Line-dot recorder

Abstract

A line type dot recording device capable of solving the problem of low printing efficiency (printing time for one sheet) (long time) when a printing medium is moved by a rotating cylinder and an image is formed in a predetermined printing area by multi-way dot recording The problem is that it is possible to efficiently form high-quality images on a plurality of printing media. The line type dot recording device A comprises: as a recording head, a head (1) of a recording element having a plurality of ink ejection outlets (nozzles) in an inkjet system; The paper feeding mechanism (3) for feeding paper from the drum, the mounting and holding mechanism (4) for mounting and holding 4 sheets of paper on the drum, and the paper ejecting mechanism (5) for discharging paper are made by using 4-way multiplex in the sub-scanning direction. Dot recording is carried out in the road method, and the drum is rotated at 4 times the speed to form an image with 4 rotations, which can eliminate the problem of low printing efficiency and obtain high-quality images.

Description

technical field [0001] The present invention relates to a line dot recording device that efficiently prints on a printing medium (paper) mounted on the peripheral surface of a rotating body using inkjet recording dots in which recording elements composed of a plurality of ink ejection ports are arranged in a row. Background technique [0002] As a method of using an inkjet head to eject liquid droplets to form an image on a printing medium (paper), there is a serial printing method in which a carriage with a plurality of ink nozzles (ejection ports) is freely reciprocated. The recording head of the inkjet method moves and scans the inkjet head in the width direction (main scanning direction) of the paper (standard size) of the printing medium, while slightly advancing the paper in the orthogonal direction to record; the line printing method On the recording head of the inkjet method, the ink nozzles corresponding to one line of paper (one line) are arranged in a row, and the...

AI Technical Summary

Problems solved by technology

In this way, the rotating line-type recording heads are staggered, and a complicated mechanism is required to prevent the staggered line-type recording heads from colliding.

In addition, since a plurality of line recording heads 1 are rotated, there is a problem that a large space is required for rotation.

[0026] In addition, it is considered that in the above-mentioned inkjet printer, the ink is supplied by the ink cartridge mounted on the line recording head, but when using an external ink tank, it is expected that the piping from the external ink tank to the line recording head 1, etc. The number of line type recording heads 1 must be the same as there are many, so if the line type recording head 1 is rotated, there is a problem that it is also difficult to handle it.
