    摘要： To provide an electronic timepiece enabling reliable detection of a state of rotation of an indication wheel such as a date dial.
    An ultrasonic motor 1130 has an ultrasonic rotor pinion 1134b. A date dial 1120 is disposed on a main plate 1102 in such a way as to rotate relative thereto. The ultrasonic rotor pinion 1134b is meshed with an intermediate date driving gear wheel 1142a. A date driving wheel 1150 is rotatably disposed on the main plate 1102. A date driving gear wheel 1150b is meshed with an intermediate date driving pinion 1142b. A date driving gear portion 1150b is meshed with a dial gear portion 1120a. A contact point spring 1160 is disposed on a spring guiding portion 1150d. The contact point spring 1160 rotates integrally with the date driving wheel 1150 through the rotation of the date driving wheel 1150. The state of rotation of the date driving wheel 1150 can be detected by contact of the contact point spring 1160 with the contact point pattern 1174.

    摘要： An ultrasonic motor has an ultrasonic rotor 102 having an ultrasonic rotor kana 102b in mesh with an intermediate gear 104a of an intermediate date driving wheel 104. The intermediate date driving wheel 104 has an intermediate date driving kana 104b in mesh with a date driving gear 106a of a date driving wheel 106. A date finger 108 is provided on the date driving wheel 106 and simultaneously rotated by rotation of the date driving wheel 106. A date dial 110 is rotatably assembled on a main plate 112. A date jumper 116 has a rectifying portion 116a to rectify a date dial tooth 110a. The date jumper 116 has a date jumper spring portion 116b.
