Description

  This case relates to an electronic device such as a personal computer.

  Some electronic devices such as a personal computer display an apparatus state by an LED (Light Emitting Diode). The device status to be displayed includes, for example, a power-on state, access to an HDD (Hard Disk Drive) or ODD (Optical Disk Drive), and the like. In addition, examples of the device state in the case where the electronic device uses a charging battery include a required charging state in which the remaining amount of the battery is below a threshold, charging the charging battery, and the like.

  Conventionally, in the status display by the LED, a structure in which the light of the LED installed inside the apparatus is guided by a predetermined light guide member to a light emitting window provided on the side surface of the housing is often adopted (for example, (See Patent Document 1).

JP 2005-93188 A

  In the case where there are a plurality of device states to be displayed, a plurality of light emitting windows are often arranged side by side on the side surface of the housing for ease of securing an installation space, design requirements, and the like. In the apparatus, a plurality of LEDs are arranged side by side corresponding to the arrangement of the plurality of light emitting windows.

  Here, in recent years, in a small electronic device such as a notebook personal computer (notebook PC) or the like, due to a demand for further miniaturization, the arrangement interval of the light emitting windows as described above, and further, the arrangement interval of the LEDs is increased. It is expected to be shorter. As a result, there is a risk that light of a certain LED leaks from a light emitting window adjacent to the light emitting window corresponding to the LED.

  For this reason, there is a demand for a light-shielding structure that has a simple structure that can cope with downsizing and can also exhibit high light-shielding properties.

  In view of the above circumstances, an object of the present invention is to provide an electronic apparatus having a simple and highly light-shielding structure.

  A basic form of an electronic device that achieves the above object includes a plurality of light sources and a light guide member.

  The plurality of light sources are arranged at intervals from each other, each emitting light.

  The light guide member has a plurality of light guides, walls, and connecting portions.

  The plurality of light guides guide light emitted from the light source, which protrudes toward one of the plurality of light sources.

  The wall is located between the plurality of light guides, and is made of the same material as that of the light guide, and inhibits light transmission on the surface.

  The connecting portion is formed of the same material as that of the light guide, which is formed by integrally connecting the plurality of light guides and the wall.

  According to this case, an electronic device having a simple and highly light-shielding light-shielding structure can be obtained.

  Here, in the display device 100, the brightness of the image displayed on the display screen 101 a is automatically adjusted to the brightness according to the illuminance around the notebook PC 10. A light receiving window 102 that receives light around the notebook PC 10 in the display housing 110 is provided in the second surface portion 112 and incorporated as a part thereof. Further, the display housing 110 accommodates an illuminance sensor, which will be described later, for detecting the illuminance of incident light from the light receiving window 102 at a position behind the light receiving window 102.

  When the notebook PC 10 is in the open state, the main body device 200 is provided on the front side of the front and the rear with the display screen 101a as a boundary with respect to the display device 100.

The sub screen 205 also serves as an input operation surface for detecting an input operation corresponding thereto. And the inclined surface 211b has the accommodating part 207 of the operation pen 206 used for said contact operation in a part of the inclined surface 211b. For example, if the input operation surface of the sub-screen 205 is a device that detects contact with the input operation surface, the operation pen 206 may be a simple rod-shaped plastic body. Further, even when the input operation surface of the sub screen 205 is an infrared type, the operation pen 206 may be the same plastic body. On the other hand, if the input operation surface of the sub screen 205 is an electromagnetic induction type detection device, an electronic pen may be used as the operation pen 206. That is, the operation pen 206 which is an example of the operation body may be appropriately changed according to the type of the input operation surface of the sub screen 205.

  In addition, two speakers 208 are installed on the inclined surface 211b with the sub screen 205 interposed therebetween, and various operation buttons 209 and a camera 221 are provided on the right side of the sub screen 205 in the drawing.

The slope exhaust port 224 and the rear exhaust port 225 are provided side by side on the outer surface of the main body housing 210. Further, each intake port and exhaust port are partitioned into a plurality of openings by a plurality of ribs.

  The notebook PC 10 of this embodiment has the appearance described with reference to FIGS.

  Next, the peripheral structure of the light receiving window 102 provided in the display device 100 will be described in detail.

  FIG. 5 is a cross-sectional view of the notebook PC taken along the cutting line CC in FIG. FIG. 6 is an enlarged cross-sectional view of an area D surrounded by a square in FIG.

  In FIG. 5, the internal structure of the main body device 200 that is not related to the peripheral structure of the light receiving window 102 is not illustrated, and in FIG. 6, the main body device 200 itself is not illustrated.

  As described above, the light receiving window 102 is located below the display screen 101a and is incorporated as a part of the second surface portion 112 that is inclined downward from the direction of the normal line E of the display screen 101a. ing.

  As can be seen from the enlarged sectional view of FIG. 6, the light receiving window 102 is a part of the surface of the following window component 103. The window component 103 is a component fitted into the opening of the second surface portion 112 opened at the following position.

  The display screen 101a is exposed from the display housing 110 by surrounding the first surface portion 111 with a frame shape. That is, the first surface portion 111 is the outer surface of the display housing 110 at the edge of the portion where the display screen 101a is exposed. The opening into which the window part 103 is fitted is opened at a position closer to the back side than the outer surface (that is, the first surface portion 111) at the edge in the second surface portion 112.

  A sensor substrate 105 on which an illuminance sensor 104 that detects the illuminance of incident light from the light receiving window 102 is mounted on the inner wall 113 on the back side of the display housing 110 is fixed. Yes. The inner wall surface 113 on the back side is a surface substantially parallel to the display screen 101a. For this reason, the normal line E ′ of the light receiving surface in the illuminance sensor 104 is directed in substantially the same direction as the normal line E of the display screen 101 a. In addition, a plurality of shielding ribs 106 are arranged around the sensor substrate 105 so that light from the liquid crystal panel 101 does not enter the periphery of the illuminance sensor 104.

  FIG. 7 is a perspective view showing the window part in detail.

  Part (A) of FIG. 7 shows an external perspective view of the window part 103, and part (B) shows a perspective perspective view of the window part 103.

  The window part 103 has a flange 103a for fixing to the display housing 110, and a protrusion 103b that is fitted into the opening of the second surface portion 112 and exposed to the outside.

  Then, of the rear surface of the protruding portion 103b with respect to the surface exposed to the outside (the light receiving window 102), the portion facing the illuminance sensor 104 in FIG. 6 is directed to the illuminance sensor 104 with the protruding portion 103b fitted in the opening. A light guide 103c described later extends in the direction.

  In the present embodiment, since the light receiving window 102 is incorporated as a part of the second surface portion 112, the light receiving window 102 is inclined downward from the direction of the normal line E of the display screen 101a. Yes. That is, the normal F of the light receiving window 102 is shifted downward by the deviation angle θ with respect to the normal E of the display screen 101a. For this reason, the light receiving window 102 receives the incident light from the direction centered on the direction shifted by the deviation angle θ with respect to the normal E of the display screen 101a into the display housing 110.

  On the other hand, the normal E ′ of the light receiving surface in the illuminance sensor 104 is directed in substantially the same direction as the normal E of the display screen 101a. In order for the illuminance sensor 104 to accurately detect illuminance, it is desirable that light be incident on the light receiving surface of the illuminance sensor 104 along the normal E ′ of the light receiving surface. Therefore, the light guide 103c plays a role of aligning the direction of incident light from the incident range centered on the shifted direction as described above in a direction along the normal line E ′ of the light receiving surface of the illuminance sensor 104. I'm in charge. The light guide 103c guides the incident light thus aligned to the illuminance sensor 104.

  The light guide 103c is located near the illuminance sensor 104 in a direction along the normal line of the light receiving surface of the illuminance sensor 104 from a position facing the illuminance sensor 104 in FIG. 6 with the protrusion 103b fitted in the opening. It extends in a cylindrical shape for a length sufficient to reach it.

  The window part 103 described above is integrally formed of a colorless and transparent resin material.

  Then, a black screen 103d in which a portion corresponding to the base of the light guide 103c is cut out in a circular shape is provided by printing on a surface (light receiving window 102) exposed to the outside of the protruding portion 103b. For this reason, the incident range of incident light is limited to the circular hole of the black screen 103d. The incident light passing through the hole is guided to the light receiving surface of the illuminance sensor 104 along the normal line E ′ of the light receiving surface by the light guide 103c.

  Here, a first comparative example for comparison with the present embodiment will be described.

  The notebook PC of the first comparative example is different from the notebook PC 10 of the present embodiment in the mounting position of the light receiving window and the illuminance sensor, and the shape around the light receiving window in the display housing.

  FIG. 8 is a schematic diagram showing the notebook PC of the first comparative example.

  In FIG. 8, the same components as those of the notebook PC 10 of the present embodiment shown in FIG. 1 and the like are denoted by the same reference numerals as those in FIG.

  In the display device 500 of the notebook PC 50 of the first comparative example, the light receiving window 501 and the illuminance sensor 502 are located above the display screen 101a. Furthermore, the entire front surface of the display housing 510 is a flat surface along the display screen 101a, and the light receiving window 501 is incorporated as a part of the front surface. That is, in the notebook PC 50 of the first comparative example, the light receiving window 501 is directed in substantially the same direction as the normal line of the display screen 101a. In addition, the illuminance sensor 502 is fixed to a position on the back side of the light receiving window 501 on the inner wall surface on the back side of the display housing 510, similarly to the illuminance sensor 104 of the present embodiment, except for the mounting position.

  In the notebook PC 50 of the first comparative example having such a structure, in addition to the light from the direction in which the user views the display screen, the light receiving window 501 includes direct light and reflected light from the ceiling illumination UL, and from the display screen 101a. A lot of diffracted light enters. As a result, the illuminance sensor 502 tends to detect an illuminance higher than the illuminance that should be detected. In such a case, the brightness of the display image is not adapted to the surrounding illuminance, and the display image is difficult for the user to see.

  In contrast to the first comparative example described above, in the notebook PC 10 of the present embodiment, the light receiving window 102 is arranged closer to the back side than the surface of the display housing 110 at the edge where the display screen 101a is exposed. Yes. Furthermore, the detection range in which the illuminance sensor 104 detects the illuminance of light by the inclination of the light receiving window 102 as described above is a range in which the center is downward from the direction of the normal line E of the display screen 101a. . As a result, the incidence of light from the ceiling illumination UL and the display screen 101a is suppressed, and the illuminance sensor 104 detects the illuminance of light mainly from the direction in which the user views the display screen 101a. For this reason, the illuminance detected by the illuminance sensor 104 is the illuminance that should be detected. Thereby, in the notebook PC 10 of the present embodiment, the display image is displayed on the display device 100 with appropriate brightness.

  Further, in the present embodiment, the front surface of the display housing has a second surface portion 112 that is inclined downward from the direction of the normal E and the lower end reaches the back side of the display screen 101a. The light receiving window 102 is incorporated as a part of the second surface portion 112 thereof. In the present embodiment, the light receiving window 102 is tilted by this structure, and incidence of light from the ceiling illumination UL and the display screen 101a to the light receiving window 102 is effectively suppressed.

  In the present embodiment, since the light receiving window 102 is provided below the display screen 101a, the incidence of light from the ceiling illumination UL and the display screen 101a to the light receiving window 102 is more effectively suppressed. Yes.

Furthermore, in this embodiment, the black screen 103d provided in the light receiving window 102 limits the incident range of incident light to the circular hole of the black screen 103d. As a result, the incidence of light from the ceiling illumination UL or the display screen 101a to the light receiving window 102 is further effectively suppressed. In the present embodiment, the light receiving window 102 that is inclined as described above receives the light. The incident light is guided to the illuminance sensor 104 by the light guide 103c. By this light guide 103c, incident light is incident on the light receiving surface in a desired direction along the normal line of the light receiving surface of the illuminance sensor 104, so that the illuminance sensor 104 detects the illuminance with high accuracy. ing.

  In the present embodiment, the light receiving window 102 is incorporated in a second surface portion 112 that is inclined with respect to the first surface portion. However, the installation of the light receiving window 102 is not limited to this form, and may be another example as follows.

  FIG. 9 is a diagram showing another example of installation of the light receiving window.

  In this other example, the periphery of the position where the light receiving window 102 is installed is locally closer to the back side than the surface of the display housing 110 at the edge of the exposed portion of the display screen 101a to form a recess. A light receiving window 102 is incorporated in the bottom surface portion 112 ′ of the recess.

  Even in such another example, the effect of suppressing the light from the ceiling illumination UL and the display screen 101a can be obtained as in the present embodiment.

  In this embodiment, the relative positional relationship between the light receiving window 102 and the light receiving surface of the illuminance sensor 104 is a positional relationship in which the directions of the normals F and E ′ are shifted from each other by a deviation angle θ. This deviation is corrected by the light guide 103c. However, the relative positional relationship between the light receiving window 102 and the light receiving surface of the illuminance sensor 104 is not limited to this form, and may be another example as follows.

  FIG. 10 is a diagram illustrating another example of the relative positional relationship between the light receiving window and the light receiving surface of the illuminance sensor. FIG. 11 is a diagram showing still another example of the relative positional relationship between the light receiving window and the light receiving surface of the illuminance sensor.

  10 and 11 show two types of different examples in which the illuminance sensor is attached differently with respect to the cross section along the cutting line GG in FIG.

  In both of these two types of examples, the light receiving window 102 and the light receiving surface of the illuminance sensor 104 'are substantially parallel to each other. Then, the direction of the normal line F ′ of the substantially parallel planes is shifted downward by the deviation angle θ with respect to the direction of the normal line E of the display screen 101 a. In these other examples, the incident light incident along the normal F ′ of the light receiving window 102 travels without being bent in the light guide portion 103 c and enters the light receiving surface of the illuminance sensor 104 ′. Since the light receiving window 102 and the light receiving surface of the illuminance sensor 104 ′ are substantially parallel to each other, the incident direction on the light receiving surface is the desired incident direction along the normal line of the light receiving surface as it is.

  In another example of FIG. 10, the sensor substrate 105 ′ on which the illuminance sensor 104 ′ is mounted is fixed in an inclined state on the inner wall surface 113 of the display housing 110. The inclination of the sensor substrate 105 ′ at this time is such that the direction of the normal line of the light receiving surface of the illuminance sensor 104 ′ on the sensor substrate 105 ′ substantially coincides with the direction of the normal line F ′ of the light receiving window 102. .

  On the other hand, in another example of FIG. 11, the sensor substrate 105 ″ is fixed along the inner wall surface 113 of the display housing 110. Instead, the illuminance sensor 104 ′ is mounted in a state inclined to the sensor substrate 105 ″. Has been. The inclination of the illuminance sensor 104 ′ is such that the direction of the normal line of the light receiving surface of the illuminance sensor 104 ′ substantially coincides with the direction of the normal line F ′ of the light receiving window 102.

  As described above, in the other examples described with reference to FIGS. 10 and 11, it goes without saying that the display image is displayed with appropriate brightness, as in the present embodiment.

  In this embodiment, the black screen 103d is provided in the light receiving window 102. However, if the light receiving window 102 is sufficiently small, the black screen 103d may be unnecessary.

  Moreover, although the window part 103 is used in this embodiment, you may make it implement | achieve the same effect without using this. For example, without using the window part 103, the illuminance with the light receiving surface facing downward so that the normal of the light receiving surface of the illuminance sensor 104 (the center of the detection range) is downward with respect to the normal E ′ of the display screen 101a The sensor 104 or the sensor substrate 105 may be mounted on the display housing 110.

  In this embodiment, the display device 100 of the notebook PC 10 is illustrated as an example of the display device. However, the display device having the light receiving window and the illuminance sensor as described above is not limited to the display device 100 of the notebook PC 10. Absent. Such a display device may be, for example, a display device used in a desktop personal computer, a general television receiver, or the like.

  Next, the peripheral structure of the sub screen 205 shown in FIG. 1 will be described.

  The sub screen 205 is a display screen of a liquid crystal panel, similar to the display screen 101a, and displays the following auxiliary information as an image. Examples of the auxiliary information include icon information that cannot be displayed on the display screen 101a and instruction information such as enlargement / reduction or movement of the image displayed on the display screen 101a. The information processing circuit of the main device 200 generates such auxiliary information in addition to the information displayed on the display screen 101a and the like. In the present embodiment, by providing such a sub-screen 205, it is possible to easily view the display screen 101a and to operate the displayed image information.

  As described above, the sub screen 205 also serves as an input operation surface on which information is input by a contact operation with the operation pen 206.

  In the present embodiment, the sub screen 205 is incorporated as a part of an inclined surface 211b inclined forward with respect to the basic plane 211a.

  Here, before proceeding with the description of the peripheral structure of the sub screen 205 in the present embodiment, a second comparative example for comparison with the present embodiment will be described.

  The notebook PC of the second comparative example is different from the notebook PC 10 of the present embodiment in that the sub screen is incorporated.

  FIG. 12 is a schematic diagram showing a notebook PC of a second comparative example.

  In FIG. 12, the same components as those of the notebook PC 10 of the present embodiment shown in FIG. 1 and the like are indicated by the same reference numerals as those in FIG.

  In the notebook PC 60 of the second comparative example, the upper surface 601 of the main body device 600 is a surface along the same plane almost entirely. The sub screen 602 is incorporated as a part of the upper surface 601 on the display housing 100 side of the upper surface 601.

  Here, in general, a notebook PC is used with a main unit placed horizontally. Therefore, in the notebook PC 60 of the second comparative example, the user views the sub screen 602 from a shallow angle. Although the sub screen 602 is a display screen of a liquid crystal panel, if the angle at which the user views the sub screen 602 is shallow as described above, the sub screen 602 tends to deviate from the viewing angle of the liquid crystal panel. As a result, in the notebook PC 60 of the second comparative example, the visibility of the sub screen 602 tends to be low.

  In contrast to the second comparative example described above, in the notebook PC 10 of the present embodiment, the sub screen 205 is inclined forward with respect to the basic plane 211a. For this reason, the angle at which the user views the sub screen 205 becomes deeper than in the second comparative example. As a result, the angle at which the user views the sub screen 205 is unlikely to deviate from the viewing angle of the sub screen 205.

  In the present embodiment, since the angle at which the user views the sub screen 205 is difficult to deviate from the viewing angle, a general liquid crystal panel having a standard viewing angle is employed as the sub screen 205.

  In the present embodiment, the inclination of the sub screen 205 as described above is realized by a simple configuration in which the sub screen 205 is incorporated as a part of the inclined surface 211b.

  In the present embodiment, various components and the like are provided on the inclined surface 211b adjacent to the sub screen 205 as described above.

  FIG. 13 is an enlarged view of an inclined surface adjacent to the sub screen.

  As shown in FIG. 1 and FIG. 13, the inclined surface 211b is provided with the speaker 208, various operation buttons 209, and the camera 221 as described above on the inclined surface 211b adjacent to the sub screen 205. Yes.

  Since the speaker 208 is provided on the inclined surface 211b inclined to the user side, in this embodiment, the sound of the speaker 208 is easily directed to the user side, and the user can easily hear the sound. In addition, since various operation buttons 209 are provided on the inclined surface 211b, the operability of these operation buttons 209 is improved. In addition, the camera 221 also makes it easy for a user's face or the like to be captured to enter the angle of view.

  Here, as described above, the inclined surface 211b is oriented in a direction inclined forward with respect to the orientation of the basic plane 211a. The front end 211b_1 of the inclined surface 211b is located on the inner side of the main body device 200 with respect to the basic plane 211a. A recess formed by positioning the front end 211b_1 on the inner side of the main body device 200 is used as the storage unit 207 of the operation pen 206. As a result, the operation pen 206 is housed in a place that is easily visible to the user.

  On the other hand, in the present embodiment, the basic plane 211a is used as an installation place of the keyboard 201, and the keyboard 201 is attached along the basic plane 211a. The arrangement of the keyboard 201 and the inclination of the sub screen 205 as described above allow the user to see the sub screen 205 with good visibility while operating the keyboard 201.

  The storage unit 207 is provided so that the operation pen 206 does not interfere with the display device 100 even when the notebook PC 10 is closed with the operation pen 206 stored.

  FIG. 14 is a cross-sectional view taken along the cutting line HH in FIG. 2 around the storage portion of the operation pen in a state where the notebook PC is closed.

  As shown in the sectional view of FIG. 14, even when the notebook PC 10 is closed, there is a gap between the front end portion 211b_1 of the inclined surface 211b located on the inner side of the main body device 200 and the display device 100. Exists. The storage unit 207 is provided in the gap, and the operation pen 206 is stored in the storage unit 207 without interfering with the display device 100.

  In this embodiment, in order to effectively utilize the gap between the front end portion 211b_1 of the inclined surface 211b located on the inner side of the main body device 200 and the display device 100, the storage portion 207 is provided in this gap. Although it is provided, the storage portion 207 is not necessarily provided.

  Further, as shown in the cross-sectional view of FIG. 14 and the perspective view of FIG. 13, in this embodiment, the rear end portion 211b_2 of the inclined surface 211b is located on the outer side of the main body device 200 with respect to the basic plane 211a. ing.

  Here, in the present embodiment, as described above, the second surface portion 112 of the display device 100 is an inclined surface whose lower end reaches the back side of the display screen 101a. As a result, the display device 100 has a dent. When the notebook PC 10 is closed, the end 211b_2 on the rear side of the inclined surface 211b located on the outside of the main body device 200 enters the above-described dent in the display device 100 as described above. Thereby, the increase in the thickness direction in the main body device 200 by providing the inclined surface 211b as described above is shared by the display device 100. As a result, the increase in the thickness direction is suppressed in the entire notebook PC 10.

  As shown in the perspective view of FIG. 13, in the present embodiment, a plurality of inclined side surface intake ports 226 are provided on the side surface connected to the rear end portion 211 b </ b> _ <b> 2 of the inclined surface 211 b located outside the main body device 200. ing. Further, in the present embodiment, a plurality of inclined side surface intake ports 226 are similarly provided not only on the side surface of the right inclined surface 211b in FIG. 13 but also on the left side surface.

  Furthermore, in the present embodiment, the following plurality of inclined back surface intake ports are also provided on the back surface connected to the rear end portion 211b_2 of the inclined surface 211b.

  FIG. 15 is a perspective view of the main unit shown with the display device removed and a plurality of inclined rear intakes visible. FIG. 16 is a perspective view showing the notebook PC in a state where a plurality of inclined rear intake ports are hidden by the display device. FIG. 17 is a cross-sectional view taken along the section line JJ in FIG.

  As shown in FIG. 15, the plurality of inclined rear surface intake ports 227 are arranged on the rear surface connected to the rear end portion 211b_2 of the inclined surface 211b. As shown in FIG. 16, these inclined rear air inlets 227 appear to be hidden by the display device 100 in appearance when the notebook PC 10 is opened. However, as illustrated in FIG. 17, there is a gap between the display device 100 and the back surface connected to the rear end portion 211b_2 of the inclined surface 211b. Then, the air that has passed through the gap is taken into the main body housing 220 from the inclined back surface intake port 227.

  As described above, in this embodiment, in addition to the intake ports 222 and 223 shown in FIG. 4, the inclined side surface intake port 226 and the inclined rear surface intake port 227 using the protrusion of the rear end 211b_2 of the inclined surface 211b Is provided. Thereby, the cooling efficiency inside the main body housing | casing 220 is improved.

  In the present embodiment, the opening provided in the space generated by the inclined surface 221b is used as an intake port (inclined side intake port 226, inclined back intake port 227), but may be used as an exhaust port.

  In the present embodiment, the inclined side intake port 226 and the inclined rear intake port 227 are provided in order to effectively use the space generated by the inclined surface 221b, but this is not always necessary.

  In the present embodiment, the main device 200 of the notebook PC 10 is illustrated as an example of the electronic device having the sub screen as described above. However, the electronic device as described above is limited to the main device 200 of the notebook PC 10. is not. Such an electronic device may be, for example, a personal computer or the like that is separate from the display device and that the user operates while viewing a display image on the display device.

  In the present embodiment, the light receiving window 102 described above is provided in the display device 100. This is to prevent light from entering the light receiving window 102 from the ceiling illumination UL or the display screen 101a as described above. However, if the influence of such light entry is not taken into consideration, it is conceivable to use the inclined surface 211b in the main body device 200 as the installation location of the light receiving window 102.

  FIG. 18 is a diagram illustrating an example in which an inclined surface in the main body device is used as the installation location of the light receiving window.

  In the example of FIG. 18, the inclined surface 211 b adjacent to the sub screen 205 on the right side in the drawing is used as the installation location of the light receiving window 102 ′. In this example, an illuminance sensor (not shown) is arranged in the main body device 200 on the back side of the light receiving window 102 ′.

Next, the periphery of a plurality of light emitting windows provided in an area B surrounded by a dotted line in FIG. 1 on the front surface 212 of the main body housing 210, which displays the state of the notebook PC 10 with the light emitted from the LEDs in the apparatus. The structure will be described in detail.

  FIG. 19 is an enlarged view of an area B surrounded by a dotted line in FIG.

  As shown in FIG. 19, in the present embodiment, four types of light emitting windows 228 are provided on the front side surface of the main body casing 210. Further, the state of each type of light emission window 228 representing the notebook PC 10 is determined by the shape of the light emission window 228 that is lit.

  Next, an internal structure around the light emitting window 228 in the main body device 200 will be described.

  FIG. 20 is a perspective view showing the internal structure around the light emitting window. FIG. 21 is a plan view showing the internal structure around the light emitting window.

  Inside the main body device 200, an LED substrate 231 on which four LEDs 229 are arranged with a space between each other is mounted with the mounting surface of the LEDs 229 facing the outside of the device.

  The main body device 200 is provided with a light guide member 240 for guiding the light emitted from the LED 229 to the light emission window 228.

  FIG. 22 is a perspective view of the light guide member alone viewed from the LED substrate side.

  In the light guide member 240, four light guide bodies 241 and three light shielding walls 242 also shown in FIGS.

  Part (A) of FIG. 22 shows a perspective view in which the four light guides 241 and the three light shielding walls 242 in the light guide member 240 can be seen as a whole.

  The light guide 241 protrudes toward each LED 229 and guides light emitted from the LED 229 in the protruding direction. The light shielding wall 242 is located between the four light guides 241 and inhibits light transmission on the surface facing the light guide 241. And the connection part 243 has connected the four light guides 241 and the three light-shielding walls 242 which were located in a line with each other. In the present embodiment, the light guide member 240 is obtained by integrally forming the connection portion 243, the four light guides 241 arranged in a row, and the three light shielding walls 242 with a resin material or the like. That is, the light shielding wall 242 and the connection portion 243 are formed of the same material as that of the light guide 241.

  In the present embodiment, the light guide member 240 also serves as a front side wall in the main body casing 210. Further, the wall surface of the light guide member 240 corresponding to the outer surface of the main body casing 210 is plated. And the plating of the location where the light guide 241 guides the light is extracted in the shape of each light emitting window 228. As a result, light emitted from each LED 229 is guided to each light emitting window 228, and the light emitting window 228 emits light to the outside of the main body casing 210.

  Moreover, in this embodiment, the surface which faces the light guide 241 of each light shielding wall 242 which the light guide member 240 has is a rough surface of the grade which inhibits permeation | transmission of light.

  Part (B) of FIG. 22 shows an enlarged view of the light shielding wall 242 whose surface is a rough surface 242_1.

  The rough surface 242_1 suppresses leakage of light from a certain LED 229 to the light guide 241 and the light emission window 228 adjacent to the light guide 241 and the light emission window 228 corresponding to the LED 229.

  Here, a third comparative example for comparison with this embodiment will be described.

  In addition, about this 3rd comparative example, the description which paid its attention only to the periphery structure of the light emission window in a main body apparatus is given.

  FIG. 23 is a perspective view showing a light emitting window in the third comparative example. FIG. 24 is a perspective view showing the internal structure around the light emitting window in the third comparative example. FIG. 25 is a plan view showing the internal structure around the light emitting window in the third comparative example.

  In the notebook PC 70 of the third comparative example, four light emitting windows 701 are provided in the vicinity of the right corner of the main unit 700 on the front side in the drawing.

  In the vicinity of the light emitting window 701 in the main unit 700, an LED board 703 on which four LEDs 702 are arranged with a space therebetween is installed with the mounting surface of the LEDs 702 facing the outside of the apparatus. ing.

  The main unit 700 is provided with a light guide member 710 for guiding the light emitted from the LED 702 to the light emission window 703.

  FIG. 26 is a perspective view in which the light guide member is easily seen by removing the LED substrate.

  The light guide member 710 is formed by integrating four light guides 711 shown in FIGS. 24 and 25 by a connection portion 712. The light guide body 711 protrudes toward each LED 702 and guides light emitted from the LED 702 in the protruding direction. And the connection part 712 is formed with the same material as the material of the light guide 711 which connected the four light guides 711 mutually and united.

  Here, in the notebook PC 70 of this comparative example, in order to suppress leakage of light from a certain LED 702 to the light guide 711 and the light emission window 701 adjacent to the light guide 711 and the light emission window 701 corresponding to the LED 702. The light shielding wall 704 protrudes from the bottom surface of the main body housing 720. In this comparative example, the structure is complicated because the light guide 711 and the light shielding wall 704 are separate bodies. For this reason, due to manufacturing errors or the like, the relative alignment between the light guide 711 and the light shielding wall 704 is not good at the time of manufacturing, and a situation in which the above light leakage cannot be suppressed occurs. There is a fear. Furthermore, since the light guide 711 and the light shielding wall 704 are intricate, it is difficult to cope with a future request for space saving.

  In contrast to the third comparative example described above, in the notebook PC 10 of the present embodiment, the light guide 241 and the light shielding wall 242 are integrally connected as the light guide member 240 by the connecting portion 243. According to this structure, the relative alignment between the light guide body 241 and the light shielding wall 242 at the time of manufacture is higher than that in the third comparative example in which the light guide body 711 and the light shielding wall 704 are separate. Much easier. As a result, light leakage as described above can be reliably suppressed. Moreover, in this embodiment, the internal structure by the side of the front surface 212 of the main body apparatus 200 is simplified by employ | adopting the above light guide members 240. FIG. This makes it easier to meet future demands for space saving.

  In the present embodiment, the light guide member 240 also serves as a front side wall in the main body casing 210 as described above. Thereby, the number of parts of the main body casing 210 is reduced, and the manufacturing cost is reduced. Furthermore, in the present embodiment, each light emitting window 228 is formed by removing the plating at the location where the light guides 241 guide light. This also reduces the number of parts of the main body casing 210 and reduces the manufacturing cost associated with the reduction.

  In the present embodiment, the surface of the light shielding wall 242 is a rough surface 242_1 that inhibits the transmission of light, so that light leakage is suppressed. The formation of the rough surface 242_1 can be performed simultaneously with the formation of the light guide member 240 itself, for example, by forming the rough surface into a mold when the light guide member 240 is integrally formed of a resin material. In this embodiment, the manufacturing cost is also reduced in this respect.

  Here, as a method of suppressing light leakage by the light shielding wall 242, a method of plating the surface of the light shielding wall 242 facing the light guide 241 is also conceivable in addition to the method using the rough surface 242_1.

  Part (C) of FIG. 22 shows an enlarged view of another example of the light shielding wall 242 ′ whose surface is plated with 242 ′ _ 1.

  Another example of the light shielding wall 242 'provided with the plating 242'_1 has a high light shielding property and can more reliably inhibit light transmission.

  Further, as a method for suppressing light leakage, a method of applying a paint that inhibits light transmission to the surface of the light shielding wall 242 facing the light guide 241 is also conceivable.

  Part (D) of FIG. 22 shows an enlarged view of another example of the light shielding wall 242 ″ having the surface coated with the coating material 242 ″ _1 as described above.

  The application of the paint 242 ″ _1 leads to a reduction in manufacturing cost because it is easy to process. Also, in another example of the light shielding wall 242 ″, the application range of the paint 242 ″ _1 can be arbitrarily set, or after the application Can be modified.

  In the present embodiment, the main device 200 of the notebook PC 10 is illustrated as an example of the electronic device including the light guide member as described above. However, the electronic device as described above is limited to the main device 200 of the notebook PC 10. It is not a thing. Such an electronic device may be, for example, a desktop personal computer, a general electronic device provided with a display mechanism using LED emission, or the like.

  In this embodiment, the user can understand the operation state of the notebook PC 10 by the shape of the light emitting window 228 to be lit. However, the light emitting window 228 has the same shape, and the light emission color of the LED corresponding to the light emitting window 228 is the same. You may make it implement | achieve by changing.

  Next, the slope exhaust port 224 and the rear exhaust port 225 shown in FIG. 4 in the main body casing 210 will be described in detail.

  27 is an enlarged view of the slope exhaust port and the rear exhaust port shown in FIG.

  As described above, in the present embodiment, the slope exhaust port 224 is provided on the slope facing the rear face 214 from the second bottom face portion 213b located on the outer side of the main body casing 210 in order to secure a storage space for a radiator or the like. ing. A rear exhaust port 225 is provided on the rear surface 214. The two types of exhaust ports 224 and 225 are provided side by side on the outer surface of the main body casing 210.

  Here, the slope exhaust port 224 is partitioned into a plurality of openings by the following first ribs 224a in order to suppress a decrease in strength of the main body casing 210.

  28 is a cross-sectional view taken along the cutting line KK in FIG. 27 passing through the first rib, in the vicinity of the slope exhaust port.

  In FIG. 28, the fan 251 that generates wind in the main body casing 210 and the heat collected from various locations in the main body casing 210 by the wind are arranged on the downstream side of the wind flow with respect to the fan 251. A radiator 252 that discharges is shown. Here, the radiator 252 requires a storage space having a certain thickness in the thickness direction of the main body casing 210. As described above, in this embodiment, in order to secure this storage space, a part of the bottom surface 213 protrudes to the outside of the main body casing 210 from the first bottom surface portion 213a occupying half or more of the bottom surface 213. ing. This protruding bottom surface portion is a second bottom surface portion 213b.

  A slope exhaust port 224 is provided on the slope from the second bottom face portion 213b to the back face 214. A rear exhaust port 225 is provided on the rear surface 214 side by side above the slope exhaust port 224. Here, the slope exhaust port 224 is partitioned into a plurality of openings by a first rib 224a described below, and FIG. 28 shows a cross section of the first rib 224a.

  The first rib 224a is a rib extending in the vertical direction in which two types of exhaust ports 224 and 225 are arranged. The end of the first rib 224a on the rear exhaust port 225 side is located on the downstream side of the wind from the end opposite to the rear exhaust port 225. As a result, the wind that hits the first rib 224a and failed to pass through the inclined surface exhaust port 224 is also pushed up toward the rear exhaust port 225 side by side and exhausted from the rear exhaust port 225. As a result, the wind that has received heat from the radiator 252 is efficiently exhausted, and as a result, the cooling efficiency is improved.

  On the other hand, the rear exhaust port 225 is partitioned into a plurality of openings by the following second ribs 225a in order to suppress a decrease in strength of the main body casing 210.

  29 is a cross-sectional view of the vicinity of the rear exhaust port taken along the cutting line LL in FIG. 27 passing through the second rib.

  FIG. 29 shows a cross section of the second rib 225 a that partitions the back surface exhaust port 225 provided on the back surface 214 side by side above the inclined surface exhaust port 224.

  The second rib 225a is a rib extending in the vertical direction in which two types of exhaust ports 224 and 225 are arranged. The plurality of first ribs 224a that partition the slope exhaust port 224 are alternately arranged as shown in FIG. That is, the plurality of second ribs 225a are positioned above the openings of the slope exhaust ports 224 formed by the plurality of first ribs 224a. By this alternate arrangement, the wind pushed up from the side of the slope exhaust port 224 by the first rib 224a is smoothly exhausted without being blocked by the second rib 225a of the rear exhaust port 225. Thereby, the cooling efficiency is further improved.

  Further, in the present embodiment, the rear exhaust port 225 that is wide in the thickness direction of the main body casing 210 has a structure in order to further reinforce the strength at the location of the rear exhaust port 225 as shown in FIG. A third rib 225b extending in a direction intersecting with the second rib 225a is also provided. In the present embodiment, the third rib 225b is provided at the rear exhaust port 225 for strength reinforcement, but the third rib 225b may not be provided if the strength is sufficient.

  Here, a fourth comparative example for comparison with this embodiment will be described.

  In addition, about this 4th comparative example, it demonstrates only paying attention to the exhaust port in a main body apparatus.

  FIG. 30 is a diagram illustrating an exhaust port in the fourth comparative example.

  This fourth comparative example differs from the present embodiment only in the relative position of the second rib 802a that partitions the rear exhaust port 802 with respect to the first rib 801a that partitions the slope exhaust port 801. In the fourth comparative example, each second rib 802a is disposed on an extension line of each first rib 801a. As a result, the wind pushed up from the slope exhaust port 801 side by the first rib 801a may be blocked by the second rib 802a of the rear exhaust port 802, and the exhaust efficiency may decrease. Further, since the second rib 802a is disposed on the extended line of the first rib 801a, there is no support between the plurality of second ribs 802a and between the plurality of first ribs 801a. The strength of the main body casing 810 is low.

  Compared to the fourth comparative example described above, in the notebook PC 10 of the present embodiment, the plurality of second ribs 225a are alternately arranged with the plurality of first ribs 224a. Smooth operation and improved exhaust efficiency. Further, by this alternate arrangement, the first ribs 224a are reinforced by the second ribs 225a, and the second ribs 225a are reinforced by the first ribs 224a. That is, in this embodiment, the exhaust efficiency is increased while suppressing a decrease in the housing strength.

  In the present embodiment, the exhaust ports 224 and 225 are provided on the back side opposite to the front side where the keyboard 201 exists in the main body casing 210, that is, on the side opposite to the user side. Thereby, since the wind which received the heat from the radiator 252 is exhausted to the opposite side to the user, the user's discomfort is avoided.

  Further, in the present embodiment, a slope exhaust port 224 is provided on the slope facing the rear face 214 from the second bottom face portion 213b located on the outer side of the main body casing 210 in order to secure a storage space for the radiator 252. In other words, the present embodiment has an efficient structure in which the inclined exhaust port 224 is provided by effectively utilizing the protruding shape of the bottom surface 213 generated for cooling.

  In the present embodiment, the main device 200 of the notebook PC 10 is illustrated as an example of the electronic device having the exhaust port as described above. However, the electronic device as described above is limited to the main device 200 of the notebook PC 10. is not. Such an electronic device may be, for example, a desktop personal computer or a general electronic device having an exhaust port for exhausting air from the inside of the apparatus to the outside.

  Next, the peripheral structure of the ODD 300 shown in FIG. 1 will be described in detail.

  FIG. 31 is a perspective view showing the periphery of the ODD shown in FIG.

  An opening 212a in which a disk tray 310 included in the ODD 300 is accommodated so as to advance and retreat is opened on the front surface 212 rising from the bottom surface 213 of the main body casing 210. The opening 212a is blocked by the outer surface of the cover 311 of the disc tray 310 when the disc tray 310 is accommodated.

  Here, in the ODD 300, the disc tray 310 is urged toward the outside of the main body device 200 by a spring (not shown). When the disc tray 310 is accommodated, the disc tray 310 is locked against the urging force of the spring. The ODD 300 is provided with an electronic circuit 340 (shown in FIG. 32) for releasing the lock. The outer surface of the cover 311 is provided with a push button 320 for giving a signal indicating the removal of the disc tray 310 to the electronic circuit 340 (shown in FIG. 32) by a pressing operation.

  FIG. 32 is a diagram showing the notebook PC in a state where the disc tray is taken out of the main body housing by a pressing operation on the push button.

  In the disc tray 310, the main body casing 210 side with respect to the cover 311 is a tray portion 312 on which the optical disc 330 is placed. An electronic circuit 340 for releasing the lock as described above is mounted on the tray 312.

  When the push button 320 is pressed while the disc tray 310 is stored, a signal representing the removal of the disc tray 310 is transmitted to the electronic circuit 340. When the electronic circuit 340 releases the lock, the disc tray 310 is pushed out from the opening 212a of the front surface 212 by the biasing force of a spring (not shown).

  Here, in this embodiment, the outer surface of the cover 311 of the disc tray 310 and the pressing surface 321 of the push button 320 attached to the outer surface have the shapes described below.

  FIG. 33 is an enlarged view of the push button shown in FIGS. 31 and 33 and its surroundings.

  The outer side surface of the cover 311 of the disk tray 310 is a first side surface 311a that rises from the bottom surface 213 side of the main body housing 210 and a first side surface 311a that protrudes outward from the first side surface 311a. And two side surfaces 311b.

  The pressing surface 321 of the push button 320 is a surface that extends along the first side surface 311a, part of which is part of the first side surface 311a, and the other part is the bottom of the recess with respect to the second side surface 311b. It has a different shape.

  34 is a cross-sectional view of the push button taken along the cutting line MM in FIG.

  As can be seen from FIG. 34, the upper end portion of the pressing surface 321 of the push button 320 is the bottom of the recess with respect to the second side surface 311b. The push button 320 has a cantilever structure connected to the cover 311 of the disc tray 310 at the end of the pressing surface 321 on the second side surface 311b side. The push button 320 is bent at this end by a pressing operation.

  In addition, a protrusion 322 protruding inside the ODD 300 is provided on the back surface of the push button 320 opposite to the pressing surface 321. Further, a contact portion 323 is provided in the ODD 300 so as to face the tip of the protrusion 322. When the push button 320 is bent as described above by a pressing operation, the protrusion 322 presses the contact portion 323. As a result, the contact is closed, and a signal representing the removal of the disk tray 310 is transmitted to the electronic circuit 340.

  Here, a fifth comparative example for comparison with this embodiment will be described.

  In the fifth comparative example, only the push button provided on the cover of the ODD disc tray will be described.

  FIG. 35 is a cross-sectional view similar to FIG. 34 of the ODD push button in the fifth comparative example.

  In the fifth comparative example, the outer side surface of the cover 911 of the disk tray 910 of the ODD 900 is from a first side surface 911a rising from the bottom surface side of the main body housing and a first side surface 911a connected to the upper side of the first side surface 911a. Also has a second side surface 911b protruding outward.

  The pressing surface 921 of the push button 920 is connected to the cover 911 as a whole and is part of the outer surface of the cover 911. That is, the pressing surface 921 includes a first pressing surface 921a that is a part of the first side surface 911a and a second pressing surface 921b that is a part of the second side surface 911b.

  Here, the front surface of the notebook PC where the cover 911 of the disk tray 910 is located is narrow. Therefore, it is difficult for the user to see the push button 920 attached to the cover 911. In many cases, the user finds and pushes such a push button 920 by groping. However, as in the fifth comparative example, if the shape of the pressing surface 921 of the push button 920 matches the shape of the outer surface of the surrounding cover 911, it is difficult for the user to search for the push button 920 by hand.

  In contrast to the fifth comparative example described above, in the notebook PC 10 of the present embodiment, the upper end portion of the push button 320 is the bottom of the recess with respect to the second side surface 311b as described above. As a result, the user's finger searching for the push button 320 by groping is caught on the step portion between the push button 320 and the second side surface 311b. Thereby, the push button 320 can be easily operated.

  In the present embodiment, the push button 320 has a cantilever structure as described above.

  Here, the fifth comparative example also has a cantilever structure in which the push button 920 is connected to the cover 911 on the upper end side. However, in the cantilever structure in the fifth comparative example, the upper end of the second pressing surface 921 b protruding outward is connected to the cover 911. For this reason, this upper end that is bent by the pressing operation is inclined with respect to the pressing direction so that the pressing force is difficult to be transmitted, and thus it is difficult to bend.

  On the other hand, in this embodiment, the push button 320 has a pressing surface 321 that spreads along the first side surface 311a, and is connected to the cover 311 at the upper end of the pressing surface 321. As a result, this upper end that is bent by the pressing operation intersects with the pressing direction, so that the pressing force is easily transmitted, and it is easy to bend.

  Further, in the present embodiment, the side surface of the recess formed by the second side surface 311b and the pressing surface 321 is a surface that is substantially perpendicular to the pressing surface 321 from the second side surface 311b to the pressing surface 321. ing. On the other hand, it is also conceivable to devise the side surface shape of the recess as in another example described below.

  FIG. 36 is a diagram illustrating another example of the side surface shape of the recess formed by the second side surface and the pressing surface of the cover.

  In another example shown in FIG. 36, the side surface of the recess formed by the second side surface 311b ′ of the cover 311 ′ and the pressing surface 321 is inclined surface 311b′_1 inclined from the second side surface 311b to the pressing surface 321. It has become. In this alternative example, the user's finger searching for the push button 320 also touches the inclined surface 311b'_1 spreading around the upper end of the push button 320, so that the range in which the user can feel the push button 320 is widened. As a result, the user can operate the push button 320 more easily.
