Abstract:
A tight enclosure  1  receives by an airlock  2  virgin optical discs  3  sensitive to oxygen and packed in a tight packing  4 . These discs are came out of their tight packing  4  by a means  7 , introduced into a means of writing  6 , and again introduced into a tight packing  4   a  by a means of tight packaging  11 . Then they are got out of enclosure  1  through an airlock  5.

Description:
FIELD OF THE INVENTION  
       [0001]     The field of the invention is that of the distribution of the digital data, and more particularly that of the hiring of these data.  
       FORMER STATE OF THE ART  
       [0002]     One knows that there are optical discs of which matter is subjected to change of colouring under the influence of oxygen and/or the light, making them unsuitable with the reading at the end of a definite time, and/or a definite number of readings (apart from an accidental exposure to the light).  
         [0003]     These optical discs are designed for the hiring.  
         [0004]     They are sold in airtight or opaque envelopes which it is necessary to open to read the disc.  
         [0005]     The higher price of the discs and the price of their envelopes involves a higher cost of the stock.  
       GOAL OF THE INVENTION  
       [0006]     The purpose of the invention is to promote the hiring of these optical discs by removing the cost due to the stocking of the written discs of the former art.  
       SUMMARY OF THE INVENTION  
       [0007]     This goal is reached by integrating into an automatic autonomous distributing-machine of former art (application Fr 0307104) an enclosure tight with gases and/or opaque, free from oxygen, in which there are a stock of virgin discs, a means to writte these virgin discs, and a means to package the written discs in an individual enclosure tight and/or opaque, free from oxygen.  
         [0008]     An autonomous data distributing-machine includes at least: 
        a means of mass memory,     a means to read this mass memory,     a means to choose data from this mass memory,     a means to write on separate supports the chosen data,     a reserve of separate supports,     a means of availability of the separate support containing the data chosen, 
 
 a separate data support being a portable autonomous means having at least a means of information storage, and being able to be put in relation with the means to write the data chosen, for example an optical disc.

       DETAILED DESCRIPTION  
       [0000]     First Preferred Realization ( FIG. 1 ).  
         [0042]     An enclosure  1 , airtight and free from oxygen, has at least: 
        an airlock of entrance  2 , having a outside door  2   a  and an interior door  2   b , by which it is possible to introduce virgin discs  3  into their airtight packing  4 , individual or collective, free from oxygen;     an airlock of exit  5 , having an outside door  5   a  and an interior door  5   b , by which will come out the written discs  3   a , in their individual airtight packing  4   a  free from oxygen;     a means of writing  6  on the virgin discs  3  of the selected data;     a means of extraction  7  of the virgin discs  3  of their packing seals  4 , collective or individual, for example airtight gloves  7   a  accessible from the outside of enclosure  1  and making it possible to handle simple tools  8  located in the enclosure, for example a cutter;     a means of storage  9  of the virgin discs  3  got out of their packings  4 ;     a means of handling  10 , for example a carriage provided with devices of gripping and being able to move from airlock of entry  2  to the airlock of exit  5 , to introduce the virgin discs  3  extracts of their packing into the means of writing  6 , and to come out the written discs  3   a  from it;     a means of individual packing  11  locking up the written discs  3   a  in an individual airtight packing  4   a  free from oxygen;     a stock  17  of tight individual packing  4   a , or materials and means to constitute such tight individual packing  4   a , possibly in a airlock  17 ;     a means  12  of extraction of the air introduced into the airlock of entry  2  and exit  5 , for example a vacuum pump;     an inert gas stock  13 . 
 
 Second Preferred Realization 
       
 
         [0053]     This realization differs from the preceding realization in what: 
        the airlock of entry  2  has a form and dimensions such as airtight packing  4  can be contained there exactly,     the airtight packing  4  consists of a container  4   b  rigid or semi-rigid having a lid  4   c,       the residual air between this airlock  2  and the container  4   b  is driven out by a neutral gas circulation, possibly associated with an extraction of the air by means  12 , a means  14  of the airlock  2  opens and shuts the lid  4   c  to make it possible by means of handling  10  to use the virgin discs  3 . 
 
 of tight packings  4   a  for the packaging of the written discs  3   a  
 
 Third Preferred Realization 
       
 
         [0057]     This realization differs from the preceding achievements in what: 
        the shape and dimensions of the airlock of entrance  2  are such as the lid part of the container  4   b  adapts very exactly and in a tight way with the interior door frame  2   b  of this airlock of entrance  2 ,     the air contained between the lid  4   c  of the container  4   b  and the interior door  2   b  of the airlock  2  is driven out by a neutral gas circulation, possibly associated with an extraction of the air by means  12 ,     the connection between airlock  2  and the container  4   b  is ensured by a device  15  prohibiting the removal of the container if the interior door  2   b  and the lid  4   c  of the container are not closed,     the means  14  of the airlock  2  opens and shuts the lid  4   c  of the container  4   b  to allow by means of handling  10  to use the virgin discs,     the device  15  forbids the opening of the interior door  2   b  of the airlock  2  if the sweeping by the neutral gas were not done. 
 
 Fourth Preferred Realization ( FIG. 2 ) 
       
 
         [0063]     This realization differs from the preceding achievements in what: 
        the shape and dimensions of the airlock of entrance  2  are such as the lid part of the container  4   b  adapts very exactly and in a tight way with the frame of the external door of this airlock of entrance  2 ;     the air contained in airlock  2 , between the lid  4   c  of the container  4   b  and the interior door  2   b  of airlock  2  is expelled by a neutral gas circulation, possibly associated with an extraction of the air by means  12 ;     the connection between airlock  2  and the container  4   b  is ensured by a device  15  prohibiting the removal of the container  4   b  if the interior door  2   b  of airlock  2  and the lid  4   c  of container  4  are not closed;     the means  14  of the airlock  2  opens and shuts the lid  4   c  of the container  4   b.  
 
 Fifth Preferred Realization ( FIG. 1 ) 
       
 
         [0068]     This realization differs from the preceding achievements in what: 
        there exists in the tight enclosure  1 , or out side of this one, in a derived circuit  16  recycling the atmosphere of this enclosure  1 , a means to fix oxygen, for example an oxydable simple element;     there exists in the tight enclosure  1 , or in the derived circuit  16 , an oxygen detector possibly connected to a warning system. 
 
 Sixth Preferred Realization ( FIG. 1 ) 
       
 
         [0071]     This realization differs from the preceding achievements in what: 
        the means of writing  6  on the independent supports virgin  3  is in an airlock  6   a  allowing its extraction without introduction of air into the tight enclosure  1 . 
 
 Seventh Preferred Realization 
       
 
         [0073]     This realization differs from the preceding achievements in what: 
        when the virgin discs  3  are in individual packing  4  tight and free from oxygen, this packing is opened and re-used like packing of the written discs  3   a , for example, packing  4  of discs  3  has a diameter largely higher than that of the discs  3  contents and their sealing is assured close to their periphery;     under these conditions means  7  of extraction of discs  3  of their packing eliminates the periphery ensuring the sealing by leaving around disc  3  a sufficient space to ensure a new sealing;     the remaining elements of packing  4  are transferred towards means  11  of packaging of the written discs  3   a  which places a disc written between the said remaining elements and ensures the sealing of the new packing by a welding of these elements to their periphery.
