  On the back side of the housing 3, a groove portion 31 extending in the vertical direction along the center line of the back surface is formed. The groove part 31 accommodates the antenna 2 so that the rear side 92 of the housing 3 becomes the opening side and the antenna 2 can be taken out from the rear side 92. Further, the groove portion 31 penetrates the upper side 39 included in the back surface of the housing 3, and forms a through portion 32 in the upper portion 91 of the housing 3. That is, the penetrating part 32 is formed on the back side of the upper surface of the housing 3. The through portion 32 serves as an opening for the antenna 2 to protrude from the housing 3 toward the upper side 91 when the antenna 2 is released from storage. In the present invention, the side of the surface of the housing 3 on which the through portion 32 is provided is referred to as the upper portion 91, and the surface on which the opening of the groove portion 31 exists (the surface on which the through portion 32 is provided). The side of “Excluded” is referred to as the rear 92. The direction opposite to the upper side 91 is referred to as the lower side, and the direction opposite to the rear side 92 is referred to as the front side. As described above, the display unit 5 is provided on the front surface of the housing 3, and this is present on the front surface opposite to the antenna 2.

  A pair of hole portions 34 and 35 are present on the wall surface 36 located in the upper portion 91 of the groove portion 31 so as to face each other with the groove portion 31 interposed therebetween. That is, the pair of hole portions 34 and 35 are formed so that one is opposed to the left wall surface 36 and the other is opposed to the right wall surface 36 with the groove portion 31 as the center. A pair of protrusions 24 and 25 formed in the rotating portion 23 of the antenna 2 are inserted into the pair of holes 34 and 35, respectively.

  As a result, the antenna 2 has its tip pointed downward when housed in the groove 31, and from this state, a semicircle is formed with the pair of protrusions 24, 25 existing in the rotating part 23 as the rotation axis. It becomes possible to face upward 91 while rotating as depicted. That is, the antenna 2 can be rotated between the upper 91 side and the groove 31 while passing through the rear 92 side of the housing 3 with the pair of projecting portions 24 and 25 existing in the rotating portion 23 as rotation axes. In the state, it is integrated with the housing 3.

  A cutout portion 37 is formed in a lower portion of the housing 3 located on the extension line of the groove portion 31 so that a user can put a finger on the tip of the antenna 2 for convenience of taking out the antenna 2. . A user can put the finger on the tip of the antenna 2 from the notch 37 and raise the antenna 2 from the groove 31 to release the storage.

  As described above, the pair of holes 34 and 35 are provided on the wall surface 36 located in the upper portion 91 of the groove portion 31, but in the present embodiment, are provided below the upper end of the groove portion 31. As a result, when the antenna 2 is removed from the groove 31 by turning and released, the antenna 2 is located at the same timing as the antenna 2 protruding to the upper side 91 of the housing 3, and the vicinity of the base is the bottom surface 38 of the groove 31. To stop rotating. At this time, the rotation part 23 which is a fundamental part of the antenna 2 exists in a state of being hidden inside the groove part 31. When an external force is applied to the antenna, it is most likely that damage occurs at the joint between the antenna and the housing, where the force is concentrated and at the same time a place with low mechanical strength. I can say that. In this regard, in the present embodiment, as described above, the rotating portion 23 that is the root portion of the antenna 2 is hidden behind the groove portion 31, and therefore, the vicinity of the coupling portion between the antenna 2 and the housing 3 is the groove portion 31. It will be supported by the wall surface 36 and the bottom surface 38 of this, and the damage in this location can be suppressed.

  In the portable wireless device 1 of the present embodiment, a pair of projecting portions 24 and 25 projecting in the left-right direction is provided at the rotating portion 23 that is a base portion of the antenna 2, and the pair of projecting portions 24 and 25 are the groove portions 31. Between the upper 91 side and the groove 31 while the antenna 2 passes through the rear 92 side of the housing 3. It is integrated so that it can rotate. As a result, the antenna 2 can be integrated with the housing 3 in a so-called “both-end” state supported by the protrusions 24 and 25 existing on both the left and right sides, so that the strength can be maintained. Damage can be reduced as compared with a type of antenna that is supported and rotates parallel to the surface of the housing. In addition, since the antenna 2 is housed in the groove 31, it is possible to prevent an external object from coming into direct contact with the antenna 2, so that damage to the antenna 2 can be reduced. Further, the antenna 2 is retracted or retracted while rotating so as to draw a semicircle with the pair of projecting portions 24 and 25 existing in the rotating portion 23 as a rotation axis, so that the antenna itself contracts or extends vertically. As compared with the case of using an antenna that can be stored or released, it is possible to store it more compactly and to reduce damage when performing the operation of storing or releasing the storage.

  In the portable wireless device 1 according to the present embodiment, the tip of the antenna 2 faces downward while the antenna 2 is housed in the groove 31. This corresponds to storing the antenna 2 facing upward 91 in the released state by turning operation. By adopting such a storing method, the antenna 2 is mounted as described above. It is possible to store in a more compact manner and to reduce breakage when performing the storing or releasing operation.

  In the portable wireless device 1 of the present embodiment, the pair of holes 34 and 35 are formed below the upper end of the groove 31, and when the antenna 2 is rotated and taken out from the groove 31, When the vicinity of the root comes into contact with the bottom surface 38 of the groove 31, the antenna 2 stops rotating in a posture of protruding upward 91. As a result, when the antenna 2 is released, the rotating portion 23 that is a coupling portion between the antenna 2 and the housing 3 is hidden inside the groove portion 31 and supported by the wall surface 36 and the bottom surface 38. Damage when the force is applied is suppressed.

  Further, in the portable wireless device 1 of the present embodiment, the display unit 6 serving as an interface with the user exists on the front surface of the housing 3. This means that in the housing 3, the antenna 2 exists on the opposite surface of the display unit 6, so that the entire length of the housing 3 in the height direction is stored for housing the antenna 2. Therefore, the antenna 2 can be sufficiently long.

  Although the present invention has been described above with reference to specific embodiments, the present invention is not limited to the above-described embodiments, and can be implemented with appropriate modifications within the scope of the present invention.

  For example, in the above embodiment, the groove portion 31 for housing the antenna 2 is formed so as to extend in the vertical direction along the center line on the back surface of the housing 3, but the groove portion deviates from the center line on the back surface. It may be formed at a different place.

  In the above embodiment, the groove portion 31 for housing the antenna 2 is formed on the back side of the housing 3. However, the groove portion is formed on any surface such as a side surface or a front surface of the housing. May be.

  Further, in the above embodiment, the cutout portion 37 is formed so that the user can put his / her finger on the tip of the antenna 2 as a convenience for the user to take out the antenna 2. It is good also as the convenience for taking out an antenna using. For such convenience, for example, a mechanism that can rotate the antenna after pushing the rotating portion of the antenna in the housed state is introduced. It is good also as a structure which protrudes. In this case, the antenna can be raised and rotated by placing a finger on the tip of the antenna protruding from below the housing.

  In addition, a pair of small protrusions facing each other so as to sandwich the groove portion 31 at the end on the rear 92 side of the groove portion 31 are provided so that the antenna 2 is not released in an unintended situation when the antenna 2 is stored in the groove portion 31. May be. In this way, when the antenna 2 is housed in the groove 31, the pair of small protrusions fixes the antenna 2 and suppresses the unexpected housing release, while the user releases the antenna 2. In this case, the antenna 2 can be easily released from the pair of small protrusions. The same applies to the case where the antenna 2 is moved from the released state to the stored state. When the user pushes the antenna 2 into the groove 31, the antenna 2 gets over the pair of small protrusions and is stored in the groove 31. The

  In the above embodiment, a speaker is used as the reception device 6, but the reception device may be an earphone or the like.
