(57) A coin handling mechanism for vending machines is disclosed which includes a control
portion. The control portion always counts the number of each deposited denomination
coins which is outputted from or inputted into each change retaining tubes according
to the results of paying out of a coin return mechanism, output signals of a coin
validation sensor and output signals of overflow sensors. Accordingly, when the sales
are collected, if the number of the coins which should be retained in change retaining
tubes is not changed, the increment of the coins retined in change retaining tubes
is automatically paid out by turning switches "OFF" and "H" of the inventory switch
on. Simultaneously, with respect to the decrement of the coins retained in change
retaining tubes, since the denomination of the coins corresponding to the decrement
is indicated by an indication portion, respectively, the decrement is solved by depositing
the denomination coins corresponding to the indication to each change retaining tubes
through an coin inlet until the indication is disappeared, and thereby to make the
operation of supplying coins to change retaining tubes be easy.
