ENDLESS UNIDIRECTIONAL DOCUMENT COMMUNICATION SYSTEM

PURPOSE:To enable a series of nonaudio system information to be received only for one time by detecting an instruction to start reception, detecting and storing an information additional number outputted first, comparing a stored information additional number with a received information additional number, and completing the reception when they coincide. CONSTITUTION:The system is provided with a nonaudio system transmitter 2 equipped with a means PBOSC which accumulates plural nonaudio system information in a MEM after attaching the information additional number on each of them, and a means 21 which returns the information additional number to a first number at the last stage. Meanwhile, it is comprised of a nonaudio system information receiver 3 equipped with the MEM which detects and stores the information additional number 5 of the nonaudio system information outputted first when the reception is started and the nonaudio system information is received, and a means MPU 31 which compares the stored information additional number 5 with a received information additional number and completes the reception when they coincide. In such a way, the endless transmission of the nonaudio system information can be performed at a transmission side, and the reception of a series of non-audio system information can be performed only for one time at a reception side.
