Next, the pressing portion 232 and the stopper portion 233 of the housing cover 210 will be described with reference to FIGS. 11 to 14. FIG. FIG. 11(a) shows the extended grip 200 with the grip cover member 203 in the closed position and the rear surface of the camera 100 to which it is attached. FIG. 11(b) shows the upper surface of the camera 100 (and the extended grip 200) shown in FIG. 11(a), and FIG. 11(c) shows the EE-EE cross section in FIG. The FF part is enlarged and shown. FIG. 12(a) shows the extended grip 200 with the grip lid member 203 slightly opened from the closed position and the rear surface of the camera 100 to which it is attached. FIG. 12(b) shows the upper surface of the camera 100 (and the extended grip 200) shown in FIG. 12(a), and FIG. 12(c) shows the GG-GG cross section in FIG. The HH section is enlarged and shown.

As shown in FIG. 11C, an electric circuit board 107 is arranged inside the camera 100 . A battery loading detection switch (battery loading detection member) 108 is provided near the battery chamber in the electric circuit board 107 . The battery loading detection switch 108 has a lever portion 108a, and when the camera lid member 110 is attached to the camera 100 as shown in FIG. is turned on by pushing the lever portion 108a. When the battery loading detection switch 108 is turned ON, a camera controller (not shown) such as a CPU or MPU mounted on the electric circuit board 107 detects that the camera 100 is loaded with batteries (stored in the battery chamber and the lid member is closed). ) is detected, and power supply from the battery to each unit in the camera 100 is started.

As shown in FIG. 11(c), when the extended grip 200 is attached to the camera 100 from which the camera lid member 110 has been removed, the pressing portion provided on the lid cover 231 of the grip lid member 203 closed at the closed position. 232 presses the lever portion 108 a of the battery loading detection switch 108 . As a result, the battery loading detection by the battery loading detection switch 108 is turned ON.

Further, as shown in FIG. 12(c), when the grip lid member 203 is opened from the closed position, the pressing portion 232 is separated from the lever portion 108a of the battery loading detection switch 108, so that the battery loading detection by the battery loading detection switch 108 is OFF.

Thus, the grip lid member 203 has the pressing portion 232 instead of the pressing portion of the camera lid member 110, and can turn on/off the battery loading detection by the battery loading detection switch .

Further, when the grip lid member 203 in the closed position is further pushed in the closing direction (+y direction) by an external force, the pushing portion 232 pushes the lever portion 108a of the battery loading detection switch 108 too much, and the battery loading detection switch 108 is closed. Failure to do so may result in malfunction. On the other hand, if the pressing portion 232 does not sufficiently press the lever portion 108a even though the grip lid member 203 is in the closed position, the battery loading detection switch 108 does not normally detect battery loading. Therefore, in this embodiment, the position of the pressing portion 232 in the ±y direction is set equal to the pressing portion of the camera lid member 110 .

FIG. 13(a) shows the bottom surface of the extended grip 200 (and the camera 100 to which it is attached) with the grip lid member 203 in the closed position.

FIG. 14(b) shows an LL-LL cross section in FIG. 14(a) and an enlarged view of the MM portion in the cross section.

As shown in FIG. 13(b), the battery holding member 106 provided in the battery chamber of the camera 100 engages with the end surface of the battery 104 housed in the battery chamber at the battery holding position to move the battery 104 into the battery chamber. keeping. The stopper portion 233 provided on the lid cover 231 of the grip lid member 203 in the closed position contacts the surface of the battery holding member 106 on the -z side, thereby moving the battery holding member 106 in the -z direction (holding release position). movement of the battery 104, that is, release of the holding of the battery 104 is restricted. This prevents the battery holding member 106 from being displaced from the battery holding position to the holding release position and the battery 104 from coming out of the battery chamber when an impact is applied to the camera 100 to which the extension grip 200 is attached.

As shown in FIG. 14B, when the grip lid member 203 is in the open position, the stopper portion 233 is separated from the battery holding member 106, so that the battery holding member 106 can move in the -z direction from the battery holding position. Become. When the user presses the battery holding member 106 in the −z direction with a finger to move it to the holding release position, the battery 104 is released from the holding and the battery 104 can be removed from the camera 100 .

As described above, the extended grip 200 of this embodiment includes the grip lid member 203 having the function of turning on the battery loading detection switch 108 and the function of restricting the movement of the battery holding member 106 in the same manner as the camera lid member 110. there is

Note that the pressing portion 232 and the stopper portion 233 may be provided on the lid base member 230 instead of the lid cover 231 .

As described above, the extension grip 200 of the present embodiment has the grip extension portion 204, thereby improving the holdability of the camera 100 for users with large hands. Moreover, since the extended grip 200 includes the grip lid member 203 having the same function as the camera lid member 110, the user can easily remove the battery 104 and the media 105 while the extended grip 200 is attached to the camera 100. can be inserted and removed.

Next, the convex portion 215 provided on the extended grip 200 of the present embodiment for countermeasures against drop impact will be described with reference to FIG. 15 . FIG. 15(a) shows the back of the camera 100 with the extended grip 200 attached. FIG. 15(b) shows the NN-NN cross section in FIG. 15(a) and shows an enlarged view of the PP portion in the cross section.

As shown in FIGS. 15A and 15B, the rear surface of the grip housing 201 is provided with a protrusion (protrusion) 215 protruding rearward (+z direction) therefrom. The convex portion 215 faces the outer surface of the lower end, which is the end on the bottom side of the exterior member 120 on the back side of the camera 100, near the dividing line 300 between the grip housing 201 and the grip lid member 203 ( or contact).

In FIG. 15A, the rear grip portion 102 of the camera 100 surrounded by a solid line is an area on which a part of the user's hand rests when the camera 100 is held by the user's hand. On both sides of the back grip portion 102 of the camera 100 are provided camera operation members 103 such as switches and dials for the user to give operation instructions to the camera 100 .

When the camera 100 to which the extended grip 200 is attached falls in the -y direction and the extended grip 200 collides with the ground or floor, the impact causes the grip housing 201 and the lid member 203 to flex, and the extended grip 200 moves toward the camera 100. There is a risk of getting into the inside of the exterior member. In particular, if the dividing line 300 between the grip lid member 203 and the grip housing 201 is provided on the rear surface of the extension grip 200 instead of the bottom surface, as in this embodiment, the grip lid member 203 is positioned inside the camera 100. There is a risk of slipping.
