PROBLEM TO BE SOLVED: To read even the bar code of the reagent bottle placed on the innermost rotary stand when reagent placing stands are arranged in a concentric circular state. SOLUTION: Arranging means (rotary stands 2, 3, 4) of members to be detected arranged in a concentric circular state can be respectively independently rotated and the arranging means (rotary stands 3, 4) of the members to be detected excepting at least the innermost arranging means (rotary stand 2) of the member to be detected are equipped with reading spaces (chambers 3A, 4A) for reading discrimination codes (bar codes) by a code reading means (bar code reader 106) and, when the inside discrimination code is read, the arranging means 2, 3, 4 of respective members to be detected are driven to arrange the reading spaces 3A, 4A and the discrimination codes are read by the code reading means 106. |
