Description of the Related Art In recent years, a variety of electronic watches have begun to appear in response to various market needs, and there has been a strong demand for diversification of watches, not only digital watches, but also hand-held timepieces. Needle-display type calendars and moon age displays are available on the market. Furthermore, as an electronic timepiece with a novel design, an electronic timepiece that displays by rotating the stepping motor forward and reverse and driving the day hand in a sector shape has also appeared.

る。In the case of an electronic timepiece, a special pulse is applied to drive the stepping motor in a reverse rotation. That is, in order to rotate one pulse in reverse, a pulse for normal rotation is applied first, the rotor is swung to the normal rotation side, and then a pulse for reverse rotation is applied. In addition, a stopper is always provided in the middle of the rotating member when the fan-shaped display is to be performed by using the forward and reverse rotation of the step motor. Therefore, when the day of the week is to be corrected, it is essential that the drive be performed reliably even when the stopper is hit. However, when the rotor is stopped by hitting the stopper, the stopper may prevent the rotor from rotating in the normal rotation direction depending on the stop position of the rotor, and may fall into a state in which the rotor cannot be reversely rotated.

A rotation member is provided in one of the reduction gear trains from the rotor of the step motor to the pointer wheel of the fan-shaped display unit to change the rotation of the step motor from normal rotation to reverse rotation with a correction member that works with the external operation member The rotating member is pushed in the direction of rotation to escape from the state in which reverse rotation is impossible and can be rotated.

な複雑な構造となる。However, according to the conventional example described above, in order to make the step motor escape from the state in which reverse rotation is impossible, the correcting member must be moved in the direction in which the step motor reversely rotates. That is, since the correcting member must be moved to the side where the rotating member is operating normally, there is a possibility that the correcting member enters the normal operating range of the rotating member. Therefore, there is a possibility that the hands may be moved when the external operation member is pressed even when the hands are operating normally. In particular, in an electronic timepiece in which two hands are coaxially provided and displayed in a fan shape, a method of rotating with a correction member has a complicated structure such that two correction members are required.

Reference numeral 14 denotes a month step motor for driving the month hand 5 in a fan display by electric control from the IC 34, reference numeral 15 denotes a month rotor constituting the month step motor 14 together with the month coil 16 and the month yoke 17, and the month rotor 1
Reference numeral 5 is supported by precious stones fixed to a base plate 18 serving as a clock base and a train wheel bridge 19. A moon yoke 17 and a moon coil 16 are stacked on the upper surface of the main plate 18.
The driving force of the month wheel 20 to which the month hand 5 is attached is transmitted from the moon rotor 15 via the middle month wheels (1) 21 and (2) 22, which are reduction gear trains. The lunar middle wheel (1) 21 is pivotally supported by precious stones fixed to the back plate 37 and the train wheel bridge 19, and the lunar middle wheel (2) 22 is, like the moon rotor 15, the main plate 18 and the wheel train bridge. It is supported by precious stones fixed to 19. The month wheel 20 comprises a month wheel stem 20a to which the month hand 5 is attached and a month gear 20b made of a synthetic resin which receives a rotational force.
The rotation restricting convex portion 20c which overlaps with the cross section a and serves as a stopper when restricting the rotation of the month wheel 20 is integrally formed.

板３９の下面に実装されたＩＣ３４が配置されている。The rotation restricting member 30 is disposed on the upper surface of the base plate 18 at a position not overlapping the wheel train in a plane. The rotation restriction on the forward rotation side of the step motor is performed by applying the rotation restricting projections 20c and 27c of the month gear 20b and the date gear 27b to the rotation restricting portion 30a of the rotation restricting member 30. At this time, the planar position regulation of the rotation regulating member 30 is as follows.
It is performed by the reaction force of the support 36 implanted on the main plate 18 and the spring portion 30c of the rotation restricting member 30. The forward rotation of the step motor in the present embodiment means that the month rotor 15 and the day rotor 24 rotate counterclockwise. On the other hand, the rotation of the stepping motor on the reverse rotation side is controlled by the moon gear 20b.
In addition, the rotation regulating projections 20c and 27c of the date gear 27b are applied to the end 18b of the elongated hole 18a of the base plate. Therefore, the month hand 5 and the day hand 6 do not hit the antenna 7 even if the IC 34 runs away. Further, the cross-sectional relationship between the IC 34 and the rotation restricting member 30 is a synthetic resin in which the rotation restricting member 30 is disposed on the upper surface of the main plate 18 and a gap necessary for sliding the rotation restricting member 30 is provided thereon. The resulting circuit support base 38 is arranged, and further above it, the IC 34 mounted on the lower surface of the circuit board 39 is arranged.

(PB3) 11, (PB4) 12, and (PB5) 13 are simultaneously pressed. With this operation, the month rotor 15 and the day rotor 24 are rotated in reverse by an electric signal from the IC 34 and driven to the initial position. Also, (PB

る。By pulling (PB1) 9 in the series of operations, the winding stem 31 integrated with (PB1) 9 is pulled, and the mandrel 33 is pivoted on the support 32 implanted on the main plate 18 as a rotation axis. Rotates, and the end 33a of the mandrel 33 rotates counterclockwise to push the end 30b of the rotation restricting member 30.
Then, the rotation restricting portion 30a of the rotation restricting member 30 having the support shaft 35 implanted on the base plate 18 as a rotation axis rotates counterclockwise, and the rotation restricting portion 30a is shifted leftward from the illustrated position.
By shifting to the left, each step motor 1 on the month and day
Since the restriction is released from the restriction of the rotors 4 and 23, the rotor can be rotated in the normal rotation direction to such an extent that the rotor is not sucked to the next stable point required for the reverse rotation, and can be rotated in the reverse direction.
