Title:
An image forming device provided with a color measuring device and it
Document Type and Number:
Japanese Patent JP6278625
Kind Code:
B2
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.
