A surface 1912 composed of a short side 191 and a middle side 192 is orthogonal to the long side 193 and includes a terminal portion 195 for supplying power. On the surface 1923a composed of the middle side 192 and the long side 193, a logo (not shown) and a cautionary note are written.

  Next, the configuration of the main chassis 15 will be described with reference to FIGS. FIG. 1a is a side view of the camera 1 in the present embodiment, FIG. 1b is a cross-sectional view taken along line AA in FIG. 1a, and FIG. 1c is an enlarged view of B in FIG. FIG. 5 is a diagram showing the overall structure of the main chassis.

  The main chassis 15 has a metal sheet metal 150 inserted in a resin portion, and has a battery box 151 for storing a battery. In the present embodiment, the main chassis 15 and the battery box 151 have an integral structure, but the battery box 151 may be formed of separate parts. The battery box 151 has substantially the same external shape as the battery 19, and has a battery storage unit 152 for storing the battery 19. As shown in FIG. 1c, when the battery is inserted, the battery storage portion 152 has the surface 1923a of the battery 19 facing the palm portion 311 side of the grip portion 31 and the surface 1923b of the battery 19 facing the finger engagement portion 312 side. Placed in.

  The long side 193a is arranged on the camera center side and the subject side, and the long side 193b is arranged on the camera center side and the photographer side. Furthermore, the triangular space 80 is created between the front cover 30, the back cover 50, and the surface 1923a by arranging the long side 193a on the outer side of the camera 1 with respect to the optical axis so as to be inclined with respect to the optical axis. It is possible to dispose an exterior fixing screw seat 153 for fixing the exterior to the triangular space 80. The exterior fixing screw seat 153 is for fixing the front cover unit 30 and the back cover unit 50. However, in addition to the exterior member, a sheet metal or the like may be fastened together if necessary.

  When the battery 19 is arranged so as to reduce the angle from the optical axis, the triangular space 80 is also reduced, and in order to secure the self-tap pilot hole depth of the screw seat 153, it is necessary to penetrate to the battery storage portion 152. Decreases. Therefore, it is preferable to arrange the battery 19 so as to have an angle from the optical axis in a range in which the self-tapping pilot hole of the exterior fixing screw seat 153 does not penetrate. In this embodiment, the screw seat 152 for fixing the exterior is arranged, but there is no limitation on the fixing configuration such as a hook for fixing the exterior or a press-fitting mechanism, but the camera can be fixed firmly with a screw. 1 can be increased in rigidity.

  As described above, by providing the screw seat 153 in the triangular space 80, the exterior member can be fixed without increasing the lateral width of the camera 1. Further, a battery lock portion 155 for holding the battery 19 is provided on the subject side of the battery box 151, and the battery lock portion 155 is formed of an elastic member.

  Next, a method for attaching the battery 19 to the camera 1 and a method for removing the battery will be described with reference to FIGS. FIG. 6A is a perspective view when a battery is attached to the camera 1 in the present embodiment, and FIG. 6B is a perspective view in which only the chassis and the battery are displayed from FIG. 6A. 7a is a side view when only the camera 1 chassis and the battery in the present embodiment are displayed and the battery is mounted, FIG. 7b is a view when the battery lock part and the battery come into contact with FIG. 7a, and FIG. It is the figure which the installation of the battery was completed from the state of 7b. FIG. 8 is a view of the camera 1 according to the present embodiment as viewed from the bottom of the camera with the battery cover opened.

  When the user attaches the battery 19 to the camera 1, the battery 19 is inserted into the battery box 151 of the camera 1 in the direction of the long side 193 (direction of arrow A) from the surface 1912 a side. When the battery 19 comes into contact with the slope of the battery lock 155, the battery lock 155 is elastically deformed in the direction of arrow B, slides on the surface 1913, and is locked by the surface 1912b. When the battery 19 is removed, the lock is released by deforming the battery lock portion 155 in the optical axis direction as shown in FIG. The battery 19 is disposed at a position tilted with respect to the optical axis, but the user's release operation direction (the direction of the arrow C) may be slid in the optical axis direction without matching the tilt direction.

  Reference numeral 1551 denotes the tip of the battery lock unit 155. By aligning the tip of the battery lock unit 155 with the inclination of the battery, the sense of unity between the inclination of the battery 19 and the semi-appearance of the battery lock unit tip 1551 when the battery cover 70 is opened. Therefore, it is preferable.

  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.
