DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. That is, FIG. 1 is a block diagram showing the overall configuration of the present embodiment, and the CPU 1 is required in this musical score editing apparatus based on programs etc. stored in advance in the ROM 2 and data temporarily stored in the RAM 3. Execute all controls. The ROM 2 stores, together with the program, image data of various symbols necessary for musical scores such as various notes, staffs, clefs, key signatures, and time signatures.

The LCD controller 4 includes a CPU 1
The LCD display unit 5 is driven in accordance with the instruction of (1) to display the staff, notes and the like, and at the same time, edit processing of the score composed of the staff and notes is executed. A touch panel 6 is laminated on the upper surface side of the LCD display unit 5, and touch information on the touch panel 6 is input to the CPU 1 via a panel I / O port 7. The sound source 8 generates a musical tone waveform according to an instruction from the CPU 1, and the musical tone waveform is generated by an amplifier 9
Is amplified by and is emitted from the speaker 10.

FIG. 2 shows an external structure of the music information display device according to this embodiment. The device body 11 has a screen 12 formed by laminating a touch panel 6 on the LCD display section 5. It is provided. At the bottom of the screen 12, switches 13 and 14 used for turning on / off the device and adjusting the brightness of the LCD display unit 5 are arranged, and LEDs 15 and 16 corresponding to the switches 13 and 14 are arranged.
Are arranged. On the side of the switch 14, the speaker 10 is built in, and a pen 17 provided separately from the apparatus main body 11 is prepared.

Next, the operation of this embodiment having the above configuration will be described. That is, the CPU 1 starts the operation according to the main flow shown in FIG. 3 when the switch 13 is turned on. Then, first, the LCD controller 4 is controlled based on the image data of the musical notation read from the ROM 2,
The staff notation is displayed on the CD display unit 5 (SA1). This S
By the process of A1, a plurality of staffs are displayed on the screen 12.

Next, it is determined whether or not there is a clef input operation (SA2). Here, the clef input operation is, for example, the operation of drawing "o" on the staff using the pen 17. When the input person draws “◯” on the staff using the pen 17, the touch of the pen 17 at the time of drawing is detected by the touch panel 6 and input to the CPU 1 via the panel I / O port 7. Then, the CPU 1 determines that there is a clef input operation, reads the image data of the treble clef from the ROM 2, controls the LCD controller 4, and executes clef display (SA3). Depending on the processing of this SA3, L
By the operation of the CD controller 4, a treble clef is displayed at the end of the staff drawing the "O".

Next, it is determined whether or not there is a time signature input operation (SA4). This time signature input operation is, for example, an operation of writing the numerator and denominator numbers of the time signature on the staff using the pen 17. That is, for example, if the time signature is 3/4,
Write "3" at the top and "4" at the bottom. As a result, a touch is detected by the touch panel 6 and a numeric value is input to the CPU 1 via the panel I / O port 7. Then, the CPU 1 recognizes the two numbers written above and below based on the number data stored in the ROM 2 and determines that the tone sign input operation has been performed, and executes the time signature display (SA5). ). That is, the image data of the corresponding numeral is read from the ROM 2, and the LCD controller 4 operates according to the read image data, whereby the tone symbol "3/4" is displayed (see FIG. 6).

In this way, after executing the determination processing of SA1 to SA5, the next pen operation processing (SA6) is performed. This pen operation processing is executed according to the flowchart shown in FIG. 4, and first, the pen operation determination is performed (SB
1). In the pen operation determination, it is determined whether the operation performed on the screen 12 by the pen 17 is a “note input operation”, an “edit operation”, or an “end operation”. Here, the “note input operation” means an operation of inputting a note by hand with the pen 17 on the displayed staff, or by specifying a pitch on the staff and then specifying a note length by a numerical value. Is an operation for inputting.

When such a note input operation is performed, the note input operation is detected and input based on the touch signal of the pen 17 input from the touch panel 6 through the panel I / O port 7. Display notes (SB
2). Subsequently, it is determined whether or not there is a note input for one bar in the time signature (SB3), and the loop of SB2 → SB3 is repeated until the note input for one bar is input. Therefore, during this time, by performing a note input operation on the staff, the input note is displayed every time the process of SB2 is executed. When a note for one bar is input, the bar line is automatically drawn (SB4).
By the processing of 4, the bar line is displayed after the last note for one bar.

Subsequently, it is judged whether or not there is a note input for one step (SB5), and until a note input for one step is received,
The loop of SB2 to SB5 is repeated. Therefore, this SB
By repeating the loop of 2 to SB5, the notes input during this period are sequentially displayed, and the bar line is displayed at the time when there is a note input of one bar. And
If there is a note input for one step, proceed from SB5 to SB6,
Determine whether or not there is a music score completion operation.

The completion operation of this musical score is an operation of writing a line in parallel with the bar line drawn automatically last by the operation of the pen 17. And such a pen 17
If there is no operation by, the clef and key signature are automatically displayed at the beginning of the next stage (SB8), and the process from SB2 is repeated. Therefore, until the completion operation is done,
The loop of SB2 to SB8 is repeated, the notes input during this are sequentially displayed, the bar line is displayed when there is one bar of note input, and the bar is displayed when there is one row of note input. By changing the stage, the clef etc. is automatically displayed. Then, when the completion operation is performed, SB6 to S
Proceeding to B7, the end line is drawn, and by the processing of SB7, the end line is displayed at the last part of the final stage.

On the other hand, when it is determined that there is an "editing operation" when the pen operation determination is made in SB1,
Go from SB1 to SB9. Here, "editing operation" means
It is any one of an operation of writing a numerical value on the screen by operating the pen 17, an operation of specifying a range with parentheses, an operation of writing a symbol, and an operation of writing a character. Then, if there is any of these operation modes, the contents are judged at SB9, and any one of the processes 1 to 4 is executed according to the judgment result (SB10 to SB13).

That is, the processing 1 (SB10) when the content of the editing operation is "numerical value" is executed according to the flow chart shown in FIG. 5, and the position where the numerical value is written is displayed on the displayed musical score. Recognize (SC1). Further, the symbol entered before the recognized numerical value is recognized (SC2) and the numerical value is recognized (SC3). Next, after the processing according to the position of the numerical value, the symbol and the recognition result of the numerical value is executed (SC4), the display is switched based on the display data generated by this processing (SC5).

The contents of this processing 1 will be described more specifically. That is, as shown in FIG. 6A, the pitch F1
In the state where the quarter note is displayed, if "/ 4" is written after the note by operating the pen 17 as shown by the dotted line in FIG.
It is recognized that the position, that is, the numerical value "4" is after the quarter note of the pitch F1 (SC1). Next, the symbol "÷" before the numerical value "4" is recognized and (SC
2), the numerical value "4" is recognized (SC3). Then, in the processing (SC4) corresponding to the next recognition result, SC1
Based on the result recognized by SC3, the pitch length of the quarter note of the pitch F1 is divided by “4” to obtain the pitch of the pitch F1 of 16
Get the quarter note. Then, the quarter note of the pitch F1 to be changed is erased, and the display switching (SC5) for displaying the sixteenth note of the pitch F1 obtained in SC4 is executed. As shown in C), the quarter note of the pitch F1 that has been displayed so far is changed and displayed to the 16th note of the same pitch.

Further, as shown in FIG. 7A, when the sixteenth note of the pitch F1 is displayed, the pen 17 is operated by the operation of the pen 17 as shown by the dotted line in FIG. 7B. If "x2" is written after the note, it is first recognized that the position of the numerical value "2", that is, the numerical value "2" is after the 16th note of the pitch F1 (SC1). Next, the symbol "x" before the numerical value "2" is recognized (SC2) and the numerical value "4" is recognized (SC3). Then, in the processing (SC4) according to the next recognition result,
Based on the result recognized in SC1 to SC3, the pitch F of the 16th note of the pitch F1 is multiplied by "2" to obtain the pitch F
Get the eighth note of 1. Next, the 16th note of the pitch F1 to be changed is erased, and the pitch F1 of 8 obtained in SC4 is deleted.
By executing the display switching (SC5) for displaying the quarter note, as shown in (C) of the figure, the 16th note of the pitch F1 which has been displayed so far is changed to the eighth note of the same pitch. The note is changed and displayed.

Further, as shown in FIG. 8A, when the quarter note of the pitch F1 is displayed, the pen 17 is operated by the operation as shown by the dotted line in FIG. 8B. If "÷ 3" is written after the note, it is first recognized that the position of the numerical value "3" is after the quarter note of the pitch F1 (SC1). Next, the symbol "÷" before the numerical value "4" is recognized (SC2), and the numerical value "3" is recognized.
Is recognized (SC3). Then, in the processing (SC4) according to the next recognition result, the pitch length of the quarter note of the pitch F1 is set to "3" based on the recognition result of SC1 to SC3.
By dividing by, a triplet with pitch F1 is obtained. Next, the quarter note of the pitch F1 to be changed is erased, and the display switching (SC5) for displaying the triplet of the pitch F1 obtained in SC4 is executed, thereby As shown in C), the quarter note of the pitch F1 that has been displayed so far is changed and displayed as the triplet of the same pitch.

When the content of the editing operation is "parentheses", the process 2 (SB11) is executed according to the flow chart shown in FIG. 9, and the range enclosed by the parentheses is recognized on the displayed musical score. Yes (SD1). Then, the figure drawn next is recognized (SD2), and it is determined whether or not the recognized figure is "x". If the recognized figure is "x", the area recognized in SD1 is erased (SD4). However, if the recognized figure is not "x", it is determined whether it is """or not (SD5). If it is"", the value in the parenthesis is set in the parenthesis. Copy (SD6).

That is, if the determination of SD5 is YES, two parentheses, that is, the parenthesis before the object whose range is recognized in SD1 and the parenthesis after the determination in SD5, are written. Become. Therefore, in such a case, the notes or the like existing in the preceding parentheses are copied to the range enclosed by the subsequent parentheses. If the determination of SD5 is NO and the figure drawn next is not """,
It is determined whether or not it is a numerical value (SD7), and if it is a numerical value, the symbol described before the numerical value is recognized (SD
8). Then, according to the numerical value and the symbol, the note in the range enclosed by the parentheses is transposed (SD9), and SD is SD in the subsequent SD10.
4, the result of each processing performed in SD6, SD9 is displayed.

The contents of the process 2 shown above will be described more specifically. That is, as shown in FIG.
When the quarter note of the pitch E1 is displayed, if the note is enclosed in parenthesis as shown in FIG. 7B, the range within the parenthesis is recognized (SD1). Further, when the x mark is entered in the parentheses, this is recognized (SD2), and it is determined that it is the x mark (YES in SD3). Subsequently, the area within the parentheses is erased (SD4), and as a result, the displayed quarter note of the pitch E1 disappears as shown in (C) of the figure.

Further, as shown in FIG. 11A, in the state where the notes are displayed over a plurality of stages and a plurality of measures, the final measure is parenthesized as shown in FIG. When enclosed, the range for one bar in parentheses is recognized (SD
1). In addition, if the X mark is entered in the parentheses, this is recognized (SD2), and it is determined that it is the X mark (SD3).
Is YES). Then, the area within the parentheses is erased (SD
4) As a result, the displayed last measure disappears as shown in FIG.

Further, as shown in FIG.
In the state where notes are displayed over multiple lines and multiple measures, first, as shown in (B) of the figure, if the range with the upper measure is enclosed in parentheses and the range is specified, one measure in the parentheses The range is recognized (SD1). Next, if the range is specified by writing """on the lower staff without writing the X mark, this is recognized (SD2) and it is determined that it is""" (SD5 is YES) .Continuingly, the values in the opening brackets, that is, the two eighth notes of pitch G1, the quarter notes of pitch A1, and the quarter notes of pitch B1 in the upper brackets are in the lower brackets. (SD6), so that as shown in (C) of the figure, on the lower staff,
Two eighth notes with pitch G1, quarter notes with pitch A1, and quarter notes with pitch B1 are displayed.

Further, as shown in FIG. 13A, when a note is displayed over a plurality of stages and a plurality of measures, it is displayed in the lower stage as shown in FIG. 13B. When the quarter notes of the pitches B1, C2, B1, and A1 that are present are enclosed in parentheses, the range is recognized (SD1). Next, if "-1" is written without writing an X mark and "", this is recognized (SD2), and it is discriminated that it is a numerical value (SD7 is YES). Subsequently, the symbol "-" before the numerical value is recognized (SD8), and the transposition is executed according to the numerical value and the symbol "-1" (SD9).

That is, in this SD9, when the symbol is "-", transposition is performed by lowering the pitch of the note in parentheses according to the numerical value. Therefore, in the case of this example, the quarter notes of the pitches B1, C2, B1, A1 are lowered by 1 degree to become the pitches A1, B1, A1, G1, and as shown in (C) of FIG. These pitches A1, B1, A1,
The quarter note of G1 is displayed instead of the quarter note of the pitches B1, C2, B1, and A1. When the symbol is "+", transposition is performed by raising the pitch of the note in parentheses according to the numerical value.

When the content of the editing operation is "symbol", the process 3 (SB12) is executed according to the flowchart shown in FIG.
E1). After that, it is determined whether or not the symbol is upward opening (SE2), and if it is upward opening, the position is recognized (SE3). Next, based on the result confirmed in SE3, it is determined whether or not the upward opening symbol is entered between the notes (SE4), and if it is entered between the notes, the interval is set to 1
Opening by the amount of note insertion (SE5), an area in which one note can be inserted is formed between the notes corresponding to the symbols. However, if the symbol was not a between notes, it is determined whether or not the inter-bar (SE6), 1-measure opening when a between bars (SE7), thereby on stave An area for one bar is formed. On the other hand, when the symbol is not the upper opening, it is determined whether it is the lower opening, and when it is the lower opening, the process for closing the gap is executed (SE9),
At the next SE10, the processing results performed at SE5, SE7, and SE9 are displayed.

The contents of the process 3 shown above will be described more specifically. That is, as shown in FIG.
When the quarter note of the pitch F1 and the quarter note of the pitch A1 are displayed, if a “∨” is written between the both notes as shown by the dotted line in FIG. Is recognized (SE1). Since this symbol “∨” is open upward (YES in SE2), its position is confirmed (SE
3) Further, since "∨" is between the quarter notes (YES in SE4), a process for opening one note is executed (SE5). Therefore, after the processing of this SE5 is executed, SE10 is executed, so that (C) of FIG.
As shown in, the display state in which one note is vacant between the quarter note of the pitch F1 and the quarter note of the pitch A1.

Therefore, if the note input operation for writing the eighth note of the pitch F1 is performed in the area vacated by this one note, as shown by the dotted line in FIG. SB2
The note input operation is detected and displayed at. Therefore, as shown in (E) of the figure, the eighth note of the pitch F1 is displayed between the quarter note of the pitch F1 and the quarter note of the pitch A1. Also, as shown by the dotted line, if you write "∧" between the eighth note of pitch F1 and the quarter note of pitch A1, this symbol opens downward (YES in SE8). Is executed (SE9), and the execution result is displayed in SE10. As a result, as shown in (F) of the same figure, the eighth note of the pitch F1 and the quarter note of the pitch A1 are separated. The display becomes narrower.

Further, as shown in (A) of FIG. 16, in a state where notes are displayed over a plurality of measures, as shown by dotted lines in (B) of FIG. By writing "∨", the figure of this symbol is recognized (SE1). Since this symbol “∨” is open upward (SE2 is YES),
The position is confirmed (SE3), and since "∨" is between measures (SE4 is NO, SE6 is YES), 1
Processing for opening measures is executed (SE7). Therefore,
After the processing of SE7 is executed, SE10 is executed, and as shown in (C) of the figure, an area for one bar where no note exists between the bars where each note exists. Is displayed.

Further, as shown in FIG. 17 (A), in the state where there is a blank measure in which no note exists, as shown by a dotted line in FIG. 17 (B), "∧" is placed above the blank measure. If you enter, the figure of this symbol will be recognized (S
E1). Since this symbol "∧" is a downward spread (SE2
Is NO, SE8 is YES), the process of closing the space is executed (SE9), and the execution result is displayed in SE10. As a result, as shown in (C) of FIG. The existing bars are displayed continuously.

Further, the process 4 (SB13) when the content of the editing operation is "character" is executed according to the flowchart shown in FIG. That is, the input character is recognized (SF1) and the data corresponding to the recognition result is displayed (SF2). Next, it is determined whether or not there are a plurality of candidates for the data corresponding to the recognition result (SF3), and if there is not a plurality of candidates, the display state of the data in SF2 is maintained (SF7).
However, when there are a plurality of candidates, a plurality of data which are all candidates are displayed (SF4), and the pressure selection by the pen 17 is read (SF5). Then, other candidates than the one selected by the pen 17 are erased (SF6), and the selected candidates are displayed (SF6).

That is, while the score shown in FIG. 19A is being displayed, as shown by the dotted line in FIG.
When the character "e" is input, the input character is recognized (SF1). Then, as shown in FIG. 7C, the data "Mod" corresponding to the recognized "Mode" is recognized.
