    • In a vending machine for which both money and a prepaid card can be used, a writing-instruction switch is provided for controlling of amount information into the card. When the writing-instruction switch has been actuated, the amount of inserted money and the credited value of the card are added up and the sum is written into the card for renewing its credited value. In this manner, it becomes possible to additionally renew the amount recorded in the prepaid card. Further, an amount selector may be provided for selecting an amount to be added to a prepaid card. On condition that money of an amount not smaller than the amount selected by the amount selector has been inserted, the selected amount and the recorded amount of the card are added up for renewing the recorded amount of the card. Thus, it becomes possible to write a desired amount into an already issued prepaid card.
    • 在可以使用货币和预付卡的自动售货机中,提供写入指令开关用于控制卡内的金额信息。 当写指令开关被启动时,插入的金额和卡的信用值相加,并且将该金额写入卡中以更新其信用值。 以这种方式,可以另外更新记录在预付卡中的金额。 此外,可以提供量选择器,用于选择要添加到预付卡的数量。 如果金额不小于由金额选择器选择的金额已经被插入的金额,则将所选择的金额和卡的记录金额相加,以更新卡的记录金额。 因此,可以将所需的量写入已发行的预付卡中。

    • 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.
    • 控制系统由多个由不同面额的插入硬币操作的开关构成,第一寄存器用于存储用于每个面额的插入硬币的数量,以及用于存储剩余的变化量的第二寄存器。 将与操作开关相对应的硬币的数量加到第一寄存器的内容中,根据所插入的硬币的面额将1加到第二寄存器的内容中,并且从第二寄存器的内容中减去1 按照支付的货币的面额。 从用于计算变化量的插入硬币的总价中减去商品的销售价格。 销售是否可以通过从更改中逐渐减去从最高价格的硬币开始的硬币的价格来确定。 第一寄存器的内容被顺序地改变,直到内容超过销售价格,并且从第一寄存器的内容中减去销售价格,用于将内容设置为不同币种币种的变化量。
