摘要:
In detecting power generation of an electronic timepiece having a conventional power generating unit, voltage output by the power generating unit is limited by output from a storage unit since the power generating unit and the storage means are connected when the power generation state is detected, and voltage equal to or larger than voltage output from the storage unit cannot be detected. An electronic timepiece is provided which can overcome the problem and can check an operation of the power generating unit securely irrespective of the state of the storage means.In an electronic timepiece driven by power stored from a power generating unit (1) into a storage unit (4), the electronic timepiece includes a power generation detecting unit (2) that detects a power generation state of the power generating unit (1) and a switch unit (7) that separates the power generating unit (1) and the storage unit (4) when the power generation state of the power generating unit (1) is detected. In this case, the switch (7) between the power generating unit (1) and the storage unit (4) is controlled to OFF so that the output from the power generating unit (1) cannot be limited by the output from the storage unit (4).

When a stem switch (8) is pulled out, a switch signal forming unit 9 outputs a signal (RS) indicating that effect, a control unit (13) receives the signal (RS) and starts clocking by a timer (13a). The control unit (13) receives a signal (HS) output from an electricity-generation detecting unit (12) within the clocking period, detects the electricity generating operation of an electricity generating unit (10), and outputs a signal (CS) indicating that effect. A narrow pulse forming unit (7) forms a narrow pulse having a width of such a degree that the motor (5) is not driven based on the signal (CS), and outputs the narrow pulse to a motor driving circuit (4). The motor driving circuit (4) flows a fine current through a coil (4a) which drives the motor (5) based on the narrow pulse. An external device detects a variation of the narrow pulse, thereby confirming whether electricity is generated.

摘要:
Impact detecting resistors (141), (143) of an impact detecting circuit (104) detect a counter electromotive force of a step motor (105) generated due to an impact. This counter electromotive force is amplified applying a predetermined period and a predetermined chopper-width by a chopper-amplifying waveform shaping circuit (118). Therefore, even a light impact can be detected. Inverters (145), (146) compare these impact detecting signals (S22), (S23) with a threshold value and detect an impact when the signals exceeds the threshold value. A controlling circuit (102) provides a lock pulse to the step motor (105) through signal lines (AA), (BB) when an impact is detected, brakes rotation of a rotor (162) thereby preventing a deviation of the time displayed with a second hand (106).
