  An interchangeable lens 11 is detachably attached to the camera body 3.

  The bottom cover 5 is made of plastic, has a substantially tray shape, and covers the bottom surface of the camera body 3. A hole 5a is formed in a substantially central portion of the bottom cover 5, and four screw insertion holes 5b are formed around the hole 5a.

  The attachment member 7 is made of metal, and includes a tripod seat (attachment portion) 71 and a seat plate (plate-like portion) 72.

  The tripod seat 71 has a substantially disk shape, and a boss 71a is formed at the center thereof. A female screw 71b is formed on the lower surface of the boss portion 71a. A camera fixing screw provided on a tripod (a member different from the camera body 3) (not shown) is screwed into the female screw 71b. Three female screws 71c are formed in the tripod seat 71 at equal intervals so as to surround the boss portion 71a.

  A hole 72 a is formed in the central portion of the seat plate 72. The hole 72 a is disposed to face the hole 5 a of the bottom cover 5. Female screws 72 b are formed at the corners of the seat plate 72. The female screw 72 b is disposed opposite to the screw insertion hole 5 b of the bottom cover 5. Around the hole 72a, three screw insertion holes 72c are formed at equal intervals. The screw insertion hole 72c is formed in a taper shape. The rigidity of the seat plate 72 is equal to or greater than the rigidity of the bottom cover 5.

  The screw 13 is inserted into the screw insertion hole 72c of the seat plate 72 and screwed into the female screw 71c of the tripod seat 71, so that the tripod seat 71 and the seat plate 72 are integrated. The head of the screw 13 is accommodated in the screw insertion hole 72c.

  The reinforcing plate 9 is made of metal. A hole 9 a is formed in the central portion of the reinforcing plate 9. The hole 9 a is disposed to face the hole 5 a of the bottom cover 5. The boss 71a of the tripod seat 71 is inserted into the hole 72a, the hole 5a, and the hole 9a. Screw insertion holes 9 b are formed at the corners of the reinforcing plate 9. The screw insertion hole 9 b is disposed opposite to the screw insertion hole 5 b of the bottom cover 5. The rigidity of the reinforcing plate 9 is equal to or greater than the rigidity of the bottom cover 5.

  The screw 14 is inserted into the screw insertion hole 9b of the reinforcing plate 9 and the screw insertion hole 5b of the bottom cover 5, and is screwed into the female screw 72b of the seat plate 72, whereby the seat plate 72 and the reinforcing plate 9 are connected to the bottom cover 5. It is combined in a state that sandwiches.

  Next, assembly of parts other than the camera body 3 of this camera will be described.

  First, the boss portion 71 a of the tripod seat 71 is inserted into the hole 72 a of the seat plate 72. The tip of the boss 71a inserted into the hole 72a protrudes from the hole 72a.

  Next, the screw 13 is inserted into the screw insertion hole 72 c of the seat plate 72 and further screwed into the female screw 71 c of the tripod seat 71. As a result, the tripod seat 71 and the seat plate 72 are integrated.

  Thereafter, the boss 71 a of the tripod seat 71 protruding from the hole 72 a is inserted into the hole 5 a of the bottom cover 5, and the seat plate 72 is placed on the bottom cover 5. When the seat plate 72 is placed on the bottom cover 5, the tip of the boss 71a of the tripod seat 71 protrudes from the hole 5a.

  Next, the boss portion 71 a of the tripod seat 71 protruding from the hole 5 a is passed through the hole 9 a of the reinforcing plate 9, and the reinforcing plate 9 is applied to the bottom surface of the bottom cover 5. At this time, the screw insertion hole 9b of the reinforcing plate 9b is aligned with the screw insertion hole 5b of the bottom cover 5.

  Thereafter, the screw 14 is inserted into the screw insertion hole 9 b of the reinforcing plate 9 and the screw insertion hole 5 b of the bottom cover 5, and further screwed into the female screw 72 b of the seat plate 72. As a result, the bottom cover 5 is sandwiched between the seat plate 72 and the reinforcing plate 9, and the rigidity of the seat plate 72 and the reinforcing plate 9 is equal to or higher than that of the bottom cover 5. Reinforced.

  Finally, the bottom cover 5 to which the tripod seat 71 is attached is fixed to the camera body 3 with screws (not shown) or the like, thereby completing the assembly of the bottom of the camera.

  As described above, since the tripod seat 71 is fixed to the bottom cover 5, even if an external force is applied to the camera with the camera fixed to the tripod, it is possible to prevent the external force from being applied to the components in the camera body 3. Moreover, since the bottom cover 5 is sandwiched between the seat plate 72 and the reinforcing plate 9, the external force transmitted to the tripod seat 71 is distributed to the seat plate 72 and the reinforcing plate 9 and transmitted to the bottom cover 5. As a result, the bottom cover 5 is hardly damaged by an external force.
