Description

[Detailed Description of the Invention] The present invention relates to a thin ball lending machine in which a large number of pachinko machines are arranged and arranged between so-called island machines.

In general, pachinko ball lending machines include large ball lending machines that are installed in pachinko halls and use electrical means, and thin ball lending machines that are placed between machines and do not use electrical means.

Thin ball lending machines have the advantage of being low in cost because they do not use electrical means, but have the disadvantage that the ball lending mechanism must be activated by the weight of the coin.

In other words, a thin ball lending machine generally uses a coin locking plate that has a pawl that engages with a stepped part of a stepped gear that rotates in conjunction with a star wheel that engages with pachinko balls flowing down a ball path and rotates. A predetermined number of pachinko balls are rented out by rotating the pachinko balls with the impact force of the drop and releasing the engagement.
Since the weight of the pachinko balls above the star foil acts on the star foil, the engagement is quite strong. For this reason, ball lending machines generally have a shape that allows the engaging step part and pawl to be easily disengaged, so that this engagement can be reliably disengaged even with the impact force of a falling coin. Therefore, it is necessary to prevent malfunctions caused by causes such as vibration.

On the other hand, in this type of ball lending machine, when two or more coins are continuously inserted, the coins are separated one by one and fed to the locking plate,
It is necessary to ensure that pachinko balls equal to the number of coins inserted are lent out.

The purpose of the present invention is to prevent the locking plate from malfunctioning, and at the same time, utilize the swinging of the locking plate to ensure that coins are fed one by one to the locking plate.

In order to achieve this purpose, the proposed ball lending machine has a stepped gear that rotates in conjunction with a star wheel that engages with pachinko balls flowing down a ball path and rotates, and a stepped gear that engages and disengages from the stepped portion of the stepped gear. In a ball lending machine, the ball lending machine has a locking claw and a coin receiver protruding into a coin passage, and a locking plate that releases the engagement when the coin receiver swings to receive a coin inserted into the coin receiver. A pin is provided protrudingly on the locking plate, and at least one of the upper and lower protrusions protrudes into the coin passage above a portion of the coin passage where the coin receiving portion of the locking plate protrudes, and the coin is inserted into the coin passage. When a coin touches the lower protrusion, it swings and the upper protrusion protrudes into the coin passage, and the coin cutter lever locks the next coin, and the coin cutter lever swings in conjunction with the swinging of this coin cutter lever. and a lateral periphery that comes into contact with a pin of the locking plate to restrict the swinging of the plate when not swinging and releases this restriction after swinging, and a lateral periphery of the locking plate that swings after swinging. A cam is provided having a longitudinal periphery that abuts the pin.

Since the present ball lending machine has the above-described configuration, it has the following effects.

(i) Before a coin is inserted, the coin release lever does not swing and therefore the cam also does not swing, so the pin of the locking plate comes into contact with the lateral periphery of this cam, causing the locking plate to close. Swing is restricted to prevent malfunctions.

(ii) When a coin is inserted, this coin causes the coin cutter lever to swing, and the restriction on the pin of the locking plate by the lateral peripheral edge of the cam is released, so the locking plate swings. The engagement with the stepped gear is disengaged, and thus the predetermined pachinko ball is lent.

At this time, due to the swinging of the coin cutter lever,
If there is a next coin, it will be locked by the upper protrusion of the coin release lever, but due to the swinging of the locking lever, the vertical edge of the cam will come into contact with the pin, causing the cam to Since the swinging of the coin cutter lever is restricted, the swinging of the coin cutter lever is also restricted, so the coin will not hold until the locking plate returns to its original position and the vertical periphery of the cam is no longer in contact with the pin. The locking of the coin by the upper protrusion of the cut lever is not released. Therefore,
Even if coins are continuously inserted, the coins can be reliably fed one by one to the locking plate.

The illustrated embodiment will be described below.

FIG. 1 is a front view of the ball lending machine with the cover removed.

1 is a machine frame, on both sides of which a ball passage 2 and a coin passage 3 are formed.

4 is a star foil whose outer periphery faces the ball path 2, which engages with pachinko balls flowing down the ball path 2 and rotates.

A gear 5 is formed on the star wheel 4, and this gear 5 meshes with a stepped gear 7 via an intermediate gear 6. It's supposed to rotate.

A step body 8 is integrally provided on the front surface of the stepped gear 7, and a protrusion 9 is integrally provided on the back surface. Therefore, the step body 8 and the protrusion 9 are the gear 7
rotate with.

The step body 8 includes first, second, and third step portions 10, 1
1 and 12, a small diameter portion 13 between the first and second step portions 10 and 11, and a small diameter portion 13 between the second and third step portions 1
Between 1 and 12, the middle diameter portion 14 is located, and the third
and the large diameter portion 15 between the first step portions 12 and 10.
A corner portion 16 is further formed in this large diameter portion 15 .

17 is a locking plate, and this locking plate 17 is formed with a curved recess 18 surrounding the step body 8. Two opposing protrusions 19 and 20 protruding toward the step body 8 are formed in the curved recess 18, and the protrusions 19 serve as locking claws.

Further, this locking plate 17 is formed with a coin receiving portion 21 that projects into the coin passage 3, and further has a pin 26 formed on its back surface.

The locking plate 17 can swing about the pivot 22, but its swing is restricted by the projections 19, 20 coming into contact with the step body 8.

Therefore, the rocking of the coin receiving portion 21 protruding into the coin passage 3 is also restricted.

A recess 3b is formed in the wall surface 3a of the coin passage 3 corresponding to the coin receiving portion 21, and the recess 3b serves as a detour for coins.

Reference numeral 23 denotes a coin cutter lever, which is swingably mounted on a pivot 24.

The coin cutter lever 23 has upper and lower protrusions 25 and 27, at least one of which protrudes into the coin passage, above the point in the coin passage 3 where the coin receiving part 21 of the locking plate 17 protrudes.
Further, a pin 23a is provided protruding from the end extending laterally.

Reference numeral 60 denotes a cam that is pivotally supported by a shaft 61 and has a slit 62 formed therein that engages with the pin 23a of the coin cutter lever, and is interlocked with the coin cutter lever 23 by this engagement.

The cam 60 includes a lateral peripheral edge 63 that contacts the pin 26 of the locking plate 17 to restrict the swinging of the plate when not swinging, and a lateral peripheral edge 63 that restricts the swinging of the locking plate 17 after swinging. It has a longitudinal periphery 64 that abuts the pin 26.

This rental machine is further equipped with a fraud prevention mechanism.

Reference numeral 29 denotes a tamper-evident plate, which is approximately L-shaped as a whole, consisting of a horizontal portion 30 and a vertical portion 31, and is connected to the pivot shaft 24.
It is mounted so that it can swing. The tip 32 of the horizontal portion 30 is located in the rotation orbit of the protrusion 9 on the back surface of the stepped gear 7, and the vertical portion 31 has a recess 33 that engages with and disengages from the pin 26 of the locking plate 17. is formed, and a hook portion 34 is further formed below this recessed portion 33.

Reference numeral 40 denotes a coin detection plate, and this detection plate 40 is mounted on a pivot 41 so as to be swingable.

The detection plate 40 has a tip portion 42 that can protrude below the point in the coin passage 3 where the coin receiving portion 21 of the locking plate 17 protrudes.
and the tamper-proofing plate 29.
Two protrusions 43 and 44 are provided at locations facing the hook 34, which can come into contact with and disengage from the hook 34.

Note that the plates 17, 29, and 40 are urged clockwise by the action of the weights 50, 51, and 52 attached to them, and the coin cutter lever 23 is pushed toward the lower protrusion by its own weight and the weight of the cam 60. 23
is energized in the direction of protruding into the coin passage.

In addition, 53 is a regulating member for ensuring the engagement between the star foil and the pachinko balls, 54 is a tank for temporarily storing the released pachinko balls, and 55 is a detection plate 40 that swings once. This limit switch 55 has a sensing needle (not shown) that comes into contact with a suitable position on the sensing plate 40. However, this limit switch may not be installed.

Next, the effect will be explained.

(i) Before a coin is inserted, the pawl 19 of the locking plate 17 is in contact with the small diameter portion 13 of the step body 8 and is engaged with the first step 10, so that the stepped gear 7 is Since the star foil 4 does not rotate, the pachinko balls do not flow down. In this state, only the lower protrusion 27 of the coin cutter lever 23 protrudes into the coin passage 3, and the pin 26 comes into contact with the horizontal edge 63 of the cam 60, thereby restricting the swinging of the locking plate 17 and preventing malfunction. I never wake up. Further, the fraud prevention plate 29 has a vertical portion 31 that is connected to the coin passage 3.
The tip 32 of the horizontal portion 30 enters the back side of the stepped gear 7.
The upper edge of the protrusion 43 of the detection plate 40 comes into contact with the lower edge of the hook 34 of the anti-tampering plate 29, making it impossible to rotate clockwise, and the tip 42 protrudes into the coin passage 3. Not yet.

(ii) When coin a is inserted, coin a passes through the upper protrusion 25 of the coin cutter lever 23 and hits the lower protrusion 27, causing the coin cutter lever 23 to move counterclockwise as shown in FIG. By swinging the cam 60 in response to the swing, the pin 2
The restriction of the horizontal periphery 63 relative to 6 is lifted. As a result, the locking plate 17 becomes swingable, and the coin a hits the coin receiving portion 21 and pushes it down.

Further, at the time when the coin cutter lever 23 swings counterclockwise, the upper protrusion 25 protrudes into the coin passage 3, and if coins are continuously inserted, the next coin a' is It comes into contact with the upper protrusion 25 to prevent it from falling.
At this time, the coin cutter lever 27 and the cam 60 are
As explained earlier, due to its own weight, the upper protrusion 25 of the coin cutter lever 27 is biased in the direction of retreating from the coin passage 3, but the vertical edge 64 of the cam 60 pushes against the pivoted locking lever 17. Pin 2 of
6, its rotation is restricted, so that the coin cutter lever 32 also does not swing, and the next coin a' is securely locked.

The cam 60 has a horizontal peripheral edge 63 shaped like an arc centered on the shaft 61, and a vertical peripheral edge 64 shaped like an arc centered around the shaft 22 of the locking plate, so that the above operation is performed smoothly.

(iii) Coin a is placed in the coin receiving part 2 of the locking plate 17
1 by pressing down on the locking plate 17.
The coin a swings in the counterclockwise direction, and the swinging is regulated by the protruding part 20 of the curved recess coming into contact with the middle diameter part 14 of the step body 8. Therefore, the coin a is 21 and the corner 3d of the coin passage 3 and stop.
figure). In addition, by swinging the locking plate 17 in the counterclockwise direction, the locking pawl 19 and the first step portion 10
Since the stepped gear 7 can be rotated, the pachinko balls engage with the star wheel 4 and flow down while rotating the star wheel 4.

(iv) As the pachinko balls flow down and the star wheel 4 rotates, the stepped gear 7 also rotates clockwise, and when the protrusion 9 on the back side reaches the tip 32 of the horizontal part of the anti-tampering plate 29, It comes into contact with this and pushes up the horizontal part 30.

(v) When the horizontal portion 30 is pushed up as shown in FIG. When the contact is released, the hook portion 34 pushes the other protruding portion 44 of the detection plate (see FIG. 2), so the detection plate 40 swings clockwise, and the tip portion 42 of the detection plate 40 swings clockwise.
protrudes into the coin passage 3, and the recess 33 of the anti-tampering plate 29 surrounds the pin 26 of the locking plate 17.

(vi) As shown in FIG. 4, the stepped gear 7 further rotates,
When the protrusion 9 on the back surface disengages from the tip 32 of the horizontal portion 30 of the tamper-evident plate 29, the tamper-evident plate 29 swings clockwise and attempts to return to its original position; The hook portion 34 of the plate 29 engages with the protrusion 43 of the detection plate 40, and the swinging of the anti-tamper plate 29 is restricted.

(vii) As shown in FIG. 5, the stepped gear 7 further rotates,
When the protruding portion 20 of the locking plate 17 falls from the medium diameter portion 14 of the step body 8 to the small diameter portion 13, the locking plate 17 swings counterclockwise by that amount.
Due to this, until now the coin receiving part 21 and the corner part 3d
The coin a, which was supported by the coin a, falls through the detour 3b, presses down the tip 42 of the detection plate 40, and is then discharged from the machine through the discharge port 3e (FIG. 1).

When the coin a pushes down the tip 42 of the detection plate 40, the detection plate 40 swings counterclockwise, thereby causing the protrusion 43 of the detection plate to engage with the hook 34 of the fraud prevention plate. Since it is released, the tamper prevention plate 29 rotates clockwise and returns to its original position. As a result, the concave portion 33 of the tamper-proof plate is unenclosed from the pin 26 of the locking plate 17, and the locking plate 17 is placed in a state in which it can swing clockwise. Further, the detection plate 40 has a protruding portion 4
3 comes into contact with the hook portion 34 of the anti-tampering plate 29, and the state is the same as the original position.

(viii) When the stepped gear 7 rotates further and the first step 10 of the step body 8 reaches the protrusion 20 of the locking plate 17, it will be pushed to the right in the figure, and the weight 50 will also act. Therefore, the locking plate 17 swings clockwise, and the locking pawl 19 comes into contact with the large diameter portion 15 of the step body 8.

(ix) The stepped gear 7 further rotates and the locking plate 17
As shown in FIG. 6, when the locking pawl 19 comes into contact with the medium diameter portion 14 of the step body 8 and then falls into the small diameter portion 13, the locking plate 17 further swings clockwise.
This allows the pin 26 and the vertical periphery 64 of the cam 60 to
The cam 60 and the coin cutter lever 23 swing and return to their original positions. Then, if there is the next coin a′, coin cutter lever 2
3, the upper protrusion 25 and the coin
The contact between a′ is released, coin a′ falls, and the action explained above is repeated.

As explained in (i) to (ix) above, when a coin is inserted into a main ball lending machine, the stepped gear 7 rotates once, and a corresponding number of pachinko balls are automatically lent out. Even when coins are continuously inserted, each coin is reliably supplied to the locking plate 17 one by one, and the pachinko balls equivalent to the number of coins inserted are lent out. When a coin is not inserted, the locking plate 17 swings and the cam 60
Since it is regulated by, malfunctions will not occur.

In addition, to explain the effect in the case of a fraudulent act, as a fraudulent act, a wire or the like is used without inserting a coin, the coin cutter lever 23 is swung counterclockwise, and the coin is removed from the locking plate 17. When the receiving part 21 is pushed down, (i) the stepped gear 7 rotates as in the case where there is no fraudulent activity, and a certain amount of pachinko balls flow out.

(ii) However, as the stepped gear 7 rotates, the tamper prevention plate 29 swings counterclockwise, and the hook 34 of the tamper prevention plate 29 engages with the protrusion 43 of the detection plate 40 as shown in FIG. Then, since the coin has not actually been inserted, this engagement is not released, and the concave portion 33 of the tamper-evident plate is not surrounded by the pin 26 of the locking plate, so that the large diameter portion of the step body 8 Even if the corner 16 at 15 reaches the protrusion 20 of the locking plate 17 and comes into contact with the protrusion 20 as shown in FIG. 7 to cause the locking plate 17 to swing clockwise,
Since the pin 26 of the locking plate 17 engages with the recess 33 of the tamper-proofing plate 29, the locking plate 17 does not swing, and therefore the rotation of the stepped gear 7 is stopped by the protrusion 20. As a result, the rotation of the star wheel 4 is also stopped, and the falling of the pachinko balls is stopped.

(iii) Furthermore, even if you operate the coin cutter lever 23 and the locking plate 17 as before with a wire or the like, and then try to operate the detection plate 40,
The operation of this detection plate 40 is performed by
4 and the hook part 34 of the tamper-proofing plate 29 are finished, and the corner part 16 of the stepped part body 8 reaches the protrusion part 20 of the locking plate 17, and the time required for this is extremely long. It's practically impossible considering how short it is.

(iv) Also, once the pin 26 of the locking plate 17 is
When the star foil 4 is engaged with the concave portion 33 of the fraud prevention plate 29, this engagement is quite strong due to the weight of many pachinko balls being applied to the star foil 4. It becomes impossible to remove it. Further, when the locking plate 17 attempts to swing clockwise, the pin 26 causes the tamper-proofing plate 29 to rotate counterclockwise, and the pin 26 moves into the recess 33.
By engaging with the inner part 33' of the holder, the engagement becomes even more reliable.

Therefore, if the above-mentioned fraudulent act is committed, the ball lending machine will be suspended from use until the pachinko hall staff takes appropriate action.

Next, as a fraudulent act, the detection plate 40
If the user commits the same fraudulent act as before by fixing the coin with wire or any other means so that its tip 42 does not protrude into the coin path 3, (i) the stepped gear will be removed in the same way as if there was no fraudulent act; 7 rotates and some pachinko balls flow out.

(ii) However, when the stepped gear 7 rotates and its protrusion 9 reaches the horizontal end 32 of the anti-tampering plate 29 as shown in FIG. Therefore, counterclockwise rocking of the anti-tamper plate 29 is restricted by the hook portion 34 coming into contact with the protrusion 44 of the detection plate 40 as shown by the imaginary line in FIG.

(iii) Therefore, the rotation of the stepped gear 7 is caused by the projection 9
The star wheel 4 is stopped by contacting the horizontal end 32 of the tamper prevention plate, and the rotation of the star foil 4 is also stopped, thereby stopping the pachinko balls from flowing down.

(iv) Furthermore, even if the detection plate 40 is released after that, the hook part 34 of the fraud prevention plate and the protrusion part 43 of the detection plate 40
, so it will work in the same way as in the case of fraud mentioned earlier.

Furthermore, as a fraudulent act, a string is attached to the coin,
Even if you try to pull the coin back after dropping it halfway, in that case, the lower protrusion 27 of the coin cutter lever 23 or the lower surface of the coin receiving portion 21 of the locking plate will come into contact with the upper surface of the coin. Since it acts as a stopper, it naturally prevents such fraud.
