Abstract
Abstract The multiface image composer is suitable for use with a photographic enlarger, a projector, a slide projector and the like and it comprises a central image generator, a left side image generator and a right side image generator each arranged on a line crossing each other at right angle, half mirror means being arranged on the crossing point of the lines, the half mirror means being capable of being oriented at the angle of 45 deg. with respect to the line on which the image generator is arranged for directing the relected light of the image therefrom to a base plate on which a composite image is to be formed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
371 words
A multiface image composer comprising: a first image generator producing a first light ray having a first optical axis; a second image generator producing a second light ray having a second optical axis; a third image generator producing a third light ray having a third optical axis; said second and third image generators facing each other so that said second and third optical axes coincide; said first image generator being disposed between said second and third image generators so that said first optical axis intersects said second and third optical axes at a right angle to provide a common intersection point for said first, second and third optical axes; said first image generator facing towards a base plate with said common intersection point being disposed between said first image generator and said base plate; half mirror means being disposed at said common intersection point and being movable between first and second positions; said half mirror means permitting said first light ray to pass directly therethrough along said first optical axis towards said base plate when in both said first and second positions; said half mirror means, when in said first position, reflecting said second light ray so that said second light ray is deflected 90 degrees towards said base plate to coincide with said first light ray along said first optical axis to produce a first composite image, while simultaneously preventing deflection of said third light ray towards said base plate; said half mirror means, when in said second position, reflecting said third light ray so that said third light ray is deflected 90 degrees towards said base plate to coincide with said first light ray along said first optical axis to produce a second composite image, while simultaneously preventing deflection of said second light ray towards said base plate; and a lens being positioned on said first optical axis between said half mirror means and said base plate for focusing said first and second composite images, one at a time, onto said base plate so that a final composite image can be formed on said base plate by superposing said second composite image onto said first composite image after said first composite image has been formed on said base plate.
Claim 2
Dependent Claim
371 words
A multiface image composer comprising: a first image generator producing a first light ray having a first optical axis; a second image generator producing a second light ray having a second optical axis; a third image generator producing a third light ray having a third optical axis; said second and third image generators facing each other so that said second and third optical axes coincide; said first image generator being disposed between said second and third image generators so that said first optical axis intersects said second and third optical axes at a right angle to provide a common intersection point for said first, second and third optical axes; said first image generator facing towards a base plate with said common intersection point being disposed between said first image generator and said base plate; half mirror means being disposed at said common intersection point and being movable between first and second positions; said half mirror means permitting said first light ray to pass directly therethrough along said first optical axis towards said base plate when in both said first and second positions; said half mirror means, when in said first position, reflecting said second light ray so that said second light ray is deflected 90 degrees towards said base plate to coincide with said first light ray along said first optical axis to produce a first composite image, while simultaneously preventing deflection of said third light ray towards said base plate; said half mirror means, when in said second position, reflecting said third light ray so that said third light ray is deflected 90 degrees towards said base plate to coincide with said first light ray along said first optical axis to produce a second composite image, while simultaneously preventing deflection of said second light ray towards said base plate; and a lens being positioned on said first optical axis between said half mirror means and said base plate for focusing said first and second composite images, one at a time, onto said base plate so that a final composite image can be formed on said base plate by superposing said second composite image onto said first composite image after said first composite image has been formed on said base plate.
Claim 3
Dependent Claim
115 words
A multiface image composer according to claim 1, wherein said half mirror means includes first and second half mirrors disposed along said coinciding second and third optical axes; said first half mirror in said first position being at said common intersection point and being inclined 45 degrees with respect to said second optical axis, while said second half mirror in said first position is arranged perpendicular to said third optical axis; and said second half mirror in said second position being at said common intersection point and being inclined 45 degrees with respect to said third optical axis, while said first half mirror in said second position is arranged perpendicular to said second optical axis.
Claim 4
Dependent Claim
65 words
A multiface image composer according to claim 1, wherein a lamp, a group of dichroic filters and a diffusion box are arranged in a freely moveable color box of each of said image generators in a respective order from an outer side thereof toward said common intersection point, a thin space being provided in each said diffusion box into which further filters are detachably inserted.
Claim 5
Dependent Claim
36 words
A multiface image composer according to claim 3, wherein said group of dichroic filters of each image generator comprises a cyan section, a magenta section and a yellow section arranged in superposed relationship to each other.
