As shown in FIGS. 1 to 5, the above-mentioned problem is solved by a shaft 6 that is movable in the axial and rotational directions, which is supported within both rear side surfaces of the casing 1b of the keyboard 1 in a direction perpendicular to the side surfaces. The shaft holds one end of the leg member 4 and is equipped with a coil spring 3 which also serves as compression and torsion. The bottom plate of the keyboard is fitted with an elongated hole 5 through which the leg member can rotate downward, and a stopper with a width W 1 smaller than the thickness W of the leg member is provided at one short corner of the elongated hole. 5a protrudes, and a stopper 5b having a width W2 larger than W1 is provided on the opposite side of the elongated hole at a position opposite to the stopper 5a.
A stopper 5c having a width W3 larger than W is formed in a concave shape in a position parallel to and retracted from this 5b, and the tip of the leg member 4 is stopped by the stopper 5a in its resting state, and the end of the leg member 4 is stopped in the D direction of the axis by pressing. During the first movement length, the shaft moves away from the stopper 5a, rotates downward through the elongated hole 5 as the shaft rotates in the A direction, is stopped at the stopper 5b, and then moves away from the stopper 5a by pressing. In terms of length, this problem is solved by the keyboard tilt angle adjustment mechanism, which is characterized in that it is released from the locking by the stopper 5b, rotates in the A direction, and is locked at the position of the stopper 5c.
