  FIG. 4 is a perspective view showing an internal structure of the camera body 11 in a state in which the storage unit cover 20 attached to the camera body 11 is removed. The opening / closing rotary shafts 16 a and 16 b of the card lid 16 are rotatably attached to the card holder 19. The card lid reversal leaf spring 21 is an elastic member disposed on the top of the card lid 16. The card cover reversal leaf spring 21 is fixed to the camera body 11 by a leaf spring fixing screw 22. The card lid reversing plate spring 21 is in contact with the cam-shaped portion 16c for opening and closing the card lid 16 and biases the cam-shaped portion 16c when the card lid 16 is in the open position and the closed position. It has become. As a result, the card cover 16 is maintained in a stable posture regardless of whether the card cover 16 is in the open position or the closed position.

  In the present embodiment, the angle at which the card cover 16 opens until the card cover 16 moves from the closed position shown in FIG. 1 to the open position shown in FIG. 2 is set to about 65 degrees. This opening angle is sufficient to take out the memory card 51 inserted into the card slot 18.

  When the card lid 16 is in the closed position shown in FIG. 1, the card lid 16 is substantially flush with the storage portion cover 20 and does not protrude outward. Further, the card lid 16 is designed so that the tip end portion of the card lid 16 is located at substantially the same height as the outer appearance surface of the storage portion cover 20 even when the card lid 16 is in the open position shown in FIG. Therefore, even if the display unit 15 is rotated in the closing direction when the card lid 16 is in the open position, the card lid 16 does not contact the liquid crystal panel screen 30, and the liquid crystal panel screen 30 is not damaged.

  FIG. 5 is a perspective view showing the internal structure of the camera body 11 with the card cover 16 and the card holder 19 removed from the state shown in FIG. The card board 24 on which the card slot 18 is mounted is connected to the main board 23 by a flexible board (not shown), and data is exchanged (transmitted / received) between these boards.

  FIG. 6 is a side view of the camera body 11 when the display unit 15 is closed with the card lid 16 open. 7 is a cross-sectional view taken along the line AA shown in FIG. The photographing lens barrel 25 shown in FIG. 7 is an inner focus type lens barrel having a four-group configuration used in a general video camera, and captures reflected light from the subject and captures the subject image on the light receiving surface of the image sensor 26. Is imaged. In the photographic lens barrel 25, the distance between the front lens closest to the subject surface and the image sensor 26 is fixed, and the variator lens and the focus lens inside are movable to perform zooming and focusing. ing.

  The image sensor 26 is mounted on the sensor substrate 27. The sensor board 27 is mounted with an A / D conversion element for converting an analog electric signal output by photoelectric conversion in the image pickup element 26 into a digital signal and a peripheral circuit, and is connected to the main board 23 by a BtoB connection (not shown). Has been. Image data (video data) of an image (video) obtained by the imaging element 26 is stored in a memory card 51 accommodated in the card slot 18. A sensor heat radiating plate 28 is screwed to the sensor substrate 27, and the sensor heat radiating plate 28 can efficiently radiate heat from the A / D conversion element mounted on the sensor substrate 27.

  As shown in FIG. 7, the card substrate 24 is disposed in the camera body 11 in a state of being inclined with respect to the optical axis or the imaging surface of the imaging element 26. That is, the card substrate 24 is arranged in the camera body 11 so that the substrate surface intersects the optical axis of the photographing lens barrel 25 or the imaging surface of the imaging element 26 at a predetermined angle. In the present embodiment, the intersection angle between the substrate surface of the card substrate 24 and the optical axis of the photographic lens barrel 25 is about 65 degrees, that is, the intersection angle between the substrate surface of the card substrate 24 and the imaging surface of the image sensor 26 is about 25. It is a degree. As a result, the card slot 18 also intersects the optical axis of the photographic lens barrel 25 at an angle of about 65 degrees (the intersection angle with the imaging surface of the image sensor 26 is about 25 degrees). With the installation angle of about 65 degrees (or 25 degrees), the projected area of the card substrate 24 when viewed from the optical axis direction of the optical axis 29 of the photographic lens barrel 25 is approximately within the projected area of the photographic lens barrel 25. Has been determined to be. By arranging the card substrate 24 obliquely with respect to the optical axis 29 in this way, the width of the camera body 11 in the left-right direction is not increased beyond the element determined by the width of the photographing lens barrel 25, A small casing (camera body 11) can be realized.

  Further, by disposing the card substrate 24 so as to be inclined with respect to the optical axis 29, the memory card can be taken out even if the opening / closing angle of the card lid 16 is set to a small angle. Therefore, the length of the card lid 16 in the opening / closing direction can be shortened, and the storage space when the card lid 16 is in the open position can be reduced. Further, when the card cover 16 is in the open position, the card cover 16 passes through one surface of the card slot 18, one surface of the storage unit cover 20 (the exterior surface of the camera body 11), and the back end of the card slot 18. And stored in a space 40 surrounded by three planes that are orthogonal to the optical axis 29 (a plane parallel to the imaging surface of the imaging device 26). Therefore, downsizing of the camera body 11 is not hindered.

  FIG. 8 is a perspective view showing the peripheral structure of the card lid 16, and shows only the storage section cover 20, the card lid 16, the card holder 19, and the card lid reversal leaf spring 21. The card holder 19 is provided with stopper portions 19a and 19b and rib portions 19c and 19d in the vicinity of a portion where the opening / closing rotary shafts 16a and 16b of the card lid 16 are attached. The role of the stopper portions 19a and 19b and the rib portions 19c and 19d will be described with reference to FIG.

  FIG. 9A is a sectional view through the stopper portion 19a of FIG. FIG. 9B is a cross-sectional view through the rib portion 19c of FIG. In the present embodiment, since the card lid 16 is housed inside the camera body 11, the card lid 16 and the card slot 18 approach when the card lid 16 is in the open position. At this time, as shown in FIG. 9A, force in the direction of arrow B (force in a direction perpendicular to the exterior surface of the camera body 11) is likely to be applied to the card lid 16 in the open position.

  Here, the opening / closing rotation shaft 16 a (and 16 b) of the card cover 16 is disposed above and below the card cover 16. When a force in the direction of arrow B is applied to the card lid 16, the card lid 16 is easily bent inward, and the central portion of the card lid 16 is easily moved in the direction of arrow B.

  However, in the present embodiment, when a force in the direction of arrow B is applied to the card lid 16, the card lid 16 abuts against the stopper portions 19a and 19b. That is, the card cover 16 has a structure that cannot be rotated more than a certain angle by the stopper portions 19a and 19b provided at positions where the force in the direction orthogonal to the exterior surface of the camera body 11 is received. Accordingly, the stopper is surely effective in a direction (parallel to the arrow B direction) perpendicular to the storage surface in which the card cover 16 is stored, so that the opening / closing angle (about 65 degrees) of the card cover 16 can be maintained.

  Further, as shown in FIG. 9B, in the present embodiment, the rib portion 19c (and 19d) is provided at a position where the clearance is slightly provided with the card lid 16. Therefore, even if a rotational torque in the same direction as the rotational direction when the card cover 16 is moved from the closed position to the open position is further applied to the card cover 16 in the open position, the tip end portion 16f of the card cover 16 is The card lid 16 is prevented from rotating by contacting the rib portion 19c. That is, the rib portions 19c and 19d function as a preliminary stopper portion that assists the stopper portions 19a and 19b. Thus, by providing the card holder 19 with the stopper portions 19a and 19b and the rib portions 19c and 19d, the card lid 16 does not interfere with the card slot 18 even if a strong external force acts on the card lid 16 in the open position. . Therefore, it is possible to prevent the occurrence of problems such as deformation of the card slot 18.
