Abstract
The present invention relates to a detection device for coin receiver. Inner side of panel is equipped with a receiver, when the coin is fed from panel slot, the coin can be slided into the receiver by means of coin-feeding channel, and when the coni is passed through induction devices respectively positioned at two sdies of guideway, the printed circuit board with volute coil can produce a magnetic field, and on the surface of the coin an eddy current which can have different intensities according to magnetoconductive coefficient can be formed, and the induction value induced by printed circuit board with volute coil arrangement can be transferred into a central processor, and can be compared with preset value so as to can identify real coin or false coin and can judge the coin value.
Description
Technical field
The present invention relates to a kind of arrangement for detecting of Coin acceptor.
Background technology
All set up the Coin acceptor that to judge the value of money that inserts coin and the true and false on automatic vending machine now, electronic toy, the Game device.And the correctness of Coin acceptor when the value of money of judging coin and the true and false, dealer's the livelihood that really concerns and consumer's rights and interests, and be related to social financial order.Yet, the dealer utilizes the pot core coil to make the Magnetosensing element of metal coin mostly at present, now divide into kicker magnet (as iron, copper, nickel etc.) and weak magnet (as aluminium, lead etc.) because of metal material, its sense magnetism method is can produce an oscillation frequency after the coil conducting, and then forms one and can respond to the magnetic field that various metal materials are made coin.And the vortex flow that the magnetic capacity number of coin material can make magnetic field produce changes, so if any the coin of different metal materials during by coil, its inductance value just can produce variation in various degree under certain oscillation frequency.And the inductance value error amount in the general pot core coil characteristics is about 5-10%, and the pot core coil is easy to generate cracked or is subjected to temperature variation and makes inductance value produce error, to how to change the deficiency and the disappearance of pot core coil, just for being engaged in the key point that the industry is desired most ardently change.Be with, accuracy and stability when having raising to the coin identification only can make counterfeit money get by under false pretences, and dealer's livelihood and consumer's rights and interests are protected.Moreover general pot core coil still has volume and reaches the not good disappearance of flatness more greatly, if can change formed bottleneck on these component shapes simultaneously, must effectively improve the disappearance on the conventional art.
Because the above-mentioned disappearance of commonly using is with not enough, be to collect related data, via assessing in many ways and considering, the side is to be engaged in research and development experience for many years, after continuous design, design and repeatedly revising, finally the development and Design patent of invention that goes out a kind of arrangement for detecting of brand-new Coin acceptor is born, the disappearance of the prior art that enables to forgo.
Summary of the invention
The present invention be directed to the above-mentioned deficiency of prior art, reduce in the space and the arrangement for detecting of non-damageable Coin acceptor and provide a kind of and improve the coin discrimination power, be provided with.
The technical scheme of the arrangement for detecting of Coin acceptor provided by the present invention is as follows:
A kind of arrangement for detecting of Coin acceptor, include the receiver at panel and panel rear, and the coin mouth of going into of panel is the track that is communicated in receiver, and the track place is the oscillatory circuit that is provided with induction installation, this oscillatory circuit is for carrying out the inductance value detecting to coin, and the preset value of central processing unit is done a comparison in inductance value after will detecting and the frequency switching circuit, and then judges the true and false and the value of money size of the coin that drops into; It is characterized in that:
Be to have the printed circuit board (PCB) of laying the volute coil in this oscillatory circuit, and printed circuit board (PCB) is two side wall surfaces that are positioned at the receiver track, and the volute coil on two printed circuit board (PCB)s is set up for being corresponding.
Except that the rising essential features, in specific implementation process, also can replenish following technology contents:
