Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a pachinko machine, and more particularly to a pachinko machine with an improved ball collection chamber for safe balls provided behind the game board of the pachinko machine. .

[Prior art and problems] In general, pachinko machines pass safe pachinko balls (hit balls) through a winning ball receiver provided on the game board into a ball collection chamber provided behind the game board, and from there The balls are lined up and sent out to the safe ball path one by one.
Beyond that, a safe ball detection device facing the safe ball path detects each safe ball, and a prize ball device is operated according to the number of safe balls to discharge the prize balls to the player. However, there was a problem that if a large number of safe balls were transferred through the winning ball receiver at the same time, they would accumulate in the one-ball gathering room, causing a ball jam. In particular, when a large amount of winnings is possible, which is called a "big hit," a large number of safe balls often fly into the ball in succession, and as a result, they accumulate on the bottom plate of the ball collection chamber. The flow to the safe ball passage may become clogged and the operation of the safe ball detection device may be delayed.

The first cause of this ball jam is that a large number of safe balls fly in at once, but at the same time, it takes time to release the prize balls, and it also takes time to activate the safe ball detection device. A secondary cause is that the timing has to be adjusted over time and that a ball cutting device is interposed in the safe ball path to send out the safe balls one by one, but these Since the means are immutable elements in current pachinko machines, it is difficult to solve the problem by modifying them.

[Object of the Invention] In view of the above-mentioned circumstances, the present invention improves the ball clogging condition that occurs inside the ball collection chamber of a safe ball without affecting other unchangeable factors, This is because improvements have been made to allow smooth guidance to the passageway.

[Means for Solving the Problems] In order to solve the above problems, the present invention extends the ball collection chamber for receiving the safe balls rearward to form a storage space to secure a place where the safe balls accumulate. This eliminates the problem of ball clogging caused by overlapping balls.

As is well known, the safe ball collection chamber provided behind the game board of a pachinko machine can be installed directly on the back of the game board, or it can be installed directly on the back of the game board, or as explained in the vk-described embodiment, a mechanism frame for fixing the game board is used. Even when the pachinko ball is provided along the back surface of the pachinko ball, its front-to-back width, that is, the depth thereof, is usually formed to a depth that exceeds the diameter of one pachinko ball.

This is to prevent the safe balls from lining up one after the other, causing a bridging phenomenon and causing ball clogging, but at the same time, it also makes it structurally difficult to align and guide each ball to the next safe ball path. It depends.

Under such a premise, the present invention makes it possible to expand the ball-closing chamber rearward by combining an alignment gutter with a part of the bottom plate of the ball-closing chamber, and also enables smooth guidance without ball clogging. That's what I did.

Expansion of the ball collection chamber in the present invention is performed by extending the bottom plate of the ball collection chamber rearward based on the base plate, and at the same time, retreating the back plate to form an expanded storage space. This is to expand the storage capacity of safe balls so that it can be prepared for a large number of balls flying in at once.

Further, in the second aspect of the present invention, the extended and widened bottom plate is formed into a V-shaped inclined surface so that the center part is the lowest, and one inclined surface is bent in the middle of the length. To propose a pachinko machine which incorporates a gutter and guides the safe balls accumulated on the inclined bottom plate to the alignment gutter, aligns them one by one in a flow, and sends them out to a safe ball passage.

By the way, as mentioned above, in the past, the depth width of the ball collection chamber has been selected to be somewhat larger than the diameter of one pachinko ball from the viewpoint of guiding the alignment of the balls. For the same reason, it is appropriate that the extension width of the bottom plate of the ball holding room be somewhat wider than the diameter of one pachinko ball. On the other hand, the alignment gutter is incorporated into one inclined surface portion of the V-shaped bottom plate,
A first alignment gutter section and a second alignment gutter section are formed by bending the middle of the length to form a folded shape, and the first alignment gutter section has its bottom surface connected to the other inclined surface portion of the bottom plate. It is preferable that the second alignment gutter section is folded back so that its tip communicates with the safe ball passage.

The first alignment gutter section of the alignment gutter has a groove along the back side of the game board. The second alignment gutter section is formed deeply and has a slope on the bottom surface, and the second alignment gutter section that follows this continues the slope of the bottom surface and is pressurized backward in a U-shape so that it is parallel to the first alignment gutter section when viewed from above. What is necessary is to fold it back like this and gradually narrow the width so that its tip communicates with the safe ball passage.

Note that the storage space in the present invention can be expanded and formed by retracting the back plate to an appropriate height based on the bottom plate of the ball-closing chamber. If the winning ball receivers provided on the game board are formed over an enclosure that can entirely surround them, the rear retaining portions of these winning ball receivers can be inserted into the receiver, which can be advantageously implemented.

Hereinafter, embodiments illustrating the present invention will be described in more detail and its features will be clarified.

As has been widely put into practical use, the above-mentioned window is designed so that the rear part of the winning ball receiver (not shown) provided on the game board surface or the gutter 11 etc. that connects the rear parts of the winning ball receivers are exposed behind the board part 2a. A ball-closing room 9 is formed to cover this window from behind.

In the ball gathering chamber 9, a main body part 9a is formed based on the base plate 5, which is disposed opposite to the back surface of the plate part 2a at a distance exceeding the diameter of one pachinko ball, and a frame body 8 is formed behind the base plate 5. An expanded storage space 9b is formed by the surrounding area, and a single space, that is, a ball-closing chamber, is formed by combining the two. The frame body 8 forming the storage space 9b constitutes an upper surface portion, left and right side portions, and the rearward protrusion width is the same as the distance between the base plate 5 and the plate portion 2a. The length exceeds the diameter of one ball, and a back plate 12 is attached to the rear edge to close the back, and the bottom is closed by a bottom plate 13 that is common to the main body part 9a to form the ball holding chamber 9 as an independent space. do.

The bottom plate 13 is formed into a substantially V-shape with the center at the lowest position, and is sloped downward from the left and right direction toward the center.One half of the bottom plate has an inclined surface part as an alignment gutter 14. It has a structure in which it communicates with a safe ball passage 15 provided below the ball collection chamber 9 via an alignment gutter.

The alignment gutter 14 cooperates with the slope of the bottom plate 13 to align the safe balls that irregularly enter the ball collection chamber 9 through the winning ball receiver of the game board 3, and guide them one by one into the safe ball passage 15. , the first part is provided in a folded manner as shown in the figure.
It is composed of an alignment gutter section 14a and a second alignment gutter section 14b. The first alignment gutter section has the role of the first step of arranging the safe balls that fall onto the bottom plate 13 and accumulate in a line, and is located at the lower end of the other inclined surface portion 13a (center part of the bottom plate 13). One end facing the opening is used as a receiving opening 1B, and a groove 17 is formed which is aligned with the depth and width of the bottom plate 13, and from which the depth of the bottom is gradually deepened and the opening width is gradually narrowed.

The groove 17 is provided along the edge side of the bottom plate 13 of the ball-closing chamber 9, and an inclined plate 18 is provided between it and the back plate 12 formed by the gap between the opening widths to close the gap. This inclined plate 18 substantially constitutes one half of the inclined surface part of the bottom plate 13, and the safe balls falling and staying here are held in the groove 1.
It will fall to 7. In addition, the first aligned gutter section 1
The bottom surface of the groove 4a is formed to have a downward slope along the extension line in the slope direction of the other inclined surface portion 13a, and the tip thereof is bent back toward the rear and communicates with the second aligned gutter section 14b.

The second alignment gutter section is located below the inclined plate 18, covers the upper surface thereof, and is provided parallel to the first alignment gutter section 14a when viewed from above. This alignment gutter section is a section for arranging the safe balls in rows and at the same time aligning the overlapping balls one by one with the bottom surface. is formed to have a downward slope following the slope of the first aligned gutter section. The tip outlet 20 is bent into an S-shape and is located directly below the receiving port 1B of the first alignment gutter section, and the safe ball passage 1 is attached along the back surface of the plate part 2a of the mechanism frame 2.

(See FIG. 7), and this alignment gutter is formed independently so that it can be removed when the back plate of the ball collection chamber is opened, as will be described later.

In the figure, 27 is a ball cutting device facing the safe ball path 15, and 28 is a safe ball detecting device that swings in response to a safe ball falling through the safe ball path and detects its passage. The ball cutting device @27 swings up and down about the support shaft 29 by the weight of the safe balls received on the forked portion 27a, and sends out the safe balls one by one to the vertical passage t5a. The safe ball rides on the swinging tip of the safe ball detection device 28 waiting here, pushes it down with the weight of the ball using the support shaft 30 as a fulcrum, and when it reaches its lower end, it rolls out from the tip and is guided to the discharge path 31. .

The safe ball detection device 128 detects the connection rod 32 through the above-mentioned swinging motion.
is pushed up, and through this action, the cover 33 of the prize ball storage case of the prize ball device IO is opened, and the prize balls are released into the prize ball discharge gutter 34. The released prize ball hits the lint 35 facing into the gutter 34, and is guided from the discharge port 36 provided below to the prize ball ff1 (not shown) arranged in front of the door frame 1.

In this embodiment, the safe ball detection device 28 including the safe ball passage 15 and the cover 33 are included! 110, and a part of the guide gutter 7 that guides the prize balls to the prize ball device, the prize ball discharge gutter 34, etc. are all housed in the case body 37 in the shape of an inverted letter.
This case body 37 is attached via a hinge 38 to the back surface of the plate portion 2a of the mechanism frame 2 so as to be freely openable and closable. Then, the frame body 8 surrounding the storage space 9b and the back plate 12 that closes off the back of the ball-closing chamber 9 are attached along the free edge of the case body 37, and when the case body is opened, the ball-closing chamber This allows the back of 9 to be opened.

In the figure, numeral 38 is a frame member fixed vertically along the other side edge of the mechanism frame 2 so as to face the case body 37, and a part of the frame 8 is provided along this frame member. 40 is the back plate 12
It is a box-shaped case that closes a window 41 opened in the center of the game board, and covers the winning m fil 42 that protrudes from the back of the game board.Furthermore, 43 is a release path for releasing out balls from an out port 44 of the game board. .

The present invention is constructed as described above, and the winning balls on the game board and the batted balls that fly into the winning device and become safe balls are pulled out to the back of the game board and transferred to the safe ball collection room 9. However, each ball falls onto the bottom plate 13 and is guided to the receiving port 18 of the alignment gutter 14 according to its slope, but in the transfer of this safe ball, the winning ball receiver or the landing conditions of the winning device are In this invention, when a large number of prizes are won at once, a storage space 9b is created behind the main body 9a of the ball collection chamber 9.
Since the safety balls are added and the depth and width of the bottom plate 13 are expanded, the safe balls are prevented from overlapping each other and are housed in a dispersed state on the bottom plate. And 2. The safe balls that have fallen onto the bottom plate 13 are guided to the receiving port 16 of the wide-open alignment gutter 14 and are transferred to the first alignment gutter section 1.
4a, the overlapping safe balls while moving through the groove 17 are finally leveled into a line and are transferred to the next second aligned gutter section 1.
4b into the groove 18.

These two alignment gutter sections are formed in a folded shape to ensure the length necessary for aligning the safe balls within a limited space, and the overlapping state of the balls is maintained within the gentle slope of the bottom surface. will be resolved. The safe balls that have passed through the alignment gutter 14 enter the safe ball passage 15 as described above, activate the safe ball detection device 128, and activate the prize ball device 1G.

Incidentally, in the above embodiment, the storage space 9b of the one-ball gathering chamber 9 is prepared especially to expand the depth and width of the bottom plate 13, and for this reason, it is formed near the bottom plate so that the safe ball can be stored. This works effectively to avoid ball clogging caused by accumulation, but if a large space is provided above as shown in the figure, it becomes possible to accommodate the protrusion of the S part of the winning ball holder. .

[Effects of the Invention 1] As described above in detail based on the embodiments, the present invention provides a ball collection chamber for receiving safe balls with a depth and width as implemented in conventional pachinko machines, and a storage space at the rear of the ball collection chamber. Since the safety balls that have fallen onto the bottom plate have been expanded and enlarged, and the bottom plate has been widened backwards, there is no way that the safe balls that have fallen onto the bottom plate will accumulate on top of each other, and each one will come into direct contact with the bottom plate. Since the balls are guided by the slope, they can be easily aligned, and ball clogging in the ball collection chamber can therefore be effectively avoided. The first plate is placed on one half of this bottom plate. Since the second alignment gutter section is provided in a folded manner to ensure a sufficient length for alignment, it is possible to reliably align the safe balls in a single line. It is possible to send out one by one.

As described above, the present invention eliminates ball clogging in the ball collection chamber and allows safe balls to be delivered one by one to the safe ball path reliably and smoothly, thereby preventing unexpected stoppages in the game board caused by ball clogging. Needless to say, it is possible to effectively avoid problems such as problems and breakdowns.
