Operatiton (sample disk)
Outer track :........................................35 positions For routine and stat samples
Inner track : 25 positions...............For control serum, standard solution, detergent (W1, W2, W3)
(position-free except detergent)
(1) Definition of Control Variable
Represented by optional position POS # (x, y) on the S. disk.
x: Track variable (1: outer track, 2: inner track)
y: Position variable (1 to 35: outer track, 1 to 25: inner track)
(2) Rotation Control System
In rotation from POS #1 (x, y) to POS #2 (x', y'), the sample disk stops at position POS2-1
(x'-1, y'-1), is fed 1 pitch (back) and stops the next position (sampling position).
(a) x = x’ fore : θ (back) ≥ θ (fore)
back : θ (back) < θ (fore)
(b) x = x' The sample disk rotates in order of POS #N (x, y) → POS #N (n, m) (nearby
intermediary position in direction determined in (1)) → POS #2 (x'-1, y'-1) →
POS #2 (x', y').
The direction of rotation is determined in the same manner as in (1). Note
that the sample disk moves back when POS #N (n, m) is ahead of POS #2-
1 (x'-1, y'-1) in the above direction of rotation.
NOTE: θ is an angle between the current position and one position before the
destination.
For rotation and stop in one cycle, refer to the following page.
