Abstract

By pivotally mounting the document sheet drive rollers 1, 2 about a common pivot point 3 within the copier the same rollers 1, 2 may be utilized in one copying mode for document ejection after copying from a moving or semi-moving platen, and then pivoted into a different position for another copying mode in which the same rollers 1, 2 are used for a constant velocity document transport for document copying movement over a stationary platen. In the latter CVT mode, the rolls are held stationary over the platen in the illustrated solid line position overlying the optics path 4. In the former moving platen mode the rolls travel with the platen away from the optics area 4 out to the platen's maximum scan position (the illustrated dashed line position) where they capture the document at the end of scan and eject the document from the platen as the platen returns to its home position.

By pivotally mounting the document sheet drive rollers 1, 2 about a common pivot point 3 within the copier the same rollers 1, 2 may be utilized in one copying mode for document ejection after copying from a moving or semi-moving platen, and then pivoted into a different position for another copying mode in which the same rollers 1, 2 are used for a constant velocity document transport for document copying movement over a stationary platen. In the latter CVT mode, the rolls are held stationary over the platen in the illustrated solid line position overlying the optics path 4. In the former moving platen mode the rolls travel with the platen away from the optics area 4 out to the platen's maximum scan position (the illustrated dashed line position) where they capture the document at the end of scan and eject the document from the platen as the platen returns to its home position.

Driving of these rolls 1, 2 in both positions can be accomplished without a drive system disconnect by retaining the drive belts 5 in the pulley grooves with retainers. This allows both legs of the belt 5 to relax and flex as the pulleys 2 move from one position to the other position and back.
