Title: Game machine
Inventor: YAMAMOTO SHINYA
IPC: A63F7/02
Filed: 2019-10-31
Abstract: To provide a game machine which can improve the convenience of adjusting a sound volume.SOLUTION: A sub-control CPU can execute a fade-out control by which a sound volume of a background music output in a waiting period is muted over time. Additionally, the sub-control CPU can adjust-control the sound volume in the waiting period. When the adjust-control of the sound volume is not carried out in a second period in which the fade-out control is executed, the sound volume of the background music output in the waiting period attenuates in a specific attenuation mode over time. Meanwhile, when the adjust-control of the sound volume is carried out in the second period, the sound volume of the background music changes in a mode different from the specific attenuation mode. Further, a time required from a start of the fade-out control to an end of the fade-out control is identical irrespective of a value of a sound volume flag at the moment of the start of the fade-out control.SELECTED DRAWING: Figure 6
