  Now, the movement for driving the pointer is provided behind the dial, and the pointer pipe passes through the dial. Here, in the case of the dial plate formed by arranging a plurality of prisms as described above, it is necessary to avoid buffering between the prism and the pointer pipe when the prism is rotated. The one disclosed in Patent Document 1 has a configuration in which one of the prisms is divided in the axial direction of the rotation shaft, and a pointer pipe is disposed in the gap. Moreover, what was disclosed by patent document 2 does not have the prism arranged around the pointer pipe. In other words, the conventional one has the disadvantage that the degree of freedom in designing the dial plate is restricted in order to avoid buffering, and further ingenuity is required to obtain a more unusual and bold design. . The present invention has been made in view of such circumstances, and an object of the present invention is to provide a timepiece device in which the movement of the dial is more rationally configured to improve decorativeness.

  The invention described in claim 1 of the present application includes a movement for driving a pointer and a dial plate driving mechanism for driving a dial plate, wherein the dial plate is formed by arranging a plurality of prisms, The movement is arranged behind the dial, and a pointer pipe that supports the pointer extends from the gap between the prisms to the front of the dial, and the dial driving mechanism includes the plurality of dials. The prism is rotated to change the form of the dial, and the rotation axis of the prism is moved away from the pointer pipe.By moving the rotation axis, the rotation of the prism is performed. It is a timepiece device configured to avoid buffering between a prism and the pointer pipe.

  According to the present invention, it is possible to obtain a timepiece device in which the movement of the dial is more rationally configured to improve the decorativeness.

  Embodiments of the present invention will be described below with reference to the drawings. The timepiece device 1 of the present example shown in FIGS. 1 to 6 is an analog type in which a movement 200 for driving a pointer 201 and a dial plate driving mechanism 400 for driving a dial plate 300 are arranged inside a housing 100. It is a table clock or a wall clock.

  The dial plate 300 of this example is formed by arranging a plurality (four in the illustrated example) of triangular prisms 310 in the left-right direction, and the form changes by simultaneously rotating these triangular prisms 310 in the horizontal direction. It is the composition to do. An opening 110 is provided on the front surface of the housing 100, and the plurality of triangular prisms 310 are exposed through the opening 110. The plurality of triangular prisms 310 stop at positions where their side surfaces are parallel to the opening 110, and the dial pattern has a different configuration each time the triangular prism 310 rotates 120 ° (FIG. 1). Thru | or FIG. 3).

  The timing for rotating the triangular prism 310 is not particularly limited, but in the case of this example, the dial plate driving mechanism 400 is operated by a control unit (not shown) and automatically rotates at the correct time. Alternatively, a switch for operating the dial plate driving mechanism 400 may be provided so that the user can rotate it at an arbitrary timing.

  The movement 200 is arranged behind the dial 300, and a pointer pipe 210 that supports the pointer 201 is extended from the gap between the triangular prisms 310 to the front of the dial 300. The pointer 201 is supported at the tip of the pointer pipe 210 and is driven to rotate in front of the dial 300.

  The dial driving mechanism 400 rotates the plurality of triangular prisms 310 to change the shape of the dial 300 and moves the rotation shaft 311 of the triangular prism 310 away from the pointer pipe 210. By moving the rotation shaft 311, buffering between the triangular prism 310 and the pointer pipe 210 during the rotation of the triangular prism 310 is avoided. That is, according to the present example, the triangular prism 310 and the pointer pipe 210 are in a positional relationship in which they are buffered when the triangular prism 310 rotates without moving the rotating shaft 311. Therefore, in order to avoid buffering between the triangular prism 310 and the pointer pipe 210, the rotation shaft 311 of the triangular prism 310 is moved to avoid such interference.

  Below, the structure of the dial plate drive mechanism 400 of this example is explained in full detail. 5 shows when the dial plate driving mechanism 400 is stopped, and FIG. 6 shows when the dial plate driving mechanism 400 is driven. The dial plate driving mechanism 400 has a configuration in which a pair of supports 410 that respectively support the rotation shaft 311 of the triangular prism 310 are slidable in the left-right direction with respect to the housing 100 and the supports 410 are moved. ing. The housing 100 is provided with a rail 120 that supports the support 410 so as to be slidable. The rotation shaft 311 of the triangular prism 310 is supported perpendicular to the support body 410. The pair of supports 410 are provided symmetrically with respect to the pointer pipe 210. When the triangular prism 310 is rotated, the right support 410 moves to the right and the left support 410 moves to the left.

  The plurality of triangular prisms 310 and the pair of supports 410 are configured to follow the drive gear 420. A predetermined number of driven gears 312 are fixed to each rotary shaft 311, and the drive gear 420 is meshed with a driven gear 312 fixed to the rotary shafts 311 of the two central triangular prisms 310 sandwiching the pointer pipe 210. Yes. The drive gear 420 is an output part of a motor (the whole is not shown), and the distance from the meshed driven gear 312 is regulated by the link body 421. According to the link body 421, the drive gear 420 moves in the front-rear direction when the pair of support bodies 410 move in the left-right direction. That is, even if the support body 410 moves, the meshing state with the predetermined driven gear 312 is maintained. Further, for each support 410, an intermediate gear 430 that meshes with each other is provided between predetermined driven gears, and when the drive gear 420 rotates, a plurality of triangular prisms 310 rotate simultaneously. ing. The intermediate gear 430 is rotatably supported with respect to the support body 410.

  A pair of support body 410 is urged | biased in the direction which mutually approaches by the elastic body 411 which connects them. In addition, cam bodies 440 having a predetermined shape are symmetrically provided on the rotation shafts 311 at both the left and right ends, and each cam body 440 is provided with a cam body engaging portion provided at an important point of the casing 100. 130 is engaged. When each rotating shaft 311 rotates, the triangular prism 310 fixed to them rotates, and each cam body 440 extends the elastic body 411 and pushes the interval between the pair of support bodies 410 in the left-right direction. That is, when the rotating shaft 311 moves in a direction away from the pointer pipe 210, buffering between the triangular prism 310 and the pointer pipe 210 is avoided. When the rotating shaft 311 further rotates, the pair of support bodies 410 returns to a predetermined stop position by the elastic force of the elastic body 411.

  According to the timepiece device of this example described above, it is possible to obtain a timepiece device in which the movement of the dial is more rationally configured to improve the decoration. 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, in this example, a triangular prism is adopted as a member constituting the dial, but other polygonal pillars can be adopted. In addition, the dial plate driving mechanism of this example is excellent in that a plurality of triangular prisms and a pair of supports are driven by a single power source. Alternatively, a power source that rotates a triangular prism and a support are provided. It is also possible to provide a driving power source.

  The timepiece device of the present invention can be suitably used as a table clock or a wall clock having excellent decorativeness.
