Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a back mechanism board of a pachinko game machine, and in particular, when a ball hit into the game board enters a winning area, this invention is electrically detected and a predetermined number of With the electronic control of the prize ball dispensing mechanism, the hanging part of the prize ball's falling path was shifted δ to one side of the back set board, unlike in the past. A prize ball dispensing device is installed in the middle of the hanging part, and the falling path of each pile of soil is integrated and overlapped with the back set board, making it possible to form a wide empty space in the center of the back of the game board. The structure has been designed to have the rigidity that was previously unavailable, making it compatible with the recently popular Lucky Seven-type pachinko machines, as well as improving the precision of remote centralized control using computers. Regarding the board.

As is well known, in a pachinko game machine, when a player drives a ball into the game board one by one using an RGT launcher installed at the bottom of the game board, the ball collides with an obstacle nail and falls while changing direction randomly. By entering the winning area with a certain probability on the way there, a predetermined number of 'X' balls are awarded to the player. Conventionally, the payout of prize balls in this manner is generally carried out by a physical force generated by a prize ball attached to the back of the game board being transmitted to the first player.
As shown in the figure, the prize balls were played using a mechanical prize ball dispensing device.

The back mechanism 220 in a conventional pachinko machine has a structure that is attached completely and flatly to the back of the game board, and has a reserve ball storage tank 224 in the upper part. Seven ball chutes 225 are installed separately to allow the spare balls to flow down and line up while making a U-turn δ in an S-shape, and a ball extraction gutter 231 is externally assembled in the lower part of the ball chute 225. At the center of the back of the game board, there is a prize ball payout mechanism section and a winning ball assembly @ 221, and at the bottom of the casing there is a controller 260 that stores simultaneous winning balls, separates them one by one, and lets them flow down, and a controller 260 that separates the winning balls one by one and lets them flow down. An operating lever 265 is provided which faces the winning ball ejection gutter 222 which rotates due to the weight of the ball, and the end of the operating lever 265 is connected via an interlocking rod 266 and a link mechanism 267 to allow the ball to be rotated by the winning ball. Transferring physical force to the prize ball case 268 provided at the end of the ball chute 225 to activate the ball chute 225,
A damper 2 with a predetermined number of prize balls arranged below it.
69, and the prize balls are caused to flow down the prize ball ejection path 236 to be paid out into a saucer in the front. From the 1970, an act hole 219 and an out ball trough 223 were provided in the center of the back mechanism 220 to accommodate out balls that did not win anywhere, and to discharge them to the outside of the 91 machine.

Therefore, conventional pachinko machines do not have r
The mechanical structure of the back mechanism 220 is complicated, and assembly and positioning adjustment are troublesome, and the space occupied by the components of the back mechanism 220 is large, making it difficult to have a sufficient empty space at the back of the game board. Can not. [The space for the M verb on the back of the L game board becomes narrower, and the flow path for the spare balls, winning balls, out balls, etc. in the storage tank 224 to be discharged from the machine becomes complicated. This has the disadvantage that it is difficult to see from the outside if it becomes clogged.

On the other hand, recent pachinko machines use a large variable input X device that uses an electric drive source to create a situation called Lucky Seven where a large number of prize balls are awarded. They have become popular with customers, and most machines are now equipped with large variable prize winning devices. However, in such large variable prize winning devices, the electric drive source often penetrates the game board and extends to the rear of the back set board, so it is difficult to use the conventional mechanical prize ball payout device. The back mechanism provided with such a variable prize winning device has the disadvantage that there is not enough space to extend such a variable prize winning device.

In addition, with the adoption of such a large variable prize winning device,
The chances of simultaneous or consecutive winning balls occurring are extremely high. However, in the conventional mechanical prize ball dispensing mechanism, the dispensing operation is a mechanical link motion as described above.
The payout cycle takes about an extra second, but current electric firing devices can fire 100 balls per minute. Tsuj,
9. (Because the ball stops hitting the game board every 16 seconds, a large amount of winning balls are generated in a short period of time, and the payout of prize balls cannot keep up, causing the winning balls to accumulate one after another.)

Therefore, a high-speed prize ball dispensing device is required, and a large amount of prize balls are to be paid out to players, so the flow of prize balls should be smoothed, the prize ball storage section should be enlarged, and so on. The need for structural reinforcement has arisen.

In addition, it is necessary to detect balls in order to count the number of falling balls in order to centrally manage the ball output rate and business results associated with the daily operation of pachinko machines. The structure of the ball, especially the winning ball discharge gutter, the out ball gutter, and the ball removal gutter, must not be functionally integrated. Then, there is a ball counting device that counts the total number of balls replenished into the storage tank and the total number of balls discharged outside the machine from the ball extraction gutter after closing, or winning balls and hit balls (a general term for winning balls and out balls). ) Is it necessary to place a ball counting device facing the lower end of the falling ball path to prevent the falling balls from flying out to the outside so that the balls can be detected reliably? #), this enables highly accurate centralized management.

This invention was developed against the background of I) above, and is a small electric motorized NFC device that operates based on a winning detection signal generated by electrically detecting a batted ball that enters a winning area. By adopting a high-speed prize ball dispensing device, the complicated and excessive competitive configurations such as the controller 260, operating lever 265, interlocking rod 266, etc. in the back mechanism are unnecessary, and the prize ball dispensing device is the main component. In order to make the entire Ura Gun borrowing compact, the falling paths of various balls are integrated and overlapped with the back setting board on which the back mechanism is set, and the hanging part of the prize ball falling path and the ball By shifting the exit channel to one side of the back setting board, it is possible to form a wide empty space in the center.
Moreover, the structure is made to have rigidity which could not be obtained in the past, so that it can cope with the Aratsuki-Seven type pachinko game machine which pays out a large amount of prize balls in a short period of time, which has become popular recently. That is,
This invention makes it possible to install a large variable winning device that protrudes from the back of the game board, and also enables the installation of a large variable winning device and the electrification of the prize ball payout device. In response to this, we have decided to make the falling paths of winning balls and prize balls simpler and more rigid than before, to make the flowing down of winning balls and prize balls smoother, and to ensure that each falling path and prize ball have a simpler and more rigid structure than before. The purpose is to improve the strength of the ball storage part so that it can withstand the falling and storage of a large amount of balls.

In general, the purpose of this BA is to functionally arrange the lower ends of the flow paths of various balls, and also to improve the accuracy of remote centralized control using the computer in the control room. shall be.

The present invention will be specifically explained below using the drawings.

Before explaining the embodiment of the back mechanism panel of the present invention, first, the equipment and management method of the pachinko parlor in which the pachinko game machine is installed will be explained with reference to FIG.

Pachinko parlors usually have multiple rows of island equipment, called a pachinko island, as shown in Figure 2.

On each pachinko island 100, a plurality of pachinko game machines 1, 1, and 2 are arranged in two rows with the backs of the game boards facing each other. It is movably mounted. ′! ! Pachinko Island 1
In the upper space 101 of 00, a pachinko ball supply gutter 102 is provided which is inclined at an appropriate angle.

A supply chute 10 branches out from this supply gutter 102.
A supply chute 103 is provided through which one payout ball can be supplied to each pachinko game machine 1 as a prize ball. , that is, the supply chute 1
03 is equipped with a replenishment device 104.The replenishment device 104 is installed in accordance with a command from a general control room (not shown).
The ball flowing through the supply gutter 102 is supplied from the supply chute 1o3 to the preliminary storage 824 at the top of each pachinko game machine 1.

Roughly speaking, in the center of the lower part of the pachinko island 100, there is a collection gutter 105 that collects the balls that have been collected and discharged from each pachinko game machine into one place. After being polished by a polishing machine, it is transported upward by a lifting device R (both not shown), and is then discharged into the supply gutter 102 again. In addition, the command to supply balls to each pachinko machine is as follows.

A signal from a lack of balls detector t'L provided at the lower part of the preliminary storage section U is sent to a computer in the general control room and is generated based on this information.

In this case, the replenishing device 104 can replenish a predetermined amount (for example, 400 balls) to the preliminary storage portion in one replenishment operation. Therefore, at a pachinko parlor, in addition to the number of replenished balls in each pachinko machine, for example, the number of paid balls and the number of balls played are calculated, the computer system, the ball output rate of each machine (-times of prizes), etc. It is possible to easily calculate the number of pitches x the number of winning pitches ÷ the number of batted balls and the sales results (number of batted balls - total number of supplies).

In order to streamline management by intensively collecting ball output rates and sales results as described above, it is necessary to detect each pile of soil.
As shown in FIG. 4 and FIG. 5, a ball receiving box 11o is installed on the back of the machine frame 2 at the lower rear of the game board, so that winning balls and out balls can be detected. This ball receiver has a winning ball receiver 111 and an out ball receiver 112 in a box 110.
The structure is such that the winning ball and the hit ball can be accurately detected separately.

Therefore, it is necessary for this ball receiver to functionally expose the exit of the winning ball ejection path and the exit of the out ball ejection path on the back side of the game board to the box 110. However, in the embodiment of the present invention, this requirement is met by configuring the back mechanism panel as described below.

Before going into the explanation of the embodiment of the back mechanism board, an example of the structure of the front side of the game board will be shown and briefly explained.As shown in FIG. A frame-shaped front frame 4 is attached to the machine frame 2 (see Fig. 4) in a substantially vertical position and is rotatably attached to the machine frame 2 (see Fig. 4) with a hinge 3 shown in Fig. 3; A glass storage frame 5 attached to the front frame 4 so as to be openable and closable, an opening/closing panel 6 attached to the lower part of the glass storage frame 5 so as to be openable and closable, and a glass storage frame 5 attached to the rear of the front frame 4. It is composed of a glass plate held in a storage frame of 5 yen and a game board 8 fixed at a distance of one foot.

The number of balls fed from the saucer 9 above is 1.
A batted ball launcher 10 is provided, and an operation dial 11 and an auxiliary tray 12 are provided on the front surface of the lower part of the front frame 4.The batted ball launcher 10 has the same structure as the already known batted ball launcher. Detailed explanation will be omitted since many parts are used.

On the front surface of the game board 8, there is a guide rail 13 that guides the ball hit by the ball launcher 10 to the upper part of the game board 8, and a guide rail 13 that randomly changes the direction of the ball falling upwards. A large number of obstacle nails 14 are fixed to
A winning checker 15 as a winning area, a winning machine 165165 winning tool F and a variable winning device 18 are provided at appropriate positions on the board surface.A guide rail is provided in the space between the glass plate held on the front frame 4. Surrounded by 13! C gaming section is formed δn. [L] At the bottom of this game section, the above-mentioned prize areas 15-
An out hole 19 is provided for collecting balls that fail to win a prize and return to the rear of the game board 8.

Then, on the back side of the game board 8, the above-mentioned award areas 15 to 1 are
The back side setting board 21 is attached to the entire surface so as to form a first space A having an interval that allows the ball hit from 8 to flow down. The various constituent mechanisms form a set of n in a polymeric manner.

A collection shelf 21a is provided below the first space A of the back set board 21, and the first space A is provided approximately at the center of the collection shelf 21a.
A winning ball ejection path 22 is provided which is continuous to 4 and has an exit formed on the lower end line of the front frame 4 by bending δn from the 1st space AI to the 2nd space A2 side in the middle. shi, above 1st
The winning balls that entered the space city A go through this winning ball discharge path 22.
Flowing down, the ball receiver at the rear of the game board is discharged toward a box 1100 and a winning ball receiver 111.

The collecting shelf section 21 &, which is formed so as to be inclined downward toward the central part, rectifies the generated winning balls one by one in a row and guides them to the winning ball discharge path 22. n
The winning ball detector 55 detects one ball, and the back cent board 2
Set above 1, n9 control device 50 yen memory circuit sequentially memorize.

Further, in the first space A□, an out ball discharge gutter 4 is provided corresponding to the out hole 19. Socket 11
The ball holder is placed in box 1 from the outlet section provided opposite to box 2.
It is designed to be discharged within 10 minutes.

Set the RS above the light surface of the front set board 21, and supply it externally? The spare ball storage section 24 for storing the spare balls to be stored is installed and the spare ball storage section 24 is fixed as shown in 1% No. It has a structure that can withstand the weight of An outflow port 24a is provided at the tip end of the lower slope of the preliminary storage section U, and below the outflow port 24a there are already sloped stones so large that the balls roll from the left to the right of the back setting board 21 under their own weight. A guideway 25 that bends downward at the right end of the spiral n1 and then descends approximately vertically is a continuous type n, and the end of this guideway 25 is the actual ball dispensing device 40.
connected to the inlet of the

The guideway 25 is as shown in FIGS. 6 and 7.

On the back of the back set board 21, there is a gutter-shaped second space A! A treadle lever 26 is provided at the bottom facing the outlet 24 so as to be freely tiltable, with one end protruding into the guideway 25, and a weight 27 at the other end. After installation, the ball shortage detector 56 is exposed in conjunction with the tilting movement of the treadle lever 26. This detects the presence or absence of balls in the preliminary storage section 24, and when the balls are depleted, it issues a ball shortage signal, contacts the general control room (not shown), and prompts for balls to be replenished.

In addition, the partition wall 25a is provided in such a manner that it gradually rises, and the hanging portion that descends approximately in the above-mentioned direction is provided so as to automatically align and guide the taxiway opening spare balls in one row and two rows. There are two complete rows.

In the middle of the taxiway 5, the ball pressure in the taxiway 25 changes slightly depending on how well the balls are stored in the preliminary storage part 24, and this prevents the balls from stacking up in two or three stages and causing a ball stuck phenomenon. In order to do this, a swingable ball plate is hung, and a ball holding plate 29 is provided which can be tilted by pivoting one end thereof.

A pressure release mechanism 30 is disposed at the bending portion 25b of the guiding path, and a socket for the ball removal path 31 is provided.

The bent portion 25b has a peripheral wall portion 32 with a structure fL, which can open and close a part of its outer circumferential surface, a swinging rod that swingably holds the peripheral wall portion 32, and an operating rod 34 that can freely tilt above the swinging rod. The locking portion 33jL of the swinging rod 33 and the convex portion 3 of the operating rod 34 are provided.
4& are configured so that they engage with each other, and when n1 is disengaged by an external operation, the peripheral wall 32 is opened and the spare ball is guided into the ball extraction path 31.

This ball removal passage 31 is arranged in parallel with the hanging part of the guideway 25 and is offset to one side of the back setting board 21, and a second space A that is branched at a bending part of the guideway 5 t'; At the same time, the lower part of the flow path is bent toward the first space A1 side, and is extended to the lower part of the pachinko game machine 1 to join the out ball discharge gutter. be. As a result, the balls that have passed through the ball ejecting path 31 and come out as many as m can be counted as balls that are ejected from the machine through the 110 yen box in the ball receiver as n1 balls.

A separation wall 113 is formed in the box 110 to separate the winning ball socket 111 and the out ball socket 112, and the winning ball socket 111 and the out ball socket 112 enter the ball socket below n1. Guide channel 11 that merges the balls and guides them as hitting balls
4 is provided, and the winning ball socket is located below the winning ball socket 111. In the middle of the guide trough 114, a hitting ball station 116 is provided to detect not only out balls but also winning balls and balls pulled out of the ball extraction path 31 as hitting balls.

In the upper layer execution row, the exit of the winning ball discharge path 22 is connected to the winning ball receptacle 111 of the ball receiving box 110, and the out ball discharge channel and the ball extraction path 31 are merged in the middle, and the exit is connected to the winning ball receiving box 110. 110
The out ball socket 112 is made to face seven n na functionally. -j In other words, by providing the exits of the winning ball discharge path 22 and the out ball discharge gutter n between the WA assistant storage and trade section 47, the winning balls and out balls are distributed to the left and right. Therefore, the winning ball socket 111 and the out ball socket 112 can be reliably separated, and the ball socket can prevent balls from getting mixed into the box 110 and balls from flying out of the box. As a result, the ball is box 1
By changing 10 to 7J\ type, the interior of the pachinko island was simplified.
At the same time, the accuracy of the data regarding the number of contributed balls and the number of balls hit sent to the general V storage will be improved. Using this data and the number of balls to be supplied to the preliminary storage section 24, it is possible to intensively collect the ball output rate and business performance using the method described above.

In the above case, at the time of closing the store, the spare balls in the reserve storage section 24 flow down the ball removal path 31 by the operation of the pressure release mechanism 30, and the ball receiver enters the box 110, where it is counted as a struck ball and sold. Grades will be calculated.

Reed. Driving ball sensor 11 provided in the guide trough 114
6 is designed to detect the rotation of the counting gear mounted so as to face the guide gutter 114 yen using a permanent magnet and a reed switch, and generate a detection signal of 1 pulse per rotation of the gear. .

In addition, the exits of the entered prize ball ejection path 22, out ball ejection gutter 23, and ball extraction path 31 are arranged in the first space or the exit of the ball receiving path 31 in order to functionally face each socket of the box 110 as described above. Although it is formed over the first space and the second space, it is not limited to this.

However, in relation to the ball receiving box 110, the winning ball ejection path 22 changes the flow path from the first space to the second space, making it easier to detect balls.

Furthermore, in the middle of the drooping part of the guideway 25, there is a flow-success detector 57 consisting of a detection plate 57a and a microswitch 57b facing into the -F:f'L channel for each row. The installation is such that abnormalities in the flow of spare balls due to stuck balls or dirt mixed in in the interrogation path 25 are monitored, and a command signal is output to the control device 50.

In one embodiment, an NFC electric prize ball dispensing device 40 connected to the lower end of the hanging portion of the guideway 25 is installed at the rear end of the hanging portion of the guideway 25. 1' As described above, it is composed of a sprocket 42 and a pulse motor 41 as a driving source, and is miniaturized so that it can be placed on the back side and one side of the back setting board 21.

The prize ball payout device 40 is a device that pays out a predetermined number of prize balls to the player when a ball hits the player area and receives prize balls from the winning ball detector 55 in the entered prize ball ejection path 22. Based on the signal, the sprockets 42 are sequentially rotated one by one by a drive command signal that is generated in a manner that reaches a predetermined number of sprockets.

When an abnormality in the flow of the reserve balls as described above is detected in the guideway 2517g, the control device 50 either stops the payout of the prize balls at that point, or stops the payout operation at 1, that is, after a predetermined number of balls are put out. After waiting for the prize balls to be paid out, the next payout will be stopped, and the control device 50 will turn on the alarm rank 58 (see Figure 12), such as an LED display element, to immediately identify the cause of the malfunction. In addition to ensuring that the prize balls are known and that prompt action is taken, it is also possible to reliably prevent the shortage of prize balls due to inaccurate ejection operations and the balls being caught in the tin rocket 42 due to incorrect ejection timing. It is designed to let you do so.

Below the prize ball dispensing device 40, on the back surface of the back setting board 21, there is a long type δ-shaped saucer storage section 36 that connects the second space A2 to the bottom of the prize ball dispensing device 40. This saucer storage part 36 is formed in a substantially S-shape so that the prize ball rectifies and flows downward, and also prevents the falling ball from colliding with the bell 37 provided below. It has a structure that can generate refreshing sounds.

Furthermore, the saucer storage section 36 is shown by the eighth section.

In the vicinity of the bell 37, there is a flow path converting part 38 that transforms the flow path by about 90 degrees to communicate with the saucer 9 provided on the front of the pachinko machine 1, and the prize ball flowing down is transferred to the saucer storage part. 3
6 second space A! From there, it passes through the first space A and the game board 8 to reach the surface of the game board. The surface of the game board is connected through a connection gutter 39 that is integrally attached to the saucer 9, as shown in FIG.

When a ball hits a prize during the game, the prize ball dispensing device 40 is driven to eject a predetermined number of prize balls into the saucer storage section 36, and the prize balls flow down and collide with the bell 37 for an exhilarating feeling. It is designed to generate a sound and flow out into the saucer 9 in a timely manner.

As shown in FIG. 5, the flow path conversion section 38 of the saucer storage section 36
A large auxiliary storage section 47 is connected to the auxiliary storage tray 12, which is formed to further extend the second space A2 diagonally downward to the left and communicates with the auxiliary saucer 12 provided at the lower front of the game board 8. When the bowl, saucer 9, and saucer storage section 36 are filled with prize balls, the prize balls automatically overflow and flow downward, thereby eliminating the need for the player's hands. It is possible to accumulate a large number of prize balls without being defeated, and it is now possible to deal with the currently popular pachinko machine called Lucky Seven.

In other words, a regulating piece 48 is provided in a protruding manner at the communication part between the flow path converting part 38 and the auxiliary storage part 47 in the second space A, and normally the ejected prize balls are prevented from getting over the board. As the saucer 9 becomes full, the prize ball accumulates toward the upstream side of the saucer storage section 36, and when the flow path converting section 3811 becomes full VC, the prize ball discharged δ automatically rides the regulation piece 48. It has a structure in which the liquid flows out into the auxiliary storage section 47 by crossing the gap.

Further, the auxiliary storage section 47 is filled with drumstick/coat! from the second space section A2. 1. Convert the flow path approximately 90 degrees to the front side, pass through the lower part of the game board 8, and further penetrate the front frame 4 to connect the auxiliary saucer 12.
It is connected to. As described above, the back side set board 21
A preliminary storage part U and a guideway δ are arranged above so as to form a second space A2 on the back side of the ball, and a hanging part of the guideway δ is provided continuously on the - side, and a prize ball payout is provided. device 40 , saucer storage section 36 . By providing the auxiliary storage section 47 and arranging the ball extraction passages 31 in parallel, the back mechanism panel can be further consolidated, and a relatively wide space C can be formed in the center. empty space C
As in the above embodiment, the first space A may be formed by making the back side setting board 21 entirely integrated, and the first space part A may be formed on the back of the back side set board 21, or the above-mentioned It is constructed so that the collecting plate 49 can be freely attached to the back of the back side cent plate 21 as shown by the two-dot chain line in FIG. Good too. In this way, as shown in the third garden, one part of the protruding enclosure of the variable tribute device 18 protruding to the rear of the back set board 21 can be formed into a separable set, [49], so it is sufficient to use great skill and force. Machining becomes easier.

FIG. 9 is an enlarged perspective view showing a configuration example of the electric prize ball dispensing device 40.

As shown in the figure, the terminal end of the guideway 25 is provided with a bend δn and two exit portions 25c and -2502 diagonally downward. A separation sprocket 42 is arranged to face the outlet portions 25cz and 25ez.
The L1 sprocket 42 is fixed to the rotating shaft of the pulse motor 41. A blocking plate 43 is fixed to the motor 41 at an appropriate distance from the sprocket 42.

Further, on the outer periphery of the tin rocket 42, there are, for example, six recesses 42 and six claws 4 in which penis balls can be held.
2 b is the formation name n. The exit portion 25° + + 25 at the end of the guideway 25 (!2 is configured such that one side faces the fourth part 42m of the sprocket 42 and the other side faces the claw part 42b. There is.

Then, the blocking plate B and the outlet part 25cl I 25e
A discharge gutter 44 connected to the upper end of the saucer storage part 36 is provided below the catch part 42b. The prize ball B that has come into contact with the recess 42B is locked to prevent it from flowing out.
The prize ball B' that has been engaged with the ball B' comes into contact with the blocking plate 43 and is clamped between it and the following prize ball B'. After 1 nyc, when the sprocket 42 rotates, the claw part 42bKyotsu-r separates from the lower discharge gutter. It is designed to flow down to 44 degrees.

FIG. 11 shows the ejecting action of the prize ball dispensing device 40. As shown in FIG. 11 (1), the ball B, which has first engaged with the recess 42□ of the sprocket 42, is moved by the claw as the sprocket rotates. When the ball B and the subsequent ball B come into contact with the claw part 42b1 as shown in FIG.
The ball B is engaged with the ball B and is sent downward by the claw portion 42b2 and separated. (-) When the ball B4 following the ball B comes into contact with the claw part 42b2, the ball B3 engages with the recess 42az and is separated by the claw part 42bt. Due to the separation action accompanying the rotation, the prize balls lined up in the outlet portions 25c1 and 25e are alternately discharged one by one into the collecting type spatula 44.

1, an L-shaped notch is formed in the blocking plate n1. This notch is provided with an ejected ball detector 45 having a plurality of sensors 45a to 45d, as shown in FIG. It's cool. The above sen? 45 out of 45a-45d
B and 45b detect whether or not there is a ball to be ejected next at the exit portions 25ci and 25°. 45C
and 45d are for checking whether the ball has been ejected or not, and both can be constructed using an optical sensor or a proximity switch.

In the prize ball payout device 40, when the winning detection signal output from the winning ball detector 55 is supplied to the control device 50, the motor 41 is activated by the drive signal outputted from the control device 50. Start draining. At this time, the control device 50 starts discharging after confirming that the spare balls are present at the exit of the taxiway 5 based on the detection signal from the discharged ball detector 45, and also receives a prize from the discharged ball detector 45. Upon receiving a discharge confirmation signal outputted from each ball (3n), the discharge state is detected, and upon determining that a predetermined number of prize balls has been reached, a discharge end signal is output to the prize ball dispensing device 40, and the rotation of the motor 41 is stopped. It is designed to be readable.

FIG. 12 shows a prize ball dispensing device 40 controlled by the control device 50.
FIG. 2 is a block diagram showing an example of a control system.

A generation formula n is generated from the winning ball detector 55 in response to each winning ball.
The winning detection signal (pulse) is supplied to a memory circuit 51, such as a counter, as a storage means, and is counted, thereby storing the number of winning balls. The control circuit 52 includes:
A detection signal from the ejected ball detector 45 in the prize ball dispensing device 40 is input, and the memory WE of the memory circuit 51 is 1.
1" or more, a drive start signal is output to drive the motor 41 of the prize ball dispensing device 40. Then, the motor 4
1 rotates and starts discharging the prize balls 11j, and a detection signal (pulse) is sent from the detector 45 to the control circuit 52 for each prize ball. The control circuit 52 counts this detection signal using an internal counter, for example, and as soon as the count value reaches a value set in advance in a setter of 8β.

When it is determined that a predetermined number of prize balls have been ejected, a motor drive stop signal is output, or the output of the motor drive signal is stopped to complete the ejection.

Further, when the detector 45 detects that the ball with the discharge name is not present at the exit section 25c, 25cffi at the end of the taxiway 5 due to soil clogging during discharge, etc., the detector 45 receives the output. Then, the control circuit 52 immediately stops the motor 41, holds the empty/reverse angle at that 1"ffi, and operates the motor 41 again when the prize ball enters the exit part 25°1e25e! When the remaining prize balls are ejected, the control circuit 52 sends a signal to the memory circuit 51 to decrement (reduce) the stored contents.

In addition, the signal from the ball shortage detector 56 is input to the control circuit 52, so that when there are no spare balls in the preliminary storage section 24 and a detection signal is sent to the control circuit 52, the motor 4L is activated. It is also possible to stop the drive and stop discharging the prize balls.

In this case, even if the ejecting operation of prize balls is stopped, the number of winning balls is retained in the memory circuit 51, and a new winning ball is detected within seven seconds, counted up, and stored. . Then, when the reserve balls have been replenished into the reserve storage section 24, it is preferable to start discharging the prize balls again in response to a control signal from the control circuit 52.

On the other hand, the control circuit 52 monitors the ball's flow abnormality based on the signal from the flow abnormality detector 57 installed in the middle of the taxiway, where dirt and foreign objects tend to enter and cause soil clogging. When an abnormal signal is received, the dispensing device 40 is stopped. The downflow abnormality detectors 57 are arranged in two rows in the guideway 25 and are provided for each row of spare balls flowing down.

In addition, the control device 50 consisting of the control circuit 52 and the memory circuit 51 detects this in the event of a power outage and maintains the information on the number of winning balls in the memory circuit 51 yen so that it will not be lost fL.
The battery is designed to increase τ bank up.

In the above-mentioned embodiment, by changing the set value of the setting device of the control circuit 52, it is possible to pay out any number of prize balls in each sea.

Moreover, a plurality of setters are provided in the control circuit 52 of the above embodiment to set different set values, and the winning area 1
A winning detector is installed every 5 to 18, and the type of winning is distinguished and the memory times INF! 51, it is also possible to change the number of prize balls to be thrown out depending on the type of winning.

Also, in place of the prize ball dispensing device 40 which separates and discharges the prize balls by driving the separation sprocket 42 with the motor 41 as in the embodiment, a solenoid and a flow prevention member are used. A non-destructive ball may be used so that the prize balls are separated and ejected one by one.

As explained above, the present invention employs a small, high-speed electric prize ball dispensing device that operates based on a winning detection signal generated by electrically detecting a batted ball that enters a winning area. The entire back mechanism panel was electronically controlled, eliminating the need for complex mechanical configurations, and the prize ball flow path and spare ball ejection path were shifted to one side of the back set panel. In addition, the winning ball ejection path and out ball ejection gutter are positioned downward.
Since they are integrated into the back set board, a wide empty space is formed in the center of the back of the game board, and it looks like it protrudes from the back of the game board to the rear of the back set board! By making it possible to install a large-scale variable winning device that utilizes a thermal drive source, the entertainment value of the pachinko game machine can be further enhanced.

In addition, the present invention provides a back set board that covers the entire bald area of the back of the game board with a laminated space structure of a first space part and a second space part,
The first space is provided with a shelf for collecting the winning balls that have passed through the game board, a winning ball discharge path, and an out ball discharge gutter, and a second space is provided that overlaps with the first space. The flow path for the prize ball is made up of a preliminary storage section, a guideway, and a saucer storage section, and a ball extraction path for the reserve balls is provided in parallel with this flow path. δn'''C It occupies less space, improves the fluidity of the balls, and provides rigidity in terms of drawing mechanics, which makes it possible to produce a large number of prize balls and prize balls in a short period of time. It will be possible to deal with the Lucky Seven-type pachinko game machines that can generate large numbers of winning balls and prize balls due to the adoption of large variable winning devices and the electrification of prize ball payout devices. The falling path of winning balls and prize balls has a single and more rigid structure compared to the conventional structure, which allows winning balls and prize balls to flow down smoothly, and improves the strength of each flowing path and the storage part for prize balls. This makes it possible to counteract the flow and accumulation of a large amount of balls.

Furthermore, this invention centralizes the exits of the winning ball ejection path, the out ball ejection gutter, and the spare ball ejection path at the lower end of the back setting board, so that each pile of soil can be centrally managed within the pachinko game parlor. The ball receiver that has been set δn is made to ensure that it flows into the socket on the side C of the box. Since it is possible to contact the company, it is possible to calculate the ball output rate and business results during business hours or after closing, and display or print them out at any time.This improves the accuracy of remote central control using computers. Sanru.

Moreover, the exits of the flow paths of each pile are functionally integrated,
The ball receiver is designed to face the box, so that once the balls have entered the box, the balls will not fly out, and even if the front frame that holds the game board is opened, the back mechanism board and ball receiver will not come out. does not interfere with the box at all and does not cause any trouble.
