一种硬币接收及分配机，包含有一硬币接收及分配口，一传感单元，设置在一硬币信道内，可供判断并计算每种面额的硬币，单一个硬币储放箱，用以储放可接受硬币，一个硬币储放筒，用以储放要分配之硬币，以及一控制器，用以控制硬币接收及分配机整体的运作，该控制器系构造成可在分配硬币之前，先将储放在硬币储放箱内的硬币取出、使传感单元判断并计算自硬币储放箱内取出的每种面额之硬币、并针对每一种面额将预定数量的硬币储放在硬币储放筒内，该控制设备系进一步构造成，在要分配硬币时，能将储放在硬币储放筒内的硬币取出、使传感单元针对每种面额判断并计算自硬币储放筒内取出之硬币、并根据传感单元所为的判断及计数结果，将硬币送入硬币接收及分配口内，该控制设备更进一步构造成，可使得传感单元来判断经由硬币接收及分配口投入的硬币是否为可接受者，及硬币的面额，以及计算每种面额的硬币数目，并将经由硬币接收及分配口投入的硬币储放至硬币储放箱内。

A coin receiving and dispensing machine includes a coin receiving and dispensing opening, a sensor unit provided in a coin passage and adapted for discriminating and counting coins of each denomination, a single coin storing box for storing acceptable coins, a coin storing cylinder for storing coins to be dispensed and a controller for controlling overall operation of the coin receiving and dispensing machine, and the controller is constituted so as to, prior to dispensation of coins, take out coins stored in the coin storing box, cause the sensor unit to discriminate and counts coins for each denomination taken out from the coin storing box, and store a predetermined number of coins in the coin storing cylinder for each denomination, the controller being further constituted so as to, when coins are to be dispensed, take out coins stored in the coin storing cylinder, cause the sensor unit to discriminate and count coins taken out from the coin storing cylinder for each denomination, and feed the coins to the coin receiving and dispensing opening based on the discrimination and counting done by the sensor unit, the controller furthermore being constituted so as to cause the sensor unit to discriminate whether or not coins deposited through the coin receiving and dispensing opening are acceptable and denominations of coins and count the number of the coins of each denomination, and store the coins deposited through the coin receiving and dispensing opening in the coin storing box.
