Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an inkjet printer in an inkjet recording system.
[0002]
[Prior art]
In order to form a good image in an ink jet printer, it is necessary to supply a stable ink to the ink jet head, and to make sure that electric signals such as image data and control signals between the carriage and the ink jet head mounted on the carriage and the control board are accurate. It is necessary to communicate with Then, a plurality of inks of yellow (Y), magenta (M), cyan (C), and black (K) are supplied from the respective ink supply containers via the ink supply tubes to the inkjet head, and the carriage is controlled by the control substrate. The electric signal and the driving power are supplied by a plurality of cables such as a data signal line and a power supply line, and reciprocate in a reciprocating scanning direction based on information based on the electric signal to form an image.
[0003]
The reciprocating movement of the carriage makes rapid movements such as suddenly accelerating in one direction, suddenly stopping, or reversing the direction in a short period of time. You must always follow the movement. Therefore, the ink supply pipe and the cable are made of a flexible material so as to follow the reciprocating movement of the carriage.
[0004]
The inkjet head and carriage are connected to a plurality of linear members such as a plurality of ink supply pipes, data signal cables, and power supply cables.The carriage reciprocates with these linear members in a random state. When moved, these linear members become entangled with each other, or the cable is pulled by the moving carriage, thereby damaging the cable and making it impossible to form a smooth image. In order to prevent such a problem, in an ink-jet printer, “Image” is described in paragraph 0032 of JP-A-10-100440 (hereinafter referred to as Patent Document 1) and paragraph 0025 of JP-A-11-179886 (hereinafter referred to as Patent Document 2). The data is transmitted from the electric circuit of the recording device to the recording head by a flexible cable.``A flexible cable called a resin film printed with wiring patterns such as data signal lines and power lines is used. ing.

[Patent Document 2]
JP-A-11-179886 (see paragraph 0025)
[0007]
[Problems to be solved by the invention]
However, the above document does not focus on the binding state between the ink supply pipe and the flexible cable. As a member for binding the plurality of ink supply tubes and the cable into one, a band-shaped resin member called a cable tie or a binding band or a member called an iron wire-containing strap is actually bound. These members have a belt-like shape, and when the ink supply pipes and cables are bound by the belt-like members, it becomes very difficult to move the ink supply pipes and cables flexibly at the binding position when the carriage is reciprocated. This makes it difficult for the ink supply pipe and cable to follow the carriage.
[0008]
That is, since the ink supply pipe and the cable are in contact with the binding member at the binding position, their flexibility is impaired, and the ink supply pipe is bent so that stable ink supply cannot be performed, or the cable is broken and disconnected. Further, since stress is concentrated at the contact position, problems such as local deterioration and breakage of the ink supply pipe and disconnection of the cable occur.
[0009]
To solve such a problem, an attempt was made to bind the ink supply pipe and the cable using a tape instead of the binding member. However, unless the tape width was widened, a stable binding force could not be obtained, and the tape was damaged. Further, when the tape width is increased, the flexibility of the ink supply pipe and the cable is significantly impaired, so that it is impossible to accurately follow the carriage, and the supply pipe and the cable are damaged. Further, the adhesive used on the tape oozes out from the end of the tape with the passage of time, so that the adhesive adheres to the ink supply pipe and the cable and sticks, thereby affecting the maintenance of the apparatus.
[0010]
As described above, as a binding member that replaces the band-shaped binding member, the ink supply tube and the cable are damaged while maintaining the flexibility that the ink supply tube and the cable can accurately follow the movement of the carriage. Until now, no binding member has been found.
[0011]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and a binding member that allows an ink supply pipe and a cable to accurately follow the reciprocating movement of a carriage and that does not deteriorate or break these members at a binding position. It is an object of the present invention to provide an ink jet printer using the same.
[0012]
[Means for Solving the Problems]

[0013]
Therefore, by minimizing the contact area of the ink supply pipe and the cable with the binding member, these members can accurately follow the carriage, and even when image formation is repeated, these members are not untied.
