Abstract
There have been a problem that if the capacity of a receiving buffer is small, data cannot be reliably received and another problem that the rate of detection of transmission errors caused by influence of noise is low. The IC card connector comprises a receiving buffer status flag ( ) set up when a receiving buffer ( ) cannot hold any more data, an overrun inspecting section ( ) for detecting reception of another data while the receiving buffer status flag ( ) is set up, and a resending request signal generating section ( ) for requesting an IC card to resend the received data if the overrun inspecting section ( ) detects overrun. If a receiving buffer ( ) receives another data though the receiving buffer ( ) cannot hold any more data, the IC card is requested to resend the data, and the same data is received again.
