ABSTRACT:
To drive an oscillator always at a stable and constant oscillation even if frequency and amplitude of a power supply voltage differ depending on a delivery destination of the oscillator, an oscillator drive control device (10), which generates a predetermined switching pattern by operating a switching element, and supplies an oscillation generation unit (7) of the oscillator with drive electric power for generating predetermined oscillation frequency and amplitude according to the switching pattern, includes: a voltage detection circuit (11) for detecting a power supply voltage unique to a delivery destination of the oscillator; a memory circuit (12) storing, in advance, a basic switching pattern adapted to an arbitrarily set reference voltage, and used for driving the oscillation generation unit (7) at proper oscillation frequency and amplitude; and an arithmetic processing circuit (13) for calculating a ratio of the detected voltage unique to the delivery destination detected by the voltage detection circuit (11) to the reference voltage, and calculating, based on the ratio, a switching pattern substantially the same as the basic switching pattern under an environment of the power supply voltage unique to the delivery destination.
