Abstract

In order to provide an inkjet printer capable of suppressing the deterioration of the function of the head maintenance device and maintaining good printing quality over a long period of time, the present invention comprises a head maintenance device (42) as follows. That is to say, there are: elastic members (421a-421c) that push the end cap (420) toward the direction of pushing the print head (hereinafter referred to as the pushing direction); and at the central part of the end cap (420) in the longitudinal direction, An end cover seat plate (422) that supports the end cover (420) freely in the pressing direction.

Description

technical field [0001] The present invention relates to an inkjet printer equipped with a head maintenance device for removing ink adhering to a print head. Background technique [0002] In an inkjet printer, in order to maintain good printing quality, a head maintenance device for removing excess ink adhering to the nozzle surface of the print head is indispensable. An inkjet printer equipped with a head maintenance mechanism is disclosed in International Publication No. 05 / 037559 pamphlet. Furthermore, an inkjet printer equipped with an improved head maintenance mechanism is disclosed in, for example, Japanese Patent Application No. 2006-012288 (hereinafter, referred to as a prior application). [0003] Fig. 6 is a structural diagram of the nose maintenance device disclosed in the prior application, wherein (a) represents a top view, (b) represents a side sectional view, and (c) represents a side view. [0004] As shown in FIG. 6 , the nose maintenance device 42 includes...
