A recording apparatus having the above-mentioned "5" i-tilt nozzle head can perform image recording at a much higher speed than a recording apparatus having a single or a small number of nozzles. however,
Since the diameter of each nozzle (spout opening) of Kishu Heads is extremely small, it is easy for the nozzle to become clogged due to impurities in the ink, dryness, paper powder, dust in the air, etc. Since it has a large number of nozzles, cleaning or restoring its function is not easy.Furthermore, in the above-mentioned color recording devices, the amount of each color ink used varies depending on the type of color recording device. As a result, the liquid levels in each ink tank/- were uneven, which caused the ink pressure to fluctuate, resulting in deterioration of image quality.Furthermore, the inter-tank/- required a large volume. Therefore, it became an obstacle to effective use of space, and it was not possible to sufficiently reduce the size of the entire device.

[-16°] Next, the points regarding 1 ink tank / and / will be described. The ink E in each main tank λ passes through a communication pipe, enters into each corresponding sub-tank, is supplied to the recording head through an ink supply pipe, and is driven by driving pulses from the nozzles of the recording head. Discharge accordingly. At this time, since the ink E is mainly supplied by the siphon effect, the K that maintains the predetermined supply ink pressure is determined by the volume of the liquid level in each main tank λ/.
It is necessary to maintain the nozzle at a position a fixed distance @D downward from the lowest nozzle position corresponding to the lower surface of the wax on the Kikama head. However, since the amount of ink used differs for each color, if printing continues, the liquid levels in each main tank will become uneven through the sub-tanks. If left as is, each head γY.

7M, ? There will be a large difference in the ink ejection pressure for each BK and BK, making it impossible to obtain a faithful color tone. However, by positioning the angle coder at 1441 and adjusting the liquid level of each main tank J/ as shown in Figure 6. Such inconvenience can be easily solved by aligning the liquid level to a predetermined position. In addition, by providing a means for adjusting the height of one ink liquid level in this way, the recording head 7
Since the position of the liquid level is adjusted to 1111 degrees, the ink pressure can be kept constant without having to supply ink, so it is possible to easily obtain high-quality tooth material at all times.

Furthermore, the head cleaning machine is a 1-recovery system! Since the ink tank 2/ is placed in the empty space near the point 1170, the space can be used effectively and the overall size of the recording device can be downsized, and the number of parts for the ink tank support member required can be greatly reduced. It can also be reduced. Further, since the head cleaning unit #1170 and the ink tank unit 1 are located close to each other, there is an advantage that only one inspection port is required for maintenance and inspection. In addition, since the head cleaning mechanism 70 generates vibrations during operation, it is possible to apply vibrations to the #1 material type ink in the ink tank 1 to obtain a stirring effect.
