用の感温素子を電源入力線路に設け、電源スイツ
チの切換動作に基づいて所定の電源を投入する電
源回路において、 上記電源スイツチがオフ操作された後、所定の
時間が経過してから上記電源スイツチがオン操作
されたとき直ちに上記電源を投入し、 上記電源スイツチがオフ操作された後、所定の
時間が経過するまでの間に上記電源スイツチがオ
ン操作されると、当該オン操作の後所定時間が経
過してから上記電源を投入する ことを特徴とする電源回路。[Scope of Claim for Utility Model Registration] In a power supply circuit in which a temperature-sensitive element for inrush current limiting whose resistance value decreases as the temperature rises is provided in the power input line, and a predetermined power is turned on based on the switching operation of a power switch, When the power switch is turned on after a predetermined time has elapsed after the power switch is turned off, the power is turned on immediately, and until a predetermined time has elapsed after the power switch is turned off. If the power switch is turned on during this period, the power is turned on after a predetermined period of time has elapsed after the turn-on operation.
