Description

The present invention relates to systems, gateway devices, wireless devices, and methods.

Conventionally, for taking in commercial power, for example, one end of a power cord is provided with a plug having two electrodes or three electrodes including a ground electrode, and this plug is inserted into an outlet to connect the power supply line from the switchboard and the power line of the power cord. The other end of such a power cord is connected to, for example, a power supply unit of a personal computer (hereinafter abbreviated as personal computer) to form a power supply system for the personal computer.

Recently, there are many examples of forming a LAN (local area network) with a plurality of personal computers, printers, etc. (hereinbelow, represented by a personal computer for the sake of simplicity) to enable mutual data exchange.
In this case, a personal computer as a terminal forming a LAN naturally requires a power supply and an optical fiber connection. Therefore, the personal computer connects the power supply unit and the outlet with the power cord described above, and connects the optical terminal and the LAN hub with an optical cable.

That is, at least a power cord and an optical cable extend from the personal computer, resulting in wiring congestion.
Therefore, as a countermeasure against wiring congestion, for example, JP-A-2001-266665 and JP-A-2001-318286 propose a composite cable in which a power cord and an optical cable are integrated.
That is, in these composite cables, the power line and the optical fiber are embedded in a common sheath to form a single cable as a whole.

According to the present invention, a system can perform wireless communication with a wireless device having a wireless communication unit including master/slave wireless data communication means.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a diagram showing an embodiment applied to connection between a switchboard and a personal computer.
A power supply line 18 and a ground line 19 extend from the switchboard 10 to an outlet 30 as a female connector attached to the wall surface of the room. The switchboard 10 is connected to a commercial power line 12 .
The switchboard 10 is provided with a HUB 14 for forming a LAN, and an optical fiber 20 extends from the HUB 14 to an outlet 30 .
A composite cable 16 is used between the switchboard 10 and the outlet 30. The composite cable 16 is a VVF (vinyl-insulated vinyl-sheathed flat cable) combined with an optical fiber.

The outlet 30 houses two power electrodes 40 and a ground electrode 45 within a casing 31 formed by a front plate 32 and a frame 36 coupled to its back side.
The frame 36 is made of resin, and the power electrode 40 and the ground electrode 45 are molded on the frame 36 and rise from the bottom wall of the frame toward the front plate 32 .

Since the power electrode 40 and the ground electrode 45 are provided with wire connection portions 41 and 46 at their roots, respectively, to engage the power supply line 18 and the ground line 19 inserted from the outside of the frame 36 in a wedge shape, the power supply line 18 and the ground line 19 are connected to each electrode simply by inserting the stripped core wire, and are difficult to come off.
On the other hand, the tip sides of the power electrode 40 and the ground electrode 45 extend to the vicinity of the front plate 32, respectively, and form conducting portions 42 and 47 that can contact the power electrode and the ground electrode of a plug 60 as a male connector, which will be described later.
The conducting portion 42 of the power electrode 40 of the outlet 30 is formed with a bulging portion 43 projecting toward the contact surface side of the plug with the power electrode.

The ground electrode 45 rises from the bottom wall of the frame 36, is offset by a predetermined amount toward the power electrode 40 along the front plate 32, and has a leading end serving as a conducting portion 47, forming an L shape as a whole.
The front plate 32 is provided with electrode insertion holes 33 and 34 for receiving the power electrodes of the plug and an electrode insertion hole 35 for receiving the ground electrode at portions corresponding to the respective power electrodes 40 (current-carrying portions 42) and ground electrodes 45 (current-carrying portions 47).

As shown in FIG. 2, the electrode insertion holes 33 and 34 for the power electrodes are arranged in parallel facing each other at a predetermined interval, and the electrode insertion hole 35 for the ground electrode is arranged at an intermediate position below the electrode insertion holes 33 and 34. The arrangement of these three electrode insertion holes conforms to the same standard (for example, JIS C 8303 two-prong grounded outlet).
Note that FIG. 1 corresponds to the AA cross section in FIG. 2, shows only one side of the pair of power electrodes 40, and shows only one side of the power supply line 18 and a power supply line 88, which will be described later.

The frame 36 is further provided with an optical connector support portion 37 reaching the front plate 32 from its bottom wall.
The optical connector supporting portion 37 is provided with a slide hole 38 parallel to the inserting/removing direction of the ground electrode of the plug, and the slide hole 38 is aligned with the conductive portion 47 of the ground electrode 45 . For this reason, the side wall of the slide hole 38 is partially cut away so that the conducting portion 47 of the ground electrode 45 faces the inside of the slide hole 38 . Also, the slide hole 38 penetrates the bottom wall of the frame 36 .

An optical connector 50 is slidably inserted into the slide hole 38 of the optical connector support portion 37 . A guide pin 54 is provided on the side wall of the optical connector 50, and the guide pin 54 is guided by an elongated guide hole 39 formed in the side wall of the slide hole 38, so that the sliding range of the optical connector 50 is limited to a predetermined range. Further, the rotation of the optical connector 50 about its axis is restricted by the engagement of the guide pin 54 with the guide hole 39 .

The guide pin 54 penetrates the guide hole 39 and protrudes outside the side wall, and a tension spring 55 is provided between the tip of the guide pin 54 and the end of the optical connector support portion 37 on the side of the front plate 32 . As a result, the optical connector 50 is always urged toward the front plate 32, and one end of the optical connector 50 is positioned close to the conductive portion 47 of the ground electrode 45 in the free state.

FIG. 3 is an enlarged view of the optical connector 50. As shown in FIG.
The optical connector 50 comprises a main body 51 having a ferrule hole 56 extending through its axis and a cap 52 having a spring accommodating chamber 53. A guide pin 54 extends from the main body 51. As shown in FIG.
A ferrule 90 supported by a connecting block 92 is inserted into the ferrule hole 56 from the cap 52 side.

4A and 4B are enlarged views showing the connecting structure of the optical fiber 20 and the ferrule 90, where (a) is a longitudinal section and (b) is a BB section section in (a).
A two-core ferrule is used here. The coated optical fiber core 20a (two optical fiber strands) extending from the switchboard 10 is stripped, and the optical fiber strand 20b is inserted into a connecting block 92 coupled with a ferrule 90. An optical fiber 20c stripped of a protective member for the optical fiber strand 20b is embedded extending to the tip of the ferrule 90.

As is well known, the ferrule 90 is made of, for example, stainless steel (SUS) or zirconia ceramic, and its tip is polished so as to be perpendicular to its axial direction together with the end face of the optical fiber 20c.
In particular, as shown in FIG. 4(b), the cross section of the ferrule 90 has a partially cut semicircular shape.
In the present application, the optical fiber core 20a, the optical fiber strand 20b, and the optical fiber 20c in the optical fiber strand are collectively represented by "optical fiber" 20 unless otherwise specified.

Returning to FIG. 3, a concave portion 57 for slidably accommodating the connecting block 92 is formed in the cap 52 side end portion of the main body 51 .
The cap 52 is fixed to the other end of the main body 51 (the side farther from the conducting portion 47 of the ground electrode 45) by screwing or gluing, and the spring 58 disposed in the spring housing chamber 53 biases the connecting block 92 to press against the open end face of the ferrule hole 56 farther from the conducting portion 47.

Optical fiber 20 is connected to connecting block 92 and ferrule 90 through a hole provided in the bottom wall of cap 52 .
The ferrule hole 56 of the main body 51 of the optical connector 50 has a semicircular cross-section that matches the cross-sectional shape of the ferrule 90 . This defines the orientation of the ferrule 90 about the axis with respect to the main body 51 .
A slit 59 is formed in the end face of the main body 51 of the optical connector facing the front plate 32 to receive a protector portion, which will be described later.

Next, the male plug 60 provided at the end of the composite cable 86 extending from the personal computer 80 and inserted into the outlet 30 will be described.
The plug 60 is inserted into the outlet 30 to connect the power line 88 and the optical fiber 20' of the composite cable 86 to the power supply line 18 and the optical fiber 20 on the switchboard 10 side, respectively, and connect the ground line 89 of the composite cable 86 to the ground line 19.
The plug 60 consists of a cap plate 61 that fixedly supports the power electrode 65 and the ground electrode 70 by resin molding, and a case 62 that seals the opening with the cap plate.
The surface of the cap plate 61 is the surface facing the front plate 32 of the outlet 30 .

As shown in FIG. 5, the arrangement of the electrodes 65, 65, 70 corresponds to the electrode insertion holes 33, 34, 35 of the outlet 30, and is of the same standard as those on the market.
1, 5, and FIGS. 6 to 8 to be described later, the thickness of the ground electrode 70 is drawn large for easy understanding.

As shown in FIG. 1 , one end of the power electrode 65 extends vertically outward from the wall surface of the cap plate 61 and serves as a contact portion with the conducting portion 42 of the power electrode 40 of the outlet 30 . The other end of the power electrode 65 is connected to the power line 88 inside the case 62 .
A round hole 66 is provided near the tip of the contact portion of the power electrode 65 to engage with the bulging portion 43 formed in the current-carrying portion 42 of the power electrode 40 of the outlet 30 . The engagement relationship between the bulging portion 43 and the round hole 66 is a known structure, which enhances the function of preventing the plug 60 from coming off.
One end of the ground electrode 70 also extends vertically outward from the wall surface of the cap plate 61 and serves as a contact portion with the conducting portion 47 of the ground electrode 45 of the outlet. The other end of the ground electrode 70 is connected to the ground wire 89 inside the case 62 .

FIG. 6 is an enlarged view showing the ground electrode 70 taken out.
The ground electrode 70 has a tubular portion 71 having a bottom wall 72 at its outer tip, and a protector portion 78 extending outward from the tip of the tubular portion 71 (bottom wall 72).
The projection length of the cylindrical portion 71 from the cap plate 61 is set shorter than that of the power electrode 65 .
A connecting block 92' supporting a ferrule 90' is slidably accommodated in the tip side of the cylindrical portion 71, an inner cylinder 73 is inserted and fixed in the root side, and a spring 58' is arranged between the tip of the inner cylinder 73 and the connecting block 92'. The connecting block 92 ′ is biased by the spring 58 ′ and pressed against the bottom wall 72 of the inner cylinder 71 . A ferrule 90' extending from the connecting block 92' extends outwardly through a hole 75 in the bottom wall 72'.

Although not shown, the hole 75 in the bottom wall 72 has a shape that matches the cross section of the ferrule 90', thereby defining the orientation of the ferrule 90' in the direction around the axis. The orientation of the ferrule 90' is set so as to match the orientation of the ferrule 90 in the optical connector 50 of the outlet when the plug 60 is inserted into the outlet 30. FIG.
The shape and size of ferrule 90' and connecting block 92' are the same as those of ferrule 90 and connecting block 92 shown in FIG.

As shown in FIG. 6, the protector portion 78 surrounds a ferrule 90' protruding from the bottom wall 75 with a predetermined gap, and its outer peripheral surface is a portion of the outer peripheral surface of the cylindrical portion 71 that extends in the axial direction.
The area where the protector portion 78 surrounds the ferrule 90' is preferably a semicircle or more in cross section. Also, the length of the protector portion 78 is preferably equal to or slightly shorter than the maximum protruding length of the ferrule 90' when the connecting block 92' is pressed against the bottom wall 72. FIG.

The length of the cylindrical portion 71 protruding from the wall surface of the cap plate 61 is set so that a slight gap is formed between the bottom wall 75 of the cylindrical portion 71 and the end face of the optical connector 50 when the plug 60 is inserted into the outlet 30 and the cap plate 61 and the front plate 32 come into contact with each other. Also, the depth of the slit 59 of the optical connector 50 is set to such an extent that the protector portion 78 does not hit the bottom, but even if there is an error, it is similarly absorbed.

Returning to FIG. 1, the composite cable 86 from the personal computer 80 is led through the hole provided in the top of the case 62, and the power supply wire 88 and the ground wire 89 are connected to the roots (connections) of the power electrode 65 and the ground electrode 70 by caulking or the like as described above. The optical fiber 20' is also connected to the connecting block 92' (and ferrule 90') through the inner tube 73 of the ground electrode.
The connection structure between the optical fiber 20', the connecting block 92' and the ferrule 90' is the same as shown in FIG.

FIG. 7 shows a connection state in which the plug 60 is inserted into the outlet 30 in the above configuration.
The power electrode 65 of the plug 60 comes into contact with the conducting portion 42 of the power electrode 40 of the outlet 30 to be in a power conducting state, and the power supply line 18 and the power supply line 88 are connected.
The cylindrical portion 71 of the earth electrode 70 of the plug 60 is brought into contact with the conductive portion 47 of the earth electrode 45 of the outlet 30 to connect the earth wire 19 and the earth wire 89 .
Then, the ferrule 90' protruding from the tip of the tubular portion 71 enters the ferrule hole 56 of the optical connector 50 of the outlet, and the tip of the ferrule 90 comes into contact with the tip of the ferrule 90 housed in the ferrule hole.

At this time, since the orientations of the ferrules 90 and 90' in the axial direction are set to match each other, the two optical fibers on the end surfaces of the ferrules face each other with high accuracy. Thereby, the optical fiber 20 and the optical fiber 20' are connected.
During this time, the protector portion 78 that protects the ferrule 90' projecting from the tubular portion 71 is received in the slit 59 of the optical connector 50, so that it does not interfere with the optical connector 50. FIG.

FIG. 8 shows the state when a normal power plug is inserted into the outlet.
In a conventional plug 60Z, the ground electrode 70Z has a protruding length equivalent to that of the power electrode 65, but the power electrode 65 comes into contact with the conducting portion 42 of the power electrode 40 of the outlet 30 and enters a power conducting state, whereby the power supply line 18 and the power supply line 88 are connected. Also, the ground electrode 70Z of the plug 60Z is also in contact with the conducting portion 47 of the ground electrode 45 of the outlet, and the ground wire 19 and the ground wire 89 are connected.

On the other hand, since the length of the ground electrode 70Z is longer than the cylindrical portion 71 of the ground electrode 70 of the plug 60 in the embodiment, the tip of the ground electrode 70Z contacts the optical connector 50. FIG. Here, since the optical connector 50 is slidable along the slide hole 38, when pushed by the ground electrode 70Z of the plug 60Z, it escapes to the outside against the tension spring 55, and the ground electrode 70Z and the optical connector 50 do not interfere with each other.
As described above, the receptacle 30 can be plugged with a conventional general plug 60Z that is not compatible with optical fibers, and in this case also, a power supply state can be obtained as in the conventional case.

Next, the composite cable 86 will be explained.
As the composite cable 86, for example, those proposed in JP-A-2001-266665, JP-A-2001-318286, and others can be used.
That is, the composite cable 86 has a circular cross section as a whole, and an insulator 111 therein has three non-circular blocks 112 which are point-symmetrical with respect to the central axis O. As shown in FIG.

Each block 112 has an arcuate surface 113 on its outer circumference and an arcuate surface 114 that protrudes toward the central axis O on its inner circumference. The top of the arc-shaped surface 114 has a gap of a predetermined amount d from the central axis O, thereby forming a space S defined by each arc-shaped surface 114 between the three blocks 112 and having a shape in which the arms 115 are extended in three directions.
Corners of the outer circumference of the insulator 111 are chamfered on a radial line passing through the tip of each arm 115 from the central axis O to form a notch 118 in appearance, and the radial line connecting the tip of each arm 115 and the notch 118 is a dividing line 117 between the blocks 112.

The outer periphery of the block 112 is covered with a sheath 110 having a ring-shaped cross section, and an optical fiber 20' is arranged on the central axis O in the space S inside. In addition, spacers 125 are attached to the optical fiber at predetermined intervals in its longitudinal direction.
At the center of each block 112, a conductor 120 is arranged as a power line 88 and a ground line 89. FIG.
It should be noted that the position of the tip of each arm 115 described above is preferably such that it reaches the envelope 122 of each conductor 120 .
The sheath 110 and the insulator 111 are each made of polyvinyl chloride resin or the like.

The above configuration is realized, for example, by enclosing the optical fiber 20′ at the center and extruding each block 112 of the insulator 111 while enclosing the conductor 120 to form a single block, so that the blocks 112 are in contact with each other at the demarcation line 117, and then the outer periphery of the insulator 111 is covered with the sheath 110 by extrusion molding.
According to this composite cable 86, when the plug 60 is inserted into the receptacle 30 and the end faces of the ferrules 90, 90' are brought into contact with each other and slightly retracted against the springs 58, 58', the optical fibers connected to the ferrules can escape in a wide space, and the optical fibers 20' are not subjected to excessive external force.
Furthermore, even when an external force is applied to the cable from the lateral direction, such as being stepped on, the space S formed in the center of the interior exerts a so-called cushion function to protect the optical fiber.

Also, although it is not a recommended wiring process, even if the composite cable is too long and bundled in a bow-knot, the optical fiber 20' can escape from the position of the central axis O to the area of the arm 115, and no excessive external force is applied to the optical fiber.
Therefore, a tensile strength member for protecting the optical fiber, which is always required in conventional optical cables, is not required.
In addition, since the conductors 120 are arranged point-symmetrically around the central axis O, the connection between the plug 60 in which the power electrodes and the ground electrodes are arranged in the same manner is particularly smooth and easy.
Since the sheath 110 covers the outside of the block 112 here, it is not necessary to join the blocks 112 together. In this case as well, the division lines 117 between the blocks 112 of the insulator are short, and notches 118 are formed on the outer periphery on the division lines 117, so that the blocks 112 of the cable terminal become a composite electric wire that can be easily separated at the division lines 117 during wiring.
Although the composite cable 16 is based on VVF as described above, the same structure as the composite cable 86 may be adopted.

In this embodiment, the plug 60 corresponds to a male connector, and the outlet 30 corresponds to a female connector.
The spring 58' of the plug 60 constitutes the first biasing means, and the position of the ferrule 90' in which the connecting block 92' is pressed against the bottom wall 72 of the tubular portion 71 corresponds to the first predetermined position.
The position of the ferrule 90 in a state where the spring 58 of the socket 30 constitutes a second biasing means and the connecting block 92 is pressed against the open end face of the ferrule hole 56 of the optical connector 50 corresponds to the second predetermined position.
The third predetermined position corresponds to the position of the optical connector 50 in which the tension spring 55 of the socket 30 constitutes a third biasing means, the guide pin 54 is regulated by the guide hole 39, and the optical connector 50 is closest to the conductive portion 47 of the ground electrode.

This embodiment is configured as described above, and the outlet 30 and the plug 60 paired with each other have power electrodes 40, 65, ground electrodes 45, 70, and ferrules 90, 90' connected to the optical fibers 20, 20' and arranged coaxially with the ground electrodes 45, 70, respectively. Since they are opposed to each other, a simple operation of inserting the plug 60 into the outlet 30 simultaneously connects the power supply system and the optical fiber. Therefore, by combining the power supply line 88 and the like with the composite cable 86 in which the optical cable 20' is integrated, the wiring around the connecting portion can also be simplified.

In particular, the plug 60 has a power electrode 65 and a ground electrode 70 extending parallel to each other from a cap plate 61. The ground electrode 70 forms a cylindrical portion 71 having a bottom wall 72 on the tip side.

The outlet 30 also has conductive portions 42 and 47 in which a power electrode 40 and a ground electrode 45 contact a counterpart power electrode 65 and a ground electrode 70. An optical connector 50 having a ferrule hole 56 is provided on the back side of the ground electrode conductive portion 47. The ferrule hole 56 holds a ferrule 90 on the side away from the ground electrode conductive portion 47, and receives a mating ferrule 90' from an opening on the conductive portion 47 side. Since 42 and 47 correspond to the plug 60 and are arranged to meet the standard of a normal female plug, it is compatible with the conventional female plug.

Further, the ferrule 90' of the plug 60 is positioned at a position where the connecting block 92' is pressed against the bottom wall 72 of the cylindrical portion 71 while being biased in the outward projecting direction by the spring 58', but is slidable with respect to the cylindrical portion 71 of the ground electrode. Therefore, when the ferrule 90' receives an external force such as contact with the ferrule 90 of the outlet when the plug 60 is inserted into the outlet 30, it retreats in the axial direction against the spring 58', absorbs the external force, and maintains the surface pressure on the end face of the ferrule 90' at an appropriate level.

The ferrule 90 of the outlet 30 is also urged by the spring 58 toward the conductive portion 47 of the ground electrode, and the connecting block 92 is positioned at a position where it is pressed against the opening end face of the ferrule hole 56 of the optical connector 50 on the far side from the conductive portion 47 . The surface pressure between the end faces of the ferrules becomes a moderate level at a position where the urging forces applied to the ferrules 90 and 90' are balanced.

Since the ground electrode 70 of the plug 60 has a protector part 78 extending outward from the bottom wall 72 of the cylindrical part 71, even if the ferrule 90' protrudes from the cylindrical part 71, it is covered, and damage to the ferrule 90' is prevented even if another object collides with it. Since the outer shape of the protector portion 78 is within the cross section of the outer shape of the cylindrical portion 71, the function as the ground electrode is not impaired.

Further, the optical connector 50 of the outlet 30 is urged by the tension spring 55 so that one end thereof is set at a position close to the conducting portion 47 of the ground electrode 45, but is slidable in the axial direction. Therefore, even when the length of the ground electrode of the plug inserted into the outlet 30 interferes with the optical connector at the set position, the interference is prevented by sliding the optical connector 50 backward. This allows for variations in the length of the ground electrode of regular male plugs to still maintain compatibility.

The composite cable 86 is assumed to extend from the PC 80, but if the composite cable and the PC are to be detachable, the other end of the composite cable may be provided with a female-type plug 100 having a structure similar to that of the outlet 30 and having a structure similar to that of the outlet 30, as shown in FIG.
Similarly, in the embodiment, the female connector is the outlet 30 installed on the wall of a building or the like.

The optical fibers 20, 20' are aligned by matching the cross-sectional shape of the ferrule hole 56 with the cross-sectional shape of the ferrules 90, 90'. Alternatively, the cross-sectional shape of the connecting blocks 92, 92', which are integrally coupled with the ferrules 90, 90' to support the ferrules, may be square other than circular, and the cross-section of the sliding region of the connecting block may be matched to the cross-sectional shape of the connecting block. Regulating the posture enables highly accurate alignment.
Although an example using the two-core optical fibers 20 and 20' has been shown, the number of cores of the optical fibers may be set as required, and a ferrule corresponding to the number of cores may be used.
In particular, in the case of a single-core ferrule, by setting the optical fiber in the axial center of the ferrule, the cross section of the ferrule can be made circular without the need to regulate the posture.

The connection structure between each electrode, the power supply line, the power supply line and the ground line is not limited to the illustrated one, and any known structure can be adopted.
In addition, the arrangement and size of each power electrode and ground electrode on the male and female sides are based on the standards for plugs and outlets for commercial power sources, but if the standards are revised or the standards differ from country to country, they may be appropriately set to meet the standards in each region.
Although the protector portion 78 covers a portion of the periphery of the ferrule 90' protruding from the cylindrical portion 71 of the ground electrode 70, it may surround the entire periphery.

Furthermore, in the embodiment, the ferrule connected to the optical fiber on the plug side is supported by the ground electrode, but regardless of the presence or absence of the ground electrode, the ferrule may be supported by the power electrode instead of the ground electrode as long as the cross section of the power electrode can be cylindrical. It is also possible to assign a single core ferrule to each power electrode. In this case, the optical connector 50 on the outlet side is also arranged on the back side of the corresponding power electrode in the axial direction. In any case where the optical fiber is supported by any of the electrodes, the cross-sectional structure of the composite cable 86 is adopted so that the optical fiber is arranged on the central axis, so that it can be easily routed.

Further, by forming the ferrule on the plug side from a highly conductive metal material, the ferrule itself can also be used as a power electrode or a ground electrode.
In this case, the ferrule hole 56 of the optical connector 50 also has a large diameter corresponding to the ferrule on the plug side.
Furthermore, the optical connector 50 can also be used as a power electrode or a ground electrode.

In the embodiment, the combined power/optical connection structure by connecting the outlet 30 and the plug 60 is shown as an example in which the personal computer 80 is connected to the optical LAN HUB 14 provided on the switchboard 10. However, the optical LAN can be connected not only to the personal computer but also to a TV, a video device, and a DVD recorder for downloading high-definition video from the outside through a broadband router connected to an external optical fiber network. can be

Furthermore, it can be provided as a host-side adapter that can be connected to the outlet 30 via the plug 60 even when wireless communication is intervened in the connection between the HUB 14 and a notebook computer, for example.
FIG. 11 shows an example of connection between a host wireless adapter 93 as a host side adapter and a notebook computer 97 .
The host wireless adapter 93 comprises an optical LAN/USB protocol converter 94 and a wireless USB host 95 . The plug 60 described in the embodiment is connected to the host wireless adapter 93, the power supply line 88 and the ground line 89 are connected to a power supply unit (not shown) for driving the optical LAN/USB protocol converter 94 and the wireless USB host 95, and the optical fiber 20' is connected to the optical LAN/USB protocol converter 94.
