3 and 6, the wireless communication device 1 includes a first antenna unit 31 and a second antenna unit 35 as shown in FIG. The first antenna unit 31 and the second antenna unit 35 are arranged along the frame portion 21a.

The first antenna unit 31 includes a first antenna 32a, a second antenna 32b, and a first coated cable 33. The first coated cable 33 includes a plurality of cables, that is, a first coaxial cable 33a and a second coaxial cable 33b. The number of coaxial cables matches the number of antennas. As shown in FIG. 8, a connection terminal 33a1 is provided at the tip of the first coaxial cable 33a and is connected to the first antenna 32a. Although not shown in the figure, a connection terminal is also provided at the tip of the second coaxial cable 33b and is connected to the second antenna 32b. The first antenna 32a and the second antenna 32b are arranged on the upper edge portion 21a1 of the frame portion 21a, and the first covered cable 33 is mounted along the right edge portion 21a3 from the upper edge portion 21a1. The first coated cable 33 reaches the inside of the main body 10 by passing through the main body side hinge 13 and the display side hinge 24.

The second antenna unit 35 includes a third antenna 36a, a fourth antenna 36b, a fifth antenna 36c, and a second covered cable 37. The second coated cable 37 includes a plurality of cables, that is, a third coaxial cable 37a, a fourth coaxial cable 37b, and a fifth coaxial cable 37c. The number of coaxial cables matches the number of antennas. Although not shown in the figure, connection terminals are provided at the tip ends of the third coaxial cable 37a to the fifth coaxial cable 37c, and are connected to the third antenna 36a, the fourth antenna 36b, and the fifth antenna 36c, respectively. Has been done. The third antenna 36a, the fourth antenna 36b, and the fifth antenna 36c are arranged at the upper edge portion 21a1 of the frame portion 21a, and the second covered cable 37 extends from the upper edge portion 21a1 to the left edge portion 21a2. It is installed. The second coated cable 37 reaches the inside of the main body 10 by passing through the main body side hinge 13 and the display side hinge 24. A camera 39 is installed at the center of the upper edge 21a1 of the frame 21a.

Referring to FIG. 5A, the first coated cable 33 includes a first coaxial cable 33a and a second coaxial cable 33b that are aligned along the thickness direction of the display unit 20. The first coaxial cable 33a and the second coaxial cable 33b are collectively covered with a cushioning material 34. The material of the cushioning material 34 is selected to have elasticity that can appropriately absorb the impact on the display unit 22. That is, if it is too soft, the shock cannot be absorbed, and if it is too hard, the display unit 22 will be damaged, so an appropriate material is selected from these viewpoints. In this embodiment, VERSAFIT V2 manufactured by Tyco Electronics Japan LLC is used. The cushioning material 34 includes a first smooth surface 34a and a second smooth surface 34b. The first smooth surface 34 a faces the inner surface of the back cover 21 and serves as an adhesive surface to the back cover 21. Referring to FIG. 7B, the first smooth surface 34 a is bonded inside the back cover 21 via the double-sided tape 40. Note that the double-sided tape 40 may be bonded by an adhesive.

Although the cross-sectional shape of the first coaxial cable 33a and the cross-sectional shape of the second coaxial cable 33b are circular, respectively, by covering the first coaxial cable 33a and the second coaxial cable 33b with the cushioning material 34, The cross-sectional shape of the coated cable 33 is rectangular. Therefore, the positioning of the first covered cable 33 inside the back cover 21 is easy. For example, in order to bond the first smooth surface 34a to the inside of the back cover 21, a mark with marking lines is provided inside the back cover 21. Thus, in order to install the first coated cable 33 in the back cover 21, for example, a rib or the like for holding the first coated cable 33 is formed, and the first coated cable 33 is provided along the rib or the like. It is not necessary to install. That is, since the first coated cable 33 has the first smooth surface 34a, the first coated cable 33 can be installed in the back cover 21 in a stable state, so that the ribs and the like can be eliminated. Therefore, a dimensional margin is created in the right edge portion 21a3. As a result, the right edge portion 21a3 can be narrowed.

Further, since the first coated cable 33 itself is provided with the cushioning material 34 and is installed along the display unit 22, it is not necessary to provide a cushioning material separate from the first coated cable 33. This point also causes a dimensional margin in the right edge portion 21a3. As a result, the right edge portion 21a3 can be narrowed.

That is, referring to FIG. 7B, the back cover 21 includes a side wall portion 211 and a support wall 212 that is a portion that supports the display unit 22 inside thereof. Then, the convex portion 22a11 of the frame portion 22a1 included in the display unit 22 is fitted between the side wall portion 211 and the support wall 212. In such a state, the display unit 22 is fixed to the back cover 21 by fixing a nail or the like. At this time, the distance between the support wall 212 and the first coated cable 33 is S1, but S1 is set because there is no other structure between the support wall 212 and the first coated cable 33. It can be shortened. As a result, the right edge portion 21a3 can be narrowed.

Further, the first coaxial cable 33a and the second coaxial cable 33b are aligned along the thickness direction of the display unit 20, and are not aligned in the plane direction of the display unit 20. Also in this respect, the right edge portion 21a3 can be narrowed.

Although the first coated cable 33 includes the second smooth surface 34b on the back surface of the first smooth surface 34a, in the present embodiment, the second smooth surface 34b includes the frame portion 22a1 of the display unit 22 and other parts. It is said that it is not in contact with the place. This is because the dimension of the display unit 20 in the thickness direction is shorter than that of the second coated cable 37 described later. However, since the first coated cable 33 is adhered over almost the entire area of the right edge portion 21a3, the first coated cable 33 is accommodated in the rear cover 21 in a stable state, and the occurrence of biting during assembly is also avoided. Further, a buffer function for the display unit 22 can be exerted.

Referring to FIG. 5B, the second coated cable 37 includes a third coaxial cable 37a, a fourth coaxial cable 37b, and a fifth coaxial cable 37c that are aligned along the thickness direction of the display unit 20. . The third coaxial cable 37a to the fifth coaxial cable 37c are collectively covered with a cushioning material 38. As the material of the cushioning material 38, as in the case of the cushioning material 34, VERSAFIT V2 manufactured by Tyco Electronics Japan LLC is used. The cushioning material 38 includes a first smooth surface 38a and a second smooth surface 38b. The first smooth surface 38 a faces the inner surface of the back cover 21 and serves as an adhesive surface to the back cover 21. Referring to FIG. 7A, the first smooth surface 38 a is adhered inside the back cover 21 via the double-sided tape 40. Note that the double-sided tape 40 may be bonded by an adhesive.

Although the cross-sectional shapes of the third coaxial cable 37a to the fifth coaxial cable 37c are all circular, by covering the third coaxial cable 37a to the fifth coaxial cable 37c with the cushioning material 38, the second coating is performed. The cross-sectional shape of the cable 37 is rectangular. Therefore, the positioning of the second covered cable 37 within the back cover 21 is easy. For example, in order to bond the first smooth surface 38a to the inside of the back cover 21, a mark with marking lines is provided inside the back cover 21. Thus, in order to install the second coated cable 37 in the back cover 21, for example, a rib or the like for holding the second coated cable 37 is formed, and the second coated cable 37 is provided along the rib or the like. It is not necessary to install. Further, a second smooth surface 38b is provided on the back surface of the first smooth surface 38a, and this second smooth surface 38b serves as a positioning surface for the display unit 22. The second smooth surface 38b is positioned and bonded to the frame portion 22a1 of the display unit 22 via the double-sided tape 40. That is, since the second coated cable 37 has the first smooth surface 38a and further has the second smooth surface 38b, the second coated cable 37 can be installed in the back cover 21 in a stable state, so that ribs and the like can be eliminated. . Therefore, the left edge portion 21a2 has a dimensional margin. As a result, it is possible to narrow the left edge portion 21a2. In addition, the occurrence of biting during assembly is also avoided. Further, a buffer function for the display unit 22 can be exerted. An adhesive may be used to bond the second smooth surface 38b and the frame portion 22a1.

Further, since the second coated cable 37 itself is provided with the cushioning material 38 and is installed along the display unit 22, it is not necessary to provide a cushioning material separate from the first coated cable 33. This point also causes a dimensional margin in the right edge portion 21a3. As a result, it is possible to narrow the left edge portion 21a2.

That is, referring to FIG. 7A, the back cover 21 includes a side wall portion 211 and a support wall 212 that is a portion that supports the display unit 22 inside thereof. Then, the convex portion 22a11 of the frame portion 22a1 included in the display unit 22 is fitted between the side wall portion 211 and the support wall 212. In such a state, the display unit 22 is fixed to the back cover 21 by fixing a nail or the like. At this time, the distance between the support wall 212 and the first coated cable 33 is S2, but since there is no other structure between the support wall 212 and the first coated cable 33, S2 is set to S2. It can be shortened. As a result, the left edge portion 21a2 can be narrowed.

The third coaxial cable 37a to the fifth coaxial cable 37c are aligned along the thickness direction of the display unit 20, and are not aligned in the plane direction of the display unit 20. Also from this point, the left edge portion 21a2 can be narrowed.

Next, the bending position of the first coated cable 33 corresponding to the corner portion of the frame portion 21a will be described with reference to FIG. In the first coated cable 33, the position where the upper edge portion 21a1 transitions to the right edge portion 21a3 is the bending position. The first covered cable 33 is provided with an open portion 50 in which the cushioning material 34 is divided at the bending position, as shown by further enlarging the Y4 portion in FIG. In the open portion 50, the first coaxial cable 33a and the second coaxial cable 33b are exposed, and the diameter of the first coated cable 33 is reduced in the open portion 50, so that the flexibility of bending is increased. , Easy to bend. By providing such an open portion 50, an excessive load is not applied to the first coated cable 33. Further, if the open portion 50 is not provided, it is conceivable that the first coated cable 33 is pushed by the display main body 22a at the corner portion, and the first coated cable 33 is less likely to adhere to the display main body 22a. By providing the open portion 50, the first coated cable 33 can be easily brought into close contact with the display body 22a. Moreover, disconnection is suppressed. The second coated cable 37 is also provided with a similar open portion.

As described above, according to the wireless communication device 1 of the present embodiment, it is possible to narrow the edge of the display unit 20. Further, since the edge of the display unit 20 can be narrowed, the back cover 21 of the display unit 20 can be downsized, and thus the wireless communication device 1 itself can be downsized. Become.

Furthermore, during assembly, the cable is prevented from floating or twisting, and the cable can be prevented from being caught. As a result, the number of man-hours for forming work is reduced, and the extra man-hours for repair work and assembling work can be reduced. Further, since the first coated cable 33 and the second coated cable 37 themselves are provided with the cushioning material, it is not necessary to separately prepare the cushioning material, and the number of parts can be reduced and the man-hours associated therewith can be reduced. You can Further, when fixing the display main body 22a, the first covered cable 33 and the second covered cable 37 themselves can exert the positioning function, so that it is not necessary to form a positioning shape on the rear cover 21 side, It is expected that the manufacturing yield in the manufacturing process of the cover 21 will be improved.

Further, with reference to FIGS. 9A and 9B, it is possible to further narrow the edge. FIG. 9(A) shows the left edge portion 21a2 of the present embodiment described with reference to FIG. 7(A). In the state shown in FIG. 9(A), the back cover 21 has a support wall 212, and the display unit 22 is fixed to the back cover 21 by nail fixing or the like. At this time, the edge width, which is the distance from the side edge of the display main body 22a to the side edge of the back cover 21, is W0. On the other hand, as shown in FIG. 9B, by eliminating the support wall 212, the edge width can be set to W1, which is shorter than W0. As a result, it is possible to further reduce the size of the wireless communication device 1 and further reduce the size of the wireless communication device 1. The reason why the support wall 212 can be eliminated is that both the first smooth surface 38a and the second smooth surface 38b of the second coated cable 37 can be bonded. That is, the back cover 21 and the frame portion 22a1 of the display unit 22 are bonded and fixed via the second coated cable 37, whereby the support wall 212 can be eliminated. Since the first coated cable 33 includes two coaxial cables, the distance between the first smooth surface 34a and the second smooth surface 34b is narrower than that of the second coated cable 37. In this case, the cushioning material 34 may be used to increase the volume.

Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the specific embodiments, and various modifications within the scope of the gist of the present invention described in the claims. It can be changed.
