发明名称 PHONOGRAPH TOY
摘要 A toy phonograph includes a record with 12 grooves, the grooves having lead-in portions spaced about the periphery of the record. When a cord is pulled to wind a spring motor it positions a stop and the record turns in reverse until it hits the stop, the stop therefore determing which groove will be engaged by the needle when the record is played. The stop can be shifted to choose a different record groove by turning an index wheel.
