  • Patent number: 4749076
    Abstract: A bill accepting device judges whether a deposited bill is a true bill or not and produces a true bill signal if it is a true bill. A device such as a vending machine utilizing this bill accepting device receives this true bill signal, counts the number of the deposited bill and, upon confirming that the counting has been properly made, produces a true bill confirmation signal. The bill accepting device receives the true bill confirmation signal and thereby confirms that the true bill signal has been properly used. Thereupon, the bill accepting device stores the deposited bill. If this confirmation has not been made, the deposited bill is automatically returned notwithstanding that it is a true bill.

  • Patent number: 4706202
    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.

  • Patent number: 4556139
    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.

  • Patent number: 4347925
    Abstract: In the malfunction indication device for a vending machine according to this invention, a malfunction occurrence indicator is provided at a prominent place on the outside of the vending machine. This indicator indicates occurrence of malfunction immediately upon detection of the malfunction by a malfunction detector to give warning to a purchaser. Simultaneously, a code representing a detected malfunctioning point is stored in a memory circuit. By manipulation of an indication control switch by an operator, the code representing the malfunctioning point is read from this memory circuit and indicated by a malfunction code indicator. As the malfunction occurrence indicator and the malfunction code indicator, a money amount indicator already provided in the vending machine for indicating an amount of deposited coins or a balance thereof is advantageously utilized.
