Description

  The present invention relates to a scanner, and more particularly to a pocket scanner.

  In a conventional handheld linear scanner, the optical members are arranged in a straight line. Therefore, the horizontal line of the image needs to complete the scan in the same time or in the same process, and the length of the optical image member needs to be longer than the scan length defined in the standard. Therefore, all products have a rectangular shape, which is disadvantageous for carrying around.

  A conventional mouse scanner is provided with a two-dimensional array type optical sensing image member and a position sensor. All the two-dimensional images obtained in each scanning process are read at the time of scanning, and based on the obtained relative position information, all the small images are pasted together into a large image by software. This can greatly reduce the length of the product, but it has the three dimensions of mouse outline, product length, width, height, not only to meet the needs of operation, The circuit board must be accommodated. Among them, the optical structure in the light engine and the shape of the outer shell have an important influence on the outer size of the product.

  An object of the present invention is to provide a pocket scanner that is convenient to carry with respect to the above-mentioned known shortages.

To achieve the above object, a pocket scanner according to the present invention includes a light engine module, a circuit board module, and an outer shell module.

The main control circuit board is installed above the light engine module and is perpendicular to the scan window. A scan controller and an image processor are installed on the main control circuit board, and an oblique side corresponding to the slope of the light engine module is installed below the main control circuit board. The hypotenuse is in close contact with the slope and minimizes the space after assembly of the light engine module and the main control circuit board.
The support frame is installed above the light engine module on one side of the main control circuit board, and a battery module tank is opened on one side of the support frame facing the main control circuit board.
The battery module is accommodated in the battery module tank, electrically connected to the main control circuit board, and supplies a voltage to a scan controller and an image processor of the main control circuit board.
The outer shell module covers the light engine module and the circuit board module, and the outer shell module has a lower lid, an upper lid, and two side lids.
The light engine module is installed on the lower lid, the upper lid covers the lower lid, the two side lids cover both the lower lid and the upper lid, and the lower lid Corresponding to the scan window of the light engine module, a scan window is opened, and the light engine module scans through the scan window. Glass is installed on the scanning window to prevent the entry of external objects into the light engine module.

  The pocket scanner of the present invention installs a slope on the shell of the light engine module, and the main control circuit board of the circuit board module corresponds to the slope of the light engine module. The space between the light engine module and the main control circuit board can be surely minimized by sticking to the slope, thus making the pocket scanner of the present invention compact and improving the convenience of carrying.
