Timepiece device mechanism for indicating restart after recharging |
摘要 |
A timepiece device mechanism for indicating the restart of pointer movements after recharging following a halt condition. The timepiece device includes a display for displaying time information wherein the display is driven by a display-drive. A termination-detector monitors the operation of the display and outputs a termination detection signal when detecting a halt of the display. A storage unit receives and holds the termination detection signal and outputs a termination-storage signal in response thereto. A power supply outputs a voltage and a power-supply-voltage detector detects the voltage-level output of the power supply and outputs a power-supply-voltage detection signal when the voltage is greater than or equal to a first reference voltage that is higher than a movement-start voltage. A modulation signal generator receives the termination storage signal and power-supply-voltage detection signal and outputs a modulation signal when the power-supply-voltage detection signal is output while the termination-storage signal is being input to the modulation-signal generator. The display-drive receives the modulation signal and performs modulated driving of the display in response thereto.
