Data communication apparatus which transmits in accordance with a reception time zone or a terminal from which data has been received
First Claim
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, andwhen 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.

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.

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. - View Dependent Claims (8, 9, 10, 11, 12)

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. - View Dependent Claims (14, 15, 16, 17, 18)
