Abstract
Apparatus for positioning sheet-like or strip-shaped originals in a photographic copying machine has a horizontal table with a large window for transmission of copying light and a removable or exchangeable holder on the table. The holder has a lower section which rests on the table and has a first opening in register with the window, an upper section one marginal portion of which is pivoted to the corresponding marginal portion of the lower section, which is movable to and from an operative position of overlap with the lower section and which has a second opening in register with the first opening when the upper section assumes its operative position, and an elastic hold-down device which is affixed to the upper side of the lower section and has an open-sided cutout in register with the first opening. An original is insertable between the hold-down device and the lower section so that a selected portion of the original registers with the cutout and the hold-down device biases three sides of such selected portion against the upper side of the lower section. The upper section has an L-shaped elastic biasing element one leg of which extends downwardly through the second opening and along the open side of the cutout to urge the remaining side of the selected portion of a properly inserted original against the lower section as soon as the upper section is moved to its operative position. The upper section can carry additional biasing elements which bear against the hold-down device along the remaining two closed sides of the cutout to urge the respective sides of the selected portion of the original against the lower section as soon as the upper section assumes its operative position.
