This makes it possible to improve the stopping accuracy of the pachinko ball delivery device.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment in which the present invention is applied to a pachinko ball feeding device of a pachinko machine will be described with reference to the drawings.
[0008]
The pachinko ball delivery device of this embodiment is composed of a mechanism portion for delivering a pachinko ball and an electronic control device for controlling the mechanism.
[0009]
<Schematic structure of pachinko machine>
First, the schematic structure of the pachinko machine in the present embodiment will be described with reference to FIG. FIG. 4 shows the pachinko machine as viewed from the back side. As shown in FIG. 4, the pachinko machine has a machine frame 1 and a front frame 3 attached to the front surface of the machine frame 1 so as to be openable and closable. The game board 5 is detachably attached to the back surface of the front frame 3. A mechanism plate 7 on which various mechanisms are mounted is rotatably attached to the back surface of the game board 5, and a pachinko that is fed from a pachinko ball feeding device (not shown) on the back surface of the mechanism plate 7. A premium sphere tank 10 for storing spheres is fixed.
[0010]
Below the prize ball tank 10 is formed a lead rod 12 for guiding the pachinko spheres serving as prize spheres in two rows, and the delivery mechanism 20 of the present embodiment is inserted at the lower end thereof. . A ball supply interlock switch 21 is provided in the middle of the lead rod 12 to detect when the number of pachinko balls capable of operating the delivery mechanism is not accumulated. Further, a ball clogging interlock switch 22 for detecting ball clogging or the like in the derivation rod 12 is provided at the end of the derivation rod 12 and immediately before the delivery mechanism 20. The delivery mechanism 20 performs a prize ball delivery operation only when the interlock switch 21 is OFF.
[0011]
The delivery mechanism 20 is for delivering a predetermined number of prize balls according to the winning balls. The winning ball is detected by a detector 24 provided in the winning ball lead-out path 23. In the present embodiment, the winning ball is classified into three according to the type of the winning combination, and three sets of detectors 24 are also provided. This is referred to as a first, second and third start switch (24a, 24b, 24c) in the sense of a signal for starting the delivery of the pachinko ball.
[0012]
Below the delivery mechanism 20, there is provided a discharge bowl 26 that guides pachinko balls counted and released by the delivery mechanism 20 to an upper plate and a lower plate provided on the front surface of the front frame 3. An upper and lower plate interlock switch 27 for detecting that the upper plate and the lower plate are full of pachinko balls is provided in the vicinity of the connecting portion between the discharge bowl 26 and the upper plate and the lower plate.
[0013]
<Feeding mechanism 20>
Next, the configuration of the delivery mechanism 20 will be described. As shown in FIGS. 1 and 3, the delivery mechanism 20 includes a hollow rectangular tube-shaped case 29 opened up and down, and two rows of spheres are disposed at a position corresponding to the lower end of the lead-out rod 12 in the interior thereof. Passages 31 and 32 are provided. Further, inside the case 29, a horizontal shaft 35 whose both ends are supported on the wall surface of the case 29 is provided. Spherical disks 41 and 42 corresponding to two rotating members are connected to the horizontal shaft 35 by the connecting cylinder portion 43. It is pivotally supported so as to be integral and rotatable with respect to the horizontal shaft 35.
[0014]
Each of the ball-cut disks 41 and 42 includes two sprockets 44 having semicircular cutouts Pa at 13 places on the outer periphery, and brackets 45 to which the sprockets 44 are fixed on both sides. As shown in FIG. 1, the ball-cut disks 41 and 42 are provided at positions where the outer circumferences face the inside of the ball passages 31 and 32. Further, since the diameter of the notch Pa provided on the outer periphery of the sprocket 44 is substantially the same as that of the pachinko ball, when the ball-cutting discs 41 and 42 are rotated, one pachinko ball B in the ball passages 31 and 32 is one. As a unit, it is sent to the discharge rod 26. Note that the ball-cut disks 41 and 42 are fixed to each other at a rotational position shifted by exactly ½ of the pitch of the notch Pa, so that the pachinko balls are alternately sent by the ball-cut disks 41 and 42. It has become.
[0015]
On the other hand, a stepping motor 50 is attached to the outside of the case 29, and its rotating shaft 51 is inserted into the case 29, and is inserted between both spherical discs 41 and 42. A worm 47 is fixed to the rotating shaft 51, which meshes with a worm gear 46 provided on the outer periphery of the connecting cylinder portion 43 that connects the two sets of ball-cut disks 41, 42 to decelerate the rotation of the rotating shaft 51. The gear mechanism is configured. Therefore, when the stepping motor 50 is rotated, the worm gear 46 is rotated by the rotation of the worm 47 directly connected to the rotation shaft 51, and the ball-cutting disks 41 and 42 are also rotated to perform the pachinko ball feeding operation. The reduction ratio by the combination of the worm 47 and the worm gear 46 is set to a value at which two pachinko balls are paid out when the rotating shaft 51 makes one rotation.
[0016]
As shown in FIG. 1, a rotating disk 52 corresponding to a rotating body is attached to the root portion of the rotating shaft 51. As shown in FIG. 2, the rotating disk 52 is cut out at two arc-shaped regions on the outer periphery, the cut-out part is a light-transmitting part 53 as a marker part, and the remaining part is a light-shielding part 54 as a non-marker part. The total of the two translucent portions 53 and the total of the two light shielding portions 54 have the same angle. In other words, the entire circumference of the rotating disk 52 is divided into four equal parts at an angle of 90 degrees, and the light transmitting parts 53 and the light shielding parts 54 are alternately arranged in each angle region. At a position sandwiching the outer peripheral portion of the rotating disk 52, a transmission type photo detector 55 using infrared light, for example, as a marker portion detector is fixed to the case 29 which is a stationary part. This transmissive optical detector 55 has a known configuration in which a light emitting element and a light receiving element (not shown) are arranged with their optical axes aligned and spaced apart from each other, and the optical axis is blocked by the light shielding portion 54 of the rotating disk 52. If the light transmitting portion 53 allows the passage of light, it is turned on. Accordingly, when the rotating disk 52 rotates and light transmission / blocking is repeated, a pulse signal is output, and light is transmitted twice in one rotation, so one pachinko ball is eventually sent out. One pulse signal is output each time. Note that the mounting phase of the rotating disk 52 with respect to the rotating shaft 51 is such that the optical axis of the transmissive optical detector 55 comes to the center of the light shielding portion 54 (indicated by P in FIG. 2) at the stop angle position of the stepping motor 50 Is set to
[0017]
<Configuration of Electronic Control Device 60>
Next, the configuration and operation of the electronic control device 60 will be described. As shown in FIG. 5, the electronic control device 60 is composed of a power supply unit 63, an interface unit 65, and a setting unit centered on a one-chip microcomputer (hereinafter referred to as MPU) 61 incorporating an arithmetic logic unit, ROM, RAM, and the like. 67 etc.
[0018]
The power supply unit 63 receives three 24 volt AC from the outside and generates three types of DC voltages VE, VD, and VCC.
[0019]
The interface unit 64 is a circuit that interfaces the input / output port Pi of the MPU 61 with external detectors, switches, lamps, motors, and the like. The level signal input units 81 to 85, the output units 87 and 88, and the integral input Part 90, driver ICs 92 and 93, and the like.
[0020]
The level signal input units 81 to 85 are connected to the interlock switches 27, 21, 22 and the first to third start switches 24a, 24b, 24c via the connector CN, and have a level conversion function and a chattering removal function. Have.
[0021]
The output units 87 and 88 are interposed between the MPU 61 and the light emitting diode LD1 and the photocoupler PC1, and include a transistor to have a current amplification function. The light emitting diode LD1 displays that there is a winning ball that has not been completely discharged due to a stop or the like. In the photocoupler PC1, the output side transistor is connected to the control device (not shown) of the ball launching motor via the connector CN, and the light emitting diode of the photocoupler is turned on and the transistor becomes conductive. It is possible to drive the ball launch motor only when it is.
[0022]
The integral input unit 90 is connected to the transmission type photodetector 55 of the ball delivery mechanism 20 and is composed of resistors R23, R24, R25 and a capacitor C25, and is an output side transistor of the transmission type photodetector 55. It has a function of converting on / off to a signal level of the stabilized power supply VCC and removing noise and taking it in.
[0023]
The driver IC 92 is a sink type integrated circuit that draws currents for driving lamps and solenoids through resistors R31 to R34. When the ports P14 to P17 of the MPU 61 become high level, their outputs are set to low level and connected. These loads are driven by supplying a current from the power source VE to the lamp or the like.
[0024]
The driver IC 93 is the same as the driver IC 92 and is connected to the exciting coils ML1 and ML2 of the stepping motor 50. The exciting coils ML1 and ML2 of the stepping motor 50 are bifilar type as shown in the figure, and a power source VE for power is connected to both centers via a resistor R40. The resistor R40 is for making the holding torque during the one-phase excitation and the two-phase excitation in the 1-2 phase excitation substantially equal, and smoothing the rotation of the stepping motor 50.
[0025]
The setting unit 67 is a circuit that includes setting devices 94a, 94b, 94c, and 96 made of a diode array, and a switch Sw1 for manually paying out a prize sphere. The MPU 61 can sequentially decrease the voltage levels of the ports P34 to P37 to a low level at a predetermined interval, read the states of the ports P20 to P23 at that time, and grasp the setting states of the setting devices 94a to 94c and 96. A bit to which the diode is connected has a value of 0, and a bit to which the diode is not connected has a value of 1. Each of the setting devices 94a to 94c corresponds to the number of prize balls to be paid out by winning balls that pass through the start switches 24a to 24c, respectively. When the setting device 94a is set to “1101”, for example, The number of prize balls when the winning ball passes through the 1 start switch 24a is set to 13.
[0026]
The first bit of the setting device 96 connected to the port P20 is for designating the payout timing of the prize sphere. When the value is set to 0 by connecting a diode, the prize sphere is assigned to consecutive winning spheres. It is set to delay the timing when paying out a plurality of sets. The state of paying out premium spheres for consecutive winning balls will be described later.
[0027]
Processing executed by the electronic control unit 60 having the above configuration will be described with reference to the flowcharts of FIGS. Although not shown, the state of each input port is read at regular intervals using a timer interrupt, and at that time, a winning ball is detected and started from the first to third start switches 24a to 24c. When the signal is input, the start signal input processing routine shown in FIG. 6 is executed.
[0028]
When a start signal is input, the number of the port to which the start signal is input is first read (step 100), and the variable N as a winning ball counter is incremented by 1 (step 110). Subsequently, the port P15 is switched to the high level, the lamp LP2 representing the winning is lit for a predetermined time via the driver IC 92 (step 120), and one of the start switches 24 is specified from the port number read in step 100. Then, a process of setting a predetermined number of prize balls according to the start switch 24 to the variable Si is performed (step 130). In this embodiment, three start switches 24 are provided, and three types of prize balls are prepared according to the types of winning prizes. Thereafter, the variable i indicating the execution timing of this processing routine is incremented by 1 (step 140), the process returns to the main routine, and this processing routine is terminated ("return").
[0029]
FIG. 7 is a flowchart showing an interlock signal processing routine. This is activated when it is detected that any of the interlock signals from the three interlock switches 21, 22, 27 has changed from on or off to off or on as a result of the execution of the input port reading process described above. The When this processing routine is started, it is first determined whether or not the interlock signal has just turned on (step 200), and it is determined that the change in the interlock signal is a change from off to on. Then, a process for setting the flag FIL indicating the interlock state to a value 1 is performed (step 210).
[0030]
Subsequently, it is determined whether or not the interlock signal indicates that the upper plate and the lower plate are full (step 220). If both plates are full, a firing control signal for controlling the ball firing motor is sent. Switch off (step 230), then return to return to end the processing routine.
[0031]
On the other hand, when the change of the interlock signal is from the on state to the off state (step 200), it is determined whether or not all the interlock signals are switched off by the change (step 240). If all the interlock signals are off, the flag FIL is reset to 0 (step 250), the firing control signal is switched on (step 260), and the processing routine is returned to “return”. finish. In this case, a pachinko ball can be launched.
[0032]
If even one of the interlock signals is not turned off (step 240), it is determined whether or not the upper and lower pan interlock signals are turned off (step 270), and both signals are turned off. If so, only the process of switching on the firing control signal (step 260) while the value of the flag FIL remains unchanged. On the other hand, if the upper / lower plate interlock signal is not turned off, nothing is performed, and the process returns to “RETURN” to terminate the execution of this processing routine.
[0033]
The “pachinko ball delivery control routine” shown separately in FIGS. 8 and 9 is executed as follows. This processing routine repeatedly determines whether or not the flag FIL has a value of 0 and whether or not the variable N indicating that there is an unprocessed winning ball is not a value of 0 (steps 300 and 310). When FIL = 0 and N is no longer 0, the processing in step 320 and subsequent steps is started. That is, in the processing routine shown in FIG. 7, when the interlock signal is normally OFF, the flag FIL is set to 0, and when a new winning ball is counted in the processing routine shown in FIG. The “pachinko ball delivery control routine” is executed to start the control for delivering the prize ball.
[0034]
In step 320, a low-frequency pulse is output to the exciting coils ML1 and ML2 of the stepping motor 50 via the driver IC 93, and the stepping motor 50 is activated as shown in FIG. As shown in FIG. 10B, the stepping motor 50 is driven by 1-2 phase excitation, but is driven at a frequency considerably lower than the self-starting frequency of the rotor at the time of starting.
[0035]
When the rotor of the stepping motor 50 is started from a stationary state, it must start to move against the large static friction and the moment of inertia received by the worm gear 46, the worm 47, and the ball cutting disks 41, 42 coupled to the rotor. I must. However, since the rotor itself has gear play and the like, it can freely rotate by excitation. Therefore, the rotor rotated by excitation of a certain phase once returns to the original rotational position in a state where the ball-cut disks 41 and 42 are stationary. During this time, the phase of the excitation pulse applied to the excitation coil progresses one after another, and the rotor repeats small rotations and swings back in a slipping state as seen from the excitation pulse. Then, the vibration starts gradually, and the ball-cut disks 41 and 42 start to move against a large static friction and moment of inertia. This is like a locomotive with a small driving force repeatedly accelerating / stopping, and finally starting a lot of trains by shaking out static friction and inertia.
[0036]
When the stepping motor 50 is stopped, the optical axis P of the transmissive photodetector 55 is located at the center of the light shielding portion 54 of the rotating disk 52 (see FIG. 2), and the optical axis P is blocked. Therefore, the output of the transmission type photodetector 55 is off. However, when the rotating shaft 51 of the stepping motor 50 rotates, and as a result, the ball-cut disks 41 and 42 rotate until only one pachinko ball is released, the optical axis P of the transmission-type photodetector 55 rotates. The light passes through the light transmitting portion 53 of the disk 52 and is positioned at the center of the next light shielding portion 54. For this reason, light is allowed to temporarily pass through the optical axis P, and a pulse signal that temporarily turns on the output of the transmissive photodetector 55 is output (see FIG. 10A). Hereinafter, the pulse signal from the transmission type photodetector 55 is referred to as a “ball feed signal”.
[0037]
The low-frequency driving (step 320) of the stepping motor 50 described above is executed until the above-mentioned ball delivery signal is detected (step 330). After the detection of this signal, the counter C counts the number of pachinko balls delivered. A value of 1 is set (step 340).
[0038]
Subsequently, normal frequency excitation pulses are output to the excitation coils ML1 and ML2 of the stepping motor 50 (step 350), and the determination as to whether or not a ball delivery signal is input from the photodetector 55 is repeated (step 360). The ball-cut disks 41 and 42 that have started to move sufficiently rotate even with a small torque due to a small dynamic friction and inertia. Accordingly, the ball-cutting disks 41 and 42 alternately send pachinko balls, and each time a single pachinko ball is sent in response, a ball feed signal is output from the photodetector 55 one after another. Therefore, every time this ball delivery signal is input, the value of the counter C is incremented (step 370), and the value of the counter C is changed from the variable S0 indicating the number of prize balls set in the processing routine shown in FIG. It waits until it becomes a number obtained by subtracting 1 (step 380).
[0039]
The stepping motor 50 is driven with a normal pulse signal until the value of the counter C becomes (S0 -1), that is, the last one of the number of prize balls, and when it reaches the last one (step 380), it is lowered again. The motor 50 is driven with the frequency pulse (step 390). As a result, as shown in FIG. 9 (A), the last pachinko ball is sent out after some time, and when this is detected by the photodetector 55 and a ball sending signal is output (step 400), The stepping motor 50 is stopped (step 410). In this stop state, the optical axis P of the transmission type photodetector 55 is positioned at the center of the next light shielding portion 54 of the rotating disk 52, and the output state of the photodetector 55 is turned off. In this embodiment, only the last one is driven with the low-frequency pulse, but it may be switched to the low-frequency pulse drive when the remaining number of the pachinko balls is about three. In this way, the stopping accuracy is further improved.
[0040]
As a result of the above processing, the prize ball sending operation for one winning ball is completed. Therefore, the variable N indicating the number of unprocessed winning balls is decremented by 1 (step 420). It is determined whether the value is not equal to 0 (step 430). If the variable N is not 0, then it is determined whether or not the first bit of the setter 96 is 0 (step 440). If the first bit of the setting device 96 has a value of 0, a process of waiting for a time T1 (so-called software timer) is performed (step 450). If not, the process of waiting for a time T2 (T1> T2) is performed. (Step 460), the process returns to step 300 of this routine. During this waiting process, the variable update process of S0 = S1, S1 = S2,..., Si-1 = Si, i = i-1 is performed to deal with the unpaid premium balls.
[0041]
As a result, when the first bit of the setting device 96 is 0, as shown in FIG. 10 (A), there is a continuous winning ball and the prize ball is not paid out continuously, but only for a predetermined time T1. After waiting, a process for sending out the next plurality of pachinko balls is executed. If the first bit is not 0, the payout of prize balls for consecutive winning balls is performed after waiting for a time T2 shorter than the time T1. In each of the above-described flowcharts, steps 300, 310, 330, etc. are expressed as loop processing, but this is a convenient expression for ease of explanation, and actually, without performing loop processing, The routine is temporarily exited.
[0042]
According to the present embodiment described above, when a pachinko ball is sent out, a ball sending signal is output from the transmission photodetector 55 every time one pachinko ball is sent out, and the signal state is changed from OFF to ON. The signal state repeatedly changes from ON to OFF before the next one delivery is performed (when the rotary shaft 51 rotates 90 degrees from the output of the ball delivery signal) (see FIG. 11). Here, in the present invention, since the formation angle regions of the light transmitting portion 53 and the light shielding portion 54 of the rotating disk 52 are set to be equal, the light detection is performed when the pachinko ball is continuously sent out. The light transmitting portion 53 and the light shielding portion 54 correspond to the optical axis of the device 55 at the same time. When this state is observed as a signal from the photodetector 55, a pulse signal train having a duty ratio of 50% is obtained. Therefore, compared to the conventional configuration in which one time is extremely short, stable detection is possible even when the rotating disk 52 rotates at a high speed, and the counting accuracy of the number of pachinko balls sent out increases. .
[0043]
Further, the following effects can be obtained.
(A) In the present embodiment, at the stop angle position of the stepping motor 50, the rotating disk 52 is rotated so that the optical axis of the transmissive optical detector 55 comes to the center of the light shielding portion 54 (indicated by P in FIG. 2). Attached to the shaft 51. For this reason, even if there is some variation in the stop angle position of the stepping motor 50, the optical axis reliably corresponds to the light shielding portion 54, and the occurrence of counting errors can be prevented more reliably.
[0044]
(B) When the stepping motor 50 is started and stopped, the frequency of the excitation pulse applied to the excitation coils ML1 and ML2 is made sufficiently lower than the self-starting frequency, so even the small and small torque stepping motor 50 vibrates the rotor. It can be reliably rotated and stopped using it. Therefore, by reducing the size of the stepping motor 50, it is possible to facilitate attachment to a narrow space on the back surface of the pachinko machine and to improve design flexibility. Incidentally, the size of the stepping motor 50 can be suppressed to about half of the conventional volume ratio in this embodiment.
[0045]
(C) The payout timing of prize spheres for consecutive winning spheres can be switched between two stages by setting the setting unit 96. A supply device for supplying pachinko balls is connected to the pachinko machine, but an optimal value may be selected according to the capability of the ball supply device. it can. Moreover, the optimal timing for paying out the prize balls varies depending on the type of the object and the land pattern. Therefore, in a stand that appeals to the player that the prize balls are paid out without interruption when the winning balls are consecutive, the first bit of the setting device 96 is set to 1 and the payout interval is set to a short time T2, while the prize is given. In a stand that appeals to the player when the ball has been paid out over a relatively long period of time, a long payout interval T1 may be used as in the embodiment.
[0046]
(D) In this embodiment, the stepping motor 50 is used as a drive source. However, unlike the DC motor, the motor is unlikely to continue to rotate due to a short circuit or the like, and is reliable as a pachinko ball delivery device. The nature is high. In this embodiment, even when the stepping motor 50 is stopped at the start and end of the delivery of the pachinko balls, it can be similarly restarted by being driven with a low-frequency pulse.
[0047]
In addition, this invention is not limited to an above-described Example, The following modifications are possible.
[0048]
(1) In the above embodiment, since a transmissive type is used as the photodetector 55, the light shielding portions 54 and the light transmitting portions 53 are alternately formed on the outer peripheral portion of the rotating disk 52 as the labeling portion and the non-labeling portion. However, if a configuration using a reflection-type photodetector is used, the light reflecting portion and the non-reflecting portion may be alternately formed as a set of the labeling portion and the non-labeling portion.
[0049]
(2) Further, the sign detector is not limited to the optically detected type, but may be of a type that electromagnetically detects an object such as a proximity switch. In this case, a metal disk can be used as the rotator, and the projecting piece can be used as a marker and the other can be used as a non-label. In addition, of course, various sensors can be used for the sign detector.
[0050]
(3) As the motor, a multiphase stepping motor having three or more phases may be used, or a unified type stepping motor may be used.
[0051]
(4) In the ball delivery mechanism 20 of the present embodiment, the pachinko balls are delivered one by one when the ball-cutting disk 40 rotates by a predetermined angle, but the delivery unit is not limited to one and is two or more. Of course, it is also good.
[0052]
(5) In the present embodiment, an example is shown in which the present invention is applied to a ball delivery device attached to a pachinko machine. However, the present invention is not limited to this. For example, the present invention is applied to a ball delivery device for a pachinko ball rental device or a pachinko ball counting device. You can also.
