Abstract
An electronic device does not carry out control operation corresponding to a signal from an operation button which is kept in pressed state when electric power is supplied. When electric power is supplied, the voltage changing depending on open and closed state of switches SW to SW corresponding to operation buttons to be manipulated is judged to be a specified value or not. When the voltage is not judged to be specified value, the control unit does not carry out control operation corresponding to the signal from the operation button that has been in pressed state.
