A tripod mounting portion (not shown) is provided on the bottom surface of the camera body 101.

  In addition, on the left side when viewed from the front side of the camera body 101, a grip portion 102 held by a photographer at the time of shooting is supported rotatably with respect to the camera body 101 via a hinge portion 103 (see FIG. 3). Has been.

  The grip portion 102 is covered with a rubber material or the like so as to be easily gripped, and a release button 107 is provided on the front side of the upper surface portion, and an operation dial 203, A power button 204 and a reproduction key 205 are provided. A mode dial 206 and a custom key 207 are provided on the back side of the upper surface of the grip 102.

  In addition, an operation knob 208 for operating items displayed on the display screen of the display unit 201 and a menu key 209 for displaying a menu on the display screen are provided on the rear surface of the grip unit 102.

  FIG. 3 is an exploded perspective view of the camera body 101, the grip part 102, and the hinge part 103. As shown in FIG. 3, the hinge unit 103 includes a body side hinge plate 301 that is connected and fixed to the camera body 101, a grip side hinge plate 302 that is connected and fixed to the grip unit 102, and a hinge rotating unit 303 having a rotation mechanism. With.

  FIG. 4 is a view of the grip portion 102 as viewed from the camera body 101 side. In FIG. 4, a line extending in the lateral direction of the grip portion 102 through the rotation center of the grip portion 102 (rotation center of the hinge portion 103) is defined as an X axis 401.

  Further, a line that passes through the rotation center of the grip portion 102 orthogonal to the X axis 401 and extends in the vertical direction of the grip portion 102 is defined as a Y axis 402. In the present embodiment, the X axis 401 is disposed along the optical axis of the lens barrel 104.

  FIG. 5 is a left side view of the digital camera 100 as viewed from the front side. As shown in FIG. 5, the bottom surface portion 501 of the grip portion 102 is formed in an arc shape protruding downward, and the center of curvature of the arc shape coincides with the rotation center of the hinge portion 103.

  The relationship between the radius of curvature r of the arc shape and the distance a from the rotation center of the hinge portion 103 to the bottom surface of the camera body 101 is equal to or smaller than the distance a. That is, r ≦ a, and in this embodiment, r <a. For this reason, the bottom surface portion 501 of the grip portion 102 is disposed at a position that does not contact the seat surface of the tripod when the camera body 101 is fixed to a tripod (not shown).

  6A is a view showing a state in which the grip portion 102 is rotated 45 ° in the right direction in the drawing from the state of FIG. 5, and FIG. 6B is a view of the grip portion 102 from the state of FIG. 2 is a diagram showing a state in which the camera is rotated 90 ° in the right direction of the drawing with respect to the camera body 101. FIG.

  FIG. 6C is a perspective view showing a state in which the battery cover 702 provided on the bottom surface portion 501 of the grip portion 102 is opened and the battery 601 stored in the grip portion 102 is taken out in the state of FIG. FIG. FIG. 6D is a perspective view showing a state in which the grip portion 102 is rotated by 90 ° in the left direction of the drawing with respect to the camera body 101 from the state of FIG.

  As shown in FIGS. 6A to 6D, the grip portion 102 can be rotated in both the left direction and the right direction even when the camera body 101 is attached to a tripod. For this reason, the battery 601 accommodated in the grip part 102 can be taken out from either the front side or the back side of the camera body 101.

  FIG. 7 is a view of the digital camera 100 shown in FIG. 5 as viewed from the bottom side. As shown in FIG. 7, the above-described arc-shaped bottom cover 701 is disposed on the bottom surface portion 501 of the grip portion 102, and the battery 601 is removably accommodated inside the grip portion 102 in the bottom cover 701. A storage opening is formed. The storage port is covered with a battery lid 702 so as to be opened and closed.

  The battery cover 702 is supported so as to be rotatable in the opening / closing direction with respect to the bottom cover 701 via a rotation shaft 704 extending parallel to the X axis 401 on the camera body 101 side of the storage opening of the bottom cover 701. The battery lid 702 is provided with a lock knob 703 that prevents the battery lid 702 from being inadvertently opened in the closed state.

  FIG. 8 is a partially enlarged view showing a state in which the battery cover 702 is opened with respect to the bottom cover 701. As shown in FIG. 8, the battery 601 housed in the grip portion 102 is engaged with a locking piece 802 at the end in the take-out direction in a state of being biased in the take-out direction by a spring (not shown). It has been stopped.

  The locking piece 802 is rotatably provided between a position where it is locked to the battery 601 and a position where it is retracted from the battery 601. When the locking piece 802 is retracted from the battery 601, the battery 601 protrudes from the storage port by the biasing force of the spring, whereby the battery 601 can be easily taken out.

  Next, the battery lid 702 will be described in detail with reference to FIGS. 9 to 11. FIG. 9 is a perspective view of the battery lid 702 as seen from the back side. As shown in FIG. 9, the battery lid 702 includes a lid cover 901 that forms an exterior of the bottom surface portion 501 together with the bottom cover 701.

  The lid cover 901 is formed with a shaft hole 901a into which the rotation shaft 704 is inserted. The holding plate 902 regulates the movement of the lock knob 703 with the lock knob 703 sandwiched between the lid cover 901 and the cover plate 901. The pressing plate 902 is provided with a convex portion 903, and the convex portion 903 is disposed closest to the battery 601 among the components of the battery lid 702 when the battery lid 702 is closed.

  FIG. 10 is a perspective view showing a state in which the pressing plate 902 is removed from the battery lid 702 shown in FIG. As shown in FIG. 10, the lock knob 703 is biased by the coil spring 1001 in the direction in which the battery lid 702 is locked.

  FIG. 11 is a view seen from the direction of arrow A in FIG. As shown in FIG. 11, the back surface of the battery lid 702 is disposed so as to face the battery 601 housed in the grip portion 102, and is formed in a substantially flat shape in accordance with the end surface shape of the battery 601.

  As described above, the front surface side of the battery lid 702 (the bottom surface side of the grip portion 102) is formed in an arc shape protruding outward. Therefore, it is possible to reduce the size of the grip portion 102 by disposing the internal parts constituting the battery lid 702 in the region S indicated by the hatched portion in FIG. For this reason, in this embodiment, the lock knob 703 and the rotation shaft 704 are disposed in the vicinity of the Y axis 402, that is, in the vicinity of the center portion of the arc-shaped battery lid 702.

  As described above, in this embodiment, the grip portion 102 can be rotated with respect to the camera body 101 attached to the tripod regardless of the size of the seating surface of the tripod. Accordingly, even when the camera body 101 is attached to a tripod having a relatively large seating surface, the battery lid 702 provided on the bottom surface side of the grip portion 102 can be opened and closed, and the battery 601 can be easily replaced. It becomes.

  The configuration of the present invention is not limited to that exemplified in the above embodiment, and the material, shape, dimensions, form, number, arrangement location, and the like can be changed as appropriate without departing from the scope of the present invention. It is.
