Patent attributes
A dispenser shutter assembly of an automated teller machine and a method for preventing damage to the dispenser shutter assembly. The dispenser shutter assembly includes: a shutter; a shutter plate; cam followers attached to the shutter plate; a cam coupled to the cam followers; a motor that rotates the cam in a first rotational direction in a plane of rotation of the cam for inducing the cam to act on the cam followers to cause movement of the shutter plate to transition the shutter to a closed state of the shutter; and a cam rotation restrictor positioned so as to prevent rotation of the cam beyond an over center position on the cam's rotational axis by forcing the cam to rotate in a second rotational direction that is opposite the first rotational direction in response to a manual opening of the shutter from the closed state of the shutter.
