<p>PURPOSE:To prevent a memory card from being damaged or being made dirty and to prevent memory information from being erroneously read by fitting plural memory cards so as to be freely attached/detached and providing a card magazine to index the prescribed memory card at a prescribed position. CONSTITUTION:When a pallet fitted with work is conveyed into an NC machine tool 1, a pallet No. is read and transmitted to a controller 24 of a memory card stocker 2. The controller 24 retrieves an IC card 20, corresponding to the pallet No. from a card magazine 21 and indexes the memory card at the read/write position of a reader/writer 23. The work information of the IC card 20 read by the reader/writer 23 is transmitted through the controller 24 to an NC device 10 at the NC machine tool 1. Thus, the memory card 20 is prevented from being damaged r being made dirty and the malfunction of the NC machine tool caused by transmitting erroneous information is eliminated.</p> |
