Abstract
Abstract A copying machine is provided with a sheet stapling device for both automatically fastening together in a corner area a bundle of sheets successively printed in the copying machine and fastening together a bundle of sheets manually inserted in an externally accessible opening formed in the side of the stapling device. Preferably, the opening is formed by an elongated slot which extends to the operating side of the copying machine and which coincides with the opening through which sheets printed in the copying machine are discharged from the stapling device. A bundle of sheets can be inserted in the opening so that any edge part is under the stapling means. Thus, the inserted bundle can be stapled at different places along any edge. The opening is provided with two detectors to determine when a bundle of sheets inserted manually is correctly positioned under the stapling device and to initiate the stapling action.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
125 words
A copying machine having a sheet stapling device comprising a support for collecting sheets printed in the copying machine into a bundle; a stapling means for fastening together a bundle of collected sheets at an edge; a means for discharging the bundle of collected sheets from the support through an elongated opening; and an externally accessible opening in the sheet stapling device through which a bundle of sheets can be manually inserted such that only a small portion of the bundle needs to be inserted before it is aligned with the stapling means and wherein both the stapling means and the opening have been provided at the same part of the support on which a corner area of the bundle of collected sheets is situated.
Claim 2
Dependent Claim
125 words
A copying machine having a sheet stapling device comprising a support for collecting sheets printed in the copying machine into a bundle; a stapling means for fastening together a bundle of collected sheets at an edge; a means for discharging the bundle of collected sheets from the support through an elongated opening; and an externally accessible opening in the sheet stapling device through which a bundle of sheets can be manually inserted such that only a small portion of the bundle needs to be inserted before it is aligned with the stapling means and wherein both the stapling means and the opening have been provided at the same part of the support on which a corner area of the bundle of collected sheets is situated.
Claim 3
Dependent Claim
49 words
A copying machine as described in claim 1 wherein a control means is provided to activate the stapling means, the control means comprising at least one detector which reacts to a bundle of sheets manually inserted into the externally accessible opening to cause the stapling means to be activated.
Claim 4
Dependent Claim
48 words
A copying machine as described in claim 2 wherein the control means comprises two detectors, one situated before and to one side of a stapling location and the other situated behind and to the other side of the stapling location when viewed lengthwise of the externally accessible opening.
Claim 5
Dependent Claim
25 words
A copying machine as described in claim 1 wherein the stapling means is provided in the forepart of the copying machine near the operating side.
Claim 6
Dependent Claim
73 words
A copying machine as described in claim 4 wherein: the externally accessible opening is the same as the elongated opening through which the bundle of collected sheets is discharged from the support; the elongated opening can be closed by a first stop for retaining sheets fed onto the support; and the stapling means is arranged so that it can staple a bundle of sheets along an edge extending lengthwise of the elongated opening.
Claim 7
Dependent Claim
49 words
A copying machine as described in claim 5 wherein a control means is provided to activate the stapling means, the control means comprising at least one detector which reacts to a bundle of sheets manually inserted into the externally accessible opening to cause the stapling means to be activated.
Claim 8
Dependent Claim
48 words
A copying machine as described in claim 6 wherein the control means comprises two detectors, one situated before and to one side of a stapling location and the other situated behind and to the other side of the stapling location when viewed lengthwise of the externally accessible opening.
Claim 9
Dependent Claim
87 words
A copying machine as described in claim 7 wherein a second stop which extends in a direction parallel to the first stop is provided in the externally accessible opening beside the path of movement of sheets collected on the support, against which a bundle of sheets manually inserted into the externally accessible opening can be moved, and wherein one of the detectors is located before the second stop at a distance being considerably smaller than the distance between that detector and the edge of the second stop.
Claim 10
Dependent Claim
30 words
A copying machine as described in claim 5 wherein a first control means is provided which deactivates the first stop when no sheets are being processed in the copying machine.
Claim 11
Dependent Claim
49 words
A copying machine as described in claim 9 wherein a control means is provided to activate the stapling means, the control means comprising at least one detector which reacts to a bundle of sheets manually inserted into the externally accessible opening to cause the stapling means to be activated.
Claim 12
Dependent Claim
48 words
A copying machine as described in claim 10 wherein the control means comprises two detectors, one situated before and to one side of a stapling location and the other situated behind and to the other side of the stapling location when viewed lengthwise of the externally accessible opening.
Claim 13
Dependent Claim
87 words
A copying machine as described in claim 11 wherein a second stop which extends in a direction parallel to the first stop is provided in the externally accessible opening beside the path of movement of sheets collected on the support, against which a bundle of sheets manually inserted into the externally accessible opening can be moved, and wherein one of the detectors is located before the second stop at a distance being considerably smaller than the distance between that detector and the edge of the second stop.
Claim 14
Dependent Claim
49 words
A copying machine as described in claim 4 wherein a control means is provided to activate the stapling means, the control means comprising at least one detector which reacts to a bundle of sheets manually inserted into the externally accessible opening to cause the stapling means to be activated.
Claim 15
Dependent Claim
48 words
A copying machine as described in claim 13 wherein the control means comprises two detectors, one situated before and to one side of a stapling location and the other situated behind and to the other side of the stapling location when viewed lengthwise of the externally accessible opening.
