Abstract

PURPOSE: To reduce the power consumption by connecting a power supply circuit of a large-volume bell to a DC power source through a switching element and supplying power only at the time of the presence of a start signal. CONSTITUTION: When there is not a signal between terminals 11 and 12 of a reception unit 1, an inverter 1A is in the waiting state, and an oscillation unit 2 consisting of oscillation circuits 17 to 19 is in the non-operating state, and an amplifier 22 of a preamplifier unit 3 is in the waiting state. Therefore, a current flowing to power lines 27 to 29 is small, and the voltage drop of a resistance 24 is small, and therefore, a transistor TR 30 is in the turned-off state. when a signal is applied to terminals 11 and 12, the inverter 1A is operated, and units 2 and 3 are set to the operating state. Consequently, the power consumption is reduced because the power supply circuit of a circuit part where the power consumption is relatively large is controlled.
