Abstract:
1. A pedal apparatus of an electronic musical instrument comprising: a fixed supporting member; a lever supported by the fixed supporting member and pivotable by a player's depression of the lever from an initial state to a final state; a plurality of springs that exert spring force on the lever; and a movable supporting member that supports any of the plurality of springs and is displaceable in response to pivoting of the lever, wherein the fixed supporting member restricts the displacement of the movable supporting member when an amount of depression of the lever increases from the initial state to a first predetermined amount of depression occurring before the final state, wherein the plurality of springs comprise first to third springs, wherein the first spring exerts spring force on the lever at all times in a direction resisting the depression of the lever, and wherein when an amount of depression of the lever increases from the initial state to the first predetermined amount of depression, a rate of change in reaction force with respect to the depression is lower between the initial state and the first predetermined amount of depression than between the first predetermined amount of depression and the final state due to collaboration of the second spring, the third spring, and the movable supporting member.
