The instrument device which is the best embodiment of the present invention will be described with reference to FIGS. The instrument device 1 is attached to an instrument panel of a vehicle. As shown in FIG. 1, the instrument device 1 indicates an engine speed on a speed display plate 11 and indicates a vehicle speed on a speed display plate 12. It is possible. A travel distance display board 13 positioned below the speed display board 12 indicates a travel distance. Each display board 11-13 consists of EL elements. One of the features of the instrument device 1 of the present invention is that the display surface of the rotational speed display plate 11 and the display surface of the speed display plate 12 have a step difference before and after the driver, and each measurement displayed on these steps is displayed. The display of values is three-dimensional.

a. More specifically, the configuration of the instrument device 1 will be described. In the instrument device 1, as shown in FIGS. 2 (a) and 2 (b), the facing plate 3 and the front glass 4 are sequentially stacked from the front side of the case 2. The HPC (hard printed wiring board) 5 and the cover 6 are superposed in order from the back side of the case 2, and these are integrally attached to the case 2.

  The case 2 is molded from a synthetic resin, and a protrusion 21 protrudes from the flat base 20 of the case 2 toward the front as viewed from the driver. The upper surface of the protrusion 21 is formed in a semicircular arc shape. The facing plate 3 has a stepped portion 31 into which the protruding portion 21 is fitted, and the display plates 11 to 13 are sandwiched between the case 2 and fixed. Further, the facing plate 3 shields the driver from the portions other than the display portions of the measurement values of the display plates 11 to 13.

  The front glass 4 protects the inside of the instrument device 1 by preventing the intrusion of dust into the instrument device 1 and the contact with fingers. On the HPC 5, a display device for displaying each measurement value on each display board 11 to 13, a control circuit for electronically controlling blinking of a direction indicator, generation of a notification sound, and the like are mounted. Connectors for connection to the plates 11 to 13 are provided. The cover 6 is made of synthetic resin like the case 2 and protects the inside of the instrument device 1, particularly the HPC 5 from the back.

  The structure for holding the display plates 11 to 13 by the case 2 will be described in more detail. On the upper surface of the base 20 of the case 2, a rotation number display plate holding portion 2 a is provided on the upper surface of the base 20. A dent portion is formed in accordance with the shape. Further, a concave portion matching the shape of the semicircular arc-shaped speed display plate 12 is formed on the upper surface of the protruding portion 21 of the case 2 as the speed display plate holding portion 21a. Further, a recessed portion that matches the shape of the rectangular travel distance display plate 13 is formed as a travel distance display plate holding portion 2b at a position on the base 20 that is inside the protruding portion 21 (speed display plate 12). Yes.

  Then, the rotation speed display plate 11 is fitted into the rotation speed display plate holding portion 2a, and the movement of the edge of the rotation speed display plate 11 is restricted by the turn-back plate 3 stacked from above. Similar to the rotation speed display board 11, the speed display board 12 and the travel distance display board 13 are also fitted into the speed display board holding part 21a and the travel distance display board holding part 2b, respectively.

b. In the instrument device 1 having these configurations, (1) as shown in FIG. 3, the rotation speed display plate 11 is positioned on one plane 2 c including the upper surface of the base portion 20, and the speed display plate 12 is Located on another plane 2d including the upper surface. The one plane 2c and the other plane 2d are substantially parallel, and these two planes 2c and 2d are arranged so that the height of the protruding portion 21 is substantially in the direction of the driver's line of sight with the other plane 2d facing forward. Has a minute interval. From the driver, the display of the vehicle speed on the speed display board 12 appears to rise to the near side from the display of the engine speed on the speed display board 11 and the display of the travel distance on the travel distance display board 13. That is, a novel three-dimensional effect such as a three-dimensional display of the vehicle speed, the engine speed, and the travel distance is provided to the driver.

  Further, (2) the housing space shown in FIG. 3 is provided between the one flat surface 2 c including the rotation speed display plate 11 and the other flat surface 2 d including the speed display plate 12 inside the protruding portion 21. A is formed. The shape of the accommodation space A is defined by the shape of the protruding portion 21. Here, the cross section of the accommodation space A has a shape of a semicircular arc having a width, and the accommodation space A is The cross section is a space that is continuous in a columnar shape in a direction perpendicular to the HPC 5.

  Conventionally, electrical and electronic parts having heights such as a relay for blinking a direction indicator or the like, a buzzer for generating a notification sound, and the like are usually arranged on the back surface of the HPC. It is possible to accommodate the electrical and electronic parts 5a and 5b having such heights as the relay and the buzzer in the accommodation space A described above. By effectively using the accommodation space A in this way, it is possible to make the entire instrument device compact and to increase the degree of freedom of layout of electric and electronic components on the HPC. The entire instrument device can be made thinner by matching the height of the protruding portion with the largest electric / electronic component mounted on the HPC.

  In contrast to the above-described instrument device 1, in the instrument device 31 of the comparative example shown in FIG. 4, a step is provided between a rotational speed display plate 41 that displays the engine rotational speed and a speed display plate 42 that displays the vehicle speed. Not. The instrument device 31 of FIG. 4 is in a state in which the front glass and the facing plate are removed, but the three-dimensional effect is poor with respect to the display of the engine speed and the vehicle speed, and the thickness is overall, (1) The superiority of the instrument device 1 having the effect (2) is confirmed.

(Other embodiments, etc.)
As mentioned above, although this invention was demonstrated by specific embodiment, this invention is not limited to the said embodiment. The present invention can be implemented by changing the above-described embodiment without departing from the scope of the invention.
a. For example, in the rotation speed display board 11 and the speed display board 12 of the above-described embodiment, each measurement value is indicated by representing a pointer by a picture or lighting a plurality of indicators according to a numerical value. I assumed that. Unlike this, the instrument device disclosed in Japanese Patent Laid-Open No. 2005-338059, the instrument device disclosed in Japanese Patent Laid-Open No. 2004-132756, and the like, the measured value is indicated using a mechanically rotating pointer body. It may be. In this case, the rotation speed display board 11 and the speed display board 12 each provided with each scale plate for representing each measurement value are provided in the rotation speed display board holding part 2a and the speed display board holding part 21a, and the rotation surface on the scale board. Then, rotate each pointer.

b. The travel distance display board 13 is attached on the case 2 and is placed on the same plane 2c as the rotation speed display board 11 (FIGS. 2 and 3). Unlike this, the travel distance display board may be held on a different plane from the rotation speed display board and the speed display board.
For example, in the instrument device 51, as shown in FIG. 5, the travel distance display plate 63 is positioned between a plane 52 a including the rotation speed display plate 61 and a plane 52 b that serves as a reference for the position of the speed display plate 62. And provided on a plane 52c that is parallel to the plane 52a and the plane 52b.

That is, on the case 52 of the instrument device 51, there is provided a rotation speed display plate holding portion 71 a for holding the rotation speed display plate 61, and a protruding portion 71 protruding from the upper surface of the case 52 in two stages is provided.

The accommodation space B formed here is secured larger than the accommodation space A (FIG. 3) of the instrument device 1 by a space obtained by moving the lower surface 71 c upward from the upper surface of the case 52. That is why. In addition, since the three measurement values are three-dimensionally displayed at positions with different depths as viewed from the driver, the three-dimensional effect is increased.

c. As shown in FIG. 5, the surface 71b on the upper side of the protrusion 71 is formed in a mortar shape, and the speed display plate 62 is formed in accordance with the shape of the surface 71b on the upper side. An effect can be obtained.

d. Furthermore, the image display board provided with a step between a plurality of sheets is not limited to the one that displays the engine speed, the vehicle speed, or the travel distance, and the shape thereof may take various forms. FIG. 6 shows an example instrument device 80. That is, no dial plate is used in the instrument device 80, and the image display board 81 represents various states of the vehicle. The image display board 82 and the image display board 83 constitute a speedometer, and the image display board 82 is a scale. The image display board 83 lights a plurality of indicators arranged in a semicircular arc on the scale of the image display board 82 in accordance with the vehicle speed. The image display board 84 represents a travel distance or the like. The image display board 85 represents the fuel amount, and the image display board 86 represents the water temperature.

  Here, the image display board 83 is formed in a mortar shape. In particular, it is also possible to display the hands and characters as a 3D image on the image display boards 82, 85, 86, and the like. In this case, the 3D image can be projected more realistically than the instrument device 31 of FIG. 4 by the image display boards 81 to 86 having steps on the front and rear sides.

e. The HPC 5 is assumed to be slightly smaller than the case 2 as shown in FIG. In contrast, the HPC may be smaller and fit inside the protruding portion of the case. Here, (1) As shown in b above, the projecting part is projected in two stages, or (2) the revolution number display plate is formed in a disk shape, and the projecting part is formed in a cylindrical shape according to this. By doing so, it is possible to secure an accommodation space of a size necessary for accommodating electrical and electronic parts on the HPC.
