    Abstract: The control system is constituted by a plurality of switches operated by inserted coins of different denominations, first register for storing amounts of inserted coins for each denomination and a second register for storing remaining amount of change. The amount of coins corresponding to operated switch is added to the content of the first register, 1 is added to the content of the second register in accordance with the denomination of the inserted coin, and 1 is substracted from the content of the second register in accordance with the denomination of payed out money. The selling price of a merchandise is subtracted from the total price of the inserted coins for calculating the amount of change. Selling is possible or not is determined by sequentially subtracting the price of the coins starting from a coin of the highest price from the change. The content of the first register is sequentially changed until the content exceeds the selling price and the selling price is subtracted from the content of the first register for setting the content to the amount of change for different denomination of coins.

    Abstract: This bill accepting device comprises a bill discrimination section for discriminating whether an inserted bill is true or not, an escrow section capable of retaining a bill accepted by the bill discrimination section as a true bill and returning the retained bill, a stocker section for storing the bill accepted by the bill discrimination section as a true bill, and passage switching means for causing a bill passage in the bill discrimination section to communicate selectively either with the escrow section or with the stocker section. The passage switching section normally communicates the bill discrimination section with the escrow section to enable an inserted bill to be retained in the escrow section in a state in which the bill can be readily returned. When the escrow section has become full, the passage is switched so that the inserted bill is guided from the bill discrimination section to the stocker section.
