    • A facsimile apparatus and a facsimile communication method prevent the termination of communication in error due to memory capacity shortage when confidential communication or relay designation communication is effected by using a sub-address additionally recommended by the CCITT/T.30. When a remaining capacity of an image memory is smaller than a preset threshold, sub-address control information representing the invalidity of the sub-address is stored in sub-address control memory means. As a result, when an initial identification signal or a send command signal is sent to a destination station, a bit indicating that the sub-address is valid is sent without being set. Namely, the invalidity of the sub-address function is informed to the destination station. Thus, the confidential reception or the relay designation reception using the sub-address is not accepted and the termination of the communication in error due to the memory capacity shortage is avoided.
    • 当通过使用CCITT / T.30另外推荐的子地址来进行机密通信或中继指定通信时,传真机和传真通信方法由于存储器容量不足而导致通信错误终止。 当图像存储器的剩余容量小于预设阈值时,表示子地址无效的子地址控制信息存储在子地址控制存储装置中。 结果,当向目标站发送初始识别信号或发送命令信号时,发送指示子地址有效的位而不被设置。 即,子地址功能的无效被通知给目的地站。 因此,不接受使用子地址的机密接收或中继指定接收,并且避免了由于存储器容量不足而导致的错误通信的终止。
