Definitions

  • This invention relates to an amusement machine, in particular to a coin operated amusement machine.
  • a coin projection device comprising a coin entry which leads to a coin validation unit, coins validated by the coin validation unit passing to a coin stack holder, coin ejection means being provided for pushing the bottom coin in the stack onto a coin projection runway, the machine further comprising a firing mechanism for striking the edge of a coin on the runway to drive the coin along the runway thereby to project the coin.
  • This aspect of the invention thus enables a stack of validated coins to be formed, with individual coins being fed to a runway for projection onto a surface, such as a playfield constituting a part of an amusement machine.
  • the validation unit is provided with a first sensor for detecting whether a coin has been entered, and the runway is provided with a second sensor for detecting whether a coin is present on the runway, the coin ejection means being controlled automatically in dependence on the signals of the first and second sensors.
  • the feed of coins onto the runway by the ejection means is automated, so that the user simply controls the firing of the coins along the runway.
  • the ejection means may comprise a platform for supporting the coin stack, wherein the platform is slidable between a first position in which the coin stack is supported on the platform and a second position in which the coin stack is supported on a further, lower platform, and when the platform passes from the first position to the second position, the coin stack drops to the lower platform, and when the platform passes from the second position to the first position the lowest coin in the stack is pushed by the platform onto the coin projection runway.
  • This arrangement provides a simple structure for feeding individual coins to the runway.
  • the firing mechanism may comprise a hammer for striking an edge of the coin which overhangs the end of the runway, the hammer being drawn back manually against the action of a spring and being subsequently released to strike the coin.
  • the hammer can preferably be retained in one of a plurality of possible drawn back positions by a ratchet mechanism, the ratchet mechanism being released to release the hammer.
  • the invention also provides a coin-operated machine comprising a plurality of coin projection devices of the invention with a single manual control for drawing
  • the machine preferably has two coin projection devices.
  • the machine may be combined with a segmented playing surface to define an arcade-type game.
  • a coin magazine for a coin projection device comprising a coin holder for holding a stack of coins and a platform for supporting the coin stack, wherein the platform is slidable between a first position in which the coin stack is supported on the platform and a second position in which the coin stack is supported on a further, lower platform, and when the platform passes from the first position to the second position, the coin stack drops to the lower platform, and when the platform passes from the second position to the first position the lowest coin in the stack is pushed by the platform into a firing position.
  • This aspect of the invention also provides a means for enabling a stack of coins to be formed, wherein individual coins are fed onto a runway for projection.
  • an article holding apparatus including means for clearing articles therefrom, the apparatus comprising a surface for supporting an array of articles; at least one aperture in the surface through which articles can pass; and a sweeper arm in sliding contact with the surface, whereby relative movement between the surface and the sweeper arm causes the sweeper arm to sweep at least part of the surface, and the sweeper arm having at least one U- or V-shaped indentation in its leading surface relative to sweeping movement, the indentation having an apex which is located so as to pass directly over one or more of the apertures in the surface, whereby the relative movement between the sweeper arm and the surface causes articles on the surface to be swept both in the sweeping direction and transversely to the sweeping direction, towards the apex of the indentation, where the articles are held until the apex passes over an aperture, whereupon the articles pass through the aperture.
  • This aspect of the invention thus provides an effective method of clearing playing pieces, such as coins, on a moving surface such as a playfield constituting part of an amusement machine.
  • the term "coin” used herein is intended to include tokens and other similar articles.
  • the relative movement between the surface and the sweeper arm may be achieved by a combination of a movable playfield with a static sweeper arm, or a static playfield with a movable sweeper arm, or both the playfield and the sweeper arm may be movable.
  • the surface is comprised by a rotatable circular playfield, with at least two, preferably four, equally spaced radial sweeper arms.
  • an article holding apparatus comprises a surface defining a target field having an array of target areas at positions on the target field and a position encoder having a number of sensors, the target field and the or each sensor being adapted for relative movement to one another so that articles introduced onto the target field can be detected by a sensor, wherein the position encoder maintains a cyclical count and is arranged to determine whether or not an article detected by a sensor is within a target area on the target field with reference to a count value held by a counter.
  • This aspect of the invention provides an accurate way of determining the position of articles, such as coins or tokens, on target areas forming part of a playfield of an amusement machine such that a "win” occurs when a coin is detected on the target area.
  • Legal requirements dictate that wins must be properly recognised before a machine will be issued with the necessary gaming licence.
  • the position encoder comprises a microprocessor which maintains the count and has an associated memory device which stores a look-up table for mapping count values to target field position for use in determining whether or not an article detected by a sensor falls within one of the target areas on the target field.
  • the or each sensor is associated with at least one dedicated look-up table which defines the circumferential limits of each target area capable of passing within the detection field of the sensor with respect to count value.
  • the microprocessor is arranged to apply a correction factor when determining the position of an article on the target field with reference to a lookup table to compensate for any variation in the speed of the relative movement between the target field and the or each sensor over time.
  • the position encoder counter is reset periodically in dependence on the relative positions of the target field and the or each sensor.
  • the or each sensor is an inductive field-type sensor.
  • the relative movement between the surface and the or each sensor may be achieved by a combination of a movable playfield with one or more static sensors, or a static playfield with one or more movable sensors.
  • the playfield and the or each sensor may be movable.
  • the surface comprises a rotatable horizontal playfield with at least two radially spaced sensors.
  • an the amusement machine includes a horizontal playfield divided into four quadrants each with target areas which represent zones onto which a person must aim to project playing pieces, using a coin projection device in order to win.
  • Playing pieces such as coins or tokens may be used.
  • the win value is determined with respect to a stored set of game rules.
  • the playing pieces are then cleared using a fixed device (sweeper arm) which floats on the surface of the playfield.
  • the device catches the playing pieces and contains them until an aperture in the playfield passes under the device.
  • the playing pieces then fall through the aperture into a chute, and are delivered to a receptacle under the playfield.
  • the amusement machine also includes a position encoder which provides an accurate way of determining the positions of coins or tokens lying on the playfield, where legal requirements dictate that wins must be properly recognised before a machine will be issued with the necessary gaming licence.

  • Figure 1 shows an amusement machine 1 with a playfield 2 divided into four quadrants, each quadrant being provided with a coin projection device 3.
  • a player In use, a player must aim to project playing pieces onto the playfield using a coin projection device 3. Coins are cleared by a sweeper arm (see figure 2) and the position of the coins on the playfield are detected by a coin position encoder (see figure 2) to determine whether or not the player wins a payout in accordance with
  • Figure 2 shows a circular playfield 2 suitable for use in the machine of Figure 1 which rotates in the direction shown by the arrow A.
  • the playfield 2 has an array of marked target areas 3 , which form a part of the game associated with the amusement machine 1. In the course of the game, coins are projected onto the playfield 2. Some of the target areas have apertures 4 which are machined into the playfield. The target areas are spaced along four different circular tracks on the playfield.
  • a fixed metal chassis 5 is positioned above the playfield and divides the playfield into four equal quadrants.
  • the chassis 5 supports four equally spaced radial sweeper arms 6.
  • the chassis 5 floats immediately above the playfield by means of fixings in the centre and circumference of the playfield, thus allowing the
  • a sweeper arm 6 Fixed to each limb of the chassis is a sweeper arm 6 made of a machined block of self-lubricating material, such as oil filled nylon. As shown in Figure 3, this block is shaped to form four U- or V-shaped indentations 7 in the leading surface (with respect to relative movement between the playfield 2 and chassis 5). The indentations are positioned such that the apexes 8 pass directly over respective apertures 4 in the playfield. Thus, the apexes of the four indentations correspond respectively to the four circular tracks along which the target areas (and apertures) are positioned.
  • Each indentation has a shallow sloping side 9 closer to the centre of the playfield, and a steeper sloping side 10 further from the centre of the playfield. Together with the rotary movement of the playfield, this helps to direct the coins towards the apex.
  • Coins on the playfield are thus swept by the movement of the playfield into the indentations until they reach the apex, and the coins then fall through the apertures as the apex passes over the apertures.
  • Each circular track has one aperture in each of the four quadrants.
  • Coins on the playfield are thus cleared.
  • Sensors 11, such as inductive field-type sensors, are attached to the chassis 5 so as to sense coins and provide a signal to a game control system shown in Figure 4.
  • the apparatus includes an optical sensor 12 on one arm which is positioned to detect each of four equally circumferentially spaced marks 13 provided on the edge of the playfield 2 as they pass by the optical sensor 12 and output a signal to the control system shown in Figure 4.
  • the sweeper arm can be made of a metal casting, and provided with wheels on its surface adjacent the playfield surface. Provided the clearance between the two surfaces is small enough, coins can still be swept effectively, and the wheels reduce wear of the two surfaces.
  • the game control system shown in Figure 4 is centred around a microprocessor
  • the memory store 15 holds computer executable instructions for operating the amusement machine together with a number of look-up tables used in determining the position of the coin on the playfield, and in particular, whether or not a detected coin lies within one of the marked target areas.
  • Microprocessor 14 receives signals from each of the four induction sensors 11 provided on each of the four arms 6 of the chassis 5 together with signals from the optical sensor 12. The microprocessor 14 maintains an internal counter which is reset periodically in dependence on the output of the optical sensor 12.
  • the microprocessor 14 is also associated with a coin entry validation unit 16, a game display 17, and a payout dispensing unit 18.
  • coins which are projected onto a quadrant of the playfield 2 are detected by one of the sensors 11 on the respective arm 6 of the chassis 5.
  • the sensor outputs a logic low value and maintains this until the trailing edge of the coin passes outside the detection envelope.
  • the microprocessor 14 is arranged to detect the rising edge of the pulse generated by the sensor 11 and record the current count value held by the internal counter maintained by the microprocessor.
  • the microprocessor 14 accesses a look-up table held in the memory store 15 to check if the count value falls within the limits of one of the possible target areas on the circular band associated with the sensor. If it does, then a win is recorded, the value being determined with reference to the particular target area identified by the look-up table.
  • the playfield 2 is assumed to take a count of 3150 interrupts of the microprocessor clock cycle to rotate through 90° i.e. one complete quadrant. Whilst in some circumstances it may be acceptable to map the count value directly to the corresponding entry in the appropriate look-up table when a coin is detected, this is not the case when used in gaming machines, since variations in the rotational speed of the playfield (which is independent of the microprocessor interrupt cycle) can give rise to errors. In the present invention, these errors can be compensated for by applying a speed correction factor which takes into account the average rotational speed of the playfield 2.
  • the count maintained by the microprocessor 14 is only reset when the microprocessor detects an output from the optical sensor 12. Nariations in rotational speed mean that a count value may be less than or greater than 3150 at the time of reset. If the count value exceeds a predetermined maximum value (say 4000), the machine enters an alarm mode and the game stops.
  • a predetermined maximum value say 4000
  • a logic algorithm is applied by the microprocessor so that a win is detected when the following is satisfied:
  • count-value is the current count value on the playfield at the time the coin is detected
  • start bit and stop bit are values in the look-up table defining the circumferential limits of a winning target area identified in the look-up table with respect to the direction of rotation of the playfield
  • average count is the average number of counts taken to traverse each quadrant
  • 3150 is the length of the look-up table.
  • the present invention provides an accurate position encoder for determining the position of coins or tokens on the playfield. Indeed, the resolution at the innermost band of target areas is around 0.15 mm whilst the resolution at the outermost band of target areas only reduces to a figure of around 0.29 mm, each of which is sufficient to meet the requirements of the various gaming laws found Internationally.

  • the invention provides a coin projection device comprising a coin entry 19 which leads to a coin validation unit 20.
  • Coins validated by the coin validation unit are passed to a coin stack holder 21, coin ejection means being provided for pushing the bottom coin in the stack onto a coin projection runway.
  • the machine has a firing mechanism for striking a coin on the runway to drive the coin along the runway thereby to project the coin.
  • the machine shown in Figure 5 essentially comprises two functionally identical (but symmetrically inverted) coin projection devices as described above, arranged side-by-side, with a single manual control 25 for operating the two devices simultaneously.
  • the two devices are housed in a single housing comprising a top casing part 26 and a lower cradle 27.
  • the two devices illustrated in Figure 6 are shown exploded to different degrees, for the purposes of clarity.
