Abstract:
A printer with an image reading device, comprising:a recording head driven in response to a recording signal;an image scanner attached with said recording head for reading image information recorded on a document;a reference plate arranged out of a recording region of said recording head so that before said image scanner starts reading the image information from said document, the surface concentration of said reference plate is sensed;a sheet feeding mechanism for transferring a recording sheet and for transferring the document read by said image scanner;control means for correcting a concentration of the image information of said document read out by said image scanner in response to a reading of the surface concentration information of said reference plate and for making a recording information,wherein, said control means performs both a concentration correction to compensate for non-coincidence in inclination of said document with respect to said reference plate and a correction of white nonuniformity caused by disturbance in a range of radiation of a light emitting member of said image scanner so as to make a recording information,and said recording head is driven with a recording signal based on the recording information so as to perform a recording on the recording sheet.
