Abstract
1,232,762. Photographic apparatus. INTERNATIONAL BUSINESS MACHINES CORP. Feb.10, 1970, [March 27, 1969 (2)], No.6228/70. Heading G2A. Apparatus for exposing a photo-resist layer coated on the inner surface of a cylinder (42) Figs. 2, 3 (not shown), comprises a source of a non-divergent light beam, means to mount such a cylinder so that the light beam passes along the axis of the cylinder, and a conical mirror 18 positioned symmetrically about the axis for reflecting the light beam radially away from the axis so that the beam is directed towards the inner cylinder surface. A photo-resist coated cylinder is positioned by removing a cap 12 and sliding the cylinder down between an outer mask 10 and an inner mask (44). To initiate operation, a laser assembly 14 is turned on and, after a short interval, a start button 52 is depressed. This causes a hydraulic device 22 to raise the mirror 18 and a mirror 20, which reflects light radially in towards the mask 10 and the outer cylinder surface, to the top of the cylinder. A micro-switch, (not shown) signals when the mirrors are at the top of the cylinder, and a solenoid 38 is then energized to swing a shutter 40 away from opening 16 to begin the exposure sequence. During exposure the device 22 slowly lowers the mirrors 18, 20, until, another micro-switch senses that the mirrors are at the bottom of the cylinder, when the solenoid is de-energized. The cylinder is removed by lifting the cap 12. The laser assembly 14 includes a beam expander. It may be replaced by a mercury arc lamp and collimating lenses.
