Claims
- 1. A sheet aligning arrangement which is arranged to accommodate a plurality of sheets fed thereinto for alignment, and to feed out the aligned sheets therefrom one sheet by one sheet, said sheet aligning apparatus comprising:
- feed roller means for feeding the sheets;
- a slidable alignment member slidable between a first position which defines a first sheet aligning reference position and a second position parallel to said first position and defining a first sheet transport reference position;
- a pivotable alignment member located in a position confronting said slidable alignment member, and being pivotable about a fixed axis extending in a direction parallel to a sheet transport direction; and
- slidable alignment member displacing means for positioning the slidable alignment member in the first position during a preliminary alignment of the sheets carried out by the pivotable alignment member and for sliding the slidable alignment member to the second position and maintaining the slidable alignment member at the second position during a final alignment of the sheets carried out by the pivotable alignment member at the time of feeding of the sheets by the feed roller means.
- 2. A sheet aligning arrangement as claimed in claim 1, further comprising a pivotable alignment member displacing means for pivoting said pivotable alignment member about the fixed axis to place the sheets fed into the arrangement in contact with the slidable alignment member located at the first position during the preliminary alignment of the sheets, and for pivoting said pivotable alignment member about the fixed axis toward a fixed position parallel to said second position of the slidable alignment member and defining a second sheet transport reference position during the feeding of the sheets by said feed roller means.
- 3. A sheet aligning arrangement which is arranged to accommodate a plurality of sheets fed thereinto for alignment, and to feed out the aligned sheets therefrom through a sheet feeding passage one sheet by one sheet, said sheet aligning apparatus comprising:
- a feed roller for feeding the sheets;
- a slidable alignment member slidable between a first position which defines a first sheet aligning reference position and a second position parallel to said first position and defining a first sheet transport reference position;
- a pivotable alignment member located in a position confronting said slidable alignment member and parallel to said second position of the slidable alignment member, the pivotable alignment member being pivotable about a fixed axis to a fixed position defining a second sheet transport reference position;
- slidable alignment member displacing means for sliding said slidable alignment member to the first position during a preliminary alignment of the sheets, and for sliding said slidable alignment member to the second position during a final alignment and feeding of the sheets; and
- a pivotable alignment member pivoting means for pivoting said pivotable alignment member about said fixed axis to place the sheets fed into the arrangement in contact with the slidable alignment member located at the first position during the preliminary alignment of the sheets, and for pivoting said pivotable alignment member about said fixed axis toward said fixed position to place the sheets fed into the arrangement in contact with said slidable alignment member located at said second position for final alignment of the sheets during the feeding of the sheets by said feed roller.
- 4. A sheet aligning arrangement as claimed in claim 3, further comprising a leading edge aligning member located between said slidable and pivotable alignment members for positioning a sheet feeding direction leading edge of the sheets, said leading edge aligning member being adapted to retreat from the sheet feeding passage during feeding of the sheets.
- 5. A sheet aligning arrangement for use in a copying apparatus, arranged to receive a plurality of paper sheets each copied at one side thereof for alignment, and to feed the aligned paper sheets through a sheet feeding passage one sheet by one sheet, said sheet aligning arrangement comprising:
- a feed roller for feeding the stacked paper sheets one sheet by one sheet,
- first and second aligning members of plate-like configuration provided in parallel relation to each other so as to accommodate the paper sheets therebetween,
- said first aligning member being slidable between a first position defining a first sheet aligning reference position and a second position defining a first sheet transport reference position parallel to said first position, and said second aligning member being parallel to said second position and pivotable about a fixed axis and positionable in a fixed position defining a second sheet transport reference position, the sheets fed into the arrangement being placed in contact with said first aligning member by repeated pivoting of said second aligning member about said fixed axis and through tapping one side edge of the sheets, and
- aligning member displacing means for sliding said first aligning member to said first position during a preliminary aligning of the sheets carried out by pivoting of said second aligning member to place the paper sheets fed into the arrangement in contact with said first aligning member located at said first position, and, during feeding of the paper sheets one sheet by one sheet by said feed roller, for sliding said first aligning member to said second position during a final aligning of the sheets carried out by pivoting of said second aligning member to said fixed position so as to place the paper sheets fed into the arrangement in contact with said first aligning member located at said second position.
- 6. A sheet aligning arrangement as claimed in claim 5, further comprising a leading edge aligning member of a plate-like configuration located between said first and second aligning members for positioning a sheet feeding direction leading edge of each of the sheets, said leading edge aligning member being adapted to retreat from the sheet feeding passage during feeding of the paper sheets one sheet by one sheet by the feed roller.
- 7. A sheet aligning arrangement as claimed in claim 5, wherein said sheet aligning arrangement is detachably mounted on a main body of the copying apparatus.
- 8. A sheet aligning arrangement which is arranged to accommodate a plurality of sheets fed thereinto for alignment, and to feed out the aligned sheets therefrom one sheet by one sheet, said sheet aligning apparatus comprising:
- a feed roller means for feeding the sheets;
- a first aligning member slidable between a first position which defines a first sheet aligning reference position and a second position defining a first sheet transport reference position located at a position different from said first position;
- a second aligning member located in a position confronting said first aligning member, and being pivotable about a fixed axis extending in a direction parallel to a sheet transport direction; and
- first aligning member displacing means for sliding said first aligning member to said first position during a preliminary alignment carried out by the second aligning member, and for sliding said first aligning member to said second position during a final alignment of the sheets carried out by the second aligning member.
- 9. A sheet aligning arrangement as claimed in claim 1, wherein the width between the first position and the fixed position is larger than the width of sheets to be accommodated in the direction perpendicular to the direction of transport of the sheets with the fixed position taken as a reference edge.
- 10. A sheet aligning arrangement as claimed in claim 3, wherein the width between the first position and the fixed position is larger than the width of sheets to be accommodated in the direction perpendicular to the direction of transport of the sheets with the fixed position taken as a reference edge.
- 11. A sheet aligning arrangement as claimed in claim 5, wherein the width between the first position and the fixed position is larger than the width of sheets to be accommodated in the direction perpendicular to the direction of transport of the sheets with the fixed position taken as a reference edge.
