Collating apparatus for copying machine

Claim 2

A collating apparatus including a plurality of bins, deflector means for deflecting sheets into selected bins, feed means for feeding the sheets to the deflector means and discharge sensor means for sensing discharge of sheets from the deflector means into the bins, characterized by comprising: sheet number storage means for storing a number representing the quantity of sheets to be collated; discharge counter means for counting a number of sheets discharged into the bins; comparator means for comparing the number of sheets discharged into the bins with the number of sheets to be collated and producing a next collating operation enable signal when said numbers are equal; inlet sensor means for sensing entry of sheets into the feed means, inlet counter means for counting a number of sheets which entered the feed means, jam sensor means for sensing a sheet jam and producing a jam signal in response thereto; and a copying machine for copying a document and feeding the sheets in the form of copies of the document to the feed means, the copying machine comprising copy counter means for counting a number of copies produced, the apparatus further comprising means for directly transferring a count in the discharge counter means which represents the number of sheets discharged into the bins into the copy counter means to constitute a new count in the copy counter means in response to the jam signal.

Claim 3

An apparatus as in claim 1, in which the copying machine, in response to the enable signal, is enabled to copy a next document and feed copies thereof to the feed means for collation.

Claim 4

An apparatus as in claim 2, in which the copying machine comprises an automatic document handler for feeding the next document to a copying position in the copying machine in response to the enable signal.

Claim 5

An apparatus as in claim 1, further comprising a discharge tray and means for controlling the feed means to feed sheets into the discharge tray rather than to the deflector means in response to the jam signal.

Claim 6

An apparatus as in claim 1, in which the jam sensor means is constructed to produce the jam signal when the discharge sensor means does not sense a sheet within a predetermined length of time after the sheet is sensed by the inlet sensor means.

Claim 7

An apparatus as in claim 1, in which the jam sensor means is constructed to produce the jam signal when the discharge sensor means does not sense a trailing edge of a sheet within a predetermined length of time after sensing a leading edge of the sheet.

Claim 8

A collating apparatus including a plurality of bins, deflector means for deflecting sheets into selected bins, feed means for feeding the sheets to the deflector means and discharge sensor means for sensing discharge of sheets from the deflector means into the bins, characterized by comprising: sheet number storage means for storing a number representing the quantity of sheets to be collated; discharge counter means for counting a number of sheets discharged into the bins; comparator means for comparing the number of sheets discharged into the bins with the number of sheets to be collated and producing a next collating operation enable signal when said numbers are equal; inlet sensor means for sensing entry of sheets into the feed means, inlet counter means for counting a number of sheets which entered the feed means, jam sensor means for sensing a sheet jam and producing a jam signal in response thereto; a copying machine for copying a document and feeding the sheets in the form of copies of the document to the feed means, the copying machine comprising copy counter means for counting a number of copies produced, the apparatus further comprising means for directly transferring a count in the discharge counter means which represents the number of sheets discharged into the bins into the copy counter means to constitute a new count in the copy counter means in response to the jam signal; and manual insertion means for allowing manual insertion of sheets into the feed means for collation.

Claim 9

A collating apparatus including a plurality of bins, deflector means for deflecting sheets into selected bins, feed means for feeding the sheets to the deflector means and discharge sensor means for sensing discharge of sheets from the deflector means into the bins, characterized by comprising: sheet number storage means for storing a number representing the quantity of sheets to be collated; discharge counter means for counting a number of sheets discharged into the bins; comparator means for comparing the number of sheets discharged into the bins with the number of sheets to be collated and producing a next collating operation enable signal when said numbers are equal; inlet sensor means for sensing entry of sheets into the feed means, inlet counter means for counting a number of sheets which entered the feed means, jam sensor means for sensing a sheet jam and producing a jam signal in response thereto; a copying machine for copying a document and feeding the sheets in the form of copies of the document to the feed means, the copying machine comprising copy counter means for counting a number of copies produced, the apparatus further comprising means for directly transferring a count in the discharge counter means which represents the number of sheets discharged into the bins into the copy counter means to constitute a new count in the copy counter means in response to the jam signal; and manual insertion means for allowing manual insertion of sheets into the feed means for collation.
