  The lid body 7 is formed of a molding material or the like, and a plate 8 formed of a stainless steel plate or the like is disposed inside the lid body 7 relative to the lid body 7 between the closed position and the opened position of the lid body 7. It is slidably mounted in the direction. The plate 8 is attached to the lid body 7 by passing a dowel (slide portion) 7 a provided inside the lid body 7 through a long hole portion (guide portion) 8 a provided in the plate 8.

  Inside the lid body 7, guide ribs (slide parts) 7b, 7c extend along the X direction so as to sandwich the dowel 7a. The guide ribs 7b, 7c are bent parts (guides) provided on the plate 8. Part) 8b, 8c with a predetermined gap. As a result, the plate 8 can be slid relative to the lid body 7 in the X direction along the guide ribs 7b and 7c within the movable range of the dowel 7a penetrated through the long hole portion 8a.

  The lock lever 9 is disposed on a sliding surface 7d provided on the inner side of the lid main body 7, the operation portion 9a projects outward from the hole 7e of the lid main body 7, and the hook portion 9b engages with the engagement portion 8d of the plate 8. In combination, the sliding movement of the plate 8 in the X direction is restricted. Further, the lock lever 9 is pushed by the urging spring 10 so that the state in which the hook portion 9b is engaged with the engaging portion 8d of the plate 8 is maintained. When the engagement between the hook portion 9b of the lock lever 9 and the engagement portion 8d of the plate 8 is released, the lid main body 7 is moved from the closed position to the X (−) direction by the slide spring (first urging means) 11. It is urged to slide to the disengagement position.

  Here, in the present embodiment, as shown in FIG. 5, convex portions 7k projecting outward in the width direction are provided at the end portions on the X (+) side of the guide ribs 7b and 7c. As shown in FIGS. 4 and 5, the dimension between the outer surfaces of the guide ribs 7b and 7c at the portion where the convex portion 7k is provided is L1 ', and the guide rib at the portion where the convex portion 7k is not provided. The dimension between the outer surfaces of 7b and 7c is L1.

  Here, if the dimension between the outer surfaces of the bent portions 8b and 8c of the plate 8 is L2, the guide ribs 7b and 7c and the bent portions 8b and 8c until the lid body 7 is slid from the closed position to the disengaged position. The total gap in the Z direction is L2−L1 = ΔL12. Here, the Z direction is the rotational axis direction of the plate 8. On the other hand, the sum of the gaps in the Z direction between the guide ribs 7b and 7c and the bent portions 8b and 8c at the disengagement position of the lid body 7 is L2−L1 ′ = ΔL12 ′ (<ΔL12), which is smaller than ΔL12.

As for the width dimension of the long hole portion 8a of the plate 8, as shown in FIGS. 4 and 5, a portion L3 ′ narrower than L3 is provided on the X (−) side of the portion L3. Here, if the diameter of the dowel 7a of the lid 7 is L4, the total gap in the Z direction between the slot 8a and the dowel 7a until the lid body 7 is slid from the closed position to the disengaged position is L3−L4 = ΔL34. On the other hand, the sum of the gaps in the Z direction between the long hole portion 8a and the dowel 7a at the disengagement position of the lid body 7 is L3′−L4 = ΔL34 ′ (<ΔL34), which is smaller than ΔL34 .

  Returning to FIG. 3, the pressing plate 12 is formed of a molding material or the like, the screw hole 12 a is aligned with the dowel 7 a of the lid body 7, and the claw portion 12 b is hooked on the hook portion 7 g of the lid body 7. 7 is attached. Further, the pressing plate 12 is provided with an erroneous contact prevention rib 12c.

  When the batteries 4 and 5 such as AA batteries are stored in the storage unit 3 with the positive and negative electrodes being reversed, the erroneous contact prevention rib 12c damages the electronic circuit of the camera body 1 in the reverse direction. This is to prevent this.

  That is, as shown in FIG. 6, if the batteries 4 and 5 are stored in the storage unit 3 with the positive and negative directions being correct, the positive electrode 4a protrudes from the end face of the electrode 4 as shown in FIG. The positive electrode 4a is in contact with the terminal 13c of the electrode plate 13 and becomes conductive.

  FIG. 10 shows a partial cross-sectional view of the storage unit 3 in a state where the batteries 4 and 5 are stored in the storage unit 3 with the positive and negative electrodes oriented correctly. As shown in FIG. 10, at the bottom of the storage portion 3, there are a spring terminal 15 that contacts the negative electrode 4b of the battery 4 with an appropriate contact pressure, and a spring terminal 16 that contacts the positive electrode 5a of the battery 5 with an appropriate contact pressure. Is provided.

  On the other hand, when the batteries 4 and 5 are stored in the storage unit 3 with the positive and negative directions reversed as shown in FIG. 8, the end face of the battery 4 becomes a negative electrode 4b that does not protrude as shown in FIG. Contact with the terminal 13c of the electrode plate 13 is hindered by the erroneous contact prevention rib 12c. Thereby, when the batteries 4 and 5 are stored in the storage unit 3 with the directions of the positive and negative electrodes reversed, current is prevented from flowing in the reverse direction.

  The electrode plate 13 is formed of a conductive leaf spring material, the screw hole 13a is aligned with the screw hole 7f provided in the dowel 7a of the lid body 7, and the claw portion 13b is hung on the hook portion 7h of the lid body 7. Attached to the lid body 7. Then, the screw 102 inserted from the screw hole 13a of the electrode plate 13 is screwed into the screw hole 7f of the dowel 7a of the lid body 7 and tightened, whereby the lid 102 is assembled.

  Next, a procedure for attaching the lid 2 to the camera body 1 will be described with reference to FIG.

  First, as shown in FIG. 11, the hinge portions 8e and 8f of the plate 8 are inserted between the bearing portions 3a and 3b of the storage portion 3, and a torsion spring (second biasing means) is interposed between the hinge portions 8e and 8f. 17 is attached. Next, the shaft 8 is inserted into the bearing portions 3 a and 3 b, the hinge portions 8 e and 8 f, and the torsion spring 17, so that the plate 8 is rotatably attached to the camera body 1. Therefore, the lid 2 is rotatably attached to the camera body 1. In such an attachment state, both ends of the shaft 18 are supported by the bearing portions 3a and 3b, and the arm 17a of the torsion spring 17 biases the plate 8 from the closed position of the lid body 7 to the open position.

  The lid body 7 is provided with claw portions 7i, 7j, and the storage portion 3 is a hook for engaging the claw portions 7i, 7j at the closed position of the lid 2 to maintain the closed state of the lid 2. Portions 3c and 3d are provided. The housing 3 is cut out in a shape corresponding to the lid 2 so that the outer shape of the camera body 1 can be formed with the lid 2 closed. Further, as shown in FIG. 11, a detection switch 19 is provided at the opening edge of the storage portion 3. The detection switch 19 is for detecting whether or not the lock lever 9 is in the closed position of the lid 2 with respect to the plate 8. If the lock lever 9 is in the closed position of the lid 2, the detection switch 19 is pushed by the protrusion 9 c of the lock lever 9 and a detection signal is output to the control circuit of the camera body 1.

  Here, with reference to FIG. 12, in this embodiment, the width between the outer surfaces of the hinge portions 8e and 8f is set to a portion L5 and a portion L5 ′ wider than L5. In addition, as for the width between the inner surfaces of the bearing portions 3a and 3b, a portion L6 and a portion L6 ′ narrower than L6 are set. The total gap in the Z direction between the hinge portions 8e, 8f and the bearing portions 3a, 3b is set to L6-L5 = ΔL56 when the lid 2 is closed, and L6 is smaller than ΔL56 when the lid 2 is opened. '-L5' = ΔL56 '.

  Here, when performing normal shooting with a digital camera, etc., as described with reference to FIG. 3, the hook portion 9b of the lock lever 9 is pushed by the biasing spring 10 to engage with the engaging portion 8d of the plate 8. Then, the state where the lid 2 is closed is maintained. Thereby, it is possible to prevent the lid 2 from being inadvertently opened or the accessories from popping out from the storage unit 3. If the lid 2 is in the closed position, the detection switch 19 is pushed by the protrusion 9c of the lock lever 9, and the detection signal is output to the control circuit of the camera body 1, so that the digital camera operates normally. Can do.

  Next, when opening the lid 2 and taking out the batteries 4 and 5 and the memory card 6 from the storage portion 3, referring to FIG. 1, first, the operation portion 9a of the lock lever 9 is slid in the Z (+) direction. . Then, the protrusion 9c of the lock lever 9 moves away from the detection switch 19, and it is detected by the control circuit that the lid 2 has been opened, and the control circuit immediately stops the operation of the digital camera.

  Further, since the engagement between the hook portion 9b of the lock lever 9 and the engagement portion 8d of the plate 8 is released, the lid body 7 is disengaged from the closed position with respect to the plate 8 by the biasing force of the slide spring 11. Slide to position.

  Here, as described in FIGS. 4 and 5, the total gap in the Z direction between the guide ribs 7b, 7c and the bent portions 8b, 8c until the lid body 7 slides from the closed position to the disengaged position. Is L2−L1 = ΔL12. The total gap in the Z direction between the guide ribs 7b and 7c and the bent portions 8b and 8c at the disengagement position of the lid body 7 is L2−L1 ′ = ΔL12 ′ (<ΔL12), which is smaller than ΔL12.

The total gap in the Z direction between the long hole portion 8a and the dowel 7a until the lid body 7 slides from the closed position to the disengaged position is L3-L4 = ΔL34. The total gap in the Z direction between the long hole portion 8a and the dowel 7a at the disengagement position of the lid main body 7 is L3′−L4 = ΔL34 ′ (<ΔL34), which is smaller than ΔL34 .

  Therefore, until the lid body 7 is slid from the closed position to the disengaged position, the gap in the Z direction between the guide ribs 7b and 7c and the bent portions 8b and 8c and the Z direction between the long hole portion 8a and the dowel 7a are in the Z direction. The gap becomes larger. Thereby, the lid body 7 can be smoothly slid toward the disengagement position.

  In the disengagement position of the lid body 7, the gap in the Z direction between the guide ribs 7b and 7c and the bent portions 8b and 8c and the gap in the Z direction between the elongated hole portion 8a and the dowel 7a are reduced. As a result, the lid body 7 is less likely to interfere with the camera body 1. Furthermore, since the position of the lid body 7 is maintained by the urging force of the slide spring 11, it is easy to maintain a state in which the lid body 7 has less shakiness.

  When the hand is released from the lid body 2 in this state, the lid 2 automatically rotates in the opening direction due to the torsion spring 17 urging the rotational movement of the plate 8 from the closed position to the open position, and the torsion spring 17 The open state of the lid 2 is maintained by the biasing force of the spring 17.

  In addition, as described with reference to FIG. 12, the total gap in the Z direction between the hinge portions 8 e and 8 f and the bearing portions 3 a and 3 b is set to L6−L5 = ΔL56 at the closed position of the lid 2. In the open position, L6′−L5 ′ = ΔL56 ′ smaller than ΔL56 is set.

  Therefore, from the closing position of the lid 2 to the middle of the opening operation, the total gap in the Z direction between the hinge portions 8e and 8f and the bearing portions 3a and 3b becomes large, so that the lid 2 can rotate smoothly. .

  In addition, since the total gap in the Z direction between the hinge portions 8e and 8f and the bearing portions 3a and 3b becomes small at the open position of the lid 2, the backlash of the lid 2 is reduced and the lid 2 is attached to the camera body 1. It becomes difficult to collide. Furthermore, since the open state of the lid 2 is maintained by the urging force of the torsion spring 17, it is easy to maintain a state in which the lid 2 is less rattling.

  Next, when the batteries 4 and 5 and the memory card 6 are stored in the storage unit 3, as shown in FIG. 10, the negative electrode 4b of the battery 4 and the positive electrode 5a of the battery 5 have an appropriate contact pressure and the spring terminal 15 and the spring terminal 16 respectively. To touch. When the lid 2 is closed in this state, as shown in FIG. 7, the positive electrode 4 a of the battery 4 contacts the terminal 13 c and is energized, and power is supplied to the camera body 1 through the spring terminals 15 and 16.

  Further, when the lid 2 is to be closed while the batteries 4 and 5 are erroneously inserted into the storage portion 3, the attachment gap amount in the Z direction of the lid 2 is small and is not easily displaced in the Z direction, as shown in FIG. In the process of closing the lid 2, the erroneous contact prevention rib 12 c correctly contacts the negative electrode 4 b on the end face of the battery 4. Therefore, a gap is secured between the terminal 13c of the electrode plate 13 and the negative electrode 4b of the battery 4, and damage to the control circuit due to the generation of reverse current can be prevented.

When the lid 2 is rotated and closed in this state and the lid body 7 is further slid in the X (+) direction, the hook portion 9b of the lock lever 9 is pushed by the biasing spring 10 and the engaging portion of the plate 8 is engaged. 8d is engaged, and the lid 2 is kept closed. At the closed position of the lid 2, the gaps ΔL 12, ΔL 34, and Δ L 56 are provided in the Z direction as in the prior art. It can be moved so as to be approximately coincident.
