FIG. 6 is an exploded view of an example of this type of vehicle display device. A storage case 1 includes a left and right movement 2 of a speedometer, a light source 3 for illumination thereof, a movement 4 of a tachometer and illumination thereof. And first and second chambers 1a and 1b, respectively, for accommodating the light source 5 for use. The illumination light sources 3 and 5 are both circular cold cathode tubes (CC).
T). The storage case 1 is also arranged between the first and second chambers 1a and 1b in a direction orthogonal to the arrangement direction of the movements 2 and 4, and accommodates a position display light source (not shown) of the torque converter. It has a third chamber 1c, which is divided into a plurality of small chambers corresponding to the number of positions of the torque converter.

A dial panel 7 made of a light-transmitting light diffusing plate is arranged on the front surface of the storage case 1. On the dial panel 7, circular light-transmitting portions 7a, 7a, position display character portions 7c,
The scales, numerals, and the like provided along the circular light transmitting portions 7a, 7a are formed by character-absent printing or the like. In front of the dial panel 7 corresponding to the circular translucent portion, pointer disks 8 and 9 each having one slit 8a and 9a formed in a radial direction are arranged, and furthermore, the front surface thereof has an ignition switch turned off. In order to realize a black face where the display is not visible, the display is covered by a smoke panel 10 having an extremely small transmittance.

In this display device, when the pointer disks 8 and 9 connected to the respective movements 2 and 4 rotate, the backlights of the illumination light sources 3 and 5 are transmitted, so that the slits 8a and 9a are moved as if by hands. The speed and the engine speed are displayed by pointing the scales, numerals, etc. on the dial panel 7 which are visually recognized.

[0006] By the way, the position display of the torque converter in this display device includes a backlight dedicated to the on-position display for enabling the on-position (current position of the torque converter) and the off-position to be simultaneously identifiable. Is provided in correspondence with.

When the front surface is covered with the smoke panel 10 for black face, not only the display of the on position where the position display light source is lit can be visually recognized, but the entire position display of the torque converter is displayed. A proposal has been made so that the display can be visually recognized, and the ON position can be visually recognized as a display with higher brightness than the OFF position by the transmissive illumination by turning on only the light source 6 in the small room at that position. Have been.

FIGS. 7 and 8 show the above-described proposed vehicle display device. In the figures, a first room 1a for accommodating a light source of a speedometer and a second room 1b for accommodating a light source of a tachometer are shown. The partition walls 1d and 1e with the third room 1c for accommodating the light source are provided with a gap 1f of a predetermined height at the upper end, while the partition wall 1g in each small room in the third room 1c has a dial panel 7 at the upper end. Is fitted in a slit 7d formed between the displays of the position character display section 7c.

The light from the light source 3 in the first chamber 1a reaches the lower surface of the dial panel 7 in the third chamber 1c via the gap 1f, and is reflected from the dial panel 7 or enters the dial panel 7 or the like. Thereby, the entire dial panel 7 is illuminated.

In the on-position display, only the light source 6 in a specific small room in the third room 1c is turned on, but the light of this light source 6 is transmitted to the partition wall 1 made of a light shielding material inserted in the slit 7d.
Since g prevents light from passing through the dial panel 7 to the adjacent position, only the on-position display is clearly illuminated.

With the above structure, the torque-composition display device located between the left and right speedometers and the tachometer takes in the illumination light of the light sources 3 of the left and right display devices from the gap 1f of the partition wall 1g at the time of the OFF display, and displays the ON display. In such a case, the light source 6 in the small room for the ON display is lit and displayed, so that light does not leak to the adjacent position side of the torque control display,
Visibility and display quality are sufficiently good.

Further, since the light from the light source 6 in the small room is completely blocked by the partition wall 1g inserted into the slit 7d of the dial panel 7, there is no light leakage to the adjacent position side, and further visual recognition is achieved. And display quality are improved.

[0013]

However, in the above-described conventional apparatus, when the light from the direction of the arrow in the drawing is considered, the magnitude of the incident light is different depending on each position, and is close to the light sources 3 and 5. The incident light becomes large and bright near the center of the torque composition display, and the incident light becomes small and dark at the upper and lower ends of the torque composition display far from the light sources 3 and 5. For this reason, there is a problem that the display luminance in the off state is different between the respective positions, that is, the luminance becomes uneven, and the display quality is reduced and the visibility is deteriorated.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and eliminates light unevenness in position display in a combination type vehicle display device in which a position display of a torque converter is arranged between two display devices. It is an object of the present invention to provide a vehicle display device capable of realizing high-quality and high-visibility display at low cost.
