Performs processing to convert data into a form that can be processed by the device. Step S
At 14, it is checked whether the end is instructed or not.
If the determination is negative, the process returns to step S3, but if termination is instructed, the program ends.

FIG. 5 is a flowchart showing details of the editing process in step S9 of FIG. In step S40, the bar number is set to 1. In step S41, the measure specified by the current measure number is displayed on the screen as an image, and an instruction is input.
In step S42, it is checked whether or not the input instruction is a measure number change. If the instruction is affirmative, the process shifts to step S43 to update the measure number. This processing will be described later. After the processing in step S43, the process returns to step S41, and the contents of the measure having the new measure number are displayed as an image.

In step S44, it is checked whether or not the instruction is to add a bar. If the instruction is affirmative, the process shifts to step S45. In step S45, a process of adding the number of bars is performed. The total number of measures of information, each part information and measure information are updated. Step S46
In, it is checked whether or not the instruction is a measure deletion,
If the result is affirmative, the process shifts to step S47. In step S47, the number of measures is deleted, and the total number of measures, each part information and measure information of the header information in FIG. 3 are updated.

In step S48, it is checked whether or not the instruction is to change the bar width. If the result is affirmative, the flow shifts to step S49. In step S49, a desired bar width is designated by a mouse or the like. The width ratio data of the bar information of No. 3 is updated. Also, the width change flag is set to ON. In step S50, it is checked whether or not the instruction is to change the staff interval. If the determination is affirmative, the process proceeds to step S51. In step S51, the vertical interval for determining the interval between the staffs in each part information is determined. The location information is updated.

FIG. 6 is a flowchart showing details of the bar number changing process in step S43 of FIG. In step S60, for example, it is checked whether or not the clicked portion of the page number on the screen has been clicked with the mouse. If the result is affirmative, the process proceeds to step S61. In step S61, the page number is updated. This will be described later with reference to FIG. If step S60 is negative, step S
In step S62, it is checked whether or not the user has clicked on a line number change portion on the screen. If the result is affirmative, the process proceeds to step S63. In step S63, the same as the above-described page number change operation is performed. Update the line number by the operation. If step S62 is negative, the process moves to step S64, and in step S64, it is checked whether or not the column number change location on the screen is clicked.
If affirmative, the process proceeds to step S64, and the column number is updated by the same operation as the above-described page number change operation.

After the processing in step S61, 63 or 65, the flow shifts to step S66 to calculate a bar number from the updated page, line and column numbers. In this calculation, since the bar width may be changed, for example, the number of lines per page is determined from the paper size and the number of parts, and the bar width is sequentially added from the first line of the page. If the maximum width of one line is exceeded, the bar number of the target page, row, or column can be obtained and the bar number value can be updated by moving to the beginning of the next line and repeating the addition of the bar width. . If step S64 is negative, the process moves to step S67, where it is checked whether or not the changed bar number is clicked on the screen. If the result is affirmative, the process moves to step S68. The measure number is updated by the same operation as the number change operation. In step S69, the same operation as in step S66 is repeated until the updated bar number is reached, and the page, row, and column numbers at that time are obtained and updated.

FIG. 1 shows an example of a display screen at the time of editing. In the bottom row, a mouse operation area for changing the page, row, column, and bar number is set. For example, when changing the page number, drag the image 21 of the sliding knob with the mouse (button (While pressing and moving), the page number can be changed continuously. The position of the knob changes corresponding to the number. By clicking the squares 22 or 20 on both sides of the knob, the page number can be incremented by +1 or -1. Further, by clicking the page number display area 23, the page number can be input from the keyboard 8. In addition, 2 in FIG.
Reference numerals 4, 25, and 26 denote display areas for a row number, a column number, and a bar number, respectively. Reference numeral 27 denotes a mouse cursor, and reference numeral 28 denotes a knob image for scrolling the screen up and down by a mouse. The main menu is displayed on the top line, and the main menu can be selected by clicking this with the mouse.

FIG. 8 is an explanatory diagram showing an example of a bar display form on the edit screen. Conventionally, as shown in (c), the bar at any position has the same form separated by a bar line on both sides. At first glance, it is determined whether the bar is at the head of the line or at the end. It could not be determined. In the present invention, for example, in the case of a bar at the head of a line, as shown in FIG.
Is displayed, and if there is a bar following that line, the staff is displayed extending beyond the bar line. FIG. 8B is a display example of the last bar of the line. In FIG. 1, an example of the first bar of the score data of three or more parts is displayed, and a bar number is also displayed at the upper left of the bar.

FIG. 7 is a flowchart showing details of the printing process in step S11 of FIG. In step S80, an instruction is input. In step S81,
It is checked whether or not the instruction is a print page change, and if affirmative, the process proceeds to step S82 to perform a print page change process.
In step S83, it is checked whether or not the instruction is to execute printing. If the instruction is affirmative, the flow shifts to step S84 to execute printing processing. In this printing process, the musical score image data of the entire designated page is created in the memory,
This is performed by transferring the image data to a printer.

In step S85, it is checked whether or not the instruction is to display an image screen. If the instruction is affirmative, the flow shifts to step S86 to perform image display processing.
In this process, first, for example, a staff image of a page specified in a tone such as gray is created on a white background, and then an image of a musical symbol such as a musical note is synthesized in a tone different from the staff such as black. . Then, the image is further compressed to a required size, and the entire image for one page is displayed on one screen. In this way, even if the image of the staff and the image of the music symbol overlap, both can be recognized due to the difference in color tone, and the image can be recognized even if the image is reduced so that all the pages fit on one screen. In step S87, it is determined whether or not the instruction has been completed. If not, the process returns to step S80.
If affirmative, the printing process ends.

Although the embodiment has been described above, the following modifications are also conceivable. In the operation of changing the bar number or the like with the mouse, a function of changing the bar number to the first or last number by clicking a specific area of the screen may be added. The coordinate information input device is not limited to a mouse, and any device such as a trackball, a light pen, and a touch panel can be used. The magnification of the bar display area may be arbitrarily changed, and may be reduced so that two or more measures can be displayed at the same time.
You may make it printable by reducing.
