A barcode scanner is provided to reduce the number of parts and unnecessary space, realize a compact size, shorten assembly time, improve productivity, and firmly combine a main frame housing with a PCB(Printed Circuit Board) more than a present manner. Each LED(Light Emitting Diode)(11) lights an image of a reading target storing information. A camera lens(21) captures the image. A laser diode(25) irradiates a guide beam to the image to display a reading part. A collimator lens(31) transforms the guide beam irradiated from the laser diode into a linear beam. A pattern lens(35) images the guide beam passing the collimator lens on the image by using a specific pattern. The main frame housing(41) supports the LEDs, the camera lens, and the collimator lens. An LED scattering lens(71) scatters light irradiated from the LEDs at an upper part of the main frame housing. The PCB(65) is layered on the main frame housing, and is electrically connected to the LEDs having one end penetrating the main frame housing. |
