Embodiment Construction

[0031] Implementation form one

[0032] figure 1 This is an external view showing an example of the structure of the image reading device according to the embodiment of the present invention, and a multifunction machine 100 is shown as an example of the image reading device. A multifunction machine (MFP: Multifunction Peripheral) 100 is composed of an MFP main unit 20 and an ADF (Auto Document Feeder, automatic document feeder) device 10 that automatically feeds a document when an image is read. The MFP main unit 20 performs Image reading, printing, fax sending and receiving, etc.

[0033] The operation panel 21 of the MFP main unit 20 is provided with an operation input unit 21a such as a start key and 0-9 numeric keys for the user to perform operation input, and a liquid crystal display unit 21b for outputting and displaying the working status to the user. For example, the user can designate either one of single-sided scanning and double-sided scanning of the document by p...

Abstract

The invention provides a scanning specifying unit, a first transportation path, a second transportation path, a path switching unit, and a document detection unit. The scanning specifying unit specifies any of a double sided scanning and a single sided scanning for a scanning method of a document. The first transportation path is a transportation path for double sided scanning for scanning a first surface and a second surface of the document in order. The second transportation path is a transportation path for single sided scanning, shorter than the first transportation path, for scanning the second surface of the document. The path switching unit selects any of the first transportation path and the second transportation path based on the specified scanning method. The document detection unit detects the document with the first surface scanned and the second surface not scanned when the double sided scanning is interrupted. The path switching unit selects the second transportation path for the transportation path of the first document in the resumed double sided scanning based on a detection result of the document detection unit.

Description

technical field [0001] The present invention relates to an image reading device and a document conveyance method, and more particularly, to an improvement of an image reading device that reads an unfinished document again when double-sided reading of the document is interrupted. Background technique [0002] Image reading devices capable of automatically feeding two or more originals and sequentially reading these originals are widely used. In addition, image reading devices capable of double-sided reading of documents by automatic feeding are also widely used. As for the image reading device capable of double-sided reading, we know the single-pass double-scanning method that uses two image sensors to read both sides of the original, and the original that is turned inside out during automatic conveyance, so that it can be read using one image sensor. Dual-path single-scanning method for double-sided reading of originals. [0003] In the double-sided reading of the dual-pat...
