Description

[Detailed description of the invention] The present invention relates to an automatic pachinko ball lending machine in the form of a vending machine that rents out pachinko balls, and in particular, the automatic ball lending machine for pachinko is designed to reliably prevent pachinko balls from being stolen by external operations. Regarding a device for preventing unauthorized operation in rental machines.

Recently, pachinko balls, which are lent out in predetermined quantities at pachinko parlors, are being lent out using pachinko ball rental machines in the form of vending machines, as pachinko parlors are saving labor.

With the trend toward central control of the supply and collection of pachinko balls, pachinko ball rental machines have also been incorporated into a series of pachinko ball supply systems, and are installed between pachinko machines when they are installed, saving space and making them easily accessible. Pachinko balls can be rented at some locations.

However, in a ball lending machine that uses the falling motion of the coin itself to issue a command to throw out pachinko balls when a coin is inserted, for example, a string is tied to the coin and the coin is inserted from There is a risk test in which a fraudulent operation is carried out in which pachinko balls are thrown out without limit by repeatedly activating the coin sensing member.

In view of this, the present invention aims to provide an unauthorized operation prevention device for an automatic pachinko ball lending machine that can reliably prevent pachinko balls from being stolen due to unauthorized external operations as described above. It has been done.

The present invention will be explained below with reference to embodiments shown in the drawings.

An example of the structure of the dispensing device 1 to which the tampering prevention device according to the present invention is applied will be described. As shown in FIG. This machine frame 3 has a star foil-shaped ball counter play 1 which partially protrudes into the ball passage 4.
is rotatably mounted on a shaft 6, and is arranged so that each pachinko ball passing down the passage 4 is fed one tooth at a time.

In the illustrated embodiment, the concave portion between each tooth of the ball counter plate 5 is formed in a curved concave shape corresponding to the radius of a pachinko ball, and the number of teeth is 10, and IO pachinko balls pass through it to make one rotation. It is configured as follows.

The ball counter plate 5 is provided with a gear 7 that rotates together with the ball counter plate 5, and a shaft 8 provided in parallel with the axis 6 of the ball counter plates 1 to 5 has a gear 9 and a gear 9 that rotates out of phase with the ball counter plate 5. The two cams 10a and 10b and the ball counter stop plate 11 are attached so as to rotate together.

The gears 7 and 9 are interlocked by an intermediate gear 12, and the tooth ratio of the gears 7 and 9 is such that the number of teeth of the ball counter plate 5 corresponds to one predetermined coin C while the gear 9 rotates once. It is set so that it is rotated by the number of pachinko balls to be played.

The ball counter stop plate 11 has a stepped portion 13 formed on a part of its outer periphery, and a large-diameter portion 14 extending over a required range from the stepped portion 13 toward the rear in the rotational direction. It has a habit of rotating clockwise in the figure within the allowable range of movement.

A stop pawl 18 of a stop release lever 17 is disposed on the stepped portion 13 so as to be able to be engaged therewith.

This stop release lever 17 is rotatably supported on the machine frame 3 by a shaft 19, and a coin abutting portion 20 at one end thereof is provided so as to protrude vertically movably into a coin passage 21.
A coin C falling inside the container 1 collides with the upper surface of the coin C.

In addition, a weight 22 is attached to the other end of the stop release lever 17.
is provided, so that when the coin C collides with the coin abutting portion 20, the stop claw 18 is easily removed from the stepped portion 13.

The stop release lever 17 must be made of a lightweight material such as synthetic resin or light metal so that it can respond more sensitively to a collision when the coin C falls due to its own weight.

The coin stopper 23 is attached to the shaft 2 on the machine frame 3 at a position spaced apart above the coin abutting portion 20 of the stop release lever 17.
4, and the surface of the pivoted upper end portion on the coin passage 21 side is formed into a coin fitting part 25 recessed in an arc shape into which a part of the coin C can be engaged, and the lower part is extended downward. and hangs down by its own weight along the outer surface of the wall of the coin passage 21,
When hanging down, the upper end 25a of the coin fitting portion 25 is placed on the same inner surface as the inner wall surface 21a of the coin passage 21, and the lower end 25b inevitably enters the coin passage 21 to prevent the coin C from falling. It is designed to prevent

And the coin passage 2 of the extension part of the coin stopper 23
A substantially U-shaped recess 26 is formed in the portion facing the stop release lever 17, and a pin 28 at the tip of an arm 27 protruding from the stop release lever 17 is fitted into this recess 26. , the pin 28 is disposed so that it comes out of the recess 26 only when the coin stopper 23 moves counterclockwise to allow the coin C to pass.

A coin stopper lock lever 30 for locking the coin stopper 23 is pivotally supported on the machine frame 3 by a shaft 31, and its locking portion 32 is disposed so as to be freely engageable with a stepped portion 33 of the coin stopper 23 under the bias of a spring 34. It is set up.

The return lever 35, which ensures the return of the stop release lever 17, is pivotally supported on the machine frame 3 by a shaft 36, and one end of which is supported by a spring 37 so that the protrusion of the cam 10a is slightly in front of the cam 10a.
An arm 3 is pressed against the cam surface of the arm 3 and extends to the other end of the arm 3.
8 is disposed such that it can be freely engaged with the arm 39 extending above the stop release lever 17, and the return lever 35 or the cam 1
When the arm 38 is pushed up by the stop release lever 17, the arm 38 comes into contact with the arm 39 of the stop release lever 17, and this release lever 1
7 does not return at a predetermined timing due to clogging with garbage or other reasons, it is forcibly returned.

Further, the opposite end 40 is made into an abutment mark on the back surface of the coin stopper 23, so that when pushed up by the cam 10a as described above, the coin stopper 23 is held in the coin stop position (state B in FIG. 3). It has become.

An auxiliary lever 41 is pivotally supported coaxially with the return lever 35. One end of this auxiliary lever 41 is pressed against the rearwardly displaced cam 10b under the force of a spring 42, and the other end 43 is pressed against the cam 10b that is displaced rearward. It can freely come into contact with the back of the lock lever 30,
When pushed up by the cam 10b, the lock lever
30 and the stepped portion 33 of the coin stopper 23.

The stop release lever restraining member 50 has its upper end aligned with the shaft 5 so that one side enters the coin passage 21 as shown in FIG.
The restraining member 50 has a U-shaped side surface that enters the coin passage 21, into which the coin abutting portion 20 of the stop release lever 17 can loosely fit. A recess 52 is formed.

The side edges extending upward from the upper ends of these four parts 52 are inclined edges 5.
3, and is formed so that when it hangs down due to its own weight around the shaft 51, this inclined edge 53 crosses the thickness direction of the coin passage 21.

The upper edge 52A forming the four parts 52 is more protruded than the lower edge 52B, and at the moment the coin C pushes away the upper edge 52A and passes through it, the upper edge 52A It is designed to protrude into the passage 21.

Further, the lower end of the restraining member 50 is designed so that it does not come off the side edge even when the coin contact portion 20 of the stop release lever 17 is lowered to its lowest position, so that it does not become a hindrance when the stop release lever 17 returns to the upward position. It has become.

In FIG. 1, 54 is a cabana for reliably feeding the ball counter plate 5 one tooth at a time, 55 is a fraudulent coin outlet, and 56 is a superior outlet.

Next, the operation of the above embodiment will be explained.

When pachinko balls are being supplied to the automatic pachinko ball rental machine, the pachinko balls fill the ball passage 4 and reach the ball counter plate 5.

At this time, as shown in the first diagram, the stop pawl 18 of the stop release lever 17 of the roll dispensing device 1 is engaged with the stepped portion 13 of the ball counter stop plate 11, so that the gear 9 integral therewith is stopped. Therefore, since the gear 7 that meshes with the intermediate gear 12 is also stopped, even if the load of the pachinko balls is applied to the teeth of the ball counter plate 5, which is integrated with the gear 7, it does not rotate and remains stationary. ing.

In this state, when coin C is inserted from the coin slot, it passes through a coin passage (not shown) and enters the coin sorting machine, where it is determined whether the coin is a proper coin or not. is returned from the outlet 55.

The coin C1 fed into the coin passage 21 is shown in FIG. 3A.
Once it enters the coin fitting part 25 of the coin stopper 23 as shown in FIG.

Then, due to the weight of the coin C1, the lower end 2 of the fitting part 25
5b is pressed, the coin stopper 23 rotates counterclockwise around the shaft 24, allowing the coin C1 to pass.

When the coin stopper 23 is rotated enough to allow the coin C1 to pass as described above, the stepped portion 33 is moved to the lock lever 30.
It engages with the locking portion 32 of the coin as shown in FIG. 3B and cannot be returned, thereby preventing two or more coins from passing through at the same time even if a plurality of coins are inserted at the same time.

Therefore, even if several coins C2゜C3 are inserted at the same time, the second and subsequent coins C2, C3...
... is held against the upper end 25a of the coin fitting portion 25 of the coin stopper 23, as shown in FIG. 3B.

Further, due to the rotation of the coin stopper 23, its recess 26 is disengaged from the pin 28 at the tip of the arm 27 of the stop release lever 17, and the release lever 17 becomes in a state where it can be rotated.

As described above, the coin fitting portion 2 of the coin stopper 23
During the fall of the coin C1, the edge of the coin C1 hits the inclined edge 53 of the stop release lever restraint member 50 as shown in FIG. It gradually swings counterclockwise about the shaft 51 and moves away so as not to obstruct the passage of the coin C1, and the stop release lever 17 is released from its restraint.

The coin C1 that pushes aside the restraining member 50 and falls is accelerated and collides with the coin abutting portion 20 of the stop release lever 17, and the impact causes the stop release lever 17 to rotate counterclockwise about the shaft 19. Let (
Figure 3B).

At this time, the rotation of the stop release lever 17 is WAY)・2
2, and due to the inertia of its initial movement, the stop release lever 17 is slowly and largely rotated.

The coin C1, which has been rotated by the stop release lever 17 as described above, falls to the back side of the machine body 1 and is collected by a conveyor or the like (not shown).

When the stop release lever 17 rotates counterclockwise, the stop claw 18 engages the ball counter stop plate 1.
It comes off from the stepped portion 13 of No. 1.

Then, the ball counter stop plate momentarily rotates clockwise to the extent that it hits the toe stopper 16, and as shown in FIG.
The stop claw 18 does not engage with the stepped portion 13 even if the upper end of the lever 17 is rotated to its original position by the action of the weight 22.

Therefore, the gear 9 including the ball counter stop plate 11, which has been restrained by the stop pawl 18, and the cam 1
0 a and 10 b are in a state where they can rotate.

As the gear 9 is released from the restraint, the ball counter plays 1 to 5 begin to be rotated by the weight of the pachinko balls, and the stepped portion 13 of the ball counter stop plate 11 moves to the position shown in FIG. 4A.
Rotate until it hits the stopper claw 18 again as shown in FIG.

When the ball counter stop plate 11 rotates once and the stepped portion 13 hits the stop claw 18 of the stop release lever 17 and stops, the gears 9 and 12 also stop, and the ball counter plays 1 to 5 also stop, causing the pachinko balls to stop. The injection stops.

Until this stop, a number of pachinko balls corresponding to the captured coins C1 are ejected from the ejection port 56 into an external saucer or the like.

On the other hand, when the stopper release lever 17 is rotated by the collision of the coin C1, its arm 39 is positioned behind the arm 38 of the return lever 35 as shown in FIG. 3B.

The stopper release lever 17 rotates back clockwise due to the weight of the weight 22, pushes away the stop release lever restraining member 50, and returns to its original position (the state shown in FIG. 3C1 and FIG. 5A).
When the arm 39 returns to the position, the arm 39 separates from the arm 38 and the cam abutment side of the return lever 35 touches the cam 10.
a, the tip 40 of the return lever 35 is located behind the coin stopper 23, and at the same time the auxiliary lever 41 is pushed up by the lock lever 3.
0 to remove the lock portion 32 from the stepped portion 33 of the coin stopper 23.

As a result, the coin stopper 23 rotates clockwise due to its own weight and hangs down, and its recess 26 engages with the pin 28 of the arm 27 of the stop release lever 17 to prevent the release lever 17 from descending. Since the upper end 25a of the coin fitting part 25 of the stopper 23 retreats, the next coin C2 falls to fit into the coin fitting part 25, and the coin stopper 23 is rotated, so that the tip 4 of the return lever 35
0 and temporarily holds the coin C2 in the coin fitting portion 25.

When the cam contact portion of the return lever 35 falls onto the stepped portion of the cam 10a, the tip portion 40 moves diagonally upward and to the right in the figure, allowing the coin stopper 23 to rotate, resulting in the above-mentioned first step. The same effect as in the case of coin C1 is entered.

In a ball lending machine that operates as described above, for example, coin C
By tying a string to the coin passage 21, bringing it into contact with the stop release lever 17, moving it down and pulling it up again, and operating the stop release lever 17 again, you can release pachinko balls without limit. Even if the coin is to be thrown out, in the present invention, the recess 52 of the stop release lever restraining member 50 facing the coin passage 21
Since the upper edge 52A of the coin C is more protruded than the lower edge 52B, even if an attempt is made to pull up the coin C after passing the upper edge 52A, the upper edge 52A of the coin C will be pulled up as shown in FIG. 5B. If the upper end of the coin C hits the edge 52A and is pulled up, the coin C is left in a state where it cannot fall or be pulled up.

Therefore, when the cam 10a makes one revolution after a number of pachinko balls close to the one-shot amount have been thrown out, the arm 39 of the stop release lever 17, which is held down by the coin C as described above, Since the restraining mechanism in which the arm 38 is also pressed (as shown in Figure 3B) is working,
The cam cannot rotate any further, and as a result, the outflow of pachinko balls is stopped.

Therefore, even if an attempt is made to illegally throw out pachinko balls by attaching a string to a coin, the unauthorized operation becomes impossible, and theft of pachinko balls can be reliably prevented.

In addition, the stopper release lever, which unlocks the pachinko ball dispensing mechanism by the impact of the inserted coin, is normally engaged with the recess and is restrained, and when a coin is inserted, the stopper release lever is restrained by the coin to release the restraint. The upper edge of the recessed portion of the member is configured to prevent the inserted coin from moving backwards, and in addition to preventing unauthorized operation of the stop release lever, the same member can prevent the coins from moving backwards.
Therefore, two objectives can be achieved simultaneously without increasing the number of component parts, and the desired objective can be achieved with a simple configuration.

The present invention is not limited to the dispensing mechanism shown in the illustrated embodiment, but can be applied to any type of mechanism in which a dispensing command is issued to the ball counter mechanism by a lever operated by the inserted coin itself. be.
