  • At least one drive roller associated with the original document transport system for transporting the original document toward the scanning window when the movable section is in either said sheet copier or book copier position;
  • a document clutch means associated with said drive roller and said chain, said document clutch means having a first position when the drive roller is coupled to the main chain and a second position when the drive roller is decoupled from the main chain, said document clutch means being switched from the first position to the second position when the original document reaches the output end.
  • a reproduction apparatus including a frame having at least one sidewall, an original document transport means for moving an original document through a pathway from an input end to an output end, a scanning window disposed in the pathway, a copy paper transport means for transporting copy paper through a copy paper pathway, power means for driving said transport means, camera means for reproducing the document onto the copy paper as the document moves past the scanning window, said original document transport means comprising:
  • a movable section having at least one idler roller
  • a stationary section having at least one drive roller associated with said power means, said movable section having a sheet copier position when said idler roller is in juxtaposition with the drive roller and a book copier position when said idler roller is disassociated from said drive roller, said idler roller cooperating with the drive roller for conveying the original document when the movable section is in said sheet copier position;
  • the reproduction apparatus of claim 19 includes:
  • a removable carrier for use when the apparatus is used as a book copier, said carrier including an actuator means for association with said track means, said actuator means cooperating with the control means to cause said sweep movement.
  • the reproduction apparatus of claim 9, includes:
  • a holder means for holding said document, said holder means being insertable between the drive roller and the idler roller when the apparatus is used as a sheet copier, said holder means including actuator means for association with said track means, said actuator means cooperating with the control means to cause said sweep movement.
  • a reproduction apparatus including a frame having at least one sidewall, an original document transport means for moving an original document through a pathway from an input end to an output end, a scanning window disposed in the pathway, a copy paper transport means for transporting copy paper through a copy paper pathway, power means for driving said transport means, camera means for reproducing the document onto the copy paper as the document moves past the scanning window, said original document transport means comprising:
  • a movable section having a sheet copier position and a book copier position:
  • a stationary section associated with said power means, said movable section being in juxtaposition with the stationary section when in said sheet copier position whereby the movable and stationary sections cooperate and transport a sheet document across the scanning window, said movable section being positioned outward from the stationary section when in said book copier position;
  • pivot means enabling the movable section to be rotated from the sheet copier position to the book copier position and from the book copier position to the sheet copier position, one of said pivot means enabling the movable section to be rotated from one of said positions to an intermediate point between said positions, the other pivot means enabling the movable section to be rotated from the intermediate point to the other of said positions.
