Abstract
An apparatus which delivers to an operator offset batches of sheets reproduced from at least one set of documents. The operator selects the number of sheets or sets of sheets successive batches to be offset from one another. In this way, the number of copy sheets in the batch may range from a partial set of copy sheets to multiple sets of copy sheet. Also, the operator may select no offset within a job providing a straight stack with no distinction between batches or sets.
Claims20
An apparatus for delivering to an operator offset batches of sheets reproduced from at least one set of documents, including:
- means for selecting the number of sheets of each batch to be offset from one another;
- means for receiving and supporting the sheets;
- and
- means, responsive to said selecting means, for moving said receiving and supporting means at selected intervals to offset from one another a selected number of sheets corresponding to a batch of sheets with the selected number of sheets in the batch ranging from a number of sheets less than a complete set to a number of sheets greater than a complete set.
An apparatus for delivering to an operator offset batches of sheets reproduced from at least one set of documents, including:
- means for selecting the number of sheets of each batch to be offset from one another comprises means for controlling said moving means, and a display having a plurality of operator actuatable regions thereon with each region defining the number of sheets of each batch offset from one another;
- means for receiving and supporting the sheets;
- and
- means, responsive to said selecting means, for moving said receiving and supporting means at selected intervals to offset from one another a selected number of sheets corresponding to a batch of sheets with the selected number of sheets in the batch ranging from a number of sheets less than a complete set to a number of sheets greater than a complete set.
An apparatus for delivering to an operator offset batches of sheets reproduced from at least one set of documents, including:
- means for selecting the number of sheets of each batch to be offset from one another said selecting means comprises means for controlling said moving means, and a display having a plurality of operator actuatable regions thereon with each region defining the number of sheets of each batch offset from one another;
- means for receiving and supporting the sheets, said receiving and supporting means comprises a tray;
- and
- means, responsive to said selecting means, for moving said receiving and supporting means at selected intervals to offset from one another a selected number of sheets corresponding to a batch of sheets with the selected number of sheets in the batch ranging from a number of sheets less than a complete set to a number of sheets greater than a complete set, said moving means comprises a motor coupled to said tray and regulated by said controller to move at an interval corresponding to the selected number of sheets so as to offset successive batches of sheets from one another, said moving means includes means for detecting that said tray is in an offset position and in a non-offset position, said detecting means being connected to said controller which regulates said motor in response thereto.
An electrophotographic printing machine of the type in which copy sheets reproduced from at least one set of original documents are advanced to a finishing station for finishing and delivery of offset batches of copy sheets to the printing machine operator, wherein the improvement includes:
- means for selecting the number of copy sheets of each batch to be offset from one another;
- means for receiving and supporting the copy sheets;
- and
- means, responsive to said selecting means, for moving said receiving an supporting means at selected intervals to offset from one another a selector number of copy sheets corresponding to a batch of copy sheets with the selected number of copy sheets in the batch ranging from a number of copy sheets less than a complete set to a number of copy sheets greater than a complete set.
An electrophotographic printing machine of the type in which copy sheets reproduced from at least one set of original documents are advanced to a finished station for finishing and delivery of offset batches of copy sheets to the printing machine operator, wherein the improvement includes:
- means for selecting the number of copy sheets of each batch to be offset from one another said selecting means comprises means for controlling said moving mean' and a display having a plurality of operator actuatable regions thereon with each region defining the number of copy sheets of each batch offset from one another;
- means for receiving and supporting the copy sheets;
- and
- means, responsive to said selecting means, for moving said receiving an supporting means at selected intervals to offset from one another a selected number of copy sheets corresponding to a batch of copy sheets with the selected number of copy sheets in the batch ranging from a number of copy sheets less than a complete set to a number of copy sheets greater than a complete set.
An electrophotographic printing machine of the type in which copy sheets reproduced from at least one set of original documents are advanced to a finishing station for finishing and delivery of offset batches of copy sheets to the printing machine operator, wherein the improvement includes:
- means for selecting the number of copy sheets of each batch to be offset from one another said selecting means comprises means for controlling said moving means, and a display having a plurality of operator actuatable regions thereon with each region defining the number of copy sheets of each batch offset from one another;
- means for receiving and supporting the copy sheets, said receiving and supporting means comprises a tray;
- and
- means, responsive to said selecting means, for moving said receiving and supporting means at selected intervals to offset from one another a selected number of copy sheets corresponding to a batch of copy sheets with the selected number of copy sheets in the batch ranging from a number of copy sheets less than a complete set to a number of copy sheets greater than a complete set, said moving means comprises a motor coupled to said tray and regulated by said controller to move at an interval corresponding to the selected number of copy sheets so as to offset successive batches of copy sheets from one another, said moving means includes means for detecting that said tray is in an offset position and in a non-offset position, said detecting means being connected to said controller which regulates said motor in response thereto.
