Conventionally, for example, air conditioner display devices and internal/external air control devices installed in vehicles such as automobiles use transparent light guide plates such as acrylic resin to guide light from a light source to a surface panel (display board) or operation knob. Vehicles that are brightly illuminated to improve visibility, operability, and interior design at night are widely used. Figure 1a,
b shows an example of a display device incorporated in a conventional air conditioner display device. To explain this with reference to the figure, 1 is an air conditioner display device, 2 is attached to the front of the air conditioner display device 1 and displays characters, symbols, etc. A display board 5 having a light shielding film 4 applied to a portion other than the display portion 3
is a lever operation hole provided in the display board 2; 6 is a knob shaft slidably inserted into the lever operation hole 5; 7 is an operation knob attached to the knob shaft 6 via a light guide lever 8; 9 is a light guide plate disposed on the back surface of the display board 2; 10 is a light source; 11 is the light guide plate 9;
It shows a case body that houses a light source 10 and the like, and guides light 12 from the light source 10 to the display panel 2 via the light guide plate 9 and illuminates the display section 3. At the same time, the light guide lever 8
to illuminate the surface of the operating knob 7. For this reason, the tip of the light guide lever 8 is exposed on the surface of the operating knob 7 and is formed into a rough surface by frosting or texturing, thereby scattering and reflecting light and improving the visibility of the operating knob 7. ing. Further, the rear end surface of the light guide lever 8 is cut off diagonally to form a reflective surface 13.

However, in such a conventional display device, a portion of the light 12 emitted from the light guide plate 9 leaks to the outside from the lever operation hole 5, resulting in illumination of the lever operation hole 5 itself, and the inside of the case body 11. Not only is it visible through the lever operation hole 5, but if the lever operation hole 5 is bright, the illumination effect on the operation knob 7 is relatively reduced, which has a negative effect on visibility.

生じ、ここから漏光するという欠点があつた。 Therefore, as a means to solve such problems, for example, Japanese Utility Model Publication No. 33-12447, Publication of Utility Model Application Publication No. 48-8656, etc.
As seen in Japanese Patent Application Publication No. 2003-11000, there is a known device in which the lever operation hole is covered with a flexible light-shielding member to prevent internal light from leaking to the outside. However, these light shielding members are simply attached to the back of the display board, so if used for a long period of time, the light shielding member itself may stretch or the adhesive may peel off.
A gap was formed between the peripheral edge of the lever operation hole and the light shielding member, and there was a drawback that light leaked through the gap.

In order to achieve the above object, the present invention provides an operating knob at the tip of a knob shaft that passes through a lever operating hole provided in a display board and is movable along the longitudinal direction of the hole. In a display device that illuminates the knob by guiding light from a light source to a distal end surface, the lever operation hole is covered with a flexible light-shielding member, and the light-shielding member has a peripheral portion that covers the entire circumference of the display. It has a slit which is held between the plate and the case body and is long in the longitudinal direction of the operation hole, and the knob shaft is made to protrude outside through this slit.

FIG. 4 is a sectional view taken along the line of FIG. 3. Components in the figure that are the same as those in FIG. 1 are designated by the same reference numerals, and their explanations will be omitted. In these figures, the lever operation hole 5 has a rim 2 on its periphery.
0 is fitted and fixed, and is covered by a light shielding member 21. The light shielding member 21 is formed of a flexible opaque film such as a urethane sheet or polyester, felt, a rubber sheet, etc., and its peripheral portion is sandwiched between the display board 2 and the case body 11 over the entire circumference. A slit 22 extending long in the longitudinal direction of the lever operation hole 5 is formed in the center, and a knob shaft 6 and a light guide lever 8 project from the slit 22 to the front of the display panel 2.
In this case, the knob shaft 6 and the light guide lever 8 have a rectangular cross-sectional shape and arcuate ends at both ends to reduce resistance to the light shielding member 21 and prevent wear. However, the cross-sectional shape is not limited to this and may be a rhombus.

を防止し、漏光防止効果大である。 According to the display device having the above configuration, the light shielding member 21 prevents the light 12 from the light source 10 from leaking from the lever operation hole 5, so that the entire lever operation hole 5 is not brightly illuminated. ,
Therefore, the position of the operation knob 7 can be easily confirmed. Further, since the inside of the case body 11 is not visible through the lever operation hole 5, the appearance of the display device itself is not impaired. Furthermore, the light shielding member 21 has sufficient flexibility and can be freely bent, so that the operating knob 7
When the knob shaft 6 and the light guide lever 8 are moved, there is no large resistance to the knob shaft 6 and the light guide lever 8, and good operability can be maintained. Moreover, since the light shielding member 21 is sandwiched by the display panel 2 and the case body 11 at its peripheral edge, there is no need to worry about stretching or separation of the adhesive, and the light shielding member 21 can withstand long-term use.
This prevents a gap from forming between the peripheral edge of the light shielding member 21 and the light shielding member 21, and is highly effective in preventing light leakage.

As explained above, the display device according to the present invention guides light from a light source to an operation knob through a light guide plate and illuminates the knob, and the peripheral part is surrounded by the display plate and the case body. The lever operation hole is covered with a light shielding member made of a flexible material held together, and the knob shaft is made to protrude to the outside through a slit provided in the light shielding member, so that the light from the light guide plate is transmitted from the lever operation hole to the outside. Since the structure is configured so that no leakage occurs, only the operation knob can be well illuminated, and the visibility of the knob at night can be further improved. In addition, the structure is simple and inexpensive, and the external appearance is good so that the operability of the operating knob is not degraded.Furthermore, since the light shielding member is sandwiched between the display board and the case body, there is less stretching of the light shielding member. Furthermore, there is no need to worry about the adhesive peeling off, it has excellent durability, and a good light shielding effect can be obtained, so its practical effects are very large.
