摘要： A keyboard musical instrument equipped with a keyboard range display for making it possible to visually recognize the finger positions on the keyboard, and if necessary, the key positions to be depressed, includes right and left hand coverage display means (65 and 64) and preferably, key depression position display means (63). Each display means is driven by using display data included in performance data. The player can recognize instantaneously and intuitively the on range and can easily move his fingers to the range. Even when the right and left hands approach each other during the play, the player can clearly recognize the positions of th hands on the keyboard and the fingers which are to touch the keys.

摘要： A piano which has additionally an electronic sound source therein and with which the player can give a performance using the electronic sound source in addition to an ordinary piano performance. When the player gives both an ordinary performance and an electronic sound performance, the balance between the regular performance and the performance using the electronic sound source does not vary. When a key is pressed in an electronic sound source mode, a CPU finds the key number n &cir& _ (S110), and measures the difference DELTA T between the timings at which the light-emitting elements and light receiving elements of two key sensors are interrupted from each other (S120), and a velocity V is calculated on the basis of this time difference DELTA T (S130). Performance information is then generated in a performance information generating routine in accordance with the key-pressing information (S140), and a delay time Td corresponding to the velocity V is determined by using a delay time setting table (S150). Whether the delay time Td has passed or not is judged (S160). When the delay time Td is judged to have passed, the performance information is outputted to the electronic sound source (S170). As a result, sound is produced by the electronic sound source (5) when the delay time Td corresponding to the key-pressing strength has passed after the key is pressed.

摘要： A switch mechanism of a piano with a built-in electronic musical instrument, which eliminates the disposition of switches on the surface of a piano to improve the appearance of the piano. An upright piano (1) includes a hammering mechanism (7) which strikes strings in accordance with the operation of a keyboard (3), and thus it serves as an acoustic piano as well as an electronic piano because it has a built-in electronic sound source (9) controlled by the operation of the same keyboard (3). This upright piano (1) includes an inhibition mechanism (13) for inactivating the hammering mechanism (7) in electronic mode, a pedal mechanism (17) having a muffler pedal (16), a control portion (19) driven by a power supply (18) for controlling the electronic sound source in accordance with the operation of the keyboard (3) to produce sounds, and a power supply switch (21) turned ON/OFF by the actuation of the muffler pedal (16) to make and break the electrical connection between the power supply (18) and the control portion (19).
摘要翻译：具有内置电子乐器的钢琴的开关机构，其消除了钢琴表面上的开关的布置以改善钢琴的外观。立式钢琴（1）包括根据键盘（3）的操作撞击琴弦的锤击机构（7），因此它作为原声钢琴和电子钢琴，因为它具有内置的电子声源（9）由同一键盘（3）的操作控制。这种立式钢琴（1）包括用于以电子模式灭活锤击机构（7）的禁止机构（13），具有消音踏板（16）的踏板机构（17），由电源驱动的控制部分（18），用于根据键盘（3）的操作来控制电子声源以产生声音，并且电源开关（21）通过消音踏板（16）的致动而导通/断开，以使断开电源（18）和控制部分（19）之间的电连接。

摘要： A piano having electronic sound sources, which is played with a touch as if it were an acoustic piano. At step S100, the speed of a key (5) is detected by key sensors (33) and (35). At step (110), the key striking force is obtained by converting the key speed in accordance with a conversion table representing a touch curve stored in a ROM (43). At step S120, a sound is generated from a speaker by controlling an electronic sound source (9) and an amplifier (11) on the basis of the converted key striking force. This key striking force is data representing a sound volume. However, the conversion table in this embodiment is set beforehand in such a manner that the sound volume becomes equal to the sound volume of an acoustic piano even when an electronic piano is played with a touch of an acoustic piano. Therefore, performance can be made without the sense of incompatibility.
摘要翻译：具有电子声源的钢琴，如同原声钢琴一样被触摸。在步骤S100中，键（5）的速度由键传感器（33）和（35）检测。在步骤（110），通过根据存储在ROM（43）中的表示存储的触摸曲线的转换表来转换键速度来获得键击。在步骤S120中，通过基于转换的键击力控制电子声源（9）和放大器（11），从扬声器产生声音。这个关键的打击力是表示音量的数据。然而，本实施例中的转换表是预先设定的，即使当用原声钢琴的触摸播放电子钢琴时，音量也等于声学钢琴的音量。因此，可以在没有不兼容性的情况下进行性能化。
