In this embodiment, up to 24 lenses 2 are each held substantially vertically. , shows a case where the lens rack 1 is applied to a lens rack 1 that stores lenses in two rows with 12 lenses in each row.

[0009] The lens rack 1 includes two types of frame members 3A and 3B having different lengths and shapes. , 4A, and 4B are joined into a rectangular frame shape. Frame member 3A , 3B, 4A, 4B materials are not particularly limited, but may have heat resistance, chemical resistance, etc. It is desirable to use a superior material, such as stainless steel. rack body 5 Each corner has a step to improve space efficiency during storage, etc. The stacking portions 6 are integrally provided and protrude upward, respectively. Each stacking section 6 is It is formed by extending the ends of the frame members 3A, 3B, 4A, and 4B upward. Therefore, it is composed of two side plate parts 6a and 6b that are L-shaped in plan view and orthogonal to each other. Moreover, a square bar body 7 is fixed to the inside thereof by brazing or the like. Square rod 7 The upper surface is approximately flush with the upper surface of the stacked part 6, and has an engaging protrusion 8 at the center of the upper surface, and an engagement protrusion 8 at the center of the lower surface. An engagement recess 9 slightly larger than the engagement protrusion 8 is formed. multiple lenses When stacking lens racks 1, make sure to engage the engaging protrusions 8 of the upper and lower lens racks 1. By fitting the matching recesses 9 into each other, the position of the lens rack 1 in the front-back and left-right directions can be adjusted. This enables stable loading of the lens rack 1 and prevents misalignment. This prevents it from falling or collapsing.

0010 Among the frame members constituting the rack body 5, a pair of frame members 3A, 3 having a short length A support rod 10 is horizontally suspended between B. This support rod 10 has a length of frame members 3A and 3B. It is inserted and fixed into the insertion hole provided in the center in the hand direction, and each row of lenses is attached to the bottom side. Twelve supporting members 14 that commonly support the lower surface of the supporting rod 10 are arranged at regular intervals. are arranged in parallel in the longitudinal direction. The support member 14 is made of stainless steel or the like. It consists of a straight line spring, with an annular part 16 in the center in the longitudinal direction, and a ring part 16 in each row at both ends. The support parts 17A and 17B that support the lower surface of the lens are bent and formed together. installed on the body. This support member 14 is approximately horizontal with respect to the support rod 10. The annular portion 16 is fixed to the lower surface of the support rod 10 with a set screw 15 so that the annular portion 16 is orthogonal to the support rod 10. As a result, it can be elastically deformed in the vertical direction. of lens 2 in each row The support parts 17A and 17B that support the lower surface are bent into a Y-shape when viewed from the side, as shown in FIG. By forming a V-shaped groove 19 in the support portion that supports the lower surface of the lens. ing. Note that the support rod 10 and the support member 14 do not need to be strictly orthogonal; It may be slightly inclined as long as it does not interfere with the support of the lower surface.

[0011] Also, a space between the pair of frame members 3A and 3B is commonly used for each row of lenses 2. A holding member 20 is suspended horizontally. This holding member 20 is made of fluororesin or the like. By forming a rod-shaped body in the shape of an abacus bead, there are 12 lenses forming a V-shape on the circumference. It has a ring holding groove 22. The lens holding groove 22 corresponds to the arrangement pitch of the support member 14. It is formed at the same pitch as the chi. In this case, the lens holding groove 22 is V-shaped. It is not limited to the shape, but may be of various shapes such as a rectangle or a U-shape.

0012 Furthermore, a pair of left and right rod-shaped bodies 24, 25 are provided between the pair of frame members 3A, 3B. It is horizontally suspended on both sides of the support rod 10 so as to be parallel to the support rod 10. These rod-shaped bodies 24 , 25 have a circular cross-sectional shape at both ends and a square cross-sectional shape at the center. and both ends thereof are elongated holes 26 formed in the pair of frame members 3A and 3B in the left-right direction. , 27 in a slidable manner, and screwed onto the protruding ends of the nuts 28. Therefore, it is fastened and fixed. In addition, in the center of each rod-shaped body 24, 25, there is a register in each row. A clamping member 30 elastically clamps the side surface of the lenses 2 together with the clamping member 20. is installed.

[0013] The holding member 30 is formed by punching an elastic metal plate such as stainless steel into a comb shape. By forming the fixed base 30A, the lower end is connected to the fixed base 30A. Six elastic support legs 30B are bent in a V-shape so that the central part is convex outward; It has a substantially horizontal mounting portion 30C provided at the upper end of the elastic support leg 30B, and The upper surface of each mounting portion 30C is attached to the side surface of the lens by the elastic force of the elastic support leg 30B. The lens 2 is clamped from both sides together with the lens holding groove 22 of the clamping member 20. A holding plate 32 is fixed with screws. The holding plate 32 is made of fluororesin or the like. a flat surface that holds the lens side surface on the inner surface facing the holding member 20; A V-shaped lens receiving groove 33 is formed. And configured like this Two clamping members 30 are arranged in parallel for each of the rod-shaped bodies 24 and 25, and It is fixed with screws 35.

[0014] The distance between the lens holding groove 22 and the lens receiving groove 33 is the smallest distance that should be stored and cleaned. The diameter of the lens 2 is set to be smaller than the diameter of the lens 2. To set this interval, loosen the nut 28, The rod-like bodies 24 and 25 can be moved and adjusted along the long holes 26 and 27, and rotated around the central axis. This can be easily done by doing this. Also, the support rods 24 and 25 are When the elastic support leg 30B is rotated in a different direction, the elastic force of the elastic support leg 30B when holding the lens 2 is changed. be able to.

[0015] In the lens rack 1 having such a configuration, the lens 2 is stored in the rack 1. When storing, open the elastic support legs 30B of the outer clamping member 30 toward the outside and remove the clamping member. Set the distance between the holding members 20 and 30 to be larger than the lens diameter, and while maintaining this state, Insert the lens 2 from above almost vertically between Place it on 7A (or 17B). At this time, the horizontal maximum diameter of lens 2 is The lens 2 is mounted on the support part 17A so that it is slightly lower than the lens holding groove 22 and the lens receiving groove 33. (or 17B) to elastically deform the support member 14 downward. child After placing the lens 2 on the support part 17A (17B) of the support member 14 as shown in FIG. , when the elastic support leg 30B is released and elastically returned, the spring force of the elastic support leg 30B The lens receiving groove 33 of the holding plate 32 is pressed against the side surface of the lens 2, and the lens holding groove 33 is pressed against the side surface of the lens 2. The side surface of the lens is held together with 22. Therefore, the lens 2 has a lower surface and both left and right sides. It is held stably at three points on the side and stored in the lens rack 1, and then the rack 1 It is also immersed in a cleaning solution for a certain period of time, and is cleaned by an ultrasonic generator.

[0016] According to the lens rack 1 having such a configuration, the lower surface of the lens is supported. The lens 2 is elastically supported by the holding member 14, and one side of the lens 2 is elastically supported by the holding member 30. Since it is supported, lenses 2 of various sizes with different lens diameters can be stored at the same time. In addition, since the support member 14 is formed of a wire spring, the cleaning liquid It is sharp and does not collect on the bottom surface of the lens, staining the lens 2, or when used for multi-tank cleaning. There is no risk of it getting mixed into the cleaning tank.

[0017] Note that the above embodiment is applied to a lens rack that stores lenses 2 in two rows. However, the present invention is not limited to this, and even if there is only one row, , may be two or more columns. In addition, the holding member 30 is formed separately, and each rod-shaped body 24, 25 is provided, but it goes without saying that it may be configured with only one.

[0018]

[Effect of the idea]

As explained above, according to the lens rack according to the present invention, lenses can be held at three points. The lens can be held stably and reliably, and there is also a support that supports the bottom surface of the lens. Since the holding member is made of a wire spring, the cleaning liquid drains very easily. The side surface of the upper lens is elastically held by the holding member, so lenses with different diameters can be Can hold and store lenses of various sizes at the same time. Therefore, for lenses The number of rack types can be reduced, and rack management is easy. Also, one One clamping member is composed of a rod-shaped body with a plurality of lens holding grooves on the circumferential surface, and the other clamping member is If the holding member is composed of a leaf spring that can be elastically deformed in the holding direction, it is easy to attach and detach the lens. Its practical effects are very large, such as being easy to use.
