PURPOSE:To identify gems and jewels very easily in a short time, by measuring quantities of gems and jewels to be measured before lending them and storing these quantities and measuring quantities of returned gems and jewels similarly to compare these quantities with data stored beforehand. CONSTITUTION:A measured value obtained in a measuring part S1 for weight is converted to a series adapted to the input of a microcomputer MC by converting parts CC1-CCn and is inputted to an input/output part I/O of the microcomputer MC. A measured value obtained in a measuring part S2 for average specific gravity is converted to a series adapted to the input of the microcomputer MC by converting parts and is inputted to the input/output part of the microcomputer MC. A measured value obtained in a measuring part S3 (for angle or the like) is inputted to the input/output part of the microcomputer MC similarly. Plural data are processed in a central control IC through a bus line and are stored in a storage part MEMO. Data of a gem or jewel returned from a borrower are inputted to the part I/O by the similar method and are compared with data of the gem or jewel to be identified, which is stored beforehand, through a central control part CPU. The comparison result is indicated on an identification indicator IND. |
