ABSTRACT:
A document hold-down device in a copying apparatus includes a rectangular relatively stiff plate and a relatively stiff anchoring bar spaced from and parallel to the plate rear edge, the bar and plate being sandwiched between flexible synthetic resin sheets which envelope the bar and plate and are bonded to each other along their coinciding borders and preferrably along a hinge defining line intermediate the proximate edges of the sheet and bar. Fastening members releasably anchor the bar to the apparatus proximate the document support plate. Advantageously, to accommodate thick documents, a second bar is disposed between the anchoring bar and plate and enveloped between the flexible sheets which are bonded to each other along hinge lines along opposite sides of the second bar. A resilient sponge sheet may underlie the plate to accommodate uneven documents. A handle is provided at the plate outer edge and a device is provided for alternatively swinging the hold-down device toward open and closed positions or to retain it in an intermediate position.
