FIGS. 4 and 5 are flowcharts showing the procedure of processing by the electronic white board device 1 of the first embodiment, and FIGS. 6 to 8 are schematic views showing examples of display screens by the electronic white board device 1 of the first embodiment. .
The control unit 10 of the electronic white plate device 1 determines by the touch panel control unit 13 whether or not the input operation is performed on the touch panel 13a, and when it is determined that the input operation is performed, display is performed in the menu area 1b. It is determined whether or not the selection operation for the pen menu M1 has been performed (S1). Specifically, the touch panel control unit 13 calculates the operation position by the operating tool with respect to the surface of the touch panel 13a, and the control unit 10 calculates the operation position calculated by the touch panel control unit 13 within the display area of the pen menu M1. It is determined whether or not

  If it is determined that the selection operation for pen menu M1 has been performed (S1: YES), control unit 10 is in a state of waiting for handwriting input for drawing area 1a, and determines whether or not handwriting input is performed for drawing area 1a. (S2). If it is determined that handwriting input has been made (S2: YES), that is, if the user has drawn characters or pictures in the drawing area 1a with the operating body, the control unit 10 displays the information (handwriting information) input by handwriting. The control unit 12 displays on the display panel 12a (S3). Specifically, the control unit 10 causes the display control unit 12 to plot the position corresponding to the operation position calculated by the touch panel control unit 13 on the display panel 12 a.

  After the process of step S3, or when it is determined that the handwriting is not input in step S2 (S2: NO), the control unit 10 performs any of the menus displayed in the menu area 1b by the input operation on the touch panel 13a. It is determined whether or not the selection operation has been performed on the subject (S4). Specifically, the touch panel control unit 13 calculates the operation position by the operating tool with respect to the surface of the touch panel 13a, and the control unit 10 determines whether the operation position calculated by the touch panel control unit 13 is within the menu area 1b. Decide whether or not.

When it is determined that the selection operation for any of the menus is not performed (S4: NO), the control unit 10 returns to the process of step S2, and is handwritten input each time handwriting input is performed to the drawing area 1a. The information is sequentially displayed on the display panel 12a.
If it is determined that a selection operation has been performed on any of the menus (S4: YES), the control unit 10 returns to the process of step S1.

  When it is determined that the selection operation for the pen menu M1 is not performed (S1: NO), the control unit 10 determines whether the selection operation for any of the material display menus M2 to M7 is performed (S5) . Specifically, control unit 10 selects or operates one of scale feed menu M2 displayed in menu area 1b, triangle ruler menu M3, protractor menu M4, mandarin menu M5, apple menu M6, or abacus menu M7. To judge. The control unit 10 operates as a selection receiving unit that receives selection of any of a plurality of material images (material image data) via the material display menus M2 to M7.

  If it is determined that a selection operation has been performed on any of the material display menus M2 to M7 (S5: YES), the control unit 10 waits for a touch operation (input operation) on the drawing area 1a of the touch panel 13a. The touch panel control unit 13 determines whether the touch operation has been performed on the touch panel 1a (S6). The user designates the position where the selected material image is to be displayed by a touch operation on the drawing area 1a. Therefore, when it is determined that the touch operation is performed on the drawing area 1a (S6: YES), the control unit 10 corresponds to the material display menu M2 to M7 selected and operated at the position where the touch operation is performed on the display panel 12a. The material image to be displayed is displayed by the display control unit 12 (S7). Each material image data for displaying each material image on the display panel 12 a is, for example, included in the display control application, and is stored in the storage unit (data storage unit) 11. Therefore, the control unit 10 reads the material image data corresponding to the selected material display menu M2 to M7 from the storage unit 11 and sends it to the display control unit 12, and the display control unit 12 is based on the acquired material image data. The source image is displayed on the display panel 12a. At this time, the control unit 10 instructs the display control unit 12 to display the material image at the position (operation position) where the touch operation is performed on the drawing area 1a, and thereby, the instruction by the touch operation by the user The material image is displayed at the displayed position.

FIG. 6A shows an example of a display screen when the rule menu M2 is selected. As shown in FIG. 6A, when touch operation is performed on the drawing area 1a using the operation tool (the touch pen P in FIG. 6A) after the selection menu M2 is selected, the image of the ruler at the operation position touched (touch operation) Material image is displayed. In the example shown in FIG. 6A, the image of the ruler is displayed with the operation position at the center, but the image (material image) of the ruler may be displayed with the operation position as the left end or the right end.
In addition, even when one of the triangle ruler menu M3, the protractor menu M4, the mandarin menu M5, the apple menu M6, and the abacus menu M7 is selected and operated, the operation position at which the drawing area 1a is touch-operated is subsequently performed. An image of a triangle, protractor, orange, apple or abacus is displayed. In addition, the image of a mandarin orange and an apple can be used, for example, when teaching the problem of arithmetics like "two oranges, three apples ...".

  As described above, when one of the material display menus M2 to M7 is selected and operated, the electronic white plate device 1 of the first embodiment is subsequently selected at the operation position at which the drawing area 1a is touched. It is the structure which displays the raw material image. In addition, without waiting for a touch operation performed on the drawing area 1a, the corresponding material image is displayed at a predetermined position of the drawing area 1a when any of the material display menus M2 to M7 is selected and operated. May be In this case, since the desired material image can be displayed on the display panel 12a (the drawing area 1a) only by the selection operation on the material display menu M2 to M7, operability is good.

After the process of step S7, or when it is determined that the touch operation is not performed on the drawing area 1a in step S6 (S6: NO), the control unit 10 is displayed in the menu area 1b as in step S4. It is determined whether a selection operation has been performed for any of the menus (S8). When it is determined that the selection operation on any of the menus is not performed (S8: NO), the control unit 10 returns to the process of step S6, and the selection operation is performed every time the touch operation is performed on the drawing area 1a. A material image corresponding to the material display menu M2 to M7 is displayed on the display panel 12a.
If it is determined that the selection operation has been performed on any of the menus (S8: YES), the control unit 10 returns to the process of step S1.

  If it is determined in step S5 that the selection operation has not been performed on any of the material display menus M2 to M7 (S5: NO), the control unit 10 determines whether the selection operation on the enlargement / reduction menu M8 has been performed. It is determined (S9). If it is determined that the selection operation has been performed on the enlargement / reduction menu M8 (S9: YES), the control unit 10 executes the scaling process (enlargement process or reduction process) on any material image displayed in the drawing area 1a. It will be waiting for instructions. Then, the control unit 10 determines whether an execution instruction (magnification change instruction) for the scaling process on any of the material images has been received based on the input operation by the operating tool on the drawing area 1a (S10).

6B and 6C show examples of the display screen when the enlargement / reduction menu M8 is selected, FIG. 6B shows the state at the start of the magnification change instruction, and FIG. 6C shows the end of the magnification change instruction. The state at the time is shown respectively. As shown in FIG. 6B, when the user wants to perform enlargement processing on a scale image (material image), the user first uses, for example, his / her finger F and touch pen P to display the scale image displayed in the drawing area 1a. Touch the left and right ends of the. Thereafter, the user moves (slides) his / her finger F and touch pen P along the drawing area 1a until the desired size is achieved, and ends the touch and slide operations on the drawing area 1a in the state shown in FIG. 6C. .
Therefore, when the touch operation is performed on the drawing area 1a at two places, the control unit 10 determines that the material image subjected to the touch operation is a scaling target. Specifically, the control unit (magnification changing reception unit) 10 receives a material image including two operation positions as a material image to be scaled. Further, the control unit 10 detects the operation position with respect to the drawing area 1a by the touch panel control unit 13 every predetermined time, and whenever the operation position is detected, the area designated at the two operation positions before the predetermined time is An execution instruction of scaling processing for scaling to an area designated by the detected two operation positions is accepted. Therefore, every time the control unit 10 detects the operation position with respect to the drawing area 1a, the control unit 10 receives an instruction to execute the scaling process on the material image subjected to the touch operation.

  When it is determined that the scaling instruction for any of the material images is received (S10: YES), the control unit (magnification processing unit) 10 executes the scaling process based on the processing content of the received scaling instruction (S11) ). Specifically, the control unit 10 executes the scaling process on which the execution instruction has been received on the material image selected by the touch operation on the drawing area 1a. More specifically, the control unit 10 performs a scaling process on the material image data of the selected material image according to the scaling ratio instructed to execute, and the display control unit 12 displays the material image data after the scaling process. Send to Then, the display control unit 12 causes the display panel 12a to display the material image based on the acquired material image data after the magnification change processing, whereby the material image subjected to the magnification change processing is displayed on the display panel 12a. The control unit 10 performs detection of the operation position with respect to the drawing area 1a and scaling processing based on the operation position until the slide operation (input operation) with respect to the drawing area 1a is completed. According to the input operation, the corresponding material image is scaled at any time and displayed.

  As described above, the electronic whiteboard apparatus 1 according to the first embodiment receives the instruction to execute the scaling process on the area indicated by the two operation positions in the drawing area 1a, but the present invention is limited thereto. Absent. For example, when the enlargement / reduction menu M8 is selected, a scaling factor menu for designating a scaling factor may be separately displayed, and a scaling factor may be designated from the scaling factor menu. In this case, for example, the scaling factor is designated through the scaling factor menu, and the material image to be scaled is selected by the touch operation on the drawing area 1a, and thus, the designated material image is designated. The scaling process may be performed according to the scaling factor.

After the process of step S11, or when it is determined that the scaling instruction is not received at step S10 (S10: NO), the control unit 10, like step S4, either of the menus displayed in the menu area 1b It is determined whether or not a selection operation has been performed on the subject (S12). When it is determined that the selection operation for any of the menus is not performed (S12: NO), the control unit 10 returns to the process of step S10, and whenever it receives a scaling instruction for any of the material images being displayed, Perform scaling processing according to the scaling instruction.
If it is determined that a selection operation has been performed for any of the menus (S12: YES), the control unit 10 returns to the process of step S1.

  When it is determined in step S9 that the selection operation on the enlargement / reduction menu M8 is not performed (S9: NO), the control unit 10 determines whether the selection operation on the movement menu M9 is performed (S13). If it is determined that the selection operation on the movement menu M9 has been performed (S13: YES), the control unit 10 waits for a movement instruction for any of the material images displayed in the drawing area 1a. Then, the control unit 10 determines whether a movement instruction for any of the material images has been received based on the input operation by the operating tool on the drawing area 1a (S14).

FIGS. 7A and 7B show examples of display screens when the move menu M9 is selected and operated. FIG. 7A shows a state at the start of the move instruction, and FIG. 7B shows a state at the end of the move instruction. Indicate each state. As shown in FIG. 7A, when it is desired to move the scale image (material image), the user first uses the operation tool (the touch pen P in FIGS. 7A and 7B) to display the scale displayed in the drawing area 1a. Touch the image of. Thereafter, the user slides (moves) the operating body to the desired position along the drawing area 1a, and ends the touch operation and the slide operation on the drawing area 1a in the state shown in FIG. 7B.
Therefore, when the touch operation is performed on the drawing area 1a, the control unit 10 determines that the material image subjected to the touch operation is a movement target. Specifically, the control unit (movement receiving unit) 10 receives a material image including an operation position as a material image to be moved. Further, the control unit 10 detects the operation position with respect to the drawing area 1 a by the touch panel control unit 13 every predetermined time, and receives an execution instruction of movement processing for moving to the detected operation position each time the operation position is detected. Therefore, every time the control unit 10 detects the operation position with respect to the drawing area 1a, the control unit 10 receives an execution instruction of the movement process for the material image subjected to the touch operation.

  If it is determined that the movement instruction for any of the material images is received (S14: YES), the control unit 10 executes the movement process based on the processing content of the received movement instruction (S15). Specifically, the control unit 10 causes the display control unit 12 to move the material image selected by the touch operation on the drawing area 1a to the position instructed to move (the operation position corresponding to the drawing area 1a) ( Display). Note that the control unit 10 performs detection of the operation position with respect to the drawing area 1a and movement processing based on the operation position until the slide operation with respect to the drawing area 1a ends, so that the corresponding material image according to the slide operation with respect to the drawing area 1a The display position of is changed at any time.

  As described above, the electronic whiteboard device 1 according to the first embodiment receives the movement processing execution instruction by the touch operation and the slide operation on the drawing area 1a. However, the invention is not limited to this configuration. For example, when the move menu M9 is selected and operated, a move direction menu for specifying the movement of the drawing area 1a in the left and right direction and the up and down direction is separately displayed, and the move direction is specified from the move direction menu. Good. In this case, for example, the movement direction is specified via the movement direction menu, and the material image to be moved is selected by the touch operation on the drawing area 1a, whereby the specified movement with respect to the selected material image is performed. A movement process according to direction may be performed.

After the process of step S15, or when it is determined that the move instruction is not received at step S14 (S14: NO), the control unit 10, like step S4, either of the menus displayed in the menu area 1b It is determined whether or not the selection operation has been performed for (S16). When it is determined that the selection operation for any of the menus is not performed (S16: NO), the control unit 10 returns to the process of step S14, and follows the movement instruction every time the movement instruction for any material image is received. Perform the move process.
If it is determined that the selection operation has been performed on any of the menus (S16: YES), the control unit 10 returns to the process of step S1.

  When it is determined in step S13 that the selection operation on the movement menu M9 is not performed (S13: NO), the control unit 10 determines whether the selection operation on the magnification coincidence menu M10 is performed (S17). If it is determined that the selection operation has been performed on the magnification matching menu M10 (S17: YES), the control unit 10 is in a waiting state for the touch operation on the drawing area 1a of the touch panel 13a, and whether or not the touch operation is performed on the drawing area 1a The touch panel control unit 13 determines whether or not (S18). If it is desired that the scaling factor of any of the displayed material images be reflected in other material images, the user should perform a touch operation on any display area of the material images being displayed. Specify the material image to be the reference. Therefore, after the magnification matching menu M10 is selected and operated, when the touch operation is performed on the drawing area 1a, the control unit (instruction receiving unit) 10 uses the material image selected (designated) by the touch operation as a reference. An instruction to execute processing of reflecting the scaling factor of this material image on other material images is received.

  If it is determined that the touch operation has been performed on the drawing area 1a (S18: YES), the control unit 10 identifies the material image selected by the touch operation, and the scaling of the material image has already been performed. The scaling factor in the process is specified (S19). The scaling factor in the scaling process already performed on each material image being displayed is stored in the storage unit 11 in association with each material image each time the control unit 10 performs the scaling process. It is also good. The control unit 10 may calculate the scaling factor by comparing the material image based on the material image data stored in the storage unit 11 with the material image being displayed in the drawing area 1 a.

The control unit (magnification processing unit) 10 executes the scaling process with the specified scaling factor on another material image being displayed in the drawing area 1a (S20). As a result, the material images subjected to the scaling process are displayed on the display panel 12a, and the scaling factors of all the material images being displayed in the drawing area 1a can be matched (unified).
FIGS. 8A and 8B show examples of display screens when the magnification matching menu M10 is selected and operated. As shown in FIG. 8A, after the magnification matching menu M10 is selected and operated, when the touch operation is performed on the drawing area 1a using the operation tool (the touch pen P in FIG. 8A), the material image selected by the touch operation ( In FIG. 8A, the scaling factor in the scaling process already performed on the image of the triangular ruler can be reflected on the other material image (the image of the ruler in FIG. 8A). Therefore, as shown in FIG. 8B, for example, the numerical value of the scale of the ruler can be matched with the numerical value of the scale of the triangle.

  As described above, when the magnification matching menu M10 is selected and operated, the electronic white plate apparatus 1 of the first embodiment thereafter changes the scaling factor of the material image selected by the touch operation on the drawing area 1a to another material image Is also reflected. In addition to this, when the magnification matching menu M10 is selected and operated, all material images displayed in the drawing area 1a are, for example, original material images (materials based on material image data stored in the storage unit 11). The display may be switched to an image) or a material image obtained by performing a scaling process on the original material image with a predetermined scaling factor. In this case, since the scaling factors of all the material images displayed in the drawing area 1a can be matched only by the selection operation on the magnification matching menu M10, operability is good.

After the process of step S20, or when it is determined that the touch operation is not performed on the drawing area 1a at step S18 (S18: NO), the control unit 10 is displayed in the menu area 1b as in step S4. It is determined whether a selection operation has been performed for any of the above menus (S21). When it is determined that the selection operation for any of the menus is not performed (S21: NO), the control unit 10 returns to the process of step S18, and performs the touch operation every time the touch operation is performed on the drawing area 1a. A process of reflecting the scaling factor of the selected material image on other material images is performed.
When it is determined that a selection operation has been performed on any of the menus (S21: YES), the control unit 10 returns to the process of step S1.

  If it is determined in step S17 that the selection operation on the magnification matching menu M10 is not performed (S17: NO), that is, if the selection operation on the eraser menu M11 is performed, the control unit 10 touches the drawing area 1a It will be waiting for the operation. Then, the control unit 10 causes the touch panel control unit 13 to determine whether the touch operation has been performed on the drawing area 1a (S22). The user designates a character or picture (handwritten information) or a material image to be deleted by a touch operation on the drawing area 1a. Therefore, when it is determined that the touch operation has been performed on the drawing area 1a (S22: YES), the control unit (erasing unit) 10 executes the eraser process based on the portion where the touch operation is performed on the drawing area 1a (S23) ). Specifically, the control unit (erase receiving unit) 10 receives the character or picture (handwritten information) being displayed at the location where the touch operation is performed by the touch operation on the drawing area 1a, or the erasing instruction for the material image, and erases it. Delete the indicated character, picture or material image (end the display).

  If the touch area of the operating tool on the touch panel 13a (drawing area 1a) is equal to or larger than a predetermined size without providing the eraser menu M11, characters, pictures, material images, etc. included in the touch area are erased. You may do so. In this case, the eraser process can be performed by the user using an operation tool whose touch area on the touch panel 13a is equal to or larger than a predetermined size, for example, a blackboard eraser.

After the process of step S23, or when it is determined that the touch operation is not performed on the drawing area 1a in step S22 (S22: NO), the control unit 10 is displayed in the menu area 1b as in step S4. It is determined whether a selection operation has been performed for any of the menus (S24). When it is determined that the selection operation on any of the menus is not performed (S24: NO), the control unit 10 returns to the process of step S22, and the touch operation is performed every time the touch operation is performed on the drawing area 1a. Perform eraser processing based on location.
If it is determined that a selection operation has been performed for any of the menus (S24: YES), the control unit 10 returns to the process of step S1.

  The control unit 10 of the electronic whiteboard device 1 performs the above-described processing until, for example, the end of the operation is instructed by turning off the power button (not shown). Therefore, the electronic whiteboard apparatus 1 of the first embodiment can display information input by handwriting to the drawing area 1a on the display panel 12a, and via the material display menus M2 to M7 displayed in the menu area 1b. The selected material image can be displayed on the display panel 12a. In addition, when the enlargement / reduction menu M8 displayed in the menu area 1b is selected and operated, the electronic whiteboard apparatus 1 of the first embodiment displays an arbitrary material image being displayed in the drawing area 1a in an enlarged or reduced size. Can. In addition, when the moving menu M9 displayed in the menu area 1b is selected and operated, the electronic whiteboard apparatus 1 of the first embodiment moves (changes) the display position of an arbitrary material image being displayed in the drawing area 1a. Can. In the electronic whiteboard apparatus 1 of the first embodiment, when the magnification matching menu M10 displayed in the menu area 1b is selected and operated, the scaling factor of any material image displayed in the drawing area 1a is converted to another material image. Can be reflected and displayed. Furthermore, when the eraser menu M11 displayed in the menu area 1b is selected and operated, the electronic whiteboard apparatus 1 of the first embodiment can erase any character, picture or material image displayed in the drawing area 1a. .

  Hereinafter, the process performed by the electronic whiteboard apparatus 1 when the abacus menu M7 is selected and operated will be described. FIG. 9 is a schematic view showing an example of a display screen by the electronic whiteboard device 1 of the first embodiment, and shows an example of a display screen when the abacus menu M7 is selected and operated. As shown in FIG. 9A, when the abacus menu M7 is selected and operated, the control unit 10 causes the display panel 12a to display a material image of the abacus at the operation position on the touch panel 13a. A user who wants to operate the displayed abacus performs a touch operation on the display area of the bead that he wants to move. Therefore, when the material image of the abacus is displayed, the control unit (abacus operation receiving unit) 10 receives a movement instruction for the bead operated by the touch operation by the touch operation on each bead of the abacus being displayed. Therefore, the control unit 10 determines, with the touch panel control unit 13, whether or not the touch operation has been performed on any of the beads of the abacus displayed in the drawing area 1a, and for any of the beads. When it is determined that the touch operation has been performed, the touch operated bead is appropriately moved. For example, when the hatched bead in FIG. 9A is touch-operated, as shown in FIG. 9B, the touch-operated bead is moved (moving upward in FIG. 9B).

The abacus is used by the user moving (operating) each bead according to a predetermined rule. Therefore, when the touch operation is performed on any of the beads by previously setting the direction to move in accordance with the predetermined rule, the movement direction of the touch operated bead is determined according to the predetermined rule. Can. The beads may be moved according to the touch operation and the slide operation from the touch operation as well as the touch operation on the beads (touch panel 13a) of the abacus. For example, when a touch operation is performed on a certain bead and a slide operation is performed upward along the drawing area 1a from the touch-operated location, the display position of the bead is changed upward. It may be configured.
Even in the state where the material image of the abacus is displayed as shown in FIGS. 9A and 9B, the user selects and operates the enlargement / reduction menu M8 and issues a magnification instruction by an input operation to the drawing area 1a. It is possible to execute scaling processing on the material image.

  In the electronic whiteboard apparatus 1 according to the first embodiment, a scale menu M2, a triangle ruler menu M3, a protractor menu M4, an orange menu M5, an apple menu M6, and an abacus menu M7 are displayed in the menu area 1b as the material display menu. Then, when the user selects each of the material display menus M2 to M7, the material images of the ruler, the triangle, the protractor, the orange, the apple, and the abacus are displayed on the display panel 12 (drawing area 1a). . As material images to be displayed on the display panel 12, other material images such as a compass, a calculator, graph paper, graph paper, staff, English ruled lines, and manuscript paper can be considered, for example. Therefore, each material image data for displaying each material image such as a compass, calculation rule, graph paper, graph paper, staff, English ruled lines, and manuscript paper on the display panel 12a is stored in the storage unit 11, It is also possible to display each menu for instructing to display each of these material images in the drawing area 1a in the area 1b.

Second Embodiment
The electronic whiteboard apparatus according to the second embodiment will be described below. The electronic whiteboard device of the second embodiment has the same configuration as the electronic whiteboard device 1 of the first embodiment described above, and thus the description of the configuration will be omitted. Further, the electronic whiteboard device 1 of Embodiment 2 performs the same processing as the electronic whiteboard device 1 of Embodiment 1 described above, and performs the following processing.

A process performed by the electronic whiteboard device 1 of the second embodiment when handwriting input to the touch panel 13a will be described below. FIG. 10 is a flowchart showing the procedure of processing by the electronic whiteboard device 1 of the second embodiment.
In the electronic whiteboard device 1 of the second embodiment, when a selection operation is performed on the pen menu M1 displayed in the menu area 1b, the control unit 10 is in a state of waiting for handwriting input via the drawing area 1a. It is determined whether handwriting input has been performed on the drawing area 1a (S31). When it is determined that the handwriting input is not performed (S31: NO), the control unit 10 stands by until the handwriting input is performed.

  If it is determined that the handwriting input has been performed (S31: YES), that is, if the user draws a character or a picture on the drawing area 1a with the operation tool, the control unit 10 displays the drawn information (touch operation It is determined whether or not the position) matches the straight line portion in any of the material images being displayed in the drawing area 1a (S32). Specifically, the control unit 10 causes the operation position calculated by the touch panel control unit 13 to be a linear portion in any material image (for example, an image of a ruler, a triangle ruler, or a protractor) displayed in the drawing area 1a. It is determined whether it is in the vicinity (more specifically, within a predetermined range from the straight line portion). Then, when the control unit 10 determines that the operation position is in the vicinity of the straight line portion, it determines that the drawn information matches the straight line portion in the material image being displayed.

  When it is determined that the drawn information matches the straight line portion in any of the material images (S32: YES), the control unit 10 causes the display control unit 12 to select a straight line segment (straight line) matching the straight line portion. It displays on the display panel 12a (S33). Specifically, the control unit 10 sets a position closest to the operation position calculated by the touch panel control unit 13 as a display position in the straight line portion in which the drawn information is determined to match, and this display position is used as a display panel Plot at 12a. When it is determined that the drawn information does not match the straight line portion in the material image being displayed (S32: NO), the control unit 10 causes the display control unit 12 to display the information (handwritten information) input by handwriting. Display on 12a (S34).

  The control unit 10 calculates an operation position every predetermined time while being input by handwriting to the drawing area 1a, and determines whether the calculated operation position matches a straight line portion in any of the material images. , Display of straight line or handwritten information according to the judgment result. Thereby, when the line segment which traced the straight line part in the material picture under display is inputted by handwriting, a straight line segment can be displayed. Therefore, it is difficult to draw a straight line segment when drawing a line segment by freehand handwriting input, but draw (display) a straight line segment based on the straight line portion in the material image being displayed. Can. In addition, information input by handwriting can be displayed regardless of the material image being displayed.

  In addition, when the handwriting input of one stroke is performed, it may be determined whether the information (trajectory) of the handwritten one stroke corresponds to the straight line portion in any of the material images. That is, when the handwriting input for one stroke is completed, it may be determined whether the drawn information matches the straight line portion in any of the material images. In this case, when the information of one stroke matches the straight line portion in any of the material images, the information of the handwritten one stroke can be displayed on the display panel 12a as a straight line segment.

A process performed by the electronic whiteboard device 1 of the second embodiment when the moving menu M9 is selected and operated will be described below. FIG. 11 is a flowchart showing the procedure of processing by the electronic whiteboard device 1 of the second embodiment.
In the electronic whiteboard apparatus 1 of the second embodiment, when a selection operation is performed on the move menu M9 displayed in the menu area 1b, the control unit 10 performs a process for any material image displayed in the drawing area 1a. It becomes a state of waiting for movement instructions. Then, based on the input operation by the operating tool on the drawing area 1a, the control unit 10 determines whether a movement instruction for any of the material images has been received (S41). Specifically, the control unit 10 determines whether the user has performed a touch operation on any of the material images displayed in the drawing area 1a by the operating body, and then performed a slide operation. If it is determined that the movement instruction has not been received (S41: NO), the control unit 10 waits until the movement instruction is received.

  When it is determined that the movement instruction for any of the material images is received (S41: YES), the control unit 10 determines whether or not there is a material image (reference material) as a reference for the movement process based on the received movement instruction. (S42). Specifically, the control unit 10 determines whether or not the material image selected as the movement target by the touch operation on the drawing area 1a is in contact with another material image being displayed in the drawing area 1a. If the processed material image is in contact with any other material image, it is determined that there is a reference material. If it is determined that the reference material is present (S42: YES), the control unit 10 executes a movement process along the periphery of the reference material (S43). Specifically, the control unit 10 causes the display control unit 12 to move and display the material image selected as the movement target along the periphery of the reference material to the position instructed to move. If it is determined that the reference material is not present (S42: NO), the control unit 10 executes the movement processing according to the processing content of the received movement instruction (S44).

  According to the processing described above, when a material image that the user wants to move is in contact with another material image, it can be moved along the periphery of the other material image. Therefore, when the material image that the user wants to move is in contact with the straight line portion in the other material image, the movement along the straight line portion becomes possible.

  FIG. 12 is a schematic view showing an example of a display screen by the electronic whiteboard device 1 of the second embodiment. By performing the above-described processing, in the electronic whiteboard device 1 of the second embodiment, for example, as shown in FIG. 12A, the material images of the ruler and the triangular ruler are displayed in contact with each other at the linear portions, When the pen menu M1 is selected and a line segment tracing a straight line portion in the vertical direction of the triangle displayed in the drawing area 1a is input by handwriting, a straight line segment matching the straight line portion is displayed on the display panel 12a. Is displayed. Next, when a movement instruction is performed on the material image of the triangular ruler displayed in the drawing area 1a as shown in FIG. 12B, the material image of the triangular ruler moves along the straight line portion in the material image of the ruler. Be done. Furthermore, as shown in FIG. 12C, when a line segment drawn by tracing a straight line portion in the vertical direction of the moved triangle is hand-written, a straight line segment corresponding to the straight line portion is displayed on the display panel 12a. . Therefore, by using the electronic whiteboard device 1 of the second embodiment, not only straight line segments but also parallel lines can be easily drawn.
