In recent years, portable data playback devices such as compact disc players and portable audio players with built-in hard disks are often used particularly outdoors, and the size has been further reduced.
In addition, a storage medium such as a hard disk in which data is stored has been increasing in data area that can be stored.
With the increase in the data area that can be stored in the storage medium, the number of data stored in the storage medium is increased, and various types of data such as music data and video data can be stored.
That is, recent portable data reproducing apparatuses have been reduced in size, and the storage area in which data can be stored has increased, so that users can carry and enjoy a wide variety of data.

  However, it has become very complicated to search for a desired music piece as the capacity of the storage medium increases. Conventionally, in order to select music, the music is displayed in a list and scrolled to select a desired music. However, as the storage medium increases in capacity, the number of music becomes enormous and scrolls. It takes a very long time.

In order to solve such a problem, an operation mode control device capable of measuring the pressing time of the operation button arranged at the operation part and determining whether or not the measured time exceeds an arbitrary fixed time. Etc. are disclosed (for example, refer to Patent Document 1).

  According to the present invention, it is possible to improve the operability related to search.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing an example of a sound reproduction device applied to the embodiment of the present invention. This sound reproduction device is a device that can display a list of data (for example, music data such as MP3 (MPEG1 Audio Layer-3)) stored in the storage unit 11 on the display unit 12, and includes a control unit 10 and a storage unit 11, a display unit 12, an operation unit 13, and an audio output terminal 103.

  The operation unit 13 includes a predetermined button switch, a rotary switch, and the like, and inputs instruction information according to a user operation. For example, the operation unit 13 includes an up key 17, a down key 18, a left key 19, a center key 20, and a right key 21. Here, the up key 17 and the down key 18 are double tact keys that can be physically pressed in two stages. The first-step pressing and the second-step pressing of the double tact key generate separate analog signals using a resistance voltage dividing circuit connected to the tact key.

The configuration of the resistance voltage dividing circuit connected to the double tact key will be described with reference to FIG. The resistance voltage dividing circuit includes a resistor R1, a resistor R2, a resistor R3, a resistor R4, a switch S1, and a switch S2. The switch S1 is turned on by pressing the first step of the double tact key (hereinafter referred to as weak pressing), and the switch S2 is turned on by pressing the second step of the double tact key (hereinafter referred to as strong pressing). Called push).
When the tact key is not pressed, the output voltage Vout is (R2 / (R1 + R2)) × power supply voltage Vcc. The upper key 17 and the lower key 18 include resistors R2, R3, and R4 having different resistance values. By pressing the first stage of the double tact key, the output voltage Vout becomes ((R2 // R3)) / (R1 + (R2 // R3))) × power supply voltage Vcc. Further, the output voltage Vout is configured to be ((R2 // (R3 + R4)) / (R1 + R2 // (R3 + R4))) × power supply voltage Vcc by pressing the second stage of the double tact key. Thereby, the resistance voltage dividing circuit can supply the output voltage Vout to the control unit 10 which is different depending on whether the tact key is pressed at the first stage or the second stage.

  The configuration of the resistance voltage divider connected to the left key 19, the center key 20, and the right key 21 will be described with reference to FIG. The resistance voltage dividing circuit includes a resistor R1, a resistor R5, a resistor R6, and a switch S3. The difference from the double tact key is that only one switch and a resistor connected to the ground and connected in series are attached one by one and can be physically pressed only in one stage. Similarly, the left key 19, the center key 20, and the right key 21 are provided with resistors R5 and R6 having different resistance values.

  2 and 3, each key of the operation unit 13 (upper key 17 is pressed and pressed down, down key 18 is pressed down and pressed down, left key 19, center key 20 and right key are pressed. The operation of key 21) produces a different output voltage Vout. The output voltage Vout is output from the operation unit 13 and input to the A / D converter 14.

  Returning to FIG. 1, the control unit 10 includes, for example, a CPU 100 (Central Processing Unit), an interrupt controller 101, an A / D converter 14, a RAM 104 (Random Access Memory), and the like. By appropriately executing the key code processing application 15a and the key processing driver 15b), the operation of the entire sound reproduction device is controlled. In addition, the CPU 100 has an internal timer. Further, as described above, at least the key code processing application 15a and the key processing driver 15b are stored. The key code processing application 15a and the key processing driver 15b may be configured as software or hardware. The A / D converter 14 converts the analog signal supplied from the operation unit 13 into a digital signal and outputs the digital signal. The RAM 104 is used as a work memory for loading reproduction data or the like when the CPU executes a program.

The key processing driver 15b performs a bridge for the CPU 100 to supply a key code to the key code processing application 15a. Specifically, the instruction information (analog signal) input from the user via the operation unit 13 is generated from the digital signal once input through the A / D converter 14 and supplied to the CPU 100. Further, by using the timer of the CPU 100, the pressing time of the key corresponding to the key code is also determined and supplied to the CPU 100. The key code processing application 15a is supplied with the key code generated by the key processing driver 15b (and pressing time information if necessary), and determines the processing by key input based on the supplied key code. It supplies to CPU100. As a result, operations corresponding to different operations of the user in the operation unit 13 are executed. Specifically, when the operation unit 13, the A / D converter 14, the key processing driver 15b, the key code processing application 15a, and the CPU 100 cooperate with each other, for example, if the play key is pressed, the playback processing unit is activated. The music data and the like are controlled to be reproduced, and if the scrolling of the list is instructed, the display unit is controlled to scroll the list.
More specifically, the instruction information (analog signal) input from the user via the operation unit 13 is the output voltage Vout distinguished for each tact key as described above. Then, the key processing driver 15b assigns a different digital signal via the A / D converter 14 for each of these different output voltages Vout, and uses this as a key code corresponding to the operation as a key code processing application 15a via the CPU 100. To supply. For example, a key code “010” may be supplied when the user presses the upper key 17, and a key code “011” may be supplied when the right key 21 is pressed by the user.

  The key code processing application 15a executes processing corresponding to the key code supplied from the key processing driver 15b. For example, the key code processing application 15a causes the display unit 12 shown in FIG. 1 to display the scroll status of the highlight 30 on the GUI 12a as shown in FIG. At this time, the key code processing application 15a displays a folder / file name and highlight at an appropriate position on the GUI according to the key code and a table for managing a data folder to be described later. Here, the processing corresponding to the key code is stored in advance as a table in the storage unit 11 or another ROM. The key code processing application 15a executes a corresponding process against the table when the key code is supplied.

  The storage unit 11 includes a storage device such as a hard disk. The storage unit 11 stores hierarchical information that defines a file structure such as the data in addition to data such as music data. For example, when the data or the like has a file structure as shown in FIG. 8, hierarchical information that defines these file structures is stored. The hierarchy information includes a folder table 101 as shown in FIG. 5A and a display management table 102 as shown in FIG.

  A folder table 101 shown in FIG. 5A is a folder that stores data stored in the storage unit 11, that is, a folder that can be displayed on the display unit 12 among folders that serve as management units for hierarchical data. It is a table for managing. Specifically, the folder table 101 stores folder / file names and data numbers for identifying a plurality of folders that can be displayed. The folder / file name stored in the folder table 101 is a folder / file name of a plurality of data belonging to the current reference folder (current folder). For example, if the current folder is folder 1 in the file structure as shown in FIG. 8, the folder table 101 stores folder / file names and data numbers of folder 2, folder 4, and folder 9. .

  On the other hand, the display management table 102 shown in FIG. 5B is a table for managing folder / file names to be displayed corresponding to the folder table 101. Specifically, the display management table 102 includes a current folder name that identifies the current reference folder, a hierarchy number that indicates the hierarchy order (hierarchy depth) where the folder in the current folder is located, and the current folder. The display data number for specifying one folder to be displayed in the list and the total number of data indicating the total number of data belonging to the current folder are stored. For example, in the file structure as shown in FIG. 8, if the current folder is folder 1, the hierarchy number is “002” and the total number of data is “003”.

  Returning to FIG. 1, the display unit 12 is composed of a flat panel display such as a fluorescent display tube (VFD) and a liquid crystal display (LCD), and is controlled by the control unit 10 to control the operation status and the like. A character string or the like for making the user clear is displayed. Further, for example, a display area for 8 lines for displaying the contents of the folder table 101 stored in the storage unit 11 is arranged on the display unit 12.

  The reproduction processing unit 112 performs reproduction processing of data (for example, music data such as MP3) stored in the storage unit 11. For example, the MP3 decoder converts MP3 data into a WAVE file, and the D / A converter (sound card) outputs the WAVE file in analog form. The MP3 decoder may be implemented as hardware by mounting on an LSI (Large Scale Integration) chip.

  The analog signal converted by the D / A converter outputs the reproduced sound amplified by the amplifier circuit from the sound output terminal 103 (headphone connection unit) to the outside.

  In the above, each structure in the embodiment of this system was demonstrated.

  Next, a specific operation of this apparatus having the above configuration will be described with reference to FIGS. First, data selection processing for selecting data such as music data stored in the storage unit 11 will be described.

  6 and 7 are flowcharts for explaining the data selection process. The data selection process shown in FIGS. 6 and 7 is started by an interrupt input from the operation unit 13 when the up key 17 or the like shown in FIG. 1 is pressed.

  When the interrupt is input, the control unit 10 is not in the data selection mode, for example, during data reproduction (step S201; No), and the subsequent operation process shifts to another process. At this time, if the data selection mode is a list selection of music, album names, and performers (step S201; Yes), it is determined whether the pressed key is the up key 17 or the down key 18. As described above, this is determined by the key code supplied from the key processing driver 15b.

  Here, if the pressed key is not the up key 17 or the down key 18 (step S202; No), as shown in FIG. 7, it is determined which key is pressed (step S213, step S217). ), In that case, will be described later.

When it is determined that the upper key 17 or the lower key 18 is pressed (step S202; Yes), an internal timer of the CPU is started (initialized) to measure the time during which the key is continuously pressed. (Step S203).
If the key pressed state is maintained after the timer is started, for example, the count is incremented by one every 20 msec (step S205).

  At the same time, an instruction to scroll one highlight on the GUI of the display unit 12 is issued in accordance with the pressed key (up key 17 or down key 18) (step S204). Specifically, if the down key is pressed, “1” is added to the display data number in the display management table 102 of FIG. 3B, and if the up key is pressed, “1” is added to the display data number. Subtract. Details of the highlight scroll process and the display process will be described later.

  Thereafter, it is determined whether or not the count exceeds a specified number (for example, 100 times (2 sec)) (step S206). If the count does not exceed the specified number (step S206; No), it is determined whether or not the pressed key has been released (step S212). At this time, if the key has been released (step S212; Yes), the control unit 10 clears the count (step S213) and ends the process.

  If the key is not released at step S212 (step S212; No), the count is incremented by one again, and the above processing is repeated until the count exceeds the designated number or the key is released. repeat.

  On the other hand, when it is determined in step S206 that the count has been exceeded (step S206; Yes) (when it is determined that the key has been continuously pressed for a predetermined period), the double tact key that can be pressed in two steps is pressed strongly. If it is identified (step S207; Yes), it is instructed to scroll the highlight on the GUI at high speed (step S208). Specifically, for example, “1” may be added to or subtracted from the display data number in the display management table 102 of FIG. 3B every 20 msec. If it is specified that the double tact key is weakly pressed (step S207; No), the highlight on the GUI is instructed to scroll at a low speed (step S210). Specifically, for example, “1” may be added to or subtracted from the display data number in the display management table 102 of FIG. 3B every 200 msec.

The instruction in step S208 or the instruction in step S210 is repeated until it is determined that the up key 17 or the down key 18 is released (step S209; No, step S211; No). At this time, even when the strong press is switched to the weak press according to the user's instruction during the scroll, it is determined whether or not the strong press is made in step S207 (step S207), and the high-speed scroll instruction ( Scrolling can be continued by switching between step S208) and a low-speed scroll instruction (step S210) according to the user's instruction.
When it is determined that the key has been released (step S209; Yes, step S211; Yes), the count is cleared (step S213), and the process ends.

  Returning to step S202, when it is determined that the center key 20 or the right key 21 has been pressed without pressing any key other than the up key 17 or the down key 18 (step S202; No) (step S213; Yes). Then, it is determined whether or not the data of the folder / file name highlighted on the GUI is a folder (step S214). If the data is a folder (step S214; Yes), the data is moved to a folder one level below (step S216). Specifically, the folder data belonging to the highlighted folder is searched, the folder table 101 shown in FIG. 3A is generated according to the search result, and the display management table 102 shown in FIG. The total number of data and the current hierarchy number are also updated, and the process is terminated.

  If it is determined in step S214 that the data is not a folder (step S214; No), the data is selected (step S215), a reproduction program or the like is started, and the data selection process is terminated (step S220). .

  In step S213, if the left key 19 is pressed (step S217; Yes) instead of the center key 20 and the right key 21 (step S213; No), the folder moves to the folder one level higher (step S213; Yes). S218). Specifically, the folder data belonging to the highlighted folder is searched, the folder table 101 shown in FIG. 3A is generated according to the search result, and the display management table 102 shown in FIG. The total number of data and the current hierarchy number are also updated, and the process is terminated.

  When a key that is not one of the upper key 17, the lower key 18, the left key 19, the center key 20, and the right key 21 is pressed (step S217; No), the other key is pressed to perform another process. The process proceeds (step S219).

  That is, if the upper key 17 is continuously pressed for a predetermined time or more, the highlight scrolls upward. At this time, if it is weakly pressed, it scrolls at a low speed, and if it is strongly pressed, it scrolls at a high speed. Similarly, when the down key 18 is kept pressed for a predetermined time or longer, the highlight scrolls downward.

  The above is the description of the operation of the data selection process. Next, a highlight scroll process on the GUI and an operation of the display process will be described.

  The control unit 10 displays the folder / file names in the folder table 101 shown in FIG. 3A on the display unit 12. At this time, the folder / file names in the folder table 101 of the current folder are displayed in FIG. As shown, it is displayed in the display area of the display unit 12a. For example, when the number of items to be displayed simultaneously on the GUI is 8, folders and file names having data numbers “001” to “008” are displayed in order from the top on the GUI. In the following description, the number of items for displaying folder / file names is assumed to be 8. However, it is not necessary to limit to this number.

  The control unit 10 instructs the folder / file name of the data having the data number designated by the display data number in the display management table 102 shown in FIG. 3B to be displayed highlighted on the GUI. . For example, if the display data number is “004”, only the folder / file name having the data number “004” among the data having the data numbers “001” to “008” displayed on the GUI is displayed. Instructs the display to be highlighted. At this time, the display data number may be displayed together with the folder / file name. Further, a hierarchy number indicating the folder hierarchy position (hierarchy depth) may be displayed together with the folder / file name.

  Further, when moving between folders having different hierarchies in step S216 or step S218 in FIG. 7 described above, the control unit 10 displays the display data numbers in the display management table 102 shown in FIG. Is set to “001”. As a result, the highlighted data on the GUI is always the top folder / file name.

  Next, highlight scroll processing on the GUI will be described. As shown in FIG. 2, the scroll in the present embodiment means that one or more highlights on the GUI move between items in order from the top or bottom. Specifically, the control unit 10 subtracts “1” from the display data number in the display management table 102 shown in FIG. 3B (when the upper key 17 is pressed) or adds “1” from the display data number. (When the down key 18 is pressed).

  In addition, when the data currently displayed on the GUI is “001” to “008” and the display data number is “008”, at this time, when “1” is added to the display data number The control unit 10 instructs to switch the data displayed on the GUI from “009” to “016”. Also, when the data currently displayed on the GUI is “009” to “016” and the display data number is “009”, at this time, when “1” is subtracted from the display data number The control unit 10 instructs the data displayed on the GUI to be switched from “001” to “008”.

  Separately, when the data currently displayed on the GUI is “001” to “008” and the display data number is “008”, “1” is set to the display data number at this time. When the addition is performed, the control unit 10 may instruct to switch data displayed on the GUI from “002” to “009”.

  When it is determined that the upper key 17 is pressed while the display data number of the display management table 102 is “001”, the control unit 10 sets the total number of data to the display data number, and the folder table 101. The last folder / file name is displayed on the display unit 12. Further, when it is determined that the down key 18 is pressed while the display data number of the display management table 102 is the last data number (the same value as the total number of data), the control unit 10 starts with the display data number. Data number (“001”) is set, and the first folder / file name in the folder table 101 is displayed on the display unit 12.

  Next, as described above, the highlight scrolling speed on the GUI is switched in two stages. When the scroll speed is low, the control unit 10 sets the display data number of the display management table 102, for example, at an interval of 200 msec with the internal timer of the CPU while the upper key 17 or the lower key 18 is pressed. An instruction to add or subtract “1” and reflect it on the display on the GUI is issued. When the scroll speed is high, the control unit 10 adds or subtracts “1” to the display data number of the display management table 102 at an interval of 20 msec by an internal timer of the CPU, for example, and displays it on the GUI. Give instructions to reflect.

  Details of the operation of the scrolling process will be described with reference to a flowchart comparing the time series as shown in FIG. After the control unit 10 issues a scroll instruction, if the scroll speed is high, the display data number in the display management table 102 is incremented or subtracted by “1”, and an instruction for reflecting the result on the display on the GUI is issued (step S1000), for example, wait for 19 msec (step S1001), and move the highlight up and down every 20 msec as a whole. When the scroll speed is low, the display data number in the display management table 102 is incremented or decremented by “1”, and an instruction to reflect it on the display on the GUI is issued (step S2000). (Step S2001), the highlight is moved up and down every 200 ms as a whole.

  The above is the description of the highlight scroll process on the GUI and the operation of the display process.

  The data selection process, the scroll process, and the display process described so far are performed in the control unit 10 of the sound reproduction device according to the present embodiment, so that the increase in the storage unit 11 is not hindered. It is possible to improve the operability related to the retrieval of the data stored in.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  In the above embodiment, the double tact key of the operation unit 13 is used for the up key 17 and the down key 18. However, the present invention is not limited to this, and a double tact key may be used for the left key 19 and the right key 21. A process of scrolling highlights at a constant speed when the left key 19 or the right key 21 is weakly pressed is assigned, and the highlights are scrolled at a speed faster than that when the left key 19 or the right key 21 is pressed hard. If processing is assigned, as shown in 12b of FIG. 9, the highlight 30 can be scrolled to the left or right at different speeds for items arranged in the horizontal direction on the GUI.

  In the above-described embodiment, the highlight scrolling is performed at regular intervals by measuring the elapsed time during which the up key 17 or the down key 18 is pressed. And in order to change the speed of scroll, the said fixed period interval was changed and the high-speed and low-speed scroll were switched. However, the highlight scrolling speed may be switched between high speed and low speed by adding or subtracting every few data numbers of the data to be highlighted without changing the fixed period interval.

  In the above embodiment, the storage unit 11 uses an external storage device such as a hard disk. However, it goes without saying that the present invention can be implemented using other storage media and various mass storage media to be developed in the future.
