テレビカメラ。A mechanical shutter blade is installed on the front of the image pickup tube to open and close the incident light of the information pattern on the image pickup tube. A synchronous drive device is provided for driving and operating the shutter blades in synchronization with a vertical synchronization signal so as to suppress incident light, and the accumulated charge remaining on the target surface after one frame scanning is discharged and attenuated by scanning. A television camera for reading information patterns, characterized in that it is designed to eliminate the occurrence of afterimages in the next captured frame.
