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=60±10 mm from the front edge of the scanner.
・ The horizontal aiming width to the horizontal width of imaging filed of view at a distance of L=60
mm is 100%±10%.
