一般而言，光碟，例如 DVD媒體乃做爲貼合二枚之光碟基板而形成之貼合型之光碟加以形成。即，現在之 DVD媒體乃例如二枚貼合6mm厚之碟片基板加以形成，另一方面之下世代 DVD媒體中，則預定貼合二枚 0 , 1 m m厚和1。1 m m示之基板而形成。如此，貼合二枚之光碟基基板之手法乃例如揭示於曰本特開平〇 5 ·· 2 0 7 1 4號公報（專利文獻1 )。以下對於如此手法根據圖1乃至圖4加以說明。Generally, a compact disc, for example, a DVD medium, is formed as a bonded optical disc formed by bonding two optical disc substrates. That is, the current DVD media is formed, for example, by two substrates bonded to a 6 mm thick disk substrate. On the other hand, in the next generation DVD media, two substrates of 0, 1 mm thick and 1.1 mm are intended to be bonded. And formed. In this way, the method of bonding two optical disk base substrates is disclosed, for example, in Japanese Patent Application Laid-Open No. Hei. The following is described with reference to Fig. 1 through Fig. 4 for such a method.

如圖]及圖2所示，對向配置一對之旋轉平台]0 1、 1 02，對於此等之旋轉平台1 〇 1、1 02，經由真空吸附貼合之二枚之光碟基板1 〇 3、1 0 4加以固定而得地構成。下側之旋轉平台1 01乃經由馬達1 〇5，可旋轉驅動地加以構成，上側之旋轉平台1 〇 2乃經由上下機構1 0 6昇降自如地加以構成。然後，在於固定於上下之旋轉平台〗〇 1、1 02之二枚光碟基板1 〇 3 '] 0 4之間，經由旋塗機]0 7可供給黏著劑。旋塗機]07中·設有具有噴嘴]〇8之分配器]09, 此分配器]〇 9乃向該噴嘴]〇 8之前端部固定於旋轉平台 (2) 1264714 ]Ο ]、] 〇 2之二枚之光碟基板]〇 3、] 〇 4之半徑方向，可栘動自如地加以支持。旋塗機1 0 7乃如圖3所示，對於噴嘴1 〇 8供給黏著劑之黏著劑路徑ηο，和供給壓縮空氣之壓縮空氣路徑]η ，於分配器]0 9之正前方被統合而構成。黏著劑路徑u 〇乃經由收容於加壓槽1 1 2內之置入黏著劑之容器u 3、三方閥Π 4、過濾器1 1 5、球閥】丨6及針閥n 7到達空壓閥 1 1 8，在此與壓縮空氣路徑]〗〗統合。壓縮空氣路徑】j】乃壓封自；t氣之供給耢由電磁閥1】9到達空壓閥]1 8，，在此與黏著劑路徑1 1 0統合。由此’經由開啓黏著劑路徑Η 〇中之三方閥1丨4及壓縮空氣路徑1 1 1中之電磁閥丨丨9等，壓縮空氣則與黏著劑一同供給至分配器]0 9，黏著劑則從噴嘴1 0 8吐出。此時，經由調節空壓閥1 1 8，可改變供予分配器1 0 9之壓縮空氣之壓力，調節從噴嘴]〇 8吐出之黏著劑之量。做爲上述空壓閥1 1 8，使用電氣性可控制之電磁閥。使用如此構造之裝置，將貼合二枚之光碟基板103、 1 〇4之工程，，參照圖4地，如下地加以說明。在於固定於旋轉平台1 0 1、1 〇 2之二枚之光碟基板]0 3、1 0 4間，插入噴嘴〗〇8，將該前端部位於光碟基板]〇3之中央部附近。於此狀態，從噴嘴1 0 8吐出黏著劑，例如吐出紫外線硬化樹脂]2 0地，旋轉下側之旋轉平台]〇。結果，於下側 β光碟基板]0 3之中央部附近，紫外線硬化樹脂]2 〇則塗佈成圓周跃。（參照圖4Α)。冬 (3) 1264714 接著，經由上下機構】0 6，下降上側之旋轉平台i 〇 2 ’於下側之碟片基板]03，重合上側之碟片基板]〇4。（參照圖4 B) °然後’經由該馬達丨〇 5之驅動力，旋轉驅動下例之旋轉平13 ] 〇 ]，經由此連動旋轉上側之旋轉平台]〇 2 。結果’挾於二板之光碟基板]〇 3、1 〇 4之間的紫外線硬化樹脂]20則朝向外圍擴散（參照圖4C)。該擴展範圍到達規定之位置之時，停止旋轉平台]〇丨、丨〇2之旋轉。於此狀態下’紫外線硬化樹脂]2 〇所成黏著劑則待寸機到擴展至光碟基板1 0 3、1 〇 4之外圍端面。（參照圖4 D ) 。成爲圖4 D之狀態時，經由紫外線照射燈1 2 1，照射紫外線，硬化紫外線硬化樹脂1 2 0。由此，完成貼合二枚之光碟基板]〇3、104形成之貼合型之光碟122。圖5乃例示貼合型之光碟1 2 2的平面圖。圖6乃擴大位於該中央部之內周側透明範圍，將厚度變更顯示之縱剖側面圖。貼合型之光碟I 2 2乃包含佔據該面積之大部分的資訊範圍1 23，和位於中央部之內周側透明範圍]24。此內周側透明範圍1 2 4乃從形成於光碟1 2 2之中央部之中心孔1 2 5，到達資訊範圍1 2 3之範圍所生成之範圍，於其中，包含壓印溝範圍】2 6。此壓印溝範圍1 2 6乃經由於碟片基板1 0 3、1 0 4之製造時，必然生成之壓印溝]2 7 所形成之範圍。在此，列舉貼合型之光碟1 2 2之典型例之D V D媒體爲例，將各部之尺寸述於如下。DVD媒體中，外徑爲 I 2 〇 m m、板厚爲】.2 m m、中心孔]2 5乃]5 m m，壓印溝範 (4) 1264714 圍]2 6乃從中心形成於直徑2 2 m m附近。然後，例如紫外 $泉硬化树13θ ] 2 0所成之黏著劑乃以如下所述之形態存在。即’雖存在延展於二枚之碟片基板1 〇 3、] 〇 4之略整面的 ϋ V D媒體’但一般而言，乃延展於壓印溝範圍]2 6之前的位置，具有從壓印溝範圍1 2 6至先前之中心孔]2 5之位置則不存在黏著劑之空氣層1 2 8之情形爲多。然而，包含如此空氣層1 2 8之內周側透明範圍]2 4中，經由例如紫外線硬化樹脂1 2 0所成黏著劑之延展情形，會有產生外觀不佳之情形◦如此外觀之不佳乃非於DVD 媒體之資訊範圍1 2 3構成資訊本身之不佳者，而是單純外觀上之問題。但是，將D V D媒體做爲商品之時，該商品之價値會跌落。爲此，產生內周側透明範圍1 2 4之外觀不良的D V D媒體乃做爲不良品被加以處理。在此，做爲內周側透明範圍1 2 4之外觀不良之形態，有以下所述者°即，如圖5、圖6所示，黏著劑未到達目標位置之壓印溝範圍1 2 6之延展不足A、進入壓印溝範圍 ]2 6中之延展過多B、黏著劑有部分脫落之延展氣泡C等〇對於如此光碟1 2 2之內周側透明範圍1 2 4的外觀不良的有無，需進行光碟1 2 2完成後之檢查。就如此檢查方法而言，例如以人的眼睛視之加以確認者爲最方便。但是’ 光碟1 2 2之內周側透明範圍]2 4，以及延展於此內周側透明範圍1 24之紫外線硬化樹脂]20，一般而言爲透明的。結果，內周側透明範圍]2 4之外觀不良不易於由眼睛判斷 (5) 1264714 。在此，提案將光碟]2 2之內周側透明範圍]2 4，以攝像裝置，例如 CDD攝影機加以攝像，自動判定外觀不良的光碟檢查裝置。As shown in FIG. 2 and FIG. 2, a pair of rotating platforms] 0 1 and 1 02 are disposed opposite to each other, and for the rotating platforms 1 〇1 and 1 02, the two optical disk substrates 1 are attached via vacuum suction. 3, 1 0 4 is fixed and formed. The lower rotary table 101 is rotatably driven via a motor 1 〇 5, and the upper rotary table 1 〇 2 is configured to be freely movable up and down via the upper and lower mechanisms 160. Then, the adhesive is supplied between the two optical disk substrates 1 〇 3 '] 0 4 fixed to the upper and lower rotary stages 〇 1 and 1 02 via the spin coater 0 7 . In the spin coater] 07, a dispenser having a nozzle 〇8 is provided, and the distributor 〇9 is fixed to the rotary table at the front end of the nozzle 〇8 (2) 1264714 ] Ο ], 〇 2 of the two disc substrates] 〇3,] 半径4 in the radial direction, can be easily supported freely. The spin coater 107 is shown in FIG. 3, and the adhesive path ηο for supplying the adhesive to the nozzle 1 〇8 and the compressed air path ηη for supplying the compressed air are integrated in front of the distributor] Composition. The adhesive path u is passed through the container u 3, the three-way valve 4, the filter 1 15 , the ball valve 丨 6 and the needle valve n 7 placed in the pressure tank 1 1 2 to reach the air pressure valve. 1 1 8, here with the compressed air path]〗. Compressed air path] j] is the pressure seal from; t gas supply 耢 from the solenoid valve 1] 9 to the air pressure valve] 18, here integrated with the adhesive path 1 1 0. Thus, the compressed air is supplied to the dispenser together with the adhesive through the three-way valve 1丨4 in the open adhesive path 及 and the electromagnetic valve 丨丨9 in the compressed air path 1 1 1 , and the adhesive is applied. Then spit out from the nozzle 1 0 8. At this time, the pressure of the compressed air supplied to the distributor 109 can be changed by adjusting the air pressure valve 1 18, and the amount of the adhesive discharged from the nozzles 〇 8 can be adjusted. As the above air pressure valve 181, an electrically controllable solenoid valve is used. With the apparatus thus constructed, the construction of the two optical disc substrates 103 and 1 〇4 will be described below with reference to Fig. 4 . In the case of two optical disk substrates [0 3, 1 0 4] fixed to the rotating table 1 0 1 and 1 〇 2, the nozzle 〇 8 is inserted, and the front end portion is located near the central portion of the optical disk substrate 〇 3 . In this state, the adhesive is discharged from the nozzle 108, for example, the ultraviolet curable resin is discharged, and the lower rotating platform] 〇 is rotated. As a result, in the vicinity of the central portion of the lower side β-ray substrate]0 3 , the ultraviolet curable resin] 2 涂 is coated in a circular hop. (Refer to Figure 4Α). Winter (3) 1264714 Next, the upper and lower disc substrates "4" are superposed on the lower disc substrate [03] via the upper and lower mechanisms ○6, and the upper rotary table i 〇 2'. (Refer to Fig. 4B) ° Then, by the driving force of the motor 丨〇 5, the rotation flat of the following example is rotationally driven 13 ] , ], and the upper rotary table 〇 2 is rotated by this. As a result, the ultraviolet curable resin 20 between the optical disc substrates of the two sheets 〇 3 and 1 〇 4 spread toward the periphery (see Fig. 4C). When the extended range reaches the specified position, the rotation of the rotating platform 〇丨, 丨〇 2 is stopped. In this state, the "ultraviolet hardening resin" 2 〇 adhesive is to be extended to the peripheral end face of the optical disc substrate 1 0 3, 1 〇 4. (Refer to Figure 4 D). When the state shown in Fig. 4D is reached, the ultraviolet rays are irradiated via the ultraviolet irradiation lamp 112, and the ultraviolet curable resin 1200 is cured. As a result, the bonded optical disk 122 formed by bonding two optical disk substrates 〇3, 104 is completed. Fig. 5 is a plan view showing a photo-disc type 1 2 2 of a bonding type. Fig. 6 is a longitudinal sectional side view showing the thickness of the inner peripheral side of the central portion and the thickness of the central portion. The bonded type optical disc I 2 2 includes an information range 1 23 occupying most of the area, and an inner peripheral side transparent range 24 at the central portion. The inner peripheral side transparent range 1 2 4 is a range generated from a central hole 1 2 5 formed in a central portion of the optical disk 1 22, reaching a range of the information range 1 2 3, and includes an embossed groove range 2 6. The embossed groove range 1 2 6 is a range formed by the indentation groove 27 which is inevitably generated at the time of manufacture of the disc substrates 1 0 3 and 104. Here, a D V D medium of a typical example of a bonded optical disc 1 2 2 is taken as an example, and the dimensions of each part are described below. In DVD media, the outer diameter is I 2 〇mm, the plate thickness is .2 mm, the center hole is 2 5 is 5 mm, and the embossed groove (4) 1264714 is surrounded by 2 2 is formed from the center at a diameter of 2 2 Near mm. Then, an adhesive such as an ultraviolet ray hardened tree 13θ ] 20 is present in the form as described below. That is, there is a ϋVD medium that extends over the entire surface of the two disc substrates 1 〇 3, 〇 4, but in general, it extends beyond the embossed groove range 2 6 6 In the case where the groove range is 1 2 6 to the previous center hole] 2 5, there is a case where there is no air layer of the adhesive 1 2 8 . However, in the case where the inner peripheral side transparent range of the air layer 1 2 8 is in the form of an adhesive such as an ultraviolet curing resin 120, there is a case where the appearance is poor, and the appearance is not good. The information range of the DVD media 1 2 3 constitutes a poor person in the information itself, but a simple appearance problem. However, when D V D media is used as a commodity, the price of the product will fall. For this reason, the D V D medium which is inferior in appearance of the inner peripheral side transparent range 1 24 is treated as a defective product. Here, as an appearance in which the outer peripheral side transparent range 1 2 4 is defective in appearance, there are the following descriptions, that is, as shown in FIGS. 5 and 6, the embossed groove range in which the adhesive does not reach the target position is 1 2 6 The expansion is less than A, the range into the embossed groove] the extension of B in the 6 6 , the extended bubble C in which the adhesive is partially detached, etc. The appearance of the inner peripheral side transparent range 1 2 4 of such a disc 1 2 2 is defective or not , the inspection after the completion of the CD 1 2 2 is required. In terms of such an inspection method, it is most convenient to confirm it in the eyes of a person, for example. However, the 'transparent range of the inner circumference of the optical disk 12 2 2' and the ultraviolet curable resin 20 extending over the inner peripheral side of the transparent range 1 24 are generally transparent. As a result, the poor appearance of the inner peripheral side transparent range] 2 4 is not easily judged by the eyes (5) 1264714. Here, it is proposed to image the inside of the optical disk] 2 2 in the transparent range of the optical disk] 2 4 by an imaging device such as a CDD camera, and automatically determine the optical disk inspection device having a poor appearance.

圖7乃顯示如此光碟檢查裝置之一例的側面圖。於此光碟檢查裝置中，經由設於碟片支持台2 0]之中心柱2 0 2 ^定位檢查對象之光碟〗2 2。然後，由如此定位之光碟 ]2 2之正上方，以C D D攝影機2 0 3 ‘將該光碟1 2 2之內周側透明範圍1 2 4做爲檢查區域2 0 4加以攝像。此時，光碟 1 2 2之內周側透明範圍]2 4，及延展於此內周側透明範圍 1 24之紫外線硬化樹脂1 20的兩者爲透明，其等難以被區別。因此，將光碟1 2 2之內周側透明範圍]2 4以照明2 0 5 加以照射。然而，將光碟1 2 2之內周側透明範圍1 2 4由於接近鏡面之故，於C D D攝影機2 0 3之攝影影像中，照明2 0 5之虛像 2 0 5 a置入影像中。如此，於光碟]2 2之檢查區域Fig. 7 is a side view showing an example of such a disc inspection apparatus. In this disc inspection apparatus, the disc of the inspection object is positioned via the center post 2 0 2 ^ provided on the disc support table 20]. Then, from the CD 2 thus positioned, the C D D camera 2 0 3 'the inner circumference side transparent range 1 2 4 of the disc 1 2 2 is taken as the inspection area 2 0 4 and imaged. At this time, both the inner peripheral side transparent range of the optical disk 1 22 and the ultraviolet curable resin 1 20 extending over the inner peripheral side transparent range 1 24 are transparent, and it is difficult to distinguish them. Therefore, the inner peripheral side transparent range of the optical disk 1 2 2 is irradiated with illumination 2 0 5 .

As a result, the image output signal of the CDD camera 2 0 3 may become uneven. However, the optical disc inspection apparatus that automatically determines the appearance of the inner peripheral side transparent range of the optical disc] 2 2 is not disclosed in Japanese Laid-Open Patent Publication No. 1- 3 2 8 7 5 6 (Patent Document 2) and Japanese Special Open 2 0 0 0 - 1 6 2 ] 4 No. 7 (Patent Document 3). In the above-mentioned Japanese Patent Application Laid-Open No. Hei. No. Hei. No. Hei. No. Hei. No. 2 2,7,5,5,5,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, The brightness of the pixels is used to determine the poor adhesion of the adhesive. Further, in Japanese Patent Laid-Open Publication No. 2 (M62-47) (Patent Document 3), illumination of the optical disk is performed by illumination using a half-lens and a dome-shaped illumination, depending on the inner circumference of the imaging disk. In the image data obtained by the department, the invention of the optical disk inspection device is required to automatically determine the performance of the optical disk inspection device in the transparent range of the inner peripheral side of the optical disk. For the first time, a photographic image can be obtained for the inspection area. This is an indispensable feature for automatically determining the appearance of the transparent area on the inner circumference side of the optical disc. This will be disclosed in the aforementioned Japanese special Kaiping ^ 3 2 The device of the publication No. 8 7 5 No. 6 was tested as a result of the experiment by the inventor, and the difference in the presence or absence of the adhesive was not obtained. As a result, it was difficult to automatically determine the poor appearance of the transparent range on the inner circumference side of the optical disc. It is required to automatically determine other functions of the optical disc device outside the transparent range of the inner peripheral side of the optical disc, and to ensure that the working distance between the optical disc and the camera is also important. For example, when the operation of mounting the optical disc on the optical disc inspection device is performed by the robot hand buttocks, the movement space of the robot hand and the hip is required. In particular, the working distance between the optical disc and the imaging device is ensured to a certain extent. In the case where the optical disc of the two optical disc substrates illustrated in FIG. 1 and FIG. 2 is attached to the 'set optical disc', the inner peripheral side transparent range can be automatically determined to be -10 - (7) 1264714. For this reason, the working distance between the optical disk and the image pickup device is preferably 〇cm or more. This is disclosed in Japanese Laid-Open Patent Publication No. 2000-1996. In the construction of the semi-lens illumination optical disc, the height of the half lens is inevitably increased, so it is difficult to ensure the working distance between the optical disc and the imaging device to be more than 1 〇cm, or to ensure that the working distance is more than 10 cm. The overall height of the device as a whole will become higher, and the overall height of the device will increase and the size of the optical disc inspection device will be increased. Moreover, the optical disc device of the two optical disc substrates illustrated in the attached figure and FIG. 2 In the case where the structure of the inner peripheral side transparent range is poorly determined in the state in which the optical disc is set, it is not possible to apply the Japanese Patent Laid-Open No. 1- 3 2 8 7 5 6 which is disclosed in the illumination of the inspection area from the lower surface of the optical disc. The invention of Japanese Patent Laid-Open No. Hei. The object of the present invention is to provide an optical disc inspection apparatus that automatically determines the appearance defect of the inner peripheral side transparent range of the optical disc, and provides a working distance between a certain degree of the optical disc and the imaging apparatus that is imaged. And the overall configuration of the specific inspection area is uniformly illuminated. To achieve the above object, the invention of the scope of claim 4 is to use the inner peripheral side transparent range of the optical disc formed by bonding the two optical disc substrates as the inspection area' In the optical disc inspection device for the adhesion quality of the inspection area, there is a disc support table 'and a light source' for supporting the position of the optical disk of the inspection object, and a diffusion plate for diffusing the light irradiated from the light source, kh support The central axis of the aforementioned optical disc of the disc support table is matched with the 1264714 (8) optical axis to provide illumination from the diffusing plate. The inspection area of the optical disc is illuminated from the upper side into a ring-shaped annular illumination, and is arranged on the central axis of the optical disc supported by the disc support table, and is arranged with the optical axis, and the inspection area of the optical disc is photographed from above. The camera window will check the inner diameter S of the area, the outer diameter S 2 of the inspection area, the inner diameter L 1 of the ring illumination, the outer diameter L 2 of the illumination of the ring illumination, the ring illumination and the disc The distance LD and the positional relationship between the first principal point position Η 1 of the imaging device and the distance η D between the optical disks are S2 (l - LD/HD) < L1 < S 1 (1 + LD/HD ) L2> S2 (1 + LD/HD) Ground, set each part. By thus constituting the inspection area of the optical disc, the illumination light uniformly illuminated from the ring is illuminated, and the inspection area can be uniformly illuminated. As a result, it is possible to check the extension quality of the adhesive agent in the area of the high-precision inspection. Moreover, the working distance between the optical disc and the imaging device can be sufficiently ensured. The invention of claim 2 is a low reflection process in the range of the inspection area corresponding to at least the aforementioned optical disc in the disc inspection apparatus of claim 1 of the invention.糸f ώ jit _ )3⁄4 'The light reflectivity corresponding to the range of the disc inspection area of the disc support station will become lower. ' As a result, the light reflectance of the inspection area of the disc will decrease. 'The accuracy of the inspection area can be checked. The agent extends the quality. The invention of claim 3 is the optical disc inspection apparatus according to the first aspect of the patent application, wherein the aforementioned light source used for the aforementioned ring illumination is -12 - 1264714 (9) LED. As a result, the thickness of the ring illumination can be made thinner, and the working distance between the optical disc and the image pickup device can be ensured to be larger. In addition, the use of LED ring illumination, because of the high uniformity of brightness, can more evenly illuminate the inspection area of the disc. The invention of claim 4 is the optical disc inspection apparatus of claim 3, wherein the optical axis of the LED is directed toward the inner circumferential direction of the ring illumination. As a result, the size of the LED facing the direction of light irradiation from the ring illumination can be made smaller, and the thickness of the ring illumination can be made thinner. As a result, the working distance between the optical disc and the image pickup device can be ensured to be larger. The invention of claim 5 is the optical disc inspection apparatus according to the first aspect of the invention, wherein the light source used in the ring illumination is a curved fluorescent lamp. As a result, it is possible to use a cheap illumination to illuminate the inspection area as a whole evenly. The invention of claim 6 is the optical disc inspection apparatus according to the fifth aspect of the invention, wherein the image output signal for the image pickup device is provided, and a shading correction means for correcting the unevenness of the brightness of the ring illumination is performed. In the case of a fluorescent lamp that is bent into a ring, the brightness of the electrode portion is rapidly lowered, and the uniformity of illumination in the inspection area of the portion of the optical disk is lowered to cause unevenness, and the image formed by the image pickup device is uneven. In response to this, the shadow correction means is executed via the image output signal to the image pickup apparatus as described above. The same result as when the disc inspection area is uniformly illuminated can be obtained by 1264714 (10), and the adhesion quality of the inspection area can be checked with high precision. The invention of the seventh aspect of the patent application is the monitoring means for outputting the image output signal and display of the image pickup device to the display, as in the optical disk inspection device of the first application of the patent application. As a result, by viewing the display of the display, the adhesive spread quality of the inspection area of the optical disc can be observed, and the determination of the good linen can be facilitated. The invention of claim 8 is the optical disc inspection apparatus according to item 7 of the patent application, in which a signal is outputted from the image of the image pickup apparatus, and a black-and-white dimming method is applied to a certain threshold. The monitoring means outputs the signal to the display by outputting the image of the image. As a result, the image displayed on the display becomes a black-and-white image, whereby the adhesive spread quality of the inspection area of the disc can be seen at a glance, and the determination of the good work can be facilitated. The invention of claim 9 is a method of inspecting the inner peripheral side of the optical disc formed by bonding the two optical disc substrates, and inspecting the optical disc inspection method as the adhesive extending quality of the inspection region as the inspection region, a diffusing plate for dispersing the light source and the light irradiated from the light source, and supporting the ring on the central axis of the optical disk of the disk support table, and illuminating the light with the optical axis to illuminate the light from the diffusing plate The inspection area is illuminated from above into a ring-shaped illumination project, and the central axis of the optical disc supported by the disc support table is matched with the imaging device disposed on the optical axis, and the inspection area of the optical disc is photographed from above. Engineering: -14 - 1264714 (11) The inner diameter s of the inspection area, the outer diameter s of the inspection area, the inner diameter L of the illumination part of the aforementioned ring illumination, the outer diameter L2 of the illumination part of the aforementioned ring illumination, and the aforementioned ring illumination The positional relationship between the distance LD between the optical disc and the first principal point position Η 1 of the imaging device and the distance HD between the optical discs becomes S2 (l-LD/HD) < LKSl (i+LD/HD) ) L 2>S2(1+LD/HD) Set each part. As a result, in the entire inspection area of the optical disc, the uniform illumination by the annular illumination is illuminated, and the inspection area is uniformly illuminated. Thereby, the spread quality of the adhesive in the inspection area is checked with high quality. Moreover, the working distance between the optical disc and the image pickup device can be sufficiently ensured. The invention of the invention is to disclose the inner peripheral side transparent range of the optical disc formed by the two optical disc substrates, and to check the optical disc inspection method of the adhesive extending quality of the inspection area as the inspection area. In the case of the project of supporting the optical disk of the inspection object on the position of the disk support table, and the diffusion plate for arranging the diffused light source and the light irradiated from the light source, the support is described in the section of the wood chip. The central axis of the optical disc, the lighting of the ring arranged with the optical axis is used to illuminate the inspection area of the optical disc from the above, and to illuminate the inspection area of the optical disc into a ring, and bend the f! a concave shape, which is related to the inner diameter of the illumination portion of the ring illumination, which is generated by the diameter of the shadow on the inner diameter side of the inspection region of the optical disk, thereby removing the shadow from the inner diameter side of the inspection region of the optical disk. -15 - (12) 1264714 and the central axis of the aforementioned optical disc supported by the above-mentioned disc support table, with the imaging device configured with the optical axis, the inspection area of the optical disc is from above The project of photography,

結果1於光碟之檢查區域內徑側，未照入由環狀照明之照射光，於此範圍即使產生陰影，經由將光碟彎曲成凹狀，可縮小陰影，由此可將此陰影從前述光碟之檢查區域內徑側除去。因此，對於光碟之檢查區域內徑側，黏著劑之延展品質可被高品質地檢查。如申請專利範圍第]0項之光碟之製造方法之發明乃經由在固定於旋轉平台之第1之光碟基板上，吐出黏著劑之工程，和於前述第1之光碟基板上，重合第2之光碟基板之工程和旋轉驅動前述旋轉平台，延展前述二枚之光碟基板間之黏著劑之工程，As a result, on the inner diameter side of the inspection area of the optical disc, the illumination light by the ring illumination is not irradiated, and even if a shadow is generated in this range, the shadow can be reduced by bending the optical disk into a concave shape, thereby making the shadow from the aforementioned optical disc. The inner diameter side of the inspection area is removed.

Therefore, the inspection area of the optical disc formed by the optical disc forming process is uniformly illuminated by the illumination of the annular illumination, and the inspection area is uniformly illuminated. Further, the image output signal from the image pickup device becomes black and white. The portion where the adhesive is present is black, and the portion where the adhesive is not present is white, and the portion where the adhesive agent exists and the portion where the adhesive does not exist are clearly separated. Thereby, the image output signal corresponding to the inspection area is compared with the upper and lower thresholds. The spread quality of the adhesive in the inspection area is checked with high quality. Then, corresponding to the result of such determination, the progress of the inspection state is determined. Moreover, it can fully ensure the working distance between the optical disc and the camera. In the method of manufacturing the optical disc according to the seventh aspect of the invention, in the method of manufacturing the optical disc according to the seventh aspect of the invention, the method of determining the quality of the adhesive by the image output from the image pickup device is provided. As a result of the judgment of the work for determining the quality of the adhesive, the quality of the adhesive may be selected, and the selection of the optical disc generated by the defect may be selected.

In the optical disc, the adhesive spreading quality is characterized by using an optical disc inspection method as in any one of the claims 7-7 to 7 to check the adhesive extension quality. Therefore, it is possible to obtain an optical disc whose inspection quality of the adhesive in the inspection area is checked with high precision. The invention of the optical disc of the scope of the patent application is the transparent surface of the inner peripheral side of the optical disc formed by bonding the two optical disc substrates, and is used as an inspection area to check the adhesion quality of the optical disc in the inspection area. The spread quality of the agent is inspected using an optical disc inspection method according to any one of the claims 7 to 7 of the patent application, and the result of the inspection is selected from those in which the adhesive extension quality is not bad. Therefore, it is possible to obtain an optical disc whose inspection quality of the adhesive in the inspection area is checked with high precision. In the invention of the eighth aspect of the invention, the inner peripheral side transparent range of the optical disc formed by bonding the two optical disc substrates is used as an inspection area by the adhesive supplied from the spin coater, and the inspection area is checked. The optical disc inspection apparatus for extending the quality of the adhesive includes a disc support table for holding the optical disc of the inspection object in a stationary position, and a diffusion plate having a diffused light source and light irradiated by the light source; The central axis of the optical disc of the support station is configured to cooperate with the optical axis to illuminate the inspection area of the optical disc from the upper part into a ring-shaped ring illumination from the illumination light of the expansion board, and is supported by the disc support table.

Thus, the engineering of the ultraviolet resin which hardens and stretches the adhesive is carried out. In the above-mentioned various projects, two optical disc substrates, 〇3, 〇4, and the optical discs formed by the splicing type of the optical discs are formed, and the bonded optical discs are completed. In the apparatus illustrated in the above FIGS. 3 to 3, after stacking two optical disc substrates]03,]〇4, two optical disc substrates]03,1〇4, each holding -54 - (51) 1264714 In the state of the rotary table 1 0 1,] 0 2 , the lower rotating platform 110 is rotated, and the ultraviolet curable resin 120 is stretched. Therefore, it may be configured as another embodiment or as described below. That is, the second optical disk substrate 104 is applied to the first optical disk substrate 〇 3 on the lower side Z, and the second optical disk substrate 104 is laminated on the first optical disk substrate 1 〇 3 . Then, the first optical substrate 1 〇 4, from the rotating platform of the holder! 〇 9 Take out the state in this state, and rotationally drive the lower rotating platform 110, and extend the ultraviolet curable resin 1 2 0. In the present embodiment, at least one of the sheets is bonded to the sheet substrate 1〇3, 104, and the recording material of the film-forming phase change material is formed on the sheet surface, or the substrate is formed on the substrate. The surface has an anti-equal information support surface that forms a concave-convex memory. Then, the optical disk 1 22 having the structure of the optical disk substrates 1〇3, 1〇4 is formed such that the recording surface or the information support surface of the recording layer is formed, and the two optical disk substrates are bonded to the inner side. 04 was formed. Further, for the recording substrate or the optical disk substrate 1 0 3 or I 〇 4 having one of the information supporting surfaces, the recording layer or the information is formed also on the other optical disk substrate 10 4 or 1 〇 3 . Support for face construction is also possible. In such a case, a two-sided type optical disc 1 2 2 is formed. In contrast, on the other optical disk substrate 1 〇 4 or 1 〇 3, when the unformed recording layer is flattened with the information support surface, a single-sided type of optical disk is formed] 2 2 . Thus, the optical disc] 2 2 is formed, and the inner peripheral side transparent range 24 of the optical disc] 22 is used as the inspection area 3 〇 8, and the inspection of the adhesion extension quality of the inspection area 308 is performed. This project is illustrated as follows according to Figure 8 to Figure -55 - (52) 1264714 2 ]. Fig. 8 is a side view showing the optical disc inspection apparatus of the present embodiment for carrying out the above-described inspection project. The optical disc inspection apparatus of the present embodiment is basically the same as the configuration similar to the apparatus described with reference to Fig. 7, and instead of the illumination 2 0 5 , the ring illumination 3 0 is used. Figure 9 is an oblique view of the ring illumination 3 〇 1. Fig. 10 is a side view of the longitudinal section near the periphery of the illumination. Ring illumination 3 〇 ], for example, as shown in Fig. 9 and Fig. 1 , as a light source, a plurality of LEDs 3 0 2 are used. In other words, the diffusing plate 3〇3 which diffuses the light guided light is formed in a ring shape, and a plurality of LEDs 312 are disposed on the outer end surface of the diffusing plate 3 〇3. Then, on one surface of the diffusion plate 3〇3, all of the first reflection films 3〇4 covering the surface are formed, and in the other surface of the diffusion plate 300, the film is coated only with the second reflection film in the vicinity of the outer periphery. 3 0 5. Further, as the ring illumination 310, for example, the fluorescent lamp may be bent into a meander shape, and the diffusing plate may be used for coating. That is, the light irradiated by the light source as the ring illumination 3 0 1 ' is diffused on the diffusion plate, and has uniform light for operation %, and it is not necessary to inquire about the type. In the present embodiment, the ring illumination 301 shown in Fig. 8 is fixed to the CCD camera 203 via the illumination holder 306. Then, in the 'disc holding table 20', the upper surface illumination is not reflected, and the surface is subjected to "dull black" to be subjected to low reflection processing. Further, the central axis of the support disc 1 2 2 fixed to the disc support table 2 , ], and the central axis of the C C D camera 2 0 3 , and the central axis of the ring illumination 3 0 ] are all located on the same axis. In this way, when checking the disc 1 2 2, the actual rotation will check the object -56 - (53) 1264714 disc 1 22, on the disc support station 20]. When the positioning support works, and thus support the disc support The central axis of the optical disc i 2 2 of the table 2 0] is lit and the ring illumination 3 0 arranged in the optical axis is arranged, and the inspection area 3 0 8 of the optical disk 122 is turned from above by the illumination light of the diffusion plate 300. The project of the ring illumination, and the central axis of the optical disc 22 supported by the optical disc support table, the CCD camera 2 0 3 for the camera unit with the optical axis, and the inspection area 3 0 8 of the optical disc 1 2 2 The project above the camera. At this time, the ring illumination 3 0 1 is also the same as the illumination 2 0 5 illustrated in Fig. 7, and is reflected in the image of the image via the C C D camera 2 0 3 . However, according to the present embodiment, the reflection range 3 0 7 of the ring illumination 3 0 1 completely covers the inspection area 308. For this reason, a local image difference is not generated in the captured image via the C C D camera 2 0 3 , and a uniform image can be obtained. Thereby, the presence or absence of the adhesive in the inspection area 3 0 8 of the optical disk 1 2 2 can be surely detected. Here, in order to completely cover the entire area of the inspection area 308 of the optical disk 122, the ring illumination 301 is mapped, and the CCD camera or the ring illumination 301 or the like needs to be set to a specific positional relationship. The following 'for such a specific positional relationship will be described later. Let the inner diameter of the inspection area 308 be set to S1, and the inspection area of the inspection area 308 should be S2, and the inner diameter of the ring illumination 3 0 1 should be D1 and be reflected in the ring illumination 3 0 1 The inner diameter of the light-emitting portion with the diameter D 2 'ring illumination 3 〇 1 is L1, the outer diameter of the light-emitting portion of the ring illumination 3 0 1 is L 2 , and the distance between the lower end of the ring illumination 3 0 1 and the optical disk 122 is LD ' C CD camera When the distance between the first main position H] and the disc 1 2 2 is HD, the actual ring illumination 3 0 ], and the ring illumination 3 0 ], are reflected on the disc] 2 2 , and the generated virtual image 3 0 ] a has Similar off-57 - (54) 1264714 13⁄4. Thus, H D : D 1 - ( H D + L D ) : L 1 Η D : D 2 = ( H D + L D ) : L 2 . Thus, it can be expressed as L] 2 Dl(] + LD/HD) L 2 - D 2 ( 1 + L D / H D )

D 1 < SI 且， D2 > S2 被覆檢查區域 3 0 8的全面地，將環照明301，經由 CCD 攝影機2 03，可攝入攝像映像中。由此 L 1 < S 1 ( 1 + LD/HD) L2>S2(1+LD/HD) 成爲良好檢出黏著劑有無的條件。D 1 < SI and D2 > S2 covers the inspection area 308 in a comprehensive manner, and the ring illumination 301 can be taken into the imaging image via the CCD camera 203. Thus, L 1 < S 1 ( 1 + LD/HD) L2 > S2 (1 + LD / HD) is a condition for good detection of the presence or absence of the adhesive.

又，L 1過小之時，光碟1 2 2的檢查區域3 0 8之外周側的映像會無法攝像，爲此，L 1需設定爲某一程度。此 L 1的大/」、，可由下式求得。Further, when L 1 is too small, the image on the outer peripheral side of the inspection area 3 0 8 of the optical disc 1 2 2 cannot be imaged. Therefore, L 1 needs to be set to a certain extent. The large /" of this L 1 can be obtained by the following formula.

(HD - LD):L1= HD:SD LI > S2(l — LD/HD) 由此，成爲 S2(l - LD/HD)< Ll< Sl(l + LD/HD) -58 - (55) 1264714 由此，如第8圖所示構築檢查機構部3 5 ]。然後，根據如此構築檢查機構部3 5 ]，不僅完全被覆光碟]2 2之檢查區域3 0 8的全面地，可映入環照明3 0]，可充份確保光碟]2 2和C C D攝影機間的工作距離。然而，檢查黏著劑的延展品質之檢查區域3 0 8，係一般而言5內徑s 1爲]5 m m 5同樣地的外徑S 2爲4 0 m m程度。(HD - LD): L1 = HD: SD LI > S2 (l - LD/HD) Thus, it becomes S2(l - LD/HD) < Ll < Sl(l + LD/HD) -58 - ( 55) 1264714 Thereby, the inspection mechanism unit 35] is constructed as shown in Fig. 8. Then, according to the construction of the inspection mechanism unit 35], not only the entire inspection area 308 of the optical disc] 2 2 can be reflected in the ring illumination 30], but the optical disc can be fully secured between the CCD camera and the CCD camera. Working distance. However, the inspection area 3 0 8 for inspecting the ductility of the adhesive is generally such that the outer diameter S 2 of the 5 inner diameter s 1 is 5 m m 5 and the same outer diameter S 2 is 40 mm.

首先，畫像解析控制部5 0 1，係取出由 C C D攝影機 2 0 3的畫像輸出訊號，記憶保存於畫像記憶體4 0 6之同時，以記憶保存於檢查條件記憶部5 0 2之臨界値，黑白二値化該畫像輸出訊號，將二値化資料，記憶保存於二値化資料記憶部 5 0 3。此時，不存在黏著劑（紫外線硬化樹脂 1 2 0 )的範圍，係做爲白畫像資料表示，黏著劑（紫外線硬化樹脂1 20)存在的範圍，作爲黑畫像資料地顯示。然後，良窳判定部 5 04係參照記憶保存於二値化資料記憶部 5 0 3之二値化資料，判定光碟1 2 2的檢查區域3 0 8的良窳 (根據良窳判定手段，良窳判定工程，攝像裝置之C C D攝影機2 0 3的畫像輸出訊號，判定黏著劑延展品質的良窳之工程）。此時，良窳判定部 5 0 4，係根據記憶於檢查用參數値記憶部5 0 5之檢查用參數値，判定光碟1 2 2的檢查區域3 0 8的良窳。然後，良窳判定部5 0 4係僅將關於黏著劑的過度不足的檢查結果，記憶保存於檢查結果記憶部506 於此，對於環照明3 0 1，使用螢光燈亦可亦如前所述。但，使用螢光燈，構成環照明3 0 1時，無論如何於該電極部份，亮度會降低，產生亮度的不均同。因此，此時，爲解決如此的問題，例如於畫像解析控制部5 0 ]，對於由 C C D攝影機2 0 3的畫像輸出訊號，施行陰影補正，解除亮度的不均勻爲佳。 -61 - (58) 1264714 又，二値化資料記憶部5 Ο 3中，例如爲數張或數十張，所成光碟1 2 2的檢查時，記憶保存所採取複數次分的二値化資料。將此參照檢查條件設定變更部5 0 7，判定檢查狀態的推演（推演判定手段、推演判定工程）。例如，任複數次分的二値化資料，爲顯示不良品之資料，該傾向顯示相同的傾向時5可產生生產條件的變更或材料批次的變更所成變動。此時，記憶於檢查條件記憶部5 0 2，檢查條件則爲不適切。於此，例如，平均化記憶保存於二値化資料記憶部5 0 3之複數次分的二値化資料，對於該平均値所預測平均値超越某一臨界値時，檢查條件設定變更部5 0 7，將記憶保存於檢查條件記憶部5 02之檢查條件改寫。檢查條件記憶部5 02係如前所述，記憶保存爲白黑二値化由CCD攝影機203的畫像輸出訊號所使用的臨界値，除此之外，記憶保存環照明3 0 1的照度，CCD攝影機 2 0 3的快門速度，光圈，感度。如上所述，記憶保存於檢查條件記憶部5 0 2的檢查條件（爲白黑化使用由CCD攝影機2 0 3的畫像輸出訊號之臨界値，環照明3 0 1的照度， CCD攝影機2 0 3的快門速度，光圈，感度），經由檢查條件設定變更部5 0 7改寫時，由下回的檢查，畫像解析控制部5 01係以如此改寫檢查條件，實行檢查。檢查結果記憶部5 0 6中，例如數張或數十張所成，光碟〗2 2檢查時，記憶保存所採取複數回分的檢查結果。此時的記憶保存，係僅關於黏著劑（紫外線硬化樹脂]2 0 )的不足之檢查結果。沒有黏著劑（紫外線硬化樹脂]2 0 )的不 -62 - (59) 1264714 足時，該檢查結果，係沒有記憶保存於檢查結果記憶部 5 0 6。然後，將此檢查結果，參照旋塗機用的參數値設定變更部5 Q 8，例如，複數回分的檢查結果的平均値對於預測的平均値而言，超越某一臨界値時，旋塗改寫記憶保存於用參數記憶部 5 0 9之旋塗機用的參數値（設定値變更手段，設定値變更工程）。即，旋塗機用參數値記憶部5 0 9中，記憶保存關於旋塗機1 〇 7的黏著劑吐出量及黏著劑吐出位置之參數値，於旋塗機1 〇 7的驅動時，旋塗機控制部則 5 1 〇參照此等的參數値，驅動控制旋塗機1 07。因此，如上所述，將旋塗參數値寫入記憶保存於旋塗機用參數値記憶部5 0 9之旋塗機用參數時，變動旋塗機1 0 7的黏著劑吐出量及黏著劑吐出位置。更具體而言，於光碟1 22的檢查區域3 0 8，黏著劑（紫外線硬化樹脂1 2 0 )不足時，爲補足該不足的地方，增加旋塗機1 〇 7的黏著劑吐出量，或，移動旋塗機1 〇 7的黏著劑吐出位置。相反地，於光碟]2 2的檢查區域3 0 8，當黏著齊纟（紫外線硬化樹脂]20)過多時，解除該過多狀態地，減少旋塗機〗〇 7的黏著劑吐出量5或，移動旋塗機1 〇 7 的黏著劑吐出位置。此時，旋塗機1 〇 7的黏著劑吐出量的調節，係如以下所述實施。即，根據由微電腦4 04的控制訊號，經由控制器4 1 2的驅動控制，空壓弁]]8被控制，由此，可變化黏著劑（紫外線硬化樹脂]2 0)的吐出量，或·控制光碟基板 -63 - (60) 1264714 ]〇 3，] 0 4的旋轉速度。First, the image analysis control unit 501 extracts the image output signal from the CCD camera 203, and stores it in the image memory 460, and stores it in the threshold of the inspection condition storage unit 502. The black and white image is outputted by the image, and the data is stored in the binary data storage unit 503. In this case, the range in which the adhesive (ultraviolet-curing resin 1 2 0) is not present is shown as white image data, and the range in which the adhesive (ultraviolet hardening resin 1 20) exists is displayed as black image data. Then, the Liangzhu determination unit 504 refers to the data stored in the binary data storage unit 503, and determines the quality of the inspection area of the optical disk 1 2 2 (according to the Liangzhu determination means,窳 Judgment project, the image output signal of the CCD camera of the camera device, and the project to determine the quality of the adhesive extension). At this time, the good condition determination unit 504 determines the good condition of the inspection area 3 0 8 of the optical disk 1 2 2 based on the inspection parameter 记忆 stored in the inspection parameter 値 memory unit 505. Then, the Liangzhu determination unit 504 only stores the inspection result of the excessive shortage of the adhesive in the inspection result storage unit 506. For the ring illumination 301, the fluorescent lamp can also be used as before. Said. However, when a fluorescent lamp is used to form the ring illumination 3 0 1 , the brightness is lowered regardless of the electrode portion, and the brightness is not uniform. Therefore, in order to solve such a problem, for example, the image analysis control unit 50] performs shadow correction on the image output signal of the C C D camera 203, and it is preferable to cancel the unevenness of the brightness. -61 - (58) 1264714 In addition, in the data storage unit 5 Ο 3 of the data, for example, a few sheets or dozens of sheets, the inspection of the disc 1 2 2 is performed, and the memory is preserved by the pluralization of the plurality of points. data. This reference inspection condition setting change unit 507 determines the deduction of the inspection state (deduction determination means, derivation determination item). For example, if the data of the defective product is displayed for a plurality of times, the trend indicates that the same tendency 5 causes a change in the production conditions or a change in the material batch. At this time, it is stored in the inspection condition storage unit 502, and the inspection condition is unsuitable. Here, for example, the averaging memory is stored in the binary data of the plurality of times of the binary data storage unit 503, and when the average 値 predicted average 値 exceeds a certain threshold ,, the inspection condition setting change unit 5 0 7, the memory is stored in the inspection condition memory unit 052. The inspection conditions are rewritten. The inspection condition memory unit 052 is stored as a threshold 使用 used by the image output signal of the CCD camera 203 as described above, and the illuminance of the memory storage ring illumination 3 0 1 , CCD Camera 2 0 3 shutter speed, aperture, sensitivity. As described above, the memory is stored in the inspection condition storage unit 502. (The illuminance of the ring illumination 3 0 1 is used for the blackout of the image output signal of the CCD camera 203, CCD camera 2 0 3 When the inspection condition setting change unit 507 is rewritten by the inspection condition setting change unit, the image analysis control unit 510 performs the inspection by rewriting the inspection condition in this manner. In the inspection result storage unit 506, for example, a few sheets or tens of sheets are formed, and when the disc is checked, the result of the check is taken for the memory. At this time, the memory preservation is only the result of the deficiency of the adhesive (ultraviolet curing resin) 2 0 ). No adhesive (ultraviolet hardening resin) 2 0 ) No -62 - (59) 1264714 At the time of the test, the result of the test was not stored in the memory of the test result memory 5 5 6 . Then, the result of the inspection is referred to the parameter 变更 setting change unit 5 Q 8 for the spin coater. For example, the average value of the inspection results of the plural back points is overwritten by a certain threshold 値 for the predicted average 値The memory is stored in the parameter 値 (setting 値 change means, setting 値 change item) for the spin coater using the parameter memory unit 509. In other words, in the parameter 値 memory unit 509 of the spin coater, the parameter 値 regarding the amount of the adhesive discharge and the position at which the adhesive is discharged from the spin coater 1 记忆 7 is stored and stored, and when the spin coater 1 〇 7 is driven, the screw is rotated. The coater control unit drives the spin coater 1 07 with reference to the parameters 値. Therefore, as described above, when the spin coating parameter 値 is written and stored in the parameters of the spin coater for the spin coating machine parameter 値 memory unit 509, the amount of the adhesive discharge and the adhesive of the spin coater 1 0 7 are changed. Spit out position. More specifically, when the adhesive (the ultraviolet curable resin 1 2 0 ) is insufficient in the inspection region 030 of the optical disc 1 22, the amount of the adhesive discharge of the spin coater 1 〇 7 is increased to make up the shortage, or , the adhesive spin-off machine 1 〇 7 adhesive discharge position. On the other hand, when there is too much adhesion (UV curing resin) 20 in the inspection area 308 of the optical disk] 2 2, the excess state is released, and the amount of adhesive discharge 5 of the spin coater 减少 7 is reduced. Move the applicator discharge position of the spin coater 1 〇7. At this time, the adjustment of the amount of the adhesive discharge of the spin coater 1 〇 7 was carried out as follows. That is, according to the control signal of the microcomputer 404, the air pressure 弁]]8 is controlled via the drive control of the controller 4 1 2, whereby the discharge amount of the adhesive (ultraviolet hardening resin) 20) can be changed, or · Control the disc substrate -63 - (60) 1264714 ]〇3,] 0 4 rotation speed.

第]3圖係顯示記憶保存於檢查用參數値記憶部5 0 5 之檢查參數値的一例。如第1 3圖所不，作爲檢查用參數値t對於透過範圍最小面積邊緣數553，及集合數 5 5 4各自設定。於光碟]2 2的檢查區域3 0 8，黏著劑（紫外線硬化樹脂〗2 ())過多，乃將做爲透過範圍最小面積 5 5 1 設定値5與採取白畫像資料比較而加以判定。即，白畫像資料所顯示之面積，較作爲透過範圍最小面積5 5 1，所設定面積値少，黏著齊lj (紫外線硬化樹脂1 20)則過多。由此，黏著劑（紫外線硬化樹脂120)之不足，乃將作爲透過範圍最大面積5 5 2設定之面積値，經由與採取白畫像資料所顯示面積比較而加以判定。即，將採取白畫像資料顯示之面積値，較作爲透過範圍最大面積5 5 2，所設定値之大的話，黏著齊彳（紫外線硬化樹脂]2 0)會變得不足。The third drawing shows an example of the inspection parameter 记忆 stored in the inspection parameter 値 memory unit 505. As shown in Fig. 3, the inspection parameter 値t is set for each of the transmission area minimum area edge number 553 and the number of sets 5 5 4 . In the inspection area of the optical disc] 2 2, the adhesive (ultraviolet curing resin 〖2 ()) is too much, and it is determined as the minimum area of the transmission range 5 5 1 and 値5 is compared with the white image data. That is, the area displayed by the white image data is smaller than the area of the minimum area of the transmission range of 5 5 1, and the adhesion is lj (ultraviolet curing resin 1 20). Therefore, the shortage of the adhesive (ultraviolet-curing resin 120) is determined by comparing the area 设定 set as the maximum area of the transmission range 5 5 2 with the area displayed by taking the white image data. In other words, the area 値 of the white image data is smaller than the maximum area of the transmission range of 5 5 2, and if it is set to a large extent, the adhesion (ultraviolet curing resin) 20) becomes insufficient.

As shown in Fig. 14, the inspection parameter 値 is set for each of the non-transmission range minimum area 5 6 1, the non-transmission range maximum area 5 6 2 , the edge number 5 5 3 , and the number of sets 5 5 4 . In the inspection area 3 0 of the optical disk 122, the adhesive (ultraviolet-curing resin I 2 0 ) is insufficient, and the area is set as the minimum area of the non-transmission range of 5 6 1 , which is displayed by the black image data taken. Compare and judge. That is, (61) 1264714 The area of the black image data is smaller than the minimum area of the non-transmission range of 56], and the adhesive (ultraviolet curing resin) 20) becomes insufficient. Thus, the adhesive (ultraviolet hardening) Resin]2 0 ) is too much, and will be set in the non-transmission range maximum area of 562, and is judged by comparison with the black image data display area taken. In other words, if the black image data display area 値 is larger than the maximum area of the non-transmission range of 5 6 2 , the adhesive (ultraviolet curable resin 120) becomes excessive. Fig. 15 shows another example of the inspection parameter 记忆 stored in the inspection parameter 値 memory unit 505. As shown in Fig. 15, the inspection parameter 値 is set for each of the transmission range minimum area 551, the transmission area maximum area 5 5 2 , the edge number 5 5 3 , and the number of sets 5 5 4 . Then, for the maximum area of the transmission range of 5 5 2, the division into the A range 5 7 1 and the B range 5 7 2 is performed for each range. The determination of the excessive shortage of the adhesion (violet curing resin) 20 in the inspection area of the optical disk 122 at this time is the same as the case of the inspection parameter 例 exemplified in Fig. 3 . Fig. 16 shows a schematic diagram of another example of the parameter for inspection stored in the parameter for inspection 値 memory unit 505. In the example shown in Fig. 16, as the parameter for inspection, the minimum area of the non-transmission range is 5 6 1, the maximum area of the non-transmission range is 5 6 2, the number of edges is 5 5 3, and the number of sets is 5 5 4 . Then, for the non-transmission range minimum area 5 6 1, the range is divided into Α range 5 7 1 and B range 5 7 2, and each range is determined. At this time, in the inspection area of the optical disc] 2 2, the adhesive (ultraviolet hardening resin) 2 0 ) is judged to be insufficient by -65 ~ (62) 1264714 degrees, and the first J _ 1 is used as an inspection parameter: The case of 値 is the same as 0. For the 3rd, 4th, 5th, and 16th, the number of edges is 5 5 3 , the number of sets is 5 5 4 ^ A, 5 7] and Β range; 72 As described below, C first describes the number of edges 5 5 3 5 with reference to the 1 7 A 7 A to the 1 7 C chart. The 1 1C _ is illustrated on the inner peripheral side of the optical disc 1 22. The transparent range 1 2 4 Produces an adhesive (UV; line hardening resin 120: a pattern diagram of excessively insufficient state. The rectangular range in the figure is expanded to be the 17th B and the 1st 7th C. These 1 7 B and 1 7C The figure shows that each adhesive (UV-line hardening resin 120) has different excessive deficiencies: it can be partially filled with adhesive in the embossed groove range 12 6 in the state shown in Figure 1 7B (purple External hardening resin 1 2 0 ). At this time, it is not desirable in appearance, the adhesive; the extended state is judged to be defective. Thus, in the state shown in Fig. 1, 1C, in the embossed groove range In the case of 12 6 , only the adhesive (ultraviolet curing resin) 2 was found to be slightly overflowed. At this time, compared with the 17B, the adhesive (ultraviolet curing resin 120) overflowed.

大，外觀上並無障礙。因此’此時，黏著劑延伸狀態已判定爲良好° 如此’與第]7 B圖和第1 7 C圖相比參照時，不僅單純面積的大小’無法適正判定關於黏著劑延伸狀態。即， ϊ寸]K溢出^考劑的形狀良窳亦需加以判定。於此，本實施形態中’ p」將第]7 A圖至第]7 C圖的假想圓周軌跡，記憶於檢查用參數値記憶部5 0 5，於此圓周軌跡上，檢出急 (63) 1264714 速變化之畫像輸出訊號（白黑二値化訊號）之邊緣部份。然後，將此邊緣部份數，較設定於檢查用參數値記憶部505 的邊緣數5 5 3的値（臨界値）爲大的話，光碟1 2 2的檢查區域3 0 8之內周側透明範圍之黏著劑（紫外線硬化樹脂]2 0 ) ，判定爲形狀不良。Large, visually accessible. Therefore, at this time, the state in which the adhesive is extended has been judged to be good. Thus, when referring to the comparison between the seventh and fourth embodiments, the size of the simple area is not properly determined as to the state in which the adhesive is extended. That is, the shape of the ]]]K overflow tester needs to be judged. Here, in the present embodiment, 'p' is stored in the imaginary circular trajectory of the 7th to 7th C pictures in the inspection parameter 値memory unit 505, and the trajectory is detected on the circular trajectory (63). ) 1264714 The edge of the speed change image output signal (white black and white dimming signal). Then, if the number of edge portions is larger than the threshold (critical 値) set in the inspection parameter 値 the number of edges 5 5 3 of the memory unit 505, the inner peripheral side of the inspection area 3 0 8 of the optical disk 1 2 2 is transparent. The range of the adhesive (ultraviolet curing resin) 2 0 ) was judged to be in a bad shape.

將如此的判定處理顯示於第1 7 B圖及第1 7 C圖之各別情形。第1 7 B圖的狀態中，僅就圖示部份，即存在四個邊緣（邊緣以X顯示）。對此，第1 7C圖的狀態中，未存在如此的邊緣。於此，將如第1 7 B圖所示狀態，判定黏著劑延伸狀態「不良」，判定如第1 7 C圖所示時爲「良」。Such determination processing is displayed in the respective cases of the 1 7 B map and the 1 7 C map. In the state of Fig. 1 7 B, only the illustrated portion, that is, there are four edges (the edges are displayed by X). In this regard, in the state of Fig. 7C, such an edge does not exist. Here, in the state shown in Fig. 7B, it is judged that the adhesive extension state is "defective", and it is judged as "good" as shown in Fig. 7C.

接著，對於第1 3圖至第1 6圖所示「集合數」5 5 4，邊參照第1 8圖加以說明。第1 8圖係例示於光碟1 2 2的內周側透明範圍1 24，產生黏著劑形狀不良（氣泡）狀態之模式圖。如第1 8圖所示狀態中，於黏著劑（紫外線硬化樹脂 1 2 0 )中，發生氣泡6 0 1。氣泡6 0 1係於欲延展黏著劑（紫外線硬化樹脂 1 20)範圍中，可認識作爲局部欠缺黏著劑（紫外線硬化樹脂1 20)部份。如此的氣泡 60 1複數存在時，外觀上成爲不好形狀之故，黏著劑延伸狀態判定爲不良。於此，本實施形態中，參照白黑二値化畫像輸出訊號中的白畫像資料，使用畫像處理手法的「標記」，檢出如島狀之獨立白色範圍，由上依序附上號碼。如此，被標記之白色範圍爲氣泡6 0 ]。如第]8圖所示例示中，存在獨立某一局部範圍中之三個氣泡6 0]。然後，計數標記範圍的數，較該數値設定於檢查用參數値記憶部5 0 5之集合數 -67 - (64) 1264714 5 5 4値爲大的話，光碟1 2 2的檢查區域3 Ο 8之內周側透明範圍]2 4之黏著齊彳（紫外線硬化樹脂]2 0 )，則判定爲形狀不良。接著，對於如第]5圖，第]6圖所示「Α範圍」5 7 1 及「B範圍」5 7 2，參照第]9圖加以說明。第]9圖係例示於光碟]2 2的內周側透明範圍1 2 4，產生黏著齊lj (紫外線硬化樹脂〗2 0 )的形狀不良狀態之模式圖。如第]9圖所示，做爲光碟1 22的內周側透明範圍1 24之黏著劑（紫外線硬化樹脂]2 0 )的形狀不良，有延伸於光碟1 2 2的半徑方向，產生黏著劑（紫外線硬化樹脂1 2 0)的延伸不足之情形。如此，在外觀上爲不佳之故，黏著劑延伸狀態判定爲不良。但是，於如此的情形中，黏著劑（紫外線硬化樹脂 1 2 0)之延伸不足的面積並非很大，單就面積比較時，會有不判定該爲延伸不足的情形。因此，於本實施形態中，則較成爲光碟1 2 2之內周側之 A範圍5 7 1之判定臨限値，嚴格設定成爲外周側之B 範圍5 7 2之判定臨限値。更具體說明嚴格設定之事時，乃如圖1 5所例示之記憶保存於檢查用參數記憶部5 0 5之檢查用參數中，做爲透過範圍最大面積5 5 2之値，B範圍 5 7 2者則設定爲小。同樣地，記憶保存於如圖6所例示之檢查用參數記憶部5 0 5之檢查用參數中，非透過範圍最小面積5 6 ]之1値，設定爲B範圍5 7 2者較小者。由此，光碟 1 22之外周側之黏著劑（紫外線硬化樹脂1 20)之延伸不足乃較內周側，被嚴格坡加以判定。經由如此構成，例如如 - 68 - (65) 1264714 圖]9所例示，適切判定向光碟]2 2之半徑方向延伸之黏著劑（紫外線硬化樹脂丨2 〇)之延伸不足。Next, the "set number" 5 5 4 shown in Figs. 13 to 16 will be described with reference to Fig. 18. Fig. 18 is a view showing a pattern in which the shape of the adhesive is poor (bubble) in the inner peripheral side transparent range 1 24 of the optical disk 1 2 2 . In the state shown in Fig. 18, in the adhesive (ultraviolet curing resin 1 2 0 ), bubbles 610 are generated. The bubble 601 is in the range of the adhesive to be stretched (ultraviolet curing resin 1 20), and is recognized as a part of the partially underfilled adhesive (violet curing resin 1 20). When such a plurality of bubbles 60 1 are present in a plurality of cases, the shape is not good, and the state in which the adhesive is extended is judged to be defective. In the present embodiment, the white image data in the black-and-white image output signal is used, and the "mark" of the image processing method is used to detect the independent white range of the island shape, and the number is attached in order. Thus, the marked white range is the bubble 60]. As illustrated in Fig. 8, there are three bubbles 6 0] in a certain partial range. Then, the number of the mark range is counted, and the number of sets of the check parameter 値 memory unit 505 is set to -67 - (64) 1264714 5 5 4 値, and the inspection area 3 of the optical disk 1 2 2 is Ο In the inner peripheral side of the range of 8], the adhesiveness of 2 4 (ultraviolet hardening resin) 2 0 ) was judged to be a shape defect. Next, as shown in Fig. 5, the "Α range" 5 7 1 and the "B range" 5 7 2 shown in Fig. 6 will be described with reference to Fig. 9. Fig. 9 is a schematic view showing a state in which the shape of the adhesive is uniform in the inner peripheral side of the optical disk] 2 2 in the transparent range 1 2 4 , and the shape of the adhesive is lj (ultraviolet curing resin). As shown in Fig. 9, the adhesive (ultraviolet hardening resin) 20 of the inner peripheral side of the optical disk 1 22 has a poor shape, and extends in the radial direction of the optical disk 12 2 to produce an adhesive. (The ultraviolet curing resin 120 is insufficiently extended). Thus, the appearance of the adhesive is poor, and the state of the adhesive extension is judged to be poor. However, in such a case, the area where the adhesion of the adhesive (ultraviolet-curing resin 120) is insufficient is not large, and when the area is compared, there is a case where it is not determined that the elongation is insufficient. Therefore, in the present embodiment, the determination threshold A of the range B of the outer circumference side is set to be a strict threshold of the range A 5 517 of the inner circumference side of the optical disk 1 2 2 . When the strict setting is described in detail, the memory exemplified in FIG. 15 is stored in the inspection parameter of the inspection parameter storage unit 505, and the maximum area of the transmission range is 5 5 2, and the B range is 5 7 . 2 is set to small. Similarly, the memory is stored in the inspection parameter of the inspection parameter storage unit 505 as illustrated in Fig. 6, and the minimum area of the non-transmission range is 5 ], which is set to be smaller than the B range of 5 7 2 . As a result, the adhesion of the adhesive (ultraviolet curable resin 126) on the outer peripheral side of the optical disk 1 22 is less than that of the inner peripheral side, and is determined by strict slope. With such a configuration, for example, as shown in Fig. 9 - 68 - (65) 1264714, it is determined that the adhesion of the adhesive (ultraviolet curing resin 丨 2 〇) extending in the radial direction of the optical disk 2 2 is insufficient.

More specifically, it is possible to use an automatic machine or the like to remove the optical disc from the disc support table 2 0 ] 2 2, the judgment result corresponding to the Liangzhu project, the difference between the good product and the defective product, and the selection is made by transporting to a different specific place. form. The transport movement of the optical disc 1 2 2 using the disc support table 201 of such an automatic engine can be easily performed using the prior art. When it is determined that the extension is insufficient (Y in step S104) and when it is determined that the extension is excessive (Y in step S1 05), the data of the result of the peach inspection in the inspection result storage unit 506 is transmitted by the data (step S 1 06). As described above, according to the present embodiment, the illumination light from the ring illumination 301 can be uniformly reflected in the entire inspection region 3〇8 of the optical disk 1 22. Further, in the black-and-white image output signal, the adhesive portion is black, and the non-existing portion is white, and the signal of the adhesive (violet curing resin) 20) and the non-existing portion can be clearly separated. Therefore, the adhesive of the inspection region 308 (ultraviolet curing resin 1 2 0) can be excessively insufficient and can be inspected with high precision. Moreover, the working distance between the optical disc 22 and the CDD camera 2 0 3 can be sufficiently ensured. In this way, when the inspection is completed, the inner peripheral side transparent range 124 of the optical disc 122 formed by the disc substrates 103 and 104 to which the two boards are bonded can be obtained as the inspection area 308, and the inspection area is checked. Adhesive-stretched quality-fitted discs] 2 2. Further, after the execution of the above-mentioned sorting process, the result of the inspection can be obtained from the disc 1 2 2 of which the quality of the adhesive is not deteriorated. ^ 70 - (67) 1264714 The inventors of the present invention have actually implemented the present invention based on the above-described embodiments of the present invention to verify the effect. Here, two inspection mechanism portions 3 5 ] were constructed to carry out experiments. The details of the following are explained below. Figure 21 is a side view of the optical disc inspection apparatus used in the experiment. In the inspection mechanism portion 3 5 shown in Fig. 2, the imaging distance LD between the ring illumination 3 0 1 and the optical disc 1 2 2 needs to be 5 6 mm, which is a CDD camera using a general C chassis specification. Specific examples when measuring with the lens 2 0 3 a 〇 The area where the adhesion quality of the adhesive is examined is an inner diameter s 1 = 15 mm and an outer diameter S2 = 40 mm. The ring illumination 301 is also provided with a ring plate 3 0 3 of a diffuser plate having a thickness of 12 mm. First, in order to make the working distance longer, the front end of the CDD camera 2 0 3 and the front end of the ring illumination 301 are in the same position. At this time, the distance of the LD-156mm from the first principal point position HI of the lens 2 0 3 a to the disc 22 is H D = 1 8 8 mm. In this positional relationship, 6.8 < L1 < 27.4 L2 > 73.2 is calculated via S2 (1-LD/HD) < L1 < S1 (1 + LD / HD) L2 > S2 (1 + LD / HD).
