Description

  The present invention relates to a pointer-type instrument device employed in, for example, a vehicle instrument, and more particularly to a pointer-type instrument device in which a ring-shaped decorative member is disposed around a display area on a display board of the instrument device. is there.

  As a conventional pointer-type instrument device, for example, one disclosed in Patent Document 1 is known. This pointer type instrument device is provided with an outer peripheral ring made of a transparent material coaxially disposed on the outer peripheral side of the scale plate, and provided with a pointer as a light guide member and a light emitting diode as a first light source as selective light emitting means, The light from the light emitting diode is made to enter the outer ring from the tip of the pointer, which allows the pointer and the portion of the outer ring that hits the extension of the light emitting surface in the radial direction of the pointer to emit light. Visibility equivalent to the case of extending to the outer ring on the outer diameter side of the can be obtained, so that a combination meter with a novel appearance can be provided while improving the visibility of the speed instruction by the observer (driver). .

  Moreover, what is disclosed by patent document 2 is known as another means. In this pointer-type instrument device, a plurality of divided prisms are arranged in an arc shape on a dial plate that is an outer peripheral region of the pointer, and a scale is printed on the prism, which is the tip of the pointer. The prisms are individually brightly illuminated by the light from the light projecting unit, and the visibility of the indicated scale is improved by being illuminated brighter than other prisms.

  However, the instrument device described in Patent Document 1 makes light emitted from the tip of the pointer enter the outer ring and project the light on the outer ring in accordance with the turning operation of the pointer, thereby making the length of the pointer longer and visibility. However, there is a problem that the light projected on the outer ring is monotonous and lacks commerciality and novelty. Further, in the pointer-type instrument device described in Patent Document 2, it is necessary to continuously arrange the prisms installed on the dial plate, and the assembly work becomes troublesome as the number of parts increases. have.

  Therefore, the present invention solves the above-described problems, and in the instrument device that irradiates the ring-shaped decorative member with light from the tip of the pointer, while improving the merchantability and improving the assembly workability, It is an object of the present invention to provide an instrument device capable of obtaining a novel lighting effect.

  In order to solve the above-described problems, the present invention provides a circuit board assembled to a case, an instrument main body assembled to the circuit board or the case, and a tip end side of a drive shaft provided on the instrument main body. A display plate having a display portion composed of a pointer to be attached, a scale indicated by the pointer, a character, and the like, and a ring-shaped decorative member disposed on the front side of the display plate so as to surround an operation region of the pointer A first light source mounted on the circuit board and entering the base portion of the pointer and supplying illumination light to the pointing portion of the pointer, and mounted on the circuit board and behind the display board A second light source for transmitting and illuminating the display unit from the side, wherein the decorative member is made of a transparent resin material and forms a part of an indicator portion indicated by the pointer When, A second decorative member made of an impermeable resin material formed integrally with the first decorative member, and the display plate has the ring shape disposed on the outer peripheral edge of the display unit A transmitting portion is provided corresponding to the position of the indicator portion provided on the decorative member, and the pointing portion of the pointer includes a first light emitting portion that guides light to an observer, and a tip of the pointing portion. A second light emitting unit that irradiates the inner surface of the decorative member, and the second light source transmits and illuminates the display unit on the display plate, and the display unit is provided with the display unit. The indicator portion provided on the first decorative member is transmissively illuminated via a transmissive portion, and the first light emitting portion of the pointer is illuminated by the first light source, and the second light emitting portion. The indicator portion is transmitted and illuminated by a light beam directed toward the decorative member via It is an instrument apparatus according to claim.

  By configuring in this way, the pointer indicating unit is brightly illuminated because it is illuminated by the light of the first light source irradiated to the first light emitting unit, and the display unit provided on the display board is the second unit. And the indicator portion provided on the first decorative member is transmissively illuminated through the transmissive portion provided on the display plate, so that the display portion on the display plate and the display plate A second light-emitting unit provided at the tip of the pointer indicating unit can be illuminated and transmitted in a three-dimensionally arranged manner with the indicator portion of the decorative member arranged on the top, and at the same time, an illumination display with a sense of depth can be achieved.
