The automatic original feeding unit 11 is arranged at the upper part of a main body of the image forming apparatus 1 in an openable-closeable way. The automatic original feeding unit 11 includes an original conveyance mechanism taking out originals from a paper feed tray one by one and conveying the originals to a paper discharge tray.
The automatic original feeding unit 11 conveys the originals to an original reading unit of the image reading unit 12 one by one by an original conveyance function. In addition, the automatic original feeding unit 11 can be also opened to bear the originals on an original board of the image reading unit 12.
The image reading unit 12 includes a carriage comprising an exposing lamp exposing the originals and a first reflecting mirror, a plurality of second reflecting mirrors acting in accordance with the action of the carriage, a lens block, and a CCD (Charge Coupled Device) of an image reading sensor.
The carriage is stationary at the original reading unit or is moved to and fro below the original board, so that the first reflecting mirror reflects the light of the exposing lamp, which is reflected by the originals. The plurality of second reflecting mirrors enable the lens block to reflect the reflected light of the first reflecting mirror. The lens block alters the scale factor of the reflected light and outputs the reflected light to the CCD. The CCD converts incident light into an electric signal and outputs the electric signal to the image forming unit 13 as an image signal.
