Abstract
PURPOSE: To realize a high-speed and high-accuracy reading of the information for the information reading method using the pickup tube by erasing previously the region designated by the designation encoding signal under the access of the information to be supplied to the pickup device and the area of the position mark which detects the above mentioned designated region.
CONSTITUTION: In the system which uses pickup tube 5 to read out the characters and symbols, the character designation code is supplied to control circuit 1 and then to tube 5 via servo-control circuit 2 and the information on disk 4 attached to motor 3 to carry out the access for the information. And while motor 3 turns to perform the access, the area of the information designated by control circuit 6 plus the area where position mark M detecting the information region are erased previously by means of deflecting circuit 7. Then the discontinuation is detected by circuit 2 for the turn of motor 3, and the position detection is carried out via circuit 7 for the characters designated by circuit 6. Thus, the detected positions are projected on CRT9 via video amplifier 8.
