Touch control apparatus for electronic keyboard instrument.

摘要

A touch control apparatus for an electronic keyboard instrument, comprises a sensor having: an elongated insulating sheet (22) having a set of conductive pattern films (24,25) on a surface thereof, the elongated insulating sheet (22) being folded and the set of conductive pattern films (24,25) being formed to be spaced apart from each other; and a pressure-sensitive element (23) sandwiched in a space defined by the folded elongated insulating sheet (22) to be in contact with the conductive pattern films (24,25). The pressure sensitive element (23) is deformed when a key of the instrument is depressed to deliver an electrical output through the conductive films (24,25) representing the magnitude of the key depression. The apparatus is superior in easiness of handling the sensor and of assembling the apparatus.
