    摘要： The present invention discloses a low-noise reset control system of a light fixture comprising a supporting member, a pivoting member and a driver. The pivoting member includes a light source. A limiting portion is arranged on the pivoting member. A blocking portion matched with the limiting portion to limit a rotation angle of the pivoting member is arranged on the supporting member. The system further comprises an angle detector that senses a rotation angle of the supporting member and an angle indicator that sends out an indication signal when the pivoting member is at a specific angular position. In a light reset process, when the pivoting member rotates in a forward direction until the limiting portion is limited by the blocking portion, the driver immediately brakes so as to avoid noise caused by that the limiting portion repeatedly collides with the blocking portion, and after the pivoting member is driven to rotate by a certain angle in a reverse direction at a low speed, a transmission member is loosened and vibration of the pivoting member is completely dissipated so as to avoid inaccurate positioning in looking for a relative initial position later, and then the speed is increased to continue to drive the pivoting member to rotate in the reverse direction to look for the relative initial position.

    摘要： An electronic apparatus (3) comprises: a rotating body (71) having an outer thread (72) formed on the outer circumferential face thereof; and a cylindrical part (70) having an inner thread (78) formed on the inner circumferential face thereof, wherein the inner thread (78) screws to the outer thread (72) of the rotating body (71). An opening (73) is formed in an outer circumferential face of the rotating body (71). The rotating body (71) also comprises a rotating member (B4) that is exposed to the outside in the diameter direction from the opening (73), and that rotatably contacts the inner circumferential face of the cylindrical part (70). A first recess (75), that inhibits the rotation of the rotating member (B4), is also formed on the inner circumferential face of the cylindrical part (70).
