Abstract
According to a multifunction peripheral according to the present disclosure, when a DC mixing detection circuit detects that electric source power contains DC power, a DC detection signal Sdc is output from the DC mixing detection circuit. This DC detection signal Sdc is input to a solenoid of a shutoff mechanism. In response, the solenoid turns off a mechanical switch via a movable member. In addition, the DC detection signal Sdc is input to a CPU. In response, the CPU displays an error message on a display and outputs a warning sound from a speaker.
Claims8
An electrical equipment that uses alternating current (AC) power as electric source power, the electrical equipment comprising:
- a detector that detects whether the electric source power contains direct current (DC) power,
- a shutter that shuts off, when the electric source power contains the DC power, supply of the electric source power to a specific element that is inconvenient if the electric source power contains the DC power, and
- an information outputter that outputs, when the electric source power contains the DC power, predetermined information indicating that the electric source power contains the DC power, wherein
- direct or indirect supply of the electric source power to some or all of operable elements capable of operating normally is maintained even if the electric source power contains the DC power,
- the information outputter is included in the operable elements to which the direct or indirect supply of the electric source power is maintained, and
- the information outputter outputs a plurality of error messages, as the predetermined information, in a visual form one by one in sequence or randomly in a predetermined cycle.
