PROBLEM TO BE SOLVED: To provide a radio device capable of continuously efficiently transmitting/receiving data or packets by simple processing.SOLUTION: A transmission buffer includes a plurality of transmission buffer surfaces of specific capacity; a transmission control circuit 24 stores the number of transmission buffer usage representing the number of transmission buffer surfaces with data stored therein; when transmission data are input from the outside, the transmission data of a unit quantity preset not more than the specific capacity are sequentially written from the head of each transmission buffer surface based on a writing transmission buffer pointer, and the number of transmission buffer usage is incremented; when the number of transmission buffer usage reaches an upper-limit value, transmission data of a unit quantity are sequentially read from the head of the transmission buffer surface based on the reading transmission buffer point and transmitted to a radio control part 10, and the number of transmission buffer usage is decremented; and when once the number of transmission buffer usage reaches the upper-limit value, and is thereafter set below the upper-limit value, the next transmission data are written in the transmission buffer surface becoming unused. |
