ト式記録装置用目詰り防止装置。[Scope of Claim for Utility Model Registration] A clogging prevention device for an inkjet recording device that controls the direction of ink jump and performs printing, etc., which includes a timer pulse signal that turns on for a set time after a set time elapses. a clock generation circuit that also outputs a clock pulse signal when the timer pulse signal is being output; a sub-power supply for supplying power to each circuit when the main power supply stops; and the sub-power supply and the clock generation circuit. A synchronous power supply circuit that receives a timer pulse signal output from the circuit and outputs a synchronous voltage synchronized with the timer pulse signal from a sub power supply when the main power supply is not supplying power to each circuit, and an output from the synchronous power supply circuit. The system is equipped with a DC-DC converter that outputs a stable DC voltage in response to the synchronized voltage. A clogging prevention device for an inkjet type recording device, characterized in that it is capable of ejecting ink to prevent clogging of nozzles.
