Japanese Patent Laid-Open No. 2000-293250 Japanese Laid-Open Patent Publication No. 2005-67228

  By the way, the shift lever device has a shift lever that passes through a gate groove (referred to as a guide groove in Patent Document 1 and referred to as a shift hole in Patent Document 2) formed in the housing. A shift lever is operated along the groove. For this reason, from the viewpoint that the operation direction of the shift lever can be easily grasped even when the interior of the vehicle is dark, it is preferable to cause the inner peripheral edge of the gate groove to emit light.

  However, such a gate groove is a through hole, and the shift lever passes therethrough, and the shift lever moves inside thereof. For this reason, it is difficult to provide a light emitter such as a lamp inside the gate groove, and if an inner peripheral edge portion of the gate groove is caused to emit light, spots are generated depending on the light emitting portion.

  In consideration of the above facts, the present invention can emit light at the inner peripheral portion of the gate groove through which the shift lever passes, and there is no light emission spot for each light emitting part, or such light emission spots are small. Is the purpose.

  A shift lever device according to a first aspect of the present invention includes a housing in which a gate groove is formed through a partition wall whose surface faces the vehicle interior side, and the gate groove penetrates the gate groove so as to be movable along the gate groove. A shift lever that is provided in a state of being changed and can be changed to a shift range corresponding to the predetermined position among a plurality of shift ranges set in the transmission of the vehicle by moving to a predetermined position along the gate groove And a light source provided on the back side of the partition wall, a hole through which the shift lever passes so as to be movable along the gate groove, and allows the light emitted by the light source to be incident on the partition wall. The light of the light source that is provided on the rear surface side and is incident on the inside and propagates inside is reflected to the side of the partition wall or the opposite side, and directly to the side of the partition wall through other reflecting means. Light directly or between And a light guide formed along the inner periphery of the hole, and further reflecting light per unit area of the light emitting part as viewed from the partition wall side or the opposite side. The amount is increased or decreased based on at least one of the positional relationship between the light source and the hole and the shape of the inner periphery of the hole.

  In the shift lever device according to the first aspect of the present invention, the light incident on the light guide from the light source travels inside the light guide. When the light traveling through the light guide reaches the light emitting part, it is reflected by the light emitting part. The reflection direction of the light at the light emitting portion is the partition wall side of the housing or the opposite side. For this reason, if the reflection direction of the light in the light emitting part is the partition wall side, the light reflected by the light emitting part is directly guided to the partition wall side. On the other hand, if the reflection direction of the light at the light emitting portion is opposite to the partition wall, the light reflected at the light emitting portion is further reflected by another reflecting means and indirectly to the partition wall side. Led. Since the light emitting part is formed along the inner peripheral part of the hole part formed in the light guide, the light guide emits light around the hole part by the light guided to the partition wall side as described above. Further, since the hole portion of the light guide has a shape corresponding to the gate groove formed in the partition wall of the housing, the light is guided directly or indirectly to the partition wall side, and the edge of the gate groove and The vicinity is illuminated by light.

  Here, in the shift lever device according to the present invention, the reflection amount of light per unit area of the light emitting portion viewed from the partition wall side or the opposite side of the light guide is determined by the positional relationship between the light source and the hole portion and the hole portion. It increases or decreases based on at least one of the shapes of the inner periphery. For this reason, for example, when a light emitting spot occurs when the reflecting part is not formed or when the reflectance of the reflecting part is uniform in each part of the reflecting part along the circumferential direction of the hole, Depending on the positional relationship between the light source and the hole and the shape of the inner peripheral part of the hole, the amount of reflected light per unit area in the reflecting part is increased or decreased, thereby eliminating emission spots, or , Such emission spots can be reduced.

  The light guide is provided on the back side of the partition wall of the housing, and the shift lever that has passed through the hole of the light guide further passes through the gate groove of the housing, and the shift lever is operated along the gate groove. Therefore, as described above, the edge portion of the gate groove and the vicinity thereof are illuminated with light, and the light emitting spots of the light emitting portion along the circumferential direction of the hole portion of the light guide are small, so that the interior of the vehicle can be Even if it is dark, the shape of the gate groove can be easily grasped and looks good.

  A shift lever device according to a second aspect of the present invention is the shift lever device according to the first aspect of the present invention, wherein the amount of light reflected per unit area of the light emitting portion is along the inner peripheral portion of the hole portion. It is characterized in that a large number of sites are set farther than sites that are closer to the light source.

  In the shift lever device according to the second aspect of the present invention, the light guide has a hole. Therefore, when the light of the light source incident on the light guide reaches the side opposite to the light source through the hole, the light bypasses the hole. In this way, when light bypasses the hole, a part of the light is reflected or scattered by other light emitting parts before reaching the position on the opposite side to the light source. For this reason, the part of the light emitting part far from the light source along the circumferential direction in the hole part of the light emitting part as compared to the part near the light source, like the part of the light emitting part along the circumferential direction of the hole part. As a result, the amount of light reaching is reduced. Therefore, if the amount of light reaching the edge of the gate groove and the vicinity thereof corresponds to the amount of light reaching each part of the light emitting portion along the circumferential direction of the hole, naturally, the edge of the gate groove Luminous spots occur at the part and its vicinity.

  Here, in the shift lever device according to the present invention, the amount of reflection of light per unit area of the light emitting portion viewed from the partition wall side or the opposite side is from the light source along the inner peripheral portion of the hole portion of the light guide. A larger number is set at a far site than a near site. For this reason, as described above, the amount of light that reaches the partition wall after being reflected by a portion of the light emitting portion that is far from the light source along the inner peripheral portion of the hole, and the distance from the light source is It is possible to eliminate a difference from the light emission amount at a close site or to reduce such a light emission amount difference. Thereby, the light emission spots of the light emitting part along the circumferential direction of the hole, that is, the light emission spots of the light emitting part along the circumferential direction of the gate groove can be eliminated, or such light emission spots can be reduced.

  A shift lever device according to a third aspect of the present invention is the shift lever device according to the first or second aspect, wherein each of the light transmitted through the light guide is on the side of the partition wall or on the opposite side. The light emitting portion is configured by a plurality of reflecting portions that reflect toward the surface, and the formation density of the light emitting portions per unit area is close to the distance from the light source along the inner peripheral portion of the hole portion. It is characterized by the fact that it is set a lot at a far site compared to.

  In the shift lever device according to the third aspect of the present invention, the light emitting portion of the light guide is formed with a plurality of reflecting portions that reflect the light traveling inside the light guide toward the partition wall. The reflective portion reflects light toward the partition wall or the opposite side. If the reflection direction of the light at the reflection part is the partition wall side, the light reflected by the reflection part is directly guided to the partition wall side. On the other hand, if the reflection direction of the light at the reflection part is opposite to the partition wall, the light reflected by the reflection part is further reflected by another reflection means and indirectly to the partition wall side. Led. As a result, the edge of the gate trench and the vicinity thereof are illuminated with light.

  Here, the formation density of the reflection part per unit area of the light emitting part on the surface facing the partition wall in the light guide is a part far from the part where the distance from the light source along the inner peripheral part of the hole part is short Many are set. This eliminates the difference between the amount of light emitted to the side of the partition wall at a site far from the light source along the inner periphery of the hole and the amount of light emitted from the site far from the light source. Alternatively, such a difference in light emission amount can be reduced.

  The shift lever device according to a fourth aspect of the present invention is the shift lever device according to the third aspect of the present invention, wherein the light from the light source is incident on a light guide model having the light emitting unit eliminated from the light guide. The formation density of the reflection part in the light emitting part of the light guide is increased or decreased according to the amount of light leakage from the inner peripheral part of the hole part of the light guide model.

  In the shift lever device according to the fourth aspect of the present invention, when light from a light source is incident on a light guide model having a configuration in which the light emitting portion is eliminated from the light guide, the inner peripheral portion of the hole portion of the light guide model The formation density of the reflection portion in the light guide is increased or decreased according to the amount of light leakage from the light guide. That is, in such a light guide model, at a position where the amount of light leakage from the inner peripheral portion of the hole portion is small, if the formation density of the reflecting portion is made uniform along the circumferential direction of the hole portion, The amount of light emitted to the is reduced. For this reason, in such a part, the amount of light emission can be increased by setting the formation density of the reflection part more than other parts, and as a result, in each part of the light emitting part along the circumferential direction of the hole part. The difference in the light emission amount can be eliminated or the difference in the light emission amount can be reduced.

  In the present invention, the density of the reflection part at the light emitting part in the light guide is set corresponding to the amount of light leakage from the inner peripheral part of the hole part when light from the light source is incident on the light guide model. It only has to be. Therefore, the density of the reflection part may be set by actually using the light guide model, or the density of the reflection part may be set by performing a simulation assuming that the light guide model is used.

  However, according to the present invention, as a result, the density of the reflection part at the light emitting part in the light guide corresponds to the amount of light leakage from the inner peripheral part of the hole part when light from the light source is incident on the light guide model. In practice, it is not necessary to set the density of the reflection portion using the light guide model, or to perform a simulation assuming that the light guide model is used.

  As described above, the shift lever device according to the present invention can cause the inner periphery of the gate groove to emit light, and has no light emission spots along the circumferential direction of the gate groove, or the circumferential direction of the gate groove. It looks good because there are few light emission spots along the line.

<Configuration of First Embodiment>
FIG. 4 is an exploded perspective view showing the configuration of the main part of the shift lever device 10 according to the first embodiment of the present invention.

  As shown in this figure, the shift lever device 10 includes an upper housing 14 constituting a housing 12. The upper housing 14 includes an upper wall 16 as a partition wall. The upper wall 16 is formed in a substantially rectangular shape in plan view with the surface on the front side facing the vehicle interior side. A gate groove 18 is formed in the upper wall 16. A shift lever 20 is disposed through the gate groove 18. The shift lever 20 has a main body formed in a rod shape, and the longitudinal base end thereof is a frame portion (not shown) of the shift lever device 10 provided on the back side of the upper wall 16 via a connecting member (not shown). ) Is pivotally supported around an axis whose axial direction is both the longitudinal direction and the width direction of the upper wall 16.

  A lower housing 22 that constitutes the housing 12 together with the upper housing 14 is provided on the back side of the upper wall 16. One or more holding portions 24 are provided on both sides (only one side is shown in FIG. 4) of the lower housing 22 along the width direction of the upper wall 16. A fitting piece 26 having a spring property is formed on both sides (only one side is shown in FIG. 4) of the upper housing 14 along the width direction of the upper wall 16 corresponding to the holding portion 24.

  The upper housing 14 and the lower housing 22 are integrally connected to each other when the fitting piece 26 is fitted to the holding portion 24 in a state where the upper housing 14 and the lower housing 22 face each other. The housing 12 formed by connecting the upper housing 14 and the lower housing 22 in this manner is integrally connected to a predetermined portion in the vehicle compartment or the frame portion of the shift lever device 10 described above.

  On the other hand, a cover slide 28 is arranged on the lower housing 22 side of the upper housing 14. The cover slide 28 is formed in a flat plate shape that can be bent around an axis whose axial direction is the width direction of the upper wall 16. The cover slide 28 is formed with a long hole 30 whose longitudinal direction is along the width direction of the upper wall 16, and the shift lever 20 that has passed through the gate groove 18 passes through the long hole 30. When the shift lever 20 is pivoted in the longitudinal direction of the upper wall 16 around an axis whose center is the width direction of the upper wall 16 with the base end side as the center, the inner periphery of the long hole 30 is formed in the shift lever 20. Thus, the cover slide 28 slides in the longitudinal direction of the upper wall 16.

  Corresponding to both ends of the cover slide 28 in the longitudinal direction, the upper housing 14 is formed with a guide portion 32 whose front end is curved toward the back side of the upper housing 14 about an axis whose axial direction is the width direction of the upper wall 16. ing. As described above, when the cover slide 28 slides in the longitudinal direction of the upper wall 16, the cover slide 28 is pressed by the guide portion 32 on the slide direction side, and bends following the guide portion 32.

  Further, the cover slide 34 can slide along the width direction of the cover slide 28 (that is, the width direction of the upper wall 16) on the back surface side of the cover slide 28 (that is, between the cover slide 28 and the lower housing 22). Is supported by a cover slide 28. The cover slide 34 is formed with a hole 36 that is slightly larger than the outer peripheral shape of the shift lever 20 to the extent that the shift lever 20 can pass therethrough. The base end side in the longitudinal direction of the shift lever 20 that has passed through the long hole 30 passes through the hole 36.

  When the shift lever 20 is rotated in the width direction of the upper wall 16 around an axis whose axial direction is the longitudinal direction of the upper wall 16 around the base end side, the shift lever 20 is moved to the inner periphery of the long hole 30. The inner periphery of the hole 36 is pressed while moving the inside of the long hole 30 along the longitudinal direction of the long hole 30 without pressing the part, and the long hole 30 is moved in the width direction of the cover slide 28 (that is, the upper wall 16 in the width direction), and the cover slide 34 is slid.

  On the other hand, a light guide 40 is disposed on the upper wall 16 side of the cover slide 28 (that is, between the cover slides 28 and 16). The light guide 40 is formed in a plate shape with a transparent material such as polymethyl methacrylate (PMMA), for example, and the lower housing 22 with the surface (front surface) on one side in the thickness direction facing the back surface of the upper wall 16. A light source 42 is provided in the vicinity of the end of the light guide 40 on one side in the width direction of the upper housing 14 that is supported (or held).

  The light source 42 is configured by a light emitting diode or a light bulb, and is held by the lower housing 22 on the back surface side of the light guide 40 (that is, the side opposite to the upper wall 16), and can emit light toward the light guide 40 side. It is said that. The light source 42 is connected to a battery mounted on the vehicle via a driver (not shown) and to an ECU as a control means. For example, when a vehicle headlight is turned on, the light source 42 emits light in conjunction with the light. It is configured to do.

  Further, a hole 44 is formed in the light guide 40 corresponding to the gate groove 18 formed in the upper wall 16. The longitudinal base end side of the shift lever 20 that has passed through the gate groove 18 passes through the hole 44, and the shift lever 20 that has passed through this hole 44 passes through the long hole 30 of the cover slide 28, and further, the cover It passes through the hole 36 of the slide 34. Even though the hole 44 has a shape similar to that of the gate groove 18 or a shape different from that of the gate groove 18, at least the shift lever 20 rotates in the longitudinal direction and the width direction of the upper housing 14 along the hole 44. The inner peripheral portion is formed in a shape that does not interfere with the shift lever 20 when moved.

  As shown in FIG. 1, a certain range (not a cross-section but outside of the inner peripheral portion of the hole 44 and along the inner peripheral portion of the hole 44 is hatched for convenience to clearly show the range. The inserted portion) is a light emitting portion 46. Here, FIG. 2 shows a perspective view from the back side of the light guide 40 in which the light emitting portion 46 is enlarged, and FIG. 3 shows an enlarged cross-sectional view of the light guide 40 in the light emitting portion 46. As shown in these drawings, a plurality of reflecting portions 48 are formed on the light guide 40 in the light emitting portion 46. These reflecting portions 48 are recessed portions opened on the back surface of the light guide 40 (the surface opposite to the upper housing 14 along the thickness direction of the light guide 40).

  These reflecting portions 48 have a substantially truncated cone shape in which the inner diameter dimension gradually increases toward the opening end on the back surface of the light guide 40. The inner peripheral surface of these reflecting portions 48 is a reflecting surface 50. As described above, the reflecting portion 48 has a substantially truncated cone shape in which the inner diameter dimension gradually increases toward the opening end on the back surface of the light guide 40. For this reason, the reflecting surface 50 is inclined with respect to the thickness direction of the light guide 40. For this reason, as shown in FIG. 3, when the light L passing through the inside of the light guide 40 reaches the reflecting surface 50, it is reflected by the reflecting surface 50 and is opposite to the opening direction of the reflecting portion 48, that is, the upper wall. 16 is directed to the side opposite to 16, that is, the cover slide 28 side.

  Further, the light reflected by the reflecting surface 50 toward the cover slide 28 in this way is reflected by the cover slide 28 and formed on the upper wall 16 side, particularly, the gate groove formed on the upper wall 16. The inclination angle of the reflecting surface 50 is set so as to go to the vicinity of 18. In the present embodiment, the cover slide 28 that further reflects the light reflected by the reflecting surface 50 in this way and directs it toward the upper wall 16 is another reflecting means in the claims. Equivalent to.

  Further, when the light emitting unit 46 is viewed from one side in the thickness direction of the light guide 40 (on the upper wall 16 side) or the opposite side, the density of the reflecting unit 48 per unit area is the highest at the position closest to the light source 42. The density of the reflection part 48 gradually and gradually as it moves away from the light source 42 toward both the circumferential direction one side (arrow A1 direction in FIG. 1) and the other circumferential direction other side (arrow A2 direction in FIG. 1) of the hole 44. Further, the reflection portion 48 is formed so that the density of the reflection portion 48 is maximized at a position farthest from the light source 42 along both circumferential directions of the hole portion 44.

<Operation and Effect of First Embodiment>
Next, the operation and effect of the present embodiment will be described.

  In the shift lever device 10 having the above configuration, when the headlight of the vehicle is turned on, the light source 42 emits light in conjunction with this. Since the light source 42 emits light toward the back surface of the light guide 40 (the surface opposite to the upper wall 16), the light emitted from the light source 42 enters the light guide 40 from the back surface of the light guide 40.

  A part of the light incident on the light guide 40 passes through the light guide 40 in the thickness direction of the light guide 40, but the other part is reflected on the front side (surface on the upper wall 16 side) of the light guide 40. Pass through the inside of the light guide 40. When the light passing through the inside of the light emitting unit 46 reaches the reflecting unit 48 of the light emitting unit 46, the light is reflected by the reflecting surface 50 toward the cover slide 28 and transmitted from the back surface of the light guide 40 to the outside of the light guide 40. . As a result, the light guide 40 emits light toward the cover slide 28 at the light emitting portion 46.

  Further, the light reflected by the reflecting surface 50 and directed toward the cover slide 28 is further reflected by the cover slide 28 and is near the upper wall 16 side, particularly in the vicinity of the gate groove 18 formed in the upper wall 16. Head to.

  By the way, when the light L passing through the light guide 40 reaches the light guide 40 on the opposite side of the light source 42 via the light emitting unit 46, the light L bypasses the light emitting unit 46. For this reason, compared with the vicinity of the light source 42 in the reflection part 48, the part on the opposite side to the light source 42 via the light emission part 46, especially both the circumferential direction of the hole 44 (arrow A1 direction and arrow A2 direction of FIG. 1). The light L hardly reaches the part farthest from the light source 42 along the two points (that is, the part of the reflector 48 far from the light source 42 has a smaller amount of light L per unit area than the part near it). ).

  Here, when the light guide 40 is viewed from the side of the upper wall 16 or the opposite side, the formation density of the reflection parts 48 in the light emitting part 46 is the smallest at the position closest to the light source 42 and both in the circumferential direction of the hole 44. As the distance from the light source 42 increases, the density of the reflecting portion 48 gradually increases, and further, the density of the reflecting portion 48 becomes maximum at a position farthest from the light source 42 along both circumferential directions of the hole 44. Therefore, in each part along the circumferential direction of the hole 44, the amount of light L that reaches the light source 42 decreases along with the circumferential direction of the hole 44, but the light L 42 decreases along the circumferential direction of the hole 44. Since the reflection amount of the light L per unit area increases as the distance from the distance increases, the light emission amount toward the cover slide 28 at each portion of the light emitting portion 46 along the circumferential direction of the hole 44, and consequently the cover slide. 28, the difference in the amount of light emitted toward the upper wall 16 side becomes smaller (that is, light emission spots toward the upper wall 16 side at each part of the light emitting portion 46 along the circumferential direction of the hole 44 are reduced). .

  As described above, since the hole 44 of the light guide 40 is formed corresponding to the gate groove 18 of the upper wall 16, the light emitting portion 46 emits light toward the cover slide 28, and this light is further transmitted to the cover slide. 28 reflects to the side of the upper wall 16 so that the shape of the gate groove 18 can be easily and clearly grasped even when the vehicle interior is dark at night or the like. For example, the shift in the target gate groove 18 The position and the like of the lever 20 can be easily and clearly grasped. In addition, the light emission spots on the side of the cover slide 28 at each portion of the light emitting section 46 along the circumferential direction of the hole 44 are small, and accordingly, the reflection spots on the cover slide 28 are also reduced. Even in the vicinity of the inner peripheral portion of the groove 18, emission spots are reduced and the appearance is very good.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. In the description of the present embodiment, the same reference numerals are assigned to the same parts as those in the first embodiment, and the detailed description thereof is omitted.

  FIG. 5 shows a plan view of the light guide 72 of the shift lever device 70 according to the present embodiment. As shown in FIG. 1, in the first embodiment, the light source 42 is disposed on the back side of the light guide 40 near the end of the light guide 40 on one side in the width direction of the upper housing 14.

  On the other hand, as shown in FIG. 5, in the present embodiment, the vicinity of the end of the light guide 72 on one side in the longitudinal direction of the upper housing 14 (the end of the light guide 72 on the lower side of FIG. 5). Near the edge of the light guide 72 on the other side in the width direction of the upper housing 14 (near the edge of the light guide 72 on the right side in FIG. 5). It is arranged in a state of facing. For this reason, in the present embodiment, light is incident from a portion of the outer peripheral portion of the light guide 72 that faces the light source 42.

  Also in the present embodiment, the light emitting portion 46 is formed along the inner peripheral portion of the hole 44 formed in the light guide 72. Also in the present embodiment, when the light emitting unit 46 is viewed from one side (the upper wall 16 side) in the thickness direction of the light guide 72 or the opposite side, the density of the reflecting unit 48 per unit area is basically the light source. The density of the reflection part 48 gradually increases as it moves away from the light source 42 toward both the circumferential direction of the hole 44 and further the light source 42 along both the circumferential direction of the hole 44. The reflection portion 48 is formed so that the density of the reflection portion 48 is maximized at a position farthest from the center. However, in the present embodiment, high density portions 82, 84, 86 are set in a part of the light emitting portion 46. In these high-density portions 82, 84, 86, the density of the reflection portion 48 is higher than the portion adjacent to the high-density portions 82, 84, 86 at portions other than the high-density portions 82, 84, 86 of the light emitting portion 46.

  Here, FIG. 6 shows a plan view of the light guide model 100 which is basically the same in structure as the light guide 72 but does not have the light emitting portion 46 including the high density portions 82, 84 and 86. Yes. As shown in this figure, the light source 42 is arranged in the light guide model 100 as well as the light guide 72. When light emitted from the light source 42 is incident on the inside of the light guide model 100 from a part of the outer periphery of the light guide model 100, the light guide model 100 forms the light emitting portion 46 including the high density portions 82, 84, and 86. Accordingly, the hole 102 of the light guide model 100 corresponding to the hole 44 in the light guide 72 emits light.

  When the inner peripheral portion of the hole 102 is caused to emit light in this manner, the hole portion is caused by the shape of the hole 102, the relative positional relationship between each part of the inner peripheral portion of the hole 102 and the light source 42, or the like. Of the inner peripheral portion of 102, the portion surrounded by the dashed-dotted ellipse B1 and the dashed-dotted circles B2 and B3 has a clearly smaller light emission amount than the other portions. That is, the portion surrounded by the dashed-dotted ellipse B1 and the dashed-dotted circles B2 and B3 is the shape of the hole 102, the relative positional relationship between the light source 42 and each part of the inner peripheral portion of the hole 102, etc. This is a site where the light from the light source 42 is difficult to reach due to the above.

  The high density portion 82 in the light guide 72 is provided corresponding to the portion surrounded by the dashed line ellipse B1 in the hole portion 102 of the light guide model 100, and the high density portion 84 in the light guide 72 is the light guide model 100. The high-density portion 86 in the light guide 72 is a one-dot chain line circle B3 in the hole portion 102 of the light guide model 100. It is provided corresponding to the enclosed part.

  As described above, the light from the light source 42 is difficult to reach due to the shape of the hole 102, the relative positional relationship between each part of the inner periphery of the hole 102 and the light source 42, and the like. Also, the density of the reflection part 48 is set high. Therefore, even if the amount of light from the light source 42 reaching each part of the high density portions 82, 84, 86 is small, the light toward the upper wall 16 per unit area in the high density portions 82, 84, 86 is small. The amount of light emitted to the cover slide 28 side in the high density portions 82, 84, 86 and the side of the upper wall 16 in the portion other than the high density portions 82, 84, 86 in the light emitting portion 46 are increased. The difference from the amount of light emitted to the is reduced.

  As a result, light emission spots on the cover slide 28 side at each part of the light emitting part 46 along the circumferential direction of the hole 44 can be further reduced, and as a result, there are few light emission spots near the inner peripheral part of the gate groove 18. Become more attractive.

  In the present embodiment, the light guide model 100 is used to determine the shape of the hole 102 and the relative positional relationship between the light source 42 and each part of the inner periphery of the hole 102 from the light source 42. Although the portion where light is difficult to reach (that is, the portion surrounded by the dashed-dotted ellipse B1 and the dashed-dotted circles B2 and B3) is specified, the light guide model 100 is not actually used. Using computer simulation assumed to be used, the region where the light from the light source 42 is difficult to reach due to the shape of the hole 102, the relative positional relationship between the light source 42 and each region of the inner peripheral portion of the hole 102 is identified May be.

  In each of the above embodiments, the reflecting portion 50 reflects the light passing through the light guide 40 toward the cover slide 28, and the cover slide 28 reflects toward the upper wall portion 16. In this way, the periphery of the gate groove 18 is illuminated, that is, the light indirectly reflected by the reflecting portion 50 via the other reflection means called the cover slide 28 reaches the periphery of the gate groove 18. However, the light passing through the light guide 40 may be reflected by the reflecting portion 50 toward the upper wall 16 to illuminate the periphery of the gate groove 18.
