Conventional technologyGlass substrates for liquid crystal displays, glass substrates for plasma displays,
In the manufacturing process of various substrates such as ceramic substrates for hybrid ICs and glass substrates for thermal heads, in order to process, process, clean, transport, and store the substrates, each substrate is placed in and out of cassettes so that they do not come into contact with each other. This is necessary. As a substrate cassette for this purpose, a cassette is used in which a pair of opposing side surfaces of a frame body are formed with grooved side plates so that substrates can be inserted into and stored in the corresponding grooves of both side plates. .. Examples of materials used for the cassette include glass fiber-filled polyphenylene sulfide and perfluoroalkoxy-substituted polytetrafluoroethylene.
In addition, it has also been proposed to use polyether ether ketone (Japanese Patent Laid-Open No. 62-247323,
(Refer to Japanese Patent Application Laid-Open No. 62-276849). There are various shapes and designs of grooved side plates.
All of them basically have a shape in which a large number of rib-like shelf pieces protrude from the side plate base. The gaps between adjacent rib-shaped shelf pieces become grooves, and substrates are moved in and out of these grooves. Figure 14 is. FIG. 2 is a perspective view showing an example of a typical overall shape of a substrate cassette. (1) is a frame, (11) is a bottom frame, (l2) is a ceiling frame, and (l3) is a receiving frame as a stopper for receiving a board. (2). (2) is a grooved side plate that constitutes a pair of opposing sides. A substrate cassette is normally used with the opening side facing sideways when loading and unloading the substrate, and with the opening side facing upward when transporting the substrate, but in this specification, the substrate cassette As a general rule, it is assumed that the device is used with the opening side facing sideways, and the view seen from the opening side will be defined as the front view. Regarding the grooved side plate, the front view is defined as the view from inside the cassette. In Fig. 14, a pair of opposing side surfaces are each formed by three grooved side plates (2), but a pair of opposing side surfaces are each formed by one grooved side plate (2). Alternatively, a pair of opposing sides may be formed by two or four grooved side plates (2). Boards can be moved in and out of the cassette with the above structure automatically by means such as running a conveyor belt lifted up from the gap in the bottom frame (1l), operating the shuttle 7-me from the opening side, or ejecting it with a pusher from the rear side. This is done manually, but there are also cases where workers do it by hand. Fig. 15 is a side view of a conventional grooved side plate (2);
The figure is a front view of the same. (21) is the back meat part, and (22) is the rib-like shelf piece projecting from the back meat part (21). (B) indicated by the two-dot chain line in Fig. 15 is the substrate. The rib-shaped shelf piece (22) has a grooved side plate (
2). It should be sufficient to provide it so as to protrude from the back meat part (21) only on the opposite side of the back meat part (21).
) If the rib-shaped shelf piece (22) is made to protrude only in one direction, there is a risk of distortion or deformation during molding or use under high temperature conditions. Therefore, in order to maintain balance, the present applicant has devised a device in which rib-shaped shelf pieces (22) are extended in both directions from the back meat part (21) as shown in FIG. 15. Problems to be Solved by the Invention However, in the conventional substrate cassette, the grooved side plate (2). When the board (B) is put in and taken out or stored in the groove of (2), the board (B) is placed on the shelf surface of the rib-shaped shelf piece (22).
In order to receive the edge of the board (B), the shelf surface is scraped off due to friction with the edge of the board (B), producing cutting chips, which sometimes adhere to the board (B) and have an adverse effect.
Also, during handling, the adjacent rib-shaped shelf pieces (22),
(22), that is, at the groove, the 2-7 ji of the board (B) may come into contact with the back wall part (21), so cutting waste may also be generated in this part. In order to prevent the shelf surface of the rib-shaped shelf piece (22) from being scraped off by the edge of the board (B), an idea has been taken to process the edge of the board (B) into a real shape with a chamfered surface. Applying such processing to the entire substrate (B) would significantly increase manufacturing costs, and could not generally be adopted. Moreover, even with such a device, there is a limit in that the edge of the board (B) cannot be sufficiently prevented from being scraped due to contact with the back wall part (21). In view of this situation, the present invention was made with the aim of solving the problems listed in L at once by improving the grooved side plate (2) itself. Means for Solving the Problems In the substrate cassette of the present invention, a pair of opposing side surfaces of a frame body (1) are formed with grooved side plates (2). (2), and these opposing grooved side plates (2). In the cassette in which the substrate (B) can be inserted into and stored between the corresponding grooves of (2), the shape of the grooved side plate (2) is adjusted so that the back wall portion (2)
1) has a shape in which a large number of rib-like shelf pieces (22) protrude from both sides, and the shelf face or free end of the shelf piece (22X) that protrudes toward the inside of the cassette among the shelf pieces (22). A protrusion (23) is formed, and a substrate (B) is attached to the protrusion (23).
) is characterized by a structure in which the plate surfaces of the grooved side plate (2) are in contact with each other. In this case, it is preferable to further adopt one of the following measures. The shelf piece (22) is attached to the meat part (21).
A protrusion (20) extending perpendicularly to the shelf surface direction of The back wall portion (21) has a tapered or rounded shape in which the center or a portion near the center is a thicker wall portion (25) than other portions when viewed in cross section in the direction of the shelf surface of the shelf piece (22X). Form into a shape. ■ Connect the back part (21) of the grooved side plate (2) to the adjacent shelf piece (22X).
.. (22X) to form an inclined shape. The present invention will be explained in detail below. A cassette consists of a frame (1) made up of frames. The frame (1) is composed of a bottom frame (11), a ceiling frame (12), and a receiving frame (13) as a stopper for receiving a board. The receiving frame (13) is often called the "receiving rod". A pair of opposing side surfaces of the frame (1) are formed by grooved side plates (2), (2). These grooved side plates (2
) and (2), the substrate (B) will be inserted into and removed from or accommodated in the corresponding grooves. One grooved side plate on each side (2)
It is also possible to form the cassette with a mold, but in this case, the large grooved side plate (2) is molded, so the mold becomes large, distortion is likely to occur during molding, and the weight of the cassette is large. becomes. Furthermore, when inserting the board (B) by hand, there is a disadvantage that it is difficult to insert the board (B) because it is likely to cause blurring, unlike when inserting the board automatically. Therefore, it is advantageous to install a plurality of (for example, 2 to 5) grooved side plates (2) on each side at intervals. The grooved side plate (2) used has a shape in which a predetermined number of rib-shaped shelf pieces (22) protrude in both directions from the back wall part (21). This is because if the shelf piece (22) is made to protrude only in one direction from the back wall part (21), there is a risk of distortion and deformation during molding or use under high temperature conditions. Each shelf piece (22) may be provided undivided over the entire width of one grooved side plate (2), or may be provided separately.

こともできる。In the present invention, a protrusion (23) is formed on the shelf surface or free end of the shelf piece (22X) that protrudes toward the inside of the cassette among the rib-shaped shelf pieces (22), and the protrusion (23) The board is configured so that the surface part (not the edge part) of the board (B) comes into contact with the board (B). The shape of the protrusion (23) may be a circular rod, a triangular rod, a cone, a hemisphere, a continuous hemisphere, or the like. Figures 7 to 10 are partial views showing examples of the grooved side plate (2), in which (A) is a longitudinal cross-sectional view and (B) is a cross-sectional view. FIG. 7 shows the protrusion (23) in the shape of a circular rod,
Figure 8 shows the protrusion (23) in a triangular rod shape, Figure 9 shows the protrusion (23) in a hemispherical shape, and Figure 10 shows the protrusion (23) in the shape of a hemisphere.
The figure shows the case where it is formed into a conical shape. The shelf piece (22Y) on the outside of the cassette may have a protrusion (23) in the same way as the shelf piece (22X) on the inside of the cassette, but since the mold becomes more complicated, usually the protrusion is (23) is formed into a shape that does not include. The protrusions (23) do not need to be provided on all the shelf pieces (22X), but should be provided in at least two separate locations (per one side of the cassette) in contact with both the front and back surfaces of the inserted board (B). That's fine. In the present invention, it is further desirable to provide the back wall portion (21) of the grooved side plate (2) with a protrusion (24) extending perpendicularly to the shelf surface direction of the shelf piece (22X). The protrusion (24) may be made of the same material as the grooved side plate (2), or may be made of a different material. If it is made of a different material, a material with sliding properties, abrasion resistance, or heat resistance, such as fluororesin, fluororubber, silicone rubber, ultra-high molecular weight polyethylene, etc., is used. The protrusions (24) may be formed at the same time as the grooved side plate (2) is formed, or may be attached after the grooved side plate (2) is formed. Place the back part (21) of the grooved side plate (2) on the shelf piece (22X).
When viewed cross-sectionally in the direction of the shelf surface, it can be formed into a tapered or rounded shape in which the outside becomes thinner only in certain areas on both ends, and this makes it easier to insert and remove the board (B). .. (For example, see Fig. 4) In addition, instead of providing the protrusion (20) on the back wall portion (21) described above, the back wall portion (21) of the grooved side plate (2) can be attached to the shelf piece (22X). It is also preferable to form it into a tapered or rounded shape in which the central or central portion is thicker than the other portions (25) in a cross-sectional view taken in the direction of the shelf surface. (Fig. 11 and (See Figure 12) Alternatively, the dorsal flesh (21) mentioned above may have a protrusion (24).
), the back wall portion (21) of the grooved side plate (2) is attached to the adjacent shelf piece (22X). It is also possible to form an inclined shape between (22X). (13th
(See figure) In addition, at least the shelf piece (22X) that protrudes toward the inside of the cassette among the shelf pieces (22) is tapered or rounded so that it becomes narrower and thinner toward the free end than the proximal end. Once formed, the insertion operation of the board (B) becomes easier. Two types of fastening holes (31) for attachment to the frame (1) are provided on the grooved side plate (2). (32) are provided in directions perpendicular to each other, the strength of the assembled cassette is significantly improved compared to when the grooved side plates (2) are simply attached to the frame (1) from the same direction. The resin constituting the frame body (1) and the grooved side plate (2) is a melt-formable resin that has the necessary strength, heat resistance, solvent resistance, chuic acid/alkali resistance, etc. depending on the purpose of use. For example, polyimide, polyetherimide, polyamideimide, polyetheretherketone, polyphenylene sulfide, perfluoroalkoxy-substituted polytetrafluoroethylene, polyarylate, polysulfone, polyallylsulfone, polyethersulfone, modified polyphenylene oxide, polyether Amide, Sakae lipropylene, etc., or these with glass m fiber,
Fiber-reinforced thermoplastic resins containing carbon fibers, aramid fibers, ceramic fibers, metal fibers, etc. are used.
As the melt molding method, injection molding method, extrusion molding method, transfer molding method, etc. are adopted. During melt molding, fillers, stabilizers, lubricants, and other additives may also be added.

In a cross-sectional view taken in the direction of the shelf surface, only 1/8 of the area on each end side is tapered so that the outside becomes thinner. (Refer to Figure 4) Of the shelf pieces (22X) on the inside of the cassette, which are divided into three parts and provided across the width of one grooved side plate (2), the left and right shelf pieces become closer to each other toward the free end. It is tapered to be narrower and thinner than the end side, and the free end is formed into a circular rod-shaped protrusion (23) that extends from the shelf surface. It's designed to be exciting. This protrusion (
23) comes into contact with the plate surface of the substrate (B). The shape of the protrusion (23) can also be a triangular rod shape as shown in FIG. 8, a hemispherical shape as shown in FIG. 9, or a conical shape as shown in FIG. 10. On the other hand, among the shelf pieces (22X) on the inside of the cassette, the central shelf piece is tapered so that it becomes narrower and thinner toward the roadside than the base end side. The shelf pieces (22Y) on the outside of the container, which are divided into three parts across the entire width of one grooved side plate (2), become narrower and thinner toward the free end than the proximal end. It is formed into a tapered shape. (24) is a protrusion, which is provided on the back wall (21) of the grooved side plate (2) in a direction perpendicular to the shelf surface direction of the shelf piece (22X). Note that this protrusion (24) is integrally formed by inserting it into a mold during injection molding of the grooved side plate (2). Projection (
As the material of 24), a material having sliding properties, wear resistance, or heat resistance (for example, fluororubber) is used.
(However, the protrusions (20) may be formed of the same material as the grooved side plate (2), or may be manufactured separately and installed later.) The cassette with the above structure is attached to the substrate ( When used as a case 7 for storing a glass substrate for a liquid crystal display as an example of B), the generation of cutting debris was reduced to the extent that it can be said that there was no generation.Example 2 Figures 11 and 12 show the grooves.
