Description

  The present invention relates to a roulette game machine having an automatic leveling device for adjusting a field board horizontally.

In the roulette game machine, it is necessary to adjust the level of the field board periodically after the roulette game machine is operated, not only when it is newly installed.
The field board is kept horizontal so that the ball ejected by the ball shot mechanism rolls in a mortar-shaped field and gradually falls toward the center while drawing a spiral and rolls into one of many squares. Therefore, when the level of the field board is not high, it is impossible to ensure the uniformity and fairness of the probabilities of the squares.
Conventionally, a leveling machine is placed on the field surface and the leveler is manually adjusted by turning the adjuster or adjusting screw by hand, which is inefficient and time consuming. Further, even if there is a slight deviation after adjustment, it is difficult to make adjustments so that the same conditions are difficult to understand.

Therefore, in order to solve the above problem, the present applicant has proposed a roulette game machine including an automatic leveling device (Patent Documents 1 and 2).
Japanese Patent Application Laid-Open No. H10-228688 can automatically and efficiently perform the adjustment in a short time without manual operation by adjusting the level using a tilt sensor. Japanese Patent Laid-Open No. 2004-228561 finely adjusts the pedestal elevating device to a horizontal state so as to bring the field plate into a horizontal state and obtain the deviation of the ball appearance on the field plate to be equal.
Japanese Patent Laid-Open No. 06-210046 Japanese Patent No. 3171504

  Patent Documents 1 and 2 have a problem that there are many members of the mechanical mechanism of the horizontal adjustment mechanism because the whole apparatus is supported at four points and a mechanism that moves up and down at all fulcrum positions is employed. In addition, this vertical mechanism is provided with an eccentric cam on the machine base, the cam surface is abutted against the base of the field panel, and the horizontality is adjusted by rotating the eccentric cam by driving a motor. Therefore, since the load of the field board is directly applied to the cam surface, a torque for rotating the cam is required, and there is a difficulty in fine vertical adjustment.

  The object of the present invention is that the number of upper and lower mechanical mechanisms used is smaller than that of a conventional leveling device, and a heavy field board can be moved up and down easily and with subtle movements. Another object of the present invention is to provide a roulette game machine that can automatically adjust the level of a field board surface without bothering a person during periodic inspection.

In order to achieve the above object, a first aspect of the present invention provides a field board support plate for supporting a mortar-shaped field board that draws a spiral trajectory while the ball rolls and falls toward the center, and the field board. In the roulette game machine having a leveling device capable of adjusting the level of the field board between the machine base on which the support plate is mounted, the leveling device is a fixed fulcrum provided on the lower surface of the field board support plate.

Control means for controlling the movement of the inclined surfaces of the upper and lower mechanical parts to adjust the inclination between the fixed fulcrum and the first operation fulcrum and the second operation fulcrum, thereby leveling the field board surface;
It is characterized by having.
A second aspect of the present invention is characterized in that, in the first aspect of the present invention, the fulcrum of the fixed foot portion and the first and second motion foot portions is located at the apex position of an equilateral triangle.

And a shaft having a lead screw portion, and a block having a screw portion meshing with the lead screw portion and having a V groove on an inclined surface.
According to a fourth aspect of the present invention, in the invention according to the third aspect, the first and second action feet are ball casters.
According to a fifth aspect of the present invention, in the first aspect of the present invention, the control means starts leveling control when the power is first turned on after the roulette game machine is installed.
According to a sixth aspect of the present invention, there is provided the counting means for counting the number of games of the roulette game machine according to the first aspect of the invention, and a game number monitoring unit for monitoring whether or not the game number has reached a predetermined number. The control means starts leveling control when the game number monitoring unit detects that the predetermined number of times has been reached.

  According to the above configuration, even a heavy field board can be easily moved, and a delicate vertical movement is possible. It is possible to automatically adjust the level of the field board surface without bothering people during game machine installation or periodic inspection. Thereby, it is possible to eliminate the bias by the rotation and drop movement of the ball during the roulette game.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing an appearance of a roulette game machine with an automatic leveling device according to the present invention, and FIG. 2 is a side view of the roulette game machine with an automatic leveling device of FIG.
On the bottom of the mortar-shaped field board 1, a large number of meshes 1 a are formed to indicate the output. When the ball is ejected in the circumferential direction of the field board by a ball shot mechanism (not shown), the ball rolls and gradually falls in a spiral, and the drop is determined to fall into one of the cells 1a.
The field board 1 is covered with a bowl cover 2 around the field board, and is mounted on a roulette main frame 4 which is a field board support plate via a solenoid base board 3.

A roulette mechanism 6 is constructed by integrating an assembly part composed of the field board 1, bowl cover 2, solenoid base board 3 and roulette main frame 4 and a mechanism for rotating a field board (not shown) and a mechanism for injecting a ball. ing.
As shown in FIG. 2, the roulette mechanism 6 has a shape in which a central lower portion protrudes downward. The machine base 5 on which the roulette mechanism 6 is mounted has a roulette mechanism housing 5a at the center. Between the roulette main frame 4 of the roulette mechanism 6 and the upper surface of the machine base 5, support means (fixed foot and fixed foot receiving portion, operating foot and vertical mechanism) of the leveling device are arranged. By supporting the roulette mechanism 6, the roulette mechanism 6 is mounted on the machine base 5 and a roulette game machine is assembled.

The leveling device has a fixing support means consisting of a fixed foot portion and a fixed foot receiving portion as a fixed fulcrum 8, an operating foot portion as an operation fulcrum 9, 10 and an upper and lower mechanical means consisting of two upper and lower mechanical portions. The fixed support means and the upper and lower mechanical means are arranged at the apex position of the equilateral triangle.
An inclination sensor 11 is installed on the roulette main frame 4 side along the fixed fulcrum 8 and the operation fulcrum 9, and the inclination between the fixed fulcrum 8 and the operation fulcrum 9 can be detected. Similarly, an inclination sensor 12 is installed on the roulette main frame 4 side along the fixed fulcrum 8 and the operation fulcrum 10, and the inclination between the fixed fulcrum 8 and the operation fulcrum 10 can be detected.

FIG. 3 is a view of the AA direction of FIG. 2 and shows the lower surface of the roulette mechanism.
Ball casters 13 and 14 which are operation feet are provided at the positions of the operation fulcrums 9 and 10. The fixed fulcrum 8 is provided with the upper half of the fixed support means, that is, a spherical foot 15a (see FIG. 7) which is a fixed foot.
The inclination sensor 11 is arranged in parallel to the line connecting the fixed fulcrum 8 and the operation fulcrum 9 and in the vicinity of the fixed fulcrum 8. Similarly, the tilt sensor 12 is also disposed in parallel to the line connecting the fixed fulcrum 8 and the operation fulcrum 10 and in the vicinity of the fixed fulcrum 8. The reason why the inclination sensors 11 and 12 are arranged in the vicinity of the fixed fulcrum 8 is to eliminate the influence of the inclination between the operation fulcrums 9 and 10 as much as possible.

FIG. 4 is a view of the BB direction of FIG. 2 and shows the upper surface of the machine base.
The position of the fixed fulcrum 8 is fixed to the fixed fulcrum means mounting rod 18 hung on the roulette mechanism accommodating portion 5a, and the lower half of the fixed support means, that is, the spherical foot support 15b (FIG. 7) Is installed). Further, there are operating fulcrums 9 and 10 on the upper surface 5b of the machine base 5 with the roulette mechanism portion accommodating portion 5a interposed therebetween, and the upper and lower mechanical portions 16 and 17 are respectively disposed on these portions.

FIG. 5 is a perspective view for explaining details of the upper and lower mechanical parts, and FIG. 6 is a cross-sectional view showing a state in which a ball caster is placed on the upper and lower mechanical parts.
This figure explains the up-and-down mechanical unit 16, and the up-and-down mechanical unit 17 has the same configuration.
The upper and lower mechanical support fittings 27 have a rectangular accommodating portion 27f, and holes 27a, 27b and 27c are formed in attachment portions 27g and 27h developed at the upper end of the rectangular accommodating portion 27f.

The rectangular block 26 includes a slope having a V groove 26b formed therein, and has a through hole 26b having a screw portion 26a on the inner wall. A shaft 25 having a lead screw portion 25a at the center is inserted into the through hole 26b, and the lead screw portion 25a and the screw portion 26a are engaged with each other. Both ends of the shaft 25 are rotatably attached to the front and rear walls of the rectangular housing portion 27f. A gear 24 is attached to one end of the shaft 25.
The DC motor 22 is attached to the lower surface of the upper and lower mechanical support brackets 27 by a motor fixing bracket 29. A gear 23 is attached to the shaft 22 a of the DC motor 22, and the gear 23 is engaged with the gear 24 described above.
The upper and lower mechanical parts configured as described above are fitted into an opening (see FIG. 4) provided on the upper surface of the machine base 5, and the lower surfaces of the attachment parts 27 g, 27 h and 27 i are pressed against the upper surface of the machine base 5. The upper and lower mechanical parts are fixed to the machine base 5 by passing screws through the holes 27a, 27b and 27c and fastening them.

  The rotational output of the DC motor 22 is transmitted to the shaft 25 via the gears 23 and 24. As the shaft 25 rotates, the block 26 moves in the directions of arrows 30 and 31 due to the engagement of the lead screw portion 25a and the screw portion 25. As the block 26 moves in the horizontal direction, the ball 28 of the ball caster 13 mounted in the V groove 27b moves in the vertical direction (arrow 32) without moving the operation fulcrum back and forth. Since the rotation of the DC motor 22 is transmitted to the shaft 25 via the gears 23 and 24 and the block 26 having the screw portion 26a screwed with the lead screw portion 25a of the shaft 25 is moved in the horizontal direction, The ball on the slope is moved up and down little by little with a large torque by the high-speed rotation of the motor.

  A front limit sensor 20 and a rear limit sensor 21 made of a photo interrupter for restricting the longitudinal movement of the block 26 are installed on the inner wall of the rectangular housing portion 27f. A plate (not shown) attached to the back surface of the block 26 reaches the front limit sensor 20 or the rear limit sensor 21 by the back and forth movement of the block 26 and enters between the light emitting unit and the light receiving unit, thereby blocking the light. The movement to the limit position of the block 26 is detected by ON / OFF change of the front limit sensor 20 or the rear limit sensor 21.

7A and 7B are views showing the external appearance of the fixing support means, where FIG. 7A is a perspective view and FIG. 7B is a cross-sectional view.
A spherical foot 15 a fixed to the lower surface of the roulette main frame 4 of the roulette mechanism is fitted into a spherical hole portion of the spherical foot receiving base 15 b fixed to a fixing support means mounting rod 18 spanned on the machine base 5. The fixed support means 15 is configured in the combined state.

FIG. 8 is an exploded sectional view of the tilt sensor.
This figure explains the mounting structure of the tilt sensor 11, and the tilt sensor 12 has the same configuration.
A tilt sensor mounting plate 42 shown in FIG. 5C is mounted on the roulette main frame 4. The inclination sensor 11 having the output unit 40 shown in (a) is attached to the inclination sensor support plate 41 shown in (b) and attached to the inclination sensor attachment plate 42 as shown in (d).
The inclination sensor 11 is filled with a conductive liquid, and outputs a voltage value corresponding to the inclination angle from the output unit 40 by detecting a resistance between two electrodes. For example, if the 2.5V output is in a horizontal state, the inclination angle is obtained with a voltage value increased or decreased with respect to 2.5V.

FIG. 9 is a circuit diagram showing an embodiment of a circuit of a roulette game machine with an automatic leveling device according to the present invention. This circuit describes only the circuit section directly related to the present invention, and the medal insertion detection section, projector (display section), image processing circuit for projector display, ball control mechanism, ball control drive circuit, etc. are omitted. It is.
The ROM 52 stores a demonstration program for displaying a demonstration during standby, a roulette execution program for executing a roulette game, and necessary data. Further, a level check program for adjusting the level when the power is turned on and when a predetermined number of games is reached is stored as a management program. The RAM 53 is used as a work area used when the CPU 51 performs calculation and processing, and is used for temporarily storing generated data information. The CPU 51 controls the control unit, drive circuit, detection unit, and video circuit according to the sequence and detection information based on the read roulette execution program.

The levelness monitoring unit 51a, the game number monitoring unit 51b, the game number counting unit 51c, and the levelness determination unit 51d related to the operation of the leveling device in the present invention are realized by the functions of the CPU 51.
The level monitoring unit 51a instructs the sensor control unit 64 to obtain the output value (voltage value) from the tilt sensor 11 or 12. The horizontality determination unit 51d corrects the inclination when the output value is on the + side or the − side (inclination occurs) with respect to a value indicating horizontal (reference voltage value, for example, 2.5 V). Is sent to the vertical mechanical drive circuit 55. The vertical mechanical drive circuit 55 rotates the DC motor 22 or 38 (motor on the vertical mechanical unit 17 side) to move the operating fulcrum 9 of the vertical mechanical unit 16 or the operating fulcrum 10 of the vertical mechanical unit 17 up or down. As a result, the output value from the inclination sensor 11 or 12 gradually approaches a value indicating horizontal, and when the output of the inclination sensor 11 or 12 reaches the reference voltage value, the horizontality determination unit 51d stops the DC motor 22 or 38. Then, the movement of the vertical mechanical part 16 or 17 is stopped.

In the above operation, when the block 26 moves back and forth, it does not become horizontal, and when the block 26 moves to a position just before the ball 28 of the ball caster 13 is removed from the V groove 27b, the front limit sensor 20 or The rear limit sensor 21 is turned on. In response to the ON signal, the level determining unit 51d stops the vertical mechanism 16 or 17 so that the vertical mechanism 16 or 17 does not fall out of the controllable range.
The power switch 57 is turned on by an administrator. When the power switch 57 is turned on, the power circuit 58 is activated and power is supplied to each circuit unit. When the power switch 57 is turned on, the CPU 51 reads the level check program from the ROM 52 and starts up an operation sequence for leveling the roulette game machine. Necessary information and results at the time of start-up are displayed on the liquid crystal display unit 61 (a display unit provided for management or a screen used for a game).
The game number counting unit 51c is a circuit for counting the total number of games played by the player, and the game number monitoring unit 51b determines whether or not the count value of the game number counting unit 51c has reached a predetermined number of games. This is a circuit for instructing the horizontality monitoring unit 51a to enter a horizontal adjustment operation when the predetermined number of times is monitored. The predetermined number of times can be set by the administrator on the screen displayed on the liquid crystal display unit 61, and is set to 150 times or 200 times, for example.

FIG. 10 is a flowchart for explaining the leveling operation of the circuit of the roulette game machine with an automatic leveling device according to the present invention. (A) is when the power is turned on, and (b) reaches the predetermined number of games. This is the operation when
In the flowchart of (a), when the power is turned on (step (hereinafter referred to as “S”) 001), a screen for starting the operation of checking the levelness is displayed on the liquid crystal display unit 61, and the leveling adjustment sequence operation starts. The horizontality check program is started (S002), the horizontality monitoring unit 51a obtains an output from the tilt sensor 11, and the horizontality determination unit 51d compares the reference voltage value indicating the level with the value sent from the tilt sensor. It is determined whether an inclination has occurred (S003). If the value output from the tilt sensor 11 is different from the reference voltage value, it is determined that the tilt sensor 11 is tilted, and a control signal corresponding to the different value is output. That is, the vertical mechanical drive circuit 55 is controlled so that correction is made to the-side when tilted to the + side relative to the horizontal, and correction is made to the + side when tilted to the-side. As a result, the DC motor 22 rotates in a direction to correct the tilt, and the block 26 of the upper and lower mechanical unit 16 slightly moves upward or downward (S004).

  While the motor is being driven, the output value of the tilt sensor 11 is monitored, and the operations of S003 and S004 are repeated until the state becomes horizontal. When the output of the tilt sensor 11 reaches the reference voltage value, the levelness determination unit 51d sends a signal to stop the motor to the vertical mechanical drive circuit 55. As a result, the space between the fixed fulcrum 8 and the operation fulcrum 9 of the field board becomes horizontal. Next, by obtaining an output from the tilt sensor 12, the same leveling adjustment operation is performed between the fixed fulcrum 8 and the operation fulcrum 10. When the field board 1 is in the horizontal state as described above, the horizontal adjustment operation sequence is completed.

Next, the horizontal adjustment operation when the number of games reaches a predetermined number will be described.
In the flowchart of (b), when the game starts (S005), the game number counting unit 51c counts up every time the game is finished. The game number monitoring unit 51b monitors whether or not the count value of the game number counting unit 51c has reached a predetermined number (S006). When the count value reaches a predetermined number of times, a periodic check operation is started (S007).
Thereby, in S008 and S009, the same operation as in S003 and S004 is performed, and when the tilt is generated, the field board 1 is controlled to be horizontal. When this operation ends, the game number counting unit 51c is reset, counts the number of games again, and when the predetermined number of games is reached, the level of the field board 1 is adjusted.
The periodic check operation sequence is preferably started after the predetermined number of games has been reached and the player's game is over.

In the embodiment of the present invention, one fixed fulcrum and two operation fulcrums are configured to be positioned at the apex of the equilateral triangle. However, it is not always necessary to be at the apex of the equilateral triangle. It may be the top.
Moreover, although the example which performed the level adjustment operation | movement between a fixed fulcrum and a 1st operation point and between a fixed fulcrum and a 2nd operation point was demonstrated in order, you may perform simultaneously.
