  As shown in the figure, the waterproof case 2 maintains a waterproof structure by connecting a waterproof upper case 2U to a waterproof lower case 2L with screws 8 sandwiching a waterproof packing (not shown).

  Further, rubber feet 9 are provided at three locations of the exterior case 1 that project below the exterior lower case 1L. The rubber feet 9 are attached by fitting the three extension parts 10 projecting downward of the exterior lower case 1L to the waterproof bottom case 2L with screws, and then fitting the rubber feet 9 into the recesses on the lower surface of the extension part 10.

On the upper side surface of the upper waterproof case 2U, a pair of left and right light guides 11 are held by elastic holders 12 made of silicon (see FIGS. 4, 7 and 10), and joined by screws 13. There is.
Further, in the top of the waterproof upper case 2U, an electrostatic sensor as a touch sensor and a light emitting unit (LED) (not shown) are provided.

  FIG. 3 shows a state in which the upper waterproof case 2U is removed, and electronic parts such as the speaker 14 and the lithium ion battery 15 are loaded on the lower waterproof case 2L and hold the lithium ion battery 15 so as to wrap it. A main substrate 21, a pyroelectric sensor substrate 23, an eye substrate 25, and a WIFI communication substrate 27 are stacked on the battery holder 16 by screwing or the like, 24 is a pyroelectric sensor, and 28 is a communication module.

That is, the speaker 14 emits sound downward, and the sound is emitted downward through an opening (not shown) provided in the exterior lower case 1L.
The lithium-ion battery 15 is arranged on the speaker 14, the main substrate 21 is on the back side of the battery holder 16, the pyroelectric sensor substrate 23 is on the upper side of the battery holder 16, and the eye is on the upper side of the front side of the battery holder 16. The board 25 and the communication board 27 are screwed to the lower part of the front side of the battery holder 16.

As described above, the interactive learning machine has functions such as the pyroelectric sensor 24 as a human sensor, an electrostatic sensor, and communication, and various sensors react to turn on the light.
That is, when the human body is sensed by the pyroelectric sensor 24, the voice is sensed from the microphone hole 5, or the top of the head where the light indicator 4 shines so that it changes color or blinks and rises, is touched by the speaker 14. The icon 3 of eyes that emits a voice or appears is shining.

  Next, FIG. 5 shows an enlarged cross section taken along the line AA of FIG. 1A, and FIG. 6 is an enlarged perspective view of a main part including the cross section, which is mounted on the eye substrate 25 as illustrated. As shown by the dotted line in FIG. 2, the part including the pair of left and right LEDs for emitting light is located in the rectangular openings 2a formed on the left and right of the upper upper part of the waterproof upper case 2U, and the pair of left and right guides are provided in the openings 2a. A light body 11 is attached.

As shown in the figure, the light guide 11 has a recess 11a surrounding the portion including the light emitting portion 26 at the base end, and as shown in FIGS. 2, 4, 7, and 10, the recess 11a A protruding portion 11b having a tip protruding obliquely outward is formed.
A reflection surface 11c is formed by plating on the outer peripheral portion of the light guide body 11 excluding the recess 11a and the tip of the protrusion 11b.
An attachment piece 11d is formed on the opposite side of the light guide 11 from the protrusion 11b.

  The light guide body 11 is held so as to be wrapped by the soft elastic holding body 12 made of a silicon material which also serves as a waterproof packing, and as shown in an enlarged view in FIGS. 8 and 9, the upper portion of the waterproof upper case 2U. Waterproofing is achieved by fitting the openings 2a formed on the left and right sides in close contact with each other via the elastic holding body 12.

That is, as shown in FIG. 2, FIG. 4, FIG. 7 and FIG. 10, the substantially cylindrical portion 12a of the elastic holder 12 in a state of wrapping and holding the light guide 11 from the surroundings is fitted tightly into the opening 2a. In this state, the flange portion 12b around the substantially cylindrical portion 12a tightly covers the periphery of the opening 2a to guide the light of the light emitting portion 26 by the LED and reliably waterproof the upper case 2U.
Then, the mounting piece 11d of the light guide 11 is fixed around the opening 2a of the upper waterproof case 2U with the screw 13. In this fixed state, the end surface of the concave portion 11a surrounding the portion including the light emitting portion 26 of the light guide 11 is in close contact with the eye substrate 25.

  In addition, the pair of left and right light guides 11 have the respective mounting pieces 11d positioned therebetween, and the tips of the respective protruding portions 11b are directed toward the side portions separated from each other as shown in the figure. It is in a state of being close to the inside of the case 1U, respectively.

As described above, even if there is a distance between the upper outer case 1U and the upper waterproof case 2U, the light guide 11 is mounted between the outer upper case 1U and the upper waterproof case 2U, so that the light emitting body 26 in the upper waterproof case 2U can be maintained while maintaining the waterproof structure. The light from can be guided to the exterior upper case 1U by the light guide 11 and projected.
That is, first, the light guide 11 is wrapped in the elastic holder 12 and mounted on the upper waterproof case 2U, so that the elastic holder 12 is provided as a packing between the opening 2a of the upper waterproof case 2U and the light guide 11. It is possible to eliminate the gap between the upper waterproof case 2U and the light guide body 11 and to prevent water from entering the upper waterproof case 2U by sandwiching and compressing.

Further, the light from the light emitting body 26 can be guided by bringing the light guide 11 into close contact with the eye substrate 25.
That is, the light guide 11 wraps the light emitting portion 26 in the eye substrate 25 to prevent light from leaking and prevent light from reaching the back surface or the top surface.

Then, the light from the light emitting portion 26 is reflected in the light guide body 11, and the light is projected on the exterior upper case 1U, which forms the shape of the eyes.
Specifically, as shown by the arrow in FIG. 5, the light from the light emitting portion 26 is reflected multiple times by the reflecting surface 11c around the protruding portion 11b that extends outward from the concave portion 11a of the light guide 11, The light is guided from the tip of the protruding portion 11b to the inner surface of the outer upper case 1U, and the inner surface is diffused to the left and right of the upper part of the outer upper case 1U made of a semi-transparent material coated in a cream color and floats up like eyes.

In this way, the light from the light emitting portion 26 is reflected by the light guide 11 and the elastic holder 12 surrounding the light guide 11, and the light can be emitted in the shape of eyes.
Moreover, since the light guide 11 is a component independent of the upper outer case 1U and the upper waterproof case 2U, its shape can be freely changed. By changing the shape of the light guide 11, it is projected on the upper outer case 1U. The silhouette of the reflected light changes, and it is possible to have various shapes and expressions.

  As described above, according to the interactive learning machine of the embodiment, since the light guide 11 that guides the light from the light emitting portion 26 in the upper waterproof case 2U to the outer upper case 1U side is provided, the upper waterproof case 2U and the outside thereof. Even if there is a distance from the outer upper case 1U, the light can be guided from the light emitting portion 26 in the waterproof upper case 2U to the outer upper case 1U.

(Modification)
In the above embodiments, the interactive learning machine is used, but the present invention is not limited to this, and may be another electronic device such as a table clock.
Further, the shapes of the waterproof case, the outer case, the light emitting portion, the light guide body, the elastic holding body, and the like are arbitrary, and it is needless to say that the specific detailed structure can be appropriately changed.
