Abstract
Image scanning apparatus comprising a profiling surface; a feed mechanism for feeding a flexible radiation sensitive record medium across the profiling surface; a scanning system for scanning a modulated radiation beam across the record medium to expose the record medium; and a pressurizer operable simultaneously with the feed mechanism to apply a pressure difference across the record medium as it is fed across the profiling surface whereby the record medium engages the profiling surface and conforms with the shape of the profiling surface.
Claims13
Image scanning apparatus comprising a profiling surface;
- a feed mechanism for feeding a flexible radiation sensitive record medium across the profiling surface;
- a scanning system for scanning a modulated radiation beam across the record medium to expose the record medium;
- and a pressurizer operable simultaneously with the feed mechanism to generate a gas pressure difference between opposed sides of the record medium as it is fed across the profiling surface whereby the record medium engages the profiling surface and conforms with the shape of the profiling surface.
A method of loading a flexible radiation sensitive record medium into an image scanning apparatus, the method comprising feeding the flexible radiation sensitive record medium across a profiling surface;
- generating a gas pressure difference between opposed sides of the record medium by increasing the gas pressure on one side of the medium as it is fed across the profiling surface whereby the record medium engages the profiling surface and conforms with the shape of the profiling surface during feeding due to the increased gas pressure;
- and scanning a modulated radiation beam across the record medium to expose the record medium.
