<p>PURPOSE:To facilitate cargo handling operaion by coupling trays by a V-shaped ring, and by widening the distance between the trays using a link only when sheet-shaped cargo is to be handled. CONSTITUTION:Angle-shaped links 121, 122, each of which has one end pivoted rotatable with respect to each tray 31-310 and the other end coupled with the one of other members rotatably, are interposed between two adjoining trays of a group of trays 3, so as to widen the angle-shaped link 12 located between two adjoining trays mating with the sheet exhaust hole of an amage forming device by a means 16 to protrude and retract installed in the position mating with the sheet exhaust hole of the image forming device. Thus the distance between the trays is widened. Accordingly this simple construction allows widening of the space between other trays only tray 35 onto which the sheet is to be fed, to ensure easy accommodation of sheets without involving increase of the whole thickness of the group of trays.</p> |
