SAMPLE CARRIER IDENTIFICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a sample carrier identification device that can read more inexpensively ID codes indicating the kinds of sample carriers set in a chamber and can be set up easily in a vacuum chamber. SOLUTION: This sample carrier identification device identifies a sample carrier 65 which transports a sample 1 in the vacuum chamber by holding the sample 1. This device is provided with optical structure means B1-B4 which detect 1-bit logical signals provided at prescribed spots of the carrier 65 and optical sensor means S1-S2 which detect the logical signals by projecting detection light upon the prescribed spots of the carrier 65. This identification device is also provided with n sets of combinations of the optical structure means B1-B4 and optical sensor means S1-S2 for identifying the ID of the carrier 65.
