Abstract

PURPOSE:To reduce the loss depending upon the life of a battery and allow a user to charge the battery through easy operation without any restriction of the outward shape of a dial, etc., by performing the charging through the electromagnetic coupling between a charger and a coil. CONSTITUTION:The charger and coil in the timepiece are coupled together electromagnetically and electromagnetically induced power is charged in a secondary battery or capacitor through a charging circuit. Then, a magnetic field from the charger operates on both the coil of the charging circuit and the coil of a stepping motor which drives an analog quartz watch once a second during the charging operation. For the purpose, an external operation member (e.g. crown) is operated during the charging operation to control the rotor of the stepping motor forcibly, preventing the rotor from rotating erroneously. Further, when the external operation member is operated, a control circuit operates to receive the signal of a braking circuit and then turn off a driving circuit. Further, a counting and coincidence circuit counts the charging time and performs corrective driving operation for the charging time after the charging is reset. When the external operation member is returned to its original position after the charging, the charging circuit turns off and the driving circuit turns on.

A second-order battery or an Ll-order' battery is used. For this reason,
As batteries reach the end of their service life, they have to be disposed of and replaced, causing economic loss and secondary inconvenience to users. Furthermore, there were also problems of environmental pollution and loss of resources related to disposal. Therefore, we attached a solar battery to part of the letter plate of an analog quartz watch, and used silver oxide 2 to transfer the energy from the solar battery.
A method of extending the battery life of a watch by recharging the battery has been published. However, when placing a solar cell on the dial of a wristwatch, there are design constraints such as
It was impossible to use it extensively in analog quartz watches, which sell decorative beauty.

The signal from the lul path is frequency-divided, a waveform synthesis circuit synthesizes the pulses necessary for driving the motor, and sends the synthesized pulses to the drive circuit. The motor drive circuit outputs the power necessary to fully drive the motor and sends it to the motor. The motor is normally driven with short pulses once per second. The rotational force of the motor is transmitted to the wheel train, rotates the 111 wheel train, and drives the hour, minute, and second hand indicating mechanism on the dial.

At this time, the rotor of the stepping motor rotates as a result of the magnetic field. If you don't mind, this will be a big disadvantage when considering this stem. Therefore, when the light is on, by fully operating the external operating member (in other words, the crown), the rotor of the stepping motor is forcibly adjusted to prevent incorrect rotation of the rotor.
