Abstract
A combination meter has an indicator for radiating light having entered from an entrance portion thereof and a display panel having a displaying portion illuminated by light passing through such portion. A cylindrical body is inserted into a panel-side opening of the display panel. The cylindrical body has a body-side supporting portion so as to hold the display panel between the body-side supporting portion and a housing-side supporting portion. An outer peripheral reflecting portion formed in the cylindrical body reflects light toward a housing-side reflecting portion of a housing. Light emitted from a light source not only illuminates the indicator but also is reflected by the respective reflecting portions to illuminate the displaying portion.
Claims5
An indicator displaying device comprising:
- a rotatable indicator;
- and
- a display unit for displaying information together with the indicator,
- wherein the rotatable indicator includes;
- a shaft portion around which the indicator is rotated;
- and an entrance portion through which light enters the indicator, so that the indicator is illuminated by the light having entered from the entrance portion;
- wherein the display unit includes;
- an opening through which the shaft portion passes;
- and a displaying portion provided at an outer peripheral side of the opening and illuminated by light passing therethrough;
- wherein the indicator displaying device further comprises;
- a first light source opposing to the entrance portion in an axial direction of the shaft portion across the opening, the first light source emitting light which enters the entrance portion;
- a housing having;
- a housing-side supporting portion for supporting the display unit;
- and a housing-side reflecting portion for reflecting light toward the displaying portion;
- and
- a cylindrical body inserted into the opening in the axial direction of the shaft portion, the cylindrical body having a body-side supporting portion in order to hold the display unit between the body-side supporting portion and the housing-side supporting portion, the cylindrical body further having an outer peripheral surface which is tapered in a direction toward the first light source and which forms an outer peripheral reflecting portion for reflecting the light from the first light source toward the housing-side reflecting portion.
