ABSTRACT:
A battery-powered device, especially a hand-held, data collection terminal having an electro-optical scanner, includes a main housing, a battery pack separate from the main housing, and a latching mechanism for latching the battery pack in its assembled position on the main housing in which it is partially received in a correspondingly configured receiving recess of the main housing. Electrical circuitry in the device is shut down prior to battery pack removal. During idle periods, the device is supported on a cradle, with a back or handle portion of the device being received in a main compartment of the cradle. The cradle also includes an auxiliary compartment for receiving the battery pack for recharging the same. A hook-shaped projection of the cradle engages behind a detaining wall of the housing and is held in position by a shuttle that, in its locking position, is interposed between such projection and an unyieldable portion of the housing and is locked in place by a padlock passing through aligned openings of the shuttle and of the cradle.
