Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of use> The present invention relates to a packaging case for storing and holding a large number of liquid crystal display elements with lead pins, and more specifically, a packaging for storing and holding liquid crystal display elements with bent lead pins. Regarding the case.

<Prior Art> As a conventional packaging case for a liquid crystal display element with lead pins, as shown in FIG. 3 (a), the main body side of the liquid crystal display element 2 and the lead pin 3 side are in a mountain shape so that they are in contact with the adjacent inclined surfaces. There is a tray 1'formed on the tray 1'holding the liquid crystal display elements 2 and stacking them in a plurality of stages as shown in FIG. 3 (b). As shown in FIG. 4, one side of the tray 1 ″ is formed to have at least the width 1 of the liquid crystal display element 2 and the length d of the bent tip end portion of the lead pin 3 so that the liquid crystal display element 2 is continuous. I arranged them side by side.

<Problems to be solved by the invention> In the conventional packaging case described above, when the former is formed by stacking the lead pins, the tips of the lead pins may be bent when stacked, and the latter has a deformed mountain shape with one side long. Therefore, there is a problem that the strength of the packaging case itself is lowered, and since the packaging cases are arranged in a substantially flat plane, the number of storage per unit area is limited.

The present invention is intended to solve the above conventional problems.

<Means for Solving the Problem> In the present invention, the above conventional problems are solved by forming the top of the tray into a substantially M-shape having two continuous peaks corresponding to the formed lead pins.

<Operation> The substantially M-shaped bent portion of the tray protects the bent lead pins from the periphery by a gap formed when the liquid crystal display elements are placed and stacked, and prevents the lead pins from bending. To work.

<Example> Hereinafter, the present invention will be described in detail based on an example shown in the drawings.

The packing case of the present invention is formed by stacking a plurality of transparent synthetic resin trays 1 and 1 as shown in the sectional view of the main part of FIG. 1, and each tray 1 is formed by bending portions 1a, 1c and 1b. Two mountains
It is bent and formed into a continuous M-shaped cross section. A plurality of such bent portions having a substantially M-shaped cross section are provided at predetermined intervals as shown in the top view of FIG.

Further, in the figure, reference numeral 2 denotes a liquid crystal display element having a polarizing plate 2a attached to the upper surface thereof, and a lead pin 3 is formed so as to project from one side thereof. The leading end 3b of the lead pin 3 is bent outward by bending (forming).

That is, the lead pin 3 has a base end portion 3a that is bent and extends at a right angle from the main body of the liquid crystal display element 2, and a tip end portion 3b that is bent and extends from the base end portion 3a.

The bent portion 1a of the tray 1 corresponds to the bent portion between the main body of the liquid crystal display element 2 and the base end portion 3a of the lead pin 3, and the bent portion 1c corresponds to the base end portion 3a and the tip end portion 3b of the lead pin 3. Corresponding to the bent portion, the bent portion 1b is formed so as to bend near the terminal end of the tip end portion 3b of the lead pin 3 and continue to the adjacent storage portion.

As shown in FIG. 1, the liquid crystal display element 2 is placed on the tray 1 so that the bent portion at a right angle on which the lead pin 3 is projected is located on the bent portion 1a of the tray 1,
Similarly, after the liquid crystal display elements are arranged at other predetermined positions of the tray 1, the same tray 1 is stacked on the liquid crystal display element 2. Here, the liquid crystal display element 2
Since the main body side to which the polarizing plate 2a is attached is thick, a gap is created in the bent portion of the substantially M-shape when the trays 1 are stacked, and the lead pin 3 is housed and held in the gap. Therefore, even if they are stacked, the lead pin 3
No external force acts on the lead pin 3 and the formed lead pin 3 is reliably prevented from being deformed.

It is assumed that the tray 1 is formed such that its end portion 1d is gradually expanded upward so that it can be stacked.

As described above, in the liquid crystal display element packaging case of the present invention, the liquid crystal display elements are held between the upper and lower trays, and the liquid crystal display elements are similarly arranged on the stacked trays and sequentially stacked to obtain a large number of liquid crystal display elements. The element is packaged with its lead pin prevented from bending.

In this embodiment, the end portion of the tray is formed in an upper widened shape in order to protect the surface of the liquid crystal display element, and the tray is held also at the end portion. Instead, the trays may be simply stacked on the liquid crystal display element.

<Effect of the invention> As described above, in the packaging case of the liquid crystal display device of the present invention,
Since bending of the formed lead pins can be prevented and a large number of liquid crystal display elements can be stacked, the number of packages is increased and the lead pin breakage accident can be reliably prevented.
