摘要：PURPOSE:To feed a sheet original while holding a thick original placing table at a home position by providing a sheet original conveying mechanism aside of the thick original platen. CONSTITUTION:When a reversible clutch 8 is switched to thin original mode, the driving force of a sprocket 10 is transmitted to a pinion gear 12 to feed out a rack 11, so the thick original placing table 2 starts moving forth and back along a guide rail 13. At this time, gear couples 24 and 33 of a sheet original conveying mechanism are dingaged immediately, so neither sheet conveying roll 21 nor 23' rotates. When the reversible clutch 8 is switched to sheet original mode, the motion of a driving chain 7 rotates two sheet original conveying rolls 21 and 23' through a unidirectional clutch 32 to nd a sheet original 19 in a direction B.
