Provided is a blind spot assist device capable of more easily showing the image of a blind-spot zone continuously with the image directly viewed by a viewer. The blind spot assist device shows the image of the blind-spot zone blocked by an obstacle, and is provided with a pair of parallel plane mirrors to which light representing the image is incident, the pair of parallel plane mirrors comprising a semitransparent plane mirror and a plane mirror opposed to each other. The semitransparent plane mirror is provided on the viewer side for reflecting part of the light and transmitting part of the light. The plane mirror reflects the light to the semitransparent plane mirror. The pair of plane parallel mirrors is provided in such a manner that the width in a direction perpendicular to the travel direction of the light decreases gradually toward the travel direction of the light.

[Problem] To provide an instrument dial and its manufacturing method wherein it is possible to shorten a print time and achieve a reduction in cost. [Means for Resolution] An instrument dial with index portionsprovided in background portionsandby subjecting a substrateto printing includes an underlying portionconfigured of a screen print layer provided on the substrate; a first background portionwhich, being configured of a screen print layer formed on the underlying portion, does not include the index portions; and second background portionswhich are configured of a digital print layer formed on the underlying portionand, as well as including the index portions, are continuous with the first background portion

Instrument dial and its manufacturing method

Disclosed is a pointer type measuring instrument of a novel look, in which an indication portion detours the outer circumference of a display portion and can be visually confirmed as if the indication portion is floating above the display portion. The pointer type measuring instrument (M) comprises a display means (), a drive body () mounted on the back side of the display means (), an arm portion () mounted on the output shaft () of the drive body () and detouring the outer circumference of the display means (), an indicating portion () extending from the arm portion () toward the center of the display means () and indicating an indicator portion () disposed on the display means (), and a first light source () mounted on the arm portion () or the indicating portion () and causing the indicating portion () to glow.

Pointer type measuring instrument

An indicator lighting device in which light introduction efficiency into a indication portion can be improved, brightness is good and unevenness in lighting is small is provided; wherein an indicatorwhich has a translucent indication member (indication portion)and a light introduction member (light introduction portion)and is operated around an axis by a drive shaftof a drive unitlight sources L which are disposed around the drive shaftand illuminate the indication memberthrough the light introduction memberare provided, and the light introduction memberhas a light receiving surfacefor receiving light from the light sources L, a first reflective surfacefor focusing light introduced from the light receiving surfaceto a position of a rotation axis Vof the drive shafta second reflective surfacewhich is formed between the first reflective surfaceand the rotation axis and reflects light from the first reflective surfacein a direction along the rotation axis V, and a third reflective surfacewhich is formed on the rotation axis Vin a way of facing the second reflective surfaceand reflects light from the second reflective surfacein a longitudinal direction of the indication member

Indicator lighting device

The present invention provides an illuminating apparatus capable of carrying out an illumination operation excellently by guiding the light from light sources to an illuminating member efficiently, and having a low price. The illuminating apparatus is provided with a pointeradapted to be turned around a rotary shaft, a dialpositioned on a rear side of the pointerand constituting a display member to be transmission illuminated, light-emitting diodespositioned on a rear side of the dialand in the vicinity of the rotary shaftand constituting light sources for illuminating index portionsof the dial, a casepositioned on the rear side of the dialand constituting a reflector provided with a reflecting portion, and a light guide memberpositioned on the rear side of the dialand adapted to guide the light from the light-emitting diodesto the rear side of the dial. A hollow portionis formed between a rear surface of the dialand case, and an irradiation portionadapted to apply the light to the interior of the hollow spaceis provided on the light guide member, the light from the light-emitting diodesbeing applied from the irradiation portionof the light guide memberto the interior of the hollow portion, reflected on the reflecting portionand illuminating the index portionsof the dial

Illuminating apparatus

There is provided a backlight device which is bright and has low unevenness of luminance, and a backlight device is constituted by a translucent sheet having light diffusibility, a light emitting element disposed behind the translucent sheet , and a prism sheet disposed between the light emitting element and the translucent sheet and having a prism surface on which plural rows of prism portions each having a pair of inclined surfaces (hem sides B and C) intersecting with each other at a top A and a substantially V-shaped section are formed, and a plane surface portion formed on a surface opposite to the prism surface , in which the prism sheet is disposed away from the light emitting element and the translucent sheet by distances W and W so that the prism surface is faced toward the light emitting element

Backlight device

A measuring apparatus in which the necessity of a light conductor for illuminating the front panel can be eliminated and cost reduction and slimming is realized, comprising: a circuit board ; an instrument body disposed on the circuit board and including a drive shaft extending forward; a pointer to be fitted on the tip side of the drive shaft ; a front panel disposed between the pointer and the circuit board for illuminating at least the display portion ; a light source disposed in front of the circuit board on the side where the drive shaft resides with respect to the display portion ; a reflector to be disposed between the front panel and the circuit board ; and the circuit board including a first reflecting portion facing to the light source for reflecting the illumination from the light source toward the outer periphery, and a second reflecting portion extending outward with an appropriate space interposed between itself and the front panel so as to surround the light source for reflecting the illumination toward the front panel
