7.2 Aiming Pattern
The aiming is used for the following purpose:
1. Light source for bar code reading
2. Light source to indicate the appropriate reading range
The aiming specifications are as follows:
・
An optical axis of imaging field of view and the center of horizontal aiming width coincide at a
distance of L=86±10 mm from the front edge of the scanner.
・
The horizontal aiming width to the horizontal width of imaging field of view at a distance of
L=86 mm is 100%±10%.
