Description

A scanner capable of preventing CIS trolley from collision

Technical Field

The utility model belongs to the technical field of scanners, and in particular relates to a scanner capable of preventing a CIS trolley from colliding.

Background Art

Contact image sensor, abbreviated as CIS, is a sensor technology used for image capture. CIS usually adopts compact linear photosensitive chips and integrated light sources, making the overall design very thin and suitable for various flat scanning devices and printers. Compared with the CCD sensor used in traditional scanners, CIS usually has lower power consumption, which makes it more suitable for portable devices and embedded systems. When CIS is used on a scanner, the CIS cart on the scanner does not have a HOME sensor. The system cannot quickly determine the position of the CIS cart and whether it is close to hitting the wall. In some cases, the CIS cart will hit the wall, causing damage to the contact image sensor and a decrease in scanning quality.
