Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a panel illumination switching device, and more particularly to a panel illumination switching device suitable for simplifying the panel structure without having many light sources.

[0002]

[Prior art]

 As for conventional panel illumination switching, even in models where the panel can be attached and detached as shown in Fig. 4, the illumination switching of various indicators is done electrically by installing a two-color LED or two-color illumination knob 12 etc. It was supposed to be switched.

[0003]

[Problems to be solved by the device]

 However, the conventional panel illumination switching structure requires as many LEDs and lamps as the number of colors that can change the emission color, resulting in high cost. The problem of heat in the lamps and the light guide plate that houses many lamps are thick. However, there is a drawback that unevenness in light is likely to occur and the structure of the panel is complicated.

The present invention has been made in view of the above points, and an object thereof is to solve the drawbacks of the conventional example and to filter a plurality of colors capable of moving the light from the light source provided in the device body. There is provided a panel illumination switching device which is configured to be guided to the index of the panel through the light guide plate.

[0005]

[Means for Solving the Problems]

 The panel illumination switching device of the present invention is a panel that can be attached to and detached from a device body such as an in-vehicle audio device and illuminates various indicators by a light source provided in the device body. A movable filter of at least two colors and a light guide plate for guiding the light passing through the filter to the index are provided, and the color emitted from the index of the panel can be changed by switching the filter. Is.

[0006]

[Action]

 According to the present invention, in a panel which is detachably attached to a device body such as an in-vehicle audio device and which illuminates various indicators with a light source provided in the device body, at least two or more colors are moved to an outlet portion for supplying light of the device body. It is possible to change the color of light emitted from the index of the panel by providing a filter and a light guide plate that guides the light passing through the filter to the index. A light source of the number of colors is not required, and it is not necessary to attach a switch for switching the color of illumination light to the panel, the panel structure can be simply configured, and problems such as uneven light can be solved.

【Example】

 An embodiment of the panel illumination switching device according to the present invention will be described with reference to FIGS.

FIG. 1 is a front view showing an embodiment of the present invention, FIG. 2 is a front view of an apparatus main body showing a state in which a panel is removed, and FIG. 3 is a partial cross-sectional view of a removable panel seen from the upper surface.

In the figure, 1 is a panel body, 2 is a removable panel, 3 is an escutcheon, 4 is an extrusion button, 5 is a plate, 6 is a filter (A), 7 is a filter (B), 8 is a lamp, and 9 is a lamp. Is a light guide plate, 10 is a printed circuit board, 11 is a knob, and 12 is a connector.

As for the structure of the panel, when viewed from the front of the device body, the upper half is a fixed panel composed of a cassette insertion slot and a display section for displaying information such as frequency and other information, and the lower half is a knob with illumination or the like. The detachable panel 2 is a detachable panel 2 with the attached operation unit.

When the detachable panel 2 is pushed out from the main body of the equipment and the bodan 4 is pushed and removed, the filter (A) 6 and the filter (B) attached to the plate 5 are attached to the detached panel 2 as shown in FIG. 7 is arranged at a position facing the lamp 8 provided on the main body of the device, and the filters (A) 6 and (B) 7 can be slid to the left and right with fingers.

Further, a connector 12 for connecting the switches of the detachable panel 2 and a circuit in the device body is provided in a portion where the detachable panel 2 is removed, and the connector 12 attached to the detachable panel 2 side is detachable. It is designed to be connected when the panel 2 is attached.

On the other hand, the structure of the detachable panel 2 is such that when the detachable panel 2 is attached to the main body of the device, the cross section of the lamp 8 and the lamp 8 face each other via the filter (A) 6 or the filter (B) 7. The light guide plate 9 is attached, and the light guide plate 9 is bent at a right angle at the center of the detachable panel 2 in the thickness direction and is parallel to the printed circuit board 10 provided in the detachable panel 2. It is arranged in the longitudinal direction.

The printed circuit board 10 in the detachable panel 2 is mounted with switches which are operated via a shaft of a knob 11 arranged on the front surface of the detachable panel 2, and the shaft of the knob 11 has a light guiding function. The above material reaches the printed circuit board 10 through the light guide plate 9.

The lamp 8 of the device body is turned on when the removable panel 2 is attached to the device body, and is turned off when it is removed.

Therefore, when the detachable panel 2 configured as described above is attached to the main body of the device, the lamp 8 lights up, so that light passes through the filter (A) 6 or the filter (B) 7. The light having the color of the filter is guided by the light guide plate 9 and illuminates the knob 11 itself through the axis of the knob 11.

In this way, when it is desired to change the illumination color of the knob 11, the detachable panel 2 is removed and the filter (A) 6 and the filter (B) 7 are slid with a finger so that the color of light passing through the light guide plate 9 is changed. You can change the illumination color of Knob 11.

In this embodiment, the filters are two colors (A) and (B), but it is possible to illuminate many colors by increasing the colors of the filters to be slid.

[0019]

[Effect of the device]

 Since the panel illumination switching device according to the present invention is configured as described above, it has the following effects.

Since the light source is housed in the main body of the device and is guided to the panel-side knob by the light guide plate through the filter, it is possible to switch multiple knobs to multi-color illumination with one light source. Therefore, it is not necessary to provide a special changeover switch for changing the illumination color on the detachable panel, resulting in cost reduction and space saving.

Moreover, it has excellent features such as a simple structure inside the removable panel and a thin finish.
