Abstract

The invention discloses a method for locating a scanning module and a scanning device applying the method. The method comprises the steps of: scanning a bar code pattern to obtain an image, wherein the bar code pattern is arranged in a region outside a flat scanning window of the scanning device; recognizing an image, judging whether the image is a location point pattern; and when judging that the image is the location point pattern, setting a scanning starting line according to the image, moving the scanning module to the scanning starting line. According to the method for locating the scanning module and the scanning device applying the method, the scanning module can be accurately located according to the position of the bar code pattern by additionally arranging the bar code pattern without additionally arranging a protection wall and a location sensor. Therefore, the quantity of assemblies can be reduced, assembling procedures are simplified and manufacture cost is saved.

Description

technical field [0001] The invention relates to a scanning device, in particular to a positioning method for a scanning module of the scanning device. Background technique [0002] In the basic structure of a general scanner, the scanning module will include an optical sensor and a transmission mechanism. The scanning module is used for capturing the image of the object to be scanned. After each scan is completed, the scanning module needs to return to the positioning. The traditional detection and positioning method is to install a protection wall and a home sensor in the direction where the scanning module moves to the positioning point. When the scanning operation is finished, the transmission mechanism moves the scanning module, and when it reaches the positioning point, the positioning sensor sends a detection signal to stop the transmission mechanism, and the scanning module stops at the positioning point, waiting for the next scanning operation to start. However, i...
