ABSTRACT:
The invention provides a method of determining completion of coin insertion capable of easily and reliably determining whether or not a number of coins required for purchasing an article has been inserted. A coin holding portion (105) is constructed such that coins are retained in row in the coin holding portion (105) being electrically connected to each other in series. Further, a first electrode (121) that comes into contact with the coin located at one end side of the row is provided in the coin holding portion (105); and a second electrode (123) that comes into contact with the coin located at the other end side of the row is provided in the coin holding portion (105). The coin holding portion (105) is constructed to detect an electric current between the first electrode (121) and the second electrode (123) to determine whether or not the required number of coins has been inserted.
