Abstract
Abstract Improved photographic film handling apparatus for use whth charged-particle beam equipment, such as electron microscopes, permits either photographic recording or direct viewing on a picture screen without removing the film handling apparatus from the beam path. The apparatus includes film supply means, a transport mechanism mounted in the beam path, and exposed film storage means. The photographic film, or other picture recording medium, is arranged in consecutive picture areas, each separated by a space sufficient to permit at least part of the chargedparticle beam to pass through a matching opening in the transport mechanism for reception by a direct view fluorescent viewing screen or by a television camera for multi-station remote viewing. The recording medium can be either in conventional roll film form, with openings cut in the film between consecutive picture areas, or in plate form, with the plates mounted on a link-type carrier having joints in the regions between the recording plates.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
214 words
In handling apparatus for supplying, transporting and storing media for recording images in charged-particle beam apparatus of the type that includes a supply means for sections of a recording medium, each section corresponding to a picture area, a transport mechanism positionable in a focal plane between a source of a charged-particle beam and a picture display sensing device for advancing the sections of the recording medium consecutively from the supply means into the path of the charged particle beam for exposure to the image generated by the beam, and means for storing the exposed sections of recording medium, the improvement comprising: a carrier means for arranging the sections of recording medium in consecutive order for advancement into the focal plane of the charged-particle beam by the transport mechanism and for separating the consecutive sections of recording medium by open spaces to permit at least part of the beam to pass through the carrier means to strike the picture display sensing device when said open spaces are advanced into the beam path, said carrier means comprising an elongated strip of photographic film having picture areas alternating lengthwise with cutout windows for permitting at least a portion of the charged-particle beam to pass through the film strip when the windows are advanced into the beam path.

Claim 3
Dependent Claim
62 words
The handling apparatus of claim 1 wherein the transport mechanism comprises: a picture stage positioned in the beam path for supporting the film strip in the focal plane of the beam, and a pressure plate for holding the film flat against the picture stage, both the picture stage and pressure plate having aligned windows matching the cutout windows in the film strip.
Claim 4
Dependent Claim
232 words
