2. Description of the Related Art A recording apparatus having functions such as a printer, a copying machine, and a facsimile, or a recording apparatus used as an output device of a copying machine or a workstation including a computer or a word processor, etc., is based on a data signal. It is configured to record an image (including characters and symbols) on a recording material (recording medium) such as (OHP).

[0003] Such recording apparatuses can be classified into an ink jet type, a wire dot type, a thermal type, a thermal transfer type, a laser beam type and the like according to the recording type of the recording means used.

In a serial type recording apparatus that employs a recording method in which a main scanning is performed in a direction intersecting a conveying direction (sub-scanning direction) of a recording material, the recording material is set at a predetermined recording position, and then the recording material is set. The image is recorded (main scanning) by a recording means (recording head) mounted on a carriage that moves along the line, and after a recording of one line is completed, a predetermined amount of paper feeding (sub-scanning) is performed. Thereafter, the operation of recording (main scanning) the image of the next row is repeated, thereby performing image recording of the entire recording material.

On the other hand, in a line type recording apparatus which records only a sub-scan in which a recording material is fed in a conveying direction, the recording material is set at a predetermined recording position, and recording for one line is collectively performed. Thereafter, a predetermined amount of paper feed (pitch feed) is performed.
Further, by repeating the operation of collectively recording the next row, image recording is performed on the entire recording material.

Among these recording apparatuses, an ink jet type (ink jet recording apparatus) discharges ink from a plurality of discharge ports formed in a recording means (recording head) to a recording material based on a data signal to perform recording. Is what you do. Therefore, it is easy to make the recording means compact,
High-definition images can be recorded at high speed. In addition, it can be recorded on plain paper without special processing,
Running cost is low. Furthermore, since the non-impact method is used, there are advantages such as low noise and easy recording of a color image using multi-color inks.
