Filed: 2017-02-07
Abstract: PROBLEM TO BE SOLVED: To improve work efficiency of a game house-closing operation while preventing frauds in the game house-closing operation when an each-machine counting method is employed.SOLUTION: In an inter-machine device, a counting unit counts game media acquired by a player in a game machine corresponding to the inter-machine device, a storage unit stores the counted count, and upon receiving an issue instruction, a card issue processing unit issues a count recording medium after the read count is associated with the count recording medium as a processed count. Upon an instruction receiving unit receiving a notification instruction, an unprocessed count notification unit forbids an issue instruction to the card issue processing unit and then reads an unassociated count from the storage unit to notify a management device thereof as an unprocessed count. The management device forms a count management system such that an instruction notification unit sends the inter-machine device a notification instruction and such that the count storage unit stores the unprocessed count in an unprocessed count storage unit in association with the inter-machine device that notifies the unprocessed count.SELECTED DRAWING: Figure 3
