Abstract

PURPOSE:To improve data transmission efficiency, by transmitting a key code corresponding to the key and key depressed frequency information as one data unit, when the same key is continuously operated for numerous times. CONSTITUTION:Central processor equipment 10 has a microprocessor 11, an ROM12, an RAM13, a display device 15, a printer 16, a keyboard 17, and a card reader 18, and terminal equipment 20 is connected to the central processor equipment 10 through a transmission controlling circuit 14. The terminal equipment 20 contains the same components as the central processor equipment 10 has, and the RAM30 has a key buffer 31, a register area 32, and a counter area 33. The key buffer 31 stores key codes inputted from a keyboard 22, and the register area 32 is used for shunting key codes read out from the key buffer 31. The counter area 33 stores depressed frequencies of keys after counting, and transmits key codes and key depressed frequencies to the central processor equipment 10 as data units. In this way, the central processor equipment can perform processings in accordance with the key depressed frequency information, and thus, the transmission efficiency can be improved.
