Pocket scanner

A pocket scanner for converting an original to a digital image, comprising:

• an optical engine module including a frame, a bottom of the frame defining an elongated scanning window, the long side of the scanning window being parallel with the long side of the bottom of the frame, a top of the frame of the optical engine module being designed with a slant plane slantwise facing the scanning window;
• a printed circuit board (PCB) assembly including a control PCB, a bracket and a battery module, the control PCB being located above the optical engine module and perpendicular with the scanning window, a bottom of the control PCB being designed with a slant edge corresponding to the slant plane of the optical engine module, the slant edge of the control PCB being against the slant plane of the optical engine module when assembly, the bracket being mounted to a side of the control PCB and above the optical engine module, one side of the bracket back to the control PCB being opened with a receiving cavity, the battery module being received in the receiving cavity and electrically connected to the control PCB;
• and
• a cover assembly enclosing the optical engine module and the PCB assembly, the cover assembly including a bottom cover, a top cover and two side covers, the optical engine module being mounted on the bottom cover, the top cover covering on the bottom cover, the two side covers being respectively covered to two sides of the bottom cover and the top cover, the bottom cover being opened with a scanning opening corresponding to the scanning window of the optical engine module, a glass being equipped in the scanning opening;
• wherein the optical engine module is electrically connected to the PCB assembly and scans the original through the scanning opening and the scanning window to obtain image information, the control PCB of the PCB assembly receives and processes the image information into the digital image.
