Abstract

PURPOSE:To obtain a display device which is capable of executing an accident display operation exactly against an instantaneously passing overcurrent, and resets automatically after a constant interval of time, by providing each specific current detecting part, display driving part and driving transfer mechanism part. CONSTITUTION:This display device is provided with a current detecting part A placed so as to enclose an electric wire, a display driving part B which is turned, energizing an energizing member when an overcurrent has been detected by said detecting part A, and a driving transfer mechanism part H for operating the display device by being interlocked only in case of the resetting operation of the display driving part B by energizing force of said energizing member. For instance, the display driving part B is constituted of a rectifier 6, a variable resistance R, a capacitor C, a trigger diode TD, a relay X, its (a) contact Xa and a rotary solenoid RS, and the energizing member consists of a reset spring S for resetting an output shaft provided in the rotary solenoid RS. Also, the driving transfer mechanism part H is constituted of gear mechanisms 7, 10, an operating lever 14, a turning member 11 for driving the display device, and others.
