Ball Lifter ( bingo )

The mechanism used to raise the ball from beneath the playfield to the ball shooter tip.
Manual: A plunger below the ball shooter can be pushed in at any time to raise a ball for play.
Automatic: A motor raises the ball when appropriate. On most games, a ball is raised as soon as the current ball leaves
the ball gate. Some later games actually detect when a ball has fallen into a hole, and raise the next ball then.
