DETAILED DESCRIPTION OF THE INVENTION The present invention provides a musical score printing device Kll that prints musical notes on print paper suitable for creating musical scores.

2. Description of the Related Art Conventionally, there has been a musical score printing device that prints a musical piece played automatically on a keyboard as a musical score on ordinary paper such as 41fIa or 15-size paper. but,
This type of device prints musical scores in several stages on ordinary paper as mentioned above, and the printing device itself is 1Illll.
Ke), was graduating from Pusto High School. In addition, there is also a sheet music printing device that is equipped with a roll of printing paper and feeds the printing paper through a sound electric progression tc* to print musical scores one after another. The following disadvantages were that the musical score expansion was extremely long and continuous, and 1) it was difficult to read.

This invention was developed in view of the above drawbacks, is inexpensive,
Moreover, it is an object of the present invention to provide a musical score printing device that enables the creation of clear musical scores.

In other words, according to IA Ming, a strip of printing paper is prepared on which nine staffs of length corresponding to a predetermined number of measures are printed consecutively through a blank space of a predetermined length. Print notes on the printing staff based on key information indicating the length and note length information, and empty-feed the printing paper by a predetermined length of the blank section every time the preset number of bars are printed. That's what I do.

The present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of an electronic musical instrument having a musical score printing device according to the present invention, in which when musical tones are generated based on keyboard performance or automatic performance, the generated musical tones are printed on print paper once every 41 days. be.

First, a case in which keyboard performance is performed on this electronic musical instrument will be explained. In this case, keyboard 1 generates key information (key code) xC indicating the pressed key and key-on signal KON indicating whether the key corresponding to mosquito key code KC is pressed in response to a key pressed on keyboard 1. do. The key code XC is
For example, as shown in Table 1, the 2-bit octave code 1. l, and a 4-bit notebook N4 representing the noble name of Ebisu within one octave. N.

, N, , N, is a 6-bit binary coded signal.

A first musical tone forming circuit 2 forms a musical tone signal based on the key code KC generated from the keyboard 1, and sends this signal to an amplifier 3.
, and add it to speaker 4. As a result, the keyboard 4 produces a sound corresponding to the key pressed on the keyboard 1.

The autorhythm device 56 is used for automatic rhythm performance, and includes a rhythm selection switch (not shown).
The rhythm tone signal tube tempo oscillator 6 displays various rhythm instrument sounds corresponding to the rhythm selected by the tempo oscillator 6. This rhythm sound signal is also amplified by the amplifier 3 in the same manner as described above, and is emitted by the speaker 4 as a rhythm sound.

On the other hand, the key-on signal KON generated from the keyboard 1 is applied to the note length detection circuit 7. The note length detection circuit 7 receives other inputs -
Tempo oscillator 6-ip and tempo clock CL are added, but the tempo clock 'rc is added to the key-on time.
, L, the note length data t-
By counting the tempo clock TCL generated and added to the key-off time, the note length data of the rest is generated.

Note that this note length detection circuit 7 is configured to correct the count value when the count value includes an error and generate note length data corresponding to the corrected count value.

In other words, if the regular count value corresponding to a quarter note is, for example, n, the regular count value is Note length data corresponding to power and runt values.

There is a possibility that this will be output. Further, the note length detection circuit 7 outputs a data center timing signal Vr at the time when the note length data is outputted. These note length data and data output timing signal are applied to the key code KC outputted from the keyboard 1 to the selector 8.

Next, we will explain how to automatically perform this electronic music. In the case of ζO, first turn on the automatic performance switch 9. From this, the tempo clock CL generated from the tempo oscillator 6 is applied to the read control circuit 10.

The entry/exit control circuit 10 sequentially reads out the key code KC and note length data previously stored in the note memory 11 from the automatic/practical data memory 11 according to the input tempo clock iCL.

The key code KC read from the memory 11 is applied to the tone forming circuit 2. The musical tone forming circuit 2 forms a musical tone signal based on the input key code KC, and applies this signal to the speaker 4 via the amplifier 3.

As a result, the sleigh force 4 is set to the automatic performance data memo IJI.
In response to the IK stored data, the automatic performance data memory 11 outputs the note length data and key code KC to the input of the selector 80B, and the readout control section 10 reads the note length data and key code KC from the automatic performance data memory 11. At the timing when the long data is output, the data output timing signal DT is sent to the B input of the selector 8. When printing notes corresponding to the generated musical tone on the print paper, it is determined whether the generated musical tone is caused by the keyboard performance or not. The movable contact piece 12a' of the selection switch is connected to the contact point 12b or the contact point 12C depending on the type of selection switch. In other words, the selector 8 selects the MU input when the signal @l' is applied to the A input select terminal 8, and selects the B input when the signal 11'' is applied to the SB select terminal. When the long data, key code KC, and data output timing signal D〒 are applied to the five inputs of the selector 8, connect the movable contact piece 12a of the selection switch to the contact 12b and send the signal @1'' to the A person select terminal SA.
In addition to K, note length data, key code KC,
If data output timing signal input is applied to selector 80B manually, select switch yf12O movable guard 121
Meeting point 12CKIII! Then, the signal °1"tB is applied to the input select terminal 111.

The note length data selected by the selector 8 is applied to the note rest information conversion path 13> and the minor II/4 measure end detection circuit 14, and the key food KC is applied to the note position control section 17 of the printing device 15. Data output timing signal D
te is the note rest of the printing device respectively **Control unit 16
, are added to the note position control section 17 and paper feed control section 18.

The note rest information conversion circuit B outputs note rest information indicating predetermined notes and rests to the note rest type control unit 16 of the printing device 15 based on the input note length data. Also,
The measure/four-measure end detection circuit 14 has an accumulator, and detects the end of a measure and the end of four measures by sequentially accumulating input note length data. As a result, the measure 74 measure end detection circuit 14 generates a measure end pulse Ptt every time the measure ends.
'', and a 4-measure end pulse P is applied to the paper feed/control section 15 of the printing device each time every 4 measures are completed.

The note rest type control unit 16 includes a read-only memory (ROM) that stores in advance dot information indicating a plurality of notes and rests corresponding to the note length. Read appropriate dot information based on the note rest information added from the information conversion circuit 13,
This is output to the printer 19. In addition, the note position control section 17 controls the position of the read dot information on the staff based on the key code KCK added when the data output timing signal DT is input. Based on this, a position control signal is applied to printer D. Further, the paper feed control unit 18 controls the feed amount of print paper set in the printer 19, and the data output timing signal DT,
A feed control signal is applied to the printer 19 based on the bar end pulse P and the 4 bar end pulse P4. The paper feed control unit has a delay circuit and is configured to output a feed control signal after a note or a rest is printed on the print paper.

Here, the print paper set in the printer 19 will be explained with reference to FIGS. 2 and 3.

The print paper 200IN is rolled up in a KO-ru shape as shown in Figure 2, and the print paper 200IN side has a
As shown in a), the length corresponds to 4 measures with the IO blank space 4 in between (in this example, the G note -
The top and bottom notes are printed on the IIO grand staff →. This length LQ large - 6t vertical lines are printed on the table to divide the Ooka cost into 4 measures, and a perforation is formed in the center of the blank area 21 for separating the print paper. ing. On the other hand, as shown in #i and FIGS. 2-) on the back side of this printing paper, adhesive coatings are applied to both upper and lower ends thereof, and a thin removable cover 24 is provided on the adhesive 22.

In this way, since the above-mentioned stave is pre-printed on the print paper, if you want to print the musical score on this print [20], it is necessary to display one line of paper feed control according to the printed staff. .

The paper feed control unit 18 outputs a feed control signal to the printer 19 so as to perform a feed according to the printed paper and the staff printed on the printer 19, and when a data output timing signal DT is inputted, It outputs a feed control signal corresponding to a predetermined note interval, and when a measure end pulse P is input, it outputs a feed control signal corresponding to the distance from the current print position to the next measure start position. Note that the above distance is set in advance to be 9 measures @ (L/4 in this example) Δ・
It can be easily calculated by subtracting * and @ to print the notes of one measure. Also, the bar end pulse -
When P and the 4th bar end pulse P4 are input simultaneously, the bar end pulse PIK@ is first output, and the feed control signal corresponding to the distance from the current print position to the 4th bar end position is output in the same way as above. Then, a 4-bar end pulse P and a feed control signal corresponding to the long cell 1 of the blank section 21 (see FIG. 3(a)) are output.

Therefore, the printer Rei prints notes and note tubes on the print paper 200 based on the dot information indicating notes and rests added from the note rest type control section 16 and the position control signal added from the note position control section 17. At the same time, the printing paper is fed based on the above-mentioned feed control signal applied from the paper feed control unit each time printing of the notes and rests is completed.

The print paper on which the Qin calligraphy was finally printed in this way is separated at the perforation n for separation on the print paper, and the back cover is peeled off, and the backing paper 24 is placed as shown in Figure 4. Paste) to attach. From this K, it is possible to create a musical score with multiple stages.

Note that the number of seasons in one stage is not fixed in the above embodiment, and can be set to various numbers. Further, the vertical lines separating bars may be printed every time a bar ends. Further, in this embodiment, the grand staves representing the treble clef and bass clef staves are printed in advance on the print paper, but the invention is not limited to this, and other staves may be printed, and even only the treble staff may be printed.

As explained above, according to the present invention, the sheet music to be printed only needs to be printed in one stage, that is, it is only necessary to feed the roll-shaped printing paper according to the progress of the music and print the sheet music one after another, so that an inexpensive sheet music printing device can be used. Furthermore, it is easier to read the music if the final printed strip of printing paper is cut out for each set number of measures, and the separated printing paper is attached to a mount or the like in several stages. You can create musical scores.
