Description

  The present invention relates to a technique for supporting optical elements such as lenses and mirrors, wafers such as silicon wafers, liquid crystal cells, glass substrates of liquid crystal cells, and the like.

  In general, an optical element such as a lens that has been subjected to surface processing or the like is supported on a support tray for conveyance or the like. A plurality of support portions that support the optical element are formed on the support tray. As a support portion, a structure that can cope with optical elements having different outer diameters has been proposed (Patent Document 1).

  This support portion has a structure in which three or four support protrusions are projected upward from a flat base surface. The support protrusions are arranged on the same circumference with a predetermined interval so as to surround the disk-shaped optical element. Each support protrusion has a contact surface that contacts the outer edge of the optical element as an inclined surface. The optical element can be placed on and removed from the support portion by an operator inserting a finger into the gap between adjacent support protrusions and picking the optical element.

  The contact surface formed on each support protrusion is an inclined surface that faces the center side of the optical element as it goes from the upper end to the lower end side. For this reason, the optical element is supported below the support protrusion as the outer diameter decreases, and is supported above the support protrusion as the outer diameter increases.

  On the other hand, apart from a support tray (hereinafter referred to as a storage tray) that supports an optical element on each support portion, another support tray having the same structure is used as a lid. A support tray used as a lid (hereinafter referred to as a lid tray) is placed upside down on a storage tray that supports the optical element. At that time, the contact surface of the support protrusion protruding downward from the lid tray comes into contact with the outer peripheral edge of the optical element supported by each support portion, and the optical element is fixed so as to be sandwiched between the upper and lower support protrusions.

  The support tray that forms the storage tray and the lid tray has support portions symmetrically formed with respect to the center position in the width direction of the support tray. The support protrusions of the support portion at the symmetrical position are formed around the center point of the support portion with an angle of 90 degrees. For this reason, the support protrusion of the lid tray is fitted into the space between the support protrusions of the storage tray.

  In such a conventional support tray, when the optical elements stored in the storage tray are transported, the storage trays are generally stacked in multiple stages, for example, five stages. In this case, since the storage tray and the lid tray are set as one set, a support tray that is double the number of stages is required, resulting in an increase in cost.

  Further, when the support portions are arranged in a plurality of rows on the support tray, the support protrusions of the support portion cannot all be arranged in the same direction in order to be usable as a lid tray. Therefore, in some support parts, even if the position of the gap formed between adjacent support protrusions is optimal for putting a finger and picking it, picking an optical element for another support part. It is not optimal for.

JP 10-059453 A

  An object of the present invention is to provide a support tray that can support plate-like bodies such as optical elements having different outer diameters and does not require a separate lid tray.

  Another object of the present invention is to provide a support tray capable of optimally picking a plate-like body in addition to the above-described object.

  A first configuration of a support tray that solves the problem includes a substrate portion having a flat substrate body, and one or a plurality of storage portions formed on the substrate body that stores a plate-shaped object. . The storage portion includes a support pocket portion formed on the front surface side of the substrate body that supports the object to be stored, and a pressing portion formed on the back surface side of the substrate body corresponding to the support pocket portion. . A plurality of the support pocket portions are arranged at intervals so as to surround a storage region in which the object to be stored is stored, and a front portion that enters the storage region becomes higher from the inside to the outside of the storage region. An inclined surface that is inclined upward is provided, and the inside of the substrate main body side having an open bottom has a support that forms a protruding portion that protrudes upward from the cavity. The presser portion is arranged corresponding to the space between the adjacent supports, and the front portion entering the presser region corresponding to the storage region in the front and back direction becomes higher from the inner side to the outer side of the presser region. The presser body has a pressing body that has an inclined surface that is inclined downward, and the inside of which the upper surface on the substrate body side is open projects out downward of the cavity.

  A second configuration of the support tray that solves the problem is that, in the first configuration of the first support tray described above, a plurality of the storage units are arranged in two orthogonal axes, and the presser body is orthogonally crossed. It is arranged in the axial direction or one of the axial directions.

  According to a third configuration of the support tray for solving the problem, in the support tray having any one of the configurations described above, the inclined surface of the front portion of the support body and the presser body is on the rear surface side relative to the inclination rate of the front side portion. The slope of the part is increased.

  A fourth configuration of the support tray that solves the problem is that, in the support tray having any one of the configurations described above, a plurality of the storage portions are arranged in the substrate body, and the support bodies or pressers facing each other in the adjacent storage portions are opposed to each other. Are formed so as to be integrally connected to each other, and the inside opening of the substrate body has a hollow continuous portion.

  According to a fifth configuration of the support tray for solving the problem, in the support tray having any one of the configurations described above, the protrusion protruding from the substrate body and the cavity inside the protrusion overlap the support tray vertically. And the protrusion fits into the cavity.

  According to the present invention, the support pocket portion can support a lens having an arbitrary diameter within a predetermined diameter range, for example. When the support trays are stacked in a plurality of stages, the pressing portion of the upper support tray presses the edge of the lens supported by the lower support pocket portion from above. For this reason, the number of support trays may be a support tray with the number of stacked layers and a single support tray used as a lid that covers the uppermost support tray, and the number of support trays used can be greatly reduced compared to the conventional case.

  According to the second aspect of the present invention, the support tray is placed on a workbench or the like in accordance with one of the two orthogonal axes, and the object to be stored is picked up with a finger or stored or removed. Since the finger enters the upper surface opening of the presser body with a natural posture of picking an object with the finger, it is possible to efficiently store and remove the object to be stored.

  According to the third aspect of the present invention, even a lens having a large outer diameter and a small thickness or a lens having a small outer diameter and a large thickness can be stored in the same storage portion, and the same number of lenses can be placed on the support tray. Can be stored. In addition, since the height of the support pocket portion and the presser portion can be set to the same height, for example, when forming by a vacuum forming method, it is possible to prevent the thickness of the support pocket portion and the presser portion from being reduced.

  According to the fourth aspect of the invention, the rigidity of the substrate portion can be increased, the object to be stored such as a lens to be stored can be stably supported, and rattling of the object to be stored during transportation can be prevented. it can.

  The support tray 1 of the present embodiment stores a plurality of optical elements L such as disk-shaped lenses, which are storage objects, in a horizontal posture. In the support tray 1, storage units 5 that store the optical elements L in the substrate unit 3 are arranged in a matrix of m (m ≧ 1) rows × n (n ≧ 1) columns. In the present embodiment, the storage units 5 are arranged in 4 rows × 5 columns. The support tray 1 is formed by a vacuum forming method using, for example, polyethylene terephthalate resin (PET) or the like. If the three axes orthogonal to each other are the X axis, Y axis, and Z axis, the row direction is the Y axis direction and the column direction is the X axis direction in the figure.

  The storage portion 5 has a support pocket portion 7 at the upper side and a presser portion 9 at the lower side with the substrate body 31 forming the upper surface of the substrate portion 3 as a boundary. The substrate part 3 includes a side wall 32 having a height H1 extending downward from the four sides of the substrate body 31 formed in a rectangular plane and extending horizontally downward from the lower end of each side wall 32. 33. The side wall 32 is formed in a tapered shape that tapers slightly toward the top.

  The support pocket portion 7 has four support bodies 71, 72, 73, 74 projecting upward along the Z-axis direction around the center point O in the circumferential direction. The first support body 71, the second support body 72, the third support body 73, and the fourth support body 74 are equally spaced (equal angle) in the circumferential direction so as to surround the storage area (see FIG. 3) of the optical element L. Placed in.

  The first support body 71 and the third support body 73 that are opposed to each other along the X-axis direction are arranged symmetrically with respect to the center point O, and the second support body 72 that is arranged to face each other along the Y-axis direction. The fourth support 74 is arranged point-symmetrically about the center point O. The 1st support body 71-the 4th support body 74 are formed in height H2. In the present embodiment, the height H <b> 2 of the first support body 71 to the fourth support body 74 is substantially the same as the height H <b> 1 of the side wall 32 of the substrate unit 3.

  The first support body 71 to the fourth support body 74 have a bottom surface opening 75 opened to the substrate body 31 and have a hollow shape in which a support body cavity C1 is formed. The support body cavity C1 of the first support body 71 to the fourth support body 74 is formed in a shape similar to the outer diameter shape of the first support body 71 to the fourth support body 74. Each of the hollow support bodies 71 to 74 is formed in a substantially fan shape in a top view that expands from the center point O toward the radially outer side with a center angle α.

  In the first support body 71 to the fourth support body 74, the side close to the center point O is the upper front part 76 and the far side is the back part. The upper front portion 76 is formed on a linear inclined surface (inclination angle: γ) facing upward in the Z-axis direction. The inclination direction of the upper front portion 76 forming the inclined surface is such that the radial outer end side (outer end) 77 is higher and the center point O side (inner end) 78 is lower. Therefore, the 1st support body 71-the 4th support body 74 are formed in the mountain shape of the convex shape toward the upper side of the substantially right triangle shape. In addition, the top surface 76a of each upper front part 76 of the 1st support body 71-the 4th support body 74 is formed in the substantially horizontal flat surface.

  The first support body 71 to the fourth support body 74 are formed in a tapered shape that tapers slightly toward the front end side from the substrate body 31 side. Therefore, when the support trays 1 are stacked, the first support body 71 to the fourth support body 74 of the lower support tray 1 become the support body cavities of the first support body 71 to the fourth support body 74 of the upper support tray 1. Plugged into C1. At that time, the side wall 32 of the substrate unit 3 in the lower support tray 1 is fitted inside the side wall 32 of the substrate unit 3 in the upper support tray 1. In the present embodiment, the inner diameter dimension of the support cavity C1 is narrower by the plate thickness than the outer diameter dimensions of the first support body 71 to the fourth support body 74, so that there is a gap corresponding to the difference in the plate thickness. Inserted.

  The substrate body 31 of the substrate unit 3 is provided with an upper space S1 between adjacent supports (71 to 74). The upper space S1 has substantially the same size as the planar shape of the support (71 to 74).

  The outer end 77 and the inner end 78 of each support 71 to 74 are set on the same circumference with the center point O as the center. The upper front surface portion 76 that forms the inclined surface of each of the supports 71 to 74 has a cross section perpendicular to the inclined surface curved in a concave shape (arc shape) so that it can stably come into contact with the outer periphery of the supporting optical element L. Yes.

  The distance (large diameter) between the outer end 77 of the first support 71 (second support 72) and the outer end 77 of the third support 73 (fourth support 74) is D1, and the first support 71 (first The distance (small diameter) between the inner end 78 of the second support 72) and the outer end 77 of the third support 73 (fourth support 74) is D2 (D1> D2).

  Here, an inverted frustoconical object having an inclination angle of γ, an outer diameter of the small-diameter bottom surface is D2, and an outer diameter of the large-diameter upper base is D1 is set to the center point O of the support pocket portion 7 and the center of the object to be stored When the points are put together and placed on the supports 71 to 74, the outer peripheral surface of the object to be stored comes into contact with the entire upper front surface portion 76 of the supports 71 to 74.

  Therefore, optical elements L having different outer diameters within the outer diameter range of D1 to D2 can be placed in the storage area in the support pocket portion 7. The optical element L placed in the support pocket portion 7 comes into contact with the upper front surface portion 76 existing in the storage area of the first support body 71 to the fourth support body 74 and is supported in a horizontal posture.

  Next, the presser part 9 of the storage part 5 will be described.

  The presser 9 corresponds to the upper space S1 between the first support 71 and the second support 72, and the upper space between the first presser 91 and the second support 72 and the third support 73. The third presser body 93, the fourth support body 74 and the first support body 71 corresponding to the upper space S1 between the second presser body 92 and the third support body 73 and the fourth support body 74 corresponding to S1. The fourth presser bodies 94 are respectively arranged corresponding to the upper space S1 between them.

  As shown in FIG. 5, the first presser body 91 to the fourth presser body 94 are formed below (on the back surface side) of the substrate body 31, and are equally spaced (equal angles) in the circumferential direction around the center point O. It is arranged. Therefore, if the first support body 71 is disposed at a position of 0 degree angle (on the X axis), the first presser body 91 to the fourth presser body 94 are 45 degrees and 135 in order in the clockwise direction. It is arranged at angular positions of 225 degrees, 225 degrees, and 315 degrees.

  The first presser body 91 to the fourth presser body 94 protrude downward along the Z-axis direction. The first presser body 91 and the third presser body 93, and the second presser body 92 and the fourth presser body 94, which are arranged to face each other, are arranged symmetrically with respect to the center point O and are formed at a height H3. In the present embodiment, the height H <b> 3 of the first presser body 91 to the fourth presser body 94 is substantially the same as the height H <b> 1 of the side wall 32 of the substrate unit 3.

  That is, when the support tray 1 is placed on a work table or the like, the support tray 1 bends because the presser bodies (91 to 94) of the presser units 9 abut on the work table in addition to the flange portion 33. It is mounted on a workbench without. For this reason, it is possible to prevent the substrate body 31 from fluttering when the optical element L is placed or picked up in the support pocket portion 7 with the support tray 1 placed on the work table.

  The first presser body 91 to the fourth presser body 94 have an upper surface opening 95 that is open to the substrate body 31 and have a hollow shape in which a presser body cavity C2 is formed. Each of the hollow pressers 91 to 94 is formed in a substantially fan shape in a bottom view extending from the center point O toward the radially outer side with a center angle β, and the lower front surface portion 96 faces the center point O side. Are formed on an inclined surface (inclination angle: γ).

  In the present embodiment, the height below the substrate body 31 in the Z-axis direction is “low” when it is closer to the substrate body 31 and “high” when it is far away. In the inclination direction of the lower front surface portion 96 that forms an inclined surface facing downward with respect to the Z-axis direction in the first presser body 91 to the fourth presser body 94, the radially outer end side (outer end) 97 is high, The center point O side (inner end) 98 has a low slope. Therefore, the 1st presser body 91-the 4th presser body 94 are formed in the convex-shaped mountain shape toward the downward direction of the substantially right triangle shape. Further, the lower front surface portion 96 is curved in an arc like the upper front surface portion 76 of the first support body 71 to the fourth support body 74. In addition, the lower top surface 96a of each lower front surface part 96 of the 1st presser body 91-the 4th presser body 94 is formed in the substantially horizontal flat surface.

  The inner ends 98 of the first presser body 91 to the fourth presser body 94 and the inner ends 78 of the first support body 71 to the fourth support body 74 substantially coincide on the same circumference with the center point O as the center. The outer ends 97 of the first presser body 91 to the fourth presser body 94 and the outer ends 77 of the first support body 71 to the fourth support body 74 are on the same circumference centered on the center point O. They are formed approximately in agreement.

  The first presser body 91 to the fourth presser body 94 project downward from the substrate body 31 side along the Z-axis direction, and are formed in a tapered shape that tapers slightly toward the projecting tip side. Between the first presser body 91 and the second presser body 92, a lower space S2 in which the bottom opening 75 of the second support body 72 faces is formed. Similarly, between the second presser body 92 and the third presser body 93, between the third presser body 93 and the fourth presser body 94, and between the fourth presser body 94 and the first presser body 91, A lower space S2 is formed in which the bottom openings 75 of the third support body 73, the fourth support body 74, and the first support body 71 face each other. The lower space S2 is formed in substantially the same size as the planar shape of the presser bodies (91 to 94).

  For this reason, when the support trays 1 are stacked, the storage portions 5 corresponding to the upper and lower support trays 1 and 2 are arranged so that the first presser body 91 to the fourth presser body 94 of the upper support tray 1 are the same. It is located corresponding to each upper space S1 of the lower support tray 1. Further, the first support body 71 to the fourth support body 74 of the lower support tray 1 are positioned corresponding to the lower spaces S <b> 2 of the upper support tray 1.

  When the upper support tray 1 is pushed down toward the lower support tray 1, the pressers (91 to 94) of the upper tray 1 are inserted into the upper surface opening 95 of the lower support tray 1, and the presser cavity C2 It is inserted in.

  In this embodiment, since the inner diameter dimension of the presser body cavity C2 is narrower by the plate thickness than the outer diameter dimensions of the first presser body 91 to the fourth presser body 94, there is a gap corresponding to the difference in the plate thickness. Fitted. At that time, the first presser body 91 to the fourth presser body 94 and the first support body 71 to the fourth support body 74 are alternately positioned in the circumferential direction.

  The diameters of the outer ends 97 of the first presser body 91 to the fourth presser body 94 centered on the center point O are the diameters of the outer ends 77 of the first support body 71 to the fourth support body 74 centered on the center point O. The diameter is approximately the same as D1 (D1). The diameters of the inner ends 98 of the first presser body 91 to the fourth presser body 94 centered on the center point O are the inner ends 78 of the first support body 71 to the fourth support body 74 centered on the center point O. The diameter is substantially the same (D2) as the diameter D2.

  Here, the center point O of the holding portion 9 is set to the object to be stored with respect to the truncated conical object having the inclination angle γ, the outer diameter of the upper surface of the small diameter D2 and the outer diameter of the lower surface of the large diameter D1. When the pressers 91 to 94 are covered in accordance with the center point, the entire lower front surface portion 96 of each presser 91 to 94 comes into contact with the outer peripheral surface of the storage body.

  When the outer diameter of the optical element L is small within the range of D1 to D2, if the outer diameter of the optical element L is small, the lower front surface portion 96 of each presser body 91 to 94 is located outside the optical element L at a position close to the inner end 98. The distance between the optical element L and the substrate body 31 in the Z-axis direction is shortened in contact with the peripheral edge. On the other hand, when the outer diameter of the optical element L is large, the lower front surface portion 96 of each presser 91 to 94 comes into contact with the outer peripheral edge of the optical element L at a position close to the outer end 97, and the optical element L and the substrate body The distance in the Z-axis direction with 31 is increased.

  As shown in FIGS. 1 and 2, the support tray 1 is formed with a total of 20 storage portions 5 of 4 rows × 5 columns. When the support bodies (71 to 74) exist between the support pocket sections 7 of each storage section 5 and the adjacent support pocket sections 7, the support bodies (71 to 74) facing each other are connected. The connecting portion 79 is connected and integrated. The continuous portion 79 is a convex shape that protrudes upward from the substrate body 31 in the Z-axis direction, and the inside is formed in a hollow shape. The inside of the continuous portion 79 has a continuous cavity C3 that communicates with the support body cavity C1 of the support bodies (71 to 74). Similar to the support bodies (71 to 74) and the support body cavity C1, the outer shape of the connection part 79 and the connection cavity C3 are arranged so that the connection part 79 is placed in the continuous cavity C3 when the support tray 1 is stacked vertically. It is inserted in.

  As described above, the support bodies (71 to 74) facing each other in the adjacent support pocket portions 7 are connected and integrated by the connecting portion 79, whereby the bending rigidity and the torsional rigidity of the support tray 1 are increased.

  When placing the optical elements L on the support tray 1 according to the present embodiment described above, the operator picks the optical elements L one by one with his / her fingers, and the first support body 71 to the fourth support body of the support pocket portion 7. 74. At that time, a fingertip that picks up the optical element L enters the upper surface opening 95 opened in the substrate body 31 located between the first support body 71 to the fourth support body 74. For this reason, the optical element L can be easily placed in the support pocket portion 7.

  In the present embodiment, the support tray 1 has the first support 71 and the third support 73 of the support pocket portion 7 arranged along the X-axis direction, and the second support 74 and the fourth support 74 are arranged. Although it is arranged along the Y-axis direction, it may be arranged by shifting the angle of 45 degrees in the circumferential direction (for example, clockwise direction) around the center point O. In this case, the fourth presser body 94 and the second presser body 92 are arranged along the X-axis direction, and the first presser body 91 and the third presser body 93 are arranged along the Y-axis direction. In this case, the upper surface opening 95 is located on the X axis and the Y axis. Adjacent pressers (91 to 94) are connected to each other by the connecting portion.

  As a method of using the support tray 1, two support trays 1 are arranged side by side on a workbench, for example, an operator picks and picks up the optical element L placed on the support tray 1 arranged on the left side and visually checks it. There is a case in which an inspection is performed and placed on the support tray 1 arranged on the right side as it is. In this case, when the upper surface openings 95 are arranged on the X axis and the Y axis, the operation of transferring from the left support tray 1 to the right support tray 1 can be easily performed.

  That is, when the optical element L is picked up with a finger of the hand, the optical element L is picked up with the thumb and index finger or middle finger of the hand. Then, the optical element L picked up with the thumb and the index finger inserted in the spaced apart upper surface opening 95 on the X axis is transferred to the support pocket portion 7 of the right support tray 1. At that time, while maintaining the posture in which the optical element L is picked, the support pocket portion 7 on which the thumb and index finger picking the optical element L are transferred simply by swinging the arm to the right side with the elbow of the operator as a fulcrum. The inspected optical element is inserted into the upper surface opening 95 and can be placed on the first support body 71 to the fourth support body 74 of the support pocket portion 7 reliably and easily.

  Next, a case where a plurality of support trays 1 are stacked, conveyed, and stored will be described. As shown in FIG. 6A, optical elements L are respectively placed in the 20 support pocket portions 7 of the lower support tray 1 indicated by a solid line. For example, when the support trays 1 are stacked in five stages, five support trays 1 on which the optical elements L are placed and empty support trays 1 indicated by broken lines on which the optical elements L are not placed are used for the lid. Prepare one as

  The support trays 1 on which the optical elements L are placed are stacked one above the other. On the lower support tray 1, the optical element L is supported by the support pocket portion 7 in contact with the upper front surface portion 76 of the first support body 71 to the fourth support body 74. When the upper support tray 1 is positioned above the lower support tray 1 in the front / rear direction and the left / right direction, the holding portion 9 provided on the back side of the upper support tray 1 becomes the support pocket portion of the lower support tray 1. 7 is located above.

  The pressers 91 to 94 of the presser 9 of the upper support tray 1 are positioned above the upper surface openings 95 of the lower support tray 1. These upper surface openings 95 arranged in the lower support tray 1 communicate with the presser body cavities C2 of the presser bodies 91 to 94 of the lower support tray 1.

  On the other hand, the 1st support body 71-the 4th support body 74 of the lower support tray 1, and the connection part 79 are below each bottom face opening 75 opened to the back surface side of the upper support tray 1, and the connection cavity C3. To position. Each bottom opening 75 of the upper support tray 1 communicates with the support cavity C <b> 1 of the first support 71 to the fourth support 74 of the upper support tray 1.

  Subsequently, as shown in FIG. 6B, when the upper support tray 1 is lowered toward the lower support tray 1, the first presser 91 to the fourth presser of each presser portion 9 of the upper support tray 1. The lower front surface portion 96 of the body 94 comes into contact with the outer peripheral edge of the optical element L supported by the support pocket portion 7 of the lower support tray 1. Here, the lowering of the upper support tray 1 ends. At that time, the first presser body 91 to the fourth presser body 94 of each presser portion 9 of the upper support tray 1 are fitted into the presser body cavities C <b> 2 of the lower support tray 1. Similarly, the first support body 71 to the fourth support body 74 and the continuous portion 79 of the lower support tray 1 are fitted into the support body cavity C1 and the continuous space C3 of the upper support tray 1. For this reason, the upper support tray 1 can be pushed down with respect to the lower support tray 1 to the position where the optical element L is pressed by the first presser body 91 to the fourth presser body 94 of each presser portion 9. The optical element L supported by the support pocket portion 7 is pressed from above by the pressing portion 9 of the upper support tray 1 and is stored in the storage portion 3 of the upper and lower support trays 1 without rattling up and down and left and right. In addition, in FIG.6 (b), illustration of the 4th support body 74 of the lower support tray 1 is abbreviate | omitted.

  In particular, since the optical element L having a small outer diameter is placed on the support body (71 to 74) at a position close to the substrate body 31, the distance between the upper support tray 1 and the lower support tray 1 is reduced. However, the support bodies (71 to 74) and the presser bodies (91 to 94) are fitted in the opposing support body cavities C1 and presser body cavities C2, respectively, so that the upper and lower support trays 1 can approach each other. . For this reason, the range of the diameter of the optical element L that can be accommodated can be widened.

  When the support trays 1 on which the optical elements L are placed are stacked in five stages, an empty support tray 1 is placed on the uppermost support tray 1 and functions as a lid. Then, the entire loaded stack is bound by a binding band or the like. When the holding bodies (91 to 94) are provided on the X-axis and the Y-axis on the substrate body 31, the substrate body 31 has a space S2 in a straight line along the X-axis direction and the Y-axis direction on the upper surface of the substrate body 31. It is formed over both ends. Therefore, if the binding band is hung on the space S2 of the support tray 1 used as a lid, the binding band can be hung without any deviation.

Second Embodiment FIG. 7 shows a second embodiment of the support tray according to the present invention.

  FIG. 7 shows a schematic longitudinal sectional view of the support tray. In FIG. 7, the same members as those shown in FIGS. 1 to 6 are denoted by the same reference numerals, and the description thereof is omitted. Further, the support tray 1 in the second embodiment forms storage portions 5 in m rows × n rows as in the first embodiment. Even if it is the structure which has arrange | positioned the support body (71-74) on the X-axis and the Y-axis, the structure which has arrange | positioned the presser body (91-94) may be sufficient.

  In the first embodiment described above, the upper front surface portion 76 of the support body (71 to 74) and the lower front surface portion 96 of the presser body (91 to 94) in the storage portion 5 are linear inclined surfaces. Further, the upper end of the optical element L placed on the support (71 to 74) extends to the upper end of the support (71 to 74). For this reason, as shown in FIG. 7, when the thickness of the optical element L is large, even if the diameter of the optical element L is equal to or less than the maximum diameter D1 between the supports (71 to 74) indicated by a two-dot chain line, There is a case where it reaches above the upper end of (71-74). In order to be able to store such an optical element L, the upper end (outer end 77 ′) of the support (71 to 74) must reach the upper end of the optical element L as shown by the broken line. As a result, the maximum diameter D3 between the supports (71 to 74) increases.

  When the diameter of the storage portion 5 formed on the substrate main body 31 increases from D1 to D3, the number of storage portions 5 that can be formed on the substrate main body 31 decreases.

  Therefore, in the second embodiment, as shown in FIG. 7, the upper front surface portion 76 of the first support body 71 to the fourth support body 74 is a first upper front surface whose inclination angle is δ1 (0 <δ1 <γ). The portion 761 and the second upper front surface portion 762 having an inclination angle of δ2 (γ <δ2 <90 degrees) are formed separately.

  The first upper front surface portion 761 is provided on the base end side of the support (71 to 74), and the second upper front surface portion 762 is provided on the front end portion side of the support (71 to 74) with the bending point KP as a boundary. Yes. And the diameter between each 2nd upper front part 762 is set to D1. Further, the height to the tip of the second upper front surface portion 762 is H2. The height of the bending point KP is, for example, about half of the height H2, but is not limited to this.

  According to the second embodiment, in FIG. 7, the optical element L having a large thickness is supported by the respective supports (71 to 74) by the first upper front surface portion 761. Since the inclination angle δ1 of the first upper front surface portion 761 is smaller than the inclination angle γ of the upper front surface portion 76 in the first embodiment, the support position of the optical element L is lowered. For this reason, the upper end of the optical element L becomes lower than the height H2. Therefore, the optical element L can be supported without increasing the outer diameter of the storage portion 5, and 20 optical elements can be stored as in the first embodiment.

  Further, when the support tray 1 is formed by the vacuum forming method, if the height of the lower front surface portion 76 is increased, the thickness of the support tray 1 is decreased accordingly, but the height of the lower front surface portion 76 is not increased. Therefore, the thickness of the support tray is not reduced, and sufficient strength and rigidity can be maintained.

  On the other hand, the lower front part 96 of each presser body (91 to 94) of the presser part 9 is also a first lower front part having an inclination angle δ1 on the side of the substrate body 31 with the bending point KP as a boundary, like the upper front part. 961, a second lower front surface portion 962 having an inclination angle δ2 is provided on the lower end side. The height H3 of each presser body (91 to 94) and the height of the folding point KP are the same as the height H2 and the folding point of the support body (71 to 74).

  Therefore, as in the first embodiment, the support tray 1 is arranged up and down, and the optical element L supported by the support pocket portion 7 of the support tray 1 arranged below is held by the support tray 1 arranged above. It can be pressed by the part 9.

  In the second embodiment, the first upper front surface portion 761 (first lower front surface portion 961) having a gentle inclination (inclination angle δ1) and the second upper front surface having a steep inclination (inclination angle δ2) with the bending point KP as a boundary. A portion 762 (second lower front surface portion 962) is formed on each of the upper and lower front surface portions 76 and 96 of the support body (71 to 74) and the presser body (91 to 94), but like a parabola indicated by a two-dot chain line The curved surface 11 may be used.

  In each of the above-described embodiments, the number of support bodies of the support pocket portion 7 and the number of presser bodies of the presser portion 9 has been described as four. However, the present invention is not limited to this, and three or five, etc. It is also good. When the outer diameter of the optical element L is small, the optical element L can be sufficiently supported even if the number of supports is three.

  Furthermore, although the number of pressers is the same as the number of supports (four), two pressers (first presser 91 and third presser 93, or second presser 92 and fourth presser) are opposed to each other. Only the presser body 94) may be used. In short, it is sufficient that the presser part 9 can press the optical element L supported by the support pocket part 7 without backlash.
