Abstract
An original (1) to be reproduced is held in holder (11) and then the holder (11) is loaded into a projector (10). An image of the original (1) is projected on a layout sheet (18) which is placed on a digitizer (17). Data representative of the position of a desired region of the original (1) is then obtained. The holder (11) is then set in an image scanner (19) and photoelectric scanning is performed in accordance with the data.
Claims23
A method of placing an original in an image scanner to read an image of a desired area of said original, said method comprising the steps of:
- (a) placing an original in a holder which holds said original;
- (b) observing said original while said original is held by said holder and specifying a rectangular region which includes a desired area of said original in accordance with a predetermined scanning plan;
- (c) obtaining reference data which is indicative of the location and inclination of said rectangular region with respect to said holder;
- and
- (d) placing said holder in an image scanner while said original is held by said holder and adjusting said holder with respect to said image scanner in accordance with said data so that a side of said rectangular region is parallel to a scanning direction of said image scanner.
A system for placing an original in am image scanner to read an image of a desired area of said original, said system comprising:
- (a) means for placing an original in a holder which holds said original between two transparent members;
- (b) means for observing said original while said original is held by said holder and for specifying a rectangular region which includes a desired area of said original in accordance with a predetermined scanning plan;
- (c) means for obtaining reference data which is indicative of the location and inclination of said rectangular region with respect to said holder;
- and
- (d) means for placing said holder in an image scanner while said original is held by said holder and for adjusting said holder with respect to said image scanner in accordance with said data so that a side of said rectangular region is parallel to a scanning direction of said image scanner.
A method of recording data in an image scanner, said method comprising the steps of:
- (a) placing an original in a holder which holds said original between two transparent members;
- (b) storing data which includes information required for scanning said original to read an image of said original;
- (c) placing said holder in an image scanner while said original is held by said holder;
- and
- (d) after said step (b), reading said data by means of said image scanner to record said data in said image scanner.
A system for recording data in an image scanner, said system comprising:
- (a) means for placing an original in a holder which holds said original between two transparent members;
- (b) means for storing data which includes information required for scanning said original to read an image of said original;
- (c) means for placing said holder in an image scanner while said original is held by said holder;
- and
- (d) means for reading said stored data by means of said image scanner to record said data in said image scanner.
A system for scanning an image of an original to read said image according to scan data indicating a scanning condition for reading said image, said system comprising:
- (a) a holder for holding an original between two transparent members, said holder having a memory;
- (b) data generating means for generating data in accordance with an image of said original and a scanning plan prepared by an operator, said data generating means including means for recording said data in said memory of said holder;
- and
- (c) an image scanner for scanning said image of said original, said image scanner including:
- (1) a table for accepting said holder;
- (2) means for scanning said image of said original to read each scanning line of said image;
- (3) reading means for reading data stored in said memory;
- and
- (4) control means for controlling said image scanner according to said generated data.
A holder for holding an original in an image scanner, said holder comprising:
- (A) means for holding an original;
- said holding means including:
- (1) frame members which are connected to each other at their edges by a hinge, said frame members defining windows;
- and
- (2) transparent plates located in said windows;
- (B) a memory attached to said holding means for storing data, said memory being accessible from the exterior of said holding means.
A table for accepting an original thereon to read an image of said original by means of an image scanner, said table comprising:
- a hollow member having a window, said window having a shape corresponding to a shape of a holder for holding said original;
- a rotary table which is mounted in said window, said rotary table being rotatable with said original around a center thereof.
The table of claim 16, wherein:
- an angular index is located adjacent said window;
- and
- an indication mark is located on an edge of said rotary table so that the rotation of said rotary table can be determined by observing said angular index and said indication mark.
A method of recording data in a drum-type image scanner, said method comprising the steps of:
- positioning an original on a transparent base sheet;
- recording data on tape located at an edge of said base sheet, said data including positional information required for scanning an image of said original with a drum-type image scanner;
- winding said transparent base sheet having the original already positioned thereon onto a drum in such a manner that said tape partially or fully surrounds said drum;
- and
- rotating said drum around an axis while reading said data from said tape to record said data in said drum-type image scanner.
A system for recording data in a drum-type image scanner, said system comprising:
- means for positioning an original on a base sheet;
- means for recording data on tape located at an edge of said base sheet, said data including information required for scanning an image of said original with a drum-type image scanner;
- means for winding said base sheet on a drum with said tape partially or fully surrounding said drum;
- and
- means for rotating said drum around an axis while reading said data from said tape to record said data in said drum-type image scanner.
A drum for use in a drum-type image scanner for reading an image of an original, said drum comprising:
- a surface around which an original can be wound;
- and
- a memory circumferentially located on said surface for storing data.
A base sheet for holding an original while said base sheet is wound on a drum of a drum-type image scanner, said base sheet comprising:
- a transparent portion on which said original is positioned;
- and
- a memory physically attached to said transparent portion for storing data.
