Abstract

A monitoring system is arranged to monitor and record each transaction taking place on a gaming table. The system includes a tray for receiving gaming chips and sensors for sensing the chips held by the tray. A cash box is provided for the deposite of cash received in return for chips dispensed from the tray. A keyboard is provided to record each deposit of cash into the cash box. A central processing unit is responsive to a timer, the keyboard and the sensors to record each transaction which takes place on the gaming table into data storage means. A warning light lights up in the event that money which has been deposited in the cash box is not entered into the keyboard. The system enables management to conduct a complete analysis of the transactions taking place on the gaming table, to provide not only figures giving the profitability of the table but also an indication of the competance and integrity of the croupier.

Claims

1. In a gaming table or gaming environment system for monitoring the movement of money and chips on the gaming table or in the gaming environment, the system comprising;

a chip receptacle for holding chips;

means mounted on the receptacle for sensing the chips therein and providing an instantaneous count of the chips held in the chip receptacle;

keyboard means into which amounts of money received from players in return for chips can be keyed in;

data storage means;

means coupling the chip sensing means and the keyboard means to the data storage means; and

control means responsive to a trigger to cause the chip sensing means and the keyboard means respectively to feed data corresponding to the instantaneous count of chips and data corresponding to the keyed in amounts of money, into the data storage means.

2. A system according to claim 1 including a cash receptacle into which cash received from players is deposited;

detection means mounted on the cash receptacle to provide an output each time cash is deposited in the cash receptacle; and

warning means connected to the keyboard means and the detection means operable to provide a warning when money is deposited in the cash receptacle and is not keyed-into the keyboard means.

3. A system according to claim 2 including second warning means connected to monitor the chip sensing means and operable to give a warning when any change occurs in the chips stored in the chip receptacle and to provide said trigger for causing the instantaneous count of said chips to be fed into the data storage means.

4. A system according to claim 1 including;

timing means, and means connecting the timing means to the control means for causing each said transaction stored by the data storage means to be accompanied by an indication of the time of the transaction as delivered from a timer.

5. A system according to claim 1 including a portable master control unit, the master control unit including;

means for coupling the unit to the data storage means; and

means operable to interrogate said data storage means to extract from the data storage means one or more selected items of data.

6. In a gaming table having a cash receptacle and a chip receptacle, a monitoring system for monitoring the transactions on the gaming table, the system comprising;

sensing means coupled to the chip receptacle for sensing the chips in the chip receptacle and operable at any instant to provide an output signal indicative of the instantaneous cash value of the chips held in the cash receptacle, input means mounted on the table and operable to supply data indicative of the monetary value of the cash which on each occasion is deposited in the cash receptacle;

memory means;

a timer providing a signal indicative of time; and

a central processing unit, connected to the sensing means, the input means, and timer, to cause the time and details of each transaction on the table to be logged in the memory means.

7. A system according to claim 6, including;

a master control unit;

transmitting and receiving means coupling said master control unit to the central processing unit, said master control unit having controls operable to cause the data in said memory means to be transferred to said master control unit for evaluation.

8. A system according to claim 6 wherein said memory means has a predetermined storage location, and wherein said central processing unit is responsive to the input means to store the value of the deposited cash in said predetermined location in said memory means and upon each cash transaction is operable to update the value stored in said predetermined location so that it always represents the total cash deposited in said cash store.

9. A system according to claim 8 wherein said memory means has a second predetermined location and wherein said central processing unit includes summing means responsive to the sensing means and the cash value stored in said predetermined location, to sum the monetary value of the chips in the receptacle and the cash deposited in the cash receptable and to store the result in the second predetermined location in said memory means.

10. A gaming table monitoring system comprising;

a receptacle for storing chips;

sensing means coupled to the receptacle for sensing the total monetary value of chips stored in the receptacle;

a cash box for storing cash;

a keyboard for registering the cash deposited in the cash box;

detection means for detecting when on each occasion cash is deposited in the cash box;

warning means coupled to the detection means and the keyboard for providing a warning when cash deposited in the cash box is not registered on the keyboard;

a timer;

memory means;

a central processing unit;

means coupling the sensing means the keyboard and the timer to the central processing unit, the central processing unit being operative each time a change in the chips stored in the receptacle occurs and each time the keyboard is operated, to store the nature and time of transaction, as given by the timer, in the memory means; and

reading means coupled to the memory means through the central processing unit for reading the data from the memory means and supplying it in a suitable form for analysis.
