Abstract
An image forming apparatus divides an original image into multiple areas depending on the magnification of copy and produces enlarged copies of the divided areas on sheets of copy paper sequentially, thereby obtaining a enlarged copy of the original larger than the paper size. For each divided area, copy paper of a smallest possible size necessary to copy the entirety of the divided area is selected. The original can be divided optimally based on the original size, copy paper size and magnification, or can be divided by excluding a specified region from the original.
Claims25
An image forming apparatus comprising:
- first setting means for setting an arbitrary magnification of copy;
- second setting means for setting the conjunct scale up copy mode in which an original is divided into multiple areas depending on the magnification which has been set and an enlarged copy of each divided area is produced on a sheet of copy paper;
- paper storage means including a plurality of paper storage devices for storing copy paper of different sizes;
- paper transportation means for feeding a sheet of paper from one of said paper storage devices selectively;
- and
- control means for controlling the paper feed operation in the conjunct scale-up copy mode for each divided area in such a manner that a paper storage device which stores copy paper of a smallest possible size necessary to copy the entirety of the divided area is selected.
An image forming apparatus comprising:
- first setting means for setting an arbitrary magnification of copy;
- second setting means for setting the conjunct scale-up copy mode in which an original is divided into multiple areas depending on the magnification which has been set and an enlarged copy of each divided area is produced on a sheet of copy paper;
- paper storage means including a plurality of paper storage devices for storing copy paper of different sizes;
- paper transportation means for feeding a sheet of paper from one of said paper storage devices selectively;
- and
- control means for controlling the operation in response to the emergence of a paper run-out state in a paper storage device, which is being selected, during the copy operation of divided original areas in the conjunct scale-up copy mode, in such a manner that all divided areas which are left unprocessed for copying are rendered the secondary division process based on a size of paper in a paper storage device that has not been selected previously and a copy of each newly divided area is produced on a sheet of paper fed from said paper storage device.
An image forming apparatus comprising:
- first setting means for setting an arbitrary magnification of copy;
- second setting means for setting the conjunct scale-up copy mode in which an original is divided into multiple areas depending on the magnification which has been set and an enlarged copy of each divided area is produced on a sheet of copy paper;
- and
- control means for controlling the operation in the conjunct scale-up copy mode in such a manner that if enlarged copied images derived from at least two divided areas can be laid out on a sheet of copy paper, the copies of said two areas are produced on the single sheet of copy paper.
An image forming apparatus comprising:
- first setting means for setting an arbitrary magnification of copy;
- second setting means for setting the conjunct scale-up copy mode in which an original is divided into multiple areas depending on the magnification which has been set and an enlarged copy of each divided area is produced on a sheet of copy paper;
- and
- control means for controlling the operation in the conjunct scale-up copy mode in such a manner that only divided areas larger than a specific size among all divided areas are designated as copy object regions.
An image forming apparatus comprising:
- first setting means for setting an arbitrary magnification of copy;
- second setting means for setting the conjunct scale-up copy mode in which an original is divided into multiple areas depending on the magnification which has been set and an enlarged copy of each divided area is produced on a sheet of copy paper;
- and
- control means for controlling the operation in the conjunct scale-up copy mode in such a manner that if at least one of the divided areas is a fragmentary area that is an area smaller than a specific size, the original is rendered the secondary division process such that said fragmentary area is distributed to the top, bottom, right and left edges of the original, and the original excluding the edge sections with the allocation of said fragmentary area is designated to be a copy object area.
An image forming apparatus comprising:
- first setting means for setting an arbitrary magnification of copy;
- second setting means for setting the conjunct scale-up copy mode in which an original is divided into multiple areas depending on the magnification which has been set and an enlarged copy of each divided area is produced on a sheet of copy paper;
- designation means for designating part of the original to be a specific region;
- and
- control means for controlling the operation in the conjunct scale-up copy mode, with a specific region being designated, in such a manner that the divided area corresponding to the specific region is copied on a priority basis.
A method of copying an original carried out with an image forming apparatus which includes a plurality of paper storage devices capable of storing copy paper of different sizes and paper feed means for feeding a sheet of copy paper from one of said paper storage devices selectively, said method comprising the steps of:

- dividing an original into multiple areas depending on the magnification which has been set;
- feeding a sheet of copy paper for each divided area by selecting a paper storage device which stores copy paper of a smallest possible size necessary to cop the entirety of the divided area;
- and
- producing an enlarged copy of each divided area on the sheet of copy paper which has been fed.
