In addition, the same reference numerals are given to those having the same functions as the conventional ones, and the description thereof will be omitted.

As shown in FIG. 1, reference numeral 11 denotes a transport tray for transporting the liquid crystal panel 1 having a rectangular main surface, which regulates the positions where the liquid crystal panel 1 comes into contact with the side surfaces of the three corners 3 respectively. One corner regulating portion 12, one side regulating portion 13 that contacts one side surface of a portion near the remaining corners and regulates the position of the rectangular plate-like member, and two receivers that receive and hold the liquid crystal panel 1 from the back side. The position of the liquid crystal panel 1 is restricted by the corner restriction part 12 and the side surface restriction part 13. The receiving portion 14 is arranged so as to receive a portion closer to the outer periphery than the effective display area A of the liquid crystal panel 1 in plan view (see FIG. 7).

As shown in FIGS. 12 to 14, the liquid crystal panel 1 is used as a liquid crystal panel 3 with a TCP in which a tape carrier package (TCP) 2 is mounted, or a print obtained by further mounting a printed circuit board 4. It may be used as the liquid crystal panel 5 with a substrate. Then, in order to cope with this, the corner regulating portion 12 and the side surface regulating portion 13 are arranged at locations other than the TCP 2 and the printed circuit board 4.

FIGS. 5 to 7 show the transport tray 11 provided with six storage recesses 11a for storing the liquid crystal panel 3 and the like. As shown in FIGS. Spacers 15 are provided on the back surface at the corners and the central portion where the storage recesses 11a are not provided, and are brought into contact with the lower transport trays 11 when the plurality of transport trays 11 are stacked vertically. Even when the transport trays 11 are vertically stacked, the liquid crystal panel 1 and the transport trays 11 above the liquid crystal panel 1 do not come into contact with each other and are kept separated from each other. In addition, FIG.
In FIG. 6, reference numeral 16 denotes a concave rib for preventing warpage during molding, which prevents the transport tray 11 from warping due to the weight of the liquid crystal panel 1 even when the liquid crystal panel 1 is placed on the transport tray 11. Has been done.

The carrier tray 11 is made of, for example, a conductive material obtained by kneading carbon with polystyrene or polyvinyl chloride. Although the carrier tray 11 is manufactured by molding with a mold, for example, a shape corresponding to the spacer 15 is formed in the mold and the spacer 15 is molded at the time of molding.
It is also possible to build in at the same time.

With the above construction, as shown in FIG. 2, the liquid crystal panel 3 is formed by the corner regulating portion 12 and the side regulating portion 13.
Position can be securely controlled and held, and
Since the corner restricting portion 12 and the side restricting portion 13 are disposed at locations other than the TCP 2 and the printed circuit board 4, as shown in FIGS. 3 and 4, the liquid crystal panel 3 with the TCP and the liquid crystal with the printed circuit board are mounted on the transport tray 11. Even when the panel 5 is accommodated, the corner control portion 12 and the side surface control portion 13 do not interfere with the TCP 2 and the printed circuit board 4, and the transport tray 11 having the same shape can transport the panel 5 without any trouble.

Further, since the receiving portion 14 receives and holds the area other than the effective display area A of the liquid crystal panel 1, the polarizing plate of the liquid crystal panel 14 is not damaged. By the way, since there is no spacer in the conventional carrying tray, when the carrying trays are overlapped with each other, as shown in FIG. 14, there is no space on the upper surface of the liquid crystal panel 1 and the polarizing plate is damaged. However, since the spacer 15 is provided in the transport tray 11 of the present invention, as shown in FIG. 8, even when the transport trays 11 are overlapped with each other, the space between the liquid crystal panel 1 and the transport tray 11 located above the liquid crystal panel 1 is increased. Therefore, a suitable space is secured, a load is prevented from being applied to the surface of the liquid crystal panel 1, and the liquid crystal panel 1 is prevented from being damaged.

Further, since the carrier tray 11 has conductivity, the terminals of the liquid crystal panel 11 are not damaged by static electricity or the like. As a result, the transport tray 11
When carrying by the above, not only the liquid crystal panel 11 alone but also the liquid crystal panel 3 with TCP and the liquid crystal panel 5 with the printed circuit board can be carried without any trouble, and the liquid crystal panel 11
Since the physical damage and the electrical damage are prevented, it is possible to prevent the defective liquid crystal panel 11 from being generated.

In the above embodiment, the case where the corner regulating portions 12 are provided at three locations for one liquid crystal panel 1 installation location on the carrying tray 11 has been described, but the corner regulating portions 12 are provided only at two locations. However, it is possible to reliably support the liquid crystal panel 1 and the like. Further, the case where the liquid crystal panel 1 is used as the rectangular plate-shaped body has been described, but this transport tray 11 is used for transporting other rectangular plate-shaped bodies having a rectangular main surface.
It is also possible to apply. Further, in the above embodiment, a part of the corner regulating portion 12 is bent inward,
Although the structure in which the TCP 2 can be guided by the bent portion 12a is shown, a structure without the bent portion 12a may be used. Further, in the above-described embodiment, the carrying tray 11 having the six storage recesses 11a for storing the liquid crystal panel 3 is shown, but it goes without saying that the present invention is not limited to this. Further, in the above embodiment, the receiving portion 1
Although the case where the liquid crystal panel 1 is received and held from the back side by 4 is shown, it is also possible to hold the liquid crystal panel 1 in the inverted position, that is, while receiving the main surface side of the liquid crystal panel 1 by the receiving portion 14. .

[0025]

As described above, according to the present invention,

A side regulating portion that regulates the position of the rectangular body, and a receiving portion that receives and holds the rectangular plate body from the back surface side or the main surface side, and an effective display area of the rectangular plate body when the receiving portion is viewed in plan. By arranging so as to receive a portion other than the specific area, it is possible to prevent a portion such as a polarizing plate in the specific area from being damaged.

Further, by disposing the corner restricting portion and the side restricting portion at a position other than the mounting portion of the mounting object, the carrier tray interferes with the mounting object such as the tape carrier package or the printed circuit board. Therefore, not only the liquid crystal panel, but also the rectangular plate-shaped body to which the attachment such as the liquid crystal panel with TCP or the liquid crystal panel with the printed circuit board is attached can be transported in the same transport tray without any trouble.

Further, since the spacers are provided, even when the transport trays on which the rectangular plate members are placed are vertically stacked, the upper or lower transport trays do not come into contact with the loaded rectangular plate members. This also prevents the portion of the specific region from being damaged.

Further, by making the carrying tray conductive, it is possible to prevent electrical damage to a specific area such as a liquid crystal panel due to static electricity. As a result, not only a rectangular plate-like body such as a liquid crystal panel but also a rectangular plate-like body with a TCP-attached liquid crystal panel or a printed board-attached liquid crystal panel attached thereto can be conveyed without any hindrance when it is conveyed by the conveyance tray. In addition to the improvement, physical damage and electrical damage to the rectangular plate-shaped body such as a liquid crystal panel can be prevented, so that it is possible to prevent the occurrence of defective products and the reliability of the rectangular plate-shaped body such as a liquid crystal panel as a product. improves.
