Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the structure of a nose, and in particular, a nose for an on-vehicle tuner.

[Conventional technology]

Conventionally, as a nose for a vehicle-mounted tuner, a structure in which operation knobs are fitted into window holes arranged in a row on a panel plate is known, and in the vicinity of each operation knob,
Normally, a display indicating the function is provided above, and a display is also provided on the operation knob itself. It is said that these displays can be confirmed by being illuminated at night, but generally, a lamp arranged on the back side of the display is used to obtain this illumination through a lens,
The structure is such that a translucent member is arranged, the end face of the translucent member is illuminated, and the light that has passed through the translucent member brightens the display.

[Problems to be solved by the device]

However, according to this conventional nose structure, there is a problem that the sharpness of the display illuminated by the distance from the light source becomes uneven.

The present invention has been made by paying attention to the problems of the related art, and provides a nose structure that solves the problems and can obtain uniform sharpness without unevenness. It is an object.

[Means for Solving the Problems]

In order to achieve this object, the audio device according to the present invention comprises:
A first light-transmissive member mounted on the back surface of the function display portion of the operation knob, an operation knob pressing member stacked on the first light-transmissive member, and an operation knob pressing member stacked on the knob pressing member, A second light-transmissive member corresponding to the display portion, and a light source accommodating member that regulates the illumination direction of the light source provided on the end faces of the first and second light-transmissive members, and The translucent member is characterized by being provided with a nose that is illuminated by a different light source for each system.

[Action]

With the above-described configuration, since different light sources are used depending on the positional system of the display unit, the display unit is illuminated with uniform and uniform definition.
