Claim:
A display frame unit for assembling and mounting a jigsaw puzzle, comprising: a frame housing having spaced top and bottom frame margin pieces and spaced left and right end margin pieces extending between opposite ends of said top and bottom margin pieces; a light transmissive assembly plate, said margin pieces defining a continuous frame encircling said assembly plate, said assembly plate being recessed inwardly of an outer encircling face surface of said margin pieces so as to provide a space for receiving jigsaw puzzle pieces during user assembly of said puzzle pieces, edges of perimeter located puzzle pieces of an assembled puzzle closely abuttingly engaging with inner side faces of said continuous frame; a slide actuator member carried at a location on said encircling frame such that an end edge of a puzzle piece of an assembled puzzle present on said assembly plate which is juxtaposed with said slide actuator will urge said slide actuator counter to a bias acting thereon from an non operating position to an operating position; at least one light emitting member carried in said frame housing disposed behind said assembly plate; a source of electric power for operating said at least one light emitting member; a on-off switch in circuit with said source of electric power and said light emitting member for controlling power supply to said light emitting member; a normally open cut-out switch for interrupting a power flow from said battery to said light emitting member, said slide actuator being connected with said cut-out switch such as to move said cut-out switch to closed condition responsive to movement of said slide actuator from non-operating to operating position whereby with said off-on switch in on position, power will flow to said light emitting member illuminating said puzzle.
