[0112] Next, a first embodiment of the position detector, including the position detector 610 and the circuit block 606 in the embodiment of the position detector mechanical watch of the present invention will be described.

[0113] As shown in FIGS. 1 to 4 , the position detector 610 and the circuit block 606 are arranged on the front side of the main plate 102 . The position detector 610 is fixed on the circuit block 606 . Circuit block 606 includes a plurality of terminals.

[0114] A first lead 182 is provided to connect one terminal of the coil 180 to a first terminal (not shown) of the circuit block 606 . The other terminal of the coil 180 is connected to one terminal of the coil 180a. The other terminal of the coil 180a is connected to one terminal of the coil 180b. The other terminal of the coil 180b is connected to one terminal of the coil 180c. That is, four coils 180, 180a, 180b, 180c are connected in series.

[0115] A second lead 184 is provided to connect on...

[0216] Next, a second embodiment of the position detector of the present invention will be described, including the position detector 620 in the embodiment of the position detector mechanical watch of the present invention.

[0217] In the following description, differences between the second embodiment of the position detector of the present invention and the first embodiment of the position detector of the present invention will be mainly described. Therefore, in addition to the following description, part of the above description of the first embodiment of the position detector of the present invention will also be used.

[0218] As shown in FIG. 16, the position detector 620 has a housing 620a whose shape is substantially circular when viewed from the top, and whose shape is substantially "oval" when viewed from the side, that is, the longitudinal section of the central portion.

[0219] "Oval" as defined herein includes geometrically ovoid shapes and shapes close to ovoid...

[0296] Next, a third embodiment of the position detector of the present invention will be described, including the position detector 630 in the embodiment of the position detector mechanical watch of the present invention.

[0297] In the following description, differences between the third embodiment of the position detector of the present invention and the first embodiment of the position detector of the present invention will be mainly described. Therefore, in addition to the following description, part of the above description of the first embodiment of the position detector of the present invention will also be used.

[0298] As shown in FIG. 18, the position detector 630 has a housing 630a whose shape is substantially circular when viewed from the top, and whose shape is substantially circular when viewed from the side, that is, the longitudinal section of the central portion. Thus, housing 630a is substantially spherical.

[0299] In FIG. 18, let the x-axis (the right ...

Abstract

The invention provides a mechanical timepiece provided with an attitude detector. The operation of a balance (140) is controlled according to the attitude of the mechanical timepiece detected by the attitude detector (610). The attitude detector includes a case (61Oa) having a circular top view and an oval side view, a plurality of patterns (A1 - E2) arranged inside the case (610a), and conductive fluid (608) held in the case (610a).

Description

technical field [0001] The present invention relates to a mechanical watch including a position detector, and controls the rotation of a balance wheel on the basis of the result of the position of the mechanical watch detected by the position detector. Background technique [0002] (1) The structure of prior art mechanical watch: [0003] As shown in FIGS. 31 and 32, a movement (body) 1100 of a prior art mechanical watch has a main plate 1102 forming a base plate of the movement. The winding stem 1110 is rotatably fitted in the winding stem guide hole 1102 a of the main plate 1102 . A dial 1104 (shown in dashed lines in FIG. 32 ) is mounted on the movement 1100 . [0004] Assuming that the dial is in the installed state, in the mechanical watch, the case where the dial becomes horizontal is defined as "flat position" and the case where the dial becomes vertical is defined as "upright (vertical) position". [0005] In addition, assuming that in the state where the dial is ...
