There is a technique disclosed in Publication No. 221777. This applies an alternating magnetic field to the detection coil, and the detection coil is arranged so that the area of the overlapping portion when facing a coin varies depending on the coin diameter. With this configuration, the alternating magnetic field induced by the detection coil is influenced by the outer diameter of the coin as it passes, and the detection coil outputs a measurement signal of the outer diameter.

レールが長くなつて装置が大型化する。(c) Problems that the invention aims to solve In such a coin diameter inspection device, when a coin passes through the detection coil while bouncing in the vertical direction, the area of the overlap between the coin and the detection coil varies, making it difficult to accurately measure the diameter of the coin. Measuring the coin diameter becomes difficult. Therefore, in the case of conventional coin diameter inspection devices, since the coin inserted from the coin input port bounces when it lands on the coin rail, the coin is rolled for a while and the coin is placed in a state where the bouncing has calmed down. Measuring the diameter. Therefore, in the conventional device, the coin rail becomes long and the device becomes large.

will be subject to measurement. Since the state in which the coin is supported by the cradle 5 becomes deeper or shallower depending on the outer diameter of the coin, the area of the portion overlapping with the detection coil 5 varies greatly accordingly. Therefore, the detection coil 5 can amplify and capture the outer diameter of the coin.

り、硬貨径を精度良く測定できる。(F) Embodiment The figure shows a coin sorting device 20 equipped with a coin diameter inspection device according to the present invention, and the coin diameter inspection device includes a cradle 2 that receives and swings coins inserted from a coin slot 1; , and a detection coil 5 as a measuring device. The cradle 2 includes a pair of locking pins 3 and 4 for supporting coins, and usually has a weight 6.
The locking pins 3 and 4 are forced to face the coin slot 1. When a coin is supported, it rotates clockwise due to its weight and guides the coin to the coin rail 6. The detection coil 5 induces an alternating magnetic field and measures the degree of influence on the magnetic field by a coin supported by the cradle 2 and swinging, and is installed at a position where it only partially faces the coin. When the detection coil 5 is arranged in this way, a coin 8 with a large outer diameter has a larger area of the portion overlapping with the detection coil 5 than a coin 9 with a small outer diameter, and the degree of influence on the magnetic field increases accordingly. The detection coil 5 detects when a coin passes due to the rocking of the cradle 2.
The outer diameter is measured by detecting the oscillation frequency and inductance. In addition, the distance between the locking pins 3 and 4 is set to be smaller than the outer diameter of the smallest coin.
As a result, the coin 8 having a large outer diameter is supported by the cradle 2 shallowly, so that it comes closer to the detection coil 5, and the area of the mutually overlapping portion becomes larger. On the other hand, since the coin 9 with a smaller outer diameter is supported more deeply by the cradle 2, the area of the overlapping portion away from the detection coil 5 becomes smaller. Therefore, the outer diameter of the coin supported by the cradle 2 is amplified and measured by the detection coil 5, and the coin diameter can be measured with high accuracy.

できる。 After the rocking of the cradle 2 is completed, the coin introduced into the coin rail 7 is transferred to the return passage 13 or the receiving passage 12 by the action of the coin gate 11 that protrudes and retracts from the base plate 10 according to the measurement result of the outer diameter. be introduced. Further, in the coin sorting device 20, a sensor 14 for measuring the material of the coin and a sensor 15 for measuring the thickness of the coin are arranged on the coin rail 7 as needed, and a comprehensive evaluation with the coin diameter inspection device according to the present invention is carried out. Coin gate 1 determines the authenticity and type of coins.
1 allows you to sort coins. Furthermore, although the measuring device of this example measures magnetically by forming an alternating magnetic field in the detection coil 5, a configuration in which a plurality of optical sensors each consisting of a pair of light emitting elements and light receiving elements are arranged can also be used. It is possible to measure the outer diameter of a coin that is supported by and swings. in this case,
For example, the outer diameter can be measured by determining how many of the plurality of optical sensors are blocked from transmitting and receiving light by the swinging coin.

定が期待される。 In this way, the coin diameter measuring device which combines the cradle 2 and the detection coil 5 which is a measuring device is designed to operate the detection coil 5 while swinging the coin in the cradle 2.
The outer diameter of the coin is measured at Therefore, since the kinetic energy of the coin is absorbed by the cradle 2, the outer diameter of the coin can always be measured by the detection coil 5 under the same conditions regardless of the inserted state, improving accuracy. Since rocking by the cradle 2 and measurement by the detection coil 5 are performed simultaneously, the detection coil 5 can be placed close to the coin slot 1. Moreover, since the kinetic energy of the coin whose outer diameter has been measured has been absorbed, the coin gate 1
If the other sensors 14 and 15 are placed next to the coin diameter measuring device, highly accurate measurements can be expected with these sensors 14 and 15.

Since the supporting position of the cradle is changed according to the outer diameter of the coin, the difference in outer diameter between the coins is amplified and inspection can be performed with high accuracy.
