  An object of this invention is to provide the measuring device which can raise the axial part which pivots a pointer | guide, and can improve a three-dimensional effect, without impairing an external appearance in view of the above point.

  In order to achieve the above object, the present invention provides a display board having scale parts arranged in the circumferential direction, a hole provided in the display board, a shaft part inserted through the hole part and rotatable, In an instrument device comprising an indicator provided at the upper end of the shaft portion and pointing to the scale portion, a reflective surface that reflects light is provided at least on a portion of the peripheral surface of the shaft portion that is exposed upward from the hole portion. It is characterized by that.

  According to the present invention, since the color, pattern, light, etc. of the display plate are reflected on the reflecting surface, the portion exposed from the hole of the shaft portion becomes assimilated and inconspicuous with the display plate. Therefore, the shaft portion can be made longer without impairing the appearance, and the three-dimensional effect can be improved by raising the pointer.

  A large diameter portion larger than the diameter of the hole portion is provided at a portion of the peripheral surface of the shaft portion that is exposed upward from the hole portion, and the reflection surface is provided on the peripheral surface of the large diameter portion. It is preferable that According to the present invention, the hole is hidden by the large-diameter portion, and the hole can be made inconspicuous.

  The instrument device generally includes a light source unit for maintaining visibility even at night. And when the light source part is arranged in the instrument device of the present invention so that light is irradiated from the peripheral edge of the display plate toward the shaft part side, the shadow of the part exposed from the hole part of the shaft part is It appears on the display board, and the appearance of the instrument device may be impaired, and the visibility of the instrument device may be reduced.

  Therefore, it is preferable that a light source unit for irradiating the display plate with light is provided, the display plate has light transmittance, and the light source unit irradiates light from below the display plate. According to the present invention, since the light from the light source unit is irradiated from below the display plate, it is possible to prevent the shadow of the portion exposed from the hole of the shaft portion from appearing on the display plate. In addition, since a part of the light emitted from the light source part appears to be reflected by the reflecting surface, the pointer seems to be floating in the air, and the appearance can be further improved.

  It is preferable that an annular stepped portion protruding upward is provided on the outer peripheral edge of the display panel. By making the shaft portion high, for example, when the instrument device is visually recognized from the passenger side of the automobile, the scale portion is reflected on the reflective surface, the appearance of the instrument device is impaired, and the visibility of the instrument device is increased. May decrease. According to the present invention, since the step portion is provided on the outer peripheral edge portion of the display plate, it is difficult to visually recognize the scale portion from the angle at which the scale portion is reflected on the reflective surface, and the scale portion is formed on the reflective surface. As a result, the appearance can be prevented from being impaired and the visibility can be prevented from being lowered.

  An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing an embodiment of the instrument device of the present invention, and FIG. 2 is an explanatory sectional view showing a section of the instrument device of the embodiment.

  As shown in FIGS. 1 and 2, a meter device 1 according to an embodiment of the present invention is a speedometer that is provided in a vehicle such as an automobile or a motorcycle and indicates a vehicle speed, and includes scale units 21 and 22 arranged in a circumferential direction. And a pointer 4 indicating the scale portions 21 and 22.

  The display panel 3 has a light transmitting property, a disk-shaped disk part 31 having a hole 31a formed in the center part, and an annular step part provided to protrude upward on the outer peripheral edge of the disk part 31. 32. On the upper surface of the stepped portion 32, a rod-shaped first scale portion 21 is attached with a predetermined interval in the circumferential direction. A second scale portion 22 is attached to the outer peripheral edge of the disk portion 31 at a position corresponding to the first scale portion 21 attached to the step portion 32.

  A shaft portion 5 that is rotatable by a motor (not shown) is inserted into the hole portion 31a. A pointer 4 is attached to the upper end of the shaft portion 5. The pointer 4 includes a disc-shaped cap portion 41, and the cap portion 41 is fitted to the tip of the shaft portion 5. The pointer 4 and the stepped portion 32 are set to have substantially the same height. Thereby, the position of the scale parts 21 and 22 pointed to by the pointer 4 appears to be shifted from the position of the scale parts 21 and 22 that the pointer 4 should originally point due to the height difference between the pointer 4 and the stepped part 32. Therefore, it is possible to prevent the visibility of the instrument device 1 from being lowered.

  A large-diameter portion 41a is provided on the lower surface of the cap portion 41 so as to cover a portion of the shaft portion 5 that is larger than the diameter of the hole portion 31a and exposed upward from the hole portion 31a. Thereby, the hole part 31a can be hidden behind the large diameter part 41a, and the hole part 31a can be made inconspicuous.

  The outer peripheral surface of the large-diameter portion 41a is formed as a reflective surface (mirror surface) that reflects light. Since the color, pattern, and the like of the display plate 3 are reflected on the reflection surface (mirror surface) of the large diameter portion 41a, the large diameter portion 41a and the portion exposed upward from the hole portion 31a of the shaft portion 5 are made inconspicuous. be able to. Therefore, the shaft portion 5 can be lengthened without deteriorating the appearance as compared with the conventional case, and the pointer 4 is visually recognized as if it is floating in the air, so that the stereoscopic effect can be improved.

  A substrate 6 is provided below the display panel 3 with a gap. The substrate 6 is provided with a plurality of LEDs 7 as a light source unit for irradiating the display panel 3 with light. By making this LED 7 emit light, the instrument device 1 can maintain visibility even at night.

  Further, since the shaft portion 5 is provided higher than the conventional one, when the light source portion is arranged so as to irradiate light from the peripheral edge of the display plate 3 toward the shaft portion 5 side, the large-diameter portion is formed on the display plate 3. Shadows such as 41a and cap 41 are easily captured. However, in the instrument device 1 according to the embodiment, the display board 3 has light transmittance, and the LED 7 that emits light from below the display board 3 is provided. Can be prevented.

  According to the instrument device 1 of the embodiment, since the outer peripheral edge portion of the display board 3 protrudes upward and is provided with the annular step portion 32 having substantially the same height as the pointer 4, the shaft portion 5 is raised. However, for example, when the instrument device 1 according to the embodiment is viewed from the passenger seat side of the automobile, the stepped portion 32 becomes an obstacle, and the reflection surface (mirror surface) of the large-diameter portion 41a is formed as shown by a one-dot chain line in FIG. The second scale part 22 can be viewed only from an angle at which the second scale part 22 does not appear. Accordingly, it is possible to suppress a reduction in visibility due to the second scale portion 22 being reflected on the reflection surface (mirror surface) of the large diameter portion 41a.

  Further, when a display unit for digital display is provided on the display board 3, the display unit is also projected upward to substantially the same height as the pointer 4, and the peripheral surface of the display unit protruding upward is defined as a reflective surface (mirror surface). By doing so, the digital display on the display unit is also visually recognized as floating in the air, and the appearance of the instrument device can be improved.
