Abstract
A portable information device includes a portable main part having a clocking function, a source part which is detachably attachable to the main part and contains secondary batteries serving as a power source for the main part, and a charger which is separate from the main part and serves to charge the source part. The charger includes a clock part for setting time, and the information device is adapted to cause time data from the clock part to be transmitted to the source part when the source part is charged by the charger and, when the source part is attached to the main part, to transmit time data updated by the source part to the main part and to thereafter cause the main part to continue updating the time data.
