Description

  The present invention relates to a protective case for an imaging device.

  2. Description of the Related Art Conventionally, a protective case capable of photographing in a state where an imaging device such as a video camera is housed, particularly a protective case for waterproofing (for example, a marine pack) is known. A conventional configuration will be described with reference to FIGS. FIG. 10 is a view showing a protective case for waterproofing a conventional video camera, and FIG. 11 is a view showing a base of the conventional protective case.

  Reference numeral 90 denotes a protective case, 91 denotes a video camera, 92 denotes a seal portion of the protective case opening, 93 denotes a base for attaching the video camera 91 to the protective case 90, 94 denotes a front cover of the protective case 90, and 95 denotes a front side This is a buckle for holding the cover 94 in a closed state. Reference numeral 96 denotes a tripod screw, and 97 denotes a lock member that engages with the protective case 90 in order to be fixed to the protective case 90.

  When the protective case 90 is used, after the video camera 91 is mounted on the pedestal 93, the position is determined by engaging the pedestal 93 and the protective case 90. The seal portion 92 is often composed of a rubber O-ring or the like. By closing the front cover 94, the seal portion 92 is compressed and crushed by a set amount to prevent external water from entering. For example, Patent Document 1 proposes a structure that is mounted on a pedestal that can be detachably attached to a protective case using a tripod mounting screw portion of a video camera main body in order to perform good shooting in a stable state.

JP-A-4-52630

  However, in the structure disclosed in Patent Document 1, since the pedestal and the video camera are fixed only at one place by the tripod mounting screw part, a floating occurs between the pedestal and the video camera, and the fixed fixation is ensured. I couldn't.

  Furthermore, recent video cameras have been downsized, and a tripod mounting screw portion of the video camera is often provided toward the corner of the camera. For this reason, floating is more likely to occur at the end of the pedestal far from the screw position, and abnormal noise is generated and the positional relationship with the operation keys is not matched.

  In view of the above-described conventional problems, the present invention is easy to attach to and detach from an imaging device, securely fixes the pedestal and the imaging device, and further attaches the pedestal to the imaging device so that the operation of the imaging device can be controlled. The purpose is to provide a case.

  In order to achieve the above object, a protective case according to one aspect of the present invention is a protective case capable of photographing in a state in which an imaging device is housed, and has a pedestal for fixing the imaging device, The pedestal includes a tripod screw and a claw portion that engages with the imaging device, and the claw portion is provided on the other side opposite to the one side of the pedestal on which the tripod screw is provided. It is characterized by being.

  According to the present invention, it is possible to provide a protective case that can be easily attached to and detached from an imaging device, securely fix the pedestal and the imaging device, and further control the operation of the imaging device by attaching the pedestal to the imaging device. Can do.

It is a figure which shows the base of the conventional protective case.

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

  FIG. 1 is an external perspective view of a waterproof case which is an example of an embodiment of a protective case of the present invention. Reference numeral 21 denotes a video camera (imaging device), 1 denotes a protective case, 2 denotes a seal portion of the protective case opening, 3 denotes a base for attaching the video camera 21 to be attached to the protective case 1, and 4 denotes a front cover of the protective case 1 Reference numeral 5 denotes a buckle for holding the front cover 4 in a closed state. The protective case 1 is used in the same manner as the protective case 90 described above.

  FIG. 2 is a perspective view showing the pedestal 3. Reference numeral 12 denotes a tripod screw for fixing the imaging device, 13 denotes a claw portion for fixing the imaging device, and 14 denotes a lock portion for fixing the protective case to the base.

  The claw portion 13 is provided on the other side opposite to the one side of the base 3 on which the tripod screw 12 is provided. As a result, the imaging device can be pulled in and fixed with the tripod screw 12, and the area far from the pedestal 3 can be pulled away from the tripod screw 12 with the claw portion 13 and fixed so as not to move in the direction.

  3 is a rear view when the pedestal 3 and the video camera 21 are fixed, FIG. 4 is a rear view when the pedestal 3 and the video camera 21 at the time of battery mounting are fixed, and FIG. 5 is a mounting of the pedestal 3 and the battery. It is a bottom view when the video camera 21 is fixed. Reference numeral 22 denotes a battery mounting portion provided in the video camera 21, 23 denotes a recess (engagement portion) for receiving the claw portion 13, and 24 denotes a battery for driving the video camera 21.

  The battery mounting portion 22 includes a mounting portion having a width A in a concave shape having a width B corresponding to the outer width of the battery 24. At this time, the recess 23 is provided within the width B of the battery mounting portion 22 and outside the range of the width dimension A. That is, the recess 23 is provided not in the area of the battery 24 that overlaps the entire area of the battery mounting portion 22 in the width direction, but in the area of the battery 24 that does not overlap with the battery mounting section 22 when viewed from the back side of the video camera 21. Yes. By providing the claw 13 and the recess 23 in this positional relationship, the battery 24 can be attached and detached while the pedestal 3 is attached to the video camera 21. Further, by providing the concave portion 23 in the battery mounting portion 22, if the battery 24 is mounted, the appearance from the appearance can be maintained.

  FIG. 6 is a cross-sectional view of the claw portion 13. The width D of the claw portion 13 is set smaller than the gap size C between the video camera 21 and the battery 24. Thereby, in the optical axis direction of the video camera 21, a space in which the claw portion 13 can be inserted is formed between the video camera 21 and the battery 24, so that the battery 24 is attached to the video camera 21. The base 3 can be attached and detached.

  FIG. 7 is a cross-sectional view similar to FIG. 61 is a switch (operation unit), and 62 is a key top. FIG. 7 is a configuration in which a switch 61 and a key top 62 are added to the configuration of FIG. 6, and the switch 61 can be pressed with the key top 62 in a state where the base 3 and the video camera 21 are mounted.

  FIG. 8 is a block diagram illustrating the configuration of the video camera of the embodiment. Reference numeral 71 denotes a lens, 72 denotes a shutter, 73 denotes a CMOS, 74 denotes a video processing unit, 75 denotes a recording device, and 76 denotes a control unit. When the claw part 13 presses the switch 63, the control part 76 changes the control state of the video camera 21. The change of the control state means that, for example, it is possible to perform optimal shooting in the case storage state by changing the white balance control suitable for underwater or changing the shooting mode to the underwater mode.

  FIG. 9 is a flowchart showing the operation in the video camera 21. When the power is turned on in step (denoted as S) 81, it is determined in step S82 that the switch 63 is pressed. If it is determined that the switch 63 has been pressed, the process proceeds to S83 to switch the video camera shooting mode to the underwater mode. Furthermore, in step S84, the switch 63 is monitored to be pressed, and the underwater mode is maintained when the switch 63 is pressed. When the depression of the switch 63 is released, the process escapes from the underwater mode in S85 and returns to S82 to monitor the depression of the switch 63. Here, the operation of S83 can be set to white balance control, not to change of the shooting mode, and to detection of attachment to the case.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
