  FIG. 3 is a flowchart showing the association process according to the first embodiment of the present invention. FIG. 4 is a flowchart showing a subroutine of the registration process (1) according to the first embodiment. FIG. 5 is a plan view of the display device 1 showing a form in which a desired keyboard 15 is associated with a file. Unless otherwise specified, the control entity of this flow is the CPU 6. For example, this flow starts under the condition that the main power source (not shown) of the display device 1 is turned on from off. After starting this flow, the process proceeds to step a1, and the sensor 3 senses the state on the screen as the display unit of the display device 1 in order to determine whether or not there is an object in the next process. Next, the process proceeds to step a2, and it is determined whether or not there is an object on the screen. That is, as a result of the sensing, if it is determined that there is an object on the screen, the process proceeds to the next step a3, and if it is determined that there is no object on the screen, this process is terminated.

  In step a3, the position of the object is recognized by the position recognition process described above. Next, the process proceeds to step a4, and it is determined whether or not the object is present at or near the image (target file) position displayed on the display unit. When it is determined that there is an object at or near the file display position, the process proceeds to the next step a5, and when it is determined that there is no object at or near the file display position, this process is terminated. In step a5, the “registration” selection menu screen 16 is displayed near the object on the screen (see FIG. 5). Next, the process proceeds to step a6, and it is determined whether or not “registration” is selected on the “registration” selection menu screen 16. When “Register” is selected, the process proceeds to the next step a7, and when it is not selected, this process is terminated.

  In step a7, the process proceeds to a registration process subroutine which will be described later. Next, the process proceeds to step a8, where it is determined whether or not the registration work has been completed for all the files to be registered. When the registration work has been completed for all the files to be registered, this process ends. If it is determined that the registration work for any file that is desired to be registered has not been completed, the process returns to step a5.

  The registration process shown in FIG. 4 starts under the condition for shifting to step a7. After the start of the registration process, the process proceeds to step a70 to select a file to be registered. Next, the process proceeds to step a71, and it is determined whether or not the object placed on the screen is the keyboard 15 by keyboard identification processing. For example, keyboard identification processing can be executed by using at least one of a specific shape, a mark, a barcode, a watermark, a tag, and a shape as identification information given to each keyboard 15.

  Next, the process proceeds to step a72, where it is determined whether or not the object on the screen is the keyboard 15. If it is determined that the object is the keyboard 15 that is desired to be registered, the keyboard 15 is associated with the file by the link generation process described above (step a73). Thereafter, the main registration process is terminated. If the object is not identified as the keyboard 15 (step a72: NO), the registration process is terminated. In this embodiment, when the object is not determined as the keyboard 15, the main registration process ends. For example, the object shape is recognized by the shape recognition process described above, and the object shape and the file are determined by the link generation process. Association may be performed. According to the association processing shown in FIGS. 3 to 5 described above, the target file can be edited by the associated keyboard 15.

  FIG. 6 is a flowchart showing the association process according to the second embodiment of the present invention. FIG. 7 is a flowchart showing a subroutine of the registration process (2) according to the second embodiment. FIG. 8 is a plan view of the display device 1 showing a form in which the keyboard 15 is placed in the registration area At and the keyboard 15 is associated with a file. FIG. 9 is a plan view of the display device 1 showing a form in which a desired file is associated with the keyboard 15. Unless otherwise specified, the control entity of this flow is the CPU 6. For example, this flow starts under the condition that the main power supply of the display device 1 is turned on. After the start of this flow, the process proceeds to step b1, and the “registration” selection menu screen 16 is displayed on the screen. Next, the process proceeds to step b 2, where it is determined whether or not “registration” is selected on the “registration” selection menu screen 16. When "Register" is selected, the process proceeds to the next step b3, and the state on the screen as the display unit is sensed by the sensor 3. Next, the process proceeds to step b4, where the position of the object is recognized by the position recognition process described above.

  Next, the process proceeds to step b5, and it is determined whether or not the object is in a predetermined place, in other words, in a predetermined registration area At. When it is determined that the object is in the registration area At, the process proceeds to the next step b6, and when it is determined that the object is not in the registration area At, the process is terminated. In step b6, the process proceeds to a registration process subroutine which will be described later. Next, the process proceeds to step b7, and it is determined whether or not registration is completed. If it is determined that the registration has been completed, the process is terminated. If it is determined that the registration has not ended, the process returns to step b1.

  The registration process shown in FIG. 7 is executed under the condition for shifting to step b6. After the start of the main registration process, the process proceeds to step b60, and it is determined whether or not the object in the predetermined place so-called registration area At is the keyboard 15 by the keyboard identification process. Keyboard identification processing can be executed by at least one of a specific shape, a mark, a QR code, a barcode, a watermark, a tag, and a shape as identification information given to each keyboard 15. Next, the process proceeds to step b61, where it is determined whether or not the object on the screen is the keyboard 15.

  If it is determined that the object is the keyboard 15 that is desired to be registered, the keyboard 15 is associated with the file by the link generation process described above (step b62). Thereafter, the main registration process is terminated. If the object is not identified as the keyboard 15 (step b61: No), the registration process is terminated. In this embodiment, when the object is not determined as the keyboard 15, the main registration process ends. For example, the object shape is recognized by the shape recognition process described above, and the object shape and the file are determined by the link generation process. Association may be performed. According to the association process shown in FIGS. 6 to 8 described above, the target file can be edited by the associated keyboard 15.

  FIG. 10 is a flowchart showing processing for displaying information associated with the keyboard 15 when the keyboard 15 is placed according to the third embodiment of the present invention. FIG. 11 is a plan view of the display device 1 showing a form for displaying a file associated with the keyboard 15. Unless otherwise specified, the control entity of this flow is the CPU 6. For example, this flow starts under the condition that the main power supply of the display device 1 is turned on. After starting this flow, the process proceeds to step c1, and the state on the screen is sensed by the sensor 3 in order to determine whether or not there is an object in the next process. Next, the process proceeds to step c2, and it is determined whether or not there is an object on the screen. That is, if it is determined that there is an object on the screen as a result of the sensing, the process proceeds to the next step c3, and if it is determined that there is no object on the screen, this process is terminated.

  In step c3, the position of the object is recognized by the position recognition process described above. Next, the process proceeds to step c4, where it is determined whether or not the object placed on the screen is the keyboard 15 by keyboard identification processing. For example, keyboard identification processing can be executed by using at least one of a specific shape, a mark, a QR code, a barcode, a watermark, a tag, and a shape as identification information given to each keyboard 15. Next, the process proceeds to step c5, where a file associated with the keyboard 15 is searched by the information search process described above. In the next step c6, if it is determined that there is a file associated with the keyboard 15, the process proceeds to the next step c7 to display the associated file on the screen. Thereafter, this process is terminated. If it is determined in step c6 that there is no associated file (step c6: No), this process ends.

  FIG. 12 is a flowchart showing a process of removing information associated with the keyboard 15 when the keyboard 15 is removed. After starting this flow, the process proceeds to step d1, and it is monitored whether the keyboard is removed from the screen. If it is determined that it has been removed, the process proceeds to the next step d3. If it is determined that it has not been removed, the process returns to the start of this flow. In step d3, an inquiry process is performed as to whether or not to hide the associated file. At this stage, for example, when “non-display” is accepted or selected by the user, the signal is sequentially transmitted to the CPU via the sensor, the sensor input unit, and the bus. If it is confirmed that the CPU is not displayed, the process proceeds to step d4 to hide the associated file. Thereafter, this process is terminated. If “non-display” is unapproved in step d3 (step d3: NO), this process is terminated.

  FIG. 13 is a flowchart showing a process of associating a file with any one of a plurality of keyboards and releasing the association between the other keyboard and the file. FIG. 14 is a plan view of the display device 1 showing the relationship between one file and a plurality of keyboards 15, and FIG. 14A is a plan view of the display device 1 showing a state before any of the keyboards 15 is associated. FIG. 14 and FIG. 14B are plan views of the display device 1 showing the state after the keyboard 15 is associated. FIG. 15 is a plan view of the display device 1 showing the relationship between one keyboard 15 and a plurality of files, and FIG. 15A is a plan view of the display device 1 showing a state before any file is associated, FIG. 15B is a plan view of the display device 1 showing a state after the files are associated with each other.

  In step c7, the associated file is displayed on the screen, and then the process proceeds to step c8. Here, it is determined whether or not the file displayed on the screen is a file (so-called shared file) associated with a plurality of keyboards 15. If it is determined that the file is a shared file, the process proceeds to step c9 to determine whether any one of the plurality of keyboards 15 is selected. At this time, as shown in FIG. 14A, a message image such as “Which keyboard should be selected?” Is displayed on the screen, and the keyboard 15 is selected by the flushing FL.

  When the keyboard 15 to be associated with the file is selected, the process proceeds to step c10, where the selected keyboard 15 is associated with the file, and the association between the other keyboard 15 and the file is released. As shown in FIG. 14B, the file display is controlled so that the direction and position of the file change according to the selected keyboard 15 (P1). Thereafter, this process is terminated. If it is determined in step c8 that the file is not a shared file, this process is terminated. If it is determined in step c9 that the keyboard 15 to be associated with the file has not been selected, the process returns to step c9 again. The program including step c9 corresponds to selection means.

  As shown in FIG. 15A, when there are a plurality of files associated with one keyboard 15, a message image 17 such as “Which file do you want to edit?” Is displayed on the screen, and flushing is performed. The file is selected by FL. As shown in FIG. 15B, the orientation and position of the selected file (for example, File C) are displayed in accordance with the keyboard 15. Unselected files (for example, File A and B) are cleared at the corner (one place) of the screen. Therefore, the workability of the selected file can be improved.

  FIG. 16 is a diagram showing a form of a keyboard 15A to which device identification information 18 is attached and which can notify on / off of each button switch. FIG. 16 (a) is a front view of the keyboard 15A, and FIG. 16 (b). These are rear views of the keyboard 15A. The keyboard 15A as an input device is connected to the CPU 6 via the peripheral device input unit 8 and the bus 13 to turn on / off each button switch assigned to each operation key (corresponding to key identification information) wirelessly or by wire. Notice. On the back surface of the keyboard 15A, as shown in FIG. 16B, at least one of a specific shape, mark, QR code, bar code, and embedded tag for identifying the keyboard 15A (corresponding to device identification information) ) Is provided.

  FIG. 17 is a diagram showing a form in which the device identification information 18 is given and the keyboard is displayed on the screen. FIG. 17A is a front view of the keyboard 15B, and FIG. 17B is a rear view of the keyboard 15B. is there. On the back surface of the keyboard 15B as an input device, at least one of a specific shape, a mark, a QR code, a barcode, a tag, and a watermark (corresponding to device identification information) is provided. By placing such a keyboard 15B on the screen, the CPU 6 may separately display a software keyboard on the screen. In this case, the shape of the keyboard 15B can be simplified, and the structure of the input device itself can be simplified.

  18A and 18B are diagrams illustrating a form in which device identification information is given and whether or not an input is made by pressing each button. FIG. 18A is a front view of the keyboard 15C, and FIG. 18B is a keyboard 15C. FIG. On the back surface of the keyboard 15C as an input device, at least one of a specific shape, a mark, a QR code, a bar code, a tag, a watermark, and the like (corresponding to device identification information) is provided. The keyboard 15C may have a structure in which a key is input by touching a bar code or the like on the panel surface by a transparent board or button press 19.

  FIG. 19 is a diagram illustrating an example in which an association table is held. File A, file B, and file C are associated with the keyboard (1). A file D is associated with the keyboard (2). The file A, file B, file C, and file D may be displayed on the screen at the timing when the keyboards (1) and (2) are placed on the screen of the display device 1. File A, file B, file C, and file D may be hidden on the screen at the timing when the keyboards (1) and (2) are removed from the screen of the display device.

  FIG. 20 is a diagram illustrating an example in which an association table is created each time. The file A is displayed on the screen of the display device 1 and no keyboard is placed on the screen. From this state, the keyboard (1) is placed on the file A, in the vicinity of the file A or in the registration area. Then, the file A and the keyboard (1) are associated with each other. Thereafter, when the keyboard (1) is removed from the screen, the association between the file A and the keyboard (1) is deleted. The file A may be hidden at the timing when the keyboard (1) is removed from the screen.

  According to the display device 1 described above, the CPU 6 as the control means recognizes the position of the keyboard 15 and then makes a relative relationship with the position of the file displayed on the screen (steps a4 and FIG. 6 in FIG. 3). Based on step b5), it is determined whether or not the file can be rewritten / updated by the keyboard 15. As in the prior art, the trouble of electrically and mechanically connecting the input device with a cable or the like can be omitted. Thus, the keyboard 15 as the input device can be easily associated with the file stored in advance in the main storage unit 10 and the like, and the operability can be improved. Therefore, according to the present display device 1, it is not necessary to use a cable or the like, and the time required for the association can be reduced.

  The sensor 3 and the built-in camera 4 detect whether or not the keyboard 15 as an object is placed on the screen. The CPU 6 can recognize the position of the keyboard 15 based on the detection result.

  According to the control method of the present embodiment, whether or not to associate the file with the keyboard 15 based on the relative relationship between the step of recognizing the position of the keyboard 15 and the position of the file displayed on the screen. And determining whether or not. By these steps, the file and the keyboard 15 are associated with each other. In other words, the file can be rewritten and updated by the keyboard 15. In this way, the keyboard 15 and the file can be easily associated with each other, and the operability can be improved. Therefore, according to the present control method, it is possible to reduce the time required for the association without having to use cables and the like.

  According to the display device 1 described above, the CPU 6 as the control unit determines whether or not the keyboard 15 is placed on the screen. When determining that the keyboard 15 is placed, the CPU 6 displays a file associated with the keyboard 15 on the screen. As described above, the file can be displayed on the screen, and the file can be rewritten / updated by a simple operation by simply placing the keyboard 15. As in the prior art, the trouble of electrically and mechanically connecting the keyboard with a cable or the like can be eliminated. Therefore, according to the display device 1 according to the present embodiment, file input / output can be executed easily and without delay.

  Since the CPU 6 displays a plurality of files respectively associated with the plurality of keyboards 15 on the screen, the versatility for the plurality of keyboards 15 can be enhanced. Moreover, it is possible to rewrite / update a plurality of files in parallel by using the plurality of keyboards 15. Thus, the convenience of the display device 1 can be improved.

  When a file is associated with a plurality of keyboards 15, as shown in step c10 of FIG. 13 and the like, the file is associated with one keyboard 15 and the association between the other keyboard 15 and the file is released. Thereafter, only the file associated with one keyboard 15 can be rewritten / updated. So-called sharing violations can be avoided.

  The CPU 6 corrects the display position of the file image displayed based on the file associated with one keyboard 15 based on the position of the keyboard 15. As shown in FIG. 14B and the like, the CPU 6 corrects the file associated with the keyboard 15 in the direction of the selected keyboard 15 so as to be rotated around the axis direction perpendicular to the screen. That is, since the file image can be displayed near the keyboard without any operation by the user, the image can be easily viewed, and the operability of the keyboard 15 can be improved.

  The keyboard 15 serving as the input device described above includes device identification information specific to the keyboard 15 placed on the screen and each operation for determining whether or not each operation key of the keyboard 15 is operated. Key identification information unique to the key is provided. Even when a plurality of keyboards 15 are used, the desired keyboard 15 can be easily and reliably identified by the keyboard 15 to which device identification information is assigned. In other words, a plurality of keyboards 15 can be used in parallel. Further, since the key identification information described above is given to the keyboard 15, it is possible to realize rewriting / updating of information via each operation key.

  The CPU 6 as the control means recognizes input from the keyboard 15 by scanning device identification information unique to the keyboard provided for each keyboard 15. Even when a plurality of keyboards 15 are used, the display device 1 that can easily and reliably identify a desired keyboard 15 can be realized. In other words, the display device 1 that can be used in parallel can be realized in other words.

  In the present embodiment, a keyboard is applied as an input device, but is not limited to a keyboard. For example, a pointing device or the like may be applied as the input device. Even in this case, the same effects as in the present embodiment can be obtained. In addition, the present invention can be implemented in various forms without departing from the spirit of the present invention.
