Abstract

PURPOSE:To enable easy and quick comparison, evaluation and discrimination of jewels by adding index numbers to all the jewels and by preserving data corresponding thereto. CONSTITUTION:In order to obtain a series of figures which can be inputted in a microcomputer MC, a light separated in a prism 6 and passing through a lens 3E is made to fall on a photobridge PS, and the brightness ratio of the light is delivered as a DC voltage value from PS. This value is subjected to V/F conversion VF and counted as a pulse frequency by a counter CU. The counted value thus obtained is delivered as a BCD code and made to be BCD of eight bits by a converter DC. A refractive index and other data thus obtained are given to ICCPU2 in MC and stored in a specified address of a memory PROM. Figures printed and carved on a jewel are preserved as indexes.
