Definitions

  • This invention relates to gaming or amusement machines.
  • a gaming machine of the fruit-machine type one or more parallel rows of symbols are displayed to a player through a viewing window.
  • These symbols are commonly pictures of fruit or playing cards, but may take any form.
  • Each symbol in a row is one of a succession of picture symbols inscribed on the narrow cylindrical surface of a drum.
  • the disc When the disc is caused to rotate, usually by the insertion of a coin and the operation of a push button or lever, the player sees the pictures moving through the viewing window until the disc comes to rest and new stationary pictures are displayed.
  • three rotating discs may be used to show three parallel rows of three symbols through the viewing window.
  • the player either wins or loses on the machine according to the symbols displayed in the window, that is to say according to the rotational position of the discs. It is required that the machine should automatically sense the rotational positions of the discs and to pay out or to give-some other benefit to the player if the combination is one of the winning combinations of positions.
  • the present invention provides:-
  • the series of surfaces is preferably a series of reflecting and non-reflecting surfaces. This series may be disposed in an annular band on a disc which either comprises said rotatable member.or rotates with the rotatable member.
  • the number of reflecting surfaces is preferably equal to the number of stop positions of the rotatable member, each reflecting surface thus being associated with a corresponding one of the indicia disposed on the rotatable member.
  • the indicia are carried on the peripheral cylindrical surfaces of rotating drums or reels.
  • a respective further disc 1 is co-axially mounted with each of the indicia-bearing members for rotation therewith.
  • Each further disc 1 is used to provide stopping means to arrest rotation of the associated rotating drum or reel and to provide means for sensing the angular position of the drum or reel.
  • the disc 1 has a number of circumferentially spaced teeth..2. These teeth are provided with slopes 3 on their trailing edges. Each.tooth corresponds to a particular picture symbol on the associated rotating disc or drum. The disc 1 is stopped when a latch is dropped into one of the slots between the teeth and the trailing edge slope ensures that the latch slips easily into the slot.
  • a ring 4 of alternate black and white surfaces is printed on the face of the disc coaxial with the disc.
  • Each white surface is located beneath a corresponding tooth 2 and is longer than each black surface.
  • a rectangular support plate-5 is mounted adjacent the disc 1 and separated from it by a narrow gap.
  • the support plate 5 is positioned so that it overlaps the ring 4 of black and white surfaces.
  • the plate 5 supports a light source 6 and a photoelectric receiver 7, between the plate and the disc 1.
  • the source.6 and receiver 7 are so angled that light from the source is incident on the ring 4, and if reflected, returns to the receiver 7.
  • the disc 1 rotates, light from the source 6 is successively incident on the black and white surfaces of the ring 4.
  • the reflected radiation from a white surface passing the sensor. is sufficient for the receiver 7 to produce an electric pulse whilst the light reflected from a black surface is not.
  • the receiver 7 produces a series of electrical pulses. These pulses are counted by an electronic counter connected to the receiver 7 and the rotational position of the disc can hence be computed.
  • two source/sensor units 10, 11 are provided for each rotating disc 1..
  • the source/sensor units are closely spaced on the support plate 5 their spacing being less than one quarter of the extent of a white surface in the ring 4.
  • the two sensor units 10 and 11 function independently and either may provide the count pulses. However, the pulse transitions in the output signals from these sensors are displaced in time.
  • a transition from a white to a black space on the ring 4 opposite the sensors is detected first by sensor 10 then by sensor 11. This is reversed when the disc rotates in the opposite direction. This difference is detected by the computing circuitry so that pulses occurring when the disc moves in reverse are not added to the count total but subtracted, thereby ensuring that the count total corresponds to the disc position in whichever direction it rotates.
  • a further light source and receiver may be provided which are located radially further inwards than the source and receiver 6 and 7, and a small reflecting area on the disc surface is also included which passes the further source and receiver onee per revolution to produce a corresponding electrical pulse from the receiver. This pulse is used by the computing circuitry to reset the counter. ;
  • the additional black surface method is used to reset the counter or if one black surface is given an extent greater than the others detecting this different length can be a problem at low rotational speeds.
  • the angular velocity may be continually monitored by measuring the length of the black/white and white/black conditions and the timing limits adjusted accordingly.
  • the next position of the disc is deduced without reference to the black pulse length. Thus if there are 22 display positions after counting 22, the next count is treated as 0 automatically.
  • annular band to provide the alternate reflecting and non-reflecting surfaces
  • the flat surfaces of the teeth 2 may be used as the reflecting surfaces and the gaps between them as the non-reflecting surfaces, it is preferable in this case to paint the surfaces of the teeth white to improve reflection.
  • the teeth on the disc may be painted black to provide the non-reflecting surfaces, while the reflecting surface is provided by a white or mirrored surface behind the disc on.which light is incident through the teeth.
  • the annular band may comprise successive areas of different magnetic permeability located in a magnetic field.
