Abstract

Provided is an image exposure device capable of recording a favorable image and capable of decreasing the size of the device.
An image exposure device ( 10 ) includes an image display device ( 12 ) having pixels ( 13 ), a photosensitive recording medium support portion ( 21 ) that supports a photosensitive recording medium ( 14 ) for recording an image of the image display device ( 12 ) in a state in which an exposure surface ( 14 A) of the photosensitive recording medium ( 14 ) faces the image display device ( 12 ), and a transmitted light control portion ( 16 ) that is provided between the image display device ( 12 ) and the photosensitive recording medium support portion ( 21 ) and is formed by laminating three or more layers of transmission members ( 100 ) that have a plurality of openings ( 102 ) formed therein and transmit only light incident on the openings ( 102 ).

First claim

What is claimed is:

1. An image exposure device comprising:
an image display device having pixels;
a photosensitive recording medium support portion that supports a photosensitive recording medium for recording an image of the image display device in a state in which an exposure surface of the photosensitive recording medium faces the image display device; and
a transmitted light control portion that is provided between the image display device and the photosensitive recording medium support portion and is formed by laminating three or more layers of transmission members that have a plurality of openings formed therein and transmit only light incident on the openings,
wherein the plurality of openings is formed to be identical in size and location among the plurality of the laminated transmission members.

2. The image exposure device according to claim 1 ,
wherein the transmitted light control portion further includes at least any one selected from a slit, a fiber optic plate, or a capillary plate.

3. The image exposure device according to claim 1 ,
wherein the number of the layers of the transmission members is eight or less.

4. The image exposure device according to claim 1 ,
wherein the transmission member has a location determination hole for determining a location of each of the transmission members in a case of laminating the plurality of transmission members.

5. The image exposure device according to claim 1 ,
wherein at least one distance between adjacent transmission members is different from other distances between the transmission members.

6. The image exposure device according to claim 1 ,
wherein the image display device has two-dimensionally arrayed pixels, and
the image exposure device exposes an entire two-dimensional region of the exposure surface of the photosensitive recording medium at the same time.

7. The image exposure device according to claim 1 ,
wherein the image display device has one-dimensionally arrayed pixels, and
the image exposure device is configured to scan at least any one of the image display device or the photosensitive recording medium supported by the photosensitive recording medium support portion along a direction perpendicular to an array direction of the pixels of the image display device.

8. The image exposure device according to claim 1 ,
wherein the image display device has two-dimensionally arrayed pixels on a region having a smaller area than the exposure surface of the photosensitive recording medium, and
the image exposure device is configured to scan at least any one of the image display device or the photosensitive recording medium supported by the photosensitive recording medium support portion along an array direction of the pixels of the image display device and a direction perpendicular to the array direction of the pixels.

9. The image exposure device according to claim 7 ,
wherein, among exposure ranges by light from the pixels on a location at which the exposure surface of the photosensitive recording medium is supported, adjacent exposure ranges partially overlap each other.

10. An image exposure device comprising:
an image display device having pixels;
a photosensitive recording medium support portion that supports a photosensitive recording medium for recording an image of the image display device in a state in which an exposure surface of the photosensitive recording medium faces the image display device; and
a transmitted light control portion that is provided between the image display device and the photosensitive recording medium support portion and is formed by laminating three or more layers of transmission members that have a plurality of openings formed therein and transmit only light incident on the openings,
wherein a distance between the image display device and the transmission member closest to the image display device is equal to or more than a pixel pitch of the image display device.

11. An image exposure device comprising:
an image display device having pixels;
a photosensitive recording medium support portion that supports a photosensitive recording medium for recording an image of the image display device in a state in which an exposure surface of the photosensitive recording medium faces the image display device; and
a transmitted light control portion that is provided between the image display device and the photosensitive recording medium support portion and is formed by laminating three or more layers of transmission members that have a plurality of openings formed therein and transmit only light incident on the openings,
wherein a distance between the image display device and the transmission member closest to the image display device is equal to or less than 100 times a pixel pitch of the image display device.

12. An image exposure device comprising:
an image display device having pixels;
a photosensitive recording medium support portion that supports a photosensitive recording medium for recording an image of the image display device in a state in which an exposure surface of the photosensitive recording medium faces the image display device; and
a transmitted light control portion that is provided between the image display device and the photosensitive recording medium support portion and is formed by laminating three or more layers of transmission members that have a plurality of openings formed therein and transmit only light incident on the openings,
wherein, among the plurality of transmission members, a distance between the transmission member closest to the image display device and the transmission member farthest from the image display device is equal to or less than 100 times a distance of a pixel pitch of the image display device.
