Abstract:
The present invention is directed to providing an apparatus capable of transferring a sheet while reducing wear and using a relatively small driving force. The present invention is also directed to providing an apparatus capable of effectively obtaining a vacuum suction force with a simple structure. An apparatus 1 for transferring a sheet according to the present invention comprises a conveyer belt 30 provided with a plurality of vacuum suction holes 30c for allowing the belt member to vacuum-suck a sheet using an evacuation mechanism 12, a belt support member 8 having a plurality of evacuation passages 8c communicated with the vacuum suction holes, and a sheet support member 4 adapted to support the sheet in such a manner as to define an interspace between an uppermost region of an outer peripheral surface of the conveyer belt and a bottom surface of the sheet when the evacuation mechanism is in a deactivated state, whereby, when the evacuation mechanism is in an activated state, an air in the interspace S between the conveyer belt and the sheet D is evacuated from the vacuum suction holes and through the evacuation passages, so that the conveyer belt is displaced upwardly by a resulting vacuum suction force to transfer the sheet while vacuum-sucking the sheet.
