PURPOSE:To prevent the characteristic of a disc player from deterioration due to clock interference and to attain pinch control by using a direct signal or a frequency divided signal outputted from a reference clock oscillation source or a variable clock oscillation source for all clock sources necessary for respective parts of a system. CONSTITUTION:A digital signal processing means 11 processes a digital signal reproduced from a disc, and a D/A convertion means 13 converts the processed digital signal into an analog signal. A system control means 17 controls a system. A clock signal from a single reference clock oscillation source 19 or a clock signal from a single variable clock oscillation source 23 is switched and the switched clock signal is supplied to means 11, 13, and 17 directly or after dividing its frequency. |
