<p>PURPOSE:To attain the transmission from a slave station and to prevent an order error by storing registration data sent from a master station to plural slave stations and sending the data selected by the slave station only when the data are coincident with the registration data. CONSTITUTION:A call from a master station 1 is received by a slave station 2, and when an individual number included in the call is coincident with the identification number stored in a memory 28 of the slave station 2, a product name included in the call is stored in the memory 28 and the registration is replied to the master station 1. When the slave station 2 operates an entry key 26 and the selected product is in existence, whether or not product name data are coincident with data stored in the memory 28 is collated. When coincident, the product name stored in the memory 28 together with the individual number of the slave station 2 is sent to the master station 1 and the result of collation is displayed on a display device 25. Thus, product data are registered in the slave station and the transmission from the slave station is attained and the occurrence of an order trouble is prevented.</p> |
