4.2.2 Scanner
The PT630 has provision for an integrated high performance scan engine or CCD,
and a built-in decoder for reading bar code labels. There are one
scanner-trigger
switches above the keypad. The scanning window of the integrated unit sits flush
with the top surface of the portable terminal; with the PT630 standing in a right
side up position, the scanning beam, fires off upward.
