Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine having discharge means for discharging a number of game balls corresponding to the operation amount of a pulse motor.

[0002]

2. Description of the Related Art In some gaming machines, a discharge mechanism is operated by rotation of a pulse motor to discharge a number of game balls proportional to the operation amount of the pulse motor (for example, see Japanese Patent Application Laid-Open No. Hei 6-1994). No. 47154). In this case, as shown in FIG. 13, in the pulse motor (the number of driving phases = 4), a plurality of stator-side magnetic poles 111 of the first to fourth phases (L1 to L4) are sequentially arranged, and are adjacent to each other. Fit 2
The two stator-side magnetic poles 111 (the first and second phases, the second and third phases, the third and fourth phases, the fourth and first phases) were sequentially excited, and were excited. Stator magnetic pole 111
The rotor-side magnetic poles 121 face each other, and the rotor 120 rotates.

[0003]

However, in a gaming machine using such a pulse motor, a game ball 1
If the motor rotation angle corresponding to the ejection of the game balls is not a multiple of the product of the step angle of the motor (the angle between the adjacent stator-side magnetic poles 111) and the number of drive phases (= 4),
After the game ball is discharged, the pulse motor moves to the initial position (first and second phases).
Since the rotor magnetic pole 121 does not return to the position where the stator magnetic pole 111 is opposed to the stator magnetic pole 111 of the layer, the drive control of the motor cannot be performed correctly, and the game ball cannot be properly discharged. For this reason, a pulse motor that satisfies the rotation angle for discharging one game ball = the step angle × the number of driving phases × n (n is a natural number) must be used as the pulse motor, and the range of motor selection is narrow.

The present invention has been made in view of such a problem. In a gaming machine provided with a discharging means for discharging a number of game balls corresponding to an operation amount of a pulse motor, a pulse motor can be freely selected. It is an object of the present invention to provide a pulse motor capable of properly controlling the drive of a pulse motor regardless of the type of the pulse motor selected.

[0005]

According to a first aspect of the present invention, there is provided a gaming machine provided with a discharging means for discharging a number of game balls corresponding to an operation amount of a pulse motor, wherein the operation of the pulse motor in the previous discharging of the game ball is performed. Initial position determining means for determining the initial position of the operation of the pulse motor in the current game ball ejection based on the initial position and the operation amount, and initial driving of the pulse motor based on the initial position determined by the initial position determining means Initial drive mode adjusting means for adjusting the mode.

In the second invention, the initial drive mode adjusting means includes an initial drive mode adjusting means for determining whether the rotation angle of the pulse motor corresponding to the ejection of one game ball is not a multiple of the product of the step angle of the pulse motor and the number of drive phases. Change the driving mode.

According to a third aspect of the present invention, there is provided a fixing means for fixing an operation position of the pulse motor.

[0008]

According to the first aspect of the present invention, the initial position of the operation of the pulse motor in the current discharge of the game ball is determined based on the initial position and the operation amount of the operation of the pulse motor in the previous discharge of the game ball, The initial driving mode of the pulse motor (for example, which phase magnetic pole of the stator of the pulse motor is first excited) is adjusted based on the initial position. Therefore, the rotation angle of the pulse motor corresponding to the ejection of one game ball is not a multiple of the product of the step angle of the pulse motor and the number of drive phases, and the pulse motor returns to the same operation position as before the ejection of the game ball after the ejection of the game ball. Even if there is no pulse motor, the driving of the pulse motor can be started without any problem, the discharge of the game balls using the pulse motor can be controlled correctly, and the degree of freedom in selecting the pulse motor is expanded.

In the second invention, the initial drive mode is changed only when the rotation angle of the pulse motor corresponding to the ejection of one game ball is not a multiple of the product of the step angle of the pulse motor and the number of drive phases. For example, according to the embodiment, when the stop position number is an even number, the first and second phase stator-side magnetic poles are excited as usual in the initial stage of driving of the motor, whereas when the stop position number is an odd number, the initial position is initialized. The driving mode is changed, and the third and fourth phase stator-side magnetic poles are excited at the initial stage of driving the motor. Therefore, the change of the initial drive mode can be minimized, and the control can be simplified.

In the third aspect, the operating position (rotational position of the rotor) of the pulse motor is fixed by a fixing means (for example, the stopper member 75 and the stopper solenoid 76 in the embodiment).
The power to the pulse motor is turned off.
In this case, the pulse motor does not rotate with the weight of the game ball (exceeding the play of the fixing means), and the pulse motor stops at the stop position (the initial position at the next discharge).
Is maintained. Therefore, the drive control of the motor can be performed correctly.

A gear (70) is provided, and the rotation of the sprocket is restricted in the direction of the prize ball discharge by ratchet teeth (73) provided on the rotation restricting gear, and is allowed only in the direction opposite to the prize ball discharge. I have. Therefore, a state in which the rotation of the sprocket is restricted by the rotation restricting means is generated, and the drive source is simply brought into the uncontrolled state (the state in which the pulse motor is not excited). Positioning for ejection is performed. For this reason, the prize ball can be discharged by the discharging means without the need for a sensor for positioning, and the cost can be reduced.

Performs lending ball detection. These detection signals are input to the game control device 42 and the discharge control device 43 via the relay board 94.

FIG. 10 is a flowchart showing a processing procedure of the discharge control main process in the discharge control device 43.

In step S1, an initialization process is performed, and processes such as clearing the RAM in the discharge control device 43 are performed.

In step S2, it is determined whether or not there has been a discharge request from the game control device 42 (a prize ball discharge command for requesting prize ball discharge). Set the number of balls in the discharge counter.

In step S4, the stop position numbers of the sprockets 62a and 62b at the end of the previous discharge are obtained. In a succeeding step S5, it is determined whether or not the stop position number is an even number. If the stop position number is an even number, the process proceeds to a step S6 to excite the first phase and the second phase of the stator-side magnetic pole 111 of the ball discharge motor 51, Proceed to step S8. On the other hand, if the stop position number is not an even number, the process proceeds to step S7, where the third and fourth phases of the stator-side magnetic pole 111 of the ball discharge motor 51 are excited, and the process proceeds to step S8.

More specifically, the ball discharge motor 51 is

The phases (L1 to L4) are arranged sequentially. Then, two adjacent stator-side magnetic poles 111 (first and second phases, second and third phases, third and fourth phases, fourth and first phases)
Are sequentially excited, the rotor-side magnetic pole 121 is opposed to the excited stator magnetic pole 111,
The rotor 120 rotates.

In such a ball discharge motor 51, if the stop position number is an even number, the stator 120 is stopped in a state where the first phase and the second phase are excited as shown in FIG. Therefore, also in the current motor drive, the first and second phases are first excited (step S6). If the stop position number is an odd number, first, the third phase and the fourth phase are excited (step S7).

When the rotor 120 of the ball discharge motor 51 is fixed by the stopper member 75 by turning off the power supply to the ball discharge motor 51 and demagnetizing the stopper solenoid 76, FIGS. 11B and 12B As shown in the figure, the stopper member 75 slightly rotates due to the play of the game ball. However, in FIG. 11, the first phase and the second phase
When the stator-side magnetic poles 111 of the phase are excited, and in FIG. 12, the stator-side magnetic poles 111 of the third phase and the fourth layer are excited,
(A), it is returned to the correct initial position (stop position) as shown in FIG. 12 (A), and the operation of the ball discharge motor 51 starts from this correct initial position.

In step S8, the stopper solenoid 7
6, the ball discharge motor 51 can be driven. In step S9, the excited stator-side magnetic pole 1 is turned on.
11 is moved to the next six phases (six), and one game ball is discharged. In step S10, the stop position number is updated by +1. In step S11, the value of the discharge counter is updated by -1.

In step S12, it is determined whether or not the value of the discharge counter has become 0. If the value does not become 0, the process returns to step S9, and the discharge of the game balls by driving the ball discharge motor 51 is repeated. On the other hand, if the discharge counter becomes 0, the process proceeds to step S13, the stop position number at that time is stored, the stopper solenoid 76 is turned off in step S14, and the energization of the ball discharge motor 51 is turned off in step S15. Then, the process returns to step S2.

As described above, in the present embodiment, the discharge control device 43 determines the initial position (the stop position number at the time of the previous drive start) and the operation amount (the number of updates of the stop position number) of the ball discharge motor 51 in the previous drive. ), The initial position of the ball discharge motor 51 in the current drive (stop position number at the time of the previous drive stop and the start of the current drive) is calculated, and based on the determined initial position, the ball discharge motor 51 is driven. An initial driving mode (which phase of the stator-side magnetic pole 111 is excited) is determined. Therefore, the rotation angle of the ball discharge motor 51 for discharging one game ball is not a multiple of the product of the step angle of the ball discharge motor 51 (the angle of the adjacent stator-side magnetic pole 111) and the number of drive phases. Regardless, the ball discharge motor 51 can be driven correctly.
