Description

  The present invention includes a storage tank that stores game balls supplied from the outside, and a discharge device that is provided integrally with the storage tank and that can discharge game balls stored in the storage tank to the downstream side. Related to gaming machines.

  A conventional gaming machine is composed of a gaming board that forms a gaming area and a front frame (main body frame) to which the gaming board is attached. The front frame is formed with a game board storage part for storing the game board, and the game board is stored in the game board storage part so that the game area faces the front side from the front side or the rear side of the game machine. In addition, on the back side of the front frame, there are provided a discharge device that discharges prize balls and rental balls, a discharge control device that controls the discharge device, various ball passages, and the like. The game board is provided with an electrical device such as a liquid crystal display device, and the electrical device is disposed in a bulging state on the rear side of the game board. Therefore, on the back side of the front frame, the discharge device, the spherical flow path, and the like are arranged so as to avoid this electrical device. In recent years, with the increase in the size of electrical devices arranged on game boards, particularly liquid crystal display devices, there has been a tendency to increase the problem of arrangement space of various mechanisms on the back side of the front frame.

  In addition, a storage tank for temporarily storing game balls supplied from the island facility is provided at the upper part on the back side of the front frame. A lead-out basket is provided on the downstream side of the storage tank, and the game balls stored in the storage tank flow down the lead-off basket and are rectified into one row while being rectified in one row (on the axis attachment side of the front frame) ). A spherical channel is formed in the vertical direction on one side of the back side of the front frame. The upstream end of this spherical channel is connected to the downstream end of the outlet so that the outlet can flow down. The game ball is to change the flow direction in the vertical direction near the side edge of the front frame. The discharge device is provided in the middle of the ball flow path, and a predetermined number of game balls are discharged by the discharge device.

In addition, a gaming machine in which the discharge device is not provided in the middle of the flow path in the vertical direction but is provided integrally with a storage tank is also considered (see, for example, Patent Document 1).
When the discharge device is provided integrally with the storage tank, since the discharge device is removed on one side of the back surface side of the front frame, only the spherical flow path is provided. Even if the empty space on the rear side of the game board becomes large and the electrical equipment of the game board as described above increases in size, the back mechanism of the main body frame (such as the discharge device and the ball channel) interferes with the electrical equipment. There is an effect that can be prevented.
JP-A-8-141175

  However, in the conventional discharge device, the game balls stored in the storage tank are directly received by the discharge device, that is, the game balls are received without aligning the game balls with the lead-out rod. There is a possibility that a game ball cannot be received in each of the holding holes. When such a situation occurs, there is a problem that smooth discharge (continuous discharge) cannot be performed.

  Furthermore, in order to perform quicker discharge, it is necessary to increase the rotation speed of the rotating body. However, if the rotation speed is high, it becomes increasingly difficult to reliably receive the game ball in each holding hole. In addition to increasing the possibility of a mistake in receiving into the holding hole, when the game ball in the holding hole is dropped to the payout port, the amount of fall of the game ball from the holding hole is reduced. There is also a possibility that the amount of rotational movement becomes too large, and the game ball is sandwiched between the holding hole of the rotating body and the payout port, making it impossible to discharge.

  An object of the present invention is to provide a game machine that is provided integrally with a storage tank and that can discharge game balls stored in the storage tank to the downstream side. In addition to being able to do so, it is possible to quickly discharge the game balls.

In order to solve the above problems, the invention according to claim 1 is a storage tank that stores game balls supplied from the outside, and a game ball that is provided integrally with the storage tank and stored in the storage tank. In a gaming machine equipped with a discharge device capable of discharging the
The discharging device is
A sprocket that is configured to be rotatable about a rotation axis set in the vertical direction and has a plurality of ball receiving recesses for receiving game balls;
A storage unit that stores the sprocket and that is formed with an outlet for discharging the game ball from the ball receiving recess to the downstream side at the bottom,
With
The sprocket is configured to receive a plurality of game balls in each ball receiving recess in the vertical direction, and by rotating the sprocket, the game ball is received at the top of the ball receiving recess and the lowest game ball is received. Configured to derive,
The outlet is formed within the range of the movement trajectory of the game ball received in the ball receiving recess at the bottom, and a gap is formed between the lower surface of the sprocket and the upper surface of the bottom. Placed in
The outlet is
A discharge outlet with a detection sensor for detecting the discharge ball;
A ball outlet for extracting the game ball of the storage tank to the outside of the game machine,
Above the range from the discharge outlet to the ball outlet in the side wall of the storage portion, a game ball that is one level higher than the lowest stage in the ball receiving recess is the drain outlet and the ball outlet guide. A rib for preventing the flow from flowing down to the outlet protrudes toward the center of the sprocket,
By changing the rotation direction of the sprocket, the game ball in the ball receiving recess is led out from either the discharge outlet or the ball outlet .

Here, the “outlet” is, for example, an outlet for extracting a game ball from a storage tank, or an outlet for discharging a game ball as a prize ball or a rental ball.
In addition, the “gap” is not a minute gap that secures the operation of the sprocket, but a gap that can smoothly guide the game ball to the outlet, or a ball gap when guiding the game ball to the outlet. It is a gap which can prevent.

According to the first aspect of the present invention, since the discharge device is provided integrally with the storage tank, it is possible to reduce the installation space compared to the case where these are installed separately, and the space problem on the back side of the gaming machine Can be eliminated.
In addition, by setting the rotation axis of the sprocket having the ball receiving recess in the vertical direction and arranging the sprocket horizontally, the ball receiving recess is arranged along the vertical direction, and the game ball in the storage tank Alternatively, the game balls flowing down from the storage tank can be smoothly discharged downward.

In addition, since the sprocket is configured so that a plurality of game balls can be received in the vertical direction in each ball receiving recess, the game ball is received at the top of the ball receiving recess and the lowest game ball is derived. Even if an acceptance mistake occurs in the ball receiving recess, the already received game ball can be discharged, and continuous discharge becomes possible. Therefore, even if the sprocket is rotated at a high speed, a discharge error can be prevented.
Further, since a gap is formed between the lower surface of the sprocket and the upper surface of the bottom portion, a game ball is not caught between the sprocket and the outlet, and ball clogging due to high-speed rotation of the sprocket can be prevented. . That is, the game balls can be discharged at high speed synergistically by the above two functions.
In addition, the outlet port includes a discharge outlet port and a ball outlet outlet port. By changing the sprocket rotation direction, the outlet port is derived from either the outlet outlet port or the ball outlet outlet port. The outlet for deriving the game ball can be switched by changing the rotation direction of the sprocket.
That is, if the sprocket is rotated in one direction (for example, clockwise), the game ball is derived from the discharge outlet, and if it is rotated in the other direction (for example, counterclockwise), it is A game ball can be derived, and it is possible to efficiently switch between discharging and ball removal by switching the rotation direction of the sprocket.
In addition, a rib that prevents the game ball that is one step higher than the lowest step in the ball receiving recess from flowing down to the lead-out port above the range from the discharge lead-out port to the ball discharge lead-out port on the side wall of the storage unit. Since the protrusions are provided, it is possible to prevent a plurality of game balls from continuously falling from the same ball receiving recess to the outlet.

The invention according to claim 2 is the gaming machine according to claim 1 , wherein the ball receiving recess of the sprocket is
An upper first ball receiving recess for receiving a game ball from an introduction portion for receiving the game ball of the storage tank;
A second ball receiver that is arranged below the first ball receiving recess and on a circumference smaller in diameter than the circumference where the first ball receiving recess is arranged, and leads the game ball to the outlet. A recess,
An inclined surface which is set and provided with a predetermined vertical dimension between the first sphere receiving recess and the second sphere receiving recess, and is continuous from the inner surface of the first sphere receiving recess to the inner surface of the second sphere receiving recess. An intermediate ball receiving recess having
Including
The protruding amount of the projecting portion constituting the second ball receiving recess is set smaller than the projecting amount of the projecting portion that is provided on the outer peripheral portion of the sprocket so as to project outward and configure the first ball receiving recess. And

According to the invention described in claim 2 , the ball receiving recess includes an upper first ball receiving recess that receives the game ball, and a circumference in which the first ball receiving recess is arranged below the first ball receiving recess. Are arranged on a circle having a diameter smaller than the diameter of the second ball receiving recess for guiding the game ball to the outlet, and provided between the first ball receiving recess and the second ball receiving recess with a predetermined vertical dimension. The intermediate sphere receiving recess having an inclined surface that continues from the inner side surface of the first sphere receiving recess to the inner side surface of the second sphere receiving recess can smoothly rotate the sprocket.

In other words, the diameter of the circumference in which the respective ball receiving recesses are arranged is such that the first ball receiving recess is the largest, and the intermediate ball receiving recess and the second ball receiving recess are formed in this order so as to become smaller. In the game balls that overlap in the vertical direction, the game ball that overlaps the upper side overlaps the outside along the radial direction of the sprocket rather than the lower game ball. As a result, the pressure in the vertical direction due to the load of the upper game ball on the lower game ball is reduced.
Since the game ball received in the intermediate ball receiving recess comes into contact with the inclined surface of the sprocket, the pressure due to the load of the game ball received in the first ball receiving recess is dispersed here, and the center axis of the sprocket applied to the sprocket The pressure in the direction will be reduced.
Therefore, even if a plurality of game balls are received around the sprocket, the sprocket can be smoothly rotated.

  Each ball receiving recess accepts three game balls so as to overlap each other, so that even if there is a mistake in receiving a game ball, the game ball will be replenished until the stage where the mistake occurs is the lowest level. Therefore, it is possible to prevent the discharge from being interrupted.

In addition, since the projecting amount of the projecting portion that constitutes the second ball receiving recess is set smaller than the projecting amount of the projecting portion that is provided on the outer periphery of the sprocket so as to project outward and configure the first ball receiving recess, the storage tank The shape of the first ball receiving recess facing the introduction portion for receiving the game ball can be set so as to surround a wide range (for example, approximately a half circumference) of the game ball, and the game ball can be reliably received.
That is, when the protruding amount of the protruding portion of the ball receiving recess is small, there is no protruding portion between adjacent game balls, so the receiving area of the game ball becomes the game ball on both sides. If there is, the receiving area changes due to the movement of the game ball, and furthermore, since there is no member between the game ball and the game ball, the unevenness on the upper surface of the sprocket will increase, and the game ball will jump greatly Although this hinders the acceptance of the ball, such a problem can be solved.
On the other hand, by setting the projection amount of the projecting portion constituting the second ball receiving recess small, it is possible to reduce the contact portion with the game ball at the time of deriving to the outlet, and the ball receiving recess and the outlet Ball clogging can be prevented.

  Invention of Claim 3 is a gaming machine of Claim 1 or Claim 2, Comprising: It exists in the range of the movement locus | trajectory of the game ball received in the said ball | bowl receiving recessed part in the said bottom part, and the said A projecting portion is formed between the discharge outlet and the ball outlet outlet at a position below the rib in a portion where the rib is provided.

According to the present invention, since the discharge device is provided integrally with the storage tank, the space for installing these can be reduced, and the space problem on the back side of the gaming machine can be solved.
In addition, by setting the rotation axis of the sprocket having the ball receiving recess in the vertical direction and arranging the sprocket horizontally, the ball receiving recess is arranged along the vertical direction, and the game ball in the storage tank Alternatively, the game ball flowing down from the storage tank can be smoothly discharged downward.
In addition, since the sprocket is configured to receive a plurality of game balls in each ball receiving recess in the vertical direction, the game ball is received at the top of the ball receiving recess and the lowest game ball is derived. Even if an acceptance mistake occurs in the ball receiving recess, the already received game ball can be discharged, and continuous discharge becomes possible.
Further, since the gap is formed between the lower surface of the sprocket and the upper surface of the bottom, it is possible to prevent clogging of the balls due to the high speed rotation of the sprocket. That is, the game balls can be discharged at high speed synergistically by the above two functions.
In addition, the outlet port includes a discharge outlet port and a ball outlet outlet port. By changing the sprocket rotation direction, the outlet port is derived from either the outlet outlet port or the ball outlet outlet port. The outlet for deriving the game ball can be switched by changing the rotation direction of the sprocket.
That is, if the sprocket is rotated in one direction (for example, clockwise), the game ball is derived from the discharge outlet, and if it is rotated in the other direction (for example, counterclockwise), it is A game ball can be derived, and it is possible to efficiently switch between discharging and ball removal by switching the rotation direction of the sprocket.
In addition, a rib that prevents the game ball that is one step higher than the lowest step in the ball receiving recess from flowing down to the lead-out port above the range from the discharge lead-out port to the ball discharge lead-out port on the side wall of the storage unit. Since the protrusions are provided, it is possible to prevent a plurality of game balls from continuously falling from the same ball receiving recess to the outlet.

Thereby, the storage tank 220 integrated with the discharge device 200 is positioned and fixed to the back surface component 160.

  As shown in FIGS. 5 and 6, the storage tank 220 and the discharge device 200 that are integrally formed have a cylindrical body portion 201 that serves as a housing (main body 203 described later) of the storage tank 220 and the discharge device 200. Are integrally formed, a stepping motor 204 as a drive source of the discharge device 200, a drive source mounting member 206 for attaching the stepping motor 204 to the integral molding portion 223, and a game in the storage tank 220 A sprocket 210 as a rotating body having a plurality of (for example, about 10) ball receiving recesses 208 for receiving and moving the balls to the discharge outlet 20a or the ball outlet outlet 20b; The rotating body upper member 214 disposed on the center portion and the game ball in the discharge device 200 (in the storage portion 203) are supported from below. A disk-shaped bottom portion 216, a bottom member 218 that is fixed to the lower end portion of the cylindrical portion 201 and supports the bottom portion 216, supports a discharge ball detection sensor 217 that detects a discharged game ball, and a storage tank A height restricting member 260 for restricting the height of the game balls stacked from the bottom wall 22a (introducing portion 202) is provided on a portion 220 of the discharge device 200.

As shown in FIGS. 5 to 12, the integrally molded portion 223 corresponds to a storage tank 220 extending in the left-right direction and a discharge device 200 formed on one end side in the left-right direction of the storage tank 220. The cylindrical portion 201 is opened to the lower side.
And the storage tank 220 comprises the bottom of the storage tank 220 extended to right and left, and the left and right which inclines downward from the other edge part side of the left-right direction toward the one edge part side in which the discharge apparatus 200 is provided. A long bottom wall 22a having a substantially rectangular shape, a right side wall 22b standing substantially vertically from the right edge when viewed from the front of the bottom wall 22a, and a front side standing substantially vertically from the front edge of the bottom wall 22a A wall 22c, a rear wall 22d erected substantially vertically from the rear edge of the bottom wall 22a, and an arc plate erected substantially vertically from the left arc-shaped side edge as viewed from the front of the bottom wall 22a Left side wall 22e.

  As shown in FIG. 12, the bottom wall 22a is disposed so as to be inclined downward from right to left as viewed from the front, and further, as shown in FIGS. 14B and 14C, It slopes down from the front towards the front. Note that the inclination of the bottom wall 22a from right to left causes the game ball stored in the storage tank 220 to flow from the other end to the one end where the discharging device 200 is provided on the upper surface of the bottom wall 22a. It is for forming the inclined part 22h for making it. As a result, the inclined portion h on the bottom wall 22a has a width within the front and rear that is equivalent to a plurality of game balls (for example, about 5 to 10 times the diameter of the game ball) on the bottom wall 22a due to the inclination from right to left. Thus, a plurality of game balls can flow down toward the discharge device 200. Note that the inclined portion 22h is not a game flow channel but a bottom portion of the storage tank 220 in which game balls are stacked one above the other, so the game balls do not necessarily flow linearly, but flow irregularly. That is, the bottom wall 22a of the storage tank 220 is inclined downward toward one side in the left-right direction of the gaming machine 100, and an inclined portion 22h in which game balls flow irregularly with a plurality of widths is formed.

  Further, the downward inclination from the rear side toward the front side of the bottom wall 22a is along the forward rotation direction of the sprocket 210 as will be described later. In addition, the inclination of the bottom wall 22a is basically described later in the left end portion where the discharge device 200 is provided in both the long side direction (downward inclination from right to left) and the short side direction (downward inclination from rear to front). The annular guide portion 22g, which is the front end (right side) of the annular guide portion 22g, is the end of the bottom wall 22a on the discharge device 200 side, and is inclined downward from the outer peripheral side toward the center side. It has become. Accordingly, the inclined portion 22h of the bottom wall 22a extends to the front of the guiding portion 22g.

The sprocket 210 is arranged inside the guide portion 22g. The forward rotation direction of the sprocket 210 is clockwise (clockwise), and the inclined portion of the bottom wall 22a on the right side of the sprocket 210 is provided. In 22h, the rotation direction of the sprocket 210 is from the rear side to the front side. Therefore, the game ball is guided in the rotational direction of the sprocket 210 by tilting the bottom wall 22a downward and forward from the rear.
That is, the bottom wall 22a of the storage tank 220 is formed with an inclined portion 22h that is inclined downward to one side in the left-right direction of the gaming machine 100, and a guiding portion 22g that is inclined downstream of the inclined portion 22h. Corresponding to the rotation direction of the sprocket 210, the game machine 100 is inclined downward toward the one side in the front-rear direction. The entire inclined portion 22h inclined from right to left does not need to be inclined downward from the rear to the front, and only the left side of the inclined portion 22h (discharge device 200 side) may be inclined downward from the rear to the front. .

Further, as shown in FIGS. 7, 8, and 14C, the bottom wall 22a is formed with a guide step 22i that is higher on the rear side and lower on the front side at the left end when viewed from the front of the inclined portion 22h. Has been. The guide step 22i is formed obliquely toward the front side toward the left side (the discharge device 200 side). The step of the guide step 22i is substantially the left and right of the rear edge of the bottom wall 22a. It is formed along a line segment from the central portion toward the approximate center of the annular ring of the annular guiding portion 22g.
That is, a guide step portion 22 i that guides a game ball flowing down to the guide portion 22 g to one side in the front-rear direction of the gaming machine 100 is provided on the inclined portion 22 h corresponding to the rotational direction of the sprocket 210. The guide step 22i is also for guiding the flow of the game ball in the storage tank 220 so as to follow the forward rotation of the sprocket 210.

  Further, the bottom wall 22a is formed in an arc shape in which the side edge on the left end side where the discharge device 200 is disposed is a substantially semicircular shape, and further, the left end portion of the arc shaped bottom wall 22a has an arc shape. The above-described cylindrical cylindrical portion 201 is disposed on the lower surface side of the bottom wall 22a so as to be concentric with the center of the circle, with the axial direction being up and down. A circular opening 22f having an outer periphery along the inner periphery of the cylindrical portion 201 is formed at a portion where the upper end of the cylindrical portion 201 of the bottom wall 22a and the bottom wall 22a are joined.

  In other words, an opening 22f having a smaller diameter than the circle is formed on the end of the bottom wall 22a on the side of the discharge device 200 where the side edge of the bottom wall 22a has an arc shape. Yes. In addition, an annular guide portion 22g having a width that is an interval between the opening portion 22f and the arc-shaped side edge is formed outside the periphery of the opening portion 22f. In addition, the (outer circumference) diameter of the guide portion 22g is equal to the interval between the front wall 22c and the rear wall 22d of the storage tank 220 (for example, the front-rear width of the inclined portion 22h), and the gaming machine 100 inside the storage tank 220 A guiding portion 22g is formed over the entire width along the front-rear direction. That is, the length of the inclined portion 22h in the front-rear direction of the gaming machine 100 and the length of the outer diameter of the guide portion 22g are configured to be substantially the same. As will be described later, when the guide portion 22g is also included in the introduction portion 202, the introduction portion 202 is also formed over the entire width along the front-rear direction of the gaming machine 100 inside the storage tank 220. .

The guide portion 22g is inclined downward from the outer peripheral portion toward the center as described above, and guides the game ball to fall into the opening portion 22f. Note that the opening 22f, disposed sprocket 210 is, at a position immediately facing inward of the guiding portion 22 g, spherical receiving recess 208 in a state aligned along the outer periphery of the sprocket 210 in the circumferential direction, ... is formed The guiding portion 22g guides the game ball to the ball receiving recesses 208,... In the opening 22f. Further, the above-described ball receiving recesses 208,... Are arranged at an annular interval from the inner peripheral side of the guiding portion 22g to the rotation guiding portion 21f described later, and this interval is the ball receiving recess 208,. The game ball that is received in the storage unit 220 is introduced into the discharge device 200 from the storage tank 220.

Therefore, due to the relationship between the guide portion 22g and the inclined portion 22h, the introduction portion 202 is formed on the inclined downstream side of the inclined portion 22h.
In addition, the width (difference between the outer diameter and the inner diameter) between the outer circumference and the inner circumference of the guide portion 22g corresponds to the diameter of the game ball. For example, the width is equal to or greater than the diameter of the game ball. It is supposed to be 2 times or less. In addition, the outer peripheral portion that is the highest position in the guide portion 22g is lower than the end portion on the discharge device 200 side that is the lowest position of the inclined portion 22h that is inclined downward toward the discharge device 200 side of the bottom wall 22a. A step having a steep inclination is formed between the inclined portion 22h and the guiding portion 22g.

  That is, the guide portion 22g that surrounds the outer periphery of the sprocket 210 and is formed in a circle with a width of approximately one game ball and that is inclined downward toward the sprocket 210 and guides the game ball to the ball receiving recesses 208,. 22a.

A front wall 22c is joined to the front edge side of the right side wall 22b, and a rear wall 22d is joined to the rear edge side so as to surround the front and rear and the right side, and the bottom wall is closed below. The upper side edges of the right side wall 22b, the front wall 22c, and the rear wall 22d are arranged flush with each other in a substantially horizontal plane. Therefore, the front wall 22c and the rear wall 22d are in a state where the upper edge is horizontal and the lower edge is inclined in the same manner as the bottom wall 22a. Accordingly, the storage tank 220 has a depth that increases from the other end toward the one end on the discharge device 200 side when only the portion that becomes the inclined portion 22h of the bottom wall 22a is viewed. It is configured.
Note that the height of the end portions of the front wall 22c and the rear wall 22d on the discharge device 200 side is lowered by one step. And the height of the said edge part of the front wall 22c and the rear wall 22d is about 1/2 or less of the height of the part near the level | step difference before a level | step difference.

Also, the front edge of the arc-shaped left side wall 22e is joined to the front wall 22c, and the rear edge is joined to the rear wall 22d. The height of the left side wall 22e is the level difference between the front wall 22c and the rear wall 22d. The height on the lower side is the same. Note that the upper edge of the semicircular arc plate-like left side wall 22e and the lower edge of the front wall 22c and the rear wall 22d on the lower step side are arranged in a substantially horizontal plane (arranged flush with each other).
As described above, the diameter of the guide portion 22g is made substantially equal to the distance between the front wall 22c and the rear wall 22d, and the diameter of the arc plate-like left side wall 22e is made substantially equal to the diameter of the guide portion 22g. And the left side wall 22e is arrange | positioned so that the one side half of the guidance | induction part 22g may be enclosed along the outer periphery of the one side (left side) of the outer periphery of the guidance | induction part 22g. That is, the (left) side wall 22e on the guide portion 22g side of the storage tank 220 is formed in a semicircular shape along the outer periphery of the guide portion 22g.

  As a result, the semicircular portion opposite to the inclined portion 22h of the guiding portion 22g is surrounded by the left side wall 22e, so that the game ball flowing down the inclined portion 22h may flow down to the opposite side beyond the guiding portion 22g. The game ball can be securely guided to the introduction unit 202 (ball receiving recess 208,...) By holding the game ball inside the guide unit 22g. Further, since a space such as a corner is not formed on the opposite side of the inclined portion 22h of the guiding portion 22g, when the game ball that has flowed down the inclined portion 22h stays at the corner around the guiding portion 22g and the ball is removed. In addition, it is possible to prevent the game ball from remaining in the storage tank 220.

The bottom wall 22a, the right side wall 22b, the front wall 22c, the rear wall 22d, and the left side wall 22e described above form a substantially rectangular box (the left side is an arcuate surface) having an open top surface. It becomes the storage tank 220.
As shown in FIGS. 7, 8, 9, 12, 13, and 14, the cylindrical portion 201 has an inner periphery that is substantially the same diameter as the opening portion 22 f of the bottom wall 22 a and stores the sprocket 210. 203 main body. The cylindrical body portion 201 includes a cylindrical first cylindrical body 21a that is an upper portion of the cylindrical body portion 201 connected to the bottom wall 22a, and a lower portion of the cylindrical body portion 201 that has an inner diameter that is larger than that of the first cylindrical body 21a. The second cylindrical body 21b, which is smaller than the first cylindrical body 21b, is disposed between the first cylindrical body 21a and the second cylindrical body 21b, and is disposed in a state in which the first cylindrical body 21a and the second cylindrical body 21b are connected. It has an intermediate cylinder 21c.

  The 1st cylinder 21a is formed in the cylindrical shape of the same diameter over the up-down direction. As described above, the second cylinder 21b has a smaller diameter than the first cylinder 21a and is formed in a cylindrical shape having the same diameter in the upward direction. However, the second cylinder 21b is provided on the bottom 216 having the discharge outlet 20a. A notch 21d is formed in a portion corresponding to a later-described lead-out convex portion 21i. The intermediate cylinder 21c has an upper end formed continuously with the first cylinder 21a and the same diameter as the first cylinder 21a, and a lower end formed continuously with the second cylinder 21b. It has the same diameter as the two cylinders 21b and is formed in a cylindrical shape and a truncated cone shape so that the diameter decreases from the upper end toward the lower end. Therefore, the inner peripheral surface of the intermediate cylinder 21c is an inclined surface that is inclined downward from the outside to the inside.

Further, at the boundary between the second cylinder 21b and the intermediate cylinder 21c and above the range from the discharge outlet 20a to the ball outlet outlet 20b formed on the bottom 216, there is a cylinder. Ribs 21e are formed along the inner circumference protruding toward the center side of the body part 201 (center direction of the sprocket 210). This is when the lowest game ball of the game balls received in the upper and lower stages in the ball receiving recesses 208, ... is led downward from the discharge lead-out part 20a or the ball discharge lead-out part 20b. The ribs 21e prevent the game balls from being led out together. That is, as will be described later, the game ball arranged between the outer peripheral portion of the sprocket 210 and the inner peripheral surface of the cylindrical portion 201 does not have much play, so that it cannot flow downward by the slightly protruding rib 21e. .
That is, in the required range above the outlets (the discharge outlet 20a and the ball outlet outlet 20b) in the side wall (cylinder body 201) of the storage part 203, it is one level higher than the lowest level in the ball receiving recesses 208,. A rib 21e for preventing the upper game ball from flowing down to the discharge lead-out portion 20a and the ball discharge lead-out portion 20b (to hold the game ball in the ball receiving recess 208,...) In the center direction of the sprocket 210. It is protruding.

Further, as described later, when the sprocket 210 rotates in the forward direction, the game ball is derived from the discharge derivation unit 20a, and when rotated in the reverse direction, the game ball is derived from the ball removal derivation unit 20b. When the sprocket 210 rotates in the direction, the game ball is not led out from both the discharge lead-out portion 20a and the ball discharge lead-out portion 20b. This is because the rib 21e is formed over a range from the discharge lead-out portion 20a to the ball discharge lead-out portion 20b. That is, for example, the sprocket 210 rotates forward, and the lowermost game ball of the ball receiving recess 208 is led out at the discharge lead-out portion 20a. At this time, the game ball above it is lowered by the rib 21e. Movement to is restricted.
As a result, there is no game ball in the lowermost portion of the ball receiving recess 208. In this state, when the ball receiving recess 208 moves from the discharge lead-out portion 20a to the ball discharge lead-out portion 20b, the game ball above the bottom is still restricted from moving downward by the rib 21e. Therefore, there is no game ball at the bottom of the ball receiving recesses 208,...

Then, when the ball receiving recesses 208,... Pass through the part of the ball removal lead-out portion 20b, the ball receiving recesses 208b are separated from the rib 21e, and the second and subsequent game balls move downward one step from the bottom in the ball receiving recesses 208,. When the game ball is arranged at the bottom and again moves to the discharge derivation unit 20a, the game ball can be derived. In addition, there is no game ball in the uppermost step of the ball receiving recesses 208,.
In addition, when the sprocket 210 is rotated in the reverse direction, the discharge derivation unit 20a and the ball extraction derivation unit 20b are switched, and the game ball is derived from the ball extraction derivation unit 20b, and the discharge derivation unit The game ball is not derived from 20a.

  A half-end sensor 22k is disposed on the front side of the lower portion of the storage tank 220 and on the front side of the discharge device 200 side. This half-end sensor 22k basically does not reach the number of discharges at one time when the remaining amount of game balls in the storage tank 220 is less than the maximum number of game balls to be paid out at one time. This prevents the odd number of game balls from being paid out. The half-end sensor 22k prevents the discharge device 200 from operating even when there is no game ball in the storage tank 220. The half-end sensor 22k is composed of a sensor that detects a game ball, such as a proximity sensor that detects the game ball in a non-contact manner, and the signal for detecting the game ball from the half-end sensor 22k is interrupted (no game ball is detected). Until the signal indicating that the game ball is supplied from the island facility side and the game ball is detected from the half-end sensor 22k is input. Control to stop the discharge of the ball.

  Further, the supply of game balls to the storage tank 220 is controlled by a game ball supply device provided in the island facility, and a sensor for detecting the amount of game balls stored in the storage tank 220 is: For example, when the gaming machine 100 is installed, it is set corresponding to the storage tank 220 when connected to the game ball supply device side.

  In the storage tank 220, among the walls surrounding the bottom wall 22a, the discharge device 200 side end portion and the left side wall 22e of the front wall 22c and the rear wall 22d are lowered as described above. If the game balls are replenished so that the tank 220 is almost full, the game balls overflow from the end of the storage tank 220 on the discharge device 200 side. On the other hand, the driving ball mounting member 206 for fixing the stepping motor 204 serving as the drive source of the discharge device 200 to the storage tank 220 is a game ball from the end of the discharge device 200 where the height of the storage tank 220 is lowered. Acts as a lid to prevent leakage.

The drive source mounting member 206 has a shape obtained by extending a semi-circular plate body with a thin plate having a width of the semi-circular diameter, and the semi-circular portion is disposed on the semi-circular left side wall 22e. The extended thin plate portion is disposed on the lowered end portions of the front wall 22c and the rear wall 22d.
The drive source mounting member 206 is an end on the discharge device 200 side that is one step lower among the walls (the right side wall 22b, the front wall 22c, the rear wall 22d, and the left side wall 22e) surrounding the bottom wall of the storage tank 220. The part is blocked.

Further, a step of the front wall 22c is formed on a side edge of the drive source mounting member 206 that is in contact with the stepped portions of the front wall 22c and the rear wall 22d, that is, a side edge opposite to the arcuate side edge. In addition, a dam wall 207 erected up and down along the step of the rear wall 22d is attached.
The dam wall 207 prevents the game ball from flowing out from the stepped portion of the front wall 22c and the rear wall 22d to the drive source mounting member 206 side. In this example, the height restricting member 260 is disposed on the right side (the other end side) of the dam wall 207, and the height restricting member 260 dams the game ball, so the dam wall 207 dams the game ball. Although it is not necessary, if the game ball repels and rests on the height limiting member 260, the game ball can be prevented from falling.

Further, the dam wall 207 is provided on the drive source mounting member 206, thereby functioning as a reinforcement member of the drive source mounting member 206 and function as a reinforcement member for joining the drive source mounting member 206 and the storage tank 220. Have
Further, the drive source mounting member 206 has a flat bottom surface, and a reinforcing rib, a mounting member for the stepping motor 204, and the like are formed on the top surface side. Further, a through-hole penetrating the rotation shaft of the stepping motor 204 is formed at the center of the circle of the semicircular portion of the drive source mounting member 206.
That is, the drive source mounting member 206 is configured to support the stepping motor 204 on the upper side thereof.

Further, the side edge portion of the drive source mounting member 206 on the side where the dam wall 207 is provided, that is, the side edge portion facing the end side opposite to the end portion where the discharge device 200 of the storage tank 220 is provided. As will be described later, an attachment portion 261 of the height limiting member 260 is attached.
Further, the drive source mounting member 206 is formed with a fixed piece 20x projecting outward at a plurality of positions on the outer peripheral portion with a space between each other. Then, the fixed piece 20x is screwed to the boss 20y formed so as to protrude from the end of the front wall 22c and the rear wall 22d, which are lowered by the step, and the left side wall 22e so as to be outside the storage tank 220. By being stopped, the drive source mounting member 206 is fixed to the storage tank 220.

As shown in FIGS. 12 to 14, at the side edge of the drive source mounting member 206 on the side of the dam wall 207, a height that limits the stacking height of game balls flowing down the inclined portion 22 h and flowing into the introduction portion 202. The restriction member 260 is provided over the entire width of the storage tank 220 in the front-rear direction of the gaming machine 100.
The height restriction member 260 includes an attachment portion 261 attached to the drive source attachment member 206, an extension portion 262 extending obliquely upward toward the upstream side of the inclined portion of the attachment portion 261, and the extension portion. It has a curved portion 263 that curves from the distal end portion of 262 and extends upward.
Note that the attachment portion 261, the extension portion 262, and the bending portion 263 are not necessarily separated from each other by a clear boundary, and each comb tooth portion of the height limiting member 260 that is formed into a comb tooth shape as described later. 264,... Are integrally formed with a mounting portion 261, an extending portion 262, and a bending portion 263.

Further, as shown in FIGS. 5 and 14, slits are provided at intervals from each other in the front-rear direction along the inclination in the left-right direction of the inclined portion (the left-right direction of the gaming machine) from the attachment portion 261 to the tip of the bending portion 263. (Notch) is formed, so that the height restricting member 260 is separated from the curved portion 263 and the extending portion 262 completely at each comb tooth portion 264... By the notches 265. It has a comb-like shape.
Further, the gap between the notches 265,... In the longitudinal direction of the gaming machine 100 or the width of the comb teeth portions 264,... In the longitudinal direction of the gaming machine 100 is substantially equal to the diameter of the gaming ball.
The height restricting member 260 is made of a synthetic resin having elasticity, and can be bent by being elastically deformed for each comb tooth portion 264... When an external force is applied.

That is, the height restricting member 260 is attached to the storage tank 220 on the inclined downstream side of the inclined portion 22h, and extends extending obliquely upward from the attached portion 261 to the inclined upstream side of the inclined portion 22h. It is formed in a comb-teeth shape including a mounting portion 262 and a bending portion 263 that curves upward from the extending portion 262 and is cut out from the mounting portion 261 to the distal end of the bending portion 263. The comb teeth 264,... Are configured to bend by the pressure of the game ball flowing down the inclined portion 22h.
Further, the height limiting member 260 is provided with notches (notches 265,...) Corresponding to the approximate diameter of the game ball.

When the game balls are stored on the inclined portion 22h in the storage tank 220 so as to be stacked higher than the lower surface of the drive source mounting member 206 by the height limiting member 260, the curved portion of the height limiting member 260 is mainly used. 263 dams up and guides the game ball above the extended portion 262 at substantially the same height as the drive source mounting member 206, and the extended portion 262 is disposed on the discharge device 200 side from the curved portion 263. Thus, the height at which the game balls are stacked is set to be lower than the extending portion 262, and the height at which the game balls are stacked gradually decreases toward the attachment portion 261.
At this time, the height restricting member 260 is elastically deformed for each comb tooth portion 264,... And the upper side is restricted by the height restricting member 260 and the stacked game balls are engaged with each other to form a bridge. Can be prevented.

Further, the game balls stacked on the sprocket 210 and the rotating member upper member 214 which are the rotating bodies exposed on the inner peripheral side (introducing portion 202) of the guiding portion 22g by the height limiting member 260 and the drive source mounting member 206. The height is limited to prevent clogging of the ball at the portion where the drive source mounting member 206 is provided, and the influence of the ball pressure based on the load of the game ball on the rotation of the sprocket 210 and the rotating body upper member 214 Is limiting.
As described above, since the mounting portion 261 of the height limiting member 260 is attached to the drive source mounting member 206, vibration during operation of the stepping motor 204 is caused to the height limiting member 260 via the drive source mounting member 206. Therefore, when the ball is bitten and a bridge is formed, the bridge can be broken by the vibration, and the clogging of the ball can be reliably prevented.

Further, the side edge of the drive source mounting member 206 on the side of the dam wall 207 opposite to the left side wall 22e is slightly inclined 22h from the rotation center of the sprocket 210, and is attached to this side edge. The mounting portion 261 of the height limiting member 260 is disposed on the sprocket 210 which is a rotating body except for the front end portion and the rear end portion. That is, a part of the attachment portion 261 is located immediately above the sprocket 210.
And since the attachment part 261 attached to the drive source attachment member 206 is in a state where it hardly bends, it cannot be expected that the ball clogging is released due to the bending, but the rotational force of the sprocket 210 under the attachment part 261 is caused by the game ball. Therefore, even if a bridge is generated on the lower side of the mounting portion 261, the bridge can be broken by the rotational force or vibration generated by the rotation of the sprocket 210, and ball clogging can be prevented.

Below, each component which comprises the discharge device 200 with the above-mentioned cylinder part 201 is demonstrated.
Here, the discharge device 200 is configured to be rotatable about a rotation axis set in the vertical direction (substantially perpendicular) and receives a game ball from the introduction unit 202 into which the game ball of the storage tank 220 is introduced. Is provided with a sprocket 210 having a plurality of ball receiving recesses 208,... And receives the game balls in the ball receiving recesses 208,... According to the rotation of the sprocket 210. One unit is led out to the part 20a or the lead-out part 20b for ball removal.

The stepping motor 204 is a motor that rotates by a predetermined angle every time one pulse of drive power is input, and rotates according to the pulse power output from the discharge control board 34. Note that the stepping motor 204 is controlled so as to be able to rotate, for example, by a rotation angle at which one game ball can be paid out, and receives a game ball on the outer periphery of the sprocket 210 as described later. .. Are arranged side by side in the circumferential direction so that game balls can be received in the respective ball receiving recesses 208. Therefore, the stepping motor 204 can rotate by 1/10 rotation. The discharge control board 34 controls to rotate the stepping motor 204 in accordance with the number of game balls to be paid out, and the stepping motor 204 rotates by multiplying the number of game balls to be paid out by 1/10. It will be rotated by a number.
A specific example of control of the stepping motor 204 will be described later.

  Further, as described above, the stepping motor 204 is disposed on the upper side of the drive source mounting member 206 with the rotary shaft 20z directed downward substantially vertically. Then, the sprocket 210 is fixed to the lower side of the stepping motor 204. That is, a stepping motor 204 as a drive source for driving the sprocket 210 as a rotating body is attached above the sprocket 210 by a drive source attachment member 206. Thereby, the stepping motor 204 does not protrude greatly below the storage tank 220 as in the case where the stepping motor 204 is provided below the sprocket 210, and the discharge device 200 can be arranged in a compact manner.

  Further, the drive source mounting member 206 is fixed on the left side wall 22e whose upper edge portion is lower than the upper edge portions of the right side wall 22b, the front wall 22c and the rear wall 22d of the storage tank 220. The member 206 is disposed at a position lower than the upper edge of the storage tank 220 by a distance that is about half the vertical width of the deepest portion of the storage tank 220. Therefore, even if the stepping motor 204 is disposed on the drive source mounting member 206, the length of the stepping motor 204 protruding above the storage tank 220 can be made small, and the storage tank 220 and the discharge device can be reduced. The combined size of 200 can be made compact.

A rotating member upper member 214 is attached to the rotating shaft 20z of the stepping motor 204 so as to be rotatable integrally with the rotating shaft 20z. That is, the rotary shaft 20z is inserted into the insertion port provided at the center of the rotating member upper member 214, and the rotating shaft 20z and the rotating member upper member 214 are joined so as not to rotate.
Then, the sprocket 210 is fixed to the lower end of the rotating member upper member 214, and the rotating member upper member 214 and the sprocket 210 rotate integrally around its axis, that is, around the rotating shaft 20z of the stepping motor 204. . Note that the rotation axis of the stepping motor 204 is arranged to be substantially vertical (vertical), and the central axis of rotation of the rotating body upper member 214 and the sprocket 210 is also substantially vertical.
The rotating member upper member 214 has a rotation guide part 21f whose lower part is formed in a disk shape, and an upper part of the rotating body upper member 214 that extends upward from the center part of the rotation guide part 21f. Has been. That is, an extension portion 21g extending upward along the rotation axis 20z is provided inside the rotation guide portion 21f of the sprocket 210.

The rotation guide portion 21f is formed in a disc shape, but since the extension portion 21g is disposed at the center portion thereof, the rotation guide portion 21f has an annular structure, and the upper surface thereof extends from the center side to the outer peripheral side. Inclined down. The width from the inner peripheral edge to the outer peripheral edge of the rotation guiding portion 21f is, for example, not less than the diameter of the game ball and not more than twice the diameter.
And between the induction | guidance | derivation part 22g formed in the discharge apparatus 200 side edge part of the bottom wall 22a of the above-mentioned storage tank 220, and the rotation induction | guidance | derivation part 21f arrange | positioned inside it, it is slightly from the diameter of a game ball. There is a wide gap. This interval is formed in an annular shape between the inner peripheral edge of the annular guide portion 22g and the outer peripheral edge of the annular guide portion 21f. Further, all of the portions opened above the ball receiving recesses 208,... Provided on the outer peripheral portion of the upper portion of the sprocket 210 are exposed below the space portion.

  The game balls in the storage tank 220 are introduced and introduced into the ball receiving recesses 208,... Exposed at the interval between the guide portion 22g and the rotation guide portion 21f, and rotate with the guide portion 22g. An annular space between the guide portion 21 f and the guide portion 21 f is an introduction portion 202 that introduces a game ball into the discharge device 200.

  In the above description, the introduction part 202 is between the guiding part 22g and the rotation guiding part 21f. However, the guiding part 22g and the rotation guiding part 21f are arranged at intervals between them. Since the game ball is to be introduced into the introduction part 202, the introduction part 202 may include the guide part 22g and the rotation guide part 21f.

In this case, the introduction portion 202 is provided on the bottom wall 22a, surrounds the outer periphery of the sprocket 210, is formed in a circular shape with a width of approximately one game ball, and is inclined downward toward the sprocket 210 to incline into the ball receiving recess 208. ,... Are guided circularly on the upper surface of the sprocket 210, and are inclined downward from the rotating shaft toward the ball receiving recesses 208, to guide the game balls to the ball receiving recesses 208,. And a rotation guiding portion 21f.
In addition, the height position of the inner peripheral part where the guide part 22g is lowest and the outer peripheral part where the rotation guide part 21f is lowest are substantially the same.

  Here, when the game ball is stored on the guiding portion 22g, the ball receiving recess 208,... Of the storage tank 220 so as to completely cover them, the guiding portion 22g, the ball receiving recess 208, ..., a game ball is arranged on the rotation guiding portion 21f. In addition, in the state where the game ball has fully flowed into the ball receiving recesses 208,..., The game balls are also accumulated on the ball receiving recesses 208,. Accordingly, the game balls taken into the ball receiving recesses 208,... Can be waited in the introduction portion 202 in three rows of concentric circles on the guiding portion 22g, on the ball receiving recesses 208,.

  As described above, the diameter of the annular guide portion 22g having a width corresponding to the diameter of the game ball and the front-rear width of the storage tank 220, that is, the front-rear width of the bottom wall 22a whose upper surface is the inclined portion 22h are substantially equal. Therefore, the length of the inclined portion 22h in the front-rear direction of the gaming machine 100 and the length of the introduction portion 202 in the front-rear direction of the gaming machine 100 are configured to be substantially the same. Further, all (a plurality of) ball receiving recesses 208 of the sprocket 210 face the introduction portion 202 into which game balls from the storage tank 220 are introduced.

  The extending portion 21g has a height that is about twice or more the diameter of the game ball, and has a diameter that is about the diameter of the game ball at the thinnest upper end portion. Then, by arranging the extending portion 21g on the central portion of the sprocket 210, it is possible to prevent the game ball from staying on the central portion of the sprocket 210, and to rotate the extending portion 21g to the extending portion 21g. The contact of the game balls in contact with each other is broken so that the game balls can smoothly flow toward the introduction portion 202 side.

  The sprocket 210 has the above-described plurality of ball receiving recesses 208,... On its outer peripheral portion, and its vertical height is longer than twice the diameter of the game ball, excluding the rotary shaft portion 20n described later. It is slightly shorter than 3 times. Each of the ball receiving recesses 208,... Of the sprocket 210 can receive game balls in three upper and lower stages, and the sprocket 210 has a first rotating body 20p as an upper portion and a second rotating body as a lower portion. 20q, and an intermediate rotating body 20r that is intermediate between the first rotating body and the second single body.

  Moreover, the sprocket 210 is in a state of being accommodated in the cylindrical portion 201, and the first rotating body 20p is accommodated in the first cylindrical body 21a having the largest inner diameter of the cylindrical portion 201, and the smallest inner diameter is obtained. The second rotating body 20q is accommodated in the two cylinders 21b, and an intermediate rotating body 20r that is intermediate between the first rotating body 20p and the second rotating body 20q is provided between the first cylinder 21a and the second cylinder 21b. Is accommodated in the intermediate cylinder 21c. Actually, the first rotating body 20p, the intermediate rotating body 20r, and the second rotating body of the sprocket 210 are respectively connected to the lower ends of the first cylindrical body 21a, the intermediate cylindrical body 21c, and the second cylindrical body 21b of the cylindrical body portion 201. Each lower end of the rotating body 20q is slightly raised, whereby each of the intermediate rotating body 20r of the sprocket and the second rotating body 20q of each of the intermediate cylinder 21c and the second cylinder 21b of the cylindrical body portion 201 is provided. The top is a little higher.

Further, the outer periphery of the sprocket 210 is provided with ball receiving recesses 208 along the outer periphery. Each of the ball receiving recesses 208,... The upper and lower sides of the groove are open. Note that the diameter of the arc of the groove having the arcuate cross section is slightly longer than the diameter of the game ball. Further, the distance between the deepest part (the part closest to the central axis of the sprocket 210) at each height position of each ball receiving recess 208,... And the inner peripheral surface of the cylindrical body 201 is slightly smaller than the diameter of the game ball. It has been long.
Here, the projecting portions projecting outward between the ball receiving recesses 208 of the sprocket 210 are referred to as teeth (sprocket teeth). Further, the diameter and radius at the deepest part of the ball receiving recess 208 at each height position of the sprocket 210 are referred to as a root diameter and a root circle radius. In addition, the diameter and radius of each height position of the sprocket 210 at the portion with the longest diameter that becomes the tip (tooth tip) of the tooth are referred to as a tip circle diameter and a tip circle radius.

  From the above, between the cylindrical body part 201 and the sprocket 210, a space through which a game ball can pass is formed vertically for each ball receiving recess 208,. Further, since the diameter of the second cylinder 12b is shorter than the diameter of the game ball with respect to the diameter of the first cylinder 21a, the sprocket 210 has a root diameter of the first rotating body 20p of the sprocket 210. On the other hand, the diameter of the root circle of the second rotating body 20q is shortened by about the diameter of the game ball. That is, the root diameter of the second rotary body 20q, which is the lower part of the sprocket 210, is shorter than the diameter of the root circle of the first rotary body 20p, which is the upper part of the sprocket 210. The diameter of the tip circle of the sprocket 210 corresponding to the tip of each height position is also shorter in the second rotating body 20q than in the first rotating body 20p.

Further, the upper end of the intermediate rotator 20r is integrally joined to the first rotator 20p, the root diameter is equal to that of the first rotator 20p, and the lower end is joined to the second rotator 20q. In addition, the diameter of the root circle is made equal to that of the second rotating body 20q. Accordingly, the intermediate rotating body 20r has a substantially truncated cone shape that decreases as the root diameter decreases from the top to the bottom as a shape corresponding to the intermediate cylinder 21c. Thereby, the inner peripheral surface of the intermediate cylinder 21c is an inclined surface.
The tooth length from the root to the tooth tip is the longest in the first rotating body 20p, the shortest in the second rotating body 20q, and the tooth length of the first rotating body 20p in the intermediate rotating body 20r. The tooth length of the second rotating body 20q is shortened from the top to the bottom of the tooth.

  In addition, in each of the ball receiving recesses 208,..., Game balls are arranged over a plurality of upper and lower stages, here, three upper and lower stages. That is, in each ball receiving recess 208,..., One game ball is provided in the first ball receiving recess 211 between the first cylinder 21a and the first rotating body 20p, and the intermediate cylinder 21c and the intermediate rotating body 20r. One is disposed in the intermediate ball receiving recess 213 between the second cylindrical body 21 and one in the second ball receiving recess 212 between the second cylindrical body 21b and the second rotating body 20q. That is, the sprocket 210 is configured to be able to receive a plurality of game balls in the vertical direction in each of the ball receiving recesses 208.

  That is, the ball receiving recesses 208 of the sprocket 210 are higher than the upper first ball receiving recess 211 and the first ball receiving recess 211 that receive the game balls from the introduction portion 202 for introducing the game balls of the storage tank 220. A second sphere that is arranged on a lower circumference that is smaller than the circumference of the circumference in which the first ball receiving recesses 211 are arranged, and that guides the game ball to the discharge lead-out portion 20a or the ball discharge lead-out portion 20b. A predetermined vertical dimension is provided between the receiving recess 212, the first sphere receiving recess 211, and the second sphere receiving recess 212, and the second sphere receiving recess 212 is formed from the inner surface of the first sphere receiving recess 211. And an intermediate sphere receiving recess 213 having an inclined surface that is continuous with the inner side surface.

  From the above, the sprocket 210 is configured so as to be able to receive a plurality of game balls in the vertical direction in each ball receiving recess 208,... And receives the game ball at the top of the ball receiving recess 208,. This means that game balls are derived.

  Further, each of the ball receiving recesses 208,... Is provided from the first rotating body 20p through the intermediate rotating body 20r to the second rotating body 20q, and each first rotation having a different diameter (bottom circle diameter). The same number of game balls can be arranged on the outer periphery of the body 20p, the intermediate rotating body 20r, and the second rotating body 20q. Accordingly, since the outer periphery of the first rotating body 20p is longer in circumference than the outer periphery of the second rotating body 20q, the interval between the game balls is less than the outer periphery of the second rotating body 20q. The outer periphery is wider.

  Here, if the size of the ball receiving recesses 208,... Along the circumferential direction of the sprocket 210 is increased from the bottom to the top, each ball receiving recess 208,. Since there is a possibility that the play of the game ball in the first rotary body 20p becomes too large, the tooth length of the first rotary body 20p is made longer than the radius of the game ball (from the root circle of the first rotary body 20p to the first cylinder). By setting the teeth between the center portions of the game balls (to be longer than ½ of the length to the inner surface of the body 21a), it can function as a spacer between the game balls. ing. Thereby, even if the space | interval of game balls is long, the play of a game ball is prevented from becoming large. If the play of the uppermost game ball in the ball receiving recesses 208,... Is too great, the direction of the force applied to the lower game ball is greatly changed due to the large movement of the game ball, and the game ball discharge device 200 May have a negative impact on derivation from

  In addition, it is possible to reliably receive a game ball by making the shape of the first ball receiving recess 211 surround a wide range of game balls (range of radius or more). That is, when the protruding amount of the teeth of the ball receiving recesses 208,... Is small, there are no teeth between the adjacent game balls, so the receiving area of the game balls is between the adjacent game balls. In this configuration, the receiving area changes due to the movement of the game sphere, and furthermore, due to this change, the position of each game sphere in the introduction unit 202 tends to be random, and the height difference becomes large. Although the game ball bounces greatly and support occurs in receiving the game ball, the problem as described above can be solved by lengthening the teeth in the first ball receiving recess 211 as described above.

On the other hand, in the second rotating body 20q, the interval between the game balls is narrowed so as to be in contact with each other (there is a possibility of contact). It is shorter than the radius (less than half of the length from the root circle of the second rotating body 20q to the inner surface of the second cylinder 21b), and the game ball is pushed by the teeth so that it can move in the circumferential direction. . In addition, by shortening the length of the teeth (projecting portions) constituting the second ball receiving recess 212 of the second rotating body 20q as described above (the contact portion with the game ball in the radial direction), for example, It is possible to prevent the game ball from being sandwiched between the peripheral edge of the ball extraction lead portion 20b serving as a lead outlet and the teeth constituting the second ball receiving recess 212.
From the above, the teeth that form the second ball receiving recess 212 are larger than the protruding amount of the teeth (projecting portions) that are provided to protrude outward at the outer peripheral portion of the sprocket 210 and that constitute the first ball receiving recess 211. The protruding amount of the protruding portion is set small.

  Further, with the above-described configuration, in each of the ball receiving recesses 208,..., The game balls on the lower side of the upper game ball are shifted inward so that the load on the upper game ball is lower. This prevents the game ball from hitting in the vertical direction. In addition, a configuration in which a part of the load of the upper game ball (the top game ball and the second game ball) is applied to the inner peripheral surface that is the inclined surface of the intermediate cylindrical body 21c is achieved. The load of the sphere is dispersed, and the pressure in the central axis direction of the sprocket 210 applied to the sprocket 210 is reduced. Thereby, it is possible to prevent a large load from being applied to the rotation of the sprocket 210.

  Note that the highest positions of the upper game balls of the ball receiving recesses 208,... Are on the inner periphery of the guide portion 22g, on the outer periphery of the rotation guide portion 21f (approximately the height of the upper surface of the sprocket 210), and on the teeth of the sprocket 210. It is substantially the same position as the edge (basically the height of the upper surface of the sprocket 210) so that the top of the game ball does not protrude above the upper edge of the ball receiving recess 208. As a result, the sprocket 210 rotates with the upper end of the game ball protruding from the ball receiving recess 208 of the sprocket, so that the game ball on it collides with the game ball protruding from the ball receiving recess 208,. It is possible to prevent repelling and applying a large load to the rotation of the sprocket 210. Conversely, the teeth of the sprocket 210 project upward from the game balls in the ball receiving recesses 208,... And the teeth collide with the game balls, so that the game balls repel or a large load is applied to the rotation of the sprocket 210. Can be prevented.

The lower surface of the second rotating body 20q of the sprocket 210 (the lower surface of the sprocket 210 main body) is a substantially horizontal plane, and is provided with a rotating shaft portion 20n that protrudes downward from the center portion thereof. The rotating shaft portion 20n is a columnar member that is suspended substantially vertically from the center of the lower surface of the second rotating body 20q. Further, a columnar insertion shaft portion 20m formed concentrically with the rotation shaft portion 20n is provided to project downward from the lower end of the rotation shaft portion 20n.
The insertion shaft portion 20m is inserted into a bearing hole 21n described later formed at the center of the bottom portion 216, and stabilizes the rotation of the sprocket 210 rotated by the rotation shaft 20z of the stepping motor 204 provided above. ing.

  Further, the inner diameter of the bearing hole 21n is wider than the diameter of the insertion shaft portion 20m, and is narrower than the diameter of the rotary shaft portion 20n thereon. In other words, the lower rotary shaft that is the lower rotary shaft of the sprocket 210 is formed from the rotary shaft portion 20n and the insertion shaft portion 20m, and the rotary shaft portion 20n that is the upper portion of the lower rotary shaft portion is larger in diameter than the bearing hole 21n. The insertion shaft portion 20m serving as the large diameter portion and the lower portion of the lower rotating shaft is a small diameter portion having a smaller diameter than the bearing hole 21n. As a result, the rotation shaft portion 20n is not inserted into the bearing hole 21n, and the rotation shaft portion 20n allows the interval between the lower surface of the second rotating body 20q (the lower surface of the teeth of the sprocket 210) and the upper surface of the bottom portion 216 to be described later. Thus, it is a spacer that is about the radius of the game ball. Therefore, the vertical length of the rotary shaft portion 20n is the length of the approximate radius of the game ball.

  Here, for example, when a lead-out port (ball-out lead-out part 20b) for leading out the game ball is provided at the position of the bottom part 216 that is the range of the trajectory of the game ball held at the bottom of the ball receiving recesses 208,. In addition, before the game ball falls downward from the outlet, the side edges of the teeth of the sprocket 210 on the rear side of the lowermost game ball 208 in the ball receiving recesses 208 of the sprocket 210, and the bottom 216 are guided. If the distance between the exit and the front side edge of the game ball is equal to the diameter of the game ball, the side edge of the tooth on the rear side of the game ball and the side edge of the outlet on the front side of the game ball There is a possibility that a game ball will be sandwiched between. In particular, in a state where there is almost no vertical distance between the side edge of the tooth and the side edge of the lead-out port, the game ball is easily sandwiched.

  Therefore, as described above, the approximate radius of the game ball is between the lower surface (the lower end of the teeth of the sprocket 210) of the main body of the sprocket 210 (the portion excluding the rotating shaft portion 20n and the insertion shaft portion 20m) and the upper surface of the bottom portion 216. When the game ball reaches the outlet, the sprocket 210 pushes above half of the game ball when the game ball reaches the outlet, and in this case, The place where the side edge of the lower end of the tooth contacts is an inclined surface that rises and inclines in the direction of tooth movement of the sprocket 210, and the game ball is pushed obliquely downward by the teeth of the sprocket 210. Thus, the game ball falls downward from the outlet without being sandwiched between the side edge of the outlet and the side edge of the tooth.

  If the distance between the lower end of the teeth of the sprocket 210 and the upper surface of the bottom portion 216 becomes too larger than the radius of the game ball, the game ball is always pushed obliquely downward while the sprocket 210 is rotating, and the upper surface of the bottom portion 216 is played. A ball is pressed, which is not preferable. On the other hand, as the interval becomes shorter than the radius of the game ball, the possibility that the game ball is pinched increases. Therefore, the interval is preferably approximately the radius of the game ball. Here, the interval between the lower end of the teeth of the sprocket 210 and the upper surface of the bottom portion 216 is slightly shorter than the radius of the game ball.

  As shown in FIG. 18, the bottom portion 216 closes the opened lower end portion of the cylindrical portion 201, and is formed in a substantially disc shape, and the above-described bearing hole 21n is formed in the center portion thereof. ing. The bottom portion 216 serves as a bottom for supporting the game balls received in the upper and lower stages (three stages) from below in each of the ball receiving recesses 208 of the sprocket 210 as described above, and the inner peripheral surface of the cylindrical portion 201 The game balls received in the ball receiving recesses 208 are held by the arc-shaped inner peripheral surface of the ball receiving recesses 208 of the sprocket 210 and the upper surface of the bottom portion 216.

Further, in the bottom portion 216, when the sprocket 210 rotates in the forward direction, the game balls received in the ball receiving recesses 208, ... of the sprocket 210 are led out from the discharge device 200 to the discharge flow path 248 of the chute 240. When the discharge lead-out portion 20a, which is an opening, and the sprocket 210 rotate in the opposite direction, the game balls received in the ball receiving recesses 208,... The ball extraction lead-out portion 20b, which is an opening for leading out to 247, is formed.
The discharge lead-out portion 20a and the ball discharge lead-out portion 20b are formed in the bottom 216 close to each other at a position opposite to the inclined portion 22h of the bottom wall 22a.

  The discharge lead-out portion 20a includes tooth portions between adjacent ball receiving recesses 208,... So as to form the ball receiving recesses 208,... Of the sprocket 210, and the peripheral portion of the opening serving as the discharge lead-out portion 20a. In order to prevent the game ball from being sandwiched between the two, the game ball along the circumferential direction of the game ball held in the second ball receiving recess 212, which is the lowest step in the ball receiving recess 208,. Are shifted outward from a position completely overlapping the trajectory range of a game ball having a diameter width of.

  Here, in the discharging device 200, when a special game state occurs in the game of the gaming machine 100, a lot of game balls are won within a short period of time, and a large number of prize balls are corresponding to the win. The game ball as a winning ball will be discharged, but in order to avoid a large time interval between winning and discharging the winning ball, The game ball needs to be discharged, and in this case, the sprocket 210 needs to rotate at a high speed.

In this case, as described above, there is an increased possibility that a game ball will be sandwiched between the side edge of the opening serving as the lead-out portion and the side edge of the teeth of the sprocket 210. And a gap about the radius of the game ball between the upper surface of the bottom portion 216 and the game ball is prevented from being pinched. Further, in order to prevent the game ball from being pinched reliably, the discharge derivation portion 20a for discharging the winning ball and the rental ball is provided with a trajectory range having a diameter width of the game ball along the circumferential direction of the game ball. It is arranged outside the position where it completely overlaps.
That is, the discharge outlet 20a, which is the outlet, is formed at a position shifted outward from the circular orbit of the game ball held in the ball receiving recess 208,... (Second rotary body 20q) of the sprocket 210. .

In order to prevent the game ball from being pinched, it is preferable that the discharge lead-out portion 20a is located outside the addendum circle of the second rotating body 20q, which is the lower part of the sprocket 210. , Outside the tip circle. Moreover, the position of the discharge | emission derivation | leading-out part 20a is made outside the locus | trajectory of the center of the game ball hold | maintained at the 2nd ball | bowl receiving recessed part 212 used as the lowest step of the ball | bowl receiving recessed part 208, ... of the sprocket 210. That is, the discharge lead-out part 20a is located outside the locus that does not overlap with the locus of the center of the game ball.
The bottom portion 216 is formed with a lead-out convex portion 21i that protrudes outward from the disc-shaped main body in order to dispose the discharge lead-out portion 20a outside the locus of the center of the game ball.

As shown in FIGS. 16, 17, and 18, the discharge derivation unit 20 a has a game ball along the circumferential direction in which the outer peripheral edge is outside the radius of the game ball from the locus of the center of the game ball described above. The outer edge 301 along the tangential direction from one point of the outer track of the outer circumference, and the inner side in the radial direction of the circle that becomes the track of the game ball from one point of the outer track, and slightly from the track of the center of the game ball An inner edge 302 extending in an arc shape along the trajectory of the center of the game ball slightly outside the trajectory of the center of the game ball from the outer position, and one point side of the outer trajectory of the outer edge 301 And the other end of the outer edge 301. The first edge 303 and the other edge of the outer edge 301 are connected to one end corresponding to the one point of the inner edge 302 by a substantially arcuate curve. And the other end of the inner edge 302 are connected by a substantially arcuate curve. Having shape configured from the end point side edge 304..
The diameter of the circle constituting the arc of arcuate end point edge 304 that has become a larger slightly than the diameter of the game ball.
In addition, the inner edge 302 and the starting point edge 303 of the outer peripheral edge are inclined surfaces that are inclined downward from the outer peripheral side toward the inner peripheral side. Further, these slopes are formed so as to guide the game ball from the start point side edge portion 303 toward the end point side edge portion 304 side. In addition, this slope is at least partially overlapped with the locus of the center of the lowermost game ball.

Also, a discharge ball detection sensor 217 is provided below the bottom 216 at a position overlapping the discharge lead-out portion 20a in the vertical direction, as will be described later. That is, a detection sensor (proximity sensor) 217 for counting the number of discharged balls is provided in the discharge outlet 20a as the outlet. This detection sensor 217 is a well-known sensor for a game ball, and has a rectangular plate shape as a whole. A detection hole 306 through which a game ball can pass is formed on one end side, and passes through this detection hole 306. The game ball can be detected without contact.
Then, on the lower side of the bottom portion 216, the detection sensor 217 is arranged at a position overlapping the discharge derivation portion 20a so as to close the discharge derivation portion 20a, and the detection hole 306 of the detection sensor 217 and the discharge derivation The end portion on the end point side edge portion 304 side of the portion 20a overlaps. In addition, the diameter of the detection hole 306 and the diameter of the arcuate (substantially semicircular) end-side edge 304 are substantially equal, and the outer periphery of the detection hole 306 and the end-side edge 304 are substantially overlapped. . Thereby, the game ball guided to the discharge outlet 20a is guided from the start side edge 303 to the end side 304, and flows down from the end on the end 304 side to detect the detection hole. It passes through 306.

  Except for the end on the end side edge 304 side of the discharge outlet 20a, the width of the discharge outlet 20a, that is, the distance between the outer edge 301 and the inner edge 302 is based on the diameter of the game ball. In addition to being shortened, the game ball is spread from the start point side edge portion 303 toward the end point side edge portion 304, whereby the game ball introduced to the start point side of the discharge derivation portion 20a is guided to the end point side. Will flow downward on the end point side.

Further, in a portion other than the detection hole 306 that overlaps the detection hole 306 of the discharge derivation portion 20a, that is, a portion excluding the end portion on the end point side, the detection sensor 217 (portion excluding the detection hole 306) and the discharge derivation portion 20a are provided. The detection sensor 217 is exposed from the discharge outlet 20a, but the distance between the outer edge 301 and the inner edge 302, the distance between the upper surface of the detection sensor 217 and the upper surface of the bottom 216, A game ball moving from the starting point side to the ending point side of the discharge derivation unit 20a from the derivation unit surrounding wall 21k, which will be described later, does not touch the upper surface of the detection sensor 217.
When the lowermost game ball of the ball receiving recesses 208,... Is transported to the position of the discharge lead-out portion 20a by the rotation of the sprocket 210, the inner edge portion 302 and the starting point will be described. The slope of the side edge 303 that is inclined downward toward the discharge outlet 20a side and the distance between the outer edge 301 and the inner edge 302 are widened from the starting edge 303 to the ending edge 304. , The centrifugal force due to the rotation of the sprocket 210 and the length from the tooth root to the tooth tip between the ball receiving recesses 208 at the bottom of the sprocket 210 are shorter than the diameter of the game ball, Since the rotation shaft side of the sprocket 210 is pushed from the center, the game ball is guided to the discharge lead-out portion 20a outside the center trajectory of the game ball.

Then, the game balls in the lowermost stage (second ball receiving recess 212) of the ball receiving recesses 208, ... flow down to the discharge outlet 20a. At this time, the above-mentioned rib 21e causes the uppermost game balls (the intermediate ball receiving recess 213 and the first ball receiving recess 211) to flow to the discharge outlet 20a of the ball receiving recesses 208,. Although it remains above the lower stage, the game ball in the upper stage from the lowermost stage moves downward by rotating to a portion without the rib 21e. Accordingly, the game ball in the middle stage (intermediate ball receiving recess 213) moves to the lowermost stage, and the game ball in the uppermost stage (first ball receiving recess 211) moves to the middle stage, so that the uppermost stage of the ball receiving recesses 208,. Becomes empty, and a game ball can be received in the uppermost stage of the ball receiving recesses 208.
That is, by rotating the sprocket 210, the game ball is received at the uppermost part of the ball receiving recesses 208,... And the lowermost game ball is led out.

As described above, the lead-out convex portion 21 i of the bottom portion 216 protrudes outward from the disc-shaped bottom portion 216 body, and is thus exposed to the outside of the cylindrical portion 201.
Moreover, the above-mentioned notch part 21d is formed in the position corresponding to the said protrusion convex part 21i of the 2nd cylinder 21b used as the lower part of the cylinder part 201. As shown in FIG. In addition, the bottom portion 216 is provided with a lead-out portion surrounding wall 21k so as to surround the lead-out convex portion 21i exposed from the notch portion 21d. The lead-out portion enclosing wall 21k is erected on the upper surface of the bottom portion 216, includes the outer periphery of the lead-out convex portion 21i, and excludes the start-side edge portion 303 and the inner edge portion 302 of the discharge lead-out portion 20a. It is formed so as to surround 301 and the end side edge portion 304. That is, the lead-out portion enclosing wall 21k is provided so as to surround the discharge lead-out portion 20a except for the side where the game ball of the discharge lead-out portion 20a flows.

The lead-out enclosure wall 21k surrounds the discharge lead-out portion 20a except for the side where the game ball flows into the discharge lead-out portion 20a, so that the game ball can surely flow down into the discharge lead-out portion 20a. It has become.
Further, a flow-down guide portion 21m that protrudes toward the start point side is provided at a portion that is substantially above the center of the left and right width of the end point side edge portion 304 of the inner peripheral surface of the lead-out portion surrounding wall 21k. The flow-down guide portion 21m is slightly longer than the radius of the end point side edge portion 304 that is substantially semicircular, and protrudes beyond the center of the semicircle of the end point side edge portion 304 of the discharge outlet portion 20a. .

The lower surface of the distal end portion of the flow guide portion 21m has a height from the upper surface of the bottom portion 216 that is slightly higher than the diameter of the game ball. Further, the lower surface of the flow guide portion 21m It is configured to be curved in a substantially arc shape and descend downward as it goes toward the inner peripheral surface side of the part enclosing wall 21k.
As a result, the advancing direction in which the lower surface of the flow guide portion 21m is substantially horizontal in the gaming ball flowing down on the discharge derivation portion 20a is smoothly converted downward, and the game ball is smoothly moved into the discharge derivation portion 20a. It is designed to flow down. As a result, the game ball rebounds at the discharge derivation portion 20a, and the flow of the game ball to the discharge derivation portion 20a is delayed, colliding with the game ball to be discharged next, and hindering the discharge of the game ball. It can be prevented from coming out.

  The lead-out encircling wall 21k covers the periphery of the lead-out convex portion 21i exposed from the notch 21d of the cylindrical body portion 201, but the upper portion of the lead-out convex portion 21i is in an open state. A top plate portion 21h is formed on the outer side of the circumference of the cylindrical body portion 201 (second cylindrical body 21b) from the cutout portion 21d of the cylindrical body portion 201 of the wall 21k.

Further, since the lead-out surrounding wall 21k is formed so as to protrude from the cutout portion 21d of the cylindrical portion 201, it is a concave portion when viewed from the inner peripheral surface side of the cylindrical portion 201, and is guided into this concave portion. The game ball is derived from the discharge deriving unit 20a.
Accordingly, a lead-out concave portion 205 for leading out the game ball is formed by denting a portion corresponding to the second ball receiving concave portion 212 in the cylindrical portion 201 serving as a side wall of the storage portion 203 to the outside, and the lead-out concave portion 205 is formed. The discharge lead-out portion 20a (the unclosed portion) is formed at the lower end of the flow-out of the lead-out convex portion 21i serving as the bottom of the discharge lead.

  Here, the portion other than the detection hole 306 that overlaps the detection hole 306 of the discharge outlet 20a, that is, the portion other than the end portion on the end point side, is overlapped with the detection sensor 217 and is closed. The closed portion of the discharge outlet 20a is not necessarily opened, and may be closed at substantially the height position of the upper surface portion of the detection sensor 217. In this case, the closed portion becomes the bottom of the lead-out recess 205. The inclined inner edge portion 302 and outer edge portion 301 of the discharge lead-out portion 20a described above serve as the bottom portion of the lead-out recess portion 205, and the bottom portion of the lead-out recess portion 205 is the upper surface on the inner side of the cylindrical portion 201 of the bottom portion 216, That is, it is one step lower than the bottom of the storage portion 203, and the inclined inner edge portion 302 of the discharge outlet portion 20a is a step portion of these bottom portions. In addition, a portion that overlaps the detection hole 306 of the detection sensor 217 of the discharge derivation unit 20a becomes the discharge derivation unit 20a. Even in the above-described configuration, the portion that does not overlap with the detection hole 306 of the discharge derivation portion 20a is closed by the detection sensor 217, and the portion that substantially overlaps the detection hole 306 vertically with the discharge derivation portion 20a. Become.

  From the above, when a bottom portion that closes a part of the discharge derivation portion 20a is provided, the bottom portion of the lead-out recess portion 205 is formed with a step below the bottom portion of the storage portion 203. An inclined surface (inclined inner edge 302) is formed from the bottom to the bottom of the lead-out recess 205.

  Further, a portion surrounding the end portion on the inner edge portion 302 side of the end point side edge portion 304 of the lead-out portion surrounding wall 21k is integrally joined with a flow guide wall 21p of a ball discharge lead-out portion 20b described later, and this lead-out portion enclosure A part of the wall 21k and the flow guide wall 21p are formed so as to protrude from the outer peripheral portion in the cylindrical portion 201 on the upper surface of the bottom portion 216. Note that at least a part of the protruding portion is included in the range of the trajectory of the game ball in the lowermost stage (second ball receiving recess 212) in the ball receiving recess 208,. However, the protruding portion is between the discharge lead-out portion 20a and the ball discharge lead-out portion 20b that are close to each other, and in this portion, the lowermost game ball is discharged by the discharge lead-out portion 20a or the ball discharge lead-out portion by the rib 21e. When it flows down to the derivation unit 20b, the game ball above it is prevented from flowing down to the lowest level, and there is no game ball at the lowest level. Therefore, even if a part of the outlet enclosing wall 21k and the flow-down guide wall 21p protrude on the movement trajectory of the game ball, the movement of the game ball in the ball receiving recess 208, ... is not affected. Yes.

The ball extraction lead-out portion 20b formed on the bottom portion 216 has a substantially square shape in which each side edge (side) as an outer periphery is substantially parallel to each piece on the outer periphery of the storage tank, and the inclined portion 22h of the bottom wall 22a. Only the side edge (side) on the opposite side is an opening having an arc shape, and has a diameter slightly larger than the diameter of the game ball.
The ball removal lead-out portion 20b has a circumferential movement trajectory due to the rotation of the sprocket 210 of the game ball held in the second ball receiving recess 212 of the second rotating body 20q, which is the lower portion of the sprocket 210. The game balls are arranged so as to substantially overlap the range of the diameter width of the game balls. In other words, the locus of the center of the game ball overlaps with the approximate center of the ball removal lead-out portion 20b.

Moreover, the peripheral part of the derivation | leading-out part 20b for ball removal becomes a slope inclined downward toward the inner side, and guides a game ball to the center side of the derivation | leading-out part 20b for ball removal.
Further, the flow guide wall 21p is provided adjacent to the ball removal lead-out portion 20b at the front side of the game ball moving direction when the sprocket 210 of the ball removal lead-out portion 20b is reversely rotated. 216 is erected substantially vertically from the upper surface. Further, the side surface of the flow guide wall 21p has an arcuate surface shape in which the center side is recessed from the left and right side edges. A flow guide portion 21q having the same shape as the flow guide portion 21m described above is formed on the inner side edge of the flow guide wall 21p, and the traveling direction of the game ball is lowered from the horizontal direction in the same manner as the flow guide portion 21m. It is designed to guide in the direction.
The ball removal lead-out portion 20b overlaps the trajectory of the game ball as described above, so that the game ball is more easily sandwiched than the discharge lead-out portion 20a. The speed at which the sprocket is rotated in the reverse direction for discharging the game ball from the ball discharger 20b, as compared to the speed at which the sprocket 210 is rotated in the forward direction for discharging the game ball from the discharge outlet 20a. As described above, the space between the upper surface of the bottom portion 216 and the lower surface of the main body of the sprocket 210 is spaced about the radius of the game ball, so that the game ball is separated from the side edge of the ball removal lead-out portion 20b and the sprocket. It is possible to sufficiently prevent pinching (balling) between the teeth of 210.

  That is, the ball removal lead-out portion 20b serving as a lead-out port is formed on the rotation path of the game ball received in the ball receiving recess 208,... (Second ball receiving recess 212) in the bottom 216, and the sprocket 210 is connected to the sprocket 210. A gap is formed between the lower surface of 210 and the upper surface of the bottom portion 216 (for example, for preventing ball balls when guiding a game ball to the outlet).

Further, the game ball removal unit 20b is used for replacement or maintenance of the gaming machine, and it is necessary that the game ball is discharged faster as the game ball is paid out. Absent.
The discharge lead-out portion 20a can have the same configuration as the above-described ball discharge lead-out portion 20b, and the ball discharge lead-out portion 20b can have the same configuration as the above-described discharge lead-out portion 20a. Is possible.
The storage portion 203 is constituted by the bottom portion 216 having the above-described discharge derivation portion 20a and ball discharge derivation portion 20b, and the cylindrical portion 201. That is, the discharge device 200 of the gaming machine 100 houses the sprocket 210 and discharges the game ball from the ball receiving recess 208,... To the bottom 216 to the downstream side (discharge discharge portion 20a and ball discharger). And a storage portion 203 in which a lead-out portion 20b) is formed.

  In addition, the outlet is a discharge outlet 20a provided with a detection sensor 217 for detecting a discharge ball, and a ball outlet for extracting the game ball of the storage tank 220 to the outside of the gaming machine 100 (a recovery bin of the island facility). , And the game ball of the ball receiving recesses 208,... Is derived from either the discharge derivation unit 20a or the ball extraction derivation unit 20b by changing the rotation direction of the sprocket 210. In addition, the lead-out portion 20b for ball removal is formed on the rotation path of the lowermost game ball of the ball receiving recess 208,.

  The bottom member 218 is generally thin (having a short axial length) and has a bottomed cylindrical shape. The diameter of the bottom member 218 is substantially the same as that of the second cylindrical body 21b serving as the lower end of the cylindrical body 201. Yes. A plurality (three) of fixing pieces 311 are provided on the upper portion of the outer peripheral portion of the bottom member 218 at intervals in the circumferential direction. The fixed piece 311 is formed to correspond to fixed bosses 312 formed on the outer peripheral portion of the lower second cylindrical body 21b at intervals in the circumferential direction. And the bottom member 218 is fixed to the lower end part of the cylindrical part 201 by screwing the fixing pieces 311... To the fixing boss 312. Further, the bottom 216 is positioned and placed on the bottom member 218, and the bottom 216 is fixed to the cylinder body 201 by fixing the bottom member 218 to the cylinder body 201.

The bottom member 218 is provided with a cylindrical fitting cylinder 315 having a fitting hole into which a lower end portion of a cylindrical bearing hole 21n protruding downward from the center part of the bottom surface of the bottom part 216 is fitted. It has been.
In addition, the bottom member 218 is provided with a square cylindrical sensor mounting portion 313 that fixes the detection sensor 217 in a accommodated state. The detection sensor 217 is configured such that the detection hole 306 partially protrudes outward from the cylindrical portion 201 corresponding to the discharge lead-out portion 20a, and the sensor mounting portion 313 is also a cylindrical bottom member 218 main body. A part (a part in which the detection hole 306 of the detection sensor 217 is arranged) protrudes outward.

At a position overlapping the detection hole 306 of the detection sensor 217 on the bottom plate of the bottom member 218, a game ball can pass so as to overlap with the detection hole 306, and a hole having substantially the same diameter as the detection hole 306 is formed. The game ball is caused to flow down from the discharge outlet 20a to the inlet of the discharge channel 248 of the chute 240 via the.
Further, a cylindrical ball removal cylinder portion 314 having an inner periphery of the same shape as the ball removal extraction portion 20 b is formed immediately below the ball removal extraction portion 20 b of the bottom portion 216 of the bottom member 218. The game ball is allowed to flow down from the ball removal lead-out portion 20b to the inlet of the ball removal passage 247 of the chute 240 via the ball removal cylinder portion 314.

In the gaming machine as described above, the storage tank 220 and the discharge device 200 discharge the game balls as follows.
First, a game ball is supplied to the storage tank 220 from an island facility (outside the game machine 100) of the game store where the game machine 100 is installed, and the amount of game balls that do not overflow to the storage tank 220 basically. Is stored.

  The game ball stored in the storage tank 220 is opposed to one end portion of the storage tank 220 provided with the discharge device 200 due to the horizontal inclination of the inclined portion 22h of the upper surface of the bottom wall 22a. It will be in the state which can flow from the other edge part used as a side to one edge part. Further, the inclined portion 22h is also inclined in the front-rear direction of the gaming machine 100 corresponding to the rotation direction of the sprocket 210, and a guiding stage in which a step is provided lower than the upstream side of the inclination. Since the portion 22i is provided, as shown in FIG. 11, in the direction along the rotation direction of the sprocket 210, the portion on the side advanced in the rotation direction of the sprocket 210 from the boundary portion between the inclined portion 22h and the guide portion 22g. A game ball can flow.

  As a result, the outer peripheral guide portion 22g and the inner peripheral side guide portion 22g, which are provided in the bottom wall 22a of one end portion that is in a state of being overlapped with the discharge device 200 of the storage tank 220, are arranged annularly and concentrically with each other. A game ball is supplied from the other end of the storage tank 220 onto the rotation guide portion 21f and the introduction portion 202 disposed between them, and the sprocket 210 is rotated in response to the rotation of the sprocket 210. A game ball is introduced into the ball receiving recesses 208,... Exposed from the introduction portion 202 of the outer peripheral portion.

  Further, when the game ball in the storage tank 220 flows from the other end portion to the one end portion side, the above-described guide portion 22g, introduction portion 202, The height of the game balls stacked on the rotation guide portion 21f is lowered. That is, the height limiting member 260 of the storage tank 220 is disposed slightly from the inclined portion 22h side with respect to the boundary portion between the inclined portion 22h and the guide portion 22g, and the above-described curved portion 263 on the distal end side and the extending portion 262 thereafter. Thus, the height of the game balls stacked on one end side is made lower than the height of the game balls stacked on the other end side from one end of the storage tank 220.

Thereby, the height of the game ball stacked on the guiding portion 22g and the inner portion thereof is lowered, and the ball pressure directed downward by the load of the game ball is reduced in this portion. Further, the height restricting member 260 is formed in a comb-like shape by notches 265,... Arranged approximately at the diameter interval of the game ball, so that each comb-tooth portion 264,. By bending, when the game ball flows between the height limiting member 260 and the bottom wall 22a of the storage tank 220, the game ball meshes between the height limiting member 260 and the bottom wall 22a. to form a bridge it can be prevented from becoming fluidized and Dzu leprosy state.

  In addition, since the attachment portion 261 of the height limiting member 260 is attached to the drive source attachment member 206 with the stepping motor 204 placed thereon, when the stepping motor 204 is operated, vibrations generated thereby are driven. Even if the bridge is generated from the source mounting member 206 to the height limiting member 260, it can be broken.

  Then, at the end of the storage tank 220 on the discharge device 200 side, the game balls stored in the storage tank 220 are introduced into the discharge device 200 by the height limiting member 260 and the drive source mounting member 206 as described above. The height of the game balls stacked on the introduction part 202 is limited, and the ball pressure based on the load of the game ball is reduced in the introduction part 202 and its vicinity so that the inside of the discharge device 200 (the ball of the sprocket 210 can be smoothly removed from the introduction part 202. A game ball can be introduced into the receiving recesses 208...

  In addition, in the introduction portion 202 having substantially the same width as the storage tank 220, ten ball receiving recesses 208 provided on the outer peripheral portion of the sprocket 210 whose upper surface of the outer peripheral portion rotates about a substantially horizontal and substantially vertical rotation axis. ,... Are in a state where all the upper openings face, and further, a guiding portion 22g that is inclined inward from the outer peripheral side of the introducing portion 202 is formed, and a rotation guiding portion 21f is formed on the upper surface of the sprocket 210 inside the introducing portion 202. As a result, the game ball can flow in directly from the introduction portion 202, from the outer guiding portion 22g, and from the inner rotation guiding portion 21f. In addition, since the game balls are allowed to flow under substantially the same conditions regardless of the rotational position of the ball receiving recesses 208,... If possible, game balls can flow in anytime.

  As a result, the game ball can surely flow into the ball receiving recess 208. Also, since the game balls can flow into the ball receiving recesses 208,... In the upper and lower three stages, a game ball is newly added by the time the ball receiving recesses 208,. Even if the ball does not flow into the ball receiving recesses 208,..., One or two game balls are arranged in the ball receiving recesses 208,..., And the ball receiving recesses 208,. Although there is no game ball in the ball receiving recesses 208,... In spite of having moved to the position, it is possible to prevent a situation in which the game ball is not led out.

  Therefore, the game ball can be led out smoothly by the rotation of the sprocket 210. In other words, in the ball receiving recesses 208,..., If the game balls are held in three upper and lower stages, it is possible to prevent a situation in which the game balls are not led out if the game balls flow in during three rounds of the sprocket 210. Can do. Further, as described above, since the game ball can flow into the ball receiving recesses 208,... At any time, even when two or more empty spaces are generated in the ball receiving recesses 208,. There is no problem even if there is a ball receiving recess 208,... In which a game ball does not flow in during a round of the sprocket 210.

  Further, if the game balls can be held in the upper and lower three stages in the ball receiving recesses 208,..., The upper game ball is loaded on the lowermost game ball. The game balls on the lower side are arranged obliquely inward with respect to the game balls on the upper side without arranging the game balls in a vertical line. For example, at the position of the intermediate ball receiving recess 213 where the middle game ball of the three upper and lower game balls of the sprocket 210 is arranged, the inner cylinder 21 c of the cylinder portion 201 serving as the side wall of the storage unit 203 Since the peripheral surface is an inclined surface that contacts the diagonally lower side of the middle game ball, the inclined surface receives a part of the load of the game ball arranged at the uppermost stage and the middle, and the lowermost game The load applied to the ball by the upper game ball can be reduced, thereby preventing the sprocket 210 from being obstructed.

In the ball receiving recesses 208,..., The game balls received from the uppermost stage sequentially move down to reach the lowermost stage, and then are derived from the discharge derivation unit 20a or the ball extraction derivation unit 20b. Become.
At this time, if the sprocket 210 rotates at a high speed, the game ball to be derived is sandwiched between the peripheral edge of the outlet and the teeth of the sprocket 210 as described above, and the game ball cannot be derived, and the sandwiched game If the ball is not removed, the rotation of the sprocket 210 cannot be resumed.

Therefore, for example, by providing an interval about the radius of the game ball between the upper surface of the bottom portion 216 of the storage unit 203 in which the sprocket 210 is stored and the lower surface of the sprocket 210 (the lower edge of the teeth), the game ball Is lowered downward at the lead-out port (ball-drawing lead-out part 20b), the state where the teeth of the sprocket 210 press the slope inclined downward from the top above the half height position of the game ball, that is, a state of pressing the game ball obliquely downward, it is possible to prevent the game balls are sandwiched as described above.
In addition, as shown in FIG. 19 (A), the peripheral portion of the ball removal lead-out portion 20b is a slope that slopes downward toward the inside, so that the game ball is a peripheral portion of the ball discharge lead-out portion 20b. At the stage where the game ball is lowered, the teeth of the sprocket 210 are on the upper side with respect to the intermediate height of the game ball, and the game ball is pushed obliquely downward before the game ball flows down into the ball outlet lead-out portion 20b. It becomes possible to prevent the game ball from being pinched more reliably.

Further, in the discharge lead-out portion 20a as the lead-out port, the portion serving as the lead-out port is arranged so as to be shifted outward from the tooth tip circle of the second rotating body 20q that is the lowest stage of the sprocket 210, The game ball is not sandwiched between the peripheral edge of the discharge outlet 20a and the teeth of the sprocket 210.
For example, as shown in FIGS. 17 (A) and 18 (A), a game ball adjacent to the discharge derivation unit 20a on the near side of the discharge derivation unit 20a is outside the center locus. In the portion 20a, the centrifugal force at the time of rotation of the sprocket 210 and the inner peripheral edge portion of the discharge lead-out portion 20a are positioned so as to overlap the trajectory of the center of the game ball at the time of rotation of the sprocket 210. It is guided by an inclined surface that inclines downward toward the lead-out portion 20a side (outside the center trajectory of the game ball). Then, as shown in FIGS. 17B and 18B, the game ball is further pushed by the teeth of the sprocket 210 and approaches the discharge lead-out portion 20a. At this time, the traveling direction of the game ball is changed. It does not have an arc shape, and is along the tangential extension of the rotation path of the game ball at the time of FIG. 17 (A) and FIG. 18 (A).
Then, as shown in FIGS. 17C and 18C, before the game ball reaches the end of the discharge lead-out portion 20a where the game ball can flow downward, the game ball is removed from the sprocket 210 teeth. In a stage where the game ball is completely separated to the outside and the game ball flows downward from the discharge deriving portion 20a, the game ball is sandwiched between the teeth of the sprocket 210 and the end point side edge 304 of the discharge deriving portion 20a. It becomes impossible.

From the above, in the discharge device 200, the number of game balls corresponding to the rotation angle of the sprocket 210 is surely discharged, and the game ball is sandwiched at the outlet, so that the sprocket 210 does not rotate. it is possible to prevent the. In particular, when the sprocket 210 does not rotate, there is a possibility that work by an attendant may be necessary, but by preventing this reliably, the player becomes unable to play a game while waiting for the attendant's work. Therefore, it is possible to reliably prevent the occurrence of a situation in which the player is dissatisfied with being unable to play the game.
Although it is conceivable to reversely rotate the sprocket 210 in order to eliminate the non-rotatable state, there is a possibility that the game ball may be discharged from the ball removal lead-out portion 20b due to the reverse rotation, and such control is also problematic. There is.
Moreover, cost reduction can be achieved by reducing the work by the staff.

In the control of the discharge control board 34 of the discharge device 200 as described above, a game ball won from a sensor of each winning port (including various winning devices) provided in the game area on the front side of the game board 1 during the game. When a signal indicating this is input to the main control board 30, a prize ball command including data on the number of prize balls corresponding to each winning opening is output from the main control board 30 to the discharge control board 34.
On the discharge control board 34, the stepping motor 204 receives a number of pulses corresponding to the above rotation angle so as to rotate the sprocket 210 (the rotation shaft 20z of the stepping motor 204) by the rotation angle corresponding to the number of prize balls. Output sequentially.

  Here, assuming that ten ball receiving recesses 208,... Are provided at equal intervals in the circumferential direction on the outer periphery of the sprocket 210 as described above, 1/10 rotation, that is, 36.0 degrees each. One game ball is derived each time the sprocket 210 rotates. When the game ball is derived, the detection sensor 217 detects the game ball to be discharged and outputs a detection signal to the discharge control board 34. The discharge control board 34 corresponds to the rotation angle of the sprocket 210. Can be detected.

  Further, since the stepping motor 204 of this example has a rotation angle of one step, that is, a rotation angle with respect to one pulse input of 1.8 degrees, for example, it is necessary to pay out one game ball. It is necessary to input 20 pulses to rotate 0 degree. Further, when the sprocket 210 is rotated in the forward direction when the prize ball is paid out, the discharge control board 34 outputs a pulse to the stepping motor 204 every 3 ms (milliseconds). Therefore, when the stepping motor 204 is continuously rotated, a pulse is output 20,000 times in one minute, that is, 60000 ms, and rotates 36000 degrees, that is, 100 times. Accordingly, the sprocket 210 can be rotated at 100 revolutions per minute in the forward direction, and is set so that a maximum of 1000 game balls can be discharged per minute.

  Therefore, for example, when a prize ball command indicating that the number of prize balls is 5 is output to the discharge control board 34, 100 pulses every 3 ms to rotate the sprocket 210 by 36.0 × 5 degrees. As a result, the sprocket 210 rotates 180 degrees in 300 ms, that is, 0.3 seconds, and five game balls are sequentially paid out. Then, the discharge control board 34 checks whether or not the number of game balls corresponding to the data of the number of prize balls has been discharged based on the detection signal from the detection sensor, and if the number of game balls actually detected is small Then, the sprocket 210 is rotated again by the number of game balls that are insufficient. That is, each time one game ball is insufficient, the sprocket 210 is rotated again by 36.0 degrees as a rotation angle for discharging one game ball.

  By this control, even if a situation occurs in which the game balls are not discharged from the ball receiving recesses 208 rotated to the position where the game balls are led out, it is possible to discharge the game balls having a predetermined number of prize balls. . Further, the discharge control board 34 can discharge game balls even based on a ball rental command input from a ball lending machine provided adjacent to the game machine 100. In this case, the control of the payout of the rental balls in the discharge device 200 is basically the same as the payout of the prize balls.

  Further, in the control of the payout of the prize balls and the rental balls, when the game ball detection signal from the half-end sensor 22k is interrupted, that is, a signal indicating that the game ball cannot be detected is input to the discharge control board 34. In such a case, the discharge device 200 is not operated. Thereby, when there is a possibility that there is not enough game balls required for one discharge in the storage tank 220, the game balls are not discharged.

  In addition, a ball removal switch (not shown) is provided on the back side of the front frame 120. The ball removal switch is connected to the discharge control board 34, and an ON signal based on the switch operation is input to the discharge control board 34 from the ball removal switch. In this case, the discharge control board 34 outputs a pulse to the stepping motor 204 so as to rotate the sprocket 210 in the reverse direction. In this case, the pulse interval for rotating the sprocket 210 in the forward direction to discharge the above-mentioned prize balls and rental balls is 3 ms, but the pulse interval is doubled to 6 ms. It has become. As a result, the rotation speed in the forward direction of the sprocket 210 was 100 rotations per minute, whereas the rotation speed in the reverse direction for ball removal is halved to 50 rotations per minute.

By reducing the rotation speed of the sprocket 210, the sprocket 210 rotates in the reverse direction, and the game ball is derived from the ball removal lead-out portion 20b provided so as to overlap the rotation trajectory of the game ball. It can prevent more reliably that it is pinched | interposed between the tooth | gear of the sprocket 210 tooth | gear, and the peripheral part of the derivation | leading-out part 20b for ball removal.
In addition, since all the game balls in the storage tank 220 are basically discharged at the time of ball removal, pulses are continuously output to the stepping motor 204 at predetermined 6 ms intervals when the ball removal switch is on. However, when a signal indicating that a game ball is not detected from the half-end sensor 22k is input to the discharge control board 34, a predetermined time after the signal is input (for example, after several seconds to several tens of seconds have elapsed) ) The pulse output is automatically stopped and the stepping motor 204 is automatically stopped. Thereby, if the storage tank 220 becomes empty during the ball removing operation, the discharge device 200 automatically stops.

Next, a modification of the above-described embodiment will be described. In each modified example described below, only different parts from the above embodiment will be described, and the description of the same configuration as the above embodiment will be omitted. Accordingly, in each of the modifications described below, the portions that are not described have basically the same configuration as that of the above embodiment.
In the first modified example, as shown in FIG. 19B, the sprocket 210 of the ball removal lead-out portion 20b is reversely rotated in the ball discharge lead-out portion 20b of the bottom portion 216 constituting the bottom surface of the storage portion 203. In this case, a step portion 209 that is one step lower than the upper surface of the bottom portion 216 is provided on the front side of the game ball of the ball removal lead-out portion 20b (during reverse rotation), and the sprocket 210 ( The distance to the lower surface of the teeth of the sprocket 210 is longer than the radius of the game ball.
That is, a stepped portion 209 is formed which is an edge portion of the ball extraction leading portion 20b serving as a lead-out port and has a stepped downward from the bottom portion 216 of the storage portion 203 in the direction in which the game ball enters the lead-out port. The dimension between the lower surface of the step and the upper surface of the step portion 209 is set larger than the radius of the game ball.

  Thus, for example, when the distance between the upper surface of the bottom portion 216 serving as the bottom surface of the storage portion 203 and the lower surface of the sprocket 210 is approximately the radius of the game ball, and the game ball is slightly shorter than the radius of the game ball. When moving to the stepped portion 209 in front of the extraction lead-out portion 20b, the stepped portion 209 lowers the position of the game ball by one step. As a result, the contact position between the game ball and the tooth of the sprocket 210 that pushes the game ball in the rotational direction becomes slightly higher than the center of the game ball, and the tooth of the sprocket 210 is inclined downward as described above. It is possible to prevent the game ball from being pinched between the peripheral edge of the outlet and the teeth of the sprocket 210 more reliably.

Further, by making the distance between almost the entire upper surface of the bottom portion 216 serving as the bottom surface of the storage portion 203 and the lower surface of the sprocket 210 slightly larger than the radius of the game ball, a structure in which the game ball is more difficult to be sandwiched can be achieved. However, in this case, a force that is always pressed against the bottom 216 side acts on the lowermost game ball of the ball receiving recesses 208,... And a load is applied to the rotation of the sprocket 210. However, when the distance between the upper surface of the stepped portion 209 and the lower surface of the sprocket 210 is made slightly larger than the radius of the game ball, only the game ball moved onto the stepped portion 209 is pressed against the bottom 216 side. Therefore, the game ball can be reliably prevented from being caught at the outlet without applying a large load to the rotation of the sprocket 210.
In addition, when the structure of the discharge | emission derivation | leading-out part 20a is made into the structure similar to the derivation | leading-out part 20b for ball removal, also in the derivation | leading-out part 20a for discharge, the above-mentioned level | step-difference part 209 in the front direction of the forward direction of a game ball is also mentioned. May be provided.

  In the second modification, as shown in FIGS. 20A and 20B, the mounting portion 261 of the height limiting member 260 is provided on the drive source mounting member 206 and extends in the front-rear direction of the gaming machine. The curved portion 263 of the height limiting member 260 and the like are pivotally attached to the drive source attachment member 206 by the shaft 268 so as to move up and down. Further, the height limiting member 260 is provided with an interlocking portion 269 extending from the attachment portion 261 in the direction of the rotation axis 20z of the stepping motor 204. The tip of the interlocking portion 269 is not in contact with the rotating shaft 20z of the stepping motor 204, but is formed on the upper surface of the extending portion 21g of the rotating body upper member 214 provided around the rotating shaft 20z. The length is in contact with the portion 271.

Then, as shown in FIG. 20A, the rotation range of the height limiting member 260 includes a position where the interlocking portion 269 contacts the lower surface of the drive source mounting member 206 (a position where the bending portion 263 is lowest), As shown in FIG. 20B, it is between the position where the interlocking portion 269 contacts the contact portion 271 that is the upper surface of the extending portion 21g (the position where the bending portion 263 is highest).
Further, the height limiting member 260 that can be rotated is provided with an urging member 272 made of an elastic member (spring) such as a torsion spring attached to the attachment shaft 268, for example. The bending portion 263 is biased in a lowering direction, that is, in a direction in which the interlocking portion 269 moves upward and comes into contact with the lower surface of the drive source mounting member 206. As a result, the height limiting member 260 is at the lowest position unless the height limiting member 260 is loaded from a game ball stored in the storage tank 220 as will be described later, and the interlocking portion 269 is connected to the drive source mounting member 206. It is in contact with the lower surface of.

  When the amount of game balls that are stacked higher than the height limiting member 260 flows into the storage tank 220, the curved portion 263 that curves upward from the substantially horizontal direction (obliquely upward direction) becomes the bottom wall 22a (inclined portion) of the storage tank 220. 22h) is moved upward against the urging force of the urging member 272 by the ball pressure from the game ball on the upper side of the inclination, and the interlocking portion 269 contacts the contact portion 271 on the upper surface of the extending portion 21g. Yes.

Further, as shown in FIG. 21, the interlocking portion 269 has a lateral width narrower than the height limiting member 260 and extends from a central portion in the front-rear direction of the gaming machine 100 of the mounting portion 261 of the height limiting member 260. It extends to the upper surface side of the protruding portion 21g. In addition, the lower surface of the interlocking portion 269 (at least the portion that can come into contact with the contact portion 271) is formed in an inverted triangular cross section so that the center portion is the lowest and the left and right side edge portions are the highest.
On the other hand, on the upper surface of the contact portion 271, a plurality of convex portions 273,... The cross-sectional shape of the convex portions 273... May be any shape such as a quadrangle and a triangle. Therefore, when the rotating member upper member 214 rotates together with the sprocket 210 in a state where the tip of the interlocking portion 269 is lowered and is in contact with the contact portion 271, the contact portion 271 is also rotated, and the bottom surface of the tip of the interlocking portion 269 is rotated. The convex portions 273,... Move below the pointed portion, whereby the interlocking portion 269 moves up and down (vibrates up and down). As a result, the height limiting member 260 connected to the interlocking portion 269 also vibrates up and down.

  In other words, the height restriction member 260 is attached to the attachment portion 261 by the attachment shaft 268 extending in the left-right direction of the gaming machine 100, and the bending portion 263 moves upward about the attachment shaft 268 and moves downward. And a linking member 269 that extends in the axial direction of the sprocket 210 from the mounting portion 261 and a biasing member 272 that biases the height limiting member 260 downward. The rotating shaft 210 includes a contact portion 271 that rotates about the rotating shaft and can contact the interlocking portion 269 and is formed in an uneven shape. When the height limiting member 260 is in the lower state, the interlocking portion 269 is the contact portion. The interlocking portion 269 is in contact with the contact portion 271 with the height limiting member 260 in the up state without contacting with the contact portion 271.

  Thereby, when the height limiting member 260 is in the upper state in the storage tank 220 as described above, the interlocking portion 269 rotates integrally with the sprocket 210 and has a large number of convex portions 273,. When the sprocket 210 rotates by contacting the contact portion 271, the height limiting member 260 vibrates. Accordingly, even if the game balls are meshed with each other between the height limiting member 260 and the bottom wall 22a of the storage tank 220 to form a bridge so that the game balls are difficult to flow, the height limiting member The bridge is broken by the vibration of 260, and the game ball can flow.

Next, a third modification will be described with reference to FIG. In the above example, the bottom portion 216 and the bottom member 218 are fixedly attached to the cylindrical body portion 201 (the main body of the storage portion 203). However, the bottom portion constituent member 219 obtained by integrally joining the bottom portion 216 and the bottom member 218 is used. It is also possible to provide a state in which the cylindrical member 201 (the main body of the storage unit 203) can be moved up and down, and the bottom component member 219 is biased upward by biasing means such as a spring.
For example, as shown in FIG. 22, in the screw hole through which the screws are inserted into the plurality of fixing pieces 311,... Provided on the outer peripheral portion of the bottom component member 219 (bottom member 218) at intervals in the circumferential direction. Instead, an insertion hole into which a slide boss 317,.

On the other hand, slide bosses 317,... That are inserted through the insertion holes of the fixed pieces 311,... Are formed at the distal ends of the fixed bosses 312. To do. In order to determine the lower limit position of the bottom component member 219 after attaching the bottom component member 219 to the cylindrical body 201 so that the slide bosses 317,... Are fixed to the lower end of the sliding boss 317 with screws 319.
As a result, the fixed pieces 311,... Can move up and down along the slide boss 317, and the bottom component member 219 can move up and down. Further, a coil spring (biasing means 320) serving as a compression spring is disposed between the washer 318 and the fixed pieces 311,... Energize to. Therefore, normally, the bottom component member 219 is located at the highest position within a range in which the bottom component 219 can move up and down by the biasing force of the biasing means 320.

In addition, it is preferable that the vertical movement range of the bottom component member 219 is less than the radius of the game ball, and is less than or equal to a fraction of the radius of the game ball. Further, when the bottom component 219 is positioned at the top, the distance between the upper surface of the bottom 216 and the lower surface of the sprocket 210 is, for example, a distance slightly shorter than the radius of the game ball.
In the unlikely event that the game ball is sandwiched between the periphery of the outlet (the ball outlet lead portion 20b) and the teeth of the sprocket 210, the rotational force of the sprocket 210 is transmitted via the game ball. When the bottom component 219 is transmitted to the bottom component 219 and moves downward against the biasing force of the biasing means 320, the distance between the upper surface of the bottom 216 and the lower surface of the sprocket 210 is slightly larger than the radius of the game ball. Therefore, there is a high possibility that the state where the game ball is sandwiched is resolved. Therefore, even if the game ball is caught as described above, the bottom 216 is moved, so that the game ball is not caught and the game ball is caught, so that the sprocket 210 is rotated. It is impossible to prevent a situation in which the discharge device 200 becomes nonfunctional.

  Here, if the bottom component member 219 moves beyond the radius of the game ball, the distance between the upper surface of the bottom portion 216 and the lower surface of the sprocket 210 may be greater than the diameter of the game ball. When the distance between the upper surface of the bottom portion 216 and the lower surface of the sprocket 210 is equal to or greater than the diameter of the game ball, the lowermost game ball of the ball receiving recesses 208,. Since it enters between the upper surface of 216 and the lower surface of the sprocket 210, the vertical movement range of the bottom component member 219 needs to be less than the radius of the game ball. Further, the vertical movement range of the bottom component member 219 needs to be a distance such that the distance between the upper surface of the bottom portion 216 and the lower surface of the sprocket 210 is larger than the radius of the game ball.

  Further, by increasing the distance between the upper surface of the bottom 216 and the lower surface of the sprocket 210, the sprocket 210 can be moved up and down in order to prevent the game ball from being caught. It is good also as a structure biased to a position, and you may combine the structure which can move the sprocket 210 up and down, and the structure which can move the bottom part 216 up and down.

The distance between the lower surface of the sprocket 210 and the upper surface of the bottom portion 216 is at least slightly smaller than the radius of the game ball when the sprocket 210 is movable up and down and when both the sprocket 210 and the bottom portion 216 are movable up and down. It is preferable that the distance is short and slightly longer than the radius of the game ball.
The sprocket 210 can be moved up and down. For example, the sprocket 210 and the rotating member upper member 214 can be moved up and down with respect to each other, for example, one of the sprocket 210 and the rotating member upper member 214. A member that guides mutual vertical movement and prevents mutual rotation, such as forming an insertion hole into which the shaft part is extended and the shaft part can be inserted into the other, is provided. Further, as an urging means for urging the sprocket 210 and the rotating member upper member 214 so as to be separated from each other vertically, for example, a compression spring is disposed between the sprocket 210 and the rotating member upper member 214. The body member 214 may be fixed to the rotation shaft of the stepping motor 204.
From the above, in the third modified example, the sprocket 210 can be moved up and down or the bottom portion constituting the bottom portion 216 so that the gap between the lower surface of the sprocket 210 and the upper surface of the bottom portion 216 can be larger than normal. The component member 219 is configured to be movable up and down.

  The gaming machine 100 of the present embodiment as described above includes a storage tank 220 that stores game balls supplied from the outside, and a game ball that is provided integrally with the storage tank 220 and stored in the storage tank 220. And a discharge device 200 that can discharge on the downstream side. The discharge device 200 is configured to be rotatable about a rotation axis set in the vertical direction and receives a plurality of game balls. The sprocket 210 having the ball receiving recesses 208,... And the outlet for discharging the game balls from the ball receiving recesses 208,... The sprocket 210 can receive a plurality of game balls in the vertical direction in each of the ball receiving recesses 208,... , And by rotating the sprocket 210, the game balls are received at the top of the ball receiving recesses 208,... And the game balls at the bottom are led out. .. Are formed on the rotation path of the game ball received in the recesses 208... And the sprocket 210 is arranged so that a gap is formed between the lower surface of the sprocket 210 and the upper surface of the bottom portion 216. .

Therefore, since the discharge device 200 is integrally provided in the storage tank 220, it is possible to reduce the installation space compared to the case where these are installed separately, and to solve the space problem on the back side of the gaming machine. Become.
Further, the rotation axis of the sprocket 210 having the ball receiving recesses 208,... Is set in the vertical direction, and the sprocket 210 is disposed horizontally so that the ball receiving recesses 208,. Thus, the game balls in the storage tank 220 or the game balls flowing down from the storage tank 220 can be smoothly discharged downward.

Further, the sprocket 210 is configured so that a plurality of game balls can be received vertically in each ball receiving recess 208,..., And the game ball is received at the uppermost portion of the ball receiving recess 208,. Therefore, even if an acceptance error occurs in the ball receiving recesses 208,..., The already received game balls can be discharged, and continuous discharge becomes possible. Therefore, even if the sprocket 210 is rotated at a high speed, a discharge error can be prevented.
In addition, since a gap is formed between the lower surface of the sprocket 210 and the upper surface of the bottom portion 216, a game ball is not sandwiched between the sprocket 210 and the outlet, and ball clogging due to high-speed rotation of the sprocket 210 is prevented. be able to. That is, the game balls can be discharged at high speed synergistically by the above two functions.

  Also, the outlet is a discharge outlet (discharge outlet 20a) provided with a detection sensor 217 for detecting the discharge ball, and a ball outlet for extracting the game ball of the storage tank 220 to the outside of the gaming machine. , And by changing the rotation direction of the sprocket 210, the game balls of the ball receiving recesses 208,... Can be removed from either the discharge outlet or the outlet for outlet. It is configured so as to lead out, and a lead-out port for ball removal is formed on the rotation path of the game ball.

Accordingly, the outlet port includes the outlet port for discharging and the outlet port for ball removal, and the outlet is derived from either the outlet port for discharging or the outlet port for ball removal by changing the rotation direction of the sprocket 210. Therefore, the outlet for deriving the game ball can be switched by changing the rotation direction of the sprocket 210.
That is, if the sprocket 210 is rotated in one direction (for example, clockwise), the game ball is derived from the discharge outlet, and if the sprocket 210 is rotated in the other direction (for example, counterclockwise), the outlet for ball removal is derived. The game ball can be derived from the ball, and by switching the rotation direction of the sprocket 210, it is possible to efficiently switch between discharging and ball removal.
Moreover, since the ball outlet port is formed on the rotation path of the game ball, the configuration of the ball outlet port can be simplified.
If the outlet is formed on the rotation path of the game ball, there is a possibility that the ball may be clogged. However, when removing the ball, it is not necessary to be as fast as the prize ball is discharged. It is possible to prevent the occurrence of clogging of the balls.

  Further, the ball receiving recesses 208 of the sprocket 210 are lower than the first ball receiving recess 211 and the upper first ball receiving recess 211 that receive the game balls from the introduction portion 202 for receiving the game balls of the storage tank 220. The first ball receiving recesses 211 are arranged on a circumference smaller in diameter than the circumference where the first ball receiving recesses 211 are arranged, and the game balls are led out to the outlet (the discharge outlet 20a or the ball outlet outlet 20b). The second sphere receiving recess 212, the first sphere receiving recess 211, and the second sphere receiving recess 212 are set and provided with a predetermined vertical dimension. An intermediate sphere receiving recess 213 having an inclined surface that is continuous with the inner surface of the ball receiving recess 212, and is provided to protrude outward from the outer peripheral portion of the sprocket 210 and constitutes a first ball receiving recess 211. 2nd sphere than the protruding amount of Projecting portion constituting the recess 212 of the projection amount of (teeth) is set to be smaller.

  Therefore, the ball receiving recesses 208,... Have an upper first ball receiving recess 211 that receives a game ball, and a diameter lower than the first ball receiving recess 211 and the diameter of the circumference where the first ball receiving recess 211 is arranged. Are arranged on the circumference of a small diameter, and are provided with a predetermined vertical dimension between the second ball receiving recess 212 for guiding the game ball to the outlet and the first ball receiving recess 211 and the second ball receiving recess 212. And the intermediate ball receiving recess 213 having an inclined surface continuous from the inner surface of the first ball receiving recess 211 to the inner surface of the second ball receiving recess 212, so that the sprocket 210 can be smoothly rotated. it can.

In other words, the diameter of the circumference in which the respective ball receiving recesses are arranged is formed such that the first ball receiving recess 211 is the largest, and the intermediate ball receiving recess 213 and the second ball receiving recess 212 are sequentially reduced in order. In the game balls that overlap vertically in the ball receiving recesses 208,..., The game balls that overlap the upper side overlap the outer side along the radial direction of the sprocket 210 rather than the lower game balls. As a result, the pressure in the vertical direction due to the load of the upper game ball on the lower game ball is reduced.
Since the game ball received in the intermediate ball receiving recess 213 contacts the inclined surface of the sprocket 210, the pressure due to the load of the game ball received in the first ball receiving recess 211 is dispersed and applied to the sprocket 210. The pressure in the direction of the central axis of the sprocket 210 is reduced.
Therefore, even if a plurality of game balls are received around the sprocket 210, the sprocket 210 can be smoothly rotated.

  In addition, since three game balls are received in each ball receiving recess 208,... So as to overlap each other, even if a mistake in accepting a game ball occurs, the game is not completed until the stage where the acceptance error occurs becomes the lowest stage. The possibility that the ball is replenished is high, and it is possible to prevent the discharge from being interrupted.

In addition, since the protruding amount of the protruding part constituting the second ball receiving recess 212 is set smaller than the protruding amount of the protruding part provided on the outer peripheral part of the sprocket 210 and forming the first ball receiving recess 211. The shape of the first ball receiving recess 211 that faces the introduction portion 202 that receives the game ball of the storage tank 220 can surround a wide range (for example, approximately a half circumference) of the game ball, and reliably receives the game ball. It becomes possible.
That is, when the protruding amount of the protruding portions of the ball receiving recesses 208,... Is small, there is no protruding portion between adjacent game balls, so the receiving area of the game balls becomes the adjacent game balls. In this configuration, the receiving area changes due to the movement of the game ball, and further, since there is no member between the game ball and the game ball, the unevenness on the upper surface of the sprocket 210 increases, so that the game ball jumps greatly. However, such problems can be solved, although it may hinder the acceptance of game balls.
On the other hand, by setting the protruding amount of the protruding portion constituting the second ball receiving recess 212 to be small, the contact portion with the game ball at the time of being led out to the outlet can be reduced, and the ball receiving recesses 208,. Ball clogging with the outlet can be prevented.

  Further, a stepped portion 209 is formed at the edge of the outlet (the ball outlet outlet 20b) and has a step downward from the bottom of the storage portion 203 in the direction in which the game ball enters the outlet. The dimension between the lower surface of the step and the upper surface of the step portion 209 is set larger than the radius of the game ball.

Therefore, a stepped portion 209 is formed which is provided at the edge of the outlet and has a step downward from the bottom of the storage portion 203 in the direction in which the game ball enters the outlet. The lower surface of the sprocket 210 and the upper surface of the stepped portion 209 are formed. Since the dimension between and is set to be larger than the radius of the game ball, clogging of the ball can be prevented.
That is, when the game ball reaches the stepped portion 209, the lower surface of the sprocket 210 (the lower surface of the second ball receiving recess 212) comes into contact with the upper part of the game ball and promotes the fall of the game ball. Can be prevented.

  Further, in a required range above the outlet port (discharge outlet 20a, ball outlet outlet 20a) in the side wall (cylinder body 201) of the storage unit 203, one level higher than the lowest level in the ball receiving recesses 208,. A rib 21e for preventing the game ball from flowing down to the outlet port (holding the game ball in the ball receiving recess 208,...) Is provided in the center of the sprocket 210.

  Therefore, a rib 21e is provided in the required range above the outlet in the side wall of the storage portion 203 to prevent the game ball in the upper stage of the ball receiving recesses 208, ... from flowing down to the outlet.
