SOLUTION: A game medium lending processor (card unit) 3 with an accepting part for notes, data memory medium, etc., is equipped in parallel with each Pachinko machine 2. The card unit 3 is equipped with an accepting part and the control part of a card reader/writer inside and connected with a group management device 1a with a coin storage part 8 on one side of the island facility 1, a card storage 11, etc., by a card recovery conveyor, etc. The control part reads/writes accepted data in the accepted data memory medium and subtracts within the range of data and stores data inside.
