When the display control means 262 of the display device 2 receives the image data via the communication unit 28, the display control unit 262 adds a record in which the image data is recorded as display data to the display object management table 271, and the display unit 22 with a touch sensor. As a display object.

  Further, when the information processing device 4 transmits the document data designated in accordance with the operator's designated operation to the display device 2, the display control means 262 of the display device 2 records a record in which the document data is recorded as display data. While adding to the display object management table 271, it displays as a display object on the display part 22 with a touch sensor.

  FIG. 4A (a) is a diagram illustrating an example of a display screen displayed on the display unit with a touch sensor. On the display screen of the display unit 22 with a touch sensor, a plurality of display objects 10A to 10H are displayed based on the image data or document data received as described above. The display objects 10A to 10H are displayed as an initial position, for example, in order from the lower left. Thereafter, when the operation receiving unit 260 receives a moving operation such as drag and drop for the display objects 10A to 10H via the touch sensor 221, the display control unit 262 updates the normal position information according to the moving operation. Change the display position.

(2) Display Object Attraction Processing Display object display processing in the display device 2 will be described with reference to the flowchart of FIG. Here, a case will be described in which an operator present on the right side of the table unit 20 performs a pressing operation on the first pulling switch 24A.

  First, the operation accepting means 260 accepts a change instruction from the first pulling switch 24A in response to the pressing operation by the operator (S1).

  Next, the position calculation unit 261A selects one of the display objects according to the position where the drawing switch that receives the change instruction is arranged so as to sequentially process the display objects in the display object management table 271. (S10).

  Here, since the first attraction switch 24A has been pressed, the position calculation unit 261A selects display objects in the order in which they are displayed on the right side in the display unit 22 with a touch sensor, that is, in the descending order of the X coordinates in the normal position information. To do. Here, the display object selected by the position calculating unit 261A is referred to as a selected object.

  Next, the position calculating means 261A determines whether or not there is a blank area on the first pulling switch 24A side (S20). Specifically, the position calculation unit 261A refers to the display object management table 271 and determines whether or not the selected object can be moved to the right without overlapping the display area occupied by other display objects.

  When the position calculation unit 261A determines that there is a blank area on the first pulling switch 24A side (S20: Yes), the position calculating unit 261A calculates pulling position information obtained by shifting the X coordinate of the selected object in the plus direction. The information is recorded in the drawing position information of the display object management table 271 (S21).

  Next, the display control means 262 changes the display position of the selected object based on the calculated drawing position information (S30).

  Then, the display control means 262 determines whether or not the display positions of all the display objects have been changed (S40). If it is determined that the display positions of all the display objects have not been changed (S40: No). ), The process returns to step S10, and the next display object is selected (S10). On the other hand, when the display control means 262 determines that the display positions of all the display objects have been changed (S40: Yes), the series of pulling processing ends.

FIG. 4A (b) is a diagram showing an example of a display screen in which the display object is changed to the drawing switch side. The display objects 10A _{1 to} 10H ₁ are displayed at display positions where the X coordinate is shifted in the plus direction compared to the display position of FIG. 4A (a). The first attracted switch 24A ₁ is turned on by the operator of the pressing operation. By shifting the X coordinate in the plus direction, the Y coordinate between the display objects does not change, so that the positional relationship between the display objects before and after the change is maintained.

  Then, the display control unit 262 changes the display position of the display object recorded as “no pinning” in the display object management table 271 to the display position based on the normal position information.

FIG. 4B (d) is a diagram illustrating an example of a display screen in which a display object that is not pinned is returned to a normal position. The display objects 10A, 10C to 10H that have not been instructed to be selected are displayed at the same display position as that in FIG. 4A (a), that is, the normal position before changing to the drawing position. On the other hand, the display object 10B ₂ that is the selection instruction, the position similar to that of FIG. 4B (c), i.e., is displayed in the drawn position.

(5) Display processing of writing object When the operator performs a writing operation of writing a memo or the like with the touch pen 23 on the display unit 22 with the touch sensor, the touch sensor 221 uses the handwriting by the writing operation as writing data. To detect.

  The display control unit 262 displays a writing object based on the writing data detected by the touch sensor 221 on the display unit 220.

  Moreover, the writing data management means 263 specifies the display object to which the writing data is written from the position where the writing data is written. Then, the writing data management unit 263 records the object ID indicating the specified display object as the writing object ID, and adds the record in which the writing data is recorded to the writing object management table 272.

FIG. 4C (e) is a diagram illustrating an example of a display screen on which a writing object is displayed. The display object 10B ₂ that the writing operation is, writing the object 102 is displayed, which is written by the touch pen 23.

  Next, when the operation receiving unit 260 receives a selection release instruction including the pinning release position information on which the touch operation has been performed from the touch sensor 221, the display control unit 262 releases the pinning release received by the operation receiving unit 260. A display object corresponding to the position information is specified.

  Then, the display control unit 262 hides the pinning mark 101 for the specified display object, and changes the display position of the specified display object to a display position based on the normal position information. At that time, if there is a record in which the display object is recorded as the writing object ID in the writing object management table 272, the display control means 262 similarly changes the display position of the writing object corresponding to the record. .

  Further, the display control unit 262 records “no pinning” in the display object management table 271 as the presence / absence of pinning of the record corresponding to the specified display object.

FIG. 4C (f) is a diagram illustrating an example of a display screen in which the display object whose pinning has been released is returned to the normal position. When deselected instruction to the display object 10B ₂ that pinned is is, the display object 10B, the display position similar to FIG. 4A (a), i.e., is displayed in the normal position. Further, the writing object 112 associated with the display object 10B is moved along with the change in the display position of the display object 10B.

(Modification of the attraction release process)
