Abstract: This cabinet has a plurality of vertically spaced, horizontally disposed, stationary shelves, which are closed at their rear ends and open at their forward ends. Slidably mounted between an adjacent pair of the stationary shelves is a movable, pull-out shelf, opposite sides of which are mounted on conventional roller brackets for movement between a retracted position in which the shelf is fully seated within the cabinet, and an extended position in which it projects horizontally from the front of the cabinet. The movable shelf is designed to simplify a cancelled check in-filing operation, and for that reason has a horizontally disposed, central recess for removably supporting thereon a check filing tray, and a pair of horizontally disposed, arm-supporting surfaces which are positioned adjacent opposite sides of the central recess.
