In ') i, a constant 'P1, voltage generated by the reference voltage generating means l is compared with the power supply 70'r11. River, and if 'r1i, the source voltage is above a certain voltage JJh, the green color The light emitting element jIK driving means 3 is operated to turn on the green light emitting element 5. 71a. When the pressure ↑I of the source 7 decreases to a preset value of ?1iLL, the green light emitting element driving means 3 and The red light emitting element driving means 4 is operated simultaneously to light up the green and red light emitting elements 5 and 6 at the same time.

１１． ＩＪＥ以下に低下していることを表示する。The output 1b of the pond 17 and the pressure are divided by resistors 18 and 19 and added. As long as the power receiving (the sum and pressure of the dry batteries 17 supplying power to the display unit 8 is sufficiently large, the comparator 12 connected to the pace of the transistor 13 that drives the green light emitting element 5 The output of 2, the first one, is connected to the base of the transistor 14 which drives the red light-opening element 6.
Since the output 11t5 pressure ↓9 is in a low state, and the base emitter ilj, H:e of the transistor 13 is in a low state, the green light-emitting wire 5 of the collector circuit of the transistor 13 is lights up. On the other hand, Tranzine 14
0 base and emitter (well, driven by the small first output voltage of the comparator 12), the red light emitting element 6 connected to the collector circuit of the transistor 14 does not light up. When the voltage of the comparator 17 decreases and the mJ and second output of the comparator 12 are the same, the green and red light emitting elements 5 and 6 light up together with the light output of medium culm. ] When output 1 of 7 also falls below 5 voltage (the lowest pressure I, which is inevitable for the normal operation of display unit B), the 1st output of comparator 12 is turned off. Since the second output is a small value, the green light emitting element 15 goes out and only the red light emitting element 6 lights up 7'.
Indicates that the dry 1 (1, output 11 of pond 17) 1 pressure has decreased below the minimum limit 11.IJE above.
