Disclosed is an improved indicator, which includes a scale plate having a pointer rotatably mounted thereon; an ultraviolet light source for illuminating said scale plate; and indicia arranged on the scale plate for indicating a specific value in cooperation with the pointer, each of the indicia including first and second parts, and in which the second part includes fluorescent brightener therein so as to be illuminated when the ultraviolet light source is turned on. When the ultraviolet light source is turned on, particularly at night, the second parts of the indicia will become visible so that the visibility of the indicia is changed from the daylight condition in which the light source is turned off. Namely, an interesting design change of the indicia of the indicator can be obtained.
A subjective optometric apparatus comprises: right-eye and left-eye examination units, each including a test window and optical elements that are manually selectively disposed in the test window; an indicator provided in each examination unit, the indicator being arranged to indicate information on the optical element disposed in the test window and generate fluorescence by ultraviolet light; and an illumination unit which includes a light source and illuminates the indicator with the ultraviolet light.

Disclosed is an improved indicator, which includes a scale plate having a pointer rotatably mounted thereon; an ultraviolet light source for illuminating said scale plate; and indicia arranged on the scale plate for indicating a specific value in cooperation with the pointer, each of the indicia including first and second parts, and in which the second part includes fluorescent brightener ink or paint therein so as to be illuminated when the ultraviolet light source is turned on. When the ultraviolet light source is turned on, particularly at night, the second parts of the indicia will become visible so that the visibility of the indicia is changed from the daylight condition in which the light source is turned off. Namely, an interesting design change of the indicia of the indicator can be obtained.
A viewed component of a vehicle instrument cluster includes a dial structure. A printed circuit board is arranged on the dial structure and has an outboard surface. A layer of printed ink is arranged on the outboard surface of the printed circuit board. A series of LEDs are arranged on the outboard surface of the printed circuit board wherein the series of LEDs occupy an outermost layer of the dial structure.
An instrument cluster assembly includes a first instrument cluster graphic and a second instrument cluster graphic. The second instrument cluster graphic is superimposed on the first instrument cluster graphic.
It is object of the present invention to provide a car-carried indicating device which provides a clear indication by the needle and a good readability are secured, and which looks larger than the actual one, leading to improvement of the valid of commodity. In a car-carried indicating device, a character plate 1 includes a substantially circular transparent portion 2 at the indicating position, transparent numerals 3a and a scale 3b being circularly arrayed around the transparent portion 2. A disk-like needle plate 8, which is driven to turn in accordance with given measuring quantities, is made of light diffusion base material. The needle plate 8 is disposed on the front side of the character plate 1. A transparent slit 9 as a needle shining when it receives back-light, which is formed on the needle plate, is extended up to the circumferential outer end of the needle plate 8.
