Further, the slide switch operation unit 5 has a knob holding unit 52, a substrate holding unit 53, and a substrate contact rib 54 on the surface provided on the substrate 4 side of the base unit 50.

  The knob 51 is exposed to the outside from the opening 14 of the upper case 1 and is used by the user of the electronic device 100 to grip and slide the slide switch operation unit 5.

  The lower case side surface contact rib 55 is a portion that contacts the inner side surface of the lower case 2 and is formed from the base portion 50 in a semi-cylindrical shape parallel to the slide direction of the slide switch operation unit 5 whose axial direction moves in the Y direction in the figure. The lower case 2 is provided so as to protrude to the inner surface side.

  Further, the upper case contact rib 56 is a portion that contacts the inner surface of the upper case 1, and the base portion 50 is formed in a semi-cylindrical shape parallel to the sliding direction of the slide switch operating portion 5 whose axial direction moves in the Y direction in the figure. To the upper case 1 so as to protrude to the inner surface side.

  The lower case bottom surface contact rib 58 is a portion that contacts the inner bottom surface of the lower case 2 and is lower from the base portion 50 in a direction orthogonal to the slide direction of the slide switch operating portion 5 whose axial direction moves in the Y-axis direction in the figure.

Moreover, you may provide an opening sealing rib also in the both ends of the lower case side surface contact rib 55. FIG. Intrusion of dust or the like into the upper case 1 and the lower case 2 can be prevented more reliably.

  The knob holding portion 52 is provided on the surface of the base portion 50 on the substrate 4 side at a position corresponding to the knob portion of the slide switch 43 of the substrate 4, and has two protrusions that hold the knob portion of the slide switch 43 on the substrate 4. Part. When the knob 51 is moved in the sliding direction by the user of the electronic device 100, the slide switch operating unit 5 operates the slide switch 43 by causing the knob holding unit 52 to slide the knob part of the slide switch 43 together.

  The substrate sandwiching portion 53 is two protrusions provided on the surface of the base portion 50 on the substrate 4 side, and sandwiches and sandwiches the substrate 4 with the knob sandwiching portion 52.

It is provided to be at least L2. With such a configuration, it is possible to prevent the slide switch operation unit 5 from rattling in the X direction in the drawing, and the substrate 4 can support the slide switch operation unit 5 more stably.

  The substrate contact rib 54 is a rib that is provided between the knob holding portion 52 and the substrate holding portion 53 and protrudes in a semi-cylindrical shape whose axial direction is parallel to the sliding direction of the slide switch operation portion 5. Since the slide switch operation unit 5 has the substrate contact ribs 54, the contact area with the substrate 4 is reduced as compared with the case where the base unit 50 is in direct contact with the substrate 4, and smooth movement in the sliding direction is possible. It has become.

  The slide switch operation unit 5 includes the base unit 50, knob 51, knob clamping unit 52, substrate clamping unit 53, substrate contact rib 54, lower case side surface contact rib 55, lower case bottom surface contact rib 58, and upper case contact described above. The rib 56 and the opening sealing rib 57 are integrally formed.

  Here, the portions where the lower switch side contact rib 55, the lower case bottom contact rib 58, the upper case contact rib 56, and the substrate contact rib 54 of the slide switch operation unit 5 are in contact with the upper case 1, the lower case 2 and the substrate 4 are respectively shown. For example, when molding with a mold, it is preferable to reduce the surface roughness by polishing or the like corresponding to each part of the mold. The slide switch operation unit 5 can operate more smoothly. Similarly, it is preferable that the upper case 1 and the lower case 2 polish the portions of the mold corresponding to the respective portions that contact the upper case contact rib 56 and the lower case side contact rib 55, respectively. The slide switch operation unit 5 can operate more smoothly.

  FIG. 8 is a cross-sectional view of a main part of the electronic device 100 according to the embodiment, and is an XZ cross-sectional view passing between the knob holding portions 52 of the slide switch operation unit 5.

  As shown in FIG. 8, the slide switch operation unit 5 is arranged between the end of the substrate 4 and the inner surfaces of the upper case 1 and the lower case 2 by the upper case 1, the lower case 2 and the substrate 4 in the Y direction in the figure. Is supported so as to be movable. In addition, the slide switch operation unit 5 is supported by the substrate 4 when the knob holding unit 52 and the substrate holding unit 53 to be sandwiched sandwich the substrate 4. Furthermore, the base part 50 of the slide switch operation part 5 is supported by the support part 17 provided in the upper case 1. Further, a guide portion 18 is formed linearly in the Y-axis direction on the lower case 2, and the lower case bottom surface contact rib 58 is guided by the guide portion 18. The slide switch operation unit 5 is thus supported by the upper case 1, the lower case 2, and the substrate 4, and the operation is guided by the guide unit 18, so that, for example, backlash in the X direction during the slide operation is reduced. Yes.

  Further, the slide switch operation unit 5 includes an upper case contact rib 56, a lower case side surface contact rib 55, and a substrate contact rib 54 at the contact portions with the upper case 1, the lower case 2, and the substrate, respectively, so that the slide switch operation unit 5 can be Smooth operation is possible without rattling.

  Note that there is a gap S between the upper end portion of the slide switch operation portion 5 and the support portion 17 of the upper case 1. For example, even when the upper case 1 and the lower case 2 are sandwiched and pressed, the slide switch operation portion 5 is provided so as not to contact the support portion 17 of the upper case 1. Therefore, for example, even when the upper case 1 and the lower case 2 are pressed in the Z direction, the slide operation of the slide switch operation unit 5 does not become heavy.

  According to the embodiment described above, it is possible to realize a slide-type switch that can be operated smoothly, and an electronic device 100 including the switch, by suppressing the backlash at the time of the slide operation of the slide switch operation unit 5.
