The light emitting unit 24 is a member that emits light toward the cover member 16 and exemplifies an LED (Light Emitting Diode), but is not limited to the LED.

As shown in FIGS. 7 and 8, the cover member 16 includes a transmissive portion 32 (see also FIGS. 5 and 6) that transmits light emitted from each light emitting portion 24 of the plurality of light emitting portions 24, and the cover member 16. The first protrusion 33, the second protrusion 34, the third protrusion 35, and the fourth protrusion 36 protrude from the inner surface 16 </ b> A toward the partition member 26.
The first protrusion 33, the second protrusion 34, the third protrusion 35, and the fourth protrusion 36 will be described in detail later.

As shown in FIGS. 9 to 11, the partition member 26 is a plate-like member formed in a substantially rectangular shape that partitions the light emitted from the plurality of light emitting units 24.
That is, the partition member 26 includes a plurality of light transmitting holes 41 formed at predetermined intervals in the partition member 26, and the first rib 42 and the second rib 43 provided along the peripheral wall 26 </ b> A of the partition member 26. And projections 45 provided between the plurality of light transmitting holes 41.

  In addition, the partition member 26 includes a first flange portion 46, a second flange portion 47, a third flange portion 48, a fourth flange portion 49, and a first flange portion 46 that project from the peripheral wall 26 </ b> A of the partition member 26. The formed first locking hole 52, the second locking hole 53 formed in the second flange 47, the third locking hole 54 formed in the third flange 48, and the fourth flange 49. And a fourth locking hole 55 formed at the bottom.

The translucent hole 41 is a hole penetrating in the thickness direction of the partition member 26 at a portion corresponding to each position of the plurality of light emitting portions 24 in the partition member 26 (see also FIGS. 4 and 12).
Therefore, the light transmitting hole 41 can guide the light emitted from the light emitting unit 24 toward the cover member 16.

The first rib 42 is provided on the circuit board 22 side surface (surface on the circuit board 22 side) 26 </ b> B of the surface of the partition member 26, so that the first rib 42 can contact the circuit board 22 so as to surround the light emitting unit 24. It is a convex part.
The first rib 42 is formed to protrude toward the circuit board 22 with a height dimension H1 with respect to the surface 26B on the circuit board 22 side (see also FIGS. 4 and 12).

The second rib 43 is provided at a position corresponding to the first rib 42 on the cover member 16 side surface (the surface on the cover member 16 side) 26 </ b> C of the surface of the partition member 26, and is a frame that can contact the cover member 16. It is a convex part.

As shown in FIG. 4, the first rib 42 is brought into contact with the circuit board 22 and the second rib 43 is brought into contact with the cover member 16, whereby the partition member 26 is bent toward the circuit board 22 or the cover member 16. Can be prevented.
Therefore, the first rib 42 can be reliably brought into contact with the circuit board 22 in a state of surrounding each light emitting unit 24.
In addition, the second rib 43 can be reliably brought into contact with the cover member 16 in a state of surrounding each light emitting unit 24.

Thereby, the adhesiveness of the 1st rib 42 with respect to the circuit board 22 can fully be ensured, and the light emitted from each light emission part 24 can be favorably guided from the translucent hole 41 to the cover member 16 side.
Therefore, the light emitted from the plurality of light emitting portions 24 can be satisfactorily transmitted from the transmitting portion 32 of the cover member 16 to the outside of the cover member 16 to sharpen the outline of the emitted light.
In addition, since the first rib 42 and the circuit board 22 and the second rib 43 and the cover member 16 can be sufficiently adhered, it is possible to prevent light emitted from each light emitting unit 24 from leaking outside the light emitting range.

Here, the height dimension H <b> 1 of the first rib 42 is set to be larger than the height dimension H <b> 2 of the second rib 43.
Therefore, the elastic deformation amount (elastic deformation allowance) of the first rib 42 is larger than the elastic deformation amount (elastic deformation allowance) of the second rib 43. Thereby, the force by which the partition member 26 is pressed against the cover member 16 is generated, and the adhesion between the partition member 26 and the cover member 16 can be further ensured. Therefore, the outline of the light emitted from the light emitting unit can be made clear. In addition, the first rib 42 can be reliably brought into contact with the circuit board 22 to ensure better adhesion of the first rib 42 to the circuit board 22.

The protrusions 45 are tapered convex portions that are provided between the respective light transmitting holes 41 on the surface 26 </ b> B on the circuit board 22 side and that can contact the circuit board 22 by protruding toward the circuit board 22 side.
Here, for example, a shape such as a hemispherical shape or a cone shape corresponds to the tapered shape.
The projections arranged between the light transmitting holes are brought into contact with the circuit board, so that when the external force is applied to the partition member 26, the partition member 26 is prevented from being bent toward the circuit board 22, and the partition member 26 is covered. The member 16 can be more closely attached.

Further, by making the protrusion 45 tapered, the tip shape of the protrusion 45 can be kept small. Therefore, the distance of the protrusion 45 with respect to each light emitting part 24 mounted on the circuit board 22 can be ensured satisfactorily, and the protrusion 45 can be prevented from contacting each light emitting part 24.
Thereby, it can prevent that the light emission part 24 is hidden by the protrusion 45 when the protrusion 45 contacts each light emission part 24. FIG.
Further, the light emitting units 24 can be prevented from being damaged.

As shown in FIGS. 9 to 11, the first flange portion 46 projects from the first end surface 26 </ b> D of the peripheral wall 26 </ b> A of the partition member 26. A first locking hole 52 is formed in the first flange 46 so as to penetrate along the thickness direction of the partition member 26.
The second flange 47 protrudes from the second end surface 26E facing the opposite side of the first end surface 26D of the peripheral wall 26A of the partition member 26. A second locking hole 53 is formed in the second flange 47 so as to penetrate along the thickness direction of the partition member 26.

The third flange portion 48 projects from the first end surface 26D and the third end surface 26F orthogonal to the first end surface 26D in the peripheral wall 26A of the partition member 26. A third locking hole 54 is formed in the third flange 48 so as to penetrate along the thickness direction of the partition member 26.
The fourth flange 49 protrudes from the fourth end surface 26G facing the opposite side of the peripheral wall 26A of the partition member 26 from the third end surface 26F. A fourth locking hole 55 is formed in the fourth flange portion 49 so as to penetrate along the thickness direction of the partition member 26.

As shown in FIGS. 7 and 13, the first protrusions 33, the second protrusions 34 are formed in the first locking holes 52, the second locking holes 53, the third locking holes 54, and the fourth locking holes 55. The third protrusion 35 and the fourth protrusion 36 are inserted respectively.
The first protrusion 33, the second protrusion 34, the third protrusion 35, and the fourth protrusion 36 are protrusions that protrude from the inner surface 16 </ b> A of the cover member 16 toward the partition member 26.

The first separation dimension L1 (A), L1 (B) between the first engagement hole 52 and the second engagement hole 53 is the second separation dimension L2 (A between the first protrusion 33 and the second protrusion 34). ), L2 (B).
Therefore, the first protrusion 33 is inserted into the first locking hole 52 and the second protrusion 34 is inserted into the second locking hole 53, so that the first protrusion 33 and the second protrusion 34 are separated. The member 26 can be kept pulled in the direction of arrow A.

The third separation dimension L3 between the third engagement hole 54 and the fourth engagement hole 55 is set smaller than the fourth separation dimension L4 between the third protrusion 35 and the fourth protrusion 36.
Therefore, by inserting the third protrusion 35 into the third locking hole 54 and inserting the fourth protrusion 36 into the fourth locking hole 55, the third protrusion 35 and the fourth protrusion 36 are partitioned. The member 26 can be kept pulled in the arrow B direction (that is, the direction orthogonal to the arrow A direction).

A state in which the partition member 26 is pulled in the direction of arrow A by the first protrusion 33 and the second protrusion 34, and the partition member 26 is pulled in the direction of arrow B by the third protrusion 35 and the fourth protrusion 36 Therefore, the partition member 26 can be securely fixed to the cover member 16, and the partition member 26 can be prevented from falling off from the cover member 16. Further, it is possible to prevent the partition member 26 from being bent toward the circuit board 22, and to ensure better adhesion between the partition member 26 and the cover member 16.
Here, the difference between the first separation dimension L1 (A), L1 (B) and the second separation dimension L2 (A), L2 (B) is that when the partition member 26 is pulled and fixed, It is set to such an extent that the protrusion 45 does not deform (for example, about 0.1 mm).
Similarly, the difference between the third separation dimension L3 and the fourth separation dimension L4 is set to such an extent that the translucent hole 41 and the protrusion 45 are not deformed (for example, about 0.1 mm) when the partition member 26 is pulled and fixed. The

  As shown in FIGS. 4, 6, and 8, the diffusion sheet 28 is provided to diffuse the light emitted from each light emitting unit 24.

Note that the electronic apparatus 10 according to the present invention is not limited to the above-described embodiment, and can be changed or improved as appropriate.
For example, in the embodiment, the first protrusion 33 and the second protrusion 34 keep the partition member 26 pulled in the arrow A direction, and the third protrusion 35 and the fourth protrusion 36 indicate the partition member 26 with an arrow. Although the example which fixes the partition member 26 to the cover member 16 by keeping in the state pulled in the B direction has been described, the fixing method is not limited to this.
For example, the partition member 26 can be securely fixed to the cover member 16 simply by keeping the partition member 26 pulled in the direction of arrow A by the first protrusion 33 and the second protrusion 34.

In the embodiment, the first rib 42 and the second rib 43 are provided on the partition member 26, but the present invention is not limited to this. A structure without the second rib 43 may be used. Even in this case, since the first rib 42 is elastically deformed, the surface of the partition member 26 on the cover member 16 side is pressed down, so that the adhesion between the partition member 26 and the cover member 16 can be ensured. However, in this modification, the light emitted from each light emitting unit 24 may leak from between the partition member 26 and the cover member 16 outside the light emission range. Therefore, by providing the second rib 43 as in the embodiment, the second rib 43 and the cover member 16 are reliably brought into contact with each other, and the light emitted from the light emitting unit 24 is prevented from leaking outside the light emission range. It is desirable to do.
In the embodiment, each flange is formed so as to protrude from the cover member 16, but is not limited thereto. For example, you may provide the collar part of the shape which does not protrude from the cover member 16, such as providing a latching hole in the end surface of the cover member 16 and making it a collar part.
In the embodiment, the plurality of light emitting units are arranged, but the present invention is not limited to this. There may be only one light emitting unit.

  Further, the casing, cover member, circuit board, light emitting portion, partition member, first protrusion, second protrusion, light transmitting hole, first rib, second rib, protrusion, and first flange used in the embodiment The shapes and configurations of the second flange portion, the first locking hole, the second locking hole, and the like are not limited to those illustrated, and can be appropriately changed.
