Abstract

A control apparatus according to the present invention is a control apparatus collecting data about copying machines and communicating with a centralized control unit on the basis of the collected data, including a detection device for detecting trouble occurrence on the basis of the data from the copying machines, a counter for counting the number of times the trouble occurrence in response to an output of the detection device, a calculating device for calculating a trouble occurrence frequency on the basis of the number of times of trouble occurrence while the copying machine performs copying operation for a predetermined number of times, a determination device for determining that the trouble occurrence frequency calculated by the calculating device exceeds a predetermined value, and a communication device for calling the centralized control device in response to an output of the determining device.

Claims

1. A control apparatus for collecting data related to a copying machine and communicating with a centralized control unit on the basis of the collected dam, comprising:

detecting means for detecting a trouble occurrence on the basis of data from said copying machine;

counting means for counting the number of times the trouble occurrence is detected by said detecting means;

calculating means for calculating a frequency of the trouble occurrence on the basis of the counted number of times of the trouble occurrence while said copying machine performs a predetermined number of copying processes;

receiving means for receiving a threshold value from said centralized control unit;

determining means for determining that said calculated trouble occurrence frequency exceeds said threshold value; and

communication means for calling said centralized control unit in response to an output of said determining means.

2. The control apparatus according to claim 1, wherein said trouble occurrences comprises a paper jam.

3. The control apparatus according to claim 1, wherein the data from said copying machine includes data indicating a portion of said copying machine where said trouble occurrence is detected, and said counting means counts the number of times the trouble occurrence is detected for each portion of said copying machine.

4. The control apparatus according to claim 3, wherein said calculating means calculates a frequency of the trouble occurrence for each portion of said copying machine.

5. The control apparatus according to claim 4, wherein said determining means determines that the trouble occurrence frequency exceeds a predetermined value for each portion of said copying machine.

6. The control apparatus according to claim 5, wherein said communication means transmits to said centralized control unit warning data indicating a portion of said copying machine having a trouble occurrence frequency which exceeds the predetermined value.

7. A control apparatus for collecting data related to a copying machine and communicating with a centralized control unit on the basis of the collected data, comprising:

detecting means for detecting occurrence of a paper jam and a portion of the copying machine where said paper jam occurred on the basis of data from said copy machine;

counting means for counting a number of times of paper jam occurrence in response to an output of said detecting means for each portion of said copying machine;

calculating means for calculating an occurrence frequency of paper jams for each portion of said copying machine on the basis of the counted number of times of paper jams occurrence in each portion of said copying machine while said copying machine performs a predetermined number of copying processes;

receiving means for receiving a threshold value for each portion from said centralized control unit;

determining means for determining if an occurrence frequency at each portion of said copying machine calculated by said calculating means exceeds said threshold value for each portion of said copying machine; and

communication means for calling said centralized control unit in response to an output of said determining means and for transmitting data including a portion of said copying machine having an occurrence frequency which exceeds said threshold value to said centralized control unit.

8. A control apparatus which collects data from a copying machine and communicates, based on the collected data, with a centralized control unit located at a remote site through a communication network comprising:

receiving means for receiving information from said copying machine;

first determination means, responsive to said information received by said receiving means, for determining an occurrence of a problem associated with said copying machine;

second determination means, responsive to said information received by said receiving means, for determining a recovery for the problem;

a communication device which is connected with said communication line to call said centralized control unit and to transmit a problem indication thereto; and

controlling means for activating said communication device to call said centralized control unit when a problem is first determined by said first determination means and for forbidding said communication device to call the centralized control unit when the same problem is determined by said first determination means until said second determination determines the recovery for the problem.

9. A system including a copying machine and a control apparatus which collects data from said copying machine and communicates, based on the collected data, with a centralized control unit located at a remote site through a communication network comprising:

a communication device which is provided on said control apparatus to call said centralized control unit when a problem occurs in said copying machine;

determination means liar determining that connection with said centralized control unit cannot be made after a predetermined number of attempts;

an operation panel which is provided to said copying machine to allow an operational input;

a message display which is located on said operation panel to display a predetermined message indicating disconnection between said control apparatus and said centralized control unit in response to an output of said determination means; and

means for changing said predetermined message based upon a location in said communication network at which said control apparatus and said centralized control unit are disconnected.

10. A control apparatus which collects data from a copying machine and communicates, based on the collected dam, with a centralized control unit located at a remote site through a communication line, the control apparatus comprising:

an interface through which data from said copying machine is received by said control apparatus and through which data is transmitted from said control apparatus to said copying machine;

a connector which connects said interface with said copying machine;

a communication device which is connected by said communication line to said centralized control unit; and

determination means for determining whether said connector is properly connected with said interface and said copying machine; and

means for activating said communication device in response to an output of said determination means.
