[1-2. Pop-up operation and storage operation of flash light emitting unit]
The flash light emitting unit 100 which is a built-in flash according to the present embodiment is a type in which the user manually pops up the flash light emitting unit 100 when the flash light emitting unit 100 is used, and is manually stored by the user when not in use. When the user manually slides the operation knob 124 shown in FIG. 1 in the forward direction, the flash light emitting unit 100 protrudes upward. Conversely, when the user manually pushes down the flashing light emitting unit 100 in the protruding state in FIG. 2, the flashing light emitting unit 100 moves to the storage position and enters the storage state. The stored state is held until the operation knob 124 is slid next time.

  3 and 4 are cross-sectional views for explaining the mechanism of the pop-up operation and the storage operation of the flash light emitting unit. FIG. 3 shows a protruding state of the flash light emitting unit, and FIG. 4 shows a stored state.

  5 and 6 are exploded perspective views for explaining the mechanism of the pop-up operation and the storage operation of the flash light emitting unit. FIG. 5 shows a structure including a link for a pop-up operation and a spring as a power source thereof. FIG. 6 shows the structure of a locking lever that holds and releases the flashlight.

  In FIGS. 3 and 4, the link 114 is rotatably supported by an axis B 116 with respect to the base 118. The spring B122 is installed between the base 118 and the link 114, and applies a torque for rotating the link 114 counterclockwise to the base 118. The light emitting unit case B111 is pivotally supported on the link 114 by an axis A115. The spring A121 is installed between the link 114 and the light emitting unit case B111, and applies a torque for rotating the light emitting unit case B111 in the clockwise direction to the link 114.

  In FIG. 4, the light emitting unit case B <b> 111 has a fixing claw 113. The fixing claw 113 of the light emitting unit case B111 is engaged with a locking claw 117 described later provided on the locking lever 119. This engagement resists the rotational torque generated by the spring A121 and the spring B122, thereby holding the flash light emitting unit 100 in the housed state.

  The pop-up operation of the flash light emitting unit 100 will be described below. When the locking claw 117 moves in the forward direction of the digital camera 10 by the operation of an operation knob 124 described later provided on the locking lever 119, the engagement between the fixed claw 113 and the locking claw 117 described above is released. When the engagement is released, the link 114 rotates counterclockwise by the torque of the spring B122. Simultaneously with the rotation of the link 114, the light emitting unit case B111 is rotated clockwise by the torque of the spring A121. Each of the link 114 and the light emitting unit case B111 rotates until it comes into contact with the stopper, stops at the position shown in FIG. 3, and enters a protruding state. With the above operation, the pop-up operation of the flash light emitting unit 100 is performed.

  The operation of the operation knob 124 and the locking claw 117 will be described below. In FIG. 6, the operation knob 124 is engaged and fixed to the locking lever 119. The locking lever 119 is held between the base 118 and the locking lever plate 123 so as to be linearly movable in the lever operating direction shown in FIG. The locking lever spring 120 is a compression coil spring and is installed between the locking lever 119 and the base 118. The locking lever spring 120 biases the locking lever 119 in the rear direction of the digital camera 10. When an operating force is input to the operation knob 124, the locking lever 119 moves forward against the force of the locking lever spring 120. At that time, the locking claw 117 provided integrally with the locking lever 119 also moves in the forward direction, and the movement disengages the locking claw 117 and the fixed claw 113 shown in FIG. Pop-up action occurs.

[1-3. Packing configuration]
FIG. 7 shows the shape of the flash light emitting portion and the surrounding camera body in the protruding state of the flash light emitting portion.

  As shown in FIG. 7, a packing 101 is attached around the light emitting panel, which will be described later, of the flash light emitting unit 100 so as to surround the light emitting panel. The packing 101 is an example of an elastically deformable member. Specifically, the material of the packing 101 is silicone rubber, and the packing 101 can be relatively elastically deformed. The shape of the packing 101 is annular. A concave portion 105 that opens upward from the digital camera 10 is formed in the upper portion of the body case 210 on the camera body side. The recess 105 houses the flash light emitting unit 100. A rib 211 is formed on the main body case 210 over the entire periphery of the opening of the recess 105. The rib 211 in the present embodiment is a protrusion protruding upward.

  Next, the packing attachment state will be described with reference to FIG. FIG. 8 is an exploded perspective view of the flash light emitting unit. The light-emitting panel includes a Fresnel lens 103, a light-emitting unit 102, a circuit board 104, a packing 101, a light-emitting unit case A110, a screw 112, and a light-emitting unit case B111.

  As shown in FIG. 8, the light emitting unit case B111 holds the Fresnel lens 103, the light emitting unit 102, the circuit board 104, and the packing 101 while positioning them. The light emitting unit case A110 is fastened to the light emitting unit case B111 with two screws 112. The Fresnel lens 103, the light emitting unit 102, and the circuit board 104 are accommodated in a space surrounded by the light emitting unit case A110 and the light emitting unit case B111. The packing 101 is sandwiched and fixed between the light emitting unit case A110 and the light emitting unit case B111.

  When the user removes the packing 101, the light emitting unit case A110 is removed by removing the two screws 112, and the packing 101 is removed from the light emitting unit case B111.

  FIG. 10 is a cross-sectional view showing the deformation of the packing due to contact with the ribs at the cross-sectional position when cut in the vertical direction (direction perpendicular to the paper surface of FIG. 9) along the line 10-10 shown in FIG. is there. FIG. 10A shows a state before the rib 211 and the packing 101 are in contact with each other. FIG. 10B shows a state where the rib 211 and the packing 101 are in contact with each other. That is, FIG. 10B shows the storage state of the flash light emitting unit 100.

  In a non-contact state in which the rib 211 and the packing 101 are not in contact, the shape of the cross section of the packing 101 (the cross section in a plane parallel to the vertical direction of the digital camera 10) is vertical as shown in FIG. It is a substantially L-shape composed of a side in the direction and a side in the horizontal direction. Let the upper end of the edge | side of a vertical direction be the packing base 101A. The horizontal side is a side extending outward from the lower end of the vertical side. In the contact state in which the packing 101 and the rib 211 are in contact, the shape of the cross section of the packing 101 is a shape that is deformed so that the side in the horizontal direction jumps up as shown in FIG. In this manner, when the flash light emitting unit 100 is housed, the packing 101 is pressure-deformed between the flash light emitting unit 100 and the camera main body 200, whereby a drip-proof seal is provided between the camera main body 200 and the flash light emitting unit 100. . The drip-proof seal is a sealed state that suppresses the entry of water. This drip-proof seal makes the digital camera 10 drip-proof.

  That is, due to the repulsive force of the packing 101 according to the deformation of the packing 101, the packing 101 and the rib 211 are in close contact with each other, and water enters the camera body 200 from the outside of the digital camera 10 (path A in FIG. 11). Is blocked.

  Further, the packing base portion 101A is sandwiched between both the light emitting portion case A110 and the light emitting portion case B111 over the entire circumference, and is in contact with both of them. The contact portion of the packing base 101A with the light emitting unit case A110 and the light emitting unit case B111 prevents water from entering the flash light emitting unit 100 from the outside of the digital camera 10 (path B in FIG. 11).

  As described above, in the digital camera 10 of the present embodiment, both the path B from the outside of the digital camera 10 to the inside of the flash light emitting unit 100 and the path A from the outside of the digital camera 10 to the inside of the camera body 200 are prevented. Drip-sealed and drip-proof.

(Modification of Embodiment 1)
FIG. 12 is a cross-sectional view showing a modification of the first embodiment. 12 is the same position as the 10-10 cross section shown in FIG. FIG. 13 is a cross-sectional view showing a packing mounting configuration.

  In the modification, the packing 101 is not attached to the flash light emitting unit 100 as described in the first embodiment, but is attached to the camera body 200 as shown in FIG. As shown in FIG. 12, the fixed plate 212 is an attachment member that can be detached without separating and disassembling the flash light emitting unit 100 from the camera body 200. The shape of the fixing plate 212 is an annular shape similar to the shape of the opening of the recess 105 of the main body case 210. The cross-sectional shape of the fixed plate 212 on the plane parallel to the vertical direction of the digital camera 10 is substantially L-shaped. As shown in FIG. 12, the vertical side of the fixing plate 212 faces the inner side surface in the vicinity of the opening of the recess 105. The lateral side of the fixed plate 212 is disposed on the outer periphery above the opening of the recess 105. Further, as shown in FIG. 13, the vertical side of the fixed plate 212 has a hole 214. The hole 214 is disposed at a position where it is exposed when the flash light emitting unit 100 is in a protruding state. A triangular cross-sectional protrusion 213 is formed on the inner side surface in the vicinity of the opening of the recess 105. The triangular cross-sectional protrusion 213 is a protrusion that protrudes toward the inside of the recess 105. The fixing plate 212 is attached to the main body case 210 by engaging the triangular section protrusion 213 of the main body case 210 with the hole 214 of the fixing plate 212. The shape of the packing 101 is annular. The packing base 101 </ b> B that is a part of the packing 101 is sandwiched between the fixing plate 212 and the main body case 210, so that the packing 101 is fixed to the main body case 210.

  The cross section of the packing 101 in a non-contact state in which the light emitting unit case A110 and the packing 101 are not in contact with each other is substantially L-shaped as shown in FIGS. 12A and 13A. The side in the horizontal direction of the packing 101 constitutes a packing base 101B shown in FIG. The side of the packing 101 in the vertical direction is a portion bent upward from the outer end of the packing base 101B. In the contact state where the light emitting unit case A110 and the packing 101 are in contact, that is, in the housed state, the vertical side of the packing 101 contacts the inner surface of the light emitting unit case A110. Due to the contact between the packing 101 and the inner surface of the light emitting unit case A110, the side in the vertical direction of the packing 101 is bent inward as shown in FIG. Due to the repulsive force of the packing 101 due to this deformation, the packing 101 and the inner surface of the light emitting unit case A110 are in close contact with each other, preventing water from entering from the outside. When the user removes the packing 101, the fixing plate 212 is removed by removing the engagement between the hole 214 of the fixing plate 212 and the triangular cross-sectional protrusion 213 of the main body case 210, and the packing 101 is removed from the main body case 210.
