversion elements 6-1-6-5 of the printing head 3 is driven. Meanwhile, the signal from the printing signal generating circuit A and a pulse signal from a reference pulse generating circuit C are inputted in control circuits D1-D5, which confirm the receipt of the signal E of position of the printing head and the arrival thereof at the prescribed position to the electromechanical conversion elements 6-1-6-5 receiving no printing signal within a prescribed time and deliver driving signals through the intermediary of the OR gates G1-G5 and the amplifying circuits B1-B5. Moreover, by the output of other driving signals of the control circuits D1-D5, a carriage moving signal F is delivered through the intermediary of the OR gate G, whereby the head 3 can be moved forcedly to a prescribed position.
