| 1. A radio communication system that performs a radio communication between a stationary information device and a mobile terminal
device, wherein
the stationary information device includes
a first radio communication unit that performs a radio communication to detect an approach between the stationary information
device and the mobile terminal device, the first radio communication unit including a detecting unit that detects the approach
between the stationary information device and the mobile terminal device based on a result of the radio communication by the
first radio communication unit; and
an attracting unit that generates, when the detecting unit detects the approach between the stationary information device
and the mobile terminal device, an attraction force for attracting and fixing the mobile terminal device, and
the mobile terminal device includes
a second radio communication unit that performs the radio communication with the first radio communication unit of the stationary
information device; and
an attracted unit that is attracted to the attraction force generated by the stationary information device.
