Viewing device for microprint
Abstract
Abstract THE INVENTION PROVIDES A COMPACT DEVICE FOR STORING MANY THOUSANDS OF GRAPHIC CHARACTERS, E.G., CREDIT CARD NUMBERS ON A PAPER SCROLL MICROPRINTED ON BOTH X AND Y AXES BUT WHEREIN THE COMPRESSION IS GREATER ON THE X AXIS SO THAT A LARGE NUMBER OF COLUMNS OF NUMBERS CAN BE PRINTED ON THE SCROLL. BY A COMBINATION OF CYLINDRICAL AND SPHERICAL LENSES THE MICRO-PRINTED CHARACTERS ARE MADE READILY READABLE. THE SCROLL IS CARRIED ON A MANUALLY ROTATED GEARED ROLLERS WHICH ARE PARTICULARLY CONSTRUCTED TO GRIP A RESPECTIVE EDGE OF A PRINTED SCROLL WRAPPED AROUND THE ROLLERS AND FEEDING REVERSIBLY FROM ONE TO THE OTHER BELOW THE LENS SYSTEMS. THE STRUCTURE FURTHER CONTEMPLATES BEARING SUPPORT MEANS COMPRISED OF OPEN ENDED NOTCHES IN WALLS OF THE HOUSING TO ROTATIVELY SUPPORT THE ROLLERS AND GEARING AND A MANUALLY ROTATIVE KNOB, ALL MAINTAINED IN RESPECTIVE NOTCHES BY GRAVITY BUT READILY REMOVABLE FOR CHANGING THE PAPER SCROLL.
