FIG. 1 shows an example of a display screen at the time of editing. At the bottom line, a mouse operation area for changing the page, row, column, and bar number is set. For example, when changing the page number, the image 21 of the sliding knob is dragged with the mouse. , 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 FIG. 1, reference numerals 24, 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.

A frame 31 indicates a bar display area, and a plurality of parts are simultaneously displayed for each bar. Mouse cursor 2
7 is a dotted line 33 with a measure width ratio of 10% in the measure display area.
When the cursor is moved to an area 29 which is on the left of the area (not shown with a dotted line) and at the staff or in the vicinity of the staff, the cursor which was a triangle and a vertical line up to that point is changed to a triangle 2 as shown in FIG.
It changes to 7 and a frame 30 surrounding the bar. The position of this frame can be easily read by the left and right scales 32. Normally, music symbols such as notes are displayed to the right of 10%, and must be clicked with the mouse for editing.
Since the left side is not used for editing, the area is used. When the mouse is dragged in the state as shown in FIG. 1, only the frame 30 moves up and down correspondingly, and when the drag is completed and the finger is released, the bar corresponding to the position of the frame at that time moves. Is displayed. Therefore, when it is desired to set the staff at a predetermined interval, the mouse may be dragged so that the frame is at a predetermined position with reference to the scale. 34 is 1
This is a figure that represents one line, and expands and contracts as the staff moves.

Although the embodiment has been described above, the following modifications are also conceivable. The shape of the cursor at the time of the staff interval change processing is not limited to the frame, and any shape such as a horizontal line or a cross line can be used as long as the value of the scale is easy to read. Although an example has been shown in which only the frame is moved at the time of dragging and the staff display is updated at the end of the dragging, the staff display may be updated each time in step S64 of FIG. Further, as a method of inputting the moving distance, a method of clicking once, moving the mouse and clicking again without dragging may be used. Although the position of the staff can be set continuously, it may be set discretely, for example, in units of several millimeters. The scale is displayed corresponding to the unit, and the scale is moved in scale units. It may be. In this way, the intervals can be accurately aligned.

While the frame is being displayed, the vertical position information may be displayed corresponding to the frame or numerically in a specific area of the screen. When it is necessary to click the entire staff by the editing function, the area for performing the staff interval change processing may be, for example, a portion on the left side of the bar in the range 29 in FIG. The vertical position information is not limited to the relative position in the vertical direction from the printing reference point, and may be based on the staff of the first part and may represent the distance between the staff of the first part and the staff of each part. Alternatively, it may be defined as the distance between the staff of each part and the staff of one part above or below it. In addition, as a method of updating the vertical position information, for example, when the staff of the second part is moved, all staffs of the third part and thereafter can be changed, or only the staff of the second part can be changed. The vertical position information can also be updated so that is moved.

The line spacing (the interval between the staff of the lowermost part of the upper row and the staff of the first part of the lower row) is fixedly set in accordance with the paper size information. A plurality of lines can be displayed, and the line spacing can be arbitrarily changed and displayed and printed in the same manner as in the embodiment. 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.

[0026]

As described above, according to the present invention, the interval between the staffs can be set by referring to the scale with the mouse. Therefore, the interval can be easily and accurately set to a desired value. There is an effect that the intervals between the staffs can be aligned.
