摘要

PROBLEM TO BE SOLVED: To miniaturize a portable terminal equipment and to relax the restriction on directivity in radio communication in a system executing radio communication between an installation-type computer connected to a network and a portable terminal equipment and using information resources provided in the network. SOLUTION: The system is provided with the portable information processing unit 200, the first installation type information processing unit to (2) and the second information processing unit 100 (1) which are installed in prescribed places and are connected to the network 500 providing information resources and a data base 400 which can be accessed by the first and second installation-type information units 100 (2) and 100 (1) and is connected to the network 500. In such a case, a prescribed information is transmitted to the first and second installation-type information processing units 100 (2) and 100 (1) from the portable information processing unit 200 by unidirectional radio communication and information resources displayed on the first installation-type information processing unit 100 (2) is displayed again on the second installation-type information processing unit 100 (1) afterwards.
