[0028] [Structure of keyboard device 1]

[0029] The keyboard device 1 according to the first embodiment of the present invention is an example in which an example of the support assembly according to the present invention is applied to an electronic piano. In order to impart a tactile feeling similar to that of a grand piano when the keys are operated, this electronic piano includes a configuration similar to that of a support assembly of a grand piano. refer to figure 1 The keyboard device 1 according to the first embodiment of the present invention is outlined.

[0030] figure 1 is a side view showing the mechanical configuration of the keyboard device according to the embodiment of the present invention. Such as figure 1 It is shown that the keyboard device 1 according to the first embodiment of the present invention includes a plurality of keys 110 (in this example, 88 keys) and an action mechanism corresponding to each key 110 . The action mechanism includes the sup...

Abstract

A support assembly includes a support rotatable with respect to a frame, a repetition lever rotatable with respect to the support, and a first extension portion disposed to the repetition lever on a jack side with respect to the center of rotation of the repetition lever, the first extension portion being in contact with a stopper from below the stopper.

Description

technical field [0001] The present invention relates to support assemblies for use in keyboard devices. Background technique [0002] Acoustic pianos, such as traditional grand and upright pianos, are made up of many parts. Furthermore, since the assembly of these components is highly complicated, the assembly work takes a long time. In particular, assembly of the action mechanism provided corresponding to each key is highly complicated because the action mechanism requires many parts. [0003] For example, Japanese Patent Application Laid-Open No. 2005-292361 discloses an action mechanism in which a plurality of components interact with each other to transmit key-press and key-off motions to hammers. In particular, part of the action mechanism consists of a support assembly that works through a combination of various components. The support assembly includes not only a mechanism for realizing the strike of the string by the hammer according to key depression, but also an...
