る。 FIG. 9 is an exploded perspective view of the main parts. 16 is a movement front case, 17 is a movement rear case, 18 is a motor core, 19 is a coil, 20 is a rotor, 21 is a second wheel, and 22 is a minute wheel. The movement front case 16 has a rotor 20 and a second wheel 21.
The portion other than the portion that holds the minute wheel 22 is largely hollowed out. Therefore, there is a gear 2 inside the movement front case 16 and the movement rear case 17.
1, 22, the iron core 18, and the coil 19 to form the mechanical part A are attached to the dial plate 8, so that the circuit components of the dial plate 8 are housed in the mechanical part A.

方向に回転する。 The connection between the coil 19 and the output terminal of the integrated circuit 10 can be made by leaving some slack in the wire and attaching the mechanical part A to the dial plate 8 after soldering, or by using a terminal board. When attached to the dial plate 8, it may be made to come into contact with the pattern of the dial plate 8. The output of the integrated circuit 10 is such that an output having a constant pulse width is generated every 30 seconds, for example, so that current alternately flows through the coil 19. One end of the iron core 18 is bent inward in a V-shape, and a rotor 20 is disposed between it and the other end.
The rotor 20 is magnetized into two poles. Gaps a, b, c at each part between the rotor 20 and the iron core 18
is such that a<b<c. Therefore, when current flows through the coil 19, the rotor 20 rotates in one direction.

裕を加えた値で良い。 FIG. 11 is an enlarged view of the central portion, and FIG. 12 is a perspective view of the hour and minute hands. 30 is a minute hand shaft, which is fixed to the minute wheel 22. 31 is a minute hand bushing, which is press-fitted and fixed to the minute hand shaft 30. The minute hand bush 31 includes an eccentric cam 31a, a protrusion 31b and a flange 3.
1c, and the protrusion 31b is the notch 2 of the minute hand 27.
7a. The eccentric cam 31a engages with the center hole 28a of the hour hand 28. The hour hand 28 is provided with an internal gear 28b having 12 teeth, and the movement front case 16 is formed with a fixed gear 16b having 11 teeth concentrically with the minute hand shaft hole 16a. Fixed gear 16
The internal gear 28b meshes with the internal gear 28b, and the eccentric cam 31a rotates, whereby the hour hand 28 rotates 1/12 for one rotation of the minute hand bushing 31. The minute hand 27 is attached with some play between the minute hand bush 31 and the hour hand 28. For the direction of rotation, the protrusion 31b
and notch 27a, and can move to some extent in the front and rear directions. The gap between the front cover 24 and the dial 8 may be a value equal to the thickness of the hour hand 28 and minute hand 27 plus the thickness of the flange 31c plus some allowance.

できる。 With this configuration, the following advantages can be obtained. Since the solar cells 13 are not directly visible but only visible through the flange 24a of the front cover 24, the appearance is excellent. The surface of the aluminum-based printed board is used as the dial 8, and the solar cell 13, circuit block, etc. are mounted on the back surface, and the mechanical part A and the circuit block are mounted so that they do not overlap, resulting in a thin watch. can. Since dial 8 is a printed board, solar cell 1
There is no need for special parts to attach 3, and the number of assembly steps can be reduced. The circuit block and mechanical part A can be separated, making assembly and disassembly easy. The solar cells 13 can be arranged so as to be visible over the entire outer periphery of the front cover 24. Therefore, it is not necessary to prevent the hour and minute hands 27 and 28 from being exposed to light, and the minute hand 27 can be extended to the edge of the case. The degree of freedom in exterior design increases, and this also makes it possible to create products with excellent aesthetics. Since the dial 8 is an aluminum-based printed board, unlike those made of Bakelite or the like, the surface of the base material 8a is clean and can be used as is by simply displaying the time without painting.

ある。 FIG. 13 shows another embodiment. In this example, the outer peripheral portion of the dial 8' is bent and the solar cell 13 is attached to the bent portion. Therefore, the solar cell 13 is perpendicular to the main surface of the dial 8'. The transparent ring 25' has two inclined surfaces 25a',
25b'. The rest is the same as the first embodiment.
