Referring to FIG. 2, a card unit 3 (hereinafter also abbreviated as CU3), which is an example of a gaming device, is located one-to-one with respect to the pachinko gaming machine 2 at a predetermined lateral position of the pachinko gaming machine 2. It is installed in correspondence with. This card unit 3 is issued to a visitor card having a prepaid function which is a game recording medium issued to a general player who has not registered as a member, or to a member player who has registered as a member in the game hall. Accepting a membership card, which is a game recording medium to be played, and using the game value (for example, card balance, number of balls held, number of balls stored, etc.) owned by the player specified by the record information of those cards The pachinko gaming machine 2 has a function for allowing a game to be performed by firing and firing an encapsulated ball as an example of a game medium. The visitor card and membership card are composed of IC cards.

  The card unit 3 that has received these cards converts the game value (for example, card balance, number of balls held, number of balls stored, etc.) owned by the player specified by the record information of the card into “game ball data”. Has the function of In the pachinko gaming machine 2, a bullet ball game equivalent to the number of balls specified by the data of the game balls is made possible. That is, “game ball data” is data indicating the number of remaining fireable shots. In the following description, “game sphere data” is simply referred to as “game sphere” in the same manner as storage balls and holding balls.

  On the front side of the card unit 3, a bill insertion slot 302 for inserting bills, a protruding portion 305 formed to project forward from the front side of the device, and a card insertion / discharge port for inserting a membership card or a visitor card 309 etc. are provided. The member card or visitor card inserted into the card insertion / discharge port 309 is received by a card reader / writer (not shown), and information recorded on the card is read.

  In the protrusion 305 described above, on the surface facing the player, the display 312 and the membership card ID recorded on the membership card (also simply referred to as the card ID) and the membership card when the membership card is received. An infrared signal is received by an IR (Infrared) photosensitive unit 320 from a replay button 319 for executing a replay game using the number of stored balls specified by the ID and a remote control (not shown) possessed by an attendant of the game hall. Thus, an IR light receiving unit that converts the electronic signal into an output is provided.

  The display 312 displays a prepaid balance (also referred to as a card balance or simply a balance) recorded on the inserted game recording medium (card), but other numbers such as the number of game balls and error information to be described later are also displayed. Various types of information can be displayed, and the surface is configured with a transparent touch panel. Various types of operations can be input by touching various display items displayed on the display unit of the display 312 with a finger. ing.

  When the replay button 319 is operated, if the number of possessed balls acquired by the player is recorded on the inserted card, a part of the possessed number is withdrawn and converted into a game ball, and the converted game ball Based on the above, it becomes possible to play a game with the pachinko gaming machine 2. On the other hand, if the inserted card is a membership card and the number of balls is not recorded, and the stored ball is recorded in the hall management computer, etc., a part of the stored ball is withdrawn and the game ball Is converted into a game, and a game by the pachinko gaming machine 2 becomes possible. That is, when both the stored ball and the holding point are stored in association with the inserted card, the holding ball is withdrawn preferentially. In addition to the replay button 319, a dedicated ball payout button for withdrawing the ball may be provided, and the replay button 319 may be a dedicated button for saving the ball.

  Here, “storing” is a game medium deposited in a game hall, and is generally managed by a hall management computer or other management computer installed in the game hall.

  “Number of possessed balls” means the number of game balls owned by a player as a result of a player playing a game with a gaming machine on a card, and the number of balls not yet deposited in the game hall That's it. In general, the number of balls acquired by a player on the day of the game hall is called “held ball”, and the number of balls acquired by the player before the previous day and stored in the game hall is expressed as “stored ball”. "

  The “game ball” is data on the number of balls that can be launched by the game machine. As described above, this data is generated in exchange for withdrawing the balance of the prepaid card, the holding ball, or the stored ball.

  The number of balls may be managed by a management device for managing the number of balls set in the game hall. In short, the difference between “storing” and “holding” is the number of balls stored in the amusement hall after a storage operation for depositing in the amusement hall, or is still in the amusement park. It is a point whether it is the number of balls of the stage which is not put.

  In this embodiment, the stored ball data is not recorded directly on the membership card, but is stored in association with the membership card number in a hall server installed in a game hall such as a hall management computer, and the corresponding storage data is based on the membership card number. It is configured to search for spheres. On the other hand, the ball is directly recorded on the card. However, the present invention is not limited to this, and both may be stored in the hall server in association with the card number. In the case of a visitor card, the ball is recorded directly on the visitor card. However, the present invention is not limited to this, and the holding ball may be stored in the hall server in association with the card number. When storing in the hall server in association with the card number, data that can specify the time stored in the hall server may be written in the card (member card, visitor card) and discharged. Also, the prepaid balance is directly written on a card (member card, visitor card) and discharged.

  The timing for storing the ball in the card (member card, visitor card) or hall server is stored in real time every time the counting button 28 (see FIG. 23) is operated and the counting process is performed. For example, they may be stored at regular intervals, or may be stored in a lump when cards are returned. The banknote inserted into the banknote insertion slot 302 is taken in by a currency discriminator (not shown), and its authenticity and banknote type are identified.

  A ball lending button (also referred to as a lending button) 321 and a return button 322 are further provided on the front side of the card unit 3. The ball lending button 321 is a button for performing an operation (conversion operation to a game ball) for withdrawing the balance recorded on the inserted card and using it for a game by the pachinko gaming machine 2. The return button 322 is operated when the player ends the game, and the number of game balls determined at the end of the game on the inserted card (number of balls held at the time of card insertion-number of conversions to game balls + counting operation) This is an operation button for storing and discharging the number of possessed balls counted by. The return button 322 may be provided in the gaming machine, and the signal itself when the return button 322 is operated may be input to the card unit.

  With further reference to FIG. 2, below the game area 27 and the out port 61 on the front (front) side of the pachinko gaming machine 2, there are a polishing device 23 for polishing the surface of the game ball, a surplus ball hole 66, A surplus sphere path 67, a surplus sphere path outlet 68, a surplus sphere stop 69, and the like are arranged. The polishing apparatus 23 is a part of the circulation path of the game balls, and the surplus ball hole 66, the surplus ball path 67, the surplus ball path outlet 68, and the surplus ball stop 69 are areas connected to the circulation path. . These will be described in detail later.

  Referring to FIG. 3, on the back side of the pachinko gaming machine 2, the main control board 16, the payout control board 17, the power supply device 21, the conveying screw 72, the ball lifting device 25, the launching device 14, Are arranged, and these are surrounded by the outer frame 6. The main control board 16 is provided on the game board 26 and controls the progress of the game of the pachinko gaming machine 2. The payout control board 17 and the power supply device 21 are arranged on the rear side (front side of the pachinko gaming machine 2) shown in the lower left of FIG. 3 and are provided so as to be fixed to the gaming machine frame 4. The payout control board 17 manages and stores game balls. As will be described later, the conveying screw 72 is a part of the polishing apparatus 23 and a part of the circulation path. The conveying screw 72 conveys the game ball to be polished while circulating. The ball lifting device 25 is a device that transports (lifts) the game ball to the upper side of the pachinko gaming machine 2, and is a part of the circulation path. The launching device 14 is disposed above the pachinko gaming machine 2 and is a device that launches a game ball toward the game area 27 for gaming. The launcher 14 is also part of the circulation path. As described above, the circulation path of the game balls in the present embodiment is basically the position of the pachinko gaming machine 2 that goes around the pachinko machine 2 so as to include the polishing device 23, the ball lifting device 25, and the launch device 14 ( For example, the route is configured to return to the launch position of the launch device 14. In addition to the above members, the game area 27 may be considered as a circulation path (see FIG. 7).

  FIG. 4 is an enlarged cross-sectional perspective view showing in detail the cross-sectional aspect of the region including the out port 61 and the surplus ball hole 66 and the like, and shows the flow of the game ball coming out of the game region 27. In FIG. 4, the front (right front side) is the front side of the pachinko gaming machine 2. Referring to FIG. 4, as described above, the game balls (game balls) 10 that have been put into the game area 27 for the game are not won (referred to as out balls) through the out port 61 in the drawing. Falls in the direction indicated by the arrow and reaches the filling space 63 including the ball guiding path below the game area 27. The out ball collected from the out port 61 is detected by an out ball detection switch 88, and the detection signal is input to a payout control unit 171 described later.

  On the other hand, a winning thing (referred to as a winning ball or a safe ball) in any winning opening falls, for example, through the winning ball path 62 in the direction indicated by the arrow in the drawing and reaches the filling space 63. If the polishing entrance ball detection switch 701 detects that the game ball P has started to reach the filling space 63 after the game is started, the polishing motor 71 of the polishing device 23 constituting the circulation path starts to be driven. The game ball can be transferred.

  However, the circulation path may be set so that the circulation of the game ball is started by starting driving when the polishing entrance ball detection switch 701 detects that the game ball has started to be inserted as described above. However, as a modification, even if the sensors (polishing entrance ball detection switch 701 and the first fullness detection sensor 75 and the second fullness detection sensor 40 described later) provided in the circulation path do not detect any game balls, the pachinko game The specification may be such that the operation of circulating the game ball continuously from when the machine 2 is turned on.

  However, the number of game balls (for example, game balls thrown in from the out port 61) trying to enter the filling space 63 may be excessive with respect to the number of game media that can be stored in the filling space 63. For example, when the filling space 63 can store 40 game balls, if 40 game balls enter the filling space 63, the filling space 63 fills up to the uppermost portion 64 of the filling space and becomes full. It is in a state. After this state is reached, the game balls (41st and later) trying to enter the filling space 63 overflow from the filling space 63, and therefore enter the surplus ball hole 66 immediately above the uppermost portion 64 of the filling space. .

  Referring to FIG. 5, the surplus (for example, the 41st and subsequent) game balls that have advanced toward surplus ball hole 66 are connected from surplus ball hole 66 and provided in front of filling space 63. The extra ball path 67, which is the flow path for the game balls, is guided from the extra ball path outlet 68 to the extra ball stop section 69 and stored in the extra ball stop section 69. That is, the surplus ball stop 69 is disposed at a predetermined position on the front side of the pachinko gaming machine 2.

  A front portion of the door covering surface 65 is covered with the lower door frame 12 provided with the indicator 54, the hitting operation handle 13 and the like shown in FIG. 1, and the surplus ball stopping portion 69 and the like are also covered with the lower door frame. 12 is covered. The lower door frame 12 is normally locked (locked) by a key possessed by an attendant at the game hall, and cannot be unlocked by the player but can be unlocked and opened by the attendant at the game hall. For this reason, the player cannot take out the game balls stored in the surplus ball stopping portion 69 by himself / herself, and can take out only the staff in the game hall. The clerk at the game hall can take out the game balls stored in the surplus ball stop 69 to discharge the game balls stored in the surplus ball stop 69 to the outside of the pachinko gaming machine 2. For example, if the surplus ball retaining portion 69 is disposed at a position that is exposed when the portion where the indicator 54 of FIG. 1 is installed is opened, the game can be achieved simply by opening the portion where the indicator 54 of FIG. 1 is installed. The ball can be easily taken out. The surplus ball stop 69 may be provided on the front side (player side) of the lower door frame 12.

  As shown in FIG. 5, the game ball that overflows from the full filling space 63 and flows from the surplus ball hole 66 toward the surplus ball retaining portion 69 uses, for example, gravity without using driving force. Thus, it is configured to naturally flow from the surplus sphere hole 66 toward the surplus sphere stop 69. For this reason, it is not necessary to additionally provide a member used as a driving force for guiding the game ball toward the surplus ball stopping portion 69, and the configuration of the equipment can be simplified.

  In addition, since the surplus game balls guided to the surplus ball stop section 69 can be easily taken out by the staff of the game hall, the surplus ball stop section 69 is used not only as a place for storing the surplus game balls but also as a service ball. It can be shared as a place to store game balls. For this reason, space saving can be achieved compared with the case where the surplus ball stopping part 69 and the service ball storage location are provided as separate locations.

  Further, for example, once the game balls in the pachinko gaming machine 2 are taken out (extracted) for maintenance, the power is turned on and the game balls are put into the pachinko gaming machine 2 again (for example, the out port 61). When the game balls are supplied from the out port 61 to the circulation path, the number of balls that can be stored in the entire circulation path of the pachinko gaming machine 2 is determined to be a predetermined number (for example, 40). Furthermore, the game balls in the filling space 63 are filled when exactly 40 are supplied. Then, the number of game balls exceeding 40 overflows from the filling space 63 and starts to flow into the surplus ball stop 69. As a result, it can be easily confirmed that the supply of the required number (40) of game balls to normally circulate the game balls in the circulation path of the pachinko gaming machine 2 is completed. In addition, since the surplus game balls are naturally moved toward the surplus ball stop 69, it is not necessary to accurately count the number of game balls when they are thrown into the pachinko gaming machine 2. A game ball can be thrown into. For this reason, a predetermined number of game balls can be easily thrown into the pachinko gaming machine 2 (circulation path).

  In addition, since a predetermined number of game balls can be easily thrown into the pachinko gaming machine 2 as described above, for example, even when the launching device 14 is above the pachinko gaming machine 2 as in this embodiment, A prescribed number (for example, 40) of game balls can be easily supplied to the entire circulation path including the device 14.

  FIG. 6 is an enlarged view of the polishing device 23 attached to the pachinko gaming machine 2 as viewed from the back side of the pachinko gaming machine 2. Actually, the back side of the transport screw 72 is covered with a cover. The cover is omitted in order to make the conveying screw 72 easier to see.

  As shown in FIG. 6, for example, a game ball moved from the filling space 63 enters the polishing start end portion 78 of the transport screw 72 through a generally known passage or the like. Here, when a game ball enters the polishing start end 78 of the conveying screw 72 in a state where the polishing cassette 73 is set to face the front surface of the conveying screw 72, the game ball is in contact with the polishing start end 78 and the polishing cassette. 73 so as to be sandwiched between the polishing members in 73. The polishing motor 71 is driven on condition that a game ball is detected by a polishing inlet ball detection switch 701 (also referred to as a polishing inlet ball detection switch) and a first full detection sensor 75 described later does not detect the full state of the ball. Begin. The driving of the polishing motor 71 is controlled by the dispensing control board 17 described above. When the polishing motor 71 is driven, the motor gear provided in the polishing motor 71 rotates, so that the conveying screw 72 fixed to the gear connected to the motor gear starts to rotate. In particular, when using a polishing member that constantly moves, the polishing member may also start to drive as described above.

  The surface of the game ball that comes into contact with the rotation of the conveying screw 72 is polished while being conveyed toward the polishing end end 79 which is the other end of the conveying screw 72 (the other end relative to the polishing start end 78). Polishing is performed by the member to remove the dirt on the surface.

  Further, in the vicinity of the polishing device 23 (here, the polishing end portion 79) (the back side of the pachinko gaming machine 2), a first full detection sensor 75, a ball hole 76, and a ball hole cover (not shown). ) And are arranged. The 1st fullness detection sensor 75 is a sensor which detects that the game ball arrange | positioned at a part of circulation path (especially 1st fullness detection sensor 75 is arrange | positioned, the movement lower side of the grinding | polishing apparatus 23) was filled. The first fullness detection sensor 75 also functions as a sensor that detects that a game ball has started to be thrown into the ball lifting device 25 when the game is started. That is, the first fullness detection sensor 75 detects that the game ball has started to enter the area of the first fullness detection sensor 75 and the second fullness detection sensor 40 does not detect the full state of the ball. The function of starting the driving of the ball lifting device 25 and the fact that the game ball is full is detected and the driving of the polishing motor 71 is stopped, so that no more game balls are sent to the moving lower side of the polishing device 23. Combined with function.

  In other words, the polishing motor 71 and the conveying screw 72 until the first full detection sensor 75 detects that the game ball is full after the polishing motor 71 starts driving (while it is not detected). The driving ball moves from the polishing start end portion 78 toward the polishing end portion 79 by the driving of. That is, there is provided stop means for stopping the driving of the polishing motor 71 when the first full detection sensor 75 detects that the game ball is full in the polishing apparatus 23. When the first fullness detection sensor 75 detects the insertion of the game ball P, the lifting motor of the ball lifting device 25 constituting the circulation path starts to be driven, and the circulation path causes the game ball to move toward the ball lifting device 25. It can be transferred to

  The ball hole 76 is a discharge port for discharging a game ball arranged inside the circulation path to the outside of the pachinko gaming machine 2 during maintenance, for example. Accordingly, an operation of discharging the game ball from the ball punch hole 76 during the normal game operation may be performed, but an operation of discharging the game ball from the ball punch hole 76 after setting the pachinko gaming machine 2 to the maintenance mode. May be made. For example, when the game ball is discharged from the ball hole 76 after setting the maintenance mode, the control for discharging the game ball at a higher speed than when the game ball is discharged from the ball hole 76 during a normal game operation is performed. By performing the above, it is possible to speed up the operation of discharging the sphere. This is because by setting the maintenance mode, the payout control unit 171 drives and controls the polishing motor 71 and the lifting motor 93 at a high speed different from that during normal gaming.

  The ball hole cover (not shown) is, for example, a cover that covers the discharge port so that the game ball is not discharged from the ball hole 76 during normal use. For example, when an attendant at a game hall attaches or removes a ball hole cover (not shown), the ball hole 76 is opened and the ball can be discharged, and the ball hole is discharged. The hole cover (not shown) is closed, the ball hole 76 is closed, and it is possible to freely switch between a closed state where the game ball is not discharged.

  The ball hole 76 and the ball hole cover (not shown) are provided in the vicinity of the polishing end portion 79 of the polishing apparatus 23. That is, the game ball discharged from the ball punching hole 76 can have a clean surface immediately after being polished by the polishing device 23 (immediately after passing through the polishing device 23).

  By opening the ball hole cover (not shown), a game ball that is not subject to any restraint within the pachinko gaming machine 2 including the circulation path, for example, falls naturally by the action of gravity, The ball can be discharged from the ball hole 76 to the outside of the pachinko gaming machine 2. Since the above-mentioned game balls that fall naturally are discharged naturally without receiving any driving force, it is possible to discharge the game balls more easily (by a simple method).

  However, for a game ball that is mechanically restrained inside the pachinko gaming machine 2, such as a game ball that is sandwiched between the conveying screw 72 and the polishing member of the polishing apparatus 23 and is being polished, a ball removal operation button ( The ball is discharged from the ball extraction hole 76 by the action of an automatic operating means (not shown) that operates by pressing a not shown.

  Here, for example, if a ball hole cover (not shown) is provided at the lowest point of the circulation path, no member is restrained when the ball hole cover (not shown) is opened. The number of game balls that can be discharged from the ball punching hole 76 is increased by naturally falling due to the action of gravity. For this reason, the efficiency of discharging the game ball can be further increased. Therefore, it is more preferable that the ball hole 76 and the ball hole cover (not shown) are provided below the pachinko gaming machine 2.

  As shown in FIGS. 6 and 7, a ball lifting device 25 extends in the vertical direction on the right side of the back surface of the pachinko gaming machine 2, that is, on the left side when the pachinko gaming machine 2 is viewed from the front. The game ball moved from the polishing end portion 79 enters the ball lifting device 25.

These drive gears (not shown) and driven gears (not shown) are linked via a plurality of idle gears (not shown).

  The operation of a lifting motor 93 that drives the drive gear (not shown) and the driven gear (not shown) is controlled by a launching and lifting control unit (not shown), so that a game ball P from the launching device 14 is obtained. The game ball P is lifted and supplied by the ball lifting device 25 in conjunction with the launch.

  As described above, the ball feed rotating body 205 is synchronized with a driven gear (not shown) that meshes with a drive gear (not shown) that is rotated by the lifting motor 93 that rotates the lifting screw body 206 via the idle gear. It is provided to rotate. The gear ratio between the driving gear (not shown) and the driven gear (not shown), that is, the gear ratio between the lifting screw body 206 and the ball feeding rotary body 205 is variously changed according to the lifting distance of the balls. Is possible.

  A guide passage 204 that guides the game ball P from the right lifting ball inlet 203 toward the left lifting portion 202 extends from the rear portion of the base member 220. The guide passage 204 is formed in a substantially upward U shape in a longitudinal sectional view by an upper surface of the base member 220, and a front wall portion 204A and a rear wall portion 204B standing on the upper surface of the base member 220. Abbreviation).

  The guide passage 204 includes a curved portion 224 that guides the game ball P that has entered from the lifting ball entrance 203 toward the left diagonal front side and then guides it to the diagonal left rear side. The upstream side of the curved portion 224 on the upper surface of the base member 220 is an inclined surface that is inclined downward toward the guiding direction of the game ball P, and guides the game ball P by natural flow.

  In the guide passage 204, on the downstream front side of the curved portion 224, a ball feed rotating body 205 that sends the game ball P flowing down the guide passage 204 to the lifting section 202 by rotation, a part of the outer peripheral surface 205 A of the guide passage 204 is provided. It is provided so as to be rotatable about a rotation shaft 223 orthogonal to the bottom surface of the guide passage 204 so as to constitute the front wall portion. More specifically, the ball feed rotating body 205 sends the game ball P that has flowed down the guide passage 204 to the lift position Y (see FIG. 11A) where the game ball P is scooped up by the lift screw body 206. It arrange | positions so that the game ball P following P may be controlled in the control position K (refer FIG. 11 (A)).

  As shown in FIG. 12, a substantially semicircular ball housing recess 230 that can accommodate the game ball P that is allowed to flow down at the restriction position K in the guide passage 204 on the outer circumferential surface 205 </ b> A of the ball feed rotating body 205. An (engagement recess) is provided, and the ball housing recess 230 has a depth to which a half of the game ball P is engaged. In addition, the radius on one end side (rear side in the rotation direction) of the ball receiving recess 230 in the ball feed rotating body 205 is a radius R1, whereas the radius on the other end side (front side in the rotation direction) of the ball receiving recess 230 is The radius R2 is shorter than the radius R1 (R1> R2), and is formed so that the radius R2 gradually approaches the radius R1 in the rotational direction.

  That is, an engagement guide portion 231 whose radius gradually decreases toward the ball receiving recess 230 is formed on the outer peripheral surface 205A of the ball feeding rotary body 205, and the outer peripheral surface 205A is formed by the engagement guide portion 231. The game ball P in contact with the ball can be gradually brought closer to the rotation shaft 223 and engaged with the ball housing recess 230. On the other hand, a ball feeding surface 230B is formed along the straight line passing through the rotation shaft 223 on the side opposite to the engagement guide portion 231 in the ball receiving recess 230, and the game ball P received in the ball receiving recess 230 is It is designed to feed in the direction of rotation.

  As shown in FIGS. 8 to 10, on the rear side of the ball feed rotator 205, a turntable 222 that can rotate around a drive shaft 93 </ b> A orthogonal to the bottom surface of the guide passage 204 is attached to the ball feed rotator 205. Proximity is provided. On the upper surface of the turntable 222, a cylindrical protrusion 241A that covers the upper end of the drive shaft 93A that protrudes upward through the turntable 222, and a straight line that is formed along a straight line that passes through the drive shaft 93A. A projecting portion 241B is formed in a projecting manner (see FIG. 10A), and a lower end of a lifting screw body 206 described later is fitted into the projecting portions 241A and 241B. .

  The left and right sides and the rear side of the turntable 222 are covered by a wall 240A, and the front side protrudes toward the front side so as to be positioned above the ball feed rotating body 205, and the lower portion of the feed passage 210 is formed. It is covered with a wall 240B having a substantially J shape in plan view.

  A cutout 240C is formed at a position corresponding to the guide passage 204 on the right side of the wall 240B, so that the game ball P sent out by the ball feed rotating body 205 can enter the lifting passage 210. A region surrounded by the wall 240B is a lifting position Y where the game ball P is scooped and lifted by the lifting screw body 206.

  In addition, at a position corresponding to the ball feed rotating body 205 in the guide passage 204, a slope-shaped guide inclined surface 250 that gradually slopes upward from the position near the upstream side of the notch 240C toward the lift position Y is provided as a ball feed. An arc shape is formed along the periphery of the rotating body 205. A part of the guide inclined surface 250 is disposed below the passing position through which the ball feed surface 230B passes when the ball feed rotating body 205 rotates, and the game ball P sent out by the ball feed surface 230B is gradually raised. Then, it is guided to the lifting position Y that is lifted by the lifting screw body 206.

  A rotating body 260 made of a polyacetal resin material is provided at a corner of the curved portion 224 of the guide passage 204 on the rear wall portion 204B side so as to be rotatable about a rotation shaft 261 orthogonal to the bottom surface of the guide passage 204. Yes. As shown in FIGS. 10B and 10C, the rotating body 260 is rotatably provided to the rotating shaft 261 via a bearing 262, and the outer periphery of the rotating body 260 is formed from a gap formed in the rear wall portion 240B. A part of the surface 260A is arranged so as to be exposed to the guide passage 204 side and constitutes a part of the rear wall part 240B.

  More specifically, the guide passage 204 includes a first passage portion (upstream portion) for guiding the game ball P that has entered from the lifting ball entrance 203 toward the ball feed rotator 205, and the ball feed rotator 205 from the first passage portion. A second passage portion (downstream portion) having an arc shape in plan view extending along the outer peripheral surface 205A. The rotating body 260 has a corner of the rear wall portion 204B that is a position facing the ball feed rotating body 205 at a curved portion 224 between the first passage portion (upstream portion) and the second passage portion (downstream portion). In the rear wall 240B, at the corner between the wall H1 facing forward and the wall H2 facing diagonally to the left, it is guided to the opposite position facing the ball feed rotator 205 across the guide passage 204. An outer peripheral surface 260A is disposed so as to be able to come into contact with the game ball P of the passage 204, and is a free roller that rotates by contact with the game ball P.

  In the present embodiment, the rotating body 260 is made of a polyacetal resin material having excellent mechanical strength and good wear resistance and sliding resistance, so that it is damaged by contact with the game ball P. It is difficult, and when it comes into contact with the game ball P, it can be smoothly sent out in the guiding direction, but the present invention is not limited to this, such as resin or metal material other than polyacetal resin material, etc. It may be composed of other materials.

  In this embodiment, the rotating body 260 is rotatably supported with respect to the rotating shaft 261 via the bearing 262. However, the present invention is not limited to this, and the rotating body 260 is not limited to the bearing 262. The shaft 261 may be pivotally supported so as to be slidable directly. Further, the rotating body 260 does not have to be pivotally supported around the rotating shaft 261 as long as the rotating body 260 is provided so as to be rotatable around at least an axis orthogonal to the bottom surface of the guide passage 204.

  Next, the situation where the game ball P guided by the guide passage 204 is sent out to the lifting position Y will be described with reference to FIGS. 11 and 12. As shown in FIGS. 11 (A) and 12 (A), a plurality of game balls P (hereinafter referred to as game balls P1 to P4) that have entered the guide passage 204 from the lifting ball entrance 203 are guided by the guide passage 204. It is induced by natural flow due to the inclination of the bottom surface on the upstream side. When the ball housing recess 230 is in a position not corresponding to the guide passage 204, the separation dimension S1 between the outer peripheral surface 205A of the ball feed rotating body 205 and the outer peripheral surface 260A of the rotating body 260 is shorter than the diameter 2R of the game ball P. Therefore (S1> 2R), the leading game ball P1 is restricted from moving to the lifting position Y side by contacting the outer peripheral surface 205A of the ball feed rotating body 205 and the outer peripheral surface 260A of the rotating body 260. . Further, by being pressed by the subsequent game balls P <b> 2 to P <b> 4, the ball is pressed against the outer peripheral surface 205 </ b> A of the ball feed rotating body 205 and the outer peripheral surface 260 </ b> A of the rotating body 260, so that the restriction position K is maintained.

  When the lifting screw body 206 is rotated in the first direction (clockwise in plan view) together with the rotating disk 222 (see FIG. 9) by the lifting motor 93, the ball feeding rotating body 205 is rotated in the second direction in synchronization with the rotation of the rotating disk 222. Rotate in the direction (counterclockwise in plan view). Accordingly, as shown in FIG. 12A, a rotational force in the first direction is applied to the game ball P1 that is in contact with the outer peripheral surface 205A of the ball feed rotary body 205, but the rotary body 260 becomes a game ball. By rotating in the second direction by the rotational force of P1, it is difficult for friction to occur at the contact portion with the outer peripheral surface 260A of the rotating body 260, so that a load is not generated in the rotation of the ball feed rotating body 205.

  Next, as shown in FIGS. 11B and 12B, when the engagement guide portion 231 moves toward the position corresponding to the guide passage 204, the separation dimension S2 gradually increases. The game ball P1 at the restriction position K is pressed against the outer peripheral surface 205A by the ball pressure of the subsequent game balls P2 to P4 and gradually moves toward the rotating shaft 223 while rotating.

  11C and 12C, when the ball housing recess 230 moves to a position corresponding to the guide passage 204, the separation dimension S3 is larger than the diameter of the game ball P. Thus, the movement restriction by the ball feed rotating body 205 is released, and the ball feed recess 230 is entered.

  Next, as shown in FIG. 11D, the game ball P1 that has entered the ball housing recess 230 is sent out toward the lifting position Y by the ball feed surface 230B. At this time, when the game ball P1 comes into contact with the rotating body 260, the rotating body 260 rotates in the first direction, so that the game ball P1 is smoothly sent out toward the lifting position Y side. Further, since the movement of the subsequent game ball P2 is restricted at the restriction position K by the outer peripheral surface 205A of the ball feed rotating body 205, only the game ball P1 is sent out to the lifting position Y.

  As shown in FIG. 11 (E), the game ball P1 is guided upward by the guide inclined surface 250 while being sent out by the ball feed surface 230B. And it enters into the lifting position Y which is the lower position of the lifting passage 210 surrounded by the wall 240B through the notch 240C from the side. Here, as shown in FIG. 11 (F), the game ball P1 is scooped up by the lifting screw body 206, and is lifted upward by the lifting screw body 206. During this time, the ball feed rotating body 205 continues to rotate, and next, the game ball P2 enters the ball housing recess 230 and is sent out to the lift position Y by the ball feed surface 230B. In this way, each time the ball feed rotator 205 makes one round, the game balls P in the guide passage 204 are sent one by one to the lifting position Y and are lifted.

  Here, as shown in FIG. 11D, when the ball housing recess 230 rotates to the position corresponding to the guide passage 204 and the game ball P1 is sent to the lifting position Y side by the ball feed surface 230B, for example, As shown in FIG. 12D, the game ball P1 may be sandwiched between the tip of the ball feed surface 230B and the outer peripheral surface 260A of the rotating body 260. Specifically, when the straight line T connecting the contact point T1 with the ball feed rotator 205 and the contact point T2 with the outer peripheral surface 260A of the rotator 260 passes through the center point O of the game ball P1, the ball biting is performed. There is a possibility that the rotation of the ball feed rotating body 205 is stopped.

  However, since the rotating body 260 is rotatably provided, as shown in FIG. 12E, the rotating force is pushed by the force pushed to the lifting position Y side by the ball feeding surface 230B acting on the game ball P1. As the body 260 rotates in the first direction, the game ball P1 is smoothly delivered to the lifting position Y side. In particular, if the center point O of the game ball P1 is slightly shifted from the straight line T to the lift position Y side, the game ball P1 is likely to be sent to the lift position Y side. Further, in the state shown in FIG. 12D, the game balls P1 are given the ball pressures of the subsequent game balls P2 to P4, which makes it easier for the rotating body 260 to rotate in the second direction. Biting is less likely to occur.

  In the state shown in FIG. 12D, when the center point O of the game ball P1 is slightly shifted from the straight line T toward the restriction position K, as shown in FIG. 12F, the game ball P1 When the rotating body 260 rotates in the second direction due to the force that pushes out the ball toward the restriction position K, the game ball P1 is smoothly sent out toward the restriction position K. In this case, the game ball P1 is not lifted, but if the ball feed rotating body 205 continues to rotate, it will be sent to the lift position Y by the ball receiving recess 230 after the next time.

  As described above, since the rotating body 260 is provided at the position opposite to the ball feed rotating body 205 in the guide passage 204, the game ball P1 is sandwiched between the ball feeding rotating body 205 and the rotating body 260. Since the rotating body 260 rotates in the lifting position Y direction or the restricting position K direction, it becomes difficult for friction to occur between the outer peripheral surface 260A of the rotating body 260 and the outer peripheral surface of the game ball P1, so that the ball feeding rotating body It is possible to suitably suppress the occurrence of the biting of the ball in the vicinity of 205 and the gaming ball P not being sent out to the lifting position Y.

  Next, the details of the lifting unit 202 will be described with reference to FIGS.

  As shown in FIGS. 13 and 20, the lifting case body 208 includes a first case 271 and a second case 270 supported so as to be openable and closable around the left side of the first case 271. The lower end portion of the first case 271 is attached to the upper portion of the wall portions 240A and 240B of the ball delivery mechanism portion 201 (see the two-dot chain line in FIG. 8), and the upper end portion is attached to a predetermined position on the back surface of the gaming machine frame 4. The pachinko gaming machine 2 is provided on the back surface. Although the first case 271 is formed of a non-translucent synthetic resin material, the second case 270 is formed of a translucent synthetic resin material, so that the second case 270 is formed. The lifting screw body 206 and the game ball P inside the lifting case body 208 can be seen from the outside of the lifting case body 208.

  The second case 270 includes an upper case 270H and a lower case 270L, and is supported so as to be able to be opened and closed independently of the first case 271. In addition, when the first case 271 is closed by the second case 270, the lower part of the upper case 270H is locked by the upper part of the lower case 270L so that the upper case 270H cannot be opened unless the lower case 270L is opened. It is configured.

  The inner peripheral surface 270A of the second case 270 is formed in a semicircular cross-sectional shape, and a concave groove 272 extends in the vertical direction at the rear portion of the inner peripheral surface 270A, so that the concave on the outer surface of the second case 270 is formed. A protruding strip 273 projecting backward is extended in a vertical direction at a location corresponding to the groove 272, and the strength of the second case 270 is improved by the protruding strip 273. A plurality of plate-like ribs 274 are provided in the concave groove 272 at a plurality of locations, and the front surface 274E of the rib 274 is formed in an arc shape to constitute a part of the inner peripheral surface 270A. .

  In addition, press portions 275A to 275D for pressing a feeding screw body 206, which will be described later, are formed at a plurality of locations in the vertical direction at the central portion in the vertical direction on the inner peripheral surface 270A. The front surfaces 275E of the presser portions 275A to 275D are formed in a semicircular arc shape, and are particularly formed to protrude inward with respect to the inner peripheral surface 270A and the front surface 274E of the rib 274. The vertical dimensions of the presser portions 275A to 275D are different from each other.

  The inner peripheral surface 271A of the first case 271 is formed in a semicircular cross-sectional shape, and a concave groove 276 is extended in the vertical direction at the front portion of the inner peripheral surface 270A. The feed passage 210 is formed to extend to the bottom. In other words, the concave groove 276 constitutes a feed passage forming region that forms the feed passage 210. Further, as shown in FIG. 20A, the concave groove 276 is transverse to the straight line Z that faces the front-rear direction passing through the rotational axis of the lifting screw body 206 in the transverse sectional view of the lifting case body 208. The pumping passage 210 communicates with a pumping ball outlet 209 (see FIG. 13) formed in the upper part of the concave groove 276.

  Further, presser portions 277A and 277B for pressing the lifting screw body 206 are formed in the center portion in the vertical direction on the inner peripheral surface 271A. The front surfaces 277E of the presser portions 277A and 277B are formed in an arc shape, and particularly protrude inward from the inner peripheral surface 271A. In addition, the holding portions 277A and 277B are formed to be divided into left and right by a concave groove 276, and extend in the vertical direction so as to correspond to the holding portions 275A to 275D of the second case 270, respectively. That is, it extends in the vertical direction from the upper presser portion 275A to a position corresponding to the lower presser portion 275D. In addition, a cylindrical bearing portion 280 for supporting the upper portion of the lifting screw body 206 is formed on the upper portion of the first case 271.

  The lifting case body 208 configured as described above rotates the upper case 270H and the lower case 270L of the second case 270 with respect to the first case 271, and a plurality of engagement cases are formed in the upper case 270H and the lower case 270L, respectively. The joint portion 278 is elastically engaged with the engaged portion 279 formed in the first case 271 and combined with each other, thereby forming a cylindrical accommodation space capable of accommodating the lifting screw body 206 therein. In addition, a lifting passage 210 for lifting the game ball P is formed in communication with the accommodation space by the concave groove 276 of the first case 271.

  In the state where the lifting case body 208 is attached to the back surface of the pachinko gaming machine 2, for example, a problem such as a ball clogging occurs in the lifting passage 210 or a game ball remaining in the lifting passage 210 is extracted. If necessary, the lower case 270L or the lower case 270L and the upper case 270H can be easily dealt with without removing the lifting case 208.

  Further, by combining the second case 270 and the first case 271, the inner peripheral surface 270A of the second case 270, the inner peripheral surface 271A of the first case 271 and the front surface 274E of the rib 274 are formed into the concave groove 276. A substantially circular inner peripheral surface (first presser portion) in a cross-sectional view with a corresponding part cut out is formed (see FIG. 20B), and the front surface 275E of the presser portions 275A to 275D of the second case 270. And the front surface 277E of the pressing portions 277A and 277B of the first case 271 form a substantially circular inner peripheral surface (second pressing portion) in a cross-sectional view with a portion corresponding to the concave groove 276 cut away (see FIG. 20 (A)).

  The inner peripheral surface (second presser portion) formed by the front surface 275E of the presser portions 275A to 275D of the second case 270 and the presser portions 277A and 277B of the first case 271 is formed on the second case 270. Provided closer to the outer periphery of a spiral protrusion 403 (described later) of the lifting screw body 206 than the inner peripheral surface (first pressing portion) formed by the inner peripheral surface 270A and the inner peripheral surface 271A of the first case 271. It is done. Specifically, as shown in FIG. 20A, the outer periphery of a spiral protrusion 403, which will be described later, of the lifting screw body 206, the front surface 275E of the holding portions 275A to 275D, and the holding portions 277A and 277B of the first case 271. The gap dimension L3 between the front surface 277E of the second case 270E is shorter than the gap dimension L4 between the outer periphery of the spiral protrusion 403 and the inner peripheral surface 270A of the second case 270 and the inner peripheral surface 271A of the first case 271. (L3 <L4).

  As described above, the inner peripheral surface (first pressing portion) formed by the inner peripheral surface 270A of the second case 270 and the inner peripheral surface 271A of the first case 271 and the second case around the lifting screw body 206. The inner peripheral surface (second presser portion) formed by the front surface 275E of the presser portions 275A to 275D of the 270 and the front surface 277E of the presser portions 277A and 277B of the first case 271 is disposed close to the Even if the screw body 206 sways in the horizontal direction due to rotation, the slidable contact with these inner peripheral surfaces restricts the shake, so that the horizontal movement of the lifting screw body 206 affects the lifting of the game ball P. Is prevented from reaching.

  In particular, since the central portion that is not supported like the upper and lower portions of the lifting screw body 206 is more likely to be shaken in the horizontal direction compared to the upper and lower portions that are pivotally supported, the presser portions 275A to 275D By disposing the inner peripheral surface (second presser portion) made up of the presser portions 277A and 277B close to each other, the horizontal movement of the lifting screw body 206 in the horizontal direction is more preferable than the central portion while suppressing the shake of the feed screw body 206 in the horizontal direction. At the upper and lower portions of the lifting screw body 206 that are less likely to sway, the inner peripheral surface (first presser portion) composed of the inner peripheral surface 270A of the second case 270 and the inner peripheral surface 271A of the first case 271 is formed inside. By disposing it away from the peripheral surface (second presser part), it is possible to reduce the frictional resistance due to sliding contact with the lifting screw body 206 as much as possible and to favor the horizontal movement of the lifting screw body 206. It can be suppressed.

  Further, as shown in FIG. 13, a plurality of presser portions 275 </ b> A to 275 </ b> D are provided in the vertical direction with a space therebetween, so that frictional resistance due to sliding contact compared to the case where one presser portion having a long vertical dimension is provided. It is possible to suitably suppress blurring in the horizontal direction while reducing as much as possible. Further, since the holding portions 277A and 277B are partially provided in a part in the circumferential direction, the frictional resistance due to the sliding contact with the lifting screw body 206 can be reduced as compared with the case where the holding portion is provided in the circumferential direction. While reducing as much as possible, the horizontal movement of the lifting screw body 206 can be suitably suppressed.

  Further, in this embodiment, the presser portion corresponds to a plurality of presser portions 275A to 275D extending in the circumferential direction on the inner periphery of the second case 270 and the presser portions 275A to 275D on the inner periphery of the first case 271. A plurality of presser portions 277A and 277B which are arranged at positions and extend in the vertical direction, so that the frictional resistance due to sliding contact with the lifting screw body 206 is reduced as much as possible, and the lifting screw body 206 In addition, it is possible not only to suitably suppress the horizontal movement of the lifting case body 208, but also half of the inner peripheral surface of the lifting case body 208 is in sliding contact with the lifting screw body 206 in the circumferential direction, and the remaining half is the lifting screw. Since the body 206 is in sliding contact with the body 206 in the vertical direction, the lifting screw body 206 can be supported more stably.

  As shown in FIG. 7, the lifting screw body 206 includes a screw shaft 400 made of a metal pipe extending in the vertical direction, and screw members 401 </ b> A, 401 </ b> B, 401 </ b> C installed around the screw shaft 400.

On the lower surface of the enlarged diameter portion 410, a cylindrical fitting portion 411A formed at the center position, a linear fitting portion 411B formed on the left and right sides of the fitting portion 411A, and an arcuate hollow portion 412 are formed. The enlarged diameter portion 410 has an outer diameter that is longer than the outer diameter of the cylindrical portion 402 and is formed to have substantially the same diameter as the rotating plate 222 of the ball delivery mechanism portion 201, and is placed on the upper surface of the rotating plate 222. As a result, the protrusion 241A is fitted into the fitting part 411A, and the protrusion 241B is fitted into the fitting part 411B, whereby relative rotation about the drive shaft 93A is performed with respect to the rotating disk 222. Linked impossible. That is, the screw member 401A is coupled to the rotating disk 222 so as to rotate together with the rotating disk 222 about the drive shaft 93A.

  At the upper end portion of the cylindrical portion 402, a notched portion 420A formed by notching a semicircular portion is formed. A convex portion 421A that protrudes upward is formed on the upper end surface of the cylindrical portion 402, and a concave portion 422A that opens upward is formed on the lower end surface of the notch portion 420A.

  As shown in FIG. 14F, the upper surface 403F of the spiral protrusion 403 is inclined downward in a direction away from the rotation axis, and is orthogonal to the rotation axis of the lifting screw body 206.

That is, the inclination angle θ2 of the lower surface 403B with respect to the orthogonal line C is larger than the inclination angle θ1 of the upper surface 403F. In addition, the protruding length L10 from the outer peripheral surface of the cylindrical portion 402 to the outer peripheral end surface of the spiral protrusion 403 is about 4.1 mm.

  As shown in FIG. 15, the screw member 401 </ b> B has a notch 420 </ b> A formed by notching a semicircular part at the upper end of the cylindrical part 402 and a notch 420 </ b> B at the lower end. The notch 420A is formed on one side, and the notch 420B is formed on the other side. A convex portion 421A that protrudes upward is formed on the upper end surface of the cylindrical portion 402, and a concave portion 422A is formed on the lower end surface of the notch portion 420A. A convex portion 421B that protrudes downward is formed on the lower end surface of the cylindrical portion 402, and a concave portion 422B is formed on the upper end surface of the notch portion 420B.

  Further, as shown in FIG. 15G, the upper surface 403F of the spiral protrusion 403 is inclined downward in the direction away from the rotation axis and is orthogonal to the rotation axis of the lifting screw body 206. The inclination angle θ3 with respect to the orthogonal line C is about 5.5 degrees (θ3 = about 5.5 degrees). Further, the lower surface 403B of the spiral protrusion 403 is inclined upward in a direction away from the rotation axis, and the inclination angle θ2 with respect to the orthogonal line C perpendicular to the rotation axis of the lifting screw body 206 is about It is set to 21.5 degrees (θ4 = about 21.5 degrees). That is, the inclination angle θ4 of the lower surface 403B with respect to the orthogonal line C is larger than the inclination angle θ1 of the upper surface 403F. Further, the protruding length L11 from the outer peripheral surface of the cylindrical portion 402 to the outer peripheral end surface of the spiral protrusion 403 is about 6 mm.

  As shown in FIG. 16, the screw member 401 </ b> A has a notch 420 </ b> B formed by notching a semicircular portion at the lower end of the cylindrical portion 402. Further, a convex portion 421B that protrudes upward is formed on the upper end surface of the cylindrical portion 402, and a concave portion 422B that opens upward is formed on the lower end surface of the notch portion 420B. Note that a cutout 420C formed by cutting out a semicircular portion is formed at the upper end of the cylindrical portion 402, and a recess 422C opening upward is formed on the opposite side of the cutout 420C.

  Further, as shown in FIG. 16G, the upper surface 403F of the spiral protrusion 403 is inclined downward toward the direction away from the rotation axis, and is orthogonal to the rotation axis of the lifting screw body 206. The inclination angle θ1 with respect to the orthogonal line C is about 5.5 degrees (θ1 = about 5.5 degrees). Further, the lower surface 403B of the spiral protrusion 403 is inclined upward in a direction away from the rotation axis, and the inclination angle θ2 with respect to the orthogonal line C perpendicular to the rotation axis of the lifting screw body 206 is about It is set to 21.5 degrees (θ2 = about 21.5 degrees).

Further, the protruding length L12 from the outer peripheral surface of the cylindrical portion 402 to the outer peripheral end surface of the spiral protrusion 403 is about 6 mm. A horizontal portion 423 is formed at the upper end of the spiral protrusion 403 so as to expand in a substantially semicircular shape at a position slightly below the upper end of the cylindrical portion 402.

  The screw members 401 </ b> A, 401 </ b> B, and 401 </ b> C configured as described above insert the cylindrical portion 402 from the upper end or the lower end of the screw shaft 400. At this time, one screw member 401A is disposed below the screw shaft 400, one screw member 401C is disposed above the screw shaft 400, and five screw members 401B are disposed between the screw members 401A and 401C on the screw shaft 400. (Refer to FIG. 7). In addition, what is necessary is just to change the number of arrangement | positioning of the screw member 401B according to length, when changing the length of the conveyance path 210. FIG.

  As shown in FIG. 17, when connecting the screw members 401A, 401B, 401C to each other, for example, the upper end of the lower screw member 401B is fitted to the notch 420B at the lower end of the upper screw member 401B. Let Thereby, as shown in the enlarged view in FIG. 17B in particular, the convex portion 421B of the upper screw member 401B is fitted into the concave portion 422A of the lower screw member 401B. Thereby, the upper and lower ends of the spiral ridges 403 of the upper and lower screw members 401B connected to each other are connected to form a continuous spiral ridge 403, and the upper and lower screw members 401B connected to each other are formed. Of these, relative rotation around the other screw shaft 400 is restricted.

  As shown in the enlarged view of FIG. 17B, the protrusion dimension L1 from the end surface of the cylindrical portion 402 in the convex portion 421B (the convex portion 421A) is from the end surface of the cylindrical portion 402 in the concave portion 422B (the concave portion 422A). It is shorter than the depth dimension L2. Therefore, the upper and lower screws connected to each other are suppressed by preventing a gap from being generated between the connecting end surfaces of the upper and lower screw members 401B due to molding errors of the convex portions 421B (the convex portions 421A) and the concave portions 422B (the concave portions 422A). It is suppressed that the connection end surfaces of the spiral protrusion 403 of the member 401B are separated from each other and a gap or a step is formed.

  As shown in FIG. 18, the lifting screw body 206 composed of the screw shaft 400 and the screw members 401 </ b> A, 401 </ b> B, 401 </ b> C is accommodated in the lifting case body 208 as shown in FIG. It is arranged along. Specifically, the lower screw member 401A of the lifting screw body 206 is placed on the upper surface of the rotating disk 222, and the upper end 400A of the screw shaft 400 protrudes upward from the upper end of the screw member 401C, and the lifting case body. 208 is rotatably supported in a bearing hole 281A formed in a bearing member 281 provided in a bearing portion 280 in 208. Therefore, when the rotary plate 222 is rotated by the lifting motor 93, the lifting screw body 206 rotates about the drive shaft 93A of the lifting motor 93 and the screw shaft 400 concentric with the driving shaft 93A.

  As shown in FIG. 18, in the state where the lifting screw body 206 is disposed inside the lifting case body 208, the holding portions 275A to 275D are connected to the screw members 401A, 401B, 401C (for example, The convex portion 421B and the concave portion 422A, and the fitting portion between the convex portion 421A and the concave portion 422B) are arranged at positions shifted in the axial direction (vertical direction). Thereby, when the lifting screw body 206 is in contact with the presser portions 275A to 275D, it is possible to reduce the load on the connection portion between the screw members 401A, 401B, 401C, and to improve durability.

  As shown in FIG. 19, at the portion of the screw shaft 400 that protrudes from the upper end of the screw member 401 </ b> C, the game ball P that has been lifted up to the horizontal portion 423 that is the uppermost portion of the spiral protrusion 403 is A discharge member 440 is provided for discharging from the storage. The discharge member 440 includes a cylindrical portion 442 having a through hole 441 through which the screw shaft 400 can pass, and an extrusion portion 443 extending in the horizontal direction from the cylindrical portion 442, and the through hole 441 is formed in the screw shaft 400. By inserting, the cylindrical portion 442 is disposed on the upper end of the screw member 401C, and the pushing portion 443 is disposed on the upper surface of the horizontal portion 423 of the spiral protrusion 403. In addition, when the discharge member 440 is disposed on the upper surface of the horizontal portion 423, the discharge shaft 440 is prevented from being lifted by attaching a C-shaped retaining ring 445 to the screw shaft 400.

  A curved surface 443A having an arc shape in plan view is formed on the side surface in the rotational direction of the lifting screw body 206 in the pushing portion 443. As shown in FIG. 19B, in the state where the lifting screw body 206 is accommodated in the lifting case body 208, the horizontal portion 423 of the spiral protrusion 403 is disposed at a position slightly below the lower side of the lifting ball outlet 209. Thus, the push-out portion 443 of the discharge member 440 is arranged at a lower position of the lifting ball outlet 209.

  Here, the game ball P sent out by the ball feed rotating body 205 in the ball delivery mechanism unit 201 is a spiral projection of the screw member 401A at the lifting position Y, which is the lower position of the lifting passage 210 formed by the wall 240B. It is scooped up by the lower part of the strip part 403, and it is pumped up by the pumping path 210 (refer to the area shown by halftone dots in FIG. 19) formed by the concave groove 276 of the first case 271.

  Specifically, as shown in FIGS. 19 and 20, about 2/3 of the game ball P that has entered the lower portion of the lifting passage 210 formed by the concave groove 276 is accommodated in the concave groove 276 in plan view. At the same time, the remaining approximately one third is disposed in contact with the upper surface 403F of the spiral ridge 403 so as to overlap a part of the spiral ridge 403 (FIGS. 21A and 22B). reference). Therefore, as the lifting screw body 206 rotates, the game ball P is pushed upward and in the rotation direction by the upper surface 403F of the spiral protrusion 403, but about 2/3 of the game ball P is recessed 276. By being housed inside and being restricted from moving in the rotational direction, it is guided upward along the lifting passage 210.

  As shown in FIG. 21A, the lead angle θ10 of the spiral protrusion 403 of this embodiment is about 15.6 degrees (θ10 = 15.6 degrees), as shown in FIG. In addition, the lead angle θ11 of the conventional spiral protrusion 403 is about 46.78 degrees (θ11 = 46.78 degrees), and the direction of pressing against the wall portion of the lifting case body 208 with respect to the traveling direction (Y component) The vector ratio of (X component) is as shown in FIG. That is, in the present embodiment, the ratio of the X component is suppressed to about 1/4 with respect to the conventional one, so that even when the friction is increased, the influence is reduced to about 1/4.

  Further, as shown in FIG. 22A, the inclination angles θ1, θ3, θ5 with respect to the orthogonal line C on the upper surface 403F of the spiral protrusion 403 of this embodiment are about 5.5 degrees (θ1, θ3, θ5 = As shown in FIG. 22B, the inclination angle θ20 with respect to the orthogonal line C on the upper surface 403F of the conventional spiral protrusion 403 is about 21.5 degrees (θ20 = 21.5 degrees). FIG. 22 shows the vector ratio of the direction (X component) pressed against the wall of the lifting case 208 with respect to the traveling direction (Y component). That is, in the present embodiment, the ratio of the X component is suppressed to about 1/4 with respect to the conventional one, so that even when the friction is increased, the influence is reduced to about 1/4.

  As described above, the lead angle θ10 and the inclination angles θ1, θ3, θ5 in the spiral ridge portion 403 of the present embodiment are as described above, and therefore the pump is fed as compared with the conventional spiral ridge portion. When the game ball P is pressed against the wall portion of the lifting case body 208, that is, the inner peripheral surface of the concave groove 276, the frictional resistance generated between the wall portion and the game ball P is reduced. Therefore, the game ball P can be smoothly lifted without applying a load to the lift motor 93.

  Further, the protruding length L10 of the spiral protrusion 403 of the screw member 401A is shorter than the protruding lengths L11 and L12 of the spiral protrusion 403 of the screw members 401B and 401C (L10 <L11, L12). ). Thus, in the lower part of the lifting passage 210, that is, on the upstream side of the lifting, the protruding length of the spiral protrusion 403 is shortened so that the game ball P can be easily picked up, and the protruding length is increased in the middle. Lifting of the game ball P can be stabilized.

  In this embodiment, only the protrusion length L10 of the spiral protrusion 403 of the screw member 401A is shorter than the protrusion lengths L11 and L12 of the spiral protrusion 403 of the screw members 401B and 401C. The invention is not limited to this, and the protruding lengths of all the spiral protrusions 403 may be the same.

  In the present embodiment, the screw members 401A, 401B, and 401C have the same pitch (vertical interval) between the spiral protrusions 403, but the present invention is not limited to this. While reducing the pitch of the spiral ridges 403 of the screw members 401A and 401C and placing importance on the stability at the start of lifting and discharging, the pitch of the helical ridges 403 of the screw member 401B is increased. You may make it vary at least a pitch so that emphasis may be placed on increasing the feeding speed.

The game board 26 is further provided with a display control board (effect control board) for controlling a variable display device (not shown) and the like.

  The payout control board 17 is provided in the gaming machine frame 4. The payout control board 17 is equipped with a payout control microcomputer which is a payout control unit 171.

  The payout control microcomputer includes a CPU (Central Processing Unit) as a control center, a ROM (Read Only Memory) storing a program and control data for operating the CPU, and a RAM (Random) functioning as a work area of the CPU. Access Memory), and an input / output interface for maintaining signal consistency with peripheral devices.

  In addition, the payout control board 17 is provided with a ball removal operation button 19 (automatic operation means). The ball removal operation button 19 is subjected to mechanical restraint from the polishing device 23 or the like when, for example, the game ball is discharged from the ball removal hole 76 (the ball removal hole cover 77) and the surplus ball retaining portion 69 described above. Therefore, a driving source (specifically, a polishing motor 71) for discharging game balls that cannot be discharged by automatic flow down from the ball hole 76 simply by opening the ball hole cover 77 (in the pachinko gaming machine 2). Buttons for automatically operating the lifting motor 93, the ball feeding solenoid 47, and the firing solenoid 41).

  Further, with respect to the payout control board 17, the firing ball detection sensor 99, the polishing entrance ball detection switch 701, the foul ball detection switch 33, the lifting motor 93, the polishing motor 71, the ball feeding solenoid 47, the first fullness detection sensor 75, the first 2 The fullness detection sensor 40, the counting button 28, and the radio wave sensor 173 are provided in an electrically connected state. The radio wave sensor 173 is for detecting an illegal act of illegally transmitting radio waves.

  A detection signal of the radio wave sensor 173 is input to the payout control unit 171 via an input port (not shown) of the payout control board 17.

  However, if an illegal radio wave is generated, the number of game balls is not subtracted no matter how many balls are fired. Such radio fraud is detected by the radio wave sensor 173. Here, there is a possibility that the launch ball detection sensor 99 may be a target of fraud by radio waves. That is, when a ball that has been actually fired is collected and detected by the fired ball detection sensor 99, the number of the fired ball and the collected ball (out ball) is wrinkled. The fraud detection information “OUT inconsistent number of balls” is transmitted from the pachinko gaming machine 2 to the card unit 3. However, fraud detection information of the “number of inconsistent spheres / launch / OUT” is transmitted from the pachinko gaming machine 2 to the card unit 3 by transmitting an illegal radio wave to the firing ball detection sensor 99 to make it undetectable. Inconvenience disappears. In this embodiment, since the radio wave sensor 173 also detects the illegal radio wave transmitted to such a launch ball detection sensor 99, the above-described inconvenience can be prevented.

  Further, a launch ball detection sensor 99 is provided on the slightly moving side of the ball feed solenoid 47, and the detection state of the game ball by the launch ball detection sensor 99 is changed from the detection state to the non-detection state as described above. Each time, the payout control unit 171 subtracts “1” from the number of game balls. Specifically, the subtraction ball number counter is updated by adding “1”, and the game ball number is updated by subtracting “1”.

  As another modified example of subtracting and updating the number of game balls by “1”, there is a method using a foul ball detection switch 33. Originally, when the foul ball is filled in the second ball passage 45, the foul ball detection switch 33 detects the full foul ball as described later. In this case, the foul ball detection switch 33 outputs a continuous detection signal instead of an instantaneous pulse signal, and the payout control unit 171 that has received the continuous detection signal causes the second ball passage 45 to foul. Judge that the ball is full. On the other hand, when the ball feed solenoid 47 is energized once and one game ball flows down the second ball passage 45 and the passing ball is detected by the foul ball detection switch 33, an instantaneous pulse signal is generated. Output from the sphere detection switch 33. The payout control unit 171 that has received the instantaneous pulse signal may perform control so that the subtraction ball number counter is updated by adding “1” and the number of game balls is updated by adding “1”.

  Thus, the foul ball detection switch 33 is configured to detect a game ball passing through the second ball passage 45 and to detect a foul ball filling the second ball passage 45 in order to subtract the number of game balls. It may be configured as a dual-purpose switch that detects both.

  Further, as described above, the payout control unit 171 changes to the oversupply state due to the small spheres mixed in the first ball passage 44, so that the second fullness detection sensor 40 enters the ball detection state, and When the launch ball detection sensor 99 is in a non-ball detection state, an error notification process is executed. In the present embodiment, the payout control unit 171 outputs an error signal indicating that the first ball passage 44 is oversupplied to the CU control unit 323 as an error notification process, and the first ball passage 44 is oversupplied. A process of displaying error information (not shown) indicating that the state has been reached on the display 54 is executed. Since the error information is displayed on the display device 54 in this manner, it becomes easier for a store clerk or the like in the game hall to know that an error has occurred in the first ball passage 44, and thus it is possible to suppress fraud.

  In the present embodiment, the payout control unit 171 sends the second control sensor 171 to the CU control unit 323 based on the fact that the second fullness detection sensor 40 is in a ball detection state and the firing ball detection sensor 99 is in a non-ball detection state. The error information (not shown) is displayed on the display 54 via the CU control unit 323 by outputting an error signal indicating that the one-ball passage 44 is in an oversupply state. However, the first ball passage 44 is over-supplied to the effect control unit provided on the effect control board (not shown) connected to the main control board 16. By outputting an error signal indicating this, the effect control unit may display the error information via a predetermined display (for example, an effect display device or the like).

  In the present embodiment, the predetermined error information is displayed on the display 54 as an error notification indicating that the first ball passage 44 is in an oversupply state, but the present invention is limited to this. For example, a light emitting means (not shown) such as an LED provided in the pachinko gaming machine 2 emits light, or a process of outputting a predetermined sound from a speaker (not shown) or the like is performed. Good.

  Further, the payout control unit 171 causes the first ball passage 44 to be oversupplied to an external device such as a hall management computer or a hall server (not shown) that performs security management without passing through the card unit 3. An error signal indicating that the error has occurred may be directly output from the pachinko gaming machine 2 to the outside. In other words, it is not limited to the process of displaying error information on the display unit, causing the light emitting means to emit light, outputting sound, etc., but only performing the process of outputting an output signal to an external device. But you can. By doing in this way, since it is possible to monitor a fraudulent act on the game hall side so that an unauthorized person is not noticed, it is possible to prevent the unauthorized person from escaping due to error notification.

  Furthermore, not only a process for outputting an error signal indicating that an oversupply state has occurred, but also a process for stopping the progress of the game, for example, stopping the driving of the launching device 14 (ball feed solenoid 47). You may make it perform.
