[0009] Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. Note that the same reference numerals in each drawing indicate the same elements. In each drawing, the up, down, left, and right directions relative to the paper surface will be used in the description to refer to the up, down, left, and right directions of the components (or parts) in this embodiment.

[0010] First, the configuration of a holding device for holding a printing target corresponding to an embodiment of the present invention will be described. FIG. 1 is a diagram showing an example of the appearance of the holding device. In FIG. 1, the holding device 100 has a holding substrate 102 mounted on a support base 101. In FIG. 1, X, Y, and Z axes are set, and the plane of the holding substrate 102 coincides with the XY plane. A plurality of drive units 103 and a plurality of holding units 104 connected to the drive units 103 are provided on the holding substrate 102. The holding units 104 are arranged in a matrix. In the example shown in FIG. 1, 70 holding units 104 are arranged, with 10 in the row direction (X direction) and 7 in the column direction (Y direction). One drive unit 103 is provided for each row of the holding units 104 arranged in a matrix. The holding units 104 arranged in the same row (X direction) are connected to each other by a shaft, and a driving force from the drive unit 103 is transmitted to the holding substrate 102. The holding substrate 102 can be moved up and down in the Z direction by an elevator device 105.

[0011] Next, the relationship between the driving unit 103 and the holding unit 104 will be described with reference to Fig. 2. Fig. 2 is a side view showing an example of a partial appearance of the holding device 100 as seen from the side.

[0012] As shown in FIG. 2, a plurality of holding units 104 are arranged on a holding substrate 102. The plurality of holding units 104 are connected to one another by shafts 201, and the shafts 201 are connected to a driving unit 103. With this structure, a rotational force is transmitted from the driving unit 103 to the shafts 201. In this embodiment, the rotation of the shafts 201 is converted into the rotation of the orthogonal shafts 203, so that the printing target 202 held on the holding units 104 can be rotated around the axis 203 in the XZ plane. In addition, the holding unit 104 is equipped with a motor 204 that operates based on external control, and by transmitting the rotational force of the motor 204, the printing target 202 can be rotated in the YZ plane around an axis (not shown).

[0013] The lifting device 105 includes a lifting unit 206, a main pulley 207, a guide pulley 208, and a belt 209. A control unit 205 is connected to the underside of the lifting device 105. A control signal is input to the control unit 205 from an external control device, and the control unit 205 can control the rotation of the main pulley 207 in accordance with the control signal. The rotation of the main pulley 207 is transmitted to each lifting unit 206 via the belt 209 and the guide pulley 208. The lifting unit 206 is composed of a pulley 206a, a shaft 206b, and a nut 206c. As the pulley 206a rotates, the shaft 206b connected to the pulley 206a moves up and down in the Z-axis direction. Accordingly, the nut 206c fixed to the shaft 206b moves in the Z-axis direction. Since the nuts 206c are connected to the holding substrate 102, the position of the holding substrate 102 in the Z-axis direction can be adjusted by simultaneously raising and lowering the multiple lifting units 206. This allows the height of the printing target 202 to be adjusted.

[0014] Furthermore, a control signal for controlling the drive unit 103 and the motor 204 is input to the control unit 205 from an external control device. The control unit 205 controls the operation of the drive unit 103 based on the control signal to rotate the shaft 201, and also operates the motor 204 to adjust the inclination of the printing object 202 in the holder 104.

[0015] Next, the structure of the holding portion 104 will be described with reference to Fig. 3 and Figs. 4(A) to 4(E). Fig. 3 is a perspective view showing the appearance of the holding portion 104. Fig. 4(A) is a plan view of the holding portion 104 seen from above. Figs. 4(B) to 4(E) are side views of the holding portion 104 seen from the side.

[0016] Each of the holding units 104 includes a base 301. The size of each holding unit 104 on the holding substrate 102 can be determined by the bottom surface of the base 301. In addition, a recess 301A is formed in the bottom surface of the base, and is used to fix the holding unit 104 on the holding substrate 102.

[0017] The base 301 includes a member 301B for holding the shaft 201, and the member 301B has a through-hole for the shaft 201. The member 301 has a hollow structure, and a first conversion member 302 is attached to the shaft 201 in the hollow portion. The first conversion member 302 is fixed to the shaft 201 and rotates together with the shaft 201. The first conversion member 302 comes into contact with a second conversion member 303 attached to the shaft 203. Since the second conversion member 303 rotates together with the shaft 203, the rotation of the shaft 201 can be transmitted to the orthogonal shaft 203 via the first conversion member 302 and the second conversion member 303. The first conversion member 302 and the second conversion member 303 can each be configured as a gear.

[0018] At this time, the rotation of the shaft 201 occurs in the YZ plane, but this can be converted into rotation of the shaft 203 in the XZ plane via the first conversion member 302 and the second conversion member 303. The shaft 203 is connected to a first holding member 304 that holds the printing target 202. Therefore, by rotating the shaft 201, the first holding member 304 can be rotated in the XZ plane via the shaft 203. A second holding member 305 is connected to the first holding member 304, and a third holding member 306 is connected to the second holding member 305. The third holding member has a structure that can engage with the back side of the printing surface of the printing target 202, and can detachably hold the printing target 202. Therefore, by rotating the first holding member 304 about the shaft 203 as an axis, the printing target 202 can be rotated in the XZ plane.

[0019] 3, motor 204 is disposed within holding portion 104, and shaft 307 is the shaft of motor 204, as particularly shown in FIG. 4(B). Motor 307 is fixed to first holding member 304 by support plate 313. Therefore, when first holding member 304 rotates in response to rotation of shaft 203, motor 204 also rotates together. A space 314 is formed within base 301 so as not to impede the rotation.

[0020] The shaft 307 rotates in the YZ plane in response to the rotation of the motor. A first transmission member 308 is connected to the shaft 307, and the rotation of the motor 204 can be transmitted to the second holding member 305 via the first transmission member 308, the second transmission member 310, and the third transmission member 312. Here, each of the conversion members 308, 310, and 312 can be configured as a gear.

[0021] Shaft 309 is attached to first holding member 304, functions as a rotation axis of second transmission member 310, and does not rotate together with second transmission member 310. Therefore, rotation of second transmission member 310 does not act on first holding member 304. Next, shaft 311 is a shaft that penetrates the tip of first holding member 304 and second holding member 305, and is connected to second holding member 305 and third transmission member 312. As a result, the rotation force of motor 204 transmitted to third transmission member 312 via first transmission member 308 and second transmission member 310 is transmitted to second holding member 305 via shaft 311. As a result, second holding member 305 rotates in the YZ plane.

[0022] In this embodiment, the shaft 203 serves as a rotation axis in the X direction, while the shaft 311, which is perpendicular to the shaft 203, serves as a rotation axis in the Y direction. Positioning the X and Y rotation axes as close as possible to the third holding member 306 can improve the accuracy of the rotational movement. Therefore, in this embodiment, the rotation axes are positioned closer to the third holding member 306, or in other words, the printing object 202, than the power sources of the respective rotation axes. To achieve this configuration, the motor 204 is installed below the shaft 203 and farther from the third holding member 306 and the printing object 202. This is because if the motor 204 were positioned higher, it would occupy a certain space and prevent the shaft from penetrating, which would result in the shaft 203 being positioned farther away from the third holding member 306, etc. Also, by attaching motor 204 to the underside of first holding member 304, the heaviest part is located at the bottom, which lowers the center of gravity and stabilizes the rotation of first holding member 304 about shaft 203. Furthermore, by arranging shaft 203 below shaft 311, there is no longer any restriction from shaft 203, so a wide range of rotation of second holding member 305 about shaft 311 can be ensured.

[0023] Next, the structure of the lifting device 105 will be described with reference to Fig. 5. Fig. 5 is a diagram showing an example of the appearance of the lifting device 105 corresponding to the embodiment of the invention. The lifting device 105 has a main pulley 207, a lifting unit 206, a guide pulley 208, and a belt 209 arranged on a substrate 501. The operation of these components is as described in relation to Fig. 2. Furthermore, a cable 502 extends from the control unit 205 and is connected to a control device such as a personal computer, which will be described later with reference to Fig. 6.

[0024] Next, the configuration of a printing system corresponding to an embodiment of the invention will be described with reference to Fig. 6. Fig. 6(A) is a block diagram showing an example of the configuration of a printing system corresponding to an embodiment of the invention.

[0025] As shown in Figure 6(A), a printing system corresponding to an embodiment of the invention is composed of the above-mentioned holding device 100, an inkjet printer 110 which is a printing device that prints predetermined image information on the surface of a printing object 202 held in the holding device 100, and a control device 120 that controls the operation of the holding device 100 and the printer 110.

[0026] The control device 120 can be configured as, for example, a personal computer, and controls the operation of the holding device 100 to determine the inclination and height of the printing object 202, and provides image information according to the state of the printing object 202 to the printer 110 to perform printing. Printing can be performed in multiple batches, and the inclination and height of the printing object 202 are changed each time printing is performed. When all multiple printings are completed, the printing object 202 is returned to its initial position, and multiple printing objects 202 can be collected together using a set tray.

[0027] Next, the hardware configuration of the control device 120 corresponding to an embodiment of the invention will be described with reference to Fig. 6(B). In Fig. 6(B), a CPU 600 executes application programs, an operating system (OS), control programs, etc. stored in a hard disk drive (hereinafter referred to as HD) 605, and controls temporary storage of information, files, etc. required for program execution in a RAM 602. The operation of the holding device 100 and the printer 110 is controlled via an interface (I / F) 608 to perform printing processing corresponding to this embodiment. The processing in Fig. 9, which will be described later, is also realized by the CPU 600 controlling the entire device by executing the corresponding processing program.

[0028] The ROM 601 stores various data such as basic I / O programs, application programs for executing predetermined processes, etc. The RAM 602 temporarily stores various data and functions as the main memory, work area, etc. of the CPU 600.

[0029] The external storage drive 603 is an external storage drive for realizing access to a storage medium, and can load programs and the like stored in a medium (storage medium) 604 into this computer system. The medium 604 can be, for example, a floppy (registered trademark) disk (FD), CD-ROM, CD-R, CD-RW, PC card, DVD, Blu-ray (registered trademark), IC memory card, MO, memory stick, etc. In this embodiment, the external storage device 605 is a hard disk (HD) that functions as a large-capacity memory. The HD 605 stores application programs, an OS, control programs, related programs, etc. Instead of a hard disk, a non-volatile storage device such as flash (registered trademark) memory may be used.

[0030] The instruction input device 606 corresponds to a keyboard, a pointing device (such as a mouse), a touch panel, etc. The output device 607 outputs commands input from the instruction input device 606 and response outputs from the control device 120 in response thereto. The output device 607 may include a display, a speaker, a headphone jack, etc. The system bus 609 controls the flow of data within the control device 120. The interface (hereinafter referred to as I / F) 608 plays a role in intermediating data exchange with the holding device 100 and the printer 110. Specifically, the I / F 608 is used to send control information from the control device 120 to the holding device 100 and to send print images to the printer 110. The I / F 608 can include both a wireless communication module and a wired communication module.

[0031] Next, the correspondence between the printing object and the printing image will be described with reference to Fig. 7. Fig. 7(A) shows the printing object 202 in the holder 104 tilted to the left. Fig. 7(B) shows the printing object 202 in the holder 104 tilted upward from the front so that the lips protrude. Fig. 7(C) shows the printing object 202 in the holder 104 tilted to the right. Fig. 7(D) is a diagram for explaining the distance between the print head of the printer 110 and the printing surface of the printing object 202.

[0032] 7(A), the left side of the doll's mask, which is the printing object, is positioned on the upper side. In this case, the image to be printed on the printing object 202 corresponds to the left side of the doll's face, as shown in image 700. Here, dark colored parts such as eyes 701 and eyebrows 702 are positioned so as to be located approximately in the center (particularly in the horizontal direction) of the printing image.

[0033] In the orientation of the printing object 202 shown in Figure 7(B), the lips of the doll mask, which is the printing object, are positioned at the top. In this case, the image to be printed on the printing object 202 corresponds to the doll's lips, as shown in image 710. Here, the lips 711 are positioned so as to be positioned approximately in the center of the printed image. In image 710, the skin color around the lips is omitted, but the skin color portion may also be printed at the same time.

[0034] 7(C), the right side of the doll's mask, which is the printing object, is positioned on the upper side. In this case, the image to be printed on the printing object 202 corresponds to the right side of the doll's face, as shown in image 720. Here, dark colored parts such as eyes 721 and eyebrows 722 are positioned so as to be located approximately in the center (particularly in the horizontal direction) of the printing image.

[0035] A printing object 202 held by a holding device 100 corresponding to this embodiment is fixed at a predetermined inclination and height, and then inkjet printing is performed on its surface by a printer 110. As shown in Fig. 7(D) , a print head 730 ejects ink onto the printing object 202 located directly below it while being scanned in the scanning direction indicated by an arrow 731. At this time, the distance d between the print head 730 and the printing object 202 is variable due to the unevenness of the surface of the printing object 202.

[0036] The holding device 100 corresponding to this embodiment adjusts the inclination and height so that the distance d between the printing surface of the printing target 202 held in each holding unit 104 and the print head 730 of the printer 110 falls within a predetermined range. Inkjet printers generally have a distance range within which ink droplets can land and properly reproduce an image. If this distance is D, the value of D can be set to, for example, a range from 0.1 mm to 3 mm. When D=0.1 mm, this represents the shortest distance between the print head and the surface of the printing target 202, and the distance between the print head and the most protruding part of the surface of the printing target during printing is adjusted to 0.1 mm.

[0037] When printing a facial image such as that shown in Figure 7(A) on a doll's mask, which is the printing target 202, the tilt and height of the printing target 202 are adjusted so that the distance d between the surface of the mask on which the eyes and eyebrows are printed and the print head 730 of the printer 110 is within the range D. In this case, the eyebrows are protruding from the surface of the printing target 202, and the eyes are recessed (concave). Therefore, the tilt and height of the printing target 202 are adjusted so that the distance d between the print head 730 and the recessed part of the eyes is within 3 mm. The eyebrows only need to be located within a range of 0.1 mm to 3 mm. The surrounding skin-colored areas, which are located farther from the print head than 3 mm due to the unique unevenness of the face, may be included in a separate image and their tilt and height adjusted before printing. Furthermore, if the skin-colored areas can be printed with ink droplets and some degree of blurring or misalignment is acceptable, they may be included in the printing area as long as the distance d is within a range of 5 mm. The same applies to Figure 7(C). In FIG. 7(B), the lips are printed, so the distance d between the protruding lip portion of the printing object 202 and the print head is 0.1 mm, and the inclination and height of the printing object 202 are adjusted so that the other portions are within a distance range of 3 mm.

[0038] In this embodiment, the control device 120 associates a print image with values for controlling the inclination and height of the print object for each type of print object and stores them in a storage device. Fig. 8 is a table showing an example of such control information.

[0039] The table 800 registers an ID 801, a print image 802, a rotation angle (X axis) 803, a rotation angle (Y axis) 804, and a lift distance (Z axis) 805. The ID 801 registers identification information for identifying the printing object 202. When the printing object 202 is identified, the control device 120 can select an image and control information of the ID corresponding to the identified printing object 202 and control the operation of the holding device 100 and the printer 110.

[0040] The print image 802 is registered with an image to be printed on the print object 202. In this embodiment, it is assumed that three images are prepared for one print object 202 and printed, and therefore three images are registered in association with one ID in the table 800. For example, for the print object 202 with ID 801 of 0001, three images, imageLeft0001, imageTop0001, and imageRight0001, are associated with it. However, the embodiment of the invention is not limited to this, and a greater or lesser number of images may be assigned.

[0041] In the rotation angle (X axis) 803, control information is registered for rotating the printing object 202 around the shaft 203 in the XZ plane by rotating the shaft 203. As the control information, for example, information for rotating from a reset position to a desired angle in the X axis direction can be registered. A different value is registered in the rotation angle (X axis) 803 for each print image 802. Based on the control information, the control unit 205 can drive the drive unit 103 to rotate the shaft 203.

[0042] In the rotation angle (Y axis) 804, control information is registered for rotating the printing object 202 around the shaft 311 in the YZ plane by rotating the shaft 311. As the control information, for example, information for rotating from a reset position to a desired angle in the Y axis direction can be registered. A different value is also registered in the rotation angle (Y axis) 804 for each print image 802. Based on the control information, the control unit 205 can drive the motor 204 to rotate the shaft 311.

[0043] Control information for adjusting the height of the printing target 202 by the lifting device 105 is registered in the lifting distance (Z axis) 805. As the control information, for example, information for raising or lowering the printing target 202 from a reset position to a desired position in the Z axis direction can be registered. A different value is also registered in the lifting distance (Z axis) 805 for each printing image 802. Based on the control information, the control unit 205 can drive the main pulley 207 to raise or lower the lifting unit 206.

[0044] Next, the flow of printing processing in a printing system corresponding to an embodiment of the invention will be described with reference to Fig. 9. Fig. 9 is a flowchart corresponding to an example of processing corresponding to an embodiment of the invention. This processing is executed by a processing unit (CPU 600, etc.) of the control device 120.

[0045] First, in S901, an initialization operation is performed. The initialization operation includes, for example, an operation of resetting the inclination of the holding portion 104 of the holding device 100 and the height of the holding substrate 102 to predetermined initial values. It may also include an operation of resetting the operation of the printer 110. The control device 120 transmits a reset signal to the holding device 100 and the printer 110 to perform the initialization operation.

[0046] Next, in S902, the print medium 202 to be printed in this printing system is selected. This selection includes an operation in which the user selects the type of print medium 202 on the control device 120, and the value of ID 801 is specified in accordance with the selection operation. In the following S903, based on the specified value of ID 801, the corresponding print image and control information (each of the registration information 803 to 805 in FIG. 8) are obtained from table 800.

[0047] In the next step S904, one of the acquired print images is selected and sent to the printer 110. In addition, in step S905, control information corresponding to the selected image is sent to the holding device 100 to operate it, thereby changing the inclination of the holding unit 104 and the height of the holding substrate 102 to match the conditions corresponding to the selected image.

[0048] For example, when an image 700 such as that shown in FIG. 7(A) is selected, the control information corresponding to the image 700 is selected and the control unit 205 of the holding device 100 is operated, thereby adjusting the inclination of the holding portion 104 and the height of the holding substrate 102 so that the printing object 202 is in the state shown in FIG. 7(A).

[0049] In the next S906, the printer 110 is controlled to print the selected images. When printing is completed, in S907, it is determined whether all of the images to be printed for the selected printing object have been printed. If it is determined that all of the images have been printed ("YES" in S907), this processing ends. On the other hand, if there are any unprinted images ("NO" in S907), the processing proceeds to S908 and initialization processing is performed.

[0050] In S908, before controlling the holding device 100 so that it has the tilt and height corresponding to the next print image, an operation is again performed to reset the tilt of the holding portion 104 of the holding device 100 and the height of the holding substrate 102 to predetermined initial values. An operation to reset the operation of the printer 110 is also performed. As in S901, the control device 120 can send a reset signal to the holding device 100 and the printer 110 to perform the initialization operation. Thereafter, the process returns to S904, where an unprinted image is selected and processing continues. In this manner, the process is repeated until all print images associated with the selected printing object in the table 800 have been printed.

[0051] In the above embodiment, the tilt of the holding unit 104 and the height of the holding substrate 102 in the holding device 100 are reset to predetermined initial values each time printing of one print image is completed. However, the embodiment of the invention is not limited to this. For example, after a first print image is selected and the tilt of the holding unit 104 and the height of the holding substrate 102 are adjusted to the corresponding tilt and height and printed, the holding unit 104 and the holding substrate 102 may be adjusted to the tilt and height corresponding to the next second print image without resetting.

[0052] In this case, table 800 registers rotation angles 803 and 804 from the reset position and lift distance 805 for print image 802 that is the first to be printed, but for print images 802 to be printed thereafter, rotation angles 803, 804 and lift distance 805 for adjusting the tilt of holder 104 and height of holding substrate 102 for the current print image from the tilt of holder 104 and height of holding substrate 102 for the immediately preceding print image are registered. For example, assume that the XL1 value of rotation angle 803 for imageLeft0001 when a reset operation is performed is plus 15 degrees, and the XT1 value of rotation angle 803 for imageTop0001 is minus 1 degree. In this case, if a reset operation is not performed in between, after imageLeft0001 is printed, a rotation of minus 16 degrees is required to print imageTop0001, so a value of minus 16 degrees is registered as XT1. In this way, by registering the difference value from the control information of the immediately preceding print image, excluding the print image 802 to be printed first, in the table, the reset operation can be omitted even when switching print images 802 for printing.

[0053] Furthermore, although the above-described embodiment does not specifically specify the order of printing, the order may be selected such that the side of the printing target 202 is printed first, followed by the front. Alternatively, the order may be selected such that the front of the printing target 202 is printed first, followed by the side. Regarding the former, in the example shown in FIG. 7, printing can be performed first under the conditions shown in FIGS. 7(A) and 7(C), and then finally under the conditions shown in FIG. 7(B). In this case, a reset operation may or may not be performed to transition the printing target 202 from the left-facing state shown in FIG. 7(A) to the right-facing state shown in FIG. 7(C), and further to the front-facing up state shown in FIG. 7(C). Furthermore, when transitioning to the front-facing state, a reset operation may be performed only immediately before the transition. This is particularly effective when there is a risk of the accuracy of the tilt of the holding unit 104 decreasing when transitioning from side printing to front printing. In this case, by performing a reset operation before printing on the front side, the tilt can be adjusted to correspond to printing on the front side by fine adjustment from the reset position, which makes it possible to further improve accuracy.

[0054] As described above, according to this embodiment, it is possible to appropriately print on the surface of an uneven printing object. In particular, with the above configuration, when simultaneously printing on multiple printing objects with uneven surfaces, it is possible to simultaneously and accurately adjust the angles of the multiple printing objects so that a virtual plane on the printing object faces the print head properly, and the change in distance from the print head falls within a certain range.
