Abstract
PURPOSE: To reproduce display in case of the generation of a trouble when a power source is again made to a display device even if the power source is disconnected, by mounting a no-power holding circuit for holding detector output even if the power source is broken and a display portion for indicating the output.
CONSTITUTION: When a relay 43 is operated, the contact 45 is brought to broken condition, and a power source is supplied to a coil 53. When the supply of the power source of a coil 52 is broken and the power source is fed to the coil 53, an armature 54 is released from a pole piece 55 in a two winding latch relay 42, and the relay 42 is put to a recovery condition. When the two winding latch relay 42 is recovered, the contact 47 is opened, and a display lamp 38 is also put out. Thus, a holding circuit is provided with a no-power self-holding function so that a display condition just before breaking the power source can be reporduced if again making the power source even when the power source of a display portion 37 is disconnected due to some cause during time up to the time of putting-out from the time of lighting of the lamp.
