Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker arrangement structure for a gaming machine. More specifically, the arrangement structure for a speaker that outputs a sound effect of a game is improved to simplify wiring processing and produce a clear sound. The present invention relates to a speaker arrangement structure of a game machine that can be discharged.

[0002]

2. Description of the Related Art Generally, in a pachinko machine using balls as a game medium, various sound effects are output in the middle of the game in order to raise the player's interest in various game modes.
Therefore, a speaker is arranged. The speaker is connected to the accessory control circuit board via wiring and emits a sound effect in response to a sound effect signal from the accessory control circuit board.

[0003]

By the way, in the conventional pachinko machine, the mounting position of the speaker is the lower part of the front frame on the back side of the pachinko machine (for example, near the back side of the ashtray).
Or it was often on the mounting frame on the back side of the plate. Therefore, there is a problem that work efficiency is low when processing the wiring existing between the accessory control circuit board installed on the base frame of the back mechanism board of the pachinko machine and the speaker.

The main reason for this is that the accessory control circuit board is installed on the base frame and the speaker is installed at a location apart from the base frame. Therefore, the wiring connecting them tends to be long, and moreover, they have been processed and routed so as to crawl on the upper part of the base frame or the lower part of the front frame.

The back mechanism board is composed of a base frame body which is attached to the back side of the front frame of the pachinko machine and is made of synthetic resin, and various unit parts arranged on the base frame body. This is a generic term.

Further, since the speaker is arranged on the back side of the pachinko machine, and the special opening (the opening for the speaker) for emitting the sound of the speaker to the front side of the pachinko machine has not been considered, it is clear. It was difficult to make a good sound. Inevitably, it sounded muffled and I couldn't produce a pure sounding sound effect.

Further, since the speaker and the ball ejecting device (conceivable for prize ball ejection and ball lending ejection) are located far from each other, there is a gap between the ball ejecting operation and the ejection sound emitted from the speaker. It was difficult to make a proper discharge sound according to the discharge operation.

[0008] In addition, conventionally, the surroundings of the speaker (especially,
Since there is no protective member in the rear) and no protective member for suppressing sound leakage, there is a problem that the speaker is not sufficiently protected or there is sound leakage. If there is sound leakage, there is a drawback in that the player's motivation is discouraged, for example, by hearing a large sound effect peculiar to the next big hit. Also, the operation unit for adjusting the volume of the speaker is not outside (for example, in the accessory control circuit board),
I couldn't easily adjust the volume.

In view of the above, according to the present invention, the wiring process is simple, a clear sound can be produced, an appropriate discharge sound can be produced according to the ball discharging operation, and the speaker is sufficiently protected to prevent sound leakage. It is an object of the present invention to provide a speaker arrangement structure of a game machine which can be performed and whose volume can be easily adjusted.

[0010]

In order to achieve the above object, a speaker arrangement structure of a gaming machine according to the present invention is attached to the back side of a gaming machine (for example, a pachinko machine 1) and various unit parts are arranged. The speaker 120 is attached to the base frame 84.
And the speaker 120 is attached to a position where sound can be emitted to the front surface of the gaming machine from an opening (for example, a ball discharge port 121) that exits from the rear surface side to the front surface side of the gaming machine.

In a preferred embodiment, the base frame 8 is
4 and a surface wall of a back mechanism board 90 composed of various unit parts arranged in the base frame 84, in a portion located on the back side of a discharge port 121 for discharging pachinko balls to the upper plate 21,
A plurality of holes 128 are formed, and the speaker 120 has a back mechanism from the back side of the gaming machine so that sound is emitted from the back side of the gaming machine to the front side through the outlet 121 through the plurality of holes 128. It is characterized in that it is attached to the board 90.

The speaker 120, the wiring processing section 133,
A cover member 78 integrally covering the ball discharging device 74 is provided, and the cover member 78 is formed with an opening 78K through which the volume operation portion of the speaker 120 can protrude.

[0013]

In the present invention, the speaker is attached to the front surface of the back mechanism board having a plurality of holes at the opening from the back side to the front side of the game machine, for example, the back side of the discharge port for discharging the pachinko balls to the upper plate. To be Therefore, the sound emitted from the speaker passes through the opening smoothly to the front of the game machine, and a clear sound can be produced. Also, the discharge sound can be heard by the player through the opening at an appropriate timing corresponding to the ball discharging operation.

Further, since the speaker is attached to the surface of the back mechanism board, the accessory control circuit board is also attached to the base frame, so that the wiring process between the two can be simplified. In addition, by covering the speaker with the cover member, the speaker can be sufficiently protected and sound leakage can be suppressed, and if the cover member is formed with an opening through which the speaker volume operation unit can project to the outside, the speaker volume can be reduced. Easy to adjust.

Since 8a is exposed to the outside through the opening 78K, the volume can be easily adjusted without removing the cover member 78.

In the above embodiment, one speaker is provided to output both the sound effect control sound effect and the ball discharge sound. However, the speaker is separately provided and the character effect control effect is obtained individually. A sound and a ball ejection sound may be output. Even in that case, the same effect as described above can be obtained by applying the present invention. For example, the speaker for discharging sound of the balls is provided in the opening of the upper plate, and the speaker for effect sound for controlling the accessory is arranged in another place. Further, the sound effect of controlling the accessory and the sound of ejecting the balls may be simultaneously output from one speaker.

Further, the ball discharge port 121, the cover member 78,
The shape of the wiring cover 141 and the like is not limited to the type of the above embodiment, and can be changed as appropriate according to the model of the game machine.
Any shape is possible within the scope of the present invention.

Further, the speaker arrangement structure of the gaming machine according to the present invention is not limited to the example applied to a part-credit type pachinko machine, but can be applied to all other pachinko machines. Further, even in a gaming machine which does not use a pachinko ball as a game medium, the same idea can be applied to a gaming machine having a speaker.

[0065]

According to the present invention, since the speaker is attached to the surface of the back mechanism board having a plurality of holes formed in the opening from the back side to the front side of the game machine, the sound emitted from the speaker is emitted. Can smoothly escape to the front side of the gaming machine through the opening, and a pure and clear sound effect can be produced instead of a muffled sound. Further, since the location of the speaker and the discharging position of the ball are the same and are the above-mentioned openings, there is no difference between the discharging operation of the ball and the discharging sound emitted from the speaker, and it is possible to accurately perform the discharging operation. You can make a discharge sound.

Further, since the speaker is attached to the surface of the back mechanism board and the accessory control circuit board is also attached to the base frame, the wiring process between the two can be simplified. Also, by covering the speaker with the cover member, the speaker can be sufficiently protected and sound leakage can be suppressed. Moreover, since the volume operation portion of the speaker is formed in the cover member with an opening through which the volume operation portion can project to the outside, the volume of the speaker can be easily adjusted.
