Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an improvement of a speaker mounting structure attached to a pinball game machine.

[Prior art] A pinball game machine generates various sound effects.
Many are equipped with speakers to liven up the atmosphere of the game. For example, in a pachinko game machine, which is an example of a pinball game machine, a sound effect is generated to notify the player when the game state has reached a specific game state that is advantageous to the player, and to enliven the atmosphere of the game. Has a built-in speaker. Further, another example of the pinball game machine, an arranged pachinko machine (so-called "ArePachi"), is also provided with a speaker for generating a sound effect when a game is completed, such as when indicator lights are lined up horizontally. Furthermore, many smart ball game machines, which are other examples of pinball game machines, are equipped with speakers for generating sound effects to liven up the atmosphere of the game.

By the way, as a mounting structure for the speaker in such a pinball game machine, there is one that has been generally known in the past, for example,
There was one described in Japanese Utility Model Application No. 55-175472. The speaker mounting structure for this conventional pinball game machine is that the bottom wall of the ball tray provided on the front side of the front plate is a double wall structure with a predetermined interval, and a sound-transmitting hole is formed in the bottom wall of the bottom wall. In addition to providing
A speaker was disposed within the interval to face the sound-transmitting hole, and the sound effect output from the speaker was configured to flow to the front of the pinball game machine via the sound-transmitting hole in the bottom wall. . With this configuration, it is possible to arrange the speakers by effectively utilizing the space formed in the bottom wall portion of the ball receiving tray.

[Problems to be solved by the invention] However, in the speaker mounting structure of this type of conventional pinball game machine, the speaker was directly attached and fixed to the bottom wall of the ball tray, so there were problems with the speaker mounting structure. It had the disadvantage of being unreasonable. In other words, since the bottom wall of the ball tray is a part of the ball tray that has the function of storing balls and supplying them to the ball firing position, its shape, structure, and size are naturally restricted, and it is not always possible to attach a speaker. In some cases, it may not be possible to design the optimal shape, structure, and size for the speaker, resulting in an unreasonable mounting structure, which may cause the speaker to loosen with use, resulting in poor sound, or the speaker may come off. There was a risk that defects such as leakage may occur.

By the way, the sound effect generated from the speaker in a pinball game machine depends on the surrounding atmosphere of the place where the pinball game machine is installed, that is, the gaming hall where the pinball game machine is installed. different. For example, one game center requires a pinball game machine with a speaker that outputs a relatively loud sound effect, while another game center requires a pinball game machine with a speaker that outputs a relatively quiet sound effect. This is how it works. Also, even within the same amusement park, the sound effects need to be louder in areas where people move frequently, such as near the entrance, and sound effects need to be louder in areas where there is relatively less movement of people at the back of the playground. There is a demand to make it smaller.

However, the above-mentioned conventional speaker mounting structure has the disadvantage that it cannot meet the above-mentioned demands of the game parlor because it does not have a mechanism for adjusting the volume of the sound effect.

In order to meet the demands of such amusement facilities,
For example, there was one described in Japanese Utility Model Application Publication No. 58-193986. In this conventional device, a volume adjuster for adjusting the volume of the sound effect emitted from the speaker is attached to the lower part of the front frame, and the volume of the sound effect can be adjusted by adjusting the volume adjuster. It was designed to be adjustable.

However, in this conventional device, since the volume adjuster is attached to the back side of the frame portion below the front frame, the volume adjuster cannot be adjusted unless the front frame is opened. However, there was a drawback that the volume could not be easily adjusted while the amusement park was in operation.

In view of these circumstances, the present invention has been developed to achieve a speaker mounting structure that effectively utilizes the space formed in the bottom wall of the ball tray, and to easily adjust the volume of the speaker. The purpose is to

[Means for Solving the Problems] A speaker mounting structure for a pinball game machine according to the present invention is provided with a ball tray on the front side of a front plate provided in a front frame so as to be openable and closable, and a bottom wall portion of the ball tray. are constructed in a double structure with a predetermined interval between them, a sound transmission hole is provided in the bottom wall of the lower part thereof, and an insertion opening through which a speaker can be inserted from the outside into the said interval is formed. , the speaker is inserted into the interval from the insertion opening with the speaker attached to the speaker attachment member, and is fixedly attached via the speaker attachment member, and the sound output from the speaker is varied on the back side of the front plate. It is characterized by being equipped with a volume adjuster.

[Function] According to the present invention, the bottom wall portion of the ball tray has a double structure with a predetermined interval, a sound-transmitting hole is provided in the bottom wall of the bottom wall, and a sound-transmitting hole is provided from the outside within the above-mentioned interval. An insertion opening into which a speaker can be inserted is formed.
The speaker is inserted into the space from the insertion opening with the speaker attached to the speaker mounting member, and is fixedly attached via the speaker mounting member. As a result, the speaker is installed through the speaker mounting member, a member prepared for mounting the speaker, which makes it possible to make the speaker mounting member into a shape and size that is optimally designed for mounting the speaker. Therefore, it is possible to easily arrange the speakers by effectively utilizing the space formed in the bottom wall portion of the ball receiving tray.

Moreover, if you want to change the speaker volume,
This can be achieved by a simple operation in which an attendant at the game center opens the front panel and adjusts the volume adjuster located on the back side.

[Example] Hereinafter, an example of the invention will be described in detail with reference to the drawings. In the following description of the embodiment, a pachinko game machine will be described as an example of a pinball game machine. However, it should be pointed out in advance that this invention is not limited to pachinko gaming machines, but can also be applied to other pinball gaming machines such as arrangement-type pachinko machines (commonly known as "ArePachi") and coin gaming machines.

FIG. 1 is a front view of a pachinko game machine to which a speaker is attached using the mounting structure of one embodiment of this invention, and the front frame and front plate are shown in an open state.

Referring to FIG. 1, a pachinko game machine 10 includes a front frame 12 in the shape of a rectangular frame. A glass door frame 14 and a front plate 16 are attached to the front frame 12 so that they can be opened and closed by rotating around one side, like a swinging door. On the back side of the front plate 16, a prize ball outlet 18 is formed on the upper side near the side (the right side in FIG. 1) that becomes the central axis when opening and closing.
The prize ball outlet 18 is for guiding the prize balls flowing out from the prize ball communication port 20 formed on the main body side of the pachinko game machine 10 to the front side of the front plate 16.
A ball tray (not shown in FIG. 1) for receiving prize balls coming out of the prize ball outlet 18 is attached to the front side of the front plate 16.

On the back side of the front plate 16 and below the prize ball outlet 18, a speaker mounting plate 24 including a volume controller 22 is attached. A speaker for generating sound effects (not shown in FIG. 1) is mounted on the front side of the speaker mounting plate 24. This speaker mounting structure is a feature of this embodiment, and will be described in detail later.

Further, on the back side of the front plate 16, a firing rail 3 is provided.
A ball leakage prevention plate 26, a ball extraction outlet 28, a batted ball supply device 30, etc. are provided to prevent No. 6 balls from coming off the track. Furthermore, in FIG. 1, 32 is a game board, 34 is a metal frame, 36 is a firing rail, 38 is a batting rod, 40 is an overflow ball passage, 42 is a ball outlet, 44 is an excess ball tray, and 46 is an operation These handles are already known in the construction of the pachinko game machine 10.

Figure 2 shows the pachinko game machine 1 explained in Figure 1.
0 is a back view of 0. When viewed from the back side, the pachinko gaming machine 10 has an outer frame 48 for holding the front frame 12 (see FIG. 1) defining an outer extension. Outer frame 4
8 and a mechanism plate 50 is attached thereto.
The mechanism board 50 is equipped with various mechanisms necessary for pachinko games, and the balls guided to the back side of the game board 32 (see FIG. 1) are processed in various ways by the mechanism board 50. Ru.

A control board 52 is located slightly below the center of the mechanism board 50.
is installed. The control board 52 is equipped with a control circuit for controlling various electrically driven devices (for example, a variable winning ball device, a winning lamp, a variable display device, a speaker, etc.) included in the pachinko gaming machine 10. It is. The control board 52 also includes, of course, an audio circuit (not shown) that outputs an audio signal to be generated from a speaker. 54 is an audio signal output supply wiring for transmitting a signal from the control board 52 to the speaker.

In addition, in FIG. 2, 56 is a ball-hitting drive unit, and 58 is a ball-hitting motor.

FIG. 3 is a view of the front panel 16 viewed from the front side, and is partially transparent to make clear the mounting position of the speaker, which is a feature of this embodiment. FIG. 4 is a rear view of the front plate 16, which is also partly drawn through. Furthermore, Figure 5 shows that
3 is a diagram showing a part of a side cross section of the pachinko game machine 10, including a portion where the front plate 16 shown in FIG. 3 is cut along the line -.

Next, referring to FIGS. 3 to 5, the speaker mounting position of this embodiment will be explained. A ball tray 60 is attached to the main surface of the front plate 16. The ball tray 60 receives and temporarily stores prize balls (pachinko balls) flowing out from the prize ball outlet 18, and also serves as a ball supply device 30 (see FIG. 1).
It is used to guide pachinko balls one by one.
As clearly shown in FIG. 5, the ball receiving tray 60 has a double wall structure consisting of a ball rolling member 62 and a cover member 64. In other words, the ball saucer 60
is a ball rolling member 62 for lining up and storing pachinko balls arranged at a gentle slope.
and a cover member 64 provided to cover the lower part thereof. Therefore, the bottom wall of the ball tray 4 has a double wall structure (double wall structure of the ball rolling member 62 and the cover member 64) when viewed from above.
I can say that I am getting used to it.

The lower left surface (lower left surface in FIG. 3) of the cover member 64 is sloped upward to the left, and a sound-transmitting hole 66 is formed there. Each of the sound transmission holes 66 has an elongated slit shape, and a large number of them are formed in parallel at equal intervals. The sound-transmitting hole 66 may be any hole that allows sound, that is, air vibration, to pass through.
Therefore, the hole is not limited to a large number of elongated parallel slit-like holes as in this embodiment, but may be a large number of round holes, square holes, or the like.

A speaker 68 is located inside the ball receiving tray 60 which has a double wall structure, that is, inside the space formed by the ball rolling member 62 and the cover member 64, at a position facing the part where the sound transmission hole 66 is formed. Built-in. The speaker 68 is held by a speaker mounting plate 24 attached to the back side of the front plate 16 and speaker mounting plates 70 and 71 projecting forward of the mounting plate 24. Furthermore, speaker mounting plate 2
4 is attached with a volume adjuster 22 that can be operated from the back side of the front plate 16.

In addition, in FIGS. 3 and 4, the members indicated by the reference numeral 72 included in the batted ball supply device 30 are as follows:
It is a ball feeding member, and 74 is a ball hitting outlet. In addition, in FIG. 5, 76 is a frame attached to the front frame 12, 78 is a game board mounting frame, and 80
82 is a flow path switching plate for switching the flow of prize balls to the ball receiving tray 60 or to the surplus ball receiving tray 44;
is a glass plate placed in front of the game board 32.

FIGS. 6 and 7 are diagrams for explaining the speaker mounting structure that is a feature of this embodiment.
In particular, FIG. 6 shows a speaker 68, a volume controller 22,
FIG. 3 is an exploded perspective view for explaining the coupling relationship between speaker mounting plates 24, 71, and 70. FIG. 7 is an exploded perspective view for explaining a mounting structure in which the assembly shown in FIG. 6 is mounted from the back side of the front plate 16.

Next, the speaker mounting structure of this embodiment will be explained with reference to FIGS. 6 and 7.

The speaker 68 is supported from the front and back by a speaker mounting plate 71 and a speaker mounting plate 70.
The speaker mounting plate 71 has a large round hole corresponding to the diameter of the diaphragm of the speaker 68 to be mounted. On the other hand, the speaker mounting plate 70 has a shape with the casing facing down so as to cover the back side of the speaker 68. The reason why the speaker mounting plate 70 is shaped like this is to improve the acoustic effect by covering the space on the back side of the speaker 68. Therefore, depending on the vibration characteristics of the speaker to be used, the rear side may be open, and the shape of the speaker mounting plate 70 does not necessarily have to be this way.

The speaker 68 held by the speaker mounting plates 70 and 71 is further mounted on the front side (left side in FIG. 6) of the speaker mounting plate 24. At that time, so that the vibration surface of the speaker 68 faces parallel to the sound transmission hole 66 formed on the bottom surface of the ball receiving tray 60,
Can be mounted diagonally.

The volume controller 22 includes a controller board 84, a switch 86 and a resistive element 88 disposed on the surface of the controller board 84.
a, 88b. The switch 86 is switchable in three stages, and is switched by sliding the adjustment knob 90 up and down in three stages. The volume controller 22 is attached to the front side of the speaker mounting plate 24. Note that an insertion hole 92 is formed in the speaker mounting plate 24, and the back side of the mounting plate 24,
That is, the adjustment knob 90 can be operated from the back surface of the front plate 16.

Although the above-mentioned members are connected to each other by screws, the members may be connected by other means such as an adhesive or recesses and projections for connection.

The above members are assembled and attached from the back side of the front plate 16 as shown in FIG. For this purpose, a mounting hole 94 is formed in the front plate 16. This mounting hole 94 constitutes an insertion opening through which a speaker can be inserted from the outside into the space formed by the double structure of the bottom wall portion of the ball receiving tray.

In addition, in FIG. 7, 96 is a push button switch.

FIG. 8 is a partial back view of the front plate 16 drawn to explain another example of the volume adjuster. In the embodiment shown in FIG. 8, the volume adjuster 22 has an adjustment knob 90 that rotates instead of sliding up and down as in the previous embodiment.
When the volume adjuster 22 is constructed as described above, there is no need to form the relatively large insertion hole 92 (see FIG. 6) in the speaker mounting plate 24 as described above.

FIG. 9 is a circuit diagram showing the electrical connection relationship between the speaker 68 and the volume adjuster 22. Referring to FIG. 9, one terminal of the speaker 68 is grounded, and the other terminal is connected to the control board 52 (see FIG. 2) via the volume controller 22. and,
A signal from the control board 52 is applied to the speaker 68 directly or via a resistor 88a or 88b by switching the volume controller 22. That is, in the state shown in FIG.
given to. Further, when the adjustment knob 90 is slid to the right and the terminals are short-circuited, a signal from the control board 52 is applied to the speaker 68 via the short-circuited terminal and the resistor 88b. Further, when the adjustment knob 90 is slid to the right and the terminals are short-circuited, a signal from the control board 52 is applied to the speaker 68 via the short-circuited terminal and the resistor 88a. Therefore, if the value of the resistor 88b is less than the value of the resistor 88a, then this circuit will set the volume of the speaker 68 at maximum when the adjustment knob 90 is on the right side, medium when switched to the center, and low when switched to the right side. It constitutes a three-stage switching circuit.

FIG. 10 is a diagram showing a specific connection relationship of the electric circuit explained in FIG. 9. In a specific circuit, the wires are connected by connectors 98a, 98b and connector 100.

Note that in order to increase the acoustic effect of the speaker 68,
It is preferable that the inside of the double wall structure of the ball receiving tray 60, that is, the inside of the space formed by the ball rolling member 62 and the cover member 64, be filled with a sound absorbing material such as foamed glass fiber. By doing so, in addition to improving the acoustic effect, there is also the effect that the collision sound of pachinko balls flowing on the ball rolling member 62 can be considerably absorbed.

[Effects of the invention] The present invention is designed to attach and fix the speaker via the speaker mounting member prepared for mounting the speaker. Therefore, the speaker can be arranged by effectively utilizing the space formed in the bottom wall portion of the ball receiving tray without any difficulty in terms of the speaker mounting structure.

Moreover, the volume of the speakers can be adjusted by the simple operation of opening the front panel by an attendant at the game hall.
