用している。[Embodiment] FIG. 1 is a schematic overall configuration diagram showing an example of an ink jet recording apparatus of the present invention. The recording head 5 is guided by the carriage guide 6 to move in the direction of arrow I, and ink jet recording is performed on the recording paper 3 which is fed by intermittent line feed in synchronization with the recording head 5 by the platen 1 and the guide roller 4. The recording head 5 is provided with a plurality of ink ejection ports (not shown), and a dot image is formed on the recording paper 3 by ink ejection means such as piezoelectric element control, electric field control, and charge control. The recording head 5 of this example has nine ink ejection ports in a row at a pitch of 0.635 mm and ejects ink droplets having a diameter of about 120 μm. The ink material used is an aqueous ink in which 10 to 20% glycerin and 1 to 2% dye are dissolved in water.

汚れを防止している。Further, the recording paper 3 is preheated and heated to 100 to 130 ° C. before and after inkjet recording by the heating element 2 composed of a heating resistor of 100 V and 80 W on the surface of the platen 1, and the recording ink recorded by the inkjet recording is rapidly It is dried to prevent unnecessary bleeding, paper wrinkles, and stains due to unfixed ink.

りを防止できるものである。A return spring is placed between the recording head 5 and the frame 7.
13 operates, and the recording head 5 is always pulled toward the paper feed motor 9 side. This return spring 9 allows the carriage motor 12 to be circuit-free in a stopped state or a standby state where inkjet recording is not performed, the recording head 5 moves to the paper feed motor 9 side, and at a position not facing the heating element 2. It will stop. Therefore, the ink ejection port does not face the heating element 2 except in the ink jet recording state, and clogging caused by solidification of the ink due to heating can be prevented.

させるようにしてある。In the above-described embodiment, the recording head 5 is moved to the outside of the heating area by the mechanical action of the return spring 13, but it is also possible to electrically control the carriage motor 12. Specifically, in FIG. 2, when the control circuit 14 determines that the recording head 5 is stopped or in the standby state, the carriage motor 12 is operated to move the recording head 5 to a position not facing the heating element 2. It is a thing. When the main power supply 15 is turned off for some reason, the auxiliary power supply 16 causes the recording head 5 to move.
