Paper money thickness detection module and ATM money checking device

Abstract

The invention discloses a paper money thickness detection module and an ATM money checking device. The paper money thickness detection module comprises a mounting support, an upper pressing roller assembly and a displacement sensor assembly. The upper pressing roller assembly comprises elastic supports and rollers, and the rollers are mounted at the cantilever ends of the elastic supports. The mounting support comprises a bar-shaped top plate, and the upper pressing roller assembly is fixed on the bar-shaped top plate through the fixed ends of the elastic supports. The displacement sensor assembly is mounted on the top plate of the mounting support, and displacement sensors are opposite to the cantilever ends of the elastic supports. The ATM money checking device comprises a body, an upper module and the paper money thickness detection module. The body comprises a shell and a thickness detection shaft, the two ends of the thickness detection shaft are supported by the shell, and the mounting support of the paper money thickness detection module is fixed on the shell of the upper module through screws. The rollers of the upper pressing roller assembly on the paper money thickness detection module are pressed on the thickness detection shaft. The paper money thickness detection module is simple in structure, and convenient to assemble, mount and store.

Description

[technical field] [0001] The invention relates to an ATM machine, in particular to a banknote thickness detection module and an ATM banknote checking device. [Background technique] [0002] The banknote checking department of the ATM machine needs to detect the thickness of banknotes during the banknote checking process. The Chinese utility model patent No. 201020186009 discloses a banknote thickness detection device of a currency counting and detector, which includes left and right fixed brackets, a thickness detection shaft and a component connecting frame connected between the left and right fixed brackets. The upper and lower parts of the component connecting frame are respectively provided with a number of one-to-one corresponding infrared displacement sensor assemblies and upper pressure roller assemblies; the infrared displacement sensor assemblies can detect the vertically rising displacement of their corresponding upper pressure roller assemblies; all The upper pre...
