Anti-light damage valuable document channel structure

Abstract

The invention relates to a light-pollution-preventing channel structure for a valuable document. The light-pollution-preventing channel structure comprises a main body and a receiving device positioned in the main body and internally provided with a channel communicated with a socket position of a main body plane. A seat body, internally corresponding to the channel position, of the receiving device is provided with control modules and transmission devices capable of driving the valuable document to move to recognizing devices. A sampling and recognizing module of each recognizing device is provided with multiple light-emitting bodies and light-receiving bodies. Light path control films are arranged between the channel and the light-receiving bodies and used for blocking light emitted from a non-light-emitting body to the light-receiving bodies in a light path to prevent misjudgment or incapability of recognition due to light of an external source emitted to the light-receiving bodies via the channel, thereby diminishing the influence of light pollution, enhancing the accuracy rate and stability of recognition and improving a light-pollution preventing effect.

Description

technical field [0001] The present invention provides an anti-light damage channel structure for valuable documents, especially the identification device corresponding to the channel inside the receiving device is located between the channel and the light receiving body, and an optical path control film is provided to control the non-light emitters on the light path. The light incident to the light receiver is blocked, which can prevent the light from the external light source from entering the light receiver through the channel, causing misjudgment or unrecognizable situations. Background technique [0002] Today's social civilization and high-tech development have not only accelerated the pace of people's lives, but also tend to demand more convenience and speed for the quality of life. Therefore, in many public places, in order to consider the convenience and timeliness that the public pays attention to, most of them will Setting up automatic vending machines, teller mach...

Problems solved by technology

[0005] However, the problem of light pollution when the valuable document receiver is used is becoming more and more serious, especially in the case of sunlight or lighting equipment with high brightness and high flicker frequency of signboards and advertising billboards, and the light will enter through the socket on the body panel. into the channel, and through the dust-proof sheet on the lens module, and then refracted by the lens group to the light source receiving element to produce light interference phenomenon, resulting in misjudgment or machine failure, malfunction, although the dust-proof sheet has wear resistance, anti- Dust and anti-fouling effects on the surface, but because the dust-proof sheet has no light path control function, all light can pass through the dust-proof sheet and refract to the light receiving element, which limits the effect of light pollution protection and affects the overall recognition accuracy, and cause significant economic losses to the operator, or withdraw the valuable document because it cannot be recognized. In this way, the user needs to insert the valuable document repeatedly, which is extremely inconvenient and troublesome in actual operation. The industry has redesigned to effectively address
