摘要： A scanner system includes a servo control unit. A rotation angle of a rotating shaft supporting a mirror is detected, and an error of the detected value with respect to a commanded value is integrated by an integral compensator so that the detected value is able to track the commanded value. A tracking error proportional compensator is disposed in parallel with the integral compensator so as to add a correction value proportional to the error to the integrated value of the error. A plurality of gains are prepared for each of the integral compensator, the tracking error proportional compensator, a detected value proportional compensator and a detected value differential compensator of the servo control unit. Each gain is changed in accordance with a travel angle of the commanded value. Thus, the mirror can be positioned quickly so that the machining speed can be improved.

摘要： A scanner has a rotor, and a stator disposed in the outside of the rotor. The rotor includes a shaft, and a permanent magnet mounted on the outer circumferential side of the shaft. The stator includes a casing, a yoke held in the inner circumferential side of the casing, and coils disposed in the inner circumferential side of the yoke. The permanent magnet of the rotor has radially depressed grooves formed in its outer circumferential portion. The torque constant of the scanner is circumferentially equalized by the grooves. Thus, positioning accuracy is improved.

摘要： An optical scanner which can realize target trajectory tracking machining at a high speed and with a high accuracy. In a servo control circuit controlling the operation of an X-axis scanner for positioning a mirror and the operation of a Y-axis scanner for positioning another mirror, sine wave response is performed at a specific frequency on feedback control for each axis so that the gain characteristic and the phase characteristic of the feedback control are estimated. This arithmetic operation processing is performed by a microprocessor prior to machining, and the results of estimation of the two axes are stored as data for each frequency. In the stage of machining, the results of estimation in terms of the gain characteristic and the phase characteristic are used for correcting the amplitude and phase of a sine wave of a target trajectory in order to cancel each characteristic.

摘要： A optical scanner control method and a optical scanner capable of positioning a mirror at a high speed independently of a rocking angle, and a laser machining apparatus for irradiating a printed circuit board with a laser beam by use of the optical scanner to thereby perforate the printed circuit board. In order to operate an actuator for rocking the mirror based on a deviation of a current position from an commanded value, a change in gain of the actuator is measured in accordance with each rocking angle in advance, and the manipulated variable of the actuator is corrected to cancel the change in gain. Thus, the influence of the alteration of a torque constant in accordance with the rocking angle can be suppressed so that the response characteristic becomes uniform all over a scanning region, and the positioning speed can be improved.
