Japanese Patent Laying-Open No. 2004-193678 (see paragraph numbers 0004 and 0006)

  In recent years, video cameras are in a state of diversifying information recording media with the development of digital recording technology. In other words, various media such as an optical disk, a hard disk, a memory card, and the like are mounted as recording media, not only video tapes, and a plurality of recording media are used in combination to facilitate recording and storage. It is improving.

  As described above, a video camera using a plurality of recording media improves the usability of recording and storage by properly using the recording media. However, each recording medium has a possibility of failure. Response to media maintenance is also required.

  In this regard, Patent Document 1 describes a video camera having a plurality of recording media, but does not consider maintenance of each recording medium.

  Furthermore, mounting a plurality of recording media in order to improve the usability of recording and storage of the video camera and increasing the capacity of the recording medium have a problem of increasing the size of the video camera. However, there is no description about the mounting position of each recording medium for downsizing the video camera and the consideration of the arrangement.

  Accordingly, an object of the present invention is to provide a video camera that can solve these problems.

  In order to solve the above problems, the present invention uses the configurations described in the claims as an example.

  According to the present invention, an easy-to-use video camera can be provided.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an external perspective view showing an outline of a video camera according to the present invention. FIG. 2 is an external perspective view showing a state in which a recording medium cover is opened in order to mount an optical disk as a recording medium in the video camera of the present invention. FIG. 8 is an external perspective view showing an outline of a conventional video camera.

  The video camera 1 in FIGS. 1, 2, and 8 is equipped with an optical disk 2 and a hard disk 3 as recording media, and the optical disk 2 is detachably attached to the main body of the video camera 1 as shown in FIG. 2. The hard disk is mounted and integrally held in the recording medium cover 5 so that it can be taken out by a special tool such as a precision screwdriver. The diameter of the optical disk 2 is about 80 mm.

  The housing 4 on the video camera main body side has an optical lens unit 6 for optically entering a subject, a viewfinder 7 for displaying images and the like during shooting and reproduction, and a liquid crystal display unit 8 (located on the back side of the drawing). Etc.) are held via a mechanical frame (not shown). Further, the casing 4 on the video camera main body side holds a recording medium cover 5 that can be opened and closed in order to mount the optical disc 2 on the main body. The optical disk 2 is attached to and detached from the video camera 1 by being attached to and detached from the optical disk mounting member of the video camera 1 by opening and closing the recording medium cover 5 in the same manner as the conventional attachment and detachment of the recording medium. Here, the hard disk 3 which is one of the recording media of the present invention is provided in the recording medium cover 5 in order to reduce the size of the video camera 1. The hard disk 3 is fixed by an engagement member and a locking member, which will be described later, so that the hard disk 3 cannot be detached from the video camera 1 during normal shooting.

  Here, the video camera 1 is supported when the video camera 1 is photographed by the handgrip band 9 attached to the mounting surface of the liquid crystal display device and the opposite surface. That is, the hard grip cover 52 of the recording medium cover 5 is wrapped in the palm of the hand through the hand from below the hand grip band 9, and the back side of the hand is pushed by the hand grip band 9 while keeping the tip of the finger along the upper side of the optical disc cover 51. It is a structure made by doing.

  Since the usage mode of the video camera 1 can be expanded by increasing the recording capacity of the mounted hard disk 3 as much as possible, it is preferable to mount a hard disk with as large a disk size as possible. However, as described above, since the hard disk is disposed at the hand grip portion that supports the video camera 1, the hard disk to be mounted is in a state of hindering the support by the hand when shooting the video camera 1. Need to avoid. On the other hand, the size that can be grasped by the palm of a standard person is approximately 80 mm, which is substantially equal to the size of the optical disc 2, so that the size of the optical disc cover 51 constitutes a predetermined shape required for placing the optical disc 2. The degree of design freedom is relatively limited, and the size of the optical disc cover is almost determined.

  The video camera of FIG. 8 shows a case where a 1-inch hard disk is used, and the outline dimensions of the hard disk are as shown. The 1-inch hard disk is fixed in a space formed by the optical disk cover 51 and the hard disk cover 52. Of the locking members (screws) used to fix the hard disk cover 52 to the optical disc cover 51, there are three screws 58a, 62, and 63 as shown in the drawing perpendicular to the recording surface of the optical disc 2. The screw 58a is installed so as to be screwed from the outside of the hard disk cover 52, and the screws 62 and 63 are installed so as to be screwed from the optical disk cover 51 side. Since the height direction of the 1-inch hard disk is 30 mm, it is shown that each screw is arranged on the outer peripheral side from the mounting projection surface of the hard disk. Therefore, it is shown that the hard disk cover 52 can be fixed without increasing the size of the entire video camera even if a plurality of screws are provided in a direction perpendicular to the recording surface of the optical disc 2.

  On the other hand, as shown in FIG. 1, the approximate external dimensions of the 1.8-inch hard disk used in the present invention is as large as 54 mm in the height direction, and the thickness of the hard disk 3 in the hard disk cover 52 for wrapping in the palm of the hand is 5 mm. Will expand the area that occupies. Furthermore, if a structure is formed in which the screws are tightened in the direction perpendicular to the recording surface of the optical disk 2 outside the 1.8-inch hard disk 3, the distance from the palm of the fingertip to the upper end of the optical disk cover 51 is further increased. As a result, it becomes difficult to support the video camera. Here, a description will be given of a structure that constitutes a video camera that can support a hard disk cover 51 by wrapping it with a palm while mounting a 1 / 8-inch hard disk.

  First, the mounted state of the hard disk 3 of the present invention will be described with reference to FIG. FIG. 3 is an external perspective view showing a recording medium cover 5 on which a hard disk 3 which is one of the recording media of the present invention is mounted. FIG. 4 is a perspective view seen from the inside of the recording medium cover 5 of FIG. FIG. 5 is an exploded perspective view of the recording medium cover 5 according to the present invention.

  As shown in FIG. 5, the recording medium cover 5 is mainly composed of an optical disk cover 51 and a hard disk cover 52. The hard disk 3 is configured to be sandwiched between the optical disk cover 51 and the hard disk cover 52 with the peripheral portion being held by the buffer member 54, and integrally incorporated in the recording medium cover 5. Further, the recording medium cover 5 integrally holds a rotation support member 55 for opening and closing with respect to the housing 4 on the main body side by screws or the like (not shown). Further, a buffer plate 59 for avoiding contact with the optical disc 2 is attached between the optical disc 2 and the rotation support member 55.

  Here, as shown in FIG. 3, the recording medium cover 5 is configured such that the hard disk cover 52 is slid in the direction indicated by the white arrow from the right direction of the drawing with respect to the optical disk cover 51. It has a structure that makes a contract with. That is, the sliding direction for engagement is a direction orthogonal to the direction of gripping the hand grip. A plurality of second engagement members (engagement claws) 56 formed inward from the outer peripheral edge of the hard disk cover 52 are provided on the rear portion of the hard disk cover 52 in the sliding direction. The engagement claw 56 of the hard disk cover 52 is engaged with a second engagement member (engaged recess) 57 provided on the optical disc cover 51 and positioned in the sliding direction. In a state in which both members are engaged, the hard disk cover 52 is screwed to the optical disc cover 51 by a screw 58b at the front end in the sliding direction. By fixing the hard disk cover 52 and the optical disk cover 51 in this manner, the fixing direction of the engagement member and the locking member is parallel to the sliding movement direction of the hard disk cover 52 and directed inward from both ends, and the hard disk By making the engagement between the hard disk cover 52 and the optical disk cover 51 in the hand grip portion on which the video camera 3 is placed perpendicular to the hand gripping direction, recording is performed by deformation of the hard disk cover 52 when the video camera 1 is supported during shooting. The loosening of the engagement of the medium cover 5 can be avoided, and the hard disk mounting state can be stabilized.

  FIG. 9 is an enlarged perspective view conceptually showing the engagement member 60 provided at the upper end of the hard disk cover 52 in order to strengthen the engagement between the hard disk cover 52 and the optical disk cover 51. The first engagement member (engagement collar) 60 provided on the hard disk cover 52 is positioned on the optical disk cover 51 by the second engagement member, and then the first engagement member (engagement) provided on the optical disk cover 51. This is a structure that presses against the heel portion 61 and engages with the to-be-engaged rod 61 by elastic deformation of the engagement rod 60.

  Further, as shown in FIG. 3, the hard disk cover 52 is screwed to the optical disk cover 51 by a screw 58 a at the lower end of the hard disk cover 52. In this way, the hard disk cover 52 is fixed to the optical disk cover 51 at a position near the outer peripheral end of the hard disk cover 52 because the engagement member and the locking member (screw) are combined to face each other. Adhering can be made more stable and strong while reducing the number of locking members.

  In addition, when the hard disk 3 that is not originally attached to and detached from the video camera 1 during general photographing needs to be removed due to a failure or the like, first, the hard disk cover 52 and the optical disk cover 51 are attached. After releasing the screwed screws 58a and 58b, a specific tool having a sharp tip such as tweezers is inserted into the two holes 61 provided in the buffer member 59 to be provided on the optical disc cover 51. The engagement rod 60 is elastically deformed through the opening, and the engagement between the optical disk cover 51 and the hard disk cover 52 is released, so that the hard disk cover 52 is slid from the optical disk cover 51 and the engagement of the engagement claws 56 is released. 52 and the optical disc cover 51 are separated, and the hard disk 3 is removed. Which enables the tooth. This configuration prevents the user from mistakenly removing from the recording medium cover 5 of the hard disk 3, and is intended to ensure safety related to the mounting of the hard disk 3.

  On the other hand, by eliminating the conventional screws 62 and 63 from the hard disk cover and engaging the engagement claw 56 with the engagement recess 57, the ease of maintenance when the hard disk cover 52 must be removed, such as when the hard disk 3 fails. Has achieved.

  The video camera 1 has a configuration in which the hard disc cover 52 and the optical disc cover 51 are fixed to each other in the vicinity of the outer peripheral end of the hard disc cover 52 by the opposing arrangement of the engagement member and the locking member while the 1.8-inch hard disk is mounted. It is possible to prevent the entire size of the apparatus from becoming large.

  In this way, it is possible to provide a video camera that has a large capacity of the hard disk, prevents an increase in the size of the video camera, and has reliability.
