The first gear 210 is provided with a lever fitting portion 420 formed of a first boss 421 and a rib 422. The lever 410 is provided with a recess 412 into which the first boss 421 is fitted and a second boss 413 that comes into contact with the rib 422.

  The illustrated lever operation means 430 is a guide groove provided in the substrate body 500. The lever 410 is provided with an operated boss 414 that is locked to the lever operating means 430. In addition, a long hole 231 that penetrates the boss 414 to be operated is provided at a point of the third gear 230.

  The locking of the third gear 230 by the locking means 400 depends on the phase relationship between the first gear 210 and the third gear 230. The operation of the locking means 400 is as follows.

  First, in a state where the lever 410 and the lever fitting portion 420 are separated from each other, only the first gear 210 rotates (see FIG. 4). When the first gear 210 rotates and the lever fitting portion 420 approaches the lever 410 (see FIG. 5), the first boss 421 is fitted into the recess 412 and the lever 410 is pushed by the first boss 421. It becomes a state.

  When the first gear 210 further rotates, the lever 410 is pushed by the first boss 421, whereby the third gear 230 rotates, and the operated boss 414 moves in the guide groove serving as the lever operating means 430, while the lever 410 moves first. The three gears 230 rotate. The amount of rotation of the lever 410 with respect to the third gear 230 is regulated by the lever operating means 430. When the lever 410 rotates in this way, the second boss 413 comes into contact with the important part of the rib 422, the lever 410 is sandwiched between the first boss 421 and the rib 422, and the lever 410 and the lever fitting portion 420 are fitted. Then, the third gear 230 is engaged with the first gear 210 (see FIG. 6).

  When the first gear 210 further rotates, the third gear 230 rotates in synchronization with the first gear 210 (see FIG. 7). Here, the range of movement of the operated boss 414 in the guide groove serving as the lever operating means 430 is set so that the lever 410 does not rotate with respect to the third gear 230. That is, the shape of the guide groove is an arc shape whose end is deformed into a predetermined shape.

  When the first gear 210 and the third gear 230 rotate by a predetermined amount in this way (see FIG. 8), the direction of rotation of the motor 110 is reversed, and the first gear 210 is rotated in the opposite direction. . The operation of the locking means 400 is reversed. That is, the third gear 230 rotates synchronously with the first gear 210 in the opposite direction (see FIG. 7), and when the first gear 210 and the third gear 230 rotate by a predetermined amount, the third gear 230 is From the state of being locked to the first gear 210 (see FIG. 6), the lever 410 rotates with respect to the third gear 230 in the opposite direction, and the locking of the third gear 230 is released (FIG. 5). reference). And only the 1st gearwheel 210 will be in the state rotated in the reverse direction, and will return to an initial state (refer FIG. 4).

  The rotation amounts of the first decorative body 310 and the second decorative body 320 can be arbitrarily set based on the rotation amount and rotation ratio of each gear and the operation of the locking means 400. Although there is no particular limitation, in the case of this example, when the first decorative body 310 rotates 90 °, the second decorative body 320 rotates with the first decorative body 320, and from there, the first decorative body 320 and the second decorative body 320. When the motor is rotated by 270 °, the motor 110 is reversed.

  According to the driving apparatus of the present example described above, the operation of the decorative body can be set more interesting, and the performance of the watch can be further improved. Since it is thin, it is excellent in design. In addition, it is needless to say that the configuration of each part in the present example can be appropriately changed in design within the technical scope described in the claims, and is not limited to that illustrated in the drawings. For example, the locking means of the present example operates mechanically according to the rotation of the first gear and the third gear, or is configured to be electrically controlled using a solenoid or the like. Is also possible.

  The drive device of the present invention can be used very suitably as a device for decorating a table clock or a wall clock.
