Problems solved by technology

[0016] However, in the background art described above, even before the protrusion abuts against the protrusion, resistance is generated when the protrusion slides on the flat surface as the key rotates, and the load due to this resistance acts on the key in a gradually increasing manner. key
As a result, after the resistance feeling gradually increases corresponding to the key stroke, the protrusion will press against the protrusion, so there is a problem that it is difficult to recognize the increase in the resistance feeling when the protrusion touches the protrusion.
Furthermore, since the protrusion slides on the flat surface after the protrusion passes over the protrusion, there is a problem that it is also difficult to recognize a decrease in the feeling of resistance when the protrusion passes over the protrusion.
This change in the sense of resistance that is difficult to recognize is different from the click feeling of an acoustic piano, and there is a problem of feeling uncomfortable

Embodiment Construction

[0096] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. First, refer to Figure 1 to Figure 3(a) , FIG. 3(b) to describe the keyboard device 1 according to the first embodiment of the present invention. figure 1 and figure 2 It is a side view of the keyboard device 1 of the first embodiment, figure 1 Indicates the off-key state, that is, the initial state, figure 2 Indicates the state of the key, that is, the state of the key. In addition, the left-right direction of the keyboard device 1 is based on the direction viewed from the player when it is mounted on an electronic keyboard device (not shown), and the front-to-back direction is the direction of the keyboard device when it is mounted on an electronic keyboard device (not shown). The player side of 1 is "Front".

[0097] figure 1 The illustrated keyboard device 1 is configured as a keyboard operation unit for a player, and is a device for detecting the o...

Abstract

A keyboard device capable of reconstructing a unique clicking sense of an acoustic piano is provided. A first incline portion (a plane or curved surface) of a sliding surface is inclined towards a direction gradually departing from a base portion of a protrusion along a displacement direction of the protrusion in a key-pressing operation for reducing a resistance exerted on the protrusion and suppressing a gradual increase of a sense of resistance. Moreover, a bump portion located at where the protrusion reaches after sliding through the first incline portion is used to increase the resistance exerted on the protrusion for increasing the sense of resistance. When the protrusion crosses over the bump portion, the sense of resistance is reduced. Accordingly, variation in the sense of resistance before and after the bump portion is increased, and the unique clicking sense of the acoustic piano is reproduced.

Description

technical field [0001] The present invention relates to a keyboard device, and more particularly to a keyboard device capable of reproducing the click feeling peculiar to an acoustic piano. Background technique [0002] Conventionally, in electronic keyboard instruments such as electronic pianos, there has been a technique in which a hammer with a predetermined mass is placed under the key, and the hammer is rotated and displaced as the key is pressed, thereby correcting the key. By imparting a predetermined action (action) load, it approximates the key touch of an acoustic piano. Furthermore, an acoustic piano has a characteristic click feeling in which, when a key is pressed slowly, the resistance feeling increases halfway and then quickly becomes lighter. By reproducing this click feeling, the key tactility of the electronic keyboard instrument can be made more similar to the key tactility of an acoustic piano. [0003] As such a technique, for example, Patent Document ...
