Further, a lock detecting sensor (not shown) for detecting the engaging state with the locked part  2   a  is provided to the lock part  3   b  to detect whether the lid part  3  is closed or not. 
         [0043]    The destroying means or system  12  is configured as a shredder which shreds an object inserted between cutting parts  25  arranged adjacently opposed to each other. In the present embodiment, 2 sets of cutting parts  25  arranged adjacently opposed to each other are provided on top and bottom as shown in  FIG. 3 , and they are rotated by the driving means or system  13  including a motor to shred the recording medium retained by the retaining means or system  30 . A shredded material receiving part  26  for accommodating shredded material is provided below the destroying means or system  12 . 
         [0044]    Now, structure of the retaining means or system  30  is described in detail. Referring to  FIG. 4 , a perspective view of the safe with the lid part  3  in an opened state is illustrated. The retaining means or system  30  is provided with numerous retaining parts  31  for retaining recording media  40  along a longitudinal direction, and each retaining part is folded back at both sides in the longitudinal direction to form a bellows as a whole. Each retaining parts  31  is formed as a pocket to accommodate a single recording medium  40 . The retaining means or system  30  comprises a plurality of retaining parts  31  formed by adhering a transparent or translucent resin material on the surface side and a nonwoven fabric on the rear surface side. However, the material of the retaining means or system  30  is not limited to above. 
         [0045]    The retaining means or system  30  with numerous retaining parts  31  arranged along the longitudinal direction while folded back to form a bellows so that it becomes possible to accommodate numerous recording media  40  and the recording media  40  can be gathered in a single belt-like member, and therefore a shredding of the recording media by the destroying means or system  12  can be continuously conducted. 
         [0046]    As illustrated in  FIGS. 3 and 4 , a slit-like communication part  21  is formed on the bottom part dividing the storage part  10  and the lower section within the safe  1 , and the end part of the retaining means or system  30  retaining the recording medium  40  is set at the cutting part  25  of the destroying means or system  12 . Within the storage part  10 , a supporting part  22  for supporting the proximity of the end part of the retaining means or system  30  is provided. A guiding part  20  for guiding the retaining means or system  30  smoothly to the destroying means or system  12  comprises the communicating part  21  and the supporting part  22  together. Upon detecting unauthorized access to the storage part  10  in the safe  1 , the retaining means or system  30  accommodating the recording medium  40  guided to the destroying means or system  12  by the guiding means or system  20  can be immediately initiated to be shredded. 
         [0047]    Multiple means or systems can be considered as a means or systems to detect unauthorized access to the storage part  10  in the safe  1 . A theft detecting means or system (not shown) is provided inside the safe  1 , and such theft detecting means or system monitors multiple states to determine presence or absence of unauthorized access to the storage part  10 . When the theft detecting means or system determines that unauthorized access to the storage part  10  is present due to the change in one of the multiple states under observation, it operates to conduct shredding of the recording medium  40  by the destroying means or system  12 . 
         [0048]    As described above, the horizontal detecting part  14  is installed inside the safe  1 . Information on the inclination state of the safe  1  is sent from the horizontal detecting part  14  to the theft detecting means or system  12 . When the horizontal detecting part  14  detects the safe  1  to be inclined more than a prescribed angle, and the theft detecting means or system determines that the storage part  10  is illegally accessed by a theft, the theft detecting means or system activates the driving means or system  13  to shred the retaining means or system  30  retaining the recording medium  40  by the destroying means or system  12 . 
         [0049]    Further, the theft detecting means or system monitors residual electric charge of the power storage part  15 . In a normal state, the power storage part  15  maintains substantially full charge as the power supplying cord  4  is connected to the external power supply, but in occurrence of theft, the power supplying cord  4  is removed from the external power supply and the residual electric charge of the power storage part  15  gradually is reduced. When the residual electric charge of the power storage part  15  becomes less than a prescribed amount, the theft detecting means or system determines that the storage part  10  is accessed illegally by a theft, and activates the driving means or system  13  to shred the retaining means or system  30  retaining the recording medium  40  by the destroying means or system  12 . 
         [0050]    The theft detecting means or system also monitors the lock detecting sensor provided on the lock part  3   b  of the lid part  3 . When the lock detecting sensor detects that the locked state of the lock part  3   b  is released by other than the event of entering a valid password to the input part  5 , the theft detecting means or system determines that the storage part  10  is illegally accessed by a theft and then activates the driving means or system  13  to shred the retaining means or system  30  retaining the recording medium  40  by the destroying means or system  12 . 
         [0051]    Furthermore, the theft detecting means or system monitors entry of a password by the input part  5 . When an invalid password is entered to the input part  5  instead of the valid password more than prescribed times, the theft detecting means or system determines that the storage part  10  is illegally accessed by a theft and then activates the driving means or system  13  to shred the retaining means or system  30  retaining the recording medium  40  by the destroying means or system  12 . 
         [0052]    As described above, by monitoring multiple states by the theft detecting means, and activating the driving means or system  13  to shred and destroy the retaining means or system  30  retaining the recording medium  40 , if any states indicate unauthorized access to the storage part  10 , it is possible to detect theft without fail and reliably erase the recorded information by destroying the recording medium  40  upon theft occurrence. It is thereby possible to surely prevent the information kept in the safe  1  from being stolen. 
         [0053]    According to the present embodiment, the input part  5  is provided to the lid part  3  of the safe  1  to enter a password to the input part  5 . On the other hand, a function of the input part  5  can be provided to a smartphone so that a safe with higher security performance can be provided. A perspective view of a safe  1  comprising a smartphone as the input part  5  is illustrated in  FIG. 5 . 
         [0054]    Referring to  FIG. 5 , a recessed part  16  for accommodating smartphone  50  is provided on the lid part  3  of the safe  1 , and a connecting part  17  connectable with a connection terminal of the smartphone  50  is provided on the lower surface of the recessed part  16 . The smartphone  50  includes a connection terminal at the bottom, allowing to be retained in the recessed part  16  of the lid part  33  by inserting the connecting part  17  for connection. 
         [0055]    An application to function as the input part  5  is installed in the smartphone  50  in advance. By starting the application, a screen  51  constructed with a touch panel displays an icon  52  for input, and an input can be carried out by touching the screen. 
         [0056]    The smartphone  50  is assigned with a specific identification code, and the specific identification code assigned to the user&#39;s smartphone  50  installed with the application is stored in the safe  1  in advance. When the smartphone  50  is connected to the connecting part  17 , the application sends the specific identification code assigned to the smartphone  50  to the safe  1 , and the safe  1  discriminates whether the code is identical to the stored identification code or not. The safe  1  releases the locked state of the lid part  3  or locks the lid part  3  only when the identification code is identical to the recorded identification code and a valid password is entered from the smartphone  50 . 
         [0057]    From such structure, even if a smartphone other than the user&#39;s smartphone  50  is connected and the valid password is entered, the safe  1  cannot be locked and/or released unless the identification code meets to the stored identification code. Therefore, even if the password is leaked, the safe  1  could not be opened by anyone else without the smartphone  50  of the user, and it is possible to provide a safe  1  with even higher security. 
         [0058]    While the embodiments of the present invention are described above, application of the present invention shall not be limited to the present embodiment and various applications shall be construed within the scope of its technical aspect. For example, the destroying means or system  12  shall not be limited to a shredder and anything else capable of physically destroying the recording medium  40  along with the retaining means or system  30  can be used. Further, any means or system other than the described can be used as a means or system for detecting a theft.
