  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIGS. 1, 2 and 3 are a block diagram, a front view and a partial plan view showing an electronic keyboard instrument according to the first embodiment of the present invention.

  The keyboard instrument 10 of this embodiment includes a CPU (Central Processing Unit) 1 that controls the entire keyboard instrument 10. The CPU 1 is a ROM (Read Only Memory) 2 in which a control program, PCM (Pulse Code Modulation) data, and the like are stored. The CPU 1 is a work area of the CPU 1, and information on music input from the outside of the keyboard instrument 10 is described later. A RAM (Random Access memory) 3 capable of storing information on the key of the music set on the setting panel 11 and a sound source circuit 7 capable of simultaneously generating a plurality of sounds are connected via an internal interface. The song information stored in the RAM 3 includes, for example, information such as the sound used for the song input from the outside of the keyboard instrument 10 and the number of times the sound is used.

  The sound source circuit 7 is connected to a speaker 9 via a D / A (Digital / Analog) converter (not shown) and an amplifier 8. The keyboard instrument 10 includes a keyboard unit 4 for inputting sound. The keyboard unit 4 has a plurality of keyboards 21 for instructing the timing of sound to be generated or muted (see FIG. 2). The keyboard unit 4 is connected to the CPU 1 and the like via a keyboard unit interface circuit 5 that scans on / off of each keyboard 21 to detect the operated keyboard 21.

  The CPU 1 and the like are connected via an internal interface to a setting panel 11 that can set a key to be a transposition destination. For example, the setting panel 11 is used to set the key of the music played by the keyboard instrument 10 in accordance with the operation input of the user of the keyboard instrument 10. For example, an operation button (not shown) is provided on the setting panel 11, and the CPU 1 sets a transposition destination when the user operates the operation button. The CPU 1 and the like are connected via an internal interface to an automatic transposition program storage unit 6 in which an automatic transposition program is stored.

  The automatic transposition program discriminates the key of the song input from the outside of the keyboard instrument 10, and based on the sound information stored in the RAM 3, the determined key sound is changed to the key tone set on the setting panel 11. Used to transpose keys by shifting. As the music input from the outside of the keyboard instrument 10, for example, music input by the user hitting the keyboard 21 can be considered. This is hereinafter referred to as initial setting. However, when the user is a beginner, it is difficult for the beginner to input a certain piece of music. Therefore, in this case, the user may input the sounds one by one by hitting the keyboard regardless of the tempo of the song. In this case, the user may input while viewing the score. In addition, as a score in this case, a score that can be used by the keyboard instrument 10 according to the present embodiment may be prepared in advance.

  As shown in FIGS. 2 and 3, the keyboard instrument 10 includes a keyboard portion 4 and a support portion 17 that can support the keyboard portion 4. The keyboard unit 4 is composed only of a keyboard 21 arranged in the X direction so that the pitch is a whole tone, a whole tone, a semitone, a whole tone, a whole tone, a whole tone, and a semitone. All the keyboards 21 have the same color, for example, are set to white, and no black key is provided. In addition, although the example of all the same colors was shown, for example, the keyboard 21 corresponding to “do (pitch name)” is made different in color from other keyboards, or the keyboard color is changed in every octave. It may be. In addition, it is preferable that the position of the keyboard 21 for generating the key tones of the transposition destination set on the setting panel 11 is set to the position of the center (middle) of the keyboard unit 4, for example. This position may be marked or light-emitting as can be seen at a glance.

  On the upper surface of the support portion 17, a housing portion 18 is provided on the back side in the Y direction when viewed from the keyboard 21 side. The housing portion 18 houses a performance support board 15 for supporting performance. The performance support board 15 is provided on each keyboard 21 so as to be slidable in the Y direction from the initial setting position S within the plane in which each keyboard 21 is arranged. By sliding the performance support board 15 in the Y direction, the performance support board 15 can be moved to the space on each keyboard 21 and overlapped on the keyboard 21. The performance support board 15 is, for example, a transparent sheet with a note name such as “Doremifasolaside”. Note that, for example, a transparent sheet with black keyboard marks and numbers may be used instead of the pitch names, or each keyboard 21 may be seen in a different color by sliding and overlapping each keyboard 21. A colored translucent sheet may be used. Further, the color of each keyboard 21 itself may be changed similarly.

  Next, the operation of the keyboard instrument 10 will be described with reference to the drawings. The steps after the above-described initial setting has been completed and the key information of the transposition destination has been set in advance from the setting panel 11 and stored in the RAM 3 will be described. For beginners and the like, it is preferable to set a transposition destination in “C major” which is easy to perform, for example.

  As shown in FIG. 4, in step 10, the CPU 1 determines the key of the input music by using the sound of the music stored in the RAM 3 by the automatic transposition program and the information on the number of times the sound is used. For example, select eight pieces of input sound information in descending order, calculate the pitch between each selected note, and determine that the pitch is full, full, half, full, full, full, and half To do. On the other hand, when the pitch between the selected sounds becomes full tone, semitone, full tone, full tone, semitone, full tone, and full tone, it is determined as a minor tone.

  In step 11, the lowest sound among the information of the eight sounds is determined as the main sound. As a result, it is assumed that the key of the song is determined to be “e major”, for example.

  In step 12, the tone of the music determined in steps 10 and 11 is transferred to the tone of the key set on the setting panel 11, and transposed. For example, when the key of the transposition destination set on the setting panel 11 is “C major” and the key of the song determined in Steps 10 and 11 is “E major”, it is set to shift four semitones.

  As described above, in the present embodiment, the keyboard instrument 10 includes the keyboard unit 4 including only the keyboard 21 arranged so that the pitch is a whole tone, a whole tone, a semitone, a whole tone, a whole tone, a whole tone, and a semitone. . That is, the keyboards 21 are arranged without providing black keys that may cause beginners to move away from the keyboard instrument 10. Thereby, while ensuring each keyboard 21 required for the performance of a music, a beginner can easily work on the keyboard instrument 10, and a beginner can easily perform. Since the number of keyboards 21 and the like prepared for manufacturing the keyboard instrument 10 can be reduced, the cost can be reduced.

  In the present embodiment, all the keyboards 21 have the same color. According to such a configuration, it is possible to tackle the keyboard instrument 10 like a beginner tackles a percussion instrument, and it is not necessary to prepare the keyboard 21 of a different color or shape in order to manufacture the keyboard instrument 10, so that the cost is low. Can be achieved. In the present embodiment, the electronic keyboard instrument 10 is illustrated. However, in the case of a keyboard instrument such as an acoustic piano, the number of hammers and strings that strike the strings can be reduced by pressing the keyboard or the keyboard. Therefore, the cost can be reduced.

  In the present embodiment, key information set on the setting panel 11 is stored, and automatic transposition is performed by an automatic transposition program. Thereby, it is possible to easily transpose information such as the frequency for transposing without the user setting. Accordingly, it is possible for the performer to perform in synchronism while listening to the transposed music. At this time, it is preferable to prepare a transposed musical score in advance. Thereby, it is possible to perform while watching a score prepared in advance, so that the performance becomes easier.

  In the present embodiment, the performance support board 15 is provided on each keyboard 21 so as to be slidable in the Y direction within the plane on which each keyboard 21 is arranged. For this reason, the performance support board 15 can be slid and superimposed on each keyboard 21 at the time of performance, and the performance support board 15 can be used for performance. Therefore, it is possible to perform more easily. In addition, when the performance is finished, the performance support board 15 can be slid again by using the space on each keyboard 21 effectively. That is, it is easy to slide the performance support board 15 because there is no black key.

  As shown in FIG. 5, the keyboard instrument 30 of the present embodiment includes an automatic performance device 50 capable of automatically playing music. The automatic performance device 50 is provided on the upper surface of the support portion 17. The automatic performance device 50 includes a casing 51 placed on the upper surface of the support portion 17 and a plurality of key pressing portions 52 provided so that each key 21 can be pressed from above. For example, a synthetic resin member for preventing displacement of the automatic performance device 50 may be provided on the lower end surface of the casing 51 so that the automatic performance device 50 is stably supported on the upper surface of the support portion 17. It is preferable to provide a recess on the upper surface of 17.

  In the casing 51, as shown in FIG. 6, a CPU 57 for controlling the automatic performance device 50 as a whole, a RAM 53 as a work area for the CPU 57, a ROM 54 for storing control programs, PCM data, music information, and the like, And an interface circuit 56 for moving the key pressing portion 52 up and down in accordance with an instruction from the CPU 57. Each key pressing portion 52 is made of, for example, a magnetic material, has a cylindrical shape, and a coil is wound around it. By controlling the voltage applied to the coil by the CPU 57, each key pressing portion 52 can be moved up and down to press each keyboard 21 from above. For this reason, it is possible to generate a delicate sound as if the performer actually hit the keyboard 21. At this time, the CPU 57 controls the amount and speed of movement of each key pressing portion 52, so that more delicate sound intensity can be generated. Since the automatic performance device 50 can be mounted on and removed from the support portion 17, it is excellent in versatility. Since it is not necessary to provide the automatic performance device 50 inside the keyboard instrument 30, it is not necessary to modify the keyboard instrument by a specialist or the like, and the cost can be reduced.

  FIG. 8 is a front view showing the pedal mechanism of the keyboard instrument of the third embodiment, and FIG. 9 is a side view showing the inside of the keyboard unit. FIG. 11 is a plan view showing a part of the keyboard unit shown in FIG. In the third embodiment, the same components and functions as those of the keyboard instrument 10 according to the first embodiment will be described briefly or omitted, and different points will be mainly described.

  The keyboard instrument 100 includes a pedal mechanism 70 that can transpose a sound by a semitone, and a keyboard unit 80 (see FIG. 9) that is operated by the pedal mechanism 70.

  The pedal mechanism 70 includes a damper pedal 71, and a first pedal 72 provided on the bass side (for example, the left side) of the keyboard 85 in the arrangement direction of the keyboard 85 and a damper pedal in the arrangement direction of the keyboard 85. 71 includes a second pedal 73 provided on the high-pitched side (for example, the right side).

  The first pedal 72 is connected to, for example, one end of a wire 75, and the other end of the wire 75 is connected to the left side of the keyboard unit 80. The wire 75 is accommodated in the pipe 76. By stepping on the first pedal 72, the wire 75 is pulled in the arrow B direction, and the keyboard unit 80 is moved in the left direction C by a semitone.

  The second pedal 73 is connected to, for example, one end of a wire 77, and the other end of the wire 77 is connected to the right side of the keyboard unit 80. The wire 77 is accommodated in the pipe 78. By stepping on the second pedal 73, the wire 77 is pulled in the arrow D direction, and the keyboard unit 80 is moved in the right direction E by a semitone.

  As shown in FIG. 9, the keyboard unit 80 is provided with a keyboard portion 180, a support member 81 that supports the keyboard portion 180, a string-striking mechanism 82, and a damper mechanism 90. The string-striking mechanism 82 and the damper mechanism 90 have a well-known structure, and these are provided for each keyboard 85. The string-striking mechanism 82 is an elliptical plate-shaped hammer 82a, (82b) for playing a string 91, 92, 93 (94-96, 97-99) (see FIG. 11) corresponding to one keyboard 85 to produce sound. 82c), a support bar 82e that supports these hammers 82a, etc., a shaft support member 82f that supports one end of the support bar 82e so that the hammer 82a rises when the player presses the keys, and a keyboard 85 when the keys are pressed. A bar member 82g or the like for raising the hammer 82a side of the support bar 82e in conjunction with The bar member 82g is configured to be interlocked with the movement of the keyboard 85 as will be described later.

  The damper mechanism 90 is connected to a damper 90a for contacting the strings 91, 92, and 93 to stop the vibration, a wire 90b connected to the damper 90a, and a lower end of the wire 90b, and the keyboard 85 is depressed by the performer. And a rotating member 90c that is pushed up by abutting against an end 85a of the keyboard 85. Further, the damper mechanism 90 is provided for each keyboard 85 as described above, but all of the damper mechanism 90 is mechanically connected to the damper pedal 71 via the push-up rod 74. Thereby, when the damper pedal 71 is stepped on by the performer, the push-up rod 74 is pushed up in the direction of the arrow A (see FIG. 8), and all the damper mechanisms 90 are activated so that the dampers 90a are separated from the strings 91 and the like. It becomes a state.

  Next, operations when the keyboard 85 is depressed and when the damper pedal 71 is depressed will be described.

  As shown in FIG. 10, when the keyboard 85 is pressed, one end of the bar member 82g rises and the other end of the support bar 82e rises in conjunction with the rise of the end 85a. The rising of the rod member 82g is limited by the bottom surface of the shaft support member 82f. The hammer 82a ascends integrally with the support rod 82e and strikes the string, and then the hammer 82a descends and separates from the string 91. The end 85a that is raised by pressing the key rotates the rotating member 90c to push up the damper 90a together with the wire 90b so that the damper 90a is separated from the string 91. As a result, the string 91 continues to vibrate while the keyboard 85 is depressed. When the performer releases the keyboard 85, the end 85a is lowered and the rotating member 90c is lowered. The damper 90a is lowered integrally with the wire 90b in conjunction with the lowering of the rotating member 90c, and the damper 90a contacts the string 91. On the other hand, when the damper pedal 71 is stepped on, the push-up rod 74 rises, and all the turning members 90c corresponding to all the keyboards 85 turn and rise. While the rotating member 90c and the like rise, the damper 90a rises integrally with the wire 90b and moves away from the string 91. When the performer releases the damper pedal 71, the push-up rod 74 is lowered and the rotating member 90c is lowered. In conjunction with the lowering of the rotating member 90c and the like, the damper 90a is lowered integrally with the wire 90b, and the damper 90a contacts the string 91. That is, while the damper pedal 71 is being depressed, the string 91 and the damper 90a can be kept apart from each other even when the key is not depressed, and the sound once played can be heard.

  Next, the operation when using the second pedal 73 will be described. FIG. 12 is an enlarged plan view of the keyboard instrument 100 when the second pedal 73 in the vicinity of the hammer 82a is used.

  As shown in FIG. 11, when the second pedal 73 is not used, for example, three strings 91, 92, 93 are provided immediately above the hammer 82a, and three strings 94, 95, 96 are directly above the hammer 82b. The three strings 97, 98, 99 are provided immediately above the hammer 82c. At this time, for example, when the performer depresses the keyboard 85 corresponding to the hammer 82a and steps on the second pedal 73, each hammer is on the high pitch side (right direction E) with respect to each string as shown in FIG. Move half a semitone. That is, the hammer 82a strikes the strings 94, 95, and 96. As shown in FIG. 13, for example, when the performer presses the keyboard 86 and depresses the first pedal 72, a keyboard 87 (not actually provided for producing a semitone lower than the sound of the keyboard 86) is provided. (Normally black key) can be produced. By pressing the keyboard 85 and depressing the second pedal 73, the sound of the keyboard 87 can be produced. In this way, it is possible to produce a sound that is shifted by a semitone from the sound of the keyboard provided at every sound interval.

  As described above, the keyboard instrument 100 according to the present embodiment includes the pedal mechanism 70 that moves the semitone hammer 82a toward the low tone side or the high tone side relative to the string 91 or the like. For this reason, beginners can perform using only the keyboard 85 without using the pedals 71, 72, 73. For example, a person of intermediate level or higher performs by raising or lowering the sound by a semitone using his / her feet. be able to.

  The keyboard instrument 100 according to the present embodiment has a first pedal 72 arranged on the low-pit side with respect to the damper pedal 71 in the arrangement direction of the keyboard 85, and a first pedal 72 arranged on the high-pitched side with respect to the damper pedal 71 in the arrangement direction of the keyboard 85. 2 pedals 73. For this reason, the first pedal 72 is positioned on the left and the second pedal 73 is positioned on the right with the damper pedal 71 interposed therebetween. Accordingly, since the left and right feet can be made to correspond to the lowering of the semitone of the sound, intuitive performance is possible, and performance using the first pedal 72 and the second pedal 73 can be facilitated. .

  In this embodiment, by stepping on the first pedal 72, the hammer 82a and the like can be moved to the bass side in the direction in which the strings 91 and the like are arranged via the wire 75, and the second pedal 73 is stepped on. As a result, the hammer 82a and the like can be moved to the treble side in the direction in which the strings 91 and the like are arranged via the wire 77. For this reason, for example, a mechanism similar to a known shifting pedal that moves the hammer in the direction of arrangement of the strings in order to reduce the sound can be used for the pedal mechanism 70, so that the cost can be reduced.

  FIG. 14 is an enlarged plan view showing the pedal mechanism of the keyboard instrument according to the fourth embodiment.

  In the present embodiment, the hammer 82b is provided so as to be rotatable by a semitone on the low-pitched sound side and the high-pitched sound side around the rotation shaft 101 perpendicular to the direction in which the strings 91 and the like are arranged. The tip of the hammer 82 b is connected to one end of the wire 105, and the other end of the wire 105 is connected to the first pedal 72. The tip of the hammer 82 b is connected to one end of the wire 106, and the other end of the wire 106 is connected to the second pedal 73. The other hammers are similarly configured.

  In the present embodiment, when the performer steps on the first pedal 72, the hammer 82b can be rotated around the rotation shaft 101 by a semitone toward the low tone side, and by pressing the second pedal 73. The hammer 82b can be rotated around the rotation shaft 101 by a semitone toward the high sound side. Even in this way, similarly, using the first pedal 72 and the second pedal 73, it is possible to raise or lower the key-pressed sound by a semitone.

  The present invention is not limited to the embodiments described above, and various modifications are possible.

  For example, a ROM (not shown) in which the sound of a song and key information of the song are stored in advance is provided, and an automatic transposition program having only step 12 of the automatic transposition program of the first embodiment is provided. Also good. In this case, the automatic transposition program automatically transposes the sound information of the music stored in the ROM to the sound of the music set in the setting panel 11 based on the music key information stored in the ROM. Used for. In such a configuration, since the music key information is stored in the ROM in advance, it is not necessary to discriminate the music key as in the first embodiment. Therefore, since it is possible to prevent the transposition of the music from being unable to be accurately transposed due to inaccuracy, it is possible to transpose reliably and quickly.

  In the said 1st Embodiment, the example which transposes using the automatic transposition program using the sound currently used for the music, and its usage frequency was shown. However, the transposition program is not limited to this. For example, paying attention to the fact that a main sound often comes at the beginning or end of a song, the main sound may be determined based on the first or last sound of the song. Further, as in the above embodiment, the key of the music may be determined, and the first or last sound of the music may be used to determine whether or not the key determination is appropriate.

  In the first embodiment, the example in which it is determined whether or not the music is in major key in Step 10 and the main sound is determined in Step 11 is shown. However, after determining the main sound, it may be determined whether or not the music is in major key.

  In the first embodiment, in the initial setting, an example is shown in which the user inputs information of a song by playing the song by hitting the keyboard with the keyboard unit 4 or the like. However, the input device is not limited to this. For example, as shown in FIG. 1, a microphone 12 capable of inputting music information from the outside of the keyboard instrument 10 and a CD-ROM drive (not shown) are passed through a sampler unit (not shown) for converting sound into digital data. May be connected. The same effect can be obtained by sampling the sound input from the microphone 12 or a CD (Compact Disk) -ROM drive (not shown), and similarly determining and transposing the key based on the sound information. .

  In the first embodiment, the example in which the key information of the transposition destination set on the setting panel 11 and the information on the sound of the music are stored in the same RAM 3 is shown. However, the key information set on the setting panel 11 and the music sound information may be stored in different RAMs.

  In the second embodiment, the automatic performance device 50 having the ROM 54 in which music information is stored is exemplified. However, the music information may be automatically played using the music information inputted and stored in the RAM 3 from the outside without storing the music information in the ROM 54. By doing so, the cost of the automatic performance device can be reduced.

  In the said 2nd Embodiment, the example which moves each key pressing part 52 up and down electromagnetically was shown. However, for example, the key pressing unit 52 may be moved up and down by a driving mechanism such as a cylinder driving by air pressure, water pressure, hydraulic pressure, or a linear motor. Even in this way, a delicate sound can be similarly generated.

  In the said embodiment, the example which has an automatic transposition program was shown. However, a manual transposition setting unit may be provided on the setting panel 11. Even in this way, it is possible to calculate the frequency of transposition by the user of the keyboard instrument and manually transpose, and perform the music in synchronism while the performer listens to the transposed music.

  In the above embodiment, the performance support board 15 slidably provided is illustrated. However, the present invention is not limited to this. For example, as shown in FIG. 7, in the case of an acoustic piano 40 or the like, it is provided so as to be rotatable coaxially with the rotation axis X of the lid 45 so as to be separated from and in contact with each keyboard 21. The performance support board 26 may be used. Thereby, since the performance support board can be utilized by rotating the performance support board 26 and superimposing it on the respective keyboards 21, it is easy for beginners to perform.

  In the above-described embodiment, an example in which the keyboard musical instruments 10 and 30 have the automatic transposition program and the performance support board 15 is shown, but the automatic transposition program and the performance support board 15 may not be provided.

  In the above embodiment, an example in which the present invention is applied to an electronic keyboard instrument has been shown, but it goes without saying that the present invention may be applied to an acoustic keyboard instrument.
