The setting lever engagement pin 118b of the setting lever 118 is located in the setting engagement window portion 170a of the setting lever 170. Therefore, the 11
The rotation of 8 allows the setting lever 170 to rotate. The setting lever 170 is formed of a metal elastic material, and is electrically connected to the positive side of the battery. Therefore, when the setting lever 170 comes into contact with the pattern of the circuit block, the input terminal of the integrated circuit connected to the pattern is set to “HIGH”. Next, the operation of the timepiece with a winding true position detecting device of the present invention will be described.

Referring to FIG. 2, when the winding stem 130 is at the 0th stage, the setting lever 170 is at a position rotated counterclockwise, and the pattern contact portion 170c is in contact with the first pattern 120a of the circuit board 120. Contact. In this state, the input signal determination circuit built in the integrated circuit does not output an output signal. The setting portion 17 of the setting lever 170

The ratchet wheel 150 is positioned at an intermediate position in the axial direction, and the ratchet wheel 150 does not mesh with the small wheel wheel 152. Referring to FIG. 3, when the winding stem 130 is pulled out from the 0th stage to the first stage, in a state where the winding stem 130 is at the first stage, the train wheel setting lever 170 is at an intermediate position rotated clockwise, and The contact portion 170c does not contact either the first pattern 120a or the second pattern 120b of the circuit board 120. In this state, the input signal determination circuit built in the integrated circuit outputs a first output signal. The train wheel setting portion 170b of the train wheel setting lever 170 is separated from the outer peripheral portion of the gear wheel of the fourth wheel & pinion 160.

The wheel wheel 150 is positioned at a position closer to the outer periphery of the movement in the axial direction, and the wheel wheel 150 does not mesh with the small iron wheel 152. Therefore, by rotating the winding stem 130 in this state, the continuous wheel 15

Engage with 52. Therefore, by rotating the winding stem 130 in this state, the minute wheel and the hour wheel rotate via the rotation of the continuous wheel 150 and the small iron wheel 152, and the time of the clock can be adjusted. The rotation direction of the train wheel setting lever 170 when the winding stem 130 is pulled out from the 0th stage to the first stage is equal to the rotation direction of the train wheel setting lever 170 when the winding stem 130 is pulled out from the first stage to the second stage. Therefore, the shape of the butt-fitting window portion 170a of the setting lever 170 can be made small and simple. As a result, the setting lever 170 can be reduced in size, and the size of the timepiece can be reduced. Referring to FIG. 5, a setting lever screw pin 180 is fixed to main plate 102. The setting lever 170 is rotatably incorporated with respect to the setting lever screw pin 180. The train wheel receiving 182 is
By 4, it is fixed to the setting lever screw pin 180. The setting lever 170 is arranged so as to be rotatable between the main plate 102 and the train wheel bridge 182.

When the winding stem 130 is at the 0th stage, the pattern contact portion 170c of the train wheel setting lever 170 is

Twenty first patterns 120a and second patterns 120b
(Indicated by a two-dot chain line in FIG. 5). When the winding stem 130 is in the second stage, the pattern contact portion 170c of the setting lever 170 is in contact with the second pattern 120b of the circuit board 120 (shown by a broken line in FIG. 5). Referring to FIG. 6, when the pattern contact portion 170c of the setting lever 170 is not in contact with either the first pattern 120a or the second pattern 120b, the input signal determination circuit 210 built in the integrated circuit 140

Table 2 shows the signal output in such a timepiece with a winding true position detecting device according to the present invention.

[0028]

[Table 2] Output of signal in timepiece with winding true position detecting device of the present invention位置 Position of winding true 1st pattern 2nd pattern Output signal ０ 0 stage Eye ON OFF No 1st stage OFF OFF Output 1st output signal 2nd stage OFF ON Output 2nd output signal ───────────────────── Therefore, in the timepiece with a winding true position detecting device of the present invention, the input from the first pattern 120a and the input from the second pattern 120b are performed by the operation of the input signal discriminating circuit. Are both "LOW", the first output terminal is "HIGH", and only the input from the second pattern 120b is "HIGH".
When "H", the second output terminal is set to "HIGH".

Referring to FIG. 7, in input signal discriminating circuit 210 used in a timepiece with a winding true position detecting device according to the present invention, a signal from first input terminal P1 is supplied to first inverter 22.
It is inverted by 0 and input to the first AND circuit 226. The signal from the second input terminal P2 is inverted by the second inverter 222 and input to the first AND circuit 226. 1st AN
The output signal of the D circuit 226 is output to the first output terminal F1. The signal from the first input terminal P1 is inverted by the third inverter 224 and input to the second AND circuit 228. The signal from the second input terminal P2 is supplied to the second AND circuit 22
8 is input. The output signal of the second AND circuit 228 is output to a second output terminal F2. Referring again to FIG.
The signal from the first pattern 120a is input to the first input terminal P1. The signal from the second pattern 120b is input to the second input terminal P2.

When the winding stem 130 is in the first stage, the first
The output signal from the output terminal F1 is sent to the date feed motor drive circuit 25.
Output to 0. When the first output terminal F1 is “HIGH”, the date feed motor drive circuit 250 is set in an operable state, and the date correction device is operated by rotating the winding stem 130 to operate the date feed motor 252. The date wheel 254 is rotated based on the operation of the date motor 252, and the date wheel 254 can rotate the date wheel 256. For example, the date correction device includes a correction wheel that rotates through rotation of the pinwheel 150 due to rotation of the winding stem 130, a correction switch lever that operates based on the rotation of the correction wheel, and a correction switch that contacts the correction switch lever. A pattern and a correction signal output when the correction switch lever comes into contact with the correction pattern are input, and the date feed motor drive circuit 250 is input.
And a correction driving circuit for driving the driving circuit.

When the winding stem 130 is in the second stage, the second
A reset control signal is output from the output terminal F2 to the reset control circuit 240. The second output terminal F2 is "HIGH"
, The reset control circuit 240 outputs a reset signal to the front wheel train motor drive circuit 242. Then
The front train wheel motor drive circuit 242 is reset, and the output of the drive signal for driving the front train wheel motor 244 is interrupted.
Therefore, in this state, the front train wheel 246 does not rotate. When the winding stem 130 is moved from the second stage to the first stage (or from the first stage to the zeroth stage), the output of the reset release control signal from the second output terminal F2 to the reset control circuit 240 is changed. Disappears. That is, the second output terminal F2 is “LOW”
, The reset control circuit 240 outputs a reset release signal to the front wheel train motor drive circuit 242. When one second has elapsed, the front train wheel motor drive circuit 242 starts operating and outputs a drive signal for driving the front train wheel motor 244. Therefore, in this state, the front train wheel 246 can rotate.

When the winding stem 130 is moved from the second stage to the first stage (or from the first stage to the zeroth stage), the train wheel setting portion 170 b of the train wheel setting lever 170 moves the gear wheel of the fourth wheel & pinion 160. Move away from the outer part. Therefore, by moving the winding stem 130 from the second step to the first step (or from the first step to the 0th step), the fourth wheel 16 by the train wheel setting lever 170 is moved.
The zero rotation state is released.

According to the present invention, as described above, the timepiece with the winding true position detecting device is configured as described above, and has the following effects. (1) The timepiece with the winding stem position detecting device of the present invention sets the winding stem to 0
Since the rotation direction of the train wheel setting lever when moving the winding stem from the first step to the first step is the same as the rotation direction of the train wheel setting lever when moving the winding stem from the first step to the second step, the train wheel setting lever can be downsized. Thus, the shape can be simplified. (2) Since the space required for disposing the setting lever is small, a small timepiece with a winding true position detecting device can be realized. The structure of the present invention is particularly advantageous when manufacturing a small wristwatch for women.
