In order to achieve the above object, the present invention uses a motor as a drive source for moving the moving winning portion, and
By engaging an engaging pin on the rotating plate rotated by this motor and providing an engaging portion that engages with this engaging pin on the moving winning portion, the engaging pin engages during rotation of the rotating plate. The moving prize portion is moved linearly by pressing the portion, and the signal portion is formed on the rotating plate, and the switch device is switched by this signal portion each time the rotating plate makes one rotation. It is configured to detect the round trip electrically and accurately.

[First embodiment]

In FIG. 6 showing an example of a pachinko machine using the present invention, a pachinko ball 2 hit by an operation of a ball operation unit 1 flows down in a board surface 3 from top to bottom. In the process of this downflow, the pachinko ball 2 changes its downflow path variously by an obstacle nail, a windmill, etc. (not shown), and the safe hole 4,
Win the tulip 5 or the attacker 6 opened depending on the situation, or collect it in the out hole 7.
As will be described later, the moving winning portion 1 is provided at the substantially center of the board surface 3.
A winning ball device 11 including 0 is provided, and the winning ball device 11 starts its operation when a prize is generated in the safe hole 4.

As shown in FIG. 1, the winning ball apparatus 11 is formed by a base 13 attached to the board surface 3 so that its front surface 13 a is flush with the board surface 3, and protruding forward of the board 13. Elliptical protrusion 14 and arcuate protrusion 15
The movable winning portion 10 that is movable in the left-right direction below the protrusions 14 and 15, the prize receiving portion 16 provided below the moving winning portion 10, and the prize receiving portion 16 It has a left winning opening 17, a right winning opening 18, and a V winning opening 20 for pachinko balls.

On the surface of the elliptical projecting portion 14, there are provided light emitting diode rows 22 (upper row) and 23 (lower row) arranged in five rows in upper and lower rows.

In the normal state, the moving winning portion 10 is at the position shown by the solid line in FIG. 1, and the pachinko ball 2 flowing down from above the winning ball device 11 is distributed to the left and right by the projecting portions 14 and 15, and the moving winning portion is moved. It is not accepted by part 10. However, the mobile prize unit 10 will be described later.
It is possible to move between the right position indicated by the alternate long and short dash line in FIG. 1 and the target left position. For example, in the right position, the right side of the moving winning portion 10 is rightward of the arc-shaped protruding portion 15. Since it projects in one direction, the pachinko ball flowing down from above is
From this part, it will flow into the moving winning part 10.
An opening 24 is formed on the lower surface of the moving prize portion 10 for dropping the pachinko ball received by the moving prize portion 10 to the prize receiving portion 16.
The pachinko ball that entered is the left winning opening 17, the right winning opening 18,
Alternatively, one of the V winning openings 20 will be awarded.

The movable winning portion 10 penetrates through a horizontally long slot 25 formed on the board surface 3 and extends to the back surface side of the board surface 3
Book pins 27 and 28 are planted. This pin 27,
As shown in FIG. 2, which illustrates the back surface side of the winning ball device 10, 28 are fixed to the left and right sides of the cross-shaped slide member 30 on the back surface side of the board surface 3, respectively. Therefore, when the slide member 30 is moved left and right, the pin 2
The moving prize portion 10 moves left and right integrally with the slide member 30 through the slots 7, 28 and the slot 25.

As shown in FIG. 3, a motor 32 is attached to the boss 31 provided on the back surface of the base 13 of the winning ball device 10.
The support plate 33 to which is fixed is screwed. The drive shaft 34 of the motor 32 is directed toward the center of the slot 25, and a sleeve 38 is fixed to the drive shaft 34. An arm 35 and a disk 36 are fixed to one end side of the sleeve 38, and a tip portion of the arm 35 further includes
A pin 40 that rotatably supports the roller 39 is planted.

As shown in FIG. 4, the roller 39 is engaged in a vertically long engagement slot 42 formed in the slide member 30. The engagement slot 42 is positioned so as to overlap the slot 25 formed in the base 13 in the central portion thereof at right angles. The length of the engaging slot 42 is slightly larger than the diameter of the circle that is the locus of the pin 40 when the arm 35 rotates. Further, a concave portion 43 is formed in a part of the outer circumference of the rotary plate 36, and the tip end of the microswitch 44 having a spring property is fitted therein.

According to the circuit shown in FIG.
It is operated as follows. That is, when the pachinko ball 2 wins the start hole 4 (FIG. 6) during play, the start winning ball detection unit 50 including a well-known micro switch or photo sensor detects this and activates the start signal generation circuit 51. . As a result, the start signal generation circuit 51 drives the motor 32 via the drive circuit 52.

When the motor 32 is driven, the arm 35 and the rotary plate 36 rotate, so that the pin 40 and the roller 39 planted in the arm 35 move counterclockwise along a circle centered on the drive shaft 34 of the motor 32. Moving. Thereby, the slide member 30
Will move to the left, and the moving winning part 10 will also move to the left via the pins 27 and 28. Then, while the arm 35 makes one rotation, the moving winning portion 10 makes one reciprocation from side to side. When the rotary plate 36 makes one rotation, the micro switch 4
4 detects the recess 43 and turns off the motor 32, so that the motor 32 is stopped after one rotation. In addition, timer 5
3 is provided to invalidate the OFF signal from the micro switch 44 for a predetermined time when the motor 32 is started.

In this way, when the pachinko ball 2 is received in the moving prize portion 10 while the moving prize portion 10 makes one round trip, the pachinko ball 2 falls from the opening 24 to the prize receiver 16, and the left winning opening 17 and the right winning opening are provided. Win either 18 or V winning opening 20. When the left winning opening 17 or the right winning opening 18 is won, a prize ball payout device (not shown) is activated by detection signals from publicly known winning ball detecting units 55 and 56 provided at the respective winning openings. Then, a predetermined number of prize balls are paid out.

As described above, while the mobile winning unit 10 makes one round trip, V
When a winning is generated at the winning opening 20, the V winning ball detection unit 58
Is activated, the prize balls are paid out, and the counter 60
The count value "10" is set up. At the same time,
The V winning ball detection unit 58 stops the subsequent detection operation of the start winning ball detection unit 50. If the count value of the counter 60 is other than "0", an operation signal is supplied from the counter 60 to the start signal generating circuit 51, so that the motor 32 is driven and the moving winning part 10 starts reciprocating again.

The reciprocating movement of the moving winning portion 10 thus restarted is performed until the count value of the counter 60 is returned to "0", so that the reciprocating movement is performed 10 times. It should be noted that the micro switch 44 is turned off after each rotation of the rotary plate 36.
A signal is detected, this signal is input to the counter 60 as a subtraction pulse, and the counter 60 is also reset to "0" after the moving winning part 10 has performed 10 reciprocating movements. At this point, the operation stop of the start winning ball detection unit 50 is released.

In this way, while the mobile prize unit 10 makes 10 reciprocating movements, some pachinko balls 2 enter there, and these randomly enter the winning openings 17, 18 and 20. The numbers of winnings at the winning opening 17 and the right winning opening 18 are separately counted by the counters 62 and 63 connected to the left winning ball detecting unit 55 and the right winning ball detecting unit 56, respectively. The count values of the counters 62 and 63 are sequentially displayed on the light emitting diode rows 22 and 23 via the display circuits 64 and 65.

The counters 62 and 63 include comparator circuits 66 and 66, respectively.
67 is connected to each of the counters 62 and 63.
And the count value "5" set in the counter 68 is compared. When one of the comparison circuits detects the coincidence, the operation of the other counter 62 or 63 is stopped.

When the number of the pachinko balls that have won the left winning opening 17 reaches five first and the count values of the counter 62 and the counter 68 match, the switching circuit 56 is sent by the match signal from the comparison circuit 66.
Is switched to operate, and the detection signal from the start winning ball detection unit 50 is provided to the counter 60 as a signal for setting up the count value of the counter 60 to "10". Therefore, next time you win the start hole 4,
The mobile prize unit 10 is the same as when the V prize hole 20 is won.
It will be reciprocated 10 times.

On the other hand, when five prizes are previously generated in the right winning opening 18 while the moving prize unit 10 is reciprocating ten times, the switching circuit 5 is caused by the coincidence signal from the comparison circuit 67.
6 outputs the detection signal from the start winning ball detecting unit 50 as the operation start signal of the V winning ball detecting unit 58. Therefore, as described above, the moving winning unit 10 makes one reciprocating movement. Stop later. Of course V in the meantime
When the winning is made in the winning opening 20, the moving winning unit 10 further makes 10 reciprocating movements. The V winning ball detection unit 58
Is also used as a signal for resetting the count value remaining in the counters 55, 56 to "0".

[Second Embodiment] FIGS. 7 and 8 show a second embodiment of a winning ball device to which the present invention is applied.
An example is shown. In this embodiment, the front surface of the base plate 71 of the winning ball device is flush with the board surface 3 (see FIG. 1) of the pachinko machine, and a box-shaped accommodating portion 72 is continuously provided in the back of the board surface 3. . The moving prize portion 70 is housed in the housing portion 72 so as to be movable in the front-rear direction. An opening 76 is formed on the upper surface of the moving winning portion 70, and the pachinko ball flowing in from the opening 76 flows down from the opening 77 at the bottom.

Then, when the moving winning part 70 is at the position shown by the solid line in FIG. 7, the pachinko ball that has entered from the winning opening 75 falls directly in front of the moving winning part 70 and is returned to the board surface 3 again. However, when the pachinko ball wins the safe hole 4 (Fig. 6), the moving winning part 7 is moved by the moving mechanism described later.
Since 0 moves toward the board 3 and moves to the position shown by the chain double-dashed line in FIG. 7, the pachinko ball falling from the winning opening 75 flows into the moving winning portion 70 from the opening 76. Then, it is discharged to the winning ball passage 73 through the opening 77.

The moving mechanism for moving the moving winning portion 70 is a motor 78 fixed to the upper surface of the housing portion 72, its drive shaft 7
It is composed of a rotary plate 80 fixed to 9, a pin 82 planted in the rotary plate 80, and a guide member 83 fixed to the upper surface of the moving winning portion 70. An engagement groove 85 is formed in the guide member 83, and the pin 8 is formed in the engagement groove 85.
2 is inserted. The engaging groove 85 is provided in the moving winning portion 7
0 is extended in a direction perpendicular to the moving direction of the pin 8 and the length thereof is obtained by rotating the rotary plate 80.
The diameter is slightly larger than the diameter of the locus circle of 2.

Slots 90 are formed on both side walls of the receiving portion 72,
Inside the slot 90, a horizontally long protrusion 92 formed on both side walls of the moving winning portion 70, and a roller 94 rotatably supported in the protrusion 92 are provided. When the moving winning part 70 moves in the front-rear direction, the rollers 94 roll while contacting the upper and lower surfaces of the slot 90, so that the moving winning part 70 can be smoothly moved. Furthermore, when the mobile prize unit 70 moves, the mobile prize unit 7
Since the guide piece 95 formed so as to project on the lower surface of 0 slides on the guide projection 96 provided on the lower inner wall of the housing portion 72, the moving winning portion 70 is moved in the front-back direction without tilting.

In the winning ball device configured as described above, the motor 78 is started to drive when the pachinko ball enters the safe hole 4. As a result, the rotary plate 80 rotates along a plane of rotation perpendicular to the plane of the drawing, and the pin 82 moves circularly with it. By the circular movement of the pin 82, the inner wall of the engaging groove 83 is pushed by the pin 82, so that the moving winning portion 70 is pushed forward (to the left in FIG. 7). Therefore, the moving winning portion 70 moves to the position where the winning is easily obtained, which is indicated by the chain double-dashed line in FIG.
All the pachinko balls from the winning hole 75 are processed as winning balls.

When the drive of the motor 32 is continued and the rotary plate 80 returns to the original position even after one rotation, the micro switch 96 detects the concave portion 97 provided on the outer periphery of the rotary plate 80 and drives the motor 78. Since it is stopped, the moving winning part 70 makes one reciprocating movement in the front-back direction and stops. In the normal stop state, the micro switch 96 is off, so that the motor 78 is started, the OFF signal from the micro switch 96 is invalidated for a predetermined time from the moment when the prize is generated in the safe hole 4. The conversion is the same as in the first embodiment.

In the first and second embodiments described above, the engaging slot 42 and the engaging groove 85 are both linear, but they may be slightly curved or bent. It is also possible to change the moving speed of the moving prize unit during the moving process. In addition, the moving winning portions 10, 70 are biased in one direction, and the engaging slot 42
Alternatively, if one side surface of the engaging groove 83 is brought into contact with the pins 40 and 82, an extended engaging protrusion may be formed instead of the engaging slot 42 or the engaging groove 83. Further, in the second embodiment, it goes without saying that the engaging groove 85 may be directly formed on the upper surface of the moving winning portion 70.

[Effect of device]

As described above, in the present invention, the rotating plate having the engaging pins implanted therein is driven by the motor, and the moving winning portion is linearly moved back and forth by the movement of the engaging pin while the rotating plate makes one rotation.
Moreover, since the one reciprocating movement is electrically detected by the switch device via the signal portion provided on the rotary plate,
The interlocking mechanism for linearly moving the moving winning portion is simplified, which is advantageous in terms of the number of parts and the installation space, and it is possible to reliably confirm the operation of the moving winning portion. Further, in order to have a change in the moving speed of the moving winning portion, it is only necessary to change the shape of the engaging portion, and it is not necessary to change other configurations, which is convenient when changing the interest. .
