PURPOSE:To surely control a flow rate of ink and improve a resolving power of a reproduced image by a method wherein an electronic signal having an image information is applied to an ink flow rate control unit to control a flow rate of ink. CONSTITUTION:A recording electronic signal having an image information is applied to an input terminal 40 of an ink jet control unit 28 installed between an ink pool 27 and an ink supplying port 15 of a spray gun 12 and it is converted into an electronic fluctuation of a moving coil 38. And in accordance with the fluctuation of this current, a coil 38 is made to perform a recipricating motion to control the displacement of a piston 32 which is constituted to be one body with the coil 38. Whereas, ink comes from the pool 27 and enters an ink chamber 29 then, passes through a space 32 between a cylinder 31 and a piston 30 which is controlled in accordance with an electronic signal having an image information, and further, it is induced to the supplying port 15 of the gun 12 via an ink conduit 33, attracted by a negative pressure generated by an air flow and is jetted out of an ink nozzle 16. |
