DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a ball-guiding member of a guide gutter for guiding a pachinko ball of a prize ball tank to a prize ball payout mechanism.

[0002]

2. Description of the Related Art As is well known, a conventional pachinko machine is installed with a guide gutter below a prize ball tank mounted on the back of a mechanism plate to guide a pachinko ball of the prize ball tank to a prize ball payout mechanism and win a prize. Each time a ball is generated, a certain number of pachinko balls are paid out to a prize ball discharge gutter. On the back side of the mechanism plate and above the guide gutter, the ball leveling member is pivotally pivoted to prevent the pachinko balls in the ball passage from stacking and flowing or falling out. Supported.

[0003] For example, if there is no ball leveling member, pachinko balls that flow in a stacked manner in the ball passage may flow down as they are, and the ball may be swollen at a bent gutter portion where the passage is narrowed by being connected to the guide gutter. Therefore, in order for the pachinko balls rectified by the ball leveling member to line up and flow down in a row, the ball leveling member must have enough weight to overcome the ball pressure of the pachinko ball on the front side, and usually the ball leveling member The members are weighted.

[0004]

However, in such a conventional pachinko machine, especially when the flow rate of the pachinko balls in the ball passage is large, the ball pressure of the pachinko balls flowing out of the prize ball tank and the ball leveling member are used. The situation where the weight is balanced and the ball is clogged on the near side of the ball leveling member,
Conversely, there was a serious problem that the original function of the ball leveling member could not be performed. Therefore, an object of the present invention is to solve such a problem, and an object of the present invention is to provide a ball leveling member that can reliably perform its original function.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a ball leveling device in which a pachinko ball of a prize ball tank is located above a guiding gutter for guiding the prize ball to a prize ball payout mechanism on the back of a mechanism plate. In a pachinko machine in which a member is pivotally supported so as to be freely swingable, a roller member having a horizontal axis provided at a lower portion of the ball leveling member and having a shaft hole having a relatively larger diameter than the shaft diameter is provided on the horizontal axis so that the roller member can freely move. It was made to support.

[0006]

[Function] Even if ball clogging is likely to occur on the front side of the ball leveling member, the roller member provided at the lower part of the ball leveling member moves up and down or back and forth due to the clearance between the shaft hole and the horizontal axis, and comes into contact therewith. The pachinko ball is moved to break the balance of the power of the entire pachinko ball and to smoothly flow down without causing clogging of the ball.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a guide gutter according to the present invention; FIG. 1 is a rear view of a pachinko machine to which the present invention is applied. In FIG. 1, reference numeral 1 denotes a game board mounting frame, 2 denotes a game board, and 3 denotes a mechanism plate rotatably mounted on the back of the game board 2. . The mechanism plate 3 has a plate portion 3a that forms a winning space at a predetermined distance from the back surface of the game board 2. A premium ball tank 4 is mounted on the upper rear surface of the mechanism plate 3, and a guiding gutter 6 having two ball passages 5a and 5b is mounted below the premium ball tank 4.

A prize ball payout mechanism 7 is mounted on one side of the rear surface of the mechanism plate 3.
Ball passages 5a and 5b communicate with each other. Below the prize ball payout mechanism 7, there is formed a prize ball discharge gutter 8 for guiding the paid-out pachinko balls to a hit ball supply tray (not shown) on the front of the pachinko machine. Reference numeral 9 denotes a ball drain gutter used to pull the pachinko balls in the premium ball tank 4.

Further, a winning ball discharge processing mechanism 10 for detecting pachinko balls flowing down the winning space one by one and discharging the pachinko balls to the outside of the machine is provided below the rear surface of the mechanism plate 3. Then, a predetermined number of pachinko balls are paid out to the prize ball discharge gutter 8 from the prize ball payout mechanism 7 by detecting the pachinko balls by the detector 11 in the winning ball discharge processing mechanism 10.

As shown in FIGS. 2 and 3, a support projection 12 is integrally formed on the rear surface of the mechanism plate 3 and above the guide gutter 6, as shown in FIGS. The support protrusion 12 pivotally supports a ball leveling member 13 to be described later in a swingable manner.
A cylindrical small-diameter shaft portion 12a is formed at the rear end, and a screw hole 12b is formed at the center thereof. The ball leveling member 13 has a thickness set so as to correspond to the width of the guide gutter 6, and a shaft hole 13 b is provided in an arm piece 13 a protruding from an upper portion thereof, and the shaft hole 13 b is formed in the small-diameter shaft portion 12 a. The screw 14 is fitted and screwed into the screw hole 12b to be attached.

Thus, two cuts 15, 15 are formed below the ball leveling member 13. Then, through holes 17 are formed in the support pieces 16, 16, 16 formed in the middle and both outer sides of these cuts 15, 15 in a line, and the through holes 17, 17, 17 are provided with horizontal axes. 18 to the ball passages 5a, 5
penetrate perpendicularly to b. Reference numerals 19a and 19b denote roller members, each of which has a thickness corresponding to the width of the ball passages 5a and 5b of the guide gutter 6, and whose center is compared with the shaft diameter of the horizontal shaft 18. Shaft holes 20, 20 having a relatively large diameter are provided therethrough.

Then, these roller members 19a, 19
b is inserted into the cuts 15, 15, and the horizontal shaft 18 is passed through the through holes 17, 17, 17 and the shaft holes 20, 20.
A retaining ring 2 is inserted into a locking groove 21 formed at the end of the horizontal shaft 18.
2, the roller member 19a is positioned in the ball passage 5a of the guide gutter 6, and the roller member 19b is positioned in the ball passage 5b of the guide gutter 6.

The ball leveling member of the guiding gutter according to the present invention has the above-described structure, and when the pachinko balls flowing down the ball passages 5a and 5b of the guiding gutter 6 are stacked as shown by the chain lines in FIGS. Even if the ball leveling member 13 is pushed by the pachinko ball and swings about the pivot of the arm piece 13a as a fulcrum, and the ball is kept balanced in that state, the ball leveling member 1 may be clogged.
Roller members 19a, 1 movably supported at the lower end of
The pachinko ball 9b is pushed by the pachinko ball and moves upward or forward and rotates at the same time, and presses the roller members 19a and 19b to stop and move the pachinko ball to maintain the balance, thereby balancing the force of the entire pachinko ball. Ball passage 5
Ball clogging does not occur on the front side of the ball leveling members 13a and 5b, and the rectification of the pachinko ball is always performed reliably.

[0014]

As described above, the ball leveling member of the guide gutter in the pachinko machine of the present invention has the roller member movably supported below the ball leveling member, so that it is stacked in the ball passage of the guide gutter. The force balance between the flowing down pachinko ball and the ball leveling member is broken, and the ball is not clogged on the front side of the roller member, and the rectification of the pachinko ball can be reliably performed. Ball swelling in the bent gutter at the bottom of the gutter is also prevented.
