PROBLEM TO BE SOLVED: To achieve a Pachinko machine allowing a player to adjust to favorite sound quality.SOLUTION: If a performance button 9 is pressed when no performances are executed, an initial screen G for adjusting sound frequency characteristics appears on a performance indicator 30. Then, if the performance button 9 is pressed when a cursor G2 is positioned on low-pitched sound, a vertical bar of an indicator G1 showing a sound pressure level of the low-pitched sound extends upward, and the sound-pressure level of the low-pitched sound increases. When the vertical bar reaches the upper limit, it falls toward the lower limits. If pressing of the performance button 9 is stopped when a desired sound-pressure level is reached, the sound-pressure level at that time is set. The sound-pressure levels of middle-pitched and high-pitched sound can also be adjusted similarly. |
