An exemplary embodiment of the invention will now be described with reference to the drawings. Note that the same reference numerals in each drawing indicate the same elements. Furthermore, in each drawing, the up, down, left, and right directions relative to the paper surface will be used in the description below as the up, down, left, and right directions of the components (or parts) in this embodiment.

First, the configuration of a holding device for holding a printing object according 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, there are 70 holding units 104, 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 the matrix. The holding units 104 arranged in the same row (X direction) are connected to each other by a shaft, and the driving force from the drive unit 103 is transmitted to the holding substrate 102. The holding substrate 102 can be raised and lowered in the Z direction by an elevator device 105.

Next, the relationship between the drive unit 103 and the holding unit 104 will be described with reference to Figure 2. Figure 2 is a side view showing an example of the partial appearance of the holding device 100 when viewed from the side.

As shown in FIG. 2, multiple holding units 104 are arranged on the holding substrate 102. The multiple holding units 104 are connected to one another by shafts 201, which are connected to the drive unit 103. This structure allows a rotational force to be transmitted from the drive unit 103 to the shafts 201. In this embodiment, the rotation of the shaft 201 is converted into the rotation of the orthogonal shaft 203, so that the printing object 202 held on the holding unit 104 can be rotated around the axis 203 in the XZ plane. The holding unit 104 also includes a motor 204 that operates based on external control, and by transmitting the rotational force of the motor 204, the printing object 202 can be rotated in the YZ plane around an axis (not shown).

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. Because 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 multiple lifting units 206. This allows the height of the printing object 202 to be adjusted.

In addition, the control unit 205 receives control signals from an external control device to control the drive unit 103 and motor 204. Based on the control signals, the control unit 205 controls the operation of the drive unit 103 to rotate the shaft 201, and operates the motor 204 to adjust the tilt of the printing object 202 in the holder 104.

Next, the structure of the holding unit 104 will be described with reference to Figure 3 and Figures 4(A) to (E). Figure 3 is a perspective view showing the appearance of the holding unit 104. Figure 4(A) is a plan view of the holding unit 104 seen from above. Figures 4(B) to (E) are side views of the holding unit 104, respectively.

Each holding unit 104 has a base 301. The bottom surface of the base 301 determines the size that each holding unit 104 occupies on the holding substrate 102. In addition, a recess 301A is formed in the bottom surface of the base, which is used to fix it on the holding substrate 102.

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 contacts a second conversion member 303 attached to the shaft 203. Because the second conversion member 303 rotates together with the shaft 203, the rotation of the shaft 201 can be transmitted to the perpendicular 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.

At this time, the rotation of the shaft 201 occurs in the YZ plane, but this can be converted to 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 object 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 object 202, and can detachably hold the printing object 202. Therefore, by rotating the first holding member 304 about the shaft 203 as an axis, the printing object 202 can be rotated in the XZ plane.

Although hidden by member 301B of base 301 in Figure 3, as particularly shown in Figure 4 (B), motor 204 is disposed within holding portion 104, and shaft 307 is the shaft of motor 204. 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. A space 314 is formed within base 301 so that this rotation is not impeded.

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.

Shaft 309 is attached to first holding member 304 and functions as the rotation axis of second transmission member 310, and does not rotate with second transmission member 310. Therefore, the rotation of second transmission member 310 does not affect first holding member 304. Next, shaft 311 is a shaft that passes through 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 rotational 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.

In this embodiment, shaft 203 serves as the X-axis rotation axis, while shaft 311, which is perpendicular to shaft 203, serves as the Y-axis rotation axis. Positioning the X- and Y-axis rotation axes as close as possible to the third holding member 306 increases the precision 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 each rotation axis. To achieve this configuration, motor 204 is installed below shaft 203 and farther from the third holding member 306 and the printing object 202. This is because if motor 204 were positioned higher, it would occupy a certain space and prevent the shaft from penetrating, causing shaft 203 to be positioned farther away from the third holding member 306, etc. Additionally, 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 around shaft 203. Furthermore, by placing shaft 203 below shaft 311, there is no longer any restriction from shaft 203, ensuring a wide range of rotation for second holding member 305 around shaft 311.

Next, the structure of the lifting device 105 will be described with reference to Figure 5. Figure 5 is a diagram showing an example of the appearance of the lifting device 105 corresponding to an embodiment of the invention. The lifting device 105 has a main pulley 207, lifting unit 206, guide pulley 208, and belt 209 arranged on a substrate 501. The operation of these components is as described in relation to Figure 2. Furthermore, 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 Figure 6.

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

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 by the holding device 100, and a control device 120 which controls the operation of the holding device 100 and the printer 110.

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 tilt and height of the printing object 202, and provides image information corresponding to the state of the printing object 202 to the printer 110 to perform printing. Printing can be performed in multiple batches, with the tilt and height of the printing object 202 being changed each time printing is performed. Once all multiple printing batches are complete, the printing object 202 is returned to its initial position, and multiple printing objects 202 can be collected together using a set tray.

Next, with reference to Figure 6(B), the hardware configuration of the control device 120 corresponding to an embodiment of the invention will be described. In Figure 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 the temporary storage of information, files, etc. required for program execution in RAM 602. It controls the operation of the holding device 100 and printer 110 via an interface (I/F) 608 to perform printing processing corresponding to this embodiment. The processing in Figure 9, described below, is also realized by the CPU 600 controlling the entire device by executing the corresponding processing program.

ROM 601 stores various data, such as basic I/O programs and application programs that execute specified processes. RAM 602 temporarily stores various data and functions as the CPU 600's main memory, work area, etc.

External storage drive 603 is an external storage drive that provides access to storage media, and can load programs and other data stored on media (storage media) 604 into the computer system. Media 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, or memory stick. In this embodiment, external storage device 605 is an HD (hard disk) that functions as a large-capacity memory. Application programs, an OS, control programs, related programs, and other data are stored on HD 605. A non-volatile storage device such as flash (registered trademark) memory may also be used instead of a hard disk.

The instruction input device 606 may be a keyboard, pointing device (such as a mouse), or touch panel. The output device 607 outputs commands input from the instruction input device 606 and the control device 120's corresponding response output. The output device 607 may include a display, speaker, 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 acts as an intermediary for 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 may include both a wireless communication module and a wired communication module.

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

When the printing object 202 is oriented as shown in Figure 7(A), the left side of the doll's mask, which is the printing object, is positioned at the top. 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 the eyes 701 and eyebrows 702 are positioned so that they are located approximately in the center of the printed image (especially in the horizontal direction).

When the printing object 202 is oriented as 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 printed on the printing object 202 corresponds to the doll's lips, as shown in image 710. Here, the lips 711 are positioned so that they are located approximately in the center of the printed image. In image 710, the skin color around the lips has been omitted, but the skin color portion may also be printed at the same time.

When the printing object 202 is oriented as shown in Figure 7(C), the right side of the doll's mask, which is the printing object, is positioned at the top. 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 the eyes 721 and eyebrows 722 are positioned so that they are located approximately in the center of the printed image (especially in the horizontal direction).

The printing object 202 held by the holding device 100 corresponding to this embodiment is fixed at a predetermined angle and height, and then inkjet printing is performed on its surface by the printer 110. As shown in Figure 7(D), while the print head 730 is scanned in the scanning direction indicated by arrow 731, it ejects ink onto the printing object 202 located directly below to perform printing. 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.

The holding device 100 corresponding to this embodiment adjusts the tilt and height so that the distance d between the printing surface of the printing object 202 held in each holding section 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, for example, between 0.1 mm and 3 mm. When D = 0.1 mm, this represents the shortest distance between the print head and the surface of the printing object 202, and is adjusted so that the distance between the print head and the most protruding part of the surface of the printing object during printing is 0.1 mm.

When printing a facial image like that shown in Figure 7(A) on a doll's mask, which is the printing object 202, the tilt and height of the printing object 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 will be protruding from the surface of the printing object 202, and the eyes will be recessed (concave). Therefore, the tilt and height of the printing object 202 are adjusted so that the distance d between the print head 730 and the recessed part of the eyes is within 3 mm. In this case, the eyebrows only need to be located within a range of 0.1 mm to 3 mm. Regarding the surrounding skin-colored area, if the eyebrows are located farther from the print head than 3 mm due to the unique unevenness of the face, they may be included in a separate image and their tilt and height adjusted before printing. Furthermore, if the skin-colored area can be printed with ink droplets and some blurring or misalignment is acceptable, the skin-colored area 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 Figure 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 tilt and height of the printing object 202 are adjusted so that the other parts are within a distance range of 3 mm.

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

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. ID 801 registers identification information for identifying the printing object 202. When the printing object 202 is identified, the control device 120 can select the 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.

The print image 802 is registered as the 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, so in table 800, three images are registered in association with one ID. For example, for a print object 202 with ID 801 of 0001, three images, imageLeft0001, imageTop0001, and imageRight0001, are associated. However, embodiments of the invention are not limited to this, and a greater or lesser number of images may be assigned.

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. For example, information for rotating from a reset position to a desired angle in the X axis direction can be registered as this control information. A different value is registered in the rotation angle (X axis) 803 for each print image 802. Based on this control information, the control unit 205 can drive the drive unit 103 to rotate the shaft 203.

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. For example, information for rotating from a reset position to a desired angle in the Y axis direction can be registered as this control information. A different value is also registered in the rotation angle (Y axis) 804 for each print image 802. Based on this control information, the control unit 205 can drive the motor 204 to rotate the shaft 311.

In the lifting distance (Z axis) 805, control information is registered for adjusting the height of the printing object 202 using the lifting device 105. For example, information for raising or lowering the object 202 from a reset position to a desired position in the Z axis direction can be registered as this control information. A different value is also registered in the lifting distance (Z axis) 805 for each print image 802. Based on this control information, the control unit 205 can drive the main pulley 207 to raise or lower the lifting unit 206.

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

First, in S901, an initialization operation is performed. The initialization operation includes, for example, resetting the tilt 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 resetting the operation of the printer 110. The control device 120 sends a reset signal to the holding device 100 and the printer 110 to perform the initialization operation.

Next, in S902, the print object 202 to be printed in this printing system is selected. This selection involves the user selecting the type of print object 202 on the control device 120, and the value of ID 801 is identified in accordance with the selection. In the following S903, based on the identified value of ID 801, the corresponding print image and control information (each of the registration information 803 to 805 in Figure 8) are obtained from table 800.

Next, in S904, one of the acquired print images is selected and sent to the printer 110. In S905, control information corresponding to the selected image is sent to the holding device 100 and operated, thereby changing the tilt of the holding unit 104 and the height of the holding substrate 102 to match the conditions corresponding to the selected image.

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).

Next, in S906, the printer 110 is controlled to print the selected images. When printing is complete, in S907, it is determined whether all of the images to be printed for the selected print object have been printed. If it is determined that all 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.

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 print object in table 800 have been printed.

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, embodiments of the invention are not limited to this. For example, after selecting a first print image and adjusting the tilt of the holding unit 104 and the height of the holding substrate 102 to the corresponding tilt and height and printing, 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.

In this case, table 800 registers the rotation angles 803, 804 and lift distance 805 from the reset position for the first print image 802 to be printed. For subsequent print images 802, however, the rotation angles 803, 804 and lift distance 805 for adjusting the tilt of the holding unit 104 and the height of the holding substrate 102 for the current print image, based on the tilt of the holding unit 104 and the height of the holding substrate 102 for the previous print image, are registered. For example, suppose the XL1 value of the rotation angle 803 for imageLeft0001 when a reset operation is performed is plus 15 degrees, and the XT1 value of the rotation angle 803 for imageTop0001 is minus 1 degree. In this case, if a reset operation is not performed, after imageLeft0001 is printed, a minus 16 degree rotation 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, it is possible to omit the reset operation even when switching print images 802 and printing them.

In addition, while the above-described embodiment does not specifically specify the order of printing, the order may be selected so that the side of the printing object 202 is printed first, followed by the front. Alternatively, the order may be selected so that the front of the printing object 202 is printed first, followed by the side. In the example shown in FIG. 7 , printing can be performed first under the conditions shown in FIGS. 7(A) and (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 object 202 from its left-facing state shown in FIG. 7(A) to its right-facing state shown in FIG. 7(C), and further to its front-facing up state shown in FIG. 7(B). Furthermore, when transitioning to a 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, fine adjustments can be made from the reset position to adjust the tilt to match the front side printing, further improving accuracy.

As described above, this embodiment allows for appropriate printing on uneven surfaces of printing targets. In particular, with the above configuration, when simultaneously printing on multiple printing targets with uneven, non-uniform surfaces, the angles of the multiple printing targets can be accurately adjusted simultaneously so that the virtual plane on the printing target faces the print head properly, and the change in distance from the print head falls within a certain range.
