Abstract

To prevent a game effect from being impaired by generation of a sound in an unintended sound volume.SOLUTION: When a blackout performance is performed, control for decreasing the sound volume is executed to set the sound volume of each channel to volume 0 by rewriting sound volume data of each channel. At this time, the sound volume of reserved channels 5-15 are set to 0 as well as channels 0-4 now being used. Since the sound volumes of the reserved channels 5-15 are set to 0 as well as the channels 0-4 now being used in this way, a game effect is prevented from being impaired by generation of a sound in an unintended sound volume during execution of a blackout performance.SELECTED DRAWING: Figure 3

  The present invention relates to a gaming machine that performs a game.

  As a gaming machine, a game medium such as a game ball is launched into a game area by a launching device, and multiple types of identification information are variably displayed when the game medium wins in a start prize area such as a prize opening provided in the game area. There are pachinko machines in which a predetermined number of bets are set and a slot machine in which a plurality of types of identification information (for example, symbols) are variably displayed when a start operation is performed. In a gaming machine configured to be able to execute variable display of identification information in this way, when the display result of variable display of identification information becomes a predetermined display result in the variable display unit, a predetermined game value (for example, jackpot) Some are configured to give the player a transition to a state, etc.).

[First Embodiment]
[Composition of gaming machine]
FIG. 1 is a diagram showing a gaming machine 1 according to the present embodiment. As shown in FIG. 1, the gaming machine 1 according to the present embodiment includes a liquid crystal display 51 that displays an image, and speakers 53 and 54 that output sounds such as effect sounds and error sounds. The gaming machine 1 performs an effect when a game is being played. The effect is executed by displaying the effect image from the liquid crystal display 51 and outputting the effect sound from the speakers 53 and 54. An example of an effect using the liquid crystal display 51 is a blackout effect. The blackout effect is an effect of displaying an image (specific image) that renders the effect image, the effect symbol, the background image, and the like invisible on the liquid crystal display 51.

[Block Diagram]
FIG. 2 is a block diagram showing the configuration of the gaming machine 1. As shown in FIG. 2, the gaming machine 1 is provided with a game control board 40 and an effect control board 90. The game state is controlled by the game control board 40, and the effect control board 90 provides an effect according to the game state. Is controlled.

  The game control board 40 is constituted by a microcomputer having a main CPU 41a, ROM 41b, RAM 41c, and I / O port 41d. The game control board 40 performs processing related to the progress of the game and directly controls each part of the control circuit mounted on the game control board 40. A main control unit 41 is mounted to control automatically or indirectly.

  The effect control board 90 is configured by a microcomputer including a sub CPU 91a, ROM 91b, RAM 91c, and I / O port 91d, and is mounted with a sub control unit 91 that controls the effect. In other words, the sub-control unit 91 controls the slot machine 1 by controlling the effect.

  An effect device such as a liquid crystal display 51 and speakers 53 and 54 is connected to the effect control board 90, and these effect devices are driven based on control by the sub-control unit 91 mounted on the effect control board 90. It has become so.

  In the present embodiment, the main control unit 41 transmits various commands to the sub-control unit 91 via the parallel output port. A command transmitted from the main control unit 41 to the sub control unit 91 is sent in only one direction, and no command is sent from the sub control unit 91 toward the main control unit 41.

  In response to the command transmitted from the game control board 40, the sub-control unit 91 performs various controls for performing an effect, and directly or indirectly controls each part of the control circuit mounted on the effect control board 90. Control. The control circuit includes an audio output circuit 94. The audio output circuit 94 executes control to output effect sound from the speakers 53 and 54 based on a command from the sub-control unit 91 and sound data and sound volume of effect sound set for each of a plurality of channels. Specifically, when receiving a command from the sub-control unit 91, the audio output circuit 94 reads the audio data and volume of the compressed effect sound from the ROM 91b, and decodes (decodes) the read audio data and volume. , Stretch). The audio output circuit 94 includes 16 channels (channels 0 to 15) as audio output channels (in other words, playback channels), and can simultaneously output 16 types of independent audio. Then, the audio output circuit 94 outputs a production sound specified from the audio data decoded in the plurality of channels from the speakers 53 and 54 according to the set volume. That is, the sub-control unit 91 can set the sound data that can specify the effect sound and the volume of the sound output from the speakers 53 and 54 by a command to the sound output circuit 94 in each of the plurality of channels.

  The volume of the effect sound output from the speakers 53 and 54 can be adjusted by setting the volume for each channel, and can be adjusted by controlling the attenuator provided in the audio output circuit 94. Each channel can be set to any one of the following three types of volume. The adjustment by the attenuator can be adjusted from the maximum volume to the minimum volume (that is, mute). An attenuator is provided for each channel. Since the volume data is 8 bits (1 byte), it can be set in 256 stages, but in this embodiment, it can be set in 3 stages. Thereby, the data for adjusting the volume can be reduced. Note that the volume setting need not be limited to three stages, but it is preferable to set the volume so that the difference in volume increases as the volume increases. As a result, fine adjustment is possible when the volume is decreased, but rough adjustment is possible when the volume is increased. Thereby, the convenience can be improved.

[Type and volume of production sound for each channel]
As shown in FIG. 3, the audio output circuit 94 has 16 channels (channels 0 to 15) as output channels for effect sound, and can output 16 types of effect sound independently. In each channel, the volume can be set for each effect sound to be output. In the present embodiment, the volume of the effect sound can be set from three stages. Specifically, any one of volume “255”, volume “100”, and volume “0” can be set, volume “255” is the maximum volume, and volume “0” is the minimum volume (that is, Mute).

  As shown in FIG. 3A, channel 0 is a channel that outputs BGM1. FIG. 3A shows an example in which the volume is set to “255” in channel 0. Channel 1 is a channel that outputs BGM2. FIG. 3A shows an example in which the volume is set to “255” in channel 1. Channel 2 is a channel that outputs BGM3. FIG. 3A shows an example in which the volume is set to “255” in channel 2. Channel 3 is a channel that outputs a warning sound. FIG. 3A shows an example in which the volume is set to “255” in the channel 3. Channel 4 is a channel for outputting the character lines. FIG. 3A shows an example in which the volume is set to “255” in the channel 4. Channels 5 to 15 are unused channels. Since channels 5 to 15 are unused channels, no volume is set for channels 5 to 15.

  As shown in FIG. 3B, when executing the blackout effect, the sub-control unit 91 executes volume reduction control, and rewrites the volume data of each channel to change the volume of each channel to volume “0”. Set to. At this time, not only the used channels 0 to 4 but also the volume of the unused channels 5 to 15 are set to “0”.

  In this way, when the blackout effect is executed, the volume of the unused channels 5 to 15 is set to “0”, not only for the channels 0 to 4 that are being used. The output effect can be prevented from being impaired.

  Further, since the volume reduction control is executed and the volume is set to “0”, the volume of the production sound can be reliably prevented from being heard.

  In addition, since the volume reduction control is executed when the blackout effect is executed, the effect can be enhanced in conjunction with the display of the specific image on the liquid crystal display 51 when the blackout effect is executed.

  In the present embodiment, a special sound is output from a specific channel when the special condition is satisfied, and the volume reduction control is performed even if a predetermined condition for executing the volume reduction control is satisfied for the specific channel. It is possible to control not to execute. For example, it is assumed that the blackout effect is executed under a predetermined condition in which the volume reduction control is executed. Also, special conditions are that a game ball has won a start winning opening in a pachinko game machine, or that a stop switch for stopping a rotating reel has been operated in a slot machine, and channel 6 is designated as a specific channel. In addition, the channel 6 is output when a start winning sound that is output when a game ball wins a start winning opening in a pachinko gaming machine or when a stop switch for stopping a rotating reel is operated in a slot machine. Stop sound is output as a special sound. Then, when executing the blackout effect, the sub control unit 91 sets the volume to “0” for channels other than the channel 6 and sets the volume for the channel 6 so as not to decrease the volume. Thereby, the start winning sound and the stop sound are output even when the blackout effect is executed. By configuring in this way, the output of the start winning sound and the stop sound, which are special sounds, is secured, so that the game ball has won the start winning opening in the pachinko gaming machine, which is a special condition, and the slot machine rotates. It can be suitably notified that the stop switch for stopping the reel inside has been operated.

[Commands to output production sound]
FIG. 4 shows the types of commands transmitted from the sub-control unit 91 to the audio output circuit 94 in order to output the production sound from the speakers 53 and 54. The commands 1 to 5 include data indicating which of the plurality of types of effect sounds is output and data indicating the volume of the effect sound. Commands 6-8 consist only of data indicating the volume of the production sound. Hereinafter, commands 1 to 5 may be referred to as first commands (corresponding to first information), and commands 6 to 8 may be referred to as second commands (corresponding to second information).

  As shown in FIG. 4, the command 1 is a command indicating that the BGM 1 is output with the volume “255”. Command 2 is a command indicating that BGM2 is output at a volume “255”. The command 3 is a command indicating that the BGM 3 is output with the volume “255”. Command 4 is a command indicating that the warning sound is output at the volume “255”. Command 5 is a command indicating that the speech is output at the volume “255”. Command 6 is a command indicating only the volume “255”. Command 7 is a command indicating only the volume “100”. Command 8 is a command indicating only the volume “0”.

  First, the sub control unit 91 transmits one of the commands 1 to 5 (that is, the first command) to the audio output circuit 94. Thereby, the sub-control unit 91 instructs the sound output circuit 94 to output a specific effect sound (that is, the specific sound) and the same volume (volume “255”) output from the speakers 53 and 54 among the plurality of types of effect sounds. To do. Next, the sub control unit 91 transmits any of commands 6 to 8 (that is, the second command) to the audio output circuit 94. Thus, the volume of the effect sound output from the speakers 53 and 54 is instructed to the specific volume indicated by the second command. When the audio output circuit 94 receives any one of the commands 1 to 5, the audio output circuit 94 decodes the audio data and the sound volume to the channel corresponding to the designated specific effect sound. Further, when any of the commands 6 to 8 is received, the audio output circuit 94 decodes the volume into a channel corresponding to the specified specific effect sound. Thereby, the sub-control unit 91 can set the data for specifying the effect sound and the volume of the sound output from the speakers 53 and 54 in each of the plurality of channels of the audio output circuit 94. The audio output circuit 94 then outputs a volume (volume “255”) from the channel corresponding to the specific effect sound indicated by the received command (for example, the channel 1 corresponding to BGM1 indicated by the command 1 when the command 1 is received). )) To output a specific performance sound. Next, when any of the commands 6 to 8 is received, a specific effect sound is output according to the specific volume (volume “255”, volume “100”, or volume “0”) indicated by the received command. To do. Through such a series of controls, a specific effect sound is output at a specific volume. It should be noted that the volume of the period from when one of commands 1 to 5 is received and output of a specific performance sound is started until one of commands 6 to 8 is received and one volume is changed to a specific volume The period is such that the player cannot recognize the change. Therefore, the player sounds as if the specific production sound indicated by any of the commands 1 to 5 is started to be output at the specific volume indicated by any of the commands 6 to 8 from the beginning.

  In this way, after transmitting the commands 1 to 5 (first command) indicating which kind of effect sound is to be output and one volume (maximum volume “255”), the specific volume (volume “255”, volume “ The production sound is output at a specific volume by transmitting commands 6 to 8 (second command) indicating any one of “100” and volume “0”), so three types of specific volume commands are prepared for each production sound. Therefore, it is possible to reduce the data prepared for outputting the production sound.

  In addition, since the commands 1 to 5 (first command) indicate the volume “255” which is the maximum volume, it is possible to set the output of the production sound so that the production sound can be heard reliably.

  Moreover, since the volume is set using the second commands 6 to 8 common when outputting BGM1, BGM2, BGM3, the warning sound, and the speech, it is possible to reduce the data prepared for outputting the production sound. .

  In addition, the sub control unit 91 transmits a second command when the volume change condition is satisfied after the output of one effect sound (BGM1, BGM2, BGM3, warning sound, or speech) is started. Since the control for changing the volume of the effect sound is performed, data prepared for outputting the effect sound can be reduced.

  Note that the sub-control unit 91 continuously transmits any one of the commands 1 to 5 and any one of the commands 6 to 8 at one opportunity (for example, operation of a start switch, launch of a game ball, and start of symbol change). , A different command is not transmitted between any one of the commands 1 to 5 and any one of the commands 6 to 8. This can prevent an unintended instruction from being given to the audio output circuit 94.

  Further, as described above, in the gaming machine 1, the volume type (stage) can be set to 256 types, but in this embodiment, it can be set from three types (stages). Therefore, the second command indicates three types of volume, which are lower than the settable 256 types of volume, as the specific volume. Thereby, the data prepared in order to output a production sound can be reduced.

[Production sound output processing]
Next, the effect sound output process executed in the timer interrupt process executed by the gaming machine 1 at regular time intervals (about 0.56 milliseconds in the present embodiment) will be described.

  As shown in FIG. 5, in the effect sound output process, first, it is determined whether or not an effect sound output start condition is satisfied (Sb1). When the production sound output start condition is not satisfied, the process ends.

  When the production sound output start condition is satisfied, the sub-control unit 91 transmits the first command (any one of the commands 1 to 5 shown in FIG. 3) to the audio output circuit 94 (Sb2). When the audio output circuit 94 receives the first command, the audio output circuit 94 decodes the audio data and the volume to the channel corresponding to the specified specific effect sound, and the first effect sound indicated by the first command is the first. The sound is output from the speakers 53 and 54 at one volume (maximum volume “255”) indicated by the command.

  Next, the sub control unit 91 transmits the second command (any one of commands 6 to 8 shown in FIG. 3) to the audio output circuit 94 (Sb3). When the audio output circuit 94 receives the second command, the audio output circuit 94 decodes the channel volume corresponding to the specified specific effect sound, and the volume of the specific effect sound is indicated by the second command from the speakers 53 and 54. Change to a specific volume.

  As described above, in this embodiment, since the first command indicating the specific sound volume and the first sound volume is transmitted and then the second command indicating the specific sound volume is transmitted, the sound effect is output at the specific sound volume. Data prepared for outputting sound can be reduced.

[Volume reduction control processing]
Next, a sound volume reduction control process executed in a timer interrupt process executed by the gaming machine 1 at regular time intervals (about 0.56 milliseconds in this embodiment) will be described.

  As shown in FIG. 6, in the volume reduction control process, it is first determined whether or not a game has been started (Sa1). When it is determined that the game has not started, the process is terminated.

  When it is determined that the game has started, it is determined whether or not the execution of the blackout effect has started (Sa2). That is, when the execution of the blackout effect is started, it is determined whether or not a predetermined condition for executing the volume reduction control is satisfied.

  When the execution of the blackout effect is started, the sub-control unit 91 transmits a second command (command 8 shown in FIG. 3) for setting the output sound volume of the effect sound to 0, to the sound output circuit 94. The volume of each channel is set to 0 (Sa3). That is, the audio output circuit 94 sets the volume of each channel to 0 when the second command transmitted by the sub-control unit 91 is received. Each channel includes not only channels 0 to 4 used for outputting the production sound but also unused channels 5 to 15. The audio output circuit 94 sets the volume of all channels 0 to 15 to “0”. Set.

  When the output of the effect sound is started before the blackout effect is executed, the volume of the effect sound is changed by executing the blackout effect. Therefore, it can be said that the execution of the blackout effect satisfies the volume change condition.

[Second Embodiment]
Next, the second embodiment will be described, but detailed description of the parts common to the first embodiment will be omitted. In the first embodiment, the blackout effect is executed as a predetermined condition for performing the volume reduction control. In the second embodiment, an error occurs in the predetermined condition for performing the volume reduction control. It is embodiment to do.
[Volume reduction control processing]
In the second embodiment, a volume reduction control process executed in a timer interrupt process executed by the gaming machine 1 at regular time intervals (about 0.56 milliseconds in this embodiment) will be described.

  As shown in FIG. 7, in the volume reduction control process, it is determined whether or not an error has occurred (Sc1). If no error has occurred, the process ends. When an error occurs, the sub-control unit 91 sets the volume of each channel to 0 by controlling the attenuator (Sc2). Each channel includes not only channels 0 to 4 used to output the production sound but also unused channels 5 to 15. The sub-control unit 91 sets the volume of all channels 0 to 15 to “0”. Set (see FIG. 3).

  As described above, in the second embodiment, the sub-control unit 91 performs volume reduction control when an error occurs, and controls the attenuator without rewriting the volume data of each channel, thereby controlling the volume of each channel. Is set to volume “0”. At this time, not only the used channels 0 to 4 but also the volume of the unused channels 5 to 15 are set to “0”. When an error occurs, an error sound is output by executing the interrupt process. Therefore, it can be said that the volume of each channel is set to the volume “0” when the error sound is output.

  Thus, when an error occurs (in other words, when an error sound is output), the volume of unused channels 5 to 15 is set to “0” as well as the channels 0 to 4 being used. It is possible to prevent a production sound from being output at an unintended volume and impair the production effect.

  Further, since a predetermined condition for executing the volume reduction control is satisfied when an error occurs and an error sound is output, control can be performed so that the error sound can be heard.

  In the present embodiment, it is possible to execute a sound output stop control for stopping sound output when a sound output stop condition is satisfied. In this case, the output of the sound in the channel for which the sound data of the production sound is set is stopped, and the output of the sound is also stopped for the channel in which the sound data is not set. For example, it is assumed that an error has occurred as a stop condition. Then, in the example of FIG. 3, when an error occurs, the sub-control unit 91 stops outputting the sound of the channels 0 to 4 where the production sound is set, and also uses the unused channels 5 to 15. Audio output is also stopped. Thereby, it can prevent that the audio | voice which is not intended is output and a presentation effect is impaired. Note that it is preferable that the error serving as the stop condition is an error that requires power interruption recovery. That is, for an error that requires power interruption, the output of the production sound is stopped, and the production sound is output at a volume that is initialized when the power is turned on again. As a result, volume reduction control is performed only for errors that can be recovered without interruption, and volume reduction control is not required for errors that need to be recovered from interruption, so that the processing can be simplified.

  In addition, although 1st Embodiment and 2nd Embodiment are demonstrated separately, it is possible to implement combining each embodiment. That is, it is possible to perform control according to the predetermined condition that is satisfied when the blackout effect is executed and an error occurs as the predetermined condition.

[Effect of this embodiment]
In the present embodiment, when performing volume reduction control when a predetermined condition is satisfied, the volume of the channel for which the effect sound is set is reduced, and the volume of the unused channel for which the effect sound is not set is also reduced. (In this example, the part shown in FIG. 3, the part that performs the process of Sa3 in FIG. 6, and the part that performs the process of Sc2 in FIG. 7).
Therefore, it is possible to prevent a production sound from being output at an unintended volume and impairing the production effect.

In the present embodiment, the volume reduction control is executed to set the volume to the volume “0” (in this example, the part shown in FIG. 3, the part for performing the process of Sa3 in FIG. 6, and the process of Sc2 in FIG. 7). Part to do).
Therefore, it is possible to reliably prevent the volume of the production sound from being heard.

In the present embodiment, the volume reduction control is executed when the blackout effect is executed (in this example, the part shown in FIG. 3 and the part performing the processing of Sa3 in FIG. 6).
Therefore, the production effect can be enhanced in conjunction with the blackout production.

In the present embodiment, the predetermined condition for executing the volume reduction control is satisfied when an error sound that is a specific sound is output (in this example, the process shown in FIG. 3 and Sc2 in FIG. 7 is performed. portion).
Therefore, control can be performed so that an error sound can be heard.

In the present embodiment, it is possible to execute sound output stop control for stopping sound output when a sound output stop condition is satisfied.
Therefore, it is possible to prevent a production sound from being output at an unintended volume and impairing the production effect.

In the present embodiment, volume reduction control is not executed for a specific channel even if a predetermined condition for executing volume reduction control is satisfied.
Therefore, it is ensured that a special sound is output, and the establishment of the specific condition can be suitably notified.

In the present embodiment, the first command (commands 1 to 5 in this example) indicating a specific effect sound and one volume (maximum volume “255”) is transmitted, and then the specific volume (volume “255”, volume) is transmitted. A specific effect sound is output at a specific volume by transmitting a second command (in this example, commands 6 to 8) indicating “100” or volume “0” (in this example, in FIG. 4). Part to perform the processing of Sb2 and Sb3 in FIG. 5).
Therefore, the data prepared for outputting the production sound can be reduced.

In the present embodiment, the first volume indicated by the first command (commands 1 to 5 in this example) is the maximum volume “255” (in this example, the portion shown in FIG. 4).
Therefore, the output setting of the production sound can be performed so that the production sound can be heard reliably.

In the present embodiment, the first specific sound (in this example, any of BGM1, BGM2, BGM3, warning sound, or serif) and the second specific sound (in this example, BGM1, BGM2, BGM3, warning sound, or serif) When outputting any one and other than the first specific sound, the volume is set using a common second command (commands 6 to 8 in this example).
Therefore, the data prepared for outputting the production sound can be reduced.

  In the present embodiment, when the volume change condition is satisfied after the output of one effect sound is started, the sub-control unit 91 performs control to change the volume of the one effect sound by transmitting the second command ( In this example, the portion for performing the processing of Sa3 in FIG. 6).

In the present embodiment, the first command and the second command are continuously transmitted without transmitting another command between the transmission of the first command and the transmission of the second command (in this example, FIG. 5 is a part for performing the processing of Sb2 and Sb3).
Therefore, it is possible to prevent an unintended instruction from being given to the audio output circuit 94.

In the present embodiment, the second command indicates a specific number of types of volume smaller than the settable volume types as the specific volume (in this example, as shown in FIG. 4, it can be set in 256 levels. (A part that can be made up of 3 levels)
Therefore, data for adjusting the volume can be reduced.
