DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a slot machine having unitary coin restoration system wherein a given quantity of coins can always be held while coins are caused to flow back into an internal hopper of the slot machine.
TECHNICAL BACKGROUND
For example, each of conventional slot machines disposed in a slot machine dome has an internal hopper through which coins are dispensed, entered coins are accepted, or coins paid out to a customer are accepted for circulation.
However, the capacity of the internal hopper is limited from the viewpoint of the size of the slot machine. Thus, if the customer has coins for himself or herself, the coins in the slot machine may increase. Also, the customer may take home coins that are paid out, in which case the number of coins in the slot machine decreases. When the coins in the slot machine increase or decrease substantially, the slot machine must be stopped in order to take out coins from the internal hopper or replenish the internal hopper with coins. This job causes personnel in the gaming house a lot of trouble and is inconvenient to the customer. Moreover the availability of the slot machine deteriorates.
DISCLOSURE OF INVENTION
It is therefore an object of the invention to provide a slot machine designed so that the number of coins in an internal hopper in the slot machine can always be maintained at a given quantity.
To this end, according to the invention, there is provided a slot machine having unitary coin restoration system comprising a game execution system for executing a game, a coin dispensing/adjustment system for dispensing coins and making adjustment, and a coin handling system, characterized in that the coin handling system comprises: outside; hopper; and the coin storage tank for adjusting a quantity of coins held in the internal hopper.
The coin storage tank can be disposed under the internal hopper.
The adjustment mechanism can comprises an overflow passage for introducing coins exceeding an upper quantity limit in the internal hopper into the coin storage tank and a transport mechanism for transporting coins stored in the coin storage tank to the internal hopper.
The adjustment mechanism can further include a lower limit sensor for detecting that the internal hopper holds a lower limit quantity of coins and an upper limit sensor for detecting that the internal hopper holds an upper limit quantity of coins in the internal hopper.
The adjustment mechanism can further include a controller for controlling driving of the transport mechanism.
The controller can have means for reading an output of the lower limit sensor in the internal hopper, and as a result of the lower limit sensor detecting that the quantity of coins held in the internal hopper has reached a lower limit, driving the transport mechanism, and for reading an output of the upper limit sensor and as a result of the upper limit sensor detecting that the quantity of coins held has reached an upper limit, stopping the driving of the transporter.
The adjustment mechanism can further include a lower limit sensor for detecting that the coin storage tank is holding a number of coins that is at a lower limit and an upper limit sensor for detecting that the coin storage tank is holding a number of coins that is at an upper limit.
The controller can further include means for reading an output of the lower limit sensor in the coin storage tank, and as a result of the lower limit sensor detecting that the quantity of coins stored in the coin storage tank has reached a lower limit, outputting information indicating that the coin quantity is insufficient, and for reading an output of the upper limit sensor and as a result of the upper limit sensor detecting that the quantity of coins stored has reached an upper limit, outputting information indicating that the coin quantity is excessive.
The adjustment mechanism can further include a condition display for displaying information indicating conditions of the slot machine.
The adjustment mechanism can further include a proper quantity sensor
