Abstract
A drum speed synchronization signal is transmitted for a predetermined length of time followed by a picture signal. Timing means are arranged to be triggered upon initiation of the synchronization signal to enable a drum speed synchronizer to receive the synchronization signal for a period of time which ends shortly before termination of the synchronization signal to positively prevent the picture signal from being erroneously received by the synchronizer. The timing means enables a printing element to receive the picture signals shortly after termination of the synchronization signal to positively prevent the synchronization signal from being erroneously reproduced.
Claims6
A facsimile receiving apparatus responsive to a synchronization signal and a picture signal for reproducing a picture corresponding to the picture signal, the synchronization signal being produced for a first predetermined length of the time followed by the picture signal, the apparatus comprising:
- printing means including printing element means responsive to the picture signal and scan drive means;
- synchronization means responsive to the synchronization signal for synchronizing the scan drive means in accordance therewith;
- synchronization timing means responsive to initiation of the synchronization signal and connected to enable the synchronization means to receive the synchronization signal only for a second predetermined length of time between said initiation of the synchronization signal and termination thereof, the second predetermined length of time being shorter than the first predetermined length of time;
- and
- print timing means responsive to said initiation of the synchronization signal and connected to enable the printing element means to receive the picture signal only after a third predetermined length of time after said initiation of the synchronization signal.
