Abstract

Cells in an image storage and retrieval file are accessed into and out of the file pneumatically. A rectangular array of cells is loosely stored in a frame and several frames are suspended vertically, one behind another. No cells are stored in the bottom row of each frame. Thus, when all frames are in home position, an access tunnel extends through the file across its entire width.

This text was extracted from a PDF file.
At least one non-text object (such as an image or picture) has been suppressed.
This is the abbreviated version, containing approximately 100% of the total text.

Information Retrieval File

Cells in an image storage and retrieval file are accessed into and out of the file pneumatically. A rectangular array of cells is loosely stored in a frame and several frames are suspended vertically, one behind another. No cells are stored in the bottom row of each frame. Thus, when all frames are in home position, an access tunnel extends through the file across its entire width.

For accessing a cell, a frame is moved vertically until the desired cell is driven through the tunnel and out of the file pneumatically. An ejected cell is guided from the file to a fixed read station by a guide tube. A separate column tube interconnects each column across the access tunnel to the guide tube. These column tubes are stepped. They are moved vertically as a unit to position the appropriate column tube in alignment with the column from which a cell is to be stored or retrieved. Stepping of the column tubes causes the selected column tube to be in alignment with the fixed guide tube.
