低待機電力の回路構成
Document Type and Number:
Japanese Patent JP5640688
Kind Code:
B2
Abstract:
This circuit device comprises: a rectifying/smoothing power source unit for outputting a primary power source; an electric power conversion section of which the start up and the termination can be achieved by switching the electric conduction of the primary power source and which can output a secondary power source, which can utilize one side of the primary power supply source as a common potential, through the electric power conversion using the primary power source as an electric power source when the electric power conversion section is driven; an electric power conversion section which outputs the secondary power source through the electric power conversion using the primary power source as an electric power supply source; and a function control section which controls the action of the device by the output from the electric power conversion section and is equipped with an input terminal capable of detecting the change in voltage based on the electric conduction of the secondary power source. The circuit device additionally comprises: an operation switch which is so arranged as to be connected between the common potential and the electric power conversion section and between the common potential and an input terminal of the function control section and is equipped with a normal-open-type single-pole/single-throw contact which can switch between the electric conduction of the primary power source and the electric conduction of the secondary power source; an electric conduction switch section which is so arranged as to be connected between the common potential and the electric power conversion section and can switch the electric conduction of the primary power source; and a voltage change blocking section which is arranged between the electric power conversion section and the input terminal of the function control section and can block the voltage of the primary power source. The function control section is so adapted as to be run upon the electric conduction of the secondary power source and judges the action of an operation switch to control the operation of a device assigned to an operation switch.
