ABSTRACT:
A lock provides a locking function after the insertion of a coin into it. The lock includes a punch card scanner which serves to enable the lock to provide the locking function. The lock includes a moveable bolt which is responsive to the scanner and a detent-like blocking catch. Movement of the bolt toward a locked position urges an inserted coin to lift the blocking catch, thereby freeing the bolt for further movement.
