A conveyor device 2 for analyzer includes: a conveyance tracks 20A and 20B capable of conveying a specimen rack 3 along a fixed path; and a frame 21 positioned around the conveyance tracks 20A and 20B, the frame 21 being provided with separable and removable portions 24A and 24B which are separable and removable from the frame 21 and which are capable of providing the frame 21 with cutouts in open condition when separated and removed from the frame 21. When the frame 21 is provided with the cutouts in open condition, the cutouts allows the specimen rack 3 to be introduced onto and discharged from the conveyance tracks 20A and 20B from outer lateral sides of the frame 21 through the cutouts.

Method of detecting yarn unevenness appearing as periodic variations of a spun yarn. First, plural yarn samples are taken. Then, k distinct spectrograms are obtained according to the number of the samples. These k spectrums are averaged to create an overall spectrogram. The height of adjacent channels in the overall spectrogram are averaged to create a reference spectrogram. Either the overall spectrogram of the distinct spectrograms are compared with the reference spectrogram of find those portions of the channels that exceed the reference spectrograms in height. These exceeding portions are displayed. Therefore, realistic defective added nonuniformities contained in the spun yarn can be easily detected.

A device is provided whereby, when measuring yarn which has hairs, it is possible to detect data for the hairy part and data for the core part individually. The yarn measuring device is provided with a means which forms a Fourier transformation pattern, including a yarn core part pattern and a surface projection pattern, on a spectrum plane, by performing a Fourier transformation on diffracted laser light which has intersected and passed through traveling yarn; a first light detecting means which receives only one of the core part pattern and the surface projection pattern; and a second light detecting means which receives only the other pattern.
