  By the way, in an electronic device that exposes the touch panel to the outside of the housing, a resin packing or the like is installed in order to prevent foreign matter from entering the housing from the joint between the housing and the touch panel. Some packings use, for example, an adhesive member between a housing and a touch panel. Such a packing needs to be formed with a certain width in order to exhibit, for example, an adhesive strength between the housing and the touch panel and a foreign matter mixing prevention function. The portion where the packing is interposed cannot transmit the image from the display means, and the function of the touch panel cannot be used. Therefore, the effective range of the touch panel and the display means is narrowed, and the frame portion on the periphery of the display portion of the electronic device There is a problem that becomes larger.

  Moreover, in order to prevent damage due to impact such as dropping, for example, the casing of the electronic device needs to be thickly formed around the installed touch panel and on which the touch panel is placed. The touch panel installed exposed outside the case cannot be used for display and input functions due to separation from the case or damage to the surface part when it receives an external impact such as dropping an electronic device. There is a fear.

Another object of the disclosed technique is to reduce the size of the housing structure with respect to the display area of an electronic device including a touch panel.

In order to achieve the above object, one aspect of the configuration of the present disclosure includes a touch panel, a rear case, and a front case. The rear case is formed with a wall portion extending partly or entirely on the peripheral side of the touch panel. The front case straddles the display surface side of the touch panel and the wall portion, and is brought into contact with a part of the wall portion and joined to the rear case. The front case has a display window section separated from the position where the touch panel is disposed by the wall section.

  According to the electronic device of the present disclosure, one of the following effects can be obtained.

  (1) By extending the wall part to the peripheral side of the touch panel and installing the front case across the touch panel and the wall part, the installation surface of the touch panel is not exposed to the outside, and the joining distance between the front case and the rear case As a result, the foreign matter mixing prevention function and the housing strength can be maintained.

  (2) The front case and the rear case can be joined on the peripheral side of the touch panel to maintain the foreign substance contamination prevention function and the housing strength, and the rear case can be made narrow, so that the display function of the electronic device can be narrowed. .

  (3) By arranging the front case on the front surface side of the touch panel and bonding the touch panel to the inner wall side, the bonding area can be increased, and the touch panel holding function and the external impact protection function can be improved.

  <About the housing structure of the electronic device 2>

  The front case 4 is an example of the front case of the present disclosure, and is formed of, for example, a resin material having a high transmittance such as a transparent color in order to transmit a display image from the LCD display device 10. In the front case 4, the touch panel 8 is bonded to the inner wall side of the flat portion 14 via an adhesive member (not shown). The adhesive member is, for example, a transparent color, and is applied to the flat surface portion of the touch panel 8 along the entire surface or the peripheral side.

  The peripheral edge portion 16 of the front case 4 is bent in a direction perpendicular to the plane portion 14 or an angle direction approximate thereto, and becomes a part of the case side surface portion of the electronic device 2. In the front case 4, the flat surface portion 14 and the peripheral edge portion 16 are installed across a part of the end portion side of the back surface case 6. That is, the flat surface portion 14 and the peripheral edge portion 16 of the front case 4 are in a joined state with respect to the end side surface of the back case 6. An end portion of the front case 4 is connected to a part of the back case 6 on the side surface side of the electronic device 2, for example. For example, the front case 4 and the back case 6 may be formed with a locking part (not shown) or connected with an external locking part.

  The back case 6 is an example of the rear case of the present disclosure, and for example, a rib 18 that extends to the peripheral side of the touch panel 8 installed on the flat portion 14 of the front case 4 is formed on a part of the front end side. The rib 18 is an example of a wall portion that sets the display window portion 20 by dividing the flat portion 14 by contacting the front case 4, and is formed along a part or the entire circumference of the touch panel 8. That is, the rib 18 shows a boundary portion of the touch panel 8 by the outer shape of the contact portion or its shadow and color being in a transparent state on the flat portion 14 of the front case 4 formed of a transparent color or a material having high transmittance. . The outer peripheral portion of the back case 6 is coated with a paint or a colored tape so as not to transmit light to the inside of the housing.

  Thereby, the front case 4 is a part of the flat surface portion 14 divided by the ribs 18, and the display window portion 20 is set in a portion where the touch panel 8 is disposed. Since the rear case 6 is not joined to the display window portion 20, the touch panel 8 and the LCD display device 10 are transmitted, and the display image is transmitted from the plane portion 14. Further, the portions other than the display window portion 20 of the flat portion 14 are joined to the back case 6 and the colored paint applied to the back case 6 is transmitted, so that the outer shape and shadow of the functional components inside the housing or It becomes the edge part 22 which does not permeate | transmit light.

  The front case 4 of the electronic device 2 is joined to a part of the rear case 6 at a portion other than the display window portion 20, and the inside of the housing is externally transmitted by transmitting the coloring of the rear case 6 to the outside. Prevents visual inspection.

  <Junction between front case 4 and rear case 6>

  In the front case 4, a part of the flat portion 14 and the peripheral edge portion 16 are joined to the exterior side of the rib 18 of the back case 6. The back case 6 has, for example, a recess 24 formed in a part on the exterior side of the rib 18, and the peripheral edge 16 of the front case 4 is disposed in the recess 24, so that The connection surfaces of the front case 4 and the rear case 6 are made to coincide.

  The length of the peripheral edge 16 of the front case 4 may be set arbitrarily, for example. For example, as the length of the joint portion between the rib 18 and the front case 4 increases, the connection strength of the front case 4 to the rear case 6 increases. In addition, since the joining portion becomes longer, the electronic device 2 has a longer entry path from the outside of the housing to the inside, and the function of preventing foreign matter contamination is enhanced.

  Further, a locking recess 26 for locking the rib 18 is formed on a part of the inner wall side of the front case 4, and the rib 18 is disposed inside the locking recess 26, so that the front case 4 And the rear case 6 are prevented from being displaced in the plane direction.

  In addition, the electronic device 2 includes a battery and a functional component (not shown) on the back case 6 side, for example.

  According to such a configuration, the following effects can be obtained.

(1) By extending the rib 18 of the back case 6 to the peripheral side of the touch panel 8 and installing the front case 4 across the touch panel 8 and the rib 18, the joining distance between the front case 4 and the back case 6 is long. Thus, mixing of foreign matters can be prevented and the strength of the housing can be maintained.

(2) The front case 4 and the back case 6 are joined on the peripheral side of the touch panel 8 to maintain the foreign matter mixing prevention function and the housing strength, and the back case 6 is not formed wide. A narrow frame can be achieved.

(3) By arranging the front case 4 on the front surface side of the touch panel 8 and bonding the touch panel 8 to the inner wall side, the adhesion area can be increased, and the function of holding the touch panel 8 and the impact protection function from the outside can be achieved. Improvement can be achieved.

(4) Since the display window portion 20 is divided by the ribs 18 and no gap is generated at the boundary portion between the touch panel 8 and the housing, the appearance can be improved.

(5) Since the front case 4 formed of a highly transmissive member transmits the color colored on the back case 6, it is not necessary to separate the boundary portion of the display window portion 20, thereby simplifying the manufacturing process. In addition, the section of the display area can be clarified.

  (6) Even when it is difficult to attach an in-mold film or the like to the bent portion between the flat surface portion 14 and the peripheral edge portion 16 of the front case 4 due to downsizing of the electronic device 2 and narrowing of the frame portion, the electronic device 2 It is possible to prevent the internal parts from being exposed to the outside.
