Abstract

PURPOSE:To allow performance with the same fingering by horizontally arraying respective keys in order of chromatic scales, arraying respective operating surfaces at equal intervals, and positioning the operating surfaces of sub-keys lower than the corresponding operating surfaces of adjacent main keys. CONSTITUTION:The respective main keys 1 are allotted to natural tones C, D, E, F, G, A, and B and are formed white in color. The respective sub-keys are allotted to derived tones C#, D#, F#, G#, and A# and are formed black in color. These keys are arrayed in order of C, C#, D, D#, E, F, F#, G, G#, A, A#, A, A#, B, and C in one horizontal array from the left to the right in order of the scales. The operating surfaces 3 of the respective main keys 1 are formed approximately flush with each other and the operating surfaces 4 of the respective sub-keys 2 are formed lower than the corresponding operating surfaces 3 of the adjacent main keys 1. The respective operating surfaces of the respective keys are spaced approximately equidistantly from each other in such a manner and since the respective keys are arrayed horizontally in one row in order of the chromatic scales, the performance with the same fingering at the time of transposition is possible.

Description

[Detailed description of the invention]

[0001]

[Industrial application field]

The present invention relates to a keyboard used for pianos, electronic musical instruments, etc., which is played with the fingers of the hand. [0002]

[Conventional technology]

The natural scale is made up of the main tones C, D, E, F, G, A, and B, and the intervals between adjacent tones are different. In other words, there are semitones between the notes E and F and between notes B and C, and the rest are whole steps. for that,
It was difficult to create a musical instrument keyboard that would allow hands to easily play the key notes and also transpose keys easily. [0003] In the standard keyboard of US Pat. No. 4,782,734, the intervals between the white keys (stem keys) and the pitches at the front do not match, making transposition difficult. In addition, in the rear part, the white key (main key)
is lower than the black keys (derivative notes), making it difficult to play the white keys (main notes). [0004] The keyboard of US Pat. No. 4,444,083 has E, F, and B keys compared to this standard keyboard. By making the width of the C white key 3/4 of the width of the G and A white keys, the distance between the white keys is brought closer to the pitch interval. However, each time you transpose, which key to press, the white key at the front or the black key at the rear, changes, making the change in fingering irregular, making transposition difficult. [0005] In the embodiment of the pedal keyboard of US Pat. No. 4,658,696, which is set in a scale arrangement, the key of the main note is higher than the keys sandwiched between them to form the valley, so that the key of the main note is It's easier to play. However, since the keys of the main tones are arranged at equal intervals with valleys in between, the intervals of the main tones do not match the intervals of the pitches. Therefore, it is not possible to transpose using the same foot, making transposition difficult. [0006] In the keyboard of US Pat. No. 3,392,620, the front keys and the high keys at the rear are arranged at intervals of whole steps (twice a semitone), so transposition for each whole step can be performed using the same fingering. is easy. However, because the main note is located at the front or at the back, it is difficult to detect and play the main note. (The same applies to US Pat. No. 3,468,209.) [0007] The pedal chromatic keyboard of US Pat. No. 3,433,881 has keys spaced at semitone intervals, making transposition easy. It is difficult to sense the position of
The main note is difficult to play. [0008]

[Problem to be solved by the invention]

The present invention aims to solve the aforementioned problems. In other words, the key of the key is easy to detect, the key is easy to play, and when transposing, you can play with the same fingering without having to move your fingers back and forth, making it easy to transpose. The purpose is to provide a flexible keyboard. [0009]

[Means to solve the problem]

The present invention for solving the above-mentioned problems has a plurality of keys arranged horizontally in one row, each key arranged horizontally in chromatic order,
Each key has an operation surface on its upper part, and each operation surface is arranged in a row horizontally at approximately equal intervals, and each key has a plurality of main keys assigned to the main tone and a plurality of keys assigned to the derivative notes. The operating surface of each subkey is a flexible keyboard for hands that is lower than the corresponding operating surface of the adjacent main key. are spaced 9 to 15 mm apart, the distance between the upper sides of the opposing sides of each adjacent key is 2 to 6 mm, and the lower parts of the opposing sides of each adjacent key protrude to face each other, allowing the upper and lower sides to overlap. Each main key and sub key has an auxiliary operation surface at the rear of the operation surface, and the auxiliary operation surface of each sub key is higher than the corresponding auxiliary operation surface of the adjacent main key. It is a flexible keyboard for [0010]

[Effect]

According to the above configuration, each key is lined up horizontally in chromatic order, and each operation surface above each key is lined up in a horizontal line at approximately equal intervals, so the distance between each key and its key are The pitch intervals of the notes assigned to the key match, and when transposing, you can play with the same fingering without having to move your fingers back and forth.
Easy to transpose. Furthermore, the operation surface of each sub-key is lower than the corresponding operation surface of the adjacent main key, so
The main key assigned to the main note is easy to detect, and the main note is easy to play. In addition to the above, the distance between the operation surfaces of each key is 15 mm or less, making it suitable for pressing two keys at an octave interval with one hand at the same time.
Since it is 9mm or more, each finger is suitable for pressing one key. Furthermore, since the distance between the upper portions of the opposing sides of adjacent keys is 2 mm or more, it is possible to easily press one key without pressing the adjacent keys with one's fingers. Furthermore, since the distance between the upper parts is 6 mm or less, the operating surface of each key has a sufficient width, making it easier for fingers to sense each key. In addition, 2 to 6
Even if there is a spacing of 1 mm, the lower parts of the opposing sides of each adjacent key protrude to form upper and lower shielding parts, which prevents dirt from entering the lower part of the key. Failures such as mechanical malfunction or electrical detection failure can be prevented, and the strength of the key can be increased. Furthermore, since the width of the entire key can be made sufficiently wide, it becomes easier to visually check the key. In addition, each main key and sub key has an auxiliary operation surface at the rear of the operation surface, and the auxiliary operation surface of each sub key is higher than the corresponding auxiliary operation surface of the adjacent main key. It is now possible to perform by holding down the high auxiliary operation surface at the rear, and for main keys, by pressing the operation surface at the front of the main key, and you can apply fingerings that are almost the same as those learned on conventional standard keyboards. .

【Example】

Embodiments of the present invention will be described below based on the drawings. FIG. 1 shows a part of a first embodiment of the present invention, in which 13 or more (or 24 or more) bar-shaped keys 1 and 2 extending back and forth are arranged in a row parallel to each other. These keys 1 and 2 have an elongated operation surface 3.4 extending back and forth on the top thereof.
have. The widths of these operation surfaces 3.4 are approximately equal, and they are arranged at approximately equal intervals. That is, if an imaginary line extending forward and backward through the center of the width of these operation surfaces 3 and 4 is defined as a center line, the center lines are approximately equally spaced from each other, and the spacing is 9 to 15 (for example, 13. 5) It is mm. Since the distance between the center lines is 15 mm or less, it is suitable for pressing two keys at one octave interval at the same time with one hand. Furthermore, since the distance between the center lines is 9 mm or more, the tip of each finger is suitable for pressing only one key. Each key 1, 2 has a horizontal support line behind its respective operation surface, and each key 1, 2 can move up and down around this support line. The stroke of this key is 20-90% (for example, 6.5 mm) of the average centerline spacing at the front end of the key. , if the spacing between the center lines is narrow, the support lines of the keys 1 and 2 may be in front of the operation surface, or the support lines of the keys 1 and 2 may be in front of the operating surface, or the entire key may move up and down without the support line. It may be floated with an elastic body. Further, the pressing force of the key may be detected electrically, or the key operation surface may be used as a contact sensor so that the key itself does not move. Each key consists of a plurality of main keys 1 and a plurality of subkeys 2. Each main key 1 is C, D, E, F, G, A
, are assigned to the main tones of B, and are colored white, and each subkey 2 is assigned to the derived tones of C#, D#, F#, G#, and A#, and are colored black. These keys are C, C#D, D#, E, in a horizontal row from left to right in scale order.
They are arranged in the order of F, F#, G, G#, A, A#, B, and C. In this way, the operation surfaces of each key are approximately equally spaced, and each key is lined up in a horizontal line in chromatic order, so the distance between each key and the pitch of the note assigned to that key are The keys match, and when transposing, it is possible to perform with the same fingering without having to move the fingers back and forth, making it easy to transpose. Further, the operation surface 3 of each main key 1 is approximately concave in height, and the operation surface 4 of each sub-key 2 is lower than the corresponding operation surface 3 of the adjacent main key 1. In other words, each part of the operation surface 4 of each sub key is different from the operation surface 3 of the adjacent main key.
10 to 150%, preferably 15 to 60% (for example, 4.
5mm) lower. Therefore, the main key 1 assigned to the main note can be easily sensed, making it easier to play the main note. If this height difference is too small, the main key operation surface 3
It becomes difficult to distinguish between the and the subkey operation surface 4, and if the size is too large, the subkey operation surface 4 becomes difficult to press. The length of the operation surfaces 3 and 4 above each key is 30 to 1
20 (for example, 10100). Also each key 1
．． The support line of 2 is 60m behind the operation surface 3.4 of each key.
It is located at m. It is also substantially within the scope of the present invention to provide an additional operating section in front or behind the operating surface 3.4 of each key. [0012] FIGS. 2 to 4 show a portion of a second embodiment of the present invention,
FIG. 3 is a sectional view taken along the line XX in FIG. 2, showing a cross section of each of the keys 1 and 2. FIG. 4 is a sectional view taken along the line Y-Y in FIG. 20, and is a diagram showing the height relationship of each key 1.2. In this embodiment, the mutually opposing side upper portions 5.6 of each adjacent key 1.2 are
The distance g is 2 to 6 (for example, 4.5) mm. Therefore, the distance W between the upper parts 5.7 of the opposing sides of the keys 1 (or 2) on both sides is wider than the width p of each key 2 (or 1), and when a finger presses only one key 2 (or 1), My finger is on key 2
(or 1), you will no longer press the adjacent key 1 (or 2) even if it is slightly off the center line. However, this g
If the distance is smaller than 2mm, the effect will be small;
If the width exceeds , the width of the operation surface of each key 2 (or 1) becomes smaller, making it difficult for fingers to sense each key 2 (or 1). Further, the lower portions 8, 9 of the mutually opposing side portions of the adjacent keys 1, 2 protrude oppositely to form upper and lower shielding portions. Therefore, it is possible to prevent dirt from entering the bottom of keys 1 and 2.
Failures such as mechanical malfunction or electrical detection failure of the key can be prevented, and the strength of the key can be increased. Furthermore, since the width of the entire key can be made sufficiently wide, it becomes easier to visually check the keys 1 and 2. The front operation surface 11 of each sub key 2 is lower than the front operation surface 10 of the adjacent main key 1, as in the first embodiment. On the rear extension of the operation surface 11 of each subkey 2,
There is an auxiliary operation surface 13, and an auxiliary operation surface 12 is provided on the rear extension of the operation surface 10 of each main key 1. The auxiliary operation surface 13 of each sub-key 2 is higher than the corresponding auxiliary operation surface 12 of the adjacent main key 1, and the auxiliary operation surface 13 of each sub-key
is approximately concave-height. That is, each part of the auxiliary operation surface 13 of each sub key is different from the auxiliary operation surface 1 of the adjacent main key.
10 to 120%, preferably 20 to 60% (for example, 4
mm) is high. Auxiliary operation surface for these subkeys and main keys 12.13
is used for compatibility with conventional standard keyboards. That is, in the case of a derivative note, it is possible to perform by pressing the high auxiliary operation surface 13 at the rear of the sub key, and in the case of the main note, by pressing the operation surface 10 at the front or the auxiliary operation surface 12 at the rear of the main key. , fingerings that are almost the same as those learned on a conventional standard keyboard can be applied. In addition, the length of the operation surface 10.11 on the front of each key is 30.
~120 (for example, 60) mm. In addition, the length of the auxiliary operation surface 12.13 at the rear of each key is 20 to 120 mm.
(for example, 60) mm. Note that even if an additional operating section is provided in front of the operating surface 10° 11 in front of each key, or an additional operating section is provided behind the auxiliary operating surface 12. Included in invention. In addition, the support line of each key 1.2 is the auxiliary operation surface 12.13 of each key.
It is located 60mm further back. Other configurations and effects are similar to those of the first embodiment. [0013] By the way, this embodiment may have the following configuration instead of that shown in FIG. That is, in the third embodiment, the height of the auxiliary operation surface 13 at the rear of the sub key 2 shown in FIG. Further, in the fourth embodiment, the height of the auxiliary operation surface 12 at the rear of the main key 1 shown in FIG. Operation surface 1
1, and the height of the auxiliary operation surface 13 at the rear of the sub key 2 is made higher than the height of the auxiliary operation surface 12 at the rear of the main key 1. [0014] In the first embodiment and the second embodiment, the following is also included in the present invention. Although it is desirable that the center lines of each operation surface be at equal intervals, in terms of performance, there is no problem even if there is a deviation of substantially equal intervals, that is, within about 10% of the average center line interval, and this is included in the present invention. . In addition, the operation surfaces 3, 4, 10, 11, 12.
Included in the present invention. Also, depending on the circumstances of the performance, the arrangement of the notes assigned to each key can be arranged so that the pitch increases from right to left, or even if the arrangement is electrically reversed on electronic musical instruments. Included in invention. [0015] Also, this universal keyboard (UNIVER3AL KEYBO)
Unlike conventional standard keyboards, ARD) does not require the keys to be colored in colors with strong contrast, such as black and white, to appeal to the visual sense and to learn the forward and backward movements of the fingers and the irregular sense of distance. The color of the key 1 is not limited to white, but may be freely changed to a color such as gray, and the color of the 20 subkeys is not limited to black, but may be freely changed to a color such as green. The key to be pressed is recognized primarily by the sense of distance proportional to the pitch and the sense of height of the operating surface, and the color is auxiliary. In addition, in order to take advantage of the ability to freely transpose, each key has C, C#, D, D#, E, F, F#,
G. Corresponding to the note names of G#, A, A#, B, and C, do, na, shi, ko, mi, fa, ki, sote, u, yu, shi, do (do,
na, re, co, mi, fa, ki, so. Each key may be designated by appropriately assigning a name that can be called with a single sound such as te, la, yu, si, do, etc., and has a distinctive character. [0016]
