A motor and the like are provided. Reference numeral 5 denotes a machine frame for supporting the front frame 2 so that the front frame 2 can be opened and closed. A game board (not shown) is detachably mounted in the frame of the front frame 2. A dedicated card-type ball lending machine (not shown) is attached to one side of the pachinko machine 1. When the ball lending button is pressed with the card inserted in the card reader, the button is pressed once within the range of the card balance frequency. A predetermined number of lending balls are discharged to a supply tray or a receiving tray on the front of the pachinko machine through a ball discharging device 21 described later per turn on.

As shown in FIG. 2, the back mechanism board 3 is a synthetic resin integrally molded product having a downstream portion of a discharge gutter 8 for guiding pachinko balls from the ball storage tank 7 to a supply tray and a tray on the front side. Various unit parts are assembled on the back side. A window 9 having a shape corresponding to the mechanism on the back of the game board is opened at the center of the back mechanism board 3, and a cover (not shown) for opening and closing the window 9 from the back side is attached. 10 is a guide gutter 6 for discharging a winning ball from a collecting gutter on the back of the game board to a collection gutter behind the pachinko machine 1 via a payout unit 16.
A prize ball processing unit, 11 is a signal line that bundles a harness such as a detector 12 for detecting a shortage of balls of a pachinko ball in the ball storage tank 7, and 13 is a strength member for protecting a guide wall to a supply tray. , 14 is a cover for covering the downstream part of the discharge gutter 8, and 15 is a power distribution board.

In FIG. 1, a payout unit 16 discharges one winning ball in the guide gutter 6 each time the discharging of the winning ball is completed. A detector for detecting the presence or absence of a winning ball and a payout mechanism therein are provided. Will be taken away. Reference numeral 17 denotes a discharge control circuit for processing the discharge of a prize ball based on the detection of the presence of a ball by the winning ball detector and the discharge of a lending ball based on a command from a ball lending machine, 18 a control circuit of the hit ball launching device 4, and 19 a game situation. And a relay panel 20 for transmitting and receiving signals to and from the ball lending machine side.

The ball discharge device 21 includes a guiding gutter unit 22 for flowing down the pachinko balls from the ball storage tank 7 while rectifying the balls in two rows, a discharge unit 23 constituting an upstream portion (parallel path) of the discharge gutter, and a flow path switching. Units 24 are provided, each of which is detachably assembled at a predetermined position on the back mechanism board 3. In the assembled state, the discharge unit 23 and the flow path switching unit 24
A cover (not shown) is provided to cover these together. Reference numerals 25A and 25B denote locking holes for mounting the cover.

As shown in FIGS. 3 and 4, the ball storage tank 7 is integrally formed of a synthetic resin into a box shape, and an opening 27 is formed at the lowermost portion of the inclined bottom wall 26. The inclined bottom wall 26 is composed of a central inclined surface 26A converging from the right side of the tank to the opening 27 and an inclined surface 26B forming both wings, and a movable wall 28 swingable in the vertical direction at an intermediate position of the central inclined surface 26A. Is provided. In order to equalize the load of the pachinko ball to the entirety of the tank 7, a raised portion 29 is formed which raises a part near the opening where the depth increases and raises the bottom.

The movable wall 28 is fitted so as to close the cutout 30 opened in the inclined bottom wall 26 of the tank 7.
At the upper end side with respect to 6, a lever-shaped projection 31 is rotatably attached to a mounting piece 32 on the lower surface of the tank via a shaft 33. The lower end of the movable wall 28 is bent out of the tank 7 in an L-shape, and a small projection for restricting the movable wall 28 from entering the inside of the tank is formed on an arc-shaped curved surface centered on the axis 33 of the bent portion 34. 35 are formed. A spring 36 urges the movable wall 28 to the restricted position of the small protrusion 35, and the spring 36 is attached around the axis 33 with both ends abutting against the movable wall 28 and the lower surface of the tank 7, respectively.

Accordingly, when the inside of the tank 7 is filled with a predetermined amount or more of pachinko balls, the movable wall 28 is pushed down by the load so as to form a part of the inclined bottom wall 26. Locks on the lower surface of the tank to restrict further rotation. When the number of pachinko balls in the tank 7 decreases from this state, the movable wall 28 is gradually pushed up to the inside of the tank by the spring force, and the small projection 35 on the lower end side is locked on the lower surface of the tank 7 and further rotated. Is regulated.

In order to mount the ball storage tank 7 on the back mechanism board 3, a concave recess 37 for receiving the front side of the tank 7 is formed in the upper part of the back mechanism board 3 as shown in FIG.
Bosses 38 projecting perpendicularly from the board surface on both sides of 7
Are arranged at the top and bottom three each. On both sides of the tank 7, flanges 39 having a coupling structure 40 to the boss 38 of the back mechanism board 3 are provided.

As shown in FIGS. 6 and 7, the coupling structure 40 has substantially cylindrical engagement portions 40A and 40C for holding the upper and lower boss portions 38A and 38C, and a seat for fitting to the intermediate boss portion 38B. A clip 40a as a fixing member between the surface portion 40B and the engagement hole 38a of the upper boss portion 38A (the front locking portion expands and contracts when the knob on the rear side of the flange is pushed and pulled), and an insertion hole of the lower boss portion 38C. A screw (not shown) as an auxiliary fixing member for connecting the intermediate boss portion 38B and the seat surface portion 40B is provided.

For this reason, the tank 7 can be fixed to the back mechanism panel 3 by the connecting structures 40 on both sides while the front side is housed in the recess 37. In this case, all the engaging portions of the coupling structure 40 and the like are fitted to the corresponding boss portions 38 in a direction perpendicular to the board surface, so that the load of the pachinko balls stored in the tank 7 can be sufficiently supported. Further, since the tank 7 can be attached to and detached from the board of the back mechanism board 3 in a direction perpendicular to the board, there is no need to waste space on the board for these operations. Since the load in the tank 7 does not act in the direction of removing the tank 7, if the engaging force of the clip 40a is sufficient to prevent the detachment, the screw as the auxiliary fixing member need not be used.

The ball shortage detector 12 of the ball storage tank 7 is turned on and off by opening and closing the contacts, and the operator 41 of the contacts is arranged on the side of the back mechanism board 3 with the movable wall 28 of the tank 7 facing the movable wall 28 side. In this case, the detector 12 has two control systems, a lamp for displaying a shortage of balls in the tank (for example, provided on an upper portion of a front frame of a pachinko machine) and an operation mechanism for replenishing the tank with pachinko balls. They are mounted side by side in a storage section 42 formed below the recess 37 of the back mechanism board 3 (see FIG. 5).

These detectors 12 are turned off when the amount of stored pachinko balls in the tank is equal to or more than a predetermined value and the movable wall 28 is pushed down to the restricted position of the lever projection 31, and the pachinko balls are stored. When the amount decreases and the movable wall 28 is pushed up by the spring 36, it turns on.

By the way, regarding the positional relationship between the detector 12 and the movable wall 28, when the operator 41 of the detector 12 can directly contact the lower surface of the movable wall 28, the movable wall 28 may be attached when the tank 7 is mounted. May touch and damage the actuator 41, and the detector 12 is mounted on the back mechanism panel 3 as shown in FIGS.
Of the movable wall 28 just below the recess 37 of the tank 7,
Is set so that it does not overlap with

In this case, the accommodating portion 42 of the detector 12 is formed so as to be recessed from the board surface to substantially the same depth as the concave portion 37 of the tank 7, and the lower surface of the movable wall 28 is provided with the detector 12 in the set state of the tank 7. A pressing piece 43 extending so as to be suspended from the actuator 41 is provided. The distal end of the pressing piece 43 is formed in an upwardly inclined portion 44, thereby preventing an excessive force from acting on the actuator 41 of the detector 12 when the tank 7 is mounted.

In FIGS. 3 and 4, reference numeral 45 denotes an additional member fitted to a side wall for preventing the pachinko balls from spilling backward from the tank 7 when the front frame 2 is opened and closed. It is formed like a fence. Also,
Numeral 46 designates a ball drop hanging in the parallel path of the guide gutter unit 22 and is rotatably supported by a mounting piece 32 on the lower surface of the tank 7 via a shaft 47.

1 (flow path conversion section), and a flow dividing wall 53 that defines a parallel path 52 is provided in the gutter of the upstream section 50. The flow dividing wall 53 is formed so that its height gradually increases toward the downstream of the gutter (finally rises to a height equal to or larger than the diameter of the pachinko ball).

The downstream section 51 is formed by assembling first and second case-shaped flow path forming members 54 and 55 with a substrate 56 interposed therebetween. A vertical meandering path 58 connected via the U-turn path 57 is formed. FIG. 1 shows the inside of the downstream portion 51.
2, a movable piece 59 that can freely swing up and down by a shaft 58 installed on a gutter immediately before each U-turn path 57 as shown in FIG.
And a detector 60 for detecting the broken state of the pachinko ball in the gutter based on the swing of the movable piece 59. FIG. 12 shows one gutter in the downstream portion 51, and FIG. 13 shows the other gutter.

As the detector 60, a gate type optical sensor which allows the movable piece 57 to enter is used. When the movable piece 59 is pushed up into the gate type sensor 60 due to the continuation of the pachinko ball, it is turned off, and the pachinko ball is turned off. Is turned on when the movable piece 59 descends into the gutter after the flow of the flow is interrupted. The detector 60 has a common wiring plate 61 (connector 6
2 are provided side by side, and a mounting hole 63 and a lid piece 64 are provided on one side of the component member 55 in order to incorporate this into a predetermined position in the downstream portion (see FIG. 11).
The position where the movable piece 59 is attached is, but when the detector 60 is turned on by the lowering of the movable piece 59, it is disposed on the downstream side (in two gutters) of the movable piece 59 as a discharge standby ball for one lending ball. It is set so that more pachinko balls remain than the number of ejected pachinko balls.
Reference numeral 65 denotes a guide plate for suppressing the pachinko balls from overlapping from the upstream portion 50, which is supported so as to be vertically swingable via a shaft 66 near the entrance of the downstream portion 51, and somewhat overlaps the parallel path 52. A weight 67 is provided on the tip side extending
Is provided.

The meandering path 58 is adjacent to the front and rear with the substrate 56 interposed therebetween, and is formed so as to be connected to a lower end portion which is opened in a state of being bent right and left offset from each other. At the lower end of each meandering path 58, a shutter 68 for preventing falling of the ball is provided. The shutter 68 is shown in FIGS.
As shown in FIG. 5, one flat plate is formed in a stepped shape corresponding to the positional relationship between the two meandering paths 58 on the plane, and is freely slidable (open / close) in the front-rear direction in the lower end opening. A spring 69 urges the shutter 68 to the closed position. When the shutter 68 is connected to the discharge unit 23 described later, the spring 6 is
9 is located between the meandering paths 58 so that the shutter 68 can be pushed to the open position against the urging force of the slit 9.
0 is provided. The shutter 68 is assembled together with the spring 69 from a mounting hole formed in the component member 54 on one side. The spring 69 has a pin 73 between the lid member 71 of the hole and the spring receiver 72 of the shutter 68 at the center thereof.
a and 73b (see FIG. 11).

The shutter 68 is connected to the discharge unit 23.
When there is a continuous pachinko ball in the meandering path 58 at the time of separation from the pachinko ball, the closing operation is performed so as to push it apart. Such an inclined surface is formed. A semicircular notch 7 is formed at the lower end of each of the meandering paths 58 so that a pachinko ball located below the shutter 68 and between the discharge unit 23 and the discharge unit 23 does not become an obstacle when the discharge unit 23 is separated.
4 are formed.

In order to attach the guide gutter unit 22 to the back mechanism panel 3, a rib 75 for supporting the load horizontally along the gutter is provided in the center of the lower surface of the upstream portion 50 as shown in FIGS. Then, a clip 76a and a screw mounting hole 77a are provided on the rib 75. Further, on the upstream side of the parallel path 52, a flange 78 abutting on the board surface is provided on one gutter wall side facing the back mechanism board 3, and on the downstream side, the other gutter wall is provided with the weight of the pachinko ball in the depth direction of the gutter. Flanges 79 for supporting the acting bending moment are respectively formed. A clip 76b and a screw mounting hole 77b are provided on the flange 78, and a clip 76c is provided on the flange 79. 76d is a clip of the unit downstream part 51, 7
7d is a screw mounting hole.

A horizontal support wall 80 on which the rib 75 is placed is provided on the back mechanism panel 3 at a position where the guide gutter unit 22 is mounted. Further, bosses 81 and 82 are provided on the surfaces facing the ribs 75 and the flanges 79 and the like.
At 82, engagement holes 81a, 81c, 81d for the clips 76a, 76c, 76d or screw holes 82a, 82c, 82d for the screws are respectively formed. In addition, on the board surface, an engagement hole 81b with the clip 76b and a screw hole 82b are provided on a contact surface with the flange 78.

The guiding gutter unit 22 is connected to the back mechanism panel 3.
The rib 75 and the flange 78,
Attachment is made by connecting the clips 76a to 76d or screws with screws 79 or the like. In this case, the rib 75 on the support wall 80 moves the rib 75 from the upstream side to the downstream side at the center of the gutter against the load in the gutter. Since the unit upstream section 50 is held at a predetermined inclination angle, that is, the change in the inclination angle with time can be almost completely prevented, and the inclination of the gutter in the depth direction can be effectively prevented. Also, the flange 78 on one gutter wall side and the flange 7 on the other gutter wall facing the back mechanism panel 3 on the upstream side and the downstream side of the parallel path 52 are provided.
At 9, the clip 76b, 76c or the like is used to support the back and forth in the depth direction, so that a better support rigidity can be obtained against the bending moment due to the weight of the pachinko ball. Note that the clips 76a to 76d have the same configuration as the clip 40a of the ball storage tank 7, and if the engaging force of the clips 76a to 76d is sufficient to prevent the clips 76a to 76d from coming off, the screws as auxiliary fixing means need not be used. .

In FIG. 11, a conductive metal plate 90 which also serves to reinforce the road surface is attached to the parallel path 52 of the unit upstream section 50 from the position facing the opening 27 of the ball storage tank 7 to the downstream side. The metal plate 90 is for grounding the static electricity and the like of the pachinko ball, and is formed in a belt shape having substantially the same width as the road surface. Is done. Then, as shown in FIG. 19, the metal plate 90 is provided with slits 9 on both sides of the road surface.
3 and the bent piece 9 on the underside of the gutter.
It is fixed by bending 1 inside.
In this case, since the rib 75 hinders the bending, in this example, a small opening 94 is provided at the base of the rib 75, and a tool is inserted from the opposite side using the opening 94 so that the bending can be easily performed. It has become. 20 and 21, the slit 93 may be formed in an inclined state to promote inward bending when the bent piece 91 is inserted, or the inclined projection 95 may be formed on both sides of the rib 75. As a result, the distal end side of the bent piece 91 is separated from the rib 75, so that subsequent bending can be easily performed. The connection terminals 92 of the two metal plates 90 are inserted into slits on the side of the ribs 75, respectively, and are connected to the connection posts 97 erected on the board surface facing the notches 96 of the ribs 75 in the state where the guide gutter unit 22 is mounted. They are superposed and joined (see FIG. 17).

As shown in FIGS. 22 to 25, the discharge unit 23 includes first and second flow path forming members 100 and 101 in a case shape.
In addition, an adjustment path 103 connected to the meandering path 58 on the guide gutter unit 22 side is formed inside the cover member 102 by overlapping the cover member 102. The adjustment path 103 mainly includes an upstream vertical portion 104 and a downstream inclined portion 105, and a discharge mechanism 106 that regulates the flow of the pachinko ball near the lower end of the inclined portion 105 and detects the discharged ball immediately upstream thereof. A detector 107 is provided.

Here, the adjustment path 103 is connected to the back mechanism board 3 from the introduction section 109 corresponding to the positional relationship of the lower end of the meandering path 58 on the plane to the lead-out section 110 which is opened at the same position in the front-rear direction. The flow path is formed to bend back and forth while being adjacent to the left and right in the mounting direction.

The discharge mechanism 106 is composed of a pair of locking members 111 which can be respectively advanced and retracted into the inclined portion 105, and a solenoid 112 which respectively advances and retracts them. The locking member 111 is formed in a hook shape at the tip end side, and is swingably supported by a shaft 113 via a base portion of the side of the inclined portion 105. The tip of the locking member 111 is formed on an arc-shaped sphere blocking surface coinciding with the swing locus, and a link 1 is provided near the base (at a position offset with respect to the shaft 113).
The solenoid 112 is pin-connected via. 19
Reference numeral 9 denotes a stopper that regulates the retracted position of the locking member.

On the gutter wall of the inclined portion 105, a slit 115 corresponding to the tip side of the locking member 111 is formed. In addition,
The positional relationship between the locking member 111 and the slit 115 with respect to the inclined portion 105 is as follows.
The two pachinko balls are set so as to be lined up in the inclined portion 105 in the approaching state where it hits the end of No. 15.

When the solenoid 112 is not energized, the locking member 111 enters into the inclined portion 105 and regulates the downflow of the pachinko ball by the ball blocking surface. When the solenoid 112 is energized from this state, the locking member 111 retreats from the inside of the inclined portion 105 via the link 114, and allows the pachinko ball to flow down. Then, when the power supply to the solenoid 112 is cut off, the locking member 111 returns to the initial state by the urging force of the return spring 116, enters the inclined portion 105, and regulates the flow of the pachinko ball again (FIG. 2).
4, FIG. 25).

In this case, in order to prevent the locking member 111 from bouncing off at the end of the slit 115 when returning to the initial state, the link member 20 is arranged below the locking member 111 so as to follow the same.
0 is rotatably supported at its intermediate portion via a shaft 201. A locking pin 202 for the locking member 111 is formed on the distal end side of the link member 200, and a rubber bush 203 for absorbing shock is fitted around the pin 202. At the rear end of the link member 200, a weight 204 for urging the locking member 111 in the rotation direction opposite to the stroke when returning to the initial position is added.

Therefore, the link member 200 swings with the movement of the locking member 111 while sliding the outer periphery of the locking pin 202 against the lower surface of the locking member 111, and the locking member 111 is moved to the initial position. When returning, the urging force of the weight 204 acts as a resistance, and the operating energy of the locking member 111 is absorbed by the sliding friction on the rubber bush 203. Therefore, the momentum of the locking member 111 is appropriately directed toward the end of the slit 115. Can be attenuated.

The weight 204 of the link member 200
As a result, the locking member 111 is urged backward from the entry position with respect to the inclined portion 105, so that the solenoid 112
Is also obtained. Since the locking member 111 is in line contact with the rubber bush 203, it hardly sticks to the rubber bush 203. 205 is the locking member 111
This is a stopper that regulates the swing angle of the link member 200 (the position at which the link member 200 comes into contact with or separates from the locking member 111) so that the damping force can be effectively applied within a necessary range in view of the responsiveness of the link member 200. Is formed.

When the discharge unit 23 is detached from the back mechanism panel 3 during maintenance or inspection, the locking member 111 is connected to the link member 200, depending on the position of the stopper 205.
Is manually operated to the retreat side, so that the pachinko ball inside the unit 23 can be easily extracted.

The discharge ball detector 107 is a gate type that allows the pachinko balls to pass one by one, and is inclined at a position substantially surrounding the center of the second pachinko ball following the head when the locking member 111 enters. It is installed in the unit 105 and outputs an on-off signal in accordance with the discharge of the pachinko ball. In addition, since the detector 107 has both sides of the gate type slightly protruding inside the gutter wall in the inclined portion 105, the adjustment path 10 is used to ensure the smooth passage of the pachinko ball to the detector 107.
A guide projection 120 is formed on the both side gutter walls along the center of the flow path and continues at the same height as the projection of the detector 107.

By the way, the adjusting path 103 is adapted to keep the speed and interval of the pachinko balls flowing down by the vertical portion 104 on the upstream side and the inclined portion 105 on the downstream side, etc., and particularly from the vertical portion 104 to the inclined portion 105. By hitting the pachinko ball from the bottom wall 122 of the vertical portion 104 to the inclined wall 123 at a predetermined angle at the bent portion 121, the ball is dropped on the inclined portion 105 at a constant speed and at an interval. The bottom wall 122 of the vertical portion 104 is provided with a replaceable component having excellent wear resistance and cushioning properties because the flowing pressure of the pachinko ball acts greatly.

Reference numeral 130 denotes a switchboard for the solenoid 112 and the detector 107, which includes a connector 131 for the discharge control circuit 17 and a connector 132 for the flow path switching unit 24, which will be described later. The switchboard 130 is set in the storage section 134 on the rear side of the unit 23, and the cover member 13 of the storage section 134 is attached to the constituent member 100 on one side.
5 are provided.

In order to attach the discharge unit 23 to the back mechanism board 3, a fitting recess 135 is provided on the right side of the window 9 of the back mechanism board 3 as shown in FIG. The fitting recess 135 is also formed integrally with a mounting space for the flow path switching unit 24. A flange piece 136 for positioning the two units 23 and 24 up and down is provided on an edge of the recess 135, and on one side of the recess 135. Is a locking portion 137 that supports the lower portion of the discharge unit 23
And the retaining portion 13 for locking the lower part of the flow path switching unit 24
8 are provided. Further, a side wall 140 with a claw 139 for locking the rear surface of the unit 23 set in the concave portion 135 is provided upright on the panel surface on the side of the mounting position of the discharge unit 23.

However, on condition that the ball-out detector 60 is turned off, the prize ball is discharged when the detector in the winning ball payout unit 16 detects the presence of a ball, and the lending ball is discharged in response to a discharge request from a ball lending machine. When the prize ball is discharged, the solenoid 112 of the discharge mechanism 106 is driven, and the number of discharges is counted based on a signal from the detector 107. When the number reaches a predetermined prize ball number, the drive of the solenoid 112 is performed. Stop. Also,
The payout mechanism is controlled so as to discharge one winning ball based on a signal from a detector in the payout unit 16 at the end of discharging the prize ball.

When the lending ball is discharged, the driving of the solenoid 112 of the discharging mechanism 106 is controlled in accordance with the requested number, and at the end of the discharging, a discharging end signal for instructing the ball lending machine to perform a process of subtracting the card balance frequency is output. You do it.

The discharge control circuit 17 is provided with a discharge mechanism 106.
The control of alternate discharge from only one locking member and simultaneous discharge from both locking members is selectively performed according to the number of discharge requests to the solenoid 112.

The flow path switching unit 24 is constructed by arranging side-by-side members 150 and 151 and substrates 152 and 153 side by side as shown in FIGS. Between 153, two branch channels 154 connected to the adjustment path 103 of each discharge unit 23 are formed. Note that one branch channel 154 is formed by a gutter wall integrally formed on the surface of the side member 151 facing the substrate 153, and the other branch channel 154 is formed by the substrate 15.
The gutter wall is integrally formed on the surface facing the second side member 150.

Each branch 154 includes a vertical portion 155 on the upstream side, a meandering portion 156 on the downstream side, and a branch portion 157. An opening / closing door 158 is provided at the entrance of the branch portion 157.
Each opening / closing door 158 has two substrates 152 and 153 at the lower end base.
Are rotatably supported on both sides of a shaft 159 that penetrates through them, and are connected to each other by rods 161 that also pass through guide holes 160 of the substrates 152 and 153. A lever member 162 is rotatably mounted at the center of the shaft 159 at the central portion of the U-shape, and one end of the lever member 162 is opened and closed via a long hole 163.
The other end is engaged with a solenoid 164 for switching a flow path by a pin via a link 165 at the other end.

That is, the opening and closing doors 158 on both sides are integrally driven by one solenoid 164, and in the closed state (when the solenoid 164 is not energized), the branching portion 157 is shut off as shown in FIG. At the time of opening (when the solenoid 164 is energized), the branch portion 157 is connected to the vertical portion 155 and the meandering portion 156 is shut off as shown in FIG. Note that concave sheet portions 166 that lock the door 158 between the closed position and the open position are formed on the gutter walls on both sides of the vertical portion 155. Reference numeral 167 denotes a return spring of the solenoid 164.

The flow path switching unit 24 is formed on the front side with a stepped engagement portion 168 with the fitting recess 135 of the back mechanism board 3, and like the discharge unit 23, is provided with a stepped engagement from behind the back mechanism board 3. The meandering portion 156 is connected to the discharge gutter 8 on the side of the back mechanism board 3 in this state by setting the portion 168 in the fitting recess 135 and locking it with the retaining portion 138 (see FIG. 26). ). A connection recess 169 for receiving the stepped engagement portion 142 below the discharge unit 23 is formed between the left and right side members 150 and 151 in the upper portion of the flow path switching unit 24.

The inside of the engaging portion 168 is provided between the side members 150 and 151 and the substrates 152 and 153, respectively.
A groove 170 having a U-shaped cross section extending downward from the groove 7 is provided, and a connecting portion 157 in the fitting recess 135 is connected to a ball drain gutter (not shown) integrally formed on the front side of the back mechanism board 3. A road is formed. The fitting recess 1
At the lower end of 35, a hole (not shown) is provided for opening a communication path to a gutter.

Since the bottom wall 171 of the vertical portion 155 hits the pachinko ball falling from the discharge unit 23 side vigorously, the bottom wall 171 is replaceably mounted using a separate component having excellent wear resistance and cushioning properties. This component part 171 is composed of a delta-shaped part 172 forming the guide wall of the meandering part 156 and a block-shaped part 173 forming the lower wall of the entrance of the branch part 157. Part 172 and block-shaped part 1
The fixing members 73 are fixed between the substrates 152 and 153 and the side members 150 and 151 via the engaging projections 174A and 174B fitted to the base member 73. The component part 171 has an arc-shaped concave portion 175 surrounding the base of the door 158 on the upper surface of the block-shaped portion 173 and a delta-shaped portion 172 due to the positional relationship with the opening / closing door 158.
Notch 177 for attaching gate 176 for preventing intrusion of foreign matter such as wire (described later) between
Is formed. Reference numeral 178 denotes a cushioning void formed in the block-shaped portion 173.

The meandering portion 156 moderately attenuates the flow speed of the pachinko balls, and attempts to open the discharge mechanism 106 of the discharge unit 23 by allowing wire or the like to enter from a supply tray or a tray on the front side of the pachinko machine 1. It also has a function of preventing fraud, but in this case, in order to further completely prevent fraud, a foreign matter intrusion prevention gate 176 that blocks a bent portion on the downstream side of the meandering portion 156 from above is provided. The prevention gate 176 is rotatably supported at one end located within the notch 177 of the component part 171 via a shaft 179, and moves from the closed position where it hangs down by its own weight to the notch 177.
The gutter is opened only in the range of the rotation in the downstream direction, that is, only in the downflow direction of the pachinko balls. The rotation of the prevention gate 176 from the closed position to the upstream side is regulated by the inner surface of the notch 177 and the locking step 180 of the gutter wall.

A groove 181 that is deeply tangentially recessed in the upper part of the curved outer wall is formed in the bent portion on the upstream side of the meandering portion 156. And stop the invasion to the upstream side.

Since the discharge unit 23 and the flow path switching unit 24 incorporate the solenoids 111, 112 and 164, respectively, the heat radiation holes 19
0 is formed (see FIGS. 22 and 28). Further, the channel switching unit 24 is provided with a cleaning hole 191 for removing dust accumulated in the meandering portion 156 during maintenance and inspection.

By the way, the branch channel 154 of the channel switching unit 24 is branched in the front-rear direction with respect to the back mechanism board 3 and has a groove 170 which forms a communication path leading to a ball drain gutter of the back mechanism board 3.
Is formed so as to overlap with the meandering path 156, the space in the depth direction can be effectively used, and the solenoid 164 for driving the opening / closing door 158 of the branch portion 157 can also be disposed at the front and rear positions of the flow path. 156 to back mechanism panel 3
Since the flow path is formed so as to bend back and forth while being adjacent to the left and right, the installation space on the board surface can be significantly reduced as in the case of the discharge unit 23.

As shown in FIG. 32, the discharge gutter on the back mechanism panel 3 side is formed in a merging passage 182 that opens in the meandering portions 156 arranged on the right and left downstream of the flow passage switching unit 24, and a pachinko machine is provided upstream of the merging passage 182. Outlet 183 leading to the supply tray on the front
Is provided. The downstream side of the junction channel 182 is also connected to a tray via a gentle slope 184.

The strength member 1 is provided on the guide wall to the outlet 183.
3, a dish-shaped introduction portion 185 for receiving a pachinko ball is provided, and a ball receiver 187 extending diagonally above the introduction portion 185 and directly below the opening 186 with the meandering portion 156 is formed integrally with the gutter wall.

Therefore, the pachinko balls from the flow path switching unit 24 fall into the introduction part 185 along the ball receiver 187 and are first discharged from the outlet 183 to the supply tray, and the supply tray is filled with the pachinko balls. At this time, it falls from the introduction portion 185 and is discharged to the tray via the inclined portion 184.

The back mechanism board 3 is formed with a ball drain gutter connected to the lower end of the fitting recess 135 using the recess space on the front side, and the pachinko ball from the branch portion 157 of the flow path switching unit 24 is used for the game board. As well as the winning ball from the payout unit 16 and the winning ball from the payout unit 16.

In the discharge operation of the entire back mechanism of the pachinko machine 1, the pachinko balls from the ball storage tank 7 are guided from the guiding gutter unit 22 to the discharge unit 23, and enter the gutter in a normal state. The downflow is regulated by 111.

When a game ball wins in the winning opening of the game board, all the winning balls enter the collecting gutter on the back side of the game board and are guided to the payout unit 16 thereunder, and the flow is once stopped. When the winning ball detector detects the presence of a ball and requests the discharge of a winning ball, the solenoid 112 of the discharging unit 23
Is driven to convert the locking member 111 to an open state for a predetermined operation time.

As a result, the pachinko balls are discharged from the discharging unit 2
3 is discharged to the supply tray or the receiving tray on the front of the pachinko machine 1 through the meandering part 156 of the flow path switching unit 24 and the downstream part of the discharge gutter 8.
When the count value of the pachinko balls detected at the time reaches the required number, the stop of the solenoid 112 causes the locking member 111 to stop.
Is returned to the closed state.

In this case, the locking member 111 is
Since the stroke speed is moderately attenuated by the swing of 00, the bouncing does not largely bounce at the end of the slit 115, and the speed and interval of the pachinko balls flowing down the adjusting passage 103 are properly maintained. There is also little chance of entering the gutter and biting the pachinko balls.

When the discharge of the prize ball is completed, one payout ball is discharged by the operation of the payout mechanism. When the detector detects the presence of the ball by the next prize ball, a request to discharge the prize ball is generated again. Will do.

When a request to discharge a loaned ball based on the ball lending machine occurs, the solenoid 112 of the discharge unit 23 is controlled in the same manner as described above according to the number of requests, and the locking member 11
Let lend out the lending ball through 1. By pressing the ball lending button on the front of the pachinko machine 1, the lending ball can be repeatedly discharged within the range of the balance frequency of the card.

The number of pachinko balls in the ball storage tank 7 gradually decreases as the prize balls and rental balls are discharged.
When the ball shortage detector 12 is turned on by the swing of the movable wall 28, a certain amount of pachinko balls are supplied into the tank 7.
