摘要： In an electronic apparatus including a generator device for generating power, a storage device for storing the generated electric energy, and a motor driven by the electric energy stored in the storage device, it is detected whether a magnetic field is generated by power generation. If it is detected that a magnetic field is generated by power generation, a correcting driving-pulse signal having an effective power larger than a normal driving-pulse signal, which is output for controlling the driving of the motor, is output to the motor. In performing this operation, a determination is made by assuming that a magnetic field is generated while the storage device is in the charging state.

摘要： A pulse motor driving device having a rotation detecting unit adapted to detect whether or not a pulse motor rotates. In this device, a control unit performs an operation of increasing the effective value of the driving power of the pulse motor and periodically performs an operation of lowering the effective value of the driving power thereof when it is detected by the rotation detecting unit that the pulse motor does not rotate. Further, the control unit interrupts the operation of lowering the effective value of the driving power of the pulse motor when a magnetic field is detected by a magnetic detecting unit.

摘要： In an electronic apparatus which includes a power generator and a storage device for storing electric energy obtained thereby, it is detected whether a motor driven by the stored electric energy is rotating by comparing the rotation detecting voltage, which is proportional to the induction voltage generated in the motor caused by the rotation of the motor, with a rotation reference voltage. The generation state of the power generator or the charging state of the storage device is detected. The level of the rotation detecting voltage or the level of the rotation reference voltage is shifted by a predetermined amount based on the detected generation state of the power generator or the detected charging state of the storage device so that the voltage difference between the rotation detecting voltage and the rotation reference voltage is increased during the no-rotation period.
