A plurality of first decorative bodies 310 respectively driven by a plurality of second gears 220, a plurality of second decorative bodies 320 respectively driven by a plurality of fourth gears 240, and a third gear 230. And locking means 400 for locking to the. The first gear 210 is provided with a decorative rotating plate 211, and the first decorative body 310, the second decorative body 320, and the decorative rotating plate 211 are configured to be driven by a common driving unit 100. Yes.

  The first gear 210, the second gear 220, the third gear 230, the fourth gear 240, and the driving unit 100 are provided between the substrate body 500 and the case body 600 attached to the front surface of the substrate body 500. A cylindrical rib 510 is provided in the center of the substrate body 500, and the first gear 210 and the third gear 230 are rotatably attached to the cylindrical rib 510. The case body 600 is a member having a predetermined shape that is disposed on the front side of the timepiece 900. A movement 920 for driving the pointer 910 is provided at the center of the back surface of the case body 600.

  The first decorative body 310 is integrally provided with a hollow boss-shaped first shaft portion 710, and the fourth gear 240 is integrally provided with a second shaft portion 720 that can be inserted into the first shaft portion 710. . The first decorative body 310 is coupled with the first shaft portion 710 fixed to the first gear 210. The second decorative body 320 is connected with the second shaft portion 720 fixed to the fourth gear 240. The second gears 220 and the fourth gears 240 are circularly arranged at a predetermined pitch around the rotation axes of the first gear 210 and the third gear 230, and the rotation axes are parallel to each other. Yes. Furthermore, the rotation axis of the second decorative body 320 is provided so that every other rotation axis is at the same position as the rotation axis of the first decoration body 310, and each first shaft portion 710 has the same rotation axis. The second shaft portion 720 of the second decorative body 320 is inserted. Necessary through holes are provided in appropriate portions of the case body 600.

  The second gear 220 and the first decorative body 310 rotate around the first shaft portion 710, and the fourth gear 240 and the second decorative body 320 rotate around the second shaft portion 720. That is, when the first gear 210 rotates, the second gear rotates, and the first decorative body 310 rotates synchronously with the second gear. When the third gear 230 rotates, the fourth gear rotates, and the second decorative body 320 rotates synchronously with the fourth gear. The decorative rotating plate 211 is provided on the front side of the first gear 210 and rotates synchronously with the first gear 210.

  The locking means 400 is configured to rotate the third gear 230 in synchronization with the first gear 210 by locking the third gear 230 to the first gear 210. When the third gear 230 is locked to the first gear 210 by the locking means 400, the first decorative body 310 and the second decorative body 320 are driven. When the locking of the third gear 230 is released, the first decorative body 310 is driven and the second decorative body 320 is not driven.

  The structure of the locking means 400 is not particularly limited, but in this example, as shown in FIGS. 7 to 13, the lever 410 provided on one of the first gear 210 and the third gear 230, and the lever 410 A lever fitting portion 420 provided on the other side and lever operating means 430 for operating the lever 410 are provided. When the lever 410 is fitted to the lever fitting portion 420 in accordance with the operation of the lever operating means 430, the third gear 230 is locked to the first gear 210. When the lever 410 is disengaged from the lever fitting portion 420, the locking of the third gear 230 is released.

  The illustrated lever 410 is pivotally supported on the third gear 230 by a male screw part 411. 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. 9). When the first gear 210 rotates and the lever fitting portion 420 approaches the lever 410 (see FIG. 10), 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 manner, 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. 11).

  When the first gear 210 further rotates, the third gear 230 rotates in synchronization with the first gear 210 (see FIG. 12). 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.

  Thus, when the first gear 210 and the third gear 230 rotate by a predetermined amount (see FIG. 13), the motor 110 is temporarily stopped there. Further, this time, the rotation direction 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. 12), 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. 11), the lever 410 rotates in the opposite direction to the third gear 230, and the locking of the third gear 230 is released (FIG. 10). reference). Then, only the first gear 210 rotates in the opposite direction, and returns to the initial state (see FIG. 9). The locking means 400 of this example operates mechanically according to the rotation of the first gear 210 and the third gear 230, or is electrically controlled using a solenoid or the like. It is also possible to configure.

  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 not particularly limited, in this example, when the first decorative body 310 rotates 90 °, the second decorative body 320 rotates together with the first decorative body 320, and from there, the first decorative body 320 and the second decorative body 320 are rotated. Is configured to stop and reverse when the motor rotates 270 °.

  Next, the form of the drive device 1 of this example will be described. When the driving device 1 of this example is viewed from the front, the plurality of first decorative bodies 310 are positioned in front of the decorative rotating plate 211, and the plurality of second decorative bodies 320 are positioned in front of the plurality of first decorative bodies 310. ing.

  The driving device 1 is configured to set a first stop form and a second stop form in which a plurality of first decorative bodies 310, a plurality of second decorative bodies 320, and a decorative rotating plate 211 are stopped at predetermined positions. When the first gear 210 is rotated forward, the form changes from the first stop form to the second stop form, and when the first gear 210 is rotated reversely, the form changes from the second stop form to the first stop form. It has become. A sensor 501 for detecting the rotational position of the first gear 210 is provided at a key point of the substrate body 500 or the case body 600, and the motor is controlled according to the rotational position of the first gear 210.

  In the first stop mode, the plurality of first decorative bodies 310 cover the decorative rotating plate 211, and the plurality of second decorative bodies 320 have a ring shape (see FIG. 1). The plurality of second decorative bodies 320 constitute an index of the timepiece 900 in a state of a ring shape.

  FIG. 14 shows the first decorative body 310 in a state of covering the decorative rotating plate 211. Each first decorative body 310 includes a first edge 311 that forms an arc centered on the rotation axes of the first gear 210 and the third gear 230, and a second edge centered on the rotation axis of the first decorative body 310. Part 312.

  FIG. 15 shows the second decorative body 320 in a ring shape. Long and short circumferences corresponding to the rings are alternately arranged, and their positions are shifted in the front-rear direction to avoid mutual interference during rotation.

  In the second stop form, the plurality of first decorative bodies 310 rotate 360 ° to cover the decorative rotating plate 211 at the same position as the first stop form, and the plurality of second decorative bodies 320 rotate 270 ° and are non-rotated. It has a ring shape (see FIG. 4).

  During the shape change, the locking means 400 operates as described above, the plurality of first decorative bodies 310 are driven, and the plurality of second decorative bodies 320 are not driven (see FIG. 2). The first decoration 310 and the plurality of second decoration bodies 320 are driven (see FIG. 3), and the decoration rotating plate 211 is exposed from the back of the plurality of first decoration bodies 310 while rotating.

  That is, the timepiece 900 of this example displays the time in the first stop mode at normal times (see FIG. 1). When the predetermined time comes or when the user operates a monitor switch (not shown), the driving device 100 is driven. According to this drive 100, first, the first decorative body 310 is driven and the second decorative body 320 is not driven (see FIG. 2), and when the first decorative body 310 is rotated 90 °, the locking means 400 The third gear 230 is locked to the first gear 210, and the first decoration 310 and the second decoration body 320 are driven (see FIG. 3). From there, the first decoration 310 and the second decoration body 320 rotate synchronously, and when they rotate 270 °, the second stop form is reached (see FIG. 4). Furthermore, when the motor 110 is temporarily stopped in the second stop mode and then reverse rotation is started, the driving is reversed, and the motor 110 is stopped when returning to the first stop mode.

  In addition, since the 1st decoration body 310 covers the decoration rotation board 211, it becomes a comparatively large thing. For this reason, in this example, in order to stabilize the driving of the first decorative body 310, a guide member that restricts the blurring in the front-rear direction of the edge portion of the first decorative body 310 is disposed. As a guide member, a cylindrical pipe 921 centering on the rotation axis of the pointer 910 is provided on the movement 920, and a first pulley 810 is disposed on the cylindrical pipe 921. The second pulley 820 is disposed on the second shaft portion 720 that is not inserted through the first shaft portion 710. The blur in the front-rear direction of the edge of the first decorative body 310 is restricted by the first pulley 810 and the second pulley 820.

  According to the driving device 1 of the present example described above, the operation of the decorative body can be set more interesting, and the performance of the timepiece can be further improved. Compared with a conventional drive device, a three-dimensional movement can be obtained. In particular, the decorative rotating plate 211 is exposed at the time of driving, and the index indicating the ring shape is separated, so that the change at the time of driving from the normal time becomes dramatic, and the unexpectedness increases. 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.

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