  The touch panel 20 is a so-called resistive film type or capacitive type touch panel. The touch panel 20 is arranged on the screen D of the display unit 10 and detects contact of an icon or the like on the screen D of the display unit 10 with a contact position. When the touch panel 20 detects the contact of a finger or the like, the touch panel 20 outputs a detection signal indicating the coordinates of the contact position to an operation receiving unit 102 described later of the control unit 100. As described above, the touch panel 20 serves as an operation unit to which a user operation on the screen D of the display unit 10 is input.

  Further, the display device 1 may include a hard key in addition to the touch panel 20 as an operation unit to which a user operation is input.

  The communication unit 30 is a communication interface including a communication module such as a LAN chip (not shown).

  The storage unit 40 is a large-capacity storage device such as a RAM (Random Access Memory).

  The control unit 100 includes a processor, a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The processor is, for example, a CPU (Central Processing Unit), MCU, or ASIC. The control unit 100 functions as the control unit 101, the operation receiving unit 102, the display control unit 103, and the communication control unit 104 when the display control program stored in the storage unit 40 is executed by the processor. Note that each of the above-described constituent elements of the control unit 100 may be configured by a hardware circuit without depending on the operation based on the above-described display control program.

  The display control program is recorded on a non-transitory recording medium readable by a computer, such as a hard disk, CD-ROM, DVD-ROM, or semiconductor memory. In this case, a non-transitory recording medium readable by a computer that records the display control program is one embodiment of the present invention.

  The control unit 101 governs overall operation control of the display device 1. The control unit 101 is connected to the display unit 10, the touch panel 20, the communication unit 30, the storage unit 40, and the like. The control unit 101 controls the operation of each of the above-described components, and signals or signals between the components. Send and receive data.

  In addition, the control unit 101 serves as a processing unit that executes processing according to the operation received by the operation receiving unit 102.

  The operation reception unit 102 specifies a user operation input by the user based on the detection signal output from the touch panel 20. Then, the operation reception unit 102 receives the specified user operation and outputs a control signal corresponding to the user operation to the control unit 101, the display control unit 103, the communication control unit 104, and the like.

  The user operations include touch operations, slide operations (including flick operations and swipe operations), drag operations, pinch-out operations, pinch-in operations, and the like. For example, when the user touches the touch panel 20 with a finger and then releases the finger from the contact position, the touch panel 20 outputs a detection signal indicating the position where the contact is detected to the operation receiving unit 102. The operation reception unit 102 receives the detection signal, specifies that the user operation input by the user is a touch operation, and receives the touch operation. In addition, when the finger is moved in a state where the finger is in contact with the touch panel 20, the touch panel 20 receives a detection signal indicating each movement position from the initial position at which contact is first detected to the last position at which contact is finally detected. Output to the operation reception unit 102. The operation reception unit 102 receives the detection signal, specifies that the user operation input by the user is a slide operation, specifies the operation direction of the slide operation, and receives the slide operation.

  The communication control unit 104 has a function of controlling the communication operation of the communication unit 30. Further, the display control unit 103 has a function of controlling the display operation of the display unit 10.

  Here, in the first embodiment, a search target list 51 and an index list 52 for searching for files and data as shown in FIG. Are displayed side by side on the screen of the display unit 10. In the search target list 51, a plurality of search target items 51a indicating files and data to be searched are arranged in the vertical direction, and the index list 52 includes a plurality of items for classifying the search target items 51a. Index 52a is arranged and published in the vertical direction. Specifically, the index list 52 includes, as each index 52a, the first characters “a”, “ka”, “sa”,... In alphabetical order and the letters “A”, “ “B”, “C”,... Are listed sequentially. For example, when the character “sa” of the index 52a is selected by a touch operation, the search target list 51 includes a plurality of character strings “Nishimon” corresponding to the character “sa” of the index 52a as each search target item 51a. ”,“ Nishimon ”,“ Ashiya ”,... Are sequentially arranged from the top row in the search target list 51.

  When the index list 52 is slid in the horizontal direction orthogonal to the arrangement direction of the indexes 52a, the display control unit 103 includes a plurality of indexes 52b related to the index 52a for each index 52a. To be posted. For example, as shown in FIG. 3B, for the character “sa” in the index 52a, each character “sa” in the alphabetical order is “a” as a plurality of indexes 52b related to the character “sa” in the index 52a. "Shi", "su", "se" and "so" are posted. For example, when the character “shi” of the related index 52b is selected by a touch operation, the search target list 51 includes a plurality of character strings corresponding to the character “shi” of the index 52a as each search target item 51a. “Shimoto”, “Shimoto”, “Shioda”,... Are sequentially arranged from the top row in the search target list 51.

  Further, when the index list 52 is slid in the vertical direction, the display control unit 103 hides each index 52b related to the index 52a for each index 52a, and the index list 52 is shown in FIG. Return to the display contents.

  For this reason, the search target list 51 and the index list 52 are displayed on the screen of the display unit 10, and the area of the display area of the lists 51 and 52 is reduced. Any search target item can be quickly searched.

  Next, a configuration and processing procedure for displaying the search target list 51 and the index list 52 by the display device 1 of the first embodiment and searching for an arbitrary search target item will be described.

  FIG. 4 conceptually shows the correspondence between the indexes 52 a and 52 b, the search target items 51 a, and the search targets 53. As shown in FIG. 4, a plurality of indexes 52b are respectively associated with the plurality of indexes 52a. Each of the indexes 52a and 52b is associated with 0 or 1 to a plurality of search target items 51a. Each search target item 51a is associated with each search target 53. Each search object 53 is a file or data. Each such index 52a, 52b, each search target item 51a, and each search target 53 is stored in the storage unit 40 together with mutual association data.

  Here, when a horizontal slide operation is performed on the index list 52, the display control unit 103 posts a plurality of indexes 52b related to the index 52a for each index 52a. When any of the indexes 52a and 52b is selected by a touch operation, the display control unit 103 selects 0 or 1 to a plurality of search target items 51a associated with the touched index as a search target. Listed from the top row of list 51. Furthermore, when an arbitrary search target item 51a is selected by a touch operation, the display control unit 103 searches the search target 53 associated with the arbitrary search target item 51a to search for a file that is the search target 53 or the like. Data is displayed on the screen of the display unit 10.

  FIG. 5 is a flowchart showing a processing procedure for displaying the search target list 51 and the index list 52 and selecting an arbitrary search target item.

  First, when the user touches an icon, a touch key, or the like displayed on the screen of the display unit 10 to instruct a search for a file or data, the touch operation is received by the operation receiving unit 102 through the touch panel 20 and is controlled. The unit 101 activates a function (application program) for searching for files and data, and the display control unit 103 displays a search target list 51 and an index list 52 as shown in FIG. (Step S101).

  In this state, when an arbitrary index 52a in the index list 52 is touched and the touch operation of the arbitrary index 52a is received by the operation receiving unit 102 (“Yes” in step S102), the display control unit 103 The storage unit 40 is searched for 0 or 1 to a plurality of search target items 51a associated with an arbitrary index 52a, and the searched 0 or 1 to a plurality of search target items 51a are the first column of the search target list 51. Are sequentially displayed (step S103). When an arbitrary search target item 51a is selected by a touch operation and this touch operation is received by the operation receiving unit 102, the display control unit 103 searches the search target 53 associated with the arbitrary search target item 51a. Is searched from the storage unit 40, and the file or data that is the search target 53 is displayed on the screen of the display unit 10.

  Further, when a horizontal slide operation is performed on the index list 52 and this horizontal slide operation is received by the operation receiving unit 102 (“Yes” in step S104, “horizontal” in step S105), the display is performed. For each index 52a, the control unit 103 searches the storage unit 40 for a plurality of indexes 52b related to the index 52a and places them in the index list 52 (step S106).

  When an arbitrary index of the indexes 52a and 52b is selected by a touch operation and the touch operation of the arbitrary index is received by the operation receiving unit 102 (“Yes” in step S102), the display control unit 103 Searches the storage unit 40 for the search target item 51a associated with the arbitrary index, and sets the searched search target item 51a and the subsequent search target item 51a to the first column of the search target list 51. Are sequentially displayed (step S103). Further, when a touch operation on an arbitrary search target item 51a is received by the operation receiving unit 102, the display control unit 103 searches the storage unit 40 for a search target 53 associated with the arbitrary search target item 51a. It is displayed on the screen of the display unit 10.

  Further, when a vertical slide operation is performed on the index list 52 and this vertical slide operation is received by the operation receiving unit 102 (“Yes” in step S104, “vertical direction” in step S105), the display is performed. For each index 52a, the control unit 103 hides the plurality of indexes 52b related to the index 52a and returns the index list 52 to the display contents as shown in FIG. 3A (step S107).

  As described above, in the first embodiment, when a horizontal slide operation is performed on the index list 52, for each index 52a, a plurality of indexes 52b related to the arbitrary index 52a are placed in the index list 52, and the arbitrary When the index is touched, the search target item 51a associated with the arbitrary index is displayed from the first column of the search target list 51. For this reason, even if a large number of indexes are set, the operation procedure until a search based on an arbitrary index is executed is simple.

  In the first embodiment, when the index is touched, the display control unit 103 displays the search target item 51a associated with the index in the first column of the search target list 51. The target item 51 a may be displayed at the center position of the search target list 51.

In addition, the display control unit 103 switches between displaying and hiding each index 52b related to the index 52a according to a horizontal or vertical slide operation with respect to the index list 52. Display and non-display may be switched according to different types of user operations. For example, the display control unit 103 switches between display and non-display of each index 52b related to the index 52a in accordance with a rightward or leftward slide operation on the index list 52 or an upward or downward slide operation. Also good.
<Modification 1>

  In the first modification, as illustrated in FIG. 6A, it is assumed that the display control unit 103 displays a plurality of indexes 52b related to the index 52a on a small screen of the display unit 10 for each index 52a. As shown in FIGS. 6B and 6C, when the display control unit 103 scrolls the indexes 52a and 52b in the vertical direction, the indexes 52a and 52b are scrolled and displayed. Each search target item 51a in the target list 51 is scroll-displayed in the direction opposite to the scroll display direction of each index 52a, 52b so that the user can see all of the search target items 51a.

  FIG. 7 is a flowchart showing a processing procedure for performing such scroll display.

  First, the display control unit 103 determines, for each index 52a, whether or not a plurality of indexes 52b related to the index 52a are listed in the index list 52 (step S201). If the display control unit 103 determines that the page is posted (“Yes” in step S201), the display control unit 103 waits for a scroll operation on each of the indexes 52a and 52b (step S202).

  At this time, for example, when a downward scroll operation for each index 52a, 52b is accepted by the operation accepting unit 102 (“Yes” in step S202, “downward” in step S203), the display control unit 103 causes each index 52a to , 52b are scroll-displayed downward, and each search target item 51a in the search target list 51 is scroll-displayed upward (step S204). When an upward scroll operation for each index 52a, 52b is accepted by the operation accepting unit 102 (“Yes” in step S202, “upward” in step S203), the display control unit 103 causes each index 52a, 52b to be displayed. Is scroll-displayed upward, and each search target item 51a in the search target list 51 is scroll-displayed downward (step S205).

In addition, for each index 52a, when a plurality of indexes 52b related to the index 52a are not listed in the index list 52 (“No” in step S201), the processes of steps S202 to S205 are not performed.
Second Embodiment

  Next, a display device according to a second embodiment of the present invention will be described. Similar to the first embodiment, the display device 1 of the second embodiment has the appearance and the internal configuration shown in FIGS. 1 and 2.

  In the display device 1 according to the second embodiment, for example, when a vertical slide operation at a predetermined speed or less is performed on the index list 52 as shown in FIG. As shown in (b), the display interval of each index 52a in the index list 52 is expanded. Then, for example, when an arbitrary position in the display interval from the character “sa” of the arbitrary index 52a to the character “ta” of the next index 52a is touched, the display control unit 103 displays the search target list 51 in the search target list 51. As each search target item 51a, a plurality of character strings “Suita”, “Sui”, “Water Lilies”,... Corresponding to the arbitrary positions are sequentially arranged from the first column in the search target list 51.

  Specifically, an arbitrary position where the touch operation is performed is represented by a separation distance from the arbitrary index 52a, and each search target item 51a corresponding to the separation distance is obtained and selected. For example, as shown in FIG. 9, between the character “sa” at an arbitrary index 52a and the character “ta” at the next index 52a, The respective separation distances Sa, Si, Su, Se, and So corresponding to “shi”, “su”, “se”, and “so” are included. When the arbitrary position where the touch operation is performed is the position of the separation distance Sa (= 0) corresponding to the character “sa”, the search target list 51 includes the character “sa” as each search target item 51a. A plurality of character strings “Nishimon”, “Saimon”, “Ashiya”,... Corresponding to are sequentially arranged from the first column in the search target list 51. In addition, when the arbitrary touched position is the position of the separation distance Si corresponding to the character “shi”, the search target list 51 includes a plurality of items corresponding to the character “shi” as each search target item 51 a. Character strings “Shimoto”, “Shimoto”, “Shioda”,... Are sequentially arranged from the top row in the search target list 51.

  Further, for example, when the arbitrary position where the touch operation is performed is a position between the position of the separation distance Si corresponding to the character “shi” and the position of the separation distance Su corresponding to the character “su”, that is, arbitrary Indicates the position between the characters “shi” and “su”, the search target list 51 includes a plurality of corresponding items between the characters “shi” and “su” as the search target items 51. The character strings “Shinagawa”, “Shinagawa”,... Are sequentially arranged from the first column in the search target list 51. Furthermore, if the arbitrary position is closer to the position of the separation distance Si corresponding to the character “shi”, the character string “shi” is used as the initial character and each higher-order character string is listed as the search target item 51a. The search target list 51 is sequentially arranged from the first column. If the arbitrary position is farther from the position of the separation distance Si corresponding to the character “shi”, the character string “shi” is used as the initial character and each lower-order character string in the alphabetical order as each search target item 51a. Are sequentially arranged from the first column in the search target list 51.

  Further, when the slide operation in the vertical direction exceeding the predetermined speed is performed on the index list 52, the display interval of each index 52a in the index list 52 is narrowed and returned to the original as shown in FIG.

  For this reason, the search target list 51 and the index list 52 are displayed on the screen of the display unit 10, and the area of the display area of the lists 51 and 52 is reduced. Any search target item can be quickly searched.

  Next, a processing procedure for displaying the search target list 51 and the index list 52 by the display device 1 according to the second embodiment and searching for an arbitrary search target item will be described with reference to the flowchart shown in FIG.

  First, when a user touches an icon, a touch key, or the like on the screen of the display unit 10 to instruct a search for a file or data, the touch operation is received by the operation receiving unit 102 through the touch panel 20, and the control unit 101 Then, a function for searching for files and data is activated, and the display control unit 103 displays the search target list 51 and the index list 52 as shown in FIG. 8A on the screen of the display unit 10 (step S301). .

  In this state, when a touch operation on an arbitrary index 52a in the index list 52 is received by the operation receiving unit 102 (“Yes” in step S302), the display control unit 103 is associated with the arbitrary index 52a. Alternatively, one or more search target items 51a are searched from the storage unit 40, and the searched zero or one or more search target items 51a are sequentially displayed from the top row of the search target list 51 (step S303). When a touch operation on an arbitrary search target item 51a is received by the operation receiving unit 102, the display control unit 103 searches the storage unit 40 for a search target 53 associated with the arbitrary search target item 51a. The file or data that is the search target 53 is displayed on the screen of the display unit 10.

  In addition, when a slide operation at a predetermined speed or less is performed on the index list 52 and a slide operation at or below the predetermined speed is received by the operation receiving unit 102 (“Yes” in step S304, “Yes” in step S305), The display control unit 103 expands the display interval of each index 52a in the index list 52 as shown in FIG. 8B (step S306).

  When an arbitrary position in the display interval from the arbitrary index 52a to the next index 52a is touched and this arbitrary position is received by the operation receiving unit 102 (“Yes” in step S302), the display control unit 103 obtains a separation distance from an arbitrary index 52a to an arbitrary position, searches the storage unit 40 for a search target item 51a corresponding to the separation distance, and searches the search target item 51a and subsequent searches thereafter. The target items 51a are sequentially displayed from the top row of the search target list 51. Furthermore, when a touch operation on an arbitrary search target item 51a is received by the operation receiving unit 102, the search target 53 associated with the arbitrary search target item 51a is searched from the storage unit 40 and displayed on the screen of the display unit 10. Is displayed.

  When a slide operation exceeding a predetermined speed is performed on the index list 52 and a slide operation exceeding the predetermined speed is received by the operation receiving unit 102 (“Yes” in step S304, “No” in step S305), As shown in FIG. 8A, the display control unit 103 narrows the display interval of each index 52a in the index list 52 and restores it (step S307).

  As described above, in the second embodiment, when the speed of the slide operation on the index list 52 is equal to or lower than the predetermined speed, the display interval of each index 52a in the index list 52 is expanded, and the arbitrary display interval between the two adjacent indexes 52a is displayed. When the position is touched, the search target item 51 a corresponding to the arbitrary position is displayed from the top row of the search target list 51. For this reason, even if a large number of indexes are set, the operation procedure until a search based on an arbitrary index is executed is simple.

  In the second embodiment, the search target item 51a associated with the index 52a is displayed in the first column of the search target list 51. However, the search target item 51a is displayed at the center position of the search target list 51. It doesn't matter.

Further, the display interval of each index 52a is expanded or narrowed according to the speed of the slide operation on the index list 52, but the display interval may be switched according to other types of user operations.
<Modification 2>

In the second embodiment, the display control unit 103 scrolls and displays each index 52a when each index 52a is scrolled in the same manner as in the first modification with the display interval of each index 52a widened. At the same time, the search target items 51a in the search target list 51 may be scroll-displayed in the reverse direction so that the user can see all of the search target items 51a.
<Modification 3>

  The first embodiment and the second embodiment may be combined. For example, when the index list 52 is slid in the horizontal direction in FIG. 3A, the display control unit 103 makes a plurality of indexes 52b related to the index 52a for each index 52a as shown in FIG. 3B. Post. Then, when a vertical sliding operation at a predetermined speed or less is performed on the index list 52, the display control unit 103 increases the display interval of each index 52a in the index list 52 as shown in FIG. In this case, the display interval of all the characters in the order of the Japanese syllabary is expanded, and when any position is touch-operated in any display interval, the search target item 51a corresponding to this arbitrary position and the subsequent items are followed. Search target items 51 a are sequentially displayed from a predetermined position in the search target list 51.

  Note that the configurations and processes of the above-described embodiments and modifications described with reference to FIGS. 1 to 11 are merely examples of the present invention, and are not intended to limit the present invention to the configurations and processes.
