ＴＪｆ！認し選別仕分けを行っているのが現状である。Conventionally, automatic or semi-automatic testers have been used to detect electrical short circuits, disconnections, etc. of printed wiring boards. Conventionally, this operation involved an operator inserting the boards to be tested one by one into the tester, adding a press mechanism, and TJf! The current situation is that they are recognized, sorted and sorted.

板が大型な場合は適用できないという問題点があった。Conventionally, automatic conveyance devices include devices that utilize a moving endless belt to automatically supply a substrate to be inspected to an inspection device for inspection. This is because the inspection jig is fixed at the top of the inspection device, and the moving board to be inspected is pushed up from the bottom, but it is difficult to align the board when setting it up, and it also causes misalignment. There was a drawback that this was likely to occur. Furthermore, there is a problem that there is a limit to the size of the substrate to be inspected, and there is a lack of versatility regarding the size, and that it cannot be applied particularly when the substrate to be inspected is large.
しかも、全体の装置自体が大型になりメンテナンスも大
変である等種々の問題点があり、未だ一般の要求を満足
する装置は見当たらない。In addition, there are various problems such as the overall size of the device itself and the difficulty of maintenance, and no device has yet been found that satisfies general requirements.
