Title:
OSCILLATOR
Document Type and Number:
Japanese Patent JPH07273543
Kind Code:
A
Abstract:
PURPOSE: To attain stable oscillation even when any power supply is employed, to decrease oscillation start time and to reduce current consumption.
CONSTITUTION: This oscillator is provided with a timer means 6 operated in interlocking with start of power of a power supply means 1 and with power supply changeover means 7, 8 replacing a power supply of an oscillation means 5 with an output power of a constant voltage means 4 by a voltage conversion means 2, and an output power from the voltage conversion means is supplied to the oscillation means at application of power. Then the output power from the constant voltage means is supplied to the oscillation means after the lapse of a prescribed time.
