Description

Description: FIELD OF THE INVENTION The present invention relates to a pachinko machine, and more particularly, to a pachinko machine having an improved safe ball pitching room for collecting safe balls provided behind a game board of a pachinko machine. .

[Prior art and problems] In general, a pachinko machine receives a pachinko ball (hit ball), which has become a safe ball through a winning ball receiver provided on a game board, in a ball shift room provided behind the game board, and aligns the ball therefrom. While sequentially sending out to the safe ball passage, the safe ball detection device that faces the safe ball passage ahead detects individual safe balls, and activates the prize ball device according to the number of safe balls, Although it is configured to release a prize ball to a player, there is a problem that if a large number of safe balls move in at one time through a prize ball receiver, the ball stays in the ball approaching room and the ball is clogged. In particular, when it becomes possible to win a large amount of prizes called a so-called "big hit", many safe balls often fly continuously at one time, and therefore, the safe balls stay on the bottom plate of the ball approaching room. The flow to the safe ball passage may be blocked, and the operation of the safe ball output device may be delayed.

The first cause of the ball clogging is that a large number of safe balls fly in at one time, but at the same time, the time required for the release of the prize ball takes a long time to operate the safe ball detecting device. The secondary causes are that the timing is adjusted over time and that a ball cutting device is interposed in the safe ball passage to sequentially send out the safe balls one by one. Since the means are elements that cannot be changed in the current pachinko machine, it is difficult to modify them to solve the problem.

[Object of the Invention] In view of such circumstances, the present invention improves a ball clogging state occurring in a ball-sucking room of a safe ball without affecting other unchangeable elements, and provides a safe ball. That is, it has been improved so that it can be smoothly guided to the passage.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention extends a ball-advancing room for receiving a safe ball to the rear, forms a storage space, and secures a stagnant place for safe balls. This is to eliminate clogging of balls caused by overlapping of balls.

As is well known, the ball moving room for the safe ball provided behind the game board of the pachinko machine may be provided directly on the back of the game board, or may be provided with a mechanism frame for fixing the game board as described in the following embodiments. Even when provided along the back surface, the front-rear width, that is, the depth width, is generally formed to a depth that substantially exceeds the diameter of one pachinko ball. This is because the safe spheres are arranged side by side to prevent bridging and cause clogging, but at the same time, it is structurally difficult to guide one ball at a time to the next safe ball passage. It depends.

The present invention enables the rearward expansion of the ball approaching chamber by combining an alignment gutter with a part of the bottom plate of the ball approaching chamber under such a premise, and enables smooth guidance without ball clogging. It was done.

The expansion of the ball draw room in the present invention extends rearward with reference to the bottom plate of the ball draw room, and at the same time, retreats the back plate to form an expanded storage space. The storage capacity of the safe ball is expanded so that it can be prepared for a large number of jumps at a time.

The present invention also provides an alignment in which the extended and widened bottom plate is formed on a V-shaped inclined surface so that the central portion is the lowest, and one of the inclined surfaces is bent back in the middle of the length. It is an object of the present invention to propose a pachinko machine in which a gutter is incorporated, and the safe spheres staying on the inclined bottom plate are guided to the alignment gutter to be aligned in a flow one by one and sent out to a safe sphere passage.

By the way, as described above, the depth width of the ball approaching chamber is conventionally selected to be slightly larger than the diameter of one pachinko ball from the plane 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 approaching chamber is somewhat larger than the diameter of one pachinko ball. On the other hand, regarding the incorporation of the alignment gutter into one inclined surface portion of the bottom plate formed in the V shape,
The length of the length is bent and formed in a folded shape to form a first alignment gutter section and a second alignment gutter section, and the first alignment gutter section has a bottom surface formed on the other inclined surface portion of the bottom plate. Preferably, the inclination direction is made continuous, while the second alignment gutter section is turned back so that the tip communicates with the safe ball passage.

The first alignment gutter section in the alignment gutter has a groove along the back side of the game board, and the width of this groove is gradually reduced from the base end side connected to the other inclined surface portion of the bottom plate, and also gradually. It is formed deeply and has a slope on the bottom surface, and the second alignment gutter section that follows is bent backward in a U-shape while continuing the slope of the bottom face so that it is parallel to the first alignment gutter section when viewed from above. Then, the width may be gradually reduced, and the leading end may be kneaded into the safe ball passage. Incidentally, the storage space in the present invention can be obtained by expanding the storage space by retreating to the appropriate height of the back plate with reference to the bottom plate of the ball close room, it is possible to form a storage space, this storage space If the winning ball receiver provided on the game board is formed so as to cover the entire area thereof, it is possible to receive the rear portion of the winning ball receiver, which is advantageous.
