ABSTRACT:
Embodiments of improvements to a money clip alarm system of a cashier's drawer are disclosed. In one embodiment, a terminal contact block device is mounted to the drawer tray and a non-shorting feed through spring contact block device is mounted to the drawer housing. When the contact block devices are not touching, the electrical path from the money clip to the remote alarm automatically disconnects allowing convenient removal of the drawer tray from the drawer housing. A second embodiment includes a push button switch which changes state when the drawer tray is removed from the drawer housing providing an alternative electrical path from the drawer housing to the remote alarm and preventing activation of the remote alarm system. The preferred embodiment includes a magnetic switch in place of the push button switch mounted between the drawer tray and the drawer housing. Further, a delaying circuit is added to the alarm circuit which prevents immediate activation of the remote alarm when the drawer tray is removed allowing the magnetic switch to activate and also preventing immediate activation of the remote alarm when the money is removed from the money clip accidentally, allowing the employee a few seconds to replace it. One preferred embodiment also includes a shorting feed through spring contact block device in place of the non-shorting feed through spring contact block device which also provides an alternative electrical path when the drawer tray is removed.
