The present applicant has previously proposed a coin that can be used for both 100 yen and 500 yen coins in Utility Application No. 197942, by improving the 100 yen coin.

Therefore, first of all, this Utility Application No. 197942-1988 will be explained.

In FIG. 9, 1 is a machine frame, on both sides of which a ball passage 2 and a coin passage 3 are formed.
Coin passage 3 is a shared passage for 100 yen coins and 500 yen coins.

Reference numeral 10 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 clockwise in the figure. A locking portion 13 having two locking step portions 11 and 12 is integrally formed on the star foil 10. In addition, the star wheel 10 has a gear 1.
4 is integrally formed, and this gear 14 is
Since the cam gear 30 meshes with the cam gear 30 via the intermediate gear 20, the cam gear 30 is engaged with the star wheel 10.
It is designed to rotate clockwise in accordance with the rotation of .

As shown in FIG. 10, a cam body 40 is integrally provided on the front surface of the cam gear 30, and an intermittent gear 33 having first teeth 31 and second teeth 32 and a protrusion 34 are provided on the back surface. It is integrated. Therefore, the cam body 40, the intermittent gear 33 and the protrusion 34
rotates together with gear 30.

The cam body 40 has first, second, and third step portions 41 and 4.
2, 43, and first, second, and third cam surfaces 40a, 40b, 40, respectively, between these step portions.
c is formed. Further, the third step portion 43 and the first
There is a corner 44 between the steps 41, and this corner 4
4 and the first step 41, the fourth cam surface 40
d is formed. The fourth cam surface 40d has a large diameter, and the first, second, and third cam surfaces have smaller diameters in this order.

50 is a coin receiving lever, and this coin receiving lever 50 is formed with an opening 53 into which the cam body 40 is inserted. Two opposing protrusions 51 and 52 protruding toward the cam body 40 are formed in the opening 53 .

Further, the coin receiving lever 50 is formed with a coin receiving portion 57 that projects into the coin passage 3,
Furthermore, a first pin 54 and a second pin 55 are formed on the back surface.

Although the coin receiving lever 50 is rotatable about the pivot 56, the extent of its rotation is restricted by the projections 51, 52 coming into contact with the cam body 40.

Therefore, the rotation width of the coin receiving portion 57 protruding into the coin passage 3 is also restricted.

The wall surface 3a of the coin passage 3 corresponding to the coin receiving portion 57 has a first recess 3b and a second recess 3c.
are formed, and these recesses 3b and 3c serve as a detour for the coin. Further, a protrusion 3d for locking a coin is formed between the recesses 3b and 3c.

Reference numeral 60 is a link connected to the coin receiving lever 50, and a locking pawl 61 that engages with and disengages from the locking stepped portion 11 or 12 of the locking portion 13 of the star foil 10 is formed on the upper part of the link.

The link 60 is connected by a shaft 58 provided on the coin receiving lever 50, and when the coin receiving lever 50 receives a coin and swings counterclockwise in FIG. It is adapted to be detached from the locking step 11 of the star foil.

Note that the shaft 58 serves as a weight that biases the coin receiving lever 50 clockwise. 4 is a guide piece of the link 60 formed integrally with the machine frame 1.

This ascending and descending link 60 and star wheel 10
As shown in FIG. 27, the relationship between the
2,173 The locking claw 17 is attached to the rotating lever 170.
1 may be provided, and the locking pawl 171 may be locked to the locking step portions 11 and 12 of the locking portion 13 integrally formed on the star wheel 10. In this case, guide 4 of link 60 is unnecessary, but
Since the locking pawl 171 rotates around the pivot portion 173, the locking with respect to the locking steps 11 and 12 becomes reliable.

Next, a holding mechanism for holding the star foil 10 in the released state until the pachinko balls equivalent to the inserted coins flow down will be explained.

The 100 yen holding mechanism consists of a protrusion 51 of a coin receiving lever 50 and a cam body 40, and the coin receiving lever 50 receives a 100 yen coin in its coin receiving portion 57 and swings counterclockwise. The star wheel 10 is released, the cam gear 30 rotates, the 100 yen coin is released, and the coin receiving lever 50 is released.
When the gear rotates clockwise and attempts to return to its original position, the return is restricted by the contact between the protrusion 51 and the cam body 40, and the cam gear 30 rotates once, causing the protrusion 5 to return to its original position.
The link 60 is maintained in a released state with respect to the star foil 10 until the link 60 contacts the third cam surface 40c of the cam body 40 again.

The 500 yen holding mechanism includes an intermittent gear 33 formed on the back side of the cam gear 30, a count body 70 loosely fitted coaxially with the intermittent gear 33, and a coin receiving lever 50 coaxially supported in the inner part of the intermittent gear 33. retention link 80
Consisting of

As shown in FIG. 11, the count body 70 has a gear 71 having 20 teeth integrally formed on its front surface, and an annular guide 72 integrally formed on the outer periphery of its back surface. The annular guide 72 has an opening 73;
The end of the annular guide 72 facing this opening 73 is
It forms a slope 74 that widens inward.

The count body 70 is set so that its opening 73 is on the right side before rotation, and a pin 8 of a holding link 80, which will be described later, is inserted into this opening 73.
2 (Fig. 12) can enter.
Further, a leaf spring 75 is provided that contacts the gear 71 to prevent the set position from shifting due to vibrations of the machine body (FIG. 9).

As shown in FIG. 12, the holding link 80 includes a groove 81 that engages with the second pin 55 of the coin receiving lever 50, a pin 82 that engages with and disengages from the opening 73 of the annular guide 72 of the counter body 70, and It has a small gear 83 that meshes with the gear 71 of the count body and the intermittent gear 33 of the cam gear 30, and a leaf spring 84 that comes into contact with the small gear 83.

The small gear 83 has four teeth at the top, which mesh with the intermittent gear 33 of the cam gear 30.
The lower part has 8 teeth, which mesh with the gear 71 of the count body 70 (the first
(See Figure 5).

Therefore, in the 500 yen holding mechanism, when the coin receiver lever 50 receives a 500 yen coin and rotates more than when receiving a 100 yen coin, the holding link 80 also rotates due to the engagement between the second pin 55 and the groove 81. , as shown in FIG.
3, the small gear 83 is rotated by the drive of the intermittent gear 33 of the rotating cam gear 30, which causes the count body 70 to rotate clockwise as shown in FIG. The pin 82 is displaced, and the pin 82 relatively enters the count body 70 along the annular guide 72. Therefore, even if the coin receiving lever 50 attempts to release the 500 yen coin and return to its original position, the pin 82 of the holding link 80 will come into contact with the inner surface of the annular guide 72 of the counter body 70, and the groove 81 of the holding link will not fit into the coin receiving position. Since it is engaged with the second pin 55 of the lever 50, the return of the coin receiver lever 50 is restricted, and due to the number of teeth, the cam gear 30 rotates five times, and the pinion 83 rotates.
The open state of the link 60 with respect to the star foil 10 is maintained until the counting body 70 rotates 2.5 times, the opening 73 returns to its original position, and the pin 82 escapes from the counting body 70. .

The above is the ball lending mechanism, which is the basic structure of this ball lending machine, which also includes a coin cutting mechanism, a fraud prevention mechanism, and a pulse generation mechanism.

First, let me explain about the coin cutting mechanism.
The coin cutter mechanism removes coins one by one from the coin receiver lever 5 when two or more coins are continuously inserted.
The coin cutter lever 100, the coin stopper 120, and the first pin 54 protruding from the back surface of the coin cutter lever 50 are engaged with and disengaged from each other to allow the coin to fall onto the coin receiver 57 of the coin cutter 50. It is made up of a regulation plate 110 that regulates rotation of 100 units.

The coin cutter lever 100 is rotatably attached to the side of the coin passageway 3 by a pivot shaft 101.

The coin cutter lever 100 has a protruding part 102 that protrudes into the coin passage and a pivot 1 from this protruding part 102 above the point in the coin passage 3 where the coin receiving part 57 of the coin receiving lever 50 protrudes.
01 is provided with a pin 104 which is an engaging portion. The pin 104 is provided to protrude from an upwardly extending portion 103 of the protrusion 102 . In addition, the extension section 103
A weight 105 is provided at the tip of the protrusion 102.
A pin 106 is provided to protrude from the end extending further downward.

The regulation plate 110 is pivotally supported by a shaft 111,
A slit 112 is formed to engage with the pin 106 of the coin cutter lever, and the coin cutter lever 100 is interlocked with this engagement.

This regulation plate 110 includes a lateral periphery 113 that comes into contact with the pin 54 of the coin receiving lever 50 to restrict the swinging of the coin receiving lever 50 when the lever is not swinging, and a peripheral edge 113 in the horizontal direction that restricts the swinging of the coin receiving lever 50 when the coin receiving lever 50 is not swinging. pin 5
It has a longitudinal periphery 114 that abuts 4.

In addition, as shown in FIG. 9, a coin receiving lever 50
rotates clockwise, the protrusion 51 comes into contact with the third cam surface 40c of the cam body 40, and the locking pawl 61 of the link 60 locks with the locking stepped portion 11 of the locking portion 13 of the star wheel 10. When the coin receiver lever 50
A stopper 110a is provided to protrude from the pivot portion of the shaft 111 with respect to the regulation plate 110 so as to contact the bottom surface of the shaft 110 at a substantially right angle.

Note that the coin cutter lever 100 is caused by its own weight and the weight of the regulation plate 110 to cause the protrusion 102 to close.
is biased in the direction of protruding into the coin passage 3.

The coin stopper 120 is pivotally supported on a shaft 121, and has an approximately fan-shaped upper edge 122 having an arc shape centered on the shaft 121, and a coin stopper 120 having an arcuate upper edge 122 centered on the shaft 121.
A doglegged slit 123 is formed as a locking portion that engages with the pin 104 of 00.

Due to the engagement between the pin 104 and the slit 123, the coin stopper 120 is interlocked with the coin cutter lever 100, and when the coin cutter lever 100 swings, the shaft 121 is moved from the slit 123 of the coin stopper.
The tip portion 124 located far away from the coin passage 3 is designed to quickly protrude into the coin passage 3. In addition, 107
is an arcuate slit centered on a shaft 101 formed on the coin cutting lever 100.

Next, the fraud prevention mechanism is for preventing predetermined fraud, and includes a fraud prevention lever 130.
It consists of a coin detection lever 140, a protrusion 34 on the back surface of the cam gear 30, a corner portion 44 of the cam body, a first protrusion 54 on the back surface of the coin receiving lever 50, and a protrusion 52 on the opening.

The anti-tampering lever 130 is generally L-shaped as a whole, consisting of a horizontal portion 131 and a vertical portion 132, and is rotatably mounted on the aforementioned pivot shaft 121. The tip 133 of the horizontal portion 131 is located in the rotation orbit of the protrusion 34 on the back surface of the cam gear 30, and the vertical portion 132 has a recess 134 that engages with and disengages from the pin 54 of the coin receiving lever 50. is formed, and further below this recess 134 is a hook 13.
5 is formed. The detection lever 140 is the pivot 1
41 and is rotatably attached.

The detection lever 140 has a tip portion 1 that can protrude below the point in the coin passage 3 where the coin receiving portion 57 of the coin receiving lever 50 projects.
42, and the fraud prevention lever 1
This hook portion 1 is located at a location opposite to the hook portion 135 of 30.
two protrusions 143 that can come into contact with and be detached from 35;
It has 144.

Note that the levers 130 and 140 are biased clockwise by the action of weights 136 and 145 attached to them, respectively.

Next, the pulse generating mechanism is required to calculate the rental amount of pachinko balls by the ball lending machine, and is for generating a pulse signal corresponding to the inserted coin.

The 100 yen coin consists of the fraud prevention lever 130, the coin detection lever 140, and the micro switch 146 that detects the rotation of the detection lever, and the 500 yen coin also includes the 500 yen coin.
It consists of four pawls 75, 76, 77, 78 formed on the count body 70 constituting the circle holding mechanism and a pulse generating lever 150 that engages and disengages from the pawls. The angles formed by claws 75 and 76, 76 and 77, and 77 and 78 are
The angle between the claws 78 and 75 is 144 degrees.

The micro switch 146 has a detection needle (not shown), which detects this and generates one pulse each time the detection lever 140 swings once.

Further, as shown in FIG. 16, the pulse generating lever 150 is pivotally supported on a shaft 151, and its lower end 152 is in the rotating orbit of the pawl 75 of the counter body 70, and its upper end 153 is a tamper-proofing lever. lever 130
It is in contact with the upper edge of the horizontal portion 131 of.

Therefore, when the count body 70 rotates, the pulse generation lever 150 engages and disengages with the pawl 75 and the like, and contacts the horizontal portion 131 of the fraud prevention lever 130, so that the pulse generation lever 150 activates the coin detection lever via the fraud prevention lever 130. 140 is swung four times. Note that 154 is a weight provided at the upper end 153.

In addition, 160 is a regulating member for ensuring the engagement between the star foil and the pachinko ball, 161
is a tank for temporarily storing the pachinko balls that are released.

The configuration of the conventional example has been described above, and the operation will now be described.

The basic operation of this ball lending machine is to swing the coin receiver lever 50 with the inserted coin, actuate the link 60, and disengage the locking pawl 61 from the locking part 13 of the star wheel. Although the purpose is to rent out a predetermined number of pachinko balls, the coin cutter mechanism is to feed coins that are continuously inserted into the coin receiving lever 50 one by one. The operation of the system and the fraud prevention mechanism will be explained step by step below.

Before a coin is inserted, as shown in FIG.
is in contact with the third cam surface 40c [Fig. 10a]. The link 60 also has its own weight and the coin receiving lever 5
0, and its locking pawl 61
is engaged with the locking step 11 of the star foil 10.

Further, a stopper 110a protruding from the regulation plate 110 is in contact with the lower surface of the coin receiving lever 50 at a substantially right angle.

Therefore, the star wheel 10 is in a non-rotatable state, and the pachinko balls (not shown) do not flow down.

In this state, the protrusion 102 of the coin cutter lever 100 of the coin cutter mechanism protrudes into the coin passage 3, and the pin 54 comes into contact with the horizontal edge 113 of the regulation plate 110, so that the swinging of the coin receiving lever 50 is also regulated. There is.

The tip 124 of the coin stopper 120 does not protrude into the coin passage 3. Also, fraud prevention lever 1
30, the vertical part 132 is in contact with the wall 3f forming the coin passage 3, and the tip 133 of the horizontal part 131 is in contact with the wall 3f forming the coin passage 3.
is inserted into the back side of the cam gear 30. The upper edge of the protrusion 143 of the detection lever 140 comes into contact with the lower edge of the hook 135 of the anti-tamper lever 130, making it impossible to rotate clockwise, and the tip 142 protrudes into the coin passage 3. Not yet.

The retaining link 80 is located on the back side of the cam gear 30, and its groove 81 engages with the second protrusion 55 of the coin receiving lever 50, and the pin 82 engages with the second protrusion 55 of the coin receiving lever 50.
Therefore, the small gear 83 does not mesh with the gear 71 of the count body.

The count body 70 is located on the back side of the cam gear 30, and its opening 73 (see FIG. 11) is in the rotational path of the pin 82 of the retaining link 80.
It is in a position to accept 2.

The pulse generating lever 150 is located on the back side of the cam gear 30, and is urged counterclockwise by a weight 154 (FIG. 16);
The rotation thereof is restricted by coming into contact with the anti-tampering lever 130, and the lower end 152 is in the rotation orbit of the pawl 75 and the like of the count body 70.

First, we will explain the case where there is no wrongdoing.

() When a 100 yen coin is inserted.

(i) When the 100 yen coin a is inserted, the 100 yen coin a passes through the tip 124 of the coin stopper 120 and hits the protrusion 102 of the coin cutter lever 100, and as shown in FIG.
0 is rotated counterclockwise, and the regulation plate 110 is rotated clockwise in accordance with this, so that the stopper 110 of the regulation plate 110 is rotated.
a rotates clockwise, and the lateral peripheral edge 113 of the coin receiving lever 50 with respect to the first pin 54
regulations will be lifted. As a result, the coin receiving lever 50 becomes rotatable, and the coin receiving lever 50 becomes rotatable.
The yen coin a hits the coin receiving part 57 and pushes it down.

Further, at the time when the coin cutter lever 100 swings counterclockwise, the tip 124 of the coin stopper 120 that is interlocked with the coin cutter lever 100 immediately protrudes into the coin passage 3, and when coins are continuously inserted, the next Coin a′ is 100 yen,
Regardless of 500 yen, this tip 1
24 to prevent it from falling.

At this time, the coin cutter lever 100 is biased clockwise by its own weight and the weight of the regulation plate 110 as described above, but the vertical edge 114 of the regulation plate 110 causes the coin receiving lever 50 to swing. The stopper 1 of the regulation plate 110 contacts the first pin 54 of the regulation plate 110.
Since the coin receiving lever 10a is in contact with the lower surface of the coin receiving lever 50, its rotation is restricted, and therefore the coin cutting lever 100 also does not swing and its pin 104
Due to the engagement between the stopper 120 and the dogleg groove 123 of the stopper 120, the stopper 120 also does not rotate clockwise, and its tip 124 securely locks the next coin a'.

Note that the horizontal peripheral edge 113 of the regulation plate 110 has an arc shape centered on the axis 111, and the vertical peripheral edge 114
is formed in an arc shape centered on the shaft 56 of the coin receiving lever 50, so the above operation is performed smoothly. On the other hand, this means that the first pin 54 may be damaged by an impact or the like on the regulating plate 11.
This creates a risk that the periphery of 0 may be moved inadvertently.

When the 100 yen coin a pushes down the coin receiving portion 57 of the coin receiving lever 50, the coin receiving lever 50 rotates counterclockwise, and the opening 5 of the coin receiving lever 50 rotates counterclockwise.
The protrusion 52 of No. 3 is the first cam surface 40a of the cam body 40.
The swinging is regulated by contacting the
The 100 yen coin a is supported by the coin receiving portion 57 of the coin receiving lever and the corner portion 3d of the coin passage 3 and comes to a stop.

Then, as the coin receiver lever 50 swings counterclockwise, the link 60 rises, and the engagement between the locking pawl 61 and the locking portion 11 of the star foil is released, and the star wheel 10 becomes rotatable. The pachinko balls become engaged with the star foil 10 and flow down the ball path 2 while being rotated. Further, in conjunction with the rotation of the star wheel 10, the cam gear 30 also starts rotating.

Note that the holding link 80 also rotates together with the coin receiving lever 50, and its pin 82 is attached to the counter body 7.
0, but does not completely enter, and since the intermittent gear 33 of the cam gear 30 and the small gear 83 of the holding link 80 are not engaged, the count body 70 also does not rotate.

(ii) As the pachinko balls flow down and the star wheel 10 rotates, the cam gear 30 also rotates clockwise, and when the protrusion 34 on the back side reaches the tip 133 of the horizontal part of the anti-tamper lever 130, It comes into contact with this and pushes up the horizontal portion 131 (see FIG. 18).

When the horizontal portion 131 is pushed up, the anti-tampering lever 130 swings counterclockwise, whereby the hook portion 135 of the anti-tamper lever 130 and the protruding portion 143 of the detection lever 140 are released from contact, and the hook portion 135 is the other protrusion 14 of the detection lever.
4 (see Figure 17) detection lever 14
0 is rotated clockwise by the weight 145,
Its tip 142 protrudes into the coin passage 3, and the recess 134 of the anti-tamper lever 130 surrounds the first pin 54 of the coin receiving lever 50 (see FIG. 18).

At this point, the coin cutter lever 100
The return to the original position is caused by the contact between the regulating plate 110 and the first pin 54 of the coin receiving lever 50, the contact between the stopper 110a of the regulating plate 110 and the coin receiving lever 50, and the contact between the regulating plate slit 112 and the coin receiving lever 50. Cutting lever pin 106
The next coin a' remains locked.

(iii) As shown in FIG. 18, when the cam gear 30 rotates further and the protrusion 34 on the back surface disengages from the tip 133 of the horizontal part 131 of the anti-tamper lever, the anti-tamper lever 130 is turned off. However, at this time, the hook portion 135 of the tamper prevention lever 130 engages with the protrusion 143 of the detection lever 140, and the return of the tamper prevention lever 130 is restricted. Note that by rotating the anti-tamper lever 130 counterclockwise,
The pulse generation lever 150 rotates clockwise,
The lower end 152 enters into the rotating orbit of the claw 75 etc. of the count body 70.
Since 0 does not rotate, these items will not engage.

(iv) As shown in FIG. 19, the cam gear 30 further rotates, and the protrusion 52 of the coin receiving lever 50 falls from the first cam surface 40a of the cam body 40 to the step 42 and comes into contact with the second cam surface 40b. When the coin comes into contact with the coin, the weight of the 100 yen coin a causes the coin receiver lever 50 to swing counterclockwise, and as a result, the 100 yen coin a, which had been supported by the coin receiver 57 and the corner portion 3d, is moved. It is released, falls through the detour 3c, presses down the tip 142 of the detection lever 140, and is then discharged out of the machine from the discharge port 3e (FIG. 9).

100 yen coin a is at the tip 1 of the detection lever 140
By pushing down 42, the detection lever 14
0 rotates counterclockwise, thereby causing the protrusion 143 of the detection lever and the hook 1 of the anti-tamper lever to
Since the engagement with 35 is released, the tamper prevention lever 1
30 rotates clockwise and returns to its original position.
As a result, the first pin 5 of the coin receiving lever 50
The concave portion 134 of the anti-tamper lever 4 is unenclosed, and the coin receiving lever 50 is in a state where it can rotate clockwise, and immediately rotates clockwise after the coin is released. Further, the detection lever 140 is
The protruding portion 143 comes into contact with the hook portion 135 of the anti-tampering lever 130, and the state is the same as the original position.
Moreover, one pulse is generated by the micro switch 146 with one swing of the detection lever 140.

As mentioned above, when the protrusion 52 of the coin receiving lever 50 falls into the stepped portion 42 of the cam body and the coin receiving lever 50 swings counterclockwise to release the coin, it is clear from FIG. The holding link 80 also rotates together with the coin receiving lever 50, and its pin 82 once enters the opening 73 of the counter body 70, but as will be described later, the coin receiving lever 50 rotates clockwise after the coin is released. Due to the rotation of the holding link 80 as the counter body rotates, it quickly escapes from the opening of the count body.

(v) Coin receiver lever 50 releasing 100 yen coin a
quickly swings clockwise due to the weight of the weight 58 and the link 60, but as shown in FIG. This means that the 100 yen holding mechanism has started.

Due to the contact, the lowering of the link 60 is also restricted, and thereby the link locking claw 61
The open state with respect to the star foil locking portion 13 will be maintained.

Thereafter, due to the rotation of the cam gear 30, the protrusion 51 of the coin receiving lever 50 is moved to the first cam surface 4 of the cam body.
0a, the link claw 61 comes into contact with the second cam surface 40b, but even in that case, the released state of the link claw 61 is still maintained.

At this point, the coin cutter lever 100
The return to the original position is caused by the contact between the regulating plate 110 and the first pin 54 of the coin receiving lever 50, the contact between the stopper 110a of the regulating plate 110 and the coin receiving lever 50, and the contact between the slit 112 of the regulating plate and the coin receiving lever 50. Cutting lever pin 106
The next coin a' remains locked.

As mentioned above, the holding link 80 also rotates clockwise along with the rotation of the coin receiver lever 50 immediately after releasing the 100 yen coin a, and the pin 82
Intermittent gear 33 of cam gear 30 and retaining link 8
Before the small gear 83 of 0 engages, the count body 70
In the case of a 100 yen coin, the intermittent gear 3
3 and the small gear 83 do not mesh with each other, and the count body 70 does not rotate.

(vi) When the cam gear 30 rotates further and has just completed one rotation, the protrusion 51 of the coin receiving lever 50 falls into the third step 43 of the cam body 40 and comes into contact with the third cam surface 40c. By rotating clockwise by that amount, the link 60 descends, and its locking pawl 61 engages with the locking portion 13 of the star foil, thereby stopping the pachinko balls from flowing down. This means that pachinko balls worth 100 yen have been lent out.

At this point, the protrusion 51 of the coin receiver lever 50 falls into the third cam surface 40c of the cam body 40 and rotates clockwise, thereby releasing the contact between the first pin 54 and the vertical peripheral edge 114 of the regulation plate 110. As a result, the regulating plate 110 and the coin cutter lever 100 swing, and the stopper 110a of the regulating plate 110 returns to its original position so as to contact the bottom surface of the coin receiving lever 50 at a substantially right angle, thereby preventing the coin receiving lever 50 from malfunctioning. prevent. When the next coin a' is present, the coin cutter lever 100 returns, the stopper 120 also returns, and the contact between the tip 124 and the coin a' is released, causing the coin a' to fall. coin
If a' is a 100 yen coin, the action explained above will be repeated with this 100 yen coin a', and if a' is a 500 yen coin, the action explained next will be performed.

() When a 500 yen coin is inserted (i) When a 500 yen coin b is inserted, the 500 yen coin b passes through the tip 124 of the stopper 120 and passes through the protrusion of the coin cutter lever 100. 102, rotate the coin cutter lever 100 as shown in FIG. 21, and further push down the coin receiver lever 50.

Also, as with the 100 yen coin, the next coin
When there is b′ (regardless of whether it is 100 yen or 500 yen),
This will be locked with the coin stopper 120. Here, since the 500 yen coin has a larger diameter than the 100 yen coin, the coin cutting lever 100 will swing more than in the case of the 100 yen coin.
Since the lower portion 123a of the doglegged groove 123 of the coin stopper 120 has an arc shape centered on the shaft 101, the stopper 120 does not swing more than necessary. This is stopper 12
This prevents the problem that the return operation becomes slow due to the zero swinging more than necessary and its tip 124 protruding too far into the coin passage 3.

That is, this is why the engaging portion of the coin stopper 120 is formed into a dogleg groove 123.
Therefore, if there are no disadvantages as described above, it is not necessarily necessary to form the engaging portion into a dogleg groove.

In addition, since the main ball lending machine uses coin passage 3 as a shared passage for 500 yen coins and 100 yen coins, the passage for 100 yen coins is wider, so the previous coin b [or the above-mentioned a] After passing the tip 124 of the coin stopper 120, the stopper tip 124 immediately protrudes so that the next coin b' [or the above-mentioned a'] can be securely stopped even if it is a 100 yen coin. However, the pin 104 of the coin cutter lever 100 should fit into the upper portion 12 of the dogleg groove 123 of the coin stopper.
3b, the tip 124 of the stopper 120 is further away from the shaft 121 than the groove 123, so the tip 124 is fast-forwarded so that even if the next coin is a 100 yen coin, it will be securely stopped. It's summery.

The star wheel 10 and the cam gear 30 start rotating due to the rotation of the coin receiver lever 50;
and the rotation of the coin receiver lever 50 is caused by the protrusion 52
The point is that the 500 yen coin is regulated by contact with the first cam surface 40a of the cam body 40 and is held between the coin receiving portion 57 and the corner portion 3d of the coin passage.
The same is true for 100 yen coins.

Further, as the cam gear 30 rotates, the protrusion 34 causes the tamper prevention lever 130 to swing,
This also causes the detection lever 140 to swing.
The same is true for 100 yen coins.

(ii) As shown in FIG. 22, the coin receiver lever 50
When the protrusion 52 falls from the first cam surface 40a of the cam body 40 to the second step 42 and comes into contact with the second cam surface 40b, in the case of a 100 yen coin, the coin receiver lever 50 rotates to release the 100 yen coin. is released,
Immediately, the coin receiver lever 50 rotated clockwise and the pin 82 of the holding lever 80, which had once entered the opening 73 of the counter body 70, also came out, but in the case of a 500 yen coin, it was smaller than a 100 yen coin. Since the diameter is large, the protrusion 52 of the coin receiving lever 50
The coin receiver lever 50 is not released by the rotation of the coin receiver lever 50 caused by the coin falling into the second stage portion 42 of the cam body 40, and remains retained between the coin receiver 57 and the corner 3d of the coin passage. Therefore, the pin 82 of the holding link 80 that has entered the opening 73 of the count body 70 also remains inserted (see FIG. 13).

(iii) In this state, while the protrusion 52 of the coin receiving lever of the cam gear 30 is in contact with the second cam surface 40b, first the first tooth 31 of the intermittent gear 33 of the cam gear 30 is held. By meshing with the small gear 83 of the link 80 and rotating it,
As shown in FIG. 14, the count body 70 rotates by 36 degrees, the position of the opening 73 shifts, and the pin 82 relatively enters along the inner surface of the annular guide 72 of the count body 70.

Therefore, even if the 500 yen coin b is released from the coin receiving portion 57 of the coin receiving lever 50,
The pin 82 of the retaining link 80 engages the annular guide 72 of the counting body 70 and the retaining link 80
Since the pin 55 of the coin receiving lever engages with the groove 81 of the coin receiving lever, the clockwise rotation of the coin receiving lever 50 is restricted, thereby starting the 500 yen holding mechanism (see Figure 23). ).

(iv) The cam gear 30 further rotates, and as shown in FIG.
When it comes into contact with 0c, the coin receiver lever 50 rotates more counterclockwise than when it comes in contact with a 100 yen coin.
The 500 yen coin is released and falls through the detour 3c, and after pressing down the tip 142 of the detection lever 140, is ejected out of the machine from the ejection port 3e.

The counterclockwise rotation of the detection lever 140 causes the tamper prevention lever 130 to return to its original position, and the detection lever 140 returns to its original position, and the rotation of the detection lever generates one pulse from the microswitch. The same is true for 100 yen coins.

(v) Coin receiver lever 50 releasing 500 yen coin b
tries to rotate clockwise due to the weight of the weight 58 and the link 60, but the above-mentioned
Since the 500 yen holding mechanism has started, the rotation of the coin receiver lever 50 is restricted, and the lowering of the link 60 is also restricted, so that the count body 70 reaches 1.
Rotate the star wheel 10 and the cam gear 3 until the opening 73 is at the position of the pin 82 again.
0 will continue to rotate.

At this point, the coin cutter lever 100
The return to the original position is caused by the contact between the regulating plate 110 and the first pin 54 of the coin receiving lever 50, the contact between the stopper 110a of the regulating plate 110 and the coin receiving lever 50, and the contact between the slit 112 of the regulating plate and the coin receiving lever 50. Pin 106 of receiver lever
The next coin b' remains locked.

(vi) When the cam gear 30 further rotates from the state shown in FIG. 23 and the second tooth 32 of the intermittent gear 33 meshes with the small gear 83 of the holding link 80, the count body 70 further rotates as shown in FIG. It rotates by 36 degrees, and therefore the claws 75 etc. also rotate by 36 degrees. That is, the count body 70 rotates 1/5 as the small gear 83 of the holding link rotates half a rotation due to the engagement with the first and second gears 31 and 32 of the intermittent gear 33 due to one rotation of the cam gear 30. It's becoming like that.

(vii) The cam gear rotates further from the state shown in Fig. 24, and its back protrusion 3 again as shown in Fig. 25.
4 pushes up the tip 133 of the anti-tamper lever, the anti-tamper lever 130 swings counterclockwise as described above, and the detection lever 14
0 also oscillates.

Further, the pulse generating lever 150 rotates clockwise when its upper end 153 is pushed up by the horizontal portion 131 of the anti-tampering lever, and its lower end 152 is positioned in the rotation orbit of the claw 75 of the counter body 70, etc. becomes.

(viii) After that, the cam gear 30 further rotates, and the first and second teeth 31 and 32 of the intermittent gear 33 are rotated again.
meshes with the small gear 83 of the holding link 80, and the count body 70 rotates 1/5 turn. In this process, as shown in FIG. 16, the claw 75 and the lower end 152 of the pulse generating lever 150 engage, the pulse generating lever 150 swings counterclockwise, and its upper end pushes down the horizontal portion 131 of the tamper-proofing lever. ,
The detection lever 14 is activated by the hook portion 135 of the fraud prevention lever.
0 to return the fraud prevention lever 130 and detection lever 140 to their original positions.

This rotation of the detection lever 140 causes the microswitch 146 to generate one pulse, and the same operation is repeated four times.

In other words, if you insert a 500 yen coin,
The first pulse is generated when the 500 yen coin pushes down the detection lever 140, and the second pulse is generated when the claw 75 of the count body 70 engages with the pulse generation lever 150. Every 1/5 rotation, the third pulse is generated when the pawl 76 engages with the pulse generating lever 150, and the fourth pulse is generated when the pawl 77 engages.
The fifth pulse is generated by engagement with the pawl 78.

(ix) As described above, when the counter body 70 rotates once and its opening 73 comes to the position of the pin 82 of the holding lever 80 again, the coin receiving lever 50 is already moved counterclockwise by the 500 yen coin. Since the bias is no longer present, the coin receiver lever 50 rotates clockwise due to the action of the weight 58, the holding link 80 also rotates clockwise, and the pin 82 comes off from the counter body 70. Become.

At this time, the cam gear 30 is at a position of approximately four and a half rotations, so the coin receiver lever 50 does not swing.
As in the case of the 100 yen coin, the protrusion 51 is the cam body 4.
0 (not shown), and then the cam gear 30 completes 5 rotations, and the protrusion 51 of the coin receiving lever 50 comes into contact with the cam body as in the case of a 100 yen coin. When the link 60 comes into contact with the third cam surface 40c, the link 60 descends and the locking pawl 61 engages the locking portion 13 of the star wheel 10.
The pachinko balls are engaged again and the pachinko balls stop flowing down.

As a result, pachinko balls worth 500 yen were lent out.

At this point, as in the case of a 100 yen coin, if there is a next coin b', the coin receiver lever 50
When the protrusion 51 falls into the third cam surface 40c of the cam body 40, the locking of the next coin by the coin cutting mechanism is released, and if the next coin b' is a 500 yen coin, the above explanation will be made. Repeat the action,
If it is a 100 yen coin, the action of () explained earlier will be performed.

The fact that the cam gear 30 makes only four and a half revolutions when the count body 70 makes one revolution can also be seen from the positions of the first and second teeth of the intermittent gear 33 shown in FIGS. 10a and 10c. As shown, when the cam gear 30 rotates approximately half a revolution, the count body 70 has already been activated prior to one revolution of the cam gear 30.
This is because it rotates by 1/5.

As explained in () and () above, when a 100 yen coin or a 500 yen coin is inserted into this ball lending machine, the coin is inserted due to the difference in the amount of rotation of the coin receiver lever when receiving both coins. A certain number of pachinko balls corresponding to the coins inserted are automatically lent out, and a pulse signal is generated.The coin cutter mechanism ensures that even if coins are continuously inserted, each pachinko ball is automatically lent one by one. The pachinko balls are supplied to the coin receiving lever 50, and the number of pachinko balls that have been inserted are lent out. Furthermore, when a coin is not actually inserted, the lower surface of the coin receiver lever 50 is brought into contact with the stopper 110a of the regulation plate 110 at an almost right angle and is regulated, so it malfunctions due to vibration when a coin is not inserted. Don't wake up.

(Problems to be Solved by the Present Invention) However, in the ball lending machine proposed by the present applicant as described above, even when a 100 yen coin is inserted, the coin receiver lever 50 does not release the 100 yen coin. When the coin receiver lever 50 rotates excessively and the pin 82 of the holding link 80 completely enters the opening 73 of the counter body 70, the coin receiver lever 50 rotates excessively and the pin 82 of the holding link 80 completely enters the opening 73 of the counter body 70. If the clockwise rotation of the coin receiver lever 50 is delayed due to increased friction between the coin receiver lever and retaining link and its pivot due to long-term use, the intermittent gear 33 of the cam gear 30 and the retainer link The pin 82 of the holding link enters into the annular guide 72 of the count body 70 when the small gear 83 of 80 is engaged, and the 500-minute holding mechanism is activated, and even though only 100 yen coins have been inserted, 500
There is a risk that yen worth of pachinko balls may be rented out.

The purpose of this invention is to solve the above-mentioned problems with conventional ball lending machines, and to prevent pachinko balls worth 500 yen from being lent when a 100 yen coin is inserted.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides rotation regulation that prevents the coin receiving lever from rotating excessively when the coin receiving lever receives a 100 yen coin. We have provided means.

(Function) Since the ball lending machine of the present invention has the above-described configuration, when a 100 yen coin is received, the coin receiving lever does not rotate excessively due to the rotation regulating means.
Pachinko balls worth 500 yen will not be lent out by inserting yen coins.

(Example) The illustrated embodiment will be described below.

FIG. 1 is a front view showing the main parts of an embodiment of the ball lending machine of the present invention, and is different from the conventional ball lending machine shown in FIG. Since the structure is similar and the basic operation is also the same as the conventional one, the main parts of the present invention will be mainly explained below.

In this embodiment, the rotation regulating means for preventing excessive rotation of the coin receiving lever 50 is composed of a protruding plate 116 integrally formed on the regulating plate 110 and a V-shaped notch 59 formed on the coin receiving lever 50. has been done.

As shown in FIG. 1, the projecting plate 116 comes into contact with the lower edge of the coin receiving plate 50 at a substantially right angle when no coins are inserted, so that the projecting plate 116 does not hold any coins in place, similar to the conventional stopper 110a (see FIG. 9). It is possible to prevent the coin receiver lever 50 from malfunctioning when the coin receiver lever 50 is inserted, and when a 100 yen coin is inserted, it engages with the V-shaped notch 59 of the coin receiver lever 50 as described below, and the coin receiver lever 50 closes. 50 from rotating excessively.

Therefore, to explain the case where a 100 yen coin is inserted in this embodiment, as shown in FIG.
is rotated counterclockwise, the regulation plate 110 is rotated clockwise in response to this, and the coin receiving lever 50 is rotated counterclockwise until it receives the 100 yen coin a and locks the coin. do.

And 100 yen coin a is coin cutter lever 100
After passing through the protrusion 102 of the coin cutter lever 1
00 rotates clockwise and tries to return to its original position, but the vertical edge 114 of the regulation plate 110 comes into contact with the first pin 54 of the coin receiving lever, and the projecting plate 116 of the regulation plate 110 as shown in FIG. Since it comes into contact with the long side 59a of the notch 59 of the coin receiver lever, its rotation is restricted.

At this time, the tip 116a of the projecting plate 116 has entered the notch 59 of the coin receiving lever as shown in FIG. 3, but is in contact with the short side 59b of the notch. Further, the holding link 80 also rotates together with the coin receiving lever 50, and its pin 82
It almost enters the opening 73 of No. 0, but it does not completely enter, as in the conventional case.

Thereafter, as shown in FIG. 4, the cam gear 30 rotates, and the protrusion 52 of the coin receiving lever 50 falls from the first cam surface 40a of the cam body 40 to the stepped portion 42, and accordingly, the coin receiving lever 50 When the coin lever rotates counterclockwise to release the 100 yen coin a, in the case of a conventional ball lending machine, the coin receiver lever rotates until it comes into contact with the second cam surface 40b of the cam body ( (that is, excessive rotation), the pin 82 of the retaining link 80 was pushed into the opening 73 of the count body 70.
However, in this embodiment, as shown in FIG.
The tip 116a of the protruding plate 116 of 0 engages with the notch 59 of the coin receiving lever 50 and comes into contact with the short side 59b and the long side 59a to restrict excessive rotation of the coin receiving lever 50. The pin 82 does not completely enter the opening 73 of the count body. That is, in this example, the rotation of the coin receiver lever 50 is restricted, and the protrusion 52 does not come into contact with the second cam surface of the cam body.

Therefore, according to this example, pin 8 of the retaining link
2 does not completely enter the opening 73 of the counter body, so if for some reason (for example, increased friction between the coin receiver lever and the holding link and its pivot due to long-term use), the clock of the coin receiver lever 50 may become damaged. Even if the rotation in the direction is delayed, the intermittent gear 33 of the cam gear 30 and the small gear 83 of the holding link do not mesh, and the count body 70 also does not rotate, so the pin 82 does not move along the inner surface of the annular guide 72 of the count body. I never get into it.

Next, to explain the case where a 500 yen coin is inserted, as shown in FIG. . Here, since the 500 yen coin has a larger diameter than the 100 yen coin, the coin cutter lever 100 and the regulation plate 1 are
10 swings greatly, and as a result, as shown in FIG. Notch 59
Although the coin cutter lever 100 does not engage with the lower edge and does not come into contact with the lower edge, as shown in the figure, the coin cutter lever 100
It comes into direct contact with the 500 yen coin b and restricts its rotation in the clockwise direction.

After that, as shown in FIG. 7, the cam gear 30
rotates, and when the protrusion 52 of the coin receiving lever falls into the stepped portion 42 of the cam body and comes into contact with the second cam surface 40b, the 500 yen coin also falls slightly as shown in the same figure, so the 500 yen coin b Coin cutter lever 1
00 is no longer in contact with the coin cutter lever 100.
attempts to rotate clockwise, but at this time, the tip 116a of the protruding plate of the regulation plate comes into contact with the lower edge of the coin receiving lever 50 as shown in the same figure. Rotation will still be restricted. Also, here, the projecting plate 116 does not engage with the notch 59. Therefore, in this state, the cam gear 3
When 0 rotates further, the 500 yen holding mechanism starts as in the conventional case.

One embodiment of the present invention has been described above, but
The present invention is not limited to the above embodiments, but can be modified as appropriate within the scope of the gist of the present invention.

For example, the shapes of the protruding plate and the notch serving as the rotation restricting means are not limited to those shown in the drawings, and may be any shape as long as they can prevent excessive rotation of the coin receiving lever through engagement.
Further, the rotation regulating means may directly regulate the holding link 80 instead of using the projecting plate of the regulating plate 110 and the notch 59 of the coin receiving lever 50.

In addition, when inserting a 500 yen coin, the timing at which the 500 yen coin releases contact with the coin cutter lever 100 and the timing at which the projecting plate 116 of the regulation plate contacts the lower edge of the coin receiving lever 50 are finely adjusted. Therefore, as shown in FIG.
It is better to install 2a protrudingly.

(Effects of the invention) As detailed above, according to the invention, the coin receiver lever does not rotate excessively when a 100 yen coin is received, so when a 100 yen coin is inserted, a pachinko machine worth 500 yen is Balls are never lent out.
