DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
(Embodiment)
1 and 2 show a waterproof camera as a configuration of an embodiment of an electronic apparatus to which the present invention is applied. 1 is a front panel, 2 is a rear panel, 3 is a front case, and 4 is a rear case.

  In the embodiment, when the waterproof front panel 1 and the rear panel 2 shown in FIG. 1 are removed from the waterproof camera, the waterproof case formed by the resin front case 3 and rear case 4 shown in FIG. 2 is exposed. .

  FIG. 3 is an exploded view of the casing and cover member, and its locking mechanism and release mechanism. 5 is a media slot, 6 is a USB port, 7 is a cover member, 8 is a dial, 9 is a slide member, and 11 is a slide member. Dial mounting screws, 12 a dial retaining washer, 13 a slide guide plate, 14 a cover plate, 15 a torsion coil spring, and 16 a tension spring.

  As shown in the figure, a media slot 5 and a USB (Universal Serial Bus) port 6 are formed on one side of a waterproof housing formed by the front case 3 and the rear case 4 with the openings thereof arranged vertically. . A cover member 7 constituting a waterproof cover that covers the media slot 5 and the USB port 6 is provided, and a dial 8 for restricting or releasing the movement of the cover member 7 by a rotating operation is provided above the cover member 7. Is provided. Furthermore, a slide member 9 that can be engaged with the cover member 7 and can be locked in a state where the cover member 7 covers the media slot 5 and the USB port 6 is provided.

  That is, the cover member 7 has a waterproof lid frame 71 with a lower end attached to the lower side of the USB port 6 so as to be opened and closed by the waterproof lid shaft 72. A waterproof lid rubber packing 73 is attached to the inner surface of the waterproof lid frame 71 with a double-sided tape 74 that is in close contact with the media slot 5 and the peripheral surface of the USB port 6 and waterproofs. Further, an engagement groove 75 that locks the slide member 9 is integrally formed at the upper end portion of the waterproof lid frame 71.

  The dial 8 is rotated on a mounting boss 10 provided above the media slot 5 on one side of a waterproof casing (front case 3 and rear case 4) with a dial retaining screw 11 and a dial retaining washer 12 interposed therebetween. Mounted operably. As shown in FIGS. 4 and 5, an engagement claw 81 that engages with the slide member 9 and a spring engagement portion 82 are formed inside the dial 8.

  A slide member 9, a slide guide plate 13, a cover plate 14, and a torsion coil spring 15 are stacked around the mounting boss 10. The slide member 9 is held so as to be slidable in the vertical direction with respect to the slide guide plate 13 that is engaged and fixed above the mounting boss 10 of the waterproof casing (the front case 3 and the rear case 4). The cover plate 14 accommodates and holds the torsion coil spring 15 in the dial 8. One end of the torsion coil spring 15 is inserted into an engagement portion such as a hole formed around the mounting boss 10 of the waterproof casing (the front case 3 and the rear case 4) through the cutout portion of the cover plate 14 and fixed. On the other hand, the other end is inserted into and engaged with a spring engaging portion 82 inside the dial 8.

  As shown in FIGS. 6 and 7, the slide member 9 has a lock claw 91 that engages with the engagement groove 75 of the cover member 7 screwed to the lower end portion and is engaged with the intermediate portion protruding to the front side. A pin 92 and a spring holding pin 93 protruding inside the upper end portion are integrally formed. The engaging pin 92 engages with the engaging claw 81 inside the dial 8 when the dial 8 is rotated. Further, the tension spring 16 is stretched over a spring holding pin 93 and a spring holding pin 17 provided above the mounting boss 10 of the waterproof housing (front case 3 and rear case 4).

  In the above, as shown in FIG. 1, the dial 8 has its upper and lower parts hidden by the shape of the exterior panels (front panel 1 and rear panel 2), and only the front and rear parts are exposed, thereby avoiding inadvertent operations. It has become a thing.

  Next, FIG. 8 shows a front view (a) and a side view (b) of the housing, and FIG. 9 shows an opening process 1 (start of dial rotation) of the cover member 7, and FIG. ) Shows a cross section taken along the line AA in FIG. 8, and FIG. 9B shows a cross section taken along the line BB in FIG.

  As illustrated, the locked state in which the lock claw 91 of the slide member 9 is engaged with the engagement groove 75 of the cover member 7 is maintained by the tension spring 16 that biases the slide member 9 downward. In this locked state, the engaging claw 81 of the dial 8 is located at a position away from the engaging pin 92 of the slide member 9. Accordingly, in the waterproof lock state in which the cover member 7 is closed, there is play as the engagement claw 81 and the engagement pin 92 are separated from each other. Is returned to the position shown.

  When the dial 8 is rotated clockwise as indicated by an arrow, the engaging claw 81 of the dial 8 comes into contact with the engaging pin 92 of the slide member 9, and the slide member 9 is moved upward as indicated by the arrow. Begin to slide into.

  FIG. 10 shows the opening process 2 of the cover member 7 (start of slide interlocking). As shown in the figure, when the engaging claw 81 comes into contact with the engaging pin 92, the spring holding pin 93 of the slide member 9 and the waterproof member 9 are waterproofed. The tension spring 16 stretched over the spring holding pin 17 of the housing starts to extend, and the slide member 9 starts to slide upward.

  FIG. 11 shows the opening process 3 (lid unlocking) of the cover member 7. As shown in the figure, the engaging claw 81 pushes up the engaging pin 92 by the rotation operation of the dial 8, and the tension spring 16 is extended. When the slide member 9 slides upward, the lock claw 91 of the slide member 9 disengages the engagement groove 75 of the cover member 7, and the lock is released. Accordingly, the cover member 7 swings around the lower waterproof lid shaft 72 as a fulcrum due to the elasticity of the waterproof lid rubber packing 73 and opens the media slot 5 and the USB port 6.

  As described above, the engagement claw 81 provided on the dial 8, the engagement pin 92 provided on the slide member 9, and the torsion coil spring 15 that urges the dial 8 in the returning direction constitute a lock release mechanism. .

  FIG. 12 shows the closing process 1 (lid closing start) of the cover member 7. The slide member 9 is kept biased downward by the tension spring 16, and the dial 8 is biased by the torsion coil spring 15. Is returned to the original position. From this state, the cover member 7 can be closed with one touch.

  FIG. 13 shows the closing process 2 of the cover member 7 (start of slide interlocking). As shown in the figure, the upper end of the cover member 7 comes into contact with the lock claw 91 of the slide member 9, and the tension spring 16 begins to extend. The slide member 9 starts to slide upward.

  FIG. 14 shows the closing process 3 (lid lock) of the cover member 7. When the lock claw 91 gets over the upper end of the cover member 7, the lock claw 91 is covered by the urging of the tension spring 16 as shown in the figure. The locked state engaged with the engaging groove 75 of the member 7 is maintained.

  Thus, the cover member 7 can be closed with one touch.

  As described above, according to the waterproof camera of the embodiment, the slide member 9 that can be locked in a state in which the cover member 7 covers the openings (the media slot 5 and the USB port 6) of the waterproof housing (the front case 3 and the rear case 4). Then, the dial 8 for restricting or releasing the movement of the cover member 7 by the rotation operation, and the dial 8 is engaged with the slide member 9 by the rotation operation of the dial 8 at a predetermined angle or more, and the slide member 9 is slid. By providing the lock release mechanism (the engagement claw 81 of the dial 8 and the engagement pin 92 of the slide member 9) that releases the locked state where the cover member 7 covers the opening, the dial lock type cover member 7 is provided. Not only can it be locked securely, but it can also be easily opened and closed.

(Modification)
In the above embodiment, the camera is used. However, the present invention is not limited to this, and may be a device such as a mobile phone including the camera.
Also, the shape of the housing, opening, cover member, dial, and slide member is arbitrary, and other specific details such as the structure of the unlocking mechanism can be changed as appropriate. It is.
