The bosses 50A and 50B are at positions shifted in the depth direction and the lateral width direction. The tip portions of the bosses 50A and 50B are at the same position in the thickness direction in the vertical direction (main body side casing 38).

  Of the two bosses 50A and 50B, one boss 50A has a boss body 52 formed in a cylindrical shape. On the other hand, the other boss 50 </ b> B has a boss body 52 formed in a cylindrical shape and a plurality of ribs 54 formed radially from the boss body 52. The boss body 52 is reinforced by these ribs 54.

  A bracket 56 of the hinge 46 is bridged between the bosses 50A and 50B and fixed with a fixing screw 58. The hinge 46 has a shaft member 60, and the bracket 56 supports the shaft member 60. The shaft member 60 is a columnar or cylindrical member whose longitudinal direction is the horizontal width direction of the notebook personal computer 32.

  On the other hand, the fixture 62 is fixed to the display-side casing 42. The fixture 62 supports the tubular member 64. The shaft member 60 is inserted into and supported by the cylindrical member 64. By the relative rotation of the cylindrical member 64 and the shaft member 60, the main body side casing 38 and the display side casing 42 rotate (rotate) relatively.

  As shown in FIGS. 2 to 5, the main body side housing 38 is provided with a USB board 68. A USB (Universal Serial Bus) connector (USB connector 66) is mounted on the USB board 68. The USB board 68 is an example of a connector board. The USB connector 66 is a connector into which a USB cable for connection with an external device is inserted, and is an example of a connection connector. As shown in FIG. 2, the USB board 68 and the control board 40 are electrically connected by a connection wiring 70.

  As shown in FIGS. 6 to 9, the USB board 68 is formed with an extending portion 74. The extending portion 74 has a shape that avoids contact with the bosses 50A and 50B and extends (disconnects) from the USB board 68 to between the bosses 50A and 50B. A portion extending through the bosses 50 </ b> A and 50 </ b> B is a mounting portion 76.

  On the other hand, in the extension part 74, the part between the USB board 68 and the mounting part 76 is a root part 78 that is the root of the extension part 74. The outer edge portion of the root portion 78 is a relief portion 82 having a shape curved inward so as to avoid the bosses 50A and 50B. The USB board 68 is also provided with a relief portion 84 having a curved shape so as to avoid the bosses 50A and 50B. The escape portion 82 and the escape portion 84 are smoothly continuous with a predetermined curvature.

  Here, in the extending part 74, the length in the direction orthogonal to the extending direction from the USB board 68 (arrow L1 direction) is defined as the width. As shown in FIGS. 6 and 8, the width W <b> 1 of the mounting portion 76 is wider than the width W <b> 2 of the root portion 78.

  As shown in FIGS. 7 and 9, a magnetic sensor 86 is mounted on the mounting portion 76 of the extending portion 74. That is, it can be said that the extending portion 74 is the sensor substrate 72 on which the magnetic sensor 86 is mounted. In other words, the sensor substrate 72 for mounting the magnetic sensor 86 has an extending portion 74 extending from the USB substrate 68, and the sensor substrate 72 is formed integrally with the USB substrate 68. The magnetic sensor 86 is mounted on the sensor substrate 72 and is positioned between the pair of bosses 50A and 50B. Even in a structure in which three or more bosses are formed, two of the three or more bosses are used as a pair of bosses 50A and 50B, and the magnetic sensor 86 is disposed between the pair of bosses. do it.

  The magnetic sensor 86 is a sensor that detects the strength of the magnetic field, and outputs an electrical signal corresponding to the strength of the magnetic field. A signal wiring 88 for flowing an electric signal of the magnetic sensor 86 is formed from the extending portion 74 (sensor substrate 72) to the USB substrate 68. The signal wiring 88 is connected to the control board 40 via the connection wiring 70.

  As shown in FIG. 5, a gap G <b> 1 in the height direction (arrow UP direction and the opposite direction) is generated between the wall member 48 and the bracket 56. The shape of the bracket 56 and the positions and heights of the bosses 50A and 50B are set so that the sensor substrate 72 (extending portion 74) is disposed in the gap G1, and the magnetic sensor 86 is positioned in the gap G1. The In other words, in this embodiment, the position and height of the boss 50 </ b> A are appropriately set to create a gap G <b> 1 between the wall member 48 and the bracket 56, so that the magnetic sensor 86 is attached to the main body side housing 38. It is possible to arrange it inside (gap G1).

  The bracket 56 is a part of the hinge 46. That is, it can be said that the gap G <b> 1 is generated between a part of the hinge 46 and the wall member 48. By disposing the magnetic sensor 86 in the gap G1, a structure in which the magnetic sensor 86 is disposed near the hinge 46 can be realized.

  As shown in FIGS. 6 and 8, a plurality of fixing holes 90 are formed in the USB substrate 68. The fixed hole 90 </ b> A that is one of the fixed holes 90 is formed in the vicinity of the boundary with the extending portion 74. A fixing claw 92 of the USB connector 66 is inserted into the fixing hole 90 and fixed by a fixing material such as solder.

  A predetermined width W3 (see FIG. 8) for forming the signal wiring 88 is secured between the relief portion 82 of the USB board 68 and the fixing hole 90A. In other words, the fixing hole 90 </ b> A and the escape portions 82 and 84 are formed close to each other while ensuring the width W <b> 3 to the extent that the signal wiring 88 is formed, and the signal wiring 88 is thinned.

  A plurality of signal holes 91 are further formed in the USB board 68. The signal pin of the USB connector 66 is inserted into the signal hole 91 and connected to the wiring of the USB board 68.

  As shown in FIG. 6, in the present embodiment, the signal wiring 88 is also formed between the plurality of signal holes 91 </ b> A in the USB substrate 68. That is, in the place where the signal wiring 88 is formed, the widths W4 and W5 for forming the signal wiring 88 are secured between the plurality of signal holes 91A. The widths W3, W4, and W5 are lengths in a direction orthogonal to the extending direction of the signal wiring 88.

  The signal wiring 88 can also be formed between the signal hole 91 and the edge of the USB board 68 (for example, the escape portion 84).

  As shown in FIG. 3, a magnet 94 is attached to the display-side housing 42. The position of the magnet 94 is a position facing the magnetic sensor 86 when the display-side casing 42 is in the closed state. That is, when the display-side housing 42 is in the closed state, the magnet 94 approaches the magnetic sensor 86. The magnet 94 moves away from the magnetic sensor 86 as the display-side housing 42 rotates from the closed state to the open state. As described above, the distance between the magnet 94 and the magnetic sensor 86 changes in accordance with the open / close state of the display-side casing 42, so that the strength of the magnetic field at the position of the magnetic sensor 86 also changes.

  Next, the operation of this embodiment will be described.

  In the notebook personal computer 32 of the present embodiment, as shown in FIGS. 1 to 3, the main body side casing 38 and the display side casing 42 are rotatably connected by a hinge 46. When the display-side housing 42 is in the closed state, the closed state can be detected by the magnetic sensor 86 as the magnet 94 approaches the magnetic sensor 86. When the display-side casing 42 is in the open state (the state shown in FIG. 1), the open state can be detected by separating the magnet 94 from the magnetic sensor 86.

  In the present embodiment, the magnetic sensor 86 is provided in the main body side housing 38. The main body side housing 38 is also a housing provided with a control board 40 (control unit). The signal wiring 88 for transmitting the electrical signal of the magnetic sensor 86 to the control board 40 does not pass through the hinge 46. For this reason, disconnection of the signal wiring (cable) can be suppressed as compared with the structure in which the cable for transmitting the electric signal of the magnetic sensor 86 to the control board 40 passes through the hinge 46.

  As shown in FIG. 5, in the present embodiment, the shape of the bracket 56 and the positions and heights of the bosses 50 </ b> A and 50 </ b> B are set so that a gap G <b> 1 is generated between the wall member 48 and the bracket 56. By generating the gap G1 in this way, it is possible to realize a structure in which the sensor substrate 72 is positioned in the gap G1 and the magnetic sensor 86 can be disposed inside the main body side housing 38.

  The magnetic sensor 86 may be structured to be attached to the main body side housing 38 using an attachment member or the like, for example. When the magnetic sensor 86 is provided on the sensor substrate 72 as in the present embodiment, the above-described mounting member is unnecessary. And since the structure which formed the signal wiring 88 in the sensor board | substrate 72 can be taken, the cable for outputting the electrical signal of the magnetic sensor 86 is unnecessary, and can reduce a number of parts.

  Although the sensor board 72 may be a separate body from the USB board 68, in the present embodiment, the sensor board 72 is integrated with the USB board 68, so the number of components is small compared to a structure that is a separate body. Further, as compared with a structure in which these are separate bodies, assembly to the main body side housing 38 is also easy.

  As a structure in which the sensor substrate 72 is formed integrally with the USB substrate 68, in this embodiment, the sensor substrate 72 has an extending portion 74 that extends from the USB substrate 68 to between the bosses 50A and 50B. Thus, the sensor substrate 72 can be formed with a simple structure in which a part of the USB substrate 68 is extended.

  The extending portion 74 has a root portion 78 and a mounting portion 76. An escape portion 82 is formed in the root portion 78. The shape of the extended portion 74 (sensor substrate 72) avoiding the bosses 50A and 50B can be realized by the escape portion 82. Then, by further extending the mounting portion 76 from the root portion 78, the magnetic sensor 86 can be mounted on the mounting portion 76 (between the bosses 50A and 50B).

  The width W 1 of the mounting portion 76 is wider than the width of the root portion 78. Therefore, a sufficient area for mounting the magnetic sensor 86 can be secured as the mounting portion 76.

  The signal wiring 88 of the magnetic sensor 86 is formed from the mounting portion 76 of the extending portion 74 to the root portion 78. That is, the signal wiring 88 can be formed by effectively using the extending portion 74 (sensor substrate 72), and a new member for providing the signal wiring is unnecessary.

  An escape portion 84 is also formed on the USB substrate 68. With a simple structure for forming the escape portion 84, a structure in which the USB board 68 avoids the bosses 50A and 50B can be realized.

  A fixing hole 90 is formed in the USB substrate 68. Since the fixing claw 92 of the USB connector 66 is inserted into the fixing hole 90, it is easy to align and fix the USB connector 66 to the USB board 68.

  In the USB board 68, a thin signal wiring 88 is formed between the escape portions 82 and 84 and the fixing hole 90. While securing the width W3 for forming the signal wiring 88 and the fixing hole 90 and the escape portions 82 and 84 are close to each other, the width of the sensor substrate 72 and the USB substrate 68 in the vicinity of the fixing hole 90 is excessive. Widening can be suppressed. As a result, the notebook personal computer 32 can be reduced in size.

In the USB board 68, signal wiring 88 is also formed between the plurality of signal holes 91A. The USB board 68 can be reduced in size by securing the signal holes 91A between the signal holes 91A while ensuring the widths W4 and W5 for forming the signal wirings 88. This can also contribute to the downsizing of the notebook personal computer 32.

  The signal wiring 88 may also be formed between the signal hole 91 and the edge of the USB board 68 (for example, the escape portion 84). Even in this structure, the signal hole 91 and the edge of the USB board 68 are brought close to each other while ensuring a width for forming the signal wiring 88 between the signal hole 91 and the edge of the USB board 68. Thus, the USB board 68 can be reduced in size.

  In the above description, the USB connector 66 is given as an example of the external connector, and the USB board 68 is given as an example of the connector board. However, examples of the external connector and the connector board are not limited to these. That is, the external connectors widely include connectors used for electrical connection with external devices. And as a connector board | substrate, what is necessary is just a board | substrate with which such a connector is provided.

  The folding information processing apparatus is not limited to the above-described notebook personal computer. For example, a foldable mobile phone, a product management terminal, an electronic dictionary, a video playback device, or the like may be used.

  The embodiments of the technology disclosed in the present application have been described above. However, the technology disclosed in the present application is not limited to the above, and can be variously modified and implemented in a range not departing from the gist of the present invention.
