[0026]

As described above, according to the present invention, when inspecting the holder assembly, it is possible to detect the presence or absence of an optional member that is fixed or not fixed according to the specification. Even in the case of small-volume production, it is possible to surely inspect whether the specifications of the holder assembly are as specified or not, without erroneous specification of the product.

In addition, in the case where the displacement detecting means is provided, there is an advantage that it is possible to perform an improper assembly of the holder assembly. Further, when the locking means, the unlocking means, and the urging means are provided, the locking means locks the position detecting means in the inspection posture at the time of inspection, and detects the positional deviation in the holder assembly which has been displaced. When the abutting portion of the means abuts, the biasing force of the biasing means forcibly returns the misalignment detecting means to the release position. Can be easily unlocked by the unlocking means and the holder assembly can be removed, but if the misaligned holder assembly is inspected, the lock will not be locked, so that the operator can remove the holder assembly. Pass / fail can be identified by the mechanical behavior of the displacement detection means, and there is an advantage that the determination is facilitated.
