PURPOSE:To avoid inconvenience as a customer using credit card is waited for a long time, for example, by transmitting the card data stored in the priority buffer than the normal data in the normal buffers with priority. CONSTITUTION:Normal data is stored to the normal buffers 4'-0 to 4'-2, the normal buffer transmission pointer k indicates the buffer 4'-1, and the circuit control section 5 transmits the data in the buffer 4'-1. When the priority data is inputted, the data a editing this priority data is stored in the priority buffer 4-0 or 4-1 designated with the storage pointer information h. Further, the data in the buffer 4'-1 is transmitted and the transmission end signal 0 is turned on, then the control section 3 turns on the transmission section signal l to produce the transmission request. The data is picked up from the buffer 4-0 or 4-1 indicated with the transmission pointer information j, and this priority data is delivered to the center with the control section 5. |
