    摘要: A power source control apparatus controls a power source of a display unit of a system which includes an input device and a computer body. The power source control apparatus includes a first part for detecting an input signal which is output from the input device and for turning ON the power source of the display unit based on the detection of the input signal in a state where the power source is OFF, a second part for turning OFF the power source of the display unit if the first part detects no input signal for a predetermined time, and a third part for transmitting to the computer body second and subsequent input signals detected by the first part, so that the power source of the display unit is automatically turned ON in response to the input signal from the input device, but only the second and subsequent input signals are transmitted to the main body. In other words, the first input signal is blocked and is not transmitted to the main body, so that the state of the main body at the time when the power source of the display unit is turned ON is correctly displayed on the display unit.

A single smoothing capacitor is connected in parallel to the electric vehicle drive source so that the respective drive elements of the plurality of DC-DC converter units are driven by the control circuit at different timings.
