Pen-type barcode scanner
First Claim
1. A barcode scanner for reading barcode image carried by an object, comprising:
- a cylindrical housing having a barcode approaching end and an output end opposite to said approaching end, and a scanning apparatus located within said housing;
said scanning apparatus including a focusing device, a light source device, a signal receiving/converting device, and a printed circuit board carrying said devices, said focusing device and signal receiving/converting device being located in a central line passing a center of an aperture located in said approaching end and on while said a lens is seated, wherein reflected barcode image is picked up by said focusing device, and then transferred to said receiving/converting device in which said reflected barcode image is processed, a processed signal then being forwarded to said printed circuit board and converted into a digital signal for further processing; and
wherein said light source device is configured by a LED chip which is located aside said central line and between said approaching end and said signal receiving/converting device.

Abstract
A pen-type barcode scanner for reading barcode image carried by an object. The barcode scanner features brightened and concentrated reflected light reflecting from the barcode image thereby benefiting a more reliable inlet signal. In addition, the energy used can be saved while the reliability is increased. The barcode scanner features a light source device, i.e. an LED chip, which is located on a light path adjacent to an approaching end. By this arrangement, the emitted light can be completely projected onto the barcode image thereby enhancing a reflected light from the barcode. Accordingly, the reflected light can be readily processed to decode the information carried by the barcode.
