Abstract

Abstract Sheet printing and collating apparatus includes a sheet sorter which has a stapler for stapling sets of sheets in the sorter bins. The stapler is actuated by an electric motor to which the applied power is varied depending upon the number of sheets of paper in the sets and therefore, the thickness of the sets to be stapled. Sheets entering the sorter trays are counted and information as to the number of sheets per set is supplied to the microprocessor unit which controls the stapler to supply control signals to a variable power supply to the stapler motor so that the motor power applied to the stapler increases as the number of sheets per set increases.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 121 words
In an in-bin stapling sorter comprising a plurality of trays for receiving sets of sheets, a stapler, means for relatively moving the stapler and the sets of sheets between a non-stapling and a stapling position, and drive means for said stapler to insert a staple in a set of sheets in said stapling position, the improvement wherein said drive means for said stapler includes an electric motor and control means for said motor for selectively energizing said motor to operate said stapler at higher or lower power depending upon the thickness of sets of sheets, said control means including means for counting the sheets in said sets to selectively energize said motor depending upon the number of sheets constituting a set.
Claim 2
Dependent Claim 121 words
In an in-bin stapling sorter comprising a plurality of trays for receiving sets of sheets, a stapler, means for relatively moving the stapler and the sets of sheets between a non-stapling and a stapling position, and drive means for said stapler to insert a staple in a set of sheets in said stapling position, the improvement wherein said drive means for said stapler includes an electric motor and control means for said motor for selectively energizing said motor to operate said stapler at higher or lower power depending upon the thickness of sets of sheets, said control means including means for counting the sheets in said sets to selectively energize said motor depending upon the number of sheets constituting a set.
Claim 3
Dependent Claim 38 words
In a sorter as defined in claim 1, said motor being a DC motor and said control means includes a motor controller responsive to the thickness of sets of sheets to adjust the power supplied to said motor.
Claim 4
Dependent Claim 53 words
In a sorter as defined in claim 1, said control means including means for counting the sheets in said sets in a plurality of stages of a predetermined range of numbers of sheets to selectively energize said motor with power in stages depending upon the range of numbers of sheets in said sets.
