Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a game ball rental machine such as a pachinko ball rental machine, and more particularly to an abnormal outflow prevention device that can prevent players from stealing rental balls by illegal means.

i Recently, in pachinko parlors, it has been widely adopted to install vertically slim-shaped ball lending machines between adjacent pachinko machines for the convenience of players. Theft of more than the specified number of rented balls through illegal means is a frequent occurrence, requiring an increase in the number of inspectors, and causing various troubles over how to deal with theft as it is difficult to confirm the situation. Because of these problems, the development of devices that can easily prevent fraud has become a concern for those involved.

) Normally, a typical method for illegally stealing rental balls is to punch a small hole in the periphery of a designated coin, such as a 100 yen coin, and thread a thread such as a "Tegusu" through the hole, and then turn the 100 yen coin into a ball. One example is to suspend the ball from the coin slot of the rental machine to an appropriate position so that the ball payout device can be operated continuously.

To counter such fraudulent means, proposals include installing a non-return mechanism in the coin guide path, and forming the guide path in a zigzag shape so that the hanging thread cannot easily pass through. However, they are not widely used because they require extensive modifications, which increases the cost of the equipment, and they are difficult to apply to existing ball lending machines. The reality is that it is not.

In view of the fact that conventional devices of this type have various practical drawbacks, the present invention can be easily applied to conventional ball lending machines by simply adding an electric circuit. We have now devised a new abnormal outflow prevention device that is capable of reducing device costs and ensuring reliable operation.

The specific contents of the apparatus of the present invention will be explained in detail below with reference to the accompanying drawings.

Figure 1 is a schematic diagram functionally showing the structure of a pachinko ball rental machine, and it shows the difference between genuine coins and bad coins, and whether coins inserted from coin slot 1 are regular coins or regular coins. When only a predetermined regular coin is selectively sent from the coin discriminator 2, a passage 3 guides the coin at the appropriate timing, and a coin discriminator 2 that determines whether the coin is genuine or not. It consists of a coin storage box 4 for storing coins, and a ball payout device 5 that is activated when a predetermined coin passes through the passage 3, and is placed between two adjacent pachinko gaming machines.

The rental ball payout device 5 is equipped with an electromagnetic solenoid 6 as a trigger mechanism, and when the solenoid 6 is instantaneously energized once, a predetermined number of rental balls are continuously flowed out. One is the energized/deenergized type, in which the balls flow out continuously without interruption if the energization is maintained, and the other is the energized type, in which only a predetermined number of balls flow out regardless of whether the energization is maintained. There is something.

The above-mentioned ball lending machine is equipped with two coin detectors 7 and 8 at appropriate locations in the coin passage 3, and is formed by the coil 6s of the electromagnetic solenoid 6 and each output part of the coin detectors 1 and 8 as elements. The control system includes an electric circuit shown in FIG.

The coin detectors 7 and 8 are, for example, light-actuating microswitches that detect the passing of a predetermined coin using a dog or a lever, and emit an electric signal in an instantaneous time period of about a fraction of a second. It has become.

The coin detector 7 generates an electric signal when the switch is closed, and the coin detector 8 generates an electric signal when the switch is open.

It should be noted that the coin detector I and the coin detector 8 must be configured so that there is a difference in the operating time of each switch, and the coin detector 7 operates faster than this, for example, The coin detector 8 is activated after a delay of about seconds.

The coin detector 8 is not limited to the coin passage 3, but can achieve its purpose by installing it at an appropriate position on the route where a given coin circulates, including the passage. It is particularly preferable to select a position where, when a hanging coin is inserted, it will not be pulled up as shown in the first figure.

An example of an electric circuit of a ball lending machine having such a structure will be explained with reference to FIG. 2. This circuit connects the coil 6s of the electromagnetic solenoid 6 and the coil of the electromagnetic relay 9 attached in relation to the solenoid 6 in parallel. The parallel circuit is connected to the power supply when the normally open contact of the coin detector 7 is closed, and also when the normally closed contact of the coin detector 8 is closed and the electromagnetic relay 9 is connected. The wiring is made so that it is connected to the power supply when the self-holding instant action contact 9c is closed.

The electromagnetic relay 9 connects the time-limited closing contact 9a to the contact 9c.
This is a so-called timing relay, which has a time limit until the contact 9a closes after the coil is energized, and is set to a time slightly longer than the difference in operating time between the coin detector 7 and the coin detector 8. I'm letting you do it.

[Then, the time-limited closing contact 9a operates an alarm 10 such as an indicator light.

In FIG. 2, 11 is a reset switch.

Next, to explain the operating mode of the above-mentioned device, a well-intentioned player who needs a rental ball inserts a predetermined coin into the coin slot 1.
When the coin detector 7 is inserted, the switch of the coin detector 7 is instantaneously closed, which excites the electromagnetic coil 6s and instantaneously activates the electromagnetic solenoid 6, so that a predetermined number of rented balls flow out.

At the same time as the electromagnetic coil 6s is excited, the electromagnetic relay 9 is energized.
This biased state is self-maintained by closing contact 9c.

However, the inserted coin that activated the coin detector 7 opens the coin detector 8 earlier than the predetermined time period for the contact 9a of the electromagnetic relay 9 to activate, so the electromagnetic relay 9 returns to deactivation. Therefore, it can be seen that the alarm 10 is not fully activated and the coins are inserted normally.

On the other hand, a coin is suspended by a thread, and the coin detector 7
Considering the case where there is a fraudulent act such as activating the coin detector 8, the electromagnetic relay 9 will remain energized unless the coin suspended by the thread activates the coin detector 8.
It is possible to close the contact point 9a after a predetermined time period has elapsed, and use the alarm 10 to notify that an unauthorized operation has been performed.

Even if the coin detector 8 is activated after the coin detector 7 is activated by a hanging coin, if the time required for this activation is longer than the set time limit of the electromagnetic relay 9, the alarm 10 will be activated in a short time. However, it is easy to confirm as it notifies the occurrence of fraudulent operations, and by making it impossible to lift the coin as described above, it is possible to prevent fraudulent activities from occurring with just one fraudulent operation. It can't be done.

It should be noted that the circuit shown in the second figure is effective when the ball lending machine is of the biasing type described above.

Further, since a ball rental machine is usually equipped with a rental display lamp that is turned on when the ball is being rented and turned off when the ball is borrowed, this rental display lamp can also be used as a substitute for the alarm 10.

In this case, the contact 9a of the electromagnetic relay 9 should be of a normally closed structure as shown by the broken line in Fig. 2, and the lending indicator lamp can be turned off to prevent well-intentioned users from inserting coins. It is convenient to be able to do so.

Next, explaining the circuit shown in Figure 3, this device is suitable when the ball lending machine is of the above-mentioned energizing/deenergizing type, and a time-limited normally closed contact 9b is added to the electromagnetic relay 9. At the same time, the contact 9b is connected to the coil 6s of the electromagnetic solenoid 6.
This is an additional circuit that is connected in series to the .

According to this circuit, even if the coin detector 7 is activated continuously based on unauthorized operation, the electromagnetic relay 9 continuously opens the contact 9b after a predetermined time limit, so the electromagnetic solenoid 6 is forcibly deenergized. After a predetermined number of rental balls have been leaked only once, illegal leakage of rental balls is reliably prevented.

Note that this circuit system can of course be applied to an energized ball lending machine, and the continuous operation of the coin detector 7 keeps the electromagnetic solenoid 6 energized, resulting in unnecessary power consumption and This is effective in preventing overheating.

The present invention has the above-described configuration and operation, and by assembling two simple electrical parts, the coin detector 8 and the electromagnetic relay 9, it is possible to prevent abnormal outflow of balls, and the cost for improvement is reduced. It can be installed very low and can be easily applied to existing ball lending machines, making it highly versatile.

Moreover, the present invention electrically detects fraudulent situations, regulates abnormal outflow of rented balls, and issues a monitoring signal.
Its operation is reliable, and it does not cause any malfunction even if a fraudster performs quick operations.As it satisfies the requests of those involved, its practical value is extremely high, and it is truly outstanding. This is a device to prevent abnormal outflow of balls from a ball rental machine.
