DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin checking mechanism which is installed in a coin receiving device such as a coin locker, a vending machine, and a leisure casing, and which accepts only coins having a regular diameter.

[0002]

2. Description of the Related Art A front view of FIG. 6 shows an example of a coin receiving apparatus. A coin insertion slot 2, a coin return port 3, a customer lock 4, a customer lock 4, and a manager are provided on a front wall 1 of the coin receiving apparatus. A management lock 5 and the like to be used are provided. When a customer inserts a predetermined coin into the coin slot 2, a coin checking mechanism provided at the back of the coin slot 2 inspects the coin diameter, weight, pattern, etc., and detects that a regular coin has been inserted. Then, the key 6 of the customer lock 4 can be operated, and when the key 6 is operated, the locking rod 7 protrudes (or sinks) to lock (or unlock) the door (not shown) of the article storage. Therefore, the user can use the goods storage of the coin receiving device or purchase the goods of the vending machine.

As a general check mechanism for checking the diameter of a coin, a check mechanism of a type combining two levers as shown in FIG. 7 has been known for a long time. See, for example, JP-A-2-133788.
In this check mechanism, a substrate 8 having a coin receiving port 9 on the front surface and an upright wall 10 on the rear side is provided on the back side of the coin insertion slot 2, and support shafts 11 and 12 are erected on the substrate 8. . One end of the diameter sensing lever 13 on the support shaft 11 (the left end in FIG. 7)
The bent portion 14 a of the V-shaped coin passage allowing lever 14 is pivotally attached to the support shaft 12.

[0004] One end of the diameter sensing lever 13 has a cam surface 13 projecting slightly below the upper end surface of the coin receiving slot 9.
a on the other end (the left end in FIG. 7).
3b is provided, and the diameter sensing lever 13 is urged clockwise by its own weight. Due to its own weight, the upper pushable arm 14b rests on the pushing piece 13b, and the lower retreat arm 14c of the coin passage permitting lever 14 projects into a coin passage formed behind the coin receiving slot 9. .

When the coin C is inserted into the coin insertion slot 2, the lower surface of the coin C contacts the lower end surface of the coin receiving slot 9 to position the height of the coin C. As a result, the diameter sensing lever 13 rotates counterclockwise about the support shaft 11, and the pushing piece 13b pushes the pushed arm 14a upward. The pushed-in coin passing permission lever 14 rotates clockwise around the support shaft 12, and the retreat arm 14b retreats above the coin path, so that the coin C can pass.

When the diameter of the coin C is smaller than that of a regular coin, the amount of rotation of the diameter sensing lever 13 is reduced, so that the amount of retreat of the retreat arm 14c is reduced, and the retreat arm remaining in the coin passage is reduced. 14c prevents coin C from passing. When the diameter of the coin C is larger than that of a regular coin, the coin C tries to rotate the diameter sensing lever 13 to a large extent. The rotation of the sensing lever 13 does not occur.
Therefore, the coin C cannot pass between the cam surface 13a and the lower surface of the coin receiving slot 9. In this way,
Only coins C of a regular diameter are accepted.

[0007]

The money accepting device has various uses, and depending on the purpose of use, 10 yen, 50 yen,
Any one of the coins of 100 yen and 500 yen is used, and some coins may be used. Therefore,
In a money receiving apparatus manufacturing factory, a check mechanism must be prepared according to the type of each coin and medal, so that management such as production, stock, and transportation is complicated, and waste of holding many stocks occurs.

[0008] Further, if it is desired to change the coins used by the installed money receiving device from, for example, 100 yen to 500 yen for convenience, it is necessary to replace the coins with a check mechanism suitable for the coins. An object of the present invention is to provide a money accepting device that can be used for any coin with a simple adjustment by solving the above problem.

[0009]

Means for Solving the Problems] To achieve the above object, the present invention is, behind the coin slot of the coin receiving device, it is disposed a substrate to be a guide wall of the coin, carp substrate
The middle portion of the diameter sensing lever and the bent portion of the V-shaped coin passage allowing lever are pivotally connected to the side of the passage, and one end of the diameter sensing lever is close to the upper end surface of the coin insertion slot and from the upper end surface. A cam surface protruding slightly downward, a pushing piece provided at the other end, and a pushed arm which is pushed upward by the pushing piece on the coin passing permitting lever; In a coin checking mechanism provided with a retreat arm which retreats from a coin passage communicating with the coin insertion slot when the arm is pushed, the substrate is provided so as to be tiltable, and the upper front end of the substrate is provided with the coin insertion slot. urges the abutting direction front wall is provided, at one end of the selection lever from the coin passage side of the substrate which is pivotally mounted a <br/> intermediate portion on the opposite side, the coin path side
A coin receiving slot is provided between the positioning pin and the upper end face of the coin insertion slot, and an adjusting screw is provided at the other end of the selection lever to provide a coin receiving slot. A screw hole in which the adjustment screw can be screwed when the selection lever is tilted so that various coins can pass through the gap between the entrances is provided in the substrate.

It is desirable to provide a gate spring for urging the diameter sensing lever to push the pressing piece downward, and to make the urging force of the gate spring slightly larger than the urging force of the substrate.

Alternatively, the coin check mechanism of the present invention may be configured as follows. A substrate serving as a coin guide wall is provided behind the coin insertion slot of the coin receiving device, and an intermediate portion of a diameter sensing lever and a bent portion of a V-shaped coin passage permitting lever are pivotally attached to the substrate. At one end of the diameter sensing lever,
A cam surface is formed near the upper end surface of the coin insertion slot and protrudes slightly downward from the upper end surface, and a pushing piece is provided at the other end. and the pushing arm is pushed in, when the該被pushing arm is pushed, the coin coin detecting mechanism provided with a retraction arm to retract from the coin passage communicating with the coin slot, the upper Symbol substrate Is provided at the front end of a selection lever having an intermediate portion pivotally attached to the substrate, and a positioning pin for abutting against the lower surface of the coin is provided at a front end of the selection lever, and a coin receiving slot is provided between the positioning pin and an upper end surface of the coin insertion slot. configure screwed an adjusting screw into the screw hole provided at the other end of the selection lever, when the distance between the upper Symbol coin slot tilts the selection lever as various coins is passable dimensions Screw holes into which the adjustment screws can be screwed Provided, providing a substrate spring for biasing said substrate in a direction in which the positioning pin is increased.

[0012]

When the adjustment screw screwed into the screw hole of the selection lever is selected and screwed into the screw hole of the board , the inclination of the selection lever is adjusted, and the position of the positioning pin is adjusted to a position suitable for the coin to be used. Become. Therefore, one check mechanism can be used for checking various coins.

Since the lower surface of the coin inserted into the coin insertion slot hits the positioning pin, the insertion height of the coin is determined at the correct position, and the upper surface of the coin pushes the cam surface of the diameter detecting lever to rotate the diameter detecting lever. Since the pushing piece of the lever pushes the driven arm of the coin passing allowing lever, the coin passing allowing lever rotates. Therefore, when a legitimate coin is inserted, the coin passing permission lever rotates to a position where the retreat arm retreats from the coin path, and the coin is accepted.

When a coin smaller in diameter than a regular coin is inserted, the amount of rotation of the diameter sensing lever is reduced, so that the amount of rotation of the coin passage permitting lever is also reduced, and the retreat arm remains in the coin path, thereby preventing the coin from entering. Even if you insert the coin so that the upper surface of the coin is pressed firmly against the cam surface without touching the lower surface of the small-diameter coin to the positioning pin, and the amount of rotation of the diameter sensing lever is the same as for a regular coin, you can pass the coin. Since the diameter sensing lever is biased in the direction opposite to the pressing force, it is possible to prevent the amount of rotation of the diameter sensing lever from being increased, thereby preventing the coin from passing.

If the urging force of the diameter detecting lever is slightly greater than the urging force of the substrate due to its own weight, the diameter detecting lever does not rotate unless a large force for lifting up to the substrate is generated. Increase.

Although the position of the positioning pin protrudes above the lower end face of the coin slot, when the substrate is urged in a direction to increase the amount of projection, the lower surface of the coin inserted into the coin slot is always positioned. Since the small diameter coin is pressed against the cam surface by contact with the pin, the rotation amount of the diameter detecting lever is prevented from being increased. Coins larger in diameter than regular coins cannot pass between the positioning pin and the cam surface, and are therefore prevented from passing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described. FIG. 1 is a front view of a check mechanism of the first embodiment as viewed from the inside of a coin receiving device, and FIG. 2 is a plan view of FIG. is there. As shown in FIG. 2, a coin insertion slot 16 is formed in the cover 15 of the coin receiving device, and the cover 15 is fixed to the front surface of the front wall 18 of the machine casing 17. The front wall 18 has a coin insertion slot 19 overlapping the coin insertion slot 16 on the cover 15, and a side wall 20 serving as one guide wall of the coin passage is bent and extended at an end of the front wall 18.

The support member 21 disposed at an interval with respect to the side wall 20 has a leg portion 21 a which is screwed to an inner wall surface of the side wall 20, and is provided between the side wall 20 and the support member 21. A substrate 23 serving as the other guide wall of the coin passage is inserted, and a support shaft 25 penetrating the side wall 20 is inserted into a hole 24 provided in the substrate 23. As shown in FIG.
Is located on the right side of the position of the center of gravity of the substrate 23,
The substrate 23 is biased counterclockwise by its own weight with the support shaft 25 as a fulcrum. An upright wall 23a is provided at the left end of the substrate 23 so as to substantially contact the front wall 18.

A pin 26 and an arc-shaped hole 27 are provided near the upright wall 23a, an upright wall 23b is provided at the right end of the substrate 23, and a coin passage formed between the upright walls 23a, 23b is A diameter sensing lever 28 and a coin passing permission lever 29 described below are accommodated. Diameter sensing lever 28
Is pivotally mounted on a pin 26 provided on a substrate 23, a cam surface 30 is formed on the lower surface of one end (the left end in FIG. 1), and a pushing piece 31 is extended on the other end.

Gate spring 3 wound around pin 26
2 of one end 32a is engaged with the substrate 23, the pressing piece 31 of the other end 3 2 b is through the arcuate hole 27 diameter sensing lever 28
Is locked. Accordingly, the diameter sensing lever 28 is
Is urged clockwise with the fulcrum as the fulcrum.
Is in contact with the upright wall 23a.

At this time, the cam surface 30 is in the coin slot 1
6 and 19 project slightly below the upper end surfaces. The reason for urging the diameter sensing lever 28 clockwise is that the cam surface 30
Makes the diameter sensing lever 28 rotate counterclockwise when pressed by a coin, and prevents a coin smaller in diameter than a regular coin from pressing the cam surface 30 and passing through the check mechanism. That's why. If the biasing force of the diameter sensing lever 28 in the clockwise direction is greater than the biasing force of the substrate 23 due to its own weight, the prevention effect is enhanced as will be described later in the section of operation.

The coin passing lever 29 has a bent portion 29
By the pushed arm 33 and the retreating arm 34 protruding from the position a, a substantially V-shape is formed, and the bent portion 29 a is pivotally attached to the support shaft 25. The retreat arm 34 protrudes into the coin passage passing through the coin insertion slots 16 and 19, but when the pushed arm 33 is pushed by the pushing piece 31 and rotates counterclockwise by a predetermined amount, The retreat arm 34 retreats above the coin path.

Below the substrate 23, a shaft 35 projecting from the opposite surface of the coin passage is fixedly mounted.
6 is pivoted. One end of the selection lever 36 (FIG. 1)
, A positioning pin 37 projecting into the coin passage is provided. The positioning pin 37 regulates the coin insertion height when the lower surface of the coin C inserted into the coin insertion slots 16 and 19 contacts,
The position of the positioning pin 37 must be changed according to the type of the coin C.

In order to change the position of the positioning pin 37,
Three screw holes 38, 39, 40 are provided at one end of the selection lever 36.
Are provided in the three screw holes 38, 39, and 40.
The adjustment screws 41 are selectively screwed together (in FIG.
9 shows a state in which the adjusting screw 41 is screwed into the central screw hole 39), and the tip of the adjusting screw 41 is connected to any of the five engaging holes 42, 43, 44, 45, and 46 provided in the substrate 23. Insert crab. FIG. 3 is an explanatory view of the position of each of the engagement holes 42 to 46. The engagement hole 42 is for a 50-yen coin, and the engagement hole 43 is one.
For 0 yen coin, engaging hole 44 is for 100 coin, engaging hole 4
5 is for a 500 yen coin, and the engagement hole 46 is for a medal (see FIG. 3).

Next, the operation of the money checking mechanism of the first embodiment configured as described above will be described. In order to set the check mechanism for a 50-yen coin, an adjustment screw 41 screwed into the screw hole 38 of the selection lever 36 is inserted into an engagement hole 42 for a 50-yen coin, and the inclination of the selection lever 36 is adjusted. In this case, the position of the positioning pin 37 is a position suitable for a 50 yen coin. In order to use the check mechanism for 10-yen coins, the adjustment screw 41 screwed into the screw hole 38 of the selection lever 36 may be screwed into the engagement hole 43 for 10-yen coins.

In order to use the checkout mechanism for 100 yen coins,
The adjustment screw 41 screwed into the screw hole 39 of the selection lever 36 is screwed into the engagement hole 44 for a 100-yen coin, and the selection lever 3
In order to adjust the inclination of 6 and use the check mechanism for 500 yen coins, the adjustment screw 41 screwed into the screw hole 39 of the selection lever 36 is screwed into the engagement hole 45 for 500 yen coins. To use the check mechanism for medals, the screw hole 4
The adjustment screw 41 screwed to 0 may be screwed into the medal engagement hole 46. With the simple operation described above, one check mechanism can be used for checking various coins.

As described above, when the position of the positioning pin 37 is adjusted according to the type of coin, the distance between the positioning pin 37 and the cam surface 30 becomes a dimension for receiving a regular coin. The coin C inserted into the coin insertion slots 16 and 19 becomes the correct insertion position by the positioning pin 37, and the coin C is inserted.
Pushes the cam surface 30, so that the diameter sensing lever 2
8 rotates by a predetermined amount, the pushing piece 31 pushes the driven arm 33 of the coin passing allowing lever 29, and the coin passing allowing lever 29 rotates by a predetermined amount. Therefore, when the regular coin C is inserted, the retreat arm 34 retreats above the coin path, and the coin C is accepted.

When a coin C smaller in diameter than a regular coin is inserted, the amount of rotation of the diameter sensing lever 28 is reduced, so that the amount of rotation of the coin passing permission lever 29 is also reduced, and the retreat arm 34 remains in the coin path, and Prevent entry. Without hitting the small-diameter coin C on the positioning pin 37, the cam surface 30
If you insert it so that it is strongly pressed against the
Since the amount of rotation of the coin 8 is the same as that of a regular coin, there is a danger that a small-diameter coin C will pass through, but since the diameter sensing lever 28 is urged by the gate spring 32 in the direction opposite to the pressing force. In addition, it is possible to prevent the amount of rotation of the diameter sensing lever 28 from being increased, thereby preventing the coin C having a small diameter from passing therethrough.

The urging force of the gate spring 32 is applied to the substrate 2
If the pressing force of the small-diameter coin C is applied to the cam surface 30 of the diameter detecting lever 28 by slightly increasing the urging force of the substrate 23 due to its own weight of 3, the substrate 23 rotates clockwise and the diameter detecting lever 28 moves away. Because it is not rotated,
The effect of preventing the passage of the small-diameter coin C is enhanced.

FIG. 4 is a front view of the check mechanism of the second embodiment viewed from the inside of the coin receiving device, and FIG. 5 is a plan view thereof. The second embodiment is provided with a board spring 47 for urging the board 23 in the direction in which the positioning pins 37 are raised. Other than the above, the second embodiment is the same as the first embodiment. Therefore, only the board spring 47 will be described. .

The substrate spring 47 wound around the support shaft 25
The end 4 7a is engaged with the support member 21, the other end 4 7b is locked in the right upper surface of the substrate 23. Accordingly, the substrate 23 is urged clockwise with the support shaft 25 as a fulcrum, and the positioning pins 37 project largely upward from the lower surfaces of the coin insertion slots 16 and 19.

When a regular coin C is inserted into the check mechanism of the second embodiment constructed as described above, the coin C
Are inserted by pushing the positioning pin 37 downward, but the operations of the diameter sensing lever 28 and the coin passing allowing lever 29 are the same as those in the first embodiment. When a small-diameter coin C is inserted, the small-diameter coin C always hits the positioning pin 37, and the small-diameter coin C pushes the positioning pin 37 downward. Coin C
Rotates counterclockwise to an angle that passes through the positioning pin 37, but only the cam surface 30 is prevented from being pushed and the retreat arm 34 remains in the coin passage, so that the passage of the small-diameter coin C is prevented. . The large coin C cannot pass through
This is the same as the embodiment.

[0033]

Since the present invention is configured as described above, it has the following effects. (1) Since the check mechanism can be adjusted so as to be suitable for various coins, one check mechanism can be used also as a check mechanism for various coins. Accordingly, in the production facility of the check mechanism, the troublesome management of manufacturing and preparing various check mechanisms and the waste of stocking various check mechanisms have been eliminated. (2) There is no danger of accepting coins smaller in diameter than regular coins, and the reliability of the check mechanism has been improved.
