Problems solved by technology

However, the structure of Japanese Laid-Open Patent Application No. 9-300664 only allows fine movement of each nozzle head in the length direction of the nozzle head (nozzle row direction), so that when the nozzle head is inclined relative to the sub-scanning direction, it cannot be parallel to Move the nozzle head in the sub-scanning direction
Since the amount of fine movement in the sub-scanning direction must be calculated from the amount of movement caused by the fine adjustment bolt and the tilt angle of the nozzle head, the burden of data processing increases in obtaining the recording drive data and the tilt angle, which is very difficult. It is difficult to improve the accuracy of pattern formation
[0014] In addition, since the nozzle head returns to the sub-scanning direction in a parallel posture and then the position of the nozzle head in the sub-scanning direction must be fine-tuned, the operation of the fine-adjustment bolt becomes complicated

Abstract

First link members (56A and 56B), a pair of second link members (57A and 57B), and three head holders (51R, 51G, and 51B) are installed rotatably. Rotational pivots (50A and 50B) provided at intermediate portions of the second link members (57A and 57B) and a reference nozzle of the reference head holder (51R) are positioned on the same line in a main scanning direction. The reference head holder (51R) is rotated about the reference nozzle, and the other head holders (51G and 51B) are also rotated simultaneously. The head holders (51G and 51B) are formed to be movable parallel to a sub scanning direction, irrespective of the rotation angles thereof.

Description

technical field [0001] The present invention relates to a nozzle head holder, in particular to such a nozzle head holder, wherein the distance between the nozzles is adjustable in the sub-scanning direction, and the position of the nozzle head can be fine-tuned in the sub-scanning direction, and also relates to a device with such a nozzle head fixing device. droplet ejection pattern forming device. Background technique [0002] Recently, as inkjet printers of various structures are widely used, color inkjet printers capable of high-resolution color printing with photo quality have become popular. A plurality of nozzle heads are installed in the carriage of the inkjet printer, and each nozzle head has many (for example, 128) small nozzles, and these small nozzles form one or more rows in the sub-scanning direction. A desired image is recorded by ejecting ink droplets from each nozzle to form a dot matrix on the ejection target medium. Japanese Laid-Open Patent Application N...
