In FIG. 6, one end of the key 1 is supported on the chassis 2 as a fulcrum, and the other end is arranged in pitch order so that the other end can swing vertically. A hammer 3 having a sufficient mass is arranged below the key 1 so as to perform a swinging motion with the substantially central portion 4 as a fulcrum in conjunction with the depression of the key. Again hammer 3
A spring 5 is installed between the key 1 and the key 1 so as to be biased in the return direction.

I couldn't feel the let-off feeling sometimes. The present invention solves the above-mentioned conventional problems, and provides a keyboard device for an electronic musical instrument, which is not felt in a normal performance, but can feel a let-off feeling at a fingertip when a key is depressed very slowly. With the goal.

ことができる。With this structure, when the key 13 is further pushed down from the position where the one end 13b of the hammer 13 comes into contact with the roller 17 rotatably supported by the one end 16a of the elastic band 16 as shown in FIG. As shown in (b), the one end 13b of the hammer 13 rotates the roller 17 to increase the amount of displacement of the elastic belt 16 to the right in the figure and rotate upward in the figure, so that the drag force of the elastic belt 16 is increased. While the hammer 13 rotates, the key-pressing load rapidly increases and reaches its peak. When the key 11 is further pushed down, the one end 13b of the hammer 13 rotates the roller 17 as shown in FIG. 4C to rotate the roller 17 upward while decreasing the displacement amount of the elastic band 16 to the right in the drawing. Therefore, the hammer 13 is rotated while reducing the drag force of the elastic band 16, the key pressing load is gradually reduced, and finally the engagement between the one end 13b of the hammer 13 and the roller 17 is released. This key-pressing load makes the fingertips feel a touch that is very similar to the let-off feeling of an acoustic piano.
