〔発明の実施例〕[Embodiments of the invention]

以下本発明の実施例を図面を参照して説明する。 Embodiments of the present invention will be described below with reference to the drawings.

る第１の選別部である。FIG. 1 shows the configuration of a sorting system of an example of the sorting apparatus of the present invention, and in the figure, 1 indicates coins to be discriminated and sorted. 2 is the coin's outer diameter, thickness, influence of magnetic field, and collision repulsion. This is a first sorting section that determines whether the coin 1 is genuine or false based on the amount, etc., and also determines the denomination.

収部６に回収されろ。The first sorting section 2 sorts out the coins 1 by denomination according to the above-mentioned discrimination conditions, and also discriminates between fake coins and altered coins. For example, coins sorted by denomination such as 10 yen and 100 yen are stored in the respective denomination safes 38 to 3E. Further, the altered coins are collected by the collection unit 4. At least one type of coins selected by the first sorting section is further subjected to authenticity determination by the second sorting section 5. This second sorting s5 is to sort out coins having the same size and material as domestic coins, such as foreign coins, for example. The counterfeit coins identified by the second sorting section 5 are collected by the collection section 6.

振動数が異なる点を利用しているものである。The configuration of the second sorting section 5 mentioned above will be explained with reference to FIG. In the figure, 7 is a coin entrance passage leading to the first sorting section 2, 8 is a collision partner member disposed below the entrance passage 7, and 9
1 is a space chamber for freely moving the coin 1 that has collided with the collision partner member 8; 10 is a passageway for guiding the fake coins to the collecting section 6 shown in FIG. 1; and 11 is a space for storing genuine coins in the safe 3D or 3E. 12 is a gate for switching between the passages 10 and 11; 13 is a gate switching means; -14 is a vibration detection means for detecting the vibration of the coin 1 freely vibrating within the space chamber 9; I can do it. 15
is a discrimination section that compares the vibration frequency of the coin 1 to be discriminated from the vibration detection means 14 with a pre-stored number of images of a coin of a certain denomination to discriminate its authenticity. When the discrimination section 15 determines that the coin to be discriminated is a fake coin, it outputs a gate operation signal to the Goo 4 switching means 13. The discrimination section described above utilizes the fact that even coins of the same size and material have different frequencies depending on the pattern on the coin surface.

収納される。When the coin 1 to be distinguished is put into the first sorting section 2, the first sorting section 2 examines the outer diameter and thickness of the coin, the influence of the ffl field,
Based on conditions such as the amount of fjf1 sudden rebound, the authenticity is determined and the denomination is determined. Coins determined to be fake coins are collected by the collection unit 4. On the other hand, coins that are determined to be genuine coins and whose denominations are determined are stored in safes 3A to 3E corresponding to each denomination. Among the coins of each denomination stored in the safes 38 to 3E, coins of the denominations including coins of the same size and material such as foreign coins are processed by the second sorting section 5.
will be put into the This second sorting section 5 compares the frequency of the coin with the frequency of hardening of a certain denomination stored in advance.
Determine whether it is true or false. Based on this determination, fake coins are identified by the collection unit 6.
Collected real coins are stored in the respective safes 3D or 3E.
