A display displays the assigned monetary value of each gaming chip. The total value of a collection of chips is evaluated by counting the number of chips for each type, and calculating the monetary value of each gaming chip type using the assigned monetary value.

Description:
INTRODUCTION AND BACKGROUND 
     The present invention relates to gaming and in particular to handling and evaluating gaming chips. 
     The invention is primarily intended for use on casino floors with table games which involve the use of a mixture of different types of gaming chip. Typically, each different type of gaming chip is pre-assigned a certain monetary value and the chips are distinguished by shape and/or colour. However, it is also known to use chips which are assigned to a particular player and are given a certain value at the start of the game. Thus a player may elect to use chips of a particular colour and shape and have a particular value assigned to them. He may also chose to change the value during the game. It is often necessary between or during the course of such games to have a quick and easy way of evaluating the use of the gaming chips. 
     SUMMARY OF THE INVENTION 
     In a first aspect, the invention provides a gaming chip system for indicating the value of gaming chips. Different chips are represented and assigned a monetary value, which is then displayed. 
     In a second aspect, the invention provides a gaming chip system for evaluating a collection of gaming chips. Means is provided for representing a plurality of different gaming chips, and means for assigning monetary values to each of the different gaming chips. A display displays the assigned monetary value of each gaming chip and evaluating means counts the number of chips for each type, and calculates the monetary value of each gaming chip type using monetary values assigned by the assigning means. 
     The present invention provides a quick and simple way of assigning values to the different gaming chips. The different types of gaming chip may be represented by the system in a number of different ways. A particularly convenient way of representing the gaming chips is provided if the different types of gaming chip can be attached to the gaming system. Therefore, it is preferable if the means for representing a plurality of gaming chips comprises means for attaching a plurality of different gaming chips to the gaming system. This has the advantage, that the gaming system can be used with a variety of different gaming chips. Hence, the gaming system may be used with many different varieties of gaming chip. 
     It is also preferably if both the players and a game supervisor can read the values assigned to the different types of gaming chip. Therefore, it is preferably if the means for representing a plurality of different gaming chips provides a double sided display. Similarly, it is preferable if the first display means are double sided. 
     The values assigned to each different type of gaming chip are displayed by the first display means. These are located in the vicinity of the representation of the gaming chip to which they correspond. It is preferably that the first display means displays alpha numeric characters. Therefore, the first display mean may be used to display either the value assigned to each different gaming chip or the status of each gaming chip. For example, the first display means may be used to indicate if a gaming chip is free for selection by a player or if it is already in use. 
     A monetary value may be assigned to a chip in a number of ways. In many table games, it is preferable if the different types of gaming chip can only take on a certain value from a predetermined range. For example, in Britain, the values may be 25p, 50p, £1, £2, £2.50, £5, £10, £20, £50. Therefore, it is preferable if means are provided for incrementing the assigned monetary value through a range of predetermined values. The values are incremented in ranges according to the country of installation 
     The gaming chip system may be used with other components on a casino floor. Therefore, it is preferable if communication means are provided so that the assigned monetary value of a particular chip can be communicated to another component. For example, a component which validates the choice of assigned monetary value. 
     At the end of a game or sequence of games, the assigned monetary values may need to be reset. This can be conveniently done if a clear button is provided which clears all of the assigned monetary values. Therefore, it is preferable if the system further comprises means for clearing or zeroing the assigned monetary values of each of the different gaming chips and indicate that they are available for use. It is also preferable if this clear button when pressed allows the communication means to transmit a signal to another component to clear or zero all values previously communicating to the other component by the gaming system. 
     The use of the gaming system is regulated by a supervisor. To avoid players changing the assigned values while the supervisor is distracted, it is preferable if the gaming system further comprises security means. The security means can be simply implemented by providing a switch which disables the means to assigned monetary values. The switch, can only be operated by the supervisor. In order to show whether or not the security means are switched on or off, it is preferable to have a security indicator e.g. a light, which indicates when the assigned values may be changed. It is also preferable of the security status can be communicated to another component e.g. a validation system.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     An arrangement for the gaming chip system is shown in FIG.  1 . The gaming chip system comprises an indicator  1  which is in electrical contact with a gaming chip collector  3 . The indicator  1 , will be described in more detail later in relation to FIG. 2. A mixture of gaming chips  5 , is shown entering the opening  7  of the gaming chip collector  3 . The mixture of gaming chips  5  enters the gaming chip collector  3  and falls to the base  11 . The gaming chip collector  3 , is shown with a long narrow opening channel  9 . This is to prevent extraction of the gaming chips from the gaming chip collector by unauthorised personnel. Once the gaming chips  5  are within the gaming chip collector  3  they are sorted, counted and then evaluated using information derived from the indicator  1 . Such collectors for sorting and counting gaming chips are known per se. 
     FIG. 2, shows an indicator  1  according to the present invention. On the front surface  31  of the indicator  1 , there is provided both means to a represent the different types of gaming chip  21  and display means  29  to display the values assigned to each of the different gaming chips. In the embodiment shown here, a plurality of different types of gaming chip may be attached to the front surface  31  of the indicator  1  via the means to represent the different types of gaming chip  21 . The attached gaming chips are located above the display means  29 , such that the value assigned to each gaming chip is clearly displayed below each type of gaming chip displayed. 
     Value change buttons  25  are located on the top surface  33  of the indicator  1  to assign a value to each of the different gaming chips. One button  25  is provided for each different gaming chip displayed. Each value change button  25  is located directly above each of the different types of gaming chips displayed. Pressing the button  25  once results in the assigned value of the chip being incremented by a predetermined value. For example, the chips may only be able to take a series of values, 25p, 50p, £1.00, £2.00, £5.00, £10.00, £20.00, £50.00 etc. Each time one of the buttons  25  is pressed the assigned value increments to the next value in the series. 
     On the right hand side  35  of the indicator  2  there is provided a security key  23 . Located above the security key there is a clear button  27 . A security light  28  is located above the clear button. The function of the security key  23  and the security light  28  will be discussed later. The clear button  27  forms part of the means to assign values to each of the gaming chips. When the clear button  27  is pressed, the values assigned to each of the different gaming chips is set back to zero and each of the value indicators display ‘----’. 
     The security key  23  is present to prevent a person who is not authorised changing the monetary values assigned to each of the different chips. When the key is turned to the locked position the value change buttons  25  cannot be used to change the assigned monetary values i.e. the values are locked. In the locked position, the key can be removed from the indicator. The security light  28  is lit when the values are locked. 
     FIG. 3 shows the indicator  1  and collecting means  3  of the present invention integrated with a number of components which may be used on a casino floor for roulette. The indicator  1  and the chip counter  5  are connected via interface  51 . Also connected to the system via the interface  51  are an overhead optical sensor  53 , winning number display apparatus  55  and a financial and statistical computer (PC)  57 . 
     The indicator  1  of the system is connected to the financial and statistical PC  57  via the Interface  51 . One of the many function of the PC is to validate the monetary value of each type of gaming chip set by the indicator  1 . Each of the assigned monetary values is communicated from the indicator  1  via its communications port and the interface  51  to the PC  57 . The PC  57  can then allow or disallow the required assigned monetary value. Therefore, the range of possible monetary vales for each of the different types of gaming chips can be further restricted. The indicator  1  can also transmit information about its security status via its communications port to the PC. 
     The chip counter  3 , also transmits information via the interface to the PC  57 . The chip collector  3  sorts and counts the collection of gaming chips which it holds. The PC provides display means to display this information if required. The PC further keeps a check on the different types of chips counted and can use this information to restrict the monetary values assigned by the indicator  1 . 
     FIG. 3, shows the present invention connected to a table game. The overhead optical sensor  53  functions to read the winning number from a roulette wheel and inputs the data into the interface  51 . The interface then outputs the winning number to the winning number display apparatus  55 . The data received from the sensor  53  along with the chip collector allows a supervisor to quickly check the financial gain or loss of the table as a while or the amount staked using particular chips, and hence by an individual player, during a game. 
     In light of this disclosure, modifications of the described embodiment, as well as other embodiments, all within the scope of the present invention defined by the appended claims, will now become apparent to a person skilled in the art.
