Abstract
Abstract Images projected by an image-focusing optical mechanism including a display unit such as a CRT display are photographed on a photosensitive medium such as a photographic film. First, the optical mechanism is positioned in a reference position. Then, the optical mechanism is displaced by successive intervals while photographing the images successively on the photosensitive medium at respective areas thereon with the optical mechanism. After all of the images have been photographed, the optical mechanism is positioned in the reference position again in preparation for photographing images on a next photosensitive medium.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
205 words
An apparatus for photographing images displayed by a display unit on a photosensitive medium, comprising a first feed mechanism for feeding the photosensitive medium to a predetermined position; an image-focusing optical mechanism for photographing the images on the photosensitive medium fed by said first feed mechanism; an image positioning mechanism for positioning the photosensitive medium and delivering the photosensitive medium at predetermined intervals while the images are successively photographed on the photosensitive medium by said optical mechanism, said image positioning mechanism comprising a constant feed roller pair for feeding the photosensitive medium in a predetermined length and a pair of guide members, said feed roller pair being disposed in confronting relation to said first feed mechanism, one of said guide members facing said optical mechanism and having an opening defined therein for passage therethrough of light from the displayed images, said image positioning mechanism being arranged to deliver the photosensitive medium toward said first feed mechanism while holding one end of the photosensitive medium with said feed roller pair to allow said optical mechanism to photograph the images on the photosensitive medium in at least two frames thereon; and a, second feed mechanism for feeding the photosensitive medium after the images have been photographed thereon.
Claim 2
Independent Claim
205 words
An apparatus for photographing images displayed by a display unit on a photosensitive medium, comprising a first feed mechanism for feeding the photosensitive medium to a predetermined position; an image-focusing optical mechanism for photographing the images on the photosensitive medium fed by said first feed mechanism; an image positioning mechanism for positioning the photosensitive medium and delivering the photosensitive medium at predetermined intervals while the images are successively photographed on the photosensitive medium by said optical mechanism, said image positioning mechanism comprising a constant feed roller pair for feeding the photosensitive medium in a predetermined length and a pair of guide members, said feed roller pair being disposed in confronting relation to said first feed mechanism, one of said guide members facing said optical mechanism and having an opening defined therein for passage therethrough of light from the displayed images, said image positioning mechanism being arranged to deliver the photosensitive medium toward said first feed mechanism while holding one end of the photosensitive medium with said feed roller pair to allow said optical mechanism to photograph the images on the photosensitive medium in at least two frames thereon; and a, second feed mechanism for feeding the photosensitive medium after the images have been photographed thereon.
Claim 3
Dependent Claim
41 words
An apparatus according to claim 1, wherein said first feed mechanism comprises a pair of rollers and a first guide member which is angularly movable to feed the photosensitive medium selectively to said image positioning mechanism and said second feed mechanism.
Claim 4
Dependent Claim
40 words
An apparatus according to claim 2, wherein said first feed mechanism further comprises a second guide member disposed above said first guide member and slanted for guiding a leading end of the photosensitive medium toward said constant feed roller pair.
Claim 5
Dependent Claim
27 words
An apparatus according to claim 1, wherein said image focusing mechanism includes a stepping motor directly coupled to said constant feed roller pair for rotating the same.
Claim 6
Dependent Claim
48 words
An apparatus according to claim 1, wherein said guide members of said image positioning mechanism are spaced from each other by a gap which is greater than the thickness of said photosensitive medium and smaller than the depth of field of a focusing lens of said optical mechanism.
Claim 7
Dependent Claim
41 words
An apparatus according to claim 5 wherein said optical mechanism includes the display unit and a focusing lens, and is displaceable in a direction substantially normal to the direction in which the photosensitive medium is delivered in said image positioning mechanism.
Claim 8
Dependent Claim
22 words
An apparatus according to claim 1 or 2, further including a single drive source for actuating said first and second feed mechanisms.
Claim 9
Dependent Claim
25 words
An apparatus according to claim 1, further including a support member supporting said first feed mechanism, said image positioning mechanism, and said second feed mechanism.
Claim 10
Dependent Claim
64 words
An apparatus according to claim 1, further including a housing in which said first feed mechanism, said optical mechanism, said image positioning mechanism, and said second feed mechanism are accommodated, and a cable extending out of said housing for supplying an image signal to said optical mechanism, said housing including light-shielding means disposed around said cable for preventing extraneous light from entering said housing.
