Abstract

The invention relates to a device for measuring thickness, in particular to a testing device for thickness of a slice medium. The testing device comprises a fixed mount, a reference shaft, a testing shaft, an elastic press sheet, a magnet, and a Hall sensor, wherein two ends of the reference shaft are installed on the fixed mount by bearings, the reference shaft is fixedly sleeved with a reference roller; two ends of the testing shaft are fixedly installed on the fixed mount; the testing shaft is provided with at least one testing roller base of which one end is rotated freely around the testing shaft; a free end of the testing roller base is provided with a testing roller which can rotate freely; the testing roller and the reference roller are formed in elastic contact; the elastic press sheet is arranged correspondingly to the testing roller base; one end of the elastic press sheet is fixed on the fixed mount and the other end of the elastic press sheet forms a free end and applies a pressing force to the testing roller base at the reference roller; the free end of the elastic press sheet is fixedly provided with the magnet on the opposite side to the testing roller; and the Hall sensor for testing the displacement of the magnet in a non-contact mode is fixed on the fixed mount opposed to the magnet.

Description

technical field [0001] The invention relates to a device for measuring thickness, in particular to a detection device for detecting the thickness of thin sheets of valuable documents in financial self-service equipment. Background technique [0002] In the financial self-service equipment, in order to inspect each sheet of valuable documents (such as banknotes) processed in batches one by one, it is necessary to separate the stacked sheet of valuable documents one by one, and then separate the separated single sheet of valuable documents Valuable documents are identified by image recognition, thickness detection, magnetic information detection and other identification methods to ensure the authenticity of the processed thin sheet valuable documents, among which thickness detection is essential in the entire detection, and the thickness detection information can be used To judge the authenticity of the processed thin sheet valuable documents, it can also judge whether the mec...
