This paper describes design conditions for the coin diameter-thickness checker mechanism. The relations between the dimensions of coin and those of the mechanism are analyzed in order to obtain the static condition to check coins surely, and the dynamic coin motion is analyzed in order to obtain the limitation of minimum length in this mechanism. The results obtained are as follows.<BR>(1) Large influence factors on diameter checker are round edge of coin, diameter gage height and truck width t0.<BR>(2) Large influence factors on thickness checker are t0 and thickness gage width.<BR>(3) The minimum length of coin checker mechanism l0 can be written by l0=δ·v0+d. Where v0 ; initial rolling speed of coin, δ; coefficient, d; coin diameter.<BR>(4) If we design l0 is equal to (1. 8-2. 0) × d, we can gain good characteristics of checker is the case of usual v0 =0. 3-0. 4 m/s.<BR>(5) The theoretical value in these results nearly fitted to the experimental value.
