Guide walls 12 and 12 are formed inwardly on the inner walls 11 and 11 of the recess 8 facing each other, and an elongated hole (first guide groove) 13 penetrating substantially parallel to the bottom surface 10 is formed. Are formed. Further, on the bottom surface 10 of the concave portion 8, a long hole 14 is formed so as to partially penetrate into the long hole 13 of the inner wall 11.

On the other hand, the L-shaped lid 9 is shown in FIGS.
As shown in (b), the first plate portion 15 for closing the open surface of the concave portion 8 on the side of the surface plate 6 and the second plate portion 16 for closing the open surface of the concave portion 8 on the side surface plate 7 side. Is integrally formed into a substantially L shape.

Further, the L-shaped lid 9 integrally has a pair of side plates 17 on both sides thereof across the first plate portion 15 and the second plate portion 16, and the L-shaped lid 9 is provided as a device. The side plates 17 are provided so as to be adjacent to the inner walls 11 of the recesses 8 when mounted on the housing 1.

At both ends of the side plate 17 near the leading edge on the second plate portion 16 side, there are rotation projections (shafts) 18 projecting laterally (in the direction orthogonal to the paper surface in FIG. 3B). The curved guide rails (second guide grooves) 19 are provided while being respectively provided.

In the L-shaped lid 9, the rotation projection 18 of the side plate 17 is loosely fitted in the elongated hole 13 of the inner wall 11 of the recess 8, and the guide projection 12 of the inner wall 11 of the recess 8 is loosely mounted on the guide rail 19. By being arranged so as to be fitted, it is rotatably attached to the apparatus housing 1. Side plate 1 of L-shaped lid 9
A part of 7 can be inserted into the elongated hole 14 of the bottom plate 10 of the recess 8 by the turning position of the L-shaped lid 9.

Although not shown, the L-shaped lid 9
A protruding lock claw is provided inside the first plate portion 15 in the vicinity of the tip end thereof, and a lock claw receiving portion is provided at a position of the recess 8 corresponding to the lock claw. Part 1
By pressing the position corresponding to the lock claw 5 from the outside to insert the lock claw into the lock claw receiving part, the lock claw is fixed to the lock claw receiving part, and further released after the pressing is released. As a result, the lock claw is released from the lock claw receiving portion and is pushed out.

Next, the operation of the L-shaped lid 9 will be described with reference to FIG. First, as shown in FIG. 3A, when the L-shaped lid 9 is closed, the guide projection 12
Is located at one end of the guide rail 19, and the rotation protrusion 18 is located at one end of the slot 13. In addition, a part of the side plate 17 of the L-shaped lid 9 is formed in the long hole 1 of the bottom surface 10 of the recess 8.

Rotates about the rotation protrusion 18.

At this time, due to the interference of the guide projection 12 with the guide rail 19, the guide projection 12 relatively moves to the other end side along the guide rail 19 as shown in FIG. At the same time, the rotation projection 18 moves toward the other end of the elongated hole 13.

When the L-shaped lid 9 is further rotated, the rotation projection 18 reaches the other end of the elongated hole 13 while rotating, and as shown in FIG. Further rotation is restricted in a state in which the first plate portion 15 is positioned substantially in the same plane as the side surface plate 7.

In this way, the rotation protrusion 18 of the L-shaped lid 9
Is inward as much as the elbow portion (intersection of the first plate portion 15 and the second plate portion 16) 20 of the L-shaped lid 9 projects outward as the L-shaped lid 9 rotates. Because it moves, elbow 20
Will move along substantially the same plane as the side plate 7.

Therefore, the L-shaped lid 9 is necessary even if the apparatus housing 1 is installed on a table or the like with the side plate 7 facing downward, or another device is installed adjacent to the side plate 7. It can be opened and closed according to your needs. Therefore, there is no restriction on the installation direction or installation location of the device, and an information processing device that can realize a layout according to the user's request is provided.

Since the elongated hole 13 of the inner wall 11 is connected to the elongated hole 14 of the bottom surface 10, there is a concern that the rotation projection 18 may move to the inner side. The tip edge of the second plate portion 16 of the lid 9 moves while contacting the bottom surface 10 of the concave portion 8, and such a situation does not occur.

Further, by making the elongated hole 13 of the inner wall 11 into a linear shape and curving the guide rail 19 of the side plate 17, the elbow portion 20 of the L-shaped lid 9 is prevented from protruding outward. In some cases, the elongated hole 13 can be curved and the guide rail 19 can have a linear shape.

Alternatively, both the elongated hole 13 and the guide rail 19 may be curved, and in this case, by devising the shapes of the elongated hole 13 and the guide rail 19, the L-shaped lid 9 may be formed. It is also possible to control the trajectory of the tip of the first plate portion 15 of the L-shaped lid 9 accompanying the rotation of the.

Further, in the above embodiment, the elongated hole 13 penetrating the inner wall 11 of the recess 8 is formed in the side plate 17 of the L-shaped lid 9.
A guide rail 19 is provided on each of the
Although the guide projection 12 is guided, the present invention is not limited to this, and a guide rail may be provided on the inner wall 11 and an elongated hole penetrating the side plate 17 may be provided, or Both the inner wall 11 and the side plate 17 may be configured by providing guide rails or elongated holes penetrating therethrough.
