Vacuum crane arcade game
Abstract:
An arcade target game uses an extendable extraction device to enter a tube of cards in a horizontal direction. The prizes are protected by the tube's outer wall that limits successful attempts to those tries that avoid the wall. A vacuum source allows the extraction device to capture the prize if the extraction device successfully enters the tube. The extraction device's effective radius can be adjusted by extending projections that reduce the tolerance between the disk and the tube's outer wall.
