When there is an unoperated hole puncher, the control device 6 takes out the unprocessed printed circuit board waiting in the carry-in device 4, moves it on the transport line 1 and sets it in the unoperated hole puncher (step S). ₃ ).

When the unprocessed printed circuit board is set in the non-operational drilling machine, for example, the drilling machine 22, the identifier reading device 220 reads the content of the identifier of the set printed circuit board, and reads it. To the NC device. As a result, the drilling machine 22 performs drilling according to the program of the NC device.

When it is judged in step S ₁ or step S ₂ that there is no unprocessed printed circuit board or there is no idle puncher, or when the process of step S ₃ is completed, the control device 6 controls each It is determined whether or not there is a printed circuit board on which the punching process has been completed in the punching machines 21, 22, and 23 (step S ₄ ).
This judgment is made by the control device 6 by reading the work contents of the NC devices of the respective punching machines 21, 22, 23. When there is a printed circuit board for which drilling has been completed, it is next determined whether or not any of the contour processing machines 31, 32 is in operation, that is, whether there is a contour processing machine capable of performing contour processing. (Procedure S ₅ ). When there is a non-operating contour processing machine, the control device 6 takes out the printed circuit board in the punching machine, for which the punching has been completed, from the punching machine (step S ₆ ), and moves it on the transfer line 1 so that the punching machine is not in operation. Set it on the contour processing machine (step S ₇ ).

When the printed circuit board on which the punching process has been completed is set on the non-operating contour processing machine, for example, the contour processing machine 32,
The identifier reading device 320 reads the contents of the identifier of the printed circuit board that has been set, and transmits this to the NC device of the contour processing machine 32. As a result, the contour processing machine 32 causes the NC
Outer shape processing is executed according to the program of the device.

In steps S ₄ and S ₅ , when it is determined that there is no processing-completed printed circuit board or there is no idle contour processing machine, or when the processing in step S ₇ ends, the control device 6 It is determined whether or not there is a printed circuit board whose outer shape processing has been completed in each outer shape processing machine 31, 32 (step S).
₈ ). This judgment is made by the control device 6 by each of the contour processing machines 31, 32.
This is done by reading the work contents of the NC device. When there is a printed circuit board for which the outer shape processing has been completed, the control device 6 takes out the printed circuit board from the outer shape processing machine, and transfers it to the transfer line 1
Is moved to the discharge unit 5 through the (Step S _9), actuates the discharge device 5 sends out to the outside the printed circuit board as a processing completion substrate. When it is determined in step S ₈ that there is no printed circuit board for which outer shape processing has been completed, or when the process of step S ₉ is completed, the control device 6 returns the process to step S ₁ .
