Abstract
In a rotary file comprising a case open at the top, a card-holding rotor rotatably mounted in the case and a cover rotatable about the axis of the rotor from a closed position to an open position, a lock mounted in a side wall of the case near the back has a locking member which, in locked position, engages a rear portion of the cover when in closed position so as to keep the cover from rotating to open position. When the lock is turned to unlocked position, the locking member is moved clear of the cover so as to allow the cover to open.
