Problems solved by technology

[0004] However, it is measured by the thickness sensors arranged in a row. Since the thickness sensors are too close to each other, there will be mutual interference, so a certain gap should be reserved between each thickness sensor. In passing, these thickness sensors cannot detect abnormalities, resulting in detection blind spots

Abstract

The embodiment of the present invention discloses a thickness detection device, which is used to prevent abnormal features such as foreign objects and damaged holes from passing through the gap, so that the thickness detection device does not have a detection blind zone. A thickness detection device in an embodiment of the present invention includes: a plurality of thickness sensors divided into two rows in the forward direction of the sheet medium, with staggered distribution between the two rows, so that any point on the sheet medium is in the Passing through the sensing coverage of the thickness sensor in the forward direction.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a thickness detection device. Background technique [0002] With the diversification of people's lives, the thickness detection of sheet media has gradually begun to be applied, and the application fields are becoming wider and wider. For example, ATM machines or banknote sorting machines in the commercial field need to detect the thickness of banknotes, so as to identify whether the banknotes are damaged, pasted with foreign objects, torn, etc., and can also use the thickness of banknotes as a standard for distinguishing authenticity. one. [0003] At present, the general method for detecting the thickness of sheet media is to combine the signals detected by multiple independent thickness sensors arranged in a row into the thickness characteristics of the entire banknote, so as to identify whether the banknote is abnormal. [0004] However, it is measured by the thickness sensors ar...
