Abstract

A copy machine cabinet and lid construction in which the lid is carried by the cabinet for a swinging movement from a position over the cabinet top to a position away from the cabinet top. This lid is provided with a platen adapted to receive an original and with a platen cover which is mounted for a swinging movement between a position over the platen and a position away from the platen. As the lid is moved to a position to permit access to the parts within the cabinet, gravity responsive locks inhibit movement of the platen cover away from the platen.

Claims

1. Copying apparatus including in combination, a cabinet adapted to house the operating components of said apparatus, said cabinet having an open top, a lid, means mounting said lid on said cabinet for pivotal movement around a first horizontal axis between a closed position over the open top of said cabinet and an open position at which the interior of said cabinet is accessible, a platen in said lid for supporting a document to be copied, a platen cover, means mounting said cover on said lid for pivotal movement around a second horizontal axis parallel to said first axis between a first position at which said platen is covered and a second position at which said platen is exposed, interengageable elements on said lid and on said cover, said elements being movable between a first relative position out of engagement at which they permit relative movement of said lid and cover and a second relative position in engagement at which they inhibit relative movement of said lid and cover, said elements occupying said first relative position with said lid adjacent to said top, and gravity responsive means for moving said elements to said second relative position as said lid moves away from said top.
