Embodiment Construction

[0027] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] figure 2 It is a block diagram of a medium thickness detection device according to the first embodiment of the present invention. As shown in the figure, the medium thickness detection device 100 includes a control unit 11 , a detection roller assembly 12 and a detection circuit device 13 .

[0029] The control unit 11 is used to control other modules to perform work. For example, the control unit 11 controls the detection roller assembly 12 to drive the medium to move in the conveying channel of the medium thickness detection device 100, and the control unit 11 outputs according to the first detection element of the detection circuit device 13 The electric signal of the second detecti...

Abstract

The present invention discloses a medium thickness detecting device which comprises a reference roller (123), a thickness measuring roller (124) opposite to the reference roller (123), a detected element (131) which moves with the thickness measuring roller (124) synchronously, a first detection element (132) for detecting the detected element (131) and outputting a first electric signal, a second detection element (133) which is arranged at the second movement direction of the detected element (131) and outputs a second electric signal, and a control unit which detects the thickness of the medium between the reference roller (123) and the thickness measuring roller (124) through the first electric signal and the second electric signal. A medium transmission channel is formed between the reference roller (123) and the thickness measuring roller (124). Through the medium thickness detecting device, the accuracy of the medium thickness detection is improved.

Description

technical field [0001] The invention relates to the field of thickness detection, in particular to a medium thickness detection device. Background technique [0002] Sheet media processing devices such as ticket checking machines, banknote counting machines, and banknote sorting machines are equipped with a medium thickness detection device, which is used to judge whether there are problems such as sticking and double sheeting of sheet media such as ticket paper and banknotes. When the thickness of the sheet medium detected by the medium thickness detection device exceeds the predetermined thickness value of a single medium, it is determined that errors such as pasting and double sheeting have occurred. [0003] A banknote thickness detection device is provided in the prior art, such as figure 1 As shown, the detection device includes a lower thickness measuring roller 1' and an upper thickness measuring roller 2', the position of the upper thickness measuring roller 2' is ...
