In the following description, for convenience of explanation, the front and rear, right and left and up and down directions are defined as directions in the state of being attached to the pachinko machine PM with reference to the state of FIG. The directions will be referred to as front and rear, left and right, and up and down, respectively.

  The firing unit 100 is detachably attached to the game assisting board 25 using four fixing screws 101 (see FIG. 15) in an arrangement posture adjacent to the speaker 26 on the front side of the front frame 2. The launch unit 100 is mainly configured by a unit case 110, a ball feeding mechanism 140, a launch mechanism 150, and a launch control board 160.

  The unit case 110 is provided on the front side of the game assisting board 25 and serves as a mounting base for the launching mechanism 150. The unit case 110 is attached to the front side of the case main body member 120 so as to A case lid member 130 serving as a mounting base is provided. The unit case 110 is formed with a substantially rectangular launch port 111 for allowing a game ball launched by the operation of the launch mechanism 150 to pass therethrough.

  The case body member 120 is made of a resin material such as polycarbonate (PC) or polyacetal resin (POM), and is formed into a rectangular plate shape by molding means such as injection molding. A main body side insertion hole 121 is formed through the front and rear.

  The case lid member 130 has a horizontally long case base wall 131a and left and right and upper and lower side walls 131b surrounding the case base wall 131 and extending rearward, and is injected using a transparent resin material such as ABS resin. By a molding means such as molding, it is formed into a box shape with an open rear surface with the side surface facing the case main body member 120 being opened as a whole. On the left and right and upper and lower corners of the case base wall 131a, stepped hole-like lid-side insertion holes 132 are formed through the front and rear. The left and right side walls 131b of the case lid member 130 are formed with locking pieces 131c. The locking pieces 131c are locked to the side surfaces of the case main body member 120, so that the case lid member 130 becomes the case main body member. 120 is integrally coupled to the lid.

  The case lid member 130 is formed with a first storage chamber 133 a for storing the ball feeding mechanism 140 and a second storage chamber 133 b for storing the firing control board 160. In addition, a case opening 134 for exposing the four board-side connectors 163C to 166C mounted on the launch control board 160 to the outside of the case is formed in the case lid member 130 so as to penetrate the case base wall 131a. ing. The case opening 134 is opened at a position corresponding to the mounting position of the board side connectors 163C to 166C.

  The case lid member 130 is formed with a ball inlet 135 that communicates with the ball feeding duct 35 of the upper ball tray 30 and receives a game ball delivered from the ball feeding duct 35. A ball supply passage 136 is formed that extends into the interior of the player and allows the game ball to flow down from the upper ball tray 30 to the launching mechanism 150. The ball supply passage 136 is connected to the ball inlet 135 and extends backward, and a ball lead-out passage 138 that sends the game ball connected to the ball introduction passage 137 and reaching the end of the ball introduction passage 137 to the launching mechanism 150. And is formed from.

  The ball introduction path 137 extends rearward from the ball inlet 135 (case body member 120 side) and is closed at the rear end thereof, and a bottom surface 137a extending front and rear is inclined downward toward the left ball lead-out path 138. Yes. Therefore, the game ball introduced into the ball introduction path 137 from the ball inlet 135 flows down toward the ball lead-out path 138. On the other hand, a ball outlet 139 is formed at the end of the ball outlet path 138, and a game ball that has reached the ball outlet path 138 passes through the ball outlet 139 and flows down to the launching mechanism 150.

  The ball feed mechanism 140 is swingably provided with a ball feed valve 141 that receives the game balls arranged in the ball supply passage 136 one by one in accordance with the arrangement order and feeds them to the firing mechanism 150. Above the valve 141, a ball feed solenoid 145 as a drive source for swinging the ball feed valve 141 is disposed.

  The ball feed valve 141 is opposed to the ball introduction path 137 and is recessed in a concave shape so as to receive the game balls waiting on the ball introduction path 137 one by one, and a ball that forms the bottom surface of the ball reception depression 142. A guide piece 143 and a ball stop piece 144 for damming a game ball waiting in the ball introduction path 137 are provided. The bottom surface 141a of the ball receiving recess 142 (the upper surface of the ball guide piece 143) is formed so as to be inclined downward toward the launching mechanism 150 disposed rearward. The ball feed valve 141 is centered on the swing pin 141c supported by the unit case 110, and the ball stopper piece 144 opens the ball introduction path 137 and the ball guide piece 143 closes the ball outlet 139 ( 10 and FIG. 11) and a ball outlet opening position (see FIG. 12 and FIG. 13) in which the ball stopper piece 144 closes the ball introduction path 137 and the ball guide piece 143 opens the ball outlet 139. It is configured to be able to swing between.

Thus, the ball feed valve 141 is configured to swing up and down (around the inside of the paper surface of FIG. 10) about the swing pin 141c, and current is supplied to the ball feed solenoid 145 to magnetize it. Sometimes, the iron plate part 146 provided at the upper end of the ball feed valve 141 by the suction force
Is sucked and swings to the upper ball outlet closing position. On the other hand, when the ball feed solenoid 145 is in a non-energized state, the ball feed valve 141 is lowered by the action of gravity, and the ball receiving recess 142 swings and displaces to a ball outlet open position that matches the ball outlet 139. When the ball feed valve 141 is displaced to the ball outlet open position, the game ball received in the ball receiving recess 142 passes through the ball outlet 139 and flows down to the ball hitting position in the launch mechanism 150. That is, the ball receiving recess 142 forms a ball lead-out path 138 of the ball supply passage 136.

  The ball feed operation of the ball feed mechanism 140, that is, the ON / OFF control of the ball feed solenoid 145 for swinging the ball feed valve 141, is performed by a firing control board 160 that causes a hammer 151 of the firing mechanism 150 to be described later to swing. The operation is controlled in synchronization with the operation of the solenoid 154, and each time a game ball is fired from the launch mechanism 150 based on the turning operation of the launch handle 8, the game balls are sent one by one to the hitting position in the launch mechanism 150. It has become.

  The firing mechanism 150 is located on the front surface side of the case main body member 120 and provided with a hammer 151 swingable in a plane substantially parallel to the board surface of the game board 10, and a hammer provided on the rear surface side of the case main body member 120. A launch solenoid 154 that swings 151 and a launch rail portion 156 that guides the launched game ball to the guide rail 11 are provided. The firing solenoid 154 is a rotary solenoid, for example, and is attached to the rear surface side of the case body member 120 by being screwed and fixed using a plurality of screws 154b. The drive shaft 154a of the firing solenoid 154 protrudes to the front side of the case body member 120 through a drive shaft insertion hole (not shown) formed through the front and back of the case body member 120, and this drive shaft 154a. Is inserted into a shaft hole (not shown) of the hammer 151 and the screw portion at the tip of the drive shaft 154a is screwed with a fixing nut 155 so that the hammer 151 is integrally connected to the drive shaft 154a. It has become. In this way, the hammer 151 is attached to the front surface side of the case body member 120, and the firing solenoid 154 is driven based on the command signal from the firing control board 160, whereby the drive shaft 154a is driven on the front surface side of the case body member 120. Oscillating up and down around the center.

  The hammer 151 has a hammer arm 151a made of a metal thin plate, and a synthetic resin covering portion 151b formed by covering the left peripheral portion of the hammer arm 151a by insert molding, for example. A hammer head 151c for hitting a game ball is formed on the part. In the vicinity of the hammer head 151c, an empty portion 151d is formed for increasing the resilience of the hammer head 151c (synthetic resin) and launching a game ball with high resilience. A step 151e is formed above the hammer head 151c to prevent the hammer 151 from swinging upward.

  Further, on the front side of the case body member 120 adjacent to the hammer 151, a lower stopper 152 that elastically receives the covering portion 151b at a swing position retracted downward from the hitting position of the hammer head 151c, a hammer head An upper stopper 153 is provided for elastically receiving the covering portion 151b at a swing position slightly exceeding the hitting position of 151c. Therefore, the hammer 151 is centered on the drive shaft 154a of the firing solenoid 154, and the lower limit position where the covering portion 151b abuts on the lower stopper 152 and the downward swing is restricted (this is referred to as a “fire standby position”). ) And an upper limit position (this is referred to as a “firing completion position”) in which the covering portion 151b is in contact with the upper stopper 153 and the upward swing is restricted. The lower stopper 152 is formed of a base portion 152a and a cushion body 152b, and the upper stopper 153 is formed of a base portion 153a and a cushion body 153b. Here, since the step 151e contacts the lower end of the guide holder 157, which will be described later, after the hammer 151 contacts the upper stopper 153, an excessive impact acts on the cushion body 153b of the upper stopper 153. Can be prevented.

  The firing rail portion 156 is provided on the front surface side of the case main body member 120 and temporarily holds the game ball supplied from the ball feeding mechanism 140 according to the hitting position of the hammer head 151c, the case main body member 120, A firing rail 158 having a V-shaped side sectional view screwed to an integrally formed mounting base 122, and a guide for preventing a foul ball provided near the firing rail 158 from colliding with the firing rail 158. Member 159. The firing rail 158 is screwed to a base 122 formed integrally with the case main body member 120 and extends obliquely upward to the right from the holding position of the game ball by the guide holder 157. On the extension line, the unit case A launch port 111 opened at 110 is located.

  The launch control board 160 is a board mainly for controlling the launch of a game ball (e.g. launch intensity and launch timing), and a rectangular printed wiring board 161 is used as a board, and a control module 162 is added to the printed wiring board 161. And electrical / electronic components such as connectors 163C to 166C are mounted to form a launch control circuit. As shown in FIG. 14, the launch control board 160 includes a payout control board 47, a launch handle 8 (a launch volume 8a and a touch sensor 8b incorporated therein), a ball feed solenoid 145, a launch solenoid 154, and the like. Through 176 (see FIG. 15). Here, the firing volume 8a is composed of an angle detector such as a potentiometer, for example, and detects a rotation operation amount of the firing handle 8. Further, the touch sensor 8b detects whether or not the player is in contact with the firing handle 8.

  The first board side connector 163 </ b> C (input terminal) is a connector for electrical connection with the payout control board 47, and the harness side connector 173 </ b> C formed at the end of the harness 173 electrically connected to the payout control board 47. The launch control board 160 can communicate with the payout control board 47 in both directions or in one direction.

  The second board-side connector 164C (input terminal) is a connector for electrical connection with the firing volume 8a of the firing handle 8, the touch sensor 8b, and the like, and is connected to the end of the harness 174 that is electrically connected to the firing handle 8. The harness-side connector 174C thus formed is connected to be detachable. The firing control board 160 determines whether or not the player is in contact with the firing handle 8 based on the detection signal from the touch sensor 8b, and rotates the firing handle 8 based on the detection signal from the firing volume 8a. The amount is detected, and the driving of the ball feed solenoid 145 and the firing solenoid 154 is synchronously controlled according to these detection signals.

  The third board side connector 165C (output terminal) is a connector for electrical connection with the ball feed solenoid 145, and the harness side connector 175C formed at the end of the harness 175 electrically connected to the ball feed solenoid 145. The firing control board 160 outputs a drive signal to the ball feed solenoid 145 at a constant cycle.

  The fourth board side connector 166C (output terminal) is a connector for electrical connection with the firing solenoid 154, and is fitted with the harness side connector 176C formed at the end of the harness 176 electrically connected to the firing solenoid 154. The firing control board 160 outputs a drive signal to the firing solenoid 154 in synchronization with the drive of the ball feed solenoid 145.

The board-side connectors 163C to 166C and the harness-side connectors 173C to 176C form a male-female connector, and the fitting and unplugging directions of these connectors are left and right along the plane of the board. (That is, the arrangement direction of the connection pins in both connectors is set in the direction orthogonal to the board).

  In the launch unit 100 configured as described above, when the player is not operating the launch handle 8, the output signal of the touch sensor 8b is in a non-contact state in which the player's contact is not detected. The launch control board 160 determines that the player is in a standby state in which no game is played, and turns off the operation of the ball feed mechanism 140 and the launch mechanism 150. That is, since the firing solenoid 154 of the firing mechanism 150 is in a non-energized state according to a command from the firing control board 160, the hammer 151 is lowered by its own weight and stopped at the firing standby position.

  On the other hand, when the player grips and rotates the launch handle 8, the output signal of the touch sensor 8b is in a contact state in which the player's contact is detected, and the game ball stored in the upper ball tray 30 is moved to the ball feed mechanism 140. The ball is detained one by one at the hitting position of the launch rail 158, and the launch solenoid 154 that is synchronously controlled with the ball feed solenoid 145 of the ball feed mechanism 140 is excited and swings upward to rotate the launch handle 8. A game ball is launched toward the game area PA with a launch intensity corresponding to the operation amount (detected value of the launch volume 8a).

  Next, a characteristic configuration of the launch unit 100 schematically configured as described above will be described with reference to the drawings as appropriate. Here, FIG. 15 is a front view showing the outline of the mounting structure of the launch unit 100 attached to the game auxiliary board 25, and FIG. 16 is a plan view showing the outline of the attachment structure of the launch unit 100 attached to the game auxiliary board 25. 17 is a cross-sectional view showing a vibration isolating structure for the firing control board 160, FIG. 18 is a side view of the cutting member, and FIG. 19 is a schematic diagram for explaining the operation of the cutting member.

[Launching unit mounting structure I]
As described above, in the launch unit 100, the launch mechanism 150 is attached to the case main body member 120, and the ball feed mechanism 140 and the launch control board 160 are attached to the case lid member 130. In order to assemble the launch unit 100, the case lid member 130 is formed by overlapping the case lid member 130 from the front side of the case main body member 120 so that the mechanical parts and the control board are covered by the case members 120 and 130. The locking piece 131c is locked to the side surface of the case main body member 120, and the case main body member 120 and the case lid member 130 are connected to each other, thereby obtaining a unitary launch unit 100 as a single unit.

  The firing unit 100 is fixed to the game auxiliary board 25 of the front frame 2 with screws using four fixing screws 101. As described above, the main body side insertion holes 121 are formed in the left and right and upper and lower four positions of the case main body member 120, and the case lid member 130 is aligned with the main body side insertion hole 121 and aligned with the left and right and upper and lower four positions. A lid-side insertion hole 132 is formed at a location. On the other hand, on the front side of the game auxiliary board 25, screw bosses 251 having screw holes (not shown) at four positions aligned with the main body side and the lid side insertion holes 121 and 132 are directed forward. A harness passage opening 252 that passes through the front frame 2 (game auxiliary board 25) in the front-rear direction and serves as a passage for the harness 173 is formed near the intersection of the diagonal lines connecting the four screw bosses 251.

In order to attach the launch unit 100 to the game assisting board 25, the rear side (case body member 120 side) of the launch unit 100 is opposed to the top of each screw boss 251. The fixing unit 101 is inserted into the main body side and the lid side insertion holes 121 and 132 and screwed into the screw holes of the screw boss 251 so that the firing unit 100 is brought into contact with the top of the screw boss 251. It is fixed to the game auxiliary board 25 with screws in a standing posture. The launch unit 100 abuts on the top of the screw boss 251 so that the game auxiliary board 25
Since the screw boss 251 is fixed at an interval corresponding to the height of the screw boss 251, the firing solenoid 154 protruding rearward from the case body member 120 can be accommodated within the interval.

  At this time, the launch control board 160 disposed on the front side of the front frame 2 and the payout control board 47 disposed on the back side of the front frame 2 (that is, the back set board 40) are transferred to the payout control board 47. The harness-side connector 173C of the harness 173 that is electrically connected is electrically connected by being coupled to the board-side connector 163C mounted on the launch control board 160, whereby the two control boards 47, 160 are connected. Can be transmitted.

  Thus, when the board-side connector 163C and the harness-side connector 173C are coupled, the harness 173 connected thereto extends rearward along the left side surface of the firing unit 100 and then bends inward in an L shape. The payout unit is routed along the rear surface of the launch unit 100 and passes through the harness passage opening 252 opened in the game auxiliary board 25 to the back side of the front frame 2 (that is, the payout disposed on the second back set board 45). It is pulled out (toward the control board side 47).

  Accordingly, the harness 173 can be drawn from the harness passage port 252 to the back side of the front frame 2 without exposing the harness 173 when viewed from the front side of the launch unit 100, so that the harness 173 is accessed from the front side of the pachinko machine PM. It will be very difficult to do. Therefore, it is possible to make it difficult to pull out the harness side connector 173C from the board side connector 163C by pulling the harness 173, and it is possible to effectively prevent an illegal act on the launch control board 160.

[Launching unit mounting structure II]
In a state where the launch unit 100 is attached to the front side of the game assisting board 25, the launch unit 100 and the speaker 26 are disposed close to each other. More specifically, a space sufficient to pass the harness 173 is formed between the left side wall 131b of the case lid member 130 and the right side wall 26a of the speaker 26. The board side connector 163C is connected to the harness side. Even if the connector 173C is pulled out, there is not enough space between the firing unit 100 and the speaker 26 to move the harness side connector 173C in the removal direction (left direction) with respect to the board side connector 163C. Release of the electrical connection of the connectors 163C and 173C is restricted.

  Therefore, it is difficult to pull out the harness-side connector 173C from the board-side connector 163C without removing the launch unit 100 from the game auxiliary board 25 of the front frame 2, and illegal acts on the launch control board 160 can be effectively prevented. Is possible.

[Launching unit mounting structure III]
As described above, the upper ball tray 30 is attached to the front of the game assisting board 25 to which the launch unit 100 is attached so that it can be opened and closed laterally by the hinge mechanism 22, and the pachinko machine PM is used for the game. In this state, the ball tray locking device 23 is used to hold the ball tray closed state that covers the front surface of the game assisting board 25. In this ball tray closed state, the firing unit 100 and the contact plate 31 of the upper ball tray 30 face each other in the front-rear direction, and between the front end portion of the launch unit 100 and the rear end portion of the contact plate 31, The unit 100 and the upper ball tray 6 are configured to have a predetermined interval for preventing transmission of vibration between them. That is, the launch unit 100 and the contact plate 31 are not in contact with each other in the ball tray closed state.

Here, the size of the gap formed between the firing unit 100 and the upper ball tray 30 is such that the case lid member 130 is relatively moved in the front-rear direction from the case body member 120 in order to open the firing unit 100. It is formed smaller than the relative movement amount for separating. For example, the distance C1 that is the shortest distance between the upper ball tray 6 and the launch unit 100, that is, between the ball feed duct 35 formed on the rear surface side of the upper ball tray 6 and the case lid member 130 in the launch unit 100. The front-rear distance C <b> 1 is not an interval large enough to open the unit case 110.

  Therefore, even if the unit case 110 of the launch unit 100 is to be opened, the relative movement of the case lid member 130 with respect to the case main body member 120 is restricted by the back surface of the upper ball tray 30 (ball feed duct 35). 6 can be made difficult to open the unit case 110 of the launch unit 100 without opening it to the game auxiliary board 25 (front frame 2), and illegal acts against the launch unit 100 (mainly the launch control board 160) can be prevented. It can be effectively prevented.

  Further, the distance C2 between the contact plate 31 of the upper ball tray 30 and the case base wall 131a of the launch unit 100 is set to a fixing screw (male screw) 101 for fixing the launch unit 100 and a screw boss of the game auxiliary board 25. The launch unit 100 is formed without opening the upper ball tray 30 by forming the screw 251 so as to be smaller than the screwed length with the screw hole (female screw) 251 so that the fixing screw 101 cannot be removed when the ball tray is closed. It is possible to make it difficult to remove the game assisting board 25 from the game assisting board 25, and it is possible to more reliably prevent an illegal act on the launch unit 100.

[Anti-vibration structure for launch control board]
Since the launch control board 160 built in the launch unit 100 is configured to dislike vibration, in this embodiment, in order to prevent the vibration when the launch mechanism 150 is operated from being transmitted to the launch control board 160, the An attachment structure using a vibration member 180 is employed. The firing control board 160 is attached not to the case body member 120 to which the firing mechanism 150 is attached but to the other case lid member 130 so that vibration from the firing mechanism 150 is not easily transmitted.

  On the printed wiring board 161 of the firing control board 160, board mounting holes 168 for fixing the firing control board 160 to the case lid member 130 with screws are formed through the front and back surfaces at only four locations. On the other hand, the case lid member 130 is formed with a holder portion 131d that partitions and forms the second storage chamber 133b for receiving the control module 162, and the launch control board 160 is placed on the holder portion 131d. Screw holes (not shown) for screwing through vibration-proof members 180 (details will be described later) are formed at four locations at the same pitch as the board mounting holes 168.

  The holder portion 131d is integrally formed with a surrounding wall portion 131e having an inner edge size slightly larger than the outer edge portion of the printed wiring board 161 of the firing control board 160 and extending rearward from the side of the holder portion 131d. Has been. The surrounding wall portion 131e functions as a positioning reference when the firing control board 160 is attached to the case lid member 130. When the outer edge portion of the firing control board 160 is inserted in accordance with the inner edge portion of the surrounding wall portion 131e, the printed wiring board Since the board mounting hole 168 of 161 and the screw hole (not shown) of the holder 131 are aligned, the board mounting screw 169 can be easily inserted. At this time, the four board-side connectors 163C to 166C mounted on the printed wiring board 161 are aligned with the case opening 134 of the case lid member 130 and exposed to the outside of the case.

  The anti-vibration member 180 is a washer formed in a hollow cylindrical shape using an elastic material (for example, rubber, soft synthetic resin, etc.) that can attenuate external vibrations, and has a screw for mounting a substrate at the center thereof. It has a screw insertion hole (not shown) into which 169 can be inserted.

In order to assemble the firing control board 160, the screws 169 are inserted into the board mounting holes 168 of the printed wiring board 161 from the back side of the payout control board 160 in a state where the firing control board 160 is placed on the four vibration isolation members 180. Then, after being inserted into the screw insertion hole of the vibration isolation member 180, it is attached to the inner surface side of the case lid member 130 by being screwed into the screw hole of the holder portion 131d.

  Therefore, the firing control board 160 is attached to the case lid member 130 via the vibration isolating member 180, and vibration generated when the firing mechanism 150 is operated in a state where the case main body member 120 and the case lid member 130 are coupled is prevented. Absorption by the vibration member 180 and transmission to the firing control board 160 are prevented.

[Measures for thread suspension]
In a normal game on a pachinko machine PM, in principle, the passing of a game ball to the winning detector is detected only once per game ball. However, in recent years, one gaming ball dropped into the winning device has been illegally used. In many cases, an illegal winning action (a so-called “thread-hanging goto action”) in which a large number of prize balls are paid out by passing continuously through the detection port of the win-winning detector by frequent operations.

  An outline of this typical technique is as follows. First, one end side of a filamentous body such as a fishing line having a predetermined length is fixed to a game ball, and the other end side of this filamentous body is grasped by a palm himself, A game ball (hereinafter referred to as a “threaded ball”) that has been crafted in such a manner is held between other game balls stored in the ball tray portion 32, and one ball from the ball tray portion 32 together with the other game balls. Each of them is sequentially supplied to the launch unit, and is launched by the launch mechanism and sent into the game area PA of the game board 10. When the threaded ball reaches the game area PA, a strong magnet is used from the outside of the glass frame 5 to win the threaded ball (a general winning device with the largest number of award balls tends to be targeted). ) To drop into the winning opening of the winning device. When the threaded ball flows down from the winning opening and passes through the detection opening of the winning ball detector, the main control board 18 detects the winning of the game ball based on this detection signal, and the payout control board 47 responds to the winning conditions. A predetermined number of prize balls are paid out from the prize ball payout device 42 to the upper ball tray 30. The fraudster recognizes that the threaded ball has reached the target winning ball detector when the prize ball is paid out in this way, and the other end side of the filament held in his palm By pulling the ball forward or sending it to the back side, the filamentous body is repeatedly passed through the detection port of the winning ball detector many times, thereby making it possible to illegally detect consecutive winnings of game balls and to make numerous prizes. Have won the ball. This is the whole picture of fraudulent prize-winning acts using threaded balls, which are frequently occurring recently.

  Therefore, in order to prevent such an illegal winning action, the launch unit 100 is provided with a fraud prevention tool (details will be described later on a cutting member 190) in the ball feed mechanism 140.

  The sphere supply passage 136 formed in the case lid member 130 of the unit case 110 extends in the left-right direction from the upstream sphere introduction path 137 to the downstream sphere extraction path 138. In the portion of the ball outlet 139, the extending direction is bent at a right angle (front-rear direction). Therefore, the ball feeding direction to the firing mechanism 150 by the ball feeding mechanism 140 can be substantially regarded as the front-rear direction. On the other hand, since the launch rail 158 on the downstream side of the ball exit 139 extends obliquely leftward and upward from the hitting position of the hammer 151 toward the launch port 111, the firing direction of the game ball by the launch mechanism 150 is an obliquely upward left direction. Can be considered. In this way, in the ball path in the launch unit 100, the direction changing portion that switches the path direction in the ball path (sphere lead-out path 138) of the ball feed mechanism 140 and the ball path (launch rail 158) of the launch mechanism 150, More specifically, a cutting member 190 capable of receiving and cutting the filament I passed through the ball supply passage 136 is provided in the vicinity of the ball outlet 139 in the ball feeding mechanism 140.

The cutting member 190 is formed in a thin plate shape using a metal material such as carbon steel or stainless steel. The main body 191, a trough 193 formed at the open end 192 of the main body 191, and the trough And a V-shaped groove 195 continuously formed in a narrow groove shape from the bottom portion 193a of 193. The main body portion 191 is formed with oblique sides 192a and 192a that are inclined inwardly from the pair of open ends 192 and 192, and a valley portion 193 that is gradually narrowed by the oblique sides 192a and 192a is formed. Yes. The V-shaped groove 195 is formed with blade portions 195a and 195a extending along the plate pieces 191a and 191a facing each other, and the facing blade portions 195a and 195a are received by the V-shaped groove 195. It is comprised so that a filament can be cut | disconnected. The cutting member 190 is attached by fixing the base end side attachment portion 191b to the back wall 136a of the ball supply passage 136 by means such as spot welding (see FIGS. 11 and 13).

Next, the operation of the cutting member 190 will be outlined. When Itozuke ball B _I in the game ball that is stored in the upper ball tray 30 is present, the ball feed duct 35 from the upper ball pan 30 the yarn with balls B _I other game ball (legitimate game balls) with Then, it flows down the ball supply passage 136, is sent to the launch position of the launch rail 158 one by one by the ball feed mechanism 140, and is launched toward the game area PA by the hammer 151 of the launch mechanism 150. In this case, filaments I secured to the thread with balls B _I
When pulled by a fraudster while being passed from the ball supply passage 136 to the firing rail 158, tension is generated to stretch straight due to the momentum of the hammer 151 of the firing mechanism 150. At this time, in the ball path in the launch unit 100, the direction change unit that switches the path direction in the ball path (sphere lead-out path 138) of the ball feed mechanism 140 and the ball path (launch rail 158) of the launch mechanism 150, Since the cutting member 190 is provided in the vicinity of the ball outlet 139 with the open end 192 facing the ball hitting position, the filament I connected to the threaded ball B _I launched by the firing mechanism 150 is Enter from the open end 192,
It abuts on any one of the oblique sides 192 a forming the valley 193 and is guided to the bottom 193 a of the valley 193. The filament I enters the V-shaped groove 195 formed continuously from the valley 193, and is cut while contacting the blade 195a while restricting its operation.

Thus, illegal because actors can be cut in contact with the easily cut member 190 filaments I manipulate, fraudulent winning act of detecting a winning of game ball thread with balls B _I was rigged It can be effectively deterred.

  The main effects achieved in the present embodiment described above are summarized as follows.

  First, when the launch unit 100 is fixed to the game assisting board 25 of the front frame 2 by a fixing screw 101, the launching unit 100 is viewed from the front (front) of the pachinko machine PM. A harness passage opening 252 through which the harness 173 that electrically connects the launch control board 160 and the payout control board 47 is passed is formed at a position hidden by. Accordingly, the harness 173 can be drawn from the harness passage port 252 to the back side of the front frame 2 without exposing the harness 173 when viewed from the front side of the launch unit 100, so that the harness 173 is accessed from the front side of the pachinko machine PM. It will be very difficult to do. Therefore, it is possible to make it difficult to pull out the harness side connector 173C from the board side connector 163C by pulling the harness 173, and it is possible to effectively prevent an illegal act on the launch control board 160 and the harness 173.

  Secondly, since the speaker 26 for restricting the removal of the harness side connector 173C from the board side connector 163C is disposed in the vicinity of the launch unit 100 on the front side of the front frame 2, the launch unit 100 is disposed. It is possible to make it difficult to pull out the harness-side connector 173C from the board-side connector 163C without removing it from the game auxiliary board 25 of the front frame 2, and it is possible to effectively prevent an illegal act on the launch control board 160.

Thirdly, the front surface of the unit case 110 and the rear surface of the upper ball tray 30 (ball feed duct 35) are spaced apart from each other with a predetermined interval C1. When the game assisting board 25 is in the closed position, the case lid member 130 is formed in a size that prevents the case lid member 130 from being opened relative to the case body member 120 (the size here is “distance”). Therefore, even if the unit case 110 of the launch unit 100 is to be opened, the relative movement of the case lid member 130 with respect to the case main body member 120 is restricted by the back surface of the upper ball tray 30 (ball feed duct 35). 6 can be made difficult to open the unit case 110 of the launch unit 100 without opening it to the game auxiliary board 25 (front frame 2), and illegal acts against the launch unit 100 (mainly the launch control board 160) can be prevented. It can be effectively prevented. Further, it is possible to prevent the launch unit 100 from being damaged due to external factors.

  Fourth, the firing mechanism 150 is attached to the case body member 120, and the payout control board 160 is attached to the other case lid member 130 with a vibration isolating member 180 capable of absorbing vibration generated by the operation of the firing mechanism 150 interposed therebetween. It has been. Therefore, the firing control board 160 is attached to the case lid member 130 via the vibration isolating member 180, and vibration generated when the firing mechanism 150 is operated in a state where the case main body member 120 and the case lid member 130 are coupled is prevented. Absorption by the vibration member 180 and transmission to the firing control board 160 are prevented.

  Fifth, a ball lead-out path (first ball passage) 138 that is formed in the ball feeding mechanism 140 and sends a game ball from the ball feeding mechanism 140 to the launching mechanism 150, and a launching mechanism 150 that is formed in the launching port 111. The launching rail (second ball passage) 158 extending toward the center and the thread passing through the ball passages 138 and 158 are received in the vicinity of the direction changing portion where the passage direction is switched, that is, in the vicinity of the ball outlet 139. Since the cutting member 190 that can be cut is provided, the filament I that tends to be stretched (tension is generated) easily by being pulled by a fraudster or by the momentum of striking with the hammer of the firing mechanism 150 is easily obtained. The cutting member 190 can be brought into contact with and cut. Accordingly, it is possible to effectively prevent an illegal winning action that illegally operates a game ball with a filament I such as a fishing line to detect a winning of the game ball.
