  When selection of the button displayed on the display unit is performed using an arrow key that accepts an instruction for up / down / left / right orientation, it may be difficult for the user to know the destination of the selected button. For example, when a plurality of buttons are arranged in accordance with the QWERTY layout, which is a general keyboard button layout, there are a plurality of buttons adjacent to the button under a certain button. For this reason, the user does not know which button to move to when instructed to move downward. In order to confirm the destination, it is necessary to press an arrow key, which reduces user convenience.

  The present invention has been proposed in view of the above problems. An object of this invention is to provide the display apparatus which can improve the operativity of the user by an arrow key.

  The display device according to the present invention includes a display unit, an input processing unit, an instruction receiving unit, a selection target button selecting unit, and an index display control unit. The display unit displays a button array. The button array has a plurality of buttons, and a plurality of buttons are arranged so that a plurality of buttons adjacent to the button exist in at least one direction of a certain button. An example of the button array is a QWERTY array. The input processing means performs input processing corresponding to the selection target button in response to a predetermined input operation being performed in a selection state in which any one of the plurality of buttons is selected to be the selection target button. Execute. An example of the predetermined input operation is pressing of an OK key provided on the display device. The instruction accepting unit accepts an orientation instruction. An example of the instruction accepting unit is an arrow key that accepts an instruction of up / down / left / right directions. When the instruction receiving unit receives a direction instruction, the selection target button selecting unit selects a button that is different from the selection target button when the direction instruction is received, as a new selection target. Select as a button. The index display control means is a selection candidate button that is selected by the selection target button selection means as a new selection target button when any of the buttons is in the selected state and the instruction receiving means receives a direction instruction in the selected state. An indicator indicating such is displayed on the display unit in association with the direction received by the instruction receiving unit. Examples of the display device include a telephone, a FAX machine, a copier, and a complex machine of these.

  Thereby, the movement destination of a selection object button becomes clear about the several button which the button arrangement displayed on the display part has, and a user's operativity improves. As a specific example, the same QWERTY layout as that of a general keyboard can be adopted as a button layout without degrading the operability of the user, and an input environment familiar to the user can be provided.

  Further, the indicator display control means may display the indicator so as to overlap the selection candidate button or display adjacently. Thereby, the correspondence between the movement destination of the selection target button and the direction received by the instruction receiving unit becomes clearer. The overlapping display may be a display in which a part of the button is hidden by the index or a display in which the entire button is hidden by the index. Further, any processing procedure may be adopted as long as it is a processing procedure capable of obtaining such display.

  In addition, the selection target button selection unit is a button positioned at the other end of the button array when the instruction receiving unit receives an instruction of the direction of the one end side in a selection state where the button positioned at one end of the button array is the selection target button. The indicator display control means locates the indicator at the other end of the button array when the button located at one end of the button array is the selection target button. When the instruction accepting unit accepts an instruction of the direction of one end, it may be displayed as a new selection target button superimposed on the button selected by the selection target button selecting unit, or may be displayed adjacently.

  Embodiments will be described with reference to the drawings. FIG. 1 shows an external view and a configuration diagram of a multifunction machine 10 as an example of the display device of the present invention. The multifunction machine 10 has a printer function, a scanner function, a copy function, a facsimile function, a telephone function, and the like. As shown in the external view of FIG. 1, a liquid crystal display 50 and operation keys 52 are provided on the upper front side of the multifunction machine 10. Various screens are displayed on the liquid crystal display 50 according to the state of the multifunction machine 10. The operation key 52 is configured by an arrow key including an up key, a down key, a left key, and a right key, a numeric keypad, an OK key, and the like that receive instructions in respective directions of up, down, left, and right.

  As shown in the configuration diagram of FIG. 1, the multifunction machine 10 includes a control unit 12, a liquid crystal display 50, operation keys 52, a printing unit 54, a scanning unit 56, a FAX unit 58, a network interface 60, and the like. The control unit 12 includes a CPU 14, a ROM 16, a RAM 30, an NVRAM 40, and the like.

  The CPU 14 executes various processes according to programs stored in the ROM 16. The processing executed by the CPU 14 will be described in detail later. The ROM 16 stores a basic function program 18 for controlling basic operations of the multifunction machine 10. The basic function program 18 is used for display processing on the liquid crystal display 50, for example. The RAM 30 includes a basic function work area 32. The basic function work area 32 is a storage area for storing various data generated in the process of executing the process according to the basic function program 18. The NVRAM 40 has a basic function parameter storage area 42. The basic function parameter storage area 42 is a storage area for storing various parameters used when the CPU 14 executes processing according to the basic function program 18.

  The network interface 60 is connected to the LAN line 4. The multifunction device 10 can communicate with an externally connected personal computer and can access the Internet.

  Next, processing executed in the multifunction machine 10 will be described. 2 to 4 are flowcharts of processing executed by the CPU 14, and FIG. 2 is a flowchart related to initialization and display. In S101 of FIG. 2, the CPU 14 displays a soft keyboard. As a result, the input window 501 and the QWERTY array 502 are displayed on the liquid crystal display 50 as shown in FIG. As will be described below, the CPU 14 accepts an up / down / left / right direction instruction using the arrow keys, selects one of a plurality of buttons of the QWERTY array 502, and sets it as a selection target button. Then, the CPU 14 indicates the selection target button to the user by focusing on the selection target button. In addition, the CPU 14 selects a button as a new selection target button when an arrow key receives an instruction for the direction in a selection state in which any one of a plurality of buttons is selected to be a selection target button. By displaying an index indicating whether the selection candidate button is to be selected, the selection candidate button is clearly indicated to the user. Further, the CPU 14 executes input processing corresponding to the selection target button when, for example, an OK key is pressed in a selection state in which any one of the plurality of buttons is selected to be the selection target button. . As a result, the user can select a button with the arrow keys and enter an address or the like in the input window 501.

  The description of the flowchart will be continued. In S103, the CPU 14 performs focus initialization. Here, the basic function parameter storage area 42 of the NVRAM 40 stores correspondence information m defining the focus movement destination as shown in FIG. The correspondence information m is information indicating the correspondence between the direction accepted by the arrow key and the adjacent button for each of the plurality of buttons included in the QWERTY array 502. In this embodiment, the initial focus value is the “g” button. For this reason, the CPU 14 refers to the correspondence information m, substitutes the “g” button for the key to be selected, and substitutes 7 and 2 for the coordinates X and Y.

  In S105, the CPU 14 initializes the focus movement destination with the up key. In this embodiment, the initial value of the focus movement destination with the up key is the “y” button. Therefore, the CPU 14 refers to the correspondence information m, substitutes the “y” button for KeyU, which is a selection candidate button with the up key, and substitutes 7 and 1 for the coordinates XU and YU.

  In S107 to S111, the CPU 14 initializes the focus movement destination with the down key, the right key, and the left key, as in S105. In this embodiment, the initial values of the focus movement destinations with the down key, the right key, and the left key are the “b” button, the “h” button, and the “f” button, respectively. Therefore, the CPU 14 refers to the correspondence information m and assigns the “b” button, the “h” button, and the “f” button to the key D, Key R, and Key L, which are selection candidate buttons with the down key, the right key, and the left key, respectively. Substituting and assigning 7, 3, 8, 2, 6, 2 to the coordinates XD, YD, XR, YR, XL, YL, respectively.

  In S113, the CPU 14 highlights Key that is a selection target button. As a result, the selection target button is focused. There are various ways of focusing by highlighting. For example, when the key to be selected is the “g” button, the “g” button may be displayed enlarged and color-coded as shown in FIG. 5B.

  In S115, the CPU 14 determines whether or not YU = YMAX for the coordinate YU of the KeyU that is the selection candidate button with the up key. Here, in this embodiment, YMAX = 4 (see FIG. 6). When YU = YMAX (S115: YES), in S117, the CPU 14 displays an up arrow mark outside the upper side keyboard of the key that is the selection target button. If not YU = YMAX (S115: NO), the CPU 14 skips S117. In step S119, the CPU 14 displays an up arrow mark on the key U that is a selection candidate button with the up key, and in step S121, the CPU 14 enlarges and displays the key U that is a selection candidate button in the up key. In S123 to S145, the CPU 14 performs processing for KeyD, KeyR, and KeyL, which are selection candidate buttons with the down key, the right key, and the left key, as in S115 to S121.

  For example, KeyU, KeyD, KeyR, and KeyL that are selection candidate buttons with the up key, down key, right key, and left key are the “y” button, “b” button, “h” button, and “f” button, respectively. In this case, as shown in FIG. 5B, the marks of the up, down, right, and left arrows are displayed on each button by the processing of S115 to S145. Also, for example, KeyU, KeyD, KeyR, and KeyL, which are selection candidate buttons with the up key, down key, right key, and left key, are “:” button, “@” button, “Shift” button, “.” Button, respectively. In this case, as shown in FIG. 5C, up, down, right, and left arrow marks are displayed on each button, and a key that is a selection target key (in this case, “=”). A right arrow mark appears on the right side of the button.

  FIG. 3 is a flow relating to the movement of the coordinates of the key that is the selection target button. In S151 in FIG. 3, the CPU 14 accepts the pressing of an arrow key by the user. In S153, the CPU 14 determines whether or not the pressed arrow key is the up key. If it is the up key (S153: YES), the CPU 14 subtracts 1 from the coordinate Y of the key that is the selection target button in S155, and determines whether Y <0 for the coordinate Y in S157. . If Y <0 (S157: YES), the CPU 14 substitutes YMAX for the coordinate Y in S159. When Y <0 is not satisfied (S157: NO), the CPU 14 skips S159. In S161, the CPU 14 refers to the correspondence information m (see FIG. 6), and the button m [X, Y] having the coordinates X and Y is equal to the button assigned to the key that is the selection target button. Determine whether or not. The CPU 14 returns to S155 when the button m [X, Y] having the coordinates X and Y is equal to the button assigned to the key to be selected (S161: YES). (S161: NO), the process proceeds to S193. In S193, the CPU 14 substitutes the button m [X, Y] having the coordinates X and Y into the Key that is the selection target button.

  In S163 to S191, the CPU 14 performs processing for the down key, the right key, and the left key, as in S153 to S161. In the present embodiment, when the CPU 14 determines that the pressed arrow key is not any of the up key, the down key, the right key, and the left key (S183: NO), the CPU 14 returns to S151, and again by the user. Accepts pressing of an arrow key.

  FIG. 4 is a flow regarding the calculation of the coordinates of the selection candidate buttons KeyU, KeyD, KeyR, and KeyL. In S201 of FIG. 4, the CPU 14 substitutes the value of the coordinate X into the coordinates XU and XD of the key U and key D, which are selection candidate buttons with the up key and the down key, and is the selection candidate button with the right key and the left key. The value of the coordinate Y is substituted into the coordinates YR and YL of the KeyR and KeyL. In S203, the CPU 14 substitutes a value obtained by subtracting 1 from the coordinate Y into the coordinate YU of the KeyU that is a selection candidate button with the up key. In S205, the CPU 14 determines whether or not YU <0 for the coordinate YU. If YU <0 (S205: YES), the CPU 14 substitutes YMAX for the coordinate YU in S207. When YU <0 is not satisfied (S205: NO), the CPU 14 skips S207. In step S209, the CPU 14 refers to the correspondence information m (see FIG. 6), and the button m [XU, YU] having the coordinates XU, YU is the selection target button Key or the selection candidate button with the up key. It is determined whether or not it is equal to the button assigned to KeyU. When the button m [XU, YU] having the coordinates XU, YU is equal to the button assigned to the key that is the selection target key or the key U that is the selection candidate button with the up key (S209: YES) ), The process returns to S203, and if not equal (S209: NO), the process proceeds to S211. In S211, the CPU 14 substitutes the button m [XU, YU] having the coordinates XU, YU into KeyU, which is a selection candidate button with the up key.

  In S213 to S241, as in S203 to S211, the CPU 14 performs processing for KeyD, KeyR, and KeyL, which are selection candidate buttons using the down key, the right key, and the left key. And CPU14 returns to S113 of FIG. 2, and performs the process regarding a display again. Thereby, the movement result of the coordinates of the key that is the selection target button and the calculation result of the coordinates of the key candidates U, KeyD, KeyR, and KeyL are reflected on the display screen of the liquid crystal display 50.

  The effect of the present embodiment will be described below. In the multi-function device 10 according to the present embodiment, the CPU 14 is in a selection state in which any one of a plurality of buttons is selected and becomes a selection target button, and when any button receives an instruction for the direction of an arrow key. An arrow mark indicating whether the button is a selection candidate button to be selected as a new selection target button is displayed in association with the direction accepted by the arrow key. As a result, even if a plurality of buttons included in the QWERTY array 502 displayed on the liquid crystal display 50 are shifted from each other, the selection candidate buttons that are the movement destinations of the selection target buttons become clear. Therefore, the QWERTY layout 502 that is the same as a general keyboard can be adopted as the button layout without degrading the operability of the user, and an input environment familiar to the user can be provided.

  In the multifunction machine 10 according to the present embodiment, the CPU 14 displays an arrow mark so as to overlap the selection candidate button. Further, the CPU 14 enlarges and displays the selection candidate buttons. As a result, the correspondence between the selection candidate button that is the destination of the selection target button and the direction accepted by the arrow key becomes clearer.

  In the multifunction machine 10 according to the present embodiment, the CPU 14 selects the QWERTY array when the arrow key receives an instruction of the direction toward the one end side in a selection state where the button located at one end of the QWERTY array 502 is the selection target button. The button located at the other end of 502 is selected as a new selection target button. When the button located at one end of the QWERTY array 502 is a selection target button, the CPU 14 accepts an arrow mark and an arrow key located at the other end of the QWERTY array 502 and an instruction for the direction of one end side. In such a case, it is displayed so as to overlap the button selected as a new selection target button. For example, in a selection state in which the “=” button located at the right end of the QWERTY array 502 is a selection target button, the CPU 14 accepts an instruction that the arrow key points to the right, and the “Shift” button located at the left end of the QWERTY array 502 Is selected as a new selection target button. Then, when the “=” button located at the right end of the QWERTY array 502 is a selection target button, the CPU 14 has received an instruction that the arrow mark is located at the left end of the QWERTY array 502 and the arrow key points to the right. In this case, the “Shift” button selected as a new selection target button is displayed in addition to the “=” button and displayed outside the right-side keyboard (see FIG. 5C). Thus, when the button located at one end of the QWERTY array 502 is the selection target button, it becomes clear that the selection target button circulates and moves to the button located at the other end. Therefore, user convenience can be improved.

  In the MFP 10 according to the present embodiment, the basic function parameter storage area 42 of the NVRAM 40 indicates the correspondence between the direction accepted by the arrow key and the adjacent button for each of the plurality of buttons included in the QWERTY array 502. The correspondence information m which is information is stored (see FIG. 6). Then, in S161, S171, S181, and S191 of FIG. 3, the CPU 14 refers to the correspondence information m and substitutes the button m [X, Y] having the coordinates X and Y into the Key that is the selection target button. 4, each of the coordinates having the coordinates XU, YU, XD, YD, XR, YR, XL, YL with reference to the correspondence information m in S209, S219, S229, S239 of FIG. Buttons m [XU, YU], m [XD, YD], m [XR, YR], and m [XL, YL] are selected as the selection target button Key or the selection candidate buttons KeyU, KeyD, KeyR, and KeyL. It is determined whether or not it is equal to the assigned button. This makes it possible to handle buttons displayed in different sizes. Therefore, a button having a long horizontal shape such as a Return key or a Space key can be displayed to resemble a general keyboard, and an operation feeling close to that of a general keyboard can be given to the user. According to the multifunction machine 10 according to the present embodiment, even if a plurality of buttons included in the QWERTY array 502 displayed on the liquid crystal display 50 are shifted and arranged, it is possible to improve the user operability with the arrow keys.

  As mentioned above, although the Example of this invention was described in detail, these are only illustrations and do not limit a claim. The technology described in the claims includes various modifications and changes of the above-described embodiment. The modifications of the above embodiment are listed below.

  In the present embodiment, the correspondence information m is two-dimensional information as shown in FIG. 6, but is not limited thereto. For example, in FIG. 6, [X = 0 to 13, Y = 0] becomes [Z = 0 to 13], [X = 0 to 13, Y = 1] becomes [Z = 14 to 27], In this way, the correspondence information m may be one-dimensional information as shown in FIG. In this case, the CPU 14 substitutes the two-dimensional coordinates X and Y by substituting 35 for the coordinate Z instead of substituting 7 and 2 for the coordinates X and Y in S103 of FIG. Each process may be performed after converting into the one-dimensional coordinates of Z.

  Further, the correspondence information m may include 70 pieces of 8-byte information as shown in FIG. 7B. Here, the 0th to 2nd byte areas store a character code as button identification information assigned to each button in order to identify a plurality of buttons included in the QWERTY array 502. The area in the 3rd to 6th bytes stores the address where the character code of the destination button is stored as identification information for identifying the destination in the up key, down key, right key, and left key. . The 7th byte area stores information for identifying buttons located at the upper and lower ends of the QWERTY array 502, and the 8th byte area identifies buttons located at the right and left edges of the QWERTY array 502.
