Abstract:
A card filing device for storing and viewing card carrying envelopes wherein slotted card carrying envelopes are pivotally mounted in the device so that they are movable from a horizontal storage position to a vertical viewing position and only removable from said container by pivoting the same to a position approximately midway between said storage and viewing positions.

Description:
BACKGROUND 
     The present invention generally relates to an information and retrieval system. In particular, it relates to a storage and viewing device for cards or the like. 
     In today&#39;s business world data processing and record keeping has become a very significant problem, due to the large volume of information that must be maintained. A partial answer to this problem has been the introduction of the technology of magnetically recording data. 
     A specific adaptation of this technology is the use of magnetic cards or &#34;Mag Cards&#34; in connection with a typewriter. 
     &#34;Mag Cards&#34; are thin, small flexible plastic cards which are easy to handle and file. As a typed card has approximately 50 recording tracks capable of storing about 5000 characters, it is far less space comsuming to store and less time consuming to use. However, like all data, it too must be stored yet be made readily available for use. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is an object of the present invention to provide a storage and retrieval system for &#34;Mag Cards&#34; and the like. 
     It is another object of the present invention to provide a compact storage and viewing unit for &#34;Mag Cards&#34; and the like. 
     It is a further object of the present invention to provide a storage and viewing device for &#34;Mag Cards&#34; and the like wherein said cards are contained in protective envelopes. 
     It is a still further object of the present invention to provide a storage and viewing unit for &#34;Mag Cards&#34; and the like wherein said cards are contained in identifying envelopes and said envelopes are releasably held in said unit. 
     The above and other objects and advantages of the present invention will be apparent from the following description, the accompanying drawings and the appended claims.

     DESCRIPTION OF PREFERRED EMBODIMENT 
     With reference to FIGS. 1, 2 and 4, it will be seen that the card filing device is designated as 10 and that it comprises two main parts, a container 12 and a plurality of card filing envelopes 14. 
     The container 12 is basically an open top, rectangular shaped box having front and rear walls 16 and 18, end walls 20 and 22 and a bottom 24. As shown, the front wall 16 is provided with a rectangular shaped opening or cut-out 26 disposed slightly inward of end wall 22. The opening 26 is open at the top and extends downwardly into said wall 16 to the bottom 24 or to a point slightly above the bottom 24, as depicted. Optionally, the back wall 18 is provided with a corresponding opening 28 located opposite said opening 26. 
     A pin or rod 30 is disposed between walls 16 and 18 so that its longitudinal axis is located above and approximately parallel to the bottom 24. As shown, the pin 30 acts as a pivot means for envelopes 14 and also retaining means for said envelopes as will be described further below. 
     As stated above, a plurality of card envelopes 14 are employed with the device for holding cards 15. Referring to FIG. 3, it will be noted that each envelope 14 is basically rectangular in shape with its long dimension along the sides thereof. As shown, the envelope 14 is of the sleeve type and is open at its top and at least partially along the right side thereof. Said envelope is provided with a false bottom or extension 32 and an index tab 34 adjacent the open side. Additionally, the front surface 35, and optionally the rear, of said envelope is provided with record identifying indicia 36 relating to the cards 15 carried by said envelopes. 
     A slot or notch 38, adapted to receive pin 30 of said container 12 is disposed approximately at a 45° to the horizontal in the corner of said false bottom 32 diagonally opposite said open side of said envelope 14. 
     With reference primarily to FIGS. 1 and 4, it will be noted that the card carrying envelopes 14 may assume two basic positions when used with the container 12. In the first or storage position, said envelopes are positioned on its closed side in said container so that the slot 38 is engaged with pin 30. In this position, the index tab 34 extends upwardly through the open top of said container, and the end of false bottom 32 extends to a point just short of said cut-out sections 26 and 28. The second or viewing position of said envelope is attained by rotating or pivoting said envelopes 14 clockwise about pin 30 from said storage position to an upright position, as depicted in FIGS. 1 and 4. In this viewing position, the identifying indicia 36 on the front 35 of said envelope 14 may be viewed through the opening 26, and the card 15 by said envelope easily removed therefrom for any desired purpose. 
     A unique feature provided by the device of the present invention is the manner in which envelopes 14 are removed or added to the container 12. As seen in the drawings, the envelopes are not removable from the container 12 while they are either in the storage or viewing position. This is due to the position of the slot 38 when engaged with pin 30 relative to the amount of clearance between the top of the envelope 14 and wall 20 when in the storage position or the right side of envelope 14 and wall 22 when in the viewing position. In order to remove or add envelopes 14, it is necessary to position the envelope approximately midway between the storage and viewing positions so that the slot 38 is disposed in an approximately vertical position.
