    • A large number of cards are vertically randomly stored on a horizontal platen. Each card has a serrated bottom code edge contacting the platen, a magnetic chip implanted in a vertical edge and a hook on the upper edge. Selected serrations are removed from the bottom edges of the cards to constitute a selection code. Selected sorting bars are raised into position between the serrations, and a magnet attracts the magnetic chips so that only the selected card having serrations removed corresponding to the raised sorting bars is pulled horizontally backward by the magnet by a distance of one serration. A push bar then engages with the hook of the selected card, and pushes the selected card horizontally forward and simultaneously lifts the selected card clear of the other cards to a retrieval position.
    • 大量的卡被垂直地随机存储在水平台板上。 每个卡具有与压板接触的锯齿形底部码边缘,注入垂直边缘的磁性芯片和上边缘上的钩状物。 选择的锯齿从卡的底部边缘移除以构成选择代码。 所选择的分选条被提升到锯齿之间的位置,并且磁体吸引磁性芯片,使得只有具有相应于凸起的分选条移除的锯齿的所选择的卡水平地被磁体向后拉动一个锯齿的距离。 然后,推杆与所选择的卡的钩接合,并且将所选择的卡水平向前推动并同时将选定的卡从其他卡提升到检索位置。

    • An improved accessory device for increasing the effective card storage capacity of retrieval systems in which edge-notched coded cards are randomly stored in face-to-face upstanding relation on a platen in a card selector apparatus. The accessory device includes a two-piece card tray having a substantially planar bottom panel against which the code-notched edges of the cards rest when stored face-to-face in a vertical disposition, and a retaining structure at least partially surrounding the upstanding cards. The retaining structure is positionable between engaged and disengaged positions relative to the bottom panel, thereby facilitating transfer of the cards between the tray and the selector. The retaining structure, when engaged with the bottom panel, cooperates therewith to store the cards in the tray. Alternatively, and when the retaining structure is in the course of being positioned between its engaged and disengaged positions relative to the panel, the retaining structure functions to transfer the cards between a position of support on the bottom panel and a position of support in the card selector. Also included are structural features for improving the positioning of cards and locking the retaining structure both relative to the selector, when the cards are in the selector and positioned by the retaining structure.
