DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new cash register alarm system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 4, the cash register alarm system 10 generally comprises a cash drawer 11 having a back wall 13 and a bottom wall 12, and further comprises a tray 15 having a bottom wall 16 and a back wall 17 and being removeably disposed upon the bottom wall 12 of the cash drawer 11 with the tray 15 further having a plurality of partitions 19 spaced apart and forming compartments 20 in the tray 15. A plurality of sensors 22 are conventionally disposed in the compartments 20 and in the bottom wall 16 of the tray 15 for detecting whether the compartments 20 have any paper money contained therein. A plurality of electrical current contact members 14,18 are securely and conventionally disposed upon the back wall 17 of the tray 15 and upon the back wall 13 of the cash drawer 11. The electrical current contact members 18 disposed upon the tray 15 are connected to the sensors 22 with wires 21, and the electrical current contact members 14 disposed upon the cash drawer 11 are connected to the alarm system with wires 21. Each of the electrical current contact members 18 of the tray 15 is in contactable relationship with a respective one of the electrical current contact members 18 of the cash drawer 11. The sensors 22 are connected to one another in series such that more than one of the sensors 22 would need to be actuated before an electrical impulse would be transmitted to the alarm system. The sensors 22 are essentially light-sensitive detectors which are actuated when they are exposed to light when the compartments 20 have no paper money to block the light to the sensors 22. The light-sensitive detectors are interconnected with wires 21 with the electrical current contact members 18 of the tray 15 being conventionally disposed on an exterior of the back wall 17 thereof, and the electrical current contact members 14 of the cash drawer 11 being conventionally disposed on an interior of the back wall 13 thereof. Each of the electrical current contact members 14 of the cash drawer 11 are aligned and are in contactable relationship with a respective one of the electrical current contact members 18 of the tray 15 so that the alarm system is connected to the sensors 22.
In use, the tray 15 is placed in the cash drawer 11 so that the electrical current contact members 14,18 of the tray 15 and the cash drawer 11 are touching and in contact with one another to create a complete circuit from the sensors 22 to the alarm system. In order not to actuate the alarm system, the user places paper money in the compartments 20 over the sensors 22 thus blocking out light to the sensors 22. More than one of the compartments 20 would have to be emptied of the paper money before the alarm system would be actuated.
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
