enlarged character image generating means for generating an enlarged character image by enlarging the character image based on the predetermined ratio;
reduced character image generating means for generating a reduced character image by reducing the enlarged character image based on the predetermined ratio; and
editing means for generating an image for editing by composing the reduced character image with the low resolution image.
5. An image editing apparatus as claimed in claim 4, further comprising output means for outputting the enlarged character image and information regarding the low resolution image as an editing description file.
6. An image composing apparatus comprising composition means for obtaining a composite image by composing the enlarged character image with the original image, based on the editing description file output by the image editing apparatus of claim 5.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A method for producing ceramic green sheets by applying ceramic slurry on a long carrier film, said method comprising the steps of:
transferring the carrier film in the longitudinal direction thereof and in contact with a support roll;
removing foreign substances on the carrier film surface opposite to the carrier film surface which is in contact with the support roll, at the portion where the carrier film is in contact with the outer peripheral surface of said support roll, while supporting the carrier film by said support roll so that the transfer direction of the carrier film is changed by said support roll; and
forming a ceramic green sheet by applying ceramic slurry on at least one surface of the carrier film after said foreign substances have been removed.
2. A method for producing ceramic green sheets as claimed in claim 1, wherein the portion where the foreign substances are removed is located approximately at the longitudinal center of the carrier film portion where the carrier film is in contact with the outer peripheral surface of the support roll.
3. A method for producing ceramic green sheets as claimed in claim 1, wherein said ceramic slurry is applied on said carrier film surface from which the foreign substances have been removed.
4. A method for producing ceramic green sheets as claimed in claim 1, wherein the ceramic slurry is applied on the carrier film surface opposite to the carrier film surface from which the foreign substances have been removed.
5. A method for producing ceramic green sheets as claimed in claim 1, wherein the step of removing foreign substances includes using a foreign substance removal device that makes contact with a surface of the carrier film in order to remove the foreign substances from the carrier film.
6. A method for producing ceramic green sheets as claimed in claim 1, wherein the step of removing foreign substances includes using a foreign substance removal device that does not make contact with a surface of the carrier film to remove the foreign substances from the carrier film.
7. A method for producing ceramic green sheets as claimed in claim 1, wherein the transfer direction of the carrier film is changed by said support roll such that once the carrier film passes the support roll, the transfer direction of the carrier film is changed into the direction of approximately 90 with respect to the initial transfer direction.
8. A method for producing ceramic green sheets as claimed in claim 1, wherein the step of forming a ceramic green sheet by applying ceramic slurry is performed using at least one of a doctor blade method and an extrusion method.
9. A method for producing ceramic green sheets as claimed in claim 1, further comprising the step of directing the carrier film onto a backing roll provided downstream from the support roll and a foreign substance removal device used to perform the step of removing foreign substances from the carrier film.
10. A method for producing ceramic green sheets as claimed in claim 9, wherein the backing roll is arranged so that the carrier film surface from which foreign substances have been removed contacts the outer peripheral surface of the backing roll and the ceramic slurry is applied on the portion where the carrier film is in contact with the outer peripheral surface of the backing roll.
11. An apparatus for producing ceramic green sheets, said apparatus comprising:
a delivery roll arranged to feed a carrier film;
a transfer unit arranged to transfer the carrier film drawn out from said delivery roll in the longitudinal direction thereof;
a support roll arranged to support the carrier film on the outer peripheral surface thereof so as to change the transfer direction of said carrier film;
a foreign substance removal device disposed so as to remove the foreign substances on the carrier film surface opposite to the carrier film surface in contact with said support roll, at the portion where the carrier film is supported on the outer peripheral surface of said support roll; and
a ceramic-slurry applying device arranged to apply ceramic slurry on one carrier film surface from which the foreign substances have been removed by said foreign substance removal device, and to form a ceramic green sheet.
12. An apparatus for producing ceramic green sheets as claimed in claim 11, wherein said foreign substance removal device is disposed so as to remove the foreign substances on one surface of the carrier film approximately at the longitudinal center of the carrier film portion where the carrier film is contact with the outer peripheral surface of the support roll.
13. An apparatus for producing ceramic green sheets as claimed in claim 11, wherein said foreign substance removal device is arranged to contact a surface of the carrier film to remove the foreign substances from the carrier film.
14. An apparatus for producing ceramic green sheets as claimed in claim 11, wherein said foreign substance removal device is a noncontact-type foreign substance removal device that is arranged to remove the foreign substances on one surface of the carrier film without contacting the carrier film supported by the support roll.
15. An apparatus for producing ceramic green sheets as claimed in claim 11, wherein said support roll includes a drive roll coupled with a rotational driving source and said drive roll functions as at least one portion of said transfer unit.
16. An apparatus for producing ceramic green sheets as claimed in claim 11, wherein said ceramic-slurry applying device is arranged to apply the ceramic slurry on the carrier film surface from which the foreign substances have been removed.
17. An apparatus for producing ceramic green sheets as claimed in claim 11, wherein said ceramic-slurry applying device is arranged to apply the ceramic slurry on the carrier film surface opposite to the carrier film surface from which the foreign substances have been removed.
18. An apparatus for producing ceramic green sheets as claimed in claim 11, wherein the support roll is arranged such that the transfer direction of the carrier film is changed by said support roll such that once the carrier film passes the support roll, the transfer direction of the carrier film is changed into the direction of approximately 90 with respect to the initial transfer direction.
19. An apparatus for producing ceramic green sheets as claimed in claim 11, further comprising a backing roll provided downstream from the support roll and a foreign substance removal device and arranged to contact the carrier film.
20. An apparatus for producing ceramic green sheets as claimed in claim 19, wherein the backing roll is arranged so that the carrier film surface from which foreign substances have been removed contacts the outer peripheral surface of the backing roll and the ceramic slurry is applied on the portion where the carrier film is in contact with the outer peripheral surface of the backing roll.
