Abstract

PURPOSE:To prevent a player from being given with disadvantage by surely detecting the shortage of balls in a ball leading trough by axially installing a plurality of stepping levers in the ball leading trough for leading balls from a storage tank and allowing a ball shortage detecting switch to operate and send out a ball shortage detection signal even if a certain stepping lever turns. CONSTITUTION:When a ball which drops from a ball drop port 17 of a storage tank 9 is deflected by a certain reason, and one between the first and the second stepping levers 46 and 47 turns in the rising direction on the upstream side, even if the first or second stepping lever 46 or 47 swings, a ball shortage detecting operating member 56 swings, since the first and second operating pieces 58 and 60 are set close to a receiving part 54 from above. And a ball shortage detecting switch 62 operates to send out a ball shortage signal. Therefore, even if the ball is deflected in a ball leading trough 10, the ball shortage detecting switch 62 surely sends out the ball shortage signal, and a ball supplying device operates to supply balls, and the motor of a winning ball processing mechanism stops operation, and the operation of a winning ball discharge mechanism is suspended temporarily.

Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention provides a plurality of treadle levers that are pivoted to a ball ejection gutter that leads out balls from a storage tank, and when any one of the treadle levers rotates. This invention relates to a pachinko machine in which a ball shortage detection switch is activated to send out a ball shortage detection signal.

<Prior art> A pachinko machine in which a treadle lever is pivoted to a ball outlet gutter, and when there is a shortage of balls, the treadle lever rotates and acts on a ball shortage detection switch to generate a ball shortage detection signal. is conventionally known. Such a pachinko machine had two ball flow channels formed in the ball outlet gutter, and a treadle lever.

<Problems to be Solved by the Invention> However, recent pachinko machines require multiple prize ball ejecting devices to eject a larger number of prize balls, or the need to fill the prize ball ejecting device with balls. In order to shorten the time required, a large number of ball passages may be formed in the ball drain gutter. If a pachinko machine like this has a single treadle lever,
If a ball that has fallen from the storage tank is unevenly placed in the ball outlet gutter, the treadle lever will not rotate, making it impossible to detect a lack of balls. It may also be possible to provide a treadle lever for each ball channel, but this would require a large number of ball shortage switches depending on the number of treadle levers, which would complicate the structure.

<Means for Solving the Problems> The present invention has been proposed in view of the above-mentioned problems.
In a pachinko machine equipped with a ball outlet gutter where the two-wheeled part is positioned and the balls that fall from the lower mouth of the storage tank are arranged in a predetermined plurality of rows and then flowed down, a ball shortage detection switch is installed below the ball outlet gutter. At the same time, a ball shortage detection actuating member is provided to activate the switch pressure part that acts on the ball shortage detection switch, and the downstream side is pivoted to the end part of the slope of the bottom of the ball discharge gutter, and the upstream side is "A plurality of treadle levers pointing in three directions are arranged in parallel in the width direction of the ball outlet gutter, and the operating portions protruding from each treadle lever face the receiving portions of the ball shortage detection actuating member, respectively. It is.

<Function> When the ball becomes uneven in the ball guiding gutter, the tread lever located at the part where the ball is missing rotates by a certain amount. When the treadle lever is rotated, the operating part of the treadle lever presses the receiving part of the ball shortage detection activation member, and the ball shortage detection activation member rotates, causing the third part of the switch to act on the ball shortage detection switch. do. Since the ball shortage detection member faces the acting portion of each treadle lever at the receiving portion, the receiving portion is pressed regardless of which treadle lever is rotated. Therefore, no matter which ball treadle lever rotates in the upstream direction due to a lack of balls, the ball shortage detection switch 1 will always issue a ball shortage signal.

<Example> Embodiments of the present invention will be described below based on the drawings.

As shown in Fig. 1, the pachinko machine has a front frame 3 hinged to one side of the machine frame 1 with hinges 2, 2 so that the front frame 3 can be opened and closed, and the window of the front frame 3 is closed from the front side. The glass frame 4 and the opening/closing panel 5 are hinged vertically, and a game board storage frame 6 is attached to the back side of the front frame 3 so as to cover the window from the back side, and the game board is placed inside the game board storage frame 6. 7 is removably attached,
On the back side of the game board storage frame 6, a back mechanism board 8 is removably attached, which is provided with back mechanisms such as a winning ball processing mechanism and a prize ball discharging mechanism for processing winning balls flowing out from the game board 7.

The prize ball ejection mechanism includes a storage tank 9 disposed on the upper part of the back mechanism panel 8, a ball ejection gutter 10 for ejecting the balls in the storage tank 9,
A rectifying gutter 11 that rectifies the balls flowing down from the ball deriving gutter 10, a first prize ball discharge device 12 that flows down a preset number of balls (for example, 13), and a predetermined number of balls (for example, 7). A prize ball ejecting unit l-14 that integrates the second prize ball ejecting device 13 that flows down completely, the first prize ball publishing device 12 and the second prize removing device 13, and the opening/closing panel 5 for the ball that has flown down. A prize ball discharge gutter 15 that discharges balls to an upper ball supply tray (not shown) provided on the surface, an overflow TA 16 that causes balls to overflow to a lower tray (not shown) when the upper ball supply tray is full of balls, etc. It is configured.

As shown in Fig. 6, the storage tank 9 has a box-like shape with the top and one side open, and on one side of the bottom there are four spheres lined up in the width direction under which taste buds of a size large enough to fall are placed. + 17 opened and descending towards the bottom 1117 of the taste bud ■1 slanted bottom 18
As shown in FIG. 6, a stepped portion 19 is formed along the length direction of the bottom surface 18, and a tapered portion 2 that slopes downward toward the lower taste bud 17 is formed near the open side surface and on the opposite side.
0.20, and on the open side of the coccal lower mouth 17 there is a bulge 21 that slopes downward toward the upper surface or the lower part of the taste bud +11117.
A ball leveling member 22, 22 is swingably hung from the lower surface of the bottom to flatten the balls in the ball outlet gutter 1O.

The stepped portion 19 of the bottom surface processing 8 described above is designed to allow the balls supplied from the supply device (not shown) of the upper blade to flow down towards the coccus lower opening 17, and the ball flow of the fine ball lead-out lO. The number of channels (four channels in the embodiment shown in the drawings) allows the balls to flow down almost evenly, thereby preventing the balls from concentrating or becoming insufficient in a particular flow channel.

Further, as shown in one drawing, the storage tank 9 is provided with a shutter member 23 that can open and close approximately half of the taste bud f opening 17. As shown in FIG. 9, the partial shutter blade 23 has a plate whose width is approximately half the width of the ball drop opening 17, and has a rod-shaped operating knob 24 protruding from the minus side. In order to slidably support this shutter member 23, a slide groove 25 is formed horizontally on the lower surface of the storage tank 9, and a horizontally elongated slide hole 26 is formed in a portion facing the opening of the slide groove 25. The operating knob 24 is passed through the slide hole 26 and both sides of the shutter member 23 are fitted into the slide groove 25 to support the shutter member 23 so as to be slidable in the longitudinal direction of the storage tank 9. The storage tank 9 equipped with the shutter member 23 having the above-mentioned configuration is connected to the ball flow lower passage 4.
When used with the ball outlet gutter 10 in the rows, move the shutter member 23 to the right side in Figure 9 to open all the ball drop openings 17 to prevent the internal balls from falling into the four ball channels. Make it fall. Note that the lever-shaped first hole 26'' is inserted into the slide 1.
Since the locking member 27 is eccentrically set in the 1i11 movement f+f function, the first locking member 27 is rotated to lock it to the operation knob 24, as shown in No. 81'A. In other words, when the shutter member 23 is locked, it is possible to prevent the shutter member 23 from moving due to vibration or the like. On the other hand, when the storage tank 9 is used with a ball flow passageway or two ball guideways 10,
Pinch the operating knob 24 and move it to the left side in Figure 9, close half of the ball drop opening 17 with the shutter member 23, and close the second
It is locked by the locking member 28. In this way, when half of the ball dropout port 17 is closed, the balls will fall from the open part, and will fall under the two pitches of the ball outlet gutter 10 without spilling outside. A ball flows down into the road.

In order to attach the storage tank 9 having the configuration described above to the back mechanism panel 8, a fastener 30 is passed through the lug 29 protruding from the side surface of the storage tank 9, and a fastener 30 is inserted as shown in FIG. 1 pig + l

To attach the storage tank 9 using this fastener 30, as shown in FIG. In this state, the tip of the outer member 35 is inserted into the fixing hole 31 of the ear piece 29 of the storage tank 9 and into the fixing hole 31 of the back mechanism panel 8, and then the operation knob 33 is pushed in. When operated in this way, the large diameter portion 32 at the tip pushes out the leg portions 34, so that the leg portions 34, as shown by solid lines in FIG.
. . . It is possible to securely lock onto the opening edge of the locking hole 31 and easily lock the storage tank 9 to the opening. To remove the storage tank 9, pull out the operating knob 33 as shown by the chain line in FIG. In this way, the large diameter part 3 at the tip
2, the distance between the tips of the legs 34... decreases due to elasticity, and the Ih hole 3
You can get Zuko from 1.

The ball deriving gutter 10 which derives the balls from the storage tank 9 is the thirteenth
As shown in FIG. 20, the first main partition walls 37 on both sides
, the second main partition wall 38 and the third main partition wall 39 in the center divide the flock into two in the width direction. By erecting the partition wall 40, the first flow path 41 and the second flow path 42 are defined, and the third main partition wall 39 and the second main partition Q? 38
By erecting the second sub-compartment wall 43 between them, a third flow passage 44 and a fourth flow passage 45 are formed. Bottom slope”1
A first tread lever 46 is placed at the end portion, and a second tread lever 47 is placed beside the inclined upper end portion of the bottom of the third flow passage 44 and the inclined upper end portion of the bottom portion of the fourth flow passage 45, and each swings separately. In this state, the lower end side of the inclined bar, that is, the downstream side, is supported by the shaft 48,
The second treadle lever 4 is biased by the sublink 49 and the weight in the direction of upward tilt, that is, the upstream side.
At the sloping upper end portion of 7, a substantially hook-shaped lock member 51 is rotated, which forcibly lowers and locks the slanted upper end portion of the second tread lever 47 by rotating the knob 50. It is pivoted so that it can move. In this way, the second tread lever 4
7 is locked by the locking member 51, the storage tank 9
When used with half of the ball outlet 17 closed by the shutter member 23, the second tread lever 47 does not rise even if there is no inflow of balls, and can be used in the same way as if there were balls. can.

The bottoms of the first flow path 41 and the second flow path 42 located on the downstream side of the first footplate lever 46, and the third tltf and lower passage 44 located on the downstream side of the second footplate lever 47
and ff14 flow passages 45 have slits 1-52 wide enough to prevent the balls from falling into them, and slits 52 that pass through the covering material made of stainless steel plate or the like at the bottom of each inclined lower end portion. It is applied in state 11 covering the edges of. Further, as shown in FIG. 16, a receiving portion 5 is provided at one end below the first tread lever 46 and the second tread lever 47.
4 on the right side, and a ball shortage detection actuating member 56 on the other end of which the switch suppressing portion 55 is on the right side is swingably mounted on a shaft 57, and a ball shortage detection switch 62 is provided.
The pin 5 of the first action piece 58 protrudes from one end as an action part.
9 and the bottle 61 of the second operating piece 60 protruding from one end of the second treadle lever 47 as an operating member 5.
The receiving portion 54 at one end of the ball shortage detection switch 62 is made to face from above, and the other end of the ball shortage detection activation member 56 is made to face the activation protrusion 62' of the ball shortage detection switch 62.

In addition, the ball outlet gutter 10 (not shown in the drawings) has an operating portion 63 at one end below the receiving portion 54 side of the ball shortage detection actuation member 56 in order to enable the ball-foot detection actuation member 56 to be switched to the locked state. A lock 1 member 65 having a cam protrusion 64 in the middle is rotatably provided by a lock 166. When the lock shaft member 65 is moved 1-11 and the receiving portion 54 of the ball shortage detection activation member 56 is held in the raised state by the cam projection 64, the switch 2 suppressing portion 55 or the activation projection 62 of the ball shortage detection switch 62 is moved.
There is no need to press '. Therefore, in an assembly factory or the like, other mechanisms can be checked in this locked state, and checking can be performed even when the storage tank 9 and the ball outlet gutter 10 are not filled with balls.

The above-mentioned through slit 52 has the function of dropping balls and the function of supporting the ball in point contact to reduce rolling resistance, and the covering material has the function of further reducing rolling resistance and wear. . Moreover, the effective height of the first sub-compartment wall 40 and the second sub-compartment wall 43 on the upstream side becomes lower and the effective height on the r-stream side gradually becomes il;Ji<shi.

In order to attach the ball guiding gutter 10 to the back mechanism panel 8, the sloped upper end portion, that is, the first and second tread levers 4
6.47 should face the ball drop opening 17 of the storage tank 9 from below, and be inserted into the through-hole of the mounting piece 67 formed at an appropriate location (in the embodiment shown in the drawings, the sloping upper end portion and the sloping lower end portion). A fastening tool 30 similar to the above is passed through, and this fastening tool 3
Attaches removably by o... When the ball extracting maple 10 is attached to a predetermined position on the back mechanism panel 8 in this manner, the ball leveling member 22 22 suspended from the storage tank 9 faces each flow path from above. When the balls are sufficiently stored in the storage tank 9, these balls fall from the ball drop port 17 and land on the first tread lever 46 and the second tread lever 47, upstream of both tread levers 46 and 47. The free end side that is the side, that is, the slanted end part is lowered to the first. Second action piece 58.6
Raise 0. Therefore, as shown in FIG. 17, the switch pressing portion Ff of the ball shortage detection actuating member 56 does not press the actuating protrusion 62'. The ball shortage detection switch 62 is of a normally open type which does not conduct when the actuating protrusion 62' is not pressed, and becomes conductive when the actuating protrusion 62' is pressed. Therefore, the ball shortage detection actuating member 5
When the switch pressing portion 55 of No. 6 is in a lowered state, the ball shortage detection switch 62 does not send a ball shortage signal. ) 751 The balls placed on the tread lever 46 and the second tread lever 47 are not aligned in a line by the first sub-compartment wall 40 and the second sub-compartment wall 43 as they flow down. The water flows down into the flow path 42, the third flow path 44, and the fourth flow path 45 at a substantially average rate. In addition, the first
．． The height of the second sub-compartment walls 40° 43 increases from the bottom toward the downstream side, so that it is possible to ensure that the balls are aligned in a line in either the left or right flow path as they flow down. It is composed of In addition, the vertically stacked balls collide upon contact with the ball leveling member 22, 22, so that they are almost leveled into one layer. Then, the number of balls in the storage tank 9 gradually decreases.

When the number of balls resting on the first tread lever 46 and the second tread lever 47 decreases or disappears, the force of the splinter 49 raises the upstream side (free end side) of both tread levers 46 and 47, and The first working piece 58 and the second working piece 60 are lowered to the receiving part 5.
Press down on 4. Therefore, the ball shortage detection actuating member 56
The switch pressing FE section 55 rises and presses the operating protrusion 62' of the ball shortage detection switch 62, thereby making the ball shortage detection switch 62 conductive and sending out a ball shortage signal. Further, one end of the swinging rod 68 is connected to a portion protruding downward from the lower surface of the first tread lever 46, and the upper end of the rod 69 is connected to the other end of the swinging rod 68. When the lever 46 rises due to a lack of balls, the operation of the ball supply mechanism is locked via this rod 69, thereby stopping the supply of shot balls.

In addition, if the ball that has fallen from the ball drop port 17 of the storage tank 9 is biased for some reason and rotates in the upstream direction of either the first tread lever 46 or the second tread lever 47, the embodiment shown in the drawings The first working piece 58 and the second working piece 6
0 faces the same receiving portion 54 from above, even if either the first tread lever 46 or the first tread lever 46 swings, the ball shortage detection actuating member 56 swings, This activates the ball shortage detection switch 62 and sends out a ball shortage signal. Therefore, even if the balls are uneven in the ball outlet gutter 10, the ball shortage detection switch 62 reliably sends the ball shortage signal, thereby operating the ball supply system and replenishing the balls. In addition, the motor of the winning ball processing mechanism, which will be described later, stops operating, and the operation of the winning ball discharging mechanism is temporarily stopped. In the embodiment shown in the drawings, the first tread lever 46 is connected to the ball supply mechanism, but the second tread lever 47 may be connected, or both the tread levers 46 and 47 are connected to the operating piece. 58
．． 60 and the receiving portion 54 may be communicated through mechanical means such as the receiving portion 54. When balls are replenished into the storage tank 9 based on the ball shortage signal from the ball shortage detection switch 62, the first. The second treadle levers 46 and 47 both swing back down the sloped upper end, and the ball shortage detection switch 62 stops sending out the signal. Then it returns to a playable state.

The balls flowing down the ball outlet gutter 10 are reliably rectified by the rectifying gutter 11 before being led to the prize ball discharging unit 14.

As shown in FIG. 21, the rectifying gutter 11 has a ball channel 71 which extends in a horizontal U-shape from a ball-containing lower shaft opening laterally, and whose downstream portion is bent into a substantially step-like shape. . The ball-containing lower 0 has a height that is approximately twice the diameter of the ball or more, and has a bottom shape that decreases in height toward the downstream side. So, ball guide gutter 10
Even if the balls flowing down are stacked one on top of the other, they collapse when entering the rectifying gutter and are reliably aligned step by step in each channel.

In the embodiment shown in the drawings, the prize ball ejecting unit 14 includes a first prize ball ejecting device 12 that, when activated once, causes 13 balls to flow down as prize balls, and a second prize ball ejector that flows down 7 balls as prize balls.

The second driving piece 183 provided at the upper end is engaged in the second engaging groove 117 of the second regulating member 107 described above.

Motor 16() is 'l';'l' If! When J is activated and C is rotated, the second gear If89 or the first gear 88 is rotated.
The first driving force member 86 presses the first drive receiving portion 87 of the first winning ball processing member 82 to rotate the first winning ball processing member 82 against the bias of the spring 84, and the first winning ball is rotated. The receiving part 81 is moved from the exit side of the first winning ball collection path 78 to the winning ball discharge port 110 side. At this time, if there is no ball in the first winning ball receiving part 81, the first ball sensing member 1.02 does not rotate because there is no part protruding from the outer periphery of the first winning ball processing member 82. Therefore, the first prize ball ejecting device 12 does not operate. Then, when the first drive cam 86 further rotates, it comes off from the first drive receiving part 87, and the first winning ball processing member 82 rotates back by the urging of the splinter 84, and the first winning ball receiving part 81 are returned from the winning ball discharge port 1.10 side to the exit side of the first winning ball collection path 78.

Next, the winning balls flowing out to the back side of the game board 7 are collected by the first winning ball collection gutter 76, and when the winning balls flow down the first winning ball collection path 78 and reach the exit, the winning balls are collected as the first winning balls. 1
Fits into the first winning ball receiving part 81 of the winning ball processing member 82,
The two-hand portion is made to protrude from the outer circumferential surface of the first ball processing member 82. In this state, when the first winning ball processing member 82 is rotated by the drive of the first drive cam 86, the spherical surface of the protruding ball will first rise above the lower end of the first tamper-proofing member 101 and touch the first tamper-proofing member 10]. When the first winning ball processing member 82 is rotated to remove the first lock protrusion 106 from the first receiving piece 107 of the first ball sensing member 102 and the first winning ball processing member 82 is further rotated, the spherical surface of the ball is moved to the first receiving piece 107 of the first ball sensing member 102. It acts on the first ball sensing section 105 to rotate the first ball sensing member 102 .

Due to this rotation of the first ball sensing member 102, the tenth point 10
9 rises and activates the first prize ball ejecting device 12. Therefore, by the operation of the first prize ball discharging device 12, 13 balls are discharged into two trays as prize balls. In this way, the first
When the ball that has activated the prize ball discharge device 12 advances further due to the rotation of the first prize ball processing member 82, it comes off the first ball sensing section 105 and falls from the first prize ball receiving section 81, and enters the prize ball discharge port. 110 and is discharged to the outside of the pachinko machine. 1st
When a winning ball falls from the winning ball receiving part 81, it comes off from the first drive cam 86 or the first driving receiving part 87, and the first winning ball JIF member 82 is rotated back by the force of the sprinter 84. and returns to the exit side of the first winning ball collecting path 78 from the first winning ball receiving section 81 or the winning ball outlet 110 side. Since the motor 100 is constantly operating, when a winning ball is generated, the first winning ball flow down control device 74 repeats the above operation and operates the first winning ball discharging device 12 every time it is processed.

The second prize ball flow down control device 75 also operates in the same manner as the first prize ball flow down control device 74, and the second prize ball discharge device 13 is activated once every time one winning ball flows down, and a predetermined number of winning balls are flown down. For example, seven balls are flown down as prize balls.

In addition, in this embodiment, the number of prize balls discharged by the first prize ball discharge device 12 and the number of prize balls discharged by the second prize ball discharge device 13 are different, but the number of prize balls discharged by the first prize ball discharge device 12 is different, but By appropriately setting the number of balls to be attached to the ball support portion, it is possible to eject the same number of prize balls as the number of turns, or it is also possible to eject a different number of prize balls from the above embodiment.

Furthermore, in the above-mentioned embodiment, four ball flow paths were formed in the ball guide gutter and two treadle levers were provided, but the present invention is not limited to the above; You can change the number of .

In short, the action parts provided on the plurality of treadle levers are concentrated on one receiving part, and even if any one of the treadle levers rotates, the action part of the relevant treadle lever presses the receiving part, thereby detecting the lack of balls. Any configuration may be used as long as the switch pressing portion of the actuating member can actuate the ball shortage detector switch.

<Effects of IJJ> As explained above, according to the present invention, even if the ball is deviated in the ball ejection hole, one of the treadle levers rotates, and the rotation of the treadle lever activates the ball shortage detection switch. is activated. Therefore, even if there is a ball shortage detection switch, it is possible to reliably detect a ball shortage in the ball outlet gutter, and it goes without saying that it will not cause any disadvantage to the game center.
11B can be simplified. This is extremely useful in pachinko machines that are equipped with a plurality of prize ball ejection devices because there is not enough space.
