The first user goes through an input step of inputting to the microcomputer the width of the printed circuit board on which the work is to be performed. In this input step (S1) it is possible to sequentially input the size of a plurality of printed circuit boards. It inputs the width and size of various printed circuit boards in advance before starting work, and inputs all the information about the movement and distance of input equipment in the PC window environment, and the printed circuit boards that are working sequentially.

Next, after passing through the input step (S1) transfer conveyor descending step (S2) for lowering the conveying conveyor (100,300) with the power provided through the drive cylinders 110,310 of the conveying conveyor (100,300). Will go through. This descending step (S2) is the first driving step to automatically adjust the width of each of the conveying conveyors (100, 300) at the same time according to the information of the input printed circuit board.

And the conveying conveyor (100, 300) is lowered through the conveying conveyor descending step (S2) is passed through the connecting step (S3) connected to the workbench holder 210 installed by crimping on the workbench 200. This connection step (S3) is a step in which the ends of the first conveying conveyor 100 and the second conveying conveyor 300 are connected to each other while pressing the pressing lever 420 installed on both ends of the worktable holder 210.

Next, after the connecting step (S3), the worktable holder 210 is released from the crimping lever 420 which is crimping the workbench holder 210 to the workbench 200 so that the crimping state of the worktable 200 is released. In step S4. This pressing release step (S4) of each of the conveying conveyor (100, 300) is connected to the workbench holder 210, the pressing lever 420 of the crimping lever 420 of the workbench holder 210 is pressed The crimping part rotates partly to release the crimping state.
