Description

[Detailed Description of the Invention] This invention relates to a typewriter that prints characters based on pitch data using an electronic musical instrument or the like.

Conventional typewriters, whether mechanical or electronic, use a dial or character keys to select and print characters.

On the other hand, for electronic musical instruments, devices are being put into practical use that can print notes or rests on the staff based on pitch data and note length data input from the keyboard, and create musical scores according to the content of the performance. .

However, if it is desired to print lyrics, for example, on a musical score created by such a musical score creation device, a separate typewriter must be used to print the lyrics.

In order to solve these problems, this invention uses an electronic musical instrument that has pitch data generation means or uses pitch data from musical instrument performance sounds, human voices, etc. to generate various characters. The purpose of the present invention is to provide a typewriter capable of printing.

Therefore, the typewriter according to this invention generates pitch data in response to pitch-discernable input such as key operations, musical instrument sounds, voices, etc., converts the pitch data into character data, and uses the character data to generate pitch data. It is designed so that characters can be printed on it.

An embodiment of this invention will be described below with reference to FIGS. 1 and 2.

This embodiment is a typewriter that can both create musical scores and print characters using an electronic keyboard instrument.

Fig. 1 shows its appearance. 1 is an electronic keyboard instrument, and a printer 2 is connected to input the pitch data generated by the electronic keyboard instrument and print characters, etc.
A typewriter based on this idea is constructed.

The electronic keyboard instrument 1 includes a keyboard device 3 shown in FIG. 2, which includes a keyboard 3a and a pitch data generation circuit that generates pitch data of a scale corresponding to each key. , a musical tone generator 4 that generates musical tones based on pitch data DS generated by the keyboard device 3 in response to key operations, a speaker 5, and the like.

Note that the gate circuit 6 shown in FIG. 2 is provided so as to be able to stop the generation of musical tones.
It is controlled by a switch 13, which will be described later, and controls the passage of pitch data DS to enable musical tone generation.

As shown in FIG. 1, the printer 2 includes a power switch 11, a paper feed switch 12, a print mode selection switch 13, a print paper holder 14, and the like. 15 is printed paper.

Inside the printer 2, as shown in FIG. 2, there are two gate circuits 16 and 17, and a character data generation circuit that converts pitch data DS inputted through the gate circuit 16 into character data DC. 18 and
Pitch data input via gate circuit 17
A musical score data generation circuit 19 that converts DS into musical score data DM, and a printer control that is a printing means that prints characters or marks musical scores based on character data DC or musical score data DM generated by each of these circuits. 20 and a printer drive section 21.

The keyboard device 3 of the electronic keyboard instrument 1 is used as a pitch data generating means, and the pitch data DS generated thereby is input to date circuits 16 and 17, respectively.

When the print mode selection switch 13 is in the neutral position, it is in the "off mode", and the gate circuits 16 and 17 are both closed and do not allow the pitch data DS to pass through, so neither printing nor marking is performed.

When the print mode selection switch 13 is set to "character mode", the gate circuit 6 is closed via the inverter 22 and the generation of musical tones is stopped. In addition, the gate circuit 16 opens and the pitch data DS is input to the character data generation circuit 18, converted to character data DC, and input to the printer control unit 20, so that the keyboard 3
The character corresponding to the key pressed in a is printed paper 15
is printed on.

Therefore, if the correspondence between each key on the keyboard 3a and a character is determined in advance, any character can be typed by pressing a key on the keyboard 3a.

When the print mode selection switch 13 is set to "score mode", the gate circuit 17 opens and the pitch data DS is input to the score data generation circuit 19, converted to score data DM, and input to the printer control unit 20, so that the keyboard The performance result of 3a is marked on the staff as notes and rests, and the musical score is printed out.

According to this embodiment, a musical score can be created by playing on the electronic keyboard instrument 1, and characters such as lyrics and notes on performance expression can be typed onto the musical score.

In addition, the note name of each key on the keyboard 3a (C, D, E...
) or scale names (C, R, E, etc.) are generated by the character data generating circuit 18, it is also possible to type the performance tones by note name or scale name.

Note that the character data generation circuit 18, which is a pitch data/character data conversion means, and the score data generation circuit 19, which is a pitch data/score data conversion means, are as follows:
It can be easily created using read-only memory (ROM). In addition, these can be used as electronic keyboard instrument 1.
Alternatively, the musical score data generation circuit 19 may be omitted so that only characters can be printed.

Furthermore, although it is convenient to use the keyboard device of an electronic keyboard instrument as a pitch data generating means, the present invention is not limited to this; a separate keyboard device may be provided, and the sound of an instrument or human voice can be recorded using a microphone. Alternatively, the pitch data may be generated by inputting a frequency and determining the frequency.

In this way, it becomes possible to type the performance or singing of natural instruments such as the piano, string instruments, wind instruments, etc. using pitch names or scale names, or to type sentences using these instruments.

As explained above, the typewriter invented by this invention converts pitch data into character data and prints it, so it is possible to easily make a typewriter using an electronic keyboard instrument, and it can also be used as a musical score creation device. The printer control unit and drive unit can also be used together.

You can also check whether you have typed correctly by checking the pitch, and you can also type using musical instruments or voice.
