  Embodiments of the present invention will be described below with reference to the drawings. The timepiece device 1 shown in FIGS. 1 and 6 is a table clock formed by visually exposing the mechanical structure of the drive mechanism 200 that drives the hands. As hands, an hour hand 110 and a minute hand 120 are provided.

  The timepiece device 1 includes a dial 300 that has a circular ring, a first base plate 410 that is spaced apart from the back of the dial 300, and a second that is spaced apart from the back of the first ground plate 410. A ground plate 420, a contact mechanism 510 provided on the back of the second ground plate 420, and a time signal generating means 520 that generates a time signal in response to a signal from the contact mechanism 510 are provided. The time signal generating means 520 of this example is a speaker provided inside the pedestal 600. The contact mechanism 510 and the time signal generating means 520 are means for generating a time signal.

  The drive mechanism 200 of the present example is a gear reduction mechanism that rotationally drives the hour hand pipe 210 that supports the hour hand 110 and the minute hand pipe 220 that supports the minute hand 120 with a predetermined period by the power of a motor (not shown). . The drive mechanism 200 is configured by arranging predetermined components on the first base plate 410 and the second base plate 420. Between the dial 300 and the first base plate 410, , And a needle alignment kana 240 meshed with the date wheel 230.

  The needle alignment kana 240 includes a rotation shaft portion 241 penetrating the first ground plate 410 and the second ground plate 420, and an eccentric pin 243 is provided at an end of the rotation shaft portion 241 protruding from the back portion of the second ground plate 420. A knob member 242 is attached. The knob member 242 shown in the figure is fixed to the rotary shaft portion 241 with a set screw. The eccentric pin 243 rotates in synchronization with the needle alignment pinion 240. The positions of the hands 110 and 120 can be corrected by the user operating the knob member 242.

  The first ground plate 410 and the second ground plate 420 are a pair of plates having a predetermined shape, and are fixed to each other by screws through spacers in a state of facing each other, and provided vertically on the upper portion of the base 600. Yes. The pedestal 600 is a battery box that houses a battery serving as a power source for the motor.

  In the case of this example, a first auxiliary ground plate 430 and a second auxiliary ground plate 440 each having a predetermined shape are provided on the back surface of the second ground plate 420. The first auxiliary ground plate 430 is screwed to the second ground plate 420 so as to be in close contact with the important points on the back surface thereof. The second auxiliary ground plane 440 is provided on the back portion of the first auxiliary ground plane 430 with a gap. More specifically, the first auxiliary base plate 430 is fixed by screwing through a spacer while facing the first auxiliary base plate 430 in parallel.

  The first auxiliary base plate 430 is provided with a hole portion 431 that passes through the rotation shaft portion 241 of the needle aligning kana 240. A seat 432 for restricting the amount of postage of the rotary shaft portion 241 is attached to the hole portion 431. The second auxiliary base plate 440 is provided with an opening portion 441 that exposes the knob member 242. The illustrated opening portion 441 is a portion formed by forming the edge of the second auxiliary ground plate 440 into a concave shape. It may be a hole.

  The contact mechanism 510 includes a first contact member 511 made of a leaf spring and a second contact member 512 that the first contact member 511 moves and contacts, and the first contact member 511 contacts the second contact member 512. In this case, a signal is output. Although not particularly limited, in this example, the second contact member 512 is also a leaf spring. When the eccentric pin 243 operates the first contact member 511, the first contact member 511 moves and contacts the second contact member with the rotation of the needle alignment pinion 240. The contact mechanism 510 is provided between the first auxiliary ground plate 430 and the second auxiliary ground plate 440 at the back of the second ground plate 420.

  In this example, the period of the needle alignment can 240, that is, the period of the eccentric pin 243 is 1 hour. The first contact member 511 contacts the second contact member 512 at a predetermined timing once an hour. When the eccentric pin 243 rotates from the state where the first contact member 511 and the second contact member 512 are at a predetermined stop position with a space between each other (see FIG. 5), the eccentric pin 243 becomes the tip of the first contact member 511. The eccentric pin 243 rotates while further elastically deforming the first contact member 511, and the first contact member 511 is biased toward the second contact member 512 (see FIG. 6). When the eccentric pin 243 rotates to some extent from that state, the first contact member 511 is removed from the eccentric pin 243 and simultaneously pushed back by its elastic force, so that the first contact member 511 contacts the second contact member 512. The contact mechanism 510 outputs a signal to the time signal generating means 520 when the first contact member 511 contacts the second contact member 512, and the time signal generating means 520 generates a time signal according to the signal.

  When the contact mechanism 510 and the time signal generating means 520 which are means for generating the time signal are not provided, the first auxiliary ground plate 430, the second auxiliary ground plate 440, and the eccentric pin 243 are omitted. In this case, the timepiece device 1 can be used as a unit having only a basic configuration for driving the hands 110 and 120. That is, such a unit is excellent in versatility such that it is visually excellent and a means for generating a time signal can be easily added.

As described above, in the timepiece device of this example, a means for generating a time signal is rationally provided as an option. 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 speaker is employed as the time signal generating means, but it is also possible to employ a hitting bell device that generates sound by mechanical drive. Further, the time signal generating means can be provided with an exterior case in the timepiece device and disposed in the exterior case.

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