DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to an electronic apparatus used for managing files recorded on a recording medium such as a floppy disk, a hard disk, a magneto-optical disk, and the like.

[0002]

2. Description of the Related Art Conventionally, a plurality of files are saved on one recording medium in units of a set of data called a file. In this case, the file name is arbitrarily given by the user, and each file is usually identified by the file name.

[0003]

By the way, in the above-mentioned conventional electronic devices , a file is identified by a file name, so that files having the same contents are separately saved on one recording medium if the file name is different. For this reason,
In some cases, a plurality of files having the same content exist in one recording medium. In such a case, the storage area of the recording medium is wasted and the processing time for saving the file to the recording medium is wasted. A problem arose.

Further, a file is stored in a RAM (Random Access
In the case of loading to a memory such as a memory, if a plurality of files having the same content exist in one recording medium, a plurality of files having the same content may be loaded together. In such a case, there is a problem that the memory area is wasted and the processing time for loading the file into the memory is wasted.

[0005] Further, since the identity of the file name cannot be managed in different recording media, files having the same file name with different contents may be saved. Here, if the files having the same file name cannot be loaded at the same time, there is a problem that only one file can be loaded among a plurality of files having different contents.

The present invention has been made in view of the above-mentioned circumstances, and can eliminate unnecessary processing when loading or saving a file on an external recording medium, and efficiently use a recording medium or a memory such as a RAM. It is an object of the present invention to provide an electronic device capable of preventing a plurality of files having the same contents from being saved or loaded, and capable of distinguishing between files having the same file name with different contents.

[0007]

In order to solve the above-mentioned problems, the invention according to claim 1 enables a file stored in a recording medium to be loaded into an internal storage means, and a file stored in the internal storage means. In an electronic device that enables a stored file to be saved on the recording medium, the saving unit assigns a file name and an identification number to the file during the saving, wherein the file to be saved is newly created. If the file is to be saved, or if the file to be saved is an edited file, a new identification number is automatically added to the file, and the file is loaded at the time of loading. It is determined whether or not a file having the same identification number as the file identification number is stored in the internal storage means, and is stored. It is characterized in that a load control means for controlling so as not to load the file. According to a second aspect of the present invention, in the electronic device according to the first aspect, the load control unit determines whether or not a file having the same file name as a file to be loaded is stored in the internal storage unit. Is determined, and if the file is stored, the user is notified that the file name of the file to be loaded should be changed. According to a third aspect of the present invention, there is provided an electronic apparatus according to the first or second aspect.
Oite, during pre-Symbol saving and a file with the same identification number as the identification number of the file to be saved, it is determined whether or not stored on the recording medium, are stored, save the file and further comprising a save control means to control so as not to.

[0008]

According to the present invention, a plurality of files having the same contents are saved because different identification numbers are generated inside the device and are automatically assigned to a plurality of files recorded on a recording medium. In addition, loading can be prevented, and files having the same file name with different contents can be distinguished. Thus, unnecessary processing when loading or saving a file on the external recording medium can be eliminated, and a recording medium or a memory such as a RAM can be used efficiently.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an electronic musical instrument to which the present invention is applied. In FIG. 1, reference numeral 1 denotes an external memory such as a floppy disk, hard disk, or magneto-optical disk. The external memory 1 stores wave data and voice data files as shown in FIGS. These files have different identification numbers for each file (however, the same identification numbers are assigned to files having the same contents), and files such as whether the data is wave data or voice data. A type name for identifying the type and a file name written by the user are recorded. Further, in the wave data file, environmental data relating to a sampling frequency, a sound range, and the like, and waveform data based on PCM data are recorded. On the other hand, in the voice data file, in addition to the identification number, the type name, and the file name described above, various parameters such as pitch and volume, the identification number of the wave data file serving as combination data, and the file name are included. It is stored as timbre data.

As an example, FIG. 4 shows a floppy disk A,
B shows the data content of the file recorded in B. The floppy disk A has files to which identification numbers (here, for simplicity, 100, 200, 300, and 400, respectively) are assigned. Voice, Wave, Wave, and Voice are given to these files as type names, respectively, and analog synth, triangular wave, sawtooth wave, and synth brass are respectively given as file names. Further, in the file with the identification number 100, the identification number of the file serving as the combination data and the file name are stored as “200 triangular wave + 300 sawtooth wave”, and in addition, various parameters are stored. Similarly, the file with the identification number 400 includes “30
“0 sawtooth wave + 300 sawtooth wave” and various parameters are stored. The combination data of the file with the identification number 400 is two wave data (“300
"Sawtooth wave + 300 sawtooth wave") is stored. This is because two sets of the same data are used to thicken the sound by performing different processing on the two sets of wave data to slightly shift the pitch (detune). Is stored.

On the other hand, the floppy disk B has a file with an identification number 500. Identification number 50
The file 0 is assigned voice and synth brass as a type name and a file name, respectively, and further stores an identification number of the file serving as combination data and its file name, such as “300 sawtooth wave”. In addition, various parameters are stored.

In FIG. 1, reference numeral 2 denotes a RAM (Random Acceses).
s Memory), which has a work area for the CPU (central processing unit) 3 and a storage area for temporarily storing files from the external memory 1 described above. Further, 4 is a ROM in which a control program is stored, 5 is a panel switch such as a keyboard, 6 is a display circuit for performing various displays to the user, and 7 is a tone generator circuit for generating musical sounds. CPU
Reference numeral 3 denotes an external memory 1, a RAM 2,
ROM 4, panel switch 5, display circuit 6, tone generator circuit 7
Control.

Next, a processing procedure in which the CPU 3 loads a file in the external memory 1 into the RAM 2 will be described with reference to FIG. First, when loading of a file is started by the CPU 3, the process proceeds to step S1, and a file to be loaded is designated by the user. At this time, the specified file is specified by an identification number (ID) and a file name. Next, the process proceeds to step S2, where the file having the same identification number as the designated file is
It is determined whether it exists in M2. This judgment is "Ye
s ", the process proceeds to step S3, and the display circuit 6 displays" the specified file already exists. "
A series of processing ends. That is, the fact that the identification data is the same means that the contents of the file are also the same, so that it is not necessary to newly load the file.

If the determination in step S2 is "No", the flow advances to step S4 to determine whether or not a file having the same file name as the file specified in step S1 exists. If the determination is “Yes”, the process proceeds to step S
The process proceeds to step S5, where the user changes the file name, and proceeds to step S6. Further, the determination in step S4 is “No”
If so, the processing in step S6 is skipped without performing the processing in step S5.
Proceed to. In step S6, the designated file is stored in RAM
2 and then proceed to step S7. Step S
At 7, it is determined whether or not the type name of the loaded file is voice. If this determination is "No", the flow proceeds to step S8, where "load end" is displayed by the display circuit 6, and a series of processing ends.

If the determination in step S7 is "Yes", the flow advances to step S9 to determine whether there is a file to which the same identification number as that of the wave data file used in the voice data file exists. Judge. If this determination is “Yes”, the process proceeds to step S8, and if “No”, the process proceeds to step S10. In step S10, the wave data file to be used is
Load to M2.

In step S10, if the external memory 1 to be used is removable such as a floppy disk, a file of wave data to be used may exist on another floppy disk. In such a case, the currently inserted floppy disk is ejected, and the display circuit 6 indicates that another floppy disk is to be inserted. Then, when another floppy disk is inserted, a file of wave data is searched. Such a process is repeated until a floppy disk containing a desired file is inserted. When this file is searched, the file is loaded into the RAM 2, the processing in step S8 is performed, and a series of processing ends.

Next, a processing procedure in which the CPU 3 saves a file in the RAM 2 will be described with reference to FIG. In this example, all desired files on the RAM 2 are automatically and sequentially saved. First, CP
When the saving of the file is started by U3, the process proceeds to step S110, and any one of the files to be saved is automatically designated. At this time, if the specified file is a newly created file or an edited (edited) file, a new file name is given by the user, and the process proceeds to step S111. In step S111, it is determined whether the specified file is newly created or edited. If this determination is "Yes", the flow proceeds to step S112.
A 32-bit random number is generated, and the process proceeds to step S113. In step S113, the random number is written to the RAM 2 as the identification number of the specified file. Since a new identification number is assigned only to a newly created file or an edited file in this way, it can be said that files having different identification numbers always have different file contents. In addition,
When the file is copied for some reason, the contents are the same, so that the identification data is also stored. Next, the process proceeds to step S114, and it is determined whether or not the same file name as the specified file name exists in the external memory 1. If this determination is "Yes", the process proceeds to step S11.
The program proceeds to step 5, where the user is prompted to select either to change the file name or to delete the file having the same file name from the external memory 1, and execute it. When changing the file name, wait until the user changes the file name.
Next, when the process proceeds to step S116, the designated file is saved in the external memory 1, and the process proceeds to step S117.
In step S117, it is determined whether or not all desired files on the RAM 2 have been saved. This judgment is "N
If "o", the process returns to step S110, and "Yes"
If so, the process proceeds to step S118. In step S118, "save completed" is displayed on the display circuit 6, and a series of processing ends.

If the determination in step S111 is "No"
In the case of, the process proceeds to step S119, and it is determined whether or not the same identification number as the identification number of the specified file exists in the external memory 1. If this determination is “No”, the processing after step S114 is performed, and if “Yes”, the file does not need to be saved, so that step S114 is performed.
The processing after 117 is performed.

The random number generated in step S112 rarely generates the same value as long as it is about 32 bits, but an algorithm random number having a long cycle until the same random number appears is preferable.

Next, the procedure for loading the files on the floppy disks A and B into the RAM 2 will be described with reference to FIG.
First, in step S1, the file "100
When "analog synth" is designated, the process proceeds to step S2.
Since there is no file with the same identification number as the identification number “100” of this file in the RAM 2,
The determination in step S2 is "No", and the process proceeds to step S4. In step S4, a file having the same file name as the file name "analog synth"
Since it does not exist in M2, the result is "No" and step S6
Proceed to. In step S6, the file "100 analog synth" is loaded, and the process proceeds to step S7. Since the loaded file “100 analog synth” is voice data, the process proceeds to step S9. Then, the combination data of this file is “200 triangular wave” and “3
Since it is “00 sawtooth wave”, it is determined whether or not a file having the same identification number as the identification number of these two files exists in the RAM 2. The determination in step S9 is "N
o ", and the files" 200 triangular wave "and" 300 sawtooth wave "are loaded into the RAM 2 in step S10. Next, the process proceeds to step S8, where "load completed" is displayed, and a series of processing ends.

Next, the process proceeds to step S1 again, and when the file "400 synth brass" is designated, similarly to the file "100 analog synth" described above, steps S2 and S2 are performed.
Processes 4, 6, 7, and 9 are sequentially performed. In step S9, the combination data of this file is stored in the file “30”.
Since it is “0 sawtooth wave”, it is determined whether or not a file having the same identification number as that of this file exists in the RAM 2. The determination in step S9 is "Yes", and the process proceeds to step S8. In step S8, "load completed" is displayed, and a series of processing ends.

Next, the external memory 1 is stored in the floppy disk A
And replace it with floppy disk B. Then, the process proceeds to step S1, and when the file "500 synth brass" is designated, the processes of steps S2 and S4 are sequentially performed similarly to the above-mentioned file "400 synth brass". In step S4, since the file "400 synth brass" having the same file name exists in the RAM 2, the determination here is "Yes" and the process proceeds to step S5. Step S5
In, one of the file names of the files “400 synth brass” and “500 synth brass” is changed. In this case, the file name of the identification number “500” is changed to, for example, “Synth Brass 1”. The following processing is performed for the file "4
00, synth brass ", steps S6, 7, 9, 8
Then, “load completed” is displayed, and a series of processing ends.

The method of assigning a random number to a file as an identification number according to the present invention has the advantage that a common floppy can be used between an unspecified number of devices because it is not necessary to manage the assigned identification number. The number of devices to be used may be limited to one or a plurality of specific devices, the identification numbers already used may be recorded, and the newly assigned identification numbers may be other than the recorded identification numbers. If a limited number of devices are used, identification numbers can be assigned without using random numbers. In this case, the use range is limited, but the file is managed more reliably than when a random number is used. In this case, the newly assigned identification number may be the identification number of the deleted file. Further, the identification number of the file is given when the file is saved on the external recording medium, but may be given when the file is created or when the file is changed. Further, the voice data and the wave data are separated, and the combination data of the wave data is provided as the voice data. However, the wave data may be dependent on the voice data to have the data. Further, the present invention is applied to an electronic musical instrument, but the present invention is not limited to this, and may be applied to other devices.

[0024]

As described above, according to the present invention, different identification numbers are assigned to a plurality of files recorded on a recording medium, so that a plurality of files having the same contents are saved. And loading can be prevented, and files having the same file name with different contents can be distinguished. Thus, unnecessary processing when loading or saving a file on the external recording medium can be eliminated, and a recording medium or a memory such as a RAM can be used efficiently.
