Abstract

An indication instrument with improved illumination efficiency. The indication instrument has an indication panel (100), an indication plate (200) on which index parts (201) are disposed along the outer periphery of the indication panel (100), a pointer (11) for indicating the index parts (201), a drive source (7) for driving the pointer (11), and an indication plate light source (light source) (700) for illuminating the indication plate (200). The pointer (11) is routed around the rear of the indication panel (100) to reach the front of the indication plate (200). The indication instrument further comprises a frame (300) for joining to each other the indication panel (100), the indication plate (200), and the light source (700). An illumination chamber (R1) for guiding the light of the light source (700) to the indication plate (200) is formed in the frame (300).

Description

technical field [0001] The present invention relates to a pointing device mounted on a vehicle, etc., and relates to a pointing device of the type in which the pointer is placed in the middle of a pointer-type display part formed by a pointer and a display panel, in order to display information on an electronic display panel. The rear is roundabout and extends to the front of the display panel. Background technique [0002] As such an indicating device, for example, a type described in Patent Document 1 below is known. The indicating instrument includes a display panel formed of a liquid crystal panel; a display panel with an indicator portion arranged along the periphery of the display panel; a pointer indicating the indicator portion; ); the circuit substrate on which the driving source is installed and arranged at a predetermined distance from the display panel; the light source arranged in front of the front panel of the circuit to illuminate the display panel and the d...
