It is formed in the above position.

In addition, while FIG. 1 and FIG. 2 (d) exemplify four displays as the display unit 2C1, FIGS. 3 and 4 exemplify six light guide pieces 8a, which remain. The purpose is that the two light guide pieces 8a are examples provided in advance, and the number of these light guide pieces 8a is not limited in the application of the present embodiment.

(LED lens mounting structure)
The mounting structure of the LED lens 8 according to the present embodiment will be described with reference to the above configuration. First, the LED lens 8 is placed on the mounting portion 9 of the upper case 2 in the state of FIG. 4A in the following manner. That is, the enclosing portion 12a of the LED lens 8 is located at the position of the shielding plate 10a of the mounting portion 9, the enclosing portion 12b is also located at the position of the shielding plate 10b, and the plurality of supporting portions 8e are also located at the positions of the plurality of gaps 10d. The shaft portion 8b of the LED lens 8 is placed on the bearing portion 11 of the mounting portion 9 so as to come to.

Then, in this state, the light guide piece 8a of the LED lens 8 is rotated about 90 degrees inward of the upper case 2 around the shaft portion 8b to obtain the state shown in FIG. 4 (b). At this time, since the protruding engaging portions 8d1 and 8d2 can be used as knobs, the rotation can be smoothly performed. FIG. 5 shows this state in relation to the upper case 2. As shown in FIG. 5, by rotating the LED lens 8 by 90 degrees, the engaging portions 8d1 and 8d2 of the LED lens 8 are engaged with each other by covering the shielding plates 10a and 10b at both ends of the mounting portion 9 in the cavity. The support portion 8e of the LED lens 8 is fitted into the gap 10d of the mounting portion 9. When rotating, the LED lens 8 does not interfere with the shielding plates 10, 10a, 10b by the enclosing portions 12, 12a, 12b, and rotates smoothly.

As one cross section in this state, the cross-sectional view taken along the line AA of FIG. 5 is shown in FIG. As shown in FIG. 6, the first end 8a1 of the plurality of light guide pieces 8a of the LED lens 8 is positioned above each LED 7 provided on the control substrate 5. Further, the second end 8a2 of the light guide piece 8a is positioned inside the display unit 2C1 provided on the front surface 2C of the upper case 2.

In this way, the LED lens 8 can be mounted at an accurate position only by rotating the shaft portion 8b on the bearing portion 11 of the mounting portion 9, but the bearing portion 11 is the outer edge of the opening 2a of the upper case 2 (FIG. Since it is formed at the upper middle end), it is extremely easy to align the LED lens 8 with the mounting portion 9.

Further, by rotating the LED lens 8 inward of the upper case 2 around the shaft portion 8b, the engaging portions 8d1 and 8d2 engage with the shielding plates 10a and 10b at both ends, so that the housing 1 can be turned upside down. The LED lens 8 does not come off from the upper case 2 even if it is tilted. Moreover, when it is necessary to remove it, it can be easily removed because it is not fixed by screws or adhesives.

Further, the connecting portion 8c is formed on the upper part of the light guide piece 8a. That is, since the connecting portion 8c is formed at a position where the light emitted from the LED 7 is weakened, it is possible to prevent the illumination from leaking from the gap 10d between the connecting portion 8c and the shielding plate 10.

A storage device (for example, SSD) (for example, SSD) mounted inside the housing 1 can be attached to or removed from the bottom surface 2A (FIG. 2A) of the upper case 2 of the housing 1. An opening 2a for the purpose is provided. The base member 3 is attached to the opening 2a and is locked together with the housing 1 by a locking tool (not shown) via the locking plate 6. The base member 3 is provided with an insertion hole 3b having a protrusion 3c and a rectangular insertion hole 3a at a position facing the back surface 2B side when viewed from the insertion hole 3b.

(Locking plate)
Here, the locking plate 6 will be described with reference to FIG. 7. As shown in FIG. 7, the locking plate 6 is configured in a U shape in a side view, and has a first surface 6a, a second surface 6b facing the first surface 6a, a first surface 6a, and a second surface. It is composed of a third surface 6c connecting the surfaces 6b. Here, an example is shown in which the first surface 6a is short and the second surface 6b is long. The locking plate 6 is made of a sheet metal having a certain strength.

The first surface 6a of the locking plate 6 has an engaging hole 6d engaged with the protrusion 3c of the insertion hole 3a of the base member 3, and the second surface 6b overlaps with the fitting hole 2c of the back surface 2B of the upper case 2. The first locking hole 6e and the second locking hole 6f (which are selectively used depending on whether a single electronic device is locked or a plurality of electronic devices are stacked and locked) are the third. The surface 6c is provided with a first mounting hole 6h and a second mounting hole 6i used for screwing the base member 3.

The first mounting hole 6h and the second mounting hole 6i on the third surface 6c may be one of the second mounting holes 6i on the side closer to the second surface 6b. Further, the width of the third surface 6c may be partially formed longer than the major axis of the insertion hole 3a so that the locking plate 6 does not fall from the insertion hole 3a of the base member 3 into the upper case 2. In FIG. 2A, a locking plate 6 is used in which only the second mounting hole 6i is provided and the width of the third surface 6c is partially longer than the major axis of the insertion hole 3a.

As shown in FIG. 2A, the locking plate 6 configured in this way has a first surface 6a inserted into an insertion hole 3a provided in the base member 3, and a second surface 6b inserted into the base member 3. It is inserted into the provided insertion hole 3b. Then, the third surface 6c is screwed to the base member 3 via the second mounting hole 6i by the screw 4 which is the fastening means.

Note that FIG. 7 shows an example in which an inclined portion 6 g extending inward from the tip of the first surface 6a is further provided. The inclined portion 6g is intended to be hooked on the insertion hole 3a when a plurality of electronic devices are stacked and the engagement hole 6d cannot be engaged with the protrusion 3c of the insertion hole 3a.
