Abstract
Abstract A recording apparatus is provided with detecting means for detecting any abnormality of a synchronizing signal included in an incoming signal; processing means for processing the incoming signal into a print recording signal; and print recording means for carrying out print recording in accordance with the print recording signal. Erroneous recording is prevented by inhibiting the print recording signal from being supplied to the print recording means when any abnormality is detected in the synchronizing signal.
