ABSTRACT:
An apparatus for successively removing stacked sheets, such as stimulable phosphor sheets used in electron microscopy, from a housing. The stack consists of alternate layers of a first kind and a second kind of sheets. Each sheet of the first kind has a first notch in a first position. Each sheet of the second kind has a second notch in a second position. One edge of the lowermost sheet of the stack is supported on a projection which can be moved along the edge. Thus, the stack is inclined in the housing. The projection is movable from its home position, first and second stop positions aligned with the notches. When the projection is moved to a position registering with the notch on the lowermost sheet, that sheet only is dropped to a position from which it is ejected from the apparatus.
