Each of the lifting and extracting devices 42 can sequentially pass the first moving stage 40, the camera module 43 and the second moving stage 44 along with the rotation of the turntable 41, and one of the lifting suctions 42 When the pre-takeout position above the first moving stage 40 is reached, the turntable 41 is paused, and the other two lift absorbers 42 are just stopped directly above the camera module 43 and the second. A preliminary placement position above the moving stage 44 is as shown in FIG.

After the UV film carrier 1 is transported from the first inspection device 3 to the first moving stage 40 of the second inspection device 4 by a second transport device (not shown) or manually, Each lifter 42 reaches the preliminary take-up each time When the position is taken out, the UV film carrier 1 on the first moving stage 40 is lowered, and the top surface 201 of a piece of the filter 2 on the UV film carrier 1 is sucked, and then sucked together The filter 2 is raised and returned to the preliminary take-out position, and thus, the operation of sucking a piece of the filter 2 from the UV film carrier 1 is completed. The second inspection device 4 preferably further includes a ejector mechanism (not shown) on the first moving stage 40, and the ejector mechanism performs the suction of the filter at each lifting and lowering device 42. During the operation of the sheet 2, the filter 2 currently to be taken out is topped up to facilitate the lifting and lowering of the filter 2 by the lifting and lowering device 42 and the removal of the filter 2 from the UV film carrier 1 The UV film 11 is. Thus, in conjunction with the two-dimensional movement of the first moving stage 40, the lifting and extracting devices 42 can remove the filter 2 on the UV film carrier 1 one by one for the subsequent camera module. 43 to shoot.
