Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a musical score block making apparatus, and more particularly to a musical score plate making apparatus using a computer.

(Prior Art) Unlike general books, music scores use many staves, musical notes, and other special symbols, and therefore the composition for printing this music score is often a manual task. That is, the warp creator draws the staff by hand on the warp paper, imprints the note at a predetermined position using a woodblock in the shape of the note, tie,
It is common to perform the work of writing special symbols such as slurs by hand.

(Problems to be Solved by the Invention) However, the conventional manual production of the score block requires a great deal of labor. It is also difficult to correct,
The process of making a block copy is also complicated, and it took about 5 to 10 years to become a skilled full-scale plate creator.

In recent years, various software for allocating musical scores on a display has been devised in CAD systems such as personal computers. However, all of these software are intended for automatic performance by a personal computer, not for printing score. Therefore, the size of the staff is uncertain and there is a limit to the equal allocation, and not all fonts necessary for printing are provided.
Further, although it is possible to make a hard copy of the musical score surface allocated on the display, this hard copy has a very low resolution and is unsuitable for use as a block copy for printing.

Therefore, it is an object of the present invention to provide a music composition block creating apparatus capable of easily creating a clear music composition block.

[Structure of Invention]

(Means for Solving the Problems) The present invention is provided in a musical score block creating apparatus, a display device for displaying a musical score surface, an input device for inputting instruction data regarding allocation of the musical score surface, and an input device. A score processor for allocating score surfaces based on the generated data and displaying the score on a display device; and a storage device for storing the allocation data by the calculator, and a score plate A storage device for storing high-resolution font data of various symbols used in a musical score having sufficient resolution as
This high resolution font data is converted into low resolution font data having a resolution sufficient for display on a display device so that the arithmetic processing unit can display on the display device using this low resolution font data. , Which has a sufficient resolution as a composition of a musical score based on the first converter for giving the low resolution font data to the arithmetic processing device, the allocation data given from the arithmetic processing device and the high resolution font data in the storage device. A second computer having a second converter for outputting the musical score data, and a computer typesetting machine for outputting the score block based on the musical score surface data given from the second converter are provided. is there.

(Operation) In the musical composition block making apparatus according to the present invention, the first computer can efficiently allocate the musical score surface on the display screen. Further, the allocated musical score surface can be output as high-resolution musical score data by the second computer. Finally, a computer-generated typesetting machine is used to create a score block based on the score surface data. Therefore, it becomes possible to easily create a clear score reversal.

(Example) Hereinafter, the present invention will be described in detail based on illustrated examples. First
FIG. 1 is a block diagram of a score block creating apparatus according to an embodiment of the present invention. This device comprises a first computer 10, a second computer 20, and a computer typesetting machine 30.

The first computer 10 includes an arithmetic processing unit 11 and a storage unit 1.
2, having a display device 13 and an input device 14.
A commercially available personal computer may be used as the arithmetic processing unit 11 and the storage unit 12. In this embodiment, a PC98XA system manufactured by NEC Corporation is used as the arithmetic processing device 11, and a RAM, a floppy disk device,
A fixed disk device is used as the storage device 12. A high-definition display is used as the display device 13, a mouse is used as the input device 14, and a PC98XA is used.
Used by connecting to the system.

On the other hand, the second computer 20 includes the first converter 21 and the second converter 21.
Converter 22 and storage device 23. In this embodiment, a FACOM-M series general-purpose computer manufactured by Fujitsu Limited is used as the second computer 20, and the first converter 21 and the second converter 22 are actually included in this general-purpose computer. It is realized by software.

In this embodiment, the computer typesetting machine 30 is manufactured by Hell in Germany.
Second computer using Digiset computer typesetting machine 2
The score block can be output based on the score plane data given from 0.

The detailed functions of each component will be described below while explaining the operation of the system shown in FIG. The computer typesetting machine 30 has a function of outputting a score surface having a sufficient resolution as a block copy, and the computer 20 has a high-level output to make the computer typesetting machine 30 output such a high-resolution block copy. The musical score data of the resolution must be supplied. For this reason, the storage device 23 stores high-resolution font data of various symbols (for example, notes, symbols, clefs, etc.) used in musical scores. This high resolution font data has a sufficient resolution as a composition of a musical score. In the storage device 23, in addition to this font data, various constant data necessary for allocating score surfaces (for example, note allocation, note heads, stems, tails, dots, accidental symbols, etc. Data regarding the target position) is also stored.

When the operator actually performs the score assignment work, the computer 10 is not the operation target, but the computer 10.
Is. As described above, since the computer 10 is a personal computer, the operator can give a one-to-one interactive instruction to the computer, which is extremely easy to operate. However, this personal computer cannot handle high resolution font data due to the restrictions of the functions of the arithmetic processing unit 11 and the storage unit 12. Therefore, this high resolution font data
Converted to low resolution font data by the converter 21 of
It will be given to the computer 10. The converted low resolution font data may have a resolution sufficient for display by the display device 13. This conversion is performed by thinning out a two-dimensional matrix of pixels forming the high resolution font data at predetermined intervals, and a font having a size corresponding to an arbitrary staff width can be created on the display. The converted low resolution font data is stored in the storage device 12 via the arithmetic processing device 11. It should be noted that, along with the transfer of the font data, various constant data necessary for allocating the score surface are also transferred. This transfer may be performed by connecting both computers 10 and 20 online, but in the apparatus according to the present embodiment, data is exchanged between both computers using a floppy disk as a medium. Generally, the font data and the constant data are different for each customer who orders the printing of musical scores, so it is convenient to prepare a dedicated floppy disk for each customer.

The operator allocates score surfaces on the display device 13 while performing necessary inputs using the input device 14. This specific allocation method will be described in detail later. On the display device 13, the score surface is displayed using the low resolution font data in the storage device 12. Therefore, the display speed is relatively high, and the work can be performed interactively, so that the allocation with good operability is possible.

Although not shown in the block diagram of FIG. 1, if a printer is connected to the arithmetic processing unit 11, the display unit 13
You can get a hard copy of the score you assigned above. However, since this hard copy uses low resolution font data, it has a very low resolution, and although it can be used for checking data, it is unsuitable for use as a block copy for printing.

Therefore, the actual block copy is output from the computer typesetting machine as follows. First, from the processing unit 11 to the second converter 22
To, allocation data is given, and this allocation data is data including staffs, notes, codes indicating various other symbols allocated on the display device 13, and coordinate values indicating these allocation positions. . The second converter 22 generates score surface data to be given to the computer typesetting machine 30 based on the allocation data and the high resolution font data in the storage device 23, and outputs it. Since this musical score surface data is generated using high resolution font data, the musical score surface data has sufficient resolution as a block for printing. In this way, the musical composition copy is finally output from the computer typesetting machine 30.

Next, an example of the allocation method performed by the operator using the computer 10 will be described based on the flowchart shown in FIG. First, in step S1, the initial menu is displayed on the display device 13. As described above, in the device according to the present embodiment, since the mouse is used as the input device 14, all input is performed by aligning the cursor with the desired command in the menu on the display device 13 with this mouse. It will be. Here, select score creation page (step S2), file management (step S3),
One of the output process (step S4) and the end command is selected.

When the music score page selection command in step S2 is selected, one of four commands is further selected. The new file creation command in step S5 is used when creating an entirely new musical score surface, and performs the work of creating a new musical score file for the musical score surface to be created. The page addition command in step S6 adds the page of the score surface to be created next to the arbitrary page of the score file created in the past. The page correction command in step S7 replaces the specified page of the score file created in the past with the page of the score surface to be created. Further, if the previous step command of step S8 is selected, the process proceeds to step S9 and the process can return to the previous step.

When the processing relating to the page ends in steps S5 to S7,
A work selection is made in step S10 and one of the various work commands described below is selected.

First, in the layout creation command in step S11, staff assignment, bar line assignment, and column setting are performed. FIG. 3 shows a display device when performing such allocation.
13 shows an example of the above display. In the allocation area 41, the score surface for one page to be allocated is displayed. The allocation work is performed by designating each command in the menu area 42. In the upper display area 43 at the upper part of the screen, information such as the file name of the score file currently being created, the number of pages to be allocated, and the size of the page is displayed. In the lower display area 44 at the bottom of the screen,
The coordinate value of a predetermined position in the allocation area 41, for example, the coordinate value of the cursor 45 is displayed. For example, to assign a staff, move the cursor 45 with the mouse into the menu area 42, specify the width and length of the staff, and then move the cursor 45.
Is moved to a desired position in the allocation area 41, and the allocation position may be designated. This device has a function of displaying an auxiliary line that serves as an allocation position index. That is, when a predetermined command in the menu area 42 is specified, the auxiliary line 46 is placed at the leftmost position of the staff.
Is displayed. The operator can use the auxiliary line as an index to perform staff assignment below. It is also possible to provide a command for automatically allocating the lower staff at a position aligned with the upper staff. Similarly, bar lines can be assigned and columns can be designated. In this way 1
The layout of the staff of the page is completed, and the layout creation in step S11 is completed. After this, step S10 is repeated again.

Next, in the musical score data creation command of step S12, notes, rests, clef, key signature, time signature, other ties,
Various special symbols such as slurs are assigned. FIG. 4 shows an example of the display on the display device 13 when such allocation is performed. The difference from the display in FIG. 3 is that the allocation area 47 is enlarged. In this allocation area 47, the entire one page is not displayed, but only a part thereof is enlarged and displayed. In this device, the size when enlarged and displayed is adjusted to be the same size as the score just printed. Therefore, the operator can work while looking at the full-scale display. Allocation of notes, rests, clef, etc. is performed by designation of each command in the menu area 42 and position designation in the allocation area 47 by the cursor 45, as in the above-mentioned staff assignment. Since only a part of one page is displayed in the allocation area 47 as described above, the score surface can be scrolled in the allocation area 47. Also, the menu area 42 is the allocation area 47.
Since it overlaps with this, there is a disadvantage that the assignment work to this overlapping area becomes impossible, but the operator instructs the menu move command in the menu area 42 to move the menu area 42 to an arbitrary position. It is considered to be possible.

When one page has been allocated as described above, step
It is sufficient to specify the page registration command of S13. Based on the selection made in step S2, the currently created page is registered in the predetermined page of the predetermined file. If the page currently created is to be canceled, the page cancel command in step S14 is specified, and this page is not registered. In either case, the work continues again from step S2.

The other page diversion command in step S15 is a command for calling up another already registered page on the screen. This is convenient when you want to change a part of a page created in the past and reuse it. If the previous step command of step S16 is selected, the process proceeds to step S17, and the previous step can be returned.

As described above, the creation of the score surface over several pages is completed. These allocation data are managed as one music score file. The file management in step S3 is for managing such copying and erasing of score files.

Now, when the creation of the score file is completed, the output process of step S4 is performed. As a result, as described above, the allocation data to be given to the second converter 22 is output from the arithmetic processing unit 11.

The present invention has been described above with reference to one embodiment. The feature of the present invention is, in short, that two computers are used, one computer uses a low-resolution font to perform operability allocation, and the other allocation data is allocated to the other computer. It is handed over to the computer of, and the musical score plane data using a high resolution font is created so that a clear musical composition can be output by a computer typesetting machine.

Therefore, the present invention is not limited to the above-described embodiments, and various allocation methods can be adopted in particular.

〔The invention's effect〕

As described above, according to the present invention, in the musical composition block making apparatus, two computers are used, and one computer uses a low-resolution font to perform allocating with good operability, and the allocating data is allocated to the other computer. Since the score plane data using a high-resolution font is handed over and the score copy is output from the computer typesetting machine based on this, it is possible to easily create a clear score copy.
