Figure 15 illustrates lighting device 24 parts as the mobile phone 20 of the band camera of an example of the picture pick-up device of the invention process form 14, and the component part same with above-mentioned form of implementation 1 adopts same-sign, omits its explanation.
That is, according to this form of implementation, the light of protective cover 25 and light emitting diode 31 pass through have the light diffusion sheet 40 that constitutes by the clear sheet that is used to make light scattering and film body etc. between light-distribution lens 33 on the path and the protective cover 25.Face at the object side that passes through the path of the light of light diffusion sheet 40 is formed with concaveconvex shape etc., forms the scattering surface 40a that light is carried out scattering, and the face of the light emitting diode that passes through the path 31 sides of light forms smooth even surface 40b.
Therefore, can obtain the effect same with form of implementation 1 in this form of implementation, and the light of the outside that enters by protective cover 25 is by the more light quantity of scattering surface 40a reflection of light diffusion sheet 40, remaining light quantity sees through light diffusion sheet 40.For this reason, Wai Bu light is also reduced by the light of reflections such as electronic circuit board 30.In addition, outside light is by electronic circuit board 30 reflections such as grade, the light of outside of mobile phone 20 that reflexes to the band camera is by scattering surface 40a scattering once more, so, when watching, the outside of mobile phone box body 21 is difficult to see inner light emitting diode 31 and electronic circuit board 30 etc.Therefore, in the occasion that light emitting diode 31 is turned off the light, also has the effect of the parts of the inside that is difficult to see effectively light emitting diode 31 grades from the outside.
On the other hand, in the occasion of light emitting diode 31 bright lamps, the light that penetrates from light emitting diode 31 the volume reflection of the even surface 40b of light diffusion sheet 40 with compare at the volume reflection of scattering surface 40a less, so, the good light quantity of subject supply relatively.
In this form of implementation, form at protective cover 25 and 33 structures of light-distribution lens, but also can be located between light-distribution lens 33 and the reflecting member 32 with light diffusion sheet 40.
In addition, the scattering surface 40a of light diffusion sheet 40 can consider to form on the surface a plurality of tiny concavo-convex occasions, form the occasion of a plurality of tiny convex lens shape, form the occasion of a plurality of tiny straight-line grooves, form the occasion of groove of the concentric circles of a plurality of tiny Fresnel lens shapes, in occasion of a plurality of tiny spherical transparent bodies of surface configuration etc.
Figure 16 illustrates the relation of image height with the illumination ratio of light diffusion sheet 40, image height by with the distance at center than expression, with the distance position farthest at the center of the image of shooting be image height 100%.For example, be the occasion of 4cm * 3cm in length and breadth what establish size of images as shown in Figure 17, center P is an image height 0%, and bight Q is an image height 100%, and Width pars intermedia bit position R is an image height 80%, and short transverse pars intermedia bit position S is an image height 60%.
In addition, illumination is than being represented by (illumination with scattering surface)/(illumination that does not have scattering surface).
The illumination at center can be kept higher when therefore, scattering surface 40a being located at the object side of light diffusion sheet 40.
On the other hand, in the occasion of scattering surface 40a being located at as light emitting diode 31 sides of light source side, the illumination at center descends bigger, but the decline of the illumination of periphery is less.Occasion scattering surface 40a being located at the both sides of light diffusion sheet 40 also can obtain the result same with this occasion.
Therefore, in lighting device 24,, can suppress the periphery illumination decline at center relatively effectively, at this moment,, descend thereby can suppress peripheral illumination effectively by scattering surface 40a being set in light emitting diode 31 sides as light source side by having light diffusion sheet 40.
Therefore, the structure that scattering surface 40a is located at the object side of light diffusion sheet 40 is shown in the above description, but also can as illustrating, the scattering surface 40a of light diffusion sheet 40 be located at the light emitting diode that passes through the path 31 sides of light by dot-and-dash line.
In this occasion, outside light when entering and reflex time both sides and above-mentioned similarly by scattering surface 40a scattering, so, in the occasion that light emitting diode 31 is turned off the light, have and make the difficult effect of seeing light emitting diode 31 internal parts such as grade from the outside effectively.
In addition, the illumination that can more effectively suppress periphery from the light of light emitting diode 31 descends, so, have the advantage that can carry out the photography of subject well.
In addition, even the occasion in the both sides of object side that scattering surface 40a is located at light diffusion sheet 40 and light emitting diode 31 also can obtain same advantage.
Therefore, scattering surface 40a etc. is set, suitably selects to get final product according to the performance and the specification of light-distribution lens 33 in which side of light diffusion sheet 40.
In addition, in above-mentioned form of implementation 2～form of implementation 13, can similarly be suitable for the light diffusion sheet 40 of such formation, can obtain same effect.
Form of implementation 15
Figure 18 illustrates lighting device 24 parts as the mobile phone 20 of the band camera of an example of the picture pick-up device of the invention process form 15, and the component part same with above-mentioned form of implementation 14 adopts same-sign, omits its explanation.
That is, according to this form of implementation, when carrying out scattering of light by light diffusion sheet 40, make the scattering of light angle peripheral part than near above-mentioned optical axis L more ninor feature become scattering surface 40a.
For example in form of implementation 14, the surface configuration of the scattering surface 40a of light diffusion sheet 40 is even, but in this form of implementation, from optical axis L towards peripheral part little by little or interimly change concaveconvex shape and form.In addition, in this form of implementation, the formation (by the shaping of macromolecular material etc.) of configuration by tiny spheroid or tiny convex lens shape also can form concaveconvex shape.In other formation, identical with form of implementation 14.
Therefore, according to this form of implementation, not only can obtain the effect same with form of implementation 14, and after reaching light diffusion sheet 40 from the light that light emitting diode 31 penetrates, scattering angle is big in the occasion of the scattering of light that the occasion of the scattering of light of middle body forms than the scattering surface 40a of the peripheral part of light diffusion sheet 40, reduces in the scattering of light amount of peripheral part, so, can reduce light scattering to the outer amount of image pickup scope, can increase the light quantity in the image pickup scope, can shine subject more brightly.

In this form of implementation, light-transmissive surface 42a lacks than the light transmission from light emitting diode 31 side direction object sides from the light transmission of subject side direction LED 31 sides.
Therefore, in this form of implementation, can obtain the effect same, and the light that enters by protective cover 25 from outside decay (dim light) by lamellar body 42 time is more with form of implementation 1., reduced by the light of reflections such as electronic circuit board 30, its reflected light does not inject to the outside of the mobile phone 20 of band camera basically for this reason yet.Therefore, when light emitting diode 31 is turned off the light, has the feasible effectively effect that is difficult for seeing light emitting diode 31 internal parts such as grade from the outside.
On the other hand, in the occasion of light emitting diode 31 bright lamps, the light ratio that penetrates from light emitting diode 31 be can't help lamellar body 42 decay, so, good light quantity can be supplied to subject.
In this form of implementation, be formed on the structure that has lamellar body 42 between protective cover 25 and the light-distribution lens 33, but also can be located between light-distribution lens 33 and the reflecting member 32.In addition, a part that also can the face that above-mentioned light transmission is different be formed on the parts of lighting device 24.

Figure 23 illustrates lighting device 24 parts as the mobile phone 20 of the band camera of an example of the picture pick-up device of the invention process form 20, and the component part same with above-mentioned form of implementation 8 adopts same-sign, omits its explanation.
That is,, the reflector body 39 of form of implementation 8 is is directly installed and fixed light emitting diode 31 according to this form of implementation.
Therefore, according to this form of implementation, not only can obtain the effect same with form of implementation 8, and because the mutual position of light emitting diode 31 and reflector body 39 concerns predetermined fixed, so, the light emitting diode 31 in the time of can preventing mobile phone 20 assembling with camera effectively and the mutual offset of reflector body 39.
The installation of reflector body 39 relative light emitting diodes 31 adopts the proper methods such as occasion that cooperate fixing and bonding etc. and light emitting diode 31 one of carrying out to constitute by installation bracket or pin to get final product.
Form of implementation 21
Figure 24 illustrates lighting device 24 parts as the mobile phone 20 of the band camera of an example of the picture pick-up device of the invention process form 21, and the component part same with above-mentioned form of implementation 8 adopts same-sign, omits its explanation.
That is,, make the light emitting diode 31 of form of implementation 8 and reflector body 39 paired, dispose 2 groups right symmetrically according to this form of implementation.
Occasion in this form of implementation, the direction ground that becomes inwardly from the light of two light emitting diodes 31 relatively disposes two light emitting diodes 31 on electronic circuit board 30,31 of two light emitting diodes dispose reflector body 39 respectively so that each optical axis L towards shooting direction warpage.
Therefore, according to this form of implementation, not only can obtain the effect same, and can improve subject illumination by the employing of a plurality of light emitting diodes 31 with form of implementation 8.
In addition, dispose the right of light emitting diode 31 and reflector body 39 by arranging a plurality ofly, thereby can obtain the few illumination of unevenness in the optical axis L direction of light emitting diode 31.

Form of implementation 22
In above-mentioned form of implementation 14, illustrated to have the occasion on surface that a plurality of tiny spherical transparent spheroids is configured to the scattering surface 40a of light diffusion sheet 40.In addition, the scattering surface 40a that light diffusion sheet 40 has been described in above-mentioned form of implementation 14 is towards the occasion of object side with towards the relation of image height with the illumination ratio of the occasion of light source.
In the form of implementation 22 of following explanation, describe the structure of light diffusion sheet 40 in detail, the direction towards scattering surface 40a also is described in detail.
Figure 25, Figure 26, Figure 27, Figure 28 are the sectional view of formation that the light diffusion sheet 40 of the invention process form 22 is shown.The formation of the integral body of the mobile phone 1 of the band camera of this form of implementation 22 is also used Fig. 1 equally with other form of implementation.
The light diffusion sheet 40 of the invention process form 22 shown in Figure 25 is made of scattering surface 40a and even surface 40b, and scattering surface 40a is made of globular transparent ball 40c and cementing agent 40d.In addition, the part of globular transparent ball 40c is exposed from the surface of scattering surface 40a, so the surface of scattering surface 40a forms concavo-convex.The scattering of light effect of scattering surface 40a produces greatly by the refringence between air and globular transparent ball 40c.Therefore, globular transparent ball 40c exposes more from scattering surface 40a, and when the concavo-convex degree on surface increased, the area that globular transparent ball 40c contacts with air increased, so the scattering of light effect increases, and is difficult for watching light emitting diode 31.On the contrary, when, surface little when concavo-convex degree became more approaching level and smooth state, the area that globular transparent ball 40c contacts with air diminished, so the scattering of light effect reduces, watches light emitting diode 31 easily.
Use glass, acrylic resin, styrene resin, silicone resin etc., for example acrylic acid, vinyl cyanide, polyurethane, Polyvinylchloride, polystyrene, polyacrylonitrile, polyamide, silicone rubber etc. at globular transparent ball 40c.In addition, as its shape, except spheroid, also can consider cubic, needle-like, shaft-like, spindle shape, tabular, flakey, fibrous, but consider that scattering of light does the time spent, spherical bead is better, and is just spherical or near just spherical spherical ideal.This be because, form spherical occasion in shape, each spherical particle works as micro lens respectively, so the scattering of light effect increases.In addition, in order to obtain scattering of light effect and the feasible effect that is difficult for seeing as the light emitting diode of light source simultaneously, preferably mean grain size is at 1 μ m～50 μ m.
Cementing agent 40d can use acrylic resin, polyurethane, polyester, fluororesin, silicone resin, polyamidoimide, epoxy resin etc.The particle diameter of the thickness of cementing agent 40d and globular transparent ball 40c also has relation, but is preferably 1 μ m～30 μ m.
In addition, the even surface 40b as the base material of light diffusion sheet 40 uses acrylic resin, styrene resin, polycarbonate, polyvinyl chloride resin etc.The thickness of even surface 40b does not limit especially, but the considerations such as operation when making light diffusion sheet 40 are preferably about 50 μ m～200 μ m.
Figure 16 illustrates light diffusion sheet 40 as enforcement form 14 explanation scattering surface 40a be the occasion of object side and the image height that scattering surface 40a is the occasion of light source (reflecting member 32) side (%: transverse axis) with illumination than (%: the relation longitudinal axis).The solid line of Figure 16 illustrates scattering surface and sees through near transmissivity not too reduction central authorities of light diffusion sheet 40 at the emergent light of the occasion light emitting diode 31 of object side, but extremely reduces at peripheral part.On the contrary, Figure 16 to be shown in dotted line scattering surface lower near central authorities in the transmissivity that the emergent light of the occasion light emitting diode 31 of light source side sees through light diffusion sheet 40, extremely do not descend but compare with middle body also at peripheral part.
, for dynamic image is photographed, camera is moved for a long time, for this reason, camera moves needed electric power and also increases., in mobile phone, there is the requirement of slimming, miniaturization, so, the battery that is equipped on mobile phone also requires slim, small-sized, in addition, requires to reduce as much as possible number of batteries, so, be difficult to use the battery of camera special use, more with the occasion of the battery sharing battery of other electronic component-use.Yet this CB common battery also requires slimming, miniaturization certainly, so, be difficult to increase the capacity of battery.
Therefore, for the consumption electric power that the action that suppresses camera produces, exist and use the occasion that consumes the less camera of electric power.Yet, consume the little camera of electric power and have the low tendency of luminous sensitivity.On the other hand, use the light quantity of the illumination of light emitting diode to compare very little with the light quantity of the lamp that uses xenon pipe etc.Therefore, the occasion of carrying out the shooting of image when the low camera of luminous sensitivity and the little light emitting diode of light quantity, in order to ensure absolute light quantity, towards object side the scattering surface 40a of light diffusion sheet 40 is configured to the front of light emitting diode 31, can obtains preferable image in the time of can carrying out the photography of subject according to the distribution of illumination ratio such shown in the solid line of Figure 16 from the emergent light of lighting device 24.
So little camera of consumption electric power is compared the photography that rest image is more suitable for dynamic image.
On the other hand, do not increase the requirement that the performance of such camera improves, the designs such as sheet number that must increase the lens that are installed on camera for the ratio of the light quantity of the middle body that satisfies camera and the light quantity of peripheral part.Yet, in the mobile phone that requires slimming as described above, can not increase the camera integral body that comprises lens.Use the more camera of light quantity decline of such peripheral part, the scattering surface 40a of light diffusion sheet 40 is configured to the front of light emitting diode 31 towards object side, emergent light from lighting device 24 carries out the photography of subject according to the distribution of illumination ratio such shown in the solid line of Figure 16, and then the peripheral part of image becomes very dark than middle body.For fear of such phenomenon, there is the occasion of the high camera of usability luminous sensitivity.Even the camera that luminous sensitivity is high also can be made a video recording for little light quantity, so, to compare with absolute light quantity, the distribution of illumination ratio is more important.Therefore, in the occasion of using such camera, the scattering surface 40a of light diffusion sheet 40 is configured to the front of light emitting diode 31 towards light source side, when carrying out the photography of subject according to the distribution of illumination ratio such shown in the dotted line of Figure 16, can obtain preferable image from the emergent light of lighting device 24., there is the tendency that consumes the electric power increase in the camera that luminous sensitivity is high.Therefore, the camera that luminous sensitivity is high is compared the photography that dynamic image is more suitable for rest image.
Like this, the scattering surface 40a of light diffusion sheet 40 towards object side still towards light source side also can be not only according to the performance of such light-distribution lens of explanation in form of implementation 14 and specification but also select according to the specification of camera.Certainly, can omit light-distribution lens 33 according to the specifications and characteristics of camera.
The light diffusion sheet 40 of shown in Figure 26 form of implementation 22 is made of scattering surface 40a and even surface 40b, and scattering surface 40a is made of hollow globular transparent ball 40e and cementing agent 40d.The point different with Figure 25 is that the globular transparent ball 40e that constitutes scattering surface 40a has space segment in inside, becomes hollow shape.The globular transparent ball 40c of Figure 25 only contacts with air on the surface of scattering surface 40a, and the scattering of light effect only produces at scattering surface 40a.Yet, when using hollow globular transparent ball 40e shown in Figure 26, the refraction that between the inwall of hollow globular transparent ball 40e and spheroid volume inside part, also produces light, light scattering, so, the scattering of light effect is bigger than solid globular transparent ball 40c shown in Figure 25, so the scattering of light effect is bigger than scattering surface 40a shown in Figure 25.
In addition, the light diffusion sheet 40 of shown in Figure 27 form of implementation 22 is made of scattering surface 40a and even surface 40b, and scattering surface 40a is made of globular transparent ball 40f and cementing agent 40d.It is wavy concavo-convex that the point different with Figure 25 is that the surface that will be in the cementing agent 40d between globular transparent ball 40f forms.Like this surface of cementing agent 40d is formed wavyly when concavo-convex, cementing agent 40d also has the scattering of light effect, and the scattering of light effect of scattering surface 40a further increases.
In addition, the light diffusion sheet 40 of shown in Figure 28 form of implementation 22 is made of scattering surface 40a and even surface 40b, scattering surface 40a by globular transparent ball 40g, 40d, and bubble 40h constitute.Be that with the difference of Figure 25 bubble 40h is blended into scattering surface 40a.Refringence between bubble 40h and cementing agent 40d is bigger than the refractive index between globular transparent ball 40g and cementing agent 40d, so when bubble 40h was blended into scattering surface 40a, the scattering of light effect was bigger than the occasion that does not have bubble 40h.In addition,, also can add pigment for scattering process that strengthens the reflection of light generation rather than the scattering process that reflects generation, rather than bubble 40h.Pigment for example can use titanium dioxide, zinc paste, ceruse, barium sulphide, lime carbonate etc.In addition, also pigment can be joined globular transparent ball 40g.When sneaking into pigment, the optical transmission rate descends, but is difficult for seeing that the effect of light emitting diode 31 increases.
Illustrated in front globular transparent ball 40c, 40e, 40f, 40g from scattering surface 40a expose, the surface of scattering surface 40a forms concavo-convex occasion, but scattering surface 40a is formed concavo-convex globular transparent ball 40c, 40e, 40f, the 40g of being not limited to, also can form the surface of scattering surface 40a concavo-convex by cementing agent 40d.
Form of implementation 23
In above-mentioned form of implementation 22, describe in detail form of implementation 14 light diffusion sheet 40 structure and towards the direction of scattering surface 40a.In the form of implementation 23 of following explanation, the structure of the light diffusion sheet different with form of implementation 14 is described.
Figure 29 is the schematic illustration of the lighting device 24 of the invention process form 23.The integral body of the mobile phone 1 of the band camera of this form of implementation 23 constitutes also similarly uses Fig. 1 with other form of implementation.
The difference of form of implementation 23 and form of implementation 14 is the surface of scattering surface 45a of light diffusion sheet 45 of this form of implementation for concavo-convex, but is smooth state.That is, such as shown in figure 30, light diffusion sheet 45 is made of scattering surface 45a and even surface 45b, and scattering surface 45a is made of bubble or pigment 45c and cementing agent 45d.In above-mentioned form of implementation 22, the surface of scattering surface 40a forms concavo-convex, but in this form of implementation, bubble or pigment 45c are blended into the inside of scattering surface 45a, make the surface smoothing of scattering surface 45a.About other formation, identical with form of implementation 14.Can not be bubble or pigment 45c also, but hollow globular transparent ball is blended into scattering surface 45a.
Like this, bubble or pigment 45c are blended into scattering surface 45a, are difficult for seeing light emitting diode, and as guaranteeing optical transmission, then the surface of scattering surface 45a can not be concavo-convex also, but is smooth state.
Form of implementation 24
In above-mentioned form of implementation 23, the structure of the light diffusion sheet different with form of implementation 14 has been described.
In the form of implementation 24 of following explanation, further specify the structure of the light diffusion sheet different with form of implementation 14.
Figure 31 is the schematic illustration of the lighting device 24 of the invention process form 24.The integral body of the mobile phone 1 of the band camera of this form of implementation 24 constitutes also similarly uses Fig. 1 with other form of implementation.
Form of implementation 24 is that with the difference of form of implementation 23 light diffusion sheet 46 of this form of implementation only is made of base material.That is, such shown in figure 32, the surface of light diffusion sheet 46 forms concaveconvex shape, but as guaranteeing the scattering of light effect, then need not constitute light diffusion sheet 45 for such 2 layers by scattering surface 45a and even surface 45b like that by form of implementation 23.In addition, also can sneak into bubble or pigment 46a in the inside of base material 46b like that as shown in figure 33, be difficult for seeing light emitting diode 31.In addition, can not be bubble or pigment 46a also, but in light diffusion sheet 46, sneak into hollow globular transparent ball.In addition, sneak into like that bubble or pigment 46a, hollow globular transparent ball as shown in figure 33 in light diffusion sheet 46, as guaranteeing the scattering of light effect, also the surface of light diffusion sheet 46 also can be smooth state.
Like this surface of light diffusion sheet 46 is formed concavo-convex, can guarantee the occasion that scattering of light is used, or as sneak into bubble or pigment 46a in the inside of light diffusion sheet 46, be difficult for seeing light emitting diode 31, and can guarantee optical transmission, then do not need to constitute light diffusion sheet 46, can realize the simplification of constructing by 2 layers.
Also can adopt the structure of above-mentioned light diffusion sheet 40,45,46 at protective cover 25.In this occasion, protective cover 25 has been given play to the function of light diffusion sheet 40,45,46, so, can realize dual-purposeization, also light diffusion sheet 40,45,46 can be set.
Form of implementation 25
Figure 34 illustrates lighting device 24 parts as the mobile phone 20 of the band camera of an example of the picture pick-up device of the invention process form 25, and the component part same with above-mentioned form of implementation 1 adopts same-sign, omits its explanation.
That is, according to this form of implementation, relatively the structure that reflecting member 32 reflects the optical axis L warpage 90 degree ground of the light that penetrates from light emitting diode 31 in form of implementation 1 forms the structure that reflects by the angle warpage ground beyond 90 degree.
The mobile phone 20 of Fig. 1 has the box-like mobile phone box body 21 that constitutes lengthwise, but not necessarily leaves no choice but closely dispose as shown in Figure 1 Electrofax 23 and lighting device 24, also has the occasion that disposes Electrofax 23 and lighting device 24 with leaving.
In addition, the mobile phone 20 of Figure 35 has mobile phone box body 28, and this mobile phone box body 28 has hinge 28c in 2 central authorities that constitute box-like machine box body 28a and 28b, but doubling ground constitutes.
Under this structure, the state of opening not necessarily leaves no choice but make 2 box body 28a and 28b to become level, has the angle about 10 degree.
In the occasion of this structure, the configurable any parts of Electrofax 23 to box body 28a, 28b, hinge 28c, but lighting device 24 also not necessarily is limited to and is configured to box body 28a, the 28b identical with Electrofax 23.
In these occasions, when light vertically flexes into the electronic circuit board 30 of box body surface horizontal arrangement of mobile phone 20 of relative band camera, beyond the image pickup scope of illumination Electrofax 23.
For this reason, form the structure that the optical axis L that makes the light that penetrates from light emitting diode 31 with reflecting member 32 reflects towards the image pickup scope warpage of Electrofax 23.
The optical axis of light-distribution lens 33 as one man disposes with the optical axis L of reflection warpage, but as the image pickup scope of Electrofax 23 of can throwing light on, then do not need optical axis alignment especially, also can make the optical axis of light-distribution lens 33 electronic circuit board 30 that vertically aligns.
Figure 36 illustrates the structure that the optical axis L of the light that penetrates from light emitting diode 31 is reflected by prism 37 by the angle warpage beyond 90 degree.
Light-distribution lens 33 is integrated with prism 37, similarly dispose alignedly with Figure 34 with the optical axis L of light of reflection warpage, but as the image pickup scope of Electrofax 23 of can throwing light on, then also can adopt light-distribution lens 33 posture, wait other structure from the separation of capsule 31b (with reference to Figure 38).
Form of implementation 26
Figure 37 illustrates lighting device 24 parts as the mobile phone 20 of the band camera of an example of the picture pick-up device of the invention process form 26, and the component part same with above-mentioned form of implementation 1 adopts same-sign, omits its explanation.
That is,,, form the not structure of this light scattering part 25a according to this form of implementation though protective cover 25 inner face side have and make the inside light scattering part 25a of processing such as diamond cutting that has been difficult for the carrying out seen in form of implementation 1.
In this occasion, light emitting diode 31 is configured under the mobile phone box body 21, and outer light does not directly touch light emitting diode 31, and the periphery of light emitting diode 31 becomes darker environment.
In addition, be used to adopt slim formation, highly can be about 1mm with the light emitting diode 31 of the lighting device 24 of the mobile phone 20 of camera.
In this occasion, the part by reflecting member 32 appreciable light emitting diode 31 from the outside becomes very little scope.
Secretly and from the outside appreciable scope is very little around the light emitting diode 31, even the feasible light scattering part 25a that can't help blocks inside, also has the occasion of infringement outward appearance with exceeding.
In this occasion, can cancel the light scattering part 25a of protective cover 25, reduce the loss of the light that causes at the reflection of light of light scattering part 25a etc., can obtain more bright illumination device 24.
In this form of implementation, though light emitting diode 31 is configured to the downside of mobile phone box body 21, also can be such as shown in figure 37, print on the surface of protective cover 25, wait by sealing shading light part 25b is set, configurable to the downside that is difficult to see inner part.
Form of implementation 27
Figure 38 illustrates lighting device 24 parts as the mobile phone 20 of the band camera of an example of the picture pick-up device of the invention process form 27, and the component part same with above-mentioned form of implementation 2 adopts same-sign, omits its explanation.
That is, reflecting member 32 installs and fixes light emitting diode 31 in form of implementation 2, constitutes integratedly with light emitting diode 31, describes an example of its Construction integration in this form of implementation in detail.
As an example of above-mentioned Construction integration, have reflecting member 32 is configured to structure in the capsule 31b of light emitting diode 31.The light-emitting component 31a of Figure 38 is configured in the capsule 31b of light emitting diode 31, and is luminous at periphery.By capsule 31b inside this light is reflected, optically focused is to the opening portion 31c that has reflecting member 32.
In the occasion of this structure, the parts precision decision of the capsule 31b of light emitting diode 31 is pressed in the location of reflecting member 32 and light emitting diode 31, so, can be undertaken by good precision, can make light correctly towards predetermined direction warpage ground reflection.
In addition, reflecting member 32 can be configured to capsule 31b opening portion 31c near, so light is few to the amount beyond the reflecting member 32, can light be delivered in the image pickup scope by good efficiency.
For this reason, can the throw light on easier and more brightly image pickup scope of Electrofax 23.
In addition, can constitute reflecting member 32 and light emitting diode 31, so Miniaturizable has the advantage that can further realize with the miniaturization of mobile phone 20 by 1 parts.
Figure 39 forms light-distribution lens 33 with Figure 38 and is fixed to the capsule 31b of light emitting diode 31 and incorporate structure.
In this occasion, the mutual offset of three in the time of can preventing mobile phone 20 assembling with camera effectively.
In addition, owing to can constitute reflecting member 32 and light emitting diode 31, light-distribution lens 33, so Miniaturizable has the advantage that can realize with the further miniaturization of the mobile phone 20 of camera by 1 parts.

Figure 40 illustrates lighting device 24 parts as the mobile phone 20 of the band camera of an example of the picture pick-up device of the invention process form 28, and the component part same with above-mentioned form of implementation 1 adopts same-sign, omits its explanation.
That is,, electronic circuit board 30 is shown, but describes this electronic circuit board 30 in detail in form of implementation 1 according to this form of implementation.
As the electronic circuit board 30 of the inside of mobile phone 20, can consider the electronic circuit board of other parts such as electronic circuit board 30b, camera of electronic circuit board 30a, lighting device 24 usefulness of mobile phone self.
