Design of the Scanner Opening
The design and placement of the scanner opening within a host enclosure
are critical for optimum system performance. A typical system uses the
scanner mounted inside a host enclosure, with an opening to allow the
scanner Field of View to exit the scanner window and read bar codes.
Use the following guidelines to design the host enclosure and scanner
opening, along with the dimensions shown in
on page 25.
•
The opening must not block any of the outgoing illumination
light, described by dimensions of the scanner Field of View.
•
Ensure that there are no reflective surfaces around the area of the
scanner opening.
•
The minimum opening size must increase as the distance
between the scanner and the host enclosure window increases.
This is necessary to accommodate the width and height of the
scan volume.
•
The opening or other parts of the host enclosure must not enter
the Field of View in order to allow the bar code image to be cap-
tured by the scanner.
•
If the scanner is flush against the opening, the opening must be
the size of the scanner at a minimum, but only exposing as much
of the front surface of the scanner as necessary.
