Scanner system with local scanning capability for graphic reading

摘要: A scanner system with local scanning capability for graphic reading, which comprises a tablet, scanner, stylus or cursor control mouse and main frame CPU. The plurality of oscillators (induction coils) at both sides by the light source thereof to produce induced current on plane circuit tablet. CPU tablet obtains X,Y coordinate data through sample-and-hold amplifier A/D converter circuit. Simultaneously, projects reflect picture CCD so as record start end location every line. After is read digital line image X, Y are stored in storage further processing its that any distortion can be modified achieved. controlled move provides high resolution 1000 lines per inch, such pitch between shortened, clear obtained.
