Abstract
The colorimetry apparatus includes a light source for emitting light to a surface of a detected object, a diffraction grating for spectrally separating, for each wavelength, the light emitted from the light source and reflected by the detected object, and a line sensor including multiple pixels, for receiving the light, which is spectrally separated by the diffraction grating, for the each wavelength by the multiple pixels. The light source and the line sensor are arranged on the common substrate.

1-11. (canceled)
A colorimetry apparatus comprising:
- a light emitting source configured to emit light to a surface of a detected material;
- a spectral unit to disperse the reflected light reflected on the detected material;
- a light receiving device configured to receive reflected light dispersed by the spectral unit to output signals regarding color components of the reflected light;
- a common electronic circuit substrate on which is provided a circuit to control the light emitted from the light emitting source and to process the signals regarding color components of the reflected light, the signals having been output from the light receiving device,
- wherein the light emitting source and the light receiving device are mounted on a common surface of the common electronic circuit substrate.
