Abstract

An equipment control apparatus in a system having an input unit for entering data on the conditions of equipment from the equipment, a communication unit for communicating with the apparatus located at a distance, and a control unit for exerting control in such a way as to transmit the data to the apparatus located at a distance through the steps of interrupting communication once on receiving a call from the apparatus requesting the data and then calling the apparatus located at a distance via the communication unit.

Claims

1. A data communication apparatus comprising:

input means communicating with an image forming apparatus for inputting data from the image forming apparatus;

memory means for storing the data input by said input means;

communication means communicating with an external apparatus located at a remote location and for transmitting the data stored in said memory means to the external apparatus; and

control means for controlling operation of said input means, memory means and communication means, said control means controlling said input means to input the data from the image forming apparatus and controlling said memory means to store the input data when said communication means receives a request for data communication from the external apparatus, said control means controlling said communication means to disconnect a communication with the external apparatus when said communication means receives a request for data communication from the external apparatus, then controls said communication means to connect a communication with a predetermined external apparatus, and subsequently controls said communication means to transmit the data stored in said memory means to the predetermined external apparatus.

2. A data communication apparatus as claimed in claim 1, wherein said image forming apparatus is a copier.

3. An apparatus according to claim 1, further comprising determining means for determining whether or not a request for data communication is received.

4. An apparatus according to claim 1, further comprising storage means for storing information designating the predetermined external apparatus to which the data is transmitted by said communication means.

5. A data communication method for a data communication apparatus which communicates with an external apparatus located at a location remote from the data communication apparatus, the data communication apparatus being connected to an image forming apparatus, said method comprising the steps of:

receiving a request for data communication from the external apparatus;

disconnecting a communication with the external apparatus;

connecting a communication with a predetermined external apparatus;

inputting data from the image forming apparatus, when the request for data communication is received from the external apparatus;

storing the data input from the image forming apparatus in said inputting step; and

transmitting the data stored in said storing step to the predetermined external apparatus connected to the data communication apparatus in said connecting step.

6. A method according to claim 5, further comprising the step of determining whether or not a request for data communication is received.

7. A method according to claim 5, further comprising the step of storing information designating the predetermined external apparatus to which the data is transmitted.

8. A data communication method in a system comprising a data communication apparatus and an external apparatus located at a location remote from the data communication apparatus, the data communication apparatus being connected to an image forming apparatus, said method comprising the steps of:

transmitting a request for data communication from the external apparatus to the data communication apparatus;

determining whether or not there is a request for data communication at the data communication apparatus;

disconnecting a communication between the data communication apparatus and the external apparatus when said determining step determines that there is a request for data communication;

connecting a communication between the data communication apparatus and a predetermined external apparatus;

inputting data from the image forming apparatus when said determining step determines that there is a request for data communication;

storing the data input from the image forming apparatus in said inputting step; and

transmitting the data stored in said storing step from the data communication apparatus to the predetermined external apparatus connected to the data communication apparatus in said connecting step.

9. A method according to claim 8, further comprising the step of storing information designating the predetermined external apparatus to which the data is transmitted.
