Abstract
A scanning gun comprises a scanning unit, a photoelectric conversion unit, a function selection module, a storage module, a differential recognition module and a comparison output module. The scanning unit is used for scanning a target image and outputting a corresponding image signal through the photoelectric conversion unit. The function selection unit is connected with the photoelectric conversion unit and also connected with a display. The scanning gun selects a scanning function or a detecting function through the function selection module. The differential recognition module is connected to the photoelectric conversion unit sequentially through the storage module and the function selection module. The differential recognition module is further connected to the display through the comparison output module. The scanning gun is suitable for detecting component anomalies so as to improve productivity.
