JP-A-2000-339071

Since the light guide lens that constitutes the above-described indicator has various sizes and shapes depending on the installation position in the housing and the housing shape, tape or the like is used on the housing or the sheet metal installed in the housing. In many cases, it is fixed by fitting with an adhesive or claw structure. In particular, notebook-type personal computers and mobile terminals have had a problem in that the housings have been made thinner and smaller, and the workability of assembling (assembling) the light guide lens tends to decrease. In addition, when fixing the light guide lens to the housing, it may be necessary to adjust the shape of the light guide lens with respect to the shape of the housing. ) may be difficult.

Accordingly, one example of the problem to be solved by the present invention is to provide a light guide lens for electronic equipment that can improve workability during assembly and repair and that can be easily standardized.

The light guide lens for an electronic device according to the first aspect of the present invention is capable of coming into contact with the first substrate surface, which is one surface of the substrate on which the first light source is mounted, and guiding the light from the first light source. a second region portion that can abut against a second substrate surface that is a surface on the opposite side of the first substrate surface; The end portion and the second end portion of the second region portion are connected to each other, the substrate is sandwiched between the first region portion and the second region portion, and the first region portion and the second region portion are connected. and a third area portion having a light lead-out portion on the surface opposite to the side.

Further, for example, one of a first contact surface in contact with the first substrate surface of the first region portion and a second contact surface in contact with the second substrate surface of the second region portion may be provided with the substrate. A protrusion that can be inserted into a fixing hole formed in the housing may be formed.

Further, the third area portion includes, for example, a second engaging portion that engages with a first engaging portion formed at an end portion of the substrate when the protrusion is inserted into the fixing hole. good too.

Further, the light lead-out portion may be configured to protrude from the third area portion and be inserted into a lens opening provided in a case main body in which the substrate is accommodated.

For example, the second area section guides light from a second light source mounted on the surface of the second substrate to the light guide section, and the light guide section guides the light from the first area section. It may be possible to emit the light of the first light source, the light of the second light source guided in the second region, or the mixed light of the light of the first light source and the light of the second light source.

According to the above aspect of the present invention, the light guide lens for electronic equipment is attached to the end portion of the substrate in a posture of sandwiching the substrate, and can be handled integrally with the substrate. As a result, workability during assembly and repair can be improved. In addition, since the electronic device light guide lens can be handled integrally with the substrate, standardization can be easily performed without being affected by the shape of the housing that accommodates the electronic device light guide lens.

FIG. 9 is an exemplary and schematic perspective view showing a state in which the board 12 with the light guide lens 10 mounted thereon is attached to the housing of the information processing device M, viewed from the outside of the housing.

The light guiding lens 10 directs light from a light source (for example, an LED (Light-Emitting Diode) 14 or the like) mounted on a substrate 12 arranged inside the housing of the information processing device M to a predetermined position (for example, a housing). It is an optical component for guiding to the body surface indicator L, etc.). The indicator L displays, for example, the power ON/OFF state of the information processing device M by displaying light guided by the light guide lens 10. If the power source is the built-in battery, the power ON/OFF state can be displayed in addition to the charging state. It is possible to display the remaining amount and the like. The indicator L can also indicate the operating state of the information processing device M by displaying light guided by the light guide lens. For example, when the operation of the information processing device M is in a normal operation state, an abnormal state, or an abnormal state, the type of abnormality can be displayed.

As shown in FIG. 2, an LED 14a is mounted as a first light source on a first substrate surface 12a, which is one surface of the substrate 12, for example. The light guide lens 10 of the present embodiment includes a first region portion 16 that can come into contact with the first substrate surface 12a and can guide the light from the LED 14a.

In addition, as shown in FIG. 3, the light guide lens 10 includes a second region portion 18 that can come into contact with the second substrate surface 12b that is the surface opposite to the first substrate surface 12a of the substrate 12 . In addition, in the case of FIG. 3, for example, an LED 14b is mounted as a second light source on the second substrate surface 12b. In this case, the second region portion 18 can guide the light from the LED 14b.

Further, as shown in FIG. 5, the first region portion 16 and the second region portion 18 straddle the substrate end portion 12c in the thickness direction of the substrate 12 having the thickness t, and the first end portion of the first region portion 16 16s (the side opposite to the side facing the LED 14a) and the second end 18s of the second region 18 (the side opposite to the side facing the LED 14b). The third region portion 20 connects the first region portion 16 and the second region portion 18 so that the substrate 12 can be sandwiched therebetween. The third region portion 20 has a light lead-out portion 20a (light-emitting portion of the indicator L) on the surface opposite to the connection side of the first region portion 16 and the second region portion 18 .

The light guide lens 10 can be made of, for example, a transparent or translucent synthetic resin such as polycarbonate or ABS, or a milky-white synthetic resin, and is, for example, a molded product that can be molded as an integral part.

As shown in the cross-sectional view of FIG. 5, the light guide lens 10 has, for example, a substantially J-shaped cross section. In the example shown in FIG. 5, the length of the first region portion 16 on the side of the first substrate surface 12a with respect to the insertion direction X when the light guide lens 10 is attached to the substrate 12 is The length of the second area portion 18 is set short. This shape is an example, and is a shape corresponding to the mounting position of the LED 14 a that supplies light to the first region 16 and the mounting position of the LED 14 b that supplies light to the second region 18 . Therefore, depending on the positions of the LEDs 14a and 14b, the first region 16 may be set shorter than the second region 18, or may be set to have the same length. Further, as shown in FIG. 2, the first area portion 16 is formed in a substantially J-shape when viewed from above, but this shape is to avoid interference with other components on the substrate 12. , the shape in plan view can also be changed as appropriate. For example, it may be rectangular like the second region 18 . In either case, the first region portion 16 has an optical path configured to guide the light from the LED 14a to the light lead-out portion 20a of the third region portion 20, and the second region portion 18 similarly directs the light from the LED 14b to the third region portion. An optical path is configured to guide the light to the light lead-out portion 20a of 20. As shown in FIG. Therefore, when the LED 14a and the LED 14b are made to have different emission colors, it is possible to realize three types of emission colors, ie, two types of single colors and mixed colors. In addition, by changing the pattern of lighting and extinguishing (including blinking pattern) and the pattern of the amount of light emission, the light pattern emitted through the light guide lens 10 can be changed, and various states of the information processing device M can be displayed to the user. can be notified.

Further, as shown in FIG. 5, the LEDs 14a and 14b mounted on the substrate 12 are separately mounted on the front and rear surfaces of the substrate 12. As shown in FIG. As a result, for example, even if the LEDs 14a and 14b emit light of different colors, it is possible to prevent the colors from being mixed with each other before they enter the light guiding lens 10 during light emission. Either one of the LED 14a and the LED 14b may be omitted. In this case, the omitted light guide lens 10 (the first region portion 16 or the second region portion 18) on the LED 14 side may not guide light. In this case, the first region portion 16 and the second region portion 18 only need to have a function of holding the substrate 12 therebetween. It may be made of a light-guiding material or a non-light-guiding color.

The light guide lens 10 of the present embodiment has projections 22 for positioning and preventing it from coming off from the substrate 12 when mounted on the substrate 12 . That is, as shown in FIG. 5, the light guiding lens 10 has a first contact surface 16a that contacts the first substrate surface 12a of the first region portion 16 and a second substrate surface 12b of the second region portion 18. A protrusion 22 that can be inserted into a fixing hole 24 formed in the substrate 12 is formed on one of the second contact surfaces 18 a that contact the substrate 12 . As shown in FIG. 4, the protruding portion 22 has, for example, a substantially elliptical cross section and a tapered upper end portion 22a having a curved surface. Also, as shown in FIG. 5, the fixing hole 24 formed in the substrate 12 has a corresponding elliptical shape slightly larger than the base cross-sectional shape of the protrusion 22 . The fixing hole 24 may be formed so as to pass through the substrate 12 as shown in FIG. 5, or may be formed in a bottomed hole shape. When the fixing hole 24 is a through hole, the light guiding lens 10 attached to the substrate 12 can be easily removed by pushing the projecting portion 22 with a jig or the like from the second substrate surface 12b side. Further, as will be described later, when the fixing hole 24 is a through hole, it is possible to mount in an upside-down posture so that the first contact surface 16a of the first region portion 16 contacts the second substrate surface 12b. On the other hand, when the fixing hole 24 is a hole with a bottom, it is possible to form a wiring pattern or the like at a position corresponding to the fixing hole 24 on the second substrate surface 12b, and the effective area on the second substrate surface 12b side can be increased. The designability of the wiring pattern can be improved. Further, by forming the upper end portion 22a of the protrusion 22 into a curved tapered shape, the protrusion 22 can be easily slid into the fixing hole 24 when the light guiding lens 10 is attached to the substrate 12, thereby facilitating assembly. It can contribute to the improvement of attachment workability. Similarly, when removing the light guide lens 10 from the substrate 12, if the upper end portion 22a has a curved tapered shape, it can be easily removed, which contributes to an improvement in workability.

It is desirable that the protrusion height h of the protrusion 22 is lower than the thickness t of the substrate 12 . In other words, by not protruding from the second substrate surface 12b, it is possible to avoid interference with other components or the like on the second substrate surface 12b side. Further, by setting the protrusion height h of the protrusion 22 to be higher than, for example, 1/2 of the thickness t of the substrate 12, it is possible to easily avoid coming off due to vibration or the like after mounting on the substrate 12. FIG.

5 to 7, the third area portion 20 of the light guiding lens 10 according to the present embodiment is arranged such that when the protrusion 22 is inserted into the fixing hole 24, the substrate end portion 12c of the substrate 12 It has a second engaging portion 20b that engages with a first engaging portion 26 formed in the . As shown in FIG. 7, the second engaging portion 20b includes a first positioning portion 20b1 and a second positioning portion 20b2 formed on the base portion on which the light lead-out portion 20a is formed in the third area portion 20. . The first positioning portion 20b1 is a portion that extends in the orthogonal direction Y along the surface of the substrate 12 (the first substrate surface 12a or the second substrate surface 12b) with respect to the insertion direction X of the light guide lens 10. As shown in FIG. Also, the second positioning portion 20b2 is a portion extending along the insertion direction X. As shown in FIG. Therefore, as shown in FIG. 7, the second engaging portion 20b is, for example, a convex portion formed in a substantially T shape.

The first engaging portion 26 formed on the substrate 12 is a portion formed at the mounting position of the light guide lens 10 at the substrate end portion 12c of the substrate 12, as shown in FIG. The first engaging portion 26 has a shape corresponding to the shape of the second engaging portion 20b, and has a first fitting portion 26a, a second fitting portion 26b, and a second positioning portion 26b corresponding to the shape of the first positioning portion 20b1. A third fitting portion 26c corresponding to the shape of the portion 20b2 is included. The first engaging portion 26 has, for example, a concave shape that is formed slightly large so that it can be loosely fitted with the second engaging portion 20b. That is, the first engaging portion 26 and the fixing hole 24 are formed in a positional relationship corresponding to the forming positional relationship between the protrusion 22 of the light guiding lens 10 and the second engaging portion 20b.

FIG. 6 is an exemplary and schematic perspective view showing how the light guide lens 10 is attached to the substrate. As described above, when the light guide lens 10 having the projection 22 and the second engaging portion 20b is mounted on the substrate 12 having the first engaging portion 26 and the fixing hole 24, the projection 22 is slid into the fixing hole 24. In this case, the first region portion 16 and the second region portion 18 connected to the third region portion 20 bend and spread in the separation direction (thickness direction of the substrate 12). As a result, the projecting portion 22 is fitted into the fixing hole 24 and the second engaging portion 20b is engaged with the first engaging portion 26 to fix the light guide lens 10 at a predetermined position on the substrate 12 (prevent rattling). ) and positioning can be performed simultaneously, and the light guiding lens 10 and the substrate 12 can be integrated. As a result, as shown in FIGS. 5 and 6, for example, the incident portion 16b of the first area portion 16 of the light guide lens 10 faces the LED 14a mounted on the first substrate surface 12a, Light from the LED 14a can be guided toward the light lead-out portion 20a. Similarly, the incident portion 16b of the second region portion 18 of the light guide lens 10 faces the LED 14b mounted on the second substrate surface 12b, and guides the light from the LED 14b toward the light lead-out portion 20a. be able to.

The shapes of the first engaging portion 26 and the second engaging portion 20b may be any shape that can position the light guide lens 10 with respect to the substrate 12, suppress rattling, and match each other. It's okay. For example, one of the first positioning portion 20b1 and the second positioning portion 20b2 may be omitted. In this case, it is possible to contribute to the simplification of the shape of the third region portion 20 . Further, when both the first positioning portion 20b1 and the second positioning portion 20b2 are provided, it is possible to contribute to improvement in positioning accuracy (positioning stability, rattling suppression function). In this embodiment, the first engaging portion 26 has a concave shape and the second engaging portion 20b has a convex shape. The joint portion 20b may have a concave shape, and the same effect can be obtained.

As described above, the light guiding lens 10 mounted on and integrated with the substrate 12 can function as a positioning member for the case body Ma of the information processing device M when the substrate 12 is assembled to the case body Ma. That is, as shown in FIGS. 8 and 9, the light lead-out portion 20a protruding from the third region portion 20 of the light guiding lens 10 is provided in the case main body Ma (housing) in which the substrate 12 is accommodated. The mounting position of the substrate 12 with respect to the case main body Ma can be determined by inserting the substrate 12 into the lens opening 28 .

As shown in FIG. 9, the lens opening 28 is an emission port for the indicator L formed on the side surface M1 of the case body Ma of the information processing device M, and can be formed to penetrate the case body Ma. . The light lead-out portion 20a is inserted in the thickness direction of the case main body Ma, but the protrusion height is designed so as not to protrude from the case main body Ma (side surface M1), or the light guide lens 10 is attached. When fixing the substrate 12 to the case main body Ma, it is desirable to design the fixing position of the substrate 12 so that the light lead-out portion 20a does not protrude from the case main body Ma (side surface M1). In this manner, the substrate 12 integrated with the light guide lens 10 is inserted into the lens opening 28 so that the light lead-out portion 20a of the light guide lens 10 does not protrude from the case main body Ma (side surface M1). It can be easily positioned with respect to the main body Ma, and workability can be improved when the substrate 12 with the light guide lens 10 is assembled to the case main body Ma. Further, by preventing the light lead-out portion 20a from protruding from the case main body Ma (side surface M1), it is possible to prevent the light lead-out portion 20a from being subjected to a load (contacting an object) when the information processing device M is used. Thus, damage to the light guide lens 10 can be avoided. A cover may be attached to the open end of the lens opening 28 on the front side. In this case, it is possible to protect the light lead-out portion 20a and prevent dust from entering the case main body Ma.

According to the light guiding lens 10 configured in this way, when designing the case main body Ma of the information processing device M, only the formation position of the lens opening portion 28 need be specified, and the case of the information processing device M is designed. This eliminates the need for shape adjustment between the main body Ma (housing shape) and the light guide lens 10, contributing to an improvement in the degree of freedom in designing the light guide lens. In addition, since the shape of the light guide lens 10 is not affected by the shape of the case main body Ma of the information processing device M, the standardization of the light guide lens 10 (common parts among many models) becomes possible, resulting in cost reduction and parts management. can contribute to the improvement of In addition, since the light guide lens 10 can be integrated with the substrate 12 and then assembled to the case body Ma, workability during assembly and repair is improved compared to the case where the light guide lens is assembled alone to the case body Ma. can be improved.

Next, mounting variations of the light guide lens 10 of the present embodiment will be described with reference to FIGS. 10 to 13. FIG. As described above, since the light guide lens 10 of the present embodiment can be easily standardized, it is possible to easily perform double mounting, triple mounting, and the like. FIG. 10 is an exemplary and schematic perspective view showing a state in which two light guiding lenses 10 are mounted (mounted) on the substrate 12 . FIG. 11 is an exemplary and schematic perspective view of the substrate 12 on which the light guide lens 10 shown in FIG. 10 is mounted, viewed from the reverse surface side (second substrate surface 12b side). Also, FIG. 12 is an exemplary and schematic perspective view showing a state in which the light guide lens 10 is attached to the substrate 12 in an upside-down posture unlike the case of FIG. 10 . FIG. 13 is an exemplary and schematic perspective view of the substrate 12 on which the light guide lens 10 shown in FIG. 12 is mounted, viewed from the reverse surface side (second substrate surface 12b side).

As shown in FIG. 10, the first light guide lens 10A and the second light guide lens 10B are the same as the light guide lens 10 shown in FIGS. is attached to the substrate 12 in a posture straddling the substrate end portion 12c so as to abut on the first substrate surface 12a. In the case of FIG. 10, an LED 14a that supplies light to the first area portion 16A of the first light guide lens 10A is arranged on the first substrate surface 12a of the substrate 12, and the light from the LED 14a is directed to the first light guide portion. 20aA, the LED for the first area portion 16B of the second light guide lens 10B is not mounted. Instead, as shown in FIG. 11, an LED 14b is arranged on the second substrate surface 12b of the substrate 12 to supply light to the second area portion 18B of the second light guide lens 10B. Although the light is guided to the second light lead-out portion 20aB, the LED for the second region portion 18A of the first light guide lens 10A is not mounted. In another embodiment, the LED 14a for the first light guide lens 10A and the LED 14b for the second light guide lens 10B are arranged on either one of the same surface of the substrate 12 (first substrate surface 12a or second substrate surface 12b). may be concentrated and arranged.

As shown in FIGS. 10 and 11, when the first light guide lens 10A and the second light guide lens 10B are mounted in series to emit monochromatic light, the LEDs 14a and 14b are arranged separately on the front and back sides of the substrate 12. , or any one of them, the degree of freedom in mounting the LEDs 14a and 14b can be improved. 1 to 9, the LEDs 14a and 14b may be mounted on the first light guide lens 10A and the second light guide lens 10B, respectively, to enable multicolor light emission. Further, in the case of double mounting of the first light guide lens 10A and the second light guide lens 10B, the substrate 12 can be positioned at two points when assembled to the case main body Ma, thereby improving the positioning accuracy.

Next, with reference to FIGS. 12 and 13, an example in which the first light guide lens 10A and the second light guide lens 10B are double-mounted and the substrate 12 is mounted in a reversed orientation will be described. 10 and 11, the first light guiding lens 10A and the second light guiding lens 10B are the same as the light guiding lens 10 shown in FIGS. As shown in FIG. 12 , the first light guide lens 10A is attached so that the first area portion 16A contacts the first substrate surface 12a of the substrate 12. As shown in FIG. On the other hand, the second light guide lens 10B is mounted so that the second area portion 18B contacts the first substrate surface 12a. The first light guiding lens 10A and the second light guiding lens 10B are mounted on the substrate 12 in a posture straddling the substrate end portion 12c. Therefore, as shown in FIG. 13, the second area portion 18A of the first light guide lens 10A is mounted so as to abut on the second substrate surface 12b of the substrate 12. As shown in FIG. Also, the second light guide lens 10B is mounted so that the first area portion 16A contacts the second substrate surface 12b. In the case of FIG. 12, an LED 14a that supplies light to the first area portion 16A of the first light guiding lens 10A is arranged on the first substrate surface 12a, and the light from the LED 14a is guided to the first light lead-out portion 20aA. The LED for the second region portion 18B of the second light guide lens 10B is not mounted. Instead, as shown in FIG. 13, an LED 14b that supplies light to the first area portion 16B of the second light guide lens 10B is arranged on the second substrate surface 12b of the substrate 12, and the light from the LED 14b is arranged. Although the light is guided to the second light lead-out portion 20aB, the LED for the second region portion 18A of the first light guide lens 10A is not mounted. In another embodiment, the LED 14a for the first light guide lens 10A and the LED 14b for the second light guide lens 10B are arranged on either one of the same surface of the substrate 12 (first substrate surface 12a or second substrate surface 12b). may be concentrated and arranged.

As shown in FIGS. 12 and 13, when the first light guide lens 10A and the second light guide lens 10B are mounted in series to emit monochromatic light, the LEDs 14a and 14b are mounted separately on the front and back sides of the substrate 12. Alternatively, the LEDs 14a and 14b can be mounted more flexibly. 1 to 9, the LEDs 14a and 14b may be mounted on the first light guide lens 10A and the second light guide lens 10B, respectively, to enable multicolor light emission. Further, in the case of double mounting of the first light guide lens 10A and the second light guide lens 10B, the substrate 12 can be positioned at two points when assembled to the case main body Ma, thereby improving the positioning accuracy.

In this way, by forming the first light guiding lens 10A and the second light guiding lens 10B into a shape (reverse shape) that can be mounted in a reversed posture, the first substrate surface 12a and the second substrate surface 12b of the substrate 12 are Interference with other mounted components can be easily avoided, and the degree of freedom in board design can be improved. In the examples of FIGS. 10 to 13, an example in which two light guide lenses 10 are mounted is shown, but the number of mounted light guide lenses 10 can be changed as appropriate, and multiple mounting of three or more is possible, and the same effect can be obtained. can be obtained. In the examples of FIGS. 10 to 13, the first light guide lens 10A and the second light guide lens 10B are arranged close to each other. For example, they may be arranged at both ends of the substrate 12 or the like. In this case, the workability of positioning the substrate 12 by the first light lead-out portion 20aA and the second light lead-out portion 20aB is further improved when assembled to the case main body Ma.

In the above-described embodiment, an example in which the indicator L (the lens opening 28: the insertion position of the light lead-out portion 20a) is formed on the side surface M1 of the information processing device M is shown. good. For example, it may be formed on the same surface as the keyboard arrangement surface of the information processing device M or the same surface as the display arrangement surface. In this case, the light lead-out portion 20a of the light guiding lens 10 mounted so as to sandwich the substrate 12 is formed, for example, in an upright posture from the first substrate surface 12a (or the second substrate surface 12b) of the substrate 12. The direction of light emission can be adjusted by setting

Further, in the above-described embodiment, an example in which the light guiding lens 10 is applied to the information processing device M (for example, a notebook personal computer) has been shown. It may be applied to other electronic devices, and similar effects can be obtained. In particular, it is effective for electronic devices in which housings are becoming smaller and thinner, and the workability of assembling the light guide lens is low.
