Abstract
A data communication apparatus connectable to a line having a plurality of communication channels or to a plurality of lines comprises: multi-address transmission means for transmitting document sheet information to a plurality of destinations through the plurality of communication channels or the plurality of lines. The multi-address transmission means starts the multi-address transmission to a second destination through one of the communication channels or the lines a predetermined time after the start of the multi-address transmission to a first destination through other one of the communication channels or the lines.
Claims7
A data communication apparatus connectable to a line having a plurality of communication channels or to a plurality of lines, comprising:
- multi-address transmission means for transmitting document sheet information to a plurality of destinations through said plurality of communication channels or said plurality of lines;
- said multi-address transmission means starting the multi-address transmission to a second destination through one of said communication channels or said lines a predetermined time after the start of the multi-address transmission to a first destination through another one of said communication channels or said lines.
A communication method in a data communication apparatus connected to a line having first and second channels, comprising;
- a first transmission step for transmitting data to a first destination through the first channel;
- a first timer step for starting a first timer in response to the start of transmission of the data in said first transmission step;
- a decision step for determining whether a first predetermined time is counted in said first timer step;
- and
- a second transmission step for transmitting data to a second destination through the second channel when the time-out of the first predetermined time is detected in said decision step.
A communication method according to claim further comprising:
- a second timer step for starting a second timer after the completion of the transmission of the data is said first transmission step;
- and
- a third transmission step for transmitting data to a third destination through the first channel when the time-out of a second predetermined time is detected in said second timer step.
