Phosphor indication device

A phosphor indication device of a meter comprising:

• an indication section formed on an indicator panel and showing a pattern and characters printed on it with a phosphor-containing paint;
• a light source for irradiating the phosphor-containing paint to excite a phosphor to emit light to thereby indicate the pattern and characters in fluorescence;
• the indicator panel and light source are accommodated in a meter casing;
• wherein the pattern and characters on the indicator panel are of at least one phosphor-containing paint which differs in color when exposed to light capable of exciting the phosphor to emit light from when it is exposed to ordinary light unable to excite the phosphor to emit light;
• and
• at least one additional light source unable to excite the phosphor to emit light whereby the light sources can be actuated singly or in combination.

• the indicator panel and light sources are accommodated in a meter casing;
• wherein the pattern and the characters on the indicator panel are of (1) at least one phosphor-containing paint which differs in color when it is exposed to light capable of exciting the phosphor to emit light from when it is exposed to ordinary light unable to excite the phosphor to emit light and (2) ordinary non-fluorescent paints for printing portions adjacent the indication section printed with the phosphor-containing paint.
