Abstract

Provided is a structure forming apparatus, including: a roller provided to be rotatable, having a length in an axial direction of the rotation, and capable of transmitting an energy beam; a retaining member arranged to face the roller such that a slit region having a length in the axial direction is formed between the retaining member and the roller, and capable of retaining a material to be cured by energy of the energy beam at least in the slit region; an irradiation unit configured to selectively radiate the energy beam to the slit region through the roller to cure the material so that a sheet-like structure is formed; and a take-up reel configured to take up the sheet-like structure thus formed.

First claim

The invention is claimed as follows:

1. An apparatus, comprising:
a roller configured to be rotatable, wherein the roller has a length in an axial direction of rotation, and wherein the roller is further configured to transmit an energy beam;
a retaining member configured to:
face the roller, wherein a region between the retaining member and the roller comprises a slit region that has a length in the axial direction; and
retain a material to be cured by energy of the energy beam at least in the slit region,

wherein the energy beam is configured to be selectively radiated to the slit region between the retaining member and the roller, through the roller to cure the material to create a sheet-like structure, and
wherein the energy beam radiated to the slit region is configured to be transmitted through the retaining member;
a take-up reel configured to take up the sheet-like structure; and
a plurality of reflecting members configured to surround the energy beam transmitted through the retaining member after radiation of the transmitted energy beam through the roller.

2. The apparatus according to claim 1 , further comprising a supply reel configured to supply a base film between the roller and the retaining member.

3. The apparatus according to claim 2 , wherein the take-up reel is further configured to take up the sheet-like structure created on the base film together with the base film.

4. The apparatus according to claim 1 , further comprising an irradiation unit configured to generate a laser beam as the energy beam.

5. The apparatus according to claim 4 , wherein the irradiation unit comprises a scanning mechanism configured to scan the energy beam generated from a first laser light source in the axial direction.

6. The apparatus according to claim 1 , wherein the material comprises a photo-curable resin and contains a light absorber.

7. The apparatus according to claim 1 , further comprising a supply mechanism configured to supply the material to the slit region.

8. The apparatus according to claim 1 , further comprising a removal unit configured to remove an uncured material that adheres to the sheet-like structure output from the slit region.

9. The apparatus according to claim 8 , wherein the removal unit comprises a nozzle configured to suck the uncured material by vacuum action.

10. The apparatus according to claim 9 ,
wherein the removal unit further comprises a pipe-shaped mesh roller, wherein the mesh roller comprises a mesh member, wherein the mesh roller is configured to be rotatable on a transfer path for the sheet-like structure between the roller and the take-up reel, and wherein the mesh roller is further configured to apply tension to the sheet-like structure output from the slit region, and
wherein the nozzle is further configured to be arranged inside the pipe-shaped mesh roller, and wherein the nozzle is further configured to suck the uncured material through intermediation of the mesh member of the pipe-shaped mesh roller.

11. The apparatus according to claim 10 , wherein the nozzle is further configured to move along an axial direction of the pipe-shaped mesh roller.

12. The apparatus according to claim 1 , wherein the retaining member is made of a material configured to transmit the energy beam emitted from a laser light source,
wherein the apparatus further comprises:
a removal unit configured to remove an uncured material that adheres to the sheet-like structure output from the slit region; and
a transfer mechanism configured to transfer the sheet-like structure from which the uncured material has been removed by the removal unit up to the take-up reel while the energy beam emitted from the laser light source through the retaining member is input to the sheet-like structure from which the uncured material has been removed.

13. The apparatus according to claim 12 , wherein the plurality of reflecting members are further configured to support input of the energy beam from the laser light source to the sheet-like structure to be transferred by the transfer mechanism.

14. The apparatus according to claim 1 , further comprising an irradiation unit that comprises:
a lens configured to:
convert an equiangular motion of the energy beam reflected by a polygonal mirror into a uniform motion; and
emit the converted energy beam.

15. The apparatus according to claim 14 , wherein the polygonal mirror is configured to be rotated so as to scan the energy beam generated from a laser light source along the axial direction of rotation of the roller.

16. The apparatus according to claim 1 , further comprising:
a control unit configured to control power of the energy beam so that a depth of the sheet-like structure created in the slit region is successively controlled in an optical axis direction of the energy beam.

17. The apparatus according to claim 1 , wherein the plurality of reflecting members further are configured to be arranged between the retaining member and the take-up reel.
