Reference numeral 6 denotes a release button, which performs shooting by pressing the button during shooting. The digital camera 1 detects the pressing of the release button 6 and controls the driving of the image pickup device, the operation of the image processing circuit, the compression processing of the recording processing circuit, etc. (not shown), and records the photographed image on the memory card 12 or the like. I do. As can be seen from FIG. 1, in digital cameras, in particular, single-lens reflex cameras, emphasis is placed on holdability rather than portability, and it is important that the grip portion 5 protrudes greatly and has a three-dimensional shape with excellent holdability.

  2A and 2B show a state in which the card cover 10 of FIG. 1 is opened. 2A shows a state in which the memory card 12 is not stored, and FIG. 2B shows a state in which the memory card 12 is stored.

  2A and 2B, a recess 11 is formed on the side surface of the camera 1 with the card lid 10 opened. The outer surface of the card lid 10 has a shape corresponding to the outer shape of the grip portion 5 shown in FIG. 1, and the card lid 10 constitutes a part of the grip portion 5 of the camera 1 by covering the recess 11. It is like that. In the recess 11, a card slot 13 for storing the memory card 12 opens toward the inside of the camera 1. Reference numeral 14 denotes an eject button for removing the memory card 12. The photographer can perform the detachment operation of the memory card 12 with respect to the card slot 13 while the card cover 10 is open.

  Next, the opening / closing detection structure of the card cover 10 of this embodiment will be described with reference to FIG.

  First, the opening / closing operation | movement of the card cover 10 of this embodiment is demonstrated using Fig.3 (a)-FIG.3 (c). Fig.3 (a) is the figure which looked at FIG.2 (b) from the side surface. 3B and 3C are cross-sectional views taken along line AA in FIG. As will be described later, in FIG. 3B, the card cover 10 is in an intermediate state, and in FIG. 3C, the card cover 10 is in a closed state.

  3A to 3C, the rotation shaft 15 is provided along the Y direction at the Z plus side end of the recess 11. A mounting portion 16 is integrally formed at the end portion on the inner surface side of the card lid 10. A long hole-shaped guide hole 16a is formed in the attachment portion 16, and the rotating shaft 15 passes through the guide hole 16a. Therefore, the card cover 10 can move from the open state in which the card cover 10 is opened to the intermediate state (FIG. 3B) rotated about the rotation shaft 15. Further, the card cover 10 can be slid in the Z plus direction from the intermediate state so that the rotation shaft 15 extends along the guide hole 16a, and the card cover 10 is integrated with the grip portion 5 of the camera 1 (closed state). 3 (c)).

  An opening spring 17 is attached to the rotating shaft 15. The opening spring 17 is composed of a torsion coil spring. The coil portion is wound around the rotary shaft 15, one end is locked to the camera 1, and the other end is locked to the inner surface of the card lid 10. With this structure, the opening spring 17 urges the card lid 10 to rotate in the opening direction and urges it to maintain this open state.

  A click spring 18 is attached to the inner surface of the card lid 10. The click spring 18 is a leaf spring, and one side is fixed to the inner surface of the card lid 10 with a screw. The other side of the click spring 18 extends to the rotating shaft 15, and step portions 18 a and 18 b are formed at the tip portion. The step portion 18a is engaged with the rotary shaft 15 from the opened state of the card lid 10 to the intermediate state. When the card cover 10 slides from the intermediate state to the closed state, the stepped portion 18a is detached from the rotating shaft 15, and when the card lid 10 is closed, the stepped portion 18b engages with the rotating shaft 15. This engagement / disengagement provides a click feeling when the card lid 10 is slid.

  Further, a click spring cover 19 is attached to the inner surface of the card cover 10 so as to cover the click spring 18, and as will be described later, the card cover 10 is in contact with a part of the elastic member 24 in the closed state. And functions as a part of the drip-proof structure of the card lid 10.

  Further, the card lid 10 is formed with a projection 28 as a pressing portion for pressing an open / close detection switch 30 for detecting the opening / closing of the card lid 10 disposed in the slit 31 of the camera 1 as will be described later. Function.

  Next, the drip-proof structure of the card cover 10 of this embodiment will be described with reference to FIGS. 3 (b) to 3 (f). FIG.3 (d) is the figure which looked at Fig.2 (a) from the back surface. 3 (e) and 3 (f) are cross-sectional views taken along the line BB in FIG. 3 (a). 3E shows the card cover 10 in an intermediate state, and FIG. 3F shows the card cover 10 in a closed state.

  3B and 3C, a front side wall surface 20 and a rear side wall surface 21 are formed on the inner side surfaces on both sides in the Z direction of the recess 11. 3D to 3F, slopes 22 and 23 that are inclined so as to gradually become higher in the X minus direction along the sliding direction are formed on the inner side surfaces on both sides in the Y direction of the recess 11. Is formed. Here, the slopes 22 and 23 are parallel to each other. As can be seen from the figure, the grip portion 5 of the camera 1 has a three-dimensional shape with excellent holdability when held by the photographer. There, the card cover 10 is arranged so that the rotating shaft 15 side becomes thicker in the X minus direction. Therefore, it is possible to form the slopes 22 and 23 efficiently in space.

  Elastic members 24 and 25 are attached to the front side wall surface 20, the rear side wall surface 21, and the slopes 22 and 23 by sticking, welding, or the like as seal members, respectively. As these elastic members, foamed resins such as urethane foam, elastic rubber, and the like can be used.

  Here, as shown in FIG. 3D, the elastic member 25 attached to the rear side wall surface 21 and the slopes 22 and 23 has a U-shape, and the elastic members 25a, 25b and 25c are integrated. It has become. Further, as will be described later, attachment portions 25d and 25e are also provided outside the bent portion of the elastic member 25.

  Further, the end of the elastic member 24 and the end of the elastic member 25 are attached so as to be close to each other, and are arranged so as to surround the card slot 13.

  3B to 3F, when the card lid 10 is closed, as described above, the card lid 10 is first brought down from the upright state to the intermediate state. Then, the card cover 10 is slid in the Z plus direction to be in the closed state. At this time, after the elastic bodies 25 b and 25 c come into contact with the slopes 26 and 27 of the card lid 10, the elastic members 24 and 25 a attached to the front side wall surface 20 and the rear side wall surface 21 are pressed by the card lid 10. Further, the end portions of the elastic member 24 and the end portion of the residual member 25 are arranged close to each other, and when the card cover 10 is closed, the elastic member is pressed and spreads so that the elastic members are in close contact with each other. Here, the place where the elastic body 25c and the inclined surface 27 of the card lid 10 are in contact is the same as that shown in FIGS. Thereby, the drip-proof of the card cover 10 is securable.

  Here, the camera 1 is formed so that the slopes along the sliding direction of the card lid 10 are parallel to each other, and the elastic body 25 is attached to the slopes 22 and 23 of the camera 1. Thus, the card lid 10 can be smoothly slid. Accordingly, since the elastic body 25 is not rubbed and deteriorated by the sliding of the card lid 10, the drip-proof performance can be maintained.

  The elastic member 25 has a U-shape, and the elastic members 25a, 25b, and 25c are integrated and attached to the rear side wall surface 21 and the inclined surfaces 22 and 23 of the camera 1 so that the elastic body 25 is attached to the card cover. When force is applied by 10 slides, it becomes difficult to peel off. Furthermore, since the attachment part is provided also outside the bending part 25a of the elastic member 25, when the elastic member 25 is bent and attached by providing the attachment part also outside the bending part 25a of the elastic member 25, A sufficient mounting strength can be ensured with respect to the recovery force of the elastic member 25.

  Next, the opening / closing detection structure of the card cover 10 of the present embodiment will be described with reference to FIGS. 3 (g) to 3 (j). 3 (g) to 3 (j) are CC cross-sectional views in FIG. 2 (b).

  3 (g) to 3 (j), the card lid 10 has a protrusion 28, and an open / close detection disposed on the substrate 29 for detecting the opening / closing of the card lid 10 inside the camera 1. It functions as a pressing part for pressing the switch 30. A slit 31 is provided at a position between the card slot 13 and the elastic member 24, and an open / close detection switch 30 protrudes from the slit 31. When the card cover 10 slides in the Z plus direction, the open / close detection switch 30 is pushed in the Z plus direction by the protrusion 28 and is turned ON. As can be seen, the elastic members 25b and 25c are attached to the slopes 22 and 23, and the end surfaces of the elastic members 24 and 25 are arranged close to each other. A switch 30 can be arranged. Therefore, since the open / close detection switch 30 is provided at a position overlapping the position of the memory card 12 in the longitudinal direction of the memory card 12, the size of the card cover 10 can be reduced.

  When closing the card cover 10, as described above, the card cover 10 is first brought down from the standing state to the intermediate state. Then, the card cover 10 is slid in the Z plus direction to be in the closed state. At this time, since the protrusion 28 is provided so as to be positioned between the memory card 12 and the detection switch 30 in the intermediate state, the protrusion 28 is not in the memory even when the memory card 12 is not inserted deep into the card slot 13. There is no contact with the card 12.

  Thus, when the open / close detection switch 30 is pressed (that is, in the ON state), a control unit (not shown) incorporated in the camera 1 recognizes that the card lid 10 is closed, and enters the card slot 13. Access to the inserted memory card 12 becomes possible.

  When the card cover 10 is in the open state, the protrusion 28 does not reach the open / close switch 30, and the open / close detection switch 30 is in the OFF state. At this time, the control unit (not shown) recognizes that the card cover 10 is open and cannot access the memory card 12 inserted into the card slot 13.

  Here, a closing convex portion 32 is formed on the inner surface of the Z minus side end portion of the card lid 10. Further, a closing recess 33 is formed on the Z minus side of the recess 11 of the camera 1 so as to face the closing protrusion 32. The closing convex portion 32 and the closing concave portion 33 are engaged with each other, and the card lid 10 is closed. At this time, the closed concave portion 32 and the closed convex portion 33 are engaged to maintain the closed state.

  Further, as shown in FIG. 3 (j), when the projection 28 approaches the open / close detection switch 30 from a direction other than the sliding direction of the card lid 10, before the projection 28 contacts the open / close detection switch 30, the card lid 10 Therefore, the projection 28 does not destroy the open / close detection switch 30. Here, since the open / close detection switch 30 and the closing convex portion 32 and the closing concave portion 33 are provided at substantially the same height in the Y direction, even when the card lid 10 is inclined due to the closing convex portion 32 and the closing concave portion 33 coming into contact with each other. The open / close detection switch 30 can be protected.

  As described above, the card cover 10 is arranged in a three-dimensional shape having excellent holdability of the grip portion 5 of the camera 1 so that the rotation shaft 15 side is thick in the X minus direction with good space efficiency. When the card cover 10 is slid and closed, the elastic member 25 is gradually raised along the sliding direction in the camera 1 so as to reduce wear of the elastic member 25 attached to the inner side surfaces of the concave portion 11 on both sides in the Y direction. It attaches to the slopes 26 and 27 which became. And it attaches so that the edge part of the elastic member 25 and the edge part of the elastic member 24 may adjoin. Here, a space is created in the X minus direction in a range surrounded by the elastic members 24 and 25, and the opening / closing detection switch 30 of the card lid 10 can be disposed in the space on the rotating shaft 15 side.

  Therefore, since the opening / closing detection switch 30 of the memory card 12 and the card cover 10 is provided in the area surrounded by the elastic members 24 and 25, the drip-proof property can be improved. Furthermore, since the open / close detection switch 30 is provided at a position overlapping the position of the memory card 12 in the longitudinal direction of the memory card 12, the size of the card cover 10 can be reduced.

  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.
