<p>PURPOSE:To facilitate the stock, movement, and shop control of jewels and ornaments by providing an identification number read means, a precise measuring means, an electric resistance precise measuring means, a spectral analyzing means, and an electronic information processing means. CONSTITUTION:This device is equipped with the identification number read means M1 which reads a previously added number-through an optical device, converts the read number into an electric signal, and outputs the signal and the precise measuring means M2 which precisely measures the total weight of a jewel and a metallic part, converts the measured respective weight values into electric signals, and outputs them. Further, the device is equipped with the electric resistance precise measuring means M3 which supplies a constant current to a set identification point to precisely measure electric resistance, the spectral analyzing means M4 which projects light in a specific band to analyze the spectrum of its reflected light, converts its analytic information into an electric signal, and outputs it, and the electronic information processing means 5 which processes and stores the electric signals outputted by the means M1-M4 as information. Consequently, the optical and physical information on the jewel can be controlled by the electronic information processing means M5.</p> |
