Abstract: A display device which can mechanically and cumulatively count and display the amount of money for coins. The use of coins having a random relation between nominal values and diameters is possible by the provision of operation members. The operation members include carry operation members, each of the operation members has a corresponding digit display wheel which shows the cumulative amount of money. A coin inlet and guide member has pushing members for pushing a suitable operation member without pushing other operation members. To this end, the operation member other than the carry operation member each has at least one groove with a reception surface to which the pushing member abuts for pushing the operation member and an idle groove which is not actuated by another of the pushing members if it is guided into the idle groove. The idle groove serves as eliminating the problem of the random relation between nominal values and diameters of the coins.
