  • Abnormality display device including a switch to control a display element to indicate abnormal or normal operations for plural systems
    Patent number: 9817461
    Abstract: An abnormality display device for an electronic apparatus includes power source circuits (1) each being used inside systems of the electronic apparatus and generating each of system voltages, a voltage monitoring circuit (2) that turns on an input power source of the electronic apparatus and detects whether each system voltage normally rises up before the electronic apparatus rises, display elements (6b to 6d) that show whether an abnormality occurs in any of the system voltages through input of a signal from the voltage monitoring circuit (2), and switching elements (5a to 5c) in which a switching signal is input after each system voltage rises. The switching signal switches the display elements from a display mode used to show the abnormality of each system voltage to a display mode other than the display mode used to show the abnormality of each system voltage.
