Abstract:
1. A pedal device used by a performer of an electronic keyboard apparatus, comprising: a pedal that is moved in response to a depression operation from the performer; a chassis that rotationally supports the pedal according to the depression operation to move the pedal downwardly about a supporting position supported by the chassis; a first reaction force application device that applies a first reaction force countering the depression operation of the pedal to the pedal; a second reaction force application device that is pre-compressed in a state during a first period of pedal depression from an initial state of no pedal depression until the amount of depression of the pedal reaches a specified amount, and is compressed in association with the depression operation of the pedal when the amount of depression of the pedal exceeds the specified amount during a second period, wherein the second reaction force application device applies a second reaction force with an elastic force countering the depression operation to the pedal; a restriction device located at a position between a position of the first reaction force application device and the operation position, wherein the restriction device restricts a lower limit position of the pedal by restricting rotational movement of the pedal, wherein the first reaction force application device is located between the supporting position of the pedal and the operation position, and wherein the first reaction force application device applies the first reaction force to the pedal at a position between the supporting position and the operation position, and wherein the second reaction force application device is located between a position of the first reaction force application device and the operation position, and is disposed opposite to the restriction device, and abuts against the restriction device when the amount of depression of the pedal exceeds the specified amount, wherein the second reaction force application device applies the second reaction force to the pedal at a position between a position of the first reaction force application device and the operation position, and wherein the second reaction force application device is compressed in association with the depression operation of the pedal.
