DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a prize ball device for a pachinko machine, in which a fixed number of prize balls are arranged in the middle of the length of a prize ball gutter which is installed vertically and whose upper end is connected to a supplementary ball gutter for prize balls. A prize ball storage chamber capable of storing balls is provided, an inflow regulating door is provided at the upper inlet of this storage chamber, and an outflow regulating door is provided at the lower outlet of the storage chamber, each of which is swingable about a supporting shaft, Furthermore, these two regulating doors are connected by an interlocking member, and in normal conditions when no safe balls fly in, the locking portion provided on the interlocking member is engaged with the engaging portion provided on the swinging free end of the outflow regulating door. At the same time, the inflow regulating door is kept in the closed state and the inflow regulating door is kept in the open state to store a constant number of prize balls inside the storage chamber, and when a safe ball enters, the interlocking member is activated by the operation of the detector that detects this. When activated, the outflow restriction door is disengaged, the outflow port of the storage chamber is opened, and the prize ball is discharged. At the same time, the inflow restriction door is closed to prevent the inflow from the supplementary ball gutter, thereby releasing the safe ball. To provide a prize ball device for a pachinko machine which can always accurately and quickly release a fixed number of prize balls in response to incoming balls.

Hereinafter, the present invention will be explained with reference to the embodiments shown in the drawings. 1 is a base frame that is the base of the device of the present invention;
2 is a prize ball gutter provided vertically along this base frame body, and 3 is a prize ball storage chamber provided in the middle of this prize ball gutter. And 4 is the safe ball passage that guides the safe ball,
5 is a detector for detecting the safe bulb flowing down this safe bulb passage, and 6 is a controller provided on the way to this detector.

The base frame 1 is configured to integrate the prize ball system and the safe ball detection system in a pachinko machine to improve the accuracy of the device, as well as to simplify and facilitate assembly. It is formed into an L-shape, and the prize ball system mechanism is placed in the vertical part, and the safe ball detection system mechanism is placed in the horizontal part.

This base frame body is assembled along the back side on the left side of the game board housed inside the pachinko machine, and the upper end opening of the prize ball gutter 2 provided in the vertical part is used to store prize balls (not shown) outside the machine. A supplementary ball gutter is connected to the safe ball passage 4, and a safe ball collection gutter provided on the back side of the game board (not shown) is connected to the safe ball passage 4, so that the safe balls received through the prize opening of the game board flow into it.

Now, the prize ball gutter 2 has an upper end portion oriented diagonally sideways, and a part that descends vertically from this meandering part, with a prize ball storage chamber 3 provided directly below it.

In this embodiment, the storage chamber 3 is formed into an independent cylindrical body by cutting out a part of the prize ball gutter 2, and the openings at the upper and lower ends thereof are connected to the prize ball gutter and become a part thereof. The upper end of this storage chamber 3 is pivotally connected to the base frame by a support shaft 7, and while the lower end of the cylinder is always connected to the prize ball gutter, as will be described later, the prize ball inside the prize ball gutter is When a ball is to be punched, the spindle 7 is swung as a fulcrum, so that the lower end opening is communicated with a ball punching gutter 8 which is arranged parallel to the prize ball gutter 2.

Reference numeral 9 denotes a spring that urges the lower end opening of this storage chamber 3 to communicate with the prize ball gutter 2. It is hung on a protruding pin 11. A pin 13 is provided at the lower end of the storage chamber 3 and protrudes rearward through a long hole 12 similarly opened in the base frame 1, and a stopper 14 is attached to this pin.
is latched, and the storage chamber 3, which has been returned to communicate with the prize ball gutter 2, can be restrained in that position by the spring 9.

Incidentally, the storage chamber 3 is arranged to take an inclined posture when in a normal state where it communicates with the prize ball gutter 2. When prize balls are stored inside, they are pressed into a vertical position by the weight of the prize balls and face the ball extraction gutter 8 located directly below. Therefore, when the stopper 14 is removed, the storage chamber 3 automatically communicates with the ball extraction gutter 8, and the prize balls flowing inside are discharged into the ball extraction gutter 8. When the ball is removed, it is released from the weight, and the restoring force of the spring 9 acts on it, so it communicates with the prize ball gutter 2 again, and at the same time, the stopper 14 engages with the pin 13, restraining it in its normal position. .

Reference numeral 15 denotes an inflow control door that restricts the inflow of prize balls into the storage chamber 3, and 16 is an outflow control door that holds the balls stored in the storage chamber 3 until a detector 5, which will be described later, detects a safe ball. , 17 is an interlocking member that is connected to the link 18 that transmits the operation of the detector 5 and simultaneously operates the inflow regulating door 15 and the outflow regulating door 16 when the detector is operated.

The interlocking member 17 has a plate shape and has a support shaft 1 attached to the base frame 1.
9, and is pivoted so that it can swing freely, and is designed to swing about a support shaft 19 as the connecting rod 18 moves up and down.

The interlocking member 17 has a locking portion 21 on its lower edge that locks the pin 20 of the outflow regulating door 16, and an elongated hole 23 on its upper edge that slides into the pin 22 of the inflow regulating door 15.

The inflow regulation door 15 and the outflow regulation door 16 are arranged vertically on the side of the storage chamber 3, and the inflow regulation door 1
5 is connected to the support shaft 24, and the outflow control door 16 is connected to the support shaft 2.
5, each of which is pivotally connected to each other so as to be freely swingable. The inflow regulating door 15 has a stopper piece 26 provided at the upper end facing a window 27 opened in the middle of the prize ball gutter 2 corresponding to the upper end opening of the storage chamber 3, and a pin 22 provided at the tip of an arm 28 extending downward. As described above, the interlocking member 17 is slidably fitted into the long hole 23 of the interlocking member 17 to be connected thereto.

On the other hand, the outflow control door 1 is pivotally supported by a support shaft 25.
6 hangs down along the side of the storage chamber 3, and a lid piece 29 provided at the lower end faces the outlet of the storage chamber 3. This lid piece 29 is usually held by a weight 30 fixed to the back. It is biased so as to protrude to the outlet of the storage chamber 3. In addition, this bias is applied to the prize ball 1 in the storage chamber.
It is made to be weaker than its weight.

The regulation door 16 has the pin 20 provided at the lower free end thereof passed through an elongated hole 31 provided in the base frame so as to face and engage with the locking portion 21 of the interlocking member 17.

By the way, the detector 5 is pivoted freely around a support shaft 32 so that the tip of the arm faces the safe ball passage 4.

This detector 5 always flips up the tip by receiving the weight of the connecting rod 18 connected to the rear end, and waits for the safe ball flowing into the safe ball passage.When the safe ball flows in, the support shaft 32 The interlocking member 17 is actuated by swinging around the fulcrum and pushing up a linking rod 18 connected to the rear end. In this embodiment, the detector for detecting the safe ball is configured mechanically, and the weight of the safe ball is used to detect the support shaft 32.
The passage of the safe ball is detected by this swinging motion, and the interlocking member is actuated via the connecting rod 18. Needless to say, it may be electrically configured, for example, by exciting a solenoid or operating a motor to directly operate an interlocking member based on the detection signal.

Figures 1 and 2 show the state in a normal state without the safety ball, and as the detector 5 flips up and the linking rod 18 descends, the linking member 17 is moved to its free end side (left side in the drawing). ) is kept in a lowered state. At this time, the interlocking member 17 is
Since the lower edge of the door lowers and the locking part 21 engages with the pin 20 of the inflow regulation door 16, this regulation door is closed to the storage chamber 3.
While blocking the exit of the storage chamber, the inflow regulating door 15 with the pin 22 slidably fitted into the elongated hole 23 retreats the stopper piece 26 from the window 27 and prevents the release of prize balls inside the storage chamber. Prize balls flowing down through the ball gutter can be freely received into the storage chamber 3.

In addition, in this embodiment, the storage chamber 3 includes the area outside the cylindrical portion that swings around the support shaft 7 and up to the middle of the prize ball gutter 2 into which the stopper piece 26 of the inflow regulating door 15 enters. It is designed to accept and store a fixed number of prize balls.

Next, in this state, when the safe ball flows into the safe ball passage 11 and the detector 5 is pushed down by the weight of the ball, the interlocking member 17 swings as the linking rod 18 rises, so the locking portion At the same time as the pin 20 engaged with the pin 21 comes off, the pin 22, which is slidably fitted into the elongated hole 23, is pushed out to the left while being guided by the elongated hole.

FIG. 3 shows this state. As the pin 20 disengages, the outflow control door 16, which was receiving the prize balls inside the storage chamber 3, is pushed out to the right by the cover piece 29. The ball swings around the support shaft 25, and the prize ball is released into the prize ball gutter 2 below. At the same time, the inflow regulating door 15 swings about the support shaft 14 and pushes the stopper piece 26 into the window 27 to block the middle of the prize ball gutter, thereby stopping the prize balls flowing into the storage chamber 3.

Since the opening of the outflow regulation door 16 and the inflow regulation of the inflow regulation door 15 are performed simultaneously with the operation of the interlocking member 17, the prize balls that continuously flow into the storage chamber 3 through the prize ball gutter are blocked by the outflow regulation door 16. Only a constant number of prize balls are released from the lid piece 29 to the stopper piece 26 of the inlet regulating door 15, and the prize balls that are sent in continuously are waited at the position of the stopper piece 26. When there are no prize balls in the storage chamber due to the release of the prize balls, the outflow restriction door 16 automatically returns to the closed state, returns the pin 20 to the position facing the locking part 21 of the interlocking member 17, and detects the ball. The container 5 also returns to its original state and lowers the linking rod 18 to move the linking member 1
7, the pin 20 is attached to the locking portion 21.
is engaged, and the outflow restriction door 16 is again restrained in the closed state. Since the inflow regulating door 15 is opened at the same time as this closing, the storage chamber 3 is again filled with a fixed number of prize balls and is prepared for the next safe ball to enter.

In the figure, 33 is a stop device that restricts the operation of the interlocking member 17 and stops the release of prize balls when the prize balls supplied to the prize ball gutter 2 are missing.

The stop device 33 engages with a detection plate 34 provided on the upper wall surface of the horizontally inclined prize ball gutter 2 when this detection plate is activated, and presses down the interlocking rod 35 connected to the interlocking member. Swinging rod 3 that restrains
It consists of 6.

The detection plate 34 is formed into an L-shape by a detection plate part 37 parallel to the upper surface of the prize ball gutter 2 and an engagement plate part 38 extending at a substantially right angle from the rear end. The end is pivotally supported by a support shaft 39 so that it can swing freely.

This detection plate 34 is configured so that when the prize ball gutter 2 is filled with prize balls, the detection plate portion 37 is pushed up by the balls and the engagement plate portion 38 is held in an approximately vertically erected state. be. On the other hand, the swinging rod 36 is swingably supported by a support shaft 40, and one free end of the swinging rod 36 faces the engagement plate part 38, and an engagement pin 41 provided thereon is attached to the engagement plate part 38 so as to raise the engagement plate part. An interlocking rod 35 whose one end is connected to the interlocking member 17 is pivotally connected to the other free end.

In the normal state when the prize ball gutter 2 is full of balls, this stopping device pushes up the plate portion 37 of the detection plate with the diameter of the ball.
The engagement plate portion 38 is vertically erected to allow free swinging of the swinging rod 36 and vertical movement of the interlocking rod 35 connected thereto, thereby freeing the operation of the interlocking member 17. When the prize ball inside is chipped, the detection plate part 37 falls into the gutter due to its own weight, and the engagement plate part 38 tilts and protrudes toward the engagement pin 41 side of the swinging rod 36, and its upper edge is placed under the engagement pin 41. In order to hide in
The swinging of the swinging rod 36 is stopped.

Therefore, according to this embodiment, when there are no prize balls left in the prize ball gutter 2, the interlocking member 17 is restrained via the interlocking rod 35 as the swinging rod 36 stops swinging, so that the flight of the safe ball is prevented. Even if the detector 5 detects this due to the entry, it will not operate, and the release of prize balls from the storage chamber 3 will be automatically stopped.

As described above, the device of the present invention is configured such that when a safe ball flies in and passes through the safe ball passage 4, the detector 5 is swung by the safe ball to raise the linking rod 18, and the linking rod 18 is raised. In order to operate the member 17 and release the pin 20 that is locked to the locking part 21, the outflow control door 16 that had received the prize ball until then opens,
The prize balls in the storage chamber 3 are discharged into the prize ball gutter 2.

The released prize balls fall while hitting a bell 42 provided in the middle of the prize ball gutter, and are discharged through a window 43 into a prize ball tray provided at the front of the Pachinko machine (not shown).

On the other hand, at the same time as the outflow regulation door 16 is opened, the inflow regulation door 15, which had been kept open until then, swings and thrusts its stopper piece 26 into the prize ball gutter to prevent the inflow of prize balls. In this case, only the number of balls in the storage chamber 3 will be released, and a fixed number of prize balls will always be released.

In this way, the device of the present invention provides for one safe ball,
Although it is guaranteed that a certain number of prize balls will always be released, when the outflow control door 16 that stops the release of prize balls in the storage chamber 3 is in a closed state, the pin 20 is inserted into the locking part 2 of the interlocking member.
This state is maintained by engaging the pin 1, and at this time, the prize ball is received in the storage chamber and urged in the release direction, so the prize ball is instantly released at the same time as the pin is engaged. This will result in the release of As soon as this ejection is completed, the biasing effect of the prize ball is released, and the ball automatically returns to the closed position. Therefore, extremely quick and accurate operation can be expected.

In addition, the prize ball storage chamber 3 of the device of the present invention is always in a fixed state, and the stored prize balls can be released only by swinging the outflow control door 16. When removing the ball, the stopper 14 is removed from the pin 13, and the lower end opening of the storage chamber 3 is automatically inserted into the ball removal gutter 8 by retreating from the outflow regulating door 16 which is kept in the closed state. Since the balls can be communicated with each other, the ball removal work can be easily performed.

Of course, during this work, the inflow regulating door 15 connected to the interlocking member 17 is kept open, so
At the same time as all the prize balls sent through the supplementary ball gutter are released, these prize balls are also released through the storage chamber 3, so that no prize balls remain in the storage chamber and balls can be completely removed from the pachinko machine. Can be done. In addition, at the same time as the ball is removed, the storage chamber 3 is released from the weight of the prize ball and returns to its original state, and the stopper 14 engages the pin 13 again, so that the next time the prize ball is replaced, the prize ball is no longer available. Because it is set to a possible state,
It is extremely convenient to handle.

In addition, in the device of the present invention, when there is a shortage of supplementary balls, the stop device 33 operates to stop and restrain the operation of the interlocking member 17, so that the device releases the missing prize balls or operates idly. This means that a constant number of prize balls are always released.
