1. An electronic apparatus, comprising:
- a radio communication apparatus including a radio communication section for executing radio communication with a RF tag, and a controller for controlling the radio communication section;
a main controller which is capable of communication with the controller and which controls the radio communication apparatus;
first diagnostic means for executing a first diagnostic process in which the main controller transmits a command to the controller of the radio communication apparatus requesting a reply from the controller of the radio communication apparatus, and then determining whether a radio communication status between the main controller and the radio communication apparatus is abnormal depending on whether the main controller receives the reply from the controller of the radio communication apparatus; and
second diagnostic means for executing a second diagnostic process in which the main controller transmits a radio communication run command to the controller of the radio communication apparatus for communicating with the RF tag, and then determines whether a radio communication status between the radio communication apparatus and the RF tag is abnormal depending on whether the main controller receives a reply from the RF tag a reply received from the controller of the radio communication apparatus about the RF tag.

Abstract
An electronic apparatus having a RF tag communication function is provided which includes a RF tag reader/writer and a main controller for controlling the RF tag reader/writer. The RF tag reader/writer includes a radio communication section for executing radio communication with a RF tag and a controller for controlling the radio communication section. The main controller is capable of communication with the controller. A command which requests a reply is transmitted from the main controller to the RF tag reader/writer, and the controller is diagnosed based on the reply from the RF tag reader/writer.
