摘要： Provided is an electronic watch which achieves a highest-speed fast-forward operation of a step motor based on various environments under which the watch is placed, and enables low-power driving. The electronic watch includes: a normal pulse generator circuit (5) configured to output a normal pulse SP for driving a step motor (30); a detection pulse generator circuit (10) configured to output, after the step motor (30) has been driven with the normal pulse SP, detection pulses DP1 and DP2 for detecting whether or not the step motor (30) has been rotated; a pulse selection circuit (7) configured to selectively output the normal pulse SP and the detection pulses DP1 and DP2; a rotation detector circuit (40) configured to input detection signals DS1 and DS2 generated from the detection pulses DP1 and DP2, and to determine whether or not the step motor (30) has been rotated; and a frequency selection circuit (4) configured to determine a driving interval of the normal pulse SP, in which the rotation detector circuit (40) is configured to instruct the frequency selection circuit (4) to select a frequency corresponding to a position at which the detection signals DS1 and DS2 have been generated.

摘要： Anelectronicwatch (1) includes: a step motor (30) ; a driving pulse generator circuit (5) configured to output a driving pulse (SP) for driving the step motor; a detection pulse generator circuit (10) configured to output a detection pulse for detecting rotation of the step motor; a correction pulse generator circuit (6) configured to output a correction pulse (FP) ; a pulse selection circuit (7) configured to select and output the driving pulse, the detection pulse, and the correction pulse (FP); a driver circuit (20) configured to supply to the step motor the outputs from the pulse selection circuit (7); and a rotation detection circuit (40) configured to receive a detection signal generated by the detection pulse (CP) to judge rotation of the step motor. The electronic watch (1) further includes a driving interval switch circuit (4) configured to switch a driving interval of the driving pulse (SP) between a normal driving interval and a high-speed driving interval. The rotation detection circuit (40) is capable of changing a detection condition by the driving interval switch circuit (4).
