Problems solved by technology

However, when the bent ink tube comes into contact with the protective cap and floats up, it also becomes a resistance to the direction of movement of the print head
Moreover, sometimes it is necessary to attach positioning marking components such as coding strips near the moving range of the printing head along the moving direction of the printing head. Therefore, the bending of the ink tube must be limited within a certain range.
Even so, if special parts are provided to limit the bending of the ink tube, this alone will hinder the realization of miniaturization

Embodiment Construction

[0028] like figure 2 As shown, a paper feed roller 1 is provided at the rear of this inkjet printer, and the recording paper (recording medium) held in a stacked form on a paper feed tray (not shown) is separated and fed page by page. The recording paper sent out from the paper feed roller 1 passes through figure 1 The conveying roller 3 shown is conveyed to the platen 5 , and after the image is formed by the print head 7 , it is discharged into a paper discharge tray not shown by the paper discharge roller 9 .

[0029] as figure 1 A sectional view of line A-A of image 3 and as the image 3 Section view of line B-B of Figure 4 As shown, the print head 7 is mounted on a carriage 11, and the carriage 11 is movably guided in the width direction of the recording paper (main scanning direction) by a guide shaft 13 or the like. Furthermore, the carriage 11 is connected to an endless belt (endless belt) driven by a carriage motor 15 as a head moving mechanism, and moves the...

Abstract

The objective of the invention is to obtain an ink jet printer for forming an image by reciprocating a head in the widthwise direction of a recording medium and supplying ink to the head through a tube in which flexure of the tube is regulated without requiring an extra member and without imposing a large moving resistance to the head. When a head (7) moves together with a carriage (11), a tube (31) projecting from the end face of the head (7) in the moving direction flexes. Rearward flexure (leftward on the drawing) of the tube (31) is regulated by a tube band (41) abutting against the cover (25) of a carry roller (3) and a guide shaft (13). As shown on fig. 4, front end face of the cover (25) and front end face of the guide shaft (13) are disposed on a vertical plane perpendicular to a platen (5). Consequently, flexure of the tube (31) can be regulated without requiring an extra member and without imposing a moving resistance by floating the tube (31).

Description

[0001] This application is a divisional application of the application with the application number 02154598.7 and the title of the invention "ink-jet printer" submitted on December 10, 2002. technical field [0002] The present invention relates to an inkjet printer that ejects ink from a printing head and forms an image on a recording medium. Specifically, the printing head is made to reciprocate in the width direction of the recording medium, and at the same time, the ink is supplied to the printing head through an ink tube. A serial inkjet printer that forms images. Background technique [0003] Conventionally, it has been considered that in an inkjet printer, an ink holding unit for holding ink is provided separately from the print head, and ink is supplied from the ink holding unit to the print head through an ink tube. In this case, it is easier to reduce the size of the print head than to integrate the ink holding portion and the print head. Moreover, if such a struc...
