An oscillation circuit comprises an oscillator, further comprising a resonance frequency, an amplifier that is connected to the oscillator, an energized pulse emission unit, which emits a pulse of a frequency, from among the resonance frequency, which falls within a given range, a switching unit, which switches between the energized pulse emission unit being connected to, and disconnected from, the oscillator and the amplifier, and an operation instruction unit, which issues an instruction signal to the energized pulse emission unit to commence operating, wherein the switching unit connects the oscillator and the energized pulse emission unit during an interval that commences at the time that the operation instruction unit issues the operation instruction, the interval comprising one cycle, half a cycle, or a plurality of cycles of pulses that the energized pulse emission unit emits. |
