Definitions

• the present invention relates to an archiving holder for the conversion of images into electrical format, the archiving holder comprising at least one opening, in connection with which the image is arranged to be placed.
• a scanner comprising a scan- ning base, on which the image to be digitized is placed, and a large number of photoelectric transducer means.
• These photoelectric transducer means are used to generate an electrical charge or a voltage which is proportional to the intensity of light to which the transducer means is exposed. This electrical charge or voltage is further converted to digital format by an analog-to-digital conversion.
• This digital information can be stored in common memory means, such as a fixed disk, a CD-ROM, a digital versatile disk, or the like.
• the transducer means can be arrayed in either a row or a matrix.
• transducer means arrayed in a row When using transducer means arrayed in a row, the whole image area is read row by row, and this reading row by row is iterated, until the whole image area to be digitized has been scanned.
• transducer means arrayed in a matrix it is, in some applications, possible to convert even the whole image area at one conversion time.
• the number of transducer means will determine the maximum resolu- tion for digitizing the image. Particularly in the conversion of photographs and slides, a relatively high resolution should be used to achieve a conversion result of archival quality. For the conversion of drawings and text documents, also a lower resolution will normally be sufficient.
• the conversion may be either monochrome (black and white) or coloured, in which case the number of the transducer means is normally triple compared with the resolution of the image. In view of the present invention, however, the resolution of the conversion and the number of colours to be converted are insignificant.
• the conversion of the images to electrical format is made by placing the object to be converted in a holder fabricated for this purpose.
• This holder is provided with one or more apertures at the point where the image area of the image to be converted is placed.
• the image to be converted is normally attached at two or more points with an adhesive tape. After all the images to be converted at one time have been attached to the holder, the holder with the images is placed in the scanner. In some applications, the holder can still be placed in an input device which, in turn, is placed in a location reserved for it in the scanner. After this, it is possible to start the conversion of the images to electrical format.
• the holder and the possible input device are removed from the scanner and the images are detached from the holder.
• the detached images can now be returned to their storing location, such as image archives.
• the above-described arrangement comprises a number of disadvantages. It is difficult to place the images precisely in the right location in the holder, and the image can still be displaced, particularly at the attachment stage. Because of this displacement, the image converted to electrical format may be distorted. The correction of such a distortion by image processing software may be possible to some extent, but such correcting measures are often taken at the cost of the resolution of the image. Furthermore, the attachment of the image by various adhesive-based attaching means will damage both the image and the holder. For the same reason, the image is easily damaged when it is detached from the holder. The holders are opaque except for the image area, wherein at least a part of the edges of the image fails to be converted. Because it is laborious to attach and detach the images, the conversion of, for example, image archives to electrical format is slow and requires a lot of strenuous and precise manual work, which will also increase the costs of such archiving.
• the invention is based on the idea that the archiving holder is provided with fastening means which can be used to place the image in the correct position and to fasten it without separate attaching means and attaching stages.
• the present invention is primarily characterized in that the archiving holder consists of at least a first part and a second part which are placed on top of each other, that at least one opening is formed substantially in the same location in the first and second parts, and that at least one opening is provided with at least one fastening means for fastening the image in a detachable manner in the archiving holder.
• the present invention shows remarkable advantages over solutions of prior art.
• the archiving holder according to the invention it is possible to significantly reduce the need to attach and detach images, which will also reduce the probability of damaging the images.
• the images can be placed in the correct position more precisely than in solutions of prior art, wherein the quality of the electrical conversion is improved.
• the margin areas of the image are not covered, wherein the whole image area of the image can be converted to elec- trical format.
• the archiving holder according to the invention will also make it easier to archive the images, for example for the reason that the images can also be filed in these archiving holders without removing the images from them.

• Fig. 5 shows a detail of the archiving holder of Fig. 1 when the image to be converted is placed in its position.
• the archiving holder 1 consists of at least a first part 2 and a second part 3.
• the first part 2 is provided with one or more openings 4, at which the image to be converted is arranged to be placed.
• the second part 3 is provided with one or more openings 5 substantially at least partly at the openings 4 of the first part.
• the width of the openings 4 is arranged to be larger at the end of the first edge 6 (upper edge in the disposition according to Figs. 1 , 2 and 3) than at the end of the second edge 7 (lower edge).
• the width of the openings 5 in the second part is preferably dimensioned so that the openings 5 are narrower than the openings 4 of the first part on the side of the first edge 6.
• the width of the openings 4 of the first part and the openings 5 of the second part is substantially equal in the width direction.
• the first part 2 and the second part 3 of the archiving holder 1 according to the invention are placed on top of each other, after which they are attached to each other, for example, by glueing or by hot pressing.
• the adhesion is not extended all the way to the side edges of the openings 4, 5 but in such a way that a non-adhered (unglued) area is left at the side edge at that point of the circumference of the opening, where the opening 4 in the first part 2 of the achiving holder is wider.
• the image 9 to be placed at the opening 4, 5 can be inserted between the first part 2 and the second part 3 through this non-adhered area.
• This non-adhered area is shown by a broken line 10 in Fig. 1.
• Fig. 1 shows only one such broken line 10
• the other openings 4, 5 are provided with a corresponding non-adhered area.
• the image 9 to be converted can be pushed towards the second edge 7 (lower edge) of the openings 4, 5, until the image touches the second edge 7 of the opening 4 in the first part 2. Consequently, the image 9 to be placed in the archiving holder does not need to be attached by means of adhesive tapes, glueing or in another corresponding manner, but the image 9 will remain in its position, supported by the fastening means 8.
• the appended Fig. 4 further shows the structure of the archiving holder 1 according to an advantageous embodiment of the invention, as shown in Fig. 1.
• the figure shows the fastening means formed by the side edges of the openings 4, 5 in the first part 2 and the second part 3 of the archiving holder.
• These side edges of the openings 4, 5 are flexible to some extent when the image 9 is being placed in its position, to generate a slight compressive force on the image 9, keeping the image 9 in its position.
• the alignment of the image 9 in the correct position is primarily made by means of the side edges of the openings 4, 5 and the lower edge 7 of the opening 4 in the first part 2, which facilitates the correct positioning of the image 9 to be placed in the archiving holder.
• the archiving holder 1 can be provided with several openings 4, 5 to place several images 9 in the same archiving holder 1. These openings 4, 5 can be substantially equal in size in the same archiving holder, but they can also be different in size, if necessary. Furthermore, different archiving holders 1 may be provided with openings 4, 5 of different sizes. The openings 4, 5 in the archiving holder are preferably dimensioned for one or more images of standard size.
• Some standard sizes in general use include, for example, 36 x 24 mm, 60 x 45 mm, 60 x 60 mm, 60 x 70 mm, 60 x 80 mm, 60 x 90 mm, 90 x 120 mm and 4" x 5", but it will be obvious that the present invention is not limited solely on archiving holders 1 applying these image sizes.
• auxiliary fastening base (not shown) whose outer dimensions substantially comply with an image size intended to be inserted in the openings 4, 5 of the archiving holder, and which auxil- iary fastening base is provided, for example by applying the present invention, with the openings 4 of the first part and the openings 5 of the second part, whose sizes are dimensioned to comply with the special size in question.
• the image is thus placed in the auxiliary fastening base, after which the auxiliary fastening base is inserted in the archiv- ing holder 1 according to the invention.
• the first part 2 and the second part 3 of the archiving holder 1 are made of a transparent material, such as PVC plastic. Preferably, both parts are substantially of the same thickness, for example in the order of 0.25 mm or 0.15 mm.
• the archiving holder can also be made of a substantially opaque material, wherein, in some applications, the conversion result of the electrical conversion will be better, because the luminosity of the environment of the images is significantly lower than when using a transparent material.
• the archiving holder 1 is also provided with fixing means 12 which can be used to place the archiving holder 1 with the image(s) 9 onto the scanning base of a scanner (not shown).
• the fixing means 12 can also be used for archiving purposes to place the image in archives, in a file or the like.
• the archiving holder 1 is used, for example, in such a way that images to be converted are placed in the archiving holder 1 , after which the archiving holder 1 is placed either directly in the scanner or the archiving holder 1 is first placed in an input device which is placed in the scanner. After this, the image is converted to electrical format and stored in a way known as such. After the conversion step, the archiving holder 1 is removed from the scanner (and from the input device, if one was used). After this, the archiving holder can be placed in the archives without detaching the images or, if necessary, the images can be detached from the archiving holder. The above-presented steps are iterated until all the images have been converted to electrical format.
• the conversion of image archives to electrical format can be made significantly faster than when using solutions of prior art. Furthermore, the image archives are easier to use, because the images do not need to be detached and attached for the time of the electrical conversion. Furthermore, the images will not be damaged to a significant degree, even if the same images were often transferred from the archives to the scanner and back to the archives, as long as the images are stored in the archiving holder according to the invention.
• the openings can also be arranged, for example, in such a way that the image is placed in its position in the direction from the side edge.
• the fastening means 8 are preferably formed in con- nection with the upper and lower edges of the openings 4, 5, and the image is inserted against the side edge opposite to the insertion edge in the opening.
