Punch card viewer
Abstract
Abstract A Punch Card Viewer is provided in the form of a magnifying glass having a flat rear face and a rounded magnifying top face and a vertically extending leading slot adapted to block out all data and holes when the viewer is maintained flush with the bottom edge of the punch card. The viewer can be guided upon the lower edge of the punch card by the thumb while grasping the viewer and extending it over the card or by a ledge extending rearwardly from the rear face of the viewer. The viewer has a pocket clip so as to keep the viewer in the pocket of the card reader. Horizontal line designations are provided upon the viewer adjacent to the vertically extending reading slot. There is also provided a card viewer which may extend over the full face of the punch card and which has rearwardly extending ledges at the upper and lower edges of the viewer to keep the card confined against vertical displacement and also has lines to box in the horizontal rows of holes and data upon the card. This full viewer has a vertically extending reading slot on an extension thereof at one end which can be aligned with any vertical row of holes or data upon the card. The viewer can also be provided with space for the displaying of essential data, which aids the reader of the card in making his deductions therefrom.
