A case is shown in which a pair of arm members and at least one ball receiving piece are opened based on the output of step 4).

Next, with reference to FIGS. 1 to 6B, FIGS. 8 and 9, the specific circuit configuration and operation of FIG. 8 will be described.

First, the operation when a ball enters the winning hole 32 will be explained. In the initial state, when the power is turned on, the output of the initial reset circuit 69 is applied via the priority determining circuit 62 to the reset input terminals of the monostable multis 613a to 613d included in each of the holding circuits 61a to 61d. stable multi 613a
~613d is reset to the initial stage. Thereafter, when a ball enters the winning hole 32, it is detected by the ball detection switch 22. The output of the ball detection switch 22 (low level) is provided as one input of a NAND gate 612a via a chattering prevention circuit 611a. The NAND gate 612a has the output (high level) of the monostable multi 613a as the other input.
is given, so the chattering prevention circuit 6
During the period when the output of 11a is at a low level due to the closure of the ball detection switch 22, a high level is derived to operate the monostable multi 613a. Accordingly, the monostable multi 613a at time t1
to the output Q for a certain period of time T1 (for example, 4.5 seconds)
A high level is derived and given to the NOR gate 641. Noah gate 641 is monostable multi 613
During the period when the output Q of a is at a high level, a low level is derived and the NAND gate 643 and the NOR gate 63
Give to 3. At this time, since the output Q of the monostable multi 642 is at high level, the NAND gate 64
3 derives a high level for a certain period of time T1 and operates the driver 644. The driver 644 is of an open collector type, for example, and keeps one end of the solenoid 42 at ground potential while its input is at a high level. This allows the power supply (+
30V) flows through the solenoid 42, causing the solenoid 42 to be electrically energized. Therefore, as described above, the pair of arm members 36a, 36b rotates outward.

At time t2 after a certain period of time T1 has elapsed from time t1, when the output Q of the monostable multi 613a becomes low level, the output of the NOR gate 641 becomes high level. Therefore, the monostable multi 642 operates in response to the rise of the output of the NOR gate 641,
The output is set to low level for a certain period of time T2 (for example, 0.5 seconds). Therefore, Nand Gate 6
43 keeps the output of the monostable multi 642 at high level even while the output Q is at low level. Then, at time t3 after a certain period of time T2 has elapsed from time t2, the output of the monostable multi 642 becomes high level. At this time, the output of the NAND gate 641 is also at a high level, so the output of the NAND gate 643 continues to be at a low level thereafter. Therefore, the solenoid 42 operates for a certain period of time T3 from time t1 to t3.
(for example, for 5 seconds), and during that period, the pair of arm members 36a, 36b continues to be rotated outward. In this way, the pair of arm members 36
a, 36b are rotated outward for a certain period of time T3 based on the winning balls in the winning hole 32, and are moved to the winning area 3.
An area or space leading to 3 is opened, and the ball passing through the space is received and guided to a winning area 33.

By the way, the NOR gate 631 included in the display drive circuit 63 derives the output pulse of the oscillator 630 and supplies it to the driver 632 while the output of the NOR gate 641 is at a low level. In response, the driver 632 causes the lamp 354 to blink in synchronization with the cycle of the output pulse of the oscillator 630, and
It is notified that the pair of arm members 36a and 36b are open.

Next, a case where a ball enters the winning hole 34a will be explained. The ball won into the winning hole 34a is passed through the ball passage 515.
is guided to the path 214 via the ball detection switch 2.
Detected by 3. Depending on the output (low level) of the ball detection switch 23, the NAND gate 612
b derives the high level and monostable multi 613b
give to Accordingly, the monostable multi 613b outputs a high level as the output Q for a certain period of time T4 from time t1. This high level is applied to the NOR gate 621 included in the priority determination circuit 62, the NOR gate 641 included in the solenoid drive circuit 64, and the NOR gate 651 included in the solenoid drive circuit 65.

By the way, when the output of any one of the ball detection switches is received while at least one pair of arm members 36a and 36b are open, the priority order determining circuit 62 drives the balls preferentially in the order of states with the highest winning probability. . That is, the priority determination circuit 62
Noah gates 621 to 623 and inverter 62
Contains 4,625. And the priority determination circuit 6
2 prioritizes the conditions for opening a pair of arm members and the left and right ball receivers, then sets the conditions for opening a pair of arm members and one ball receiver, and finally opens only one pair of arm members. It is set as a condition. Therefore, in this case, in response to the existence of the output Q of the monostable multi 613b, the NOR gate 621 sets its output to a low level, and this low level is inverted to high level, thereby disabling the monostable multi 613a. given as. Therefore, even when the pair of arm members 36a and 36b are being rotated outward in response to the output of the ball detection switch 22, the ball detection switch 23
The action based on the output of is given priority. However, since the output Q of the monostable multi 613b is given to the Noah gate 641, the pair of arm members 36a,
The open state of 36b is continued, and in addition, ball receiving piece 37a is opened. As a result, the pair of arm members 36a and 36b are connected to the monostable multi-layer 613b.
The outward opening state starts from the output start time t1.

More specifically, the solenoid drive circuit 64 is activated in the same manner as when the output of the ball detection switch 22 is activated. Now, monostable multi 613b
During a certain period of time T4 (for example, 6.5 seconds) from time t1 when the output Q of
The output of the Noah gate 633 is set to low level.
and 653. At the falling edge of the NOR gate 651, the monostable multi 652 operates and derives a high level from the output Q for a certain period of time T2 (0.5 seconds). For this reason, Noah Gate 653
sets its output to low level during the time period from time t1', after a certain time T2 has elapsed from time t1, until the output of NOR gate 651 becomes high level (T4-T2=T5). Therefore, driver 654
During the high level period of the output of the NOR gate 653, the output of the solenoid 52a is set to the ground potential.
energize. After that, the monostable multi 613b outputs Q at time t2 after a certain period of time T4 has elapsed.
is set to low level. Accordingly, Noah Gate 651
The output of NOR gate 653 becomes high level, and therefore the output of NOR gate 653 becomes low level. Therefore, the driver 654 sets its output to a high level and deenergizes the solenoid 52b. Accordingly, the ball receiving piece 37a is closed.

Also, at time t2, the output of the NOR gate 641 becomes high level, so the monostable multi 642
is activated. The monostable multi 642 keeps its output at a low level for a certain period of time T2 from time t2.
Therefore, the NAND gate 643 operates for a certain period of time T6 (=2・T2+T5=T4+
T2) makes its output high level. Therefore, the driver 644 derives the high level for a certain period of time T6 from time t1 to t3, and energizes the solenoid 42 during that period. In this case, the lamp 354 and the light emitting diode 39a are displayed blinking.

In this way, the period in which the pair of arm members 36a and 36b are open is selected to be longer by a certain period of time T2 before and after the opening period of the ball receiving piece 37a.
Due to the following reasons. That is, the ball receiving pieces 37a, 37b of this embodiment are a pair of arm members 36a, 36b.
If the arm members 36 are not rotated outward, the pair of arm members 36 cannot be opened even if the solenoids 52a and 52b are energized.
This is to ensure smooth opening and closing operations by lengthening the rotation period of a and 36b by a time corresponding to the driving time for opening or closing the ball receiving piece.

In addition, when the ball detects the output of the ball detection switch 24 due to the ball entering the winning hole 34b,
The operation is performed in the same manner as when the ball detecting switch 23 is turned on, except that the ball receiving piece 37b is opened. That is, the holding circuit 61c has the same circuit configuration as the holding circuit 61b, and the solenoid drive circuit 66 has the same circuit configuration as the solenoid drive circuit 65, but detailed explanation thereof will be omitted.

In addition, the operation when opening the pair of arm members 36a, 36b and the left and right ball receiving pieces 37a, 37b when a ball enters the winning hole 14 is as follows.
The operation is the same as when the outputs of the ball detection switches 23 and 24 are received at the same time, so the explanation thereof will be omitted.

Note that when sound is generated by the sound source circuit 67, it is performed as follows. That is, the sound source circuit 67 includes an oscillator 670. The oscillator 670 derives a constant period clock pulse, and the frequency divider 671
give to The frequency divider 671 provides its frequency divided output to the frequency divider 672, and also provides the NAND gates 673 to 672.
Give to 675. Nand Gate 673, 674
is when there is an output of NAND gate 679, that is, monostable multi 613a, 613b and 61
All outputs of 3c are disabled high (when each is not in operation). NAND gate 675 is activated when there is an output of monostable multi 613b. The reason why the circuit is configured in this way is to change the output frequency of the frequency-divided pulse between the fully open state and other states, thereby making the tone of the sound (the frequency of the sound source signal) different. During the period in which at least one pair of arm members 36a and 36b is rotating outward, the NAND gate 677
will be selected until the output award. The control circuit shown in FIG. 7 and FIG. 8 allows the variable winning ball device to be operated in different modes depending on which of the plurality of winning ball detecting means the detection output is derived from. A drive control means for changing the state to the first state is configured.

As described above, according to this embodiment, since the arm member and the ball receiving piece operate in two stages, there is an advantage that there are many changes in the state in which it is easy to win a prize into the winning hole 33. In addition, compared to a device in which the ball holder piece is directly rotated instead of the arm member, the storage space for the arm member and ball holder piece in the closed state is smaller, but when the arm member and the ball holder piece are opened, The ball can be received over a large area, greatly increasing the winning probability.By deriving and feeding the ball to the amplifier 678, the speaker 68 generates sound.

As described above, according to this embodiment, since the arm member and the ball receiving piece operate in two stages, there is an advantage that there are many changes in the state in which it is easy to win a prize into the winning hole 33. In addition, compared to a model in which the ball holder piece is directly rotated instead of the arm member, there is less storage space when the arm member and ball holder piece are in the open state.
When the arm member and the ball receiving piece are opened, the ball can be received over a large area, which greatly increases the probability of winning a prize, and has the advantage that the service to the players can be greatly improved.

[Effect of the Invention] In the present invention having the above configuration, the mode of change of the variable winning ball device to the first state differs based on the direction in which the winning balls that entered the specific winning hole are sorted. To provide a pinball game machine in which a player can enjoy a variety of changing modes of a variable winning ball device every time a prize is won, and can maintain player's interest over a long period of time through a variety of games.
