This invention allows completely cutting power supply to a circuit that has become dysfunctional because of blowout of a fuse. To accomplish this, a circuit includes a fuse connected to one supply line of an AC power supply, a switching unit connected to the other supply line of the AC power supply, a detection unit configured to detect blowout of the fuse, and a control unit configured to turn off the switching unit when the detection unit detects blowout of the fuse. |
