PROBLEM TO BE SOLVED: To surely prevent a crime in which real coins corresponding to the amount of misunderstood coins are deceivingly acquired by comparing operation history up to that time with a preliminarily set illegal pattern and deciding it as illegal when a prescribed relation is established between them when purchase cancel is detected.;SOLUTION: When a cancel button is pressed down to cancel product purchase after the amount of inputted coins reaches the price of a product to be purchased, a main controlling part 11 recognizes that the cancel button is pressed down and checks whether or not coins inputted this time are specific coins that are frequently forged and altered. When they are the specific coins as a result of the check, the part 11 compares an illegal operation pattern stored in a data storing part 12 with operation history. When the operation history coincides with the illegal operation pattern as a result of the comparison, it refers to the inputted denomination of the operation history coinciding with the illegal operation pattern and the inputted denomination that is canceled this time, and when the same denomination exists, it decides synthetic decision as 'illegal'.;COPYRIGHT: (C)2000,JPO
