Abstract
A document sheet position detecting device adapted to for image forming apparatus, such as digital copiers and facsimile. Apparatus image information on an original document are optically detected using a CCD or other type line sensor and the detected optical signals are converted into electric signals which are fed to a printer or like recording apparatus to reproduce the images. The device detects positional data of the document sheet in a separate operation from the detection of the image read out operation. An optical filter may be inserted during the position detecting operation. The sensor is adjusted for the difference in intensity caused by the filter.
