Description

  The present invention relates to an apparatus for displaying the position of a keyboard to be played with a multicolor light source.

  Some electronic pianos have an LED embedded in the keyboard, flashing in time with the song, and displaying the position of the keyboard to be played.

JP 7-334073 A Japanese Patent Laid-Open No. 10-260677

  Normally, when practicing a keyboard instrument, the user reads the textbook facing up and repeats the action of reproducing the finger combination on the keyboard facing down. For this reason, the movement of the line of sight becomes frequent and patience is required. For this reason, it takes a lot of time to practice and often gives up learning.

  On the other hand, if the finger position guidance can be displayed on the keyboard, the movement of the line of sight can be omitted, so that iterative practice can be performed effectively. In order to realize this, some electronic pianos having a function of guiding a finger position by blinking an LED embedded in a keyboard are commercially available. However, this function is limited to practice using the electronic piano, and this function cannot be used for general pianos and keyboard instruments.

  Further, even in an electronic piano equipped with the above functions, the LEDs installed on one keyboard are monochromatic, and the finger to be pressed, the characteristics of the chords that the sound has, and the like cannot be displayed.

  Patent Document 1 discloses an invention about an apparatus that displays four fingering displays by flashing each of four LEDs having different shapes on one keyboard, but the number of LEDs included in one keyboard is large. Therefore, reading is complicated, and the finger display can only distinguish two types of thumb / small finger and forefinger / middle finger / ring finger, and the position of each finger cannot be displayed.

  The fingering guide display device disclosed in Patent Document 2 displays a key pressing position with one round LED, and displays a left hand / right hand distinction with two thin LEDs. At the same time, it has been proposed to change the amount of light emitted from the light emitter. However, the information from a plurality of issuers is also complicated, and the position guidance for each finger is not displayed here either.

  In view of the above-described problems, the present invention provides a detachable finger position guidance display device that can display a finger to be pressed, a characteristic of a chord, and the like and can be used for any keyboard instrument. Is an issue.

  In order to solve the above problems, a finger position guidance display device according to claim 1 is provided with at least one finger position guidance display board unit having a light source corresponding to each keyboard of a keyboard instrument, a control electronic circuit, and a personal computer. The finger position guidance display board unit is detachably installed on the keyboard of the keyboard instrument or in the vicinity of the keyboard.

  The finger position guidance display device according to claim 2 is the finger position guidance display device according to claim 1, wherein the light source of the finger position guidance display board unit is capable of simultaneously lighting a plurality of the light sources, The light source can select one of at least two colors of light and light it.

  A finger position guidance display device according to claim 3 is the finger position guidance display device according to claim 1 or 2, wherein the light source of the finger position guidance display board unit includes a microcomputer and a plurality of light emitters on a base. The surface-mounted LED is provided.

  A finger position guidance display device according to claim 4 is the finger position guidance display device according to any one of claims 1 to 3, wherein the finger position guidance display plate unit has a unit extension connector, The finger position guidance display board unit can be used in succession.

  Since it can be detachably installed on any keyboard instrument, it is possible to practice using the finger position guidance display function with the keyboard instrument you normally use, without having to replace it with a dedicated keyboard instrument.

  Since the surface-mounted multi-color LED capable of turning on a plurality of lights for each keyboard guides the position of each finger, it is possible to perform effective repeated practice in consideration of the accurate finger position.

  With the above function, it is possible to simultaneously display the characteristics of the chord to be pressed and the finger position on the keyboard by color.

  By using a surface-mounted multicolor LED with a built-in microcomputer, the control circuit can be simplified, so that the manufacturing cost can be reduced.

It is a photograph which shows the structure of the finger position guidance display apparatus of this embodiment. It is a plane photograph of a finger position guidance display board unit. It is a photograph which shows cooperation with a personal computer screen and a key press display. It is a photograph which shows an example which displays the feature and finger position of a chord with a color.

Hereinafter, the finger position guidance display device according to the present embodiment will be described with reference to the drawings.
The finger position guidance display device according to the present embodiment is a finger position guidance display device according to claim 4, and as shown in FIG. The finger position guidance display board unit 1 is detachably installed on the keyboard of the keyboard instrument 4.

  The finger position guidance display board unit 1 has a unit extension connector 13 (FIG. 2), and a plurality of finger position guide display board units 1 can be installed (FIGS. 1 and 3). As shown in FIG. 2, the finger position guidance display board unit 1 has a white key light source 11 and a black key light source 12 at positions corresponding to the respective white keys or black keys. As shown in FIG. 3, the keyboard is arranged at the base position of each keyboard to guide the keyboard to be pressed.

  In this embodiment, a surface-mounted LED having a plurality of light emitters and a microcomputer on a base is used as a light source (not shown). The mechanism for finger position guidance is as follows. First, the personal computer 3 executing the performance program transmits the accompanying information of the corresponding note to the control electronic circuit 2 as the music progresses while displaying the score on the display. The control electronic circuit 2 selects a key position to be depressed and a color corresponding to a finger to be used in accordance with the transmitted information, and transmits the information to the LED light source of the finger position guidance display board unit. The transmitted information is finally processed by a microcomputer arranged on the board of the LED corresponding to each keyboard, and a specific color LED is turned on by an instruction from the microcomputer.

  As described above, since the finger position guidance display device uses surface-mounted multicolor LEDs as a light source, it is possible to simultaneously display chord finger position information on the keyboard using different colors. FIG. 4 shows an example of displaying the key depression position of CM7 (Sea Major Seven). Here, the root note is displayed in red, 3 degrees yellow, 5 degrees blue, and 7 degrees green, and guidance is given that the little finger, middle finger, index finger, and thumb should be pressed.
