Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a pachinko machine speaker for playing sound effects according to the progress of a game. Pachinko machines are designed to increase the interest of the game.
It is equipped with a sound generation device that generates various sounds, and the sound generation device is composed of a control device that electrically controls various winning devices and game devices arranged on the game board, and a speaker. There is.

Conventionally, this type of speaker has been attached not to the rectangular frame forming the outer shell of the Pachinko machine, but to the main body mechanism of the Pachinko machine that is fitted into the machine frame. For example, as shown in FIG. 3 of Japanese Patent Application Laid-Open No. 56-36983, it was attached to the back side of the main body mechanism. The back of the main body mechanism is exactly the back of the pachinko machine, and it is not the best position to play sound effects for players to hear.

The reason why speakers have been installed in less-than-optimal positions is because the speakers occupy a relatively large volume, so there is no physical space to install them on the front inside the main unit, which is close to the player. In addition to this, the reason seems to be that they were not able to change their thinking to install the device away from the control device due to the fact that sound effects are played depending on the progress of the game. In fact, a volume controller for adjusting the volume of the speaker was built into the control device.

However, since the control device is closely related to the prize-winning device and game device configured on the game board, when replacing the main body mechanism such as the game board with a new one, it is destined to be discarded along with the main body mechanism. Given the current situation in which tens of thousands of pachinko machines are manufactured for each model, it is extremely uneconomical to discard speakers and their volume controllers that are still usable, along with the main mechanism.

Additionally, if the speaker is installed on the back side of the main unit mechanism, not only will it require some effort to transmit the sound effects to the player in the front, but the speaker will also have to be placed within the specified depth of the machine frame to protect the main unit mechanism. This caused them to protrude and cause damage during assembly and transportation of the pachinko machine.

The present invention was made to solve this problem, and the speaker and its volume adjuster are installed in the machine frame of the pachinko machine, which remains on the island equipment side of the pachinko parlor even if the main body mechanism is replaced, and the mounting structure is also improved. The purpose is to provide a simplified pachinko machine.

Hereinafter, the present invention will be explained based on drawings showing an example of implementation.

1 and 3, a pachinko machine 1 consists of a front frame 2 in which a main body mechanism of the pachinko machine is installed, and a machine frame 3 in which the front frame 2 is detachably held.

The machine frame 3 is a vertically long rectangular frame that forms the outer shell of the pachinko machine 1, and on the lower front side (player side) of the machine frame 3, there is a frame that extends horizontally between the left and right vertical plates. It has a passed curtain board 18.

The front frame 2 is located above the curtain plate 18, and one side of the front frame 2 is locked to the left vertical plate of the machine frame 3 via a removable hinge, so that it can be opened in one direction.
The front side of this front frame 2 is equipped with front mechanisms that form part of the main body mechanism, such as a supply tray 5, a lower tray 6, and an operation dial 7, and the back side is equipped with a game board 4, a prize ball storage tank 8, etc. , the prize ball discharge device 9, the collection gutter 10, the prize ball processing device 11, the batted ball launch device 12, and the game control device 15 that electrically controls the prize winning devices and game devices 14 provided on the game board 4. A back mechanism 16 that forms part of the mechanism is equipped. The back mechanism 16 of the main body mechanism is configured to fit within the space surrounded by the machine frame 3 when the front frame 2 is closed.

In FIGS. 3 and 4, a speaker 17 for generating sound effects is inserted into a through hole 19 for mounting a speaker bored in the curtain plate 18. As shown in FIGS. The through hole 19 passes through the curtain plate 18 from the front side to the back side, and its diameter is large enough to accommodate the speaker 17. In the embodiment, the opening is provided at the center of the curtain plate 18 in the horizontal direction, but it does not necessarily have to be provided at the center.

The decorative plate 21 has through holes 1 from the front side of the curtain plate 18.
It is attached to cover the mouth of 9. On the back surface of the decorative plate 21, a locking protrusion 22 for supporting the speaker 17 on the decorative plate 21 is formed in a circular shape so as to be concentric with the diameter of the through hole 19. By fitting the peripheral portion 23 of the speaker 17 into the locking protrusion 22, the speaker 17 can be attached to the decorative plate 21.
can be assembled into. Of course, it is not limited to mere fitting, and may also be assembled to the decorative plate 21 using appropriate fastening means such as screws. Also, the locking protrusion 2
Since the decorative plate 21 is used to support the speaker 17, the decorative plate 21 does not necessarily need to be formed continuously in a circular manner, but may be scattered in correspondence with the peripheral edge 23 of the speaker 17. Decorative board 21
In the central part of the speaker 17, that is, in the area surrounded by the peripheral part 23 of the speaker 17, there is a small hole 2 for emitting sound effects.
A large number of 0 have been established.

A volume controller 24 for varying the output amount of the audio output signal from the game control device 15 is configured independently or separately from the game control device 15 and is attached to the speaker 17.

In the embodiment shown in FIGS. 3 and 4, a cylindrical body 26 made of a non-magnetic material is fitted into the core part 25 of the speaker 17 from behind, and the cylindrical body 26 is placed behind the core part 25.
This space 2 forms a space 27 surrounded by
7 includes a variable resistor 24A as a volume adjuster 24.
However, the present invention is not limited to the means shown in this embodiment, and it is sufficient that the volume adjuster 24 is integrally attached to the speaker 17. By integrally configuring the pachinko machine, the number of parts to be handled when assembling the pachinko machine is only the speaker, which facilitates parts management and assembly work.

That is, when installing the speaker 17, first install the speaker 17 to which the volume adjuster 24 is attached.
is integrally assembled with the decorative plate 21 via the locking protrusion 22, and the decorative plate 21 is pushed in from the front side of the curtain plate 18 by inserting the rear part of the speaker 17 into the through hole 19 first. , the decorative plate 21 is attached to the curtain plate 18. With just this work, the speaker 17 can be connected to the curtain plate 18, that is, the machine frame 3 through the decorative plate 21.
Fixed.

Reference numeral 28 in the figure is a back box, which is attached to the curtain plate 18 from behind the speaker 17, that is, from the back side of the curtain plate 18 so as to close the through hole 19. The back box 28 corresponds to the decorative plate 21, protects the rear side of the speaker 17 housed in the through hole 19, and also enhances the acoustic effect. This back box 28 is provided with a window 30 for exposing the adjustment lever 29 of the volume controller 24 to the outside of the back box 28 so as to correspond to the installed adjustment lever 29, so that the adjustment lever 29 can be accessed from the outside. It is designed to allow 29 adjustment operations.

Note that the back box 28 may be attached to the curtain plate 18 before or after the speaker 17 is attached.
Also, a variable resistor 24A as a volume controller 24
Even if it is a sliding type as shown in Figure 5,
It may also be of a dial type as shown as "24B" in FIG. In either case, variable resistor 2
The adjustment lever 29 (adjustment shaft in the case of a dial type) of 4A is made to face the window 30 of the back box 28 so that it can be adjusted from the outside. For example, the finger may be placed on the adjustment lever 29 through the window 30.

As mentioned above, in this invention, the speaker and its volume adjuster are integrated and attached to the curtain board that spans the lower part of the machine frame in the horizontal direction, so regardless of whether the main body mechanism is replaced with a new or old one, It can be used for a long time and is extremely economical.

In addition, when installing, the speaker with the volume adjuster attached can be integrated with the decorative plate, so the speaker, its volume adjuster, and the decorative plate can be attached by simply attaching the decorative plate to the curtain plate. It is easy to install and can significantly improve work efficiency.
By reducing the number of parts, the trouble of parts management can also be saved.

In addition, the particularly fragile cone part of the speaker is housed in the through hole of the curtain plate, and the speaker is installed close to the front by a length corresponding to the thickness of the curtain plate, and is housed within the depth and width of the machine frame. Since the rear of the speaker is protected by the back box, accidents caused by contact with the outside or impact can be prevented, and damage during assembly and transportation can be avoided.

Further, since the operating position of the adjustment lever of the volume controller is on the back side of the curtain plate, the volume can be easily adjusted by simply opening the front frame and placing your hand behind the machine frame. Therefore, in a game parlor where a large number of pachinko machines are installed or a game parlor where a wide variety of pachinko machines from several manufacturers are installed, the volume adjustment of the speaker can be quickly and easily performed to a desired volume.

Furthermore, since the speaker faces the player directly through the decorative board, clear sound effects with little distortion can be effectively heard with a small output.
