Claims (1)

[Claims for Utility Model Registration] An image sensor unit that converts image information of a document into an electrical signal and outputs it, a storage unit that encodes this electrical signal and stores it line by line, and a storage unit that encodes the electrical signal and stores it line by line. In an image forming apparatus consisting of a signal processing section consisting of a reading means that serially reads out the image signal, and a recording section that receives the read image signal and prints it on recording paper, it is possible to decide whether to make a normal image or a mirror image at the time of recording. Selection means for selection, respective or shared address signal circuits for the normal image and mirror image in the readout means, and address signal circuits for the normal image and mirror image in the readout means if the storage means is not configured with 1 byte and 1 bit; Alternatively, an image forming apparatus characterized in that it is provided with a parallel/serial conversion circuit according to the number of bits constituting the shared storage means.
