The light shielding portion 123b includes a light shielding flange 123ba that covers the light transmissive flange 123ac from above.

  The light transmissive flange 123ac and the light shielding flange 123ba form a flange portion of the third light guide member 123. If the portion where the flange portion of the third light guide member 123 is removed is referred to as the third light guide member 123, the flange portion is a portion protruding from the plate-shaped third light guide member main body. In addition, you may make it form this flange part only from light-shielding flange 123ba. As shown in FIG. 2 and the like (omitted in FIG. 1), the length of the flange portion in the vertical direction from the upper surface 107x of the second housing member 107 is around the third insertion hole 108c of the second housing member 107. A third stepped portion 107 cc is provided which is lowered by (the thickness of the flange portion). The third step portion 107cc has the same shape as the flange portion when seen in a plan view, and houses the flange portion. The upper surface of the flange portion is not positioned above the upper surface 107 x of the second housing member 107.

  The third insertion hole 108c is provided with a claw 108ca. In this embodiment, there is only one claw 108ca, but a plurality of claws 108ca may be provided at a predetermined location. The claw 108ca is elastically movable. On the other hand, the lower part 123aa of the third light guide member 123 is provided with a protruding part 123ae on which the claw 108ca is hooked.

  When the lower portion 123aa of the third light guide member 123 is inserted into the third insertion hole 108c, the flange portion constituted by the light transmitting flange 123ac and the light shielding flange 123ba hits the lower surface of the third step portion 107cc, and The third light guide member 123 does not enter the third insertion hole 108c any more. At the same time, the claw 108ca is caught by the protruding portion 123ae. Accordingly, the third light guide member 123 is fixed in a state where the lower portion 123aa is inserted into the second housing member 107. The fixing method is not limited to such a method, and the lower portion 123aa of the third light guide member 123 may be fitted into the third insertion hole 108c. The flange portion may be fitted to the side surface of the stepped portion 107cc. Moreover, it is not necessary to fix in particular only by inserting like the 4th light guide member 124 mentioned later.

  The first light guide member 121 and the first insertion hole 108a also have the same configuration as the third light guide member 123 and the third insertion hole 108c, and the periphery of the first insertion hole 108a of the second housing member 107. Is provided with a first step portion (corresponding to the third step portion 107 cc) in which the flange portion of the first light guide member 121 is accommodated. For this reason, the 1st light guide member 121 will be fixed in the state where the lower part was inserted in the 2nd housing member 107 similarly to the 3rd light guide member 123. FIG.

  The fourth light guide member 124 and the fourth insertion hole 108d also have the same configuration as the third light guide member 123 and the third insertion hole 108c (in this embodiment, there is no fixation with a claw or the like). For example, the fourth light guide member 124 includes a light-transmitting portion 124a and a light-shielding portion 124b, and a flange portion configured by a light-transmitting flange portion of the light-transmitting portion 124a and a light-shielding flange portion of the light-shielding portion 124b. Is configured. In addition, a fourth step portion 107 cd that houses the flange portion of the fourth light guide member 124 is provided around the fourth insertion hole 108 d of the second housing member 107. Similarly to the third light guide member 123, the lower portion of the fourth light guide member 124 is inserted into the second housing member 107, and the fourth light guide member 124 is attached to the second housing member 107. . In this embodiment, the fourth light guide member 124 is not fixed to the second housing member 107, but the second light guide member 124 is arranged as described later, so that the fourth light guide member 124 Dropping from the second housing member 107 is prevented. The fourth light guide member 124 and the fourth insertion hole 108d may be configured to be fixed by a claw or the like as in the case of the third light guide member 123.

  The second light guide member 122 and the second insertion hole 108b also have the same configuration as the fourth light guide member 124 and the fourth insertion hole 108d, and the periphery of the second insertion hole 108b of the second housing member 107. Is provided with a second step portion (corresponding to the fourth step portion 107cd) in which the flange portion of the second light guide member 122 is accommodated. For this reason, the lower part of the second light guide member 122 is inserted into the second housing member 107, and the second light guide member 122 is attached to the second housing member 107, similarly to the fourth light guide member 124. It will be. As in the case of the fourth light guide member 124, a configuration in which the second light guide member 122 and the second insertion hole 108b are fixed by a claw or the like may be employed.

  Further, one or more third light sources 106c for illuminating the third light guide member 123 may be provided (here, two), but the third light source 106c is provided in the longitudinal direction of the third light guide member 123 (here, It is unevenly distributed at one end side (here, the left side that is the pointer-type instrument side) in the left-right direction. For this reason, the light receiving portion 123af of the third light guide member 123 is also located on one end side. The light receiving portion 123af is the lowermost surface (the surface closest to the circuit board 105) on the lowermost side of the third light guide member 123 (lower portion 123aa), and faces the third light source 106c.

  Light from the third light source 106c is received by the light receiving portion 123af, guided by the light transmitting portion 123a, and emitted from the upper end portion 123ad. That is, the upper end portion 123ad emits light. In the translucent part 123a, the inner surface (the inner surface of the lower part 123aa) that is the boundary between the translucent part 123a and the air and the inner surface (the inner surface of the upper part 123ab) that is the boundary between the translucent part 123a and the light shielding part 123b Light traveling through 123a is reflected. Through such reflection (internal reflection), the light transmitting portion 123a guides light. Here, since the third light source 106c is unevenly distributed on one end side, the light is emitted more from one end side (left side) of the upper end portion 123ad, and the light emission amount (that is, the closer to the other end side (right side)) The amount of emitted light) gradually decreases. For this reason, the upper end portion 123ad looks bright at one end side and shines in a light and dark gradation that becomes darker toward the other end side (the upper end portion 121ad and the second light guide of the first light guide member 121 in FIG. 2). (See the upper end 122ad of the member 122). In this embodiment, the one end and the other end are the one end and the other end in the longitudinal direction (left-right direction) of the third light guide member 123, respectively.

  In addition, when the translucent part 123a and the light-shielding part 123b which absorbs light are combined as a separate member like the past, an air layer etc. will be made between the translucent part 123a and the light-shielding part 123b. Due to this air layer, even if there is the light shielding portion 123b, the light traveling in the light transmitting portion 123a is totally reflected when it is internally reflected. In such a case, there is a case where the difference in the amount of light emitted between the one end side and the other end side is not large, and a sufficient gradation of light and darkness cannot be obtained for the upper end portion 123ad that emits light.

  In this embodiment, since the light transmitting portion 123a and the light shielding portion 123b that absorbs light are in close contact with each other, the inner surface (light shielding portion) of the light transmitting portion 123a serving as a boundary between the light transmitting portion 123a and the light shielding portion 123b. Part of the light (light reaching the light shielding part 123b) reaching the light shielding part 123b is absorbed by the light shielding part 123b and the remaining part is internally reflected (see FIG. 6, arrows in FIG. 6 are This represents a path of a part of the light emitted from the third light source). Thereby, when the upper end portion 123ad emits light, the upper end portion 123ad becomes darker as it approaches the other end side. For this reason, the difference in brightness of the gradation (the difference in brightness between the darkest part and the brightest part) is clearer than in the prior art (the difference in brightness becomes larger), and the gradation of light and dark is emphasized. This improves the design of the instrument device 10. It should be noted that ideally all of the light reaching the inner surface of the light transmitting portion 123a may be absorbed by the light shielding portion 123b. In this way, when the upper end portion 123ad emits light, the upper end portion 123ad becomes darker as it approaches the other end side. For this reason, the difference between light and dark gradations is clearer than before, and light and dark gradations are emphasized. Such a close contact configuration is particularly effective when the length of the third light guide member 123 in the longitudinal direction cannot be increased. Note that the light absorbed by the light shielding portion 123b may be visible light and may be light from the third light source 106c.

  In addition, the lower surface of the third light guide member 123 (lower portion 123aa) includes an inclined surface 123ag that is inclined with respect to the upper surface of the circuit board 105 in addition to the light receiving portion 123af (light receiving surface parallel to the upper surface of the circuit board 105). . The inclined surface 123ag is a surface connected to the light receiving portion 123af, and is a surface extending from the light receiving portion 123af toward the other end side (from the light receiving portion 123af to a predetermined location on the other end side than the light receiving portion 123af). The inclined surface 123ag is an inclined surface that is further away from the circuit board 105 toward the other end side from the light receiving portion 123af. The light reaching the inclined surface 123ag is easily reflected toward the one end side of the upper end portion 123ad, the one end side of the upper end portion 123ad becomes brighter, the difference between gradations is clear, and the gradation of light and dark Has come to be emphasized.

  It should be noted that the light from the third light source 106c on the circuit board 105 proceeds to the other end side and does not enter from the other end side of the lower surface of the third light guide member 123 (lower portion 123aa). A wall 99 that blocks light from the light may be provided (see the wall 99 drawn with a dotted line in FIG. 6). Accordingly, the other end side of the upper end portion 123ad is not unnecessarily brightened, the difference in gradation between the gradations becomes clearer, and the gradation between light and darkness is more emphasized. In addition, the said inclination part 123ag can make the said wall 99 high, and can suppress more effectively that the said other end side of the upper end part 123ad becomes unnecessarily bright.

  The first light guide member 121, the second light guide member 122, and the fourth light guide member 124 are similarly configured, and each upper end 121ad, upper end 122ad, and upper end 124ad are bright at one end side (the pointer 114 side). Emits light with a bright and dark gradation.

  The lower part 123aa of the third light guide member 123 is inserted into the third insertion hole 108c of the second casing member 107, passes through the third through hole 135c provided in the second symbol display board 132, and a part thereof. Projecting upward from the second symbol display board 132. The same applies to the first light guide member 121, the second light guide member 122, and the fourth light guide member 124. With such a configuration, the part for displaying the symbol 139 can be made three-dimensional, and the design of the instrument device 10 is improved.

  In particular, the third through-hole 135c is sandwiched between at least two symbols 139, so that the third light guide member 123 is in a position sandwiched between at least two symbols 139 (FIG. 2 and the like). The portion displaying the symbol 139 can be expressed in a three-dimensional shape by comparing the third light guide member 123 and the symbol 139 sandwiching the third light guide member 123, and the design of the instrument device 10 is improved. The same applies to the first light guide member 121, the second light guide member 122, and the fourth light guide member 124.

  Moreover, since the highest part (top part) of the upper end part 123ad of the third light guide member 123 is at a position higher than the highest part (top part) of the indicator part 129 in the vertical direction, the part for displaying the symbol 139 A three-dimensional feeling can be expressed more and the design of the instrument device 10 is improved. The same applies to the first light guide member 121. In addition, the highest part (top part) of the upper end part 123ad of the third light guide member 123 may be the same height as the highest part (top part) of the indicator part 129, and also by this, a three-dimensional effect is given to the part displaying the symbol 139. The design of the instrument device 10 is improved. In addition, the highest part (top part) of the upper end part 123ad of the third light guide member 123 is a part representing the number of the index part 129 (number representing the vehicle speed) (a flat plate part 129x inside the scale 129b of the index part 129). The height of the third light guide member 123 may be set so as to be higher or the same position. This can also express a stereoscopic effect.

  Further, the upper end portion 123ad of the third light guide member 123 may emit light in a predetermined color so that some information is notified to the user. For example, the control unit of the circuit board 105 may turn on the third light source 106c and cause the upper end 123ad to emit light when it is determined to notify the user of predetermined information based on a signal from the outside. The predetermined information may be notified by this light emission. For example, the control unit receives a signal indicating the amount of depression of the accelerator from the outside, and if the amount of depression indicated by this signal is less than a predetermined amount, the third light source 106c is used to notify that the current fuel consumption is good. May be turned on to light up the upper end 123ad. Note that the control unit normally emits the third light source 106c with a color (for example, white) other than the predetermined color (for example, green), thereby causing the upper end 123ad to emit light with the color, and notifies the predetermined information. In this case, the third light source 106c may emit light with the predetermined color. In such a case, the emission color may be changed by using the third light source 106c as a multi-color LED, or a third light source 106c that emits light in the predetermined color and a third light source 106c that emits light in other colors are prepared. Then, the third light source 106c that emits light may be switched. By using a three-dimensional object (such as one that can be easily noticed by the user) such as the third light guide member 123 for notifying the predetermined information, the user can easily focus on the predetermined information. 10 design is improved and functionality is improved. In particular, when the top portion of the upper end portion 123ad is higher than or at the same position as the highest portion (top portion) of the indicator portion 129, the user can easily pay attention to the light emission at the upper end portion 123ad. Improves and functionality improves. The same applies to the first light guide member 121, the second light guide member 122, and the fourth light guide member 124.

  Furthermore, since the upper end 123ad is different in height in the vertical direction depending on the location of the upper end 123ad (here, a part of the upper end 123ad is gradually lowered toward the one end side). A three-dimensional shape can be obtained for the part that displays the pattern 139, and the design of the instrument device 10 is improved. Since the third light guide member 123 is provided so that a part of the third light guide member 123 protrudes from the flat second symbol display board 132, the plane of the second symbol display board 132 is used as a reference to emphasize the change in height. Can be expressed. In addition, the third light guide member 123 is not only provided at a position with high visibility between the plurality of symbols 139, but also provided in a state of standing substantially perpendicular to this plane, so that the display space is small. However, the presence of light emission at a position closer to the user side than the second symbol display board 132 (for example, notification of predetermined information by light emission, etc.) is also possible. The same applies to the first light guide member 121, the second light guide member 122, and the fourth light guide member 124.

  Further, the third light guide member 123 is bent at the other end in a direction different from the longitudinal direction. This makes it difficult for the guided light to reach the other end side, and it becomes darker when the other end side is bent than when the other end side is straight, and the difference in gradation of the gradation becomes clearer. The same applies to the first light guide member 121, the second light guide member 122, and the fourth light guide member 124.

  Here, an outline of assembly of the instrument device 10 will be described. First, the second housing member 107 is attached to the first housing member 103 that houses the circuit board 105. Thereafter, the first to third liquid crystal display devices 111 to 113 are accommodated in the second casing member 107 in a state of being connected to the control unit of the circuit board 105. In addition, the pointer 114 is attached to the pointer shaft of the pointer driving unit 105 b that protrudes in front of the second casing member 107 through the through hole 107 a provided in the second casing member 107. Thereafter, the pointer liquid crystal display device 115 is stored in the space 107b in a state of being connected to the control unit. Then, the first to fourth light guide members 121 to 124 are attached to the second casing member 107. Further, the indicator portion 129 is disposed on the second housing member 107 so that the wall portion 107 c enters the recess on the rear side of the indicator portion 129.

  Thereafter, from above, the first symbol display board 131 is passed through the first light guide member 121 and the second light guide member 122 through the first through hole 135a and the second through hole 135b, respectively, and the upper surface 107x of the second housing member 107 is placed. Place on top. Further, from above, the second symbol display plate 132 is passed through the third light guide member 123 and the fourth light guide member 124 through the third through hole 135c and the fourth through hole 135d, respectively, and the upper surface 107x of the second housing member 107 is placed. Place on top. Finally, the turning member 141 to which the window member 143 is attached is fixed to the second housing member, and the instrument device 10 is completed.

  The first symbol display board 131 and the second symbol display board 132 move when the first symbol display board 131 and the second symbol display board 132 are sandwiched between the turning member 143 and the second casing member 107. Not to be fixed. Furthermore, part of the first symbol display board 131 and the second symbol display board 132 overlap the outer peripheral end of the indicator portion 129 from above, so that the indicator portion 129 can be prevented from being lifted. Moreover, a part (peripheral part of the 1st-4th through-holes 135a-135d) of the 1st symbol display board 131 and the 2nd symbol display board 132 is each flange part of the 1st-4th light guide members 121-124. Since they overlap from above, it is possible to prevent the second light guide member 122 and the fourth light guide member 124 from being lifted.

  Since the flange part of the 3rd light guide member 123 has light-shielding flange 123ba, it has light-shielding property. The flange portion is formed over the entire circumference of the third light guide member 123 and hits the second casing member 107 (specifically, the stepped portion 107cc). It is blocked by the flange. Accordingly, the amount of light leaking from the third insertion hole 108c (light from the third light source 106c) can be reduced (including the elimination). For this reason, the appearance around the third light guide member 123 can be improved. The same applies to the first light guide member 121, the second light guide member 122, and the fourth light guide member 124.

  Further, the flange portion of the third light guide member 123 enters under the peripheral portion of the third through hole 135c of the second symbol display board 132. Since this peripheral portion has a light shielding property, the amount of light leaking from the third insertion hole 108c (light from the third light source 106c) can be further reduced (including the elimination). In particular, the amount of light leaking from the translucent flange 123ac can be reduced (including the loss) by this peripheral portion. It should be noted that the joint between the third light guide member 123 and the second symbol display board 132 can be obtained by making the color of the upper surface of the flange portion and the color of the peripheral portion the same color, an approximate color, or a similar color. It is difficult and can improve the appearance of this part. The same applies to the first light guide member 121, the second light guide member 122, and the fourth light guide member 124.

(Modification)
The present invention is not limited to the above-described embodiment, and various modifications (including deletion of the configuration) may be made to the above-described embodiment. Hereinafter, although a modified example is described, at least a part of the following modified examples may be appropriately combined.

(Modification 1)
The upper end portion 123ad may be a portion that is part of the upper end side of the light transmitting portion 123a and is exposed from the light shielding portion 123b. Upper end part 123ad may consist only of upper surface 123ada of translucent part 123a. The upper end portion 123ad desirably includes at least the entire upper surface 123ada of the light transmitting portion 123a, but a part of the upper surface 123ada of the light transmitting portion 123a may be covered by the light shielding portion 123b. The portion 123ad is a portion other than the covered upper surface 123ada and is an exposed portion. The upper surface 123ada is a flat surface facing upward as in this embodiment, a flat surface facing upward, a convex surface protruding upward or diagonally upward, or upward or diagonally upward. It may be a concave surface that opens. The same applies to the first light guide member 121, the second light guide member 122, and the fourth light guide member 124.

(Modification 2)
The shape of each of the above members can be changed as appropriate. For example, the third light guide member 123 may not be bent. Further, the height of the upper end portion 123ad may be constant. The same applies to the first light guide member 121, the second light guide member 122, and the fourth light guide member 124. There may be one light guide member. The pointer 114, the indicator portion 129, and the like may also be configured to be illuminated by a predetermined light source provided on the circuit board 105. For example, the pointer 114 may be a light guide member, and light from a light source may be received so that a predetermined portion emits light. In addition, for example, a part of the indicator portion 129 (for example, the scale 129b) may be translucent and a light guide member may be provided in the indicator portion 129. In this case, the light guide member guides and emits light from the light source, and the emitted light passes through the translucent portion of the indicator portion 129. Thereby, the light-transmitting portion of the indicator portion 129 may emit light.

(Modification 3)
The 1st symbol display board 131 or the 2nd symbol display board 132 is flat form in said embodiment, However, An unevenness | corrugation may be provided by a drawing process. This increases the stereoscopic effect of the part displaying the symbol.

(Modification 4)
The first housing member 103 and the second housing member 107 may be one member instead of being separate members. The 2nd symbol display board 132 etc. may be arrange | positioned on the housing | casing member which combined the 1st housing member 103 and the 2nd housing member 107, and the 1st housing member 103 and the 2nd housing | casing may be sufficient as it. You may arrange | position on the housing member which made the member 107 one thing. The shape and the like of the housing member can be changed as appropriate. The 1st-5th light sources 106a-106e should just be arrange | positioned in these housing members.

(Modification 5)
For example, the third light guide member 123 includes an upper portion (in the above, for example, the upper portion 123ab and a light shielding portion 123b covering the side surface) and a lower portion (in the above, for example, the lower portion 123aa), and the upper end of the upper portion. Side surfaces (not all of the side surfaces other than the upper end portion) are shielded from light (in the above, for example, shielded by the light shielding portion 123b), and the lower portion (in the above, for example, the light reception of the lower portion). The surface 123af) receives light from a light source (for example, the third light source 106c in the above), and guides the received light upward inside (for example, the light is guided by internal reflection in the light transmitting portion 123a, for example). It is sufficient that the guided light is emitted from the upper end portion (for example, the upper end portion 123ad in the above).

  For example, the lower part of the light guide member is a housing member (in the above, for example, a combination of a first housing member and a second housing member that house the first to fifth light sources 106a to 106e inside). Is inserted into an insertion hole (for example, the third insertion hole 108c in the above), and the upper portion of the light guide member is a through hole provided in a symbol display board (for example, the second symbol display board 132 in the above). It only has to protrude upward from the symbol display board through (for example, the third through hole 135c in the above). In addition, the through hole includes at least a first symbol (for example, the symbol 139 on the ceiling side of the third light guide member 123 in the above) and a second symbol (for example, the third light guide in the above) provided on the symbol display board. The light guide member only needs to be disposed between at least the first symbol and the second symbol, as long as it is disposed between the symbol 139) on the ground side with respect to the member 123. For example, the height of the upper portion of the light guide member may be any height.

  For this reason, for example, the light-shielding part 123b only needs to expose the light-receiving part 123af and the upper end part 123ad (the case where only the light-receiving part 123af and the upper end part 123ad are exposed, and the case where the other part is exposed) The shape can be appropriately changed. The light shielding part 123b may cover at least a part of the part other than the light receiving part 123af of the lower part 123aa of the light transmitting part 123a. Moreover, it is not necessary to provide a flange part.

  In particular, as in the above-described embodiment, the upper portion (in the above example, the upper portion 123ab and the light shielding portion 123b that covers the side surface thereof) protrudes upward from the symbol display board (a portion that can be visually recognized by the user). By shielding all the side surfaces of the portion other than the upper end portion, for example, in the third light guide member 123, the side surfaces other than the upper end portion 123ad among the side surfaces protruding from the second symbol display board 132 Can be prevented from being emitted, and light emission from the upper end 123ad can be made conspicuous. You may light-shield only parts other than an upper end part among two main surfaces (side surface with a larger area) of the said protrusion part. It may be formed. Accordingly, the light emitting portion of the light guide member is linear from the side surface other than the main surface to the upper surface, so that the design of the instrument device 10 is improved.

  Further, when the light-transmitting portion 123a and the light-shielding portion 123b are used as in the above-described embodiment when the side surface is shielded from light, the light-transmitting portion 123a and the light-shielding portion 123b do not have to be in close contact with each other. It may be configured. Furthermore, the light shielding part 123b does not need to absorb the light guided by the light transmitting part 123a and reaching the light shielding part 123b. For example, the light shielding portion 123b may be a bright color such as white. The light shielding method may be painting or the like.

  The same applies to the first light guide member 121, the second light guide member 122, and the fourth light guide member 124.

(Modification 6)
For example, a light guide member such as the third light guide member 123 receives light from a light source (for example, the third light source 106c in the above) by a lower surface (for example, the light receiving unit 123af in the above) and guides the received light. The light emitted from the upper surface (for example, the upper surface 123ada of the upper end portion 123ad above), and the amount of light emitted from the upper surface decreases from the first position to the second position on the upper surface (the upper surface 123ada is in a gradation shape) As long as it emits light).

  Further, for example, the light guide member includes the lower surface and the upper surface, and transmits a light received by the lower surface and emits the light from the upper surface (for example, the light transmitting portion 123a in the above). And a light shielding portion (for example, the light shielding portion 123b in the above) provided on the side surface of the light transmissive member in a state where the upper surface and the lower surface are exposed, and the light shielding portion includes the light transmissive portion and the light transmissive portion. Any material that adheres and absorbs light that is guided by the light transmitting part and reaches the light shielding part may be used.

  For this reason, the light guide member does not have to partially protrude from the second symbol display board 132. The light guide member may be used for other uses or devices other than the instrument device 10. Moreover, the said light-shielding part does not need to be provided in all the side surfaces of the said translucent member. However, of the side surface of the portion of the translucent portion that is visible to the user (the portion that is visible when it is assumed that the light shielding portion 123b is not formed), the portion that is desired to emit light (for example, the upper end portion 123ad in the above). It is preferable to provide light-shielding portions for all portions other than the included side surfaces (for example, side surfaces in the vicinity of the upper surface, etc.) so that the unnecessary portions do not emit light. That is, the light-shielding part may be provided on a part other than the light-emitting part (a part including at least a part of the upper surface) to be lit among the parts visually recognized by the user. The state where the upper surface and the lower surface are exposed may be a state where at least a part of the upper surface and at least a part of the lower surface are exposed. In addition, two main surfaces (surfaces having a larger area) among the side surfaces of the portion of the light transmitting portion that is visually recognized by the user (the portion that is visually recognized when the light shielding portion 123b is not formed). The light shielding portion 123b may be formed so as to cover a portion other than the upper end portion of the light. Accordingly, the light emitting portion of the light guide member is linear from the side surface other than the main surface to the upper surface, so that the design of the instrument device 10 is improved.

  In the above embodiment, the first portion (the brightest part in gradation) is used as one end (one end in the longitudinal direction) of the upper surface 123ada, and the second part (the darkest part in gradation) is used as the upper surface. Although the other end of 123ada (the other end in the longitudinal direction) is used, the first location and the second location may be any location on the upper surface that emits light. For example, the first location may be the center of the upper surface 123ada, for example, and the second location may be one end or the other end of the upper surface 123ada. In such a case, the light receiving portion 123af is made to correspond to the first location and set to the center of the lower surface of the light transmitting portion 123a, and the third light source 106c may be opposed to the light receiving portion 123af at the center of the lower surface. The light receiving unit 123af may be at a position corresponding to the first location, for example, at a position below the first location. The inclined surface 123ag extends from the light receiving portion 123af at a position corresponding to the first location toward the portion corresponding to the second location (the portion located below the second location) on the lower surface of the light transmitting portion 123a. (It is not necessary to reach the portion corresponding to the second location.) And such an inclined surface 123ag becomes closer to the portion corresponding to the second location from the light receiving portion 123af. What is necessary is just to incline so that it may distance from the board | substrate 105. FIG.
