1353951 * Ο) 1 九、發明說明 【發明所屬之技術領域】 本發明是一次載置1張薄板狀物品而執行搬運的托盤 。特別是可將大量的托盤堆疊於較小的空間並加以保管的 薄形物搬運用托盤。 【先前技術】 Φ 舉例來說，在薄形顯示裝置的製造工程等中，需要搬 運以玻璃基板作爲代表之薄板狀物品的技術。薄板狀物品 容易發生扭曲或彎折之類的變形，在搬運中因爲變形的原 因與周圍形成接觸而恐有於表面形成傷痕或破損之虞。因 % 此在搬運時，爲了不使薄板狀物品產生變形而採用可載置 的專用容器。 藉由將薄板狀物品一次1張載置於個別的容器後搬運 的方式，可防止搬運中物品的變形。但是上述型態的搬運 • 卻有著：在搬運途中暫時保管時，將佔用大量保管空間的 問題。此外，即使在欲集中於其他場所而執行移送的場合 中，也具有處理上繁瑣的問題。 因此，設計出一種：可個別載置薄板狀物品，且當暫 時保管或移送至其他場所時容器之間可堆疊的容器。雖是 如此，上述的容器卻發生：容器內蓄積灰塵、或堆疊時本 身產生的灰麈而污染所載置之物品的問題。此外，當堆疊 後之場合中全體的重量變重，也有著保管或運搬不便的問 題。 -5- (2) 1353951 爲了克服上述的問題點來執行薄板狀物品的搬運，乃 設計出可暫時收容複數張物品的卡匣。但是，在採用上述 卡匣來執行裝置間之搬運的場合中，在送入物品之各裝置 的入口，需要將薄板狀物品從卡匣取出後送入的專用送入 口埠。 薄形顯示裝置等，多數是於無麈室内所製造，而需要 無塵室内的搬運。爲了將玻璃基板送入無塵室内的各製造 Φ 裝置，需要灰塵的產生極低，且可無人操作之對應無塵室 的送入口埠。上述的送入口埠價格極爲昂貴，將導致搬運 系統的導入成本大增。 此外，近年來薄形顯示裝置急速地朝大型化邁進，表 示裝置所使用的大型玻璃基板的重量，1張形成數十公斤 。甚至，由於收容大型玻璃基板的卡匣也被要求相當的強 度，因此卡匣本身的重量也變大。通常，搬運是採用可收 容20張~40張玻璃基板而執行暫時搬運的箱狀卡匣，有時 • 已收容玻璃基板之卡匣的總重量會超過1噸。 用來送入大型化而變重之玻璃基板的口埠，只會變的 更昂貴，爲了在工程與工程之間搬運總重量爲1噸左右的 卡匣將需要吊車。由於需要上述的設備，在採用卡匣的搬 運系統中，形成系統的導入成本將隨著所搬運之物品的大 型化而大增的問題。 此外，利用人力來搬運1噸左右的卡匣是極爲困難的 事，故當送入口埠或吊車因爲調整或修理而停止運轉時， 玻璃基板的搬運有可能被迫中斷。因此，在傳統的搬運系 -6 - 1353951 ⑶ 統中，將因爲送入口埠或吊車的停止運轉而導致薄形顯示 裝置的製造工程停止，恐有招致製造工程全體的運轉率下 降之虞。 【發明內容】 [發明欲解決之課題] 本發明是有鑒於上述傳統技術之問題點所硏發的發明 ，本發明的課題是提供一種：是可一次1張地載置、搬運 薄板狀物品，並在複數張堆疊的狀態下加以保管的薄形物 搬運用托盤，可在較小的空間堆疊大量的托盤，藉由在堆 疊之際不會產生灰塵的方式而不會污染物品，不僅如此， 更是已形成輕量化的薄形物搬運用托盤。 [解決課題之手段] 申請專利範圍第1項的發明，是可在複數堆疊的狀態 下保管的薄形物搬運用托盤。本發明的薄形物搬運用托盤 ，其特徵爲：藉由將柵桿架設於外框間而形成工件載置部 ，並在外框設置可供其他托盤從上方進入的收容部。 申請專利範圍第2項的發明，是薄形物搬運用托盤， 其特徵爲：外框與上下托盤之間的接觸部，是由灰塵之發 生較其他部分更少的樹脂塊所構成，且收容部不會與上下 的托盤接觸。 申請專利範圍第3項的發明，是薄形物搬運用托盤， 其特徵爲：可供其他托盤從上方進入的收容部，是由朝上 (4) 1353951 方擴張的傾斜面所構成。 [發明的效果] 根據本發明可提供一種：由於可縮小堆疊 距，故能以較小的空間保管大量托盤的薄形物 。此外，可輕易地獲得外框所需的強度。 根據本發明可提供一種：可重視強度來選 料，並可防止工件污染的薄形物搬運用托盤。 根據本發明，可輕易地形成可供其他托盤 的收容部。 【實施方式】 以下，列舉用來實施本發明的最佳形態。（ 薄形物搬運用托盤，是在利用4支板狀構件接召 形所構成的外框之間，藉由架設複數個柵桿的方 • 薄板狀物品的載置部。（形態2 )略成長方形的 有外側平坦部、及設於較與外側平坦部更低之位 平坦部，並在外側平坦部與内側平坦部之間設有 傾斜部的長度，被設定成可確保維持外框2的ζρ 強度的長度。當所需的強度較大時傾斜部變長， 強度較小時則縮短傾斜部。（形態3 )爲了構成 複數個樹脂塊被安裝於外側平坦部的4邊全體。 高度，是形成與可安全地收容1張薄板狀物品的 相等。（形態4 )樹脂塊是採用：耐磨耗性高， 的上下間 運用托盤 外框的材 上方進入 形態1 ) 成略長方 式來形成 外框，具 置的内側 傾斜部。 面所需之 當所需的 接觸部， 樹脂塊的 收容高度 且由於具 -8- • (5) • (5)1353951 有絕佳機械強度而不易產生灰塵的樹脂UPE(超高分子 量（高密度）聚乙烯）。（形態5)在複數個薄形物搬運 用托盤堆疊於上下方向的場合中，由於被傾斜部所包圍的 部分，具有作爲可供其他拖盤從上方進入之收容部的功效 ，各在不改變預定之收容高度的下形成堆疊。（形態6) 樹脂塊的頂面，是位於較外框之外側平坦部的頂面更高的 位置，樹脂塊的底面，是位在較外側平坦部的底面更低的 位置。在堆疊複數個薄形物搬運用托盤的狀態下，樹脂塊 的高度形成上下堆疊的間距。（形態7)在樹脂塊的頂面 設有凸部，在樹脂塊的底面設有凹部。底面的凹部，具有 對應於頂面之凸部的形狀。藉由使堆疊於上下方向之薄形 物搬運用托盤的樹脂塊之凸部與凹部形成嵌合的方式，可 定位薄形物搬運用托盤而形成固定》 [實施例] 以下’參考圖面來詳細說明適用於本發明之薄形物搬 運用托盤（以下，簡稱爲托盤）的實施例。第1圖，是顯 示本發明薄形物搬運用托盤之一種實施例的構成的立體圖 〇 本實施例的薄形物搬運用托盤1具備：外框2;和複 數個柵桿4,該複數個柵桿4是架設於外框2的相對側邊 之間；及接合構件6，該接合構件6是傾斜地架設於外框 用構件之接合部附近形成鄰接的構件之間。 外框2是由2支長邊構件2a與2支短邊構件2b所構 -9- • (6) 1353951 * 成。本實施例之長邊構件2a與短邊構件2b是使用特定板 厚的SUS304’並利用板金加工而加工成相同的剖面形狀 〇 第2圖（a) ’是顯示長邊構件2a與短邊構件2b的 立體圖，第2圖（b)是顯示第2圖（a)中的A— A剖面 圖。此外，第3圖是顯示長邊構件2a與短邊構件2b之端 部付近的立體圖。長邊構件2a與短邊構件2b，可由第2 φ 圖（b )的剖面形狀而清楚得知，具備：外側平坦部i】； 及形成在較外側平坦部1 1更低位置的内側平坦部1 2，並 於外側平坦部1 1與内側平坦部1 2之間設有傾斜部1 3。傾 斜部13被賦予一種：當外框2形成時朝上方變寬之錐形 的角度。又，在外側平坦部11的外側設有凸緣14。 傾斜部13的高度，在長邊構件2a與短邊構件2b組 合成長方形之外框2的場合中，是被設定成：可維持外框 2平面之所需強度的高度。因此，傾斜部13的高度，有時 ® 是形成超過可安全收容1張薄板狀物品之所需收容高度的 高度。在外框2的形狀形成大型化的場合中，所需要的強 度則變大’爲了強化外框2，傾斜部1 3的高度變的更高。 在小型外框因而所需強度較小的場合中，可降低傾斜部1 3 〇 藉由接合長邊構件2a與短邊構件2b，而形成本實施 例的外框2。本實施例的外框2，其剖面剖面形狀如上所 述’是由：凸緣14;及略高於凸緣14的外側平坦部11;

Description of the Invention [Technical Field of the Invention] The present invention relates to a tray in which one sheet-like article is placed and transported. In particular, a thin material carrying tray in which a large number of trays can be stacked in a small space and stored. [Prior Art] Φ For example, in the manufacturing process of a thin display device, etc., it is necessary to transport a thin plate-shaped article represented by a glass substrate. Thin-plate-shaped articles are prone to deformation such as twisting or bending, and may cause flaws or breakage on the surface due to contact with the surroundings due to deformation during transportation. % This is a special container that can be placed in order to prevent deformation of the thin plate-shaped article during transportation. By placing the thin plate-like articles one by one in an individual container and transporting them, it is possible to prevent deformation of the articles during transportation. However, in the above-mentioned type of handling, there is a problem that a large amount of storage space is occupied when temporarily stored during transportation. Further, even in the case where the transfer is to be performed in another place, there is a problem that the processing is cumbersome. Therefore, a container which can be stacked between the containers when temporarily stored or transferred to other places is designed. In spite of this, the above-mentioned container occurs: the accumulation of dust in the container, or the ash generated by itself when stacked, which contaminates the contents of the article. In addition, when the weight is increased in the case of stacking, there is also a problem of inconvenience in storage or transportation. -5- (2) 1353951 In order to overcome the above problems, the handling of thin-plate-shaped articles is carried out, and a cassette that can temporarily accommodate a plurality of articles is designed. However, in the case where the above-described cassette is used to carry out the conveyance between the devices, the entrance of each device into which the article is fed requires a dedicated feed port that the thin plate-shaped article is taken out from the cassette and then fed. Most of the thin display devices and the like are manufactured in a flawless room, and are required to be transported in a clean room. In order to feed the glass substrate into each of the manufacturing Φ devices in the clean room, it is required that the generation of dust is extremely low, and the inlet port of the corresponding clean room can be unmanned. The above-mentioned delivery port is extremely expensive, which will lead to an increase in the cost of introducing the handling system. Further, in recent years, the thin display device has rapidly advanced toward the enlargement, indicating that the weight of the large-sized glass substrate used in the device is several tens of kilograms. Even since the cassette for accommodating a large glass substrate is required to have a considerable strength, the weight of the cassette itself is also increased. Usually, the handling is a box-shaped cassette that can be temporarily transported by taking 20 to 40 glass substrates. Sometimes, the total weight of the cassette that has received the glass substrate exceeds 1 ton. The port used to feed the large and heavy glass substrate will only become more expensive. In order to carry a cassette with a total weight of about 1 ton between engineering and engineering, a crane will be required. Since the above-described equipment is required, in the transportation system using the cassette, the introduction cost of the forming system will increase as the size of the articles to be transported increases. Further, it is extremely difficult to carry a cassette of about 1 ton by manpower. Therefore, when the delivery port or the crane is stopped due to adjustment or repair, the conveyance of the glass substrate may be interrupted. Therefore, in the conventional transport system -6 - 1353951 (3), the manufacturing process of the thin display device is stopped due to the stoppage of the inlet port or the crane, and the operation rate of the entire manufacturing process may be lowered. [Problem to be Solved by the Invention] The present invention has been made in view of the problems of the above-described conventional techniques, and an object of the present invention is to provide a sheet-like article that can be placed and transported one at a time. The thin material carrying tray which is stored in a plurality of stacked state can stack a large number of trays in a small space, and does not pollute the articles by stacking dust during the stacking, and not only, In addition, a lightweight tray for transporting thin objects has been formed. [Means for Solving the Problem] The invention of claim 1 is a thin-material conveyance tray that can be stored in a plurality of stacked states. In the thin article transporting tray of the present invention, the workpiece placing portion is formed by arranging the grid bar between the outer frames, and the outer frame is provided with an accommodating portion into which the other tray can be accessed from above. According to the invention of claim 2, the invention relates to a tray for transporting thin objects, characterized in that the contact portion between the outer frame and the upper and lower trays is composed of a resin block having less dust generation than other portions, and is accommodated. The department will not touch the upper and lower trays. According to the invention of claim 3, the tray for thin material conveyance is characterized in that the accommodating portion for allowing the other tray to enter from above is constituted by an inclined surface which is expanded upward (4) 1353951. [Effects of the Invention] According to the present invention, it is possible to provide a small amount of thin objects of a tray with a small space because the stacking distance can be reduced. In addition, the strength required for the outer frame can be easily obtained. According to the present invention, it is possible to provide a tray for transporting a thin article which can be selected with a high degree of strength and which can prevent contamination of a workpiece. According to the present invention, the accommodating portion for other trays can be easily formed. [Embodiment] Hereinafter, the best mode for carrying out the invention will be listed. (The thin-sheet conveyance tray is a mounting portion of a thin-plate-shaped article in which a plurality of grid bars are stacked between the outer frames formed by the call-up shapes of the four plate-shaped members. (Form 2) The rectangular flat portion has an outer flat portion and a flat portion that is provided at a lower position than the outer flat portion, and a length of the inclined portion is provided between the outer flat portion and the inner flat portion, and is set to ensure that the outer frame 2 is maintained. The length of the ζρ intensity. When the required strength is large, the inclined portion becomes long, and when the strength is small, the inclined portion is shortened. (Form 3) In order to form a plurality of resin blocks, the entire four sides of the outer flat portion are attached. It is formed to be equal to the one that can safely accommodate one sheet-shaped article. (Form 4) The resin block is used: high wear resistance, and the top and bottom of the material of the tray frame are used to enter the form 1) into a slightly longer way. The outer frame is formed with an inner inclined portion. The required contact area for the surface, the storage height of the resin block, and the resin UPE (Ultra High Molecular Weight (High Density) with -8- • (5) • (5) 1353951 which has excellent mechanical strength and is not easy to generate dust. ) Polyethylene). (Form 5) When a plurality of sheets for transporting thin objects are stacked in the vertical direction, the portion surrounded by the inclined portion has an effect of being able to accommodate the other trays from above, and does not change. A stack is formed under the predetermined accommodation height. (Form 6) The top surface of the resin block is located higher than the top surface of the flat portion on the outer side of the outer frame, and the bottom surface of the resin block is located lower than the bottom surface of the outer flat portion. In a state in which a plurality of sheets for transporting thin objects are stacked, the height of the resin blocks forms a pitch which is stacked on top of each other. (Form 7) A convex portion is provided on the top surface of the resin block, and a concave portion is provided on the bottom surface of the resin block. The concave portion of the bottom surface has a shape corresponding to the convex portion of the top surface. By fitting the convex portion of the resin block stacked on the thin object transport tray in the vertical direction to the concave portion, the thin object transport tray can be positioned and fixed. [Embodiment] Hereinafter, the reference plane is used. The embodiment of the thin-material conveyance tray (hereinafter, simply referred to as a tray) to which the present invention is applied will be described in detail. Fig. 1 is a perspective view showing a configuration of an embodiment of a thin article transporting tray of the present invention. The thin article transporting tray 1 of the present embodiment includes: an outer frame 2; and a plurality of grid bars 4, the plurality of The grid bar 4 is spanned between the opposite side edges of the outer frame 2, and the joint member 6 is disposed between the adjacent members in the vicinity of the joint portion of the outer frame member. The outer frame 2 is composed of two long side members 2a and two short side members 2b -9- • (6) 1353951 *. The long-side member 2a and the short-side member 2b of the present embodiment are processed into the same cross-sectional shape by sheet metal processing using SUS304' having a specific sheet thickness. FIG. 2(a) ' shows the long-side member 2a and the short-side member 2b is a perspective view, and Fig. 2(b) is a cross-sectional view taken along line A-A of Fig. 2(a). Further, Fig. 3 is a perspective view showing the vicinity of the end portions of the long side member 2a and the short side member 2b. The long side member 2a and the short side member 2b can be clearly seen from the cross-sectional shape of the second φ diagram (b), and include: an outer flat portion i]; and an inner flat portion formed at a lower position than the outer flat portion 1 1 1 2, an inclined portion 13 is provided between the outer flat portion 1 1 and the inner flat portion 1 2 . The inclined portion 13 is given an angle of a taper which becomes wider toward the upper side when the outer frame 2 is formed. Further, a flange 14 is provided on the outer side of the outer flat portion 11. When the long side member 2a and the short side member 2b are combined into the rectangular outer frame 2, the height of the inclined portion 13 is set to a height at which the required strength of the outer frame 2 plane can be maintained. Therefore, the height of the inclined portion 13 may be a height that exceeds the required accommodation height for safely accommodating one sheet-like article. When the shape of the outer frame 2 is increased in size, the required strength is increased. In order to strengthen the outer frame 2, the height of the inclined portion 13 is higher. In the case where the small outer frame is required to have a small strength, the inclined portion 1 3 can be lowered to join the long side member 2a and the short side member 2b, thereby forming the outer frame 2 of the present embodiment. The outer frame 2 of the present embodiment has a cross-sectional cross-sectional shape as described above by: a flange 14; and an outer flat portion 11 slightly higher than the flange 14; and an inclined portion connected to the outer flat portion 1 1 and forming a lower portion 1 3 and connection-10- 1353951 . (6) « Wear, and since it does not generate dust, it will not contaminate the transported sheet-like items. The resin block 8 is fixed to the outer frame 2 by rivets or screws. Figs. 5 and 6 are schematic views showing a state in which the resin block 8 is fixed to the long side member 2a by caulking. Fig. 5 is a cross-sectional view in the longitudinal direction of the long-side member 2a, and Fig. 6 is a side view showing the long-side member 2a. The resin block 8 is formed on the bottom surface of the support portion 23 by abutting on the bottom surface of the outer flat portion of the long side member 2a, and is formed by being fixed from the block mounting hole 15a to the upper portion of the convex portion 21 and the main body portion 20. . The resin block 8 fixed to the outer frame 2 has a top surface of the main body portion 20 which is formed to be higher than the outer flat portion 11 of the long side member 2a. Further, the bottom surface of the body portion 20 is formed to be lower than the bottom surface of the flange 14 provided on the outer flat portion 11. By stacking the thin matter transport trays 1 in the up and down direction in a plurality of layers by the above-described arrangement of the outer frame 2 and the resin block 8, the top and bottom surfaces of the body portion 20 of the resin blocks 8 of the respective trays are mutually To form a contact, the thin-sheet transport tray 1 is stacked with the height of the body portion 20 of the resin block 8 as a pitch. In the thin-sheet conveying tray 1 of the present embodiment, the resin block 8 and the outer frame 2 as the contact portions are formed separately and fixed by using different materials. In this way, the contact portion can be made of a material capable of suppressing dust generation, and the contact portion can be easily processed to form a contact portion. In addition, since the other portions of the outer frame 2 are hardly brought into contact with other thin matter transport trays 1 or equipment, etc., materials which are more important in strength other than dust suppression can be used, and the material of the outer frame 2 can be selected. The degree of freedom becomes greater. -12- ' (9) 1353951 Further explanation of the configuration of the outer frame 2. The long side member 2a and the short side member 2b' are joined by the l-shaped joint fixing fixture 1 shown in Fig. 7. The joint fixture 10 of the present embodiment is provided with three on each side of the L-shape, that is, six engagement holes 18 are provided. The relative position between the engaging holes 18 is the same as the relative positional relationship between the holes of the joining holes 16 of the long side member 2a and the short side member 2b. One of the joint fixtures 10 is overlapped with the φ end of the long side member 2a. A blind rivet is inserted so as to penetrate both the joint hole 16 of the long-side member 2a and the joint hole 18 of the joint fixture 10, and the long-side member 2a and the joint fixture 10 are rivet-joined. The other side of the joint fixture 10 is overlapped with the end of the short side member 2b. The blind rivet is driven in such a manner that both the joint hole 16 penetrating the short side member 2b and the joint hole 18 of the joint fixture 10 are engaged, and the short side member 2b and the joint fixture 10 are blindly rivet joined. The two long side members 2a and the two short side members 2b are formed by the four joint fixing members 10 to form a rivet rivet joint to form a substantially rectangular outer φ frame 2. The outer frame 2 formed by the blind rivet joining is provided with a space 19 at the upper portion of the joint portion between the long side member 2 and the short side member 2b (please refer to Fig. 1). By providing the space 19, dust does not remain in the joint portion', and the washing and drying of the outer frame 2 can be easily performed. In other words, by providing the space 19, dust does not accumulate in the joint portion of the outer frame 2, and the effect of preventing contamination of the thin plate-shaped article placed thereon can be obtained. In the thin article transporting tray of the present embodiment, a plurality of grid bars 4 are placed between the short-side members 2b facing the outer frame 2 to form a thin plate-like member-13-(10) 1353951 product. The grid bar 4 is made of SUS 304 having a specific thickness and processed by sheet metal processing to form a predetermined cross-sectional shape. An enlarged view of one end portion of the grid bar 4 is shown in Fig. 8. The grid bar 4 is formed with flat mounting portions 25 facing the outer frame 2 on both sides, and a raised portion 26 that protrudes upward is formed between the flat portions. At the end of the mounting portion 25, an outer frame mounting hole 27 for engaging the outer frame 2 is provided. A plurality of mounting pins 28 for supporting the thin plate-like articles are fixed to the raised portion 26. The φ mounting pin 28 is formed of U P E with high wear resistance. Even if a thin plate-shaped article is repeatedly mounted, dust due to abrasion does not occur, and the thin plate-shaped article is not contaminated. The rivet is driven in such a manner as to penetrate the outer frame mounting hole 27 of the grid 4 and the grid mounting hole 17 of the outer frame 2, so that the outer frame 2 and the grid 4 are rivet-bonded. Since the grid bar 4 is provided with the swelled portion 26, the grid bar 4 is joined to the outer frame 2 while the opening portions are held at both ends. Therefore, it is difficult to accumulate ash at the joint portion between the outer frame 2 and the grid bar 4, and it is possible to easily perform cleaning and drying of the portion of the grid bar 4 when the thin-sheet transport tray 1 is washed. Further, since the grid 4 is formed with the ridge portion 26, the beam strength can be improved as compared with the case of using the flat member. Therefore, the gate rod 4 can be made of a material having a small thickness, and the weight of the grid rod 4 can be achieved. The positioning member 6 is a long side member 2a and a short side which are mounted obliquely in the vicinity of the corner portion of the outer frame 2, in order to position the thin-plate-shaped article mounted on the thin-sheet-transporting tray 1 and to reinforce the corner portion of the outer frame 2. A perspective view of the joint member 6 between the members 2b is as shown in Fig. 9. The joint member 6 is provided with the same raised portion 26 as the gate rod 4, and is fixed to the raised portion for supporting the thin 14- • (13) 1353951 material carrying tray 1, and the height of the inclined portion 13 is changed to the entire height. The influence 'is only the height H2 of one of the accommodating portions 13b, and has a limited influence on the overall height. In this manner, the thin article transporting tray 1' of the present embodiment is provided with the inclined portion 13 of the tray 1 on the lower side, in such a manner that the inclined portion 13 of the other tray 1 to be stacked enters the accommodating portion 13b from above. Even in the case where the height of the inclined portion 13 has been changed, it is possible to stack with a smaller pitch than usual. φ As described above, when the thin-sheet transport tray 1 of the present embodiment is stacked in the vertical direction, 'only the resin block 8 is in contact between the upper and lower thin-material transport trays 1, and the outer frame 2 and the grid 4 is not in contact with the other thin matter transport tray 1 at all. Further, since the resin block 8 is formed of UP E, dust is not generated even if contact is formed. As a result, the thin-sheet conveying tray 1 of the present embodiment does not generate dust even when stacked, and does not contaminate the thin-plate-shaped article. In addition, the thin-sheet conveyance tray 1 of the present embodiment is configured to support the weight of the thin-sheet-transporting tray 1 stacked on the upper side by the resin block 8, and the load of the upper-side thin-material-transporting tray 1 is not Will act on the outer frame 2 . Therefore, the outer frame 2 only needs to have a strength capable of supporting its own weight and the weight of the thin plate-shaped article placed thereon, and the outer frame 2 is supported by the outer frame 2 to support the thin matter carrying tray 1 stacked thereon. The structure requires less strength. Therefore, the strength required for the outer frame 2 can be easily obtained, and the weight can be achieved. As described above, the outer frame 2 of the thin article conveying tray 1 of the present embodiment has a cross-sectional shape of: the flange 14 is slightly higher than the outer side of the flange 14 by -17-(14) 1353951 1) The inclined portion 13 connected to the outer flat portion 1 1 and the inner flat portion 12 connected to the lower side of the inclined portion 13 can be easily obtained by appropriately adjusting the height ' of the inclined portion 13 The strength required by Box 2. Further, the thin article conveying tray 1 of the present embodiment has a function as a portion of the inclined portion 13 as a housing portion 13b into which other trays can pass from above. Therefore, even in the case where the height of the inclined portion 13 becomes high, Φ when the plurality of trays 1 are actually stacked, the accommodation degree (Η 1 ) which is smaller than the height of the inclined portion 13 can be used as the upper and lower pitches' Keep a large number of pallets in a small space. In addition, the resin block 8 which is a contact portion of the upper and lower thin matter conveying tray 1 and the outer frame 2 are fixed by different materials, and the thin material conveying tray of the present embodiment is formed by different materials. 1 It is easy to process and form the contact portion 8 which is less likely to generate dust. The material of the outer frame 2 can be made of a material that emphasizes strength, and the degree of freedom of selection of the material of the outer frame 2 can be increased. Φ The above is a detailed description of specific examples of the invention in the examples, but the above description is only for the sake of example and the scope of the patent application is not limited thereto. The technology described in the scope of the patent application includes various modifications and changes of the specific examples described above. For example, in the embodiment, the joining method or the joining position of the long side member 2a and the short side member 2b of the outer frame 2; the joining method or the joining position of the outer frame 2 and the grid bar 4 can match the size of the thin plate-shaped article to be mounted. Or the weight is changed as appropriate. Further, the shape of the outer frame 2 or the shape or arrangement of the resin block 8 can be changed without departing from the effects. -18· (15) 1353951 [Brief Description of the Drawings] Fig. 1 is a perspective view for explaining the thin article conveying tray 1 of the embodiment.
