TW200411582A - Detection device of coin receiver - Google Patents

Abstract

The present invention relates to a detection device of coin receiver, wherein a receiver is installed inside the panel. When the coin is dropped from the coin inlet of the panel, the coin slides from the coin-inputting channel of the receiver, and a magnetic field is generated in the printed circuit board having a spiral coil of the sensing device on both sides of the rail. The coin surface forms different magnitudes of eddy currents depending on the magnitude of permeability, so that the inductor value sensed by the printed circuit board having spiral coil layout is transmitted to a CPU, and it is compared with the internal preset value of CPU to further determine if whether the coin is real/feinted and the magnitude of the coin. By disposing the printed circuit board having spiral coil layout, it is able to increase the stability in determining the coin value, decrease the installation space of hardware , and achieve the purpose of having high recognition rate of coin reducing space and having less damage .

The livelihood of the stakeholders and the rights and interests of consumers are related to the financial order of the society. However, most of them currently use pot-shaped core coils as magnetic components of metal coins. Metal materials are classified as strong magnets (such as (Iron, copper, nickel, etc.) and weak magnetic 胄 (such as Ming, 铭, etc.). The magnetic induction method is to generate an oscillation frequency after the coil is turned on, and then form a magnetic field that can sense coins made of various metal materials, and coins The increased permeability of the material will cause the eddy current generated by the magnetic field to change. Therefore, if coins of different metal materials pass through the coil at a certain oscillation frequency, the inductance value will change to different degrees. Generally, The inductance error value in the characteristics of the shaped iron core coil is about 5 1 〇 / ', and the sub shaped iron core coil is prone to chipping or the temperature changes H to make the inductance value error. How to change the deficiency and absence of the pot shaped iron core coil' The key to this change is to engage in this industry. Therefore, only by improving the accuracy and stability of coin identification can counterfeit coins not be confused, and Livelihood of interest industry and consumer demand is guaranteed; Furthermore 'ships still pot core coils having a greater volume and deletion of poor flatness
