Embodiment Construction

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0030] The inkjet printer 10 of this embodiment is as Figure 1 ~ Figure 3 As shown, it has a recording medium conveying device 20 , a printing device 30 , and a maintenance unit 40 . In this inkjet printer 10 , the printing device 30 prints predetermined characters on the recording medium M supplied from the recording medium conveying device 20 . The maintenance unit 40 performs cleaning of the print head 31 , filling of ink, and the like when the inkjet printer 10 is activated and a predetermined operation is performed by the user due to poor printing results. In addition, when the inkjet printer 10 finishes printing, the nozzle surface 34a is capped by the head maintenance device 42 of the maintenance unit 40 in order to prevent drying of the nozzle 34b and contamination of the nozzle surface 34a. Also, as the recording medium M, a film substrate, paper, ...

Abstract

The present invention provides an inkjet printer including a recording medium conveying device that conveys a recording medium, a printing device that prints the conveyed recording medium with ink ejected from a nozzle surface formed on a print head, A clean cleaning device (50), the cleaning device (50) has: a wiping blade portion (70) for wiping a nozzle surface with a wiping blade (75), and an ink absorber (61b, 62b) for absorbing the nozzle surface The roller wiping part (60) of the ink. With the cleaning device (50), the nozzle surface can be sufficiently cleaned, and good printing quality can be maintained.

Description

technical field [0001] The present invention relates to an inkjet printer equipped with a cleaning device. Background technique [0002] In an inkjet printer, in order to maintain good print quality, it is essential to have a cleaning device that cleans the nozzle surface of the print head. As a conventional cleaning device, there is an example in which a nozzle surface is wiped off by a plurality of wiping blades arranged on a belt as described in JP registered utility model No. 2543863 . [0003] Patent Document 1: JP Registration Utility Model No. 2543863 [0004] In the cleaning with the wiper blade as in the cleaning device described above, the nozzle surface of the print head having a fine nozzle diameter cannot be cleaned sufficiently, resulting in a decrease in print quality. Contents of the invention [0005] In order to solve the above-mentioned problems, the inkjet printer of the present invention is characterized in that it includes: a recording medium convey...
