Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
135 words
A copying device comprising: a first scanning means for exposing an original while it is being fed; a second scanning means comprising a reciprocally moving member for exposing the original; process means for performing a copying operation based on the exposed original image; a guide member for being set to feed the original so that a copying operation by said first scanning means is performed; and control means responsive to said setting of said guide member, during a copying operation by said second scanning means, for suspending the copying operation being carried out so as to enable the copying operation by said first scanning means to be carried out, and to enable the copying operation by said second scanning means to be resumed after the completion of the copying operation by said first scanning means.
Claim 2
Dependent Claim
135 words
A copying device comprising: a first scanning means for exposing an original while it is being fed; a second scanning means comprising a reciprocally moving member for exposing the original; process means for performing a copying operation based on the exposed original image; a guide member for being set to feed the original so that a copying operation by said first scanning means is performed; and control means responsive to said setting of said guide member, during a copying operation by said second scanning means, for suspending the copying operation being carried out so as to enable the copying operation by said first scanning means to be carried out, and to enable the copying operation by said second scanning means to be resumed after the completion of the copying operation by said first scanning means.
Claim 3
Dependent Claim
28 words
A copying device as set forth in claim 1 wherein said control means inhibits the copying operation by said second scanning means while said guide member is set.
Claim 4
Dependent Claim
34 words
A copying device as set forth in claim 1 wherein said guide member receives a plurality of sheet originals thereon, and said first scanning means continuously feeds the originals received on said guide member.
Claim 5
Dependent Claim
56 words
A copying device as set forth in claim 1 further comprising storage means for storing information regarding the copy operation being carried out at the time when said guide member is set, wherein said control means recalls the information stored in said storage means after the completion of the copying operation by said first scanning means.
Claim 6
Dependent Claim
27 words
A copying device as set forth in claim 4 wherein said storage means stores a desired number of copies, the number of copied sheets, and copy size.
Claim 7
Dependent Claim
29 words
A copying device as set forth in claim 4 wherein said control means recalls the information from said storage means in response to the resetting of said guide member.
Claim 8
Dependent Claim
123 words
A copying device having a plural number of copy modes comprising: means for selecting one of said copy modes; first control means responsive to the operation of said selecting means during a copying operation for causing the copying operation being executed to be suspended to permit a copying operation associated with the newly selected copy mode, and for causing the suspended copying operation to be resumed after completion of the copying operation associated with the selected copy mode; and second control means for permitting the control operation of said first control means during a copying operation associated with a first copy mode, and for inhibiting the control operation of said first control means during a copying operation associated with a second copy mode.
Claim 9
Dependent Claim
123 words
A copying device having a plural number of copy modes comprising: means for selecting one of said copy modes; first control means responsive to the operation of said selecting means during a copying operation for causing the copying operation being executed to be suspended to permit a copying operation associated with the newly selected copy mode, and for causing the suspended copying operation to be resumed after completion of the copying operation associated with the selected copy mode; and second control means for permitting the control operation of said first control means during a copying operation associated with a first copy mode, and for inhibiting the control operation of said first control means during a copying operation associated with a second copy mode.
Claim 10
Dependent Claim
41 words
A copying device according to claim 7 further comprising means for storing information concerning the interrupted copying operation, wherein when the interrupted copying operation is resumed, the copying operation is carried out based on the information stored in said storage means.
Claim 11
Dependent Claim
68 words
A copying device having a plural number of copy modes comprising: means for selecting one of said copy modes; means for displaying information concerning a copying operation; and switching means responsive to the mode selection of said selecting means for switching the display content of said display means such that in a first mode a numeral is displayed, and in a second mode a mode-related signal is displayed.
Claim 12
Dependent Claim
68 words
A copying device having a plural number of copy modes comprising: means for selecting one of said copy modes; means for displaying information concerning a copying operation; and switching means responsive to the mode selection of said selecting means for switching the display content of said display means such that in a first mode a numeral is displayed, and in a second mode a mode-related signal is displayed.
Claim 13
Dependent Claim
18 words
A copying device according to claim 9 wherein said display means includes a display element having seven segments.
Claim 14
Dependent Claim
28 words
A copying device according to claim 9 further comprising means responsive to the mode selection of said selecting means for storing the information displayed on said display means.
Claim 15
Dependent Claim
79 words
A copying device comprising: a first interrupting means for interrupting a copying operation being executed to permit a new copying operation according to a first mode; a second interrupting means for interrupting a copying operation being executed to permit a new copying operation according to a second mode different from said first mode; and control means for inhibiting the copying operation according to said second interrupting means, while the copying operation according to said first interrupting means is performed.
Claim 16
Dependent Claim
79 words
A copying device comprising: a first interrupting means for interrupting a copying operation being executed to permit a new copying operation according to a first mode; a second interrupting means for interrupting a copying operation being executed to permit a new copying operation according to a second mode different from said first mode; and control means for inhibiting the copying operation according to said second interrupting means, while the copying operation according to said first interrupting means is performed.
Claim 17
Dependent Claim
36 words
A copying device according to claim 12 wherein after the completion of the copying operation according to said first and second interrupting means, the copying operation according to the copy mode before the interruption is resumed.
