Abstract
The present invention discloses a sample disc which supports internal-external ring bar code scanning. The sample disc comprises a circular tray and one circuit of inner reagent bottle seat and one circuit of outer test-tube clamp seat which are arranged along the circumference of the tray. The inner reagent bottle seat and the outer test-tube clamp seat are staggered. An inner optical path groove is formed between adjacent outer test-tube clamps. Each outer test-tube clamp seat is equally provided with a base and four paws extending upwards from the upper surface of the base with a cantilever shape. Fore paws are in a same circumference and are arranged with a rectangle shape. A front notch, a back notch and two side notches are formed among four paws. Besides, the width of the side notch is larger than the widths of front notch and back notch. As the width of side notch is larger than the widths of front notch and back notch, when the pitch of the outer test-tube clamp set is definite, the width of inner optical path groove which is provided for the passing-through of the inner bar code scanning ray is facilitated to obtain a maximum effective value, namely the pitch of the adjacent outer test-tube clamp seat is minimized at the state that the width of the inner optical path groove is definite.
