Abstract
Abstract The present invention is directed towards an improvement in a copying apparatus capable of executing a plurality of copy modes including an ordinary copy mode and one or more special purpose copy modes. A mode key switch is provided for setting the copy mode to the ordinary copy mode or to the special purpose copy mode. The mode key switch is biased to normally select the ordinary copy mode. Input keys are provided for inputting values for the special purpose copy mode, and a visual display may be provided for displaying the values set with the input keys. The values of the special purpose copy mode may be changed by operating the input keys while continually depressing the mode key switch. The photocopier is inhibited from making any changes in copying mode while the operator is setting the desired values.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
In an apparatus which is capable of executing a specific operation mode and a normal operation mode, said apparatus comprising: switch means capable of being in a depressed condition and in a released condition, said switch means normally in the released condition and in the depressed condition while said switch means held depressed; first means for changing the operation mode from the normal operation mode to the specific operation mode in response to the change from the released condition to the depressed condition of said switch means; second means for changing the operation mode from the specific operation mode to the normal operation mode in response to the change from the depressed condition to the released condition of said switch means; means for supplying a numerical data in response to the selection of specific operation mode; means, which is operable when said switch means is in the depressed condition, for varying the numerical data; and means for inhibiting the operation of said second means immediately after the numerical data is varied.
Claim 2
Dependent Claim
171 words
In an apparatus which is capable of executing a specific operation mode and a normal operation mode, said apparatus comprising: switch means capable of being in a depressed condition and in a released condition, said switch means normally in the released condition and in the depressed condition while said switch means held depressed; first means for changing the operation mode from the normal operation mode to the specific operation mode in response to the change from the released condition to the depressed condition of said switch means; second means for changing the operation mode from the specific operation mode to the normal operation mode in response to the change from the depressed condition to the released condition of said switch means; means for supplying a numerical data in response to the selection of specific operation mode; means, which is operable when said switch means is in the depressed condition, for varying the numerical data; and means for inhibiting the operation of said second means immediately after the numerical data is varied.
Claim 3
Dependent Claim
51 words
A copying apparatus as claimed in claim 1 wherein said specific operation mode is a binding margin forming mode for forming a blank margin on one side of a copy to be formed and said supplying means supplies the numerical value equivalent to a length of the margin to be formed.
Claim 4
Dependent Claim
44 words
A copying apparatus as claimed in claim 1 wherein said specific operation mode is an anamorphic copy mode for forming a copy with an image enlarged or contracted in one direction and said supplying means supplies the numerical value corresponding to a magnification ratio.
Claim 5
Dependent Claim
169 words
In a copying apparatus which is capable of executing a plurality of copy modes inclusive of a first copy mode and one or more second copy modes, said apparatus comprising: switch means capable of being in a first condition and in a second condition by actuation thereof, said switch means being biased to be in the first condition; means for changing the copy mode in response to the actuation of said switch means, the change to the second copy mode from the first copy mode is effected by the change to the second condition from the first condition of said switch means; means for displaying numerical values necessary for condition setting in said second copy mode; means, which is operable only when said switch means is held in the second condition, for setting the numercial values; and means for inhibiting change of the copy modes in response to the change to the first condition from the second condition of said switch means immediately after setting of the numerical values.
Claim 6
Dependent Claim
169 words
In a copying apparatus which is capable of executing a plurality of copy modes inclusive of a first copy mode and one or more second copy modes, said apparatus comprising: switch means capable of being in a first condition and in a second condition by actuation thereof, said switch means being biased to be in the first condition; means for changing the copy mode in response to the actuation of said switch means, the change to the second copy mode from the first copy mode is effected by the change to the second condition from the first condition of said switch means; means for displaying numerical values necessary for condition setting in said second copy mode; means, which is operable only when said switch means is held in the second condition, for setting the numercial values; and means for inhibiting change of the copy modes in response to the change to the first condition from the second condition of said switch means immediately after setting of the numerical values.
