Description

[Detailed explanation of the invention] (Field of industrial application) Generally, pachinko ball lending machines are installed in pachinko halls and are placed between a large ball lending machine that uses electric means and each pachinko machine. There are ball lending machines that are thin and do not use electrical means.

This proposal relates to a thin ball lending machine that does not use electrical means.

(Prior Art) As is well known, this type of ball lending machine is connected to a star foil that faces the ball passage and engages with pachinko balls in a machine frame in which a ball passage and a coin passage are formed. The machine is equipped with a ball lending mechanism that has a plate that rotates a star wheel a predetermined number of times when activated by a coin inserted into the machine, and when a coin is inserted, the corresponding number of pachinko balls are lent out by swinging the plate. It is becoming more and more like this.

Regarding this, the present applicant has previously proposed a ``Pachinko ball rental machine with a fraud prevention mechanism'' in Utility Application No. 57-54589.

In these conventional ball lending machines, the entire coin passage and most other parts are made of general-purpose plastic or the like because of its good workability.

(Problem to be solved by the invention) In general, a ball lending machine that can be used for a long period of time without malfunctioning or deteriorating in function is extremely convenient for pachinko parlor users and employees. is good.

However, in conventional ball lending machines, the walls of the passageway are scratched by the coins passing through the coin passageway, resulting in malfunctions, such as situations in which balls do not come out even when coins are inserted, or the machine cannot be used continuously. It has the disadvantage that it is easily damaged, cannot be used for a long time, or requires repair many times.

In particular, this type of coin is stopped between the plate and the upper corner of a recess provided in the coin passage, and in order to obtain a greater falling force of the coin, the coin passage is arranged approximately vertically. In a ball lending machine with a straight line in the direction, the falling force of the coin is large, so the corner portions that come into contact with the coin when the coin stops are more abraded.

(Means for Solving the Problems) Therefore, in order to solve the above-mentioned problems, the present invention is designed to engage with pachinko balls by facing the ball passages of a machine frame in which a ball passage and a coin passage are formed. A ball lending mechanism is provided which has a first plate that is interlocked with a star wheel that is rotated by a coin inserted into the coin passageway and temporarily stops the coin in the passageway, In a ball lending machine in which the coin passage portion has a recess that serves as a detour for the coin, and the coin is stopped between the upper corner of the recess and the first plate, the upper corner of the recess is made of abrasion-resistant material. Constructed of wood.

(Effects of the invention) Since the present invention has the above-described structure, the wear resistance of the upper corner of the recess of the coin passage is significantly improved, and there is no need for repair and there is no deterioration in function without malfunction. It is possible to provide a ball lending machine that can be used for a long period of time, and therefore, the person who uses this machine is characterized by being able to manage the pachinko parlor smoothly and save costs.

(Example) The embodiments shown in the drawings will be described below.

FIG. 1 is a front view of the proposed pachinko ball rental machine with the cover removed. This ball lending machine has a fraud prevention mechanism in addition to the ball lending mechanism.

First of all, to explain the mechanism, 1 is the machine frame, and on both sides there are ball passages 2 and coin passages 3.
is 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 cam gear 7 via an intermediate gear 6, so that the cam gear 7 rotates in accordance with the rotation of the star wheel 4. I'm starting to do that.

A cam 8 is integrally provided on the front surface of the cam gear 7, and a protrusion 9 is integrally provided on the back surface. The cam 8 and the projection 9 therefore rotate together with the gear 7.

The cam 8 has 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 .

Reference numeral 17 denotes a first plate, and a curved recess 18 surrounding the cam 8 is formed in the first plate 17 . Two opposing protrusions 19 and 20 protruding toward the cam 8 are formed in the curved recess 18 .

Further, a coin receiving portion 21 that projects into the coin passage 3 is formed on the first plate 17 .

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

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

On the wall surface 3a of the coin passage 3 corresponding to the coin receiving section 21, a recess 3b that serves as a detour for coins extends downward from the corner 3d. Pin 6 made of abrasive material
0 is inset (see Figure 8).

Note that the pin 60 may be made of steel, fine ceramics, wear-resistant plastic, or the like.

Reference numeral 23 denotes a second plate, which is swingably mounted on a pivot 24.

The second plate 23 is provided with upper and lower protrusions 25 and 27, at least one of which projects into the coin passage, above the point in the coin passage 3 where the coin receiving part 21 of the first plate 17 protrudes.

Furthermore, a protrusion 26 is formed on the back surface of the first plate 17, and the second plate 23 is
It is provided with a recess 28 that engages and disengages with this protrusion 26.

Reference numeral 29 denotes a third plate, which has an approximately L-shape as a whole consisting of a horizontal portion 30 and a vertical portion 31, and has a horizontal portion 30 and a vertical portion 31.
It is mounted so that it can swing. The tip 32 of the horizontal portion 30 is connected to the protrusion 9 on the back side of the cam gear 7.
The vertical portion 31 is provided with a recess 33 that engages and disengages with the protrusion 26 of the first plate 17, and a hook portion 34 is formed below the recess 33. .

40, a fourth plate; this fourth plate 40 is swingably mounted on a pivot 41;

The fourth plate 40 has a tip portion 42 that can protrude below a portion of the coin passage 3 where the coin receiving portion 21 of the first plate 17 protrudes.
Further, the third plate 29 is provided with two protrusions 43 and 44, which are capable of coming into contact with and disengaging from the hook 34, at a location facing the hook 34.

Note that the first, third, and fourth plates 17, 2
9 and 40 are weights 50 and 5 attached respectively.
1 and 52, and the second plate 23 is forced clockwise by the action of the second plate 23, and the second plate 23 is forced to move toward the pivot 24 by its own weight.
It is starting to hang down from the top.

In addition, 53 is a regulating member to ensure the engagement between the star foil and the pachinko balls, 54 is a tank for temporarily storing the released pachinko balls, and 55 is the fourth 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 fourth plate 40.

Next, the state of use of the ball lending machine as described above will be explained.

First, let us explain the case where there is no fraudulent activity: (i) Before a coin is inserted, the protruding portion 19 of the first plate 17 contacts the small diameter portion 13 of the cam 8 and engages with the first stepped portion 10. Therefore, the cam gear 7 is in a non-rotatable state, and the star wheel 4 also does not rotate, so the pachinko balls do not flow down. In this state, the second plate 23 has its recess 28 engaged with the protrusion 26 of the first plate, and the third plate 29, of which only the lower protrusion 27 protrudes into the coin passage 3, has its vertical portion 31 engaged. The rib 3 forming the coin passage 3
c, and the tip 32 of the horizontal portion 30 enters the back side of the cam gear 7. The fourth plate 40 has an upper edge of its protrusion 43 that is connected to the third plate 2.
It comes into contact with the lower edge of the hook portion 34 of No. 9 and cannot be rotated clockwise, and its tip 42 does not protrude into the coin passage 3.

(ii) When coin a is inserted, coin a passes through the upper protrusion 25 of the second plate and hits the lower protrusion 27, and as shown in FIG.
3 in the counterclockwise direction, and the second plate 2
After the engagement between the recess 28 of No. 3 and the protrusion 26 of the first plate 17 is released, the coin receiving portion 21 of the first plate 17 is further abutted and pushed down.

Note that when the second plate 23 swings counterclockwise, the upper protrusion 25 protrudes into the coin passage 3, and when coins are continuously inserted, the next coin a' is It comes into contact with the upper protrusion 25 to prevent it from falling.

Further, the rotation of the second plate 23 in the clockwise direction after the coin a has passed is caused by the rotation of the second plate 23 in the clockwise direction.
3a is regulated by coming into contact with the protrusion 26 of the first plate 17 (see Fig. 3), and the upper protrusion 2
5 and the next coin a' are never disengaged.

(iii) The engagement between the concave portion 28 of the second plate 23 and the protrusion 26 of the first plate 17 is released, and the coin a pushes down the coin receiving portion 21 of the first plate 17, so that the first plate 17 moves counterclockwise. The protrusion 20 of the curved concave portion of the cam 8
Since the coin a is restrained from swinging by coming into contact with the middle diameter portion 14, the coin a is supported by the coin receiving portion 21 of the first plate and the corner portion 3d of the coin passage 3 and comes to a stop. figure). Further, by the counterclockwise rocking of the first plate 17, the engagement between the protruding portion 19 and the first step portion 10 of the cam 8 is released, thereby allowing the cam gear 7 to rotate. Therefore, the pachinko balls engage with the star foil 4 and flow down while rotating it.

In addition, the coin a is placed between the coin receiving part 21 and the corner part 3d.
As will be explained later, the reason for temporarily stopping the
This is to wait until the tip end 42 of the plate 40 is set so as to face the passage 3.

(iv) As the pachinko balls flow down and the star wheel 4 rotates, the cam gear 7 also rotates clockwise, and the protrusion 9 on the back side of the gear rotates on the third plate 2.
When it reaches the tip 32 of the horizontal part 9, it comes into contact with it and pushes up the horizontal part 30.

(v) When the horizontal portion 30 is pushed up as shown in FIG.
When the protruding part 43 of the fourth plate 40 is released from contact with the protruding part 43, the hook part 34 pushes the other protruding part 44 of the fourth plate (see FIG. 2), so the fourth plate 40 swings clockwise. The tip portion 42 protrudes into the coin passage 3, and the third plate 2
9 recesses 33 surround the projections 26 of the first plate 17 .

(vi) As shown in FIG. 4, when the cam gear 7 further rotates and the protrusion 9 on its back surface disengages from the tip 32 of the third plate horizontal portion 30, the third
The plate 29 swings clockwise and tries to return to its original position, but at this time the third plate 29
The hook portion 34 engages with the protruding portion 43 of the fourth plate 40, and the swinging of the third plate 29 is restricted.

(vii) As the cam gear 7 further rotates as shown in FIG. The coin a, which had been supported by the coin receiving part 21 and the corner part 3d, falls through the detour path 3b and pushes down the tip 42 of the fourth plate 40. , are discharged outside the machine from the discharge port 3e (Fig. 1).

When the coin a presses down the tip 42 of the fourth plate 40, the fourth plate 40 swings counterclockwise, thereby causing the protrusion 43 of the fourth plate to connect with the hook 34 of the third plate. Since the engagement is released, the third plate 29 rotates clockwise and returns to its original position. As a result, the concave portion 33 of the third plate is unenclosed from the protrusion 26 of the first plate 17, and the first plate 17 is placed in a state where it can swing clockwise. Further, the protruding portion 43 of the fourth plate 40 comes into contact with the hook portion 34 of the third plate 29, so that the fourth plate 40 is in the same state as the original position.

(viii) When the cam gear 7 rotates further and the first stage part 10 of the cam 8 reaches the protrusion part 20 of the first plate 17, it pushes it to the right in the figure, so the first plate 17 swings clockwise,
Another protrusion 19 abuts the large diameter portion 15 of the cam 8.

(ix) The cam gear 7 further rotates and the first plate 1
As shown in FIG. 6, when the protrusion 19 of the cam 8 comes into contact with the medium diameter part 14 of the cam 8 and falls into the small diameter part 13, the first plate 17 further swings clockwise.
As a result, the contact between the protrusion 26 and one edge 23a of the second plate 23 is released, and the second plate 23 is released.
3 swings clockwise and returns to its original position. When the next coin a' is present, the second plate 23 returns and the contact between the upper protrusion 25 and the coin a' is released, and the coin a' falls, as explained above. The effect will be repeated.

As explained in (i) to (ix) above, if there is no fraudulent activity, the cam gear 7 rotates once when a coin is inserted, and a corresponding number of pachinko balls are played. Pachinko balls are automatically lent out, and even if coins are continuously inserted, there is a tank 54, so pachinko balls can be lent out smoothly. Note that the actual time from when coin a is inserted until it is ejected from the machine is about 0.5 seconds.

Next, we will explain the effects in the event of fraudulent activity.

If the second plate 23 is swung counterclockwise and the coin receiver 21 of the first plate 17 is pushed down using a wire or the like without inserting a coin as a fraudulent act, (i) a fraudulent act; The cam gear 7 rotates and a certain amount of pachinko balls flow out in the same way as in the case where there is no pachinko ball.

(ii) However, as the cam gear 7 rotates, the third plate 29 swings counterclockwise, and as shown in FIG.
When the cam engages with the protrusion 43 of the cam, the engagement is not released because no coin is actually inserted, and the recess 33 of the third plate is not enveloped by the protrusion 26 of the first plate. The corner portion 16 of the large diameter portion 15 of No. 8 reaches the protrusion 20 of the first plate 17, and as shown in FIG. Also, the protrusion 26 of the first plate 17 is connected to the recess 3 of the third plate 29.
3, the first plate 17 does not swing, and therefore the rotation of the cam 8 is stopped by the protrusion 20, which also stops the rotation of the star wheel 4. The ball's flow is stopped.

(iii) Furthermore, even if you operate the second and first plates 23, 17 as before with a wire or the like and then try to operate the fourth plate 40, the operation of the fourth plate 40 will not be possible due to its protrusion. From the time when the contact between the hook portion 34 of the third plate 29 and the corner portion 16 of the cam 8 is completed, the corner portion 16 of the cam 8 is brought into contact with the first plate 17.
This has to be done while reaching the protrusion 20 of the camera, which is virtually impossible considering that the time required for this is extremely short.

(iv) Also, once the protrusion 26 of the first plate 17
When the star foil 4 is engaged with the concave portion 33 of the third plate 29, the weight of many pachinko balls is on the star foil 4, so this engagement is quite strong and ends up pushing down the tip 42 of the fourth plate 40. Eventually, it will become impossible to release. Furthermore, when the first plate 17 attempts to swing clockwise, the projection 26 causes the third plate 29 to rotate counterclockwise, so that the projection 26 engages with the inner part 33' of the recess 33. This will make the engagement 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 fourth plate 40
If the user commits the same fraudulent act as before by fixing the coin with wire or any other means so that the tip 42 does not protrude into the coin passage 3, (i) the cam gear will be removed as in the case where there is no fraudulent act; 7 rotates and some pachinko balls flow out.

(ii) However, when the cam gear 7 rotates and its protrusion 9 reaches the horizontal end 32 of the third plate 29 as shown in FIG. 3 and attempts to push it up, the fourth plate 40 cannot rotate. Therefore, the counterclockwise rocking of the third plate 29 is restricted by the hook portion 34 coming into contact with the protruding portion 44 of the fourth plate 40 as shown by the imaginary line in FIG. Become.

(iii) Therefore, the rotation of the cam gear 7 is stopped because its protrusion 9 is in contact with the horizontal end 32 of the third plate, and thereby the rotation of the star wheel 4 is also stopped. Therefore, the flow of pachinko balls is stopped.

(iv) Furthermore, even if the fixation of the fourth plate 40 is released after that, the hook portion 34 of the third plate and the protruding portion 43 of the fourth plate 40 will engage with each other. It would operate in the same way as in the case of fraud mentioned above.

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 second plate or the coin receiving part 2 of the first plate
Since the bottom surface of the coin comes into contact with the top surface of the coin and acts as a stopper, such fraud is naturally prevented.

As explained above, this ball lending machine automatically lends out the designated pachinko balls if the coins are inserted properly without any fraudulent activity, and if the coins are not inserted properly due to fraudulent activity, the machine automatically lends out the specified pachinko balls. This device has the function of stopping the rental of balls, but in the present invention, since the corner portion 3d, which is most susceptible to wear in such a ball rental machine, is made of a wear-resistant material, none of the above can be avoided. The corner portion 3d is not worn even by the above actions, and therefore a ball lending machine that does not malfunction can be provided.
