Description

  The present invention obtains a prize ball by dropping a game ball made of a magnetic material by its own weight along a game board surface provided with an obstacle, and winning a prize opening installed in the obstacle. It relates to gaming machines.

  Conventionally, in game machines, particularly pachinko machines, when a pachinko ball wins a winning prize opening, a lottery is executed internally for control, and a pattern variation pattern effect is produced by an image display device (LCD etc.) provided in an accessory. When the lottery result is notified and the winning of the lottery is notified, the special winning opening (which may be referred to as “attacker”) that is always closed in the normal gaming state is opened, and the gaming state is advantageous to the player (Hereinafter referred to as “special game state”).

  In the pachinko machine, the pachinko ball is steel, and there is a so-called “magnet goto”, which is a fraudulent act that guides the pachinko ball that falls by its own weight to the desired course by magnetic force (suction force) and wins the starting prize opening. For fraud, fraud is prevented by detecting the magnetic force by the magnetic sensor.

  According to Patent Document 1, when a magnetic body provided on a game board is attracted by a magnetic force, a contact point integrated with the magnetic body is attracted, so that a signal flows through the contact point in a conductive state, and an illegal action is notified. It has been proposed to do.

  The above fraud is based on the premise that a magnet with a magnetic force that can attract the magnetic material by the magnetic force is used. For example, if a magnet with a weak magnetic force is used at a position relatively far from the starting prize opening However, this cannot be detected.

  For example, for an obstacle that affects the pachinko ball guidance path called “windmill”, the rotation direction is limited by the magnetic force, making it easier to guide in the direction of the start winning opening. The effect of the magnetic sensor is not perfect for the act.

  A “magnetic material” is a substance that magnetizes when placed in a magnetic field. Although all materials have this property to some extent, a material that is particularly strongly magnetized and exhibits hysteresis is called a ferromagnetic material, and in the present invention, this ferromagnetic material is used.

Can be monitored.

  In the first invention, the magnetic sensor is limited to a sensitivity that does not detect magnetism generated from a component using a magnetic force applied to a game board.

  A game board may be attached with a motor, a solenoid, or the like, and needs to be a magnetic sensor having a sensitivity that does not detect magnetism generated from these.

  Further, in the first invention, when the game execution control means wins a game ball at the start port, a special symbol lottery is executed, and when the special symbol lottery is won, a lot of prize balls are given for a certain period of time. In a special gaming state that is advantageous to a player who receives the game, wherein the magnetic sensor is disposed in the vicinity of the start port, and the magnetic body constitutes a part of an obstacle on the game board surface. It arrange | positions in the position which makes a windmill vicinity the magnetic detection range, It is characterized by the above-mentioned.

  The magnetic sensor is in the vicinity of the starting port, and only the vicinity of the windmill far from the starting port can be set as the magnetic detection range.

  According to a second aspect of the present invention, a game ball made of a magnetic material is dropped by its own weight along a game board surface on which an obstacle is provided, and a prize ball is awarded to a winning opening installed along with the obstacle. A magnetic sensor that is attached to the game board and that is disposed opposite to the game board surface to detect magnetism emitted through a transparent plate provided to protect the game board; A storage unit that is provided in the game board and that can store a magnetic body that indirectly propagates the magnetism to a magnetic sensor for each of the areas of the game board divided into a plurality of areas in advance. Yes.

  According to the second invention, it is possible to pinpoint the target position of “magnet goto” detection by connecting the sensing areas of the magnetic sensor in a so-called rosary manner.

  As described above, the present invention has an excellent effect that the magnetic detection points on the game board can be intensively monitored by the magnetic sensor without increasing the sensitivity of the magnetic sensor.

The game board 100 shown in FIG. 2 and FIG. 3 has a resin sheet-like cell attached to a plywood board serving as a substrate, and the surface of the cell is a board surface. The outer rail 102 and the inner rail 104 are attached. In the circular area surrounded by the outer rail 102 and the inner rail 104, the game ball PB launched from the launching device (not shown) can be moved by its own weight fall, and this area plays a game. It is considered as a game area.

  Nails 128 and windmills 132 are scattered in the game area of the game board 100. In addition, a center accessory 105 is arranged almost in the center of the game area. The center accessory 105 includes a liquid crystal display (LCD) 106 that displays images such as various effects.

  A passing gate 118 having a normal symbol lottery starting function is arranged on the left side of the center accessory 105 in FIG.

  In addition, a start port (A) 130 and a start port (B) 134 are arranged in a column in the lower part of the center accessory 105.

  The upper part of the starting port (A) 130 is open so that the player can always win. On the other hand, the starting port (B) 134 closes the upper opening of the starting port (B).

  An electric tulip 136 is attached to the start port (B) 134. The electric tulip 136 is configured to open and close by energization / non-energization of a solenoid disposed on the back side of the game board 100.

  Here, when the electric tulip 136 is in an open state, the pachinko ball PB can be received in the winning opening, and the pachinko ball PB can be won.

  Further, as shown in FIGS. 2 and 3, an attacker 112 is disposed further below the start port (B) 134.

  The attacker 112 is provided with an opening / closing door 116. This open / close door 116 is opened or closed by energization / non-energization of the solenoid. That is, when the open / close door 116 is opened, the game ball PB dropped on the open / close door 116 is guided by the open / close door 116 and wins the attacker 112.

  In addition, an out-port 124 for discharging the dislodged ball to the back side of the game board 100 is provided at the lowest position of the game board 100.

  In addition, the center role 105 provided on the game board 100 and the peripheral edge of the board are provided with a number of light-emitting elements for lighting effects that are turned on, turned off, and blinking according to the progress of the game to produce a lighting effect. Yes.

  Here, the start opening (A) 130, the start opening (B) 134, and the attacker 112 are configured as one winning combination unit 200.

  Here, the winning combination unit 200 includes the start port (A) 130 and the start port (B) 134 that are integrally formed, and an attacker 112 that is provided separately from these.

  FIG. 4 is a perspective view of the game board 100 as seen from the back side. As shown in FIG. 4, the prize-winning accessory unit 200 is inserted into the through hole 100A provided in the game board 100 from the front side. It is fixed.

  The winning combination unit 200 protrudes on the back side of the game board 100, and a cover bracket 202 is attached to the periphery (left and right and bottom). Further, on the back side of the game board 100, a stage bracket 204 for holding a stage (not shown) is attached to the upper part of the winning combination unit 200 that is projected in the previous period.

  As a result, the periphery of the winning combination unit 200 protruding from the back side of the game board 100 is covered with the cover bracket 202 and the stage bracket 204 (see FIG. 5). Even if it is inserted, the winning combination unit 200 is not reached.

  By the way, winning in the winning combination unit 200, in particular, the starting port (A) 130 and the starting port (B) 134 is an important factor in the progress of the game. For this reason, the magnet 206 (see FIG. 5) is brought close to this area, and the game ball PB made of steel is attracted by a magnetic force, so that it becomes a target portion of a so-called “magnet goto” that illegally wins.

  Therefore, in the present embodiment, a magnetic sensor 208 is attached to the upper end portion of the cover bracket 202.

  The magnetic sensor 208 includes a reed switch having a pair of terminals formed of a magnetic material. When the reed switch terminals are attracted to each other by magnetic force, the reed switch becomes conduction information, and a signal flows through the circuit. This is a structure for switching output signals. For example, MS2B0603 manufactured by Union Electric Co., Ltd. is applicable.

  The greatest factor in selecting the magnetic sensor 208 is sensitivity. In the gaming board 100 according to the present embodiment, it is necessary to sense the magnetic field in the target area without being affected by the magnetic field from the parts using the magnetic force (motor, solenoid, speaker, LCD, etc.). It is necessary to use a magnetic sensor 208 having a high sensitivity and to arrange it at an appropriate position.

  FIG. 6 shows the sensitivity of the magnetic sensor 208 applied to this embodiment.

  This magnetic sensor 208 has the highest sensitivity (the detection area is wide) directly in front, and has a predetermined directivity (diffusivity of about 45 °).

  That is, by providing the upper end of the cover bracket 202, the start port (A) 130 and the start port (B) 134 can be included in the sensing area, and the start port (A) 130 and the start port (B). The magnetic force (magnet 206) approaching 134 is sensed, and the magnetic force of a solenoid (not shown) attached to the attacker 112 located obliquely forward and downward is not sensed.

  By the way, in recent years, there is a windmill 132 (see FIGS. 2 and 3) located at a position away from the start port (A) 130 and the start port (B) 134 as a target part of the new “magnet goto”. By approaching the windmill 132 with a magnet 206 having a weak magnetic force and restricting the rotation or rotation direction of the windmill 132, the game ball PB is indirectly guided to the start port (A) 130 and the start port (B) 134. It is.

  Therefore, in the present embodiment, the single magnetic sensor 208 is used to detect the magnetic force (magnet) approaching the windmill 132 at the remote position, and the stage bracket 204 is provided with an iron plate 210 made of a ferromagnetic material. Embedded. The iron plate 210 is disposed in the detection area of the magnetic sensor 208.

  By the way, the iron plate 210 itself initially has no magnetic force, but when the magnet 206 is brought close to the windmill 130, the magnetic field of the magnet 206 is applied to the iron plate 210, and the iron plate 210 generates a magnetic field. When the iron plate 210 generates a magnetic field, the magnetic sensor 208 detects this. That is, it is possible to detect the magnetic force (magnet 206) that the windmill 132 approaches indirectly.

  The operation of this embodiment will be described below.

  First, game control centering on lottery processing will be described.

  When the game ball PB wins the start opening (A) 130 or the start opening (B) 134, it is determined whether or not the start start winning is a valid start winning. The effective start winning means that the reserved balls are not full (for example, four), and that the game ball PB has won the start opening (A) 130 or the start opening (B) 134, and the lottery right is thereby obtained. Will get. In the invalid starting prize, the right to draw is not given, but a predetermined number (about 3 to 5) of prize balls may be paid out.

  If the starting prize is an effective starting prize, a random number is acquired, a pre-stored winning value is read, and both are compared to determine whether the lottery is winning or not.

  If the current gaming state is in jackpot processing or symbol variation pattern production, in order to put the right of the lottery on hold, the number of holdings is incremented by one (+1), and the current gaming state is in jackpot processing If there is no or even during the design variation pattern production, the lottery process is executed by subtracting the hold number by one.

  Based on the winning / losing of the lottery, the symbol variation pattern effect time is set, and a command including the lottery result and the symbol variation pattern time is sent to the lower control unit.

  The subordinate control unit notifies the lottery result using the set production time.

  After this notification, if the result of the lottery is a win, a jackpot process is executed. In the jackpot process, in the normal game state, the closed attacker 112 is always opened and closed by a predetermined number of rounds. The opening time of the attacker 112 is a maximum of 30 seconds. The attacker 112 is closed when a predetermined number (for example, 10) of game balls are won while the attacker 112 is opened, and after the predetermined closing time, The next round (open). Thereby, the player can receive a lot of prize balls in a short time.

  As described above, in the game specification according to the present embodiment, winning in the starting port (A) 130 or the starting port (B) 134 is a major premise in order to be a jackpot process.

  For this reason, the vicinity of the start port (A) 130 or the start port (B) 134 becomes a target portion of so-called “magnet goto”. That is, by bringing the magnet close to the game ball PB and attracting the game ball PB to the start port (A) 130 or the start port (B) 134 by magnetic force, more game balls PB are attracted to the start port (A) 130 or the start port (B). 134 is awarded.

  However, since the magnetic sensor 208 is attached to the back side of the start port (A) 130 or the start port (B) 134, when a magnet is brought close to the start port (A) 130 or the start port (B) 134, The magnetic sensor 208 detects this. For this reason, since prompt notification to the hall computer or the like is made, fraud is impossible.

  Further, in the present embodiment, an iron plate 210 that is a magnetic body is disposed in the sensing area of the magnetic sensor 208. The iron plate 210 itself is a magnetic material, but has no magnetic force.

  However, when a new “magnet goto” is generated that brings the magnet 206 close to the windmill 132 away from the start port (A) 130 or the start port (B) 134, the magnetic field of the magnet 206 affects the iron plate 210, and the iron plate 210 A magnetic field is generated from 210.

  As described above, the iron plate 210 in which the magnetic field is generated is present in the sensing area of the magnetic sensor 208, and thus detects the magnetic field of the magnet that approaches the windmill 132 at a pinpoint. Therefore, it is possible to detect the magnetic field generated by the magnet 206 approaching the windmill 132 located farther than the solenoid without being affected by the solenoid of the attacker 112 or the like.

  In this embodiment, the windmill 132 is used as a target for detecting “magnet goto” as a pinpoint. However, when the point at which the magnetic field is detected is determined on the game board 100, the arrangement position of the magnetic body is determined. Other than the windmill 132 can be pinpointed as targets for detecting “magnet goto”.

  In the present embodiment, iron 210 is used as the magnetic body, but the magnetic body is shaped in accordance with the target of “magnet goat” detection, as shown in FIGS. 7A to 7E, in addition to the iron plate. May be changed to have directivity.

  Furthermore, in this embodiment, iron 210 is used as the magnetic body. However, as shown in FIG. 8A, the magnetic body is a round bar 212 and the shape is changed according to the target of “magnet goto” detection. However, it may have directivity. Further, as shown in FIGS. 8B to 8F, the round bar 212 is bent or added to have directivity based on the target (magnetic field detection member), You may deform | transform into various shapes.

Further, as shown in FIGS. 8A to 8E, an iron plate Furthermore, the magnetic body is not limited to iron, but may be cobalt, nickel, or an alloy containing these.

  Further, in the present embodiment, the iron plate 210 and the like are embedded in necessary portions according to the layout of the members such as the windmill 132 on the game board 100. However, as shown in FIG. The game board 100 is divided into a plurality of sections (in FIG. 9, 16 sections A1 to A16) in a lattice shape, and a magnetic material (iron plate) is provided for each section A1 to section A16 (except for a space-only section). 210) can be attached / detached, the iron plate 210 is accommodated as necessary, and the sensing area of the magnetic sensor 208 is connected in a so-called rosary manner to pinpoint the target position for “magnet goto” detection. You may make it do.
