Definitions

• the invention relates to a binder for the storage and filing of photographic films or the like, which binder comprises cover boards foldable towards each other like the covers of a book, and annular fastening means attached to one cover board, for the attaching of loose film pockets holding film strips to be filed, which strips for the viewing thereof are detached from said film pockets.
• the film negatives or transparencies are usually cut into sized portions stored in planar form. This storage method is favorable, since keeping the film flat for later viewing and copying is a suitable solution with respect to the aspect of preserving the film.
• the prior art comprises film pocket assemblies for the storage of photographic films cut into portions, such pockets comprising elongated film pockets of a transparent material and attached to each other in a side-by-side relation.
• the viewing of an individual film strip is fairly easy, because the whole film pocket assembly can be lifted in a spread out con ⁇ dition against a window or other light source.
• the detachment, however, of an individual film strip from the film pocket, as well as inserting it back into place is difficult.
• the storage of such film pocket assemblies also poses problems, because said assemblies cannot be placed e. g. into vertical disposition in accordance with normal storage methods. Covered binders for the keeping of negatives and transparencies are also known, which can be placed into a shelf preferably in a.
• Such a film binder preferably comprises loose pockets for the film strips, and said loose pockets are fastened one upon the other into the binder using conventional loop fastening means.
• pockets the film material is preserved rather well and the handling of each film strip is easy and protective - for the film material, because the individual film strip portions belonging to the same film usually are lose in the film pockets or are placed into an open simply folded pro ⁇ tective paper.
• At least one cover board part comprises means for facilitating the viewing of pictures.
• Said means facilitating the viewing constitute a viewing device, which to its function is integrally connected to the film binder, said viewing device having a viewing plane for the inspection of any individual film strip brought against it. The inspection of individual pictures or picture series can thus be accomplished as a continuous operation so, that each film strip is viewed immediately against a facilitating device.
• Each film strip is picked out of its storage pocket separately only for the time of viewing and without removing said strip from the immediate vicinity of the corresponding storage pocket.
• the binder comprises several film pockets fastened one upon the other in the same fastening loops, the specific storage pocket for the film being viewed is always at hand during the viewing, so that no mixing up can occur. For the next viewing another storage pocket is turned up so, that this pocket is topmost immediately adjacent to the viewing device. Due to the invention a safer maintenance of order is achieved and at the same time the actual viewing and after-use of the films is facilitated.
• the back cover board of the storage and filing binder comprises a partly transparent portion or a brightly light reflecting portion, respectively, against which portion the film to be viewed is laid.
• a viewing plane which is coated with a light-coloured after-glowing paint.
• a preferred embodiment of the invention comprises a light box having a partly light diffusing viewing plane, a light source, an energy source and a light switch.
• the binder 1 of the embodiment disclosed in the figure thus comprises a back piece 4 besides cover boards 2, 3, which are foldable against each other.
• fastening loops 6 for the film pockets 5 are attached to one of the covers boards 3.
• viewing facili ⁇ tating means are attached to the binders.
• said means comprise a viewing device using actively produced light, i. e. a light box 7 having, besides a partly transparent viewing plane, also a light source 9.
• the viewing plane 8 proper is preferably light diffusing, whereby the light emitted from at the simplest one spotlike light source 9 will be distri ⁇ ubbed as evenly as possible.
• the light source 9 is preferably formed by a series of incandescent lamps or light emitting diodes drawing power from a battery not shown.
• An alternative light source comprises a discharge lamp.
• the viewing plane is further extended with a blackened non-transparent portion 11, so that the actual exposure proper will fall only on the picture portion of the film strip to be viewed, and will not disturb the clarity of any text portion possibly connected with the film strip.
• a light box drawing power from a separate battery -preferably al ⁇ o comprises a switch 10, which in one embodiment is arranged so, that the light goes on when the cover is opened and goes out when the cover is closed, respectively.
• the light box 7 is essentially integrated with one cover board 3 of the binder, but the scope of the invention covers also an embodiment, where the viewing device 7 is attached to a separate support board, which like a film pocket will be fastened to the fastening loops 6.
• the viewing device can be detached from the binder and can be used independently, or e. g. in the connection with a plurality of conventional binders.
• the scope of the invention further comprises an embodiment, where the viewing device further comprises fastening means for the film strips.
• the film strip to be viewed can be attached to the viewing plane, whereby the whole binder arrangement can be hung on the wall, e. g. using hangers in the other cover board.
• the film pockets hanging from the fastening loops will hold the film strips to be stored, while the individual strip to be viewed will press against the viewing plane in a position which is pleasant for the user.
• the light box 7 attached to the binder is always at hand in the actual place of use, where it has an advantageous situation with respect to the viewing.
• a common light box placed on a separate board will again normally be situated in the most rele ⁇ vant binder or e. g. the one being prepared. Since the light box 7 is relatively fixedly attached to the binder or to a cor ⁇ respondingly large board the device will remain steadily in place. Thus the light box 7 itself can be made as small as pos ⁇ sible, without impairing its function.
