Abstract
A pinball game playfield feature includes a circular table which is rotated by a motor and linkage. Mounted on the table is a target housing having optical emitters disposed therein. Optical detectors are located in the table. Each emitter-detector pair forms a light beam which can be interrupted by a pinball to signal the game microprocessor for scoring or other purposes. Rotation of the table permits selectable positioning of the optical target bank.
