摘要： PROBLEM TO BE SOLVED: To eliminate a difference in concentration in a wide reading device due to variation in paper by using a simple configuration.SOLUTION: In an image reading device, a plurality of CISs 3 are arranged in zigzag form to configure a reading unit in such a way that their end parts in the main scanning direction overlap in the sub-scanning direction. The image reading device includes: a level calculator 404 which extracts the signal level of a read signal in a section where the respective CISs 3 overlap every main scanning line; a gain calculator 405 which calculates a correction value with which to correct a read signal on one side of the respective read signals of two adjacent CISs 3 out of the plurality of CISs 3 arranged in zigzag form so that the extracted signal levels in the overlapping section of the respective read signals will become the same; and an effective region level corrector 403 which corrects a read signal on one side of the respective read signals of two adjacent CISs 3 on the basis of the calculated correction value.

摘要： PROBLEM TO BE SOLVED: To provide a facsimile device capable of transmitting an original document at a time in each appropriate size for every transmitting destination device even when the original document is transmitted to plural different destinations.
SOLUTION: The facsimile device comprises a scanner (15) for reading an image of an original document, an original size detecting unit (16) for detecting a size of the original document to be transmitted, a reduction processing unit (17) for reducing the size of the original document to be transmitted, an e-mail communication control unit (24) for controlling the image information to be transmitted via an e-mail through a computer network, and a destination device deciding unit (20) for deciding what the destination device is when the original document is transmitted via the e-mail. The facsimile device is designed to transmit the original document in an original size or in a reduced size reduced by the reduction processing unit (17) based on the detected size of the original document and the transmitting destination device when the original document is transmitted by the e-mail communication control unit (24).

摘要： PROBLEM TO BE SOLVED: To accurately and easily read only a region intended on a manuscript.SOLUTION: An image forming device 1 emits transmission light from a transmission light source 20 on a reading surface of a manuscript G placed on a placement surface 11a of an original platen 11 in a state that the reading surface faces a side of the placement surface 11a, specifies a reading range by a reading unit 13 of the manuscript G both within a placement range and outside the placement range of the manuscript G of the original platen 11 by reading position lines A3, A4 and makes adjustable a reading object region to be read by the reading unit 13 on the basis of an image of the reading surface projected on a surface opposite to the reading surface of the manuscript G by the transmission light source 20. When an operation part instructs and operates to start to read the manuscript G, conveyance rollers 14a, 14b, 15a, 15b convey the manuscript G on the original platen 11 to the reading unit 13.
