Description

[Detailed Description of the Invention] This invention relates to a pachinko ball discharging device for a ball lending machine, in which a specified number of pachinko balls are ejected by inserting a coin, and a player can play a game with the pachinko balls using the pachinko balls.

As is well known, ball rental machines with a short width and almost the same height as a pachinko machine are installed between the pachinko machines in a row of pachinko machines.

This ball rental machine has a short width, so it cannot be made into a very complicated structure.

Conventionally, when a coin is inserted, a switch is turned on, which excites the electromagnet, causing the drive wheel to rotate a certain amount (for example, 2.5 times), and the rotation of the drive wheel discharges a specified number of pachinko balls.

Therefore, pachinko balls are ejected immediately when the coin switch is turned on, so it is common practice to insert a metal wire into the coin slot or the pachinko ball ejection port, turn on the switch, and illegally eject pachinko balls. ing.

This project was devised in view of the above, and uses an extremely simple structure to reliably prevent the unauthorized ejection of pachinko balls, and to ensure that the exact specified number of pachinko balls are always ejected by inserting the correct coin. be.

The present invention will be described below with reference to the illustrated embodiment. A pachinko ball discharging device 1 is provided in the upper part of the interior of the pachinko ball rental machine.

This ejection device 1 includes a drive wheel 2 whose one side faces the pachinko ball passage a, a control wheel 4 that meshes with a gear 3 that is integrated with the drive wheel 2, and a solenoid that starts the rotation of the control wheel 4. 5
are the main components.

As is well known, the drive wheel 2 has, for example, ten semicircular notches on its outer periphery, one side facing the passage gutter a, and when it is in a free rotation state, each notch receives one pachinko ball. The balls are then flowed down the passageway a and are discharged to the pachinko ball outlet of the pachinko ball discharging device.

Therefore, when the drive wheel 2 rotates 2.5 times, 25 pachinko balls are ejected to the player.

The control wheel 4 associated with the gear 3 that rotates integrally with the drive wheel 2 is provided with a stopper plate 7 on one side of a large-diameter gear 6 that meshes with the gear 3, and a cam plate 8 on the other side. It is rotatably supported.

The stopper plate 7 has a first stopper part 9 and a plurality of hook-shaped second stopper parts 10 raised on the outer periphery of the disk, and a final second stopper of the first stopper part 9. A downward hook-shaped third stopper part 11 is positioned between the third stopper part 10' and the third stopper part 10'.

The cam plate 8 is provided with a notched cam portion 8' approximately half its length on its outer periphery, and a vertical portion 12 is formed at one end of the cam portion 8', and an arcuate portion 13 is formed at the other end.

Therefore, when the control wheel 4 rotates, the large-diameter gear 6, stopper plate 7, and cam plate 8 are in the same direction and at the same speed.

The stopper plate 7 and the cam plate 8 mentioned above have a lubar 14.
and the second lever 15 are associated.

The first lever 14 and the second lever 15 are each rotatably supported by a shaft 16, but can be rotated individually.

Therefore, the louver 14 and the second lever 15 may be rotatably supported by separate shafts.

The lever 14 has a locking pawl 17 projecting sideways at its tip so as to face the outer peripheral surface of the stopper plate 7, and its rear end engages with the excitation rod 5' of the solenoid 5, and is engaged by a spring, its own weight, etc. The retaining pawl 17 is urged to come into pressure contact with the outer surface of the stopper plate 7.

The second lever 15 has a protruding engagement portion 18 at its tip and a cam plate 8.
The upper end of the connecting member 19 is connected to the rear end thereof.

On the other hand, there is a coin flow path 20 in the lower part of the inside of the ball lending machine that judges the inserted coin with an identification mechanism (not shown) and drops the coin into a safe (not shown) below if the coin is correct. , the coin control mechanism 21 is placed in the middle of the flow path 20.

As is well known, the control mechanism 21 has an inverted shape consisting of a vertical piece 22 and a horizontal piece 23, and its bent part is pivotally connected to a shaft 24 to be rotatably supported. The first pawl 25 and the second pawl 26 are provided laterally, separated by approximately the diameter length of the two pawls, and both pawls 25 and 26 are exposed to the inside of the flow path 20.

Further, inside the flow path 20, a lever 28 of a coin detection switch 27 is located between the first pawl 25 and the second pawl 26.

The solenoid 5 and the switch 27 are electrically connected, and the lower end of the connecting member 19 of the second lever 15 is pivotally connected to the rear end of the horizontal piece 23 of the control mechanism 21.

As a result, the second lever 15 is biased mainly by the weight of the connecting member 19 so that the engaging portion 18 comes into pressure contact with the outer peripheral surface of the cam plate 8 .

When a pachinko player inserts a proper coin into the slot, the coin falls down the flow path 20 from the identification mechanism, and the coin falls through the lever 28.
While turning the switch 27 on, turn the first claw 25.
It can be stopped.

If you insert coins continuously, subsequent coins will be placed in the first claw 2.
The coin stopped at step 5 prevents the coin from falling and leads to the flow path 2.
Stays within 0 sequentially.

When the switch 27 is turned on, the solenoid 5 is energized, so the ejection device 1 is driven and the pachinko balls are ejected. When a certain number of pachinko balls are ejected, the control mechanism 21 rotates so that the first claw 25 moves into the flow path 20. At the same time, the second claw 2
6 rushes into the flow path 20 and supports the second coin from the bottom.

Therefore, the coins on the bottom row fall into the safe, and at the same time the switch 27 is turned off.

When the switch 9 is turned off, the solenoid 5 is demagnetized, and when the ejection device 1 has finished ejecting the specified number of pachinko balls, the control mechanism returns and rotates, and the coins that were held by the second pawl 26 are moved to the first pachinko 25. At the same time, the switch 27 is turned on and the ejection device 1 is activated to start ejecting the pachinko balls again.

Therefore, the control mechanism 21 controls the destination of one coin when coins are continuously inserted, and the switch 27
starts the ejection operation of the pachinko balls.

Since the present invention is constructed as described above, in the normal state where no coin is inserted, the locking pawl 17 locks the first stopper part 9 of the stopper plate 7 under the bias of the second lever 14, and the control wheel 4
rotation is stopped.

For this reason, the driving wheel 2 does not rotate due to the meshing between the large diameter gear 6 and the gear 3, and the pachinko ball in the passageway a is transferred to the driving wheel 2.
is stopped by.

When a proper coin is inserted in this state, the switch 27 is turned on as described above, the solenoid 5 is energized, and the excitation rod 5' is lowered.

When the excitation rod 5' is lowered, the louver 14 rotates against the bias, and the locking pawl 17 is disengaged from the first stopper part 9, so the control wheel 4 becomes in a free rotation state, and the drive wheel 2 also rotates freely. state.

Therefore, due to the downward force of the pachinko ball flowing through the passageway a, the driving wheel 2
The receiver inserts one pachinko ball into each notch and rotates.
Since this rotation is transmitted to the gear 3 and the large diameter gear 6, the control wheel 4 also rotates at a reduced speed.

When the pachinko balls sequentially flow down the passageway a and the drive wheel 2 rotates, and the control wheel 4 rotates approximately half a turn, the retaining part 18 moves to the vertical part 12.
The second lever 15 engages the cam portion 8' from the cam portion 8'.
It rotates by the depth of .

When the second lever 15 rotates, the connecting member 19 descends, and the control mechanism 21 rotates to drop the coin held by the first claw 25 into the safe, and at the same time, the switch 27 is turned off.

When the switch 27 is turned off, the solenoid 5 is demagnetized, so the second lever 14 is energized and rotated back to the excitation rod 5'.
rises.

At the same time, the locking pawl 17 comes into contact with the stopper plate 7, and the locking pawl 17 is brought into contact with the final stopper plate 7 in accordance with the position where the retaining portion 18 engages the cam portion 8' from the vertical portion 12. 2
It enters between the stopper part 10' and the third stopper part 11 and contacts the outer surface of the stopper plate 7.

Therefore, the rotation of the drive wheel 2 causes the control wheel 4 to rotate continuously, and when the locking pawl 17 hits the first stopper part 9, the rotation of the control wheel 4 and the drive wheel 2 is stopped and the passage gutter a Stop the pachinko ball from flowing.

Also, just before the locking pawl 17 hits the first stopper part 9, the retaining part 18 slides up the arcuate part 13 of the cam part 8', and at the same time as the locking pawl 17 hits the first stopper part 9, the retaining part 18 slides up the arcuate part 13 of the cam part 8'. It is located on the outer peripheral surface of the plate 8.

As a result, the second lever 15 is rotated back, the connecting member 19 is raised, and the control mechanism 21 is rotated to wait for the next coin insertion.

However, if multiple coins remain in the flow path 20, the second
The coin held by the pawl 26 falls and is supported by the first pawl 25, and the switch 27 is immediately turned on to repeat the pachinko ball ejecting operation described above.

As described above, according to the present invention, the control wheel 4 has the second lever 14 and the second lever.
The levers 15 are individually engaged, and when a proper coin is inserted, the solenoid is energized and the first lever 14 is detached from the stopper plate 7 and rotated. When the second lever 15 engages with the cam plate, the second lever 14 is moved again to the stopper plate. 7, the stopper plate 7 locks the first stopper part 9 to stop the rotation of the control wheel, and simultaneously removes the second lever 15 from the cam part.

In such a structure, if a player wants to illegally eject a pachinko ball without inserting a coin, he can either insert a metal wire and turn on the switch 27, or he can rotate the lever 14. It is.

When the switch 27 is turned on, the solenoid 5 is energized, the lever 14 is rotated, the control wheel 4 is freed, the drive wheel 2 is rotated, and the pachinko balls are ejected.

However, the point at which the solenoid 5 is demagnetized (the switch 27 is turned off) must be between the locking pawl 17 of the louver 14 and the 'final second stopper part 10' and the third stopper part 11; If so, the locking claw 17 is the second stopper part 1
0, and thereafter it will be stopped by the third stopper part 11.

In particular, since the third stopper part 11 has a downward hook shape,
To fix a locking claw 17 even when turning off a switch 27 is delayed.

Therefore, without looking at the rotational state of the control wheel 4,
The locking claw 17 of the stopper part 10' and the stopper part 11
Since it is extremely difficult to turn off the switch 27 when the switch 27 is located between the two, it is possible to almost prevent unauthorized operation of the switch 27.

On the other hand, even in the case of a fraudulent act in which the first lever 14 is rotated with a metal wire or the like, the locking pawl 17 comes off from the first stopper part 9, and the control wheel 4 becomes free and the drive wheel 2 rotates, causing the fraudulent act. Pachinko balls are ejected.

However, similarly to the above, the locking claw 1 prevents the return rotation of the lever 14.
7 is the final second stopper part 10' and the third stopper part 1
Since it must be between 1 and 1, it is possible to reliably prevent fraud.

Note that the locking claw 17 and the stopper parts 10.10', 11 are provided with metal pieces and connected to an electric circuit, and when the locking claw 17 and the stopper parts 10.10', 11 come into contact, the circuit is closed. An alarm for detecting fraud prevention may be activated.

In summary, according to the present invention, the control wheel is provided with a stopper plate and a cam plate so that the individually actuated first and second levers can be engaged with each other, so the structure is extremely simple. It is possible to reliably prevent fraud regardless of the situation, and the specified number of pachinko balls are accurately ejected only when the correct coin is inserted.

Moreover, it can be incorporated into conventional ball lending machines and used as is, and has high practical value.
