[Table 1] Signal output in the watch with the setting lever of the present invention True position 1st pattern 2nd pattern Output signal ────────────────────────────────── 0th stage ON OFF None First stage OFF OFF Output first output signal Second stage OFF ON Output second output signal ──────────────────────── Therefore, in the timepiece with a train wheel setting lever according to the present invention, both the input from the first pattern 120a and the input from the second pattern 120b are set to “LO” by the operation of the input signal determination circuit.
When "W", the first output terminal becomes "HIGH", and when only the input from the second pattern 120b becomes "HIGH", the second output terminal becomes "HIGH".

Referring to FIG. 7, in the input signal discriminating circuit 210 used in the timepiece with the train wheel setting lever of the present invention, the first
The signal from the input terminal P1 is inverted by the first inverter 220 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. First AND circuit 2

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.

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.
