  As described above, conventionally, various control devices for performing control related to games and payout mechanisms for paying out game balls are provided on the back side of gaming machines such as pachinko machines. The payout mechanism includes a storage tank that temporarily stores a large amount of game balls supplied from the ball supply means provided in the island facility of the game hall, and aligns the game balls derived from the storage tank. The game balls are sequentially guided to the payout device via guide rails (tank rails and case rails) that flow down. Then, the game balls paid out from the payout device are led out to a ball tray on the front side of the gaming machine through a predetermined ball passage.

  When supplying from the ball supply means or when the game balls sequentially move through the payout mechanism, static electricity may be generated due to contact between game balls, contact with components of the payout mechanism, or the like.

  When a game ball is charged and a discharge phenomenon occurs, the electronic device or electronic device is damaged by the discharge current (direct ESD), or malfunction of the electronic device is induced by electromagnetic noise generated by the discharge. Various inconveniences such as indirect ESD may occur. For example, there is a concern about malfunction of the payout device or various control devices, erroneous detection of the ball detection sensor, mixing of noise into the control signal, or the like.

  Therefore, in order to prevent such a situation, conventionally, various measures have been taken to release the static electricity charged in the game ball or the like to the outside of the machine. For example, there is a configuration in which the constituent members of the payout mechanism are formed of a conductive resin material or the like, and these are connected to the external ground of the island facility via a predetermined electrical connection means to remove charged static electricity.

  In particular, there is a high frequency of game balls colliding with each other, such as a storage tank to which game balls are supplied from the ball supply means, and a tank rail that receives and aligns game balls falling from the storage tank. In order to cope with locations that are easy to handle, the resistivity of conductive materials used for storage tanks, tank rails, etc. should be lower than the low efficiency of conductive materials used for dispensing devices, etc. A technique that can be removed has already been disclosed by the present applicant (see, for example, Patent Document 1).

  However, in the invention described in Japanese Patent No. 4259415, all of the storage tank, the tank rail, the case rail, and the dispensing device are electrically connected to the metal plate and thus the hinge, It is configured to be removed out of the machine via a hinge.

  For this reason, for example, static electricity charged on the game ball in the storage tank flows from the storage tank to the metal plate via the tank rail, and further flows to the dispensing device via the metal plate, causing malfunctions of the dispensing device, etc. May occur.

  The present invention has been made to solve the above-described problems and the like, and an object of the present invention is to provide a gaming machine that can suppress the occurrence of problems caused by electrostatic charging or the like.

  Hereinafter, an embodiment of a pachinko gaming machine (hereinafter simply referred to as “pachinko machine”) will be described in detail with reference to the drawings. FIG. 1 is a front view of the pachinko machine 10, and FIG. 2 is a perspective view showing a state in which a front frame set 14 and a lower tray unit 13 as front doors are opened with respect to an outer frame 11 and an inner frame 12 which will be described later. FIG. However, in FIG. 2, for convenience, a game board 42 and a glass unit 150 described later are omitted.

  As shown in FIGS. 1 and 2, the pachinko machine 10 includes an outer frame 11 that constitutes an outer shell of the pachinko machine 10, and an inner frame 12 is supported on the left side of the outer frame 11 so as to be openable and closable. Yes.

  Here, the outer frame 11 will be described with reference to FIG. FIG. 3 is a perspective view showing the entire outer frame 11. In the outer frame 11 in the present embodiment, the upper side frame constituting part 11a and the lower side frame constituting part 11b are constituted by a wooden plate material, and the left side frame constituting part 11c and the right side frame constituting part 11d are constituted by an aluminum alloy extrusion molding material. These frame constituent portions 11a to 11d are assembled in a rectangular frame shape as a whole by a detachable fastener such as a screw.

  The left side frame constituting part 11c and the right side frame constituting part 11d are formed by extruding an aluminum alloy as a raw material in a predetermined cross-sectional shape under high temperature and high pressure, cutting the extruded molded material into a predetermined dimension, and screwing it by cutting or the like. It can be obtained by machining small parts such as screw holes for fastening.

  An upper hinge fitting 15 and a lower hinge fitting 16 are attached to upper and lower ends of the left side frame constituting portion 11c, respectively. On the other hand, as shown in FIGS. 19 and 20, support metal fittings 65 and 66 are attached to upper and lower ends of the left side of the inner frame 12 (right side in FIGS. 19 and 20). Then, by attaching the support brackets 65 and 66 of the inner frame 12 to the hinge brackets 15 and 16 of the left side frame constituting portion 11c, the inner frame 12 is attached to the outer frame 11 so as to be opened and closed. More specifically, the upper hinge fitting 15 has an insertion hole 15a, and the lower hinge fitting 16 has a protruding portion 16a protruding upward. On the other hand, the support metal fittings 65 and 66 are provided with projections inserted into the insertion holes 15a and insertion holes into which the projections 16a are inserted, although illustration is omitted. By assembling each of these, the upper and lower portions of the inner frame 12 are rotatably supported, and the inner frame 12 can be opened and closed. That is, the opening / closing axis of the inner frame 12 is set so as to extend vertically to the left as viewed from the front of the pachinko machine 10, and the inner frame 12 can be opened forward with the opening / closing axis serving as an axis. . The main body of the gaming machine such as the inner frame 12 or the back pack unit 203 is housed in a space formed inside the outer frame 11.

  On the other hand, a pair of upper and lower pawl horses 17 and 18 are attached to the inner side of the right side frame constituting portion 11d corresponding to rod members 192 and 193 (see FIG. 13 and the like) of the locking device G1 described later. When the inner frame 12 is closed, the hook members 192 and 193 are engaged with the claw horses 17 and 18 to thereby restrict the opening of the inner frame 12.

  The claw horses 17 and 18 in the present embodiment are provided with so-called folded portions 17a and 18a by bending the tip portions thereof at substantially right angles. When the inner frame 12 is in the closed state due to the presence of the folded portions 17a and 18a, the engagement state of the barbs 192 and 193 can be stabilized without increasing the length of the pawls 17 and 18 themselves. As a result, the electrical conduction state between the claw horses 17 and 18 and the flange members 192 and 193 can be more reliably stabilized.

  In addition, the hinge metal fittings 15 and 16 in this embodiment, the support metal fittings 65 and 66, and the claw horses 17 and 18 are more rigid than the outer frame 11 main body (the left side frame structure part 11c and the right side frame structure part 11d) made from aluminum alloy. It is formed of a high cold rolled steel sheet (SPCC or the like), an electrogalvanized steel sheet (SECC or the like), or the like.

  Further, as shown in FIG. 3, since the bases of the claw horses 17 and 18 are directly screwed to the inner surface of the right side frame constituting part 11d, the claw horses 17 and 18 and the right side frame constituting part 11d are electrically connected. Is in an electrically conductive state.

  A resin frame decoration 19 is attached to the lower frame constituting portion 11b of the outer frame 11. In addition, metal sliding members 21 and 22 are provided on the upper surface of the curtain decoration 19, thereby ensuring smooth sliding when the inner frame 12 is opened and closed. In addition, a rib 23 protruding upward is integrally formed at the back of the upper surface of the curtain decoration 19. This makes it difficult to form a gap between the inner frame 12 and in this sense, fraud is prevented.

  Returning to the description of FIGS. 1 and 2, the main body of the inner frame 12, the lower dish unit 13, and the front frame set 14 is made of an insulating synthetic resin, specifically, ABS (acrylonitrile-butadiene-styrene) resin. Yes. By using a synthetic resin for molding the main body portion of each member, it is possible to cope with a more complicated shape as compared with the case where a metal material is used, and to suppress an increase in production cost. Advantages of using ABS include a low production cost, strong viscosity, and high impact resistance compared to resin materials such as polycarbonate. In addition, for example, when a coating process such as plating is performed on a design surface such as the front side of the front frame set 14, the process is relatively easy to perform, and there is an advantage that a product with higher appearance quality can be manufactured.

  The front frame set 14 and the lower tray unit 13 are attached to the inner frame 12 so as to be openable and closable. Both the lower pan unit 13 and the front frame set 14 can be opened to the front side with an open / close axis extending vertically to the left when viewed from the front of the pachinko machine 10, as in the case of the inner frame 12.

  FIG. 4 is a front view showing a state in which the front frame set 14 is removed from the pachinko machine 10 (however, in FIG. 4, the configuration in the game area on the surface of the game board 42 is shown as blank for convenience). Note that a rib R1 projects from the front side of the inner frame 12 at a periphery thereof (a portion corresponding to the front frame set 14). When the front frame set 14 is closed, the front frame set 14 is fitted into the rib R1. With this configuration, it becomes difficult to allow a wire or the like to enter from the gap between the front frame set 14 and the inner frame 12 and plays a role in preventing fraud.

  As shown in FIG. 2, a part of a game ball launching unit 70, which will be described later, a relay board DK, and the like are housed in the housing recess 24 provided at a position corresponding to the lower dish unit 13 below the inner frame 12. .

The game board 42 is provided with a general winning port 43, a variable winning device 44, a first opportunity corresponding port (starting port) 45, a second opportunity corresponding port (through gate) 46, and the like as a ball entry means. A variable display unit 47 is provided. These are disposed in through holes formed by router processing, and are attached from the front side of the game board 42 with wood screws or the like. As is well known, a game ball enters the general winning port 43, the variable winning device 44, and the first opportunity corresponding port 45, and a predetermined number of prizes are given to the upper plate 37 (or the lower plate 31) by the output of a detection switch described later. The ball is paid out. In addition, the game board 42 is provided with an out port 48, and game balls that have not entered the various winning units (winning device, winning port, first opportunity corresponding port 45, etc.) pass through the out port 48. It is now guided to the ball discharge path. A number of nails are planted on the game board 42 in order to disperse and adjust the falling direction of the game balls as appropriate, and various members (functions) such as a windmill 49 are arranged.

  The variable display device unit 47 includes a second symbol display device 51 that variably displays the second symbol triggered by the passage of the second trigger corresponding port 46, and a first symbol ( There is provided a first symbol display device 52 (special symbol display device) for variably displaying special symbols. The second symbol display device 51 (ordinary symbol display device) includes a display portion 53 for a second symbol (ordinary symbol) and a holding lamp 54, and each time a game ball passes through the second opportunity corresponding port 46, for example, When the display symbol (second symbol) by the display unit 53 fluctuates and the variation display stops at a predetermined symbol, the first opportunity corresponding port 45 is configured to be in an activated state (opened) for a predetermined time. .

  When a game ball newly passes through the second opportunity corresponding port 46 during the second symbol variation display on the display unit 53 of the second symbol display device 51, the corresponding second symbol variation display is It is configured to be performed after the end of the variable display performed at the time. That is, the variable display is on standby (held). The maximum number of the variable display to be held is determined for each model of the pachinko machine, but in this embodiment, it is held up to 4 times, and the hold number is lit and displayed by the hold lamp 44. Yes. However, the maximum number of holding times is not limited to this. For example, the maximum hold count may be set to 8 in order to wait for the second symbol variation display for 8 times. Note that the display unit 53 may be configured to be variably displayed on a part of the first symbol display device 52 (liquid crystal display device) in addition to the configuration to be variably displayed by switching the lighting of a plurality of lamps. . Similarly, the hold lamp 54 may be configured to be variably displayed on a part of the first symbol display device 52.

  The first symbol display device 52 is configured as a liquid crystal display device, and the display content is controlled by a display control device 55 described later. In the present embodiment, the first symbol display device 52 (liquid crystal display device) includes an 8 inch large liquid crystal display. A center frame 57 is disposed in the variable display device unit 47 so as to surround the first symbol display device 52.

  Although not shown in the figure, the first symbol display device 52 has three symbol rows, left, middle, and right, and the symbols (first symbols) are variably displayed for each symbol row. In the present embodiment, for example, the first symbol is configured so as to be given numbers “0” to “9”, respectively, and the first symbol is displayed in ascending or descending order of numbers to form a series of symbol strings. Yes. And the 1st symbol is variably displayed from top to bottom with periodicity.

  In this case, in the left symbol row, the first symbol is displayed in descending order (in the order in which the attached numbers decrease), and in the middle symbol row and the right symbol row, the first symbol is also in ascending order (the appended numbers are the same). (In increasing order). Then, the variable display stops in the order of left symbol sequence → right symbol sequence → middle symbol sequence, and at the time of the stop, the first symbol is a combination of jackpot symbols on the first symbol display device 52 (in this embodiment, the same first symbol sequence). A special game video is displayed as a jackpot if the symbols are combined (a combination of symbols) (a jackpot state is started).

  The variable winning device 44 is normally in a closed state in which a game ball cannot be won or difficult to win, and in an open state in which a game ball is likely to win in the case of a big win (occurrence of a special game state) and a normal closed state It is designed to be operated repeatedly. As described above, the game ball wins the first opportunity corresponding port 45, the symbols are displayed in a variable manner on the first symbol display device 52, and the confirmed symbol after the stop is a combination of specific symbols set in advance. When a special gaming state occurs with the above requirements, the large winning opening of the variable winning device 44 is in a predetermined open state, and the game ball is configured to be in a state where it is easy to win (a big hit state). Specifically, the passage of a predetermined time or a predetermined number of winnings is defined as one round, and the big winning opening of the variable winning device 44 is repeatedly opened a predetermined number of times.

  When a new game ball wins the first opportunity corresponding port 45 during the symbol variation display of the first symbol display device 52, the symbol variation display for that time is the end of the symbol variation display being performed at that time. The configuration is performed later. That is, the symbol variation display is waited (held, stored) (storage means). The maximum number of symbol variation display to be held is determined for each model of the pachinko machine, but in this embodiment, it is held up to 4 times, and the hold number is lit and displayed by the hold lamp 56. ing. However, the maximum number of holding times is not limited to this. For example, the maximum number of suspensions may be set to 8 in order to wait for 8 symbol fluctuation displays. Note that the hold lamp 56 may be configured to be variably displayed on a part of the first symbol display device 52.

  In addition, a guide rail for guiding the game ball launched from the game ball launch unit 70 to the upper part of the game board 42 is attached to the game board 42, and the game ball launched as the handle 35 is turned. Is guided to a predetermined game area through a guide rail.

Both rails 58 and 59 are made of a metal strip made of stainless steel. The inner rail 58 is formed in a substantially annular shape except for about 1/2 of the upper side and the right side. An outer rail 59 is provided so that a part (mainly the left side) faces the inner rail 58. In this case, a guide rail is mainly constituted by the inner rail 58 and the outer rail 59, and a ball guide passage is formed by a portion (the left portion facing) where the rails 58 and 59 are parallel to each other at a predetermined interval. Yes.

  A return ball preventing member 61 is attached to the tip of the inner rail 58 (the upper left portion in FIG. 7). This prevents a situation in which the game ball once guided from the ball guide path between the inner rail 58 and the outer rail 59 to the upper part of the game board 42 returns to the ball guide path again. Yes. Further, a resin arc member is provided between the end of the inner rail 58 opposite to the return ball preventing member 61 and the tip of the outer rail 59 (the right side). 62 is attached. A return rubber 63 is attached to the upper end portion (the portion on the outer rail 59 side) of the arc member 62, that is, the position corresponding to the maximum flying portion of the game ball (the upper right portion in FIG. 7). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 63 and is returned to, for example, the substantially central portion side of the game board 42. Note that the lower right corner and the lower left corner of the game board 42 are spaces for attaching a seal such as a certificate or a plate (for example, S1 in the lower right corner of FIG. 7).

  Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape by the inner periphery of the rail (inner and outer rails 58 and 59). In particular, in this embodiment, the game area partitioned on the board surface of the game board 42 is far more than conventional. It is greatly configured.

  In the present embodiment, the game area is an area of a guide rail that is a parallel part of the inner and outer rails 58 and 59 among the areas surrounded by the inner rail 58, the outer rail 59, and the arc member 62 when viewed from the front of the pachinko machine 10. The area is excluded. Accordingly, since the game area does not include the guide rail portion, the left limit position toward the game area is specified not by the outer rail 59 but by the inner rail 58. Similarly, the right limit position toward the game area is specified by the arc member 62. The lower limit position of the game area is specified by the lower end position of the game board 42. The upper limit position of the game area is specified by the outer rail 59.

A ball feeding unit 74 attached to the base plate 71 and a positioning member (not shown) attached to the base plate 71 to support and position the game ball placed on the base end portion of the firing rail 73. And.

  The launch rail 73 is for guiding the game ball immediately after being launched from the launch device 72, and extends linearly so as to have a predetermined launch angle (launch angle). Then, the game ball launched in accordance with the turning operation of the handle 35 is first launched obliquely upward along the launch rail 73 and then guided to a predetermined game area through the ball guide passages of the rails 58 and 59 as described above. It has become so.

  In the present embodiment, a linear solenoid is employed as the launching device 72 instead of a combination of a motor and launching rod that are generally employed conventionally. That is, the launching device 72 includes a plunger 76 extending in parallel with the firing rail 73, and a hitting portion 77 for hitting a game ball is attached to the tip of the plunger 76. Under such a configuration, the launch device 72 is repeatedly excited and de-energized every predetermined time, whereby the plunger 76 is repeatedly raised and retracted. Each time the plunger 76 protrudes, the game ball positioned at a predetermined position is launched from the launch rail 73. Note that the protruding speed of the plunger 76 is appropriately adjusted based on the operation amount of the handle 35 (the stroke amount is substantially constant), thereby adjusting the firing speed of the game ball and hence the flying amount. The firing device 72 is fixed with screws to four bosses erected on the base plate 71. In the present embodiment, the lower two bosses are fixed to the base plate 71. On the other hand, the upper two bosses can be adjusted in height (projection amount). Therefore, by appropriately adjusting the protrusion amount of the boss, the height (protrusion amount) to which the launching device 72 is attached, and consequently the tip position of the plunger 76, that is, the hitting point of the game ball can be adjusted. Yes.

  The ball feeding unit 74 is for guiding the game balls guided from the upper plate 37 side one by one to the base end portion (launching position) of the firing rail 73. It is attached to the base plate 71 through a resin pedestal 81 fixed to the base plate 71 so as to cover the surface.

  The ball feeding unit 74 includes a resin opening / closing portion 82 that is detachably attached to the front surface side of the pedestal portion 81, and has a configuration in which a predetermined ball feeding mechanism is accommodated in the opening / closing portion 82. . In the present embodiment, the pedestal portion 81 and the opening / closing portion 82 are transparent or translucent members, and are formed of a transparent or translucent synthetic resin. For this reason, the ball feeding mechanism accommodated inside can be visually recognized from the outside of the opening / closing part 82. For this reason, even when some trouble occurs in the ball feeding mechanism, the state can be recognized before the opening / closing part 82 is removed, as will be described later.

  More specifically, the opening / closing part 82 is provided with a pair of upper and lower shaft protrusions 82b on one side (right side in the figure), and the base part 81 has a pair of upper and lower bearing parts 81b into which the shaft protrusions 82b are inserted. Is provided. Thus, the opening / closing part 82 is pivotally supported on one side (right side in the drawing) of the pedestal part 81. That is, the opening / closing part 82 can be opened and closed at the base part 81. Further, the upper shaft convex portion 82b is formed with a locking convex portion 82c that protrudes outward from the main body portion of the shaft convex portion 82b along the left-right direction of the opening / closing portion 82 (the direction orthogonal to the rotation axis). A shaft locking member 81c capable of locking the locking projection 82c (shaft projection 82b) in the axial direction of the pedestal 81 is projected forward at a position substantially above the upper bearing portion 81b. It is installed. A part of the inner side (left side in the figure) of the pedestal portion 81 in the left-right direction is cut off in a tapered shape in the shaft locking member 81c. The taper shape (taper angle) in the present embodiment is inclined about 45 degrees to the right from the direction perpendicular to the pedestal portion 81 (the front-rear direction of the pachinko machine 10). Accordingly, the state in which the opening / closing part 82 is completely attached to the pedestal part 81, that is, the closed state (the state shown in FIG. 8), is inclined at an angle of about 45 degrees or more to the right with respect to the perpendicular direction of the pedestal part 81. The shaft convex portion 82b cannot be pulled out from the bearing portion 81b unless the shaft is rotated to the fully-opened state and substantially fully opened. That is, when the opening / closing part 82 is located in a specific rotation section from the closed state to the fully opened state as described above, the shaft convex part 82b cannot be removed from the bearing part 81b, and the opening / closing part 82 is placed on the base. The configuration is such that it cannot be removed from the portion 81. Of course, the shaft convex portion 82b cannot be inserted into the bearing portion 81b unless the opening / closing portion 82 is inclined at an angle of about 45 degrees or more to the right with respect to the perpendicular direction of the pedestal portion 81.

  The pedestal portion 81 is integrally formed with a locking claw 83 protruding forward, and a locking hole 84 as a claw receiving portion is formed on the opposite side of the support shaft of the opening / closing portion 82. Yes. The opening / closing part 82 is always closed, and the locking claw 83 can be operated in this closed state. That is, when the opening / closing part 82 is closed, the locking claw 83 is inevitably locked in the locking hole 84, and thus the closed state is maintained.

  In addition, an introduction port 85 for introducing a game ball guided from the upper plate 37 is provided at the front portion of the opening / closing unit 82, and the game ball is introduced downward from the introduction port 85. Note that a lid (not shown) as a case lid is detachably attached to the opening / closing part 82 constituting the case main body at the rear part (side facing the attachment part). A ball feed mechanism is disposed in the space.

  Although not shown, the ball feeding mechanism includes a ball guide path for stopping the game balls introduced from the introduction port 85 while aligning them, an electromagnet as a driving means for sending out the game balls one by one, and A feeding piece as a ball feeding member is provided. The delivery piece has a corner portion at one end pivotally supported so as to be rotatable with respect to the opening / closing portion 82, and on the opposite side, has a holder portion recessed so as to accommodate only one game ball. Yes. A metal piece made of magnetic metal is attached to the upper side portion connecting the holder portion and the rotation shaft so as to face the electromagnet. With this configuration, when the electromagnet is turned on, the metal piece is pulled so as to stick to the electromagnet, and the delivery piece rotates upward. Thereby, the game ball introduced from the introduction port 85 (game ball stopped on the ball guide path) is accommodated in the holder portion, and the downward flow of the game ball is restricted. On the other hand, when the electromagnet is turned off, the delivery piece rotates downward due to gravity, and the game ball accommodated in the holder part flows down to the base end part of the firing rail 73. It is guided. When the electromagnet is turned off, the upper part of the delivery piece restricts the flow of the next game ball to the holder part. Accordingly, by repeatedly executing the on / off operation of the electromagnet, the game balls are guided one by one to the firing start position. In addition, it is comprised so that on / off of an electromagnet and excitation / non-excitation of the launch device 72 (solenoid) may be synchronized.

  Returning to the description of FIG. 4, there is a predetermined gap between the firing rail 73 and the rails 58 and 59 (guide rail), and a foul ball passage 91 is formed below the gap. Therefore, if the game ball fired from the launching device 72 does not reach the return ball prevention member 61 and returns to the inside of the guide rail as a foul ball, the foul ball passes to the lower plate 31 via the foul ball passage 91. Discharged.

  4 is a payout passage (first payout passage) communicating with the upper plate 37, and the game ball is discharged to the upper plate 37 through the first payout passage 246. An openable / closable shutter 93 is attached to the first payout passage 246. Although detailed disclosure of the drawings is omitted, the shutter 93 can be rotated about the shaft portion provided along the lower side portion thereof, and the front frame set 14 is opened (state shown in FIG. 4). The shutter 93 substantially closes the first payout passage 246 by an urging force such as a spring. When the front frame set 14 is closed, the shutter 93 is pushed open by a ball passage rod 94 (see FIG. 2) provided on the back surface of the front frame set 14. Note that the game ball is discharged to the lower plate 31 in the open state of the front frame set 14. Therefore, as described above, in the pachinko machine 10 configured such that the upper plate 37 is directly provided on the front frame set 14, the game balls in the payout passage and the like are spilled off when the front frame set 14 is opened. Can be prevented.

  The resin base 40 is provided with small rectangular windows 95 and 96 at the lower left and right sides of the window hole 41. Accordingly, a seal or the like (for example, S1 in FIG. 7) stretched at the lower left and right corners of the game board 42 can be viewed through the small windows 95 and 96. It is also possible to affix the above-mentioned seal or the like from the small windows 95 and 96.

  The resin base 40 is provided with a substantially oval small window 97 at the upper left of the window hole 41, and a substantially oval hole 98 is provided at the upper left portion of the game board 42 corresponding to the small window 97. ing. Various electrical wirings (not shown) connected to an arcuate illumination part 112 of the front frame set 14 to be described later are led from the back side of the pachinko machine 10 through the small window 97 and the hole 98.

  Support metal fittings 101, 102, and 103 are attached to the left end portion of the inner frame 12 as support members for the front frame set 14 and the lower dish unit 13. The upper support bracket 101 is provided with a support hole 104 having a notch on the front side, and the middle support bracket 102 is provided with projecting shafts 105 and 106 protruding in the vertical direction. Further, the lower support fitting 103 is provided with a support hole (not shown).

  Next, the front frame set 14 will be described with reference to FIGS. FIG. 9 is a rear view of the front frame set 14. The front frame set 14 is formed with a substantially elliptical window 111 so that most of the game area can be visually recognized from the outside.

  Further, the shortest distance between the left end of the window 111 and the left end of the front frame set 14 as viewed from the front of the pachinko machine 10 (the left and right width of the left side frame portion: shown on the right side in FIG. 9), The frame width on the opening / closing axis side is set to be relatively large in order to increase the strength and support strength of the front frame set 14 itself. In this case, as is apparent from a comparison between FIGS. 1 and 4, in the state where the front frame set 14 is closed, a part of the left end portion of the outer rail 59 is covered by the left frame portion. Even if it becomes difficult to visually recognize the game ball in this way, it is only a passing point where the game ball is guided to the game area, and it is difficult to see the game ball in the game area where the player mainly enjoys the game. It doesn't mean. Therefore, there is no trouble in actual game. Moreover, while such a trouble does not arise, sufficient intensity | strength and support strength of the front frame set 14 are securable.

  In addition, the front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state at the time of big hit or predetermined reach. For example, an arcuate illumination part 112 containing a large number of light emitting means such as LEDs is provided on the periphery of the window part 111. In this pachinko machine 10, the arcuate lighting part 112 functions as an effect lamp such as a jackpot lamp or the like, and is turned on or flashing at the time of a jackpot or reach effect, so that it is a big hit or is reaching Inform the effect. In addition, on the left and right sides of the arcuate illumination part 112, there are provided a prize ball lamp 113 that is lit during the payout of a prize ball and an error display lamp 114 that is lit when a predetermined error occurs. Further, a small window 115 to which a transparent resin is attached is provided so as to be close to the lower end portion of the arcuate electric decoration portion 112 so that the inside can be visually recognized. In the present embodiment, chrome plating is applied in many regions on the surface side of the arcuate illumination part 112 in order to bring out more glamor.

  In addition, a ball lending operation unit 120 is disposed below the window 111, and the ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. If the ball lending operation unit 120 is operated in a state where a bill or a card is inserted into a card unit (ball lending unit) arranged on the side of the pachinko machine 10, a game ball is lent according to the operation. . The ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 37 as long as there is a remaining amount on the card or the like. Is done. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The frequency display unit 123 displays remaining amount information such as a card. It should be noted that the ball rental operation unit 120 is not necessary for a pachinko machine in which game balls are lent directly to the upper plate from a ball lending device or the like without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine is achieved.

  As shown in FIG. 9, a light emitting substrate 124 for the light emitting means is attached to the upper corner portion on the back side of the front frame set 14. Further, various reinforcing members made of metal are provided on the back side of the front frame set 14 so as to surround the window portion 111. Specifically, reinforcing metal plates 131, 132, 133, and 134 are attached to the back side of the front frame set 14 and on the upper and lower, left and right outer sides of the window portion 111, respectively. These reinforcing metal plates 131 to 134 are connected in contact with each other, but the light emitting substrate 124 is covered so as to avoid direct contact between the light emitting substrate 124 and the reinforcing metal plate 131. Alternatively, a resin part 135 for preventing energization of the light emitting substrate 124 is provided. As a result, generation of noise and magnetic field in the light emitting substrate 124 is suppressed.

  The right reinforcing sheet metal 131 in FIG. 9 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof. The engaging claw 131a is a hole in the inner frame 12 with the front frame set 14 closed. It is comprised so that it may engage with the part 12a (refer FIG. 4 etc.). With this configuration, the front frame set 14 is configured to include the upper plate 37, and even if the upper and lower pivot support positions are extended, the front frame set 14 can be prevented from being lifted at the intermediate position. Therefore, an illegal act or the like floating the front frame set 14 is suppressed.

As for the locking device G1 of this Embodiment, the attaching plate 187 is attached to the inner side of the inner frame 12 in the vertical direction.

  In addition, the various constituent members constituting the locking device G1, such as the sliding frame 191 including the base frame 18, are formed of a highly rigid cold-rolled steel plate (SPCC or the like), an electrogalvanized steel plate (SECC or the like), or the like. Yes.

  A plurality of mounting holes are formed in the mounting plate 187, and rectangular insertion holes 189 and 190 are formed in the upper and lower portions. Front frame set collars 14a and 14b (see FIG. 2) that extend to the back side of the front frame set 14 when the front frame set 14 is closed enter the insertion holes 189 and 190.

  Inside the support plate 188, a sliding rod 191 is slidably arranged up and down. The sliding rod 191 and the flange members 192 and 193 provided on the upper and lower portions of the base frame 186 are always pulled so as to be positioned at a lower position by a pair of upper and lower coil springs (not shown). The flange members 192 and 193 are slid in conjunction only when the sliding rod 191 moves upward. That is, each of the eaves members 192 and 193 can be independently moved upward, and when the upper and lower eaves members 192 and 193 are moved upward with a wire or the like (when an illegal act is performed). Must be hooked on both saddle members 192 and 193 and pulled up. That is, it is configured such that unauthorized unlocking cannot be performed only by hooking only one hook member 192 or 193 and pulling it upward.

  When the inner frame 12 is in the locked state (inner frame locked state), the hook members 192 and 193 are engaged with the claw horses 17 and 18 of the outer frame 11. In the configuration in which 193 moves integrally, when one of the heel members 192 and 193 comes into contact with the claw horses 17 and 18 due to manufacturing errors, assembly errors, etc., the other does not contact and rises. There is a risk that On the other hand, such problems can be solved by the movement of the flange members 192 and 193 independently. As a result, a ground path to be described later is more reliably formed.

  The eaves members 192 and 193 correspond to the inner frame engaging portions, and the pawl horses 17 and 18 correspond to the inner frame engaged portions.

  Further, the front frame set locking members 194 and 195 constituting the front frame set locking mechanism are formed by bending a metal plate into a U-shaped cross section, of which a rectangular engagement is provided on the surface on the mounting plate 187 side. Joint holes 194 a and 195 a are formed, and the engagement holes 194 a and 195 a are arranged to face the insertion holes 189 and 190 formed in the mounting plate 187. In addition, a pair of upper and lower coil springs (not shown) are provided between the front frame set locking members 194 and 195 and the mounting plate 187, and the front frame set locking members 194 and 195 are always pulled to be positioned at the upper position. ing.

  When the front frame set 14 is closed, the front frame set collars 14a and 14b enter the 194a and 195a. At this time, the front frame set locking members 194 and 195 are pushed by the flange portions 14a and 14b and slide downward once against the tensile force of the coil spring, and then the original force is applied by the tensile force of the coil spring. It returns to the position and engages with the front frame set collars 14a and 14b (front door locking state). Further, the front frame set locking members 194 and 195 slide downward as the sliding rod 191 slides downward during unlocking. As a result, the engagement between the front frame set collars 14a and 14b and the front frame set locking members 194 and 195 is released.

  The front frame set locking members 194 and 195 correspond to front door engaging portions, and the front frame set collar portions 14a and 14b correspond to front door engaged portions.

  A cam plate 196 a that is engaged with the sliding rod 191 is attached to the lock shaft of the cylinder lock 196. When the key is rotated in the clockwise direction in FIG. 12 by the key operation, the sliding rod 191 is slid upward. Thereby, the eaves members 192 and 193 are slid upward. At this time, the engagement between the eaves members 192 and 193 and the pawl horses 17 and 18 on the outer frame 11 side is released, and the inner frame 12 is unlocked (inner frame unlocked state).

  On the other hand, when the key is rotated counterclockwise in FIG. 12 by the key operation, the sliding rod 191 is slid downward, and the front frame set locking members 194 and 195 are slid downward. At this time, the engagement between the front frame set locking members 194 and 195 and the front frame set collars 14a and 14b on the front frame set 14 side is released, and the front frame set 14 is unlocked (front door unlocking).

At the same time, support hole portions 238 for the back pack unit are formed at two upper positions. Coaxial support holes are formed in the support hole portions 237 and 238, respectively. In addition, as shown in FIGS. 19 and 20, as an attachment mechanism for the second control board unit, the inner frame 12 has a pair of upper and lower fastening holes (nai latch holes) 239 at the lower left end portion from the game board installation area. Is provided. As a mounting mechanism for the back pack unit, the inner frame 12 is provided with a pair of upper and lower fastening holes (nylatching holes) 240 at the left end of the game board installation area. However, the support bracket for the second control board unit and the support bracket for the back pack unit can be provided as separate members. Reference numerals 241, 242, and 243 are rotational fixing tools for sandwiching and supporting the back pack unit 203 with the game board 42.

  In addition, in the rear configuration of the inner frame 12, a game ball for distributing a game ball paid out from a payout mechanism described later to any of the upper plate 37, the lower plate 31, or the discharge passage 218, at the lower right portion of the game board 42. A distribution unit 245 is provided.

  The opening 245a of the game ball distributing unit 245 communicates with the upper plate 37, the opening 245b communicates with the lower plate 31, and the opening 245c communicates with the discharge passage 218 (see FIG. 20). More specifically, as shown in FIG. 2, the resin base 40 is provided with a first payout passage 246 that allows the opening 245a of the game ball distribution unit 245 and the discharge port 37b of the upper plate 37 to communicate with each other. A second payout passage 247 that communicates the opening 245 b of the portion 245 and the discharge port 30 of the lower plate 31 is provided.

  Conventionally, since a portion corresponding to the game ball distribution unit 245 is provided on the back pack unit 203 side, the inner frame 12 and the game ball distribution unit are pressed by pushing the back pack unit 203 through the discharge port 37b of the upper plate 37. There was considered a fraudulent act in which a gap was formed between the part corresponding to H.245 and a wire or the like was inserted through the gap to operate the internal device. Therefore, in the pachinko machine 10, such illegal acts are prevented by providing the game ball distribution unit 245 on the inner frame 12 side and fixing the game ball distribution unit 245 by a fixing means. Further, the upper end surface of the game ball distributing unit 245 is formed in accordance with the height position where the lower end surface of the game board 42 is installed, and is devised so as not to prevent the removal of the game board 42.

  In addition, the game ball distribution unit 245 is made of an insulating resin material (for example, an ABS resin made of an antistatic material A described later) like the main body of the resin base 40, and the payout mechanism unit 352. The electrical connection between the (payout basket 359) and the upper plate 37 or the lower plate 31 is cut off. Further, as described above, since the game ball distribution unit 245 is not provided on the back pack unit 203 (payout mechanism unit 352) side, the electrical continuity is easily cut off structurally.

  Next, the first control board unit 201 will be described with reference to FIG. FIG. 22 is a front view of the first control board unit 201.

  The first control board unit 201 has a mounting base 251 having a substantially L shape, and the main control device 261 and the sound lamp control device 262 are mounted on the mounting base 251. Here, the main control device 261 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that stores necessary data according to the progress of the game, a port that communicates with various devices, and various lotteries. It has a main board including a random number generator used, a clock pulse generation circuit used for time counting and synchronization, and the main board is accommodated in a board box 263 made of a transparent resin material or the like. It is configured. The substrate box 263 includes a substantially rectangular parallelepiped box base and a box cover that covers the opening of the box base. The box base and the box cover are connected to each other by a sealing unit 264 (sealing means) so that the substrate box 263 is sealed.

  As the sealing unit 264 as the sealing means, any configuration can be applied as long as the box base and the box cover are connected so as not to be opened, but here, as shown in FIG. 22 and the like, five sealing members are connected. The box base and the box cover are connected so that they cannot be opened by inserting a locking claw into the long hole of the sealing member. The sealing process by the sealing unit 264 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation early and easily even if the unauthorized opening is performed. It is possible to perform the opening / sealing process again even after the operation. That is, the sealing process is performed by inserting the locking claw into the long hole of at least one sealing member among the five sealing members constituting the sealing unit 264. And when opening the board | substrate box 263 by the malfunction of the accommodated main board | substrate etc., the connection of the sealing member in which the latching claw was inserted, and another sealing member is cut | disconnected. Thereafter, when the sealing process is performed again, the locking claws are inserted into the long holes of the other sealing members. If the history of opening the board box 263 is left in the board box 263, it can be easily found that the illegal opening has been performed by looking at the board box 263.

  However, the main board is provided with terminal portions for connecting the connectors of the cable connectors, and the terminal portions are exposed from the board box 263. The exposure of the terminal portion is the same for other substrates and substrate boxes.

  A ball receiving portion 362 is provided at the left end, which is the upstream portion of the rail body 361. The ball receiving portion 362 allows the game ball that has dropped from the tank 355 to flow downstream due to its own weight, so that the game ball derived from the tank 355 can be smoothly taken into the rail body 361.

  In addition, the rail body 361 is provided with a partition wall 363 extending in the longitudinal direction, and the game balls are divided into two hands by the partition wall 363. The two ball passages partitioned by the partition wall 363 are slightly wider than the diameter of the game ball. In addition, although illustration is abbreviate | omitted, in the bottom face of each ball path partitioned off by the partition wall 363, the 1 line | wire or 2 line | wire protrusion is provided in order to improve the inductivity of a game ball or to suppress ball clogging. At the same time, an opening or the like is provided on the side of the protrusion to eliminate the ball clogging.

  A vibrator 360 for applying vibration to the tank rail 356 is attached to the back side of the tank rail 356. Therefore, if a clogged ball occurs near the tank rail 356, the clogged ball is eliminated by driving the vibrator 360.

  Further, as shown in FIG. 25, the rail body 361 is provided with a rectifying plate 367 so as to cover the ceiling portion of the downstream half. The rectifying plate 367 has a bow shape so as to limit the height of the ball passage in the tank rail 356 toward the downstream side, and a convex portion extending in the longitudinal direction is formed on the lower surface thereof. Thereby, each game ball flowing in the tank rail 356 finally flows out downstream without being stacked up and down. Therefore, even if a large group of game balls flow into the tank rail 356, the game balls are prevented from being bitten and the ball clogging in the tank rail 356 is eliminated. The rectifying plate 367 is detachably provided, and by removing the rectifying plate 367, maintenance in the tank rail 356 can be easily performed. Since the rectifying plate 367 is formed of a transparent polycarbonate resin, the situation inside the tank rail 356 can be confirmed without having to remove the rectifying plate 367 bothersomely. It can be omitted.

  The case rail 357 is disposed along the vertical direction on the side of the protective cover portion 354, and has a ball passage through which the game ball flows down.

  Further, the case rail 357 is provided with a ball break detection switch 357a. Thus, when the game balls are parked in the ball path of the case rail 357, the predetermined movable piece is pressed by the game balls, and the ball break detection switch 357a is turned on. On the other hand, when there is no game ball in the ball path, the ball break detection switch 357a is turned off.

  The case rail 357 is provided with a ball removal button 357b and a ball removal passage (not shown). The downstream side of the ball removal passage communicates with the discharge passage 218 via the game ball distributing unit 245, and when the ball removal of the tank 355 and the tank rail 356 is performed, the game ball passes through the ball removal passage. Is discharged outside the pachinko machine 10.

  The payout device 358 includes a payout motor 358a, a sprocket 358b, and a payout count switch 358c.

  The payout motor 358a is a stepping motor, and is configured to rotate the sprocket 358b once by giving a drive signal of 120 steps (pulses) in this embodiment. That is, the sprocket 358b is rotated by a rotation amount corresponding to the number of drive signals such that the sprocket 358b changes 45 degrees with a drive signal of 30 pulses. Then, the rotation amount of the payout motor 358a is controlled by this drive signal, and the payout number of game balls is controlled.

  In addition, a plurality of convex portions are provided at equal intervals on the peripheral surface of the sprocket 358b, and a ball receiving concave portion into which a game ball enters is provided between the convex portions. And sprocket 358b is arrange | positioned so that a convex part may protrude in the ball | bowl channel | path of the payout apparatus 358, and is rotationally driven by the payout motor 358a. Thereby, when the ball payout operation is stopped, the game balls are stopped in the ball passage, and during the ball payout operation, the sprocket 358b rotates in the clockwise direction (positive direction), and the game balls are paid out one by one. The sprocket 358b has slits formed at predetermined angular intervals (45 degrees in this embodiment, that is, 30 steps), and the amount of rotation of the sprocket 358b is detected by detecting the slit position by a photosensor (not shown). Can be detected.

  The payout count switch 358c is disposed on the downstream side of the sprocket 358b and detects a game ball paid out by the sprocket 358b. In the present embodiment, as the payout count switch 358c, a passing-type proximity sensor provided with a passing hole through which a game ball can pass is adopted. Of course, a photo sensor or the like may be used. Since the game balls are discharged one by one, the number of balls actually paid out can be grasped by counting the detection signal from the payout count switch 358c.

  Then, the payout motor 358a is driven to appropriately pay out a required number of game balls, and the payout game balls are detected by the payout count switch 358c and then guided to the game ball distribution unit 245 via the payout bar 359. Then, it is paid out to the upper plate 37 or the lower plate 31 via the game ball distributing unit 245.

  The payout bar 359 includes a first outlet passage 359a and a second outlet passage 359b. Here, the first lead-out passage 359a is configured to communicate the openings 245a and 245b of the game ball distribution unit 245 with the payout device 358. The second lead-out passage 359b is configured to communicate the opening 245c of the game ball distribution unit 245 with the ball removal passage of the case rail 357. Thereby, the game ball led out from the payout device 358 is led to the upper plate 37 and the lower plate 31 via the first lead-out passage 359a, and the game ball led out from the ball removal passage of the case rail 357 is 2 is discharged to the discharge passage 218 via the lead-out passage 359b and thus to the outside of the pachinko machine 10.

  Note that the first lead-out passage 359a of the payout basket 359 is formed so that the game ball is directed to the opening 245a of the game ball distribution unit 245. As a result, the game ball is guided to the upper plate 37 preferentially over the lower plate 31 at normal times. When the upper plate 37 and the first payout passage 246 leading to the upper plate 37 are filled with game balls, the opening 245a of the game ball distribution unit 245 is closed, so that the game balls paid out from the payout device 358 are: It spills down to the opening 245 b side of the game ball distribution unit 245, flows down to the second payout passage 247, and is guided to the discharge port 30 of the lower tray 31.

  Further, when the lower plate 31 is full and the game balls are accumulated up to a predetermined point in the second payout passage 247, the lower plate full tank detection switch (not shown) detects that fact (the lower plate full state) and the payout device 358 The payout of game balls is temporarily stopped.

  Thereafter, when the game balls in the lower plate 31 are extracted by a player or the like and the game balls accumulated in the second payout passage 247 begin to flow, the lower plate full tank detection switch is turned off, and the payout device 358 is turned on. It returns to the state where it can be paid out.

  As the game balls are paid out, the game balls stopped on the case rail 357, the tank rail 356, and the tank 355 flow toward the payout device 358 on the downstream side. When the number of game balls stored in the tank 355 decreases due to this flow, the island facility supply mechanism detects such a decrease in the number of stored balls and replenishes the tank 355 with the reduced amount of game balls.

  Returning to the description of FIGS. 24 and 25, the payout mechanism unit 352 is provided with a payout relay board 381 that relays a payout command signal from the payout control device 311 to the payout device 358. That is, the payout motor 358 a, the payout count switch 358 c, the lower pan full tank detection switch, and the like are electrically connected to the payout control device 311 via the payout relay board 381. Thus, the payout device 358 is driven and controlled based on the output signal from the payout control device 311 and the payout control device 311 counts the number of payouts based on the input signal from the payout count switch 358c.

  The payout mechanism 352 is provided with a power switch board 382 that takes in the main power from the outside. The power switch board 382 is connected to the power supply device 313 and supplies power to the power supply device 313. The power switch board 382 is supplied with, for example, an AC 24V main power supply via a voltage converter, and the power switch 382a is switched on or off by a switching operation of the power switch 382a.

  Now, it returns to description of the back pack 351 here. The back pack 351 is provided with a pair of upper and lower support shafts 385 at the right end in FIG. 24 and the like, and the back pack unit 385 is inserted into the support hole 238 shown in FIG. 203 is supported with respect to the inner frame 12 so that opening and closing is possible. Further, the back pack 351 is provided with a pair of upper and lower nai latches 386 as fasteners at the left end portion, and is provided with a locking hole 387 at the upper end portion. The nai latch 386 is inserted into the tightened hole 240 shown in FIG. At the same time, the backpack unit 203 is fixed to the inner frame 12 so as not to be opened and closed by locking the fixing member 242 shown in FIG. Further, in the present embodiment, a rotating I-type fastener is employed as the locking portion M8 in the vicinity of the tank 355 that stores a lot of game balls and is relatively loaded. For this reason, the back pack unit 203 (tank 355) can be more reliably locked as compared with the case where a fixing tool such as a ny latch is used. At this time, the back pack unit 203 is also fixed to the inner frame 12 by the fixtures 241 and 243 shown in FIG. The support hole portion 238 and the support shaft 385 are in the support shaft portion M6 in FIG. 18, the fastening hole 240 and the ny latch 386 are in the fastening portion M7, and the fixture 242 and the locking hole 387 are in the locking portion M8, respectively. Equivalent to. Further, the fixture 243 corresponds to the locking portion M9.

  Also, the base 353 of the back pack unit 203 is provided with an opening 391 for the external relay terminal plate 230, so that the external relay terminal plate 230 can be removed and operated even when the back pack unit 203 is fixed. It is possible.

  Next, the grounding structure of the pachinko machine 10, particularly the grounding structure of the part related to the payout of the game ball (the part where the game ball contacts) such as the payout mechanism 352 will be described in detail.

  The constituent members constituting the payout mechanism 352 in the present embodiment, that is, the tank 355, the tank rail 356, the case rail 357, the payout device 358, and the payout bar 359 are made of conductive materials mixed with carbon fiber (carbon fiber). It is made of a resin material.

  FIG. 27 shows molding materials and characteristics of the constituent members constituting the dispensing mechanism portion 352. As shown in FIG. 27, in this embodiment, the tank 355, the tank rail 356, the case rail 357, the dispensing device 358, and the dispensing basket 359 are made of conductive material made of ABS (acrylonitrile butadiene styrene) or PC (polycarbonate). A cover 359d that covers the payout basket 359 is formed of an antistatic material made of ABS (an insulating material made of ABS). In the present embodiment, a material having an electric resistance value per unit volume (hereinafter referred to as a surface resistance value) of 10 6 Ω or less is distinguished as a conductive material, and a material having a surface resistance value exceeding 10 6 Ω is distinguished as an antistatic material.

  The tank 355 is formed using a conductive material A made of ABS having a surface resistance value of 100Ω. In the tank 355, when the game ball is replenished from the supply mechanism of the game hall island facility in accordance with the payout of the game ball, the frequency of the replenished game ball colliding with the game ball stored in the tank 355 is low. In addition, since the contact area between the inside of the tank and the game ball is large, the amount of static electricity generated is considered to be particularly large. Furthermore, the game balls supplied to the tank 355 are often supplied in a state in which static electricity is charged, for example, by being polished by a game hall polishing device or colliding with other game balls in the middle of transportation. In addition, since the tank 355 is installed on the upstream side of the payout device 358 provided with a sensor such as a payout count switch 358c, the operation of the payout count switch 358c and the like is performed when the game ball flows down in a charged state. May be adversely affected. For this reason, in this embodiment, the conductive material A having a small surface resistance value is used for the tank 355.

  The tank rail 356 is formed using the same conductive material A as the tank 355. In the tank rail 356, in addition to the large contact area between the inside of the rail and the game ball, the game ball is replenished to the tank 355 from the island facility of the game hall without the game ball being stored in the tank 355. Since the supplied game balls may collide with the game balls stored in the tank rail 356, it is considered that the amount of static electricity generated is large. This possibility is particularly high at a position below the outlet 355b of the tank 355. In addition, the tank rail 356 is installed upstream of the payout device 358 including the payout count switch 358c and the like, like the tank 355. For this reason, in this embodiment, the conductive material A having a small surface resistance value is also used for the tank rail 356.

  The case rail 357 is formed using a conductive material C made of ABS having a relatively large surface resistance (103.8Ω) in consideration that the contact area with the game ball inside is smaller than the tank rail 356. In addition, the conductive material C is used instead of the antistatic material or the insulating material. In the unlikely event that a charged game ball flows down from the tank rail 356, the game ball enters the dispensing device 358 as it is. This is to prevent the static electricity from acting on the payout count switch 358c and the like.

  The payout device 358 is formed using a conductive material B made of PC having a surface resistance value (10 2 Ω) that is about the middle between the conductive material A and the conductive material C, including the portion where the payout count switch 358c and the like are provided. . The collision frequency of game balls in the payout device 358 and the contact area with the game balls are almost the same as those in the case rail 357, and the amount of static electricity generated in the payout device 358 is considered to be almost the same as in the case rail 357. On the other hand, the payout device 358 includes a payout count switch 358c and other components that control the number of payouts of prize balls and rental balls. Therefore, in the unlikely event that a charged game ball enters the payout device 358, It is necessary to reliably prevent the static electricity of the game ball from acting on the payout count switch 358c and the like. For this reason, in this embodiment, the conductive material B having a smaller surface resistance value than the case rail 357 is used for the dispensing device 358.

  Since the payout bar 359 is installed on the downstream side of the payout device 358 provided with the payout count switch 358c and the like, the conductive material having a relatively large surface resistance value is taken into consideration that the influence on the malfunction of the payout count switch 358c and the like is small. Molded using C. The reason why the conductive material C is used instead of the antistatic material or the insulating material is that a game ball as a prize ball or a rental ball is discharged to the upper plate 37 after removing static electricity in the discharge basket 359.

  On the other hand, the eaves cover 359d that covers the payout eave 359 is formed using an antistatic material A (1011Ω) made of ABS having a large surface resistance value. Considering that it is a portion that can be seen from the back side of the back pack unit 203, the collar cover 359d employs an insulating material or an antistatic material that has more types of material colors than the conductive material. Further, by forming the payout basket 359 and the coffin cover 359d combined with each other from materials having different surface resistance values (conductive material C, antistatic material A), the game balls flowing down in the payout basket 359 and the coffin cover 359d are charged. The static electricity is positively attracted to the dispensing basket 359 having a small surface resistance value. As a result, the payout relay board 381 provided on the back side of the heel cover 359d can be protected from static electricity.

  As shown in FIG. 27, the upper plate 37 is formed by using an antistatic material A having a large surface resistance, with a protruding portion 38 protruding from the front surface of the pachinko machine 10, and a small plate main body for storing game balls. It is molded using a conductive material A having a surface resistance value. Similarly, the lower plate 31 is formed by using an antistatic material A having a large surface resistance value at the overhanging portion 32 that projects to the front surface of the pachinko machine 10, and the plate body portion for storing the game balls has a small surface resistance value. The conductive material A is used for molding.

  In the upper plate 37 and the lower plate 31, game balls paid out from the payout device 358 frequently collide with the plate itself or game balls stored in the plate, and the contact area between the inside of the plate and the game balls is also large. The amount of static electricity is considered to be large. In addition, game balls in a state where static electricity is charged by colliding with other game balls in the middle of payout are often stored. The upper plate 37 and the like are located on the downstream side of the payout device 358. However, if the game balls stored here are left in a charged state, the upper plate 37 and the like are temporarily filled with the game balls, and the payout device 358 is filled. When game balls are accumulated from the top plate 37 to the upper plate 37, static electricity flows through the game balls to the payout device 358 on the upstream side, which may adversely affect the operation of the payout count switch 358c and the like. For this reason, in this embodiment, the electrically conductive material A with a small surface resistance value is used for the upper plate 37 and the lower plate 31 (plate main-body part).

  Next, the ground path (conductive path) of each part will be described. As shown in FIG. 25, a copper conductive plate 401 bent in a crank shape is disposed at the attachment position of the tank 355 and the tank rail 356 in the back pack 351. Then, by attaching the tank 355 and the tank rail 356 to the back pack 351, the tank 355 and the tank rail 356 are electrically connected via the conductive plate 401.

  In addition, a copper conductive plate 405 having a conductivity higher than that of the conductive resin material forming the tank 355 main body is attached to the side wall of the tank 355 on the attachment side (the back side in FIG. 25). The conductive plate 405 includes a main body 405a fitted into the side wall of the tank 355, and a lead wire (covered wire in which a copper wire is covered with an insulating material) 405b connected to one end of the main body 405a.

  The main body 405a is long in the left-right direction and has a substantially U-shaped cross section. And, at the time of mounting, it is fitted from above so as to straddle the side wall of the tank 355, a part thereof faces the inside of the tank 355, and a structure that directly contacts a game ball stored in the tank 355 over a wide range. It has become.

  When the back pack 351 is attached to the inner frame 12 (see FIG. 17), the ring-shaped connection terminal 405c provided on the leading end side of the lead wire 405b is connected to the base frame 186 (attachment plate 187) of the locking device G1. Are screwed to a connecting portion 187a (see FIG. 19 and the like) provided in the vicinity of the upper end portion.

  Further, as shown in FIG. 25, a copper conductive plate 409 is attached to the back surface side of the base portion 353 on the rotating shaft side of the back pack 351. The tank rail 356, the case rail 357, the dispensing device 358, and the dispensing basket 359 are attached so as to contact the conductive plate 409. Accordingly, the tank rail 356, the case rail 357, the dispensing device 358, and the dispensing basket 359 are electrically connected via the conductive plate 409.

  With the above configuration, the tank 355, the tank rail 356, the case rail 357, the dispensing device 358, the dispensing rod 359, and the locking device G1 are electrically connected.

  Further, as shown in FIG. 17, a connecting portion 11g for screwing the ground wire is provided on the back side of the right side frame constituting portion 11d of the outer frame 11. When the pachinko machine 10 is installed in the island facility of the game hall, the other end side of a predetermined ground wire whose one end is connected to the external ground of the island facility is connected to the connection portion 11g by a screw or the like. . Thereby, the pachinko machine 10 is in a state of being grounded to the outside.

  That is, when the inner frame 12 is locked with respect to the outer frame 11, the hook members 192, 193 of the locking device G 1 are engaged with the pawl horses 17, 18 of the outer frame 11, so that the payout mechanism 352 is externally attached. It is in a state of being electrically connected to the ground. That is, the payout mechanism 352 (tank 355) → conductive plate 405 → locking device G1 [base frame 186 → sliding bar 191 → claw member 192 (193)] → claw horse 17 (18) → outer frame 11 (right side frame configuration) 11d) → Earth wire → Earth path such as an external ground of the island facility is formed, and the static electricity removed from the dispensing mechanism 352 is discharged and removed to the outside of the machine through the ground path.

  Further, as shown in FIG. 24, the payout mechanism portion 352 is divided from the upstream side as follows according to the magnitude of the surface resistance value of each component portion. Region P (region from tank 355 to tank rail 356) made of conductive material A having a surface resistance value of 100Ω, region Q (case rail 357 region) made of conductive material C having a surface resistance value of 103.8Ω, surface resistance value Are a region R (dispensing device 358 region) made of a conductive material B of 10 2 Ω and a region S (dispensing rod 359 region) made of a conductive material C having a surface resistance value of 103.8 Ω.

  Under the above configuration, when game balls are stored in the region P, the region Q, and the region R and are charged with static electricity, the static electricity is more easily removed in the region Q than in the region R and in the region P than in the region Q. .

  Next, the ground path (conductive path for the ball tray) of the lower plate 31 and the upper plate 37 will be described. As described above, the lower plate 31 and the upper plate 37 are electrically connected to the reinforcing metal plates 28 and 134, respectively. Accordingly, when the lower plate unit 13 is locked, the lower plate 31 → the reinforcing sheet metal 28 → the engaging portions 13a and 13b → the locking device G1 [the lower plate unit collar portions 197a and 197b → the base frame 186 → the sliding rod 191 → claw member 193 (192)] → claw horse 18 (17) → outer frame 11 (right side frame constituting part 11d) → earth wire → outer ground of the island facility is formed, and the lower plate is formed via the earth path. The static electricity removed from 31 is discharged out of the apparatus.

  Similarly, when the front frame set 14 is locked, the upper plate 37 → the reinforcing sheet metal 134 → the reinforcing sheet metal 132 → the front frame set collar 14b (14a) → the locking device G1 [the front frame set locking member 195 (194 ) → Sliding rod 191 → 鉤 member 193 (192)] → claw horse 18 (17) → outer frame 11 (right side frame constituting portion 11d) → earth wire → external grounding of island equipment is formed, and the earth The static electricity removed from the upper plate 37 through the path is discharged and removed outside the apparatus.

(Similar) is an area for storing stack pointers, values of registers, I / O, and the like. Writing to the backup area 503a is executed when the power is turned off by NMI interrupt processing. Conversely, restoration of each value written to the backup area 503a is performed when power is turned on (including power-on due to power failure cancellation, and so on). It is executed in electric processing. Note that a power failure signal SK1 output from a power failure monitoring circuit 542, which will be described later, is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 501 when a power failure occurs due to the occurrence of a power failure or the like.

  The RAM 513 of the payout control device 311 is configured to hold (backup) data by supplying a backup voltage from the power supply device 313 even after the pachinko machine 10 is turned off, like the RAM 503 of the main control device 261 described above. The RAM 513 is provided with a backup area 513a in addition to a memory and an area for temporarily storing various data.

  The backup area 513a has a stack pointer, each register at the time of power off, each register, so that the power of the pachinko machine 10 is restored to the state before the power is turned off when the power is turned off. This is an area for storing values such as I / O. The writing to the backup area 513a is executed when the power is turned off by the NMI interrupt processing, and conversely, the restoration of each value written to the backup area 513a is executed in the power recovery processing when the power is turned on.

  An input / output port 515 is connected to the CPU 511 incorporating the ROM 512 and the RAM 513 through a bus line 514 including an address bus and a data bus. A RAM erase switch circuit 543, a main control device 261, a firing control device 312, a payout motor 358a, and the like are connected to the input / output port 515, respectively.

  The launch control device 312 permits or prohibits the launch of the gaming machine by the launch device 72, and the launch device 72 and the ball feeding unit 74 are permitted to drive when predetermined conditions are met. Specifically, it is detected by a sensor signal that a firing permission signal is output from the payout control device 311, that the player is touching the handle 35, and a firing stop switch for stopping the firing. The launching device 72 and the ball feeding unit 74 are driven on the condition that the is not operated, etc., and the game balls are launched one by one with the strength corresponding to the operation amount of the handle 35.

  The power supply unit 313 includes a power supply unit 541 for supplying power to each part of the pachinko machine 10, a power failure monitoring circuit 542 for monitoring power interruption due to a power failure, and a RAM erase switch connected to the RAM erase switch 323. A circuit 543. The power supply unit 541 supplies necessary operation power to the main control device 261, the payout control device 311 and the like through a power supply path (not shown). As its outline, the power supply unit 541 takes in an AC 24 volt power supply supplied from the outside, and generates a + 12V power supply for driving various switches and motors, a + 5V power supply for logic, a backup power supply for RAM backup, and the like. Then, these + 12V power supply, + 5V power supply and backup power supply are supplied to the main control device 261, the payout control device 311 and the like. Note that operation power (+12 V power, +5 V power, etc.) is supplied to the launch control device 312 via the payout control device 311.

  The power failure monitoring circuit 542 is a circuit for outputting a power failure signal SK1 to each NMI terminal of the CPU 501 of the main control device 261 and the CPU 511 of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541, and determines that a power failure (power failure) has occurred when this voltage is less than 22 volts. The power failure signal SK1 is output to the main controller 261 and the payout controller 311.

When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs a RAM erase signal SK2 to the main controller 261 and the payout controller 311. When the power of the pachinko machine 10 is turned on with the RAM erase switch 323 pressed (including power-on due to power failure cancellation), the data in the respective RAMs 503 and 513 are cleared in the main controller 261 and the payout controller 311. The

  As described in detail above, according to the present embodiment, the tank 355 and the tank rail 356 are formed using the conductive material A made of ABS having a surface resistance value of 100Ω. On the other hand, the dispensing device 358 is formed using a conductive material B having a surface resistance value (10 2 Ω) larger than that of the conductive material A, and the case rail 357 has a conductive material C having a surface resistance value (103.8Ω) larger than that of the conductive material B. It is molded using. As a result, in the tank 355 and the tank rail 356 where the game ball is easily charged with static electricity, the static electricity can be efficiently removed immediately after the occurrence of static electricity and at a position as far as possible from the dispensing device 358. It is possible to suppress the static electricity generated in the case of flowing downstream. As a result, it is possible to suppress the occurrence of various problems associated with electrostatic discharge, such as prevention of malfunction of the dispensing device 358.

  In addition, in the present embodiment, the tank 355, which is easily charged with static electricity in the game ball, is provided as a starting point with an earth path for electrical connection with an external earth outside the pachinko machine 10, so that the upstream of the tank 355 and the tank rail 356 is provided. The static electricity removed from the part can be prevented from flowing downstream. As a result, the above effects can be made more reliable.

  Furthermore, as shown in FIG. 29, the conductive plate 405 made of copper having relatively good conductivity is attached to the tank 355 and directly contacted with the game ball to remove the static electricity, so that the static electricity can be removed more efficiently. .

  In the present embodiment, the locking device G1 and the right side frame constituting portion 11d of the outer frame 11 are used as a part of the ground path. Thereby, since it is not necessary to use an earth wire as much as possible, extra wiring on the back side of the pachinko machine 10 can be reduced, and the complexity of wiring and the increase in the number of parts can be suppressed.

  Furthermore, since it is possible to achieve electrical continuity with the external ground of the island facility through a position farther from various electronic devices disposed in the central portion on the back side of the pachinko machine 10, electromagnetic induction noise to various electronic devices, etc. Etc. can be suppressed as much as possible. In the present embodiment, as shown in FIG. 20, an insulating partition wall 244 is provided that separates the central portion on the back side of the inner frame 12 where various electronic devices are disposed and the position where the locking device G1 is disposed. Therefore, it is possible to suppress static electricity from flowing to the back central portion side (various electronic device sides) of the pachinko machine 10.

  In the present embodiment, the pachinko machine 10 and the island facility are connected to each other because the electrical connection with the outside of the pachinko machine 10 can be achieved through the outer frame 11 that is always fixed to the island facility and does not open and close. It is possible to suppress the occurrence of problems such as the ground wire hindering the opening / closing operation of the inner frame 12, or the ground wire being damaged / disconnected with the opening / closing operation of the inner frame 12. As a result, it is easy to maintain a good electrical conduction state of the ground path.

  Further, in this embodiment, the ground members of the components of the payout mechanism 352, that is, the tank 355, the tank rail 356, the case rail 357, the payout device 358, and the payout bar 359 are all connected to the most upstream tank 355 → It is configured to be performed via a ground path such as the locking device G1 → the outer frame 11. That is, the ground connection is not made via the support fitting 235 or the like that supports the back pack unit 203. The support bracket 235 that supports the back pack unit 203 having the payout mechanism 352 that stops the game ball and becomes very heavy is subjected to a very large load. There is a risk that the electrical continuity will deteriorate. On the other hand, the hook members 192 and 193 of the locking device G1 and the claw horses 17 and 18 of the outer frame 11 are not so heavily loaded with the opening and closing of the inner frame 12, and the support metal 235 is electrically affected by friction or the like. Since the deterioration of the conduction state is unlikely to occur, according to the present embodiment, it is easy to maintain a good electrical conduction state of the ground path.

  In this embodiment, the upper plate 37 is also formed using the ABS conductive material A having a surface resistance value of 100Ω. Thereby, a game ball is paid out from the payout mechanism 352, and the static electricity is efficiently removed at a position as far as possible from the payout device 358 immediately after the occurrence of static electricity in the upper plate 37 where the game ball is easily charged with static electricity. It is possible to prevent static electricity generated in the upper plate 37 and the like from flowing toward the dispensing mechanism portion 352. As a result, it is possible to suppress the occurrence of various problems associated with electrostatic discharge, such as prevention of malfunction of the dispensing device 358.

  In addition, in the present embodiment, the electrical continuity between the upper plate 37 and the payout mechanism portion 352 (the payout basket 359) is interrupted by the insulating game ball distribution unit 245, and the downstream side of the upper plate 37 is the starting point. By providing the ground path for establishing electrical continuity with the external ground outside the pachinko machine 10, it is possible to suppress the static electricity removed from the upper plate 37 from flowing to the upstream side and thus to the payout mechanism portion 352. As a result, the above effects can be made more reliable.

  In place of the present embodiment, the upper plate 37 is connected to the ground via the support brackets 181 and 182 of the front frame set 14 and the support brackets 101 and 102 on the inner frame 12 side for supporting the same. In such a case, there is a risk that the electrical continuity in the connection portions of the support fittings 181, 182 and the like is deteriorated due to friction or the like accompanying opening and closing of the front frame set 14. On the other hand, in the present embodiment, the ground connection of the upper plate 37 is also performed via the locking device G1 and the like as in the case of the payout mechanism portion 352. Easy to maintain state.

  Furthermore, the electrical connection between the front frame set 14 side and the inner frame 12 side through the locking device G1 or the like prevents the ground wire from obstructing the opening / closing operation of the front frame set 14, It is possible to suppress the occurrence of problems such as damage or disconnection of the ground wire due to the opening / closing operation. As a result, it is easy to maintain a good electrical conduction state of the ground path.

  Further, in the present embodiment, the lower tray unit 13 in which the lower tray 31 and the handle 35 are provided on the front side and the electrical wiring DH1 and the like of the handle 35 are disposed on the rear side, and the game ball more frequently than the lower tray 31. Is provided separately from the front frame set 14 provided with the upper plate 37 that is easily discharged and is likely to generate static electricity. For this reason, structurally, it is easy to cut off the direct electrical continuity between the front frame set 14 and the lower tray unit 13, and static electricity removed from the upper tray 37 is applied to various electrical devices and the like via the electrical wiring DH 1 and the like. The influence can be reduced.

  Since the locking device G1 and the right side frame constituting portion 11d of the outer frame 11 are disposed in a relatively wide range (substantially range) in the vertical direction of the pachinko machine 10, the upper plate 37, the lower plate 31, the tank 355, etc. Therefore, it is possible to easily connect to the ground from any height member.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above-described embodiment, the various metal members such as the hinge metal members 15 and 16, the claw horses 17 and 18, the reinforcing metal plate 28 and the like, and the locking device G1 are cold-rolled steel plates (SPCC and the like), It is formed of an electrogalvanized steel sheet (SECC or the like). These metal members may be formed of other metal materials as long as they are metal materials having relatively high rigidity and conductivity.

  However, as shown in FIG. 29, since zinc is more conductive than iron or the like, a configuration using an electrogalvanized steel sheet can construct a ground path with better conductivity, and can prevent static electricity. It can be removed more smoothly.

  (B) In the above embodiment, each component of the payout mechanism 352, that is, the tank 355, the tank rail 356, the case rail 357, the payout device 358, and the payout bar 359 are made of a conductive resin material mixed with carbon fiber. Is formed. However, the present invention is not limited thereto, and these constituent members may be formed of a conductive resin material containing a metal material such as stainless fiber. Of course, the same applies to the upper plate 37 and the lower plate 31.

  (C) In the said embodiment, the hybrid type outer frame 11 in which the left side frame structure part 11c and the right side frame structure part 11d were comprised with the extrusion molding material made from aluminum alloy is illustrated. The outer frame 11 is not limited to this. For example, at least the right side frame constituting part 11d corresponding to the locking device G1 may be of an aluminum alloy type, or all the frame constituting parts 11a to 11d. May be of a type made of an aluminum alloy.

  Of course, the left side frame constituting part 11c and the right side frame constituting part 11d do not have to be extrusion molded products, and may be, for example, molded products.

  Further, regarding the forming material, not only the aluminum alloy but also other metal materials having conductivity may be used. However, aluminum, which is the main component of the aluminum alloy, is more preferable to use an aluminum alloy because it is more conductive than iron and the like as shown in FIG. The aluminum alloy is formed by adding aluminum, zinc, magnesium, copper, nickel, titanium, silicon, or any combination thereof.

  In order to prevent static electricity from flowing to unintended locations on the island facility, the upper frame component 11a and the lower frame component 11b fixed to the island facility with nails or the like are insulated from the wooden member of the above embodiment. It is more preferable to use a hybrid type made of a conductive member.

  (D) Various ground paths are not limited to the above embodiment.

  With regard to the payout mechanism 352, for example, a ground path (tank 355 → ground wire → external ground of the island facility) in which the tank 355 and the external ground of the island facility are directly connected by the ground wire, or the rotating shaft side of the back pack unit 203 Earth path (tank 355 → earth wire etc. → support shaft 385 → support bracket 235 → earth wire → external earth of island equipment), earth route (tank 355 → earth wire etc. → support shaft) through the left side frame component 11c 385 → support metal fitting 235 → earth wire etc. → support metal fittings 65, 66 → hinge metal fittings 15 and 16 → left side frame component 11c → earth wire → external earth of island equipment), earth path via the earth terminal of the power supply device 313 etc. Tank 355 → ground wire, etc. → power supply device 313 → ground wire → external ground of island facility). Of course, the locking device G1 may be used as a part of these ground paths. For example, an earth path such as tank 355 → locking device G1 → earth wire etc. → earth terminal of power supply device 313 etc. → earth wire → external earth of island facility may be adopted.

  Similarly, with respect to the upper plate 37 and the lower plate 31, for example, a ground path that passes through the rotating shaft side of the front frame set 14 and the lower plate unit 13 [upper plate 37 (lower plate 31) → support brackets 181, 182 (support portion 183, 184) → support metal fittings 101, 102 (support metal fittings 102, 103) → earth wire etc. → earth terminal of power supply 313 etc. → earth wire etc. → external earth of island facility], earth via left side frame component 11c Path [upper plate 37 (lower plate 31) → support brackets 181, 182 (support portions 183, 184) → support brackets 101, 102 (support brackets 102, 103) → support brackets 65, 66 → hinge brackets 15, 16 → left side Frame component 11c → ground wire → external ground of island equipment], ground path via ground terminal of power supply device 313 etc. (upper plate 37 and lower plate 31 → locking device G1 → ground wire etc. → power supply device 313 etc. Over the pin w → external ground of the ground wire → island equipment), and the like.

  The ground connection destination outside the pachinko machine 10 is not limited to the external ground of the island facility, and may be a card unit, for example.

  In addition, for example, the right side frame constituting part 11d of the outer frame 11 may not be connected to the ground connection destination outside the pachinko machine 10, and the right side frame constituting part 11d itself may function as a predetermined ground part. The electrical continuity between the locking device G1 and the right-side frame component 11d is interrupted by interposing an insulating resin member between the frame component 11d and the claw horses 17 and 18, and the locking device G1 itself. May be configured to function as a predetermined ground portion. Of course, both the locking device G1 and the right side frame constituting part 11d may be configured to function as a ground part.

  (E) The electrical connection means for electrically connecting various members is not limited to the above embodiment. For example, the tank 355 and the locking device G1 may be configured to be electrically connected via a metal plate. Alternatively, the upper plate 37 and the reinforcing sheet metal 134 may be electrically connected using a ground wire. The tank 355 and the tank rail 356 may be in direct contact with each other. Further, a configuration in which a relay member such as the conductive plate 405 is omitted may be employed.

  (F) The conductive material constituting the various members is not limited to the above embodiment.

  For example, in the above embodiment, the conductive material A having the same surface resistance value is used for the tank 355 and the tank rail 356, but a conductive material having different surface resistance values may be used for the tank 355 and the tank rail 356. For example, the tank 355 may be configured using a conductive material having a smaller surface resistance than that of the conductive material used for the tank rail 356.

  In the above embodiment, the tank rail 356 and the case rail 357 are made of conductive materials having different surface resistance values. For example, the tank rail 356 and the case rail 357 are made of conductive materials having the same surface resistance value. It is good also as the structure used.

  Moreover, in the said embodiment, the electrically conductive material B whose surface resistance value is smaller than the case rail 357 is used for the dispensing device 358. This is because the collision frequency between game balls in the payout device 358 and the contact area with the game balls are almost the same as the case rail 357, and the amount of static electricity generated in the payout device 358 is almost the same as that in the case rail 357. However, it is considered that the payout count switch 358c and the like are provided. Therefore, in consideration of the fact that the case rail 357 is also an upstream member of the dispensing device 358, it is preferable to use a conductive material having a smaller surface resistance than the conductive material used for the dispensing device 358.

  Moreover, in the said embodiment, although it becomes the structure which used the electrically conductive material of a different surface resistance value for the upper plate 37 and the lower plate 31, and the discharge basket 359, the same surface is used for the upper plate 37 and the discharge basket 359, for example. It is good also as a structure using the electrically conductive material of resistance value.

  (G) In the above embodiment, the tank 355 is a specific part that is a connection point on the side of the payout mechanism part 352 that is electrically connected to a predetermined ground part such as an external ground of the island facility. For example, the tank rail 356 and the locking device G1 may be electrically connected. Further, both the tank 355 and the tank rail 356 may be electrically connected to the locking device G1.

  Note that, when the tank rail 356 is connected to the ground, the position on the upstream side (left side in FIG. 26) from the position H2 (see FIG. 26) at the boundary between the bottom 355a and the outlet 355b of the tank 355 in the left-right direction. For example, it is preferable that the ball receiving unit 362 be grounded. Since the boundary between the bottom 355a and the outlet 355b is a position where the game ball falls on the tank rail 356, static electricity is likely to occur. Therefore, by providing a ground path starting from a specific part upstream from this point, static electricity hardly flows to the downstream side of the dispensing mechanism 352.

  Moreover, in the said embodiment, the specific site | part used as the connection point by the side of the top plate 37 electrically connected with the external earth | ground of island facilities is a downstream site | part from the starting point (specific position of a ball tray) H1 of the rectification | straightening part 37d. It has become. For example, the upstream portion of the upper plate 37 may be a connection point.

  (H) Each component of the payout mechanism 352 such as the tank 355 is plated with a material (for example, copper) that has a close relationship with iron (steel), which is the material of the game ball, on the charge train, A configuration in which static electricity is hardly generated by contact between the tank 355 and the game ball may be employed. Of course, the same applies to the upper plate 37 and the lower plate 31.

  (I) In the above embodiment, the back pack unit 203 on which the payout mechanism portion 352 is mounted is configured to be rotatable on the back side of the inner frame 12, but this is not limiting, and the back pack unit 203 is not limited to the inner frame. It is good also as a structure fixed to the 12 back side.

  (J) In the above embodiment, the constituent members of the payout mechanism 352, that is, the tank 355, the tank rail 356, the case rail 357, the payout device 358, and the payout bar 359 are all electrically connected, and the most upstream side This is connected to the outside of the pachinko machine 10 through a tank 355.

  For example, the tank 355 and the tank rail 356 may be insulated from each other, or the tank rail 356 and the case rail 357 may be insulated so that static electricity does not easily flow to the downstream side of the dispensing mechanism 352. Good.

  In the configuration in which the tank 355 and the tank rail 356 are insulated, for example, the tank 355 is grounded to the external ground of the island facility via the locking device G1, and the remaining tank rail 356, case rail 357, dispensing device 358, and The payout bar 359 may be connected to the external ground of the island facility via a support metal fitting 235 that supports the back pack unit 203 or the like. Alternatively, the tank 355 and the tank rail 356 may be grounded via the locking device G1, and the remaining case rails 357 and the like may be grounded via the support bracket 235 and the like. Similarly, in the configuration in which the tank rail 356 and the case rail 357 are insulated, the tank 355 and the tank rail 356 are grounded via the locking device G1, and the remaining case rail 357 and the like are grounded via the support bracket 235 and the like. It is good also as a connected structure.

  Examples of the insulating means include a configuration in which the constituent members are separated, and a configuration in which an insulating member such as rubber is interposed between the constituent members.

  (K) The configuration of the locking device G1 is not limited to the above embodiment, and a different configuration may be adopted. For example, in the above-described embodiment, regarding the locking mechanism of the front frame set 14, front frame set collars 14a and 14b having claw portions are provided on the front frame set 14 side, and the claw portions are engaged on the locking device G1 side. Front frame set locking members 194 and 195 to be combined are provided, but a hook member having a claw portion is provided on the locking device G1 side, and a receiving portion that engages with the claw portion is provided on the front frame set 14 side. It is good.

  (L) In the above embodiment, the upper plate 37 is provided in the front frame set 14, and the lower plate 31 is provided in the lower plate unit 13. For example, the front frame set 14 and the lower plate unit 13 are provided integrally, and the upper plate 37 and the lower plate 31 are provided separately, or the front frame set 14 and the lower plate unit 13 are provided separately. Are provided integrally, and the upper plate 37 and the lower plate 31 are integrally provided (including a configuration in which the lower plate 31 is omitted and only the upper plate 37 is provided), the upper plate 37 and the lower plate 31 are provided. A configuration in which the lower plate unit 13 is provided integrally, a configuration in which the upper plate 37 and the lower plate 31 are provided in the lower plate unit 13, and the upper plate 37 and the lower plate 31 are provided separately. May be adopted.

  (M) In the above embodiment, the connecting portion 11g for screwing the ground wire is provided at the lower part of the back side of the right side frame constituting portion 11d of the outer frame 11. The position and the number of the connecting portions 11g are not limited to this. For example, it is good also as a structure which provided the connection part in the upper part of the right side frame structure part 11d. In this way, the ground path from the tank 355 to the external ground of the island facility can be further shortened.

  Further, the form of the connecting portion is not limited to the above embodiment, and for example, the flange portion on the rear side of the right side frame constituting portion 11d may be used as the connecting portion. In such a case, it is possible to employ a configuration in which the terminal portion of the ground wire extending from the external ground of the island facility is attached so as to sandwich the flange portion of the right side frame constituting portion 11d. In this way, the connection position can be freely changed in the vertical direction, and convenience is increased.

  (N) You may implement as a pachinko machine of a different type from the above-mentioned embodiment. In addition to pachinko machines, various game machines such as an arrangement ball machine and a sparrow ball similar thereto may be used. Furthermore, as a gaming machine other than a pachinko machine, it can of course be implemented as a gaming machine in which a pachinko machine and a slot machine are integrated.

  Hereinafter, the technical idea that is not described in the claims and that can be grasped from the above embodiment will be described together with the effects thereof.

Means 1. A tank capable of storing game balls;
A payout device for paying out game balls;
A gaming machine comprising a payout mechanism having a guide rail for guiding a game ball from the tank to the payout device,
While forming the tank, the guide rail and the dispensing device using a resin conductive material,
The resistivity of the conductive material used for forming the tank and the guide rail is a resistivity lower than the resistivity of the conductive material used for forming the dispensing device,
Electricity between a specific portion upstream of the specific position of the payout mechanism portion and a predetermined ground portion without passing through a component portion downstream of the specific position of the guide rail of the payout mechanism portion. A gaming machine characterized by having a conductive path (ground path) for achieving continuous conduction.

  Here, the resistivity means an electric resistance value per unit volume of a certain material. The resistivity can be expressed as the reciprocal of the specific conductivity.

  According to the above means 1, the tank, the guide rail and the dispensing device constituting the dispensing mechanism are formed using the resin conductive material, and the resistivity of the conductive material used for forming the tank and the guide rail is dispensed. The resistivity is lower than the resistivity of the conductive material used for forming the device. Therefore, in the situation where game balls are accumulated from the payout device to the tank via the guide rail, when static electricity charged in the game balls is discharged, the discharge is probable to occur on the upstream side (tank side). It is less likely to occur on the downstream side (dispensing device side). This makes it possible to quickly remove static electricity as soon as possible after the occurrence of static electricity and at a position as far as possible from the dispensing device in the upstream part of the tank or guide rail where the game ball is easily charged with static electricity. It is possible to suppress the static electricity that has flown to the downstream side (dispensing device side). As a result, it is possible to suppress the occurrence of various problems associated with electrostatic discharge, such as prevention of malfunction of the dispensing device.

  In addition, a tank that easily charges static electricity on the game ball and a conductive path that establishes electrical connection between the upstream portion of the guide rail and a predetermined ground portion without having to go through a component downstream of the specific position of the guide rail are provided. Thus, static electricity removed from the upstream portion of the tank and the guide rail can be prevented from flowing to the downstream side (dispensing device side). As a result, the above effects can be made more reliable.

  Examples of the “predetermined ground portion” include an external ground outside the gaming machine, a ground terminal of a power supply device, various metal members (such as “locking device” and “outer frame”), and the like. Since the “locking device” and the “outer frame” have a relatively large capacity, when a relatively small amount of static electricity flows, the static electricity is naturally discharged. That is, even in a configuration in which the “locking device”, the “outer frame”, and the like are not connected to the external ground outside the gaming machine, the “locking device” and the “outer frame” themselves function as the ground portion.

Mean 2. A rectangular frame-shaped outer frame fixed to an island facility having a supply mechanism for supplying game balls;
An inner frame supported on the left and right sides (for example, the left side) of the outer frame so as to be openable and closable with the vertical direction as a pivot axis
A gaming machine provided with the payout mechanism on the back side of the inner frame,
The tank is configured to store a game ball supplied from the supply mechanism at the upper back of the inner frame,
The payout device is disposed closer to the rotating shaft side of the inner frame,
The guide rail includes an upstream rail member (tank rail) that causes game balls led out from the tank to flow downward from the other side (for example, the right side) to the left side or the right side while aligning the game balls, and the upstream side. The gaming machine according to claim 1, further comprising a downstream rail member (case rail) that allows the rail member to communicate with the payout device.

Means 3. A locking device is provided along the vertical direction on the other left and right sides of the inner frame, and includes a locking device having an inner frame locking mechanism for locking the inner frame to at least the outer frame,
The locking device is formed using a metal conductive material,
By establishing electrical continuity between the tank or the upstream rail member, which is the specific part, and the locking device,
The gaming machine according to means 2, wherein the locking device functions as a part of the conductive path or the predetermined ground portion.

  According to the above means 3, the ground wire is used as much as possible by using the locking device as a part of the conductive path for discharging and removing the static electricity charged in the game ball in the tank or the like to the outside of the game machine or as a predetermined ground part. No need. Moreover, since the existing locking device can be utilized, the increase in a number of parts can be suppressed.

  Conventionally, on the back side of gaming machines such as pachinko machines, in addition to a payout mechanism portion for paying out game balls, various control devices for performing various controls relating to games have been arranged. A cable connector for command transmission / reception that electrically connects the power supply and a cable connector for power supply that electrically connects the control device and the power supply device are also wired.

  For this reason, when the ground wire is connected to the upstream portion of the tank or the upstream rail member to form the conductive path, the ground wire is disposed so as to straddle various control devices, cable connectors, and the like. There is a concern about the influence (indirect ESD) of electromagnetic induction noise or the like from the ground wire to various electronic devices.

  In this respect, since the locking device is normally disposed along the side edge of the inner frame away from the various electronic devices at the center on the back side of the gaming machine, according to this means, The influence on electronic equipment can be suppressed as much as possible. Furthermore, if an insulating partition wall is provided that separates the central portion on the back side of the inner frame on which various electronic devices are disposed and the position on which the locking device is disposed, static electricity will be generated on the rear central portion side of the gaming machine (various electronic components). It is also possible to suppress the flow to the device side).

  In addition, if an earth wire is connected to the upstream portion of the tank or the upstream rail member, and the various electric devices arranged in the center on the back side of the gaming machine are to be bypassed, A long, relatively long ground wire is required.

  In this respect, according to the present means, it is not necessary to route a long section of the ground wire, and extra wiring on the back side of the gaming machine can be reduced, so that the wiring on the back side of the gaming machine can be suppressed from becoming complicated. .

Means 4. The locking device is
Inner frame locking that regulates the opening of the inner frame by engaging an inner frame engaging portion provided in the inner frame locking mechanism and an inner frame engaged portion provided in the outer frame. State
When the inner frame engaging portion is disengaged (disengaged) from the inner frame engaged portion, the inner frame is unlocked to allow the inner frame to be opened.
The outer frame is
Among the frame constituent parts constituting the upper, lower, left and right sides, at least the left and right side frame constituent parts corresponding to the locking device are formed using a metal conductive material,
The inner frame engaged portion is:
It is formed using a conductive material made of metal, and electrical conduction with the left and right side frame components is achieved,
When the locking device is in the inner frame locked state, the inner frame engaging portion and the inner frame engaged portion are electrically connected to each other, and the locking device and the left and right other side frame configuration When the part is electrically connected,
4. The gaming machine according to claim 3, wherein the left and right other-side frame components function as a part of the conductive path or the predetermined ground portion.

  Even if the locking device disposed on the outer edge of the inner frame is used as a part of the conductive path and is grounded to the outside of the gaming machine via the locking device, the gaming machine will eventually be externally connected to the outside of the gaming machine. If the part that is electrically connected to the ground is, for example, a hinge member on the open / close shaft side that supports the inner frame so that it can be opened or closed, or the ground terminal of the power supply device, Since the locking device and the hinge, power supply device, etc. must be electrically connected using a ground wire etc. across the device, electromagnetic induction noise from the ground wire to various electronic devices, etc. There are concerns about the impact.

  In this respect, by using the frame constituent part of the outer frame as a part of the conductive path or a predetermined ground part as in this means, it is further away from various electronic devices arranged in the central part on the back side of the gaming machine. Since electrical continuity with the outside of the gaming machine can be achieved through the position or static electricity can be removed, the occurrence of the above-described problems can be suppressed.

  In addition, in the configuration that directly connects the ground terminal of the power supply device and the external ground outside the gaming machine using the ground wire, and the configuration that directly connects the locking device and the external ground outside the gaming machine, There is a risk of hindering the opening and closing operation of the inner frame during maintenance. In addition, problems such as disconnection of the ground wire with the opening and closing of the inner frame are likely to occur. Furthermore, in order to enable the opening and closing operation of the inner frame, it is necessary to allow a certain length of the length of the ground wire, so when closing the inner frame, the ground wire is placed between the inner frame and the outer frame. There is also a risk of damaging it. As a result, there is a possibility that appropriate static electricity removal cannot be performed.

  In this respect, according to the present means, it is possible to achieve electrical continuity with the outside of the gaming machine or to eliminate static electricity through an outer frame that is always fixed to the island facility and has no opening / closing operation. Occurrence can be suppressed.

  In addition, the inner frame with the payout mechanism etc. is very heavy, so there is a large amount of friction between the male and female hinge brackets that support the inner frame so that it can rotate. Since the force works, the opening / closing operation of the inner frame is repeated, so that the surface of the hinge fitting may be scraped or the plating may be peeled off.

  For this reason, if the surface of the hinge bracket is scraped in this way, the electrical conductivity between the male and female hinge brackets deteriorates in the configuration in which electrical conduction with the external ground outside the gaming machine is performed via the hinge member. There is a risk that it will not be possible to properly remove static electricity from the machine. Since the hinge member has a smaller capacity than the outer frame or the like, it is difficult to spontaneously discharge static electricity with the hinge member alone.

  In this regard, such a problem can be suppressed by achieving electrical continuity with the outside of the gaming machine or removing static electricity through the locking device and the outer frame as in this means.

  In addition, as a configuration in which the locking device is used as a part of the conductive path and is connected to the outside of the gaming machine via the locking device, when the administrator of the gaming machine inserts the key into the locking device, the administrator or the like Although the structure which earth | grounds to a floor surface via a human body and removes static electricity is also considered, in such a structure, there exists a possibility that the said administrator etc. may feel discomfort.

  In this respect, according to the present means, when the inner frame is locked, since it is always connected to the ground, occurrence of such a problem can be suppressed.

  Means 5. Any of means 2 to 4, wherein the resistivity of the conductive material used for forming the upstream rail member is lower than the resistivity of the conductive material used for forming the downstream rail member. The gaming machine described in 1.

  Static electricity is likely to be generated in the upstream rail member that receives the game ball derived from the tank. In other words, according to the configuration of this means, even if a discharge occurs on the guide rail, it is more likely to occur at a position closer to the tank than on the dispensing device side, so that the influence on the dispensing device can be further reduced. As a result, it is possible to efficiently remove static electricity in the upstream rail member in which the game ball is more likely to be charged with static electricity.

Means 6. The tank includes a lead-out port through which the game ball can be led downward, and a bottom portion inclined downward toward the lead-out port,
The upstream rail member is configured to receive a game ball falling from the outlet of the tank and flow down while aligning the game ball,
The specific position is
The gaming machine according to any one of means 2 to 5, wherein the gaming machine is located upstream of the position of the boundary between the bottom and the outlet in the left-right direction.

  According to the means 6, since the boundary portion between the outlet and the bottom is a position where the game ball falls on the upstream rail member, static electricity is likely to be generated. Therefore, by providing the conductive path starting from a specific part upstream from this point, static electricity hardly flows to the downstream side of the dispensing mechanism.

Mean 7 While equipped with a launcher capable of launching a game ball on the other side of the inner frame,
On the front side of the inner frame, the game balls paid out from the payout device provided near the left and right sides of the inner frame are stored and flowed down from the left and right sides to the other side while aligning the game balls. A ball tray that can be guided to the launcher;
While forming the ball tray using a resin conductive material,
The resistivity of the conductive material used for forming the ball tray is a resistivity lower than the resistivity of the conductive material used for forming the dispensing device,
A specific part on the downstream side of the specific position of the ball tray without passing through the structural part on the upstream side of the specific position of the ball tray and the structural part on the downstream side of the payout device of the payout mechanism portion The gaming machine according to any one of means 2 to 6, further comprising a conductive path for a ball tray that is electrically connected to a predetermined ground portion.

  According to the means 7, the ball tray is formed using the resin conductive material, and the resistivity of the conductive material used for forming the ball tray is lower than the resistivity of the conductive material used for forming the dispensing device. The resistivity is assumed. Therefore, in the situation where the ball tray is full of game balls and the game balls are accumulated from the payout device to the ball tray, when the static electricity charged in the game balls is discharged, the discharge is probabilistically performed on the ball tray side. It tends to occur and is less likely to occur on the dispensing device side. As a result, the game ball is paid out as if it is discharged from the payout mechanism, and the ball is easily charged with static electricity in the game ball. Can be removed, and static electricity generated in the ball tray or the like can be prevented from flowing to the dispensing mechanism side (dispensing device side). As a result, it is possible to suppress the occurrence of various problems associated with electrostatic discharge, such as prevention of malfunction of the dispensing device.

  Moreover, the ball tray and the predetermined grounding portion that are easily charged with static electricity on the game ball without going through the components upstream of the specific position of the ball tray and the components downstream of the dispensing device of the dispensing mechanism. By providing a conductive path for a ball tray that achieves electrical continuity with the ball, it is possible to suppress the static electricity removed from the ball tray from flowing upstream (the dispensing device side). As a result, the above effects can be made more reliable.

When the locking device is in the front door locked state, the front door engaging portion and the front door engaged portion are electrically connected, and the locking device and the ball tray are electrically connected. The gaming machine according to means 7, wherein conduction is achieved.

  Conventionally, the ground connection of a front door that is provided so as to be openable / closable is generally performed via the rotation shaft side of the front door. However, usually, the front door is provided with operation means (for example, a handle for operating the launching device) operated by the player, and on the back side of the front door from the operation means to the back side of the inner frame. Signal lines and the like connected to the control device are wired. Therefore, as in the configuration of the means 7, an attempt is made to provide a conductive path for a ball tray starting from the downstream side of the ball tray that is distant from the pivot axis of the front door. When connected to the inner frame side through the door's pivot shaft side, the signal line and ground wire etc. are arranged in parallel on the back side of the front door. As a result, noise may be transmitted to the control device.

  In this respect, according to the present means 8, by using the locking device as a part of a conductive path for discharging and removing static electricity charged on the game ball to the outside of the game machine or a predetermined grounding part, the front door It is not necessary to provide a conductive path in a relatively long section on the back side of the battery, and the occurrence of the above-described problems can be suppressed and the conductive path can be made relatively short.
