     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0020]    Hereinafter, embodiments according to the present invention will be fully explained by referring to the attached drawings.  FIG. 1  is a perspective external view of a video camera for showing an outlook thereof, according to an embodiment of the present invention.  FIG. 2  is a perspective external view for showing the condition of opening a recording media cover for installing a recording medium, i.e., an optical disc, therein, within the video camera, according to the present invention.  FIG. 8  is an external perspective view of the video camera according to the conventional art. 
         [0021]    A video camera  1  shown in  FIGS. 1 ,  2  and  8  installs an optical disc  2  and a hard disc  3  there, as recording media thereof, and as is shown in  FIG. 2 , the optical disc  2  is installed within a main body of the video camera  1 , and the hard disc is held within a recording media cover  5  in one body, but in such a manner that it can be taken out by a special tool, such as, a precision driver, etc., for example. A diameter of the optical disc  2  is about 80 mm. 
         [0022]    On a housing  4  of video camera, in particular, on the side of the main body thereof, there are held an optic lens portion  6 , for optically inputting an object to be picked up therein, a view finder  7 , for displaying a picture, etc., when picking up an image or when reproducing, and a liquid crystal display portion  8  (not shown because it is disposed on the rear surface of the drawing), etc., through a mechanism frame (not shown in the figure). Further, on the housing  4  of the video camera main body is held the recording media cover  5 , which can be opened freely, for installing the optical disc  2  into the main body. Installation/discharge of the optical disc  2  into/from the video camera  1  can be done, in the similar manner to that of the conventional recording medium, by opening/closing the recording media cover  5 ; i.e., attaching or detaching it on a loading member of the disc  2  of the video camera  1 , in the structures. Herein, provision of a hard disc, i.e., one of the recording media, according to the present invention, it is provided within the recording media cover  5 , for the purpose of small-sizing of the video camera  1 . 
         [0023]    Within the video camera shown in  FIG. 8  is applied a hard disc of 1-inch type, and the sizes of the external configuration thereof are as shown in the figure. Also, the hard disc is fixed in a space defined by an optical disc cover  51  and a hard disc cover  52 . Among screws used for fixing the hard disc cover  52 , the screws in the direction perpendicular to a recording surface of the optical disc are three (3) in the pieces thereof,  58   a ,  62  and  63 , as shown in the figure. The screw  58   a  is provided from an outside of the hard disc cover  52 , while the screws  62  and  63  are provided from the side located on the optical disc cover  51 . The respective screws are disposed within an outside of the surface of the hard disc. 
         [0024]    In this manner, the size on a diagonal line is about 50 mm if it is the hard disc of the conventional 1-inch type, i.e., it is smaller than the diameter of the optical disc  2 . For this reason, it was possible to fix the hard disc cover  52 , without enlarging the video camera as a whole, even if providing the plural number of the screws in the direction perpendicular to the recording surface of the optical disc  2 . 
         [0025]    On the other hand, outlook sizes are shown in  FIG. 1 , of the external configurations of 1.8-inch type hard disc, which is to be applied, according to the present invention. In this manner, the size of the hard disc to be applied, according to the present invention, is about 89.2 mm, on the diagonal line thereof; it is larger than the diameter of the optical disc  2 . For that reason, in case when applying the 1.8-inch type hard disc, the entire of the video camera is enlarged if providing the screws in the plural number thereof, in the perpendicular direction to the recording surface of the optical disc  2 . 
         [0026]    Then, explanation will be made on the condition of installing the hard disc  3 , according to the present invention.  FIG. 3  is an external perspective view for shown the recording media cover  5  for installing the hard disc  3 , i.e., one of the recording media, according to the present invention.  FIG. 4  is a perspective view for showing the recording media cover  5  shown in  FIG. 3 , when seeing it from an inside thereof.  FIG. 5  is an exploded perspective view of the recording media cover  5 , according to the present invention. 
         [0027]    As is shown in  FIG. 5 , the recording media cover  5  is constructed with the optical disc cover  51  and the hard disc cover  52 , and the hard disc  3  is built in, being held between the optical disc cover  51  and the hard disc cover  52  in one body, in the structures thereof. Further, a rotation support member  55 , for rotationally open/close the recording media cover  5  with respect to the housing  4  on the side of the main body, is coincide or fitted with the recording media cover in one body, by means of screws not shown in the figure, or the like. Further, between the optical disc  2  and the rotation support member  55  is pasted a dumper member  59  for escaping it from contacting on the optical disc  2 . 
         [0028]    Herein, when photographing by means of the video camera  1 , it is held on a surface, on which the liquid crystal display is attached, and a handgrip band  9 , which is attached on the opposite surface thereof. Thus, it is held is such a manner; wrapping the hard disc cover  52  of the recording media cover  5  in the palm of a hand, while passing the hand through the handgrip  9  from below, and letting the handgrip band  9  to push the back of the hand, while attaching a tip of a finger on an upper side portion of the optical disc cover  51 . Since the usable modes of the video camera  1  can be expanded through enlarging the recording capacity of the hard disc  3  to be installed, as far as possible, then it is preferable to install a hard disc having a disc size as large as possible. However, although the position where the hard disc is disposed set at the handgrip portion, as was mentioned previously, for supporting the video camera  1 , but it is preferable to adopt such the structures that the hard disc to be installed is not limited by a manner of supporting by the hand. 
         [0029]    As is shown in  FIG. 3 , it is so constructed that the hard disc cover  52  can be slid into the direction shown by an outlined arrow, to be fitted or engaged with the optical disc cover  51 . Thus, the sliding direction for fitting is the direction perpendicular to the direction of gripping the handgrip. Behind the hard disc cover  52  in the sliding direction are provided a plural number of fitting claws  56 . The fitting claws  56  of the hard disc cover  52  are engaged with members  57  to be engaged with, which are provided on the optical disc cover  51 , thereby being held while positioning each other. After that engagement, it is screwed by a screw  58   b  at a front-end portion of the hard disc cover  52 , in the sliding direction thereof. In this manner, it is possible to escape from loosening of the engagement or fitting due to deformation, etc., by directing the engagement or fitting between the hard disc cover  52  at the handgrip portion, in which the hard disc is installed, and the optical disc cover  51 , into the direction, being perpendicular to the direction of griping by the hand, and thereby achieving a stable condition for insertion of the hard disc. 
         [0030]      FIG. 6  is an external view of the video camera, under the condition of removing the hard disc cover  52  therefrom. In the figure, an outer configuration of the optical disc and an outer periphery of the optical disc cover are shown by broken lines.  FIG. 7  is a view for showing, easily, the cross-section cut along A-A′ line in  FIG. 6 , under the condition of providing the hard disc cover thereon. 
         [0031]    In this manner, with removing the conventional screws  62  and  63  from the hard disc, and also engaging the fitting claw  56  with  57 , it is possible to coincide the outer peripheries of the hard disc cover and the optical disc cover, thereby achieving space saving of the members for fixing the hard disc. For that reason, it is possible to prevent the video camera as a whole from large-sizing thereof, with providing the hard disk of 1.8-inch type, stably, within the video camera, i.e., a hard disc having a size larger than the hard disc in the diameter thereof. In this manner, it is possible to achieve the both, i.e., enlargement of the recording capacity of the hard disc, and prevention of the video camera from large-sizing thereof. 
         [0032]    Further, the engagement between the optical disc cover  51  and the hard disc cover  52  is achieved by an engagement portion  60 , which is automatically rotated by the sliding. Herein, the fitting claw  56  is the member of engaging with the  57  without elastic deformation thereof, but on the contrary, the engagement portion  60  is also a claw-like member, but it is the member to be engaged with the optical disc cover  51  after being elastically deformed once when being engaged. In case of necessity of removing the hard disc  3  therefrom, due to, such as, a trouble in the hard disc  3 , for example, a special tool being sharp at the tip thereof, such as, a pincette or tweezers, is inserted into two (2) pieces of holes  61  provided on the damper member  59 , then the engagement between the optical disc cover  51  and the hard disc cover  52  can be removed through an opening provided on the optical disc cover  51 . This structure is for the purpose of inhibiting the user not to remove the hard disc  3 , erroneously, and it ensures the safety in relation to installation of the hard disc  3 . 
         [0033]    Also, comparing to the conventional video camera, the hard disc cover is fixed with using the claw-like engagement portion  60 , removing the screws that were used for fixing the hard disc, and therefore, it can be removed easily. With this, it is possible to ensure the easiness of maintenance in case when the hard disc must be removed, such as, when a trouble occurs in the hard disc, etc., for example. 
         [0034]    With such the structures as was mentioned above, it is possible to provide a small-size video camera, having reliability, making the hard disc removable to be repaired when it is in the trouble, while escaping the hard disc drive from being removed by the user, in particular, within the video camera installing the hard disc drive therein. 
         [0035]    While we have shown and described several embodiments in accordance with our invention, it should be understood that disclosed embodiments are susceptible of changes and modifications without departing from the scope of the invention. Therefore, we do not intend to be bound by the details shown and described herein but intend to cover all such changes and modifications that fall within the ambit of the appended claims.
