Color identifying device for identifying colors of reaction surfaces produced by chemical reaction and gas identifying device

A gas identifying device comprising:

• a mount block for mounting a reactive board having a plurality of reaction surfaces disposed in predetermined positions, respectively, said reaction surfaces comprising colors variable by chemical reactions between a gas to be identified and chemical reagents;
• a color detector comprising a plurality of color measuring areas corresponding respectively to said reaction surfaces while said board is mounted on said mount block;
• a lens for forming respective images of said reaction surfaces of said board mounted on said mount block, respectively on said color measuring areas corresponding respectively to said surfaces;
• and
• a gas identifier for identifying said gas based on output signals from said color measuring areas corresponding respectively to said surfaces.

A color identifying device comprising:

• a plurality of surfaces to be simultaneously measured;
• a color detector having a plurality of color measuring areas corresponding respectively to said surfaces;
• a lens for simultaneously forming images of said surfaces on said color measuring areas corresponding respectively to said surfaces;
• and
• a color identifier identifying colors of said surfaces which correspond respectively to said color measuring areas.
