Problems solved by technology

[0008] However, if Figure 17 The conventional structure shown is provided with the first engaging portion 13B protruding below the key mounting portion 22A, and this structure has a problem in that space efficiency is reduced, and if, for example, a hammer, Substrates, cushions, and speakers reduce the degree of freedom for mounting components
[0009] Additionally, if Figure 17 The shown conventional structure is provided with the convex portion 21 extending below the key mounting portion 22A of the key frame 20, which has a problem in that the space utilization rate and the degree of freedom of installation are reduced due to the presence of the convex portion 21.
Another problem is that since the screw N needs to be longer than ordinary screws to be inserted into the first screw hole 16 and the second screw hole 21A provided in the key supporting part 13 and the key frame 20, it affects the screw holes that can be obtained by using the standard screw N. Increased productivity achieved
[0010] like Figure 17 The shown conventional structure is provided with the first reinforcing rib 23 extending below the key mounting portion 22A, which has a problem in that the space utilization rate and the degree of freedom of installation are reduced due to the existence of the first reinforcing rib 23.

Abstract

In a keyboard device, key unit comprises: one or multiple key body; key support, for supporting body of every key; and connection part, for pivotally connecting the key support with key body along key stroke direction of key body. Key rack comprises: upper surface; and key mounting part, mounted on the upper surface, for mounting the key support of key unit. The key support of the key unit comprises a first coupling part, possessing hook structure or forced fit structure; the key mounting part of the key rack comprises a second coupling part. The key unit is mounted on the key rack, the second coupling part couples with the first coupling part. The second coupling part comprises through-hole or recess part for coupling with hook structure or forced fit structure of the first coupling part. The coupling position of the first coupling part and the second coupling part lies in upper part of key mounting part of the key rack.

Description

technical field [0001] The present invention relates to a keyboard device, and in particular to such a keyboard device comprising: a key unit provided with a plurality of key bodies, a key supporting portion for supporting each key body, and a key unit pivotally connected A connecting portion of the key supporting portion, these components are integrally provided by synthetic resin; and a key frame, on which a key mounting portion for locking the key supporting portion of the key unit is provided.
