Abstract

A method of producing a sample collection apparatus, including steps of: attaching a holding member to a support of a nozzle unit such that, in slits provided with N edges (N≥3), a collection range w of a sample tube is included within a range from a lower-limit position at a distance w/2 from a 1st edge toward an initial-position, to an upper-limit position at a distance w/2 from an Nth edge away from the initial position; loading the sample tube on the holding member; counting the number of pulses with which a pulse motor is driven to move a nozzle to the center of the collection range; identifying the signal corresponding to the last edge recognized by a photo-interrupter before the nozzle reaches the center of the collection range; and storing the number of pulses and the signal corresponding to the last edge in a storage device.
