Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device system in which a power indicator provided in an electronic device for a system is easy to see.

[0002]

2. Description of the Related Art In a conventional vehicle-mounted electronic device system, a plurality of system electronic devices a are integrated by using a mounting bracket b as shown in FIG. 8, and an automobile as shown in FIG. A method of fixing and using in the trunk d of c is generally adopted.

[0003]

In the conventional system electronic equipment a, a display lamp e such as a power supply indicator for displaying an operating state is provided for each electronic equipment a, and a power switch (not shown) is turned on. Then, although it is turned on, when it is installed in the trunk d of the automobile c using the mounting bracket b, the connection cords f wired to each electronic device a interfere with the display lamp e. Is difficult to see, and since the display lamp e is located on the side surface, it is difficult to see.

In order to improve the appearance, connection cords f
9 (2) may be covered from above by a board g or the like as shown in FIG. 9 (2), but in this case the display lamp e cannot be seen from the outside at all, and there is a problem that the operating state cannot be confirmed.

The present invention has been made in order to solve such a problem, and an electronic equipment system in which a blinking state of a display lamp of an electronic equipment for a system mounted on an electronic equipment rack can be easily confirmed from the outside. It is intended to provide.

[0006]

In order to achieve the above object, the present invention provides an electronic device having a display lamp on a surface other than a surface from which a connection cord is drawn out, and a light from the display lamp of the electronic device on the upper surface thereof. Has a display section for guiding light,
Further, it is characterized by comprising an electronic device rack for accommodating the electronic device and a light guide member for guiding light from a display lamp of the electronic device to the display section. Further, the electronic device rack is provided in an outer case of another electronic device.

[0007]

With the above structure, even if the electronic device system is installed in the trunk of an automobile, the operating state of the electronic device can be confirmed only by looking at the display section on the top surface of the rack for electronic devices, which is very easy to see.

And a mounting hole 9 for mounting the mounting screws 10 for fixing the electronic devices 1 to 4 to the outer rack 5 are formed on the opposite side surface. ing.

As shown in (3) of FIG. 1, the exterior rack 5 has the same number of display units 5a to 5d as the electronic devices 1 to 4 housed on the upper surface thereof, which are linearly opened in the front-rear direction, and both sides thereof are open. A plurality of mounting holes 11 for inserting the mounting screws 10 are formed in the surface for each of the electronic devices 1 to 4.

On the other hand, the light guide member 8 is, as shown in FIG. 2A, the electronic equipments 1 to 4 housed in the exterior rack 5.
There is an integral type that is attached to one of the above, and a single type that is attached to each of the electronic devices 1 to 4 as shown in (2) of FIG. 2, and any one may be used.

The integrated type light guide member 8 shown in FIG. 2A is integrally formed of a resin having a light guiding property, and has a continuous portion 8a in the horizontal direction, and the continuous portion 8a. Has a mounting hole 8c for mounting the electronic device 1 at one end thereof, and a plurality of light guides in the same direction as the display portions 5a to 5d opened in the outer rack 5 in the direction orthogonal to the connecting portion 8a. The portion 8b is formed.

Two of the light guide portions 8b are short and the other two are long, and the lower end of the short light guide portion 8b is an electronic device housed in the exterior rack 5 so that it is on the upper side. As shown in FIG. 3, the light emitted from the display lamp 7 is transmitted through the light guide portion 8b to the exterior rack 5 as shown in FIG. It is adapted to lead to the display portions 5a and 5b on the upper surface. The lower end of the long light guide 8b reaches the vicinity of the display lamp 7 of the electronic device 3, 4 housed in the exterior rack 5 so that the lower end is c-plane cut 8d. The light emitted from the display lamp 7 to the light guide portion 8b.
It is designed to be guided to the display portions 5c, 5d on the upper surface of the exterior rack 5 via.

The single light guide member 8 shown in FIG.
In this case, the continuous portion 8a is not provided, and the mounting hole 8c is formed for each light guide member 8b, and the light guide member 8 is mounted on each of the electronic devices 1 to 4 for use.

Next, the operation will be described. When mounting the system electronic devices 1 to 4, the light guide member 8 is first attached to one of the electronic devices 1 to 4 housed in the exterior rack 5 as shown in FIG. 1) and then attach each electronic device 1 to 4 so that the light guide member 8 is located between the electronic devices 1 and 3 and 2 and 4 as shown in FIG. 4B. The electronic devices 1 to 4 are housed in the external rack 5, and the mounting screws 10 are screwed from both sides of the external rack 5 to fix the electronic devices 1 to 4 to the external rack 5.

In this state, each light guide portion 8b of the light guide member 8 is
As shown in (3) of FIG. 4, the lower end of each electronic device 1 to 4
Since the c-plane cut 8d portion faces the display lamp 7 of the display lamp 7, the display portion 5a on the upper surface of the outer rack 5 is guided by the light guide portion 8b emitted from each display lamp 7.
Through 5d.

As a result, even if the exterior rack 5 is installed in the trunk of an automobile or the like, the display portion 5a is provided on the top surface of the exterior rack 5.
5d to 5d, the blinking state of the display lamp 7 of each of the electronic devices 1 to 4 can be easily confirmed. A lens or a transparent plate may be fitted to the display portions 5a to 5d on the upper surface of the exterior rack 5.

On the other hand, FIG. 5 shows one case of the electronic devices 1 to 4.
In this embodiment, the case 1a also serves as an exterior rack. The case 1a is formed of a heat radiating plate, and a plurality of electronic devices 2 to 4 can be accommodated in the case 1a.

Also in this case, the display unit 5 is provided on the upper surface of the case 1a.
By providing a to 5d, the light guide member 8 guides the light emitted from the display lamp 7 of each of the electronic devices 1 to 4 to the display portions 5a to 5d. Further, the positions of the display units 5a to 5d for guiding the light emitted from the display lamp 7 of the one electronic device which also serves as the exterior rack may be provided at other positions.

Further, FIG. 6 shows electronic devices 1, which are arranged one above the other.
In the embodiment of the light guide member 8 in the case where the display lamp 7 is located at the same position on the side surfaces of 3 and 2, 4, the short light guide portions 8b and the long light guide portions 8b are alternately provided to change the length. By bending the long light guide portion 8b toward the display lamp 7 side of the lower electronic devices 3 and 4, the light guide portion 8b is prevented from interfering. In this case, a single unit may be used as shown in FIG.

Further, in the above embodiment, the display portions 5a to 5d are provided on the upper surface of the exterior rack 5 in a straight line, but they may be provided in two rows as shown in FIG. 7 and the light guide member 8 is partitioned. It may be provided as a plate in the exterior rack 5 in advance.
