An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a back view of a pachinko machine to which the present invention is applied. In the figure, 1 is a front frame of a pachinko machine, 2 is a game board detachably mounted on the back surface of the front frame 1, and 3 is a mechanism plate mounted on the back surface of the game board 2 so as to be freely opened and closed.
[0010]
A premium ball tank 4 is fixed to the upper part of the back surface of the mechanism plate 3. Below the prize ball tank 4, a tank rail 6 is provided for aligning the prize balls and guiding them to the prize ball dispensing device 5. Below the prize ball dispensing device 5, a prize ball discharge rod 7 for guiding the dispensed prize ball to a hitting ball supply tray (not shown) on the front surface of the front frame 1 and the hit ball supply dish are filled with the prize ball. At this time, an overflow rod 8 is formed for overflowing a surplus prize ball from the hitting ball supply tray to a ball storage tray (not shown). The prize ball discharge rod 7 and the overflow rod 8 are respectively provided with metal bells 9 and 10 so that the prize ball can collide. The bell 9 disposed in the prize ball discharge basket 7 generates a sound when the prize ball delivered from the prize ball dispensing device 5 collides, and notifies the player of the payout of the prize ball by the sound. In addition, the bell 10 disposed in the overflow bowl 8 generates a sound when a prize ball overflowing from the hitting ball supply tray collides, and the player tells the player that the prize ball has overflowed into the ball storage dish. It is to inform.
[0011]
FIG. 2 and FIG. 3 are perspective views of relevant parts for explaining the mounting structure of the bells 9 and 10 which are the features of this embodiment. The bell 9 and the bell 10 have the same mounting structure. Therefore, only the mounting structure of the bell 9 will be described, and the bell 10 will be omitted. On the bell mounting surface 7a of the prize ball discharge basket 7, a character-shaped pedestal portion 11 having a predetermined height is formed. A fitting convex portion 12 is formed on the pedestal portion 11.
[0012]
As shown in FIG. 4, the fitting convex portion 12 has a substantially T-shaped cross section and a cross shape with the pedestal portion 11. Further, hemispherical small protrusions 13 and 13 are formed on the upper surface of the pedestal portion 11 so as to be positioned above and below the fitting convex portion 12. On the other hand, a single-character-shaped opening 14 that can be fitted to the fitting convex portion 12 is provided at the bottom center portion of the bell 9.
[0013]
The lower surface of the fitting convex portion 12 is formed as tapered surfaces 15, 15, and the end portion of the fitting convex portion 12 is fitted with the opening 14 of the bell 9 into the fitting convex portion 12 as shown in FIG. Is formed so as to protrude slightly outward from the inner surface of the bottom surface of the bell 9 in a state where it is in contact with the small protrusions 13 and 13. Thus, by forming the lower surface of the fitting convex portion as the tapered surfaces 15, 15, the rotation operation of the bell 9 can be easily performed when the bell 9 described later is attached. Further, the distance L between the terminal ends of the tapered surfaces 15, 15 and the pedestal portion 11 is formed substantially equal to the thickness of the bell 9. Further, the small protrusions 13 and 13 are formed to have a size in contact with the inner peripheral edge of the opening 14 as shown in FIG.
[0014]
In the present invention having the above structure, in order to attach the bell 9 to the bell mounting surface 7a, first, as shown in FIGS. The bottom of the bell 9 is brought into contact with the small protrusions 13 and 13 by being fitted to the portion 12, and then the bell 9 is rotated 90 degrees and shown in FIGS. 5 (B), 7 (A) and 7 (B). Thus, the opening 14 can be achieved by fitting the small protrusions 13 and 13 into the fitting position. As a result, the rattle 9 is prevented from rattling in the front-rear direction by the pedestal portion 11 and the tapered surfaces 15 and 15 of the fitting convex portion 12, and the bellows 9 and the small protrusions 13 and 13 are fitted together. Is supported at a fixed position so that it does not move in the vertical direction and does not rotate.
[0015]
The pedestal portion 11 is for lifting the bell 9 from the bell mounting surface 7a to enhance the acoustic effect when the bell 9 is mounted, and is not necessarily required for mounting the bell 9. Therefore, when the base part 11 is not provided, the fitting convex part 12 and the small protrusions 13 and 13 may be formed directly on the bell mounting surface 7a. Moreover, the shape of the fitting convex part 12 and the opening 14 is not limited to the illustrated Example, For example, Y shape or a cross shape etc. may be sufficient seeing from the front.
[0016]
FIG. 8 shows another embodiment in which vertical surfaces 13a and 13a are formed on the small projections 13 and 13, and the edge of the opening 14 of the bell 9 is brought into contact with the vertical surfaces 13a and 13a. Is. In the case of this embodiment, the bell 9 is attached by rotating in the clockwise direction with the bell opening 14 fitted in the fitting convex portion 12. After the attachment, the edge of the opening 14 is perpendicular to the small protrusions 13 and 13 even if the acting ball is violently collided with the bell 9 and the counterclockwise rotation force acts on the bell 9. It abuts against the surfaces 13a and 13a to prevent its rotation. Accordingly, it is possible to prevent a situation in which the bell 9 is rotated by the collision of the prize ball and the attachment is removed. Further, as the shape of the small protrusions 13 and 13, for example, a wedge shape having a tapered surface as shown in FIG. 9 may be used.
[0017]
As described above, according to the present invention, the fitting convex portion and the small protrusion are formed on the bell mounting surface, and the opening provided in the center portion of the bottom surface of the bell is fitted into the fitting convex portion, and then the bell is turned. The bell is attached by moving and fitting the opening and the small protrusion. Accordingly, the bell can be easily attached by a one-touch operation without screwing, and the bell can be easily replaced.
