(57) The retractable protective-screen (3) of a through-the- wall automated-teller machine
is in the form of a curved metal plate (10) guided at its side-edges (15), that is
driven through a slot (16) in a facia-wall (17) of the machine in both retraction
and extension via a single rack-and-pinion coupling (20,21). The rack (21) is a length
of powered-drive belting (22) clamped upon a foam-rubber backing (24) to the inside
of the plate (10) centrally of the two side-edges (15). Nylon blocks (18) clipped
to the four corners of the plate (10) run in two pairs or arcuate channel guide-pieces
(11,13), the blocks (18) to the front of the plate (10) running solely in the guide-pieces
(11) respectively of one pair mounted in front of the facia-wall (17), and the blocks
(18) to the rear of the plate (10) running solely in the guide-pieces (13) respectively
of the other pair mounted to the rear of the wall (17).
