DATA COMMUNICATION APPARATUS, CORDLESS TERMINAL USED IN THE DATA COMMUNICATION APPARATUS THEREOF AND DATA COMMUNICATION TERMINAL USED IN THE DATA COMMUNICATION APPARATUS

摘要

The present invention relates to a data communication apparatus comprising a radio terminal 4-3 and a data communication terminal 4-1, wherein the radio terminal 4-3 transmits a signal to the data communication terminal 4-1. Internal communication means 4-3-1 for communicating, wireless communication means 2-13 for performing wireless communication, and accessory means for performing subsidiary functions of wireless communication by the wireless communication means 2-13 ( 2-9) and radio terminal control means (2-2) for controlling the radio communication means (2-13) and the accessory means (2-9); The data communication terminal 4-1 includes an internal communication means 4-1-2- for communicating a signal with the wireless terminal 4-3, and the internal communication means from the wireless terminal 4-3. Identification means (1-9) for identifying a signal received through the communication means (4-1-2), and data communication terminal control means (1-1) for controlling the data communication terminal (4-1); and; The data communication terminal 4-1 and the wireless terminal 4-3 are physically separable from each other; The data communication terminal 4-1 can perform data communication independently of the radio terminal 4-3; The data communication terminal control means 1-1 starts communication in accordance with the identification result of the signal received from the wireless terminal 4-3 through the internal communication means 4-1-2, or The radio terminal control means 2-2 responds to a signal received from the data communication terminal 4-1 via the internal communication means 4-3-1, and the accessory means 2-9. It provides a data communication device characterized in that for controlling.
