of fig2 detects another coin e g 100 yen a sensor 500s near the sensor 100s detects the another coin e g 500 yen similarly symbol 5s shown in the path board 33 of the lower part of fig2 is a sensor for detecting another coin e g sensor 5s will output a signal if a 5 yen coin is detected a sensor 50s near the sensor 5s detects another coin e g a 50 yen coin similarly in addition the upper surfaces of each sensor 1s 500s are arranged to be coincident with the upper surface level of the path board 33 as shown in fig4 in other words each sensor is arranged so that coins can pass smoothly over the ring shape path board 33 fig2 shows on the path board 33 of the down stream side of each sensor 1s 500s an oblong open hole h through which each coin can drop respectively further these oblong open holes h are respectively formed of the same shape still an opening ch which is provided at the most downstream of path board 33 is formed in order to store coins or cancel coins and near the inside edge in each oblong open hole h a long and slender gate g is pivotably openable respectively see fig2 in addition the gate g is specifically a long and slender roller which is rotatably arranged moreover the upper surface of each gate g is arranged to be coincident with the upper surface level of path board 33 as shown in fig5 that is each gate g is arranged so that the coin can pass the ring shape path board 33 smoothly as shown in fig5 and on the base board 31 near the outside edge in each open hole h.
