Abstract
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.
Claims7
A panel operator structure for electronic equipment, comprising:
- a plurality of operator units;
- a base plate;
- an operation panel formed with fitting holes to each of which a corresponding one of the plurality of operator units is fitted, said operation panel being disposed in parallel to said base plate;
- and
- switches each having a driven portion, said switches being disposed on a side of said base plate close to said operation panel so as to correspond to the plurality of operator units, respectively,
- wherein each of the plurality of operator units includes a casing having a frame portion with an outer side surface, a key top adapted to be pivoted relative to the casing in a direction not parallel to said base plate when subjected to a depression/release operation, and an actuator adapted to be moved in unison with the key top to depress and drive the driven portion of a corresponding one of the switches,
- wherein the outer side surface of the frame portion of one of the plurality of operator units and a portion of the operation panel defining the fitting holes to which the one of the plurality of operator units is fitted are engaged with each other and constitute a horizontal position restricting unit that is adapted to restrict a position of the operator unit in a direction parallel to said base plate, and
- wherein the frame portion of the one of the plurality of operator units is integrally formed with the casing of the one of the plurality of operator units.
