Description

Description: TECHNICAL FIELD The present invention relates to a position detection method in a pachinko machine for detecting the position of a movable member provided in a winning device of a pachinko machine or the like.

<Prior Art> As is well known, a pachinko machine is provided with a down-flow direction changing device, various prize winning devices, and the like, and these down-flow direction changing devices, a winning device, and the like have a movable member. By moving the pachinko game, the downflow direction is changed, and the form of winning in the prize-winning device is changed, thereby increasing the interest of the pachinko game.

For example, in Japanese Unexamined Patent Publication (Kokai) No. 61-187879, a down-flow direction changing device, that is, a so-called windmill is provided with a rotational position detecting device, and the pachinko game is changed based on the rotation of the windmill. Also, JP-A-63-257588 and JP-A-
In the prize winning device described in JP-A-63-111894, a scheme has been devised to enhance the interest of pachinko games by changing the winning configuration of balls by a movable member provided in the prize winning device.

Therefore, in the case of a movable member such as a windmill or a prize device, if the reference position (origin) of the movable member or the relative position to the reference position is not known, or if the stop position of the movable member is not known, the movable member is movable. Inability to control the movement of the members.

Accordingly, there are various methods for determining the reference position of the movable member and detecting the stop position, but basically the following two methods are employed.

That is, as a first method, a detector for detecting a reference position and a detector for detecting a stop position are separately provided, and a reference position and a stop position are respectively detected based on detection outputs of both detectors. There is. As a second method, there is a method in which only a detector for detecting a reference position is provided, and a stop position is relatively calculated based on an elapsed time from a time when the detector passes the reference position.

<Problems to be Solved by the Invention> According to the above-described first method of providing a plurality of detectors, the detection accuracy at both positions is improved, but since a plurality of detectors must be attached, the space is limited. The mechanism is complicated due to heavy consumption, and the number of input systems also increases on the control device side.

On the other hand, according to the method of detecting the reference position and calculating the stop position over time, the number of detectors is small,
The mechanism is simplified, but accuracy remains problematic. In other words, even if the predetermined time has elapsed, if the movable member has temporarily stopped for any reason, such as an external force applied to the movable member,
Alternatively, when the movable member does not move at a predetermined moving speed, the movable member does not always move as set. Therefore, the movable member may not stop at a predetermined position.
In addition, even when the pulse motor is used as a drive source, even if a predetermined number of pulses are supplied, the pulse is not necessarily rotated by a predetermined angle.

<Means for Solving the Problems> According to the position detection method for a pachinko machine proposed in view of the above, the present invention forms an identification portion on a movable member provided in a pachinko machine and can detect this identification portion. In a position detecting method for a pachinko machine in which a detection means is provided and the detection output of the detection means is used as identification information, a plurality of identification parts are provided on a movable member, and a traveling direction of a main identification part which is an origin position among the identification parts is provided. The sub-identifying section is formed in the vicinity of, and when the detecting means sends out the detection output again within a predetermined time after sending out the detection output, it is determined that the previous detection output is the detection output by the preceding sub-identification section. , The subsequent detection output is determined to be the detection output by the main identification unit at the origin position, and the position of the main identification unit is identified as the origin.

<Operation> Of the plurality of identification units provided on the movable member, the main identification unit can be specified by detecting the sub-identification unit that is close to the main identification unit serving as the reference position within a predetermined time.

<Example> Hereinafter, when describing the present invention for drawings showing the embodiments, the first view to FIG. 7 is intended to illustrate the basic form of the present invention method, FIG. 1 is a plan of the movable member at the time T ₀ shows a diagram, a side view of FIG. 2 ibid, plan view of FIG. 3 is a movable member at time T _n, the flowchart for Figure 4 is the reference position detection, the time chart of Fig. 5 ibid, 6 The figure shows a time chart for detecting the rotation stop position, and FIG. 7 shows a flowchart of the above. The detection switch as the detection means may be an optical sensor (a photo sensor or the like) including a pair of light emitting elements and a light receiving element, a mechanical switch using a micro switch or the like, or a magnetic switch such as a proximity switch or the like. It may be a vessel.

First, method for detecting the reference position (origin) P _0, i.e. the initial setting will be described. For example, it is assumed that the positional relationship between the detection switch as the detection means S and the movable member Q when the power is turned on is in the state shown in FIG. In this state, when the power source is turned on to turn on the motor which is the drive source of the movable member Q and the movable member Q starts rotating in the direction of the arrow (clockwise), the detection switch as the detection means S is provided at the point B first. Identification section
Detecting the notch is P _1, and sends the detection output detection switch is turned on. On the basis of the detection output of the detection switch, for example, an electrical control device having a microcomputer configuration (not shown) starts a timer and starts measuring time,
It is determined whether there is a next detection output within a predetermined time t. That is, when there is no-one of the detection switch by notches provided in the next identification portion P _x is within a predetermined time t, it is to determine the notch previously detected as being a mere identification portion P _1. When rotating the movable member Q further detects a notch which is next identification portion P _2, since this is no next detection output within the predetermined time t may be determined that the mere identification unit P _2. Furthermore the detection switch and the movable member Q is rotated, detects the notch of the main identification unit sub identifying part P 'in which A' point provided in the traveling direction the vicinity of the main identification unit P ₀ to precede the P ₀ turned, followed within a predetermined time t, is turned on by detecting the notch of the point a is a primary identification unit P ₀ located in the vicinity of the sub-identifying section P '. Accordingly, the control unit receives the detection output continuously within a predetermined time t, determining the notch detected earlier and sub identification portion P ', since it is determined that the main identification unit P ₀ is the origin of the cutout subsequent is there. Then, the movable member Q is stopped with the notch at the point A as the origin.

According to the above, no matter what position the movable member Q is stopped when the power is turned on, the movable member Q can be returned to the origin and initialized.

Next, a method of stopping the movable member Q located at the origin at a predetermined position as described above will be described with reference to FIGS. 6 and 7. FIG.

When the motor of the movable member Q stopped at the origin is turned on, the movable member Q starts rotating, the detection switch is turned on at the notch at the point B, and the counter is incremented (+1) based on the detection output of the detection switch. The counter value is set to “1”. Since this position in a less than the counter value is "3" stops the movable member Q turns off the predetermined period of time t ₂ the motor.

Then, by turning on the motor When the predetermined time t ₂ has passed to rotate the movable member Q, the notch in the detector at the point C is turned on, the counter value increments the counter on the basis of the detection output "2" And Even at this position, the counter value is still less than “3”, so that the motor is stopped for a predetermined time t ₂
And the movable member Q is stopped. Then, when the motor is turned on again to rotate the movable member Q, the detection switch is turned on at point A ', and the counter is incremented based on this detection output to set the counter value to "3". When the counter value becomes "3", the counter is reset. At this time, the movable member Q continues to rotate while the motor remains on. The next notches, i.e. stopped for a predetermined time t ₂ based on the detection output of the detection switch at the origin A.

Thus, the movable member Q can be stopped at a predetermined position for a predetermined time. That is, according to the illustrated embodiment, the movable member Q stops at three places including the origin.

Next, a case where the movable member Q rotates bidirectionally will be described as a second embodiment.

For example, in the case of the movable member Q that stops at three places including the origin, as shown in FIG.
Although P ₀ and the identification portions P ₁ and P ₂ are provided and the sub-identification portion is provided, in this embodiment, since the movable member Q rotates in both directions, the vicinity of both sides of the notch serving as the main identification portion P _{0 at the} point a is provided. Notches are provided at the points a ′ and a ″, respectively, to form sub-identifiers P ′ and P ″.

In FIG. 8, when the initial rotation direction is set to the first rotation direction (clockwise) and the detection switch as the detection means S is located between the notch at point a and the notch at point a '. , The origin is detected according to the flowchart shown in FIG. That is, by turning on the power motor is turned on, the movable member Q starts to rotate in a first rotational direction and on detection switch is the main identification unit P ₀ provided to the point a. Then, the timer starts counting, and the detection switch is turned on by the sub-identifying unit P "provided at the next point a" within a predetermined time t, and the motor continues to be on and the rotating member Q is turned on. Continue spinning. When turned on detection switch by the identification portion P ₁ provided on a point b, the detection by the timer is to start counting after starting, the identification unit P ₂ provided in c the following points within a predetermined time t switch Since there is no ON, the process proceeds to the next step and waits for the ON of the detection switch. When the detection switch by the identifying part P ₂ of the point c is turned on, similarly to the timer starts timing. However, also in this case, since the detection switch is not turned on by the next identification unit within the predetermined time t, the motor continues to be turned on and the movable member Q continues to rotate. Then, the detection switch is turned on 'sub-identifying section P' of the point a, the detection switch in the main identification portion P ₀ of the point a within a predetermined time t is turned on again, the motor is determined that the origin where Stop.

Further, in order to stop the movable member Q at each stop position, control is performed according to, for example, a flowchart shown in FIG. 11 and a time chart shown in FIG.

That is, the movable member Q which have stopped at the main identification section P ₀ provided on a point which is the origin as described above, when stopped at the identification unit is rotated in a first rotational direction following become. When the rotation of the movable member Q is started by turning on the motor, the detection switch is turned on at the sub-identifying section P ″, so that the counter is incremented to set the counter value to “1”, and the motor continues to be turned on, and member Q also continues to rotate. When the detection switch by the identifying part P ₁ of the point b is turned on, the counter value is incremented counter "2"
And then, it stops the movable member Q of a motor by the predetermined time t ₃ off. Resumes rotation of the movable member Q to turn on the motor When the predetermined time t ₃ has elapsed, waits for the detection switch by the identifying part P ₂ in the following points c are turned on. After the detection switch is turned on by the identification portion P ₂ of the point c, and the counter value is incremented counter is "3", the motor for a predetermined time t ₃ stops. When the detection switch is turned on at the sub-identifying section P 'at the next point a', the counter is incremented to set the counter value to "4", and the counter is reset to set the main identifying section P at the point a which is the origin. Return to ₀ .

If, as described above, can be a movable member Q is a predetermined time stopping t ₃ at a predetermined position.

When the movable member Q is rotated in the second rotation direction (counterclockwise), the difference is which one of the sub-identifying portions P ′ and P ″ appears first, so a time chart is shown in FIG. Is omitted.

Next, the winning device 1 of the pachinko machine to which the above-described position detection method is applied will be described.

In the gaming board 2 shown in FIG. 14, a prize winning device 1 is disposed substantially at the center of a game section 4 surrounded by a guide rail 3.
The first starting port 5a and the second starting port 5b are provided below the winning device 1
An out port 6 is provided below the bottom.

The prize-winning device 1 opens an opening 8 in a substrate 7 attached to the surface of the game board 2, and opens a prize opening 9 in the surface of the substrate on the opening 8.
A movable wing piece 11 functioning as a movable ball receiving member is rotatable by a support shaft 12 on the side edge of the opening 8 located below the left and right ends of the armor section 10. A special winning opening 14 defined by a partition plate 13 near the lower edge of the opening 8
And the front general winning opening 15 is protruded, and a case is
By providing 16, a concave chamber 17 including a portion surrounded by the armor section 10, the two movable wing pieces 11, the special winning opening 14, and the front general winning opening 15 is formed, and the inside of the concave chamber 17 is formed inside. The movable body 18 is provided to be vertically movable. A continuation switch 19 faces the special winning opening 14 described above.

On the back side of the case 16, a solenoid that drives the movable wing piece 11
A pin 25 of a crank member 24 fixed to the rear end of each support shaft 12 is loosely fitted into a hole 23 of an operation plate 22 fixed to a plunger 21 of the solenoid 20. Therefore, both movable wing pieces 11
Indicates that the solenoid 20 is in a state where the solenoid 20 is demagnetized.
As shown by the dashed line in FIG. 15 due to the bias of the spring 26 and the like, the first state is disadvantageous to the player who does not allow the ball that rises and flows down the inside of the game part 4 to flow into the concave chamber 17, When the solenoid 20 is excited by energization from the control device, both movable wing pieces 11 move as shown by solid lines in FIG.
To a second state that is advantageous to the player who flows into the player.

Further, in the illustrated embodiment, a partition having a clearance space 27 for the internal movable body 18 at the center in the width direction is provided at a rear portion of the concave chamber 17.
The rear of the partition wall 28 is defined as a left and right rear general winning opening 29. The inclined bottom surface of the concave chamber 17 is located below the escape space 27.
30 is extended and an extension piece 31 is provided.
The ball which did not flow into 29 can be rolled forward.

A drive mechanism for moving the internal movable body 18 up and down is provided on the back side of the case 16. This drive mechanism is a guide rod that extends through the support rod 32 extending from the rear end of the internal movable body 18 into the elongated hole 33 on the back of the case 16 and extends up and down of the internal movable body 18.
34 penetrates through the ceiling surface and the inclined bottom surface 30 of the concave room 17, and the case 16
The upper end of the connecting rod 35 is rotatably fixed to the rear end of the supporting rod 32 protruding from the rear surface of the support rod 32, and the knitting center shaft 38 of a rotary plate 37 fixed to the output shaft of a motor 36 with a speed reducer. The lower end of the connecting rod 35 is rotatably fixed, a notch 39 is provided around the rotary plate 37 as a positioning identification portion, and a photo sensor 40 is exposed as a detecting means. The turntable 37 is always stopped in a state where the photosensor 40 detects the notch 39a at the reference stop position. Accordingly, the inner movable body 18 maintains the first state in which the inner movable body 18 stops at a position slightly higher than the ends of both movable blade pieces 11 in the second state, as shown by the solid line in FIG. In the first state, since the distance between the inner movable body 18 and the end of the movable wing piece 11 is smaller than the diameter of the sphere, when the ball flowing down in the game section 4 falls on the movable wing piece 11 However, the ball does not directly enter the special winning opening 14 or the front general winning opening 15 and once flows down onto the ball mounting portion 41 extending to the left and right of the internal movable body 18, and then flows to the upper edge of the partition wall 28. It often falls on the provided inclined piece 28 'and flows into the rear general winning opening 29 provided behind the partition wall 28, but falls on the inclined bottom surface 30 from the escape space 27 provided between the left and right partition walls 28. Then, the player may enter either the special winning opening 14 in the front or the general winning opening 15 in the front. In other words, in the reference state where the inner movable body 18 is located at the middle stage,
The inner movable body 18 functions as an obstacle, so as to prevent a ball flowing down on the movable wing piece 11 from directly entering the special winning opening 14.

Further, the prize winning device 1 will be briefly described along with a game with reference to the flowchart of FIG.
When the ball fired by the player flows into the first starting port 5a or the second starting port 5b, the movable wing piece 11 opens once or twice, and flows into the concave chamber 17 while the movable wing piece 11 is open. The special game is started on condition that the dropped ball further flows into the special winning opening 14. In the special game, the control device is the solenoid 20 of the winning device 1.
The movable wing piece 11 is opened and closed by exciting a predetermined number of times (for example, 18 times) at predetermined time intervals, and a predetermined number of times (for example, 10 pieces) ) Is defined as one cycle, and the ball can be updated to the next cycle on condition that the ball enters the special winning opening 14 during this cycle. It should be noted that the cycle can be updated up to a predetermined number of times (for example, 8 cycles).

Then, when the movable wing piece 11 opens and closes, for example, five times, the motor 36 is operated by the command of the control device to rotate the rotary plate 37. When the turntable 37 rotates, the internal movable body 18 rises by the crank action of the shaft of the turntable 37 and the connecting rod 35, and when the turntable 37 rises to the top dead center, the photo sensor 40 detects the notch 39b and controls the control unit. , The motor 36 stops operating. When the internal movable body 18 rises in this way, the distance between the ends of both movable wing pieces 11 and the internal movable body 18 becomes much larger than the diameter of the sphere, as shown by the chain line in FIG. Therefore, when the ball flowing down in the game section 4 falls on the movable wing piece 11, the ball often falls directly from the lower end of the movable wing piece 11 into the special winning opening 14 or the front general winning opening 15. . However, some of the balls are guided rearward, flow into the rear general winning opening 29, or fall to the inclined bottom surface 30.

When the ball enters the special winning opening 14, the continuation switch 19
Turns on and sends a signal to the control unit, and the control unit
The rotating plate 37 is reversed by reversing 36. When the turntable 37 reverses (for example, counterclockwise in FIG. 19), the turntable 37
The internal movable body 18 is lowered by the crank action of the connecting shaft 35 and the connecting rod 35, and the photo sensor 40 detects the notch 39 ″ serving as the sub-identifying part, and within the predetermined time, the next notch 39a serving as the main identifying part.
Is detected, the notch 39a is recognized as the origin, and the motor 36 is stopped. Therefore, the internal movable body 18 stops at the middle stage in the reference state. In addition, according to the method of the present invention, the origin can be detected by rotating the rotating plate 37 in the forward direction, and the internal movable body 18 can be detected.
Can be stopped exactly at the middle stage.

On the other hand, when the movable wing piece 11 opens and closes ten times without the ball flowing into the special winning opening 14, the control device operates the motor 36 to rotate the rotary plate 37 again. When the turntable 37 rotates, the internal movable body 18 descends due to the crank action between the shaft of the turntable 37 and the connecting rod 35, and the photo sensor 40 detects the notch 39c at the bottom dead center and sends a signal to the control device. , The motor 36 stops operating, and the internal movable body 18 stops at the lower stage. In this state,
Since the distance between the ball mounting portion 41 of the inner movable body 18 and the inclined bottom surface 30 is smaller than the diameter of the ball, the ball is locked and accumulated at the rear edge of the ball mounting portion 41.

Then, when the overflowing ball flows into the special winning opening 14 or when the movable wing piece 11 opens and closes 15 times, the motor 36 is rotated again to rotate the rotating plate 37, and the internal movable body 18 is raised. Then, the photo sensor 40 detects the notch 39 'serving as the sub-identifying section, and subsequently detects the notch 39a serving as the main identifying section.
Stops at the middle stage. At this time, the ball held by the internal movable body 18 is released, rolling on the inclined bottom surface 30 and the special winning opening 14
Or flow into the front general winning opening 15. The movable wing piece 11
If you do not win the special winning opening 14 during the 18 opening times, 18
The special game ends when the opening and closing of the round ends or when ten balls flow into the concave chamber 17.

In this special game, if the special winning opening 14 is not won, the internal movable body 18 is sequentially stopped in the upper stage, the lower stage, and the middle stage according to the number of times the movable wing piece 11 is opened and closed. If there are no two winning balls in the recessed room 17 between the end of opening and closing 10 times after the end, such as setting to end the special game without waiting for the end of opening or closing 18 times or the end of 10 counts,
A gateway may be provided in the game.

As described above, according to the present invention, it is possible to stop the turntable 37 at a predetermined position regardless of the rotation direction of the turntable 37.

Next, the above-mentioned game will be described from the control means side. In FIG. 21, reference numeral 42 denotes a central processing unit (hereinafter referred to as a CPU) including a RAM and the like used for data calculation and the like.
43 is a clock circuit for supplying a predetermined pulse to the CPU 42, 44
Is a reset circuit that resets the CPU 42, 45 is a power reset circuit that initializes the CPU 42 and the like when the power is turned on, 46 is a frequency divider circuit that supplies a desired pulse to the reset circuit 44, and 47 operates the CPU 42. (Hereinafter referred to as PROM) in which programs and data are stored, 48 is an input / output control device, 49 is a continuous winning ball detection circuit,
50 is a start winning ball switch circuit, 51 is a 10 count detection circuit, 52 is a solenoid drive circuit, 53 is a stop position detection circuit,
54 is a motor drive circuit.

When the power is turned on, the CPU 42 performs initial settings such as clearing of the RAM and checking of each part. If there is no abnormality, the CPU 42 controls the game as described above and performs a fraud prevention function.
For example, when a disconnection or a short circuit occurs in the 10-count detection circuit 51, the start ports 5, the continuation switch 19, the driving solenoid 20, and the like are stopped.

Further, the CPU 42 activates the lamp drive circuit 55 to turn on or blink an indicator lamp formed of, for example, a lamp or the like, and also activates the electronic sound circuit 56 to generate a sound effect indicating the entry of the ball, and the starting port 5. The ball entry is displayed visually and audibly to the player.

Further, when a ball wins in the special winning opening 14 provided in the winning device 1, the continuation switch 19 is turned on, and a continuation signal is outputted from the continuation winning ball circuit 49 to the CPU 42. In this case, the game is shifted to a special game, but also at this time, the lamp drive circuit 55 and the electronic sound circuit 56 are driven to turn on and blink the display lamp and generate a sound effect to excite the excitement of the game.

Then, the LED drive circuit 57 drives the continuation number display lamp 58 for displaying the number of cycles of the special game and the 10-count display lamp 59 for displaying the number of balls that have won the recessed room 17 of the prize device 1.

In addition, 60 is a starting port switch facing each starting port 5 ..., 61
