摘要： A piezoelectric drive device (10) includes a piezoelectric actuator (20) including a vibrator (21) having piezoelectric elements, and a rotor (30) that is rotated in one specific direction by the vibrator (21); and a rotation transfer device (40) that transmits rotational energy from the rotor (30) to a driven rotating body, includes an elastic device (42) that can store rotational energy transmitted from the rotor (30) as elastic energy, and a rotation limiting device (43) that has a drive wheel (431) and a driven wheel (435) that rotates in conjunction with rotation of the drive wheel (431), allows the driven wheel (435) to rotate a specific angle in conjunction with rotation of the drive wheel (431), and restricts driving the drive wheel (431) from the driven wheel (435) when the driven wheel (435) rotates this specific angle. The elastic device (42) and the rotation limiting device (43) are disposed so that rotational energy transmitted from the rotor is transmitted through one to the other of the elastic device (42) and the rotation limiting device (43); and the rotor (30), the elastic device (42), and the rotation limiting device (43) render a serial path for transmitting rotational energy.

摘要： To provide a portable electronic device which is easily shifted into a power save mode at the discretion of an operator, such as a user and reduces power consumption at an optimum state in accordance with the state of use by each operator.An operator, such as a user, can force an electronic device into a power save mode at the operator's own discretion by manipulating a control. Electrical energy stored is thus reliably saved in accordance with the usage by the operator, and power consumed in vain is more efficiently reduced than in a method in which a device automatically stops a time displaying and is shifted into a power save mode in accordance with the presence or absence of power generation. With the time limit within which the operational state of the control needs to be complete, the operator is free from an erroneous shift into the power save mode, and the ease of use of the time measurement device is still assured.

There is provided an electronic watch having a base on which are mounted a dynamo including a dynamo wheel train for transmitting external force to a dynamo rotor, a secondary power supply for storing electric energy generated by said dynamo, a circuit section including a driving circuit supplied with power from said secondary power supply, a stepping motor driven by said driving circuit, and a watch wheel train for transmitting torque from said stepping motor to a time indicting member, wherein:

at least one of a rotational shaft of said dynamo rotor and a rotational shaft of said dynamo wheel train is supported at an axial end thereof by a ball bearing of which balls abut against said rotational shaft in the radial direction to restrict a lateral inclination of said rotational shaft, and
the balls of said ball bearing are held in abutment against a stepped portion formed at the axial end of said rotational shaft, thereby restricting the position of said rotational shaft in the axial direction.
