JPS5916947Y2 - electronic organ key device - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a key device for an electronic orchard.

Originally, touching a piano key requires a relatively large operating force at the moment the key is pressed, and when the hammer is actuated through the action, the operating force suddenly decreases.

However, the key of an electronic organ exhibits a linear change following the initial pressure as shown in FIG. 1 when pressed against a spring.

Therefore, it is difficult for those who are familiar with the piano to play the electronic organ, and it is also difficult for those who are familiar with the electronic organ to play the piano.

The present invention eliminates the above-mentioned inconvenience by making the key touch of an electronic organ similar to that of a piano.The lock body 1 is formed into a U-shaped cross section to form an inner space 2.
In the type in which the inner side walls 3, 3 of are guided by a guide bushing 5 made of rubber or other elastic body to which a guide pin 4 is attached, the lower part of the inner side walls 3, 3 is bulged inwardly. It serves as a resistor 6 for the passage of the guide bush 5.

In FIG. 2, 7 is a spring that pulls the lock body 1 upward, 8 is a collar that restricts its upward movement, and 9 is a chassis.

Thus, when the lock body 1 is pushed down, the resistors 6, 6 abut the guide bush 5 from both sides to resist its downward movement, and the guide bush 5 passes between the tops of the paper antibodies 6, 6.

After passing through this point, the operating force suddenly drops, and then the operating force gradually increases as the spring 7 changes.

The above is illustrated in the fourth figure, which is similar to the touch of a key when operating a hammer through an action on a piano.

In this way, according to the present invention, the inner side wall 3 of the lock body 1
, 3 are bulged inward to serve as resistors 6, 6 for the passage of the guide bushes 5, so that the resistance at the initial stage of pressing the key provides a key touch similar to that of a piano key, as described above. This has the effect of resolving such inconveniences.

Claims (1)

[Scope of utility model registration request] The lock body 1 is formed into a U-shaped cross section to form an inner space 2, and the inner walls 3, 3 of the inner space 2 are guided to a guide bush 5 made of rubber or other elastic material attached to a guide pin 4. In the electronic organ key device, the lower part of the inner side wall 3°3 is inwardly bulged to serve as a resistor 6 in the passage of the guide bush 5.
