On the other hand, the prize ball release path 17 is equipped with a bell 24 at its lower end, and its opening faces the communication window provided in the base plate 11.
Furthermore, there is an overflow ball passage section, and on the other hand, this prize ball release path 1
A ball extraction gutter 18 arranged in parallel with 7 is formed as an independent passage so as to reach the lower end of the frame.

n is a safe ball passage provided on the back side of the board 11 in the lower half of the mechanism frame 9, that is, inside the chamber 12; 2 is a controller that allows successive safe balls to pass one by one; 4 is a safe ball detector that detects safe balls flowing down the safe ball passage 27, and the blade is an interlocking rod that transmits the operation of the safe ball detector to the operating member of the prize ball device.

The safe ball passage n is opened and communicated with the sloped ball gathering frame 31 formed by the lower upper edge of the case 7 and the lower upper edge of the mechanism frame, and the controller recommends turning the upper part of this safe ball passage. It is installed facing the part.

The control path is equipped with a weight at the rear end (on the right in FIG. 2), and the front end is always urged upward with the pivot 32 as the fulcrum, waiting for the safe ball to flow in, and the safe ball is placed in the concave receiving portion 33. When the ball enters the ball, it receives its weight, shifts to a forward leaning position, and sends it out into the path formed in a loose arc shape.At this time, the safe ball that flies in consecutively is blocked by its stopper tone, and at the same time, the two
The safe ball detector 4 is designed to prevent the balls from flowing into the above-mentioned path.The safe ball detector 4 has its rear end supported on a shaft embedded in the substrate 11, and its tip faces the arc-shaped safe ball path. When the safe ball flows through the controller array, the ball is received at the tip and swings around the shaft 35f, a fulcrum, to detect the safe ball.The swinging rear end is provided with an interlocking rod. 30t-connected.

The interlocking rod (9) is made of a heavy metal rod, and its upper end is connected to the operating member n of the prize ball device, and it is always activated, that is, when no safe ball passes through. The weight of the interlocking rod flips up the tip of the detector 4 to prepare for the passage of the safe ball, and the actuating member 23 is lowered using its spindle as a fulcrum to insert the front Hd into the notch 37 formed at its lower edge. A pin (not shown) installed in the case cover 21 of the prize ball case is hooked and fixed to restrain the case cover 21 in a closed state.

In the figure, A is a detection plate that detects when there is a shortage of prize balls in the ball catching guideway 14 and a predetermined number of prize balls cannot be supplied to the prize ball case 15, and 39 is a detection plate that detects when there is a shortage of prize balls. When detected, 1.J is a swinging lever that restrains the operation of the interlocking lever; 4;
0 is a connecting rod that connects the swinging rod and the actuating member 23.

The space between the detection plates is formed in an L-shape, and a support shaft 41 installed in the base plate 11 is provided so as to be able to swing freely around the fulcrum, and the detection plate 38a is always connected to the guideway 14. If there is a prize ball in this, it will be pushed up by its diameter, and if it is missing, it will fall down into the guideway 14 due to its own weight, and it will fall under the pin 42 provided at one end of the stopper piece 38btfflI moving rod 39. The plan was to have it submerge under the ground to prevent it from descending. And, the swinging rod 39 is the support shaft 4 installed in the room 121ltlK.

As the actuating member oscillates about its supporting shaft due to the vertical movement of
When the ball drops and the supply of prize balls is insufficient, the stopper piece 38b is hidden under the pin 42 to prevent its swinging movement, thereby restraining the operation of the operating member and preventing the prize ball from being supplied. Stop emission. Therefore, due to the function of this device, when insufficient prize balls are stored in the prize ball case, the prize balls will not be ejected as unspecified prize balls.

Now, the mechanism frame 9 that houses the above-mentioned winning ball device, safe ball detection device, interlocking device, etc. has a pivot shaft member provided above and below one side edge, and a bearing 45 provided above and below the right side edge of the base frame plate 1. It is pivotally mounted to open and close freely by being supported by the metal fittings 46 and 47, and is normally closed in contact with the back surface of the base frame plate using this pivoting portion as a fulcrum. By this closing, the cover 6 of the ball supply gutter 5 and the cover 6 of the ball supply gutter 5 described above, in cooperation with the Kusuf, surround the entire circumference of the window 3 that is opened in the base frame board, and are fitted from the front side of the base frame board with this surrounding. A safe ball collection chamber 49 is formed by the game board IO1 and a back cover 48, which will be described later.

The back cover 48 is formed to match the size of the safe ball collection chamber 49 surrounded by the cover 6, the coupe and the mechanism frame 9, and here a protrusion is formed along the inner edge of the base plate 11 of the mechanism frame 9. By screwing one side edge to the mounting single blade to be installed, it is fixed to the mechanism frame 9, and the back side of the safe ball gathering chamber 49 can be opened and closed as the mechanism frame is opened and closed. .

In the figure, reference numeral 51 denotes a stop plate that restrains the free end of the opening/closing back cover in a fully closed state, and 52 is a control electric circuit box for operating the winning device attached to this stop plate.

The stop plate 51 is rotatably attached to a pivot portion 53 provided on the inner side surface of the coupe, and when the mechanism frame is closed, the free edge of the back cover 48 projects from the inner side surface of the coupe. When the receiver comes into contact with the piece 54, it can restrain the back cover by overlapping the pivot portion 53tl--the fulcrum. The electric circuit box 52 is removably fixed to the stopper plate 51 with screws, and when the winning device installed on the game board 1o changes due to the replacement of the game board 1o, the circuit corresponding to this winning device can be installed. Comes with a box for easy replacement.

On the other hand, the reference numeral 55 in the figure is a locking device which, together with the stop plate 51, restrains the opening of the mechanism frame 9t when the mechanism frame 9t is closed.

This locking device 55 is shown in enlarged form in FIGS. 7 to 9.
Upper outlet shaft 56 of the ball feeder 5 fixed to the base frame plate 1
The stopper member 58 is comprised of a rotary lock plate 57 which is rotatably supported by a rotary lock plate 57, and a stopper member 58 which moves up and down in conjunction with the rotation of the lock plate to open and close the outlet of the ball feeder 5. The rotation lock plate 57 has an oblique long hole 59t formed in a substantially fan-shaped plate portion, and a boss 60f of the stopper member path is connected to this long hole by sliding it.When locking, the handle 61 is A part of the lock plate 57 is made to stand vertically and protrude in front of the ball feeder 5, and is engaged with a retaining portion 62 provided at the upper free end of the mechanism frame 9 which is brought into contact with the tip of the feed gutter. This is to restrict opening of this.

FIGS. 7 and 8 show this restrained state. At this time, the stopper member μs rises and pulls up its lower end from the outlet of the ball feeder 5, and the ball catching guide path 1 of the mechanism frame 9 faces this outlet.
It is designed to communicate with 4.

In this state, when the handle 61 is next tilted to the right, the protruding portion of the lock plate 57 retreats from the locking portion 62 of the mechanism frame, releasing the lock and freeing the mechanism frame. As the lock plate 57 rotates, the elongated hole 59 pushes down the boss 60 that slides into it, so the stopper member path descends, blocking the ball feeder 5t and stopping the flow of the reserved balls for prize balls. 0 That is, the locking device 55 equipped with the stopper member 58 is
The mechanism frame 9 is always restrained in a closed state, and the ball feeding path 14 is communicated with the ball feeding device 5 fixed to the temporary back surface of the base frame, so that the ball catching guide path 14 can be set so as to be able to feed the stored balls to the prize ball device. When the mechanism frame is released from the back side of the base frame plate 1, the lock plate 570 rotates to release from the retaining part 62, and at the same time, the stopper member 58 is lowered and the ball feeder 5 is released. This will prevent the balls from flowing out from this gutter, which opens when the mechanism frame is opened.

In addition, in the figure, 63 is a prize ball discharge path 17 in a prize ball tray attached to the front of the base frame board 1, a discharge port opened in the base frame board for sending out prize balls released through the window 25, and 64 is a discharge port opened in the base frame board 10. A through hole is temporarily opened in the base frame to communicate with the out ball opening of the mechanism frame, and this through hole communicates with an out ball passage 65 provided vertically in the lower part of the mechanism frame.

Now, in the pachinko machine configured as described above, the game board 10 is attached to the front surface of the base frame board 1, and the back surface of the game board 10 faces the window 3. When in use, the mechanism frame 9, which is attached to the back of the base frame plate so that it can be opened and closed via a pivot joint, is always closed in contact with the μ-tuck device 55t. are engaged and restrained in a closed state so that the catching ball guiding path 14 and the ball supplying ball gutter 5t are made to pass continuously, and the stored prize balls from the storage tank 4 are guided through the guiding path 14 to the prize ball case 15, The safe ball passage 27 is made to face the safe ball approach room 49. At the same time, in the embodiment described above, the back cover 48, which is integrally screwed to the mechanism frame 9, is placed over the back of the safe ball-closing chamber 49 to make this chamber like a closed room.
A receiver whose free edge is provided on the cover 7 abuts against the piece 54;
Place the stopper plate 51 over the overlapping pieces, and insert the receiver between the pieces.
Bind the back cover.

In this way, the pachinko machine of the present invention transfers the balls stored in the storage tank 4 to the ball feeder 5. The balls are guided through the entire guideway 14 to the prize ball case 15, where a predetermined number of balls are stored and prepared for release.

As the game progresses, the safe ball flies into the safe ball area,
When the ball passes through the ball collection frame 31 and enters the safe ball passage a,
First, the controller 28 is activated, and then the safe ball detector 29 facing the passage is pushed down and the interlocking rod 30 is pushed up, and the actuating member 23t supported by the support shaft 36 is swung, and the notch formed in it is The pin of the case lid 21 that is engaged with the hole 37 is removed, the case lid is opened, and the prize balls stored in the prize ball case 15 are released. The entire discharge slot 63 is sent out to the prize ball tray, and at the same time, the upper part of the prize ball couper is closed with an inflow control piece linked to the above-mentioned operating member, and only a predetermined number of stored prize balls are released. .

The ejection operation of the Kono prize ball is performed by raising the interlocking rod as the detector pressed down by the safe ball returns to its original state, and the actuating member also returns to its original state. The ball is now complete and ready for the next safe ball to fly in.

The pachinko machine of the present invention is constructed as described above, and if a failure occurs in the safe ball detection device, prize ball device, etc., which are frequently activated during play, the lock device &55. By disengaging the stop plate 51, the mechanism frame 9 housing these devices is opened from the back of the base frame plate 1 using the pivoting portion as a fulcrum, and the chamber 12 incorporating the operating mechanism portion is opened to the front. Since it can be exposed, repairs and inspections can be carried out extremely quickly.

In particular, the safe ball detection device and the prize ball device must be sealed in the assembled state to prevent tampering.
At the same time, since the ball is precisely made to react sensitively to the ball, malfunctions such as ball clogging are likely to occur, and there was a need for an easy release mechanism. Since it can be immediately opened from a sealed state, it is extremely advantageous not only in repair work but also in maintenance and inspection work.

The mechanism frame of C is a bearing fitting 46 provided on the base frame plate.
, 47 by inserting the pivot shafts 44 and 45'i provided in the mechanism frame, so if a malfunction occurs in the entire built-in device, the entire mechanism frame can be easily removed. It is also possible to exchange it for a new one.

By the way, the mechanism frame 9 in the present invention is made of a single substrate 11 made of plastic as described in the embodiments.
In the room 13 on one side of the center, there are a prize ball guide path 14, a prize ball release path 17, a ball ejecting gutter 18, an overflow ball path, an out ball release path 65, etc. related to the sex prize ball device, and the other side. 9m1 on the side
2 is integrally formed with a safe ball passage 4, etc., and in contrast to these fixedly provided parts, there are movable parts such as a prize ball case 15, a case lid 21. The safe sphere detection unit can be assembled by pivoting to pins, spindles, etc. that are implanted at predetermined positions in advance, so it can be assembled with extremely high precision. Moreover, since the fixed parts are integrally molded with the frame body of the mechanism frame, and the mounting positions of the movable parts are also set in advance, assembly and manufacturing can be carried out extremely quickly.

In addition, the pachinko machine of the present invention has two chambers 12 and 13 on both sides of the mechanism frame 9 with the substrate 11 at the center, and one chamber 12 has a safe ball passage and a safe ball detection system such as a safe ball detector. equipment and an interlocking device such as an interlocking rod that transmits the operation of this device to the prize ball device, and the other room 13
By equipping the system with prize ball system devices such as a prize ball case 15 and a prize ball ejection path 17, we succeeded in narrowing the width of the mechanism frame and making it a vertically elongated frame. 3, it can be attached in contact with one side of the back surface of the base frame board 1 narrowed by the opening of the base frame board 1. Therefore, by attaching the coughing mechanism frame, the ball collection room formed behind the window 3 is not blocked, so the game board 1
Even if a winning device with a deeper depth than that of 0 is installed, this mechanism frame does not obstruct it and it is possible to select various winning devices.

On the other hand, in the pachinko machine of the present invention, since one side edge of the back cover 48 that closes the back side of the ball-closing chamber is fixed to the mechanism frame, the ball-closing chamber 49 can be opened when the mechanism frame is opened.
This is advantageous for maintenance and inspection of the winning device installed on the game board.
