Below, use Fig. 2～a plurality of lens 3 of 6 explanations, imaging apparatus 6 and electric base 7, endoscope inner matters such as 8 with respect to the fixture construction of the inner peripheral surface 5n of front end hard part 5.
Fig. 2 is the cut-open view of front end hard part, adhesive linkage and the lens of the II-II line in Fig. 1, Fig. 3 is illustrated in the adhesive linkage of Fig. 2, the cut-open view of the state of combination in the interface of the outer peripheral face of the interface of the inner peripheral surface of resin material and front end hard part and resin material and lens of the bubble in the resin material.
And, Fig. 4 illustrates the outer peripheral face of the lens of Fig. 1 stereographic map of the structure of application of resin material partly, Fig. 5 is the cut-open view of front end hard part, adhesive linkage and the lens of the V-V line in Fig. 4, and Fig. 6 illustrates the cut-open view of front end hard part, adhesive linkage and lens that forms the structure of adhesive linkage by the local difference of the thickness that makes resin material.
In addition, the example of below enumerating the fixture construction of lens 3 illustrates that the endoscope inner matter is with respect to the fixture construction of the inner peripheral surface 5n of front end hard part 5.
As Fig. 2～shown in Figure 6, between the outer peripheral face 3g of the inner peripheral surface 5n of front end hard part 5 and lens 3, be provided with and clip the adhesive linkage that resin material and air form.
Particularly, as shown in Figure 2, be provided with adhesive linkage 15 between the outer peripheral face 3g of the inner peripheral surface 5n of front end hard part 5 and lens 3, this adhesive linkage 15 is fixed on the resin material 16 on the inner peripheral surface 5n of front end hard part 5 by the outer peripheral face 3g with lens 3 and the bubble 17 of sneaking in the resin material 16 constitutes.
In other words, accompany the structure of resin material 16 and air between the outer peripheral face 3g of the inner peripheral surface 5n that forms at front end hard part 5 by bubble 17 and lens 3.
In addition, resin material 16 by a kind of organic solvent class bonding agent of liquid, elastic adhesive, moment bonding agent, aqueous adhesive etc. constitute, perhaps constituted by hybrid epoxidized class bonding agent of two kinds of liquid etc.Certainly, resin material 16 also can be made of three kinds of materials more than the liquid.
And, under the situation that resin material 16 is made of a kind of bonding agent of liquid, stir and in resin material 16, produce bubble 17 by the bonding agent to a kind of liquid; Under the situation that resin material 16 is made of the bonding agent of two kinds of liquid, when mixing two kinds of liquid, use centrifugal separator etc. that two kinds of liquid low speed rotation are stirred two kinds of liquid on one side, thereby in resin material 16 generation bubble 17.
In addition, as shown in Figure 3, also can be at the interface of resin material 16 and the inner peripheral surface 5n of front end hard part 5 and the interface of resin material 16 and the outer peripheral face 3g of lens 3 be formed with air layer 18, this air layer 18 are a plurality of bubbles 17 of in resin material 16, floating towards each interface in conjunction with and form.In this case, accompany the structure of resin material 16 and air between the outer peripheral face 3g of the inner peripheral surface 5n that forms at front end hard part 5 by bubble 17 and air layer 18 and lens 3.
In addition, as mentioned above, when the surfaceness of the inner peripheral surface 5n of front end hard part 5 forms slightly, be more prone to produce air layer 18 at the interface of resin material 16 and inner peripheral surface 5n.
And, as the example different with Fig. 2, Fig. 3, as Fig. 4, shown in Figure 5, enumerate following structure: be coated with the area of application A and the uncoated regional B that this outer peripheral face 3g is fixed on the resin material 25 on the inner peripheral surface 5n of front end hard part 5 by the outer peripheral face 3g of lens 3 is arranged, thereby between the outer peripheral face 3g of the inner peripheral surface 5n of front end hard part 5 and lens 3, be provided with by the resin material 25 that is coated in the area of application A and be clipped in the adhesive linkage 21 that the air layer 26 among the uncoated regional B constitutes.In this case, accompany the structure of resin material 25 and air between the outer peripheral face 3g of the inner peripheral surface 5n that forms at front end hard part 5 by air layer 26 and lens 3.
And, as the structure that the area of application A and uncoated regional B are set, preferred structure shown in Figure 11.Figure 11 is the stereographic map of lens of structure that the variation of Fig. 4 is shown.
In this structure shown in Figure 11, in the outer peripheral face 3g of lens 3, the complete cycle that spreads all over lens 3 respectively at front and the base end side of direction of insertion S is formed with the area of application A, simultaneously, in direction of insertion S, the mode that clips with coated regional A is formed with uncoated regional B, and at each the area of application A resin material 25 is set respectively, thus, air layer 26 maintains air-tight state by each resin material 25.Consequently, even if lens 3 are heated, because air layer 26 is compressed between the inner peripheral surface 5n of the outer peripheral face 3g of lens 3 and front-end architecture parts 5, therefore can further suppress the inclination of lens 3.
In addition, same with resin material 16, resin material 25 by a kind of organic solvent class bonding agent of liquid, elastic adhesive, moment bonding agent, aqueous adhesive etc. constitute, perhaps constituted by hybrid epoxidized class bonding agent of two kinds of liquid etc.Certainly, resin material 25 also can be made of three kinds of materials more than the liquid.
And, different with Fig. 2, Fig. 3, do not sneak into bubble 17 in the resin material 25 in this structure.Yet, in this structure, also can sneak into the resin material 16 of bubble 17 in the area of application A coating.
In addition, in this structure, because the uncoated regional B of resin material 25 is present between the outer peripheral face 3g of the inner peripheral surface 5n of front end hard part 5 and lens 3, therefore, compare with Fig. 2, structure shown in Figure 3, lens 3 descend with respect to the bonding strength of front end hard part 5, but, set enough intensity for as the intensity that lens 3 are fixed on the front end hard part 5, in addition, bonding with not using in the past, only by comparing against the structure that lens 3 are fixed on the front end hard part 5, have enough constant intensities.
In addition, as the example different with Fig. 2～Fig. 5, as shown in Figure 6, can list following structure: with respect to the outer peripheral face 3g of lens 3, the part coating ground of resin material 25 is thinner, be provided with the adhesive linkage 29 that is made of resin material 25 and air layer 27 thus between the outer peripheral face 3g of the inner peripheral surface 5n of front end hard part 5 and lens 3, described air layer 27 is formed by following space: apply than the thin space that forms, the interval between outer peripheral face 3g and the inner peripheral surface 5n by the part with this resin material 25.In this case, accompany the structure of resin material 25 and air between the outer peripheral face 3g of the inner peripheral surface 5n that forms at front end hard part 5 by air layer 27 and lens 3.
And, when lens 3 because heat and when being radially expanded, Fig. 2～bubble 17, air layer 18,26,27 of being clipped in the resin material 16,25 shown in Figure 6 makes resin material 16,25 easy plastic yield, can reduce lens 3 are given in the expansion that is accompanied by lens 3 from front end hard part 5 compression stress thus.
In addition, imaging apparatus 6, electric base 7,8 identical with respect to the fixture construction of the inner peripheral surface 5n of front end hard part 5 with respect to the fixture construction of the inner peripheral surface 5n also outer peripheral face 3g with above-mentioned lens 3.
That is, imaging apparatus 6, electric base 7,8 are bonded on the inner peripheral surface 5n via any adhesive linkage in the adhesive linkage 15,21,29.In addition, also can be that in lens 3, imaging apparatus 6, the electric base 7,8 at least one is bonded on the inner peripheral surface 5n via any adhesive linkage in the adhesive linkage 15,21,29.That is, do not need to make all endoscope inner matters all to be bonded on the inner peripheral surface 5n via any adhesive linkage in the adhesive linkage 15,21,29.
Showing the endoscope inner matter like this, in the present embodiment is fixed on the inner peripheral surface 5n of front end hard part 5 via any adhesive linkage that accompanies between the inner peripheral surface 5n of front end hard part 5 and lens 3, imaging apparatus 6, electric component 7, endoscope inner matters such as 8 in the adhesive linkage 15,21,29 that resin material and air form.
According to this situation, be delivered to the endoscope inner matter owing to being clipped in the luminous heat that produces that air in adhesive linkage 15,21, any adhesive linkage of 29 suppresses to be accompanied by light-emitting component 11 via front end hard part 5, so can suppress the thermal expansion of endoscope inner matter.
In addition, in the present embodiment, the inner peripheral surface 5n of front end hard part 5 forms has the face shape of heat sinking function, and front end hard part 5 is made of thermal conductivity ratio resin material 16,25 the high material of pyroconductivity, thus, even if the endoscope inner matter is heated, heat also can be discharged into other parts efficiently via front end hard part 5.
Therefore, be under the situation of a plurality of lens 3 at the endoscope inner matter for example, owing to can suppress the inclination of lens 3, therefore can prevent the birefringence that between lens and other lens, produces effectively, so imaging apparatus 6 can be taken high meticulous image.
And, be under the situation of imaging apparatus 6 at the endoscope inner matter, not only can prevent that imaging apparatus 6 from breaking down, and can be suppressed at the situation that produces noise in the image at the tested position of being taken by imaging apparatus 6.
In addition, be under electric base 7,8 the situation at the endoscope inner matter, in can being suppressed at substrate 7,8 electronic circuit, produce bad, the electronic unit that can also suppress to carry on substrate produces fault.
And, thereby in through hole 5k, be directly conducted to lens 3 lens 3 and be radially expanded even if for example be accompanied by heat that the driving of imaging apparatus 6 produces, by being clipped in the air in adhesive linkage 15,21, any adhesive linkage of 29, adhesive linkage 15,21, the 29 easy plastic yield that becomes, therefore the resin material 16 in the adhesive linkage, 25 is as padded coaming performance function, therefore, compare with the situation that in adhesive linkage, does not accompany air, can reduce the compression stress of giving lens 3 from front end hard part 5.
As mentioned above, can provide the endoscope 1 that possesses following structure: can suppress heat and conduct to the endoscope inner matter that is fixed on the front end hard part 5 via front end hard part 5 and can reduce the stress of giving the endoscope inner matter owing to the thermal expansion of endoscope inner matter from front end hard part 5.
In addition, variation below is shown.In the present embodiment, showing lens 3, imaging apparatus 6 and electric base 7,8 for example as the endoscope inner matter, but be not limited to this, also can be other parts.And the endoscope inner matter is not limited to the parts in the leading section 4 of insertion section 2, also can be the parts of inside at other positions of insertion section 2, also can be the parts in the operating portion.In this case, as the framework that keeps the endoscope inner matter, also can be the parts beyond the front end hard part 5.
And, show lens 3, imaging apparatus 6 and substrate 7,8 in the present embodiment and be fixed on the front end hard part 5, but be not limited to this, also can be separately fixed on the different frameworks.In addition, a plurality of lens 3 also can be separately fixed on the different frameworks.
In addition, below use the variation of Fig. 8 to describe.
Fig. 8 is the partial sectional view that summarily illustrates in the leading section of front of insertion section of endoscope of structure of variation of Fig. 1.
As shown in Figure 8, in the structure of the leading section 4 of the insertion section 2 of endoscope 1, also the lens 3 that are positioned at the front of direction of insertion S can be formed radially little than lens shown in Figure 13, and only in the mode of the inner peripheral surface 5n of the outer peripheral face 3g that buries lens 3 and distal end constituting part 5 resin material 16 is set in half part of the front of the direction of insertion S of the outer peripheral face 3g of the front of the direction of insertion S of lens 3.In addition, half part at the base end side of the direction of insertion S of outer peripheral face 3g is provided with air layer 107.According to this structure, can be easily in the insertion section 2 front keep watertight.
And, below use Fig. 9, Figure 10 that other variation is described.

As Fig. 9, shown in Figure 10, also can up to inner peripheral surface 5n through hole 300 be set from the outer peripheral face 5g of front end hard part 5.
If form this structure, owing to can inject resin material 16 from the through hole 300 on the outer peripheral face 5g that is located at front end hard part 5 towards inner peripheral surface 5n, therefore can operation well lens 3 be fixed on the front end hard part 5.
And the fixing means of lens 3 and front end hard part 5 is not limited to above-mentioned embodiment, and in the front end of front end hard part 5, side face 5n is provided with under the situation of structure of ladder difference within it, preferably constitutes resin material 16 in the following manner.That is, be located at an interarea of lens 3 and be located at air layer in the resin material 16 at the abutting part place between the ladder difference of inner peripheral surface 5n or the ratio of bubble is located at the side of lens 3 and the resin material 16 be located between the ladder difference of inner peripheral surface 5n is few.In this case, not only can carry out fixing between lens 3 and the front end hard part 5 more reliably, even and if the ladder difference portion of front end hard part is because external stress distortion, also can suppress influence that lens 3 are caused by air layer or bubble.
In addition, constitute front end hard part 5 by utilizing metallic glass, and the thermal expansivity of lens 3 and front end hard part 5 is approached, can access following effect.That is, the resin material 16 related according to present embodiment compared with the resin material that does not accompany air layer or bubble, and plastic yield takes place resin material 16 easily, therefore can further suppress the influence that lens 3 are caused.
