Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink jet recording apparatus, and more particularly, to a print head of an ink jet recording apparatus.

[0002]

2. Description of the Related Art A print head of an ink jet recording apparatus is incorporated in a production line for use.

[0003] Ink-jet recording apparatuses use an electric wire for transmitting an electric signal from the main body of the apparatus to a print head, and ink and ink.
The connection cable containing the solvent flow path was attached to the base plate of the print head, connecting the main unit to the print head, and incorporating only the print head into the production line.

[0004]

As described above, the ink jet recording apparatus is used in a production line.

In some cases, the installation space is limited due to the rearrangement of the production line, and in a print head in which the connection cable is attached in the longitudinal direction of the print head base plate, an attempt is made to change the drawing direction of the connection cable. In such a case, the minimum bending radius of the protective coating that covers the outer periphery of the connection cable is limited, so that there may be cases where the protection coating cannot be incorporated into the production line.

[0006] An object of the present invention is to provide an ink jet recording apparatus having a print head which can be incorporated even in a limited narrow installation space.

[0007]

SUMMARY OF THE INVENTION The object of the present invention is to provide an ink jet recording apparatus for performing recording using ink droplets, in which an electric cable from an apparatus main body is transmitted to a print head, and a connection cable containing ink / solvent flow paths. This is achieved by providing means for changing the direction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a model diagram showing the configuration of a print head 100. A nozzle 2, a charging electrode 3, a deflecting electrode 4, and a gutter 5 are provided on a base plate 1, and a print head 10 is provided.
0 on the side of the print head 1
A hollow male screw 6 is provided for passing a connection cable 12 containing an electric wire and a flow path of ink / solvent to be transmitted to the outside.

The male screw 6 is screwed with a nut 11 for attaching a first rectangular connection flange 10 to the side surface of the print head 100. That is, on the side surface of the print head 100 through which the connection cable 12 penetrates, the first connection flange 10 for mounting the protective coating 13 covering the outer periphery of the connection cable 12 on the print head 100 side is attached. A second end screwed to the first connection flange 10 is provided at an end of the protective coating 13 on the print head 100 side.
Are connected. When the connecting cable 12 is pulled out in the same direction as the longitudinal direction of the print head base plate 1, the flat portions of the first and second connecting flanges 10 and 14 have the same pitch for screwing the two flanges 10 and 14. Screw holes 9 and 15 are provided, respectively. When the mounting direction of the connection cable 12 changes on the flat side surfaces of the first and second connection flanges 10 and 14,
Screw holes 7, 17 of the same pitch for screwing the flanges 10, 14 are provided respectively.

As a result, a print head 100 is formed in which the connection cable 12 is pulled out in the same direction as that of the conventional print head base plate 1 in the longitudinal direction.

FIG. 2 shows a case where the drawing direction of the connection cable 12 is changed.

The male screw 16 is removed and the second connection flange 1 is removed.
4 is removed from the first connection flange 10. Next, the male screw 16 is screwed into the screw holes 7 and 17 of the same pitch provided on the side surfaces of the flat plate of the first and second connection flanges 10 and 14, and the flanges 10 and 14 are attached. In this state, the first and second connection flanges 10, 1
Between the four, there is no protective coating 13 of the connection cable 12, the connection cable 12 is damaged by an external impact,
It is better to anticipate in advance that there may be a problem such as bending or bending. Therefore, a protection block 18 having a cable passage groove formed between the first and second connection flanges 10 and 14 is attached to the second connection flange 14 to protect the connection cable 12. Specifically, the male screw 20 is screwed into the screw holes 15 and 19 of the same pitch provided in the second connection flange 14 and the protection block 18 to screw the second connection flange 14 and the protection block 1.
8 is attached.

[0014]

According to the present invention, with respect to the limited print head installation space, the drawing direction of the connection cable containing the electric wire for transmitting the electric signal from the apparatus main body to the print head and the flow path of the ink and the solvent can be adjusted. In addition, it is possible to provide an ink jet recording apparatus having a print head that can be changed in a direction intersecting the longitudinal direction of the print head base plate and can be incorporated in a narrow installation space.
