<p>A safety cash box comprising a housing body and a slide drawer which can be moved back and forth within the housing is disclosed, wherein the drawer can be brought into a retracted, irreversibly locked and further jammed condition when, at the occurrence of disturbing conditions, an outer pushbutton is pressed or when a remotely generated electrical signal is applied to act on an electromagnetic triggering device arranged in the safety cash box. Thus, the safety cash box according to the invention comprises first, a mechanical arrangement intended to keep the slide drawer firmly in a locked position prevented from being shifted forward and, secondly, it comprises in cooperation, backup security means which are made to go into action to cause the drawer to become forcefully wedged in place in response to mechanical failure brought about on the locking arrangement. To the effect, the shearing strength of the locking device is purposely worked out to have a breaking down point, which when exceeded by a shearing stress so applied as to have the drawer dislodged, the jamming device is put into action, BACKGROUND OF THE INVENTION Cash register are known wherein a drawer is ejected from the safe-compartment when a set of circumstances have been met. A sound signal is concomitantly generated, each time the drawer is ejected.</p> |
