Validation circuitry enables a patron to use a wireless device to purchase gaming credit at a gaming machine. The wireless device transmits a touchpoint ID for the gaming machine to the transaction server, which communicates with a gaming system server to create a voucher for the gaming credit and wirelessly transmits a transaction package for the purchased gaming credit to the wireless device, wherein the transaction package includes the voucher ID. The wireless device wirelessly transmits at least the voucher ID to the validation circuitry, which transmits at least the voucher ID to the gaming system server to redeem the voucher. The gaming system server transmits gaming-credit approval to the validation circuitry. The transmissions between the validation circuitry and the gaming system server are independent of the game controller. The validation circuitry transmits the gaming-credit approval to the game controller, which provides the gaming credit to play the gaming machine.

There is provided a coin handling apparatus capable of reducing the occurrence of failure caused by a foreign material. A coin handling apparatus includes a coin inlet unit into which coins are put, a coin receiving unit that receives the coins put into the coin inlet unit, a coin discharge unit to which the coins are discharged, and a foreign material discharge chute which is connected to the coin inlet unit and the coin discharge unit and along which a foreign material put into the coin inlet unit is discharged to the coin discharge unit.

The present invention includes an opening/closing member, a rotary member that rotates integrally with the opening/closing member, a driving member for opening/closing member driving, that is arranged to oppose the rotary member and that is axially supported to be capable of relatively rotating with respect to the rotary member, and a drive transmission mechanism that transmits a drive force from the driving member to the rotary member, in which the drive transmission mechanism includes a driven piece, and a driving piece that rotationally drives the rotary member by pressing the driven piece, and a value of a circumferential backlash (3) between the driven piece and the driving piece is set to a value that enables prevention of the opening/closing member from being rotated to transition to the initial rotational posture by an operation from outside while the opening/closing member is stopped in the non-initial rotational posture.
