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.

Claims

1. A computer punch card viewer having a flat rear face adapted to overlie a punched computer card between its upper and lower edges and a rounded top surface to provide magnification for the reading of data upon the punched card, said computer card being of the standard type with twelve horizontal rows of punch hole locationS and these hole locations being arranged in a plurality of horizontally spaced vertical columns, a vertically extending reading slot extending from the lower end of the viewer to the upper end thereof and measured to extend between the upper and bottom horizontal rows and aligned to view punched holes of a vertical column of hole locations upon the card, the punched holes of the card and the hole locations being magnified upon a reading of the card being made through the vertically extending reading slot, a column of vertically extending designations for the several horizontal rows of the punched hole locations upon the card lying adjacent to the reading slot and spaced from one another equally and corresponding to the horizontal rows of data and holes upon the card, and a horizontally extending guide ledge at one end of the viewer on which the horizontal edge of the computer card may be rested and guided.

2. A punch card viewer, as defined in claim 1, and a pocket clip formation extending rearwardly and downwardly from the upper end of the viewer and serving to maintain the upper edge of the card against the rear face of the viewer while the card is being guided along the rearwardly extending ledge at the bottom of the viewer.

3. A punch card viewer, as defined in claim 1, and said curved surface extending vertically upon the viewer and flat side wings extending laterally therefrom.

4. A punch card viewer, as defined in claim 1, and said vertically extending reading slot being in the form of a series of vertically extending holes in the strip upon the rear face of the viewer.

5. A punch card viewer, as defined in claim 4, and said slotted strip providing on its rear face essential data information readable upon reversal of the viewer to present the rear face thereof.
