Abstract
Abstract A control apparatus according to the present invention is a control apparatus collecting data related to copying machines and communicating with a centralized control unit on the basis of the data collected, including a communication device for calling the centralized control unit, a determination device for determining that connection with the centralized control device can not be made in spite of the fact that the communication device is activated, a setting device for setting a retransmission time on the basis of a random number in a predetermined time period in response to a determination output of the determination device, a timer device for counting the present time, and a control device for having the communication device call the centralized control unit again when the present time becomes the retransmission time.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
173 words
A control apparatus collecting data related to a copying machine and communicating with a centralized control unit on the basis of the collected data, comprising: communication means for calling said centralized control unit; first control means for activating said communication means when a predetermined transmission condition is satisfied, said predetermined transmission condition including one with high priority and one with low priority; determination means for determining that connection with said centralized control unit cannot be made in spite of the fact that said communication means is activated; differentiating means for differentiating a priority of said predetermined transmission condition in response to an output of said determination means; setting means for setting retransmission time on the basis of a random number from a predetermined time period when it is differentiated by said differentiating means that the priority of said predetermined transmission condition is low; timer means for counting the present time; and second control means for having said communication means call said centralized control unit again when the present time becomes the redialing time.
Claim 2
Dependent Claim
173 words
A control apparatus collecting data related to a copying machine and communicating with a centralized control unit on the basis of the collected data, comprising: communication means for calling said centralized control unit; first control means for activating said communication means when a predetermined transmission condition is satisfied, said predetermined transmission condition including one with high priority and one with low priority; determination means for determining that connection with said centralized control unit cannot be made in spite of the fact that said communication means is activated; differentiating means for differentiating a priority of said predetermined transmission condition in response to an output of said determination means; setting means for setting retransmission time on the basis of a random number from a predetermined time period when it is differentiated by said differentiating means that the priority of said predetermined transmission condition is low; timer means for counting the present time; and second control means for having said communication means call said centralized control unit again when the present time becomes the redialing time.
Claim 3
Dependent Claim
29 words
The control apparatus according to claim 1, wherein said predetermined transmission condition with low priority is satisfied when the present time comes to a predetermined time set in advance.
Claim 4
Dependent Claim
20 words
The control apparatus according to claim 1, wherein said transmission condition with high priority is satisfied when a trouble occurs.
Claim 5
Dependent Claim
45 words
The control apparatus according to claim 1, further comprising second setting means for setting a retransmission time which is a predetermined time period after the present time when it is decided by said differentiating means that the priority of said predetermined transmission condition is high.
Claim 6
Dependent Claim
180 words
A control apparatus collecting data related to a copying machine and communicating with a centralized control unit on the basis of the collected data, comprising: communication means for calling said centralized control unit; first control means for activating said communication means when a predetermined transmission condition is satisfied, said predetermined transmission condition including one with high priority and one with low priority; determination means for determining that connection with said centralized control unit can not be made in spite of activation of said communication means; second control means for having said communication means call said centralized control unit again in response to an output of said determining means; differentiating means for differentiating the priority of said predetermined transmission condition; deciding means for deciding that the number of times of calling said centralized control unit of said communication means controlled by said second control means exceeds a predetermined calling number of times corresponding to priority of said predetermined transmission condition; and third control means for forbidding operation of said second control means in response to an output of said decided means.
Claim 7
Dependent Claim
180 words
A control apparatus collecting data related to a copying machine and communicating with a centralized control unit on the basis of the collected data, comprising: communication means for calling said centralized control unit; first control means for activating said communication means when a predetermined transmission condition is satisfied, said predetermined transmission condition including one with high priority and one with low priority; determination means for determining that connection with said centralized control unit can not be made in spite of activation of said communication means; second control means for having said communication means call said centralized control unit again in response to an output of said determining means; differentiating means for differentiating the priority of said predetermined transmission condition; deciding means for deciding that the number of times of calling said centralized control unit of said communication means controlled by said second control means exceeds a predetermined calling number of times corresponding to priority of said predetermined transmission condition; and third control means for forbidding operation of said second control means in response to an output of said decided means.
Claim 8
Dependent Claim
39 words
The control apparatus according to claim 5, wherein said predetermined number of times of calling includes a first value for a predetermined transmission condition with high priority and a second value for a predetermined transmission condition with low priority.
Claim 9
Dependent Claim
23 words
The control apparatus according to claim 6, wherein said first value of said predetermined times of calling is larger than the second value.
Claim 10
Dependent Claim
28 words
The control apparatus according to claim 5, wherein said predetermined transmission condition with low priority is satisfied when the present time becomes a predetermined time set in advance.
Claim 11
Dependent Claim
20 words
The control apparatus according to claim 5, wherein said transmission condition with high priority is satisfied when a trouble occurs.
Claim 12
Dependent Claim
32 words
The control apparatus according to claim 5, wherein said second control means comprises setting means for setting a retransmission time on the basis of a random number from a predetermined time period.
Claim 13
Dependent Claim
29 words
The control apparatus according to claim 5, wherein said second control means comprises setting means for setting a predetermined time period after the present time as a retransmission time.
