摘要： A panel operator structure having operator units respectively disposed in position relative to operator unit insertion holes, thereby preventing key tops of the operator units from being in contact with the insertion holes. Switches are provided on an upper surface of a base plate and operation unit insertion holes are formed in an operation panel made of metal. Each operator unit includes a key top connected for vertical pivot motion to a casing via a hinge, and frame portions continuously formed together in an upper part of wall portions. The key top is disposed inside the frame portions with a gap therebetween. The frame portions fitted in the insertion hole restrict a horizontal positional motion of the operator unit relative to the operator insertion hole.
