摘要： Provided is an instrument pedal device that can be quieter when operated. According to the present invention, a pedal is rotatably supported on a base part by a first shaft. A rotation part is rotatably supported on the base part by a second shaft. A connection part is rotatably supported on the pedal by a third shaft. The connection part is rotatably supported on the rotation part by a fourth shaft. Urging force that is for making the pedal, as rotated from an initial position, return to the initial position is applied by a spring. The pedal can rotate from the initial position to a lowermost position in which the second shaft, the third shaft, and the fourth shaft are in the same plane. The urging force of the spring increases the closer the pedal gets to the lowermost position.

摘要： Provided is an electronic percussion instrument that can facilitate determination of contact of a detection target conductor with a head. An electronic percussion instrument includes: a tubular body portion with an end surface in an axial direction open; a head that covers the open end surface in the axial direction of the body portion and has a front surface adapted to be hit;and a capacitive sensor that has an electrode disposed on a rear surface side of the head, in which the head includes an electrically isolated conductive head, and no conductor connected to a reference potential point is provided between the front surface of the head and the electrode. In this manner, it is possible to facilitate determination of contact of the detection target conductor with the head.

摘要： A percussion instrument and a tension applying method are provided. A frame member where an outer edge of a membrane member is connected is arranged at the other side in the axial direction of a frame, and the frame member is tightened radially inward by a tension ring. The frame member has a predetermined elasticity, and a diameter of the frame member is reduced by a tightening force of the tension ring; thus, the tension may be applied to the membrane member by reducing the diameter of the frame member. That is, an edge portion of the membrane member may be uniformly pressed radially inward over the entire circumference by reducing the diameter of the frame member, and thus the tension may be uniformly applied to the entire membrane member.

摘要： Provided are an electronic percussion instrument and a hit detection method. An overhang portion constituting the outer edge part of an edge frame is positioned further radially outward than the outer edge of a bow frame. Consequently, when the overhang portion is hit, the vibration resulting from the hit is detected by an edge sensor attached to the edge frame. In this way, it is possible to detect whether the overhang portion (the edge portion of an electronic cymbal has been hit by means of vibration detection by the edge sensor instead of by means of pressure detection by a sheet sensor.

摘要： A frame body fixed to a membrane 10 is divided into multiple long-side frame bodies 11 and a short-side frame body aligned in a peripheral direction of a frame 3. Tension is applied to the frame body 10 by pulling each frame body 11, 12. Accordingly, it is not necessary to make the shape of each frame body 11, 12 consistent with the frame 3 (support part 30) in a complicated polygonal shape, and the shape of each frame body 11, 12 can be formed as a linear shape. Therefore, the shape of each frame body 11, 12 hardly varies. In addition, even if the shape of each frame body 11, 12 varies, tension can be uniformly applied to the membrane 10, as it is configured that each frame body 11, 12 is pulled to apply tension to the membrane 10.
