It is an upper surface see-through explanatory view showing a timepiece device according to the embodiment of the present invention. It is a rear view which shows the circuit board concerning the Example of this invention.

  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 7 includes a movement 200 for driving a pointer, a circuit board 300, and a speaker 400 inside a case 100. The timepiece device 1 is a unit that is mounted on a predetermined housing and constitutes an hourly timepiece.

  The case 100 is formed by assembling a first case member 110 constituting the front side thereof and a second case member 120 constituting the back side thereof. The first case member 110 and the second case member 120 are injection-molded members molded in a predetermined shape, and are configured to be assembled by screwing or hooking each other. Further, in the case 100, the movement 200 is positioned between the first case member 110 and the circuit board 300, and the speaker 400 is positioned between the second case member 120 and the circuit board 300. . That is, the positional relationship inside the case 100 is the movement 200, the circuit board 300, and the speaker 400 in order from the front side.

  The movement 200 includes a pointer pipe 210 for attaching a pointer on the front side thereof, and a needle alignment knob 220 for adjusting the rotational position of the pointer on the rear side thereof.

  The movement includes a motor and a speed reduction mechanism including a gear train connected to the motor, and the pointer pipe 210 is driven by the motor via the speed reduction mechanism. The needle alignment knob 220 is connected to a speed reduction mechanism, and when this is rotated, the power is transmitted to the speed reduction mechanism, and the pointer pipe is forcibly driven. The motor and the speed reduction mechanism are housed in a thin movement case 201. The pointer pipe 210 protrudes to the front side of the movement case 201. The needle alignment knob 220 protrudes on the back side of the movement case 201.

  The circuit board 300 is provided with a required circuit for controlling the timepiece device 1. A plurality of operation switches are mounted on the back side of the circuit board 300. In the illustrated example, a dial-type first operation switch 311, a slide-type second operation switch 312 and a third operation switch 313, and a push-type fourth operation switch 314 are provided.

  The timepiece device 1 is configured to generate a notification sound from the speaker 400 when a predetermined time arrives. In this example, the first operation switch 311 adjusts the volume of the notification sound. The second operation switch 312 switches the notification sound ON / OFF. The third operation switch 313 selects a type of notification sound such as an alarm sound or a melody. When pressed, the fourth operation switch 314 generates a notification sound that is adjusted and selected regardless of the time. However, the function and type of each operation switch can be arbitrarily set as necessary, and are not particularly limited.

  In the case of this example, the first case member 110 is provided with a first hole portion 111 that exposes the pointer pipe 210 of the movement 200.

  The second case member 120 includes a second hole 121 that exposes the needle alignment knob 220, a plurality of third holes 122 that expose the operation switches 311, 312, 313, and 314, and the circuit board 300. A first female screw boss 123 for screwing the movement 200, a second female screw boss 124 for screwing the movement 200, a speaker mounting portion 125 for mounting the speaker 400, and a sound hole 126 for diffusing the sound of the speaker 400 to the outside of the case 100. And a battery box 127 for storing batteries. The battery box 127 extends from the second case member 120 to the inside of the first case member 110, and has a configuration in which a battery is taken in and out from the lower back of the second case member 120.

  Further, the circuit board 300 is provided with a first insertion portion 301 for inserting the needle alignment knob 220 and a second insertion portion 302 for inserting the second female screw boss 124.

  The assembling work of the timepiece device 1 is as follows. First, a battery electrode is provided on the battery box 127 of the two case member 120. When a plurality of batteries are housed in the battery box 127, the battery electrodes are connected with lead wires as necessary. Then, the wiring of the movement 200, the speaker 400, and the battery electrode are soldered and connected to the circuit board 300.

  Next, the second case member 120 is placed on the work table, and the speaker 400 is mounted on the speaker mounting portion 125. The illustrated speaker mounting part 125 is provided with a cylindrical rib into which the speaker 400 is fitted inside the second case member 120. The speaker 400 is mounted by fitting into the speaker mounting portion 125 and by screwing a flange bolt into a female screw portion provided in the vicinity of the speaker mounting portion 125 so as to prevent detachment.

  Next, the circuit board 300 is screwed to the first female screw boss 123 while passing the operation switches 311, 312, 313, 314 through the third holes 122. A certain amount of space is formed between the second case member 120 and the circuit board 300 according to the height of the first female screw boss 123. This space is configured to act as an enclosure for the speaker 400.

  Then, the movement 200 is screwed to the second female screw boss 124 while the needle alignment knob 220 is passed through the first insertion portion 301 and the second hole portion 121. In this state, the movement 200, the circuit board 300, and the speaker 400 are supported by the second case member 120.

  Thereafter, the first case member 110 is assembled to the second case member 120 while the pointer pipe 210 is passed through the first hole 111.

  According to such a configuration, it is possible to sequentially assemble each component without changing the direction of the second case member 120. There is an advantage that the assembling work becomes easy.

  Further, by providing the battery box 127 on the second case member 120 as in the present example, it is not necessary to separately prepare a member constituting the battery box 127, so that the number of parts can be reduced. In particular, since the lead wire provided in the battery box 127 and the soldered portion of the lead wire are covered with the first case member 110 together with the movement 200 and the circuit board 300, there is an advantage that the appearance is improved.

  In the case of this example, the first case member 110 is provided with a plurality of concave portions 110 a that expose a part of the front side of the circuit board 300. A portion of the circuit board 300 exposed in each recess 110a is provided with a terminal 300a for mounting a sensor for detecting an external environment and a terminal 300b for connecting an external lead wire.

  As a sensor for detecting an external environment, for example, a photo sensor is provided. Brightness is detected by a photo sensor, and this is fed back to the control of the timepiece device 1.

  Further, as an external lead wire, for example, a lead wire of a switch different from the operation switch described above is connected. According to such a configuration, it is possible to provide a switch at an important point of a housing where the timepiece device 1 is mounted as a unit, and to connect the lead wire of the switch to the circuit board 300.

  As described above, the timepiece device of this example is very reasonably configured as a unit constituting the timepiece timepiece. 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 timepiece device of the present invention can be used very suitably as a unit constituting an analog type timepiece.
