Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a semiconductor device such as an integrated circuit, a memory circuit or various irregularly shaped parts (for example, a connector, a switch, a transmitter), various electronic equipments or a relatively small precision machine assembly for precision machine assembly. The present invention relates to a chain type container for transporting precision parts, which is suitable for holding individual parts (collectively referred to as “IC chips”) individually and carrying them into an automatic assembly machine or the like.

2. Description of the Related Art In recent years, most of the main circuit components have tended to be formed into chips in order to improve the operational reliability and assembling efficiency of electronic equipment. Therefore, in order to supply IC chips to various intermediate processing lines, final assembly lines, and the like, a relatively large transport container having chip receiving recesses arranged in a plurality of rows and columns is used. In such a large container, individual transfer of chips to the processing or assembly line is performed by a robot hand or the like which is juxtaposed near one side edge of the transfer line, but the other side edge of the transfer line is used. When removing the IC chip at a location close to the robot from the container, the robot hand must reciprocate a long distance. This not only has a negative effect on efficiency because it increases the waiting time on the processing line side, but also requires the gripping position to be changed every time, and if there is not enough gripping, chip breakage or confusion in the processing line may occur. There is. In order to avoid such adverse effects, the position of the robot hand must be controlled with high precision, and the cost for control increases.
