Abstract

PURPOSE:To ensure an automatic control for the jitter during the record and thus perform an assured reception of data, by delaying the synchronous signal by the time during which the received picture signals fill the full memory capacity of the temporary memory means. CONSTITUTION:The received picture signals are stored in the temporary memory 5 having a capacity to store the picture signals equivalent to a rotation of the drum. The reception control circuit 3 detects the print start, print stop and drum rotation signals out of the received signals. The synchronous circuit 4 applies the synchronous signal received from the demodulator circuit 1 to the delay circuit 11 after the input of the start signal. The circuit 11 and the delay circuit 10 that imputs the end signal have the delay characteristics corresponding to the drum rotational phases of 180 deg. and 360 deg. each. On the other hand, the synchronous signal supplied from the drum of the reception side is applied to the phase difference detection circuit 13 to receive a detection of the phase to the received synchronous signal received from the circuit 11. With this output of detection, the drum control circuit is controlled to ensure an automatic control of the jitter occurring in the recording.
