It has an effect.

Description

Printer ejector {APPARATUS FOR EXITING OF PRINTER}

The present invention relates to an ejection apparatus of an inkjet printer, and more particularly, by adding an ejection guide to a paper printed through a micro ejection apparatus, a space in which ink can be dried on a preceding paper before ejecting paper after the preceding ejecting paper. The present invention relates to an ejecting apparatus of an inkjet printer, which prevents smearing of ink due to friction between a preceding ejecting sheet and a subsequent sheet.

Generally, in order to document data or files created by a computer by a user, they are printed using various printers.

Although various printers are used as such office printing machines, in the present invention, the internal pressure is increased by applying heat or pressure to the ink stored in the micro-injector, thereby generating bubbles, and by the bubbles generated at this time, An inkjet printer in which ink is ejected through a nozzle to form an image on a paper will be described by way of example.

The micro jet apparatus used in the ink jet printer includes a plurality of nozzles, and the resolution of an image formed by the ink jetted by the nozzle is about 300 to 1200 dots per inch (DPI), and the micro jet apparatus is installed in the ink jet printer. Therefore, color printing to form various colors is possible.

Accordingly, looking at the configuration of the inkjet printer according to the prior art, as shown in Figs. 1 and 2, a paper feeder 20 for supplying a paper (P) for printing, and the paper feeder 20 A feeding device 30 for feeding and feeding the paper from the paper; a printing device 40 for printing on the paper conveyed by the feeding device 30, and a paper printed by the printing device 40; The discharge device 50 and the printing device 40 is composed of a home position device 45 for capping or wiping after printing, all the devices (20, 30, 40, 45, 50) is a device The inside of the main body 10 is provided.

Referring to the operation of the inkjet printer having the above configuration in detail, the paper is loaded on the top of the knock-up plate 24 configured in the main frame 22 of the paper feeder 20, and the knock-up plate for picking up the paper. 24 is elastically supported by the knockup spring 26, and when the top sheet P1 is picked up by the pickup roller 28 provided above the knockup plate 24, the sheet 24 is cut into sheets by the paper separation pad 28a. Separated to be conveyed to the transfer device (30).

The paper P1 conveyed to the feeder 30 is interposed between the feed roller 32 and the feed auxiliary roller 34 in contact with the feed roller 32 at a predetermined pressure, and is printed by driving the feed roller. To the device 40.

When the paper P1 is transferred from the conveying device 30 to the printing device 40, the carrier driving motor M of the printing device 40 is driven and thus the belt B is driven, thereby providing a guide rail ( The image is formed on the upper side of the paper P1, which is fixed to 42 and moves left and right along the carrier shaft 44 and is conveyed from the feeder 30 through a nozzle provided in the micro injector 46.

Then, when the image is formed line by line on the sheet by the nozzle provided in the micro-injector 46 is moved to form a line on the sheet, and the image formed paper reaches the paper discharge device 50, the discharge roller An operation of discharging paper through the space between the 52 and the star wheel 54 is performed.

In other words, the paper conveying process of the inkjet printer is a paper feeder 20-> conveying device 30-> printing device 40-> the discharge device 50, the series of processes is completed, and the discharged paper is printed The printed surface on which the image is formed in the order of being discharged is placed on the outside of the printer with the upper side.

However, the stacking method of the ejecting device 50 of the inkjet printer according to the related art as described above is loaded in the order in which the stacked paper is discharged with the surface on which the image is formed upward as shown in FIG. And the ink of the paper P1 ejected first by friction with the paper P2 ejected before the ink of the first ejected substrate is completely dried as the next printing paper P2 is loaded onto the printing surface of the ejected paper P1. There is a problem that the phenomenon occurs.

The present invention has been devised to solve the above problems, by installing the discharge guide in the discharge device, by forming a place where the printing paper is dried and the place to be loaded, which is discharged later before the previously discharged printed material is dried The purpose is to avoid friction with the paper and to secure time for the previously discharged printing paper to dry.
