Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel musical instrument of a type in which a player can play or practice playing by operating fingertip operation parts such as lighted keyboards in the order of their flashing, The case houses an electric sound generating mechanism including a power supply, a sound source, and a speaker, and is equipped with a changeover switch with off-position, practice performance, and normal performance positions, as well as a self-returning polyphonic keyboard. A path for the perforated paper card with scale holes opened in accordance with the music score is created, and an input switch is installed in the path to be turned on when the above-mentioned perforated paper card passes through the scale hole. A key switch is provided at the bottom of each of the above-mentioned keyboards to turn on and energize the above-mentioned sounding mechanism when the key is pressed, and an electric light-emitting means is attached near each keyboard, and each light-emitting means and the card are connected to each other. The input switch provided in the passageway is energized by turning on the changeover switch to the practice performance and normal performance positions, and each scale hole in the perforated paper card is connected to the rear half of the preceding scale hole. The gist is that the first half of the following scale holes are arranged in a horizontal line perpendicular to the direction of travel of the punched paper card.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.In the case 1, electric circuits 2 and 3 formed of a sound source circuit, a tone circuit, a volume adjustment circuit, an amplifier circuit, etc. (detailed explanation will be omitted). ) and speaker 4
and a battery 5, and a changeover switch 7 provided on the outside of the case 1 with an off position, a practice performance position, a normal performance position, and an automatic performance position, a self-resetting keyboard 8 for 10 scales..., and a card feed roll 17 to be described later. A speed adjustment dial 9 is provided on the top surface of the case 1, and a passage 13 for a perforated paper card 12 is formed on the top surface of the case 1 by duplicating the scale hole 11 with the previous scale hole in accordance with the desired musical score. When the perforated paper card 12 is inserted into the entrance of the passageway 13, the movable contact piece 14 contacts the fixed contact piece 15 to turn on the operating switch 16, and the operating switch 16 is turned on. An electric feed roll 17 and a pinch roll 18 are provided to perform a feeding operation only in the position, and a key switch 19 that is turned on when the keyboard 8 is pressed is provided on the bottom surface of each of the keys 8. Each of these key switches 19..., when turned on when the switch 7 is in the practice play or normal play position, produces a tone corresponding to the scale of the pressed key (Do-Re-Mi either) is made to sound by the electric circuits 2 and 3, the speaker 4 and the battery 5, and the perforated paper card is further transported by the feed roll 17 in the passing path 13 before the feed roll 17. The input switch 23 for 10 scales is turned on when the movable contact piece 21 and the fixed contact piece 22 come into contact within the 12 scale holes 11, and turned off at the holeless part of the perforated paper card 12.
. . are provided, and when the input switch 23 . When the electric circuits 2, 3, the speaker 4 and the battery 5 are used to produce sound, and the selector switch 7 is turned on when it is in the practice performance or normal performance position. In this case, the light emitting diode 24 installed on the bottom surface of each keyboard 8 corresponding to the scale of each scale hole 11 to illuminate the light emitting diode 24 is powered by a battery 5, and further Draw a required picture 25 etc. in the margin of the punched paper card 12 and draw this picture 25 etc. on the passage path 13.
The video is displayed as a moving image through a window 26 installed in the ceiling wall of the building.

That is, in the above embodiment, the changeover switch 7 is set to the practice performance and normal performance positions, and the feed roll 17 is set to the practice performance and normal performance positions.
When the perforated paper card 12 is inserted between the pinch rolls 18 through the entrance side of the passageway 13, the keyboard 8 of the preceding scale first lights up and emits light, and then, during the light emission, the next keyboard 8 lights up and emits light. The lighting of the next keyboard continues after the keyboard 8 of the previous ranking goes out until the lighting of the keyboard 8 of the next priority order continues, and these keyboards 8... are played at the musical tempo in the order in which they are played. Since the light flashes, you can practice playing by pressing the keys 8 that light up with your fingertips in the order in which they light up. You can also use the switch 7 to switch between practice playing and normal playing. Perforate paper card 1 in performance position and passageway 13
When 2 is not pressed, the keyboard 8... can be played like a normal organ, and the changeover switch 7 can be set to the automatic performance position, and the leading scale can be played between the forward roll 17 and the pinch roll 18. When a perforated paper card of a type in which the holes and the scale holes of the next rank do not overlap in the advancing direction is pushed through the entrance side of the passageway 13, the sound is automatically generated as the card is fed. It is something that you can enjoy playing.

The present invention is as described above, and by using the method as shown in the embodiment, it is possible to perform performance practice using the luminous guidance of the keyboard, or to stop the luminous guidance and perform normally. In particular, the present invention is such that each scale hole in a perforated paper card is arranged in such a way that the latter half of the preceding scale hole and the first half of the following scale hole are arranged in a horizontal line orthogonal to the direction of travel of the perforated paper card. Therefore, when practicing using the keyboard's light-emitting guidance, the next-ranked keyboard will start emitting light while the corresponding light-emitting keyboard is emitting light, and as a result, the next-ranking keyboard will emit light at the same time as the corresponding keyboard's light emission disappears. Unlike conventional keyboards, the position of the next keyboard can be quickly confirmed while the corresponding key is being pressed, making it easier to play and making the performance smoother.

The musical instruments of the present invention include organs, pianos, accordions, guitars, xylophones, glockenspiels, flutes, trumpets, clarinets, and the like.
