Coin stacking device

A coin stacking device comprising:

• a first wall member having an arcuately recessed curved surface rotatably supported on a first pivot shaft which is fixed in space;
• a second wall member having an arcuately recessed curved surface disposed contiguously to said curved surface of the first wall member to form therewith a continuous curved surface defining a substantially semicylindrical cavity, said second wall member being rotatably supported on the first pivot shaft and being biased to rotate about the first pivot point in the direction to widen the cavity;
• a support lever rotatably supported at one end thereof by a second pivot shaft fixed to an extended part of the first wall member and biased to rotate about the second pivot point in the direction to separate the other end thereof away from said cavity;
• a third wall member supported on said other end of the support lever, thereby being movable toward and away from said cavity, and having an arcuately recessed curved surface opposed to said cavity and forming therewith a continuous curved surface of substantially circular cross section which is of variable diameter and defines a cylindrical space for stacking of coins supplied thereinto;
• a regulating device provided on the support lever and functioning to determine the angular position of the second wall member relative to the first wall member thereby to determine the degree of opening of the cavity;
• and
• adjusting means adjustably operable to move the support arm thereby to adjustably vary the diameter of said cylindrical space to any selected one of a plurality of predetermined values corresponding to the diameters of different kinds of coins.
