Embodiment Construction
[0035] Embodiments of the present invention are described in detail below:
[0036] like figure 1 , figure 2 , image 3 As shown, a sheet medium thickness detection device includes a base 10, a power shaft 20, a first thickness detection component 30, a second thickness detection component 40, and a computing module. The power shaft 20 is installed on the base 10, the first thickness detection assembly 30 is hinged on the base 10 and both engage with the power shaft 20, wherein the engagement refers to the first thickness detection assembly 30 , The second thickness detection component 40 is in a contact state with the power shaft 20 . The meshing area between the first thickness detection component 30 and the power shaft 20 forms a sheet medium transmission channel 50 , and the first thickness detection component 30 is used to obtain a thickness detection signal of the sheet medium. The second thickness detection assembly 40 is arranged in cooperation with the power shaf...

The invention discloses a thickness detection apparatus and method for a sheet type medium, and a financial self-service device. The thickness detection apparatus comprises a pedestal, a power shaft, a first thickness detection assembly, a second thickness detection assembly and an operation module. The power shaft is installed on the pedestal. The first thickness detection assembly hinged to the pedestal is engaged with the power shaft. The second thickness detection assembly cooperating with the power shaft is arranged at an area where a sheet type medium does not pass by when being transported. The operation module is connected with the first thickness detection assembly and the second thickness detection assembly electrically. With the method and system and the financial self-service device, a processing error and an assembling error of the power shaft can be identified and removed effectively; and thus the processing difficulty and the processing cost of the power shaft are reduced and the assembling requirement is reduced. Moreover, the actual thickness value of a sheet type medium can be reflected accurately.
Description
technical field [0001] The invention relates to the field of thickness detection, in particular to a device and method for detecting the thickness of a sheet medium, and financial self-service equipment. Background technique [0002] Thickness detection of valuable documents such as banknotes, checks, money orders, etc. is an important means to identify counterfeit coins, tape banknotes, and double banknotes. Since the thickness of the sheet medium is very thin, when judging anti-counterfeiting, double sheeting, etc. based on the thickness detection results of the sheet medium, the detection accuracy requirements of the thickness detection device are particularly high. Most of the traditional thickness detection devices are based on the principles of magnetic detection, optical detection, and eddy current detection. [0003] The power shaft is used as a power input source and a thickness measurement benchmark, and its accuracy guarantee is very important for the accuracy of...
