Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a ball lending machine that automatically lends out pachinko balls, and in particular, it is designed to prevent pachinko balls from being stolen by external operations. The present invention relates to a fraud prevention mechanism for an automatic ball lending machine that has double operation to further increase reliability.

(Prior Art) This type of ball rental machine has come to be rented out in the form of a vending machine as pachinko parlors seek to save labor. Therefore, the supply and collection of pachinko balls are all integrated into a centralized control system, and the system is installed between pachinko machines, making it thinner without using electrical means, saving space, and handling pachinko balls at a nearby location. We are planning to make it available for rental and provide services to our customers.

However, with this type of pachinko ball lending machine, it has been possible for an outsider to illegally manipulate the machine and steal the pachinko balls.

The present invention has been made for the purpose of providing an anti-tampering mechanism for an automatic ball lending machine that is configured with a dual mechanism that can reliably prevent pachinko balls from being stolen by unauthorized operations from outside.

(Problems to be Solved by the Present Invention) The present invention not only accurately counts the number of pachinko balls with respect to the inserted coin, but also restrains the ball counting mechanism that is activated by the inserted coin and starts counting the balls. To provide an anti-fraud mechanism for an automatic ball lending machine in which a mechanism for preventing pachinko balls from being stolen due to unauthorized operation from the outside is surely prevented by providing dual means for releasing the mechanism and controlling the timing thereof.

(Means for Solving the Problems) The present invention includes a sprocket wheel that engages with pachinko balls supplied to a ball path to count rotations, and an engaging stepped portion that is integrally provided with the sprocket wheel. A sprocket wheel with a cam provided with a control cam, and an intermediate lever having a stop pin that engages with the engagement step of the sprocket wheel and restrains the sprocket wheel with a cam, and is rotated by the passage of an inserted coin. The coin repeating lever is provided with a vertical groove for limiting the rotation range of the intermediate lever and a horizontal groove for canceling the restriction, and is provided with an activation lever for rotating the intermediate lever with the weight of the inserted coin, and the activation portion The automatic automatic machine is equipped with a check lever that is rotated by the weight of an inserted coin and releases the restraint of the activation lever by removing the check pin from the engagement stage. This is a fraud prevention mechanism for ball rental machines.

(Function) The coin toss lever that collides with the inserted coin in the counterclockwise direction retains the next coin in its locking part, and also releases the lead pin of the intermediate lever that was engaged in the vertical groove of the non-operating special lead groove. engages its horizontal axis.

Next, the inserted coin contacts the coin receiving portion of the activation lever, rotates counterclockwise by its weight, and descends. The activation lever is made of a sprocket wheel with a cam that satisfies the distance required for the activation pin to rotate the intermediate lever that engages with the engagement groove, and for the stop pin of the intermediate lever to disengage the engagement step of the control cam. The restraints are lifted.

The check pin of the lowered starting lever passes through the inclined groove of the check lever and engages with the engagement step, thereby restraining the starting lever from returning to its original state.

The stop pin, which slides into contact with the curve of the control cam, causes the lowered starting lever to descend one more step, causing the temporarily held coin to fall into the abutting portion of the check lever.

The check lever rotates counterclockwise against the biasing force due to the weight of the falling coin, removes the check pin that was engaged with the engagement stage, and comes into contact with the inclined groove side, and the coin is ejected.

The stop pins that slide in contact with the curve of the control cam are successively pushed up, and the starting lever, which has been released from the check lever, rises together with its restoring force, and the stop pin is again pushed up to the engagement step. Until one cycle is completed after engagement, a predetermined number of pachinko balls are counted and released for each inserted coin.

It is prevented from falling until the end.

The lead pin 84 that is engaged with the horizontal groove 64b of the lead groove 64 due to the rotation of the coin series lever 6 is interlocked with the starting pin 91 that is engaged with the engagement groove 83 since the rotation range of the intermediate lever 8 has been released. The activation lever 9 is lowered by the weight of the coin S ₁ that has come into contact with the coin receiving portion 93 , and the stop pin 81 of the intermediate lever 8 interlocked with this is moved to the engaging stepped portion 5 of the control cam 52 .
1 is removed, the restraint of the sprocket wheel 5 with a cam is released, and rotation is started by the weight of the pachinko balls supplied to the meandering ball path 2a. At this time, the check pin 94 of the activation lever 9 that has been lowered passes through the check groove 11 of the check lever 10, which is biased clockwise when not in operation, and is engaged with the engagement step 12.

(See Figure 2) Immediately before the cam-equipped sprocket wheel 5 rotates 1/4, the stop pins 81 and 82 that slide into contact with the control cam 52 are pushed down, and the activation lever 9 that interlocks with the intermediate lever 8 is further pushed down. Check lever 10 for coin S ₁ that was temporarily held after descending.
The coin is dropped onto the coin contact portion 15 of the coin. The check lever 10 is rotated counterclockwise by the weight of the coin S ₁ about the pivot 13 as a fulcrum against the urging force of the weight 14, and the check pin 94, which has disengaged its engagement stage 12, is moved into the check groove 11. It abuts against the inclined portion 11a. (See Figure 3) Just before the sprocket wheel 5 with a cam makes a 1/2 turn, a contact portion 7 is formed on the semicircumference of the latch cam 53 that rotates integrally with the sprocket wheel 5 with a cam.
The latch lever 7 with which the latch lever 2 is abutted moves the latch lever 7 in the direction to remove the engaged latch pawl 63 from the latch stage 71.
It rotates against the restoring force of 3, and the engagement of the coin series toss lever 6 is released, and the coin series toss lever 6 stands by for restoring. (See FIGS. 4 and 5) On the other hand, the check pin 94 of the starting lever 9, which is raised by the restoring force, is connected to the inclined portion 1 of the check lever 10.
The coin abutting portion 15 of the check lever 10, which slides on the check lever 1a and rotates counterclockwise by the weight of the coin _S1 , causes the coin _S1 to fall and be ejected. (See Fig. 6) The control cam 52 rotates once and the engagement step 5
Immediately before the stop pin 81 engages with 1,
The lead pin 84 reaches the upper part of the vertical groove 64a and restores the coin toss lever 6 whose engagement with the latch pawl 63 has been released first, but it comes into contact with the notch of the latch cam 53 as shown in FIG. However, at the same time as the repeated coin toss lever 6 and the restoring pin 66 are positioned in the half-moon-shaped recess 54a of the repeated coin toss cam 54, the coin toss lever 6 is brought into the restoring state and at the same time the cam-equipped sprocket foil 5 is restrained. One cycle of counting for one pachinko ball coin is completed, the next coin _S2 falls, and the above cycle is repeated. (Refer to Figures 7 and 8) An anti-tampering mechanism is added to an embodiment of the present invention, and even if an attempt is made to move the starting lever 9 alone due to fraudulent activity, the intermediate lever 8 is provided with a control mechanism that controls the rotation range. The lead pin 84 is engaged with the vertical groove 64a of the lead groove 64 provided on the coin repeating lever 6, and the starting pin 91 provided on the starting lever 9 is engaged with the intermediate lever 8. Since the pachinko ball is engaged with the groove 83, in this state the intermediate lever 8 and the starting lever 9 interfere and the restraint of the cam-equipped sprocket wheel 5 cannot be released, so it is impossible to steal pachinko balls by unauthorized operation. (See Figure 9.) Furthermore, in Figure 10, even if it were possible to sequentially move the coin toss lever 6, intermediate lever 8, and start lever 9 by fraudulent means, the coin input of the check lever 10 would not be possible. If the inserted coin is not positioned on the contact portion 15, the check pin 94 of the starting lever 9 will be engaged with the engagement stage 12 of the check groove 11 provided in the check lever 10, resulting in a locked state, and the sprocket wheel 5 with cam will be in a locked state. Approximately 1/3 of the balls will be ejected and rotated, and that amount of pachinko balls will be ejected, but pachinko balls cannot be stolen by repeated unauthorized operations.

(Effects of the Invention) As the fraud prevention function of the present invention, firstly, in order to release the restraint of the cam-equipped sprocket wheel, it is necessary to release the rotational restriction of the intermediate lever having the stop pin, so the condition is that coins must be thrown repeatedly. Since the starting lever is configured to operate only when the lever is rotated, even if the starting lever is operated by itself due to unauthorized operation, the intermediate lever and the starting lever will interfere, so the cam-equipped sprocket cannot be rotated. I can't move it.

Second, even if the coin toss lever, intermediate lever, and start lever are moved sequentially by unauthorized operation, each lever will not work properly unless the coin actually inserted falls from the start lever to the check lever. Since the check lever is locked immediately, repeated unauthorized operations cannot be performed.

As described above, the effect of the invention which has a double prevention mechanism that actually allows pachinko balls to be stolen by unauthorized operation from the outside is a fraud prevention mechanism for automatic ball lending machines that exhibits effects not previously available.
