Note
1
This option parameter consists of one byte of data, and each bit has different
meaning. (Please refer to “2.12.3-3. Mark 2”, Note 3 for the details.)
Note
*2
: The size (surface area) of the object being detected is set to the “Reflect LL.” and
“Lead Width.” field. The surface area of the lead is obtained from the following
formula:
The lead length x the lead width.
Note
*3
: The inner center position in the Y direction of the detected object lead is set at the
position offset from the component center.

The following is the actual example of the recognition and its component data. Though the
shape of the lead is not rectangular, it is possible to perform recognition of the component.

2.12.3-5. Mark – General purpose
This recognition mode is used for various components consisting of multiple parts, as shown
in
Figure 122
.
Figure 122
The target object is binarized, then the component is detected from the detected target object.
This mode can be used for recognition of the irregular shaped components.
It is possible to use the fixed threshold and the automatic threshold for binarization.
The tilt of the component is determined from the inclination of the straight lines which connect
the centers of each side.
White objects are normally recognized, but it is also possible to detect black objects on
a white background.
