Problems solved by technology

[0004] First, since the scanning unit 3 and the document D move in the main scanning direction M and the sub-scanning direction S respectively, it is difficult to maintain high scanning accuracy when reading an image from the document D
[0005] Second, since the feeding unit 4 is generally designed to feed the paper P, the paper P and the document D have a limit to the allowable thickness of the correct feeding
In particular, since the process of copying a color image requires a greater amount of image information, it often requires a huge memory, thereby increasing the cost of the image input / output device

Embodiment Construction

[0034] The present invention will now be described more fully with reference to the accompanying drawings, in which several exemplary embodiments of the invention are shown.

[0035] figure 2 is a cross-sectional view of an image input / output device according to an embodiment of the present invention. refer to figure 2 , the image input / output device includes a transparent document support 10 on which a document D is loaded, a platen 20 on which a paper P is loaded, and an image input / output module 50 . The document supporter 10 and the deck 20 are disposed parallel to each other, and the image input / output module 50 is disposed between the document supporter 10 and the deck 20 . The image input / output module 50 includes an inkjet head 30 that ejects ink to a paper P to print an image, and a scanning unit 40 that reads image information from a document D. As shown in FIG. The scanning unit 40 and the inkjet head 30 face opposite directions.

Abstract

The invention discloses an image input / output module, an image input / output device and the related method. The image input / output device comprises a document supporting piece on which the document is supported, a bedplate arranged in parallel with the document supporting piece and used to bear the document, and an image input / output module which is arranged between the document supporting piece and the bedplate and makes movement in the sub-scanning direction. The image input / output module comprises an array ink-jet head and a scanning unit used for reading image information from the document; the array ink-jet head comprises a nozzle unit with the length corresponding to the width of the paper.

Description

technical field [0001] The invention relates to an image input / output module, an image input / output device and a using method thereof. In particular, the present invention relates to an image input / output module using an array inkjet head as an output module, and an image input / output device and method of use thereof. Background technique [0002] figure 1 is a schematic perspective view of a conventional image input / output device. refer to figure 1 , the reciprocating inkjet head 2 and the scanning unit 3 are installed on the carriage 1 that reciprocates in the main scanning direction M. Sheets P and documents D are fed by the common feeding unit 4 along a common feeding path. If an image is input from a document D, the feeding unit 4 feeds the document D in the sub-scanning direction S. As shown in FIG. The scanning unit 3 reads an image from the document D while the carriage 1 reciprocates in the main scanning direction M. As shown in FIG. If an image is to be print...
