Description

[Detailed description of the invention] This invention relates to a pachinko machine, and more specifically, a mechanism frame in which mechanical parts such as a prize ball case and a safe ball detector, which are installed on the back of a pachinko machine, are molded from synthetic resin. This invention relates to an improvement in a pachinko machine which can be stored in the body in advance and assembled by attaching the mechanism frame.

The inventor of the present invention has developed a prize ball case that controls the release of prize balls, and a prize ball case that controls the release of prize balls, in order to quickly and easily assemble the pachinko machine, maintain it after assembly, inspect it, or replace parts. Mechanical parts called so-called back parts, such as a safe ball detector that detects and activates the prize ball case, are assembled in advance into one mechanism frame, and these mechanical parts are built in when the pachinko machine is assembled. We have proposed a pachinko machine that can be manufactured easily and quickly by attaching a mechanism frame with a mechanical frame, but the present invention further improves this mechanism frame, and especially improves the above-mentioned built-in prize ball. Holding and inspecting the case, installing parts,
It is an object of the present invention to provide a pachinko machine in which replacement can be performed more smoothly.

Hereinafter, an embodiment illustrating the present invention will be explained and its features will be explained in detail. Fig. 1 is a rear view of the pachinko machine of the invention, Fig. 2 is an enlarged front view of the main parts, and Fig. 3 is a front view of the pachinko machine of the invention. This is an enlarged right side view of the main part as a cross section. In the figure, 1 is the machine frame, 2 is the door frame attached to the machine frame by screwing one side edge, and 3 is the back side of this door frame. It is a metal mechanism frame formed into a fixed shallow box shape.

The front of the mechanism frame 3 is open so that the game board housed inside can be seen from the front of the pachinko machine through the opening, and the back is equipped with a safe ball detector that detects and controls safe balls and a prize ball. It is equipped with various mechanical parts, including a prize ball case for ejecting balls.

4 is a tank for storing prize balls in order to replenish them to the prize ball case 5; 6 is a cover that covers a guide gutter that guides the balls from the storage tank 4 to the prize ball case 5;
7 is a mechanism frame made of synthetic resin that houses a prize ball case 5 and a safe ball detector (not shown); 8 is a frame 9 provided vertically on the lower surface of one side of the cover 6; Just when it is surrounded is a rear cover that covers a safe ball-closing room provided behind the game board (not shown).

The mechanism frame 7 has two front and rear plates 10 and 11 arranged opposite each other with a gap between them, and two rows of guide gutter 12 for guiding prize balls into the space provided between them, and a constant number of prize balls following the guide gutter. a prize ball case 5 that stores and releases the safe balls in response to the incoming safe balls; a discharge gutter 13 that guides the balls released from the prize ball case to a prize ball tray provided on the front of the aircraft; A ball extraction gutter 14 and the like are provided vertically along the line, and a safe ball detector (not shown) is provided below the gutter.

The prize ball case 5 is provided following the guiding gutter 12, and its lower end opening faces the prize ball discharging gutter 13.
Normally, this lower end opening is closed with a stopper member 16 which is freely swingable about the support shaft 15 to stop the release of the stored prize balls.

The stopper member 16 closes the lower end opening of the prize ball case by engaging the pin 18 with the swinging member 17, and the swinging member 17 controls the operation rod 19 that transmits the operation of a safe ball detector (not shown). When the ball is pushed up and swung around the support shaft 20, the pin 18 is removed, the prize ball case is opened, and the stored prize balls can be discharged into the discharge gutter.

In the figure, 21 is a spring that always urges the prize ball case 5 to be close to the stopper member 16 side.
23 is a stopper rod that is pulled toward the stopper member side by the bias of this spring 21 and restrains the posture of the prize ball case with its lower end opening facing the discharge gutter 13, and 23 releases the restraint of this stopper rod. 24 is a solenoid that opens the prize ball case to the ball extraction gutter 14, and 24 is a solenoid that opens the prize ball case to the ball extraction gutter 14.
This is a cover that covers the solenoid 23 and the like.

The spring 21 is stretched between a shaft 25 protruding from the prize ball case and a pin 26 set on the plate 10.
The solenoid 23 is attached to a locking pawl 27 that stands up from the surface of the plate 10, and the cover 24 is attached to the surface of the plate 10 so as to cover these.

The cover 24 shown here is molded from a flexible, elastic thermoplastic synthetic resin such as polypropylene, and can be bent onto the lower end of the box-shaped main body that covers the spring 21, etc. A mounting piece 29 is integrally provided via a thin hinge part 28,
The inner surface near the upper end is also integrally provided with a fitting part 31 into which a locking boss 30 raised from the plate 10 of the mechanism frame is fitted.

This cover fixes the plate 10 by fixing the mounting piece 29 with screws 32, and can be opened and closed freely by bending the hinge part 28, and the fitting part 31 is always engaged. It is pressed against the locking boss 30 and is press-fitted into the pocket 33 of the locking boss 30 to be held in a closed state. As shown in FIGS. 2 and 3, the fitting part 31 has a pocket 33 formed at a required depth to receive the tip of the locking boss 30, and the inner width of the pocket is set to the same depth as that of the boss 30. It is made to approximately match the outer diameter of the tip, and when pressed together, the elasticity of the material allows them to fit tightly together, and from this state they do not easily separate due to frictional force. Here, in order to prevent the cover from opening unexpectedly, a set screw 35 is inserted into a female threaded hole 34 provided from the front side of the cover along the axis of the boss 30 to restrain free opening.

The present invention is constructed as described above, and among the attached parts of the prize ball case 5 that are housed inside the mechanism frame, the stopper rod 22, solenoid 23, etc., which are the means for removing balls, are located on the plate 10 of the mechanism frame. However, since these are always covered by a cover 24 that can be opened and closed, there is a risk that they may be damaged by unexpected shocks during transportation from the factory or during use in the hall. On the other hand, this cover is attached to the mechanism frame 7 via a thin hinge part 28 with an integrally provided mounting piece 29, and when opening and closing, this cover can be opened and closed using this hinge part as a bending point. In addition to being easy to open, if the mounting piece 29 is placed downward and the free upper end is pulled out toward you as described in the previous embodiment, the open position is maintained by the weight of the cover. This is extremely convenient when maintaining and inspecting the ball case or replacing parts.

Furthermore, in the present invention, when the cover is closed, the upper end of the cover is pressed to connect the fitting part 31.
The locking boss 30 can be received and locked in the pocket 33 of the valve body 33, and the closed state can be maintained, so that it can be easily closed. Of course, since the cover of the present invention is an integrally molded synthetic resin product, it can be manufactured at a low cost, and it can be mounted by simply screwing the mounting piece 29, or in some cases. Since it can be easily attached to a predetermined position on the mechanism frame by bonding with an adhesive, it is also effective in terms of workability and productivity.
