Abstract
A pointer type indicator comprises a dial plate 30 having indexes corresponding to measured values and a pointer 10 for pointing respective indexes of the dial plate 10. Said pointer 10 includes a pointing portion 103 to be illuminated by light emitted from a pointer light source 102, and light guide means 103d, 101d, 101e, 104 for guiding a part of light emitted from the pointer light source 103 to illuminate a limited area of the dial plate 30 behind the pointing portion 103. Therefore, even in night, the part of the dial plate behind the pointing portion is illuminated to make the dial plate pointing by the pointer visible. Moreover, since just the limited area around the pointing portion on the dial plate is illuminated, a novel and interesting visibility can be offered.
Claims10
A pointer type indicator comprising:
- a dial plate having indexes corresponding to measured values;
- and
- a pointer for pointing respective indexes of the dial plate,
- whereby said pointer includes a pointing portion to be illuminated by light emitted from a pointer light source and light guide means for guiding a part of light emitted from the pointer light source to illuminate a limited area of the dial plate behind the pointing portion.
A pointer type indicator comprising:
- a dial plate having indexes corresponding to measured values;
- and
- a pointer for pointing respective indexes of the dial plate,
- whereby said pointer includes a base assembly, a pointer light source supported by the base assembly, a pointer cap which has a notch at one part thereof and is attached to the base assembly, a pointing portion fixed to the pointer cap to be illuminated by the light emitted from the pointer light source, and a light guide means for guiding a part of the light emitted from the pointer light source through the notch and illuminating a limited area of the dial plate behind the pointing portion.
