Title: Video disc player having adjustable end-of-play switch

Abstract: A player, such as a video disc player, includes a signal pickup carriage, which carries a travel-limit switch and which is translated during playback toward the turntable center in correlation with the speed of rotation of the turntable. The player is provided with a movable endless belt, which carries a stop element and which extends along a path parallel to the carriage path. A time-setting wheel is coupled to the belt for selectively positioning the stop element. The position of the stop element determines the point at which the carriage-mounted switch engages the stop element during carriage translation toward the turntable center. The engagement between the two elements shuts off power to the turntable motor and lifts the stylus away from a turntable-supported record.
