Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus having a printing mechanism for printing image information on paper, and particularly having high-speed and high-precision printing ability and suitable for an output information system such as a computer.

[0002]

2. Description of the Related Art Various information terminal devices have been developed to reflect the advanced information society, and image information recording devices which are peripheral devices thereof include, for example, a printer device, a copying device and a facsimile device. .

A conventional image information recording apparatus has a shuttle type recording technology in which a print head portion prints while reciprocating on a paper surface. In the shuttle-type recording technology, as shown in Fig. 5 of Nikkei Electronics (1976.4.19), the head stand equipped with a print head is reciprocally driven in conjunction with a spiral shaft driven by a stepping motor to print on plain paper. There is a structure to go. In addition to the spiral shaft, a belt or timing belt may be used to drive the print head unit. The printing timing and printing speed are adjusted and controlled by the drive of the stepping motor and the accuracy of the mechanism. This shuttle-type recording technology is advantageous in that the print head is small, lightweight, and inexpensive, but on the other hand, it takes a long time for scanning, and reciprocating motion causes unstable control at high speed due to inertial force of the spiral shaft. It has been well recognized that problems, belt stretchability, and in the case of timing belts, misalignment with toothed pulleys causes misalignment, which is a major obstacle for high-speed and high-precision printing. Was not done.

On the other hand, in order to cope with the advanced information technology, information terminal devices are required to have high efficiency, high accuracy, large capacity, and cost performance. Along with this, in particular, control and maintenance of the inkjet image information recording apparatus are required to be simple, highly efficient, and highly accurate.
On the other hand, the known example does not support such low cost, high efficiency, high precision mechanical control and reproduction of fine print data, and thus high definition color printing, high density information printing, user maintenance It does not correspond to the simplification.

Therefore, in order to solve these problems, a line print head system has been devised which does not require the print head to be moved by the shuttle. This is an ink jet printing method that employs a line print head in which ink ejection nozzles for the image density are arranged on a line in a direction perpendicular to the feeding direction of a recording medium, and each company has developed its own.
However, these line print heads are in the development stage of each company, and the maintenance method by the ink dry prevention and the cleaning operation at the time of installing the product has not been considered yet, and it has not reached the practical level.
