A pinball elevator has an inclined conveyor belt tensioned between two pulleys and driven by an electric motor. The belt is perforated with a series of spaced circular apertures for receiving the pinball. Preferably, the apertures have a diameter of about 80% of the diameter of the pinball. A lower one of the pulleys is rotatably mounted beneath the playfield of the pinball machine, and an upper one of the pulleys is rotatably mounted above the playfield. The ball is received by the belt at an entrance location, and is ejected from the belt at an exit location. The ball passes above and over the upper pulley when being conveyed by the belt from the entrance location to the exit location. The upper pulley has a concave central region to prevent the pinball from being prematurely ejected from the belt by the upper pulley. At the entrance location, the pinball sits on the belt and abuts against a wall of the playfield. At the exit location, the ball is tangent to the belt around the upper pulley and is tangent to a supporting surface of an elevated exit ramp.

A pinball machine has a plurality of ball-deflecting components mounted to a playfield section. The playfield section is selectively translated in response to player input, so that the ball is deflected by the ball-deflecting components to locations selected by the player. The translation of the playfield section, for example, is responsive to the conventional push-button switches that are operated by the player for activating flippers, and in this case the push-buttons activate respective solenoids for translating the playfield section in two different directions. The playfield section, however, could be translated in different directions along two or three orthogonal axes in response to a more complex player-input device such as a joy-stick. In a specific embodiment, the ball-deflecting components define different sloping lanes on the playfield section, and the player operates the flipper push-button switches to translate the playfield section from side-to-side in order to bump the ball from one lane to another. A microcomputer is responsive to ball-sensing switches on the playfield section, and awards the player for lane changes.

A flipper in a pinball machine is rotated by a motor, permitting control of the angular position or velocity of the flipper by the pinball machine in response to player input, ball position or game sequences. The flipper is controlled internally through software of the microcomputer that keeps track of game sequences and the player's score, or externally via a switch or control manipulated by the player. Preferably the angular position of the flipper is sensed, and the motor can rotate the flipper in both a clockwise and a counter-clockwise direction. In one embodiment, the flipper is rotated by more than 360 degrees to intermittently permit a timing shot when passage of the ball is synchronized to the rotation of the flipper. For example, the flipper may intermittently open a path for a ball to a target, or may intermittently permit the ball to be deflected by the flipper to a target. In either case, a player's attention is captivated by turning the motor on and off at different times in a game sequence, and permitting the player to have a degree of control over the angular velocity of the flipper. In another embodiment, the flipper is both rotated by a motor and pivoted by a solenoid, the player adjusts a control to select the angular position of the flipper, and the player activates a switch to actuate the solenoid.
