The medal payout device 6 is provided with a hopper 61 functioning as a storage unit for storing medals, and the medal inserted from the medal insertion slot 2 is detected by the medal selector 10 and guided to the hopper 61. It has become.

[Main control unit]
The main control unit 7 includes a main board on which a control chip in which a main CPU, a main ROM, a main RAM, and the like are integrated is mounted, a board case for containing the same, and the like. By controlling each device such as the drum unit 4 and the medal payout device 6 based on the signal from the medal selector 10, the following slot machine game is advanced.

Specifically, when a player inserts a medal from the medal insertion slot 2, the medal is detected by the medal selector 10, and a detection signal is input to the main control unit 7. When the bet button 2 a is operated, the operation signal is input to the main control unit 7. The main control unit 7 monitors the number of medals that can be played from the presence or absence of the input of these signals, and monitors the operation of the start lever 3.
When the start lever 3 is operated when the number of medals that can start the game is reached, the main control unit 7 controls the drum unit 4 to rotate the reels 41a, 41b, and 41c.

  Furthermore, when the start lever 3 is operated, the main control unit 7 selects from among a plurality of winning combinations (including losing) such as a bonus combination, a small combination, and a re-play combination, which is a starting combination to shift to a bonus game. Make an internal lottery to determine the lottery result of this game before stopping the reel 41 in advance, and stop with a combination of symbols according to the lottery result based on the timing when each stop button 5a, 5b, 5c is pressed. And stop control of the reels 41a, 41b, and 41c which are rotating.

  Further, the main control unit 7 determines a combination of symbols stopped and displayed on each of the reels 41a, 41b and 41c, and in the case of a predetermined combination of symbols, controls to pay out a predetermined number of medals to the medal payout device 6. And pay out the medal from the medal payout opening 6a.

  Further, in the slot machine 1, in the slot machine game as described above, the main control unit 7 performs predetermined control signals at predetermined game timing (for example, start lever operation, stop button operation, bonus game start, bonus combination winning, etc.) Is output to the sub-control unit 8 so that the sub-control unit 8 controls notification means such as the display 9a, the speaker 9b, the lamp 9c and the like based on the effect program stored in advance according to the control signal. It is designed to perform game effects.

  The control signal output from the main control unit 7 to the sub control unit 8 includes, for example, a control signal indicating progress of the game such as start lever operation, stop button operation, start of a bonus game, etc. There are a winning target signal indicating a lottery target (for example, a type of a winning bonus combination [big bonus, regular bonus], a type of a small winning combination won, a signal indicating a re-playing combination, a loss, etc.) and the like.

[Sub control unit]
The sub control unit 8 is configured as a computer in the same manner as the main control unit 7, and performs predetermined display effects and sound effects by controlling the display 9a, the speaker 9b, the lamp 9c, and the like.
The sub control unit 8 is composed of a sub substrate on which a presentation chip such as a sub CPU, a sub ROM, a sub RAM, etc. is mounted, and a substrate case that accommodates this, and the sub CPU executes the program stored in the sub ROM By doing this, the display effect is performed on the display 9a in a predetermined display mode, and predetermined sound data is output from the speaker 9b, and the lighting control of the lamp 9c is performed.

The sub control unit 8 operates as follows based on the control signal from the main control unit 7.
For example, when a control signal indicating the winning of a bonus combination is received as a winning target signal indicating a lottery target selected as a result of an internal lottery from the main control unit 7, the display 9a is controlled to perform display effect relating to bonus winning . After the transition to the bonus game, the lamp 9c blinks at a predetermined timing, and a predetermined effect sound such as fanfare sound is output from the speaker 9b.

  The slot machine 1 of the present embodiment has the following characteristic configuration in the medal selector 10 for detecting a medal inserted from the medal insertion slot 2 in addition to the configuration of such a normal slot machine. .

[Medal selector]
The medal selector 10, as shown in FIGS. 4 (a) and 4 (b), includes a main body 10a and a cover member 10b attached to the main body 10a so as to be openable and closable. ing.
A medal inlet 19a communicating with the medal insertion slot 2 is provided at the top of the medal selector 10, and the medal inserted from the medal insertion slot 2 is taken into the medal selector 10 from the medal entrance 19a.
Further, on the right side surface of the medal selector 10, a medal outlet 19b which is an outlet of the medal taken into the medal selector 10 is provided. The medal outlet 19 b communicates with the medal inlet 19 a in the medal selector 10, and the medals flowing from the medal inlet 19 a pass through the medal selector 10 and flow out from the medal outlet 19 b. Further, the medals flowing out from the medal outlet 19 b are guided to the hopper 61 while being guided by a predetermined guiding path.
Further, the cover member 10b is mutually displaceable in the closed state (FIG. 4 (a)) and the open state (FIG. 4 (b)) with the shaft 21 as a fulcrum, and between the main body 10a and the closed state. To form a flow path through which medals can pass from the medal inlet 19a to the medal outlet 19b, and in the open state, the medals packed in the medal selector 10 are discharged from the lower side (Y direction in FIG. 6A). Form an opening.

Here, the passage route of the medal in the medal selector 10 will be described with reference to FIGS.
The medals flowing in from the medal inlet 19a pass through the flow path 111, the flow path 112, the blocker 13, and the flow path 113 in this order to reach the medal outlet 19b.
The channel 111 is formed as a route through which the medals flow substantially along the vertical direction, and the channels 112 and 113 and the blocker 13 are formed as routes through which the medals flow along the slope.
The blocker 13 functions as a bridge that is bridged between the flow path 112 and the flow path 113, and supports the medal passing therethrough from below.

However, the blocker 13 is controlled by the solenoid 12 provided on the back surface of the main body 10a (see FIG. 4C) and protrudes from the flow passage so as to support the lower peripheral surface of the medal, and It is configured to be respectively displaceable in a configuration in which it can not support the base and retracts into the channel.
FIGS. 5 and 6 (b) show the form of the blocker 13 when the lower peripheral surface of the medal protrudes downward from the flow passage, and FIG. 6 (a) shows the flow of the lower peripheral surface of the medal uncontrollable. It shows the form of the blocker 13 when moving backward into the road.
With such displacement, in the state shown in FIGS. 5 and 6 (b), the blocker 13 functions as a bridge that is bridged between the flow path 112 and the flow path 113, thereby flowing in from the medal entrance 19a. The medal can be reached to the medal outlet 19b, and in the state shown in FIG. 6 (a), the medal lacks the support by the blocker 13, that is, the inclined surface (rolling surface) disappears. It falls in the Y direction and is released from the medal selector 10 to the outside. The released medals are discharged from the medal payout opening 6a to the outside of the machine.
In the following description, the form of the blocker 13 protruding from the flow passage so as to support the lower peripheral surface of the medal is a "permissible form" which permits passage of the medal, and the lower peripheral surface of the medal can not be supported in the flow passage The form of the blocker 13 which has been set back is referred to as a "prohibited form" in which the passage of the medal is prohibited.

On such a passing route of medals, detection means for detecting the medals flowing from the medal entrance 19a, and sorting means for selecting the authenticity of the medals based on the difference in size thereof are provided.
As detection means, tread plate switches 14 and 15 provided on the upstream side and the downstream side, an optical sensor 16 and a lever switch 17 are provided.
The tread plate switches 14 and 15 and the lever switch 17 are contact type detection means for detecting passage of medals by the medals coming in direct contact with these, and the optical sensor 16 (photo interrupter) is, for example, It is a non-contact type detection means which detects passage of a medal by change to a light blocking state.
For example, when detection of passage of medals is detected in the order of the footboard switch 14, the footboard switch 15, the optical sensor 16, and the lever switch 17, these detection means are determined to be inserted by the main control unit 7, When passing of the medal is detected without following this order, it is determined that the medal is abnormal without being determined that the medal is inserted.

As the sorting means, the blocker 13, the guide plate 20, and the recess 20a are provided.
The guide plate 20 is configured to be able to support the upper peripheral side of the medal, which is supported by the blocker 13 in the acceptable form. However, the supportable medals are medals of a diameter larger than the diameter d1 shown in FIG. 6 (b), and medals smaller than this and smaller than the prescribed size are not supported.
In the lower part of the guide plate 20, a recess 20a formed as a recess is provided. Further, in the cover member 10b, an urging member (a tread plate) for urging the medal on the concave portion 20a side is provided on the surface facing the concave portion 20a (not shown).
With such a configuration, the medals not supported by the guide plate 20 will tilt toward the main body 10a side, that is, toward the concave portion 20a, which causes the support by the blocker 13 to be lost, and falls in the Y direction. The medal selector 10 is released to the outside until it reaches detection means such as the footboard switch 15 positioned downstream of the blocker 13.
Thus, the medal having a diameter smaller than the diameter d1 is discharged from the medal selector 10 by the sorting means, and only the medal having a diameter larger than the diameter d1 can pass through the passing route. However, there is also an upper limit to medals having a diameter larger than the diameter d1, and medals having a diameter larger than the opening width of the medal insertion slot 2 can not be inserted into the medal insertion slot 2.

  Furthermore, in addition to the detection means and the sorting means, the following characteristic configuration is provided on the medal passing route.

[Step]
On the upstream side of the sorting means, a step d2 is provided for allowing the medals passing through the channel 112 to fall freely.
As shown in FIGS. 6 (b) and 6 (c), the step d2 is formed between the downstream end 112a of the flow passage 112 and the blocker 13 in the allowable form. About 1 mm is provided.
If smooth flow of medals is desired, it is preferable that there is no step, but it is provided for the following reasons.

If there is no step, the medals flowing down the vicinity of the guide plate 20 flow down while the lower peripheral surface of the medal contacts the flow path 112 and the blocker 13 in the allowable form.
Since the medal lower peripheral surface is supported by the blocker 13 while being urged toward the concave portion 20a by the urging member (not shown), the medal flows down in a relatively stable posture. Become.
Such medals will reach the channel 113 before losing the balance until they are inclined to the concave portion 20a side, and then the medals which are not sorted by the sorting means despite the diameter being smaller than the diameter d1. The inconvenience of appearance will occur.
In order to prevent such a problem, in addition to biasing the recess 20a with the biasing member, it is necessary to make the posture of the medal during the flow further unstable and to break the posture of the medal.
Therefore, in the present embodiment, the step d2 is provided on the upstream side of the sorting means. Such a step d2 causes the falling medals to freely fall from the downstream end 112a of the flow passage 112 to the blocker 13 in an acceptable form.
Since the lower peripheral surface of the medal is not supported by the blocker 13 in this free fall, that is, in the floating state in the air, only the urging force to the concave portion 20a side by the urging member is except gravity. By acting on the medals, it is possible to force the medals to fall to the concave portion 20a side.
As a result, the function of sorting the medals by the sorting means is effectively exhibited, and medals less than the prescribed size (diameter d1) are excluded from the medal selector 10.

Also, due to such free fall, the medal that has landed on the blocker 13 will be bound by the impact and break its posture.
Also by this, the function of selecting the medals is effectively exhibited, and the medals less than the prescribed size (diameter d1) are excluded from the medal selector 10.

[S-shaped flow path]
As shown in FIG. 6, in the flow path 111 located on the upstream side of the step d 2, the protrusion 111 a that protrudes to the flow path side so as to narrow the flow path and the receding so as to widen the flow path on the downstream side A relief portion 111 b is provided. The combination of the projecting portion 111a and the relief portion 111b located downstream from this causes the medals flowing down the flow path 111 to flow down along a substantially S-shaped locus.
Thus, the momentum of the medals flowing down the channel 111 can be reduced until the step d2 and the stability of the posture of the medal is further impaired, so that the function of the sorting means is easily exhibited.

[stopper]
A stopper 18 is provided between the blocker 13 and the flow path 113.
The stopper 18 operates as a blocking means capable of blocking the flow of the medals passing through the flow paths 111, 112 and the blocker 13 in the allowed form into the hopper 61.
Specifically, as shown in FIGS. 7 and 8, the stopper 18 has an acceptable form (FIG. 7 (a), FIG. 8 (a)) in which the flow of the medal into the hopper 61 can be tolerated, and the hopper 61 of the medal. It is displaceable in a blocking form (FIGS. 7 (b) and 8 (b)) capable of blocking the flow down.

  Such displacement of the stopper 18 is interlocked with the operation of the blocker 13, and when the blocker 13 is in the allowable form, that is, the form in which the blocker 13 protrudes from the flow passage so as to support the lower peripheral surface of the medal, as shown in FIG. (A), as shown in FIG. 8 (a), the stopper 18 displaces the flow of the medal into the hopper 61 to an acceptable allowable form, and the blocker 13 is a prohibited form, that is, the blocker 13 is the lower peripheral surface of the medal 7B and 8B, the stopper 18 is displaced to a blocking configuration capable of blocking the flow of the medal into the hopper 61, as shown in FIGS. 7 (b) and 8 (b).

Since the blocker 13 is also acceptable if it is such an acceptable form of the stopper 18, the medals flowing in from the medal entrance 19a can be formed by the flow path 111, the flow path 112, the blocker 13, the stopper 18, and the flow path 113. The medal exit 19b can be reached through in order.
Further, at this time, passage of medals is sequentially detected in the order of the tread plate switch 14, the tread plate switch 15, the optical sensor 16, and the lever switch 17.
On the other hand, if the stopper 18 is in the blocking mode, since the blocker 13 is in the prohibited mode, the medals flowing from the medal entry port 19a can not pass through the blocker 13 and fall in the Y direction. The medal selector 10 is released to the outside until it reaches. At this time, since the medals falling in the Y direction can not reach at least the lever switch 17, it is not determined that the medals are inserted.

However, in the middle of the blocker 13 shifting from the allowed mode to the prohibited mode, a medal may be present on the blocker 13, and such a medal may flow as it is due to inertia during flow-down even if the support by the blocker 13 is lost. Try to move towards road 113.
Such timing occurs when medals are continuously inserted from the medal insertion slot 2.

For example, since the upper limit of the credit medal is 50 medals, the 50th and 51st sheets are inserted successively, and the passage of the 50th medal is detected by, for example, the lever switch 17 (FIG. 14) (Refer to (b)) The blocker 13 is controlled to shift from the allowed mode to the prohibited mode, but at this timing, the 51st medal may be present on the blocker 13.
Thus, on the way the blocker 13 is displaced from the permissible form to the forbidden form, a medal may be present on the blocker 13 and such a medal may be released by the inertia during the flow even if the support by the blocker 13 is lost. It tries to move toward the channel 113 as it is.

Furthermore, while the blocker 13 is displaced from the permitted mode to the prohibited mode, the main control unit 7 determines that the blocker 13 has already been displaced to the prohibited mode, and the tread plate switch 15, the optical sensor 16, and the lever switch 17 are used. Control to ignore the detection of medals.
Then, the above-mentioned 51st medal arrives at the medal outlet 19b without being determined to be inserted, and is stored in the hopper 61. As a result, the player suffers a loss. .

In order to avoid the occurrence of such an event, a stopper 18 is provided on the downstream side of the blocker 13 and on the upstream side of the lever switch 17.
By providing the stopper 18 at this position, while the blocker 13 is displaced from the allowed mode to the prohibited mode, the medal existing on the blocker 13 tries to move toward the flow path 113 as it is, but during the movement thereof By displacing the stopper 18 in the blocking mode, the movement to the flow path 113 is blocked, and the medal outlet 19 b can not be reached. As a result, the medal falls in the Y direction and is released from the medal selector 10 to at least the lever switch 17 and returned to the player from the medal payout opening 6b, so that the player loses a loss. You will not suffer from

By providing the stopper 18 in this manner, the medals present on the blocker 13 (51, for example, the displacement after the lever switch 17 detects the 50th medal) while the blocker 13 is displaced from the permissible mode to the forbidden mode. The first medal can be released from the medal selector 10 to the outside. However, there are cases where some medals (fifth medals) having a slow flow-through speed can not pass through the stopper 18 (see FIG. 14B).
At such a timing, the stopper 18 is in the process of displacing from the allowed form shown in FIG. 8A to the blocked form shown in FIG. 8B, and is displaced from the allowed form to the blocked form while narrowing the channel width. Therefore, at that time, as shown in FIG. 9, the stopper 18 may pinch the medal M (the 50th medal) with the tread plate 15.
If such pinching occurs, the medal M will stop on the spot, and a "medal clogging" will occur, which may hinder the progress of the slot machine game.
Therefore, even if such pinching occurs, the following characteristic configuration is provided so that the medal M can be released from the pinching due to the inertia and the own weight during its flow.

In the stopper 18, the opposing surface 181 that faces the inserted medal is a portion that contacts the medal, and the shape of the opposing surface 181 is characteristic.
FIG. 9B shows the stopper 18 before the shape of the facing surface 181 is improved. In this stopper 18, the upper end portion 181a of the facing surface 181 is a portion in contact with the medal.
On the other hand, FIG. 9A shows the stopper 18 after the shape of the opposing surface 181 has been improved, and in this stopper 18, the lower end portion 181b of the opposing surface 181 is in contact with the medal.
That is, the stopper 18 has different positions in contact with the medal before and after the improvement, and although the stopper 18 is shaped to abut against the center of the medal before the improvement, the stopper 18 It has been improved to be in contact with the shape.
Such improvements have been made, as will be described below, by causing the medals to flow down by inertia or dead weight without completely stopping the inertia of the medals which are going to flow down while being held between the stoppers 18, This is to prevent the occurrence of the “medal clogging” due to the 18 pinches.

Here, assuming that the force with which the stopper 18 clamps the medal is a braking force for stopping the medal, if the braking force is the same, it is more likely to act on the peripheral portion of the medal than on the center of the medal. However, the action and effect as a braking force is low.
In other words, if the point of action of the braking force is set near the center of gravity of the medal, that force will act on the entire medal, effectively acting as a force to stop the medal, but acting on the rim of the medal When set as a point, the force does not act on the entire medal, and hence the effect as a braking force is less than that on the center of gravity.
That is, since the medal pinching by the stopper 18 is a very rare event such as when the blocker 13 is in the process of being displaced from the permissible mode to the forbidden mode and there are some medals having a slow flow-down speed, In the improved stopper 18, the necessary minimum braking force is applied to the medal without degrading the original function as the blocking means, and this pinching is prevented from developing into "medal clogging".

Furthermore, in order to prevent pinching by the stopper 18, as described above, not only the shape of the facing surface 181 is improved, but the following features are provided in the inclined surface (rolling surface) where the medals flow down.
FIG. 8C is a cross-sectional view of the stopper 18 in the allowable form, taken along the line A-A. As can be seen from this, between the blocker 13 (first flow path) in the allowable form and the flow path 113. The slope of the flow path has changed.
In particular, the top surface 180 of the stopper 18 functions as a rolling surface of the medal, ie, a game medium (medal) passage portion (part of the second flow path) through which the medal passes. Starting from the end portion 180a, the inclination of the rolling surface is steep (a steep inclination) by an angle α.
Furthermore, on the downstream side of the stopper 18, the top surface 240 of the fixing member 24 between the stopper 18 and the lever switch 17 is also the rolling surface of the medal, that is, the game medium (medal) passing portion through which the medal passes. However, the top surface 240 is also on the extension of the top surface 180 and has the same slope as that of the top surface 180 (see FIGS. 10A and 10B).
That is, the rolling surface formed by the top surface 180 and the top surface 240 is steeper than the blocker 13 in the allowable form. That is, the top surface 180 and the top surface 240 (the second flow channel) are steeper than the blocker 13 (the first flow channel), and the stopper 18 is a flow channel on the steep side (the second flow It is provided corresponding to the road) and is located at the change point of the gradient.

With such a configuration, since the acceleration of the medal increases from the change point of the gradient and the passing medal gets momentum, it becomes difficult for the stopper 18 to pinch the medal, and the pinching can be effectively prevented.
In addition, even if the stopper 18 is inserted, since the top surface 180 of the stopper 18 is positioned on the change point of the gradient, the inserted medal is not well seated and lacks stability, and the inserted state It will promote the release of
In the present embodiment, the stopper 18 is disposed at the change point of the gradient, but the stopper 18 may be provided in the flow path (second flow path) downstream of the change point. Thereby, at the time of passing the stopper 18, the acceleration of the passing medal is increased, and the passing medal is given momentum, so that the pinching can be prevented.
In addition to the improvement of the shape of the facing surface 181 and the change of the gradient, the prevention of the pinching is preferably adjusted by, for example, reducing the constant of the spring for urging the stopper 18 toward the blocking mode.

[Lever switch]
Among the footboard switch 14, footboard switch 15, optical sensor 16, and lever switch 17, detection means provided on the most downstream side is the lever switch 17.
The lever switch 17 is displaced as shown in FIG.
FIG. 10 (a) shows the form of the lever switch 17 in the no-load state, and at this time, it protrudes upward from the flow path 113 to block passage of the medal.
FIG. 10 (b) shows the form when the medal M is depressed by the peripheral surface of the medal M and receives the weight of the medal M as shown in FIG. 10 (c). To allow the passage of medals.
And passage of a medal will be detected by displacement of lever switch 17 from a form shown in Drawing 10 (a) to a form shown in Drawing 10 (b). Here, a mechanism of passage detection of the medal by the lever switch 17 will be described.

FIG. 11 is a perspective view of the lever switch 17, and FIG. 12 is a perspective view showing the positional relationship between the lever switch 17 and the detection means.
The lever switch 17 is an example of a rotation member, and is used for rotation of the bearing 170 supported by the rotation shaft 22, a contact portion 171 that is in contact with the passing medal and pushed down by the passing medal, and the lever switch 17. It has displacement according to, and the to-be-detected part 172 with which the displacement is detected by the optical sensor 23 is provided.
FIG. 11 shows the lever switch 17 in a no-load state, and the contact portion 171 is turned in the A direction by being pushed down by the passing medal. Further, although not shown, the lever switch 17 is biased by biasing means such as a spring, and when released from the weight by the passing medal, restores the posture to the no-load state.

The light sensor 23 is a photo interrupter having a light emitting portion and a light receiving portion for receiving light from the light emitting portion. When the light from the light emitting portion is blocked by the detected portion 172, the lever switch 17 is not loaded. When the detected portion 172 is displaced to a position where the light receiving portion can detect light from the light emitting portion, the contact portion 171 is pushed down in the A direction by the passing medal. It detects the event (Fig. 12 (b)).
That is, the light sensor 23 detects passage of the medal from the change from light shielding to passing light.

The lever switch 17 for detecting passing medals with such a configuration has the following problems due to its configurational characteristics.
Specifically, when an impact or vibration is externally or directly applied to the medal selector 10 from the outside, the lever switch 17 is displaced in the A direction, and the medal is not actually passed though it does not pass. An erroneous operation of detecting the passage of
As an example of such an act of giving an impact or vibration, for example, an action of a player hitting the slot machine 1 to apply an impact or an illegal person causes a foreign object to intrude from a gap between the front door 1a and the case 1b. There is an act of directly vibrating the medal selector 10 or the like.
Although an improvement is expected by changing the spring constant for biasing the lever switch 17 to the no-load state as a countermeasure against such a malfunction, if the spring constant is made too large, the no-load lever switch 17 Since it becomes a form which interrupts passage of a medal, there existed a possibility that new harmful effects, such as medal clogging, may arise.
Therefore, the following characteristic configuration is provided so that the lever switch 17 does not rotate in the A direction even when an impact or vibration is given from the outside.

The lever switch 17 performs a so-called seesaw-like operation since it is displaced from the form of no load condition to the form to be depressed by receiving the weight of the passing medal, that is, displacement in the A direction.
Therefore, the position of the center of gravity of the lever switch 17 is adjusted so as to increase the moment of inertia in the unloaded state.

FIG. 11 (b) shows the lever switch 17 before improvement, and FIG. 11 (a) shows the lever switch 17 after improvement.
When these are compared, it turns out that the lever switch 17 after improvement is equipped with the weight addition part 173 which does not exist before improvement.
The weight adding portion 173 operates as an example of the suppressing means, is the lowermost end along the gravity direction of the lever switch 17, and holds the bearing 170 so as to maintain a weight balance with the contact portion 171. It is provided on the opposite side of the contact portion 171.
That is, in the lever switch 17 after the improvement, the position of the center of gravity of the lever switch 17 is closer to the bearing 170 than the state before the improvement, and is also closer to the lower side of the bearing 170 along the acting direction of gravity.

The reason for this improvement is that the lever switch 17 performs the same operation as a so-called pendulum pivoting in the vertical direction, so that the center of gravity is located lower than the bearing 170 in the vertical direction. This is because the inertia moment in the unloaded state is increased, and it becomes difficult to rotate even if an external impact is applied, and the stationary state is to be maintained.
As a result, the lever switch 17 is not displaced in the A direction by receiving an impact or vibration from the outside, and the medal does not actually pass (the contact portion 171 is not in contact), An erroneous operation of detecting passage of medals is prevented.

  Also, in addition to adjusting the position of the center of gravity so that the lever switch 17 does not rotate in the A direction when an external impact is applied, the lever switch 17 is depressed by an impact instead of or in addition to this. It is preferable to provide a control unit that controls the

FIG. 13 is a view showing the periphery of the lever switch 17. However, as can be seen from this, a protrusion 113a is provided on the wall on the flow path 113 side located on the right side of the lever switch 17.
The convex portion 113 a operates as a restricting portion which is an example of the suppressing means, and protrudes from the wall portion on the flow path 113 side toward the lever switch 17 so as to hinder the pivoting of the lever switch 17 in the A direction ( It is provided convexly).
In the case of the medal selector 10 of the present embodiment, the lever switch 17 tends to move in the X direction shown in FIG. 13B when receiving an external impact, so the flow path 113 side located on the X direction side The projection 113a is provided on the wall of the

By providing such a convex portion 113a, the medal selector 10 receives an impact from the outside, and even if the lever switch 17 tries to rotate in the A direction, it also moves in the X direction by this impact, so the convex portion 113a Thus, the rotation in the A direction is restricted.
As a result, the lever switch 17 is not displaced in the A direction by receiving an impact or vibration from the outside, and the medal does not actually pass (the contact portion 171 is not in contact), An erroneous operation of detecting passage of medals is prevented.
In addition, even when a fraudulent action of invading a foreign object such as a wire or the like from the medal insertion slot 2 toward the flow path 113 is performed, the lever switch 17 is pushed in the X direction by such a foreign object. Even if the switch 17 is rotated in the A direction, the rotation in the A direction is restricted by the convex portion 113a.

In addition, the movement to the X direction side of the lever switch 17 is minimized in the depression from the actual passage of the medal, that is, the displacement from the no-load state shown in FIG. 14A to the depressed state in FIG. Thus, the rotation in the A direction is not restricted by the convex portion 113a.
Further, in the case of the medal selector 10 of the present embodiment, the lever switch 17 tends to move in the X direction when receiving an impact from the outside, so the wall portion on the flow path 113 side located to the right of the lever switch 17 If the lever switch 17 tends to move in the direction opposite to the X direction, the protrusion 113a should be provided on the wall of the blocker 13 located on the left side of the lever switch 17. Is preferred.

In the slot machine 1 provided with such a medal selector 10, the following effects are exhibited.
For example, since the blocker 13 and a flow path (top surfaces 180 and 240) having a steeper slope than this are provided, and the stopper 18 is provided on the flow path (top surfaces 180 and 240), the flow path Since the acceleration of the passing medal is increased from the top surfaces 180 and 240 and the momentum is obtained, pinching of the medal by the stopper 18 is prevented.
Further, by providing the stopper 18 at the boundary between the blocker 13 and the flow path (the top surfaces 180 and 240), the stability of the medal located on the stopper 18 can be impaired, so that the medal pinching by the stopper 18 is suppressed. Be done.

Further, even if an external impact or vibration is applied to the medal selector 10 directly or indirectly, the moment of inertia of the lever switch 17 inhibits the rotation, so that the medal does not actually pass. Nevertheless, the false operation of detecting passage of medals is prevented.
In addition, by providing a restricting portion that restricts rotation at a position corresponding to the behavior of the lever switch 17 due to impact, vibration, intrusion of foreign matter or the like, erroneous operation can be effectively prevented.

[About the caulking member attached to the rotating shaft]
Next, a medal selector (referred to as a medal selector 10A) is provided with a caulking member 30 capable of fixing the pivot shaft 22 of the lever switch (pivot member) 17 and making it difficult to remove the covers etc. Will be described with reference to FIGS.
FIG. 15 is a rear view of the medal selector 10A, FIG. 16 is a rear perspective view of the medal selector 10A, and FIG. 17 is an exploded view of main parts of the medal selector 10A.
As shown in FIGS. 15-17, the medal selector 10A is configured to attach a caulking member 30 having a characteristic shape to the end of the pivot shaft 22A.

The caulking member 30 is made of a transparent resin member such as plastic and, as shown in FIG. 18, a cylindrical portion (referred to as a first cylindrical portion 31) into which the pivot shaft 22A can be inserted and a first cylindrical portion 31. A tubular portion (referred to as a second tubular portion 32) extending in the axial direction of the cylinder and a square plate shaped portion (referred to as a bowl shaped portion 33) provided on the longitudinal side of the second tubular portion 32 are integrated. It is formed.
The first cylindrical portion 31 and the second cylindrical portion 32 communicate with each other in the internal space, and for example, an open end (referred to as a second open portion 37) of an end of the second cylindrical portion 31 to an end of the first cylindrical portion 31 A cavity is formed over the open portion (referred to as a first open portion 36) of
A V-shaped groove is provided along the outer peripheral surface at the boundary between the first cylindrical portion 31 and the second cylindrical portion 32, thereby making the thickness thinner than the other portions (about 0.3 mm in thickness A portion (referred to as a thin groove portion 34).
Inside the first cylindrical portion 31, two triangular claw portions 35 are respectively provided at opposing positions so as to protrude from the inner wall portion.

The pivot shaft 22A is a metal round bar member for pivotally supporting the lever switch 17. As shown in FIG. 19, the pivot shaft 22A is divided into a shaft main body 221, a shaft front portion 222, and a shaft rear portion 223, As a whole, it has a thickness (outer diameter) which can be inserted into the first cylindrical portion 31.
However, the shaft front portion 222 forms a recessed portion 224 recessed by reducing the outer diameter between the shaft main body 221 and the tip end portion 225, and the front side of the tip end portion 225 is tapered.

According to such a caulking member 30 and the rotary shaft 22A, as shown in FIG. 20 (a) → (b), the rotary shaft 22A and the caulking member can be simply inserted into the caulking member 30. 30 can be coupled inseparably.
This coupling structure will be described with reference to FIG.
FIG. 21 (a) is a cross-sectional view of the pivot shaft 22A and the caulking member 30 before coupling.
Here, as shown in FIG. 21 (b), when the pivot shaft 22A is inserted into the inside of the first cylindrical portion 31, the pivot shaft 22A is brought into contact with the claw portion 35 by the tip end portion 225, Passage is blocked once.
However, by further pushing in the rotation shaft 22A, the tip end portion 225 presses the claw portion 35, whereby the claw portion 35 can be temporarily reduced by its elasticity (elasticity by the resin member).
Thereby, as shown in FIG. 21C, the tip end portion 225 can pass over the claw portion 35.
Further, thereby, the claw portion 35 is released from the pressing by the tip end portion 225, returns to the original shape (the shape protruding from the inner wall portion), and fits in the recess of the concave portion 224 (see FIG. 21C).
As a result, the concave portion 224 of the pivot shaft 22A and the claw portion 35 of the caulking member 30 can be brought into a coupled state of engagement.
In such a "coupled state", even if the pivot shaft 22A is pulled out from the caulking member 30, the claw portion 35 prevents the movement of the distal end portion 222, so it can not be pulled out.
Further, for example, even when inserting a rod-like member from the second opening portion 37 and pushing out the rotation shaft 22A stored in the first cylindrical portion 31, the claw portion 35 similarly moves the tip portion 222. It can not be pushed out to prevent it.
Therefore, the pivot shaft 22A can be fixed without using a dedicated member called an E-ring (retaining ring) which is conventionally used as a fastener for the pivot shaft.
In the state where the caulking member 30 is attached to the pivot shaft 22A as shown in FIG. 21 (c), the caulking member 30 has a portion b protruding from the tip end portion 225 of the pivot shaft 22A. The thin groove 34 is disposed at a predetermined position (a position close to the tip end portion 225) of the protruding portion b.

The method of attaching the caulking member 30 will be described with reference to FIGS. 16, 17, and 22-27.
As shown in FIG. 17, in the medal selector 10A, an optical sensor 23 capable of detecting the displacement of the detected portion 172 accompanying the rotation of the lever switch 17 is provided in advance on the back side of the main body 10a. It is assumed that a support member (a predetermined support member of the present invention) 102 for supporting the rotation shaft 22A for supporting the shaft is provided at a predetermined position (below the light sensor 23).
Among them, the support member 102 includes two support members erected in parallel in the main body 10a (the one disposed outside the medal selector 10A is placed inside the one outside the support member 102a and the inside placed inside the medal selector 10A). The pivot shaft 22A is supported in such a manner as to be bridged between the two support members 102.
Specifically, the outer supporting member 102 a and the inner supporting member 102 b are respectively provided with openings 103 at corresponding positions, and the pivot shaft 22 A is supported in a state of being inserted into each of the openings 103.
Further, a tubular member (hereinafter, referred to as a tubular cover 104) is integrally formed outside the opening 103 of the outer support member 102a.

The caulking member 30 is attached together with related parts such as the pivot shaft 22A, the lever switch 17, and the cover 50.
Therefore, with the state shown in FIG. 17 in which all the related parts are not attached as an initial state, the method of attaching the caulking member 30 will be described in the order of FIG. 22, FIG. 23, FIG.
The cover 50 (cover member of the present invention) is an L-shaped protection member made of transparent resin, and a rectangular plate-like fixing portion 51 (fixing means of the present invention) is integrally formed below. A rectangular plate shaped wall 52 (a shielding part of the present invention) is formed on the side of the fixing part 51.
The cover 50 covers the light sensor 23 (light emitting unit and light receiving unit), a part of the lever switch 17 (detected unit 172 etc.), and various detection means (detection It is also attached so as to cover the means a).

First, as shown in FIG. 22, the lever switch 17 is disposed at a predetermined position (see FIGS. 17 and 22).
Specifically, the lever switch is positioned so that the bearing 170 is positioned between the outer support member 102 a and the inner support member 102 b and the detected portion 172 is positioned between the light emitting portion and the light receiving portion of the light sensor 23. Arrange 17

Next, as shown in FIG. 23, the cover 50 is disposed at a predetermined position, and the fixing portion 51 is fixed by the screw 53 (see FIGS. 22 and 23).
Thereby, the cover 50 is attached so as to cover the light sensor 23, a part of the lever switch 17, and the detection means a such as the optical sensor 16 and the optical sensor 16.
According to such a cover 50, it is possible to make external access to the detection means a difficult, so that the detection means a can be protected.

Subsequently, as shown in FIG. 24, the caulking member 30 and the pivot shaft 22A are attached (see FIGS. 23, 24).
Specifically, the caulking member 30 is disposed such that the first open portion 36 matches the opening 103 of the inner support member 102b while the plate-like portion 33 is disposed to cover the upper side of the fixing portion 51 (screw 53). In this state, the pivot shaft 22A is inserted from the opening 103 of the outer support member 102a.

Then, by performing the insertion of the rotation shaft 22A over the entire length, as shown in FIG. 16, the attachment of the rotation shaft 22A and the related members is completed (see FIGS. 24 and 16).
FIG. 25 is a schematic view of a predetermined cross section (a cross section including A-A in FIG. 18) in a state in which attachment of the caulking member 30 and the related members is completed.
FIG. 26 is a perspective view of the medal selector as viewed from the lower left direction, and FIG. 27 is a perspective view of the medal selector as viewed from the lower right direction.

As shown in FIGS. 25 to 27, in a state in which attachment of the caulking member 30 and the related members is completed, the pivot shaft 22A is supported by the outer support member 102a and the inner support member 102b, and the pivot shaft 22A is used. The lever switch 17 is pivotally supported.
In this state, the pivot shaft 22A is fixed by the caulking member 30 (see the description of FIG. 21), which makes it difficult to remove it from the support member 102 as well.
Further, at this time, the plate-like portion 33 of the caulking member 30 is disposed at a position covering the upper portion of the region of the fixing portion 51 of the cover 50 (see FIGS. 23 and 16 in comparison).
This makes it possible to make external access to the fixing portion 51 and the screw 53 difficult, so that the detecting means a covered by the cover 50 can be protected more firmly.
For example, when trying to access the detection means a for the purpose of fraud, the cover 50 physically disturbs the detection means a, so that the detection means a can be protected from such unauthorized access.
On the other hand, after the cover 50 is removed, a fraudulent act of accessing the detecting means a may be considered.
However, even in this case, the caulking member 30 (the plate-like portion 33) is fixed in a state in which the fixing portion 51 of the cover 50 and the screw 53 cover the access difficult, so the cover 50 can not be removed easily.

As described above, in the gaming machine of the present embodiment, the pivot switch 22A of the lever switch 17 is difficult to remove, and the cover 50 for protecting the sensors is covered with the caulking mechanism that covers the cover in a difficult manner. The shape caulking member 30 is attached to the pivot shaft 22A.
For this reason, unauthorized access from the outside to important parts including the lever switch 17 and other sensors can be efficiently prevented by the caulking member 30 alone.

Further, the outer periphery of the shaft rear portion 223 of the pivot shaft 22A is accommodated in the cylindrical cover 104 (the outer peripheral member of the present invention) substantially without a gap (see FIGS. 25 and 26).
Thereby, for example, it is possible to prevent the removal of the pivot shaft 22A for the purpose of fraud.
For example, as shown by arrow aa in FIG. 25, even if a tool such as a driver is inserted into the gap between the pivot shaft 22A and the cylindrical cover 104, it can not be inserted because there is no gap.
At this time, since the periphery of the cylindrical cover 104 is easily damaged by the tool, it can be used as a trace (proof) to make it easy to detect a fraud.
Further, as shown by the arrow bb in FIG. 25, a tool is inserted into the gap between the lever switch 17 and the outer support member 102a, and the pivot shaft 22A is moved in the direction of the arrow cc in FIG. It is also conceivable to try to extract it.
However, in this case, since the outer support member 102a and the cylindrical cover 104 themselves are destroyed, they can be left as traces of unauthorized access.

Further, as shown by an arrow dd in FIG. 25 and FIG. 27, for example, a fraudulent act of inserting a tool from the second opening portion 37 of the caulking member 30 and pushing out the pivot shaft 22A may be considered.
On the other hand, the wall 52 of the cover 50 is arranged so as to shield the open portion (second open portion 37) communicating with the pivot shaft 22A in a state where the caulking member 30 is attached to the pivot shaft 22A. .
For this reason, it is possible to prevent a fraudulent act of inserting the tool from the second opening 37 and pushing out the pivot shaft 22A.

Further, as shown by arrow ee in FIG. 25 and FIG. 27, it is also conceivable to lift the second cylindrical portion 32 side for removing the caulking member 30 for the purpose of fraud.
However, the caulking member 30 has a portion b protruding from the tip end portion 225 of the rotation shaft 22A in a state of being attached to the rotation shaft 22A, and a predetermined position (a position near the tip portion 225) of the protruding portion b. In the above, the thin groove portion 34 is formed in a thin groove shape.
For this reason, by applying a certain or more force in the direction of the arrow ee, the member is sheared along the thin-walled groove portion 34, and as a result, it is possible to leave a trace of fraud due to this damage.

On the other hand, in the conventional gaming machine, there is provided a detection means capable of detecting passage of medals by displacement of the rotation member, and covering this detection means with a cover makes it difficult to access the detection means. There is no gaming machine provided with a member that makes it difficult to remove both the pivot shaft and the cover that pivotally support the pivot member (see, for example, Patent Document 1).
Also, although there is a dedicated member as a fastener for the pivot shaft, even if it is attempted to adopt such a dedicated member, such a single application is used in a device in which many parts are integrated, such as a medal selector. There is a problem that there is not enough space for providing a dedicated member for the
According to the gaming machine of the present embodiment, it is possible to solve all or part of such a problem that the conventional gaming machine should improve.

  The preferred embodiment of the gaming machine according to the present invention has been described above, but the gaming machine according to the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. Needless to say.

For example, although the configuration in which the caulking member 30 is attached to the pivot shaft 22A that pivotally supports the pivot member (lever switch 17) used for the sensor of the medal selector has been described in the present embodiment, the caulking member 30 is limited to the medal selector or sensor Instead, it can be attached to a pivot used in various applications and devices.
Moreover, although the caulking member 30 demonstrated the structure which the part of the plate-like-part 33 covers the area | region of the fixing | fixed part 51 of the cover 50, not only this but the structure which covers a sensor or a cover may be sufficient.
Moreover, although applied to the slot machine in this embodiment, when a rotation member is used as a component of a pachinko machine, it can also be applied to a pachinko machine.
