When the control unit 6 receives the input signal from the input unit 4, the control unit 6 executes a setting process of transmitting the control signal of the volume adjustment, the tone color selection, the sound mode or the display mode corresponding to the input signal to the keyboard unit 3 or the sound unit 5. .. The control unit 6 may include a CPU (Central Processing Unit), but is not limited thereto.

鍵盤部３の構成について、図を参照して具体的に説明する。 The configuration of the keyboard unit 3 will be specifically described with reference to the drawings.

鍵盤台３１は、複数の鍵３２と光源部３３とを支持する台である。鍵盤台３１は、筐体２と一体に形成されていても良い。 The keyboard stand 31 is a stand that supports a plurality of keys 32 and a light source unit 33. The keyboard base 31 may be integrally formed with the housing 2.

鍵３２は、楽音と対応付けられた入力装置である。図２に示すように、鍵３２は、白鍵３２ａと黒鍵３２ｂとを含む。白鍵３２ａと黒鍵３２ｂとは鍵盤台３１に取り付けられる位置、高さ、大きさ、数、色が異なるものの個々の構成は同様であるため、以下では一つの白鍵３２ａを例として説明する。 The key 32 is an input device associated with a musical tone. As shown in FIG. 2, the key 32 includes a white key 32a and a black key 32b. Although the white key 32a and the black key 32b are different in position, height, size, number, and color attached to the keyboard base 31, their individual configurations are the same. Therefore, one white key 32a will be described below as an example. ..

図３は、鍵盤部３の断面図である。図３に示すように、白鍵３２ａは鍵盤台３１に支持される。白鍵３２ａは、白鍵本体部３２１と、表示部３２２と、第１発光部材３２３ａと、第２発光部材３２３ｂと、を含む。 FIG. 3 is a cross-sectional view of the keyboard unit 3. As shown in FIG. 3, the white key 32a is supported by the keyboard base 31. The white key 32a includes a white key main body unit 321, a display unit 322, a first light emitting member 323a, and a second light emitting member 323b.

白鍵本体部３２１は、一端を鍵盤台３１に支持され、他端をユーザに押鍵されて上下に移動可能に構成される。白鍵本体部３２１は、光を透過する樹脂で構成されるが、これに限られるものではない。 One end of the white key body 321 is supported by the keyboard base 31, and the other end is pressed by the user so that it can move up and down. The white key main body 321 is made of a resin that transmits light, but is not limited thereto.

表示部３２２は、白鍵本体部３２１の表面の、文字又は記号を表示する部分である。白鍵本体部３２１の表示部３２２のある面と反対側の面である裏面に、第１発光部材３２３ａと第２発光部材３２３ｂとが塗布される。 The display unit 322 is a portion on the surface of the white key main body unit 321 that displays characters or symbols. The first light emitting member 323a and the second light emitting member 323b are applied to the back surface of the white key main body 321 which is the surface opposite to the surface of the display unit 322.

第１発光部材３２３ａは、白鍵本体部３２１の裏面に塗布される、電磁波を吸収して発光する塗料である。第１発光部材３２３ａは紫外線を吸収して第１光である青色光を放出する。第１発光部材３２３ａは蛍光塗料、蓄光塗料を含むが、これに限られるものではない。図４（ａ）及び（ｂ）は、白鍵３２ａの上面図である。図４（ａ）に示すように、ある一つの白鍵３２ａの第１発光部材３２３ａは、第１記号であるカタカナの「ド」の文字のパターンを形成するように塗布されている。 The first light emitting member 323a is a paint applied to the back surface of the white key main body 321 that absorbs electromagnetic waves and emits light. The first light emitting member 323a absorbs ultraviolet rays and emits blue light, which is the first light. The first light emitting member 323a includes, but is not limited to, a fluorescent paint and a phosphorescent paint. 4 (a) and 4 (b) are top views of the white key 32a. As shown in FIG. 4A, the first light emitting member 323a of one white key 32a is applied so as to form a pattern of the character "do" of katakana, which is the first symbol.

第２発光部材３２３ｂは、白鍵本体部３２１の裏面に塗布される、第１発光部材３２３ａが吸収する電磁波とは別の波長の電磁波を吸収して発光する塗料である。第２発光部材３２３ｂは、第１発光部材３２３ａの上に重ねて塗布されている。第２発光部材３２３ｂは、橙色光を吸収して第２光である赤色光を放出する。図４（ｂ）に示すように、ある一つの白鍵３２ａの第１発光部材３２３ａは、第２記号であるアルファベットの「Ｃ」の文字のパターンを形成するように塗布されている。なお、図４（ａ）と図４（ｂ）とに分けて図示したが、上述のように、第１発光部材３２３ａと第２発光部材３２３ｂとは重ねて塗布されている。 The second light emitting member 323b is a paint applied to the back surface of the white key main body 321 that absorbs and emits light having an electromagnetic wave having a wavelength different from that absorbed by the first light emitting member 323a. The second light emitting member 323b is applied on top of the first light emitting member 323a. The second light emitting member 323b absorbs orange light and emits red light, which is the second light. As shown in FIG. 4B, the first light emitting member 323a of one white key 32a is applied so as to form the pattern of the letter "C" of the alphabet, which is the second symbol. Although the drawings are shown separately in FIGS. 4 (a) and 4 (b), as described above, the first light emitting member 323a and the second light emitting member 323b are coated on top of each other.

図３に戻り、光源部３３は、第１発光部材３２３ａ及び第２発光部材３２３ｂを発光させる電磁波を放射する光源である。図３に示すように、光源部３３は、鍵盤台３１に配置される。光源部３３は、第１光源３３ａと、第２光源３３ｂと、を備える。 Returning to FIG. 3, the light source unit 33 is a light source that emits electromagnetic waves that cause the first light emitting member 323a and the second light emitting member 323b to emit light. As shown in FIG. 3, the light source unit 33 is arranged on the keyboard base 31. The light source unit 33 includes a first light source 33a and a second light source 33b.

第１光源３３ａは、第１発光部材３２３ａに吸収される紫外線を放射する光源である。第１光源３３ａはＬＥＤ（Light Emitting Diode）、ブラックライトを含むが、これに限られるものではない。 The first light source 33a is a light source that emits ultraviolet rays absorbed by the first light emitting member 323a. The first light source 33a includes, but is not limited to, an LED (Light Emitting Diode) and a black light.

第２光源３３ｂは、第２発光部材３２３ｂに吸収される橙色光を放射する光源である。第２光源３３ｂはＬＥＤを含むが、これに限られるものではない。 The second light source 33b is a light source that emits orange light absorbed by the second light emitting member 323b. The second light source 33b includes, but is not limited to, an LED.

図５は、電子楽器１の上面図である。図５に示すように、第１光源３３ａと第２光源３３ｂとは、複数の白鍵３２ａ及び黒鍵３２ｂにそれぞれ配置される。 FIG. 5 is a top view of the electronic musical instrument 1. As shown in FIG. 5, the first light source 33a and the second light source 33b are arranged on the plurality of white keys 32a and the black keys 32b, respectively.

図３に戻り、第１発光部材３２３ａは、第１光源３３ａから放射される紫外線を吸収して第１変換効率で発光する。第２発光部材３２３ｂは、第２光源３３ｂから放射される橙色光を吸収して第２変換効率で発光する。第２変換効率は、第１変換効率より高い。 Returning to FIG. 3, the first light emitting member 323a absorbs the ultraviolet rays radiated from the first light source 33a and emits light with the first conversion efficiency. The second light emitting member 323b absorbs the orange light emitted from the second light source 33b and emits light with the second conversion efficiency. The second conversion efficiency is higher than the first conversion efficiency.

第２発光部材３２３ｂの発光による赤色光は、一部が第１発光部材３２３ａに吸収されるため、第１発光部材３２３ａの発光による青色光よりも表示部３２２の表面に到達しにくい。しかし、第２変換効率が第１変換効率より高いため、第２発光部材３２３ｂはユーザが第２記号を認識できる程度に十分に発光し、赤色光を表示部３２２に到達させることができる。 Since a part of the red light emitted by the second light emitting member 323b is absorbed by the first light emitting member 323a, it is harder to reach the surface of the display unit 322 than the blue light emitted by the first light emitting member 323a. However, since the second conversion efficiency is higher than the first conversion efficiency, the second light emitting member 323b emits sufficient light so that the user can recognize the second symbol, and the red light can reach the display unit 322.

制御部６が電子楽器１の表示部３２２に記号を表示させる表示処理について説明する。 A display process in which the control unit 6 causes the display unit 322 of the electronic musical instrument 1 to display a symbol will be described.

入力部４には、第１記号表示モードと第２記号表示モードとを選択するスイッチが含まれる。ユーザが第１記号表示モードを選択すると、入力部４は、第１記号表示モードが選択されたことを示す信号を制御部６に送信する。 The input unit 4 includes a switch for selecting a first symbol display mode and a second symbol display mode. When the user selects the first symbol display mode, the input unit 4 transmits a signal indicating that the first symbol display mode has been selected to the control unit 6.

制御部６は、第１記号表示モードが選択されたことを示す信号を受信すると、第１光源３３ａを発光させる第１発光信号を鍵盤部３に送信する。 When the control unit 6 receives the signal indicating that the first symbol display mode has been selected, the control unit 6 transmits a first light emission signal for causing the first light source 33a to emit light to the keyboard unit 3.

鍵盤部３は、第１発光信号を受信すると、第１光源３３ａを発光させる。第１光源３３ａが発光すると、第１発光部材３２３ａが第１光源３３ａから放射された紫外線を受けて青色光を発する。 Upon receiving the first light emitting signal, the keyboard unit 3 causes the first light source 33a to emit light. When the first light source 33a emits light, the first light emitting member 323a receives the ultraviolet rays radiated from the first light source 33a and emits blue light.

第１発光部材３２３ａが発した青色光が白鍵本体部３２１を透過し、表示部３２２に第１記号である青色の「ド」が表示される。 The blue light emitted by the first light emitting member 323a passes through the white key main body 321 and the blue "do" which is the first symbol is displayed on the display 322.

ユーザが第２記号表示モードを選択すると、入力部４は、第２記号表示モードが選択されたことを示す信号を制御部６に送信する。 When the user selects the second symbol display mode, the input unit 4 transmits a signal indicating that the second symbol display mode has been selected to the control unit 6.

制御部６は、第２記号表示モードが選択されたことを示す信号を受信すると、第２光源３３ｂを発光させる第２発光信号を鍵盤部３に送信する。 When the control unit 6 receives the signal indicating that the second symbol display mode has been selected, the control unit 6 transmits a second light emission signal for causing the second light source 33b to emit light to the keyboard unit 3.

鍵盤部３は、第２発光信号を受信すると、第２光源３３ｂを発光させる。第２光源３３ｂが発光すると、第２発光部材３２３ｂが第２光源３３ｂから放射された橙色光を受けて赤色光を発する。 Upon receiving the second light emitting signal, the keyboard unit 3 causes the second light source 33b to emit light. When the second light source 33b emits light, the second light emitting member 323b receives the orange light emitted from the second light source 33b and emits red light.

第２発光部材３２３ｂが発した赤色光が白鍵本体部３２１を透過し、表示部３２２に第２記号である赤色の「Ｃ」が表示される。このとき、第２光源３３ｂが発した橙色光が白鍵本体部３２１を透過し、白鍵本体部３２１の全体が橙色に光る。 The red light emitted by the second light emitting member 323b passes through the white key main body 321 and the red "C" which is the second symbol is displayed on the display 322. At this time, the orange light emitted by the second light source 33b passes through the white key main body 321 and the entire white key main body 321 glows orange.

第１記号表示モード及び第２記号表示モードのいずれも選択されていない場合は、制御部６は第１発光信号も第２発光信号も送信せず、第１光源３３ａ及び第２光源３３ｂはいずれも発光しないため、第１記号も第２記号も表示されない。 When neither the first symbol display mode nor the second symbol display mode is selected, the control unit 6 does not transmit the first light emission signal or the second light emission signal, and the first light source 33a and the second light source 33b are either. Does not emit light, so neither the first symbol nor the second symbol is displayed.

以上のような構成を備えることで、実施の形態１に係る電子楽器１は、鍵盤における一つの鍵に、設定されたモードによって異なる記号を表示させることができる。 By providing the above configuration, the electronic musical instrument 1 according to the first embodiment can display different symbols on one key on the keyboard depending on the set mode.

実施の形態１の第１発光部材３２３ａのように人に見えない電磁波を吸収して発光する塗料を用いることで、記号のみが発光する、ユーザが視認しやすい記号の表示を実現できる。 By using a paint that absorbs electromagnetic waves invisible to humans and emits light, such as the first light emitting member 323a of the first embodiment, it is possible to realize the display of symbols that are easy for the user to see, in which only the symbols emit light.
