Description

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

A scanner is equipment that is externally attached to a computer.
A digital facility that captures an image, converts it to a computer, and can be labeled, edited, stored, and output.

A conventional handheld linear scanner has a linear image sensor, and scans an image by a paper feed type scanning or a linear (one-dimensional) moving method.
The former is heavy and unfavorable for carrying, and the paper must be fed one by one when scanning.
In the latter case, the horizontal line of the image needs to complete the scan in the same time or in the same process, so the length of the optical image member needs to be longer than the scan length defined in the standard.
For this reason, 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.

In order to solve the above problem, the scanner disclosed in Patent Document 1 includes a base and a light engine.
The light engine includes a scan window, a plurality of light sources, a reflector, and an image sensing module.
The scan window and the base are inclined at a constant angle, and the plurality of light sources are installed around the axis of the scan window.
The reflector is placed relative to the scan window and receives and reflects the image in the scan window to change the optical path.
The image sensing module is installed at the edge of the scan window and receives an image reflected by the reflector.
Since the light engine and outer shell of the scanner are relatively small, the size of the product can be reduced.

However, in the prior art scanner, since the light source and the scan window are installed on the same plane, when the reflecting mirror receives and reflects the light beam, a spot of the light source itself is generated.
In addition, there is a drawback that the brightness of the scan area is lowered and the brightness is non-uniform, which results in a poor scanner effect.
