As the component has leads in the N/S direction, the value “1” is set to “Lead Number N/S” in
order to avoid line detection in the N/S direction.
As a result, recognition is carried out only in the right/left (E/W) direction.
The following shows the recognition results of the actual component (trimmer capacitor).
Recognition was performed only in the left/right (W/E) direction for these components.

In the example of recognition shown in Figure 128, the function that cuts noise inside
the component (See “Appendix 1. Noise processing”.) was used to reduce the effects of the
dark portion at the top.
(A numeric value is set for the component inside noise cut function.)
2.12.4-1. Special recognition of special quad
There are a number of special recognition algorithms available in the Sp Quad
Recognition mode.
(1) Normal: No restriction on the range of value.
(Special components, Special shape, Sp Quad, Normal)
(2) Special 1: Not supported (Lead Width, Lead Pitch check exist)
(3) Special 2: Not supported (hole position check)
(4) Special 3: Check Direction --- The direction is judged based on the brightness of the
specified range (circle). (* This needs to be custom ordered.)
Option 1: Recognition flag
Option 2: Min. Brightness Difference (If the value is 0, 50 is set)
If the difference of the average brightness of the detected circle is less than the
value specified here, it is determined to be an error.
The detection circle is set in the Lead Groups specified by the bit 7,5 and 4 in
Option 1 in order to determine the direction.
- Lead Group: 1 (When set to Lead Group 2, specify 2)
- Lead Number: 0
- Reflect LL: 0
- Lead width: Diameter of detection circle (mm)
- Lead pitch: 0
- Find Pos. X: Detection circle center position X
- Find Pos. Y: Detection circle center position Y
Based on the results of each direction, add +90°, +180° or +270° to the tilt of the
component and set the values.
