The substrate S is stopped by coming into contact with the substrate S that has been moved.

The storage unit 60 is disposed at the rear of the main body of the printing apparatus 20, and is a mechanism for storing members to be replaced (to be carried in and to be carried out) when automatically replacing the screen mask M and the substrate support member 70. The storage unit 60 includes a storage box with an open front and a conveyor elevating section 62 that raises and lowers the storage box. Inside the storage box, a pair of transport conveyors 61 that transport the placed objects in the front-rear direction are arranged in a plurality of stages (four stages in this embodiment) vertically. Screen masks M to be carried into the mask working section 26 and substrate support members 70 to be carried into the first and second substrate fixing parts 30 and 40 are attached to three of the four stages of conveyors 61. A transport jig 80 for attaching the substrate support member 70 to be carried out from the first and second substrate fixing parts 30 and 40 is stored in advance by the operator. Further, the remaining one stage of the conveyor 61 is left open so that it can accommodate the screen mask M to be carried out from the mask working section 26. This storage section 60 is constructed by making the top surface of one of the transport conveyors 61 the same height as the top surface of the transport rail 29 by the conveyor elevating part 62, and operating the transport conveyor 61 in that state. The members placed thereon are carried into the mask working section 26, and the members are carried out from the mask working section 26.

The transport jig 80 is a member that allows the substrate support member 70 to be transported using the transport conveyor 61 or the transport rod 25a. As shown in FIG. 5, the transport jig 80 has first to fourth protrusion holding parts 81 to 84 arranged inside a frame 85 in this order from the rear to the front. The first to fourth protrusion holding parts 81 to 84 are arranged in pairs in the left-right direction, and are arranged at the tips of the arms extending below the frame 85. As shown in FIG. 2, the transport jig 80 is capable of attaching one substrate support member 70 using first and second protrusion holders 81 and 82, and can attach one substrate support member 70 using third and fourth protrusion holders 83 and 84. One support member 70 can be attached. Recesses slightly larger than the outer diameters of the projections 71 and 72 of the substrate support member 70 are formed on the upper surfaces of the first to fourth projection holders 81 to 84. By placing the protrusions 71 and 72 in the recesses, the transport jig 80 can transport the substrate support member 70 while fixing its position in the front-rear direction. Although there are multiple types of substrate support members 70 depending on the type of substrate S to be supported, the outer diameters of the protrusions 71 and 72 are the same in all of them. In addition, the positions of the second protrusion holding part 82 and the fourth protrusion holding part 84 can be adjusted in the front-rear direction, thereby supporting multiple types of substrates with different sizes (distance between the protrusion 71 and the protrusion 72). Member 70 can be attached. The conveyance jig 80 has substantially the same width in the left-right direction as the mask fixing portion 27 of the screen mask M. Thereby, the transport jig 80 can be transported along the same transport rail 29 as the screen mask M. Further, since the same storage section 60 can be used for the transport jig 80 and the screen mask M, it is preferable that the lengths of the transport jig 80 and the screen mask M in the front-rear direction are similar. Note that the transport jig 80 may have a plurality of types having different sizes of the frame body 85 and the protruding holding portion, and a bar code 86 for recognizing the type of the transport jig 80 is provided on the top surface of the frame body 85. is installed.

Next, a description will be given of a process in which the printing apparatus 20 prints on the substrate S while automatically replacing the screen mask M and the substrate support member 70. FIG. 6 is a flowchart showing an example of a print processing routine executed by the CPU of the control unit 21. As shown in FIG. 7 to 9 are explanatory diagrams showing how the screen mask M and the substrate support member 70 are replaced. FIG. 10 is an explanatory diagram of the transportation, adsorption, and printing processing of the substrate S.

The print processing routine is stored in the HDD of the control unit 21 and executed after the operator instructs the printing device 20 to perform print processing. When the print processing routine is executed, the CPU of the control unit 21 first performs a process of replacing the screen mask M existing in the mask working unit 26 and the substrate supporting member 70 existing in the first and second substrate fixing units 30 and 40, that is, It is determined whether a setup change is necessary (step S100). For example, the control unit 21 determines whether setup change is necessary based on the information regarding the printing process acquired from the management PC 90, depending on whether the screen mask M and the substrate support member 70 required for the printing process are different between the previous time and this time. Determine whether In addition, when a setup change is required, as shown in FIG. It is assumed that a transport jig 80 for attaching the substrate support member 70 is stored in advance by the operator. Note that the operator reads the barcode 76 or the barcode 86 with a barcode reader as necessary to check whether the correct member is stored in the storage section 60. Furthermore, the operator adjusts in advance the positions of the second protrusion holding part 82 and the fourth protrusion holding part 84 in the front and back direction of the transport jig 80 for attaching the substrate support member 70 to be carried out.

If a setup change is required in step S100, the control unit 21 performs a mask unloading process to unload the screen mask M to be unloaded from the mask working unit 26 (step S110). The control unit 21 moves the transport rod 25a to transport the screen mask M to be carried out, which is present in the mask working unit 26, to the rear while sliding it on the transport rail 29, as shown in FIG. 7(a). . Furthermore, the conveyor elevating section 62 and the transport conveyor 61 are controlled to place the screen mask M to be carried out on the empty transport conveyor 61. Note that in order to perform the replacement process of the substrate support member 70, it is necessary to take out the screen mask M in the mask working section 26 once. Export process will be carried out.

Subsequently, the control unit 21 performs a support member unloading process to unload the substrate supporting member 70 to be unloaded from the first and second substrate fixing units 30 and 40 (step S120). The control unit 21 first controls the conveyor elevating unit 62 and the transport conveyor 61 to carry the empty transport jig 80 onto the transport rail 29, and further moves the transport rod 25a forward to move the first and second substrates. The transport jig 80 is transported to above the fixing parts 30 and 40 (FIG. 7(b)). At this time, the control unit 21 causes the first to fourth protrusion holders 81 to 84 to be positioned offset from directly above the protrusions 71 and 72 of the substrate support member 70 in the front-rear direction (eg, rearward). Subsequently, the control unit 21 releases the fixation of the substrate support member 70 on the support stands 37 and 47. Specifically, the control unit 21 moves the Y-axis pressing units 38, 48 forward, moves the Z-axis clamp units 39, 49 upward, and uses the substrate guide moving units 33, 43 to move the pair of side frames 30b. , 40b are spaced back and forth (FIG. 7(c)). Next, the control unit 21 raises the substrate support members 70 on the support stands 37 and 47 using the support stand lift units 35 and 45 and the fixing unit lift units 36 and 46, respectively (FIG. 8(a)). As a result, the protrusions 71 and 72 of the substrate support member 70 rise above the first to fourth protrusion holding parts 81 to 84. Subsequently, the control unit 21 moves the transport jig 80 forward using the transport rod 25a, and places the first and second protrusion holding parts 81 directly below the protrusions 71 and 72 of the substrate support member 70 on the support stand 37. , 82 are positioned, and the third and fourth protrusion holders 83 and 84 are positioned directly below the protrusions 71 and 72 of the substrate support member 70 on the support stand 47 (FIG. 8(b)). Then, the control unit 21 lowers the support stands 37, 47. As a result, the two substrate supporting members 70 are attached to the transport jig 80 with the protrusions 71 and 72 held on the first to fourth protrusion holding parts 81 to 84 (FIG. 8(c)) ). Thereafter, the control unit 21 lowers the entire first and second substrate fixing parts 30, 40 using the fixing part elevating parts 36, 46, and transfers the transport jig 80 to which the two substrate support members 70 to be carried out are attached. It is moved rearward by the transport rod 25a (FIG. 9). Then, the control unit 21 places the transport jig 80 to which the substrate support member 70 is attached on the empty transport conveyor 61 as it is. As described above, the control unit 21 performs the support member unloading process of the substrate support member 70 by combining the forward and backward transport of the transport jig 80 and the lifting and lowering of the support stands 37 and 47.

After the support member carry-out process in step S120, the control unit 21 performs a support member carry-in process to carry the substrate support member 70 to be carried into the first and second substrate fixing parts 30 and 40 (step S130). This process can be performed in the reverse order of the support member unloading process described above. That is, the control unit 21 first transports the transport jig 80 to the front to which two board support members 70 to be carried are attached (FIG. 9), and transports the board support members 70 to above the support stands 37 and 47. (FIG. 8(c)), and the support stands 37, 47 are raised to lift the protrusions 71, 72 from the first to fourth protrusion holding parts 81 to 84 (FIG. 8(b)). Subsequently, the control unit 21 moves the transport jig 80 backward (FIG. 8(a)), and then lowers the support stands 37, 47 (FIG. 7(c)). Next, the control unit 21 moves the transport jig 80 backward and carries it out, and positions and fixes the substrate support member 70 on the support stands 37, 47 (FIG. 7(b)). Specifically, first, the control unit 21 causes the pair of side frames 30b, 40b to approach each other in the front and rear directions using the board guide moving units 33, 43, and moves the support plates 39a, 49a to predetermined positions. The positions in the front-rear direction to which the support plates 39a and 49a are moved are determined in advance according to the type of the substrate S to be printed, the type of the substrate support member 70, and the like, and are obtained from the management PC 90, for example. Subsequently, the control section 21 moves the Y-axis pressing sections 38 and 48 backward, and moves the substrate support members 70 on the support stands 37 and 47 backward until they abut against the support plates 39a and 49a, respectively. In this way, by moving the support plates 39a, 49a and the Y-axis pressing parts 38, 48 back and forth, even if the position of the substrate support member 70 removed from the transport jig 80 is shifted back and forth, the substrate support The member 70 can be positioned in an appropriate position. When the substrate support member 70 is brought into contact with the support plates 39a, 49a, respectively, the control unit 21 moves the Z-axis clamp parts 39, 49 downward to press the clamped part 74, and presses the clamped part 74 on the support bases 37, 47. The position of the substrate support member 70 is fixed. As described above, the control unit 21 performs the support member loading process of the substrate support member 70 by combining the forward and backward transport of the transport jig 80 and the lifting and lowering of the support stands 37 and 47. Further, the control unit 21 positions the substrate support member 70 in the front-rear direction.

After the support member carry-out process in step S130, the control unit 21 performs a mask carry-in process to carry the screen mask M to be carried into the mask working unit 26 (step S140). The control unit 21 performs this process in a reverse procedure to the mask carry-out process. That is, the control section 21 first controls the conveyor elevating section 62 and the transport conveyor 61 to transport the screen mask M to be carried in to the top of the transport rail 29, moves the screen mask M forward by the transport rod 25a, and transfers it to the mask working section. 26. Note that if the screen mask M is not to be replaced, the screen mask M carried out in the mask carrying-out process is carried in.

When the process of replacing the screen mask M and the substrate support member 70 is completed by performing the processes of steps S110 to S140, the control unit 21 acquires the horizontal position information of the substrate support member 70 that has been carried in (step S150). A correction value for the stop position of the substrate S is determined based on the position information obtained (step S160). The control unit 21 moves the carriage 51 above the support stand 37 as shown in FIG. 10A, and causes the position information acquisition unit 55 to image the identification unit 75 on the upper surface of the substrate support member 70. Then, the control unit 21 detects the positional shift of the substrate support member 70 on the support stand 37 in the left-right direction (the conveyance direction of the substrate S) based on the position of the identification unit 75 in the image acquired from the position information acquisition unit 55. Then, a correction value for the stop position of the substrate S during transportation is derived and stored in a RAM or the like. Here, if the substrate support member 70 is shifted in the transport direction of the substrate S on the support stand 37, a problem may occur in suction and fixation of the substrate S depending on the stop position of the substrate S. If the position of the board support member 70 is shifted in the left-right direction, the control unit 21 also corrects the stop position of the board S by that amount so that the positional relationship between the board support member 70 and the board S does not change. It is to make it. The control unit 21 similarly acquires position information and derives correction values for the substrate support member 70 on the support stand 47.

After step S160 or if setup change is not required in step S100, the control unit 21 drives the substrate conveyor 31 to convey the substrate S to the first substrate fixing unit 30 (first lane), and S is adsorbed onto the substrate support member 70 (step S170). When conveying the substrate S to the first substrate fixing section 30, the control section 21 moves the carriage 51 back and forth and left and right, lowers the substrate stopper 56, and moves the substrate S conveyed rightward to the substrate support member. It is stopped at a predetermined stop position on 70 (FIG. 10(b)). At this time, if there is a correction value derived in step S160, the substrate stopper 56 is moved to a position that takes the correction value into consideration. Further, the control unit 21 raises the support stand 37, brings the upper surface of the substrate support member 70 into contact with the lower surface of the stopped substrate S, and fixes the substrate S by suction using the negative pressure from the pressure reducing device.

Subsequently, the control unit 21 performs imaging processing of the identification portions of the substrate S and screen mask M by the position information acquisition unit 55 (step S180), and identifies the pattern holes 11 of the substrate S and screen mask M based on the obtained images. The positions are adjusted so that they are at appropriate positions (step S190). Then, the control unit 21 starts printing on the first substrate fixing unit 30 (step S200, FIG. 10(c)). The control unit 21 raises the first substrate fixing unit 30 and brings it into contact with the upper surface of the substrate S and the lower surface of the screen mask M. Then, the print head 23 is moved onto the screen mask M on the first lane side, the solder paste is discharged under pressure from the print head 23, and the squeegee 25 is moved back and forth to print the solder paste onto the substrate S.

After the printing process in the first substrate fixing unit 30, the control unit 21 determines whether the production process is completed based on whether there is a substrate S to be printed next (step S210). If the production processing is not completed, the second substrate fixing section 40 is used to transport the substrate S, adjust the position of the screen mask M, print processing, etc. (steps S220 to S250). This process is similar to the process (steps S170 to S200) in the first substrate fixing section 30 described above, so a detailed explanation will be omitted. After step S250, the control unit 21 determines whether or not production has been completed (step S260), and if it has not been completed, executes the process of moving on to step S100. That is, the printing process is sequentially performed on the substrates S fixed to the first and second substrate fixing parts 30 and 40, while changing the setup as necessary. When the production process is completed in step S210 or S260, the control unit 21 ends this routine.

Here, the correspondence between the constituent elements of this embodiment and the constituent elements of the present invention will be clarified. The transport rod 25a of this embodiment corresponds to the support member transport section of the present invention, and the control section 21 corresponds to the exchange control section. Further, the first and second substrate fixing parts 30 and 40 correspond to substrate fixing parts, the Y-axis pressing parts 38 and 48, the substrate guide moving parts 33 and 43, and the support plates 39a and 49a correspond to positioning parts, The substrate transport conveyors 31 and 41 correspond to a substrate transport section, the position information acquisition section 55 corresponds to a position information acquisition section, the control section 21 and the substrate stopper 56 correspond to a correction section, and the support stands 37 and 47 correspond to a support stand. The support platform elevating parts 35, 45 and the fixed part elevating parts 36, 46 correspond to the support member elevating part, and the transport jig 80 corresponds to the transport jig.

The printing apparatus 20 of the embodiment described in detail above includes a support member transport section (transport rod 25a) that carries in and out the screen mask M and the substrate support member 70. In this printing device 20, the support member replacement process (steps S120 and S130) including carrying out and carrying in the substrate support member 70 can be executed using the transport rod 25a, and the automatic exchange of the substrate support member 70 can be performed. It can be carried out. Further, this printing device 20 can also perform a mask exchange process (steps S110 and S140) in which the screen mask M is carried in and out using the transport rod 25a. That is, automatic exchange of the substrate support member 70 and automatic exchange of the screen mask M can be performed together using the same transport rod 25a. Therefore, the apparatus configuration can be made more compact than, for example, when the printing apparatus 20 separately includes a transport section for replacing the screen mask and a transport section for replacing the substrate support member.

The printing apparatus 20 also includes first and second substrate fixing parts 30 and 40, which can fix the substrate S by the substrate support member 70 arranged when performing printing processing. 1. A positioning section that moves the substrate support member 70 disposed on the second substrate fixing section 30, 40 and positions the substrate support member in the horizontal direction (Y-axis pressing section 38, 48, substrate guide moving section 33, 43) , and support plates 39a, 49a). In the support member import process, the control unit 21 controls the transport rod 25a to transport the substrate support member 70 to be transported to the first and second substrate fixing parts 30, 40, and the Y-axis pressing parts 38, 48. , the substrate guide moving parts 33, 43, and the support plates 39a, 49a to position the transported substrate support member 70 in the front-rear direction. Therefore, it is possible to suppress the displacement of the substrate support member 70 carried in in the support member carrying process in the front-rear direction within the first and second substrate fixing parts 30 and 40.

Further, the printing device 20 includes first and second substrate fixing sections 30 and 40, substrate conveyors 31 and 41 that convey the substrate S in a predetermined substrate conveyance direction (left and right direction), and first and second substrate fixing sections 30 and 40, and a position information acquisition section 55 that acquires position information regarding the position of the substrate support member 70 disposed in the sections 30 and 40 in the substrate conveyance direction. Then, the printing device 20 includes a correction unit (control unit 21 and substrate stopper 56). As a result, even if the position of the substrate support member 70 carried into the first and second substrate fixing parts 30 and 40 in the support member carrying process is shifted in the substrate transport direction, the stop position of the substrate S is determined based on the position information. can be corrected. Therefore, problems in fixing the substrate S by the substrate support member 70 can be suppressed.

Furthermore, the printing device 20 has support stands 37 and 47 on which a substrate support member 70 can be placed, and first and second substrates on which the substrate S is fixed by the substrate support member 70 placed when performing printing processing. Fixing parts 30, 40, support platform elevating parts 35, 45, and fixed part elevating parts 36, 46, which raise and lower the substrate support members 70 disposed on the support stands 37, 47 by raising and lowering the support stands 37, 47, It is equipped with Then, the transport rod 25a carries in and out the transport jig 80 to which the substrate support member 70 can be attached, and the control unit 21 controls the transport rod 25a, the support platform elevating parts 35 and 45, and the fixed part elevating and lowering in the support member transporting process. By controlling the parts 36 and 46, the transport jig 80 is transported to above the first and second substrate fixing parts 30 and 40, and the board support member 70 to be carried out is placed on the support stands 37 and 38. is raised and attached to the transport jig 80, and the mounted transport jig 80 is carried out. In addition, in the support member loading process, the control unit 21 controls the transport rod 25a, the support platform elevating parts 35, 45, and the fixed part elevating parts 36, 46 to The tool 80 is conveyed to above the first and second substrate fixing parts 30, 40, the support stands 37, 47 are raised, and the substrate support member 70 to be carried is removed from the conveyance jig 80 and placed on the support stands 37, 47. The transport jig 80 is disposed in the same place, and the transport jig 80 is transported out after being removed. In this way, even if, for example, the shape or size of the substrate support member 70 is not suitable for transportation by the transportation rod 25a, the support member replacement process can be performed by transporting the substrate support member 70 using the transportation jig 80. can. In the printing apparatus 20 of this embodiment, the transport rod 25a transports the screen mask M and the substrate support member 70 together, but since the substrate support member 70 has a smaller width in the left and right direction than the screen mask M, the transport rod 25a transports the screen mask M and the substrate support member 70. It is not possible to directly transport the substrate support member 70 by the transport rod 25a by sliding the substrate supporting member 70. In this way, when the screen mask M and the substrate support member 70 have different shapes and sizes, the use of the transport jig 80 is highly significant.

The printing apparatus 20 also includes a first substrate fixing section 30 and a second substrate fixing section 40 as a substrate fixing section, and a first support member elevating section (a first support member elevating section for elevating the support table 37 as a supporting member elevating section). It has a support platform elevating section 35 and a fixed section elevating section 36), and a second support member elevating section (supporting platform elevating section 45 and fixed section elevating section 46) that raises and lowers the support platform 47. Further, the transport rod 25a carries in and out a transport jig 80 to which a plurality of substrate support members 70 can be attached. Then, in the support member unloading process, the control unit 21 controls the transport rod 25a, the support platform elevating parts 35, 45, and the fixed part elevating parts 36, 46 to carry in the transport jig 80, Each of the substrate support members 70 to be carried out disposed in is raised and attached to the transport jig 80, and the mounted transport jig 80 is carried out. In addition, in the support member carrying-in process, the control unit 21 controls the transport rod 25a, the support platform elevating parts 35, 45, and the fixing part elevating parts 36, 46 to arrange the objects to be carried in on the support platforms 37 and 47, respectively. The transport jig 80 with the board support members 70 attached thereto is carried in, the support stands 37 and 47 are raised, and each of the board support members 70 to be carried in is removed from the transport jig 80 and placed on the support stands 37 and 47. A process of carrying out the conveyance jig 80 after disposing and removing the conveyance jig 80 is performed. Thereby, the control unit 21 replaces the substrate support member 70 placed on the support stand 37 and the substrate support member 70 placed on the support stand 47 in parallel. By doing this, the substrate supporting members 70 to be carried out placed on the support stands 37 and 47 can be carried out together when the carrying jig 80 is carried in and out once, and the substrate supporting members 70 to be carried out can be carried out together when the carrying jig 80 is carried in and out once. Since the substrate support members 70 to be carried in, which are placed at 37 and 47, can be carried in together, the time required for the support member replacement process can be shortened.

It goes without saying that the present invention is not limited to the embodiments described above, and can be implemented in various forms as long as they fall within the technical scope of the present invention.

For example, in the embodiment described above, the control unit 21 uses the transport jig 80 to which two substrate support members 70 can be attached, and replaces the substrate support members 70 placed on the support stand 37 and places them on the support stand 47. Although the replacement of the substrate support member 70 was performed in parallel, the present invention is not limited to this. For example, only one of the substrate support members 70 on the support stands 37, 47 may be replaced. Further, in this case, the control unit 21 may perform the support member import process and the support member export process in parallel. FIG. 11 is an explanatory diagram showing how support member import processing and support member export processing are performed in parallel. Here, a case will be described in which the substrate support member 70 of the second substrate fixing section 40 is replaced. The control unit 21 first transports the transport jig 80 to which the substrate support member 70 to be transported is attached to above the second board fixing unit 40 (FIG. 11(a)). Next, the control unit 21 raises the substrate support member 70 to be carried out placed on the support stand 47 and attaches it to the transport jig 80 (FIG. 11(b)). The transport jig 80 is further transported forward to transport the substrate support member 70 to be carried in above the support stand 47, and the support stand 47 is raised to remove the board support member 70 to be carried in from the transport jig 80. The controller 21 then carries out the removed transport jig 80 (the transport jig 80 to which the substrate support member 70 to be carried out is attached) to the rear. In this way, it is possible to carry out and carry in the substrate support member 70 by carrying in and out the transport jig 80 once. Therefore, the time required for the support member replacement process can be shortened.

In the embodiment described above, the printing apparatus 20 was able to transport the screen mask M and the substrate support member 70 together using the transport rod 25a, but the present invention is not limited to this. If the support member transport section that carries in and out the substrate support member 70 is provided, at least the substrate support member replacement process can be performed. Also in this case, by moving the substrate supporting members 70 disposed on the first and second substrate fixing parts 30 and 40 and positioning the substrate supporting members in the horizontal direction, the first and second substrate supporting members 70 can be moved. The effect of suppressing displacement in the front-rear direction within the second board fixing parts 30 and 40 can be obtained. Note that although the above-described embodiment has been described as the printing apparatus 20 that replaces the substrate support member 70, the present invention is not limited to a printing apparatus as long as it performs the substrate support member replacement process. INDUSTRIAL APPLICATION This invention is applicable to the board|substrate work apparatus which performs board|substrate work on the board|substrate fixed on the board support member. An example of a board-related work device other than a printing device is a mounting device that performs a process of mounting components onto a board. Further, in the embodiment described above, the printing apparatus 20 was equipped with the transport rod 25a as a support member transport unit, but if it is possible to carry in and take out the substrate support member 70, it may be equipped with any kind of support member transport unit. It's okay. For example, the support member conveyance unit may be a support member conveyor including a conveyor belt and a belt rotation device that rotates the conveyor belt.

In the embodiment described above, the substrate support member 70 is conveyed using the conveyance jig 80. However, if the substrate support member 70 can be conveyed using the conveyance rail 29 and the conveyance rod 25a, for example, the conveyance jig 80 may be used. It doesn't have to be used.

In the embodiment described above, the Y-axis pressing section 38, the substrate guide moving section 33, and the support plate 39a are used to position the substrate support member 70 in the front-rear direction, but it is also possible to position the substrate support member 70 in the horizontal direction. However, it is not limited to this. For example, in addition to or instead of positioning in the front-back direction, positioning in the left-right direction may also be performed.

In the embodiment described above, the protrusions 71 and 72 of the substrate support member 70 have a cylindrical shape, but the shape is not limited to this as long as they can be attached to and removed from the transport jig 80. For example, the protrusion may have a rectangular prism shape, a plate shape, or a single member made of two adjacent cylinders. Furthermore, although the number of protrusions is two on each side, the present invention is not limited to this, and there may be one or more protrusions on each of the left and right sides.

In the embodiment described above, the first to fourth protrusion holding parts 81 to 84 hold the protrusions 71 and 72 using recessed parts, but the present invention is not limited to this as long as they can be attached to and removed from the transport jig 80. For example, assume that the transport jig 80 is provided with a pair of plate-like members protruding inside the frame 85, and by placing the protrusions 71 and 72 on the upper surface of the plate-like members, the transport jig 80 The substrate support member 70 may be attached. Furthermore, when removing the substrate support member 70 from the transport jig 80, the lifting of the substrate support member 70 and the transport of the transport jig 80 are combined, but the present invention is not limited to this. For example, the transport jig 80 includes a button that can be pressed downward, a lever that rotates on its axis as the button moves up and down and converts the vertical movement into horizontal movement, and moves in the horizontal direction as the lever rotates. A plate-like member moving mechanism may be provided. In this case, the substrate supporting member 70 is placed on the plate-like members of the pair of front and rear plate-like member moving mechanisms and transported, and the pair of plates is moved by pressing the button of the pair of plate-like member moving mechanisms using, for example, the transport rod 25a. The substrate supporting member 70 may be removed from the transport jig 80 by separating the shaped members from side to side. If such a mechanism is adopted, when removing the substrate support member 70 from the transport jig 80, there is no need to carry the transport jig 80 back and forth.

In the embodiment described above, the printing device 20 is provided with the storage section 60, but the printing device 20 does not need to be provided with the storage section 60. Further, although the printing device 20 is a dual lane printing device having the first and second substrate fixing parts 30 and 40, the present invention is not limited to this. For example, the printing device 20 may be a single-lane printing device having one substrate fixing section.

In the embodiment described above, the substrate support member 70 is a member that supports the substrate S from the lower surface side using negative pressure and fixes it by suction, but it may be any member that fixes the substrate. For example, the substrate support member may include a plurality of protrusions (backup pins) erected on the upper surface, and the substrate support member may support and fix the substrate S from below using the protrusions. .
