  According to the present invention, since it has the above-described features, the following can be achieved.

That is, an electronic device having a first main surface provided with a touch panel monitor, a second main surface facing the first main surface, and a side surface connecting the first main surface and the second main surface. The waterproof case used for the electronic device includes a first cover portion that covers the second main surface and a first engagement portion that engages with the electronic device, and at least the touch panel monitor is attached while the electronic device is mounted. Covering a first main surface including a first case half detachably attached to the electronic device so as to be opened toward the side, and a touch panel monitor of the electronic device to which the first case half is attached; A second cover portion configured to allow a touch operation on the touch panel monitor in a state where the first main surface is covered; and a second engagement portion engaged with the first case half. A second case half that is detachably attached to an electronic device to which the first case half is attached And the electronic device is watertightly accommodated by the first case half and the second case half, so that the first time the electronic device is not required for waterproof performance. By mounting only the case half, it can be used as a so-called protector case that protects the electronic device from scratches and dirt. In addition, in this case, since the touch panel monitor is opened to the outside and can be directly touched, the touch panel operation can be comfortably performed with good monitor visibility.
And when waterproof performance is required, it can mount | wear with the 2nd case half from the top with the state which mounted | wore with the 1st case half in the electronic device. In this case, the touch panel monitor is covered with the second case half, the touch panel monitor can be touched from the outside of the second cover, and the electronic device can be in a watertight state. That is, it becomes possible to make a waterproof state quickly.

Is formed of a transparent or light-transmitting flexible and elastic material, the second case half can be used as a so-called waterproof cover that covers the electronic device in a watertight manner. The first case half has a first seal portion that is combined with the second seal portion of the second case half to be watertight, and serves as a cap for the waterproof cover. Good water resistance is obtained because it is half.
For example, if the waterproof cover has a structure in which the cap is attached after the waterproof cover is attached, the cap may be removed during use of the electronic device. However, in the present invention, since the second case half corresponding to the waterproof cover is mounted after the first case half corresponding to the cap is mounted on the electronic device, the second case half is mounted. As long as the first case half is not removed, the first case half is not separated from the electronic device, and there is no possibility that the cap may be removed during use of the electronic device.

  Further, since the first seal part is a continuous endless convex part and the second seal part is a flat part or a continuous endless concave part, a reliable waterproof effect can be obtained.

  Moreover, since the 1st seal | sticker part is a continuous endless recessed part and the 2nd seal | sticker part is a continuous endless convex part, a reliable waterproof effect can be acquired.

When the second case half is attached to the second case half, the second case half is stretched, and a strong inward force is applied to the side surface of the second case half. And the 2nd seal part and 1st seal part which are located in the side of the 2nd case half which applied strong force press-contact, and a big waterproofing effect can be acquired.

  The touch panel monitor is a capacitive touch panel, and the second cover is configured to cover the touch panel monitor in a stretched state. And since it becomes thin when the 2nd cover part is extended, a capacitive touch panel can be touch-operated more sensitively than the original thickness.

  In addition, a frame-like spacer projection is formed in the vicinity of the outer edge of the touch panel monitor on the second cover portion, and a gap is provided between the second cover portion and the touch panel monitor by the spacer projection. Therefore, the gap between the second cover portion and the touch panel monitor can be prevented by this gap, and the visibility of the monitor can be enhanced.

  Further, since the frame-shaped spacer protrusion is discontinuous and is configured in a divided frame shape, there is a possibility that the continuous frame shape may hinder the extension of the inner surface portion of the frame. However, by dividing the frame portion, the touch monitor surface inside the frame can also be stretched without interruption.

  Further, in a state where the second case half is attached to the electronic device to which the first case half is attached, the operation unit provided in the second case opposite to the operation button is used for the outside of the second case. Therefore, when the second case half is attached, the operation unit can be operated comfortably.

In addition, the electronic device, the first case half, and the second case half are formed in a substantially rectangular shape, and corner guide portions that bulge outward are formed at the four corners of the second case half. Therefore, when the electronic device with the first case half attached is attached to the second case half, the four corners of the first case half correspond to the four corners of the corner guide part. It is guided smoothly by the inner surface. In addition, when the electronic device to which the first case half is attached is displaced in a state where it is attached to the second case half, by pinching and pulling the corner guide portion with a finger, The electronic device to which the first case half is attached can be moved to a predetermined position inside the second case half.
By the way, since the operation buttons of the electronic device and the operation unit provided in the second case cannot be operated unless the positions of the operation buttons are aligned with each other, a firm alignment is required. , Can be surely aligned.
For example, when an electronic device equipped with a waterproof case falls from a corner, the corner guide portion bulges outward from the corner, so that the electronic device can be protected from the impact of dropping.

  The second main surface of the electronic device is provided with the imaging lens of the camera for imaging, and the imaging lens window is provided in a watertight manner at the position of the first case half facing the imaging lens. A camera for photographing an electronic device can be used while maintaining the state.

With the above configuration, the portable terminal 100 can be protected from scratches and dirt by attaching the protector case 2 to the portable terminal 100. Further, since the touch panel monitor 102, operation buttons, and the like are not covered by the protector case 2 attached thereto, direct operation and the like can be performed. That is, when the portable terminal 100 is normally used and the waterproof function is not required, only the protector case 2 can be attached to the portable terminal 100 and used without impairing the operability.
In this embodiment, since the protector case 2 is made of a rigid material, the portable terminal 100 can be protected from external force.

Further, since the continuous protrusion 2k is formed so as to protrude outward along the edge of the side surface of the protector case 2 with a predetermined width B, the fingertip can easily be hooked on the continuous protrusion 2k. That is, when the protector case 2 is attached, the portable terminal 100 can be held more reliably and the gripping property is improved than when the portable terminal 100 itself is held.
The continuous protrusion 2k functions as a waterproof structure of the waterproof case 1 in association with the waterproof cover 3, and details thereof will be described later.

  In the present embodiment, the U-shaped opening 2g is provided on the side surface of the protector case 2 so as to open the vicinity of the operation buttons and terminals of the portable terminal 100. For example, there are operation buttons and terminals that are not normally used. In that case, the U-shaped opening 2g may not be provided in that portion, and the operation buttons and terminals may be protected from misuse.

Next, the waterproof cover 3 (second case half) constituting another part of the waterproof case 1 of the present embodiment will be described.
As shown in FIG. 3, the waterproof cover 3 includes a front surface 3a, which is a main surface, an upper side surface 3b, a lower side surface 3c, a left side surface 3d, a right side surface 3e, and a rear surface 3f (second engaging portion). I have. These six surfaces form a rectangular box-like structure having an opening 3g on the rear surface 3f. As shown in FIG. 4, by inserting the portable terminal 100 with the protector case 2 into the opening 3g of the waterproof cover 3, as shown in FIGS. It is configured to be able to.
In this embodiment, the waterproof cover 3 is transparent or light-transmitting, such as silicon rubber or urethane rubber, and is flexible so that the opening 3g can be expanded and contracted so that the portable terminal 100 can be accommodated therein. It is made of some elastic material.

As shown in FIGS. 3 and 5, an operation button operation portion 3 h is formed at a position on the right side of the front surface 3 a facing the operation button 103. A release button operation unit 3i and a seesaw key operation unit 3j are formed at positions of the upper side surface 3b facing the release button 106 and the seesaw key 107, respectively. A power on / off operation button operation unit 3k is formed at a position of the left side surface 3d facing the power on / off operation button 110. Since it is comprised in this way, these operation buttons of the portable terminal 100 can be operated from the exterior of the waterproof cover 3. FIG.
A lens window hole 3m, which is a through hole, is formed at a position on the upper left side of the rear surface 3f facing the imaging lens window 4 of the protector case 2.

As shown in FIGS. 3 and 5, thick corner guides 3 n are formed at the four corners of the waterproof cover 3 so as to protrude outward from the side surfaces.
As shown in FIG. 4, when the portable terminal 100 with the protector case 2 is inserted into the waterproof cover 3, the corner guide 3 n comes to have the four corners of the protector case 2 positioned at the corners on the inner surface of the corner guide 3 n. To guide.

Even when the accommodation position is shifted, the portable terminal 100 with the protector case 2 attached can be easily moved to a predetermined position of the waterproof cover 3 by pulling the corner guide 3n with a fingertip. In this manner, it is possible to guide the operation unit or the like of the waterproof cover 3 so as to face the operation button or the like of the mobile terminal 100.
Further, since the corner guide 3n is configured to be thick, for example, when the corner guide 3n is accidentally dropped during use, the corner guide 3n absorbs the impact and protects the mobile terminal 100.

  As shown in the partially cutaway cross section of FIG. 3 (b), the thickness of the front surface 3a of the waterproof cover 3 is made thinner than the thickness of the side surfaces 3b to 3e and the rear surface 3f. Moreover, the size of the inner surface of the waterproof cover 3 in a state where it is not accommodated is smaller than that of the portable terminal 100 to which the protector case 2 is attached.

As shown in FIG. 6, the waterproof cover 3 is extended by the portable terminal 100 to which the accommodated protector case 2 is attached. In particular, the thickness of this portion of the front surface 3a of the waterproof cover 3 is other waterproof cover. Since it is thinner than 3, it is stretched relatively large. The stretched front surface 3 a is in close contact with the surface of the touch panel monitor 102 provided on the front surface 101 a of the mobile terminal 100.
Further, the waterproof cover 3 is engaged by the rear surface 3f so as to cover the protector case 2.

The touch panel of the touch panel type monitor 102 is a capacitive type. For example, when a thick sheet is placed on the touch panel type monitor 102 and a touch operation is performed from the thick sheet, the sensitivity is greatly lowered.
In the present embodiment, since the front surface 3a is stretched and thinned, the touch panel can be touch-operated with little reduction in sensitivity.

  In the present embodiment, the front surface 3a of the waterproof cover 3 is stretched in the length direction from 10% to 30% from the original state, and the original thickness of 0.4 mm to 0.8 mm is stretched. Is configured to be 0.3 mm to 0.6 mm. This limitation of the thickness is due to the fact that if the original thickness is reduced, the resin is less likely to enter the mold when the waterproof cover 3 is molded, and if the thickness is increased, the sensitivity is greatly reduced.

As shown in FIG. 6, the entire waterproof cover 3 is stretched, and in particular, the front surface 3 a is greatly stretched. Therefore, a strong force toward the inside acts on the side surface of the waterproof cover 3.
On the other hand, a continuous protrusion 2k is formed on the side surface of the protector case 2 so as to form a contour line that is the maximum outer shape.
If it does so, the inner surface (2nd seal part) of the side surface of the waterproof cover 3 in which the strong force which goes to an inner side will press-contact the continuous protrusion 2g of the protector case 2 so that the inner surface may bite.

That is, a strong waterproof structure is constituted by the continuous protrusion 2 g formed on the protector case 2 and the inner surface of the side surface of the waterproof cover 3.
The waterproof case 1 of the present embodiment has a double waterproof structure, and another waterproof structure different from the waterproof structure constituted by the continuous protrusion 2g of the protector case 2 and the inner surface of the side surface of the waterproof cover 3 is: It has a simpler structure than the above waterproof structure. The simple structure will be described below.
