Abstract

A data communication apparatus performs relay multi-address communication of received data with another predetermined data communication apparatus designated in advance. The apparatus includes a determining unit for determining whether a current communication or a communication to be executed satisfies a predetermined condition, and a control unit for performing relay multi-address communication of the received data to another data communication apparatus designated in advance independent of any action at the transmitting end. In three advantageous embodiments, the apparatus can set a time zone for data transmission, transmit data to a plurality of destination stations and set a transmission mode. The apparatus determines whether data will be relayed based upon the time zone in which the data was received or upon the identity of the source terminal.

Claims

1. A data communication apparatus comprising:

receiving means for receiving data from a transmitter station via a first communication line;

transmitting means for transmitting data to destination station via a second communication line;

a clock;

controlling means connected to said clock for controlling said transmitting means to transmit the data received by said receiving means, wherein said controlling means detects a receiving time at which said receiving means receives data in accordance with an output of said clock, and determines whether or not to cause said transmitting means to transmit the data received by said receiving means in dependence on the receiving time; and

time zone setting means for setting a time zone having a start time and an end time,

wherein when the receiving time is after the start time and before the end time so as to be within the time zone set by said time zone setting means, said control means causes said transmitting means to transmit the received data, and

when the receiving time is not within the time zone, said control means does not cause said transmitting means to transmit the received data in dependence on the receiving time.

2. An apparatus according to claim 1, wherein said data is image data.

3. A data communication apparatus according to claim 1, further comprising recording means for recording data, wherein when the receiving time is not within the time zone set by said time zone setting means, said recording means records the received data.

4. An apparatus according to claim 1, wherein said control means causes said transmitting means to transmit the received data to a plurality of destination stations.

5. An apparatus according to claim 4, further comprising memory means for storing the received data, wherein said transmitting means transmits the data stored in said memory means.

6. An apparatus according to claim 1, further comprising destination designating means for designating in advance at least one destination to which data is to be sent in response to an instruction of an operator, wherein said transmitting means transmits data to each destination designated by said designating means.

7. A data communication apparatus comprising:

receiving means for receiving data from a transmitter station via a first communication line;

transmitting means for transmitting data received by said receiving means to a destination station via a second communication line;

detecting means for detecting a station which transmitted the data received by said receiving means;

setting means, responsive to a manual instruction of an operator, for setting a predetermined station; and

control means for comparing the detected transmitter station with the predetermined station and for controlling said transmitting means to transmit the received data to the destination station when a comparison result of the control means indicates that the detected transmitter station corresponds to the predetermined station.

8. An apparatus according to claim 7, wherein said transmitting means transmits the received data without interruption after entry of the instruction by the operator.

9. An apparatus according to claim 7, wherein said data is image data.

10. An apparatus according to claim 7, wherein said transmitting means transmits the received data to a plurality of destination stations.

11. An apparatus according to claim 10, further comprising memory means for storing the received data, wherein said transmitting means transmits the data stored in said memory means.

12. An apparatus according to claim 7, further comprising destination designating means for designating in advance at least one destination to which data is to be sent, in response to an instruction of an operator, wherein said transmitting means transmits data to each destination designated by said designating means.

13. A data communication method comprising the steps of:

receiving data from a transmitter station via a first communication line;

transmitting data to a destination station via a second communication line;

controlling said transmitting step to transmit the data received by said receiving step, wherein said controlling step detects a receiving time at which said receiving step receives data in accordance with an output of a clock, and determines whether or not to cause said transmitting step to transmit the data received by said receiving step in dependence on the receiving time; and

setting a time zone having a start time and an end time,

wherein when the receiving time is after the start time and before the end time so as to be within the time zone set by said time zone setting step, said control step causes said transmitting step to transmit the received data, and when the receiving time is not within the time zone, said control step does not cause said transmitting step to transmit the received data in dependence on the receiving time.

14. A method according to claim 13, wherein said data is image data.

15. A method according to claim 13, further comprising a step of recording data, wherein when the receiving time is not within the time zone set by said time zone setting step, said recording step records the received data.

16. A method according to claim 13, wherein said control step causes said transmitting step to transmit the received data to a plurality of destination stations.

17. A method according to claim 16, further comprising a step of storing the received data, wherein said transmitting step transmits the data stored in said storing step.

18. A method according to claim 13, further comprising designating in advance at least one destination to which data is to be sent in response to an instruction of an operator, wherein said transmitting step transmits data to each destination designated by said designating step.

19. A data communication method comprising the steps of:

receiving data from a transmitter station via a first communication line;

transmitting data received by said receiving step to a destination station via a second communication line;

detecting a station which transmitted the data received by said receiving step;

responsive to a manual instruction of an operator, setting a predetermined station;

comparing the detected station with the predetermined station; and

controlling said transmitting step to transmit the received data when a comparison result of the control step indicates that the detected transmitter station corresponds to the predetermined station.

20. A method according to claim 19, wherein said transmitting step transmits the received data without interruption after entry of the instruction by the operator.

21. A method according to claim 19, wherein said data is image data.

22. A method according to claim 19, wherein said transmitting step transmits the received data to a plurality of destination stations.

23. A method according to claim 22, further comprising storing the received data, wherein said transmitting step transmits the data stored in said storing step.

24. A method according to claim 19, further comprising designating in advance at least one destination to which data is to be sent, in response to an instruction of an operator, wherein said transmitting step transmits data to each destination designated by said designating step.
