Description

  The present invention relates to a storage box for storing a plate-shaped article.

  For flat panel displays such as plasma displays and liquid crystal displays, glass substrates in which electronic elements such as semiconductor elements and various thin films are formed on a glass plate are used. Damage and contamination of the glass substrate cause malfunction of the flat panel display. Therefore, for example, when a glass substrate is stored, the glass substrate is stored in a box or the like for the purpose of preventing damage to the glass substrate and contamination due to dust or the like.

  As a conventional technique corresponding to the storage box of the present invention, Patent Document 1 discloses a rectangular tube shape in which a pair of side plates parallel to each other are provided between a ceiling plate and a bottom plate that are arranged in parallel with a space in the vertical direction. A glass substrate storage box is shown. The glass substrate storage box is provided so that the side plate can be displaced around the vertical axis at the end on the back side of the side plate, and the side plate is provided so that the end on the near side which is the opening side for inserting the glass substrate is opened. On the inner surface, a plurality of support grooves extending in the horizontal direction from the near side to the far side are formed side by side. In the configuration of the glass substrate storage box, the glass substrate is stored so as to fit into the support groove.

  As another conventional technique corresponding to the storage box of the present invention, Patent Document 2 discloses a glass plate transport box having a box body made of a foamed resin molded body and a pad. The glass plate transport box is provided with a pair of opposing side surface pads inside the box body. Each pad has a groove into which the end of the glass plate is fitted. The glass plate transport box is stored with the glass plate fitted in each groove.

  As another conventional technique corresponding to the storage box of the present invention, Patent Document 3 discloses a container for storing a plurality of glass plates side by side. A container has the sheet | seat for cushions which consists of a polypropylene or polyethylene interposed between each glass plate, and is comprised so that glass plates may not mutually contact.

Japanese Unexamined Patent Publication No. 4-267777 JP 2001-31165 A JP 2003-226354 A

  In the configuration of the glass substrate storage box disclosed in Patent Document 1, when the glass substrate is inserted into the support groove and inserted, the opening side plates can be moved away from each other and opened. Therefore, when the glass substrate is inserted, the glass substrate is not guided along the support groove, and only the portion on the downstream side in the insertion direction of the glass substrate may be inserted while being guided by the support groove. In such a case, the glass substrate and the support groove come into contact with each other with a smaller contact area as compared with the case where the entire end portion in the direction perpendicular to the insertion direction is in contact with and inserted into the support groove. Therefore, a large external force acts locally on the glass substrate, and the glass substrate may be cracked or chipped.

  In the configuration of the glass plate transport box shown in Patent Document 2, it must be inserted and stored against the frictional resistance generated between the pad and the glass plate, and an undesired external force is applied to the glass plate. There is a possibility that the glass plate is cracked or chipped.

  In the configuration of the container described in Patent Document 3, a cushion is interposed between the glass plates so that the glass plates do not come into contact with each other, but this is not a configuration that prevents displacement of the glass plates in the container. . Therefore, the glass plate may be displaced in a direction perpendicular to the thickness direction by vibration such as when the container is transported, and the glass plate may collide with the container, and the glass plate may be cracked or chipped.

  The objective of this invention is providing the storage box which can prevent that a plate-shaped to-be-stored item is damaged.

The present invention includes a box body in which a plate-shaped object is inserted in an insertion direction and is disposed and stored in a storage area;
It has flexibility and elasticity, and includes a guide holding means for guiding the plate-shaped article to a predetermined storage area and resiliently holding the plate-shaped article in the storage area. It is a storage box.

  According to the present invention, the storage box has flexibility and elasticity, guides the plate-like object to be stored in a predetermined storage area, and elastically holds the glass plate in the storage area. With. Since the guide holding means is flexible, it can be guided in accordance with the size of the plate-shaped stored object when the plate-shaped stored object is inserted. Therefore, when the plate-shaped article collides with the guide holding means, the guide holding means is deformed and the impact force can be reduced. Further, since the guide holding means has elasticity, it itself deforms in accordance with the plate-shaped object, so that it can be guided without applying a large external force to the plate-shaped object. Accordingly, it is possible to prevent the plate-shaped stored object from being damaged by an external force applied when the plate-shaped stored object is inserted into the storage box.

  Further, the guide holding means elastically holds the plate-shaped object to be stored, so that even when the storage box receives an impact force, the impact force is absorbed by the guide holding means. Thereby, it is possible to prevent the impact force from acting on the plate-shaped storage object and to prevent the plate-shaped storage object from being damaged.

In the present invention, the box includes a peripheral wall that opens to at least one of the boxes.
The guide holding means is provided on the peripheral wall and is elastically deformed so that the tip side portion can be retracted, the tip side portion surface is formed smoothly, and the tip side portion abuts on the plate-shaped object. The plate-shaped stored object is guided and held.

  According to the present invention, the guide holding means can be elastically deformed and the tip side portion can be retracted. Accordingly, it is possible to realize a guide that matches the size of the plate-shaped stored object when the plate-shaped stored object is inserted. Further, the surface of the tip end portion is formed smoothly. As a result, the frictional force generated between the glass plate and the abutment surface of the guide holding means can be reduced when the plate-shaped object is inserted into the storage box. Therefore, since the external force which a plate-shaped stored object receives when inserting in a storage box can be made small, it can prevent that a plate-shaped stored object is damaged.

  Further, the present invention is characterized in that the guide holding means guides and holds the plate-shaped stored object by elastically abutting the plate-shaped stored object on the surface in the thickness direction.

  According to the present invention, the guide holding means elastically abuts the plate-shaped article to the surface in the thickness direction, so that at least the plate-shaped article is elastically held in the thickness direction. Thereby, it is possible to prevent the plate-shaped object from being displaced in the storage box. Therefore, even when a plurality of plate-shaped objects are stored in the storage box, the plate-shaped objects can be prevented from colliding with each other, and the plate-shaped objects can collide with the storage box. Can be prevented.

  Further, the present invention is characterized in that the guide holding means guides and holds the plate-shaped stored object by elastically abutting the plate-shaped stored object on the surface in the direction perpendicular to the thickness direction.

  According to the present invention, the guide holding means elastically abuts the plate-shaped article to the surface in the direction perpendicular to the thickness direction, so that at least the plate-shaped article is elastically projected in the direction perpendicular to the thickness direction. Pinch. Thereby, it is possible to prevent the plate-shaped object from being displaced in the storage box. Therefore, even when a plurality of plate-shaped objects are stored in the storage box, the plate-shaped objects can be prevented from colliding with each other, and the plate-shaped objects can collide with the storage box. Can be prevented.

  In the invention, it is preferable that the guide holding means is formed with a groove portion that extends in the insertion direction of the plate-shaped storage object and into which the plate-shaped storage object is fitted.

  According to the present invention, when a plate-shaped article is inserted, it can be inserted along the groove. As a result, it is possible to prevent the plate-shaped object from being inserted into the storage box in a state shifted in the direction perpendicular to the insertion direction, so that the plate-shaped object collides with the box during the insertion operation. Damage can be prevented. In addition, since the plate-shaped object is fitted into the groove, it is possible to prevent the plate-shaped object from being displaced in the thickness direction due to vibration or the like.

  In the present invention, the groove portion is formed such that the width dimension of the upstream portion of the plate-shaped stored object in the insertion direction is larger than the width dimension of the downstream portion of the plate-shaped stored object in the insertion direction. And

  According to this invention, the dimension of the width direction of the insertion direction upstream of a groove part is formed larger than the width dimension of the part of the insertion direction downstream of a plate-shaped stored article. Accordingly, the plate-shaped storage object can be easily inserted into the groove portion, and the insertion work for inserting the plate-shaped storage object into the storage box is facilitated.

In the invention, it is preferable that the guide holding means is a plate-like member having an elastic coefficient of 1.0 × 10 ⁴ kg / cm ² or more and 10 ⁶ kg / cm ² or less.

According to the present invention, even when the storage box is subjected to an external impact, the plate-shaped stored object is not displaced, and scratches or the like are generated on the surface of the plate-shaped stored object. Can be prevented. When the elastic modulus of the guide holding means is less than 1.0 × 10 ⁴ kg / cm ² , the plate-like storage object is displaced from the guide holding means, so that the plate-like storage object collides with the box. There is a risk. Further, when the elastic modulus of the guide holding means exceeded 10 ⁶ kg / cm ² , there was no displacement between the abutting member and the glass plate, but the surface of the plate-shaped storage object at the abutting portion was abraded. There is a risk of leaving marks. Since the guide holding means has an elastic coefficient of 1.0 × 10 ⁴ kg / cm ² or more and 10 ⁶ kg / cm ² or less, even if the storage box receives an external impact, it is stored in a plate shape. It is possible to prevent the object from being displaced, and to prevent a scratch mark or the like from being generated on the surface of the plate-shaped object.

Further, the present invention is provided with a displacement prevention means for preventing the displacement of the plate-shaped storage object arranged in the storage area,
The displacement prevention means is
It is provided so as to be displaceable over a support position downstream in the insertion direction with respect to the storage area and a receiving position upstream of the support position in the insertion direction, and is arranged in the support position in the insertion direction of the plate-shaped storage object. A support portion for preventing the displacement of
A plate-shaped object to be stored in a state in which it is displaceably provided between a holding position facing the storage area from a direction perpendicular to the insertion direction and a holding release position retracted in a direction away from the storage area from the holding position. A clamping part that abuts the end surface of the object and clamps the plate-shaped stored object;
The support portion is arranged such that the holding portion is arranged at the holding position, the holding portion is arranged at the holding position, and the holding portion is arranged at the receiving position, and the holding portion is arranged at the holding release position. It has an interlocking mechanism for interlocking with the clamping part.

  According to the present invention, the holding unit is arranged at the holding position, the holding unit is arranged at the holding position, and the holding unit is arranged at the receiving position, and the holding unit is arranged at the holding release position. As described above, the support portion and the sandwiching portion are interlocked. The sandwiching portion does not sandwich the plate-shaped stored object until the plate-shaped stored object is disposed at a support position where displacement in the insertion direction is prevented. In this way, in the operation of inserting and storing the plate-shaped object to be stored in the storage box, the clamping portion does not rub against the surface of the plate-shaped object. Therefore, it is possible to prevent the surface of the glass substrate from being damaged during the insertion operation, and it is possible to reliably hold the plate-shaped storage object in the storage position by being fixed by the holding portion.

  Further, the present invention is characterized in that the abutting portion that abuts at least the plate-shaped object of the clamping portion has an Asker C hardness of 30 ° or more and 70 ° or less.

  According to the present invention, even when vibration is applied to the storage box, the plate-shaped storage object does not collide with the box or the like, and the plate-shaped cover is caused by the contact of the contact member. Damage to the stored items can be reliably prevented. If the Asker C hardness of the abutting portion is less than 30 °, the plate-shaped stored object cannot be fixed, and the plate-shaped stored object may collide with a box or the like due to vibration during transportation or the like, and may be damaged. When the Asker C hardness exceeds 70 °, the elastic body becomes too hard, and there is a risk of damaging the plate-shaped stored object when the contact portion contacts the plate-shaped stored object. Since the contact portion that contacts the plate-shaped object has an Asker C hardness of 30 ° or more and 70 ° or less, even if vibration is applied to the storage box, the plate-shaped object is a box or the like. There is no collision, and damage to the plate-shaped stored object due to the contact of the contact member can be reliably prevented.

  ADVANTAGE OF THE INVENTION According to this invention, it can prevent that a plate-shaped storage thing is damaged by the external force added when inserting a plate-shaped storage thing into a storage box. Even when the storage box receives an impact force, the impact force is absorbed by the guide holding means. Thereby, it is possible to prevent the impact force from acting on the plate-shaped storage object and to prevent the plate-shaped storage object from being damaged.

  Moreover, according to this invention, since the external force which a plate-shaped stored object receives when inserting in a storage box can be made small, it can prevent that a plate-shaped stored object is damaged.

  Further, according to the present invention, even when a plurality of plate-shaped objects are stored in the storage box, the plate-shaped objects can be prevented from colliding with each other. Colliding with the storage box can be prevented.

  Further, according to the present invention, even when a plurality of plate-shaped objects are stored in the storage box, the plate-shaped objects can be prevented from colliding with each other. Can be prevented from colliding with the storage box.

  FIG. 1 is a perspective view of a storage box 1 according to an embodiment of the present invention. The storage box 1 is used for storing a plate-shaped article such as a glass substrate used for a glass plate and a flat panel display, for example.

  The storage box 1 has a plate body 2 into which a plate-shaped storage object is inserted in the insertion direction and is disposed and stored in a storage area. The storage box 1 has flexibility and elasticity, and the plate-shaped storage object is Guiding and holding means that guides the storage area and elastically holds the plate-shaped object in the storage area.

  The box body 2 includes a peripheral wall 4 that opens to at least one side. Specifically, the box 2 of the present embodiment includes a peripheral wall 4 and a bottom wall, the peripheral wall 4 is open on one side and has an opening 3, and the other side is connected to a flat rectangular plate-shaped bottom wall, The other side is blocked. More specifically, the peripheral wall 4 has a flat rectangular plate-shaped first peripheral wall portion 5 and second peripheral wall portion 6, as well as a third peripheral wall portion 7 and a fourth peripheral wall portion 8, and the first peripheral wall portion 5 and the first peripheral wall portion 5. The two peripheral wall portions 6 are square cylinders facing each other, and the third peripheral wall portion 7 and the fourth peripheral wall portion 8 are facing each other. Further, the storage box 1 of the present embodiment includes a flat rectangular lid 9 that closes the opening 3.

  A groove 11 (hereinafter also referred to as “box groove”) 11 extending from the opening 3 of the box 2 to the bottom wall is formed on the inner surface portion 10 of the peripheral wall 4. In the present embodiment, a plurality of box groove portions 11 are formed in the first peripheral wall portion 5 and the second peripheral wall portion 6. The box groove portions 11 facing each other in a pair formed on the first peripheral wall portion 5 and the second peripheral wall portion 6 are formed so as to extend in parallel to each other. The box 2 is formed with a storage space that is a space surrounded by the box groove 11 and the bottom wall.

The guide holding means is formed of a contact member 12 having flexibility and elasticity, for example. The contact member 12 is formed, for example, by a sheet made of resin formed in a plate shape (hereinafter also referred to as “resin sheet”). The abutting member 12 is formed by bending the resin sheet into an arch shape so as to protrude toward the inside of the box 2 in the box groove 11 that forms a pair. Examples of the resin sheet include polyolefin resins such as polyethylene and polypropylene, polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polyamide resins such as nylon-6 and nylon-66, and fluorine resins such as Teflon (registered trademark). These resin materials may be used alone, or may be formed using a resin sheet in which a thin layer made of a fluororesin is formed. The thickness of the resin sheet is preferably 0.5 to 5 mm, and more preferably 1 to 3 mm. The elastic modulus of the resin sheet is preferably in the range of 1.0 × 10 ⁴ kg / cm ² or more and 10 ⁶ kg / cm ² or less.

  FIG. 2 is a plan view of the box groove 11 provided with the contact member 12 as viewed from the opening 3 side. FIG. 3 is a cross-sectional view taken along the cutting plane line S1-S1 in FIG. The box groove portion 11 has a pair of rising portions 13 rising from the peripheral wall 4 and a bottom surface portion 14 connected to one end portion of each rising portion 13 on the peripheral wall 4 side. The abutting member 12 is provided in a groove portion (hereinafter sometimes referred to as “fixed groove portion”) 24 formed in the bottom surface portion 14 of the box body groove portion 11. In the present embodiment, the width dimension of the contact member 12 and the width dimension of the fixed groove portion 24 are formed substantially the same.

  Specifically, the contact member 12 is formed of a rectangular resin sheet having a long side and a short side. The abutting member 12 is fixed in a state where both end portions 15 in the long side direction are in contact with both end portions 16 in the longitudinal direction of the fixing groove 24 in a bent state. At this time, the contact member 12 is fixed in contact with both end portions 16 in the longitudinal direction of the fixed groove portion 24 by a restoring force of bending. The contact member 12 may be fixed to the fixing groove portion 24 by a fastening member such as a screw and a resin adhesive. By bending the abutting member 12 in the fixed groove portion 24, a distal end side portion (hereinafter sometimes referred to as a “leading end portion”) 17 that is a central portion in the longitudinal direction of the abutting member 12 extends from both end portions 15 into the inside of the box. It is formed in the arch shape which protrudes toward.

  The resin sheet used for the contact member 12 of the present embodiment is specifically formed of polyethylene terephthalate, but is not limited to polyethylene terephthalate, and is not particularly limited as long as it is a member that does not contaminate the plate-shaped object. It is not limited. The resin sheet is formed to have a longitudinal dimension of 70 mm, a width dimension of 10 mm, and a thickness dimension of 1 mm. Specifically, the fixed groove portion 24 is formed to have a dimension between both end portions 16 in the longitudinal direction of 60 mm. The resin sheet 27 is fixed to the fixed groove portion 24 with a bending amount, which is a distance from the surface portion 24 a continuous with the both end portions 16 of the fixed groove portion 24, to the tip end portion 17 of the resin sheet 27 being 2 cm.

  FIG. 4 is a cross-sectional view of the storage box 1 showing a state in which the plate-shaped storage object 18 is stored. A plurality of contact members 12 may be provided for each box groove 11. In this embodiment, the contact member 12 is a box groove 11 formed in the first peripheral wall 5 and the second peripheral wall 6. Two are provided for each. Specifically, it is provided at one end 19 on the opening 3 side of the box groove 11 and the other end 20.

  In the present embodiment, a stopper 22 is provided on the bottom wall 21 that closes the other of the peripheral walls 4 to prevent displacement of the plate-shaped storage object 18 in the insertion direction A while being disposed in the storage region D. The stopper 22 is formed by a member having flexibility and elasticity. Specifically, the stopper 22 is formed of a resin sheet. Specifically, the resin sheet is formed by being provided on the bottom wall 21 so as to protrude from the bottom wall 21 in an arch shape in a bent state.

  The plate-shaped object 18 of the present embodiment is a flat rectangular plate-shaped member having a long side and a short side. The plate-shaped object 18 is inserted and stored from the opening 3 of the storage box 1 so that both ends 36 in the long side direction follow the box groove 11 until one end 23 in the short side abuts against the stopper 22. It is stored in the space D. Specifically, the storage space D is a space surrounded by the contact member 12 and the stopper 22.

  The stored plate-shaped object 18 is elastically held between the contact members 12. A stopper 22 is interposed between the bottom wall 21 and the one end 23 in the short direction of the plate-shaped object 18, that is, the insertion direction A, and is held in the storage space D. Accordingly, the plate-shaped object 18 can be stored so as not to contact the box groove 11 and the bottom wall 21. Further, the stopper 22 is deformed so as to wrap around the one end portion 23 in the insertion direction A of the plate-shaped storage object 18 by its own weight. Thus, the plate-shaped object 18 can be reliably held so as not to be displaced in the thickness direction.

  FIG. 5A is a plan view seen from the side of the opening 3 showing the box groove 11 in an enlarged state where the plate-shaped object 18 is not held in the storage space D, and FIG. FIG. 3 is a plan view seen from the side of the opening 3 showing an enlarged view of the box groove 11 in a state in which the plate-shaped object 18 is stored in the storage space D. FIG. 6 is a cross-sectional view taken along the section line S2-S2 in FIG.

  Since the abutting member 12 is provided in an arch shape, when the plate-shaped object 18 is inserted into the box body 2, it is elastically deformed from the state shown in FIG. Is shrunk toward the bottom surface portion 37 of the box groove 11. Moreover, since the contact member 12 is formed of resin, the surface is formed smoothly. In a state where the plate-shaped object 18 is in contact with the abutting member 12 and the resin sheet 27 is degenerated, the resin sheet 27 has both ends in the long side direction of the plate-shaped object 18 as shown in FIG. Deform so as to wrap 36. As a result, displacement of the plate-shaped object 18 in the thickness direction can be prevented. Therefore, it is possible to prevent the plate-shaped object 18 from being displaced in the thickness direction and colliding with the box groove 11 or the like.

  Further, when the longitudinal end portions 36 of the plate-shaped storage object 18 abut on the abutting member 12, the abutting member 12 bends so that the distal end portion 17 is close to the fixed groove portion 24. At this time, the abutting member 12 is fixed in proportion to the amount of deflection, that is, the distance ΔX at which the distal end portion 17 approaches the fixed groove portion 24 because the long-side end portions 15 are fixed to the longitudinal direction both end portions 16 of the fixed groove portion 24. A restoring force F to be applied is applied to the plate-shaped storage object 18.

The restoring force F acts as a force for fixing the plate-shaped storage object 18 to the storage space D. Therefore, by providing the contact member 12 in the box groove portion 11, the plate-shaped object 18 comes into contact with the stopper 22 without contacting the box groove portion 11. The plate-shaped object 18 receives force from the contact member 12 in the thickness direction of the plate-shaped object 18 and the direction perpendicular to the thickness direction and the insertion direction A, and is fixed to the storage region D by this force. Is done. The distance ΔX that the tip 17 of the abutting member 12 made of a resin sheet approaches toward the fixed groove 24 by inserting the plate-shaped object 18 is 0.2 cm. A restoring force F is constantly applied to the plate-shaped object 18 by the deformation of the contact member 12. For example, in this embodiment, the restoring force is 880 g. The spring constant K of the contact member 12 is expressed by the formula (1).
K = F / ΔX (1)

  The spring constant K of the contact member 12 of the present embodiment is 0.4 kgf / mm. The spring constant K of the contact member 12 is preferably 0.1 kgf / mm or more and 1.0 kgf / mm or less.

As an example, a storage box 1 in which a contact member 12 is provided in a box groove 11 using resin sheets having different elastic coefficients is prepared, and the storage box 1 is lifted by 5 cm in the height direction by hand. An experiment was conducted to drop the release storage box 1. A glass plate was used as the plate-shaped object 18. The amount of displacement of the glass plate and the degree of damage were confirmed for each contact member 12 using resin sheets having different elastic coefficients. As a result, when the elastic modulus of the resin sheet 27 is less than 1.0 × 10 ⁴ kg / cm ² , the glass plate is displaced from the guiding means using the resin sheet 27 or a glass plate with a part missing is present. did. Further, when the elastic modulus of the resin sheet 27 exceeds 10 ⁶ kg / cm ² , there was no position shift between the contact member 12 and the glass plate, but the surface of the glass plate at the contact portion with the contact member was not generated. Scratch marks were observed.

Thus, if the contact member 12 is a plate-like member such as a resin sheet and the elastic coefficient is 1.0 × 10 ⁴ kg / cm ² or more and 10 ⁶ kg / cm ² or less, the storage box is removed. Even when a typical impact is received, it is possible to prevent the plate-shaped stored object from being displaced and to prevent a scratch mark or the like from being generated on the surface of the plate-shaped stored object. When the elastic coefficient of the contact member 12 is less than 1.0 × 10 ⁴ kg / cm ² , the plate-shaped storage object 18 is displaced from the contact member 12, so the plate-shaped storage object 18 and the box The body 2 may collide. Further, when the elastic coefficient of the contact member exceeds 10 ⁶ kg / cm ² , there is a possibility that an abrasion mark may be generated on the surface of the plate-shaped object 18. The contact member 12 has an elastic coefficient of 1.0 × 10 ⁴ kg / cm ² or more and 10 ⁶ kg / cm ² or less, so that even when the storage box receives an external impact, It is possible to prevent scratches and the like from being generated on the surface of the plate-shaped stored object without causing the stored object 18 to be displaced.

  According to the storage box 1 of the present embodiment, the storage box 1 has flexibility and elasticity, guides the plate-shaped storage object 18 to the predetermined storage area D, and in the storage area D the plate-shaped cover. And an abutting member 12 that elastically holds the stored item 18. Since the contact member 12 has flexibility, when the plate-shaped object 18 is inserted, it can be guided according to the size of the plate-shaped object 18. Therefore, when the plate-shaped object 18 collides with the contact member 12, the contact member 12 is deformed and the impact force can be reduced. Further, since the abutting member 12 has elasticity, the contact member 12 is deformed in accordance with the plate-shaped object 18 so that it can be guided without applying a large external force to the plate-shaped object 18. it can. Thereby, it is possible to prevent the plate-shaped object 18 from being damaged by an external force applied when the plate-shaped object 18 is inserted into the storage box 1.

  In addition, since the contact member 12 elastically holds the plate-shaped object 18, the contact member 12 absorbs the impact force even when the storage box 1 receives an impact force. Thereby, it is possible to prevent the impact force from acting on the plate-shaped storage object 18 and to prevent the plate-shaped storage object 18 from being damaged.

  According to the storage box 1 of the present embodiment, the contact member 12 is elastically deformed, and the distal end portion 17 can be retracted. Thereby, when inserting the plate-shaped storage object 18, it is possible to realize a guide according to, for example, the width dimension of the plate-shaped storage object 18. Moreover, the surface of the front-end | tip part 17 is formed smoothly. Accordingly, when the plate-shaped object 18 is inserted into the storage box 1, the frictional force generated between the plate-shaped object 18 and the contact surface of the contact member 12 can be reduced. Therefore, since the external force received by the plate-shaped storage object 18 when inserted into the storage box 1 can be reduced, the plate-shaped storage object 18 can be prevented from being damaged.

  According to the storage box 1 of the present embodiment, the contact member 12 elastically contacts the plate-shaped object 18 with the surface in the direction perpendicular to the thickness direction, so that at least the plate-shaped object 18 has a thickness. Hold it elastically in a direction perpendicular to the direction. Thereby, it is possible to prevent the plate-shaped object from being displaced in the storage box. Therefore, even when a plurality of plate-shaped objects are stored in the storage box, the plate-shaped objects can be prevented from colliding with each other, and the plate-shaped objects can collide with the storage box. Can be prevented.

  According to the storage box 1 of the present embodiment, the contact member 12 is formed by the resin sheet 27. Therefore, when the plate-shaped object 18 is stored while being guided by the contact member 12, it is possible to prevent the generation of dust due to rubbing between the resin sheet and the plate-shaped object. This can prevent the plate-shaped storage object 18 from being soiled.

  FIG. 7 is a plan view of a box groove 11 of a storage box according to another embodiment of the present invention as viewed from the opening 3 side.
