The present invention relates to gaming devices. More particularly, the present invention relates to wagering gaming device displays.
Gaming devices provide fun and excitement to the player. Gaming, in general, provides an escape from the everyday rigors of life. Gaming devices and gaming establishments use bright lights and exciting sounds to set the gaming world apart from the rest of the world. Gaming devices, in particular, use one or more displays that enable the player to see and play the game. The displays typically portray the action of the game and ultimately indicate whether or not the player wins.
Slot machine displays have gone through a number of transitions since their inception in the late 1800's. Originally, slot machines displayed purely mechanical reels. While these machines gained enormous popularity, the mechanical nature of the reels limited the number of paystops, which limited the number of different symbols and the number of different winning symbol combinations.
The advent of the computer and the video monitor expanded the possibilities for gaming devices. There are now video poker, video blackjack and other types of video gaming machines. Video displays have also been implemented in slot machines. The video slot machines use computers to randomly generate symbol combinations from an expanded number of different symbols. Video reel strips can include a virtually unlimited number of symbols, which enables a wide variety of different symbol combinations to be employed, including combinations that appear very infrequently and yield high payouts.
With slot machines, the video monitors have also been used to provide bonus or secondary games. Bonus games have become much more prevalent and elaborate in recent years. Players play the base game of slot until becoming eligible for a bonus game. The base game temporarily pauses, while the player plays the bonus game. When the player completes the bonus game, the gaming device returns the player to the base, slot game.
It should therefore be appreciated that a single video monitor is often sufficient to provide both the base game of slot and one or more bonus games that become triggered by the slot game. As seen in
Video monitors and in particular video-based slot machines are likely going to continue growing in popularity. As the video monitor has been used more and more, however, there has been a growing sentiment that some of the mystique of the old time mechanical gaming devices is lost when mechanical reels and mechanical displays are replaced by a video monitor. Manufacturers have attempted to create a nostalgic feeling in gaming devices, for example, by implementing “ding, ding” sounds (i.e., credit roll-up sounds) to simulate the sound of coins hitting a tray (when the gaming device is in reality incrementing an electronic credit meter).
Accordingly, a need exists to provide a gaming device that may use a video monitor, which provides increased flexibility to the gaming device to add more symbols and more elaborate bonus games, while providing some aspect of the gaming device that is mechanical and provides a fun and exciting mechanical display.
The present invention provides a mechanical display and indication for wagering gaming devices. The present invention includes various embodiments, each of which have a number of common elements. First, the embodiments each include a set of symbols or indicia such as conventional gaming symbols, values or value symbols, prizes or prize symbols, awards or award symbols, or credits or credit symbols. Second, each of the embodiments include a plurality of radially spaced apart translating or oscillating indicators such as arrows. The indicators translate or oscillate radially and sequentially, each pointing at one point towards a respective, associated symbol. The player can see each symbol and thus is able to know which symbols are relatively better than others. The radially translating indicators provide a random, visual element to the outcome, wherein the player watches the different indicators sequentially point to different symbols until the motion stops, leaving a single indicated symbol, which is provided in a suitable fashion to the player.
The gaming devices operable with the present invention include but are not limited to the games of slot, poker, keno and blackjack. The display and indicators of the present invention operate with the base games of slot, poker, keno and blackjack and/or any bonus game, bonus triggering event, progressive game or any other type of secondary game thereof. The display and indicators can be constructed of any suitable material(s), such as metal, plastic, wood and any combination thereof.
In one preferred embodiment, the display and indicators of the present invention operate with the primary game of slot and in particular a bonus game that operates in conjunction with slot. That is, one or more indicators of the present invention point to or indicate an award provided to the player that is in addition to the winnings from the regular slot game. The symbols indicated by the display can, for example, represent any suitable type of award or benefit for the player, such as base game credits, a multiplier of a base game credit, a number of picks from a prize pool or a number of free spins or free games. The indicia or symbol can also signal the player's entry into a bonus game or into a different area or part of the base game.
In one preferred embodiment of the present invention, the symbols are each provided by an independently operated symbol display. Each of the plurality of symbol displays is controlled by the processor and is operated to display a plurality of different symbols such as award or credit values. In one embodiment, the symbol displays are conventional LED devices, although it should be appreciated that the symbol displays may be any suitable display devices, including but not limited to video monitors, wheels, reels and the like. The symbol displays facilitate the change of the symbols. The change of the symbols could be randomly determined, predetermined, based on different award levels or determined in any other suitable manner.
For purposes of describing the present invention, the term symbol includes any suitable symbol such as conventional gaming device symbols or images such as a number of credits, an award, a prize value, letters or playing cards.
In one primary embodiment of the present invention, the display includes a number of radially spaced apart symbols. For example, the symbols can appear as numbers on a clock, albeit having different amounts than one to twelve. An indicator, such as an arrow is provided for each symbol. The indicators are positioned to point radially outward toward the symbols. The player viewing the display of the present invention sees the symbols and the indicators.
The display can be mounted in any suitable position on the front, sides or top of the cabinet of the gaming device. In one embodiment, the display includes a cam and a series of cam followers, one follower for each indicator mounted in the cabinet. The display also defines radially spaced apart grooves, one groove for each indicator and follower. Each follower includes a connector that extends through one of the grooves and is attached to one of the indicators. In this embodiment, the followers are spring-loaded and biased to be normally in a non-indicating position, wherein the indicators are positioned a furthest possible position away from the respective symbols. The cam is attached to an axis of rotation or camshaft located at the radial center between the symbols. The cam has any suitable shape desired by the implementor, such as an egg shape, that biases some of the indicators partially radially towards the respective symbols and one of the indicators to an indication position, closest to one of the symbols.
In one embodiment, the cam includes protrusions or extensions that make certain of the indicators appear to wiggle. The cam and followers produce a cyclical, repeatable motion of the indicators, wherein the player viewing the display can learn the pattern and can predict which follower or indicator will begin to move next. The camshaft is connected to an actuator such as a motor, and specifically such as a stepper motor, which precisely controls the acceleration, velocity and position of the cam and therefore controls precisely the relative positions of the indicators with respect to the symbols.
In another embodiment, a different cam arrangement is employed using a circular cam and a connection point on the cam spaced radially away from the center of the circular cam. The connection point includes the connection or each of a set of members extending from the point to the respective indicators. As the circular cam rotates, the connection point circumferentially moves about the center of the cam. The members and indicators are simultaneously directed or pushed toward and directed or pulled away from their respective symbols. The indicators translate along radially spaced apart or spoked grooves in the panel of the gaming device, as with the previous embodiment. The indicators are in constant motion and are either moving sequentially toward or away from the symbols.
In one alternative embodiment, the drive mechanism of the cam and followers is replaced by separate stepper motors, one for each indicator. In such embodiments, the stepper motors are linear stepper motors or alternatively can be rotational motors that are connected respectively to lead screw arrangements. In either case, the stepper motors drive connectors that are attached through the grooves in the panel to the indicators in the same manner as the followers in the cam driven embodiment. In the case where lead screws are employed, the connectors include mating threads that thread onto the lead screws.
This multiple stepper motor embodiment facilitates independent control of each of the indicators. The indicators can be of any suitable desired shape, such as arrows, stars or lightning bolts. In one embodiment, the indicators are part of a three-dimensional object, for example, the tentacles of an octopus. The stepper motors provide the implementor with the ability to move the tentacles individually and independently at different speeds and at different accelerations. The result is a very entertaining three-dimensional display. Unlike the cam embodiment, any of the tentacles or indicators can reside in any position between a fully non-indicating position and a fully indicating position at any suitable time.
In each of the above-described embodiments, after a period of time, the motion of the indicators stops and one indicator is left closest to its respective symbol. The gaming device uses the indicated symbol in some manner, such as providing a number of base game credits to the player, providing a number of free games or free spins, providing a number of picks from a prize pool, allowing the player to enter a bonus game, incrementing a progressive jackpot and any combination thereof.
Additional features and advantages of the present invention are described in, and will be apparent from, the following Detailed Description of the Invention and the figures.
The present invention provides a display and display indicators that operate with a wagering game such as slot, poker, keno and blackjack. In an embodiment, the display and indicators operate in conjunction with bonus games, which in turn operate in conjunction with the base games of the wagering gaming device such as slot, poker, keno and blackjack. Besides the base and bonus games, the present invention can operate with any of the bonus triggering events, as well as any progressive game coordinating with these base games. The symbols and indicia used for any of the base, bonus and progressive games include mechanical, electrical or video symbols and indicia.
One primary embodiment for the display and display indicators is with the game of slot. Referring now to the drawings, and in particular to
Gaming device 10 includes monetary input devices.
As shown in
Gaming device 10 also includes one or more display devices. The embodiments shown in
The display and display indication of the present invention is provided, in an embodiment, in the upper display area 32 of gaming device 10a and 10b of
The slot machine embodiment of gaming device 10 includes a plurality of reels 34, for example three to five reels 34. Each reel 34 includes a plurality of indicia such as bells, hearts, fruits, numbers, letters, bars or other images which correspond to a theme associated with the gaming device 10. If the reels 34 are in video form, the display device displaying the video reels 34 is, in one embodiment, a video monitor. Gaming device 10 also preferably includes speakers 36 for making sounds associated with the gaming device or play thereof or playing music.
With reference to the slot machine base game of
In addition to winning base game credits, the gaming device 10, including any of the base games disclosed above, also includes bonus games that give players the opportunity to win credits. The gaming device 10 employs a video-based display device 30 or 32 for the bonus games. The bonus games include a program that automatically begins when the player achieves a qualifying condition in the base game.

As illustrated in
The processor 38 also controls the output of one of more motion controllers 56 that control one or more actuators or motion producing devices 58. The motion producing devices 58 can be any suitable combination of motors, stepper motors, linear stepper motors or other types of linear actuators. The motion controllers 56 typically include printed circuit boards or standalone enclosures that receive high level commands from the processor 38. The motion controller 56 converts the high level commands, for example, into a number of step pulses, which in turn are converted into motor currents. The stepper motor or other type of motion producing device 58 receives the currents, wherein the currents cause, for example, a rotor to turn within a stator a precise and desired amount.
As described more fully below, the rotational motion of a motor 58 can be used to rotate a portion of the display or indicator of the present invention. The rotational motion can alternatively be converted to cause a portion of the display or indicator to translate. Otherwise, a linear motion producing device 58 can be used to directly cause a portion of the display or indicator of the present invention to translate.
The motion control scheme facilitates complex movements of multiple parts to be programmed into the memory device 40 and carried out by the processor 38 at the appropriate time in the sequence of the game, be it a base, bonus, bonus triggering or progressive sequence of gaming device 10. Moreover, multiple programs can be implemented in the memory device 40, wherein the processor runs the appropriate program at the appropriate time, and wherein the displays and indicators described below can perform or move differently, such as faster, slower or in different directions at different times or points in the game. The motion control programs, in one embodiment, interface with one or more random generation devices, typically software based items, to produce randomly displayed outcomes on the displays and indicators of the present invention.

The display 60 in an embodiment is mounted on the upper display area 32 illustrated in
Each of the indicators 62 to 84 translates radially along a slot 88. The panel of upper display area 32 defines the slots. The panel of the upper display area 32 can be metal, plastic, wood, etc., and can have indicia and other items designed to hide, cover or de-emphasize the slots 88. The display and indicators can be constructed of any suitable material(s), such as metal, plastic, wood and any combination thereof.
Referring now to
The display 60 includes a cam 90. The cam 90 illustrates one possible shape and thus one possible motion profile for the display 60 of the present invention. The cam 90 is attached to a camshaft 92 which is driven by a motion producing device 58 (
The present invention can use one or more stepper motors having a rotational or translational output. In the illustrated embodiment, the camshaft 92 of the display 60 is mounted via a motor coupler (not illustrated) to a rotational stepper motor. The motor coupler in an embodiment has a spring portion that allows for slight misalignment between the shaft of the stepper motor and the camshaft 92.
Each of the indicators 62 to 84 is mounted via a connector (
Pistons 102 provide support for a spring 98. The springs 98 are sized and selected so as to provide a sufficient amount of force to push the cylinder 94 and follower 96 against the cam 90. The springs bias against a wall 104 affixed to the panel of the upper display area 32. The springs 98 can alternatively be housed on the inside of the cylinders 94.
As discussed above, the cylinders 94 attach to connectors (
In the illustrated embodiment, the cam 90 is oblong or egg-shaped so that when cam 90 rotates about the access or camshaft 92, certain of the cylinders 94 and the corresponding indicators are more biased than others against the springs 98, which are held in place by the pistons 102. In the illustrated embodiment, the cylinder 94 and the corresponding indicator 62 are pushed a maximum distance towards the wall 104. On the front face of the panel of the upper display area 32, the indicator 62 appears closest to its associated symbol 86. The indicators 64 and 84 that are most closely adjacent to the indicator 62 are biased towards their respective symbols 86 a distance slightly less than the distance of the indicator 62. The indicators 66, 68, 80 and 82 are biased by the cam 90 even less than the adjacent indicators 64 and 84.
The bottom of cam 90 is virtually circular, which results in the indicators 70, 72, 74, 76 and 78 all being at substantially equal distances from their respective symbols 86. The cam driven display 60 produces an effect, wherein the indicators 62 to 84 are in constant motion except where the radius of the cam does not change over a period of degrees. It should be appreciated that the cam 90 can be rotated in either direction, stopped, reversed, and accelerated at any rate to achieve any velocity capable by the stepper motor.

The display 260 of
Referring now to
The display 360 does not include a spring-loading or banded mechanism as described above. The display 360 instead uses a cam 380 and an off-center connection point 382. The off-center connection point 382 rotates circumferentially at a predetermined radius about the center of the cam 380.
The off-center connection point 382 is pivotally connected to members 392 to 402. Each of the members 392 to 402 is pivotally connected to one of the indicators. In particular, the member 392 is pivotally connected to the off-center connection point 382 and the indicator 362. The member 394 is pivotally connected to the point 382 and the indicator 364. The member 396 is pivotally connected to the point 382 and the indicator 366. The member 398 is pivotally connected to the point 382 and the indicator 368. The member 400 is pivotally connected to the point 382 and the indicator 370 and the member 402 is pivotally connected to the point 382 and the indicator 372.
When the cam 380 rotates about its center 384, the off-center connection point 382 of the cam 380 drives the members 392 to 402 in different directions. In the illustrated embodiment, the connection point 382 of the cam 380 pushes the member 398 the furthest outwardly of any of the indicators 362 to 372, wherein the indicator 368 extends towards the symbol 86 of three hundred thirty. The display 360 currently indicates that if an award provided to the player at this instant in time would be the value of three hundred thirty.
The connection point 382 also pushes the members 396 and 400 and their corresponding indicators 366 and 370 slightly less than the indicator 368 towards the symbols 86 of twelve and forty-five, respectively. The connection point 382 pulls the members 402, 392 and 394 and the indicators 372, 362 and 364, respectively, away from the symbols 86 of fifty, “BONUS” and five, respectively. It should therefore be appreciated that the indicators 362 to 372 are in virtual constant translating motion towards and away from the symbols 86.
The center 384 of cam 380 has a camshaft 384 that extends through the panel of upper area 32 and couples, e.g., via a motor coupler having offset compensation, to a motion producing device 58, such as a stepper motor. The stepper motor (not illustrated) precisely controls the acceleration, velocity and position of the off-center connection point 382 with respect to a reference, such as zero degrees.
In one embodiment, the gaming device 10 provides a benefit to the player based on at least one of the symbols 86 to the player when the display rotates and then stops rotating. The indicator closest to its respective symbol designates the symbol that gaming device 10 provides to the player. For example, in
It should be appreciated that in an alternative embodiment, the indicators could indicate multiple different symbols and the awards associated with the multiple indicated symbols could be provided to the player. It should also be appreciated that one or more of the symbols could represent a triggering event for another game such as a secondary game, which is operable to provide further awards to a player. This secondary game could be in any suitable form such as a wheel, reel or other display device.
Gaming device 10 includes a method of determining or knowing which indicator is currently pointing furthest, second furthest, third furthest, etc., towards its respective symbol 86 when the motion device 58, e.g., the stepper motor stops moving. In an embodiment, a random generation device stored in the memory device 40 generates the outcome randomly for the player before the motion producing device 58 begins to move. The displays run a sequence that is fun and exciting for the player and which indicate over time each of the various different symbols 86. The sequence ends with the randomly generated symbol being indicated.
In each of the cam driven embodiments described herein, the processor 38 knows, based on the position of the cam, i.e., the position of a motor shaft, which indicator is currently in the “indicating” i.e., award yielding, position with respect to its associated symbol. The stepper motors in an embodiment operate in an open loop system, wherein the processor relies on the fact that the stepper motor actually moves or rotates the amount commanded by a number of steps sent as a high-level communication from the processor 38 to the motion controller 56 and then as motor current outputs from the motion controller 56 to the motion producing device 58.
In an alternative embodiment, the processor 38 operates in a closed loop environment. Here, the stepper motor can include or provide encoder feedback, which senses the rotational position of the motor shaft with respect to a reference such as zero degrees. The encoder feeds this information back into the processor, so that the processor 38 does not have to rely on the motor actually doing what it is told to do. The encoder feedback can also be used by the processor 38 to compensate for errors in the system. That is, if the processor 38 learns that the motor shaft has not turned to the proper position, processor 38 can calculate and send a command of a number of steps or pulses needed to turn the stepper motor shaft to the proper position.
Gaming device 10 provides, in various embodiments, other types of feedback to the processor 38 other than encoder feedback. For example, one or more sensors, such as magnetic sensors, capacitive sensors, proximity sensors, light-emitting and receiving sensors, etc., can be placed at various points on the displays to sense the presence of a designated portion of the cam or one or more of the indicators. The sensed position provides feedback to the processor 38, so that the processor 38 knows that the arrangement of indicators is in a particular configuration. The sensors can also be placed on the inside or outside of the panel of the upper display area 32 and sense various different components, such as the connectors that hold the indicators within the slots 88. The connectors provide a convenient place that is out-of-sight and which also indicates accurately the position of the indicators.

For each indicator 462 to 476, the motion producing device 58 is connected, for example by a motor coupler 492, to a lead screw 494. The motor couplers 492 can each have spring portions that compensate for misalignment between the motion producing devices 58 and the lead screw 494. The lead screw in an embodiment is steel or stainless steel and is rotated by the motion producing device 58. The opposite end of each lead screw 494 from the motor coupler 492 is connected to a bearing 496. The bearings 496 mount to the panel of the upper display area 32 or to a structural member of same.
When the motion producing devices 58 turn, the lead screws 494 turn to move connectors 498 threaded onto each lead screw 494. If the lead screw is turned in one direction, connector 498 moves linearly and radially in a first direction along lead screw 490. If the lead screw 494 is turned in the opposite direction, connector 498 moves in the opposite direction along the lead screw 494 in a radial, translational direction.
The connectors 498 attach to the indicators 462 through 484 through the slots 88 in the panel of the upper display area 32 via co-connections not illustrated in
The display 460 provides a highly entertaining three-dimensional visual display that also has a functional component. For example, in the illustrated embodiment of
Referring now to
A separate motion producing device 58 or stepper motor is provided for each indicator 462 to 476. In the illustrated embodiment, each of the rotational motion producing devices are attached via a suitable coupler or other attachment device to a lead screw or linear actuator 494, which attaches at the other end to a bearing 496. Each lead screw or linear actuator 494 drives a connector 498. Each connector 498 is slidingly attached to a metal or plastic guide 502. The guide 502 is mounted to the panel of the upper display area 32 (not illustrated) or a structural member thereof. The guide 502 aids the connector 498 in moving radially and translationally within a slot 88 (not illustrated) in the panel. A portion 504 of the connector 498 extends through the slot 88 and is attached to the respective indicator 462 to 476. The portion 504 is formed integrally with or is attached to the remainder of the connector 498. As illustrated, the portion 504 is structurally rigid and strong and at the same time thin so as to be slideable within the respective groove 88.
It should thus be appreciated that the present invention provides wagering gaming devices including one or more flexible indicators which are extendable and retractable to indicate symbols such as award or credit symbols. It should further be appreciated that the flexible indicators can move simultaneously, sequentially, and in any suited positions from fully extended to fully retracted. Further, in alternative embodiments of the present invention, the symbols could indicate any suitable game function, triggering event or game events such as an award of credits, a modifier such as a multiplier, a number of free games or spins, or a bonus or secondary game.
It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
