IMAGE FORMING DEVICE, AUTOMATIC DOCUMENT CONVEYANCE DEVICE, AND IMAGE PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an image forming device having a configuration for utilizing a sheet loaded with an IC tag and capable of reducing error of an object to be outputted while reducing a user's burden to reduce cost.

SOLUTION: IC tag writers 91 and 92 are arranged in front of the device and on an innermost side of the device to detect at which angle in left upper, left lower, right upper, and right lower parts on a paper an IC tag 8 is positioned based on whether radiocommunication with the IC tag 8 on the paper is possible or not and its communication timing when the radiocommunication is possible and write information of the position in the IC tag 8. Since it is possible to know on which face of the paper an image using which direction as its top is formed from the information of the position, the information of the position is read from the IC tag 8 on a document and a position of the IC tag 8 on the document is detected in the automatic document conveyance device when using a paper after forming an image as the document to determine whether the document is properly set or not by comparing positions of the IC tag 8 in image forming and image reading.
