Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a keyboard of an electronic musical instrument or the like in which a plurality of keys are integrally molded.

(Prior Art) As shown in FIG. 5, the keyboard is, for example, a white key a of the scales CB.
Is connected to the common mounting portion c via the hinge b by integral molding, and the black keys d of, for example, the scales C ^{# to} A ^# are integrally molded on the common mounting portion f via the hinge portion e. Of the white keys a of the white key group A, the upper limit stopper g of the white keys a of the scales C, D, E, G, A, and B of the white keys a of the white key group A is a white key a. To the left, and the upper limit stopper g ′ of the white key a of the scale F to the right,
The upper limit stopper h of the black key d is projected forward from the tip of the black key d, and the keyboard is attached at the common attachment parts c and f on the keyboard frame i as shown in FIG. An electronic device in which g and g ′ are brought into contact with a stopper cushion j provided on the back surface of the keyboard frame i, and an upper limit stopper h of the black key d is brought into contact with a stopper cushion k provided at another position on the back surface of the keyboard frame i. Electronic musical instruments such as organs have been proposed.

(Problems to be Solved by the Invention) In the above-mentioned integrally molded keyboard, since there is no key guide, the key a (or d) faces toward the adjacent key a (or d) by molding as shown in FIG. If there is, there is no cure,
Also, the keys a and d tend to tilt. Further, since the upper limit stoppers g, g'and h are in opposite directions and are displaced from each other, two stopper cushions j, k are required and a white key a and a black key d are required when assembling the key on the keyboard frame i. Must be assembled separately, which makes the work difficult.

The present invention aims to solve the above-mentioned conventional problems.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a keyboard of an electronic musical instrument or the like in which a plurality of keys are integrally molded and connected to a common mounting portion through hinge portions, The white and black key guides guided by the key guide are arranged near the tip of the black key, and the upper limit stoppers of the white and black keys are arranged behind the guide wall of the adjacent key. To do.

(Operation) Since the guide parts of the white key and the black key are guided by the key guide provided on the keyboard chassis, even if the key faces the adjacent key at the time of molding, it is corrected by the key guide, and the white key and the black key are also corrected. The key does not tilt when pressing. Since the upper limit stoppers of the white key and the black key are arranged behind the guide wall of the white key and the black key which are arranged near the tip of the black key, the stopper cushions of the white key and the black key can be one. .

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

1 to 4, 1 is a white key, 2 is a black key, and 3 is a key guide.

As shown in FIG. 4, the keyboard has, for example, scales C, E,
Through G, the white key assembly ₆₁ connected by integral molding to the common mounting portion 5 white key 1 B via the hinge portion 4, for example scale D, F, the white key 1 of A hinge portion 4 Common mounting part 5
The white key assembly 6 ₂ connected by integral molding, for example scale ^{C ♯, D ♯, F ♯} , G ♯, by integrally molding the common mounting portion 8 black key 2 A ^♯ via a hinge portion 7 It is composed of linked black key assemblies 9 and is mounted on the keyboard frame 16 at common mounting portions 5 and 8 as shown in the first illustration.

As clearly shown in FIGS. 2 and 3, on the lower surface of the tip portion of the black key 2, a guide portion 11 composed of opposing side walls 10 is extended downward, and the black key tip portion of the white key 1 is provided. On the lower surface in the vicinity, a guide portion 13 composed of opposing side walls 12, 12 is extended downward. A black key upper limit stopper extending behind the side wall 12 of the guide portion 13 of the white key 1 adjacent to the one side wall 10 of the guide portion 11.
14 is provided, and on the same side wall 12 of the guide portion 13, a white key upper limit stopper 15 extending behind the side wall 10 of the guide portion 11 of the adjacent black key 2 is provided. The upper limit stoppers 15 are arranged on a straight line.

The side wall 12 of the guide portion 13 of the white key 1 and the side wall 10 of the guide portion 11 of the black key 2 mounted on the keyboard frame 16 are respectively inserted into the slits 17 of the keyboard frame 16, and the key guides mounted on the keyboard frame 16 are attached. The white key upper limit stopper 15 and the black key upper limit stopper 14 come into contact with the side surface of the keyboard 3 and the stopper cushion 18 provided on the back surface of the keyboard frame 16.

In FIG. 1, 19 is a bowl-shaped rubber member having a movable contact built therein.
A keyboard switch composed of 20 and a switch board 21 on which fixed contacts are arranged. This is a cantilever-shaped attachment to the keyboard frame 16 of the switch board 21, and the key guide 3 and the key guide 3 are provided at the other end of the switch board 21. The end portion of the stopper 22 that is integrally molded is in contact with.

As in this embodiment, the white key 1 is replaced by two white key aggregates 6 ₁ and 6
_The configuration of ₂ has an advantage that a slide mold is not required unlike the case where all the white keys 1 are integrally molded.

(Advantages of the Invention) Since the present invention is configured as described above, in a keyboard in which a plurality of keys are integrally molded, even if the keys are facing the adjacent keys, they can be corrected and tilted. In addition, there is an effect that the stopper cushion that comes into contact with the white key upper limit stopper and the black key upper limit stopper can be shared, and the man-hour and material cost can be reduced.
