一种硬币包卷机，其包含一辨识器，其系用以辨识硬币是否为可接受硬币，且当硬币为可接受硬币时，其便辨识该硬币之面额，且辨识该硬币面额是否与指定之面额相符，并且计算该具有指定面额之硬币的数量，且包含一硬币堆栈设备，其系用以堆栈具有欲包卷面额之硬币，且包含一参考硬币堆高度数据内存，其系用以存储由该硬币堆栈设备所堆栈之每一种面额之硬币的参考硬币堆高度数据，且包含一硬币数量差异侦测设备，其包括一比较器，该比较器系用以将一硬币堆高度与存储在参考硬币堆高度数据内存中之每一种面额之参考硬币堆高度数据相比较，且该辨识器之设计系相应于具有指定面额之新发行硬币及旧流通硬币之集合，以辨识出每一硬币系新发行硬币或是旧流通硬币，且该硬币数量差异侦测设备之设计系相应于具有指定面额之新发行硬币及旧流通硬币之集合，以使其比较器可以依照由该辨识器所计数出来之新发行硬币数量及旧流通硬币数量，而选择出可以与由该硬币堆栈设备所堆栈之硬币堆高度相比较之参考硬币堆高度数据。如此构成之硬币包卷机系可以在具有欲包卷面额之新发行硬币及旧流通硬币欲包卷在一起的情况下，精确地侦测该欲包卷之硬币数量是否多于或少于一预定数量。

A coin wrapping machine includes a discriminator for discriminating whether or not a coin is acceptable, a denomination of the coin when the coin is acceptable and whether or not the denomination of the coin coincides with that specified and counting coins of the specified denomination, a coin stacking device for stacking coins of the denomination to be wrapped, a reference stacked coin height data memory for storing reference stacked coin height data for each denomination of coins stacked by the coin stacking device, and a coin number discrepancy detecting device including a comparator for comparing a height of stacked coins and the reference stacked coin height data for each denomination stored in the reference stacked coin height data memory, the discriminator being made responsive to inclusion in coins of the specified denomination of new issue coins and past issue circulating coins for discriminating whether each coin is a new issue coin or a past issue circulating coin, and the coin number and discrepancy detecting device being made responsive to inclusion in the coins of the specified denomination of new issue coins and past issue circulating coins for causing the comparator thereof to select the reference stacked coin height to be compared with the height of coins stacked by the coin stacking device in accordance with the number of the new issue coins and the number of the past issue circulating coins determined based on a count made by the discriminator. The thus constituted coin wrapping machine can accurately detect whether the number of coins to be wrapped is more than or less than a predetermined number even in the case where new issue coins and past issue circulating coins of the same denomination are wrapped together.
