PURPOSE:To make it possible to individually send production instructions to auxiliary instruction card lines, by providing such an arrangement that dummy cards inserted among instruction cards in the auxiliary instruction card lines are discharged upon merging of the lines. CONSTITUTION:A central production instructing device 10 is provided with first and second auxiliary instruction card lines 20, 21 for conveying instruction cards 11 and dummy cards 12. Accordingly, cards 11 to be fed to the second line are taken out from the instruction cards 11 which are lined up in the order of a production process, and dummy cards 12 are inserted instead therefor. Further, these cards are disposed in a card stocker 26 on the first line 20, and the cards taken out beforehand are disposed in a card stocker 28 on the second line 21. Further, the dummy cards are removed upon merging of both lines. Thus, it is possible to individually give production instructions to the auxiliary instruction card lines. |
