BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] This invention relates to a gaming machine such as a pinball machine or a slot machine
and in particular to a gaming machine for simulating rotation drums, normally three
rotation drums, disposed in a row on a display.
2. Description of the Related Art
[0002] Such a gaming machine will be discussed with reference to Figure 3 by taking a pinball
machine of the currently main stream type as an example.
[0003] In Figure 3, a display section 100 is provided to carry out simulated display of
the operation of rotation drums on subdisplay sections 101 to 103 into which one screen
of a flat display device such as a liquid crystal display or a plasma display is divided
for convenience.
[0004] When a player grasps a propelling dial 107 with his or her right hand and turns it
at a desired angle against an elastic force of the propelling dial 107, pinballs stored
in a pinball return 110 are propelled intermittently at a rate of several pinballs
per second at the strength responsive to the turn angle of the propelling dial 107
by an electric pinball propelling device (not shown). The pinball 122 advances in
the direction of an arrow 121 along a guide rail 108 and is discharged in the direction
of an arrow 123 at the top end of the guide rail 108 and led to the top of a base
board 109.
[0005] A large number of obstacle nails 125 (some are shown in the figure) are provided
on the base board 109 in addition to the subdisplay sections 101-103, a special win
hole 105, and a bumper win hole 106. The pinball hall can delicately adjust the inclination
of the obstacle nails 125 for changing the ease with which pinballs enter the special
win hole 105.
[0006] Other win holes can be provided in addition to the special win hole 105 and the bumper
win hole 106. The term "win" in this specification is used to mean a state in which
a pinball 122 enters a win hole, which is a predetermined hole or opening in the base
board other than an out hole 111. At the time of win, a predetermined number of pinballs,
for example seven pinballs, are paid out to the pinball return 110 from a pinball
dispensing mechanism (not shown) normally provided on the rear of the base board 109.
When a certain quantity or more of pinballs are stored in the pinball return 110,
the excessive pinballs automatically fall into a lower pinball return 112 through
an internal passing mechanism (not shown). When the lower pinball return 112 also
fills with pinballs, the pinballs are shifted manually to a box provided outside the
gaming machine.
[0007] Two or more special win holes 105 may be provided. The bumper win hole 106 is formed
with a plate-like rectangular lid that can be opened forward of the base board with
the lower side as a hinge shaft. Normally, it is closed; it is opened only under special
circumstances, allowing a number of pinballs to enter at a time, as described below.
[0008] Particularly, when a pinball enters the special win hole 105, each of the subdisplay
sections 101-103 carries out a rotation display of a number of prepared symbols, for
example 16 symbols, as symbols rotate on a slot machine, and stops the rotation display
of the symbols in sequence under the control of an internal processor for still display
of any of the symbols on the front. The term "rotation" or "rotation display" in this
specification is used to mean simulation, on a display screen, of a state in which
a plurality of symbols represented on the outer peripheral surface of each of three
rotation bodies placed in a row rotate in a slot machine for displaying the symbols
in a circulating manner.
[0009] If a pinball enters the special win hole 105 while the subdisplay sections 101-103
are carried out rotation display, it is guaranteed that after the rotation display
stops, rotation is again started up to a predetermined number of pinballs. In other
words, the right of rerotation is saved. In the example shown in Figure 3, the predetermined
number is four; up to four pinballs entering the special win hole 105 are indicated
on four lamps in a number-of-wins display section 104. When some lamps in the number-of-wins
display section 104 are on, if rotation display of symbols in all three subdisplay
sections 101-103 stops, one lamp goes off. That is, the saving count is decremented
by one.
[0010] In a case, when the subdisplay sections 101-103 stop rotation display, all three
display symbols displayed in the subdisplay match, the bumper win hole 106 opens and
allows pinballs to enter the bumper win hole 106. When a predetermined number of pinballs,
for example 10 pinballs, enter the bumper win hole 106 or a predetermined time, such
as 30 seconds, has elapsed, the bumper win hole 106 is closed. An event in which three
symbols displayed in the subdisplay sections 101-103 match is called a "jackpot" and
the time interval between the instant at which the bumper win hole 106 first opens
and the instant at which it is closed is called a "round."
[0011] Generally, most gaming machines of this kind provide a number of successive rounds,
for example, 16 rounds for one jackpot. Some models are adapted to allow a player
to advance to another round only if a pinball enters a specific part in the bumper
win hole 106 in one round.
[0012] Generally, in pinball machines of this kind, the subdisplay sections 101-103 stop
rotation of symbols in order. Of course, only after two symbols displayed in the subdisplay
sections 101 and 102 match, there is a possibility that all three symbols displayed
in the subdisplay sections 101-103 will match. Thus, an event in which two symbols
displayed in the subdisplay sections 101 and 102 match is called a "possible jackpot."
[0013] The most popular method of providing the subdisplay sections 101-103 is by a flat
display such as a liquid crystal display or a plasma display.
[0014] Pinballs not entering any win holes fall into the out hole and are collected by the
pinball hall.
[0015] In the pinball hall, a player receives as many pinballs as correspond to the cash
which he or she pays at the time of game play start, and can gain a prize according
to the number of pinballs that the player has with him or her at the time of game
play end. How the player gains a large number of pinballs, namely, causes a large
number of pinballs to enter into the special win hole for raising the possibility
of a jackpot is the point of playing the a game.
[0016] By the way, when a jackpot occurs, the subdisplay sections 101-103 blink display
of the still symbols corresponding to the jackpot. That is, the jackpot continues
for several minutes, during which display in the display section is dull, which is
less visually appealing.
SUMMARY OF THE INVENTION
[0017] It is therefore an object of the invention to provide a gaming machine for displaying
in a new display section so that the visual appeal is raised and the player's excitement
is increased when a jackpot occurs.
[0018] To this end, according to the invention, there is provided a gaming machine comprising
a display device having at least three subdisplay areas into which one display area
is divided, the subdisplay areas being arranged in a row, a still picture source for
providing a plurality of symbols to be selectively displayed in each of the subdisplay

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0022] Referring now to the accompanying drawings, there is shown a preferred embodiment
of the invention.
[0023] In Figure 1, a gaming machine 10 according to the embodiment of the invention has
a moving picture source 11 for storing moving picture information displayed when a
jackpot occurs, a still picture source 13 for storing still symbols for normal rotation
display, display control means 20 for receiving their outputs 12 and 14, and display
means 22 for carrying out rotation display of still pictures or displaying moving
pictures under the control of the display control means 20. Still picture data 20a
and moving picture data 20b from the display control means 20 are indicated by different
signal lines, but may be transmitted on a single signal line, as is shown in Fig.
2.
[0024] In the embodiment, nonvolatile recording media, such as CD-ROM, magnetic disk, and
nonvolatile semiconductor memory, can be used as the moving picture source 11 and
the stiil picture source 12.
[0025] In the embodiment, the display control means 20 is provided by electronic circuitry
using a microprocessor. An image processor containing an image compression/enlargement
function, etc., may be used together with the microprocessor. Specific processing
contents of the display control means 20 will be discussed later.
[0026] The display means 22 is a display device such as a liquid crystal display, an EL
display, or a CRT, but preferably it is a flat color display device such as a color
liquid crystal display.
[0027] As with the conventional pinball machine described above, in the embodiment, shown
in Fig.3, after a bumper win hole 106 has opened, it is closed when a predetermined
number of pinballs, for example 10 pinballs, enter the hole or a predetermined time,
such as 30 seconds, elapses . A predetermined number of pinballs, for example, 15
pinballs are paid out to a pinball return 110 for each of the pinballs entering the
bumper win hole 106 during the time interval between the instant at which the bumper
win hole 106 opens and the instant at which it is closed, namely, in one round. Therefore,
once a jackpot occurs, a large quantity of pinballs are output in a short time.
[0028] Next, a control section for carrying out the operation of the embodiment will be
discussed.
[0029] A control section 300 shown in Figure 4, which corresponds to the display control
means 20 in Figure 1, is located inside the pinball machine and controls the pinball
machine for carrying out the operation of the embodiment described above.
[0030] In Figure 4, the control section 300 has a display controller 401, a special win
section control 404, a number-of-wins display section control 405, a bumper win section
control 406, and a memory 409 under the control of a microprocessor 408. It further
includes an I/O control 407 for controlling reading of the moving picture source 11
and a still picture source 12. The display controller 401 controls the display section
100 for carrying out display or rotation display of still picture symbols from the
still picture source 12 in the subdisplay sections 101-103 or displaying a moving
picture from the moving picture source 11 in the entire display area of the display
section 100. The memory 409 is an internal memory for storing a program executed by
the microprocessor 408 and various items of data, which will be described with reference
to Figure 5, used by the program.
[0031] The special win section control 404 receives a signal from a special win section
205 for detecting a pinball entering a special win hole 105 and informs the microprocessor
408 of the event. That is, whenever the special win section control 404 detects a
pinball entering the special win hole 105, it adds 1 to the count of a special win
counter provided inside the special win section control 404. The special win counter
is a counter that can count from 0 to 3; the count value is output to the number-of-wins
display section control 405.
[0032] The number-of-wins display section control 405 controls the turning on/off of four
lamps provided in the number-of-wins display section 104. That is, it is adapted to
display the number of pinballs entering the special win hole 105 (a maximum of four)
in the number-of-wins display section 104 based on the count output from the special
win section control 404. To do this, the number-of-wins display section control 405
can turn on as many lamps as the count. The bumper win section control 406 controls
the bumper win section 206 so as to open or close the bumper win hole 106, under the
control of the microprocessor 408. Whenever the bumper win section control 406 detects
a pinball entering the bumper win hole 106 while the bumper win hole 106 opens, it
informs the microprocessor 408 of the event.
[0033] The microprocessor 408 reads the program stored in the memory 409 and executes it
for carrying out the operation of the embodiment. The counter function of the control
section 404 can also be provided in software by executing the program.
[0034] Figure 5 is an illustration showing various items of data stored in the memory 409.
[0035] In Figure 5, numerals 501 and 502 are display symbol storage areas for storing the
symbols displayed in the subdisplay sections 101 and 102 when rotation display of
the subdisplay sections 101 and 102 stops. Numeral 504 is a bumper win counter for
counting the number of pinballs entering the bumper win hole 106 up to ten. Numeral
505 is a symbol group storage area for storing a still picture symbol group selected
out of the still picture source 12. This symbol group becomes a symbol group placed
on the outer peripheral surface of each rotation drum.
[0036] Figure 6 is a flowchart showing an operation flow of the special win section control
404 and the number-of-wins display section control 405.
[0037] Whenever the special win section control 404 detects a pinball entering the special
win hole 105 at step 601, it adds 1 to the count of the special win counter provided
inside the special win section control 404 at step 602. The count of the special win
counter is output to the number-of-wins display section control 405, which turns on
as many lamps provided in the number-of-wins display section 104 as the count at step
603. The operation shown in Figure 6 is always performed independently of the operation
of the microprocessor 408 described below. The process can also be executed by program
processing of the microprocessor 408. In this case, a special win counter area is
provided in a memory and processing is performed concurrently with another processing
described below in a time-division manner.
[0038] Figures 7 and 8 are flowcharts showing operation flows of the microprocessor 408.
[0039] Figure 7 shows a symbol display process in the subdisplay sections 101, 102, and
103 executed by the microprocessor 408. When the pinball machine power is turned on
or a propelling dial is turned, the symbol display process is started.
[0040] As shown in Figure 7, in the symbol display process, the microprocessor 408 first
takes out a still picture group from the still picture source 12 and stores it in
the symbol group storage area 505 at step 700. The symbol group may be predetermined.
It can also be selected, for example, at random from among symbols stored in the still
picture source 12 each time the process is started. Figure 2 shows a state in which
pictures of human figures are adopted as a symbol group and different human figures
are displayed on the rotation drums 101-103. However, pictures or symbols are not
limited to human figures and may be anything.
[0041] Next, the microprocessor 408 determines the count of the special win counter in the
special win section control 404, and if the count is not 0 at step 701, it outputs
an operation start signal to the display controller 401 for starting the operation
of the subdisplay sections (rotation drums) 101-103 at step 702 and subtracts one
from the count of the special win counter at step 703, whereby the display controller
401 starts the operation of the subdisplay sections 101-103.
[0042] Subsequently, when a predetermined time or the time found by random number calculation
has elapsed, the microprocessor 408 outputs an operation stop signal to the display
controller 401 for stopping the operation of the subdisplay section 101 at step 704.
The display controller 401 then stops rotation display of the subdisplay section 101
and outputs the symbol displayed when the rotation display of the subdisplay section
101 stops to the microprocessor 408, which then stores the display symbol output from
the display controller 401 in the display symbol storage area 501 of the memory 409
at step 705.
[0043] Likewise, when a predetermined time or the time found by random number calculation
has elapsed, the microprocessor 408 outputs an operation stop signal to the display
controller 401 for stopping rotation display of the subdisplay section 102 at step
706 and stores the display symbol output from the display controller 401 in the display
symbol storage area 502 of the memory 409 at step 707.
[0044] Subsequently, when a predetermined time or the time found by random number calculation
has elapsed, the microprocessor 408 outputs an operation stop signal to the display
controller 401 for stopping the operation of the subdisplay section 103 at step 708.
When rotation display of the subdisplay section 103 stops, the microprocessor 408
compares the symbol displayed at the time with other two symbols previously stored
in the areas 501 and 502 at step 709. If they do not match, the microprocessor 408
deletes the display symbols stored in the display symbol storage areas 501 and 502
at step 710 and returns to step 701.
[0045] On the other hand, if the three display symbols match at step 709, the microprocessor
408 performs a jackpot process (shown in Figure 8) at step 711. After the jackpot
process ends, the microprocessor 408 goes to step 710. Figure 2 (b) shows a state
in which all human figure pictures displayed on the rotation drums (three subdisplay
areas) which stop match.
[0046] As shown in Figure 8, in the jackpot process, the microprocessor 408 first changes
the display of the display section 100 to display of a moving picture from the moving
picture source 11 at step 801, whereby the moving picture is displayed in the entire
area of the display section 100 as shown in Figure 2 (c). In the embodiment, a different
moving picture can be displayed for each round. The fact that the current round is
round 1 is indicated on the background of the moving picture shown in the figure.
[0047] Next, the microprocessor 408 outputs an open signal to the bumper win section control
406 for opening the bumper win hole 106 at step 802, whereby the bumper win section
control 406 opens the bumper win hole 106, allowing pinballs to enter the bumper win
hole 106. Each time the bumper win section control 406 detects a pinball entering
the bumper win hole 106 while the bumper win hole 106 is open, it outputs a win detection
signal indicating the event to the microprocessor 408, as described above.
[0048] When the win detection signal is output from the bumper win section control 406 at
step 804 by the time a predetermined time, such as 30 seconds, has elapsed at step
803 after jackpot rounds were entered, the microprocessor 408 adds one to the count
of the bumper win counter 504 at step 805.
[0049] If the count of the bumper win counter 504 does not reach 10 at step 806 as a result
of adding one to the count of the bumper win counter 504, the microprocessor 408 returns
to step 803. If the count reaches 10, the microprocessor 408 goes to step 807. When
the predetermined time (in this case, 30 seconds) has elapsed at step 803 regardless
of the count of the bumper win counter 504, the microprocessor 408 also goes to step
807.
[0050] At step 807, the microprocessor 408 outputs a closing signal to the bumper win section
control 406 for closing the bumper win hole 106, whereby the bumper win section control
406 closes the bumper win hole 106, disabling pinballs from entering the bumper win
hole 106. At the same time, the microprocessor 408 resets the value of the bumper
win counter 504.
[0051] If the microprocessor 408 determines that all rounds end at step 808, it restores
the display of the display section 100 to still picture display at step 809 and ends
the process. If not all rounds end, the microprocessor 408 returns to step 801, performs
moving picture display in the next round, and repeats the process until all rounds
end.
[0052] The pinball machine of the embodiment can also be adopted to allow another round
only if a pinball enters a specific part of the bumper win hole 106 in one round.
[0053] A pinball dispensing mechanism is provided to dispense pinballs in response to pinballs
entering the special win hole 105 or the bumper win hole 106. A win detection signal
indicating that a pinball has entered the special win hole 105 is output to the pinball
dispensing mechanism from the special win section control 404 and a win detection
signal indicating that a pinball has entered the bumper win hole 106 is output to
the pinball dispensing mechanism from the bumper win section control 406. When the
win detection signal is output from the special win section control 404, the pinball
dispensing mechanism dispenses, for example, seven pinballs to a pinball return 110.
When the win detection signal is output from the bumper win section control 406, the
pinball dispensing mechanism dispenses, for example, 15 pinballs to the pinball return
110. The pinball dispensing mechanism can be provided as follows: For example, a supply
passage where pinballs are arranged in a row for supplying pinballs to each pinball
machine from the pinball hall is normally shut off and when the control signal is
output from the microprocessor 408, the supply passage is opened for supplying as
many pinballs as specified.
[0054] To produce sound effects, a sound effect output mechanism is provided (not shown)
for outputting normal sound effects, possible jackpot sound, and jackpot sound effects.
A win detection signal is output from the special win section control 404 to the sound
effect output mechanism and a win detection signal is output from the bumper win section
control 406 to the sound effect output mechanism. Preferably, voice data is contained
in the moving picture source 11. When a moving picture is displayed, a voice corresponding
to the moving picture is output.
[0055] In the description, the display section 100 displays three symbols on only one horizontal
line. However, three symbols can be displayed on each of two or more horizontal lines
and a match among the three symbols on each line can be detected. When a match on
any line is detected, a jackpot can also be applied. To adopt three horizontal lines,
a symbol match on a diagonal line of 3 x 3 symbols can also be detected.
[0056] In the description, a moving picture is displayed only when a jackpot occurs. However,
a moving picture may also be displayed while the effective number of wins in the special
win section 205 is 0, and when the effective number of wins becomes one or more, the
display may be changed to rotation display of a still picture.
