  By the way, thermal expansion of the thermally expandable sheet is more conspicuous in image formation on the front surface side (one surface side) than in image formation on the back surface side (other surface side). Therefore, according to the shape of the image (for example, the thickness or area of the line), the optimal image formation is selected by appropriately selecting whether to form an image on one side of the thermally expandable sheet or on the other side. It is preferable to

In this respect, the technique described in Patent Document 1 intends to image the heat absorbing portion of black or ash only on one side of the thermally expandable sheet and to image the heat absorbing portion on the other side. Not. Therefore, this technique forms an image of a graph-shaped heat absorption part only on one side of the thermally expandable sheet even when a graph is formed as a three-dimensional image.
In other words, since the technique described in Patent Document 1 does not select whether to form an image on one side of the thermally expandable sheet or to form an image on the other side, more appropriate stereoscopic image formation (manufacturing a three-dimensional object) Have the potential to do.

(First embodiment)
FIG. 1 is a configuration diagram of a stereoscopic image forming system according to the first embodiment of the present invention.
The three-dimensional structure manufacturing system 1000 includes a display device 100, a display operation unit 150, a two-dimensional image forming device 320, and a foaming device 310, and the two-dimensional image forming device 320 and the foaming device 310 include the three-dimensional image forming device. 300 is configured. The stereoscopic image forming apparatus 300 forms a stereoscopic image such as a bar graph or a pie chart on a thermally expandable sheet. Further, the display device 100 causes the display operation unit 150 to display an image such as a bar graph or a pie graph for image formation. Note that the bar graph and the pie chart are composed of a plurality of bars and a plurality of sectors, and are compared with each bar and the area and area ratio of the sectors.

  The display device 100 is a general-purpose information processing device connected to the display operation unit 150 using an OS (Operating System), and is used as a control device that controls the foaming device 310 and the two-dimensional image forming device 320. The display device 100 includes a control unit 10, a volatile storage unit 80, a nonvolatile storage unit 90, and a communication unit 70. The volatile storage unit 80 is a RAM (Random Access Memory), and is used as a work memory. The nonvolatile storage unit 90 is an HDD (Hard Disk Drive) or ROM (Read Only Memory), and stores an OS 91, an application program 93, a printer driver 92, graph data 94, and the like. The communication unit 70 is a LAN (Local Area Network) or USB (Universal Serial Bus) serial interface or parallel interface. In this embodiment, the two-dimensional image forming apparatus 320 is connected by USB, and the foaming apparatus 310 is connected serially or in parallel. The display operation unit 150 is a touch panel connected to the display device 100, and includes display means for displaying a two-dimensional image and input means for input by an operator.

  The foaming device 310 is a halogen lamp as a heating device (heating device) for heating one or both sides of a thermally expandable sheet in which a foam layer (expanding layer) that is foamed (expanded) by heat is laminated on one side of the mount. (Not shown).

  The two-dimensional image forming apparatus 320 performs black printing (drawing) for foaming (expanding) a specific portion of the thermally expandable sheet, or color printing the entire surface of the thermally expandable sheet with CMY (cyan, magenta, yellow). Inkjet printer. The two-dimensional image forming apparatus 320 includes image data (surface data) of a specific part that expands the surface of the thermally expandable sheet, image data (back surface data) that expands the expansion layer from the back surface of the thermally expandable sheet, and a color image. Data is needed.

  Since the halogen lamp strongly generates near-infrared light, black (carbon) is strongly heated, and the amount of heating is small at the CMY color printing location. For this reason, the thermally expandable sheet having the foam layer is foamed (expanded) only at the specific portion printed in black, and a three-dimensionally shaped object is formed. In other words, the two-dimensional image forming apparatus 320 prints a heat conversion layer (black layer) that converts near-infrared light into heat. Here, the ink for black printing contains carbon and contributes to foaming by irradiation with near-infrared light. CMY inks do not contain carbon. For this reason, black mixed with CMY has a small calorific value and does not contribute to foaming. The three-dimensional structure manufacturing system 1000 operates as a structure manufacturing system that manufactures a three-dimensional image structure.

  The control unit 10 is a CPU (Central Processing Unit), and by executing a program, the setting unit 20, the display control unit 30, the input control unit 40, the image formation control unit 50, the communication control unit 60, and the like.

And color image data for image formation. The setting unit 20 includes a boundary region / allocation unit 21, an inner region / allocation unit 22, and an axis / scale / allocation unit 23. The boundary area / assignment means 21 assigns a boundary between a bar of a bar graph, a sector of a pie chart and the background, and a boundary between adjacent areas. The inner area / assignment means 22 assigns the area inside the bar of the bar graph or the area inside the pie chart. The axis / scale / assignment means 23 assigns the axis and scale of the graph to the surface data. The color image data is assigned as a color image on the surface, but does not contribute to thermal expansion.

  The image formation control unit 50 is a control unit that controls both the two-dimensional image formation apparatus 320 and the foaming apparatus 310 based on the graph data 94.

  The communication control unit 60 is a control unit that controls the communication unit 70, controls the two-dimensional image forming apparatus 320 by USB (Universal Serial Bus), controls the foaming apparatus 310 by a parallel I / F or a serial I / F, A digital video signal is transmitted to the display operation unit 150.

The bar graph 420 includes an area expression unit 410 that represents the area of a bar, a horizontal scale line 421, a vertical scale line 422, an item 423, a scale 424, and a background 415. The area expression unit 410 includes an inner region 411 that is an inner region (open region) of the bar, and a second boundary region 413 that is a boundary with the background 415. An open region is a concept that does not include a boundary, and a concept that includes a boundary is referred to as a closed region. The inner region 411 is a portion obtained by excluding the second boundary region that is the outer peripheral portion of the bar of the bar graph 420 from the area expressing unit 410, and has an area. The bar graph 420 is a graph with the number of series 1 and the number of data 3. Each item 423 describes one piece of data, and the number of items is three. Here, the series means a group of data of the same system.

  The horizontal scale lines 421 are a plurality of horizontal lines drawn at equal intervals and in parallel, and are reference lines for comparing the heights of the bars. The vertical scale lines 422 are a plurality of vertical lines drawn at equal intervals and in parallel, and are used for distinguishing between adjacent bars, and may be omitted. Item 423 is a character string describing the contents of each bar. The scale 424 is a character string that quantitatively represents the height of the bar, and corresponds to the horizontal scale line 421. The scale 424 is provided with a space between the leftmost vertical scale line 422, and for example, braille is written in this space.

FIG. 3 is an explanatory diagram showing an example of a pie chart.
The pie chart 430 includes an area expression unit 410 that represents a fan-shaped area and a background 415. The area expression unit 410 has a first boundary that is a boundary between the inner region 411 (411a) and the adjacent inner region 411b. A region 412 and a second boundary region that is a boundary between the background 415 and the region 412 are provided. In addition, the pie chart may not be a sector shape obtained by dividing a circle radially, but may be a shape obtained by dividing a donut radially.

The degree of completion and satisfaction of the items 443 of each axis 441 are quantitatively described, and the balance of the items 443 is evaluated.

  Here, in each axis 441, a point P for quantitatively describing the degree of completion and satisfaction is defined by a distance and a ratio from the center O, and when the points P of each axis 441 are connected by a straight line, many points are obtained. A square is formed. The polygon can be evaluated for the degree of completion and satisfaction with the ratio of the outermost circle to the area, and is expressed as an area expression unit 410. The area expression unit 410 includes an inner region 411 that is an inner side of a polygon and a second boundary region that is a boundary with the background 415.

FIG. 5 is a flowchart for explaining the operation of the display device of the three-dimensional structure manufacturing system.
The graph image generation means 41 displays the graph selection setting screen on the display operation unit 150 (S10). Specifically, the graph image generation unit 41 first displays the application selection screen 450 (FIG. 6), and confirms that the table input graph application selection button 451 (FIG. 6) is pressed, then creates the graph creation screen 500 (FIG. 7). , FIG. 8) is displayed. The graph image generating means 41 selects either a bar graph or a pie graph using the pull-down menu in the graph type selection field 510. FIG. 7 is a screen in which a pie chart is selected in the graph type selection column 510a, and FIG. 8 is a screen in which a bar graph is selected in the graph type selection column 510b. Here, it is assumed that the operator selects a bar graph (FIG. 8) and inputs the number of series “2” and the number of data “3” using the numeric keypad 520.

  The graph creation screen 500 includes a combination of a “stop” button 521, a “return” button 522, and a “next” button 523, and cancels graph creation (for example, returns to the menu screen). It is possible to return to the screen (for example, the application selection screen 450) and proceed to the next screen.

  After S10, the input control means 40 causes the display / operation unit 150 to display an X-axis / Y-axis setting screen (S15). That is, the input control means 40 displays the axis information input screen 540 (FIG. 9). The axis information input screen 540 has a check box 541 for displaying the X-axis graticule, a check box 542 for displaying the vertical grid line, and a check for setting whether to open the braille display area. A box 543 is provided. In addition, the axis information input screen 540 includes an input field 545 for inputting the minimum value and the maximum value of the Y axis using the numeric keypad 520. The axis information input screen 540 also sets a check box 546 for displaying a Y scale line, a check box 547 for displaying a vertical grid line, and whether to open a braille display area. A “scale interval” input field 549 that is set using a check box 548 and a numeric keypad 520 is provided.

  After displaying the X-axis and Y-axis setting screen (axis information input screen 540 (FIG. 9)) in S15, the input control means 40 inputs scale data such as the minimum and maximum values of the Y-axis and the scale interval. Perform (S20). After S20, the graph image generating means 41 calls a symbol (foaming pattern table 545 (FIG. 10)) set for each series (S25).

FIG. 10 is an example of a foam pattern table.
The foam pattern table 545 is stored in the nonvolatile storage unit 90, and registers the foam pattern and color shown in the figure for each series. That is, the three-dimensional structure manufacturing system 1000 of the present embodiment is configured such that the foam pattern and color are automatically selected according to the series. The colors are, for example, series 1 is red, series 2 is yellow, series 3 is green, series 4 is dark blue, series 5 is blue, series 6 is light green, It is assumed that series 7 is pink and series 8 is sunflower. In some cases, as in series 4, there is no foam pattern.

  Returning to the description of FIG. 5, after the processing of S25, the input control means 40 inputs graph data using the graph data input screen 550 (FIG. 11) (S27). For graph data, for example, the graph data 94 stored in advance in the nonvolatile storage unit 90 may be read without using the graph data input screen 550.

FIG. 11 is a diagram illustrating an example of a graph data input screen.
The graph data input screen 550 includes a series 1 data column 551 and a series 2 data column 552 for each data label. For example, for label 1, “10” is input to series 1, “8” is input to series 2, label “15” is input to series 1, “5” is input to series 2, and label 3 is “12” is input to the series 1 and “10” is input to the series 2.

After S27, the graph image generating means 41 generates an image of the inner area (S30).
FIG. 12 is a flowchart for explaining a generation operation for generating the inner region image.
First, the boundary area / assignment means 21 (FIG. 1) duplicates the image of the boundary area (S31). That is, the boundary area / assignment means 21 duplicates the image of the second boundary area 413 (FIG. 2) and generates the image of the second boundary area 413a (FIG. 13). After S31, the inner region / allocation means 22 (FIG. 1) generates an image of the inner region 411c (FIG. 14), and uses the generated image as a temporary image (S33). After S33, the inner area / assignment unit 22 changes the thickness of the second boundary area 413a (S35), and generates an image of the second boundary area 413b (FIG. 15). After S35, the inner area / assignment means 22 changes the color of the second boundary area 413b to white (S37). After S37, the inner region / assignment unit 22 superimposes the image of the white region (second boundary region 413b) and the image of the inner region 411c (FIG. 14) (S39), and superimposes the inner region 411d ( The image in FIG. 16) is assigned as the back surface foam image. That is, the inner area 411d as the back surface foamed image has a similar shape smaller than the second boundary area 413a. Then, the process returns to the original routine (FIG. 5).

  After S30, the display control means 30 (FIG. 1) displays the bar graph display screen 560 (FIG. 17) on the display operation unit 150 (FIG. 17) (S35).

FIG. 17 is an example of a bar graph display screen.
The bar graph display screen 560 includes a combination of the bar graph 420 (series 1) described with reference to FIG. 2, a “stop” button 521, a “return” button 522, and a “next” button 523. That is, the operator cancels the graph creation (for example, returns to the menu screen), returns to the previous screen (for example, the graph data input screen 550 (FIG. 11)), and the next screen (for example, the second screen). It is possible to proceed to a graph editing screen 570 (FIG. 19)) for series addition.

  After S35, the input control means 40 determines whether to check the axes and symbols (S40). If it is determined that the symbol needs to be reset (symbol / resetting in S40), the display control means 30 displays the symbol correction screen 530 (FIG. 18) on the display operation unit 150 to correct the symbol (S45). ).

FIG. 18 is an example of a symbol correction screen.
The symbol correction screen 530 is a screen for setting a bar pattern and a bar color (background color) for each series. The screen of FIG. 18 is set to “dot pattern” and “red”. After S45, the process returns to S30 to regenerate the image of the inner area.

  On the other hand, if it is determined that the axis needs to be reset (axis / reset in S40), the display control means 30 returns the process to S15, and the input control means 40 displays the axis information input screen 540 (FIG. 9). Let At this time, the display control means 30 can also display a graph editing screen 570 (FIG. 19) to edit lines and add series.

FIG. 19 is a diagram illustrating an example of a graph editing screen.
The graph editing screen 570 includes a bar graph 425 in which a “series 2” bar is added to the “series 1” bar graph 420 described in FIG. 2 and a line type change screen 580. The line type change screen 580 is a screen for changing the line type such as the horizontal scale line 421 and the vertical scale line 422. The “line color”, “line type”, “line thickness”, “foam height” Can be changed.

  If the axis / symbol is OK (confirmation is OK in S40), the input control means 40 performs graph determination input (S50). If re-input of data is necessary (re-input of data in S50), the input control means 40 returns the process to S27 to input graph data.

  On the other hand, if the determination result indicates that the displayed graph is appropriate (image formation in S50), the image formation control unit 50 (FIG. 1) performs a tertiary operation on the two-dimensional image formation apparatus 320 and the foaming apparatus 310. An instruction to form an original image is given (S55).

  First, the image forming control unit 50 uses the two-dimensional image forming apparatus 320 to perform horizontal scale lines 421, vertical scale lines 422, items 423, scales 424, second boundary areas 413a, and first boundary areas 412 (FIG. 3). ) Is formed on the surface of the thermally expandable sheet in black (FIG. 20A). The front foam image in FIG. 20A includes a braille image 425. Next, the image formation control means 50 forms a mirror image of the back foam image of the inner region 411d (FIG. 16) on the back side of the thermally expandable sheet, and forms the mirror image in black (FIG. 20B). . In addition, the image formation control unit 50 forms a color image (FIG. 20C) in CMY colors on the surface of the thermally expandable sheet.

  In FIG. 20C, the “yellow” color image is indicated by 411e, and the “red” color image is indicated by 411f. Further, in the color image formation, when the horizontal scale line 421, the vertical scale line 422, the item 423, the scale 424, the second boundary area 413, and the first boundary area 412 are expressed in black, the image formation control means 50 is used. Forms an image using all colors of CMY. Color image formation is non-contributing to thermal expansion because it is not black with carbon.

  FIG. 21 is a diagram showing an example of a composite image of a front foam image, a front color image, and a back foam image made into a mirror image. FIG. 21 shows the cross-sectional positions of the cross-sectional views of FIGS. In FIGS. 21 and 22, as in FIG. 20C, the “yellow” color image is indicated by 411e, and the “red” color image is indicated by 411f.

  Next, the image formation control means 50 uses the foaming apparatus 310 to irradiate the thermally expandable sheet with near-infrared light and form a black imaged portion (the horizontal scale line 421 on the surface side of the thermally expandable sheet, The vertical scale line 422, the item 423, the scale 424, the second boundary area 413, the first boundary area 412, and the braille image 425 are foamed, and the image formation control unit 50 ends the process.

FIG. 22 is an AA cross-sectional view of the thermally expandable sheet before foaming, and the cross-sectional position is shown in FIG.
The thermally expandable sheet is obtained by laminating a foam layer on one side (front side) of the mount. The image of the second boundary region 413a and the vertical scale line 422 is formed in black on the surface side of the thermally expandable sheet before foaming, and the color images 411e and 411f in the inner region 411 are formed on the surface side. The second boundary region 413a is wider than the vertical scale line 422. Further, this thermally expandable sheet has an image of the pattern of the inner region 411d formed on the back side. The second boundary area 413a, the vertical scale line 422, and the pattern of the inner area 411d are formed with the same density. A second boundary region 413b having a changed thickness exists between the second boundary region 413a on the front surface side and the inner region 411d on the rear surface side.

FIG. 23 is an AA cross-sectional view of the thermally expandable sheet after firing, and FIG. 24 is a perspective view of the thermally expandable sheet after firing.
In the thermally expandable sheet after firing, the foam layer corresponding to the second boundary region 413a and the vertical scale line 422 is not only raised on the front side, but also the pattern of the inner side region 411d imaged on the back side. The foam layer corresponding to is also raised on the surface side, and a three-dimensional modeled object (three-dimensional image) is formed. Here, the pattern of the inner region 411d imaged on the back side expands over time, so that the rate of change in the height direction is small and gentle. On the other hand, since the second boundary region 413a imaged on the front side and the vertical scale line 422 are instantaneously expanded, the rate of change in the height direction is large and they rise steeply. Further, the color image of the inner region 411 is formed in the upper layer of a three-dimensional foamed layer. In addition, the pattern of the inner area | region 411d image-formed in black remains on the back surface of a thermally expansible sheet.

  As described above, the three-dimensional structure manufacturing system 1000 according to the present embodiment has a 2.5D image (three-dimensional structure) such as a bar graph or a pie chart on a thermally expandable sheet in which a thermal expansion layer is formed on the surface side (one surface side). An object, a three-dimensional image). Specifically, the three-dimensional structure manufacturing system 1000 assigns the first boundary region 412 and the second boundary region 413 (FIG. 2) to the surface side, and the boundary regions 412 and 413, the horizontal scale line 421, and the vertical scale. Line 422, item 423, scale 424, and braille image 425 are imaged on a thermally expandable sheet with black containing carbon, and an inner area 411 (FIG. 2) is assigned to the back side, and this inner area 411 is black with carbon. An image is formed on a thermally expandable sheet. At this time, the inner region 411d where the back surface foamed image is formed has a similar shape smaller than the second boundary region 413. And the three-dimensional molded item manufacturing system 1000 heats the thermally expansible sheet image-formed with black, and expands a thermal expansion layer. Thereby, as for a thermally expansible sheet, the inner side area | region 411 expands a thermal expansion layer to the surface side over time from the back surface side, and the 1st boundary area | region 412 and the 2nd boundary area | region 413 are thermally expanded immediately on the surface side. Accordingly, the thermally expandable sheet thermally expands so that the first boundary region 412 and the second boundary region 413 on the front surface side are more conspicuous than the inner region 411 on the back surface side. That is, for the thermally expandable sheet, the first boundary region 412, the second boundary region 413, and the inner region 411 are appropriately selected, and optimal image formation is performed.
