Abstract

An image recording apparatus which is arranged to project image rays from an image bearing medium onto a screen by the mirrors of a reader system and, as required, to record the image on an image recording medium by rotating a rotary mirror in a scanning manner. The apparatus includes a plurality of reflection mirrors for transmitting image rays reflected by the rotary mirror onto the image recording medium. The mirrors are disposed such that the optical axes of the image rays reflected from the rotary mirror to the final-stage mirror are located in one plane.

Claims

1. An image recording apparatus comprising:

a projection lens;

first reflection means rotatably disposed for reflecting light rays transmitted through said projection lens;

second reflection means for transmitting light rays reflected from said first reflection means onto an image display section; and

third reflection means for transmitting light rays reflected from said first reflection means onto an image recording section, said third reflection means including a plurality of mirrors, arranged to reflect light from said first reflection means successively from mirror to mirror and then to said image recording section, said plurality of mirrors being further arranged such that the optical axes of light rays reflected to each of said mirrors are located in substantially the same plane.

2. An image recording apparatus according to claim 1, wherein said first reflection means moves pivotally between a display position, at which said first reflection means reflects said light rays to said second reflection means, and a recording position, at which said first reflection means reflects said light rays to said third reflection means, said first reflection means being rotatable at said recording position at a constant speed so as to effect scanning exposure.

3. An image recording apparatus according to claim 2, wherein said second reflection means includes at least two mirrors, said two mirrors being opposed each other across the optical path of light rays which are reflected by said first reflection means at said recording position.

4. An image recording apparatus according to claim 3, wherein said display section includes a screen.

5. An image recording apparatus according to claim 1, further comprising:

a first assembly including said projection lens, said first reflection means and said image recording section; and

a second assembly including said display section and said third reflection means, said second assembly being swingably supported on said first assembly.

6. An image recording apparatus according to claim 5, wherein said image recording section includes a photosensitive member and processing means for processing said photosensitive member, said photosensitive member and said processing means being disposed in a third assembly which is swingably supported on said first assembly.

7. An image recording apparatus according to claim 5, wherein said photosensitive member and said processing means are detachable from said third assembly.

8. An image recording apparatus according to claim 6, wherein said second assembly and said third assembly are swingable in the same direction.

9. An image recording apparatus according to claim 1, wherein said first reflection means and said third reflection means are disposed in substantially the same plane, said display section being disposed on one side of said plane, said projection lens and said recording section being disposed on the opposite side of said plane.

10. A reader printer which is arranged to project an image from a film onto a screen and, as required, to project said image onto a photosensitive member, said reader printer comprising:

a first assembly including a projection lens and a rotary mirror;

a second assembly including a plurality of mirrors arranged to transmit light rays reflected by said rotary mirror onto said screen and said photosensitive member, said second assembly being supported on said first assembly to swing between closed and open positions; and

a third assembly including said photosensitive member and processing means arranged to cooperate with said photosensitive member to record and reproduce images projected onto said photosensitive member, said third assembly being rotatably supported on said first assembly and being detachable from said first assembly when said second assembly is placed in its open position.

11. A reader printer according to claim 10, wherein said photosensitive member and said processing means are detachable as a unit from said third assembly.

12. A reader printer according to claim 11, wherein said processing means includes means for electrostatically charging said photosensitive member and means for developing an electrostatic latent image formed on said photosensitive member.

13. In an image recording apparatus which is arranged to project image rays from an image bearing medium onto a screen by the mirrors of a reader system and, as required, to record said image on an image recording medium by rotating a rotary mirror in a scanning manner, a plurality of reflection mirrors arranged to transmit image rays reflected by said rotary mirror successively from mirror to mirror and then onto said image recording medium, said mirrors being disposed such that the optical axes of the image rays reflected from said rotary mirror to the last of said reflection mirrors are may be located in the same plane.
