Abstract
An oscillation device, includes: an oscillator circuit that generates an oscillation signal based on a direct current voltage to be inputted, the oscillation signal being provided with a specification requested by a supplied device that is supposed to receive a supply of the oscillation signal; a gate circuit provided in the subsequent stage of the oscillator circuit and capable of outputting the oscillation signal from the oscillator circuit towards the supplied device; a power supply monitor circuit for detecting that the direct current voltage to be inputted has reached a voltage at which the oscillator circuit is able to start to generate the oscillation signal; and a delay circuit that causes the gate circuit to output to the supplied device the oscillation signal from the oscillator circuit, when a time required for the state of the oscillation signal, which the oscillator circuit generates, to become substantially constant is clocked on the basis of a time when a notice of the detection is received from the power supply monitor circuit, and the clocking is completed.
