BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device capable of enhancing the aesthetic appearance of the device by providing a self-illuminating surface on the outer surface of the device main body, and enhancing the convenience of operation by illuminating the operation surface of the device. Things.

2. Description of the Related Art In recent years, in video equipment, audio equipment, and the like,
A device that partially illuminates the device itself and enhances the beauty of the device has been proposed. Hereinafter, conventional electronic devices will be described. FIG. 16 is a configuration perspective view of a conventional electronic device. In FIG. 16, reference numeral 101 denotes an electronic device housing, on the front surface 101f of which an operation switch or the like (not shown) for a user to operate is configured. Protrusions 101t are provided on both left and right sides of the front surface 101f, and a self-illuminating surface 101j is formed inside each of the protrusions (that is, a surface in contact with the front surface). In FIG. 16, reference numeral 102 denotes an optical element made of a milky white synthetic resin (PMMA or the like), which has a trapezoidal shape with a recess on the upper side, and whose bottom surface is mainly the self-illuminating surface 101j. (In FIG. 16, only the optical element 102 on the self-illuminated surface on the left side is shown and the optical element on the right side is omitted in FIG. 16, but both have optical elements having the same configuration.) . FIG. 17 shows a schematic configuration diagram of an optical element and a light emitting element for emitting light from a self-illuminated surface. In FIG. 17, reference numeral 103 denotes a light emitting diode which is a light emitting element.
And the irradiation axis of the light emitting diode 103 is configured to be in the height direction of the trapezoid of the optical element 101 (in the figure, the self-illuminated surface 101j is described as being on the lower side). . The operation of the conventional electronic device configured as described above will be described below. First, when a user operates a power switch (not shown) and power is supplied to the electronic device, the light emitting diode 1 serving as an irradiation element is turned on.
03 also emits a light-emission current and lights up. The luminous flux due to this light emission is also incident on the optical element 102 and exits from the opposing bottom surface, the self-illuminating surface 101j, as if the self-illuminating surface 101j.
Appears to be emitting light. In this manner, the self-illuminated surfaces 101j on the left and right sides of the front surface of the device emit light, and illuminate the front surface of the device housing and operation switches and the like in the vicinity thereof. This has the effect of making the operator know the position and the like of the operation switch.

However, in the above-mentioned conventional configuration, the light flux of the light emitting diode cannot be averaged over the entire surface of the self-illuminating surface, and the central portion is bright, and becomes darker toward the upper and lower ends. There was a problem in point. In addition, because of the height of the trapezoidal optical element, the projecting portion of the housing becomes large, the effective area for arranging operation switches and the like on the front of the housing becomes relatively small, and the design flexibility of the operation switches is reduced. (Placement position, etc.) is reduced. An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide an electronic device configured to minimize variations in illuminance of a self-illuminating surface or to more effectively use a front surface of a housing.

In order to achieve this object, an electronic device according to the present invention is an electronic device having a self-illuminating surface that partially illuminates the housing itself or inside the housing through the housing. An optical element including a diffusion section for diffusing and guiding a light beam from an incident section and an optical element having a self-illuminating surface formed continuously with the diffusion section and emitting a light beam, so as to reduce uneven light emission on the self-illuminating surface. Has an adjustment missing part in the diffusion part. With this configuration, the emitted light flux transmits, refracts, and reflects depending on the angle at which it enters the adjustment lacking portion provided in the diffusion portion. Therefore, the configuration of the adjustment lacking portion in the diffusion portion can reduce light emission unevenness on the self-illuminated surface. Electronic equipment is obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is an electronic apparatus having a self-illuminating surface that partially illuminates the housing itself or the inside of the housing through the housing,

Since the luminous flux transmits, refracts, and reflects depending on the angle at which the emitted light flux enters the adjustment lacking portion provided in the diffusion portion, the configuration of the adjustment lacking portion in the diffusion portion reduces light emission unevenness on the self-illuminated surface. Has the effect of being able to The invention according to claim 2 is characterized in that, in addition to the above, the optical element includes a reflecting portion that reflects at least once before the light beam from the diffusing portion is emitted from the self-illuminating surface. By changing the direction of the luminous flux of the element, the position and direction of the self-illuminated surface can be freely designed. The invention according to claim 3 is characterized in that a light-shielding paint is applied to the outer periphery of the incident part and the other optical element of the self-illuminating surface, and the inner wall of the element that temporarily transmits the light flux transmitted through the inner surface of the optical element is formed. Even the transmitted light flux is reflected back into the element by the light-shielding paint on its outer periphery, and thus has the effect of reducing the attenuation of the light quantity. According to a fourth aspect of the present invention, the optical element has a sub-illumination surface that transmits a light beam from a part of the diffusion part to the outside of the optical element,
In addition, the movable portion of the electronic device is provided with a sub-light guide portion that approaches, comes into contact with, or separates from, the sub-illumination surface according to its movement, and is provided with a housing or inside of the electronic device. It has the effect of changing the way the light beam is emitted according to the movement of the component, and changing the self-illumination of the self-illuminating surface. According to a fifth aspect of the present invention, the adjustment lacking portion of the light emitting element has a hole shape, and an insertion member made of a light-shielding material, a reflective material, or a luminous material is inserted into the adjustment lacking portion. In particular, the insertion member inserted into the adjustment missing portion is a pin erected on an adjacent member adjacent to the light emitting element, or the adjacent member is made of synthetic resin, and the pin is an adjacent member. This is an ejector pin for resin inflow and release during molding, and the degree of light emission on the self-illuminated surface can be adjusted more easily. Hereinafter, embodiments of the present invention will be described with reference to the drawings. (Embodiment 1) FIG. 1 is a perspective view showing the structure of an electronic apparatus according to Embodiment 1 of the present invention. In FIG. 1, 1
Reference numeral denotes an electronic device housing, similar to that described with reference to FIG. 16 of the related art, and has an operation switch and the like for a user to operate on a front surface 1f. Protrusions 1t are provided on both left and right sides of the front surface 1f, and self-illuminated surfaces 1j are formed on the insides (that is, surfaces in contact with the front surface). An optical element 2 indicated by a wavy line in FIG. 1 is made of a milk-white synthetic resin (PMMA or the like) as described in the background art, has a trapezoidal shape with a recess on the upper side, and has the above-described base surface on its own. Illuminated surface 1j
As in FIG. 16, it is exposed to the front.
However, only the optical element 2 on the self-illuminated surface on the left side is described and the optical element on the right side is omitted, but there are optical elements having the same configuration on both sides. FIG. 2 shows a schematic configuration diagram of an optical element and a light emitting element for emitting light from a self-illuminating surface. In FIG. 2, reference numeral 3 denotes a light-emitting diode, which is a light-emitting element. The light-emitting diode 3 has an irradiation part in a depression 2k on the upper side surface of the optical element 2, and the irradiation axis of the light-emitting diode 3 is in the height direction of the trapezoid of the optical element 1. (In the figure, the self-illuminated surface 1j is described as being on the lower side.) The difference from the conventional optical element is that a plurality of adjustment holes 2h penetrating through the trapezoidal diffusion portion 2d are provided. The operation of the electronic device of the present embodiment configured as described above will be described below. First, when a user operates a power switch (not shown) and power is supplied to the electronic device, a light-emitting current flows through the light-emitting diode 3 as an irradiation element, and the light-emitting diode 3 is turned on. The luminous flux of this light emission is also incident on the optical element 2,
Light is emitted from the self-illuminated surface 1j which is the opposite bottom surface, and it appears as if the self-illuminated surface 1j is emitting light. in this case,
In the optical element 2, since a plurality of adjustment holes 2h are provided symmetrically on and near the irradiation axis of the light emitting diode, as shown in FIG. When incident at an angle larger than the critical angle, the amount of light reflected inside the hole wall and dispersed inside increases, and conversely, when incident at an angle smaller than the critical angle, the amount of light refracted and transmitted through the hole wall increases. The light passes through the air layer in the adjustment hole 2h and is incident again on the substantially opposing hole walls. Therefore, by optimizing the position design of the adjustment hole 2h, the amount of light is dispersed on the self-illuminated surface 1j, and substantially uniform light emission can be obtained over the front surface. As described above, according to the present embodiment, the self-illuminated surfaces 1 on the left and right sides of the front surface of the device are provided.
Since j emits light and illuminates the front surface of the device housing and operation switches (not shown), etc., which are adjacent thereto, a unique expression is created to enhance the aesthetic appearance of the device, and the position of the operation switches is known to the operator. In addition to the effects of the prior art, there is an effect that the light emission irradiation of the self-illuminated surface 1j can be made uniform by adjusting and optimizing the position of the adjustment hole 2h of the optical element 2 at the design stage. (Embodiment 2) FIG. 4 is a perspective view showing the configuration of an electronic device according to Embodiment 2 of the present invention, and FIG. 5 is a schematic configuration diagram of an optical element. 4 and 5, 11
Reference numeral denotes an electronic device housing, similar to that described in Embodiment 1, on the front surface 11f, an operation switch and the like for a user to operate are configured. Protrusions 11t are provided on both left and right sides of the front surface 11f, and a self-illuminating surface 11j is formed inside each of the protrusions (that is, a surface in contact with the front surface). In FIG. 4, reference numeral 12 denotes an optical element, which is a trapezoid having the depression 12k on the upper side as described above, and has a trapezoidal diffusion portion 1.
An adjustment hole 12h is provided in 2d. Reference numeral 12r denotes a reflector having a trapezoidal bottom surface inclined at approximately 45 °, and the above-described self-illuminated surface 11j is configured to face the reflector 12r, and the self-illuminated surface 11j is exposed to the front. (Note that
In FIG. 4, as in FIG. 1, only the optical element 12 on the self-illuminated surface on the left side is described and the optical element on the right side is omitted, but there are optical elements having the same configuration in both. Also,
In FIG. 5, the self-illuminated surface 11j is shown in the front. The operation of the electronic device of the present embodiment configured as described above will be described below. First, as described above, by turning on a light emitting diode (not shown) provided in the depression 12k of the optical element, the light flux of the light emitting diode is scattered in the trapezoidal diffusion part 12d by the adjustment hole in the diffusion part, and substantially. The light quantity becomes uniform and is incident on the reflection part 12r. Next, the reflecting part 12r having a surface inclined at approximately 45 ° changes the optical axis of the incident light by approximately 90 °, and the self-illuminated surface 1r.
1j and illuminate. As described above, according to the present embodiment, by adjusting and optimizing the position of the adjustment hole 12h at the design stage, the effect of the first embodiment that the light emission of the self-illuminated surface 11j can be made uniform can be obtained. Of course,
By reflecting a substantially uniform amount of light by the diffusion unit 12d by the reflection unit 12r, which is a configuration unique to the second embodiment,
Since the size of the optical element can be reduced in the axial direction orthogonal to the self-illuminating surface 11j, the protrusion 11t on the front surface of the electronic device can be made smaller, and accordingly, the surface on which the operation switches and the like are arranged can be made larger. (Embodiment 3) FIG. 6 is a perspective view showing a partial configuration of an electronic device according to Embodiment 3 of the present invention, and FIG. 7 is a schematic configuration diagram of an optical element. In FIG. 6, reference numeral 21 denotes an electronic device housing, similarly to those described in the first and second embodiments, on the front surface 21f, an operation switch or the like (not shown) for a user to operate is configured. There is a depression 21t slightly above the center of the front surface 21f and left and right, and a self-illuminating surface 21j is formed on each lower surface (that is, a surface facing upward) (the other surface of the depression 21t is incidentally). Figure 6
To form a gentle curved surface). FIG.
Numeral 22 indicated by a dashed line denotes an optical element, as shown in FIG. 7, which has a trapezoidal shape with the recess 22k on the upper side as described above, and an adjustment hole 22h in the trapezoidal diffusion portion 22d.
Is provided. 22r has a trapezoidal bottom surface of approximately 45
The self-illuminated surface 21j is formed on the upper surface, and the terminal reflective portion 22e coated with the white paint 22w is formed on the lower surface thereof. (In FIG. 6, the optical element 22 on the self-illuminated surface on the left side in FIG.
Only the optical elements on the right side are omitted, but there are optical elements having the same configuration. In FIG. 7, the self-illuminated surface 21j is illustrated as being on the front upper side). The operation of the electronic device of the present embodiment configured as described above will be described below. First, as described above, by turning on a light emitting diode (not shown) provided in the recess 22k of the optical element, the light flux of the light emitting diode is transmitted to the trapezoidal diffusion part 22d by the adjustment hole 22h in the diffusion part 22d.
The light is scattered inside, and is incident on the reflecting portion 22r with a substantially uniform light amount. Next, the reflecting portion 22 having a surface inclined at approximately 45 °
Due to r, the incident light changes its optical axis by approximately 90 ° and is incident on the self-illuminated surface 21j and the terminal reflecting portion 22e. Of these, the amount of light that has reached the terminal reflecting portion 22e is reflected toward the self-illuminated surface 21j, and is emitted from the self-illuminated surface 21j to be illuminated since the outside is coated with the white paint 22w. As described above, according to the present embodiment, by adjusting and optimizing the position of the adjustment hole at the design stage, the effect of the first embodiment that the light emission of the self-illuminated surface can be uniformed, In addition to the effect of the second embodiment in which the optical element can be made smaller in the axial direction orthogonal to the self-illuminating surface by reflecting the substantially equal amount of light by the reflector, the self-illuminating surface that illuminates with high efficiency Can be freely determined. (Embodiment 4) In Embodiment 3 described above, two sets of optical elements and light emitting diodes to be incident on the optical elements must be provided on the left and right. In the fourth embodiment, a case in which one light emitting diode illuminates two self-illuminated surfaces will be described. FIG. 9 is a perspective configuration diagram of an optical element of an electronic apparatus according to Embodiment 4 of the present invention. In FIG. 9, reference numeral 32 denotes an optical element, and the optical elements of the third embodiment as shown in FIG. 7 are arranged on the left and right to constitute a left diffusion section 32d and a right diffusion section 32e. A portion corresponding to the concave portion of the optical element 3 is replaced with a light guide portion 3 having a reflective surface at an end.
It is tied with 2g. The light guide section 32g has a light entrance section at a substantially central portion thereof, and a light emitting diode 3 serving as a light emitting element.
The light beam of No. 3 is sent from the center of the light guide 32g to the reflection surface at the end by the reflection surface which is distributed to the right and left by approximately 45 °, and each diffusion portion 3
2d and 32e. Then, as described in the third embodiment, the light flux is scattered and reflected in each diffusion portion, and emitted from the left and right self-illuminated surfaces 31j and 31i. As described above, in order to cause the left and right self-illuminated surfaces to emit light, the left and right optical element diffusion sections are connected by the light guide section to form one optical element.
With two light emitting elements, it is possible to emit light while suppressing uneven brightness on two self-illuminated surfaces. In addition, since the two self-illuminated surfaces are caused to emit light by one light-emitting element, the light quantity of the light-emitting element is divided into two, and the long light guide portion also affects the attenuation of the light quantity, so that the uneven brightness of each self-illuminated face can be eliminated. However, it cannot be denied that there is a disadvantage that the amount of emitted light is reduced. In order to solve this problem, the light emitting diode is changed to one with high brightness, or the light emitting current is made to flow much (of course, in consideration of the maximum rating and reliability of the element) to increase the light emitting amount. The shape of the isosceles trapezoid of the left and right diffusion parts is broken as shown in FIG. 10 (in the figure, the light guide part is connected to the obtuse part of a right triangle, in which the sides on the inner side of the trapezoid of each diffusion part are approximately right angles). There is also a configuration in which the length of the light guide portion is shortened by that amount to reduce the light amount attenuation of the light guide portion.
In this case, the adjustment hole for reducing the uneven brightness can be designed as an adjustment groove having a groove shape extending to the end as shown in the figure. (Embodiment 5) Next, an example of an electronic apparatus that effectively utilizes the light guide portion of the optical element of Embodiment 4 will be described as Embodiment 5. FIG. 12 is a perspective configuration diagram of an electronic apparatus according to the fifth embodiment, showing a state in which a tray 41s at the center is sandwiched by a depression 41t having an illuminated surface 41j and a lid is opened by linear skating. Reference numeral 0 denotes an optical disk placed on a tray. FIG. 11 shows the relationship between the tray and the optical element of the electronic apparatus according to the fourth embodiment.
It is. In FIG. 11, reference numeral 42 denotes an optical element, which has a structure in which diffusion portions 42d and 42e and self-illuminated surfaces 41j and 41i are provided on the left and right as in the fourth embodiment, in which a diffusion light guide 42g is connected therebetween. . The structural feature of the optical element of the present embodiment lies in the diffused light guide section 42g, in which the entire light guide section of the fourth embodiment is replaced by a trapezoidal diffused light guide section 42g. And the diffusion light guide section 42
g is cut out in a substantially triangular prism shape, and the light guide illumination unit 42 is cut out.
k. Diffuse light guide section 4 other than light guide illumination section 42k
2 g of white paint 44 w is configured to prevent the internal light flux from leaking out. Reference numeral 44 denotes an auxiliary light guide element, which has a substantially triangular prism shape and is provided on a tray 41s (shown by a broken line in FIG. 11; an optical disk 0 on the tray 41s is shown by a dashed line) for linear skating. 41s abuts or approaches the light guide illumination unit 42k with the lid completely closed. The operation of the thus configured electronic device of the fifth embodiment will be described with reference to the drawings. As is well known, the tray 41s is translated by a linear skating mechanism (not shown). When the tray 41s is completely closed, as shown in FIG. 13A, the sub light guide element 44 abuts or approaches the light guide illumination section 42k of the optical element 42, and the light guide of the fourth embodiment as a whole is obtained. Work like a club,
The amount of light emitted from the light emitting element (not shown) at the center of the diffusion light guide 42g is diffused to the respective diffusion portions and the self-illuminated surface via the end of the diffusion light guide 42g. Next, when the tray 41s is about to be opened, the auxiliary light guide element 44 is
s and move in parallel, separating the light guide illumination unit 42k. For this reason, the light flux in the diffused light guide unit 42g leaks from the light guide illumination unit 42k before reaching the end of the diffused light guide unit 42g. Since this leaked light beam illuminates the tray 41s, it serves as illumination for confirming the presence or absence of the optical disc 0 on the tray 41s or for confirming the label of the optical disc 0. In this case, each self-illuminated surface is darker than when the tray 41s is closed, but since the tray on the center of each self-illuminated surface is brightly illuminated, the aesthetic feeling of the electronic device as a whole varies between when the lid is opened and when the lid is closed. This also produces the effect. In particular, as is well known, when the tray is closed or opened, the control electronic circuit unit (not shown) of the electronic device detects by the above-described linear skating mechanism. It is also possible to change the amount of light emitted from the light emitting element or to change the light emitting color of the light emitting element (it can be easily changed with a two-color light emitting diode such as green / red, as is well known).
As described above, according to the present embodiment, not only the effects of the above-described embodiments, but also a part of the light guide portion is cut and moved, and when the lid is closed, the cut portion is brought close to or in contact with the light guide portion. By doing so, there is an effect that the light guide portion can be closed, and a completely different portion can be self-illuminated from the cutout portion during the movement when the lid is opened. In the above-described fifth embodiment, the configuration has been described in which the auxiliary light guide element 44 blocks light flux leakage from the diffused light guide section 42g by approaching or abutting on the light guide illumination section 42k. The optical element may not be made of the same material as the optical element, and may be, for example, a light-shielding material or a reflective material that is close to or in contact with the light guide illumination unit. Specifically, instead of the triangular prism-shaped auxiliary light guide element described above, a so-called C is provided so as to abut or approach the light guide illumination portion of the tray.
Cut, and then apply gold or silver paint or gold or silver tape to the C-cut part (of course, both are not limited to gold and silver, but may be white, yellow, etc., light color). It can also be realized by a configuration that prevents or prevents light leakage and reflects light. (Embodiment 6) Next, an embodiment in which fine adjustment of the luminance can be performed without changing the design of the optical element, particularly the adjustment hole itself, using the above-described embodiment 1 will be described with reference to FIG.
4 and FIG. FIG. 14 is a partial cross-sectional view of the present embodiment showing the mounting of the optical element of the first embodiment, and shows a front panel (FIG. 14 shown in FIG. 14) which forms a housing of the front surface 1f of the electronic device 1 shown in FIG. (Shown as 1p) shows the inside of the housing of the protruding portion 1t. In FIG. 14, reference numeral 1q denotes an adjustment pin, which is configured to be aligned with the adjustment hole 2h of the optical element 2 on the inner surface of the protrusion 1t of the front panel 1p. In this case, the diameter and height of the adjustment pin 1q can be adjusted and designed in accordance with the degree of light emission of the self-illuminating surface only by designing so that the position of the adjustment hole 2h and the position of the adjustment pin 1q are substantially matched. . In particular,
When the front panel is made of synthetic resin, when ejecting the synthetic resin from the mold after molding, so-called ejector pins are used when the synthetic resin flows in and when the mold is released. By doing the same, the depth setting of the ejector pin during the molding of the synthetic resin can be fine-tuned to adjust the degree of light emission on the self-illuminated surface, especially brightness unevenness, without drastically changing the mold of the front panel. it can. As described above, according to the present embodiment shown in FIG. 14, by forming the adjustment pin that fits into the adjustment hole in the housing of the electronic device, the condition of light emission from the self-illuminated surface that cannot be adjusted only by the adjustment hole is used. Can be changed. FIG. 15 is a partial cross-sectional view showing another example of the present embodiment. The front panel 51p of FIG. 14 has a front panel 51p without the adjustment pins 1q. 2 is inserted into the second adjustment hole 2h. Also in this case, as described above, the diameter of the adjustment hole 2h and the outer shape of the adjustment rod 5 do not always have to match. Further, the material of the adjusting rod 5 can be set separately from the front panel 51p. For example, the adjusting rod 5 may be made of not only a dark member having a light shielding property but also a light member such as white or a fluorescent member. In the drawing, the three adjustments are formed by completely different members. However, a member in which a plurality of adjustment rods are erected in accordance with the position of the adjustment hole 2h of the optical element 2 may be used. Thus, FIG.
According to the present embodiment, the member to be inserted into the adjustment hole 2h can be set separately from the front panel 51p, so that in addition to the effect of the adjustment pin, it is possible to design more freely and to emit light on the self-illuminated surface. There is an effect that the adjustment of can be made more finely. Although the present embodiment has been described with reference to the case of the optical element of the first embodiment, the present invention is not necessarily limited to this, and can be applied to the other embodiments 2 to 5. Needless to say. In addition, although the case where the adjustment pins are formed in the housing called the front panel has been described, there is no problem even if the adjustment pins are formed in other components adjacent to the optical element, particularly in the synthetic resin component. (Applied Development of Embodiment) In the above description, an example in which the self-illuminating surface is configured on the front surface of the housing of the electronic device has been described.
It is not necessarily limited to this, and it can be configured on another surface of the housing, for example, the side surface or the upper surface. In the present embodiment, a so-called stationary electronic device such as an optical disk device has been described.
V-apparatus, sub-note type personal computer, etc. can be applied. Further, if the housing is made of a transparent or translucent synthetic resin (so-called skeleton) or a metal plate punched (a large number of small through holes are formed) or the like and has a light transmitting property, the inside of the housing is A self-illuminating surface may be configured. Further, the number of adjustment holes of the optical element can be designed according to the degree of light emission of the self-illuminated surface, and is not limited to the number (for example, three) shown in each embodiment. The shape is not limited to the cylindrical shape, but may be another shape. Needless to say, the shapes of the adjustment pins and the adjustment rods are not limited to cylindrical shapes. Further, as shown in FIG. 7, the terminal reflection part 22e, and as shown in FIG. 13, the parts 22w and 42w in which only the parts other than the light guide illumination part 42k below the diffused light guide part 42g are painted white. Provided
The present invention is not necessarily limited to this, and a white paint may be applied to a portion excluding the concave portion where the light flux of the light emitting element is incident and the self-illuminated surface from which the scattered light beam is emitted, and in some cases, an adjustment hole for adjusting the scattering. For example, a white coating may be applied to a part of the inner wall of the adjustment missing part. In addition, the light emitting diode as the light emitting element is exemplified by a so-called shell-shaped external lead type as shown in the figure. However, the present invention is not necessarily limited to this. For example, a surface mount type light emitting diode may be used. An envelope (side view type with a lens) such as LN58 manufactured by Toshiba Corporation may be used. In particular, for example, when an envelope with a bidirectional lens such as LN159 manufactured by the company is used, a light guide portion or a diffused light guide portion as in Embodiments 4 and 5 is provided at the center of the light guide portion. The light-emitting element can be easily incident without using a configuration in which a reflective surface is provided. Further, the light emission color of the light emitting element is not limited to red, which is a representative color of a light emitting diode, but may be another color (die die, green, yellow, blue, white, etc.). In particular, as described in Embodiment 5, by making the light emitting element a so-called two-color light emitting diode, for example, the self-illuminated surface emits light in red when the power is on and green when the power is off (in standby). It goes without saying that you can also do things. In addition, if a white light-emitting element that has recently started to be mass-produced stably is used, the surrounding area of the element is covered with a transparent resin-colored synthetic resin lid-like member, so that the self-illuminated surface is covered. The emission color can be easily changed without depending on the change of the light emitting element. Further, in the optical element of each embodiment, as the portion where the light emitted from the optical element is incident, the shape of the concave portion has been described as a concave shape as shown in the drawings, but the present invention is not limited to this. Needless to say, the shape may be a shape or a “U” shape. In particular, depending on the shape of the light-emitting surface of the light-emitting element, the light-emitting element may have a configuration in which the light is incident in a planar shape without being particularly hollow.

As described above, the present invention transmits, refracts, and reflects the emitted light beam depending on the angle at which it enters the adjustment lacking portion provided in the diffusion portion.
