Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a variable winning device for a pachinko machine, and in particular is adapted to change the winning rate.

This type of variable winning device changes the winning equipment on the game board in conjunction with the winning of a game ball in a specific winning opening to make it easier to win, thereby making pachinko games more interesting and not monotonous. It is used to increase For example, what has been conventionally used is to arrange so-called tulips as multiple variable prize winning devices on the game board, and to open these chulips all at once when a game ball enters a specific prize opening. There is a game board in which the winning rate on the game board is increased, and each ticket is closed individually each time a game ball wins a prize. However, such a configuration inevitably gives a sense of monotony, and the emergence of a variable prize winning device that can overcome this monotony has been awaited.

The present invention attempts to propose a variable winning device that can sufficiently satisfy such demands, and when a game ball wins a particular winning device, the opening of the winning opening of the variable winning device is repeatedly opened and closed. This is intended to further enhance the interest of pachinko games.

Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

Figures 1 to 3 show the structure of the variable winning mechanism of the variable winning machine.As shown in Figure 2, the surrounding collar 1 is applied to the game board 2 of the pachinko machine and screwed as shown in Figure 1. It is screwed down by 3. A specific winning part 4 is formed on the upper part of the variable winning mechanism, and the winning game balls in this specific winning part 4 are detected by a winning detector formed of, for example, a micro switch, provided in a guide gutter 4A extending to the rear of the game board 2. 5. Further, fixed winning portions 5L and 5R are provided at the lower left and right portions of the specific winning portion 4.

Further, a variable winning device 6 is provided at the lower center of the fixed winning portions 5L and 5R.

The variable prize winning device 6 has a U-shaped receiving frame 7 that opens diagonally upward.
, and a winning window 8 is formed below the center thereof.
In this way, the game balls that enter the prize opening between the fixed winning parts 5L and 5R and the receiving frame 7 from the left and upper right enter the winning window 8, and are placed in the guide gutter 9 extending rearward from this window 8. A prize winning detector formed of, for example, a micro switch]0 is used to detect the winning prize. The winning opening located above the receiving frame 7 is provided with movable gate plates ]]L and 1]R for changing the opening degree. The moving gate plates 11L and 11R are connected to the substrate 1.
[Guiding holes extending in the left-right direction in 2] are rotatably attached to pins 15 planted toward the front of movable pieces 14L and 14R, which are slidably mounted in 3L and 13R, The lower end hangs down so as to slide into sliding contact with the obliquely upwardly rising portion of the receiving frame 7.

Therefore, the moving pieces 14L and 14R are connected to the through holes 13L and 13.
When R is slid outward to the left and right, the moving gate plates 11L and 1
1R is designed to gradually open upward (
Figure 1 (dashed line). An engagement pin 2] extends from the rear portion of the board 12 of the movable pieces 14L and 14R, and contacts the crank portions 23 of the left and right crank gears 22L and 22R from the outside.

The crank gears 22L and 22R consist of a tarunk portion 23 extending in the vertical direction and a gear portion 24 formed at the upper end thereof. For example, a pin 26 of a pin disk 25 engages with the gear portion 24 of the left crank gear 22L. ing. This pin disk 25
For example, the pin 26 is placed at an angle of 30° as shown in FIG.
is planted and rotated by the motor 27 (Fig. 2) in the clockwise direction of the arrow 28 in Fig. 3, the left crank gear 22L
Rotate counterclockwise. On the other hand, this left crank gear 2
The gear part 2 of the right crank gear 22R is attached to the gear part 24 of the 2L.
4 engages, and this causes the left crank gear 22L to shift to the third position.
In the figure, when the right crank gear 22R rotates counterclockwise, the right crank gear 22R rotates clockwise in synchronization with the rotation, and thus the pin 2 is in contact with the outside of the crank gears 22L and 22R.
Moving pieces 14L and 14R by pushing 1 outward
is moved outward along the through holes 13L and 13R.

Protrusions 30 are provided on the moving pieces 14L and ]4R (the third
A restoring spring 3] is stretched between the projecting pieces 30, and the movable pieces 14L and 14R are pulled inward by the spring 31, so that the left and right crank gears 22L and 22R are respectively Rotationally biased in clockwise and counterclockwise directions (FIG. 3).

On the other hand, the pin disk 25 has three pins 26 planted at angular intervals of 30 degrees, and a vacant space 32 where no pins are planted is provided at an adjacent corner position of 30 degrees. Therefore, when the pin disk 25 is rotated by the motor 27, the three pins 26 engage with the left crank gear 22L and the left and right clunter gears 22L.
and 22R are rotated outward against the spring 31 while moving pieces 14L and ]4R are moved outward, but when the space 32 of the pin disk 25 faces the left crank gear 22L, Since rotational force is no longer applied to the left and right crank gears 22L and 22R, the movable pieces 14L and ]4R are restored inwardly by the spring 3]. The restored state is thus obtained, but then the pin disk 25 rotates and the next three pins 26 engage with the gear portion 24 of the left crank gear 22L, causing the left crank gear 22L and the right crank 22R to resist the spring 31. By rotating the moving pieces 14L and 14R outward again, the moving pieces 14L and 14R are moved outward again.

Thereafter, while the motor 27 is being driven, the moving piece 1 is moved in the same manner.
4L and 14R are alternately moved outward or inward. When the movable pieces 14L and 14R alternately move outward or inward in this way, the movable plates 1]L and 11R expand in the left-right direction or are pinched inward (Fig. 1), and therefore the game The state in which the winning rate of the ball is high and the state in which the winning rate is low are alternately changed, and this converted state differs depending on the rotational speed of the disc 25, that is, the driving state of the motor 27. For example, if the disk 25 is rotated quickly by driving the motor 27 to shorten the time for one rotation, the above-mentioned high and low winning rate states will be repeated at appropriate intervals, but the driving of the motor 27 will cause the disk 25 to become extremely If the rotation is slow and the time for one rotation is lengthened, the left and right movable plates 1]L, llR will expand in the left and right direction, and the high winning rate will continue for a long time. Therefore, if the driving state of the motor can be set arbitrarily, the variable winning mechanism will be rich in variety. Note that 34L and 34R are decorative plates attached to the movable pieces 14L and ]4R. The above-described variable winning mechanism is driven and controlled by a drive control circuit 35 shown in FIG. The drive control circuit 35 receives the output from the winning detector 5 of the specific winning part 4 as a trigger input, starts rotating the motor 27, and activates the winning detector of the variable winning tool 6]
The output from 0 is received as a stop signal for the motor 27.

However, this motor 27 is made to stop when the number of winning game balls to the variable winning device 6 reaches a predetermined number, and this stopping number of winnings is selected at the timing of winning the game balls to the specific winning part 4. Ru.

That is, the drive control circuit 35 is provided with a stop number selection signal generation circuit 36, which outputs a stop number selection signal S1 or S8 of, for example, ``1'' or ``8'' to the preset down counter 37, and presets the preset down counter 37. The count counter 37 is set to ``1'' or ``8''. The stop number selection signal generation circuit 36 alternately generates the stop number selection signal S1 or S8 of "1" or "8", and the time ratio is manually controlled by the winning probability changeover switch 38 connected to the generator 36. It can be switched with . Specifically, as the generation circuit 36, an RC rectangular wave oscillation circuit is used, and the logic level is alternately "
Create a signal that becomes "1" or "0", and convert this signal and the inverted signal obtained by inverting it by an inverter to "1", respectively.
The stop number selection signal S1 and "8" are given to the preset down counter 3''7 as the stop number selection signal S8, and the time constant of the RC rectangular wave oscillation circuit is changed via the winning ratio switching switch 38. According to "1" and "
8'' may be applied that changes the time ratio of the stop number selection signals S1 and S8. The preset down counter 37 outputs the output from the winning detector 5 of the specific winning section as a preset command signal to a pulse generating circuit 40 having a differentiating circuit configuration, for example.
A pulse generated at the rising edge of the output of the winning detector 5 is received via the presetting gate circuit 41.

In addition to this, the preset down counter 37 supplies the output as a down count input signal when the winning detector 10 of the variable winning prize tool is closed to, for example, a pulse generating circuit 42 having a differential circuit configuration, and outputs the output at the rising edge of the output of the winning detector 10. The pulse generated by the down-counting gate circuit 43 is received via the down-counting gate circuit 43.

However, the contents of the preset down counter 37 are "
It generates a "0" detection signal ZD, which becomes logic "0" when the signal is "0", and gives this to the down-count gate circuit 43 as a close signal, and inverts it by the inverter 44 to provide an open signal to the preset gate circuit 41. give as. As a result, the preset down counter 37 changes its contents to "0".
'', the gate 1 circuit 41 is opened to receive a preset pulse, and the output S1 or S3 of the generating circuit 36 is preset. At this time, the "0" detection signal ZD becomes logic "1", thereby closing the preset gate circuit 41 and opening the down-counting gate circuit 43 to count down the contents of the preset down counter 37 by "1" from the preset value. I'll go. Then, when the content of the preset down counter 37 becomes "O", the gate circuit 43 is closed and the gate circuit 41 is opened to wait for the arrival of the next preset signal. The “0” detection signal ZD of the preset down counter 37 is further applied to a discrimination circuit 46.

This discrimination circuit 46 applies a drive control signal to the drive circuit 47 of the motor 27 to drive the motor 27 when the "O" detection signal ZD is not at logic "O". At the same time, the output of the discrimination circuit 46 is applied to an electronic sound generator 48, which generates a pseudo sound for the player. In this way, the drive circuit 47 that drives the motor 27 stops the motor 27 when the drive control signal is no longer obtained in the discrimination circuit 46, but at this time the pin disk 25 connected to the output shaft of the motor 27 stops.
The motor 27 is continued to be driven until the empty position 32 is opposed to the crank gear 22L, thereby stopping the motor 27 with its rotating shaft at a predetermined fixed position.

For this purpose, a protrusion 48'' is provided on the back surface of the pin disk 25 as shown in FIG. 4, and this protrusion 48'' is connected to a stop position detector 50 (
When the micro switch (consisting of a microswitch) is operated, the pulse generated by the pulse generation circuit 51 is given to the motor drive circuit 47 as a stop signal based on its detection output, and the motor 2 is
Stop 7. On the other hand, the contents of the preset down counter 37 are converted into a display signal by the decoder 55, and then
The number of winnings is displayed on the winning number display 56.

In this embodiment, the winning number display 56 is composed of light emitting diodes forming seven segments, and is arranged in the center of the variable winning mechanism as shown in FIGS. 1 to 3. Note that 57 is a lens. Also, preset down counter 3
Inverter 44 formed by inverting the “O” detection output ZD of No. 7
The output is given to a random display signal generation circuit 58, which generates a "1" or "8" display signal S at this time.
By alternately applying ll or Sl8 to the decoder 55 at a random time ratio, the number "1" or "
8'' is randomly displayed, and thus, when no game ball has won in the specific winning section 4, the display 56 is decoratively lit.

In the above configuration, when the variable prize winning device is in the non-operating state, the content of the preset down counter 37 of the control circuit 35 is “
0" state.

Therefore, the motor 27 is stopped, and the variable prize winning tool 6 is in a state where the moving pieces 14L and ]4R are drawn inward by the spring 31 and the winning rate is the lowest. At this time, by driving the random display signal generation circuit 58 via the inverter 44, the display 56 repeatedly displays the numbers "1" or "8" randomly via the decoder 55.
At this time, the down-count gate circuit 43 is maintained in a closed state, and the preset gate circuit 41 is maintained in an open state.

Therefore, the game ball wins in the variable winning device 6 and the winning detector 10
When operated, the down-count pulse generated in the pulse generating circuit 42 is blocked by the gate circuit 43, and thus the prize balls are ejected by a separate prize ball ejecting device as in a normal pachinko machine. In this state, when a game ball wins in the specific winning part 4 and the winning detector 5 operates, the preset input pulse generated in the pulse generating circuit 40 is given to the preset down counter 37 through the gate circuit 41, and the output of the generating circuit 36 is The preset down counter 37 is preset.

At this time, the probability of presetting the numerical value "1" or "8" is determined by the ratio of the generation time of the "1" or "8" stop number selection signal S1 or S8 of the generating circuit 36. At this time, the content of the preset down counter 37 becomes 51" or 8, so the preset gate circuit 41 is closed and the operation of the random display signal generation circuit 58 is stopped. is displayed on the display 56.

In this way, the player can know that the period during which the variable prize winning tool 6 continues to operate is until the game ball makes an individual prize of "1" or "8".

On the other hand, the logic “1” of the preset down counter 37 is “0”.
The detection signal ZD is discriminated by the discrimination circuit 46, and the motor 27 and the electronic sound generator 48 are driven.

Therefore, the variable prize winning device 6 is a moving piece] 4L and 14R are opened and closed via the pin disk 25, and thus the winning rate fluctuates even though the winning rate is high, and as a result, the player obtains a certain profit. However, it is possible to continue playing the game while enjoying the fluctuation of the profit rate. In this state, every time a game ball wins in the variable winning device 6, the pulse generating circuit 4
The down-count panoresque that occurs at step 2 causes the contents of the preset down counter 37 to count down, and the change is displayed on the display 56.

In this way, when the content of the preset down counter 37 eventually reaches "0", the output of the discrimination circuit 46 causes the motor 2 to
A stop command is given to the drive circuit 47 of No. 7.

However, the motor 27 continues to drive until the stop position detection switch 50 is activated, and then stops at the normal position. On the other hand, the gate circuit 43 is closed, the gate circuit 41 is opened, and the random display signal generation circuit 36 starts operating to cause the display 56 to display a random display. Thus, it returns to its original state. As described above, according to the present invention, it is possible to realize a pachinko machine in which the winning rate is further increased and fluctuates by changing the opening/closing of the winning opening of the variable winning prize device when a game ball wins in a specific winning section. .

Therefore, by displaying the contents of the preset down counter 37 on the display 56 disposed on the game board as in the case of the above-mentioned embodiment, the player can easily check the current status of the pachinko machine. can be grasped. Furthermore, if the ratio of the generation time of each selection signal generated by the stop number selection signal generation circuit 36 can be changed, the winning rate of the pachinko machine can be easily adjusted.

In the above description, the number of stop number selection signals generated by the stop number selection signal generation circuit 36 is two, but the number of stop number selection signals may be one, or three.
The above may be caused to occur alternately and sequentially,
Further, a numerical value other than "1" or "8" may be generated.
