Description

  The present invention relates to a structure of a coin processing device, and more particularly to a structure of a coin processing device that is easy to assemble.

  Modern vending machines, electric toys, and game machines are all provided with a coin processing device that can determine the face value and authenticity of the coins that have been inserted. The accuracy of determining the face value and authenticity of coins in coin handling equipment is important for the survival of merchants and the protection of consumer interests, and also for maintaining the financial order in society. At present, many of the contractors manufacture a magnetic sensing element of a metal coin using a saddle-shaped core coil. Metal materials are classified into strong magnetic materials (such as iron, copper and nickel) and weak magnetic materials (such as aluminum and lead). In the magnetic sensing method, after a coil is conducted, a resonance frequency is generated, and a magnetic field capable of sensing coins manufactured from various metal materials is formed. Since the eddy current generated by the magnetic field changes due to the difference in the magnetic permeability of the coin material, when a coin of a different metal material passes through the coil under a predetermined frequency resonance, the inductance value changes to a different extent. Generally, the error value of the inductance amount of the saddle-shaped core coil is 5 to 10%. Further, the saddle-shaped core coil is damaged, or an error occurs in the inductance value due to a temperature change.

  A criminal studies the characteristics and structure of a coin processing device, drills a coin, passes a transparent, hard-to-cut thread through the hole in the coin, puts the coin into the coin processing device, and the coin processing device inserts the coin. After sensing, the inserted coin is pulled out by pulling the thread to the upper side of the magnetic sensing element, the thread is loosened again to pass through the magnetic sensing element, and the above operation is repeated to cheat the inserted amount. If fraud occurs as described above and the amount of damage is large, the contractor must remove the vending machine, electric toy or game device that has been fraudulently from the viewpoint of cost, and the normal consumer For them, convenience is lost by removing them.

As mentioned above, the coin processing apparatus according to the prior art has many problems and drawbacks, how to prevent criminals from fraudulently investing money and protect the rights and interests of merchants and consumers. It was a problem that the inventor of the present invention and those skilled in the art wanted to improve.
