摘要： In an electronic unit having a plurality of motors, a reduction in power-supply voltage is suppressed even if the plurality of motors are driven, and a difference in hand moving timing is allowed to be made inconspicuous.
An electronic timepiece having a seconds motor for driving a seconds hand and an hour-and-minute motor for driving hour and minute hands, which serves as an electronic unit, moves the seconds hand and the hour and minute hands such that, when a seconds auxiliary pulse signal is output to the seconds motor at the hand moving timing of the seconds hand, control is applied in a way in which neither magnetic-field detection around the hour-and-minute motor nor the rotation detection of the hour-and-minute motor is performed at the hand moving timing of the hour and minute hands, and an hour-and-minute auxiliary pulse signal is output to the hour-and-minute motor.摘要翻译： 在具有多个电动机的电子单元中，即使驱动多个电动机，也能够抑制电源电压的降低，并且允许不正确的手动定时的差异。 具有用于驱动秒针的秒针马达和用于驱动小时针的小时和分针的电子钟表用作电子单元，使秒针和小时针和分针移动，使得当秒 辅助脉冲信号在秒针的手移动定时被输出到秒马达，以小时和分钟马达周围的磁场检测都不进行控制，也不进行小时和小时的旋转检测， 小时和分针的手移动时刻执行分钟马达，并且将时分辅助脉冲信号输出到小时和分钟马达。

摘要： An electronic device having a plurality of motors do not cause drop of the power supply voltage and large difference in hand driving timings even when the motors are operated. When the electronic device is an electronic watch having a second motor for driving a second hand and an hour/minute hand motor for driving an hour/minute hand, and when a second auxiliary pulse signal is outputted to the second motor at the driving timing of the second hand, detection of the magnetic field around the hour/minute motor and detection of the rotation of the hour/minute motor are not performed at and after the driving timing of the hour/minute hand. An hour/minute auxiliary pulse signal is outputted to the hour/minute motor to drive the second hand and the hour/minute hand.
