Field of the Invention The present invention relates to a lens transport container including a plurality of lens holding portions that can hold lenses of different sizes. [Prior Art] In order to carry an unprocessed lens or a processed lens onto a processing line, it is necessary to use a lens carrying container. In the lens transport container, a circular concave portion is formed on the upper surface of the disk-shaped container, and the lens to be transported is loaded into the concave portion from above to be transported. In order to prevent the lens incorporated in the circular recess from moving left and right during transportation, it is necessary to use a lens carrying container having a circular recess corresponding to the inner diameter of the outer diameter of the lens. Such a lens carrying container is disclosed in Patent Document 1. [Patent Document 1] Japanese Patent Laid-Open No. 25-6665 8 [Problem to be Solved by the Invention] Conventionally, a lens transport container having a circular recess corresponding to the size of a lens to be transported has been used. Therefore, when processing for lenses of different sizes, it is necessary to change the lens carrying container corresponding to the size. Therefore, it is necessary to prepare a lens carrying container corresponding to the size of the lens of the processing object in advance, as long as the lens is replaced. The container must also be replaced. In view of the above, an object of the present invention is to provide a lens transfer container which can hold a lens of a different size -4-200909314 while maintaining a displacement. [Means for Solving the Problem] In order to solve the above problems, a lens transport container according to the present invention includes: a container body; and a concave portion having a predetermined depth formed from an upper surface of the container body toward a bottom surface, or a through hole penetrating from the upper surface to the bottom surface; the recessed portion or the inner peripheral surface of the through hole is a stepped inner circumference having a plurality of step portions extending inward from the upper surface toward the bottom surface The upper end surface of each step portion and the inner peripheral end surface connected to the outer peripheral edge of the upper end surface define a lens for inserting and holding a lens corresponding to the contour of the inner peripheral end surface from above. Lens holding portion. In the lens carrying container of the present invention, a plurality of lens holding portions that can hold lenses having different sizes from above are formed. Therefore, by attaching the lens of the object to be transported to the lens holding portion corresponding to the size thereof, the lens can be transported without displacement. Therefore, it is not necessary to prepare a plurality of lens carrying containers for carrying lenses of various sizes, and it is not necessary to replace the lens carrying containers every time the lens of the object to be transported is replaced. Here, since the lens is generally circular, the upper end surface and the inner peripheral end surface of each step of the lens transport container may be an annular upper end surface and an annular inner peripheral end surface. Further, it is preferable that each of the lens holding portions is formed coaxially around the central axis of the container body. In this way, as long as the lens transport container is positioned, the lens held in the container is automatically positioned. Next, the width of the annular upper end surface of each step portion and the height ' of the annular inner peripheral end surface may be the same. Further, since the outer peripheral edge portion of the lens to be transported is generally at a right angle, the annular upper end surface of each step portion of the lens transport container and the annular inner peripheral surface may be combined with each other. It is straight. The width of the upper end surface of each step portion is preferably within a range of 〇.5 mm to 1 mm. The quotient of the inner peripheral end faces of the respective step portions is preferably in the range of 0.5 mm to 1 mm. In this manner, a plurality of lenses of various sizes can be transported by forming a plurality of lens holding portions having an increased inner diameter in a pitch of 0.5 mm to 1 mm. On the other hand, in order to simultaneously transport a plurality of lenses to each position, a plurality of the above-mentioned concave portions or a plurality of the above-mentioned through holes must be formed in the lens transport container, and each inner peripheral surface of each concave portion or each through hole must be formed. A plurality of the above lens holding portions. [Effect of the Invention] The lens transport container of the present invention includes a plurality of lens holding portions that can hold lenses of different sizes. Therefore, by carrying the container by a single lens, it is possible to carry lenses of different sizes without displacement. Therefore, not -6-200909314, it is necessary to prepare a plurality of lens carrying containers in order to carry lenses of different sizes, and it is not necessary to replace the lens carrying containers every time the lens of the object to be transported is replaced. [Embodiment] Hereinafter, an embodiment of a lens carrying container to which the present invention is applied will be described with reference to the drawings. Fig. 1 is a cross-sectional view showing a lens carrying container 1 to which the present invention is applied, and Fig. 2 is an enlarged sectional view showing the portion. The lens transport container 1 has a disk-shaped container body 2 having a predetermined thickness, and the container body 2 has a circular outer peripheral surface 2a. A through hole 5 is formed in the container body 2, and the through hole 5 is formed coaxially from the circular upper surface 3 toward the circular bottom surface 4, and coaxially with the central axis 1a of the container body 2. The inner peripheral surface of the through hole 5 is provided with a circular inner peripheral surface portion 6a which is tapered from a circular upper surface 3 to a circular bottom surface 4, and which is tapered to a conical shape; and a circular inner peripheral surface portion 6a from the lower end The bottom surface 4 has a circular inner peripheral surface portion 6 b having a certain inner diameter. The tapered circular inner peripheral surface portion 6a is apparent from Fig. 2, and is a stepped inner peripheral surface formed with a plurality of steps of a certain width and height. That is, the annular inner peripheral end surface 7(1)' which is connected to the circular upper surface 3 and which has the largest inner diameter is connected to the lower end edge, and forms an annular upper end surface 8(1) extending at a right angle to the inner side. A lens holding portion 9 (1) for holding and holding the circular lens 20 from above can be formed by the annular inner peripheral end surface 7 (1) and the annular upper end surface 8 (1). 200909314 A lens holding portion 9 (2) is formed on the lower side of the lens holding portion 9 (1). The lens holding portion 9 (2) is an annular inner peripheral end surface 7 (2) having a small diameter. And the annular upper end surface 8 (2). Similarly, the lens holding portions 9 (3), 9 (4), ..., which are gradually reduced in inner diameter from the lower end edge of the circular inner peripheral surface portion 6 are coaxially formed. . The annular inner peripheral end surface 7(n) of the lens holding portion 9(n) (n = 1, 2, 3....) is the same height and is set in a range of 0.5 mm to 1 mm. Similarly, each of the annular upper end faces 8 (n) has the same width and is set in a range of 0.5 mm to 1 mm. Therefore, each lens holding portion 9(n), that is, from the circular upper surface 3 toward the circular bottom surface 4, has a reduced inner diameter at a pitch of 0.5 mm to 1 mm. The lens 20 carried by the lens transport container 1 has a circular outline. An angle 2 1 on the side of the outer peripheral portion of the lens 20 is formed on the circular outer peripheral surface 22 so as to form a right angle perpendicular to the annular end surface 23. Therefore, the lens holding portion having the inner diameter corresponding to the outer diameter of the lens 20, for example, 'as shown in Fig. 2, the lens 20 is placed from above into the lens holding portion 9 (5), and the circular outer circumference of the lens 20 The surface 22 is just inserted into the inner side of the annular inner peripheral end surface 7 ( 5 ) of the lens holding portion 9 ( 5 ), and the annular end surface 23 of the lens 20 is placed on the lens holding portion 9 (5). The state of the annular upper end surface 8 (5). As described above, the lens carrying container 1 has a plurality of lens holding portions 9 (n) having different inner diameters. Therefore, when the lens 20 having a different outer diameter is transported, the lens 20 may be placed in the lens holding portion held in the inner diameter corresponding to the outer diameter of the lens 20 from above. Therefore, it is possible to carry the different mirrors by using a single lens to transport the container 1 without the displacement of -8 - 200909314. (Modification of Lens Transport Container) Each lens holding portion 9 (n) is defined by an annular inner peripheral end surface and an annular upper end surface 8 (n), but may be an elliptical inner circumference. The end face and the upper end face are specified. It suffices that the shape of the lens holding portion corresponds to the transparent shape of the object to be transported. Further, the annular inner circumferential end surface and the annular upper end surface 8 (n) of each lens holding portion 9 (n) are continuous in the circumferential direction, but are continuous surfaces. Even these faces can be convex or concave. What's more, the width D (8) and the height D (7) of these faces are different sizes. Of course, the upper end D (8) of each lens holding portion 9 (n) may also be different in size. Further, although the container body 2 has a through hole formed therein, a recessed portion having a depth may be formed instead of the through hole, and the inner peripheral surface of the recessed portion may be an inner peripheral surface. Here, a plurality of lens holding portions are formed. On the other hand, a perforation or a concave portion may be formed in the container main body 2, and a plurality of lens seals may be formed on the inner circumferential surfaces of the container body 2: Next, according to the third to fifth figures, the automatic conveyance applied to the mirror and the mirror may be applied. An embodiment of various devices for automatic processing illustrates the lens handling container 1. The outer diameter of the 7 (n), the shape of the shape, the shape of the rectangular mirror holding mirror 7 (n), can also be a non-curved surface, or the width of the surface can be a stepped shape of a plurality of temples . To perform the operation, -9-200909314 (honing device: transportation method using a belt conveyor) Fig. 3 is a honing device 30 for a lens. In this lens honing device 30, the lens carrying container 1 is placed on the belt conveyor 31 to be horizontally transported to the delivery position. Below the delivery position, a rotatable work disk 32 is provided, and the lens holder 33 is disposed above the processing disk 32 by means of an arm portion in a vertically movable manner. When the lens holder 33 is lowered onto the belt conveyor 31, the lens 2 in the lens carrying container 1 is pressed and sucked. Thereafter, while the belt conveyor 31 is retracted, the lens holder 33 is lowered toward the processing disk 32 side, and the lens 20 is pressed toward the processing disk 32 to perform honing processing. (Centering machine: handling method using the turntable) Fig. 4 is the centering machine 40 of the lens. In the centering machine 40, the lens transport container 1 is mounted on the turntable 41 for transport. Below the turntable 41, a lower lens holder 42 is provided. The lens 20 is carried toward the lower lens holder 42 by rotating and lowering the turntable 4 1 . Thereafter, by lowering the upper lens holder 43, the lens 20 is held and centered between the upper lens holder 43 and the lower lens holder 42, and the lens 20 is processed. After the processing, the upper lens holder 4 3 is raised, and thereafter, the turntable 41 is raised again. Then, the turntable 41 is rotated before the next lens transfer container 1 reaches the position on the operation axis of the upper lens holder 43 and the lower lens holder 42. (Mulching device: conveying method using a rotating arm) -10-200909314 Fig. 5 is a honing device 50 for a lens. In the honing device 50, a rotating arm 5 1 ' is provided instead of the belt conveyor 3 1, and the lens carrying container 1 is attached to the front end of the rotating arm 51, and the portion is conveyed toward the lower side of the lens holder 52. The portion is different from the honing device of Fig. 3, but the other portions are the same as the honing device 30 of Fig. 3.
