Abstract
Abstract A flatbed facsimile apparatus is disclosed that is capable of functioning both as a facsimile transmitter and a facsimile recorder. The apparatus comprises a pair of film stations positioned in front of an objective lens on an optic axis. The first film station, adapted to hold processed X-ray film, is positioned adjacent a fluorescent lamp. The second film station, adapted to hold unexposed film, is mounted a distance closer to the objective lens. An oscillating mirror is positioned on the other side of the objective lens along the optic axis. A stationary mirror is removably mounted adjacent the oscillating mirror to reflect light beams onto an aperture plate. A phototube is positioned behind the aperture plate to generate a signal that is a function of the light intensity passing through the aperture. During the recording mode, the second mirror is removed to enable a recorder lamp to generate light signals and pass them through a second aperture plate which is directly in line with the oscillating mirror along the optic axis. A field lens is positioned adjacent the second aperture plate to reduce the spread of the beam between the aperture and the objective lens.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
236 words
A facsimile transceiver comprising: a first film station positioned adjacent a source of illumination; an objective lens positioned in front of said first film station along a focal axis; a movable mirror on the other side of said objective lens for reflecting light beams impinging thereon; first means for producing light signals and projecting said light signals onto said movable mirror, said first means comprising a recorder lamp and a first aperture plate positioned in front of said recorder lamp; second means for receiving light beams from said illuminated film station and generating signals that are a function of the light intensity received, either of said first or second means being positioned along the optic axis with respect to said movable mirror with the other of said first or second means being positioned at an angle with respect to said optic axis, said second means comprising a second aperture plate and a phototube positioned behind said second aperture plate; a stationary mirror detachably positioned along the optic axis with respect to said movaBle mirror to reflect light beams between said movable mirror and said means positioned at an angle to said optic axis, said stationary mirror being removable to enable light beams to pass between said movable mirror and said means positioned along said optic axis; and a second film station detachably positioned between said first film station and said objective lens along said optic axis.
Claim 2
Dependent Claim
236 words
A facsimile transceiver comprising: a first film station positioned adjacent a source of illumination; an objective lens positioned in front of said first film station along a focal axis; a movable mirror on the other side of said objective lens for reflecting light beams impinging thereon; first means for producing light signals and projecting said light signals onto said movable mirror, said first means comprising a recorder lamp and a first aperture plate positioned in front of said recorder lamp; second means for receiving light beams from said illuminated film station and generating signals that are a function of the light intensity received, either of said first or second means being positioned along the optic axis with respect to said movable mirror with the other of said first or second means being positioned at an angle with respect to said optic axis, said second means comprising a second aperture plate and a phototube positioned behind said second aperture plate; a stationary mirror detachably positioned along the optic axis with respect to said movaBle mirror to reflect light beams between said movable mirror and said means positioned at an angle to said optic axis, said stationary mirror being removable to enable light beams to pass between said movable mirror and said means positioned along said optic axis; and a second film station detachably positioned between said first film station and said objective lens along said optic axis.
Claim 3
Dependent Claim
24 words
The invention of claim 1 wherein said movable mirror comprises a planar mirror adapted to oscillate on an axis perpendicular to said focal axis.
Claim 4
Dependent Claim
28 words
The invention of claim 2 wherein said planar mirror is connected to a pivot arm which, in turn, is engageable to the cam surface of a rotating cam.
Claim 5
Dependent Claim
23 words
The invention of claim 1 further comprising a field lens positioned directly in front of said second aperture plate along said optic axis.
Claim 6
Dependent Claim
19 words
The invention of claim 1 wherein said objective lens is positioned a focal length from said first film station.
Claim 7
Dependent Claim
35 words
The invention of claim 1 wherein said second means is positioned at a 90* angle with respect to said optic axis and said stationary mirror is positioned at a 45* angle on said optic axis.
Claim 8
Dependent Claim
29 words
The invention of claim 6 wherein said first means is positioned on said optic axis at a distance from said movable mirror approximately twice that of said second means.
