Description

  The present invention relates to a plate-shaped article package, a method for manufacturing the same, and a spacer, and more particularly to interposing a spacer between upper and lower adjacent plates when laminating a plurality of plate-like articles in the vertical direction. The present invention relates to the improvement of the structure and the improvement of the spacer therefor.

  As is well known, when packing (including packaging or packaging) a plate-like material represented by a glass plate such as a cover glass for an image sensor or a substrate for an optical filter, or a semiconductor wafer, a plurality of pieces in a horizontal posture are used. Arrangement in a stacked manner is performed by interposing a paper or resin spacer between the plate-like objects.

  As a specific example thereof, in Patent Document 1 below, the spacer includes a base frame portion and an outer frame portion, and the outer frame portion extends outward from the outer peripheral edge of the glass plate, and the base frame portion. The structure which provided the level | step-difference part to the outer frame part is disclosed. The base frame portion is interposed between the upper and lower glass plates, and the upper surface of the outer frame portion is configured to contact the lower surface of the outer frame portion of the spacer existing above.

  Furthermore, the spacer described in the same document has notches formed by notching outer frame portions at four locations on the outer peripheral edge, that is, four sides, and the presence of the notches allows the glass plate to be attached and detached. Care is taken to make it easier. That is, this spacer is for storing the glass plate in the upper surface side portion of the base frame portion and in the inner side portion of the outer frame portion, but because the outer frame portion is cut out at the above four locations. In these places, the outer side of the glass plate is not covered with the outer frame portion, and the peripheral edge portion of the glass plate is located on the outer side of the inner end portion of the notch portion.

Utility Model Registration No. 3054701

  By the way, according to the spacer disclosed in the above-mentioned Patent Document 1, since the peripheral edge portion of the glass plate is located on the outer side with respect to the inner end portion of the notch portion, for example, an operator holds the glass plate. When stacking on the spacer or pulling out from the spacer, the peripheral edge of the glass plate can be grasped by the operator's hand or finger through the notch, and the operation for grasping the glass plate can be easily performed. Become.

  That is, the notch portion of the spacer is formed only for the purpose of facilitating the gripping operation of the glass plate. And although this spacer can regulate the horizontal movement between the vertically adjacent spacers using the step part of the outer frame part, the posture of each spacer is not restricted, so the spacer and the glass plate For example, when the layers are stacked one after another, there is a possibility that the laminated body composed of the two may be inclined or fall down. However, the fact is that no countermeasures have been taken against such problems.

  Further, in the case of a spacer having such a configuration, when engaging adjacent spacers in the vertical direction, it is troublesome to perform the vertical movement and horizontal movement of each spacer smoothly and quickly with accuracy. Complicated work will be forced, and it will become a factor which causes work deterioration due to prolonged work and hence work efficiency.

  Furthermore, when producing a glass plate package using this spacer, it is necessary to take measures to prevent collapse etc. for a laminate in which a plurality of spacers and glass plates are alternately stacked. There is sex. In that case, if a complex method is not used, the effect of reinforcing the laminated body cannot be obtained sufficiently, and what measures should be taken to make the glass plate package strong by a simple method. How does it matter?

  The problems as described above are not limited to the glass substrate for liquid crystal display targeted by the spacer described in Patent Document 1, but a glass plate such as a cover glass for an image sensor or an optical filter substrate, a semiconductor wafer, or the like. Of course, this can happen.

  In view of the above circumstances, the present invention avoids tilting and falling of those laminates in the process of sequentially stacking spacers and plate-like objects, etc., and smoothing and speeding up the work in such processes, and A technical problem is to make it possible to manufacture a strong plate-like package by a simple method.

  The packing body according to the present invention, which was created to solve the above technical problem, is a plate formed by packing a plurality of plate-like objects stacked in the vertical direction with a spacer interposed between them. A laminated body having a spacer and a plate-like object, and a part or all of the outer peripheral edge of the spacer from the outer peripheral edge of the plate-like object. A plurality of notches are formed on the outer peripheral edge of the protruding portion so as not to interfere with the arrangement area of the plate-like material, and are fixed upright on the bottom plate. It is characterized in that a plurality of engaging members are respectively engaged with a plurality of notches of the spacer. Here, examples of the “plate-like object” include a glass plate such as a cover glass for an image sensor and a substrate for an optical filter, or a semiconductor wafer.

  According to such a configuration, under the state where the spacers and the plate-like object are alternately stacked above the bottom plate, a part or all of the outer peripheral edge portion of the spacer is outward from the outer peripheral edge portion of the plate-like object. A plurality of notches are formed at the outer peripheral edge of the protruding portion so as not to interfere with the arrangement area of the plate-like object. In other words, the spacer is formed such that the inner end portion of each notch portion formed on the outer peripheral edge portion of the protruding portion is positioned on the outer side of the outer peripheral edge portion of the plate-like object. ing. Since the plurality of engaging members erected on the bottom plate are respectively engaged with the plurality of notches formed in the spacer, collapse of the laminated body is prevented by the engaging members, and the Thus, the plate-shaped package becomes strong, and the movement of each spacer (laminated body) around the central axis is also restricted by the engaging member, thereby preventing unreasonable movement of the laminated body. Furthermore, when manufacturing this plate-shaped article package, the notch portion of the spacer is engaged with the engaging member and the spacer is accommodated above the bottom plate, and the plate-like article is engaged thereabove. Since the housing operation is performed alternately without interfering with the member, each spacer can be smoothly and quickly accommodated at an accurate position in the horizontal direction without inclining or falling due to the presence of the engaging member. become.

  In this case, it is preferable that the top of the laminate is covered with a top plate.

  If it does in this way, it will become possible to obtain the plate-shaped package which is appropriately protected not only below but also above the laminate.

  Further, three or more notches are formed in the outer peripheral edge of the protruding portion of the spacer, and an angle between two straight lines connecting all two adjacent notches and the center of the spacer is 180 °. It is preferable to configure so as to be less than.

  If it does in this way, since the circumference of each spacer will be in the state where it was restrained and supported by the engagement member, and each spacer is prevented from detaching from the engagement member, each spacer (laminated body) is horizontal in all directions. The movement does not occur, and it becomes possible to obtain an even stronger plate-like package.

  On the other hand, the method according to the present invention, which was created to solve the above technical problem, is packed with a plate-like material interposed between each of a plurality of plate-like materials stacked in the vertical direction. A plurality of engaging members are erected and fixed to the bottom plate so as to surround a laminated region existing above the bottom plate, and formed on the outer peripheral edge of the spacer. In the state where the plurality of notches are engaged with the plurality of engagement members, the spacer is accommodated in the stacked region, and the plate is not interfered with the plurality of engagement members. It is characterized in that the accommodation of the objects in the laminated region is alternately performed a plurality of times.

  According to such a method, the notch portion of the spacer is engaged with the engagement member, and the spacer is accommodated in the lamination region above the bottom plate, and the plate-like object is laminated without interfering with the engagement member. The stacking operation is completed by alternately performing the operation of accommodating in the region over a plurality of times. In this case, each spacer is guided by the engaging member and is accommodated in a precise position in the horizontal direction in the stacking region. Therefore, the stacking operation is facilitated and speeded up. Since the tilt and the tilt do not occur, the operation is stabilized.

  In this method, it is preferable that the top plate is covered over the laminated body after the spacer and the plate-like object are completely accommodated in the laminated region and the laminated body is formed.

  If it does in this way, it will become possible to obtain the plate-shaped package which is appropriately protected not only below but also above the laminate.

  In addition, the spacer according to the present invention, which was created to solve the above technical problem, is a spacer that is interposed between adjacent plate-like materials when a plurality of plate-like materials are stacked in the vertical direction. In the outer peripheral edge of the spacer, a plurality of notches are formed that can engage with a plurality of engaging members that surround the periphery of the spacer without interfering with the plate-like object and extend in the vertical direction. It is characterized by having done.

  According to such a configuration, the plurality of engaging members that surround the periphery and extend in the vertical direction can be engaged with the plurality of notches formed in the spacer without interfering with the plate-like object. Therefore, it is possible to appropriately reinforce the spacers (laminates) by using the engaging members, and to strengthen the plate-shaped package, and the center of each spacer. The movement can also be restricted by the engaging member, so that an inappropriate movement of the laminate can be prevented. Furthermore, when manufacturing a plate-shaped article package using this spacer, an operation of engaging the notch portion of the spacer with the engaging member to receive the spacer, and the plate-like article with the engaging member Therefore, the spacers can be accommodated smoothly and quickly at an accurate position in the horizontal direction without causing inclination or falling.

  In this spacer, three or more notches are formed, and the angle between two straight lines connecting all two adjacent notches and the center of the spacer is less than 180 °. It is preferable.

  Even in this case, the periphery of each spacer is restrained and supported by the engaging member, and the spacer is prevented from being detached from the engaging member. No horizontal movement occurs, and it becomes possible to obtain a more robust plate-like package.

  Further, the spacer can be configured to include a restricting portion that is formed on the upper surface side portion of the support portion that supports the outer peripheral edge portion of the plate-like object from below and restricts the lateral movement of the plate-like object. . Here, the “lateral direction” means a direction orthogonal to the stacking direction (vertical direction) of the plate-like objects (hereinafter the same).

  If it does in this way, the horizontal movement of a plate-shaped object will be controlled by the control part of a spacer, and a plate-shaped object will be in the state which can be appropriately positioned on the support part of a spacer.

  In addition, this spacer is an upper member that performs lateral positioning with the upper spacer on the upper surface side portion of the portion spaced outward from the support portion that supports the outer peripheral edge of the plate-like object from below. While forming a joint part, it can be set as the structure which formed in the lower surface side part of the formation site | part of the said upper engaging part the lower side engaging part which performs lateral positioning between the spacers which exist below.

  In this way, the support portion that supports the plate-like object from below, and the upper engagement portion and the lower engagement portion that perform the lateral positioning of the vertically adjacent spacers are formed in separate portions in the inner and outer directions. Therefore, the lateral positioning of the spacer is performed in a state independent of the support of the plate-like object. Therefore, it is possible to avoid the mutual influence of the roles of the two and to reliably perform the respective roles.

  Moreover, this spacer can be comprised as a circular frame-shaped body which supports a circular plate-shaped object.

  If it does in this way, it will become possible to aim at weight reduction and a saving of material, after aiming at a circular plate-shaped object. In addition, since the center portion of the plate-like object does not come into contact with the frame-like body, it is possible to prevent the occurrence of scratches and the like due to contact with the frame-like body.

  In the above configuration, from the viewpoint of protecting the plate-like object with appropriate rigidity, the spacer is preferably formed of a resin, and from the viewpoint of sufficiently securing the above-described effects, the plate-like object is a glass plate. It is preferable that

  As described above, according to the present invention, a plurality of engagement members that surround the periphery and extend in the vertical direction can be engaged with the plurality of notches formed in the spacer without interfering with the plate-like object. Therefore, it is possible to perform appropriate reinforcement capable of preventing collapse of each spacer (laminated body) by the engaging member, and it is possible to make the plate-like package strong and to make the center of each spacer The movement around can be restricted by the engaging member, so that the unfair movement of the laminate can be prevented. Furthermore, when manufacturing a plate-shaped article package using this spacer, an operation of engaging the notch portion of the spacer with the engaging member to receive the spacer, and the plate-like article with the engaging member Since the operation of accommodating without interfering is performed alternately, each spacer can be accommodated smoothly and quickly at an accurate position in the horizontal direction without causing inclination or falling.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. Fig.1 (a) is a top view which shows the whole structure of the spacer which concerns on 1st Embodiment of this invention, FIG.1 (b) is AA sectional drawing of Fig.1 (a).

  As shown in FIGS. 1A and 1B, the spacer 1 according to the present embodiment has a substantially circular frame shape, and is roughly divided into an inner frame portion positioned on the innermost side (inner circumferential side). 1A, an intermediate frame portion 1B provided continuously on the outer side (outer peripheral side) thereof, and an outer frame portion 1C provided continuously on the outer peripheral side thereof, which are integrally formed. And the periphery of the outer peripheral side area of the inner frame portion 1A (in the present embodiment, the portion formed by the outer peripheral side region of the inner frame portion 1A and the inner peripheral side region of the intermediate frame portion 1B) is the periphery of the circular glass plate G. The support part 2 which supports a part (outer peripheral edge part) from the lower side is provided, and the upper frame engagement part 3 and the lower engagement part that perform lateral positioning between the spacers 1 adjacent to each other in the vertical direction are provided on the outer frame part 1C. 4 is provided. Further, as shown in FIG. 1B, the support portion 2 is formed with a restricting portion 5, a receiving portion 6, and a pressing portion 7, and the upper engaging portion 3 is provided with an upper step portion 3a. In addition, the lower engaging portion 4 is provided with a lower stepped portion 4a. The material of the spacer 1 is polypropylene, polycarbonate, ABS resin or the like, and the glass plate G is a glass plate such as a cover glass for an image sensor or an optical filter substrate.

  FIG. 2 is a longitudinal sectional view showing a part of a state in which the spacer 1 and the glass plate G are laminated, and the cross section of the spacer 1 is not hatched for convenience. As shown in the figure, the upper surface side portion of the support portion 2 of the spacer 1 has a stepped portion between the inner peripheral side end portion of the intermediate frame portion 1B and the outer peripheral side end portion of the inner frame portion 1A at the lower position. In addition, a restricting portion 5 is provided that can be brought into contact with the end face Ga of the glass plate G. The restricting portion 5 is a restricting surface (cylindrical surface) parallel to a vertical line extending to a position lower than the bottom surface Gb of the glass plate G. 5a. And this control surface 5a is comprised so that the force of only the direction substantially orthogonal to the end surface Ga from the end surface Ga of the glass plate G may be received. In a normal state, a predetermined gap is provided between the regulation surface 5a and the end surface Ga of the glass plate G.

  Furthermore, the upper surface side portion of the support portion 2 of the spacer 1 is provided with a receiving portion 6 that comes into contact with a portion separated from the end surface Ga of the bottom surface Gb of the glass plate G by a predetermined dimension on the inner peripheral side. It has a circular cross section (semi-circular cross section) and is substantially in line contact with the bottom surface Gb of the glass plate G. Therefore, the weight of the glass plate G is properly received from below by the receiving portion 6. In addition, the contact part with the receiving part 6 of the glass plate G exists in the area | region of the outer peripheral side rather than the effective surface of the glass plate G. FIG.

  And since the area | region between the control part 5 and the receiving part 6 is dented and has comprised concave shape, in this area | region, the corner | angular part Gc between the end surface Ga of the glass plate G and the bottom-surface peripheral part Gba is formed. The contact portion 2 cannot be brought into contact with the upper surface side portion of the support portion 2. Moreover, in the region between the restricting portion 5 and the receiving portion 6, the bottom surface Gb of the glass plate G cannot be brought into contact with the upper surface side portion of the support portion 2. Accordingly, the glass plate G can be brought into contact with the upper surface portion of the support portion 2 of the spacer 1 only in two places, that is, the restriction portion 5 and the receiving portion 6.

  Further, on the lower surface side portion of the formation portion of the receiving portion 6 in the spacer 1, there is provided a pressing portion 7 that comes into contact with a portion that is separated from the end surface Ga on the upper surface Gd of the glass plate G that exists below by a predetermined dimension on the inner peripheral side. Yes. The pressing portion 7 also has an annular shape with a circular cross section (semi-circular cross section), is formed with a uniform height over the entire portion, and is substantially in line contact with the upper surface Gd of the glass plate G. In other words, the presser portion 7 is formed so as to be vertically symmetrical with the receiving portion 6. And since the area | region from the inner peripheral side edge part of the intermediate | middle frame part 1B in the lower surface side part of the spacer 1 to the presser part 7 is dented and has comprised concave shape, also about the upper surface Gd of the glass plate G, its end surface Ga In the region from the first part to the part where the presser part 7 contacts, the lower surface side portion of the spacer 1 cannot be contacted.

  Further, the upper engaging portion 3 and the lower engaging portion 4 of the spacer 1 are both formed at a portion spaced from the support portion 2 by a predetermined dimension on the outer peripheral side, and the upper engaging portion 3 has an upper spacer 1. An upper step portion 3a for lateral positioning with respect to the upper step portion 3a is formed, and a lower step portion for lateral positioning with the spacer 1 located below is formed on the lower surface side portion of the upper step portion 3a. 4a is formed. Accordingly, the upper step portion 3a and the lower step portion 4a are formed in a portion separated from the support portion 2 by a predetermined dimension on the outer peripheral side.

  In addition to the above configuration, the spacer 1 has a missing portion 8 formed symmetrically on both the left and right sides, as shown in FIG. The both missing portions 8 are formed by cutting a circular portion into a straight line so as to be the same length in parallel on both the left and right sides, and a portion including the receiving portion 6 and the regulating portion 5 is missing, and the inner frame portion 1A. The inner peripheral side portion of the receiving portion 6 is provided with an extending portion 9 that extends in the inner peripheral direction. The inner peripheral side edge of the extending portion 9 is formed in a straight line parallel to the outer peripheral side edge of the missing portion 8. The extending portion 9 plays a role for reinforcing the missing portion 8.

  Under the state in which the circular glass plate G is supported on the support portion 2 of the spacer 1, the left and right side portions (Ge) of the glass plate G are both missing portions 8 of the spacer 1 as indicated by chain lines in FIG. It will be in the state which protruded in the outer peripheral direction from the linear outer peripheral side edge. More specifically, in a state where the glass plates G are stacked on the spacer 1, the first region B1 where the outer contour line of the spacer 1 is located on the outer peripheral side with respect to the outer contour line of the glass plate G in the plan view is on both front and rear sides. In addition to being provided, second regions B <b> 2 in which the outer contour line of the glass plate G is located on the outer peripheral side of the outer contour line of the spacer 1 are provided on both left and right sides. Accordingly, in the first region B1, the outer peripheral edge of the spacer 1 protrudes outward from the outer peripheral edge of the glass plate G, and in the second region B2, the outer peripheral edge of the glass plate G is the outer peripheral edge of the spacer 1. It is in a state where it has erupted outward.

  Furthermore, on the left and right sides having the second region B2, the outermost portion Ge in the left-right direction of the glass plate G is located on the outer side in the left-right direction with respect to the outermost portion 1E in the left-right direction of the spacer 1. ing. In the second region B2, the spacer 1 is missing a portion including the upper engaging portion 3, the lower engaging portion 4, the restricting portion 5, the receiving portion 6, and the holding portion 7, and only the extending portion 9 is present. Existing. Therefore, for the operation of fitting the glass plate G to the support portion 2 of the spacer 1 and the operation of extracting the glass plate G, for example, the operator applied three fingers to the outermost portion Ge in the left-right direction of the glass plate G. Can be easily done in the state.

  Further, the arcuate outer peripheral edge portion (the portion corresponding to the first region B1) excluding both the missing portions 8 of the spacer 1 includes a total of two locations on the front side and two locations on the rear side. A semicircular cutout 10 is formed at four locations in plan view. These notches 10 are formed in a state where the inner peripheral side portion including the restricting portion 5 is left. The angles β1, β2, β3, and β4 between two straight lines connecting all two adjacent notches 10 and the center X of the spacer 1 are less than 180 ° (for example, all 90 °).

  FIG. 3 is a perspective view showing a glass plate package 11 in which the spacer 1 having the above configuration is interposed between a plurality of horizontal glass plates G and stacked in a vertical direction for packing. It is. As shown in the figure, this glass plate package 11 has a pin member 13 that is four engaging members fixed upright on a bottom plate (lower surface plate) 12, and four arc-shaped outer peripheral edge portions of the spacer 1. The notch 10 formed at the location is engaged, the glass plate G is supported on the support 2 of the spacer 1, and the spacer 1 and the adjacent spacer 1 are connected to the upper engaging portion 3 of both. And the lower engagement portion 4 are engaged and sequentially stacked. Therefore, the laminated body 15 in which the spacers 1 and the glass plates G are alternately arranged is placed in the laminated region S1 formed by being surrounded by the four pin members 13 above the bottom plate 12. ing. The pin member 13 is a rod-shaped body having a circular cross section.

  An upper surface plate 14 serving as a top plate is covered on the uppermost spacer 1 so as to be fixed to the upper end portions of the four pin members 13. In addition, four holes (which may be four through holes penetrating the top plate 14) through which the upper end portions of the four pin members 13 are inserted are formed in the lower surface portion of the top plate 14. Under this state, since the top plate 14 is in a state of pressing the spacers 1 of the laminated body 15 from above, the upper step of the upper engaging portion 3 of the spacer 1 located below among the vertically adjacent spacers 1. The portion 3a and the upper end surface 3b are in close contact with the lower stepped portion 4a and the lower end surface 4b of the lower engaging portion 4 of the spacer 1 located above (see FIG. 2). Therefore, the upper engaging portion 3 and the lower engaging portion 4 of the spacer 1 can perform not only horizontal positioning of the vertically adjacent spacers 1 but also vertical positioning.

  In order to manufacture the glass plate package 11 described above, first, the bottom plate 12 on which the four pin members 13 are erected and fixed so as to surround the laminated region S1 is placed on the floor surface or the like. Under such a state, the spacer 1 is accommodated in the stacked region S1 in a horizontal posture by engaging each notch 10 with the four pin members 13 from above. Next, the glass plate G is accommodated in a horizontal posture in the stacked region S <b> 1 without causing interference with the pin member 13. And the accommodation of the spacer 1 and the accommodation of the glass plate G are alternately performed a plurality of times, and when the laminated body 15 reaches a predetermined height, that is, when a predetermined number of glass plates G are laminated, The top plate 14 is placed above the laminated body 15 and pressed downward. Finally, the laminated body 15 is interposed between the bottom plate 12 and the top plate 14 and is held in a state in which the periphery is restrained by the pin member 13 using a binding band, a shrink film, a clip, or the like. To do. Preferably, they are housed inside the outer box in order to protect them from external impacts and dirt.

  As described above, according to the glass plate package 11 manufactured using the spacer 1 according to this embodiment, the four notches 10 formed in the spacer 1 are erected and fixed to the bottom plate 12. Since the four pin members 13 are engaged, an appropriate reinforcing effect that can prevent the laminated body 15 from collapsing can be obtained, the glass plate package 11 can be made strong, and each spacer 1 The movement around the center X of the laminated body 15 is restricted, so that an inappropriate movement of the laminated body 15 can be prevented. Further, when the glass plate package 11 is manufactured using the spacer 1, the operation of receiving the spacer 1 by engaging the notch 10 of the spacer 1 with the pin member 13, and the glass plate G Since the operation of accommodating without interfering with the pin member 13 is alternately performed, each spacer 1 can be accommodated smoothly and quickly at an accurate position in the horizontal direction without causing inclination or falling. Become.

  In addition, according to the spacer 1 which concerns on this embodiment, the effect as shown below can also be acquired. That is, if packing is performed by interposing the spacer 1 between each of a plurality of glass plates G in a horizontal posture, the glass plate G moves in the horizontal direction when the glass plate package 11 is transported. Even though the bottom surface Gb and the top surface Gd of the glass plate G slide with the receiving portion 6 and the holding portion 7 of the spacer 1, the corner portion Gc between the end surface Ga and the bottom surface peripheral portion Gba of the glass plate G is a spacer. The end face Ga stays in contact with the regulating surface 5 a of the spacer 1 without sliding with any surface of the upper surface portion of 1. As a result, dust generation due to sliding of the corner portion Gc of the glass plate G with the upper surface side portion of the spacer 1 is suppressed, and adhesion of foreign matter to the upper surface of the glass plate G caused by this dust generation and difficulty of cleaning are prevented. Is avoided.

  Each spacer 1 includes a support portion 2 that supports the peripheral portion of the glass plate G from below, and an upper engagement portion 3 and a lower engagement portion 4 that perform lateral positioning of the spacers 1 adjacent to each other vertically. Since the spacers 1 are formed at different locations in the inner and outer directions, the lateral positioning of the spacer 1 is performed in a state independent of the support of the glass plate G. Therefore, the lateral positioning of the spacer 1 and the support of the glass plate G are avoided from affecting each other, and each role can be reliably played.

  Further, in a state where the glass plates G are stacked on the spacer 1, the outermost portion Ge in the left-right direction of the glass plate G in the plan view is more lateral than the outermost portion 1 E in the left-right direction of the spacer 1. Since the glass plate G is fitted into and removed from the support portion 2 of the spacer 1, the outermost portion Ge in the left-right direction of the glass plate G is determined by, for example, an operator. It can be carried out with a finger, and the outermost part 1E of the spacer 1 is prevented from interfering with the worker during this work, so that workability or work efficiency is improved.

  4 is a longitudinal sectional view (a view corresponding to FIG. 2 described above) showing a part of a state in which the spacer 1 and the glass plate G according to the second embodiment of the present invention are laminated. For the sake of convenience, hatching is omitted for the cross section. The spacer 1 according to the second embodiment is different from the spacer 1 according to the first embodiment described above in that the restricting portion 5 formed on the upper surface side portion of the support portion 2 protrudes toward the inner peripheral side. The upper surface side portion of the spacer 1 is formed such that the entire area of the regulation surface 5a formed at the tip of the convex portion can be brought into contact with only the central region in the vertical direction of the end surface Ga of the glass plate G. In addition, a concave portion (relief portion) 19 having a circular cross section is formed so that it cannot be brought into contact with the peripheral end surface Ga and the bottom surface peripheral edge portion Gba including the corner portion Gc of the glass plate G, and the inner frame portion 1A. The upper surface side portion of the inner frame portion is inclined downward from the receiving portion 6 toward the inner peripheral side, and the lower surface portion of the inner frame portion 1A is inclined upward from the presser portion 7 toward the inner peripheral side. is there. In addition, about the same component as the spacer 1 which concerns on the above-mentioned 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  And also about the spacer 1 which concerns on this 2nd Embodiment, a total of four notch parts 10 are formed in the circular-arc outer peripheral part of the spacer 1 similarly to the form shown in FIG. As in the embodiment shown in FIG. 3, the four notches 10 of the spacer 1 are engaged with the four pin members 13 that are erected and fixed to the bottom plate 12, and without interfering with the pin members 13. The glass plate G is stacked on the spacer 1, and the top plate 14 is covered on the upper end portion of the laminate 15, whereby the basic configuration of the glass plate package 11 is obtained. Therefore, even when the glass plate pack 11 is manufactured using the spacer 1 according to the second embodiment, the same effects as those of the first embodiment can be obtained.

  In addition, according to the structure of the spacer 1 which concerns on this 2nd Embodiment, when the glass plate G moves to a horizontal direction, only the end surface Ga except the corner | angular part Gc of the glass plate G is only the control part 5 (control surface 5a. ), The corner portion Gc of the glass plate G does not rub against the upper surface side portion of the spacer 1, and also when the end surface Ga of the glass plate G contacts the restricting portion 5. The corner part Gc of the glass plate G cannot be a problem. Therefore, it is possible to more reliably avoid the problem of dust generation and foreign matter adhesion and cleaning caused by this.

  In this case, in the first and second embodiments, the present invention is applied when a part of the outer peripheral edge of the spacer 1 protrudes outward from the outer peripheral edge of the glass plate G. However, the present invention can be similarly applied to the case where the entire outer peripheral edge portion of the spacer 1 protrudes outward from the outer peripheral edge portion of the glass plate G.

  In addition, the spacer 1 according to the first and second embodiments described above is formed by forming notches at four locations on the outer peripheral edge, but instead of this, notches are provided at three locations or five or more locations.
