FIG. 4 is a diagram showing a specific example of a light emitting device. FIG. 4 shows a surface-emitting laser 30, which is one specific example of the light-emitting device provided in the three-dimensional processing apparatus 300 of FIG. The surface emitting laser 30 has a plurality of light emitting points 32 each capable of emitting a laser 34 .

In the specific example shown in FIG. 4, a plurality of light-emitting points 32 are arranged two-dimensionally in the XY plane, and each light-emitting point 32 is distributed over the entire area of the printing sheet 20 arranged parallel to the XY plane. , the laser 34 can be irradiated (can emit light) to the printing sheet 20 from the above.

In the cutting process (cutting process) executed by the cutting processing unit 340 of the three-dimensional processing apparatus 300, a plurality of light emitting points 32 corresponding to each of a plurality of cut locations on the printing sheet 20 to be cut are cut into a plurality of A laser beam is radiated to the cut portion at once.

Laser irradiation (light emission) by each light emitting point 32 is controlled by an irradiation control unit (FIG. 1). Under the control of the irradiation control unit, the laser is irradiated at once from a plurality of light emitting points 32 corresponding to a plurality of cut locations. For example, lasers are emitted simultaneously from the plurality of light emitting points 32 .

For example, by causing a plurality of light emitting points 32 corresponding to a plurality of cut points to emit light according to the irradiation timing indicated by a common (one) trigger signal, the timing of light emission (irradiation) by the plurality of light emitting points 32 can be adjusted. You can synchronize. It should be noted that the laser beams may be emitted at once from a plurality of light emitting points 32 corresponding to a plurality of cut locations with minute time differences (for example, 1 second or less) that can be regarded as simultaneous.

The irradiation control unit (FIG. 1) irradiates a laser 34 from each light emitting point 32 corresponding to the position of the cut portion indicated by the cutting data of the print sheet 20 for each print sheet (sheet member) 20 to the cut portion. .

FIG. 5 is a diagram showing a specific example of the cut data 142. As shown in FIG. FIG. 5 shows a specific example of the cut data 142 generated by the cut data generator 140. As shown in FIG. The cut data generation unit 140 generates cut data 142 indicating the position of a cut portion to be cut within the sheet member for each sheet member.

In the specific example shown in FIG. 5, the cut data 142 is divided into a plurality of sections 144 . For example, the cutting data 142 is divided into a plurality of sections 144 such that the position of one section 144 corresponds to the position of one light emitting point 32 (FIG. 4) of the surface emitting laser 30 .

The cut data generation unit 140 generates cut data 142 for each sheet member from the two-dimensional image data 132 (FIG. 2) of each sheet member by a predetermined conversion process. A specific example of the conversion process is as follows.

For example, a plurality of cut points are arranged along the cross-sectional contour 134 of the stereoscopic data 122 (FIG. 2) included in the two-dimensional image data 132 . Also, a plurality of cut points may be arranged in the blank area outside the cross section surrounded by the outline 134 . By arranging a plurality of cut portions in the blank area, it becomes easier to remove the blank than in the case where the cut portions are not provided in the blank area.

Moreover, a plurality of cut points may be arranged discretely. For example, a plurality of cut points arranged along the outline 134 are arranged at predetermined intervals, and a plurality of cut points arranged in the blank area are also arranged at predetermined intervals. The intervals between the cut points arranged along the outline 134 and the intervals between the cut points arranged in the blank area may be different from each other. By discretely arranging a plurality of cut portions, each sheet member is suppressed from being scorched by laser irradiation, as compared with the case where a plurality of cut portions are arranged continuously.

For example, the cut data generation unit 140 sets the data value of the section 144 that is the cut point among the plurality of sections 144 to "1", and sets the data value of the other sections 144 other than the cut point to "0". Generate data 142 . Note that the cut data 142 may be generated to identify the cut portion and other portions with data values other than "1" and "0". For example, as the data value of the section 144 to be cut, a value indicating the irradiation intensity of the laser for that section 144 is used, and the irradiation control unit (see FIG. 1) controls each light emitting point 32 (see FIG. 4) based on the data value. ) may control the irradiation intensity of the laser.

FIG. 6 is a diagram showing a specific example of laser irradiation intensity. FIG. 6 shows a specific example of the irradiation intensity of the laser emitted from each light emitting point 32 (FIG. 4) corresponding to each section 144 indicated by the cutting data 142 (FIG. 5).

FIG. 6(1) shows a specific example of laser beams emitted from the light-emitting point 32 corresponding to the section 144 to be cut to the section 144 . In the specific example of FIG. 6(1), the laser is irradiated with the center P of the section 144 serving as the cut point as the focal point. When the laser is irradiated with the center P as the focal point, the irradiation intensity of the laser becomes maximum at the position of the center P, and the irradiation intensity of the laser gradually decreases as the distance from the center P increases.

In the specific example shown in FIG. 6(1), the sheet member is perforated in a region where the laser irradiation intensity is 50 or higher. As a result, for example, as illustrated in FIG. 6(1), a circular cut hole with a center P is formed in the section 144 that is to be cut.

On the other hand, FIG. 6(2) shows a specific example of the section 144 other than the cut portion. The laser is not irradiated to the section 144 other than the cut portion.

In the cutting process (cutting process) executed by the cutting processing unit 340 of the three-dimensional processing apparatus 300 of FIG. A plurality of cut locations are irradiated with a laser at once, and a plurality of cut locations in each sheet member are cut at once. Therefore, the time required for cutting each sheet member by the three-dimensional processing apparatus 300 in FIG. 1 can be shortened, compared to the cutting process in which each sheet member is gradually cut while moving a laser or a blade.
