Abstract

PURPOSE:To enable to perform a decision of a strike and a type of pitching ball, such as curve and the like, by automatically taking a reading of a baseball three-dimentionally thrown in a strike zone. CONSTITUTION:An optical system (10)Ihaving a visual field wider than a side width of a strike zone and a polarized recticule 5, an optical system (14) III, having a visual field equal to the side width of the strike zone and a visual field limiting frame 6 with high, middle, low decision sensors, and an optical system (14) IV, having a polarized fenceform recticule tilting against the recticule 5, are located on a reflection light axis of a picture decision mirror 3 mounted on a light axis set at the side of the strike zone. Additionally, an optical system (II) II, having a polarized recticule 5' on a light axis transmitting from the mirror 3, is situated. A signal, being obtained through the formation of an image on the optical systemsI-IV, is suppied to an electric system for the comparison operation, and this detects not only a ball speed and strike decision but also a type of pitching ball.
