Electrographic apparatus

摘要

An electrographic apparatus comprising a main body, a manuscript discharge tray, a slit light exposure portion, a manuscript feed mechanism including upper and lower feed mechanisms, the upper feed mechanism being arranged movably with respect to the lower feed mechanism, a photosensitive body, a sheet manuscript edge guide, a thick manuscript edge guide and means for automatically changing the two edge guides in response to a movement of the upper feed mechanism with respect to the lower feed mechanism; the apparatus being constructed and arranged such that in the case of obtaining copies of a sheet manuscript the sheet manuscript is fed by the manuscript feed mechanism under a condition that the upper feed mechanism is mounted on the lower feed mechanism and scanned by exposed light by one time and in the case of obtaining copies of a thick manuscript a thick manuscript carriage on which is disposed the thick manuscript is fed by the lower feed mechanism under a condition that the upper feed mechanism is moved from the lower feed mechanism and scanned by exposed light by one time.
