うにしたものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a keyboard device in which a conventional keyboard device is equipped with an aftertouch function. This is designed to produce an effect on the performance depending on the pressure applied when the keys are pressed.

たり等の効果を通常の演奏で出すことができなかった。FIG. 1 is a diagram showing an embodiment of the present invention. Conventionally, a printed circuit board 6 to which a rubber contact switch 7 is connected is fixed to a keyboard chassis 5 via a spacer 9 with a mounting hiss 10.
When the key 1 is pressed, the 7-cut unit 18 presses the rubber contact switch 77 and the switch circuit is closed. With this device alone, it was not possible to produce effects such as applying vibrato to only the pressed keys, changing the volume, or applying Benku during normal performances.

な効果を生み出し実用価値の大なるものである。The present invention is provided to solve these problems. 4 is a p-pace fixed on the keyboard chassis 5, and the upper surface of the p-base 4 has a plurality of fixed contacts 4a as shown in FIG. A pressure-sensitive conductor 3 is disposed so as to be in contact with the fixed contact 4a, and a stopper felt 2 is fixed on the pressure-sensitive conductor 3. key 1 while playing
By pressing , the actuator 1b hits the stopper felt 2. The electrical resistance that the pressure-sensitive conductor 3 exerts on the fixed contact 4a changes depending on the difference in pressure at that time. As shown in FIG. 3, if the key pressing force is strong, the electric resistance value is low and current flows easily through the fixed contact 4a. This phenomenon is used to create effects necessary for musical expression, such as vibrato, volume changes, benders, etc., and has great practical value.
