〔Example〕

As shown in FIG. 1, a pachinko machine using the present invention is composed of a glass frame 1, a game board 2, and a base frame 3. The glass frame 1 is an integrally molded synthetic resin product, and is provided with two rows of protrusions 5a and 5b for holding the front glass 4 inserted from above. These protrusions 5a, 5b are arranged so as not to overlap each other when viewed from the front of the glass frame 1 in consideration of moldability.

A circular opening 6 is formed approximately in the center of the glass frame 1. A steel rail 7 is fixed to the inner periphery of this opening 6. This rail 7 is attached to the base frame 3
The pachinko ball is connected to a guide rail 8 of the pachinko machine provided on the base frame 3, and guides the pachinko ball shot out from the launcher 10 provided on the base frame 3 to the board surface 2a of the game board 2. Furthermore, a prize ball outlet 11 is formed at the lower front of the glass frame 1, and an upper tray 12 is formed.
A mounting portion 14 is provided for fixing. Note that a gutter 15 is inserted and fixed in the discharge port 11. Further, a ball feeding section 16 is integrated into the upper tray 12, and the pachinko balls stored in the upper tray 12 are fed into the introduction port 17 one by one.

As is well known, the game board 2 is equipped with safe holes, tulips, atats, winning ball devices, obstacle nails, windmills, etc. At the bottom, there is an out hole that penetrates from the front to the back of the game board 2. Hole 1
8 is formed. Further, a rail 20 is fixed to the board surface 2a. The lower edge of this rail 20 is connected to the terminal end of the rail 7 fixed to the glass frame 1. The pachinko balls ejected from the ejecting device 10 provided on the base frame 3 are guided by the ejecting guide rails 8 and rails 7 and flow down after reaching above the board surface 2a.

During this process of flowing down, the pachinko balls that hit the safe hole, the ticket, etc. are collected all at once by the safe ball receiver 22 attached to the back of the game board 2, as shown in FIG. It is discharged from 23. A well-known safe ball detector 24 made of a photo sensor or the like is installed in the middle of this discharge path 23, and the number of safe balls is counted. On the other hand, out balls that do not land in either the safe hole or the tulip are collected in the out hole 18 and then discharged from the out ball discharge path 25. In addition, instead of fixing the safe ball receiver 22 and the out ball discharge path 25 to the back surface of the game board 2, they may be arranged in a conventionally known mechanical frame that is pressed against the back surface of the game board 2.

A game board 2 is mounted on the base frame 3, which is a molded product of synthetic resin.
can be installed. For this purpose, an opening 28 for receiving the protrusion 27 on the back side of the game board 2 and a protrusion 29 that fits into a positioning hole (not shown) of the game board 2 to determine the mounting position of the game board 2 are formed. ing.

The base frame 3 is formed with an opening 30 for discharging the prize ball to the upper tray 12, a guide gutter 31 thereof, and an opening 35 for discharging the prize ball to the lower tray 34. Further, as shown in FIG. 3, when the upper tray 12 is full of prize balls, there is a guide plate 37, an opening 38, and a gutter 39 for guiding the prize balls to the lower tray 34.
It is also integrally molded. And in the gutter 39,
For example, since the cover 40 is attached with screws, the prize ball that has flown down along the guide plate 37 passes through the opening 38 and wraps around the back side of the base frame 3, and then passes through the gutter 39 and the cover 40. It is discharged to the lower tray 34.

As shown in FIG. 2, partition walls 42 and 43 for forming a safe ball socket and an out ball socket are integrally formed on the back surface of the base frame 3. Since a safe ball passage 45 and an out ball passage 46 are fixed to the partition walls 42 and 43, respectively, the pachinko balls discharged from the safe ball discharge passage 23 and the out ball discharge passage 25 are routed through the respective passages 4.
5 and 46 are discharged separately from the lower discharge ports.

On the back side of the base frame 3, a pair of troughs 48 for defining a prize ball discharge path and a pair of troughs 49 for defining a ball removal path are further integrally provided.
These gutters 48 and 49 are formed in a band shape along the back surface of the base frame 3, and these gutters 48 and 49 are covered with a cover 50.
Each passage is defined by covering it with A tank 52 for storing prize balls and a guide passage 53 for guiding the pachinko balls from the tank 52 to the gutter 48 or the gutter 49 are attached to the back side of the base frame 3. In the middle of the guide path 53, there is a ball extraction part 55 which is closed in normal use, and a counter that counts and sends out a certain number of pachinko balls when the safe ball detector 24 detects one safe ball. A sending section 56 is attached. Then, each time a safe ball occurs in the process of playing a pachinko game, the counting sending unit 56 sends a certain number of prize balls to the gutter 4.
8 and a cover 50.

The prize ball sent out to the prize ball ejection path is bell 58.
After colliding with and making a sound, it reaches the opening 30. If there is enough space in the upper tray 12, the prize ball will be dispensed to the upper tray 12 through the gutter 15 attached to the glass frame 1 and the discharge port 11. guide plate 3 before reaching
Falling to 7. The prize balls dropped onto the guide plate 37 are discharged into the lower tray 34 through the opening 35 according to the route already described.

When collecting all the pachinko balls stored in the tank 52, such as when closing business at a pachinko parlor, the ball extractor 5 is operated in conjunction with a well-known ball extracting operation.
5 is released. Then, the pachinko balls in the tank 52 pass through the guide passage 53 and fall from the ball extraction part 55. Then, it flows down following the ball removal passage defined by the gutter 49 and the cover 50.
The pachinko balls flown down by the ball extraction are discharged from the discharge port below through the out ball passage 46, like the out balls. Of course, since the safe ball passage 45 and the out ball passage 46 each have independent passages, the pachinko balls passing through these passages 45 and 46 are not mixed. In addition,
The shaft of a firing operation handle (not shown) for operating the firing device 10 is inserted into the opening 60 formed below the base frame 3 . Further, a metal fitting for fixing the game board 2 to the base frame 3 is attached to the opening 62 of the base frame 3.

In order to support the glass frame 1 on the base frame 3 so that it can be opened and closed, a metal shaft 63 fixed to the glass frame 1 is fitted into the base frame 3, and then a metal fitting 64 is used to prevent it from coming off. A well-known locking mechanism is attached to the glass frame 1 and the base frame 3, and when the glass frame 1 is closed, a locking piece passes through a slit 65 in the base frame 3 and is locked. In addition, the base frame 3 is
It is designed to be pivoted to a mounting base (island base) via a mounting fixture 66 fixed to the.

In the above-described embodiment, the glass frame 1 is also connected to the attachment part 14 of the upper tray 12 and the outlet 11 for the prize ball.
The glass frame 1 is constructed as an integrated molded product, but the glass frame 1 is similar to the conventional one.
The present invention is equally applicable even if the glass frame made of a metal frame and the front frame to which the upper plate is attached are configured separately.
