Abstract
A check out stand (20) having a telescoping take-away conveyor (26) extending between a front module (22) and a rear module (24). Retraction of the telescoping take-away conveyor (26) allows an area located beneath the leading end of the conveyor to be exposed. The exposed area can support a single bag (85) for bagging groceries and other items. If the telescoping take-away conveyor (26) isretracted only a limited amount, the single bag (85) may be inserted between theleading end of the telescoping take-away conveyor (26) and the trailing end of the scanner (32). The telescoping take-away conveyor (26) utilizes a friction roller (66) that permits the powered roller (60) for the telescoping take-away conveyor (26).
