  However, in electronic devices such as mobile phones and smartphones, with the diversification of usage modes, it is required to make the entire electronic device waterproof, and when a pin insertion hole is provided in the electronic device casing as described above, Due to the structure, the pin insertion hole penetrates inside and outside of the electronic device casing, so that water may enter the electronic device from the pin insertion hole.

  For this reason, in electronic devices that have a structure for operating the switches and the above-mentioned object to be operated for the eject mechanism through the pin insertion hole, it can be waterproofed by inserting a rubber cap around the pin insertion hole. In this case, there is a problem in that the appearance is poor and the cap has to be attached and detached every time it is used, which is inconvenient.

  Therefore, in view of such a conventional problem, the present invention is an electronic device capable of operating an ejection mechanism of a card connector built in through a pin insertion hole formed in the electronic device housing, and the electronic device is simple and suitable. It was made for the purpose of providing a waterproof structure for electronic devices that can be waterproofed.

  The feature of the invention described in claim 1 for solving the conventional problems as described above and achieving an intended object is that a housing installed inside the electronic device housing and a tray from the outside of the electronic device housing. A card tray that is inserted into the housing through the opening for operation, an object to be operated that is movably held on the side of the housing, and an eject mechanism that pushes out the card tray in conjunction with the pushing operation of the object to be operated. In the waterproof structure for an electronic device having a card connector, the card tray has a front lid portion that fits into the opening for the tray, and an annular lid made of an elastic material on the outer periphery of the front lid portion. A pin insertion hole penetrating separately from the opening for the tray, and an operation pin accommodated in the pin insertion hole so as to be movable and not removable. The operation pin is operated by the operation pin, and an annular pin water-stopping member made of an elastic material is fitted to the outer periphery of the operation pin, and the inner surface of the pin insertion hole and the The gap between the operation pin and the outer peripheral surface is in the waterproof structure of the electronic device sealed with the pin water-stopping member.

  According to a second aspect of the present invention, in addition to the configuration of the first aspect, the operated body is integrally provided with a pressed portion that protrudes outward and is pressed by the tip of the operating pin. is there.

  The pin water-stopping member 6 has a circumferential section formed larger than the depth of the water-stopping member fixing groove 52 and protrudes outward from the outer peripheral surface of the slide sealing portion 51 over the entire circumference. 52, and is sandwiched between the inner surface of the pin insertion hole 4 and the outer peripheral surface of the slide sealing portion 51, and seals the gap between the inner surface of the pin insertion hole 4 and the outer peripheral surface of the operation pin 5. Yes.

  As shown in FIGS. 2 and 4, the eject mechanism is configured such that the operated body 3 is held on the side of the housing 22 so as to be movable in the insertion / extraction direction of the card tray 21, and is rotated rearward on the operated body 3 side of the housing 22. A pivot lever 24 is provided so as to be movable.

  The rotating lever 24 is rotated by operating the operated body 3 in the push-in direction, so that the one end 24a of the rotating lever 24 is pressed by the tip of the operated body 3, and accordingly, the rotating lever 24 is rotated. The other end 24b of the lever 24 pushes the rear edge of the card tray 21 in the pulling direction.

  The operated body 3 is formed in an elongated rod shape, and integrally includes a pressed portion 31 that is bent outward at a front end portion, and has an inverted L shape in plan view.

  The pressed portion 31 protrudes to the outside from the outer edge of the front lid portion 212 of the card tray 21 described later, and is arranged at a position aligned with the pin insertion hole 4. The operation object 5 can be pushed by the operation pins 5 accommodated in the pin insertion holes 4 formed separately.

  As shown in FIG. 5, the card tray 21 includes a tray main body 211 in which the card C is accommodated, and a front cover 212 fixed to the front end of the tray main body 211 in a flange shape.
