Become. In this watertight state, the portable terminal 100 is fixed at a predetermined position and stored in a watertight manner. Further, the front surface of the touch panel monitor 103 of the mobile terminal 100 and the back surface of the window portion 7 provided in the front case 3 are in close contact with each other.

  The details of the waterproof structure in the present embodiment and the touch panel operation in the watertight state will be described below.

In FIG. 1, when the portable terminal 100 is attached to the rear case 4 as indicated by an arrow, the cushion 13 supports the rear surface 101 b of the portable terminal 100.
Next, when the front case 3 is rotated to cover the opening surface of the rear case 4 so as to cover the box, as shown in FIG. 4B, FIG. 5 or FIG. The inner wall of the side surface of 3 and the O-ring 19 provided on the outer wall of the rear case 4 are in pressure contact with each other, thereby forming a watertight state.
The cushion 13 has a predetermined thickness and is crushed by the mobile terminal 100 in a watertight state, and urges the mobile terminal 100 toward the front case 3 with a predetermined force.
As shown in FIG. 6, since the surface of the touch panel type monitor 103 of the mobile terminal 100 protrudes slightly outside the surface of the front surface 101a, the mobile terminal 100 is stored in the waterproof case 1 in a watertight manner. The back surface of the window 7 of the front case 3 and the surface of the touch panel monitor 103 are in close contact with each other.

The touch panel monitor 103 of the portable terminal 100 is a capacitance type monitor. According to the examination result of the applicant, the touch panel can be operated from the outside of the window portion 7 by bringing the window portion 7 into close contact with the surface of the touch panel monitor 103.
Here, the thickness of the window portion 7 is 0.2 mm to 1.2 mm, and more preferably 0.4 mm to 0.6 mm. This is because if the thickness of the window portion 7 is made too thin, the strength becomes weak, and if it is made too thick, the sensitivity of the touch panel monitor 103 becomes worse.

  By configuring as described above, it is possible to directly operate from the outside of the window portion 7 without using a mechanical push button or the like for operating the touch panel monitor 103. For this reason, more complex operations such as multipoint pressing can be performed. As a result, the waterproof case 1 capable of operating the touch panel monitor 103 with a simple configuration can be realized, and a large force is applied to the electronic device from the modified portion by configuring the window portion 7 with a rigid planar member. However, this electronic device can be protected, and the operability and visibility of the touch panel monitor 103 can be secured.

By the way, in a general waterproof case, when attaching a window part to a case, it bonds together from the outside. This is to prevent the window from peeling off when water pressure is applied in water.
However, in the waterproof case 1 of this embodiment, as shown in FIG. 6, the window part 7 is being fixed from the inside of the case. In this embodiment, when the window portion 7 comes into close contact with the touch panel monitor 103 of the portable terminal 100, the portable terminal 100 is biased toward the window portion 7 by the cushion 13, and the window portion 7 is directed from the inside to the outside direction. It is because it receives power.

Here, in this embodiment, the center part of the front case 3 is made difficult to bend.
When the hinge and the buckle are disposed at both ends in the longer direction as in the present embodiment, the window 7 is biased from the inside to the outside as described above, so that the center portion of the front case 3 is outside. There is a risk of bending.
Therefore, in the waterproof case 1 of the present embodiment, as shown in FIG. 1, the upper side surface 3 b and the lower side surface 3 c have a substantially D-shaped shape in which the center portion swells from the end portion in order to prevent the center portion from bending. Even if force is applied, it has a structure that is difficult to bend.

  Furthermore, in this embodiment, even if the center part of the front case 3 bends, it is comprised so that waterproof performance may not fall. FIG. 5 is a cross-sectional view in the direction of arrows BB in FIG. 2, in which the right side shows a cross section at the center and the left side at the end. That is, as shown in FIG. 5, the center width of the flat portion of the inner surface of the side surface in contact with the center of the O-ring 19 is larger (W1> W2). With this configuration, waterproofness is maintained even when the center portion of the front case 3 is bent.

In this embodiment, since it comprised as mentioned above, the waterproof case 1 could be made compact with a small width and a small thickness.
That is, conventionally, since the electronic device is held in the hollow portion of the waterproof case by a cushion or the like, a space for the cushion or the like is required. On the other hand, in the present embodiment, only one cushion is used, and the other is configured to press the touch panel monitor 103 against the window portion 7, so that the configuration can be simplified and the space can be reduced. Moreover, since the part which contact | abuts the window part 7 is a wide area, it can hold | maintain firmly with the anti-slip process processing of the upper surface of the cushion 13. FIG.
Note that the adhesive 8 for fixing the window 7 to the front case 3 is made of an elastic material such as urethane resin, so as to increase the shock absorbing power.

For example, when playing a video using the portable terminal 100 in a bathroom or the like, a loud sound is output using a speaker. In such a case, in the conventional waterproof case, the transparent portion absorbs sound with the soft transparent member, and even if the transparent portion is a rigid flat plate, the sound is trapped in the waterproof case, It was hard to listen to.
In the embodiment of the present invention, in addition to the speaker hole portion, the touch panel monitor and the window portion are in close contact with each other to transmit the vibration, so that there is an effect that sound that is easy to hear and that is easy to hear is reproduced.

In the waterproof case 1 of the present embodiment, the hinge and the buckle are arranged at both ends in the longer direction so that the width of the waterproof case 1 is reduced and looks compact, but the hinge and the buckle in the shorter direction. May be arranged.
Further, in the present embodiment, the cushion 13 is a cylindrical one, but it may be a sheet-like one or a product made by molding in conformity with the outer shape of the mobile terminal 100.

  Furthermore, the headphones can be stored in the waterproof case 1 with the headphones terminal inserted into the headphones terminal 111 of the portable terminal 100 so that the headphones cord can be put out in a watertight manner, and the headphones can be played back in the watertight state. You may do it.

  In the present embodiment, the window portion 7 is assembled to the front case 3. However, for example, the front case 3 and the window portion 7 may be integrally molded with a transparent resin such as polycarbonate resin.
