(2) Details of Type Data
Type Name Type ID Nos.
This represents the regulated ID No. for type display regulation in the
"T
ype Listup" window.
The regulated ID Nos. are classied in the external le of the related
data.
When the program is executed, the contents of this le is read and
registered in the regulation list box in the "Type Listup" window.
Inspection Type No.
Specify the number which represents the contents (method) of accuracy
inspection.

1: Inspection of Lane Origin Of
fset Adjustment
The origin offset position is inspected based on the design value
(position) of the target pickup hole.
The value is measured only in the Y-axis direction.
When the initial pickup hole is not located in the image processing
area, the position is shifted in the Y direction as much as the
"Camera Correction Pitch" specied in the system setting data.
The inspection position is moved to the place where the image
processing become possible.
As a result, the offset value for adjustment is calculated according
to the "CENTER" value (center value between "MAX." and "MIN."
values).
•
2: Inspection of Fiducial Mark Position
Adjustment
An inspection is made to correct the pickup hole dislocated from the
ducial mark position.
The conrmation is made through the image processing of the
ducial mark before the pickup mark is inspected and the deviation
from the design value is stored in memory.
The pickup hole is inspected at the position where the pickup hole is
corrected as much as the shifted distance of the ducial mark.
The result of the measurement through the image processing of the
X and Y axes will be the result of correction equivalent to the
shifted distance of the ducial mark.
The result is displayed and "MAX.", "MIN.", "RANGE", and
"CENTER" values are displayed for each lane as the nal result.
Based on the "CENTER" value for each row (displayed here), the
value for feeder adjustment must be specied.

3: Simultaneous Inspections "1" and "2"
The lane origin offset and ducial mark position adjustments are
inspected at the same time.
The origin of
fset value for the Y axis is calculated according to the
shifted distance of the pickup hole based on the design value and
the shifted distances of the X and Y axes from the ducial mark are
recalculated and displayed after being inspected.
Each value displayed during the inspection represents the result of
image processing based on the position moved to the rst pickup
hole.
After all specied pickup holes have been inspected, the origin
offsets are gured out and the distances shifted from the ducial
mark are also calculated based on the result of origin offset
correction and redisplayed.
The results of judgment are based on the values obtained after this
recalculation.
(3) Type Change
The type change method can be divided roughly into "Automatic Type
Change" and "Manual Type Change".
Automatic T
ype Change
After a certain type and serial No. are read, the corresponding type is
selected automatically.
In the type retrieval process, it is checked if the read type exists or not
by using the type name of the type data.
When the specied type data is the same as the read one, no type retrieval
is made.
When the required type cannot be retrieved automatically, it is
required to create it.

When the "T
ype Setting" window is active, press the [Setting]
button.
The "Type Listup" window opens.
Use the [Page Selection] or [Cursor Movement] button to move the
subcursor to the target type No.
The subcursor can also be moved by clicking the scroll bar, directly the No. of
the pertinent line in the list, or the type name area.
Press the [Type Change] button.
The type data corresponding to the No. specied by the subcursor is
called and displayed.
