Sheet supply apparatus

Abstract

A sheet supply apparatus includes: an endless belt which has a plurality of vents penetrating from a front surface to a rear surface and is stretched around a plurality of rollers including a drive roller and driven by the drive roller; a suction section having a suction port which suctions air and faces to a rear surface of the belt, wherein the sheet supply apparatus suctions a sheet to the front surface of the belt through vents of the belt facing to the suction port and carries the sheet, and the sheet supply apparatus further includes a guide member which guides a leading edge of the sheet being conveyed to a down stream side of the suction port in a conveyance direction, in a direction separating from the front surface of the belt.

1 . A sheet supply apparatus comprising:
 an endless belt which has a plurality of vents penetrating from a front surface to a rear surface and is stretched around a plurality of rollers including a drive roller and driven by the drive roller;   a suction section including a suction port which suctions air and faces a rear surface of the belt,   wherein the sheet supply apparatus suctions a sheet to the front surface of the belt through vents of the belt facing the suction port and carries the sheet, and the sheet supply apparatus further comprises a guide member which guides a leading edge of the sheet being conveyed to a down stream side of the suction port in a conveyance direction, in a direction separating from the front surface of the belt.   
     
     
         2 . The sheet supply apparatus of  claim 1 , wherein the guide member is disposed along a side surface of the belt and includes an inclined portion which guide the sheet being conveyed in the direction where the sheet is separated from the front surface of the belt. 
     
     
         3 . The sheet supply apparatus of  claim 2 , wherein the guide member is disposed such that the incline portion stretches from the front surface of the belt when viewing the side surface of the belt. 
     
     
         4 . The sheet supply apparatus of  claim 2 , wherein the guide member is disposed such that the incline portion crosses with the front surface of the belt when viewing the side surface of the belt. 
     
     
         5 . An image forming system comprising an image forming apparatus and a sheet supply apparatus which comprises:
 an endless belt which has a plurality of vents penetrating from a front surface to a rear surface and is stretched around a plurality of rollers including a drive roller and driven by the drive roller;   a suction section having a suction port which suctions air and faces to a rear surface of the belt,   wherein the sheet supply apparatus suctions a sheet to the front surface of the belt through vents of the belt facing to the suction port and carries the sheet, and the sheet supply apparatus further comprises a guide member which guides a leading edge of the sheet being conveyed to a down stream side of the suction port in a conveyance direction in a direction separating from the front surface of the belt.
