Abstract: A device for detecting thickness and thickness variation of a sheetlike object, includes at least a first guiding component, a plurality of second guiding components, a plurality of detection units and a position sensor. An up-down displacement occurs between the first guiding component and the second guiding components while the sheetlike object passed through the first guiding component and those second guiding components. The detection units are configured relatively to second guiding components, each of the detection units further comprises a detecting block, a first elastic member, a second elastic member and a fixing member, the first elastic member and a second elastic member connect with the second guiding component via the detecting block, while the displacement occurs at the second guiding component, a sensing face to detected of the first elastic member is having a parallel displacement relative to the position sensor.

Abstract: A sensing method for a counterfeit bill detector includes (i) using multiple image-sensing modules to scan multiple pieces of image information of a bill and converting the multiple pieces of image information into multiple values of digital image, (ii) comparing each value of digital image with a pre-stored image threshold value to generate a reference value, (iii) adding the multiple reference values to generate an image validation value, (iv) comparing the image validation value with a pre-stored validation threshold value to acquire a comparison result, and (v) determining if the multiple pieces of image information are valid according to the comparison result. The sensing method tackles the issue of unsynchronized actions in bill sensing and bill scanning and simultaneously eliminates the problem of distorted scanned bill image arising from entry of misaligned bill to improve accuracy in bill validation.

Abstract: A device for detecting thickness and thickness variation of a sheetlike object, includes at least a first guiding component and a plurality of second guiding components, deviation between the first guiding component and the second guiding components occurs while the sheetlike object passed through among the first guiding component and those second guiding components; a elastic member, having a first elastic displacement end, a second elastic displacement end and a elastic member fixed surface, both of the first elastic displacement end and the second elastic displacement have a plane disposed thereto and served to connect with each side of a movable elastic member, while the elastic member fixed surface is to fix the elastic member; and a displacement sensor is configured to detect a displacement of a side face on the first elastic displacement end. The present invention has the ability to raise the accuracy of the thickness and thickness variation detection.
