A sample plate for supporting bar code scanning is provided, comprising first-circle sample slots distributed along the circumference of the sample plate and clear slots each communicating correspondingly with each of the sample slots, wherein an angle &#x3b1; is formed between the line connecting the center of the circle of each first-circle sample slot to that of the sample plate and the axis of the corresponding clear slot, and the range of &#x3b1; is 4&#xb0;&#x3c;&#x3b1;&#x3c;8&#xb0;. As an angle is formed between the direction of the axis of the clear slot and that of the diameter of the sample plate, it is able to guarantee a reasonable range of the incident angle when the bar code scanning light is projected on the surface of the bar code.
