ABSTRACT:
Disclosed is a comparative type detector for a coin-collecting mechanism. The comparative type detector includes a movable slot way portion having parallelly arranged and downward open first and second slot ways, as well as a main slide way and a secondary slide way located below and aligned with the first and the second slot ways, respectively. The second slot way and the secondary slide way together define a space for positioning a sample coin therein, and the first slot way and the main slide way together define a passage for a coin inserted into the coin-collecting mechanism to pass therethrough. Electric eyes are fixedly mounted at front and rear ends of the first slot way respectively slightly higher and lower than a reference line which is defined by a line parallel to a bottom surface of the secondary slide way and tangent to a top point of the sample coin. The distance between the electric eyes and the reference line determines the tolerance in examining diametrical size of an inserted coin compared to the sample coin.
