Abstract
Abstract A copying paper processing apparatus comprises a sorter, a stapling device for stapling sheets of copying paper sorted by the sorter, and a device for automatically selecting and setting a sort mode when a staple mode is selected and set. The processing apparatus may comprise a switch for selecting the stapling operation, and a device for automatically selecting and setting a staple mode when the staple selecting switch is turned on and a sort mode is selectively set. The processing apparatus may comprise a device for transmitting a signal indicating that there is no staple needle when the number of staple needles left in the stapling device is a predetermined number greater than the total number of bins of the sorter. The processing apparatus may comprise a device for inhibiting the operation of the stapling device when one of sensors respectively disposed in a paper-receiving base of the stapling device and a sorter bin of the sorter detects that there is no paper.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
39 words
A copying paper processing apparatus comprising: a sorter; a stapling device for stapling sheets of copying paper sorted by the sorter; and means for automatically selecting and setting a sort mode when a staple mode is selected and set.
Claim 2
Dependent Claim
39 words
A copying paper processing apparatus comprising: a sorter; a stapling device for stapling sheets of copying paper sorted by the sorter; and means for automatically selecting and setting a sort mode when a staple mode is selected and set.
Claim 3
Dependent Claim
36 words
A copying paper processing apparatus as claimed in claim 1, wherein the stapling device is operated in the staple mode and is not operated in a state in which the sorting operation is not correctly performed.
Claim 4
Dependent Claim
32 words
A copying paper processing apparatus as claimed in claim 1, wherein said stapling device includes arranging means for arranging the sheets of the copying paper sorted by the sorter prior to stapling.
Claim 5
Dependent Claim
55 words
A copying paper processing apparatus as claimed in claim 3, wherein the arranging means comprises a pressure plate for pressing one side of the sheets of the copying paper along the copying paper so as to arrange the sheets of the copying paper by a predetermined movement according to the size of the copying paper.
Claim 6
Dependent Claim
52 words
A copying paper processing apparatus as claimed in claim 4, wherein the arranging means further comprises a stopper for stopping the sheets of the copying paper pressed by the pressure plate at the other side of the sheets of the copying paper so as to arrange the sheets of the copying paper.
Claim 7
Dependent Claim
43 words
A copying paper processing apparatus as claimed in claim 1, wherein, even if the staple mode is selected, the setting of the staple mode is inhibited while it is detected that there is already a sheet of paper in bins of the sorter.
Claim 8
Dependent Claim
109 words
A copying paper processing apparatus comprising: a sorter; a stapling device for stapling sheets of copying paper sorted by the sorter; and means for transmitting a signal indicating that there is no staple needle when the number of staple needles left in the stapling device is a predetermined number greater than the total number of bins of the sorter; wherein the signal indicating that there is no staple needle is not transmitted even when the number of staple needles left in the stapling device is less than said predetermined number during the operation of the stapling device with respect to the sheets of copying paper sorted by the sorter.
Claim 9
Dependent Claim
109 words
A copying paper processing apparatus comprising: a sorter; a stapling device for stapling sheets of copying paper sorted by the sorter; and means for transmitting a signal indicating that there is no staple needle when the number of staple needles left in the stapling device is a predetermined number greater than the total number of bins of the sorter; wherein the signal indicating that there is no staple needle is not transmitted even when the number of staple needles left in the stapling device is less than said predetermined number during the operation of the stapling device with respect to the sheets of copying paper sorted by the sorter.
Claim 10
Dependent Claim
35 words
A copying paper processing apparatus as claimed in claim 7, wherein all the sheets of copying paper are stapled by the stapling device until the signal indicating that there is no staple needle is transmitted.
Claim 11
Dependent Claim
38 words
A copying paper processing apparatus as claimed in claim 7, wherein all the sheets of copying paper in the sorter bins are stapled at least once after the signal indicating that there is no staple needle is transmitted.
