PROBLEM TO BE SOLVED: To provide respective machine counting units which are allowed to prevent the number of game media counted in a counting section from being lost even when a ball lending ticket issuing section storing the number of the game media fails or abnormal condition occurs in the data on the number of the game media. SOLUTION: The counting section of a restoration origin updates a stored first storage value on the basis of counting of the game media, and the ball lending ticket issuing section of a restoration destination also updates a stored second storage value on the basis of counting information transmitted from the counting section. When the power of the ball lending ticket issuing section and the counting section is supplied (S300), the ball lending ticket issuance control section 22 of the ball lending ticket issuing section determines whether or not a restoration condition is established, and performs restoration processing (S333) of storing the first storage value as the second storage value on condition that it is determined that the restoration condition is established (NO in S311, NO in S321, or NO in S331).
