By fixing the dial plate 17 for transmitted illumination as described above, the shape of the surface of the transmitted illumination instrument can be easily reduced in size, and an instrument structure advantageous as an instrument main body used for distant display is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a black face meter used in a vehicle, and more particularly to a meter structure suitable for displaying the meter display far from a driver's seat by using a lens.

[0002]

[Prior Art]

 The display surface of the instrument built into the instrument panel is generally a short distance from the driver's eye point, so the amount of eye movement when looking at the instrument display surface is large during driving. In particular, when driving at high speeds, it may be difficult to see the instrument display and the danger of driving.

Therefore, in order to make the display of the instrument easy to see during operation, a lens is arranged in the opening of the instrument panel, and a self-luminous instrument main body is installed in the back of this lens. By seeing the light emission display of the instrument through the lens, the display of the instrument body is displayed as a virtual image by the lens and is displayed further rearward than the position of the instrument body. Therefore, the visibility of the display by the driver is improved.

Since the instrument main body used for the distance display is enlarged and displayed according to the magnification of the lens, at least the display surface of the instrument main body is small, or the instrument panel has a small size. It is required that the instrument body incorporated inside should be small in order to avoid interference with other objects.

[0005]

[Problems to be solved by the device]

 However, the conventional transillumination type (self-luminous type) automotive instrument body structure is as shown in FIG. That is, the instrument movement 2 is incorporated in a cylindrical housing 1 with both ends open, the printed circuit board 3 is attached to one opening of the housing 1, and the transillumination dial 4 is attached to the other opening. Further, a light guide plate 6 and a light source 7 for transmitting and illuminating a scale or the like 5 provided on the surface of the dial 4 are arranged on the back surface of the transillumination dial 4. Reference numeral 8 denotes a pointer fixed to the pointer shaft 9 expended from the movement 2.

In the conventional instrument main body having such a configuration, if the shape is constant, there is no problem, but since the instrument main body is used as a distance display instrument, its transmission display surface should be miniaturized. For example, even if the position of the scale 5 is changed to the position of 5'shown by the chain line, and the length of the pointer 8 is shortened to 8 ', the light from the light source 7 is blocked by the cylindrical housing 1. The transmitted illumination of the scale 5'was not expected.

That is, in the conventional example, since the light source and the light guide means are provided outside the cylindrical housing 1 that supports the transillumination type dial, if the display surface of the instrument is designed to be small, There was a problem in that the light for doing so was blocked by the cylindrical housing, making transmitted illumination impossible.

[0008]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned conventional problems, in which an instrument movement and a lighting means are assembled inside a substantially cylindrical housing, and the tubular housing is further provided with By fixing the dial for transillumination that has a transillumination scale inside the opening edge, the shape of the surface of the transillumination instrument can be easily reduced, and it can be used as a main unit for distance display. It is to provide an advantageous instrument structure.

【Example】

 The present invention will be described in detail below based on the embodiments shown in the drawings.

In FIGS. 2 and 3, reference numeral 11 denotes a substantially bowl-shaped housing, and an instrument movement 12 is fixed to a central portion of the housing 11 by a stopper 13 and a mounting screw 14. Further, the connection terminal 15 of the movement 12 is connected to the circuit of the printed board 16 by soldering. A transillumination dial 17 is fixed to the peripheral edge of the opening of the housing 11 by a mounting screw 18. The transmissive display scale 19 provided on the transillumination dial 17 has an open peripheral edge of the housing 11. It is formed so as to be located inside the portion. Reference numeral 20 is a light-shielding layer, 21 is a pointer fixed to the tip of a pointer shaft 22 expended by the movement 12, and 23 is a circular fluorescent lamp located inside the housing 11 and around the movement 12. The fluorescent lamp 23 is fixed to the housing 11 by appropriate fixing means. Reference numeral 24 indicates a front cover.

As described above, in the present embodiment, the instrument movement 12 is fixed to the center of the inside of the substantially bowl-shaped housing 11, and the light source 23 is arranged around the movement 12. Since the inside of the housing 11 is fully illuminated without being shielded by other objects, all the transillumination display portions located inside the opening edge of the housing 11 are effectively displayed.

Therefore, if it is inside the opening edge of the housing 11, the shape of the display portion on the display surface of the instrument main body can be arbitrarily reduced, and the practicality as a distant display instrument is enhanced.

Although the circular fluorescent lamp is used as the light source in the above embodiment, the present invention is not limited to this, and one or a plurality of miniature balls may be used, for example.

[0014]

[Effect of the device]

 As described above, according to the present invention, the instrument movement 12 and the illumination lamp 23 around the instrument movement 12 are arranged and fixed at the center of the inside of the substantially tubular housing 11, and the tubular housing 11 is fixed. According to this, the transmitted illumination dial plate 17 has the instrument structure in which the transmitted illumination dial plate 17 provided with the transmitted illumination scale 19 inside the opening peripheral edge is fixed. Since the illumination light is transmitted inside the opening edge of the cylindrical housing 11, the display surface of the instrument can be reduced within the range inside the opening edge of the cylindrical housing, and in particular, a reflective display is performed using a lens. The effect that it can be effectively used as a remote display instrument is obtained.
