The driving signal generator generates a driving signal for driving the vibrational system of the deflector. The modulation timing signal generator generates a modulation timing signal as the reference time for regulating the amount of light from the light source. The deflection detector detects the deflection condition of light deflected by the deflector. The driving signal generator generates the driving signal based on information of the vibration condition detected by the vibration detector, and the modulation timing signal generator generates the modulation timing signal based on information of the deflection condition detected by the deflection detector.

摘要： 0 A light beam deflecting apparatus which measures the passing time of a light beam in reciprocating scans on a specified position on the scanning line, and then calculates time lag data corresponding to the time lag in the reciprocating scan of a light beam deflecting device with respect to the drive signal therefor. From a measurement of two passing times in forward and backward scans, timing data is calculated, corresponding to the modulation start or end time of the light beam within a scanning cycle period. The invention resolves the drawback, in a light beam deflecting device for displaying an image by reciprocating light beam scannings, of image variation by variations for example in amplitude, phase and offset.

摘要： An angular velocity sensor includes a supporting substrate, a detecting portion, a displacement detecting portion, a first driving portion, and a second driving portion. The detecting portion is supported by the supporting substrate movably in at least a free direction. The displacement detecting portion detects a displacement of the detecting portion in the free direction. The first driving portion excites a first reference oscillation of at least a portion of the detecting portion so that a first Coriolis' force in the free direction is generated in response to an angular velocity about a first axis. The second driving portion excites a second reference oscillation of at least a portion of the detecting portion so that a second Coriolis' force in the free direction is generated in response to an angular velocity about a second axis.
