Problems solved by technology

Then, the end E of the paper 10 facing the orifice portion 135 of the ink cartridge 130 will be in contact with the orifice portion 135, so that between the end of the paper 10 and the orifice portion 135, even if the image is printed required minimum spacing cannot be maintained
[0005] Therefore, it is also impossible to form an image on the end E of the paper 10 by inkjet, thereby causing a problem that the printable number on the paper 10 is limited by the end E of the paper 10

Embodiment Construction

[0037] Preferred embodiments of the invention will now be described in detail, examples of which are illustrated in the accompanying drawings, in which like reference numerals refer to like elements. The embodiments are described below in order to explain the present invention by referring to the figures.

[0038] Such as figure 2 As shown, according to the first preferred embodiment of the present invention, the paper discharge unit of the inkjet printer 200 includes a paper discharge roller 161 and a paper discharge guide member 210. When the front end of the paper 10 just comes out of the paper discharge roller 161, said The paper discharge guide member just guides the front end of the paper 10 upward.

[0039] The paper discharge roller 161 is installed downstream of the ink cartridge 130 in the paper discharge direction, and is driven by a driving unit so as to be rotatable forward and backward. Hereinafter, forward rotation of the discharge roller 161 refers to rotati...

Abstract

A paper discharge unit for an inkjet printer which ejects a sheet on which image printing is completed by an ink cartridge out of a printer main body. The paper discharge unit for an inkjet printer includes paper discharge rollers rotatably mounted in the printer main body to feed the printing-completed sheet out of the printer main body; and paper discharge guides disposed downstream of the paper discharge rollers in a direction the sheet is fed, and guiding upward the front end portion of the sheet ejected from the paper discharge rollers to prevent the rear end portion of the sheet from being lifted. Accordingly, the front end portion of the sheet is deformed by the paper discharge guides to restrain the end portion of the sheet facing a nozzle part of the ink cartridge from being in contact with the nozzle part when the sheet is ejected, so that image printing becomes possible up to the end portion of the sheet, to thereby improve the printing efficiency of the inkjet printer.

Description

technical field [0001] The present invention relates to an ink jet printer, and more particularly to a paper discharge unit that discharges paper on which an image has been printed by an ink cartridge out of a printer body. Background technique [0002] figure 1 It is a schematic diagram of a conventional inkjet printer. This conventional inkjet printer 100 has: a printer body 110 , an ink cartridge 130 , a paper pickup unit 140 , a paper delivery unit 150 , and a paper tray 120 . [0003] When the inkjet printer 100 having the above structure is driven, a paper 10 in the paper tray 120 is conveyed to the bottom of the ink cartridge 130 by a pickup roller 145 and the first conveying roller 151 and the second conveying roller 153 . In this case, if the paper 10 continues to be conveyed by the second conveying roller 151 so that the paper 10 leaves the second conveying roller 151 , the paper 10 will be output to the outside of the printer main body 100 by the discharge roller...
