[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting structure for an electronic device housing door, and more particularly to an electronic device housing door lighting structure that can be easily opened and closed even in a dark place.

[0002]

2. Description of the Related Art An external unlocking operating device used for an intercom at an entrance incorporating an electric lock is housed in a housing having a door and is installed in parallel with the intercom at the entrance. To unlock the electric lock outside the entrance, open the door of the case and enter the password from the button on the unlocking device.

Conventionally, in this external unlocking operating device for an electric lock, as shown in FIGS. 2 (a) and 2 (b), an operating button B'as an electronic device operating portion is housed in a housing 2 '. The door 1'which protects the operation button B'is configured with a cutout 3'at the bottom as a finger-holding portion for opening and closing. When operating the button of the unlocking operating device M'as an electronic device, put a finger into the finger-holding part 3'and rotate the door 1'to open it, and preset to 5 operation buttons B '. Enter the pattern.

[0004]

However, in the above-mentioned conventional external unlocking operating device M'of the electric lock, there is no illumination mechanism for the casing door, and the casing door is opened and closed when the surroundings become dark. It was done in.

[0005]

[Objective] The present invention has been made in order to solve the above-mentioned conventional drawbacks, and is a clue for opening and closing a door even in the dark, in an electronic device housing that is installed in a dark place and opens the door before operating the operation buttons. An object of the present invention is to provide an illumination structure for an electronic equipment housing door whose location can be visually confirmed.

[0006]

In order to achieve the above object, an illumination structure for an electronic equipment housing door according to the present invention has an electronic equipment operating portion housed in a housing provided with the door and a cutout in the door. The electronic device operation section is formed of a transparent member having a built-in light source, and the inner surface facing the notch of the housing is formed as a concave curved surface.

[0007]

According to the lighting structure of the electronic device housing door of the present invention,
Equipped with a light source and an operation button composed of a transparent member,
The housing door has a notch that serves as a clue when opening and closing, and the inner surface of the housing facing the notch is a concave curved surface, so the light from the light source built into the operation button It reflects and reaches the outside from the notch, and even when it is dark it is possible to visually confirm the clue when opening and closing the door.

[0008]

[Embodiment] An embodiment of an illumination structure for an electronic equipment housing door according to the present invention will be described below with reference to an example of an external unlocking operating device used as an electronic equipment housing with an electric lock incorporated in a front doorphone. Will be described in detail with reference to the drawings. The external unlocking operating device is housed in a housing having a door and is installed side by side with an intercom at the entrance. To unlock the electric lock outside the entrance, open the door of the case and enter the password from the operation button of the unlocking operation device.

As shown in FIGS. 1 (a) and 1 (b), the external unlocking operating device M protects the operating button B with a housing 2 which houses an operating button B as an electronic device operating portion. Door 1
The door 1 is provided with a notch 3 at its lower portion as a finger-holding portion for cueing at the time of opening and closing. The operation button B is composed of a transparent member containing the light source L, and the lower inner surface 4 of the housing 2 facing the notch 3 is formed into a concave curved surface and is coated with a paint having high reflectance.

When the surroundings of the external unlocking operating device M is dark, the light source L incorporated in the operation button B is turned on automatically based on a preset illuminance or manually from inside the room. The light of the light source L built in the transparent operation button B is emitted from the operation button B in all directions, and in particular, the lower inner surface 4 of the housing 2 formed with a concave curved surface and coated with a highly reflective paint.
Then, the light is reflected as shown by the arrow in FIG. 1A, and goes out as light La from the notch 3 in the lower portion of the door 1. Even if the surroundings of the external unlocking operation device M is dark, the light La reveals the notch 3 as the finger hook.

When operating the buttons of the unlocking operating device M, a finger is put into the finger-holding portion 3, the door 1 is rotated and opened, and a preset pattern is input to the five operation buttons B. As an example of an external unlocking operating device used for door intercoms that incorporates an electric lock as an electronic device housing, it has been explained as an example, but it is installed in a dark place and the door is opened before operating the operation buttons. It is also suitable for the electronic device housing.

[0012]

As is apparent from the above embodiments, the lighting structure of the electronic device housing door according to the present invention accommodates the electronic device operating portion in the housing provided with the door and provides the notch in the door. Since the electronic device operating section is made of a transparent member containing a light source, and the inner surface facing the notch of the housing is formed as a concave curved surface,
In an electronic device housing installed in a dark place where the door is opened before operating the electronic device operating section, it is possible to visually confirm the cue point when opening and closing the door even in the dark.
