Abstract: The invention proposes an insertion device for coins for transferring said coins to a coin tester or to a coin-operated machine, having an insertion slot and having a coin outlet, between which is arranged a rotatable drum having a receiving region for receiving a coin, wherein in a receiving position, the receiving region is accessible to a coin which can be inserted through the insertion slot, and the insertion slot can be closed off by means of rotation of the drum. The drum having the receiving region is covered by a flap which can be opened in a controlled fashion in an ejection position for ejecting foreign material.

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.
