Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This application relates to a coin return mechanism in a coin holding and dispensing device used in public telephones, vending machines, and the like.

Conventional technology Conventionally, coin holding and dispensing devices used in public telephones or vending machines use a magnetic sensor to determine whether the coins inserted through the coin slot are genuine or false, and distinguish between genuine coins and counterfeit coins. a diameter sorting mechanism that sorts the diameter of the inserted coins and guides the coins to different passages depending on their diameter; and a diameter sorting mechanism that sorts the coins into different passages depending on their diameter, and discharges fraudulent coins held in the passage to the return passage by opening the coins. a coin sorting device comprising a coin discharging mechanism; a coin holding section that receives the coins sorted by the coin sorting device and holds a plurality of coins according to the size of the diameter, that is, of all types; a dispensing mechanism for dispensing coins held in the holding section into a coin storage passage according to the frequency of use;
It consists of a coin return mechanism that guides all the remaining coins held in the coin holding section after use to a return passage, and the coin return mechanism is, for example, a tiltable hook for hanging the handset of a public telephone. In addition, in vending machines, these were linked to manual return levers.

Problem to be Solved by the Invention However, according to the conventional coin holding and dispensing device described above, when returning the remaining held coins, the coin return mechanism must be operated against the total weight of the remaining coins held in the coin holding section. Therefore, when the coin return mechanism is linked with the telephone hook, the operating load of the coin return mechanism must be lighter than the weight of the handset. It is necessary to reduce the weight of the mechanism or weaken the return elasticity of the coin return mechanism.

However, if the coin return mechanism is made lighter or its return elasticity is made weaker, there is a risk that the return operation will become unstable and that all remaining held coins may not be returned or coins may jam. Therefore, mechanical design to eliminate this concern was also troublesome. The above-mentioned fear in public telephones is also caused by insufficient manual operation of the return lever when the coin return mechanism is linked to the return lever in a vending machine.

Means for Solving the Problems Therefore, in order to improve the above-mentioned disadvantages of the conventional ones, the present application proposes a coin sorting device that sorts input coins, and a system that receives coins sorted by this coin sorting device and holds a plurality of coins. a coin storage section, a return path that is continuous with the coin storage section and leads the stored coins to a return port, and normally protrudes in a position continuous with the coin storage section and the return path to maintain a stored state of the coins;
