Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. (First Structural Example) Fig. 1 is a view showing a typical view of a screen printing method. This screen printing method is for forming a printed layer 15 on the surface 13 to be printed having a base member 11 having a curved shape, and generally comprises the following steps. First, an endless belt-like screen 17 on which a printed pattern is formed is driven to rotate in the peripheral direction of one of the screens 17. The base member 11 and the screen 17 are moved relative to each other in accordance with the peripheral velocity of the screen 17 that is rotationally driven. A doctor blade 19 is disposed on the inner peripheral side of the screen in the belt width direction of the screen 17 (perpendicular to the direction of one of the sheets of Fig. 1). When the doctor blade 19 is scraped on the base member 11, the doctor blade 19 transfers a printing material 21 placed on the screen 17 to the surface 13 to be printed to form the printing layer 15. The above is a printing layer forming step. In addition to the printing layer forming step mentioned above, this screen printing method also includes an angle of attack holding step. In the angle of attack holding step, at least one of the base member 11 and the blade 19 is swung in accordance with the curved shape of the base member 11. Due to this swing, the angle of attack q between the doctor blade 19 and the base member 11 is maintained at a specific angle. Incidentally, the "angle of attack" referred to herein means a tangent at a contact point formed at a position where the edge of the blade 19 is in contact with the base member 11 via the screen 17, and a surface of the blade 19 is in the screen 17 Among the angles between the virtual lines of one of the doctor blades 19 formed at the upstream side of the rotational drive in the peripheral direction and including the edge of the doctor blade 19, the rotation in the peripheral direction drives the corner on the front side. The relative movement between the base member 11 and the screen 17 provides one of the operations of moving the base member in the direction of movement of the perimeter of the screen 17. Further, the printing material 21 is supplied on the peripheral surface inside the screen 17 before printing. Also, the printed material 21 may be supplied at an arbitrary timing after the start of printing. Next, a screen printing apparatus for carrying out one of the above screen printing methods will be described. Figure 2 is a side elevational view of one of the first structural examples of a screen printing apparatus. One screen printing apparatus 100 of this structural example comprises: a loop-shaped screen plate 17 disposed above the base member 11 and having a printed pattern formed thereon; a scraper 19 for placing on the screen 17 The upper printing material is transferred to the surface 13 to be printed of the base member 11 to form a printing layer 15; and a screen rotation driving portion 59 for driving the screen 17 to rotate in one of its peripheral directions. Further, the screen printing apparatus 100 includes: a relative movement driving mechanism for moving the base member 11 and the screen 17 relative to each other and scraping on the base member 11 with a doctor blade 19; and a swing driving mechanism for use The angle of attack between the doctor blade 19 and the base member 11 is maintained at a specific angle, and details thereof will be discussed later. The doctor blade 19 is not particularly limited as long as it can form the printing layer 15 by transferring the printing material to the surface to be printed 13 of the base member via the screen plate 17. As for the material of the blade 19, it is not limited to the use of a conventional blade made of a rubber, but a blade made of another resin and a blade made of metal can also be used. A support substrate 25 is fixed to a substrate 23, and a susceptor holder 31 is supported on the support substrate 25. The susceptor holder 31 supports a base portion 35 for fixing the base member 11 and a drive portion 27 constituting a portion of the relative movement drive mechanism and the oscillating drive mechanism in the long axis direction of the susceptor holder 31 (in FIG. 2 Drive in the horizontal direction). Therefore, the screen 17 rolls on the surface 13 to be printed on the base member 11 on the base 35, thereby performing printing. The support base 25 includes a pair of cam followers 29 on either side thereof. The pair of cam followers 29 are rotatably supported on the support base 25. The cam follower 29 supports the base holder 31 so as to reciprocate in the horizontal direction of FIG. 2 (i.e., the long axis direction of the base holder 31). A pair of cam grooves 33 extend in the longitudinal direction of the susceptor holder 31 on both side surfaces (the front surface and the rear surface of the sheet of FIG. 2) in the short-axis direction of the susceptor holder 31. In the illustrated example, only the cam groove 33 on the front surface side is shown, but a cam groove (not shown) also extends on the rear surface side of the cam groove 33. These cam grooves 33 are formed as curved grooves extending along the surface 13 to be printed of the base member 11. The cam follower 29 and the cam groove 33 constitute a front cam as a part of the swing drive mechanism 43. In the front cam, one of the grooves having a profile curve recessed in the thickness direction of the screen is formed in the side surface (base holder 31) of the screen while the cam follower 29 (which is a driver) Fitted into this groove. According to this cam mechanism, since the cam follower 29 serving as a driver moves while being fitted into the cam groove 33, the power transmission to the susceptor holder 31 can be clearly performed, whereby the susceptor holder 31 is realized. High speed and high precision motion. In the base member 11 of this structural example, the surface to be printed 13 has a curved shape. The curved shape of the surface to be printed 13 provides a concave concave surface. More specifically, the concave surface of the surface to be printed 13 is structured such that its central portion provides a horizontal surface and its sides provide an upwardly curved inclined surface. A height difference between the horizontal surface and the inclined surface provides D. Although the cam groove 33 is engaged with the cam follower 29, the base holder 31 can be driven by the driving portion 27. Therefore, the base member 11 can reciprocate in the left-right direction of FIG. 2 with respect to the horizontal surface and the inclined surface mentioned above with respect to the support base 25. The susceptor 35 fixed to the upper surface of the susceptor holder 31 is formed of a material (for example, carbon or resin) which is softer than the base member 11. As the resin, for example, Bakelite (registered trademark), PEEK (registered trademark), vinyl chloride, and POM (DURACON: registered trademark) can be used. These resins may also be subjected to a surface treatment by one of the conductive films or the like for providing conductivity or a mixture of carbon or the like. Further, the susceptor 35 has one surface having one shape (i.e., a concave shape) substantially identical to the surface 13 to be printed of the base member 11. The base 35 is fastened to the base holder 31 by bolts 37. The susceptor 35 preferably has a volume resistivity of at least one of its surfaces, and the volume resistivity is 10 ⁹ Wm or smaller and better from 10 ⁷ Wm to 10 ⁸ Wm. This suppresses static electricity which occurs during printing, thereby enhancing the release of the screen 17 from the surface to be printed 13. In addition, since the printed material 21 can be well released, the screen is free from contamination, thereby achieving enhanced printing accuracy. Moreover, since the generation of static electricity is reduced, foreign matter (such as dust) is not attracted, thereby realizing the formation of the printed layer 15 of excellent quality. A plurality of holes are opened in the upper surface of the base 35. The holes are connected to a vacuum device (not shown) whereby the outside air is drawn in from the holes. The base member 11 placed on the upper surface of the base 35 is vacuum-attracted to the base 35 by suction of the holes. Here, the base 35 has a groove (not shown) having the same shape as the base member 11 while the base member 11 is fitted into this groove. A relative movement drive mechanism 41 is provided between the support base 25 and the base holder 31 using a belt or a chain (not shown). The relative movement drive mechanism 41 causes the susceptor holder 31 to move relative to the screen 17 in accordance with the peripheral speed of the screen 17 that is rotationally driven. That is, the relative movement drive mechanism 41 drives the base holder 31 in the rotational movement direction of the screen 17 at the contact position of the blade 19 with the screen 17. Therefore, the base member 11 is moved through the base 35 with respect to the screen 17 which is rotated at a fixed position, whereby the blade 19 is swept on the base member 11. At the same time, the cam groove 33 and the cam follower 29 constitute a swing drive mechanism 43. The swing drive mechanism 43 swings at least one of the base member 11 and the scraper 19 around the center of curvature of the curved shape of the base member 11 in accordance with the curved shape. In this structural example, the swing drive mechanism 43 provides a front cam and swings the base member 11. Due to the front cam being constituted by the cam groove 33 and the cam follower 29, the base member 11 is swingable about the center of curvature of the base member 11. This oscillation achieves maintaining an angle of attack q between the doctor blade 19 and the base member 11 at a specific angle. In the base member 11 of this structural example, the center of curvature of the base member 11 and the center of curvature of the cam groove 33 coincide with each other in the region of the curved groove formed on both lateral sides of the cam groove 33, and the base 35 and the base holder 31 swing around the center of curvature. Next, the supporting mechanism of the screen plate 17 will be described. A screen support frame 45 is erected on the support base 25. A screen support bracket 47 is mounted on the screen support frame 45 to rotatably support a cylindrical screen 17. Figure 3 is a cross-sectional view taken along line AA shown in Figure 2. The screen support bracket 47 includes a pair of bracket side plates 53 that are respectively suspended from the two ends of a bracket body 51. The pair of bracket side plates 53 fix the two ends of a shaft member 55. The shaft member 55 rotatably supports a screen unit 56 having a cylindrical screen 17 between the pair of bracket side plates 53. The screen unit 56 includes a pair of cylindrical screen frames 57 on which the rolling bearings 58 for supporting the shaft members 55 are mounted on the radially inner side, and on which the cylindrical screen plates 17 are mounted on the radially outer side. The pair of screen frames 57 and screens 17 are joined together by a pillar portion (not shown) and rotatably supported on the shaft member 55 to have low friction. A biasing member 49, such as a spring, is provided between the screen support frame 45 and the screen support bracket 47. The biasing member 49 can bias the screen support bracket 47 toward the base 35 side. The screen unit 56 is disposed above the base member 11. The screen 17 has a printed pattern, and both ends of the longitudinal direction of the strip screen are connected to each other to form a loop-shaped screen having a circular cross section. As the screen 17, it is preferred to use a nickel-plated stainless steel screen. The nickel-plated stainless steel screen has a high rigidity and is difficult to deform as compared with a net made of a common resin (for example, Tetoron (registered trademark)). Therefore, the cylindrical shape is satisfactorily maintained, and thus distortion after printing can be prevented. The screen plate 17 is driven by the screen rotation driving portion 59 to rotate about the shaft member 55. The screen rotating drive portion 59 includes a screen drive motor 61 and a rotary transmission member 63 such as a gear or a friction roller. The screen drive motor 61 is fixed to the screen support bracket 47 such that its drive shaft member is disposed parallel to the shaft member 55. The rotation transmission member 63 is fixed to the drive shaft member of the screen drive motor 61, and the rotation of the screen drive motor 61 is transmitted to the screen frame 57 by the rotation transmission member 63. Therefore, the screen rotation driving portion 59 drives the screen unit 56 to rotate, thereby rotating the screen 17 in the peripheral direction at the periphery. The doctor blade 19 is disposed on the inner peripheral side of the screen in the belt width direction of the screen 17. The doctor blade 19 has a blade base portion 65 fixed to one of the shaft members 55, and the blade edge portion 67 of the blade 19 is in contact with the inner peripheral surface of the screen plate 17. The doctor blade 19 transfers the printing material 21 (see Fig. 1) to the surface 13 to be printed of the base member 11 which is fitted into the holding groove 39 of the susceptor 35 and is vacuum-absorbed, thereby forming a printing layer. The screen 17 is placed on the screen frame 57 to have a specific tension. The doctor blade 19 (where the blade edge portion 67 presses the screen 17 outward in the radial direction) pushes the printing material 21 onto the surface 13 to be printed according to the printing pattern of the screen 17, whereby a printing layer is formed on the surface 13 to be printed . Here, the screen printing apparatus 100 includes a printing material supply portion (not shown) for supplying the printing material 21 to one of the inner peripheral surfaces of the screen 17. The printing material supply portion makes it possible to regularly supply the printing material 21 to the inner peripheral surface side of the screen 17 according to the printing material 21 by the consumption of printing. Next, the operation of the screen printing apparatus 100 of the above structure will be described. Fig. 4 is an explanatory view showing an operation in a screen printing method in which printing steps on a surface to be printed having a curved shape are sequentially illustrated in (A) to (C). In the screen printing method of this structural example, as shown in FIG. 4(A), the ring-shaped screen plate 17 is rotationally driven in a counterclockwise direction by, for example, a screen rotation driving portion (not shown). . The relative movement drive mechanism causes the base member 11 to move in synchronism with the rotational drive of the screen 17 (i.e., according to the peripheral rate of the screen 17). In this structural example, the screen 17 is supported at a fixed position while the base member 11 is driven from the left side to the right side through the base 35, as shown in (B) and (C) of FIG. . Further, the oscillating drive mechanism causes the susceptor 35 to oscillate around the center of curvature of the curved shape of the base member 11 following the cam groove 33 extending along the curved shape of the base member 11. Therefore, as shown in FIG. 5, at a pressure point of the blade 19 on the base member 11 (the same position as the contact point between the blade 19 and the screen 17), the screen 17 is always at each contact point. A specific angle of attack q is in contact with the surface 13 to be printed. Here, any other structural example different from the structural example may be employed as long as the blade 19 can be swingably supported with respect to the center of curvature of the curved surface shape of the screen 17 to be printed, and the angle of attack q can be set to one. You can do it at a specific angle. Therefore, it is possible to achieve a stable ejection pressure of one of the printing materials 21 and to provide high-precision transfer (printing) which suppresses bleeding or the like. As described above, the angle of attack q means that at an angle formed on the front side in the peripheral direction of the rotational driving of the screen, among the angles formed between the blade 19 and the base member 11. The angle of attack q is preferably 90 or less and more preferably 80 or less. Also, the angle of attack q is preferably 50 or more and more preferably 60 or more. Within this range, the screen release is excellent, thereby achieving high-precision printing that suppresses bleeding or the like. Here, the angle of attack q in a curved shape means that an angle formed between the tangential line of the base member 11 at the pressure point of the blade 19 and the blade 19 is formed. Further, after the screen 17 and the surface 13 to be printed are in vertical contact with each other, when the screen 17 is released, the screen 17 and the surface 13 to be printed do not rub against each other near their contact points. That is, at the point of contact between the screen 17 and the surface 13 to be printed, the sheets do not slide on each other. Therefore, the printing material 21 pushed out from the inner peripheral surface of the screen 17 by the doctor blade 19 to the surface to be printed 13 can be transferred to the surface 13 to be printed in an accurate shape in accordance with the printing pattern of the screen 17. In this case, when the screen 17 is formed into a ring shape and pressed against the base member 11, the screen 17 is moved relative to the base member 11. Therefore, the screen 17 can even have a to-be-printed surface 13 having a bending depth equal to or greater than one of the conventional flat screens, or a standby having a projection and a recess. The printing surface 13 is in proper contact. Therefore, printing can be obtained under appropriate printing conditions. Further, in this screen printing method, the base member 11 is moved relative to the screen 17 which is rotationally driven at a fixed position. In this configuration, the relative movement drive mechanism 41 can be provided only on the side of the base member, thereby simplifying the structure of the screen printing apparatus 100. Further, in this screen printing method, the printing material supply portion is provided to maintain the amount of the printing material 21 on the inner peripheral side of the screen at a specific amount. This can suppress variations in the amount of ejection of the printed material 21, thereby achieving stable printing. Further, a plurality of base members 11 can be continuously printed, thereby realizing mass production of the base member 11 having a stable printing quality. Here, the base member 11 is preferably made of a transparent glass. This glass-made base member 11 can be adapted for internal working of transportation devices such as vehicles, trains, ships, and airplanes. More specifically, the base member 11 can be applied to an instrument panel of a vehicle, a head-up display (HUD), an instrument panel, a center console, a shift knob, and the like. This provides internal parts with high design quality and excellent feel for enhanced internal design of the transport device. Further, as the base member 11, one of glass, ceramic, resin, wood, metal or the like may be used. Specifically, as the glass, in addition to a colorless and transparent amorphous glass, a crystallized glass, a colored glass, and the like can be mentioned. Further, as the glass, an inorganic glass is preferable. In the case of using an inorganic glass, high hardness can be achieved and transparency is less likely to be lowered as compared with the case of an organic glass such as an acrylic resin or a polycarbonate. Therefore, durability can be enhanced. As the glass, for example, an alkali-free glass, soda lime glass, soda lime silicate glass, aluminosilicate glass, borosilicate glass, lithium aluminum silicate glass or borosilicate glass can be used. It is preferred to use an aluminosilicate glass which can be easily given a large stress by a strengthening treatment even in the case of a thin thickness and can obtain a glass having a high strength from one glass even in the case of a thin thickness. However, the glass is not limited to this. The glass composition is not particularly limited, but a specific example thereof includes glass containing one of the following as a composition (in mole %): 50% to 80% of SiO ₂ , 0.1% to 25% Al ₂ O ₃ 3% to 30% of Li ₂ O+Na ₂ O+K ₂ O, 0% to 25% of MgO, 0% to 25% of CaO and 0% to 5% of ZrO ₂ . More specifically, the following glass compositions can be mentioned. Incidentally, for example, "containing 0% to 25% of MgO" means that MgO is not essential but may contain up to 25%. The glass of (i) belongs to soda-calcium silicate glass, and the glasses of (ii) and (iii) belong to aluminosilicate glass. (i) Glass containing one of the following components as a composition (in mole %): 63% to 73% SiO ₂ , 0.1% to 5.2% Al ₂ O ₃ 10% to 16% Na ₂ O, 0% to 1.5% of K ₂ O, 0% to 5% of Li ₂ O, 5% to 13% MgO and 4% to 10% CaO. (ii) Glass containing one of the following components as a composition (in mole %): 50% to 74% SiO ₂ 1% to 10% Al ₂ O ₃ 6% to 14% Na ₂ O, 3% to 11% of K ₂ O, 0% to 5% of Li ₂ O, 2% to 15% MgO, 0% to 6% CaO and 0% to 5% ZrO ₂ , SiO ₂ And Al ₂ O ₃ The sum of the contents is 75% or less, Na ₂ O and K ₂ The sum of the contents of O is 12% to 25%, and the sum of the contents of MgO and CaO is 7% to 15%. (iii) Glass containing one of the following components as a composition (in mole %): 68% to 80% SiO ₂ 4% to 10% Al ₂ O ₃ 5% to 15% Na ₂ O, 0% to 1% of K ₂ O, 0% to 5% of Li ₂ O, 4% to 15% MgO and 0% to 1% ZrO ₂ . (iv) Glass containing one of the following components as a composition (in mole %): 67% to 75% SiO ₂ 0% to 4% Al ₂ O ₃ 7% to 15% Na ₂ O, 1% to 9% of K ₂ O, 0% to 5% of Li ₂ O, 6% to 14% MgO and 0% to 1.5% ZrO ₂ , SiO ₂ And Al ₂ O ₃ The sum of the contents is 71% to 75%, Na ₂ O and K ₂ The sum of the contents of O is from 12% to 20%, and the content of CaO is less than 1% (in the case where it is contained). Here, the relative moving drive mechanism and the swing drive mechanism mentioned above are merely examples and are not limiting. For example, as the oscillating drive mechanism, a platform including one of the mechanisms for driving at least one of the following: an X-axis shaft member; a Y-axis shaft member that is perpendicular to each other; and a Z-axis shaft member may be used. A vertical shaft member; and a swinging shaft member to be swung about an axis parallel to the X-axis or the Y-axis. (Modified Example of First Structural Example) Fig. 6 is a side view of one of the screen printing apparatuses according to one of the first structural examples. One of the modified examples of the screen printing apparatus 100A differs from the screen printing apparatus 100 mentioned above by a base holder 69, a base 71, and a cam groove 73. The remaining components are similar to the screen printing apparatus 100. The base member 11 includes a projection and a recess in the surface 13 to be printed. The cam groove 73 is formed in accordance with the curved shape of the surface 13 to be printed. Therefore, the susceptor holder 69 and the susceptor 71 are also formed in the shape of the cam groove 73. According to the screen printing apparatus 100A, the susceptor holder 69 and the susceptor 71 are driven along the cam groove 73, and the angle of attack of the blade 19 and the base member 11 is maintained at a specific angle, thereby realizing the inclusion of the projection and the recess. Printing of the substrate member 11 on the surface 13 to be printed. As the base member 11, one member having one curved shape in one direction or in two or more directions may be used. According to the screen printing described above, even in the base member whose surface to be printed 13 has a bending depth equal to or larger than one of the press-in limit of one of the screens, or the surface to be printed 13 contains a protrusion In the base member of both the portion and the recess, appropriate printing can still be performed on the surface 13 to be printed. Here, the thickness of the maximum width of the curved shape is formed by the concave portion and the protruding portion of the base member 11 (in the side view of the base member 11, the difference between the highest portion and the lowest portion of the base member 11 in the height direction) It is preferably 5 mm or more and 300 mm or less, more preferably 10 mm or more and 200 mm or less, and further preferably 10 mm or more and 50 mm or less. Even in the base member 11 having such a maximum thickness of the curved shape, a printing layer 15 can be simply formed on the entire surface of the concave portion and the protruding portion. In the base member 11 having a curved shape, in the case where the curved shape provides a concave portion, the radius of curvature of the concave portion is preferably 200 mm or more and 5000 mm or less, and more preferably 300 mm or more and 3000. Mm or smaller. As described above, according to this structural example, in the screen printing apparatus 100 and the screen printing apparatus 100A, respectively, various base members 11 such as a base member having a concave curved shape glass as shown in FIG. 7A can be achieved. 11, and printing on the base member 11) having a curved-shaped glass including a recess and a projection as shown in Fig. 7B. In addition, printing can be achieved even on a S-shaped curved glass having a more complex recess and protrusion as shown in Figure 7C. (Second Structural Example) Next, a screen printing apparatus according to a second structural example will be described. Figure 8 is a side elevational view of a main portion of a screen printing apparatus according to a second structural example. In the following structural examples and modified examples, the same members and portions as those shown in FIGS. 1 to 7 are given the same names and thus repeated descriptions of the same are omitted or simplified. In the screen printing apparatus 200 of the second structural example, the base member 11 is immovably fixed. The relative movement drive mechanism 75 of the screen printing apparatus 200 moves the screen 17 and the blade 19 along the curved shape of the base member 11. In this case, the relative movement drive mechanism 75 can use a known XZ platform mechanism that uses a motor or the like as a drive source and achieves the horizontal direction (X direction) and the vertical direction in FIG. 8 ( Movement in the Z direction). The relative movement drive mechanism 75 includes a screen support bracket 77 for rotatably supporting a cylindrical screen 17 similar to one of the cylindrical screens mentioned above. The screen support bracket 77 is movable in the X direction and the Z direction. The screen support bracket 77 includes a screen support frame 79 having a vertical cross section of an inverted U-shape in the axial direction of the shaft member 55. The screen supporting frame 79 includes a roller 81 that is freely rotatable in one of the pair of lower end portions on the opening side that provides the U-shaped shape, respectively. The roller 81 can be in rolling contact with the surface of the base member to change the direction (tilt) of the screen support frame 79 and the base member 11. That is, the screen supporting frame 79 serves as a swing driving mechanism that maintains the angle of attack θ of the blade 19 and the base member 11 at a specific angle. A sliding member 83 is slidably disposed inside the screen supporting frame 79. The sliding member 83 supports the shaft member 55 of the screen plate 17 and is biased toward the base member 11 by a biasing member 85 such as a spring. Therefore, the screen 17 and the blade 19 are pressed against the base member 11. Figure 9A is a side elevational view of the screen printing apparatus according to the second structural example as it moves on a plane to be printed. Fig. 9B is a side view showing a screen printing apparatus according to a second structural example when it is moved on a surface to be printed having a curved shape. According to the screen printing apparatus 200, the relative movement between the base member 11 and the screen 17 provides operation for moving the screen 17 and the blade 19 along the curved shape of the base member 11. That is, when driven by the relative movement driving mechanism, the screen supporting bracket 77 moves from the state in which the plane to be printed 13 is provided with a plane of Fig. 9A to the state in Fig. 9B in which the surface to be printed 13 provides a curved shape. Therefore, the screen supporting frame 79 is driven to rotate (swing) forward with the shaft member 55 of the screen 17 in the moving direction. Therefore, the screen supporting frame 79 is inclined in accordance with the inclination of the base member 11, thereby changing the direction of the blade 19. This oscillating operation maintains the angle of attack q of the doctor blade 19 and the base member 11 at a specific angle. According to the screen printing apparatus 200, the screen 17 and the blade 19 disposed on the inner peripheral side of the screen are integrally moved along the curved shape of the base member 11 by the relative movement drive mechanism and the swing drive mechanism. This structural example is particularly effective in the case where the base member 11 has a size that is difficult to move or has a strength that is difficult to move. (Third Structure Example) Next, a screen printing apparatus according to a third structural example will be described. Figure 10 is a side elevational view of one of the main parts of a screen printing apparatus according to a third structural example. In the screen printing apparatus 300 of the third structural example, a ring-shaped screen plate 17 extends over a plurality of screen rollers 87 and is rotationally driven. In the screen printing apparatus 300, the endless belt-like screen 17 extends over a plurality of (four in the illustrated example) screen rollers 87. The screen 17 thus extended is rotationally driven by a screen rotary drive portion such as a motor (not shown). A doctor blade 19 (similar to the structural example mentioned above) is disposed on the inner peripheral side of the screen plate 17. According to the screen printing apparatus 300 having the above-mentioned structure, it is possible to print on the surface to be printed of the base member 11 at a time equal to or greater than 2 pr (the length of the circumference of the cylindrical screen 17) (r-shaped cylindrical shape) One of the lengths of the radius of the shape) is printed. The use of a long ring screen 17 enables a great expansion of the range of applications that can be applied to printing. (Modified Example of Third Structural Example) Fig. 11 is a side view showing one of main parts of a screen printing apparatus according to one of the third structural examples. Here, one of the virtual lines of the halftone 17 in the case where one of the dotted circles has the cylindrical shape mentioned above is shown in FIG. The screen printing apparatus 300A of the modified example of the third structural example has a small distance between one of the pair of doctor blades 19 and the screen cylinder 87 as compared with the screen printing apparatus 300 of FIG. This achieves a more tapered shape of the portion of the screen 17 that is present in the edge portion of the doctor blade 19. In the case of the base member 11 having a curved shape, in the case where the curved shape provides a concave portion, the printing on the base member having a small radius of curvature is realized using the screen printing device of the third structural example. The lower limit of the radius of curvature is preferably 50 mm and more preferably 60 mm. According to the screen printing apparatus 300A, after the wiping position of the blade 19, the angle between the screen 17 and the surface of the base member is larger than the angle in the case where the screen 17 has a cylindrical shape. Therefore, the release of the screen from the base member 11 is enhanced. This achieves high precision printing without disturbing the shape of the printed pattern. In particular, in the case where one of the base members 11 has a concave surface having a small radius of curvature, the printing system is difficult because the area of the base member 11 pressed by the blade 19 is narrow. Even in this case, the screen printing apparatus 300A can achieve sufficient printing on one of the narrow areas, since the portion of the screen 17 that can exist before and after the blade 19 can be configured to an acute angle. Here, both the screen printing apparatus 300 and the screen printing apparatus 300A are structured such that the base member 11 is movable. However, similar to the screen printing apparatus 200, the screen 17 and the blade 19 can be moved relative to the fixed base member 11. As described above, according to the screen printing apparatuses 100, 100A, 200, 300, and 300A, it is possible to achieve an object to be printed on an object having a bending depth equal to or greater than one of the pressing limit amounts of one of the conventional screens. And printing on the surface to be printed of an object comprising both a projection and a recess. Further, the base member printed by the screen printing method described above provides a uniquely shaped print which is an excellent product with enhanced design and appearance.
