Desktop receptacle (2-4)
I believe the answer is:
in-tray
'desktop receptacle' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for in-tray that I've seen before include "Shallow container for letters etc" , "Office desk receptacle for new post" , "Place for matters to be dealt with" , "Desk item" , "Desktop receptacle" .)
