1. A scanning apparatus, the apparatus comprising a rotatable rotation component and a scanning device, and a positioning device, wherein:
the positioning device is configured for positioning the rotation component when the rotation component rotates to different predetermined positions respectively, and the scanning device is configured for scanning an item placed on the positioned rotation component;
wherein, a plurality of positioning marks are arranged at a periphery of a first surface of the rotation component around an axis of a rotation shaft of the rotation component, and each of the positioning marks corresponds to one of the predetermined positions, and a radial distance between each of the positioning marks and the rotation shaft is L;
wherein the positioning device is configured to perform a detection on the rotation component, a detection position of the positioning device is located on the first surface of the rotation component, and a radial distance between the detection position and the rotation shaft is L, so that during a rotation of the rotation component, the rotation component is positioned when the positioning device detects the positioning mark at the detection position.
