[0001] This invention relates to a display device for a coin-operated machine for playing
a game. References to 'coin' are intended also to cover other means of supplying monetary
value.
[0002] Coin-operated gaming machines of the kind commonly referred to as 'fruit machines'
or 'slot machines' typically have symbol-bearing rotatable reels which rotate within
a machine cabinet and then come to rest with a selected combination of symbols displayed
through a window in the cabinet, a prize being paid out to the player in the event
that the selected combination is one of the winning combinations listed on a display
panel on the front of the cabinet.
[0003] With such machines there is a requirement to display to players a range of fixed
and changeable information concerning game-play operation of the machine. This can
be done by use of printing on the cabinet display panel in combination with controlled
back illumination and also by use of incorporated video screens and alphanumeric digital
display devices.
[0004] However known such information display devices can lack versatility and/or player
appeal.
[0005] An object of the present invention is to provide an improved display device capable
of enhanced versatility and player appeal.
[0006] According to the invention therefore there is provided a coin-operated machine for
playing games, said machine having a cabinet housing, an operating system, and a display
device connected to and controlled by the operating system for displaying information
relating to games, wherein the display device comprises a unit external to the cabinet
having a digital display screen which is movable repeatedly across a display region
of the unit.
[0007] With this arrangement, by appropriate control of the digital display screen it is
possible to display a range of game-play information, and the movement of the screen
can produce an interesting prominent display of the game-play information.
[0008] Accordingly, the display device can provide a versatile and appealing means of displaying
game-play information.
[0009] The screen may be movable repeatedly across the display region by motion backwards
and forwards or around a closed path. In a preferred embodiment the screen rotates
through a closed circular path, particularly about an upright axis.
[0010] Preferably the screen is movable with sufficient speed to give persistence of vision
i.e. such that information displayed on the moving screen appears to be static.
[0011] Movement of the screen may be effected by means of an electric motor or any other
suitable device.
[0012] The screen may be of any suitable shape. In a particularly preferred embodiment it
is spherically curved and preferably it is rotatable about its centre of curvature,
or about an axis through such centre of curvature, so as to move through a spherical
or part spherical display region.
[0013] The display screen may be an LED or LCD or similar screen.
[0014] The display device unit preferably includes a transparent panel or enclosure behind
which the screen moves. Especially in the case of spherical or part spherical movement
this may comprise a transparent spherical dome.
[0015] The unit may be fixed on top of the game machine cabinet or may be mounted in relation
to the cabinet or separately therefrom in any other suitable manner.
[0016] The machine may be of the fruit machine or slot machine kind having reels, as described
above, although the machine may alternatively be of any other suitable kind.
[0017] The information displayed with the display device may be of any suitable nature and
thus may consist of any one or more of: details of game-play winning outcomes, such
as a chart or list of symbol combinations which result in wins; details of special
wins such as jackpots, bonuses, etc; information concerning current status of game-play,
such as value of game-play credit, value of accumulated prizes, available special
game play features, outcome of the current games; machine advertising or notification
information, such as the name of the machine, etc.
[0018] The displayed information may change so that different kinds of information can be
displayed on different occasions or at different stages in game-play.
[0019] The invention will now be described further by way of example only and with reference
to the accompanying drawings in which:-
- Figure 1
- is a diagrammatic front elevation of one form of a machine according to the invention;
and
- Figure 2
- is a diagrammatic representation of the control system of the machine.
[0020] Referring to Figure 1 this shows a game machine having a cabinet 1 with upper, middle
and lower front panels, 2, 3, 4 and a row of push buttons 5 on a forwardly projecting
surface between the middle and lower panels 3, 4.
[0021] In one upper corner of the middle panel 3 there is a coin slot 6 and beneath the
lower panel 4 there is a pay-out opening 7.
[0022] Within the middle panel 3 there is a window 8 through which can be seen three side-by-side
reels 9 mounted for independent rotation about a common horizontal axis within the
cabinet!
[0023] Within the cabinet 1 motors 10 for driving the reels 9, a coin mechanism 11 to receive
coins from the slot 6, and a pay-out mechanism 12 to deliver awarded prize coins to
the payout opening 7, are connected to a microprocessor control device 13 of the machine
operating system.
[0024] The panels 2, 3, 4 are light-transmitting printed glass panels which have regions
which can be selectively back illuminated with lamps 14 which are also connected to
the control device 13.
[0025] On the top of the cabinet 1 there is mounted a display unit 15 which comprises a
transparent plastics spherical dome 16 fixed to a support base 17 which is fixed to
the top of the cabinet 1.
[0026] This dome 16 contains an electric motor 18 fixed within the base 17 and projecting
upwardly therefrom with a spindle 19 extending vertically from the top of the motor
into the dome terminating in the vicinity of the spherical centre of the dome 16.
[0027] Attached to the end of the spindle 19 is a rotor arm 20 which extends horizontally
and radially from the centre of the dome. At its outer end the arm 20 supports a curved
screen 21. This screen 21 is located very close to, but spaced from the inner surface
of the dome 16. The curvature of the screen 21 is spherical and substantially the
same as that of the dome 16. The dimensions of the screen 21 are such that it covers
a minor proportion of the surface of the dome.
[0028] The screen 21 comprises an LED matrix and the LEDs are connected to a connector 22
in the support base 17 via an appropriate commutator or similar device at the spindle
19.
[0029] The display unit 15 so far described may be a proprietary iBall sold by Spacewriter
Ltd.
[0030] The connector 22 within the support base 17 is connected to the control unit 13 of
the operating system, as also is the motor 18.
[0031] In use, the motor 18 rotates the screen 21 about a vertical axis. Static and also
animated alphanumeric information and graphics can be produced on the screen 21 by
appropriate actuation of individual LEDs and the resulting display can be seen clearly
from any viewing position around the ball. The speed of rotation of the screen 21
is fast enough to cause the display to be viewed at a fixed position (i.e. not rotating
around the ball) due to persistence of vision.
[0032] The nature of the display is controlled by the operating system and relates to games
played on the machine.
[0033] In conventional manner, the machine operates to play a game after sufficient game-playing
monetary value has been credited by insertion of coins through the coin slot 6.
[0034] Game play commences by pressing a start button 5 and the reels 9 then rotate and
come to rest after different respective random periods of time. Symbols on the peripheries
of the reels 9 are then displayed to the player through the window 8 on a central
horizontal win line. There may be three or four reels 9 so that three or four symbols
are shown on the win line. There may also be two symbols shown in the window 8 above
and below the win line for each reel.
[0035] The resulting combination of symbols on the central win line and/or on other win
lines is assessed against a table of predetermined winning combinations (which may
be printed on the upper panel 2) and a payout is made available to the player, and
can be obtained by pressing a collect button 5, if the resulting combination is a
winning combination.
[0036] In accordance with conventional practice, there may be special winning combinations,
such as a jackpot combination, there may be special game features such as surprise
awards etc., and provision may be made for the player to seek to influence the symbol
combination by using nudge or hold buttons 5 or the like.
[0037] The display unit 15 displays information relating to game play for example as follows:
prior to, or at selected occasions during game play decorative and/or attract information
may be displayed e.g. showing the name of the machine, the value of attainable jackpot
awards, etc.
during play, information concerning current status or game features may be displayed,
such as value of game-play credit, value of awarded prizes available for payout, win
or lose game outcome, current availability of game features.
during play, information relating to game-play directions may be displayed, such as
'press start now' etc.
during play, game play displays may be replicated e.g. such that symbols on the reels
may also be shown on the LED screen, etc.
[0038] The display unit 15 may be arranged to display any one or more or all of this information
on any fixed or changing basis of a predetermined or regular, or random or other basis.
[0039] With this arrangement there is provided an attractive and prominent means for displaying
information to the player and also to other persons nearby. This enhances machine
appeal and also availability of information.
[0040] It is of course to be understood that the invention is not intended to be restricted
to the details of the above embodiment which are described by way of example only.
[0041] Thus, for example, instead of the screen 21 which itself bodily moves over the viewing
region (i.e. the surface of the dome 19) it may be possible to use a bodily movable
screen which covers the viewing region via projection, or to use a screen which does
not bodily move but which has parts which are actuable in sequence so that the sequence
of actuation moves.
[0042] Also whilst reference has been made by way of example to the iBall product of Spacewriter
Ltd, other display devices can also be used such as the Magic Ball of Spectra Displays
Ltd.
[0043] The display device provides a display which moves repeatedly across a display region,
preferably which rotates through a circular path about a fixed or movable vertical
or inclined axis particularly to cover a spherical or part spherical display region.
