Abstract
When a mobile data communication device is rocked due to an input/output operation, a rotary shaft of a generator coupled with a weight is rotated, and power is generated. The generated power is stored in a capacitor. The power stored in the capacitor is controlled to constant voltage by a voltage stabilizing circuit and is supplied to a control circuit. In the control circuit, based on information inputted in a pointing device by supplied power, data are transmitted and received with an external data processing device through an infrared data transmitting/receiving device. Alternatively, power may be supplied from the outside of the mobile data communication device by electromagnetic induction. According to the above-mentioned configuration, not using a battery or a wire system, the mobile data communication device is capable of easily supplying power.
