  In such a gaming machine 1, a game ball is launched toward the game area 922 by operating the launching device 94 (handle). When a game ball flowing down the game area 922 wins a winning opening such as a start winning opening 924, 925 or a big winning opening 926, a predetermined number of winning balls are paid out by the payout device. Other configurations and the like can be the same as those of a known gaming machine, and thus descriptions other than those related to the present invention are omitted.

  As shown in FIG. 2, the gaming machine 1 according to the present embodiment includes a main control board 20 and a sub control board 30 (corresponding to the board in the present invention). The main control board 20 is connected via a relay circuit 21 to sensors 22 for detecting that a game ball has won in the above-described start winning ports 924, 925, the big winning port 926, and the like. Further, the payout control circuit 23 is connected to a payout device such as a lending payout device 24 and a prize ball payout device 25, and a launching device via a payout control circuit 23 and a launch control circuit 26. The main control board 20 controls the jackpot lottery based on the winning of the game balls in the start winning ports 924 and 925, the payout of the game balls based on the winning of the game balls in various winning ports, and the like.

  The sub control board 30 mainly determines and controls an effect to be executed in response to a signal from the main control board 20 (success / failure of a big hit flag, a signal notifying that a game ball has won a predetermined winning area, etc.). To do. The effects include displaying an image on the display device 93, lighting and blinking various lights 32 (lamps), and outputting sound from the speaker 33. That is, the sub control board 30 is connected to the display device 93 (display control board), the lamp control circuit 31, the speaker 33, and the like.

  Among these functions, a sound control circuit 40 that is a circuit for controlling sound output from the speaker 33 is formed on the sub-control board 30. The audio control circuit 40 is a circuit that is driven by a CPU or the like mounted on the sub-control board 30.

  Details of the voice control circuit 40 are as shown in FIG. The sub control board 30 (CPU) that has received the various signals sent from the main control board 20 determines (lottery) an effect to be executed based on the signals. When the effect is accompanied by audio output, the sub-control board 30 outputs an audio signal used in the effect determined to be executed from the audio signal output means 41 (audio circuit; DSP (digital signal processor)). . The output audio signal is amplified by audio signal amplifying means 42 (amplifier circuit). The amplified signal is sent to the speaker 33 provided outside the substrate through an electric wire, and is output from the speaker 33 as a production sound.

  In the sub control board 30 in the present embodiment, a connection portion 44 is provided on a signal line 43 that connects the audio signal output means 41 and the audio signal amplification means 42 in the audio control circuit 40. The connection unit 44 is a port formed on the substrate for taking out the audio signal output from the audio signal output unit 41 before being amplified by the audio signal amplification unit 42.

  An example of voice confirmation at the design / development stage of the gaming machine 1 using the connection unit 44 is as follows. The connection unit 44 is configured by a through hole or a via (via hole) that is electrically connected to a signal line 43 that connects the audio signal output unit 41 and the audio signal amplification unit 42. Specifically, it is a conductive portion that is electrically connected to the signal line 43 inside a hole (hole) formed in the substrate.

  One end of the electric wire is directly or indirectly connected to the connection portion 44 via a connector or the like. A conversion device 50 (a device including a transformer can be exemplified as an example of an external device in the present invention) capable of adjusting a signal level is connected to the other end of the electric wire. After the signal level is adjusted by the conversion device 50, the signal is output from the confirmation sound output device 51 (mounted in the gaming machine 1) different from the speaker 33 mounted in the gaming machine 1, such as headphones, earphones, and external speakers. Output from a device having a lower output level than the speaker 33, and the sound is confirmed. In addition, without using the audio output device 51, using a confirmation device (corresponding to another example of the external device in the present invention) that can visually confirm (monitor) whether the audio output is normally performed. Also good.

  After the voice confirmation is completed, the electric wire, the connector and the like are removed from the connection portion 44 (sub control board 30). As a result, the components other than the point where the through holes and vias that are the connection portions 44 remain are shipped as gaming machines 1 on which the sub control board 30 that is not different from the conventional sub control board is mounted.

  As described above, in the gaming machine 1 according to the present embodiment, the audio signal output from the audio signal output unit 41 is converted into audio using the connection unit 44 provided in the sub-control board 30 (audio control circuit 40). It can be taken out at a stage before being amplified by the signal amplification means 42. Therefore, it is not necessary to greatly reduce the amplified high-level signal for the sound output device 51 such as headphones or earphones as in the conventional case, so that it is easier to adjust the level when confirming the sound than in the past. Is possible. Moreover, it is possible to suppress the heat generation of the conversion device 50 and the deterioration of the sound quality.

  Further, since the connection portion 44 is merely a “hole” formed in the substrate such as a through hole or a via, if the electric wire or the connector is removed from the connection portion 44 after the voice confirmation is completed, the connection portion 44 remains. Other than this, it is no different from the conventional substrate. Therefore, it is not necessary to change the shape of the case for storing the substrate. In addition, it is conceivable that a connector is mounted on the board in advance as the connecting portion 44. However, if the connector that is not fitted with anything is left on the board and shipped as a product, the connector is illegal. Although there is a possibility of being used for an act, such a problem does not occur because the connecting portion 44 is a through hole or a via.

  Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.
