Image forming device with a printer unit and a copying unit

An image forming device having a first image forming unit which prints documents while transporting said documents in a first direction, and a second image forming unit which copies images printed on said documents while transporting said documents in a second direction different from said first direction, said image forming device comprising:

• a document stacking unit for sequentially stacking documents discharged from said first image forming unit;
• a fixed position defining member disposed on said document stacking unit for positionally defining a trailing edge of said documents in said first direction;
• a discharge member disposed a predetermined distance from said fixed position defining member in a first discharge direction, for discharging said documents to said document stacking unit;
• a movable position defining member disposed downstream from said document stacking unit in said first direction, for positionally defining a leading edge of said documents;
• a defining member driving means for moving said movable position defining member when said documents are discharged by said discharge member;
• and
• a discharge mechanism for transporting said documents stacked on said document stacking unit in said second direction to said second image forming unit.

An image forming device having a first image forming unit for forming images on documents, and a second image forming unit for forming images in accordance with images formed on documents in said first image forming unit, said image forming device comprising:

• a first transport means for transporting paper to said first image forming unit in a first direction, and for discharging documents formed in said first image forming unit in said first direction;
• a document stacking unit for sequentially stacking documents discharged from said first transport means;
• a second transport means for transporting documents from said document stacking unit to said second image forming unit in a second direction different from said first direction;
• drive means for driving said first transport means and said second transport means;
• and
