Abstract
An electronic apparatus is capable of minimizing the increase in the capacity of a non-volatile memory provided in the wireless tag and of minimizing the increase in the time required for reading data. A sub unit such as a lid includes a wireless tag therein is detachably attached to an accommodating section such as a main body of the electronic apparatus. A reader-and-writer unit is housed in the accommodating section. When the sub unit is positioned in place in the accommodating section, the reader-and-writer unit communicates with the wireless tag to read data from the wireless tag and write data into the wireless tag. An anticipation signal generator provides an anticipation signal to the reader-and-writer unit when communication between the wireless tag and the reader-and-writer unit is anticipated to fail. The reader-and-writer unit is prevented from communicating with the wireless tag in accordance with the anticipation signal.
