Description

  The present invention relates to a pointer instrument having a rotating pointer and a scale board, and is effective when applied to a speedometer and a tachometer for a vehicle.

As a conventional pointer instrument, for example, a liquid crystal display as a display means is provided on the rotation center side of the pointer from the scale portion of the scale plate, and the pointer is provided by a light source for pointer mounted on the base placed behind the scale plate. There is a configuration that displays light emission (see Patent Document 1).
JP 2002-39807 A

  By the way, in the above-described conventional pointer instrument, the pointer light source is mounted on the substrate offset from the center of rotation of the pointer. This is because the substrate is provided with a through-hole through which the rotation shaft of the pointer is inserted, and it is impossible to dispose the pointer light source on the pointer rotation center.

  For this reason, in the conventional pointer instrument, it is necessary to arrange a plurality of light sources in a circular arc concentric with the rotation axis in order to display and display the pointer with uniform brightness over the entire rotation angle range. There is a problem that the cost of the pointer instrument increases.

  The pointer is provided with a reflecting surface that reflects light from the light source incident on the pointer toward the tip of the pointer. In a conventional pointer instrument, the reflecting surface is a light source arranged in a plurality of arcs. Is formed on a boss portion for attaching the pointer to the pointer shaft so as to be substantially concentric with the rotation shaft of the pointer. Normally, in a pointer instrument, the boss portion is configured so that it cannot be seen by a viewer in order to improve the appearance of the pointer instrument.

  The conventional pointer instrument has a problem that the design of the pointer instrument is restricted because the boss portion is enlarged for the reason described above.

  In view of the above-described points, an object of the present invention is to provide a pointer instrument that can devise a pointer illumination structure, suppress an increase in cost, and reduce the boss portion of the pointer.

  In order to achieve the above object, the present invention employs the following technical means.

  A pointer instrument according to claim 1 of the present invention is a scale plate having a display design, a pointer rotating around the pointer shaft along the surface of the scale plate, and a pointer shaft disposed on the back side of the scale plate. A rotating inner unit to be rotated, a substrate disposed on the back side of the dial plate and to which the rotating inner unit is fixed, a part of the pointer and a display design of the scale plate that are overlapped on the viewer side with respect to the pointer in the viewing direction. In a pointer instrument comprising: display means arranged to be visually recognized; a light source arranged on a substrate; and a light guide means for guiding the light of the light source to the display means to transmit and illuminate the display means. An irradiation part provided on the back of the display means so as to emit a light beam toward the pointer on the center of the axis, and a light beam incident on the pointer provided so as to intersect the center of the pointer shaft on the pointer And a reflecting surface that reflects in the direction.

  According to this configuration, the light emitted from the irradiating unit toward the pointer is always incident on the reflecting surface regardless of the rotation angle of the pointer, and the pointer is lit and displayed.

  This eliminates the need for arranging a plurality of light sources on the substrate along the arc as in a conventional pointer instrument, and can suppress an increase in cost by minimizing the number of light sources. Moreover, since the size of the reflecting surface provided on the pointer can be reduced, the boss portion of the pointer can be reduced in size. Therefore, it is possible to realize a pointer instrument that can suppress an increase in cost and can downsize the boss portion of the pointer.

  According to a second aspect of the present invention, the pointer instrument includes a second light source disposed on the substrate, and a second light guide unit that guides light from the second light source to the irradiation unit. It is characterized by being formed as part of the light means.

  According to this configuration, an electric circuit to the second light source can be easily formed by disposing the second light source for pointer illumination on the substrate.

  The pointer instrument according to claim 3 of the present invention is characterized in that the irradiating part is formed as a part of the light guiding means, and a part of the light from the light source is emitted from the irradiating part.

  According to this configuration, since the pointer is also illuminated using the light source and the light guiding means for the display means transmitting illumination, the increase in cost is suppressed without increasing the number of component parts and assembly man-hours of the pointer instrument, and the pointer A pointer instrument that can reduce the size of the boss can be realized.

Then, the light is reflected by the reflecting surface 31 and proceeds toward the tip of the pointer 3.

  According to this configuration, the reflecting surface 82 that irradiates light toward the pointer 3 and the reflecting surface 31 of the pointer 3 are both arranged so as to intersect the rotation center axis C of the pointer 3. Therefore, regardless of the rotation angle position of the pointer 3, the incident light is always incident on the reflecting surface 31, and the amount of light incident on the reflecting surface 31 from the reflecting surface 82 is always constant. In other words, the pointer 3 can be lit and displayed with stable brightness over the entire rotation range.
