  An object of the present invention is to provide an electronic information processing apparatus that facilitates identification of folders and files on a display device.

  According to one aspect of the present invention, an electronic information processing apparatus manages storage for storing and storing folders and data files each having a name in a hierarchical structure, and selecting an arbitrary hierarchy from the hierarchical structure Means, detecting means for detecting the folder and data file of the selected hierarchy, giving means for giving a predetermined symbol character to the head of at least one name of the detected folder and data file, and the giving means And a display means for displaying a list of folders and data files to which a predetermined symbol character is added at the head of at least one of the names.

  ADVANTAGE OF THE INVENTION According to this invention, in an electronic information processing apparatus, the folder and file identification on a display apparatus can be made easy.

  FIG. 1 is a block diagram showing a hardware configuration of an electronic music apparatus 1 as an electronic information processing apparatus according to an embodiment of the present invention.

  The electronic music device 1 is a device capable of performing processing related to music, such as an electronic musical instrument having a performance operator such as a keyboard, a sound source device, a mixer device, and an audio recording or reproducing device.

  A RAM 7, ROM 8, CPU 9, timer 10, detection circuit 11, display circuit 13, storage device 15, sound source / effect circuit 18, and communication interface (I / F) 21 are connected to the bus 6 of the electronic music apparatus 1.

  The RAM 7 has a buffer area such as a reproduction buffer, a working area of the CPU 9 that stores flags, registers, various parameters, and the like.

  The ROM 8 can store various data files, various parameters and a control program, or a program for realizing the present embodiment. In this case, it is not necessary to store programs or the like in the storage device 15 in an overlapping manner.

  The CPU 9 performs calculation or control of the electronic music apparatus 1 according to a control program stored in the ROM 8 or the storage device 15 or a program for realizing the present embodiment. The timer 10 is connected to the CPU 9 and supplies a basic clock signal, interrupt processing timing, and the like to the CPU 9.

  The user can perform various inputs, settings, and selections using the setting operator 12 connected to the detection circuit 11. For example, the setting operator 12 may be any switch, pad, fader, slider, rotary encoder, joystick, jog shuttle, character input keyboard, mouse, or the like that can output a signal in accordance with the user input. . The setting operator 12 may be a soft switch or the like displayed on the display device 14 that is operated using another operator such as a cursor switch. In this embodiment, the user uses the setting operator 12 to select a folder (directory or hierarchy) whose contents are displayed as a list on the display device 14 or a data file included in the hierarchy.

  The display circuit 13 is connected to the display device 14 and can display various information on the display device 14. The user refers to the information displayed on the display device 14 and performs various inputs and settings. In this embodiment, as will be described later, a plurality of folders (or directories) DR and a plurality of data files DF stored in the storage device 15 or the ROM 8 are displayed as a list on the display device 14. In the present embodiment, the display device 14 may be capable of displaying at least text information.

  The storage device 15 is a combination of a storage medium such as a hard disk, an FD (flexible disk or floppy disk (registered trademark)), a CD (compact disk), a DVD (digital multipurpose disk), or a semiconductor memory such as a flash memory, and a driving device thereof. It is composed of at least one. The storage medium may be detachable or may be built in the electronic music apparatus 1. The storage device 15 and / or the ROM 8 can store a program for realizing each embodiment of the present invention and a program for controlling the other electronic music device 1. In the case where a program for realizing each embodiment of the present invention and other programs for controlling the electronic music apparatus 1 are stored in the storage device 15, it is not necessary to store them together with the ROM 8. Alternatively, only some programs may be stored in the storage device 15 and other programs may be stored in the ROM 8.

  In the storage device 15 and / or ROM 8, for example, as shown in FIG. 2, a plurality of folders (or directories) DR and a plurality of data files (song data, accompaniment style data, DF (tone color data, various setting files, etc.) is managed and stored in a hierarchical structure. Specifically, a plurality of folders DR (for example, “USER”, “AAA”, “BBB”, etc.) are stored under the folder (directory) DR (for example, “ROOT”). A plurality of folders DR (for example, “SONG”, “CCC”, etc.) are also stored below each of them, and a data file DF (for example, “DDD”) is also stored. In a folder DR (folder “ROOT> USER> SONG”) displayed in a list display example (FIG. 3) to be described later, for example, a folder “USER SONG” and a data file (music data file) “USER SONG”, “ “SONG 001” and “SONG 002” are stored.

  Returning to FIG. 1, the sound source / effect circuit 18 is a music data file DF recorded in the storage device 15, ROM 8, RAM 7, or the like, a performance operator 22, or a performance signal supplied from an external device connected to the communication interface 21. A musical tone signal is generated in accordance with the MIDI signal and the like, and various musical effects are given to the sound system 19. The sound system 19 includes a D / A converter and a speaker, converts a digital musical tone signal supplied to an analog format and generates a sound.

  A performance operator (keyboard, pad, etc.) 22 is an operator for inputting a user's performance, and has a pitch corresponding to the operator operated by the user and an operation start timing and an end timing for the user's operator. Are input as key-on and key-off signals, respectively.

  The communication interface 21 is a music-only wired I / F such as MIDI, a general-purpose short-distance wired I / F such as USB or IEEE1394, a general-purpose network I / F such as Ethernet (registered trademark), a wireless LAN, Bluetooth (registered trademark), or the like. And at least one communication interface such as a general-purpose short-range wireless I / F.

  FIG. 3 is a list display example of the folder DR and the file DF according to the embodiment of the present invention.

  This list display is displayed on the display device 14 of FIG. 1 using text data. In this example, the hierarchy of “ROOT> USER> SONG” in the directory structure shown in FIG. 2 is selected by the user's operation of the setting operator 12. In this folder DR (“SONG”), a “USER SONG” folder DR and a “USER SONG” file DF having the same name are stored. In addition, file DFs named “SONG 001” and “SONG 002” are stored.

  In this embodiment, by adding a symbol character to the head part of the file name, a step is created between the folder name and the file name so that the folder DR and the file DF can be recognized at a glance.

  Specifically, as shown in the figure, most of the display area for one character such as “_” is given a blank symbol character, and the file name to which this is given and the folder that is not given The name is displayed as if there is a step, making it easy to distinguish between the two.

  FIG. 4 is a flowchart showing the folder / file list display process according to the embodiment of the present invention. In this process, when it is necessary to browse the folder DR and the file DF stored in the storage device 15 of the electronic music apparatus 1, or the folder DR and the file DF stored in the storage device 15 are managed ( This is activated when selecting for copying, renaming, deleting, etc.), editing, reproduction, etc.

  In step SA1, a folder / file list display process is started. In step SA2, selection of a display target folder (hierarchy) DR is accepted. The folder DR is selected by the user using the setting operator 12 in FIG. 1 to select a desired folder DR from among a plurality of folders DR managed and stored in the storage device 15 in FIG. At this time, the root directory (“ROOT” in the example of FIG. 2) of the storage device 15 may be automatically selected as the initial screen, and the contents of the root directory are displayed by the processing of the following steps SA3 to SA5. A desired folder DR may be selected from among them. Further, the user may select a desired folder DR name by directly inputting it using the setting operator 12 or the like. Further, information (path and the like) related to the folder DR selected by the previous folder / file list display process is stored in the storage device 15 or a temporary storage area in the RAM 7 so that the stored folder DR is automatically selected. Anyway.

  In step SA3, the folder DR and the data file DF included in the folder DR selected in step SA2 are detected from the storage device 15. Here, text data representing the names of the detected folder DR and data file DF is extracted and temporarily stored in, for example, a buffer area in the RAM 7.

  In step SA4, a predetermined symbol character is added to the head of the file name of the data file DF detected in step SA3. That is, predetermined text data (symbol characters) is added to the head of the text data representing the name of the data file DF temporarily stored in the buffer area in the RAM 7 in step SA3 and temporarily stored in the buffer area in the RAM 7. Update the name of the data file DF. This predetermined symbol character is only temporarily given for list display and does not affect the original name.

  Any symbol character may be added in step SA4, but for example, most of the display area for one character such as “_” or “￣” is preferably blank. . Moreover, you may give a space (blank) as a symbol character. By adding a blank symbol character or a space (blank) to the majority of the display area for one character, a display appears as if there is a step between the file name to which it is added and the folder name that is not assigned. Both can be identified more easily.

  In step SA5, the names of the folder DR and the data file DF detected in step SA3 are rearranged in a predetermined sort order and displayed on the display device 14. Specifically, the text data representing the name of the folder DR extracted in step SA3 and temporarily stored in the buffer area in the RAM 7 and the text data extracted in step SA3 and temporarily stored in the buffer area in the RAM 7 are stored in step SA4. The text data representing the name of the data file DF with a symbol character at the head is sorted in a predetermined sort order and displayed on the display device 14. Here, the predetermined sort order includes ascending order of names, descending order, file size order, file type order, file creation / update date order, and the like. Thereafter, the process proceeds to step SA6, and the folder / file list display process is terminated.

  In step SA4, a symbol character is added to the head of the data file name. However, a symbol character may be added to the head of the folder name. Different symbol characters may be assigned to both the folder name and the file name.

  It is preferable that the same symbol character as the predetermined symbol character added to the head of the folder (directory) name or data file name cannot be added in advance to the folder (directory) name or data file name. This is because if the same symbol character is assigned in advance, it cannot be determined whether or not it is automatically assigned. Alternatively, the same symbol character may be given at the middle or end other than the beginning of the folder (directory) name or data file name.

  Further, when folders (directories) are displayed in multiple stages in the list display, a plurality of predetermined symbol characters may be added to indicate the multistage.

  As described above, according to the embodiments of the present invention, the folder name and / or file name is given a symbol character at the beginning and the folder name and file name are displayed in a list on the display device. Identification becomes easy.

  Moreover, since the symbol character is added, the folder and the file can be easily identified even on a display device capable of displaying only the character information (text data).

  In addition, by adding a blank symbol character or a space (blank) in most of the display area for one character, there is a difference between the file name to which this is given and the folder name that is not given. It becomes a display and it becomes easier to identify both.

  Although the present invention has been described with reference to the embodiments, the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications, improvements, combinations, and the like can be made.
