Problems solved by technology

[0005] However, if the downstream side end of the paper on which the print head is printing an image touches the print head when the roller that prevents heat transfer is in a pressed state, the following problem will occur, that is, vibration due to the impact at the time of contact Passed to the paper, and finally to the print head side, bands appear in the printed image being printed

Embodiment Construction

[0029] Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be mentioned that the following preferred embodiments are merely examples described in essence, and are not intended to limit the application, scope and use of the present invention.

[0030] figure 1 The appearance of the inkjet printer A according to the embodiment of the present invention is shown, figure 2 The internal structure of the inkjet printer A is shown to FIG. 7 . This inkjet printer A is used in a photo printing system. For example, in this inkjet printer A, image data is transmitted via a communication cable from a receiving module that acquires image data and performs necessary correction processing, etc., and prints on printing paper P1 and P2 based on the transmitted image data. This inkjet printer A is capable of performing automatic printing and manual paper printing. When performing automatic printing, pull out one end of the very long ...

Abstract

The invention discloses an inkjet printer, which comprises a compression type upstream paper roller(45) and a compression type downstream paper roller(46) respectively arranged at the upstream and downstream side of the drying unit(U6). The drying unit(U6) dries the printed papers(P1,P2) through rotation of the cams(86,87); the drying unit disengages the upstream paper roller after disengaging the downstream paper roller. Consequently, the printer can restrain heat transmission to the upstream side in the transmission direction of the drying unit while keep the downstream ends of papers in printing away from the printing head so as to prevent vibration.

Description

technical field [0001] The invention relates to an ink jet printer. Background technique [0002] So far, it is known that an inkjet printer that allows a printing head that ejects ink to move back and forth in the width direction of the paper to print is to print characters and images (hereinafter, the characters and images are simply referred to as "images"). s method. [0003] If the image-printed paper is stacked in the output tray before the ink is dry, the following problems will occur. Because the ink on the paper is not dried evenly, color defects will appear on the printed image. dots, or ink adheres to the back of the stack of paper. Therefore, it is necessary to allow the paper to dry sufficiently before stacking it in the paper output receiving tray. [0004] Japanese Laid-Open Patent Publication No. 2001-270089 discloses the following inkjet printer technology, which includes: an infrared heater that uses thermal energy to dry the ink falling on the paper on ...
