As shown in FIG. 3, batteries 13a to 13d are housed in the lower portion of the camera 1, and the left end portion 1d of the lower portion is stored.
Ejected from (Fig. 2). FIG. 2 shows a state in which the battery case 12 is mounted, and when the battery case 12 is pulled out from the camera 1 to the left in the figure, the two are separated. Eight AA batteries are stored in the battery case 12. In Figure 3,
Only four on one side are shown. A tripod mounting screw 14 is fixed to the bottom surface 1e of the camera 1. Battery case 1
In order to be able to load and unload 2 in the left-right direction of FIG. 2, the batteries 13a and 13b in the lower row (and the batteries 13e and 13f in the lower row (not shown)) are separated by a tripod mounting screw 14. Are arranged.

FIG. 4 is a vertical sectional view taken along the line AA in FIG. The back surface 1c, the bottom surface 1e, the front surface 1f, and the inner partition wall 15 of the camera 1 form a battery storage portion in the lower portion of the camera 1. The right side portion 15a of the partition wall 15 has a battery housing portion and a back surface 1
A space is formed between c and the space for accommodating the second display panel 8 and the selection buttons 9, 10 and 11 is secured.

In the battery compartment, the batteries 13a, 13

13c, 13f, and 13g) are held by the holder portion 12 (FIG. 3) of the battery case 12. Since the tripod mounting screw 14 is provided on the bottom surface 1e, the battery 13a and the battery 13e in the lower row are arranged separately to avoid the tripod mounting screw 14. On the other hand, batteries 13 in the upper row
d and the battery 13h are arranged apart from each other by the required thickness of the holder portion 12a. Therefore, the battery 13e (and 13f (not shown)) in the lower row protrudes rearward (right side in the drawing) from the battery 13h (and 13g (not shown)) in the upper row. As a result, a space is formed between the right side portion 15a of the partition wall 15 and the back surface 1c of the camera 1.

Further, the batteries 13a and 13d on the front side (left side in FIG. 4) are located substantially at the upper and lower positions, while the batteries 13e and 13h on the rear side (right side in FIG. 4) are located at the oblique positions. Comparing this with the battery arrangement of the conventional example (see FIG. 7), in the conventional case, the batteries 103c and 103g are evenly projected back and forth with the tripod mounting screw 14 interposed therebetween.
In this embodiment, only the rear side (right side in FIG. 4) is projected. As a result, a larger space is formed between the right side portion 15a of the partition wall 15 and the back surface 1c of the camera 1. Also,
It is also possible to improve the fact that the front protrusion hits the hand during lens operation and deteriorates operability.

A display LCD 16 of the second display panel and operation members 9 to 11 described later are housed in a space formed between the right side portion 15a of the partition wall 15 and the back surface 1c of the camera 1. The display LCD 16 is connected to the control circuit board 18 via the FPC 17, and is fixed to the back surface 1c by the board 19. A window portion 1g is provided on the back surface 1c, and the window member 20 made of acrylic resin or the like is used.
It is inset.

FIG. 5 is a cross-sectional view taken along the line BB in FIG. In the window member 20, only the display portion 20a facing the display LCD 16 is transparent, and the other portions are opaque. The selection buttons 9, 10, and 11 are provided on the operation unit 20b.
Is provided with a hole. Select buttons 9, 10,
And 11 are parts of the integrated rubber 21, and the conductive rubbers 9a, 10a, and 11a attached to them, respectively,
A switching operation can be performed by contacting a conductive pattern (not shown) on the facing FPC 17. The substrate 19 is
The selection buttons 9, 10, and 11 also extend to the back surface of the selection buttons, and have a structure for receiving a pressing operation. The operation portion 20b of the window member 20 is one step below the display portion 20a, and the surfaces of the selection buttons 9, 10 and 11 are slightly lower than the display portion 20a.

According to the embodiment described above, among the batteries arranged in the upper and lower two layers, the battery in the lower layer projects rearward to avoid the tripod mounting screw on the bottom of the camera, and the space between the rear surface of the camera and the rear surface of the camera. By providing the LCD display panel and the operation member related thereto by utilizing the fact that it is possible, it is possible to cope with the increase in the display content required according to the increase in the function without enlarging the display portion on the upper surface of the camera. Therefore, it is possible to reduce the size of the camera with increased display contents and operation members.

Moreover, since the rear display panel can be made substantially flush with the rear surface of the entire camera, the acrylic window does not project as compared with the case where the display panel is simply provided separately on the rear surface, so that it is not affected by external impact. It's advantageous, and it doesn't get in the way when you hold the camera. Furthermore, since the operation unit adjacent to the display unit is configured to be one step lower than the display unit, the operation button does not protrude from the back surface, and erroneous operation can be avoided.

Further, since the upper and lower widths of the display portion are limited because the upper and lower layers of the battery are used, the longitudinal direction is almost equal to that of the battery 2.
Since the length of the book can be utilized, a sufficient display area can be obtained.

Although the present embodiment is an electric camera in which the power source storage unit is integrated with the main body, it goes without saying that the present invention can also be applied to a camera in which a separate power source storage unit is attached to the lower side of the camera. Yes.
