Abstract

PURPOSE:To prevent misjudgement due to the up-and-down motion of the same coin by a string, etc., by detecting all the repeated up-and-down motions or the like as an error by detecting that two switches are turned ON by turn. CONSTITUTION:When a regular medal 50 is thrown in, and in addition, the medal 50 reaches a medal path 40, the medal 50 is confirmed for its presence by a first switch 10. Then, when it is detected that the medal 50 was thrown in and the first switch 10 was turned into ON-state, subsequently, it is detected whether a second switch 20 is in OFF-state or not in this state. After it is detected that the second switch 20 is in OFF-state, next, it is detected whether the first switch 10 was turned into OFF-state or not. Thus, the misjudgement due to the up-and-down motion of the same coin by a string, etc., can be prevented.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to a device for determining passage in a normal direction, and more specifically, to a device for determining whether coins are inserted into a vending machine or the like, or various game machines using medals, such as a slot machine. The present invention relates to a normal direction passage determining device for determining whether coins, medals, etc. have been properly inserted when inserting medals into a combination type pachinko machine, a mahjong type pachinko machine, or the like.

[Prior Art J] A variety of vending machines and various game machines that use coins, medals, etc. have been provided in the past.

If coins, medals, etc. are always inserted correctly in these various devices, there will be no problem, but there are cases where counterfeit coins are inserted or fraud is committed when inserting coins. was.

If counterfeit coins are inserted here, it is sufficient to eliminate them using a selector such as coins or medals.

However, despite using the correct coin or medal, for example, by attaching a string to the medal, etc., and pulling or releasing the string, the medal, etc. can be inserted into the switch part for detecting the insertion of the medal, etc. By moving the coins up and down, fraud has also been carried out in which it is determined that a large number of coins have been inserted, even though they have not actually been inserted.

The following measures can be considered to prevent such fraud.

In other words, the purpose is to mechanically prevent such fraud and the like, and to prevent the inserted medals from running backwards through the medal path communicating with the insertion hole.

[The problem that the invention seeks to solve However, forming it in this way.

Sorting medals, etc. that are subject to restrictions such as size or installation location in automatic vending machines or gem machines 921
In this case, the entire device became larger and more complicated, which caused failures.

Therefore, the present invention takes into account the complexity of mechanically detecting unauthorized insertion and the high number of failures, etc., and the device itself is equipped with two switches, and it is detected that these two switches are turned on sequentially. By doing this, if the same coin or medal is moved up and down repeatedly, it will be detected as an error. By moving the same coin or medal, etc. up and down with a string, it will appear as if multiple coins have been inserted. It is an object of the present invention to provide a normal direction passage determination device for preventing determinations that result in inappropriate results.

[Means to solve the problem] One aspect of the present invention is to solve the above-mentioned problems.

A first switch passage detection means and a second switch passage detection means are provided in each of the first switch and the second switch arranged at an interval shorter than the length of the object in the measurement direction, and the first switch passage detection means The first switch is set to O.
When it is detected that the second switch has risen due to N, the second switch passage detection means detects that the second switch is OFF, and the first switch passage detection means detects that the second switch is OFF.
Judgment that determines that the detected object has passed in the normal direction when the second switch passage detection means detects that the second switch is ON when it is detected that the switch has fallen due to OFF. It is characterized by having a means.

[Example J Embodiments of the present invention will be described below according to illustrated examples.

FIG. 1 shows a medal passage 40 for detailed explanation of the present invention.
FIG. 2 is a schematic diagram showing a case where two switches 10 and 20 are provided in the medal passageway 40, and FIG.
FIG. 3 shows the ON and OFF states of the two switches 10 and 20, and FIG.
This figure shows a flowchart for detecting that a pass has passed normally.

First, the general structure of the present invention will be explained in accordance with FIG.
The switch 20 is provided nearby.

The slot 41 is a hole into which the medals 50 are inserted, and is usually exposed to the outside of a vending machine or a game machine (not shown).

Further, the selector 30 determines whether or not the inserted medals 50 or coins are genuine coins. If the selector 30 determines that the coins are counterfeit coins, a cancellation hole (not shown) is selected. It will be canceled.

Therefore, in the present invention, of the inserted coins or medals 50, only genuine coins reach the first switch 10 and the second switch 20.

Here, the first switch IO and the second switch 20 are arranged at an interval shorter than the diameter of the inserted medal 50. Therefore, when the inserted medal 50 moves from the first switch 10 to the second switch 20, a state occurs in which both switches 10 and 20 detect the medal 50.

Next, according to FIG. 2, the ON/OFF states of the first switch 10 and the second switch 20 as the medal 50 moves will be explained.

First, the state shown in FIG. 2(A) is that the first switch lO
This shows a case where the second switch 20 is also turned on while the switch is turned on, and after the first switch lO is turned off, the second switch 20 is turned off. In such a case, the inserted medal 50 is first detected by the first switch 10, this first switch 10 is turned on, and while maintaining this ON state, the second switch 20 is also turned on. and furthermore, the first
The switch 10 is turned OFF, and then the second switch 20 is turned OFF.
This figure shows a state in which the medals 50 and the like fall downward due to turning OFF.

Therefore, the case shown in FIG. ff12 (A) indicates that the medal 50 has moved in the normal direction, that is, has been correctly inserted.

Further, FIG. 2(B) shows a case where the second switch 20 does not sense anything from the time when the first switch 10 is turned on until it is turned off. in this case,
It is possible that a coin or medal 50, etc., is fished with a string or the like and lowered, and although the first switch 10 detects the coin or medal 50, the coin or medal 50 is picked up again before being detected by the second switch 20. This shows a case where the problem occurs.

Therefore, the case shown in FIG. 2(B) is a case where some kind of fraud has been committed.

In addition, the state shown in FIG. 2(C) is that the first switch lO
is not detected at all, and only the second switch 20 is turned OFF.
This shows the case of moving from N to OFF. In such a case, hang a coin or medal 50 with a string, lower the coin or medal 50 until it passes the first switch 1O and the second switch 2o, and then hang the coin or medal 50 slightly. , and the coin or medal 50 turns only the second switch 20 on.
This shows the case where the switch is turned OFF and moved downward again.

Therefore, the state shown in FIG. 2(C) is also a case where some kind of fraud is being committed.

In the state shown in FIG. 2(D), the second switch 20 is once turned ON, and before this second switch 20 is turned OFF, the first switch IO is turned ON and the second switch 20 is turned OFF. The first switch 10 is turned OFF after
This shows the state of F. This state is a completely opposite detection to that shown in FIG. This shows the movement of the switch when lifting a coin so that it reaches . Therefore, in this case as well, some kind of fraud is being committed.

The state shown in FIG. 2(E) is such that the first switch 10 is once turned ON and the second switch 10 is turned ON and OFF before the first switch 10 is then turned OFF. It shows the condition. This situation can be considered as a case where a coin or medal 50 is hung with a string, and the hung coin or medal 50 crosses the first switch IO and reaches the second switch 20, but continues to move downward. Immediately after reaching the second switch 20, it is pulled upward again,
This shows a state in which the second switch 20 is turned off first, and then the first switch 10 is turned off as well.

In this case as well, some kind of fraud was committed.

Furthermore, in the state shown in FIG. 2(F), which is the opposite of the state shown in FIG. 2(E), the second switch 20 is turned on and the first switch lO
This figure shows a case where the switch is turned ON and OFF. In this case, conversely, the first switch lO1, the second switch 2
Medal 5 once moved downward so as to pass 0
0 gradually, first reaching the second switch 20, then lifting it up a little further, detecting the presence of the medal 50 at the first switch 10, and then lowering it downwards as it is, so that the first switch 10 This shows a state in which the coin or medal 50 is no longer detected by the second switch 20 after the medal 50 is no longer detected. Therefore, it is considered that some sort of fraud was committed in this situation as well.

That is, among the various combinations of operation of the first switch 10 and the second switch 20 shown in (A) to F) of FIG. 2, only the case shown in FIG. ．． Otherwise, it is considered that coins were inserted and passed, and in all other cases, it can be considered that some kind of fraud was committed. Therefore, Fig. 2(B)
In the cases shown in (F), it is desirable not only to not count, but also to output that some kind of fraud has been committed.

Next, referring to FIG. 3, the determination means of the normal direction passage determination device according to the present invention will be explained.

First, it is assumed that a regular medal 50 is inserted after this regular direction passage determining device becomes operational.

What if the medal 50 is not a genuine one?

Since the medal 50 is removed to the outside by the selector 30, it cannot be determined whether the medal 50 has passed in the normal direction.

Then, 50 regular medals are inserted, and the medal 5
0 reaches the medal path 40, the presence of the medal 50 is first confirmed by the first switch 10.

That is, in this way, the presence of the medal 50 causes the first switch l.
If detected by O, the first switch lO changes from the state of 0 to the state of 1.

Conversely, unless the first switch IO changes from the 0 state to the 1 state, it is determined that the medal 50 has not been inserted.

Further, the medal 50 is inserted and the first switch 10 is set to 1. That is, when it is detected that the second switch 20 is in the ON state, it is then detected whether the second switch 20 is in the 0 state, that is, in the OFF state.

Here, if the second switch 20 is not 0, that is, if it is already in the ON state, it will be in the state (I) or (F) in Fig. 2, so this is detected as an error. be.

In addition, after it is detected that the second switch 20 is 0, the first switch IO becomes 0, that is, it is detected whether the first switch 20 is in the OFF state or not. . Here, if the first switch lO is not set to 0, the medal 50 is still at the f51 switch lO.
It refers to a state in which one cannot completely separate from oneself.

When the medal 50 is completely separated from the first switch IO, the second switch 20 is then set to 1, that is, ON.
It is determined whether the state is the same or not. Here, first
In a case where the switch 10 is set to 1, the second switch 20 is then set to 0, and the second switch 20 is also set to 0 even though the first switch 10 is set to O, for example, as shown in FIG. ) or (E), etc., it shall be displayed as anything.

If the second switch 20 is set to 1, it is assumed that the medals 50 have been inserted in the correct order as shown in FIG. 2 (A), and no fraud has been committed. It will be output as a.

Therefore, at the moment when it is detected that the second switch 20 is set to 1, it is possible to count by 1, assuming that the genuine medal 50 has been correctly inserted. After that, it is also possible to add one to the count by detecting that the second switch 20 is turned off.

If such a determination result is determined according to the flowchart shown in FIG. 3, the result will be (B) in FIG.

(D), (E), and (F) will all be output as errors.

Also, at this time, regarding FIG. 2(A), it will be counted as having been correctly inserted.

In addition, regarding FIG. 2(C), the first switch 10
In the flowchart shown in FIG. 3, it is determined that the first switch IO is not 1, so that the -off count does not move.

Therefore, in the present invention, although items that are input in the normal order are counted, items that are placed in a different order, that is, items that have been fraudulently committed in some way, are not only not counted, but also Since errors are displayed for most cases, such fraud can be prevented.

In the illustrated example, the first switch 10 and the second switch 20 are shown adjacent to each other, but they can also be provided apart as long as the distance is shorter than the diameter of the inserted medal 50.
It is.

Furthermore, although the medal 50 has been described as an example of the object to be detected, other objects can also be used.

[Effects of the Invention] As explained above, the present invention takes into consideration the complexity of mechanically detecting unauthorized input or the high number of failures, etc.
There are two switches on the device itself.

By detecting that these two switches are turned on in sequence, if the same coin or medal is moved up and down repeatedly, it will be detected as an error. This prevents the judgment from being made as if a plurality of sheets had been inserted.
