The up direction key 61a includes a first upper transparent area 611a and a second upper transparent area 612a. The first upper transparent region 611a is a region that is disposed to face the first upper region 601a of the first transmission film 56 and is formed in the same shape and the same size as the first upper region 601a. The second upper transparent region 612a (the hatched portion shown in FIG. 2) is a transparent region that is adjacent to the first upper transparent region 611a and is opposed to the second upper region 602a of the first transmission film 56. The down key 61b includes a first lower transparent area 611b and a second lower transparent area 612b. The first lower transparent region 611b is a region that is disposed to face the first lower region 601b of the first transmission film 56 and is formed in the same shape and size as the first lower region 601b. The second lower transparent region 612b (the hatched portion shown in FIG. 2) is a transparent region that is adjacent to the first lower transparent region 611b and is opposed to the second lower region 602b of the first transmission film 56. That is, the up direction key 61a and the down direction key 61b have an arrow shape in which the linear portion of the arrow is longer in the vertical direction than the transparent area of the up direction key 60a and the down direction key 60b of the first transmission film 56. It is an image.

  Note that the up direction keys 60a and 61a and the down direction keys 60b and 61b in this embodiment correspond to the position display unit and the operation unit of the present invention. The first upper region 601a, the first lower region 601b, the first upper transparent region 611a, the first lower transparent region 611b, the second upper transparent region 612a, and the second lower transparent region 612b in the present embodiment are the first of the present invention. This corresponds to one area. Further, the second upper region 602a and the second lower region 602b in the present embodiment correspond to the second region of the present invention.

  The cancel key 61c and the OK key 61d have the same shape and the same size as the image frame indicating the cancel key 60c and the OK key 60d of the first transparent film 56, and the inside of the frame is formed to be transparent. In FIG. 2, an area of the touch panel 54 that faces the operation keys 60 a to 61 d is surrounded by a dotted line. In addition, the cancel key 61c and the OK key 61d may be formed such that the frame of the image and the characters or figures are transparent, like the cancel key 60c and the OK key 60d of the first transparent film 56.

The LEDs 66 a to 66 d are arranged on the display adjacent surface 511 of the substrate 51. Specifically, the LED 66a is disposed at a position facing the up direction keys 60a and 61a, and the LED 66b is disposed at a position facing the down direction keys 60b and 61b. The LED 66c is disposed at a position facing the cancel keys 60c and 61c, and the LED 66d is disposed at a position facing the OK keys 60d and 61d. The LEDs 66a to 66d have three light emission patterns having different light luminances. In the present embodiment, the three light emitting patterns are arranged in the order of decreasing light luminance, light emitting pattern A (for example, luminance 15 cd / m ² ), light emitting pattern B (for example, luminance 35 cd / m ² ), light emitting pattern C (for example, luminance 50 cd). / M ² ).

  The diffusion plates 68a to 68d are arranged at positions facing the LEDs 66a to 66d, respectively, and diffuse light from the LEDs 66a to 66d. When the LEDs 66a to 66d are turned on, the light is diffused by each of the diffusion plates 68a to 68d and transmitted through the region indicating the operation keys 61a to 61d of the second transmission film 58, and then the operation keys 60a to 60d of the first transmission film 56. It penetrates the area showing. Thereby, the user can visually recognize each operation key 60a-61d from the touch panel 54 surface side.

  Part of the light transmitted through the second upper transparent region 612a and the second lower transparent region 612b of the second transmission film 58 passes through the second upper region 602a and the second lower region 602b of the first transmission film 56. The intensity of light transmitted through the second upper region 602a and the second lower region 602b increases as the luminance of the light from the LEDs 66a and 66b increases. That is, as the luminance of the light of the LEDs 66a and 66b increases, the upper key 61a and the lower key 61b indicated by the transparent regions 611a, 612a, 611b, and 612b of the second transmission film 58 are visually recognized from the surface side of the touch panel 54. Increases nature.

  In the present embodiment, when the light intensity transmitted through the second upper region 602a or the second lower region 602b of the first transmission film 56 in the light based on the light emission pattern is less than a predetermined value (for example, 0.5 mcd), it is determined by the user. Assume that the transmitted light is not visible. However, since the light intensity at which the user cannot see the transmitted light depends on the usage environment of the MFP 1, the predetermined value is appropriately set at the time of design.

  In the present embodiment, when the LEDs 66a to 66d are lit with the low-luminance light emission pattern A, most of the light transmitted through the second upper transparent region 612a and the second lower transparent region 612b is the second upper region 602a and the second upper region 602a. It does not pass through the lower region 602b. That is, in such a case, the light intensity transmitted through the second upper region 602a or the second lower region 602b is less than a predetermined value. Therefore, the user visually recognizes the upward key 60a and the downward key 60b indicated by the transparent regions 601a and 601b of the first transparent film 56 from the surface side of the touch panel 54 (for example, the upper side shown in FIG. 5B). Direction keys 60a and 61a).

  When the LEDs 66a to 66d are lit in the light emission pattern B, part of the light transmitted through the second upper transparent region 612a and the second lower transparent region 612b passes through the second upper region 602a and the second lower region 602b. That is, in such a case, the light intensity transmitted through the second upper region 602a or the second lower region 602b is equal to or higher than a predetermined value. For this reason, the user visually recognizes the upward key 61a and the downward key 61b indicated by the transparent regions 611a, 612a, 611b, and 612b of the second transparent film 58 from the surface side of the touch panel 54 (for example, FIG. ) (See the downward keys 60b and 61b). Of the up key 61a and the down key 61b that are visible in such a case, the second upper transparent region 612a and the second lower transparent region 612b have light intensities that pass through the second upper region 602a and the second lower region 602b. The intensity of light transmitted through the first upper region 601a and the first lower region 601b is smaller. Therefore, the second upper transparent area 612a and the second lower transparent area 612b of the up key 61a and the down key 61b are displayed darker than the other areas.

  When the LEDs 66a to 66d are lit in the light emission pattern C, part of the light transmitted through the second upper transparent region 612a and the second lower transparent region 612b passes through the second upper region 602a and the second lower region 602b. That is, in such a case, the light intensity transmitted through the second upper region 602a or the second lower region 602b is equal to or higher than a predetermined value, and is larger than that in the case of the light emission pattern B. For this reason, the user visually recognizes the up direction key 61a and the down direction key 61b indicated by the transparent regions 611a, 612a, 611b, and 612b of the second transmissive film 58 from the front surface side of the touch panel 54. In such a case, the light intensity transmitted through the second upper region 602a and the second lower region 602b is larger than that in the case of the light emission pattern B. For this reason, the second upper transparent region 612a and the second lower transparent region 612b are displayed more clearly than in the case of the light emission pattern B (for example, refer to the downward keys 60b and 61b shown in FIG. 5A).

  The CPU 10 controls each function of the MFP 1 according to fixed values and programs stored in the ROM 11, RAM 12, or flash memory 13, and controls each unit connected to the input / output port 92. The CPU 10 displays various information such as image data stored in the storage medium loaded in the slot unit 80 on the touch panel display unit 50 and causes the printer unit 20 to print the various information. The CPU 10 displays various virtual screens 70 on the display 52 based on screen data stored in a coordinate management memory 130 described later, and items A to J displayed on each virtual screen 70 in the detection area 541 of the touch panel 54. An area corresponding to (see FIG. 4) is set as a reaction area corresponding to the items A to J.

  The ROM 11 is a non-rewritable memory that stores a control program 110 executed by the MFP 1 and a luminance memory 112. The CPU 10 executes display control processing and selection item display processing shown in the flowcharts of FIGS. 7 and 8 according to the control program 110. In the ROM 11, the coordinate information of the operation keys 60a to 61d on the touch panel 54, the processing associated with each operation key 60a to 61d, and the LEDs 66a to 66d corresponding to the operation keys 60a to 61d are the above four operations. The keys 60a to 61d are stored in association with key identification information respectively indicating the keys 60a to 61d. Further, processing associated with various operation buttons provided in the operation unit 40 is stored in association with button identification information indicating each operation button. As long as the key identification information and the button identification information can be identified, such as the numbers assigned to the operation keys 60a to 61d and the operation buttons, various forms can be adopted.

  The luminance memory 112 is a memory area that stores the three light emission patterns of the LEDs 66a to 66d and the luminance of the LEDs 66a to 66d corresponding to the respective light emission patterns in association with each other.

  The RAM 12 is a rewritable volatile memory for temporarily storing various information. The RAM 12 stores the contact position of the input medium detected by the touch panel 54.

  The flash memory 13 is a rewritable nonvolatile memory, and stores parameters relating to various functions such as a copy function, a scanner function, and a printer function, for example. The flash memory 13 includes a coordinate management memory 130 and a selection number memory 132 (corresponding to the number storage unit of the present invention). The flash memory 13 stores a first threshold value L1 and a second threshold value L2, which will be described later.

  The coordinate management memory 130 is a memory area that stores screen data based on a plurality of virtual screens 70 displayed on the display surface 521 of the display 52. In the coordinate management memory 130, each screen data, the screen size of each virtual screen 70, the coordinate information of various items A to J (see FIG. 4) included in each virtual screen 70, and the items A to J are associated. The processed processing is stored in association with the screen identification information indicating each virtual screen 70. The screen identification information may take various forms as long as the plurality of virtual screens 70 can be identified, such as numbers assigned to the virtual screens 70, for example.

  In the present embodiment, the virtual screen 70 is a screen that is displayed on the display surface 521 of the display 52 and includes various information such as characters and images. The virtual screen 70 is, for example, an image in which thumbnail images are arranged at predetermined positions, an Internet homepage, or the like (see FIG. 4). The virtual screen 70 includes a screen whose screen size is larger than the display surface 521 of the display 52. For example, when the virtual screen 70 is longer in the vertical direction than the display surface 521 of the display 52, only a part of the virtual screen 70 is displayed on the display surface 521 of the display 52. In such a case, the display areas 71 to 74 (see FIG. 4) of the virtual screen 70 displayed on the display surface 521 are moved in the vertical direction based on the operation of the up direction keys 60a and 61a or the down direction keys 60b and 61b by the user. Thus, the user can visually recognize the entire virtual screen 70.

  In the present embodiment, items A to J are image data that can be selected by the user, such as icons included in the virtual screen 70. As shown in FIG. 4, the coordinate information of the items A to J is directed toward the virtual screen 70 in the right direction (X direction shown in FIG. 4) and the downward direction (Y direction shown in FIG. 4) with the upper left as the origin. The values are attached so that they are continuous. The coordinate information becomes larger toward the right direction and the lower direction of the virtual screen 70. The coordinate information of the items A to J can acquire the area where the items A to J are arranged, such as the center coordinates of the items A to J and the sizes of the items A to J, or the coordinates of the four corners of the items A to J. Any information is sufficient. In addition, when the screen configuration is changed such as addition of items or change of arrangement in each virtual screen 70 by a user operation or the like, various information stored in association with the screen identification information of the virtual screen 70 is used to change the screen configuration. Will be updated accordingly.

  In the coordinate management memory 130, key identification information of valid keys corresponding to each virtual screen 70 is stored in association with the screen identification information of the virtual screen 70. The valid key corresponding to the virtual screen 70 is an operation key associated with processing that can be executed in a state where the virtual screen 70 is displayed on the display surface 521 among the cancel keys 60c and 61c and the OK keys 60d and 61d. It is. In the present embodiment, when the items A to J are included in the virtual screen 70, the processing associated with the cancel keys 60c and 61c can be executed, and the processing associated with the OK keys 60d and 61d includes items A to J. It is controlled to be executable when selected. That is, the valid keys corresponding to the virtual screen 70 are the cancel keys 60c and 61c. On the other hand, when the items A to J are not included in the virtual screen 70, the valid keys corresponding to the virtual screen 70 are the cancel keys 60c and 61c and the OK keys 60d and 61d. The case where the items A to J are not included in the virtual screen 70 is a case where the virtual screen 70 is configured only by characters or images that cannot be selected such as a message.

  In the present embodiment, only valid keys corresponding to the virtual screen 70 displayed on the display surface 521 are displayed. That is, in the present embodiment, only the LEDs 66c and 66d corresponding to the valid keys are lit. Thereby, the user can easily recognize the process that can be performed on the virtual screen 70 displayed on the display surface 521, and the erroneous operation by the user can be reduced. When the items A to J are included in the virtual screen 70, the LEDs 66d corresponding to the OK keys 60d and 61d are turned on when the items A to J are selected (see S752 shown in FIG. 7). Thereby, since the OK keys 60d and 61d can be displayed only when the processing associated with the OK keys 60d and 61d can be executed, the operability for the user can be further improved.

  The selection count memory 132 is a memory area that stores the number of selections made by the user for each item displayed on each virtual screen 70. In the selection count memory 132, the items A to J, the selection count of the items A to J, and the screen identification information of the virtual screen 70 including the items A to J are stored in association with each other. Based on the coordinate information stored in the coordinate management memory 130, the CPU 10 adds one by one the number of selections of the items A to J corresponding to the coordinate information corresponding to the contact position detected by the touch panel 54, and the selection number memory 132. To remember.

  In the present embodiment, when there are items whose number of selections is greater than or equal to a predetermined number among the items A to J included in each virtual screen 70, the CPU 10 selects the item with the maximum number of selections among the items A to J as the maximum selection item. (Corresponding to setting means of the present invention). Then, the set maximum selection item and the coordinate information of the maximum selection item are stored in the flash memory 13 in association with the screen identification information of the virtual screen 70. The maximum selection item is set every time the selection count stored in the selection count memory 132 is updated. Further, the coordinate information of the maximum selection item stored in the flash memory 13 is updated according to the change in the screen configuration of the virtual screen 70.

<Operation of Embodiment>
The operation of the MFP 1 according to the first embodiment will be described in detail with reference to FIGS.

(Display control processing)
Display control processing executed by the CPU 10 of the MFP 1 will be described with reference to FIGS. 4, 5, and 7. This display control process is a process started when a screen display instruction is received by a user operation. The screen display instruction reads the screen data stored in the coordinate management memory 130 based on the input of the power button, the cancel keys 60c and 61c, the OK keys 60d and 61d, and displays the virtual screen 70 based on the screen data. This is an instruction to cause the CPU 10 to execute processing to be newly displayed on the surface 521.

  First, in step 700 shown in FIG. 7 (hereinafter, step is denoted as S), the CPU 10 determines whether or not the screen size of the virtual screen 70 displayed on the display 52 is larger than the display surface 521 based on the screen display instruction. To do. When it is determined that the screen size of the virtual screen 70 displayed on the display 52 based on the screen display instruction is equal to or smaller than the size of the display surface 521 (S700: NO), the CPU 10 stores the screen stored in the coordinate management memory 130. Based on the data, the virtual screen 70 is displayed on the display surface 521 (S702).

  Based on the coordinate management memory 130, the CPU 10 turns on the LEDs 66c and 66d of the valid keys corresponding to the virtual screen 70 displayed in S702 (S704), and proceeds to step S742. In the present embodiment, the LEDs 66c and 66d corresponding to the cancel keys 60c and 61c and the OK keys 60d and 61d are turned on with the light emission pattern C. In S <b> 704, for example, in FIG. 5A, the CPU 10 lights the LED 66 c corresponding to the cancel keys 60 c and 61 c with the light emission pattern C as the valid key LED corresponding to the virtual screen 70.

  When it is determined that the screen size of the virtual screen 70 displayed on the display 52 based on the screen display instruction is larger than the display surface 521 (S700: YES), the CPU 10 stores the screen of the virtual screen 70 stored in the coordinate management memory 130. Based on the data, an area corresponding to the size of the display surface 521 from the upper end of the virtual screen 70 is displayed on the display surface 521 as a display area (S706).

  In the present embodiment, the virtual screen 70 shown in FIG. 4 will be described as an example of the virtual screen 70 larger than the display surface 521 of the display 52 that is displayed based on the screen display instruction received at the start of the main display control process.

  The virtual screen 70 illustrated in FIG. 4 includes rectangular items A to J. Regions 71 to 74 surrounded by broken lines in FIG. 4 are display regions displayed on the display surface 521. The display areas 71 to 74 have the same size as the display surface 521 and include two items each in the X direction and the Y direction, that is, a total of four items A to J.

  The display areas 71 to 74 are moved downward by half of the length in the Y direction in the display areas 71 to 74 every time the user selects the down direction keys 60b and 61b. That is, in the state where the display area 71 is displayed on the display surface 521 (see FIG. 5A), every time selection of the down direction keys 60b and 61b is detected, the display area 721 (see FIG. 5B), a display area 73 (see FIG. 5C), and a display area 74 (see FIG. 5D) are sequentially displayed. Similarly, the display areas 71 to 74 are moved upward by half the length of the display areas 71 to 74 in the Y direction each time the up direction keys 60 a and 61 a are selected by the user. In other words, in the state where the display area 74 is displayed on the display surface 521 (see FIG. 5D), every time selection of the up direction keys 60a and 61a is detected, the display area 73 and the display area are displayed on the display surface 521. An area 72 and a display area 71 are displayed in order. In S <b> 706, the CPU 10 displays the display area 71 corresponding to the size of the display surface 521 from the upper end of the virtual screen 70 on the display surface 521 (see FIG. 5A).

  Based on the coordinate management memory 130, the CPU 10 turns on the LEDs 66c and 66d of the valid keys corresponding to the virtual screen 70 displayed in S706 (S708). For example, as shown in FIG. 5A, the LED 66c corresponding to the cancel keys 60c and 61c is lit in the light emission pattern C.

  The CPU 10 determines whether or not the maximum selection item associated with the screen identification information of the virtual screen 70 displayed in S706 is stored in the flash memory 13 (S710). When it is determined that the maximum selection item is stored (S710: YES), the CPU 10 executes a selection item display process (S712), and the process proceeds to S742. The selection item display process (S712) will be described in detail later.

  When it is determined that the maximum selection item is not stored (S710: NO), the CPU 10 calculates the distance Lu from the upper end of the display areas 71 to 74 to the upper end of the virtual screen 70 (S714). For example, as shown in FIG. 5B, when the display area 72 of the virtual screen 70 is displayed on the display surface 521, the distance Lu from the upper end of the display area 72 to the upper end of the virtual screen 70 is as shown in FIG. It becomes the distance U2 shown.

  The CPU 10 determines whether or not the distance Lu calculated in S714 is larger than the first threshold L1 (S716). The first threshold L1 is the length in the vertical direction (Y direction shown in FIG. 4) in the display areas 71 to 74 that can be displayed on the display surface 521. That is, the first threshold L1 is, for example, the same length as the distance D2 shown in FIG. When it is determined that the distance Lu is greater than the first threshold L1 (S716: YES), the CPU 10 lights the LED 66a corresponding to the up direction key 60a, 61a with the light emission pattern C (S718), and the step process proceeds to S728. To do.

  When it is determined that the distance Lu is equal to or smaller than the first threshold L1 (S716: NO), the CPU 10 determines whether or not the distance Lu is greater than the second threshold L2 (S720). The second threshold L2 is half the length in the vertical direction (Y direction shown in FIG. 4) in the display areas 71 to 74 that can be displayed on the display surface 521. That is, the second threshold value L2 is a distance that moves each time the up direction key 60a, 61a or the down direction key 60b, 61b is selected, and has the same length as the distance U2 shown in FIG. 4, for example. When it is determined that the distance Lu is greater than the second threshold value L2 (S720: YES), the CPU 10 lights the LED 66a corresponding to the upward key 60a, 61a with the light emission pattern B (S722), and the step process proceeds to S728. To do.

  When it is determined that the distance Lu is equal to or smaller than the second threshold L2 (S720: NO), the CPU 10 determines whether or not the distance Lu is 0 (S724). When it is determined that the distance Lu is 0 (S724: YES), the CPU 10 shifts the step process to S728. When it is determined that the distance Lu is not 0, that is, the distance Lu is greater than 0 and less than or equal to the second threshold value L2 (S724: NO), the CPU 10 displays the LED 66a corresponding to the up direction keys 60a and 61a in the light emission pattern A. Lights up (S726).

  The CPU 10 calculates a distance Ld from the lower end of the display areas 71 to 74 to the lower end of the virtual screen 70 (S728). For example, as shown in FIG. 5B, when the display area 72 of the virtual screen 70 is displayed on the display surface 521, the distance Ld from the lower end of the display area 72 to the lower end of the virtual screen 70 is as shown in FIG. It becomes the distance D2 shown.

  The CPU 10 determines whether or not the distance Ld calculated in S728 is larger than the first threshold L1 (S730). When it is determined that the distance Ld is greater than the first threshold L1 (S730: YES), the CPU 10 lights the LED 66b corresponding to the down key 60b, 61b with the light emission pattern C (S732), and the step process proceeds to S742. To do.

  When it is determined that the distance Ld is equal to or less than the first threshold L1 (S730: NO), the CPU 10 determines whether or not the distance Ld is greater than the second threshold L2 (S734). When it is determined that the distance Ld is greater than the second threshold L2 (S734: YES), the CPU 10 lights the LED 66b corresponding to the down key 60b, 61b with the light emission pattern B (S736), and the step process proceeds to S742. To do.

  When it is determined that the distance Ld is equal to or smaller than the second threshold L2 (S734: NO), the CPU 10 determines whether or not the distance Ld is 0 (S738). When it is determined that the distance Ld is 0 (S738: YES), the CPU 10 shifts the step process to S742. When it is determined that the distance Ld is not 0 (S738: NO), the CPU 10 turns on the LED 66b corresponding to the down direction keys 60b and 61b with the light emission pattern A (S740).

  The CPU 10 determines whether or not an operation by the user has been performed (S742). Specifically, the CPU 10 has detected that the touch panel 54 detects a contact at a position corresponding to the items A to J or the operation keys 60 a to 61 d displayed on the display surface 521 in the detection area 541, or the operation unit 40. It is determined whether the input from is accepted. When it is determined that no operation is performed by the user (S742: NO), the CPU 10 repeats step S742 until the operation is performed.

  If it is determined that an operation by the user has been performed (S742: YES), the CPU 10 determines whether the operation determined to be performed by the user in S742 is an operation on the direction key (S744). Here, the direction key is the up direction key 60a, 61a or the down direction key 60b, 61b. That is, the operation on the direction key is a contact at a position corresponding to the upward key 60a, 61a or the downward key 60b, 61b in the detection area 541 of the touch panel 54.

  When it is determined that the operation determined in S742 is an operation for the direction key (S744: YES), the CPU 10 selects the direction key from the display areas 71 to 74 of the virtual screen 70 displayed on the display surface 521. The display areas 71 to 74 moved by a predetermined amount in the corresponding direction are displayed on the display surface 521 (S746), and the process proceeds to S710. For example, when the direction keys determined in S744 are the upward keys 60a and 61a, the CPU 10 moves the display areas 71 to 74 moved upward by a predetermined amount from the display areas 71 to 74 displayed on the display surface 521. Is displayed. Further, when the direction keys determined in S744 are the downward keys 60b and 61b, the CPU 10 moves the display areas 71 to 74 moved downward by a predetermined amount from the display areas 71 to 74 displayed on the display surface 521. Is displayed. Note that the predetermined amount is half the length in the Y direction in the display areas 71 to 74.

  When it is determined that the operation determined in S742 is not an operation for the direction key (S744: NO), the CPU 10 determines whether the operation is an operation for the items A to J (S748). Here, the operations on the items A to J are selection of the items A to J by the user, that is, contact of positions on the detection area 541 corresponding to the items A to J displayed on the display surface 521.

  When it is determined that the operation determined in S742 is an operation for the items A to J (S748: YES), the CPU 10 stores the selection count stored in association with the operated items A to J in the selection count memory 132. Is updated by adding 1 (S750). Then, the CPU 10 turns on the LED 66d corresponding to the OK keys 60d and 61d (S752), and proceeds to step S742.

  When it is determined that the operation determined in S742 is not an operation for the items A to J (S748: NO), the CPU 10 executes a process stored in the ROM 11 in association with the operation (S756), and performs this process. finish.

  Here, the display control process shown in FIG. 7 will be described using FIGS. 4 and 5 as an example. In the present embodiment, it is assumed that a screen display instruction for displaying the virtual screen 70 illustrated in FIG. 4 is received by a user operation. Valid keys corresponding to the virtual screen 70 shown in FIG. 4 are cancel keys 60c and 61c. Further, it is assumed that there is no item whose number of selections is greater than or equal to a predetermined number among the items A to J of the virtual screen 70. That is, it is assumed that the maximum selection item associated with the screen identification information of the virtual screen 70 is not stored in the flash memory 13. In FIG. 5, for convenience of explanation, display forms of the operation keys 60 a to 61 d by light based on the light emission pattern C (for example, the downward keys 60 b and 61 b shown in FIG. 5A) are indicated by bold lines.

  First, since the virtual screen 70 shown in FIG. 4 is larger than the display surface 521 (S700: YES), the display area 71 for the display surface 521 is displayed from the upper end of the virtual screen 70 (S706) (see FIG. 5A). . Then, the LEDs 66c of the cancel keys 60c and 61c, which are valid keys corresponding to the virtual screen 70, are turned on with the light emission pattern C (S708).

  Since the maximum selection item is not stored (S710: NO), the step process proceeds to S714. As shown in FIG. 4, since the upper end of the display area 71 and the upper end of the virtual screen 70 are at the same position, the distance Lu is 0 (S724: YES), and the up direction keys 60a and 61a are not displayed (FIG. 5A). reference). In addition, the distance Ld from the lower end of the display area 71 to the lower end of the virtual screen 70 is the distance D1 (see FIG. 4) and is larger than the first threshold L1 (S730: YES), so the LEDs 66b of the down keys 60b and 61b Lights up at C (S732). Therefore, as shown in FIG. 5A, the down direction keys 60b and 61b are in the shape of the down direction key 61b shown by the transparent regions 611b and 612b of the second transmission film 58, and in the case of the light emission pattern B (for example, The display is clearer than the downward keys 60b and 61b) shown in FIG.

  Here, it is assumed that the user selects the down keys 60b and 61b, that is, the contact of the position on the detection area 541 corresponding to the down keys 60b and 61b is detected (S742: YES, S744: YES). In such a case, as shown in FIG. 5B, the display area 72 moved downward by a predetermined amount from the display area 71 of the virtual screen 70 is displayed on the display surface 521 (S746). The distance Lu from the upper end of the display area 72 to the upper end of the virtual screen 70 is the distance U2 (see FIG. 4), which is the same length as the second threshold L2 (S724: NO), so the LEDs 66a of the up direction keys 60a and 61a. Is turned on with the light emission pattern A (S726). Further, since the distance Ld from the lower end of the display area 72 to the lower end of the virtual screen 70 is the distance D2 (see FIG. 4) and has the same length as the first threshold L1 (S734: YES), the down keys 60b and 61b LED 66b is turned on with the light emission pattern B (S732). Therefore, as shown in FIG. 5B, the upward keys 60a and 61a are displayed in the shape of the upward key 60a indicated by the transparent area 601a of the first transparent film 56. Further, the down direction keys 60b and 61b are in the shape of the down direction key 61b indicated by the transparent areas 611b and 612b of the second transmission film 58, and in the case of the light emission pattern C (for example, the down direction shown in FIG. 5A). The keys 60b and 61b) are displayed darker.

  When the down key 60b or 61b is selected by the user (S742: YES, S744: YES), as shown in FIG. 5C, the predetermined amount is moved downward from the display area 72 of the virtual screen 70. The displayed area 73 is displayed on the display surface 521 (S746). Since the distance Lu from the upper end of the display area 73 to the upper end of the virtual screen 70 is the distance U3 (see FIG. 4) and is the same length as the first threshold L1 (S720: YES), the LEDs 66a of the up direction keys 60a and 61a. Is turned on with the light emission pattern B (S726). Further, since the distance Ld from the lower end of the display area 73 to the lower end of the virtual screen 70 is the distance D3 (see FIG. 4), which is the same length as the second threshold L2 (S738: NO), the down keys 60b and 61b. LED 66b is turned on with the light emission pattern A (S732). Therefore, as shown in FIG. 5C, the up direction keys 60a and 61a are displayed in the shape of the up direction key 61a indicated by the transparent regions 611a and 612a of the second transmission film 58. The downward keys 60b and 61b are displayed in the shape of the downward key 60b indicated by the transparent area 601b of the first transmission film 56.

  When the down key 60b, 61b is selected by the user (S742: YES, S744: YES), as shown in FIG. 5 (D), a predetermined amount is moved downward from the display area 73 of the virtual screen 70. The displayed area 74 is displayed on the display surface 521 (S746). Since the distance Lu from the upper end of the display area 74 to the upper end of the virtual screen 70 is the distance U4 (see FIG. 4) and is larger than the first threshold L1 (S716: YES), the LED 66a of the up direction keys 60a and 61a is the light emission pattern C. Lights up (S726). Therefore, as shown in FIG. 5D, the up direction keys 60a and 61a are in the shape of the up direction key 61a shown by the transparent regions 611a and 612a of the second transmission film 58, and more than the case of the light emission pattern B. It is displayed clearly. Further, since the distance Ld from the lower end of the display area 74 to the lower end of the virtual screen 70 is 0 (S738: YES), the down keys 60b and 61b are not displayed (see FIG. 5D).

  Here, it is assumed that the item J is selected by the user, that is, contact of a position on the detection area 541 corresponding to the item J displayed on the display surface 521 is detected (S742: YES, S748: YES). FIG. 5E shows a state in which the item J is selected by the user, and the item J is indicated by a bold line. The display form of the selected item can take various forms as long as the item is a display form that can be visually recognized by the user.

  In this case, the number of selections stored in association with the item J of the selection number memory 132 is incremented by 1 (S752), and the LED 66d corresponding to the OK keys 60d and 61d is turned on with the light emission pattern C (S752). Therefore, OK keys 60d and 61d are displayed (see FIG. 5E). If the OK keys 60d and 61d are selected by the user (S742: YES, S748: NO), the process stored in the ROM 11 in association with the OK keys 60d and 61d is executed (S756), and this process ends. To do.

  As described above, according to the present embodiment, the LEDs 66 a to 66 d emit light according to the distance between the end of the virtual screen 70 and the display areas 71 to 74 of the virtual screen 70 displayed on the display surface 521. Patterns A to C are switched (see FIG. 7). In response to the switching of the light emission patterns A to C, the up direction keys 60a and 61a and the down direction keys 60b and 61b are used as the up direction key 61a indicated by the transparent areas 611a, 612a, 611b, and 612b of the second transmission film 58. The display shape of the down direction key 61b and the display shape of the up direction key 60a and the down direction key 60b indicated by the transparent regions 601a and 601b of the first transmission film 56 are switched (see FIG. 5). The display shapes of the up direction key 61a and the down direction key 61b are specifically the areas 601a, 602a, 601b, and 602b formed on the first transmission film 56 and the areas 611a and 611a formed on the second transmission film 58. It is a shape displayed by transmitting light through 612a, 611b, and 612b. In addition, the display shapes of the up direction key 60a and the down direction key 60b are specifically determined by the light passing through the areas 601a and 601b formed on the first transmission film 56 and the areas 611a and 611b formed on the second transmission film 58. It is a shape displayed by transmitting.

  Therefore, the user confirms the display of the up direction keys 60a and 61a and the down direction keys 60b and 61b, and thereby the distance Lu from the display areas 71 to 74 displayed on the display surface 521 to the end of the virtual screen 70. , Ld can be recognized. Therefore, when displaying the virtual screen 70 (see FIG. 4) larger than the display surface 521 of the display 52, the positions of the display areas 71 to 74 displayed on the display surface 521 with respect to the virtual screen 70 can be easily recognized. it can.

  In general, when the positions of the display areas 71 to 74 displayed on the display surface 521 with respect to the virtual screen 70 are recognized by displaying a scroll bar or the like on the display surface 521, the information that can be displayed on the display surface 521 is scrolled. It is reduced by the display area such as a bar. However, in this embodiment, the up direction keys 60a and 61a and the down direction keys 60b and 61b are provided in areas 561 and 581 adjacent to the areas 562 and 582 facing the display 52 (see FIG. 2). For this reason, more information can be displayed on the display surface 521. In particular, when the size of the display 52 is small, it is preferable to provide the upward keys 60a and 61a and the downward keys 60b and 61b in areas different from the display as in the present embodiment.

  The up direction keys 60a and 61a include a first upper area 601a, a first upper transparent area 611a, a second upper transparent area 612a, and a second upper area 602a (see FIG. 2). Similarly, the downward keys 60b and 61b are composed of a first lower region 601b, a first lower transparent region 611b, a second lower transparent region 612b, and a second lower region 602b. The second upper region 602a and the second lower region 602b have different light transmittances from other transparent regions. Moreover, LED66a-66d has the three light emission patterns A, B, and C from which the brightness | luminance of light differs.

  As a result, the up direction keys 60a and 61a and the down direction keys 60b and 61b correspond to the first upper area 601a and the second upper area 602a, and the first lower area 601b and the second lower area 602b according to the luminance of light. And a display shape in which the first upper region 601a and the first lower region 601b are displayed (see FIG. 5). The display shape in which the first upper region 601a and the second upper region 602a, and the first lower region 601b and the second lower region 602b are displayed is the second transmission film by light based on the light emission pattern B or the light emission pattern C. The display shapes of the up direction key 61a and the down direction key 61b indicated by 58 transparent regions 611a, 612a, 611b, and 612b. The display shape in which the first upper area 601a and the first lower area 601b are displayed is the upward key 60a and the downward direction indicated by the transparent areas 601a and 601b of the first transmission film 56 by light based on the light emission pattern A. This is the display shape of the key 60b. Therefore, the user confirms the display of the up direction keys 60a and 61a and the down direction keys 60b and 61b, and thereby the distance Lu from the display areas 71 to 74 displayed on the display surface 521 to the end of the virtual screen 70. , Ld can be easily recognized.

  Of the upward keys 60a and 61a, the first upper region 601a, the first upper transparent region 611a, and the second upper transparent region 612a are arrow-shaped regions indicating the upward direction, and are compared to the second upper region 602a. It is formed so as to increase the light transmittance (see FIG. 2). Similarly, the first lower region 601b, the first lower transparent region 611b, and the second lower transparent region 612b of the downward keys 60b and 61b have an arrow shape indicating the downward direction, and the second lower region 602b. It is formed to be transparent so that the light transmittance is higher than that (see FIG. 2). In addition, as the distances Lu and Ld between the end portion of the virtual screen 70 and the display areas 71 to 74 are longer, the light emission pattern is switched to a light emission pattern (see S716 to S726 and S730 to S740 shown in FIG. 5).

  Therefore, the area indicating the upper direction and the lower direction among the upper direction keys 60a and 61a and the lower direction keys 60b and 61b has a high light transmittance, and is therefore displayed by light based on all the light emission patterns A to C (FIG. 5). Thereby, it is possible to reliably recognize in which direction of the display areas 71 to 74 the virtual screen 70 extends.

  The light intensity transmitted through the second upper region 602a or the second lower region 602b is longer as the distances Lu and Ld between the end of the virtual screen 70 and the display regions 71 to 74 displayed on the display surface 521 are longer. ,growing. Therefore, as the distances Lu and Ld are longer, the second upper area 602a or the second lower area 602b is displayed more clearly, so that the upper direction keys 60a and 61a or the lower direction keys 60b and 61b are displayed larger and clearer. . Therefore, the user confirms the size of the direction keys 60a, 61a, 60b, 61b, and determines the distances Lu, Ld from the display areas 71-74 displayed on the display surface 521 to the end of the virtual screen 70, respectively. It can be recognized more easily.

  The touch panel display unit 50 is configured such that the touch panel 54 is overlaid on the first transmissive film 56 and the second transmissive film 58 showing the direction keys 60a, 61a, 60b, and 61b. Accordingly, the display areas 71 to 74 can be moved according to the positions of the display areas 71 to 74 with respect to the virtual screen 70 only by touching the display portions of the direction keys 60a, 61a, 60b, and 61b. Therefore, the entire virtual screen 70 can be easily viewed by the user.

(Selected item display processing)
Next, the selection item display process (S712) executed by the CPU 10 of the MFP 1 will be described with reference to FIG. 4, FIG. 6, and FIG. This selection item display processing is performed using direction keys in accordance with the distance from the display areas 71 to 74 of the virtual screen 70 displayed on the display surface 521 to the maximum selection item among the items A to J of the virtual screen 70. This is a process for controlling the display of 60a, 61a, 60b, 61b.

  First, the CPU 10 acquires the coordinate information of the maximum selection item stored in association with the screen identification information of the virtual screen 70 displayed on the display surface 521 from the flash memory 13 (S800). The CPU 10 determines whether or not the maximum selection item is in the display areas 71 to 74 of the virtual screen 70 displayed on the display surface 521 (S802). Specifically, the CPU 10 includes the coordinate in the Y direction (see FIG. 4) of the maximum selection item acquired in S800 within the coordinate range in the Y direction of the display areas 71 to 74 displayed on the display surface 521. Determine whether or not.

  When it is determined that the maximum selection item is in the display areas 71 to 74 displayed on the display surface 521 (S802: YES), the CPU 10 corresponds to the up direction keys 60a and 61a and the down direction keys 60b and 61b. The LEDs 66a and 66b are turned on and off with the light emission pattern A (S804), and this process is terminated. Therefore, when the maximum selection item is in the display areas 71 to 74 displayed on the display surface 521, the up direction keys 60a and 61a and the down direction keys 60b and 61b are blinked. Thereby, it can be made to recognize a user easily that the largest selection item exists in the display areas 71-74.

  When it is determined that the maximum selection item is not within the display areas 71 to 74 displayed on the display surface 521 (S802: NO), the CPU 10 has the maximum selection item below the display areas 71 to 74. Whether or not (S806). Specifically, the CPU 10 determines whether the coordinate in the Y direction (see FIG. 4) of the maximum selection item acquired in S800 is larger than the coordinate in the Y direction at the lower end of the display areas 71 to 74 displayed on the display surface 521. Judge whether or not. When it is determined that the maximum selection item is below the display areas 71 to 74 displayed on the display surface 521 (S806: YES), the CPU 10 starts from the lower end of the display areas 71 to 74 to the upper end of the maximum selection item. The distance L is calculated (S808), and the step process proceeds to S812. For example, when the display area 71 displayed on the display surface 521 is the display area 71 shown in FIG. 4 and the maximum selection item is the item J, the distance T1 shown in FIG.

  When it is determined that the maximum selection item is not below the display areas 71 to 74 displayed on the display surface 521 (S806: NO), the CPU 10 starts from the upper end of the display areas 71 to 74 as in S808. A distance L to the lower end of the maximum selection item is calculated (S810).

  The CPU 10 determines whether or not the distance L calculated in S808 or S810 is larger than the first threshold L1 (S812). When the distance L is larger than the first threshold L1 (S812: YES), the CPU 10 sets the LED 66a, 66b corresponding to the direction key 60a, 61a, 60b, 61b in the direction of the maximum selection item for the display areas 71-74 to the light emission pattern C. Is lit (S814), and the process proceeds to S822. For example, when the distance L is the distance T1 shown in FIG. 4, since the distance T1 is larger than the first threshold value L1, the CPU 10 uses the down keys 60b and 61b corresponding to the direction from the display area 71 toward the maximum selection item J. The LED 66b is turned on with the light emission pattern C (see FIG. 6A).

  When the distance L is less than or equal to the first threshold L1 (S812: NO), the CPU 10 determines whether or not the distance L is greater than the second threshold L2 (S816). When it is determined that the distance L is greater than the second threshold L2 (S816: YES), the CPU 10 performs the direction key 60a, 61a, 60b, 61b in the direction of the maximum selection item with respect to the display areas 71 to 74 in the same manner as S814. The LEDs 66a and 66b corresponding to are turned on with the light emission pattern B (S818), and the process proceeds to S822.

  When it is determined that the distance L is equal to or smaller than the second threshold L2 (S816: NO), the CPU 10 applies the direction keys 60a, 61a, 60b, 61b in the direction of the maximum selection item with respect to the display areas 71 to 74 in the same manner as S814. The corresponding LEDs 66a and 66b are turned on with the light emission pattern A (S820).

  CPU10 judges whether the position of the edge part of the display areas 71-74 currently displayed on the display surface 521 and the position of the edge part of the virtual screen 70 are the same (S822). When it is determined that the end portions of the display areas 71 to 74 and the end portion of the virtual screen 70 are in the same position (S822: YES), the CPU 10 ends the present process. The ends of the display areas 71 to 74 and the end of the virtual screen 70 are the ends of the display areas 71 to 74 and the virtual screen 70 in the direction opposite to the direction from the display areas 71 to 74 toward the maximum selection item J. Part. That is, in the case of the display area 72, the end of the display area 72 and the end of the virtual screen 70 are the end in the upward direction opposite to the downward direction from the display area 72 toward the item J, that is, the upper end. Moreover, the case where the edge part of the display areas 71-74 and the edge part of the virtual screen 70 are the same position is a case where the display area 71 of the virtual screen 70 is displayed on the display surface 521, for example.

  When it is determined that the end portions of the display areas 71 to 74 and the end portion of the virtual screen 70 are not at the same position (S822: NO), the CPU 10 corresponds to the up direction keys 60a and 61a and the down direction keys 60b and 61b. Among the LEDs 66a and 66b, an LED different from the LED lit in S814, S818, or S820 is turned on with the light emission pattern A (S824), and this process is terminated.

  Here, the selection item display process shown in FIG. 8 will be described by taking FIG. 4 and FIG. 6 as an example. In the present embodiment, it is assumed that a screen display instruction for displaying the virtual screen 70 illustrated in FIG. 4 is received by a user operation, and the display area 71 of the virtual screen 70 is displayed on the display surface 521 (see S706 illustrated in FIG. 7). . Further, the LEDs 66c corresponding to the cancel keys 60c and 61c, which are valid keys corresponding to the virtual screen 70 shown in FIG. 4, are turned on (see S708 shown in FIG. 7). In addition, the maximum selection item whose number of selections is a predetermined number or more among the items A to J of the virtual screen 70 is set as the item J. In FIG. 6, as in FIG. 5, the display forms of the operation keys 60 a to 61 d by light based on the light emission pattern C are indicated by bold lines for convenience of explanation.

  First, based on the coordinates of the item J, which is the maximum selection item acquired from the coordinate management memory 130, the item J is located below the display area 71 (S806: YES), so that the lower end of the display area 71 extends to the upper end of the item J. The distance T1 is calculated as the distance L (S808). Since the distance T1 is larger than the first threshold L1 (S812: YES), the LEDs 66b of the down direction keys 60b and 61b are turned on with the light emission pattern C (S814). Therefore, as shown in FIG. 6A, the down direction keys 60b and 61b have the shape of the down direction key 61b shown by the transparent regions 611b and 612b of the second transmission film 58, and in the case of the light emission pattern B (for example, The display is clearer than the downward keys 60b and 61b) shown in FIG. Moreover, since the upper end of the display area 71 is the same position as the upper end of the virtual screen 70 (S822: YES), the up direction keys 60a and 61a are not displayed.

  When the selection item display process ends, the step process proceeds to S742 (see FIG. 7). Here, when the down direction keys 60b and 61b are selected by the user (S742: YES, S744: YES), as shown in FIG. 6B, a predetermined amount downward from the display area 71 of the virtual screen 70. The moved display area 72 is displayed on the display surface 521 (S746). Since the item J is below the display area 72 (S806: YES), the distance T2 from the lower end of the display area 72 to the upper end of the item J is calculated (S808). Since the distance T2 is smaller than the first threshold value L1 and larger than the second threshold value L2 (S816: YES), the LEDs 66b of the down direction keys 60b and 61b are turned on with the light emission pattern B (S818). Further, since the upper end of the display area 72 is not at the same position as the upper end of the virtual screen 70 (S822: NO), the LEDs 66a of the up direction keys 60a and 61a are turned on with the light emission pattern A (S824). Therefore, as shown in FIG. 6B, the up direction keys 60a and 61a are displayed in the shape of the up direction key 60a indicated by the transparent area 601a of the first transmission film 56. The downward keys 60b and 61b are displayed in the shape of the downward key 61b indicated by the transparent area 601b of the second transmission film 58.

  When the down key 60b or 61b is selected by the user (S742: YES, S744: YES), as shown in FIG. 6C, the predetermined amount is moved downward from the display area 72 of the virtual screen 70. The displayed area 73 is displayed on the display surface 521 (S746). Since the item J is below the display area 73 (S806: YES), the distance T3 from the lower end of the display area 73 to the upper end of the item J is calculated (S808). Since the distance T3 is smaller than the second threshold L2 (S816: YES), the LEDs 66b of the down direction keys 60b and 61b are turned on with the light emission pattern A (S818). Further, since the upper end of the display area 73 is not at the same position as the upper end of the virtual screen 70 (S822: NO), the LED 66a of the up direction keys 60a and 61a is turned on with the light emission pattern A (S824). Accordingly, as shown in FIG. 6C, the up direction keys 60a and 61a and the down direction keys 60b and 61b are composed of the up direction key 60a and the down direction key 60b indicated by the transparent regions formed on the first transparent film 56. It is displayed in the shape.

  When the down key 60b, 61b is selected by the user (S742: YES, S744: YES), as shown in FIG. 6 (D), a predetermined amount is moved downward from the display area 73 of the virtual screen 70. The displayed area 74 is displayed on the display surface 521 (S746). Since the item J is in the display area 74 (S802: YES), the LEDs 66a, 66b corresponding to the up direction keys 60a, 61a and the down direction keys 60b, 61b are lit in the light emission pattern A (S804). Therefore, as shown in FIG. 6D, the up direction keys 60a and 61a and the down direction keys 60b and 61b are composed of the up direction key 60a and the down direction key 60b indicated by the transparent regions formed on the first transparent film 56. Blinks in the shape of The subsequent processing is the same as the case of the display control processing (see FIG. 7) taking FIG. 4 and FIG.

  As described above, according to the selection item display process, the items A to J included in the virtual screen 70 are displayed on the display surface 521 and the maximum selection item that is the predetermined number or more and has the largest number of selections. The distance L between the display areas 71 to 74 is calculated (see S808 shown in FIG. 8). Then, the light emission patterns D and E of the LEDs 66a to 66d are switched according to the distance L, and the display shapes of the up direction keys 60a and 61a and the down direction keys 60b and 61b are switched (see S812 to S820 shown in FIG. 8). . Therefore, it is possible to easily recognize the distance L from the display areas 71 to 74 displayed on the display surface 521 to the maximum selection item.

  For example, when displaying a list of images stored in the storage medium loaded in the slot unit 80, when a new image is stored in the storage medium, a virtual for displaying a list of images stored in the storage medium is displayed. It is conceivable that the configuration of the screen 70 is changed. In the present embodiment, even when the screen configuration of the virtual screen 70 is changed, various information stored in the coordinate management memory 130 in association with the screen identification information of the virtual screen 70 is updated according to the change. Therefore, display and processing according to the latest screen configuration can always be executed.

  The number of selections of items A to J is stored in the selection number memory 132 in association with each item A to J, and the coordinate information of each item A to J is stored in the coordinate management memory 130 (see FIG. 3). ). By adopting such a configuration, even when the screen configuration of the virtual screen 70 is changed, the number of selections of the items A to J can be continuously measured. Further, the coordinate information of the maximum selection item stored in the flash memory 13 is updated according to the change in the screen configuration of the virtual screen 70. Therefore, even when the screen configuration of the virtual screen 70 is changed, the distance L from the display areas 71 to 74 displayed on the display surface 521 to the maximum selection item in the latest screen configuration is easily recognized. be able to. Therefore, it is possible to further improve user convenience when displaying a virtual screen 70 larger than the display surface 521 of the display 52.

  Further, according to the selection item display processing, the display areas 71 to 74 and the end of the virtual screen 70 in the direction opposite to the direction from the display areas 71 to 74 displayed on the display surface 521 to the maximum selection item are at the same position. Is determined (see S822 shown in FIG. 8). And when the edge part of the display areas 71-74 and the edge part of the virtual screen 70 are not the same position (S822: NO), the direction key corresponding to the direction contrary to the direction which goes to the largest selection item from the display areas 71-74. The LEDs 66a, 66b of 60a, 61a, 60b, 61b are turned on with the light emission pattern A (see S824 shown in FIG. 8). Thereby, it is possible to make the user recognize that the virtual screen 70 extends in the direction opposite to the direction from the display areas 71 to 74 toward the maximum selection item, and it is possible to improve the convenience for the user.

That is, the LEDs 66a to 66d have two light emission patterns having different light colors, and a state of emitting green light is a light emission pattern D, and a state of emitting red light is a light emission pattern E.

  When the LEDs 66a to 66d are lit in the light emission pattern D, the light emitted from the LEDs 66a and 66b does not pass through the upper color separation region 650a and the lower color separation region 650b. For this reason, from the front surface side of the touch panel 54, the user presses the up key 61a and the down key 61b (shown in FIG. 5B) displayed in green and indicated by the first upper transparent region 611a and the first lower transparent region 611b. The same shape as the upward keys 60a and 61a shown) is visually recognized.

  When the LEDs 66a to 66d are lit in the light emission pattern E, the light emitted from the LEDs 66a and 66b passes through the upper color separation region 650a and the lower color separation region 650b. For this reason, the user displays the first upper transparent area 611a and the upper color separation area 650a, and the first lower transparent area 611b and the lower color separation area 650b displayed in red from the front surface side of the touch panel 54. The key 61a and the downward key 61b (the downward key 61b shown in FIGS. 5A and 5B) are visually recognized.

<Electrical configuration>
An electrical configuration of the MFP 1 according to the second embodiment will be described. Since the MFP 1 according to the second embodiment has the same electrical configuration as that of the first embodiment (see FIG. 3) except for the luminance memory 112, the description of the configuration other than the luminance memory 112 is omitted.

  The luminance memory 112 is a memory area for storing the two light emission patterns D and E in the LEDs 66a to 66d and the light emission colors of the LEDs 66a to 66d corresponding to the light emission patterns D and E in association with each other.

<Operation of Embodiment>
The operation of the MFP 1 according to the second embodiment will be described with reference to FIGS.

(Display control processing)
A display control process executed by the CPU 10 of the MFP 1 will be described. Since most of the display control process in the second embodiment performs the same process as the display control process in the first embodiment, it will be described with reference to the flowchart of FIG. 7 showing the display control process in the first embodiment.

  Since step processes S700 to S716 are the same as those in the first embodiment, the description thereof is omitted. When it is determined that the distance Lu calculated in S714 is greater than the first threshold L1 (S716: YES), the CPU 10 lights the LED 66a corresponding to the up key 61a with the light emission pattern E, that is, emits red light (S718). ), The process proceeds to S728.

  When it is determined that the distance Lu is equal to or smaller than the first threshold L1 (S716: NO), the CPU 10 skips step S720 and S722 and determines whether the distance Lu is 0 (S722). When it is determined that the distance Lu is 0 (S724: YES), the CPU 10 shifts the step process to S728. When it is determined that the distance Lu is 0 (S724: YES), the CPU 10 lights the LED 66a corresponding to the up key 61a with the light emission pattern D, that is, emits green light (S718), and the step process proceeds to S728. To do. Since step processes S728 to S730 are the same as those in the first embodiment, the description thereof is omitted.

  If it is determined that the distance Ld calculated in S728 is larger than the first threshold L1 (S730: YES), the CPU 10 lights the LED 66b corresponding to the down key 61b with the light emission pattern E (S732), and step The process proceeds to S742.

  When it is determined that the distance Ld is equal to or less than the first threshold L1 (S730: NO), the CPU 10 skips step S734 and S736 and determines whether the distance Ld is 0 (S738). When it is determined that the distance Lu is 0 (S738: YES), the CPU 10 shifts the step process to S742. When it is determined that the distance Ld is 0 (S738: YES), the CPU 10 turns on the LED 66b corresponding to the down key 61b with the light emission pattern D (S740), and proceeds to step S742. Since step processes S742 to S756 are the same processes as those in the first embodiment, description thereof will be omitted.

(Selected item display processing)
Next, the selection item display process (S712) executed by the CPU 10 of the MFP 1 will be described. Since most of the selection item display processing in the second embodiment performs the same processing as the selection item display processing in the first embodiment, refer to the flowchart of FIG. 8 showing the selection item display processing in the first embodiment. explain.

  Since step processes S800 to S802 are the same as those in the first embodiment, the description thereof is omitted. As a result of the determination in S802, when it is determined that the maximum selection item is in the display areas 71 to 74 displayed on the display surface 521 (S802: YES), the CPU 10 corresponds to the two direction keys 61a and 61b. The LEDs 66a and 66b to be turned on and blink with the light emission pattern D (S804), and this process is terminated. Therefore, when the maximum selection item is in the display areas 71 to 74 displayed on the display surface 521, the up direction key 61a and the down direction key 61b are blinked and displayed in green (see FIG. 6D).

  Steps S806 to S812 are the same as those in the first embodiment, and thus the description thereof is omitted. As a result of the determination in S812, when the distance L calculated in S808 or S810 is larger than the first threshold L1 (S812: YES), the CPU 10 uses the direction keys 61a and 61b in the direction of the maximum selection item for the display areas 71 to 74. The corresponding LEDs 66a and 66b are turned on with the light emission pattern E (S814), and the process proceeds to S822. For example, as shown in FIG. 4, a case where the maximum selection item is item J and the distance L is the distance T1 is considered. In this case, since the distance T1 is larger than the first threshold value L1, the CPU 10 lights the LED 66b of the down key 61b corresponding to the direction from the display area 71 toward the maximum selection item J with the light emission pattern E. Therefore, as shown in FIG. 6A, the down key 61b is displayed in red in the shape indicated by the first lower transparent area 611b and the lower color separation area 650b.

  The CPU 10 skips Steps S816 to S818, and turns on the LEDs 66a and 66b corresponding to the direction keys 61a and 61b in the direction of the maximum selection item for the display areas 71 to 74 with the light emission pattern D in S820. For example, as shown in FIG. 4, a case where the maximum selection item is item J and the distance L is the distance T3 is considered. In this case, since the distance T3 is less than the first threshold value L1, the CPU 10 turns on the LED 66b of the down key 61b corresponding to the direction from the display area 73 toward the maximum selection item J with the light emission pattern D. Accordingly, as shown in FIG. 6C, the down key 61b is displayed in green in the shape indicated by the first lower transparent region 611b.

  Step process S822 is the same process as in the first embodiment, and a description thereof will be omitted. As a result of the determination in S822, when it is determined that the position of the end of the display areas 71 to 74 displayed on the display surface 521 is not the same as the position of the end of the virtual screen 70 (S822: NO), the CPU 10 Of the LEDs 66a and 66b corresponding to the up direction key 61a and the down direction key 61b, an LED different from the LED lit in S814, S818, or S820 is lit with the light emission pattern D (S824), and the process is terminated. For example, as shown in FIG. 4, consider a case where the maximum selection item is item J and the display area 73 is displayed on the display surface 521. In such a case, since the upper end of the display area 73 and the upper end of the virtual screen 70 are not at the same position, the CPU 10 lights the LED 66a of the up key 61a opposite to the direction from the display area 73 toward the maximum selection item J with the light emission pattern D. . Therefore, as shown in FIG. 6C, the up direction key 61a is displayed in green in the shape indicated by the first upper transparent region 611a.

  In this embodiment, the same effect as that of the first embodiment can be obtained. Further, the up direction key 61a and the down direction key 61b in the present embodiment are configured by a first upper transparent area 611a and a first lower transparent area 611b, and an upper color separation area 650a and a lower color separation area 650b, respectively. The first upper transparent region 611a and the first lower transparent region 611b, and the upper color separation region 650a and the lower color separation region 650b have different wavelength regions of light that can be transmitted. Moreover, LED66a-66d has two or more light emission patterns from which the color of light differs.

  Therefore, the up direction key 61a displays the first upper transparent area 611a and the upper color separation area 650a according to the color of light (see FIG. 5C) and the first upper transparent area 611a. The shape to be changed (see FIG. 5B) is switched. Similarly, the down key 61b has a shape (see FIG. 5B) in which the first lower transparent area 611b and the lower color separation area 650b are displayed according to the color of light, and the first lower transparent area 611b The displayed shape (see FIG. 5C) is switched.

  The shape in which the first upper transparent area 611a and the upper color separation area 650a are displayed, and the shape in which the first lower transparent area 611b and the lower color separation area 650b are displayed are changed to red by light based on the light emission pattern E. Is displayed. In addition, the shape in which the first upper transparent region 611a is displayed and the shape in which the first lower transparent region 611b is displayed are displayed in green by light based on the light emission pattern D. Therefore, the colors of the up key 61 a and the down key 61 b are also switched according to the distance L between the end of the virtual screen 70 and the display areas 71 to 74 displayed on the display surface 521. Therefore, the user can easily recognize the distance from the display areas 71 to 74 displayed on the display surface 521 to the edge of the virtual screen 70 by confirming the display of the up key 61 a and the down key 61 b. be able to.

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various aspect can be taken in the range which does not deviate from the summary of this invention.

  In the present embodiment, the MFP 1 has been described as an example of the information processing apparatus of the present invention. However, the present invention is not limited to this, and various modes can be adopted as long as the touch panel display unit 50 is provided as in the above embodiment.

  In the present embodiment, the touch panel display unit 50 is configured by directly overlapping the touch panel 54 on the transmissive films 56 and 58 (see FIGS. 2 and 9). However, the present invention is not limited to this, and a smoke film may be provided between the transmissive films 56 and 58 and the touch panel 54. The smoke film is a dark gray film having a low visible light transmittance (for example, 40%), and only a region facing the display 52 is formed to be transparent. When the LEDs 66a to 66d are turned off, the user can hardly visually recognize the operation keys 60a to 61d from the surface side of the touch panel 54 due to the presence of the smoke film. Thereby, the erroneous operation of the operation keys 66a to 66d by the user can be reduced more reliably.

  In the first embodiment, the first transmission film 56 has a higher visible light transmittance than the second transmission film 58. However, if the light based on the light emission patterns B and C is transmitted to the extent that the user can see from the surface side of the touch panel 54, the visible light transmittance of the first transmission film 56 and the second transmission film 58 is the same. Good.

  In the present embodiment, the second transmission film 58 is a film having a very low visible light transmittance (for example, 0.1%), but has a visible light transmittance of 0%, that is, completely transmits light. It may be a film that does not.

  Moreover, in 1st Embodiment, the touchscreen display part 50 was comprised by the 1st transparent film 56 and the 2nd transparent film from which the area | region formed transparently differed.

  In the present embodiment, the up direction keys 60a and 61a and the down direction keys 60b and 61b are formed in arrow shapes indicating the respective directions. However, the present invention is not limited to this, and the directions corresponding to the operation keys. Various forms can be adopted as long as it is visible. For example, similarly to the cancel keys 60c and 61c and the OK keys 60d and 61d, an image in which characters or figures indicating upward and downward directions are written in a rectangular frame may be formed.

  Further, in the present embodiment, the virtual screen 70 (see FIG. 4) that is longer in the vertical direction than the display surface 521 of the display 52 has been described as an example. A case where a long virtual screen 70 is displayed is also conceivable. In this case, in addition to the upward keys 60a and 61a and the downward keys 60b and 61b shown in the present embodiment, the display areas 71 to 74 displayed on the display surface 521 of the virtual screen 70 are moved to the right and left. It is preferable that a right direction key and a left direction key are provided.

  In the first embodiment, the second upper region 602a and the second lower region 602b are provided in the first transmission film 56 at positions facing the second upper transparent region 612a and the second lower transparent region 612b of the second transmission film 58.

Accordingly, the lengths of the arrows indicating the up direction keys 60a and 61a and the down direction keys 60b and 61b are changed according to the switching of the light emission pattern. However, the present invention is not limited to this, and various forms can be adopted as long as the shape of the arrow can be changed according to switching of the light emission pattern. For example, the thicknesses of the arrows indicating the up direction keys 60a and 61a and the down direction keys 60b and 61b may be changed according to switching of the light emission pattern. In such a case, the second upper transparent region 612a and the second lower transparent region 612b or the upper color separation region 650a and the lower region are arranged on the outer peripheral regions of the first upper transparent region 611a and the first lower transparent region 611b in the second transmissive film 58. A color separation region 650b may be provided.
