Abstract
Provided is a transparency scanner having a light source which is synchronously moved with the image sensor of the scanner by using magnetic force to establish a solid connection between the transparency scanning light source and the image sensor while scanning a transparency. A motor is used to synchronously move the transparency scanning light source and the image sensor to avoid the errors produced by driving devices such as different motors or gears, etc. Therefore, synchronous movement of the transparency scanning light source and the image sensor can be ensured, and the deterioration of the scanning quality due to various distributions of the intensity of the light source can also be avoided.
