雑になつていた。 In fields such as watches and calculators, there are devices that have a function that predicts the lifespan of batteries used as power sources, but conventionally, the battery voltage drop is detected using a pure electric circuit, and when the voltage drops to a certain value, To,
For example, if the buzzer is activated or the second hand is
The battery was incremented by 2 seconds every second to warn the user that the battery was nearing the end of its life and to prompt the user to replace the battery. As a result, electrical circuits became complicated.

長穴である。 In the embodiment shown in the accompanying drawings, the stator 1 is composed of a plate 2 and a plate 3, the plate 3 is connected to both ends of the plate 2, and a bobbin 5 around which a coil 4 is wound is inserted through the plate 2. ing. Two pairs of stator magnetic poles 6a, 6b and 7a, 7b are formed on the plate 3. Although the stator magnetic poles 6a and 6b, 7a and 7b are mechanically connected together through the narrow width parts 8 and 9, the magnetic resistance is large in the narrow width parts 8 and 9, so the magnetic is essentially equivalent to being divided by these parts. Further, a pair of notches 10 and 11 are formed in each set of stator magnetic poles 6a and 6b, and 7a and 7b to face each other. Therefore, due to the presence of the notches 10 and 11, the main rotor 1 is rotatably inserted between the stator magnetic poles 6a and 6b, and 7a and 7b.
2 and the auxiliary rotor 13 are statically and stably stationary at an angle offset from the dynamic magnetic center, thereby determining the self-startability and rotational direction of the rotors 8, 9.
That is, each time an inverted pulse signal is supplied to the coil 4, the rotors 8 and 9 each rotate step by step by 180 degrees. Note that 14 is a long hole formed in the plate 3.

うになつている。 The rotors 12 and 13 each have a pinion (not shown) at their lower portions, which mesh with a gear 15 of a clock train and a gear 16 with a battery life indicator. One side (for example, the top side) of the battery life indicator gear 16 is color-coded into red and white, and a clock dial or a watch case (not shown) is provided.
The gear 16 can be seen through the window hole 17 made in the figure.

換する。 Most of the magnetic flux from the coil 4 passes through the main magnetic flux path 18 shown by the solid line, and the rest passes through the sub magnetic flux path 19 shown by the broken line. While the battery voltage is sufficient, sufficient magnetic flux passes through the sub-magnetic flux path 19 to drive the rotor 13, so that the rotors 12 and 13 operate together. For this purpose, the clock is driven through the gear 15, and since the gear 16 is driven, two colors can be seen alternately in the form of seconds flashing through the window hole 17, and therefore it is possible to know that the clock is operating. can. As time passes and the battery voltage drops to near the end of its life, rotor 12 is still operating, but rotor 13 no longer operates. Therefore, although the clock is still running, the second flash will no longer be displayed in the window hole 17, allowing the user to know that the battery is nearing the end of its lifespan, and should therefore replace it with a new battery.

できる。その他に安価に構成できる。 As described above, the present invention forms stator magnetic poles 6a and 6b for the main rotor 12 that drives the clock train 15 on the main magnetic flux path 18, and stator magnetic poles for the auxiliary rotor 13 that drives the gear with battery life display. 7a, 7b
The minimum starting voltage of the auxiliary rotor 13 is only made higher than that of the main rotor 12 by forming the auxiliary magnetic flux path 19 on the auxiliary magnetic flux path 19 which is separate from the main magnetic flux path 18. Therefore, it is not necessary to provide a complicated circuit. It is possible to display an advance notice of the battery life without any warning, and in addition to this, it is possible to display an operation display usually using a seconds flash. In addition, it can be constructed at low cost.
