Sheet conveying apparatus and original document processing apparatus

An original document processing apparatus comprising:

• conveying means for conveying an original document to an original document reading position;
• a pair of reverse-discharge rotating members capable of rotating forward and reverse for feeding the original document to said conveying means by switchback, and discharging the original document conveyed from said conveying means;
• and
• electricity removal means for removing electricity from the conveyed sheet;
• wherein the switchback serves to feed an original document from said pair of reverse-discharge rotating members to the conveying means;
• and
• wherein the electricity removal means is disposed at a downstream side in an original document discharging direction from a cross over position for a front edge of the original document and a rear edge of the original document in a case of conveying the original document having a maximum conveyable length by switcbback, and at a downstream side in the original document discharging direction of said pair of reverse-discharge rotating members and a back edge of said original document, when said original document is passed through said original document reading position in an upside-down manner, in a case where said original document subject of being conveyed by said original document processing apparatus of a maximum conveyable length.

A sheet conveying apparatus comprising:

• conveyor for conveying a sheet to a prescribed position;
• a pair of reverse-discharge rotating members capable of rotating forward and reverse for feeding the sheet to said conveyor by switchback, and discharging the sheet conveyed from said conveyor;
• and
• electricity removal unit for removing electricity from the conveyed sheet;
• wherein the switchback serves to feed a sheet from said pair of reverse-discharge rotating members to said conveyor;
• and
• wherein said electricity removal unit is arranged disposed at a downstream side in a sheet discharging direction from a cross over position for a front edge of the sheet and a rear edge of the sheet in a case of conveying the sheet having maximum conveyable length by switchback, and at a downstream side in the sheet discharging direction of said pair of reverse-discharge rotating members.

An original document processing apparatus comprising:

• a conveyor for conveying an original document to an original document reading position;
• a pair of reverse-discharge rotating members capable of rotating forward and reverse for feeding the original document to said conveyor by switchback, and discharging the original document conveyed from said conveyor;
• and
• electricity removal unit for removing electricity from the conveyed sheet;
• wherein the switchback serves to feed on original document from said pair of reverse-discharge rotating members to said conveyor;
• and
• wherein said electricity removal unit is disposed at a downstream side in an original document discharging direction from a cross over position for a front edge of the original document and a rear edge of the original document in a case of conveying the original document having a maximum conveyable length by switchback, and at a downstream side in the original document discharging direction of said pair of reverse-discharge rotating members.
