<p>PROBLEM TO BE SOLVED: To simplify the constitution of a power source and to eliminate the generation of mechanical sound even when the clock display is performed while the system operation is stopped. SOLUTION: When the power source is turned ON by a receiver 10A in the OFF state of power, a system power source part 19 is controlled by a control part 16A, and the command of power ON is outputted, after a system power VSYS is started and supplied to a CD player 30A. In the CD player 30A, when the VSYS is started, a control part 32A becomes the standby state, and the specified initial set control is carried out with respect to a CD reproducing part 31 at the point of time when the command of power ON is inputted. When the operation requesting the clock display is made by the receiver 10A during the OFF state of power, the system power source part 19 is controlled by the control part 16A, and the VSYS is temporarily started and supplied to a display part 14 to display the data and time. At this time, the VSYS is supplied to also the CD player 30A, but only the control part 32A becomes the standby state, and no initial set control is made with respect to a CD reproducing part 31.</p> |
