The Z-axis direction is one direction in which the display 40 extends, and is a direction perpendicular to the X-axis direction. The Y-axis direction is a direction perpendicular to the display 40 and perpendicular to both the X-axis direction and the Z-axis direction. In this specification, the X-axis direction may be referred to as a first direction X, the Z-axis direction may be referred to as a second direction Z, and the Y-axis direction may be referred to as a perpendicular direction Y. One direction in the first direction X is referred to as the +X direction or the right direction. The direction opposite to the +X direction is referred to as the -X direction or leftward. One direction in the second direction Z is referred to as the +Z direction or upward. The direction opposite to the +Z direction is referred to as the -Z direction or downward direction. The direction from the back cover 11 toward the display 40 along the perpendicular direction Y is referred to as the +Y direction, the front, or the near side. The direction opposite to the +Y direction is referred to as the -Y direction, rearward, or back side. The perpendicular direction Y is also the direction in which the first housing 10 and the second housing 20 face each other when the housing C is in the closed state.

As described above, the first housing 10 includes the back cover 11, the peripheral wall 12, and the annular bezel 13. In this embodiment, the back cover 11 is formed into a rectangular plate shape having sides extending in the first direction X and sides extending in the second direction Z. The peripheral wall 12 extends forward from the outer peripheral edge of the back cover 11 (see also FIGS. 5 to 8). The first housing 10 as a whole is formed into a flat box shape that opens toward the front.

Bezel 13 covers the front end of peripheral wall 12 (see also FIGS. 5-8). Furthermore, the bezel 13 prevents the display 40 from falling off from the first housing 10 toward the front. The bezel 13 includes a first bezel 13a, a second bezel 13b, and a pair of third bezels 13c. The first bezel 13a and the second bezel 13b extend in the first direction X. The first bezel 13a and the second bezel 13b are spaced apart from each other in the second direction Z. The first bezel 13a is located above the second bezel 13b. Each of the pair of third bezels 13c extends in the second direction Z. The pair of third bezels 13c connects both ends of the first bezel 13a in the first direction X and both ends of the second bezel 13b in the first direction X. In this embodiment, each of the first to third bezels 13a to 13c is formed into a flat plate shape extending in the first direction X and the second direction Z.

As shown in FIGS. 7 and 8, the hinge 30 according to the present embodiment includes a hinge main body 31 and a hinge shaft 32 connected to the hinge main body 31.

The hinge shaft portion 32 has a rotation axis extending in the first direction X, and is configured to be rotatable around the rotation axis. When the hinge shaft section 32 and the hinge main body section 31 connected to the hinge shaft section 32 rotate, the first housing 10 and the second housing 20 rotate relative to each other around the rotation axis, The housing C opens and closes.

As shown in FIGS. 7 and 8, the hinge 30 (hinge main body portion 31 and hinge shaft portion 32) has a through hole T through which a cable 60, which will be described later, is inserted. The through hole T communicates with the internal space of the first housing 10 and the internal space of the second housing 20.

The display 40 is a device that displays images by converting electrical signals into optical signals. As the display 40, for example, a liquid crystal display, an organic EL (Electro Luminescence) display, etc. can be adopted.

As shown in FIGS. 1 and 5, the first housing 10 houses a display substrate 50 that is electrically connected to the display 40. The display board 50 manages images displayed on the display 40. As shown in FIG. 5, the display 40 and the display substrate 50 according to this embodiment are arranged so as not to overlap each other in the direction Y perpendicular to the surface. In the example of FIG. 5, the display substrate 50 is located below the display 40 and extends in the first direction X. Further, the display substrate 50 is covered with the second bezel 13b when viewed from the direction Y perpendicular to the surface.

As shown in FIG. 1, the portable information processing device 1 includes a display board 50 housed in a first housing 10 and a control board (not shown) such as a motherboard housed in a second housing 20. It has a cable 60 for electrical connection. As shown in FIGS. 3 and 4, the cable 60 includes a plurality of wires 61 and a covering material 62 that bundles and covers the plurality of wires 61. As the wire 61, for example, a conductive material such as a copper wire can be used. As the covering material 62, for example, an insulating material such as resin or insulating tape can be used. In this embodiment, an insulating tape is used as the covering material 62, and the insulating tape is spirally wound so as to bundle and cover the plurality of wires 61.

As shown in FIG. 2, the cable 60 according to the present embodiment includes a connecting portion 60A, a detour portion 60B, a passage portion 60C, and an entry portion 60D. The parts 60A to 60D are continuous in this order in the direction from the display board 50 toward the inside of the second casing 20 (control board). Moreover, the plurality of wires 61 extend continuously from at least the connecting portion 60A to the detour portion 60B and the passage portion 60C without being converted into other conductive members such as FPC (Flexible Printed Circuit). In addition, in this embodiment, the plurality of wires 61 extend continuously from the connection part 60A to the detour part 60B, the passage part 60C, and the entrance part 60D.

The connecting portion 60A is a portion of the cable 60 that is connected to the display board 50. The connecting portion 60A according to the present embodiment is connected to the rear surface of the display substrate 50 and mainly extends in the second direction Z (see also FIG. 5).

The detour portion 60B is a portion of the cable 60 located between the display 40 and the back cover 11 in the direction Y perpendicular to the plane. In other words, the detour portion 60B is a portion of the cable 60 that overlaps with the display 40 in the perpendicular direction Y (see also FIGS. 5 to 8). In this embodiment, in more detail, the detour part 60B includes a first detour part 60Ba that is continuous to the connecting part 60A, a second detour part 60Bb that is continuous to the first detour part 60Ba, and a second detour part 60Bb that is continuous to the second detour part 60Bb. A third detour portion 60Bc is included. The first detour portion 60Ba mainly extends in the second direction Z. The second detour portion 60Bb mainly extends in the first direction X. The third detour portion 60Bc mainly extends in the second direction Z. That is, the detour portion 60B according to the present embodiment extends in a U-shape when viewed from the perpendicular direction Y.

The entry portion 60D is a portion of the cable 60 that enters into the second housing 20 (see also FIG. 6). That is, the entrance portion 60D is located inside the second housing 20.

The passage portion 60C is a portion that connects the detour portion 60B (third detour portion 60Bc) and the entrance portion 60D. The passage portion 60C extends to pass through the inside of the hinge 30 (through hole T). In this embodiment, in more detail, the passage part 60C includes an extension part 60Ca that is continuous with the detour part 60B, and a small diameter part 60Cb that is continuous with the extension part 60Ca and connected to the entrance part 60D. The extending portion 60Ca mainly extends in the second direction Z (see also FIG. 8). At least a portion of the extending portion 60Ca is disposed inside the hinge main body portion 31. The small diameter portion 60Cb is arranged inside the hinge shaft portion 32 (see also FIG. 7). The small diameter portion 60Cb mainly extends in the first direction X along the hinge shaft portion 32.

The cable 60 according to this embodiment has a flat shape at the detour portion 60B. In other words, in the detour portion 60B, the thickness L1 of the cable 60 is smaller than the width L2 of the cable 60 (see FIG. 3). In particular, in the examples of FIGS. 3, 6, and 7, the plurality of wires 61 are lined up in a row in the width direction of the cable 60 in the detour portion 60B. Further, the cable 60 is arranged such that the thickness direction of the cable 60 and the perpendicular direction Y substantially coincide with each other in the detour portion 60B. Note that the term "approximately matching" includes a case where the thickness direction of the cable 60 is inclined with respect to the perpendicular direction Y to such an extent that the cable 60 does not interfere with the display 40 or the back cover 11.

For example, as shown in FIGS. 3, 6, and 7, in the second detour portion 60Bb, the dimension of the cable 60 in the perpendicular direction Y (the thickness L1 of the cable 60) is the same as the dimension of the cable 60 in the second direction Z. (width L2 of cable 60). Further, in the second detour portion 60Bb, the plurality of wires 61 are lined up in a line in the second direction Z.

Although not shown, in the first detour portion 60Ba and the third detour portion 60Bc, the dimension of the cable 60 in the perpendicular direction Y (thickness L1 of the cable 60) is the dimension of the cable 60 in the first direction X (the thickness of the cable 60). width L2). Further, in the first detour portion 60Ba and the third detour portion 60Bc, the plurality of wires 61 are arranged in a line in the first direction X. Note that the plurality of wires 61 according to the present embodiment are arranged in a line in the first direction X also in the connecting portion 60A and the extending portion 60Ca. That is, the cable 60 according to the present embodiment has a flat shape also in the connecting portion 60A and the extending portion 60Ca.

On the other hand, as shown in FIGS. 4 and 7, the plurality of wires 61 according to the present embodiment are not lined up in a line inside the hinge shaft portion 32 (small diameter portion 60Cb). Thereby, the diameter of the cable 60 can be reduced in the small diameter portion 60Cb, and the cable 60 can be easily inserted into the hinge shaft portion 32. The cable 60 according to this embodiment has a circular shape when viewed in cross section at the small diameter portion 60Cb. In the small diameter portion 60Cb, the plurality of wires 61 may be twisted in a spiral shape, for example.

Next, the operation of the portable information processing device 1 configured as above will be explained.

In the portable information processing device 1 according to the present embodiment, the cable 60 is wired so as to pass between the display 40 and the back cover 11 in the perpendicular direction Y. Thereby, for example, the distance between the display 40 and the peripheral wall 12 in the first direction L3 can be shortened (see FIG. 5). Thereby, the width of the second bezel 13b, that is, the dimension of the second bezel 13b in the second direction Z can be reduced.

In the portable information processing device 1 according to the present embodiment, the cable 60 has a flat shape in the detour portion 60B. In particular, in the illustrated example, the plurality of wires 61 are lined up in a row in the detour portion 60B. As a result, the distance L4 between the display 40 and the back cover 11 in the perpendicular direction Y can be shortened, for example, compared to the case where the cable 60 does not have a flat shape at the detour portion 60B (Fig. 5). Thereby, the thickness of the first housing 10, that is, the dimension of the first housing 10 in the perpendicular direction Y can be reduced.

Furthermore, in the portable information processing device 1 according to the present embodiment, the display 40 and the display substrate 50 do not overlap in the perpendicular direction Y. Thereby, for example, the thickness of the first housing 10 can be reduced compared to a case where the display substrate 50 is arranged behind the display 40.

Further, in the portable information processing device 1 according to the present embodiment, the cable 60 having a plurality of wires 61 and a covering material 62 extends from the display substrate 50 to the inside of the second casing 20. In other words, the cable 60 having the plurality of wires 61 and the covering material 62 extends from the connection portion 60A to the entry portion 60D. Thereby, even when the casing C is opened or closed, the cable 60 is flexibly deformed inside the hinge 30, and the electrical connection between the display board 50 and the inside of the second casing 20 (control board) can be maintained. In particular, in a configuration in which insulating tape is used as the covering material 62, the flexibility of the cable 60 is easily ensured, which not only makes it easier to maintain the electrical connection described above, but also facilitates the wiring work of wiring the cable 60. .

It is also possible to consider a configuration in which FPC and cables are used together, such as using FPC for wiring within the first casing 10 and using cables only for wiring within the hinge 30. On the other hand, in the portable information processing device 1 according to the present embodiment, the FPC and the cable are not used together, so material costs and manufacturing costs can be reduced. In addition, since it is not necessary to provide a space in the first housing 10 for connecting the FPC and the cable, which is required when using the FPC and the cable together, the thickness of the first housing 10 and the bezel 13 can be reduced. It becomes easier to reduce the width.

As described above, the portable information processing device 1 according to the present embodiment includes a first casing 10 having a back cover 11 and a first casing 10 rotatably connected to the first casing 10 by a hinge 30. A second housing 20, a display 40 housed in the first housing 10, a display board 50 housed in the first housing 10 and managing images displayed on the display 40, and a plurality of wires. 61, and a covering material 62 that bundles and covers a plurality of wires 61. A detour portion 60B located between the display 40 and the back cover 11 and extending along the display 40, a passage portion 60C extending to pass through the inside of the hinge 30, and an entry portion located within the second housing 20. portion 60D, and the cable 60 has a flat shape at the detour portion 60B.

With this configuration, the cable 60 is wired to pass between the display 40 and the back cover 11 in the perpendicular direction Y. Therefore, the width of the bezel 13 (second bezel 13b) can be reduced. Furthermore, since the plurality of wires 61 have a flat shape in the detour portion 60B, the thickness of the first housing 10 can be reduced.

Further, the plurality of wires 61 are arranged in a line in the detour portion 60B. With this configuration, the thickness L1 of the cable 60 at the detour portion 60B can be more reliably reduced. Therefore, the thickness of the first housing 10 can be made smaller.

Further, the display 40 and the display substrate 50 do not overlap in the direction Y perpendicular to the plane. With this configuration, the thickness of the first housing 10 can be made smaller.

Further, the covering material 62 is an insulating tape. With this configuration, the flexibility of the cable 60 can be ensured, and the wiring work for wiring the cable 60 can be facilitated.

Note that the technical scope of the present invention is not limited to the embodiments described above, and various changes can be made without departing from the spirit of the present invention.

For example, display substrate 50 may not be located below display 40. Display substrate 50 may be located above display 40, for example. In other words, the display substrate 50 may be arranged so as to overlap the first bezel 13a when viewed from the perpendicular direction Y. Even in this case, the width of the bezel 13 (first bezel 13a) can be reduced by wiring the cable 60 so as to pass between the display 40 and the back cover 11 in the perpendicular direction Y. Alternatively, the display substrate 50 may be located on the right or left side of the display 40. In other words, the display substrate 50 may be arranged so as to overlap the third bezel 13c when viewed from the perpendicular direction Y. Also in this case, by wiring the cable 60 as described above, the width of the bezel 13 (third bezel 13c) can be reduced. However, a configuration in which the display substrate 50 is located below the display 40 is preferable because the length of the cable 60 can be shortened and the space required for wiring the cable 60 can be minimized. Note that the display 40 and the display substrate 50 may be arranged so that at least a portion thereof overlaps in the direction Y perpendicular to the surface.

Further, in the detour portion 60B, the plurality of wires 61 do not need to be lined up in a line. As long as the cable 60 has a flat shape, the arrangement of the plurality of wires 61 can be changed as appropriate. For example, in the detour portion 60B, the plurality of wires 61 may be arranged in two rows. Alternatively, in the detour portion 60B, the plurality of wires 61 may not be arranged in a row.

Further, the shape of each part 60A to 60D of the cable 60 is not limited to the shape described in the above embodiment. For example, the detour portion 60B may extend in a curved shape. Also in this case, since the cable 60 has a flat shape in the detour portion 60B, the thickness of the first housing 10 can be reduced. Further, the cable 60 may have a flat shape in the passage portion 60C and the entrance portion 60D.

Further, the configuration of the hinge 30 is not limited to the configuration described in the above embodiment. As long as the casing C can be opened and closed and the cable 60 can be inserted through the hinge 30, the configuration of the hinge 30 can be appropriately selected from known configurations. For example, the hinge main body portion 31 may be connected to the second housing 20 and the hinge shaft portion 32 may be connected to the first housing 10.

Further, the shapes of the first housing 10 and the second housing 20 are not limited to a rectangular box shape. The shapes of the first casing 10 and the second casing 20 can be changed as appropriate as long as they can accommodate the display 40, control board, and the like. Furthermore, the shape of the display 40 is not limited to a plate shape. For example, display 40 may be curved.

In addition, the components in the above-described embodiments may be replaced with well-known components as appropriate without departing from the spirit of the present invention, and the above-described embodiments and modifications may be combined as appropriate.
