摘要:
A method of manufacturing oscillator devices each having an oscillator and a resilient supporting member for supporting the oscillator for oscillatory motion, includes a step of processing one and the same substrate to form oscillators and resilient supporting members of oscillator devices so that oscillators of adjacent oscillator devices are connected to each other, a step of forming or placing a magnetic material so that it extends across the connected oscillators of the adjacent oscillator devices, and a step of simultaneously cutting and separating the connected oscillators and the magnetic material formed or placed to extend across the connected oscillators, whereby oscillator devices such as oscillatory type actuators having good reliability and performance evenness can be manufactured with a good productivity.

The optical deflector includes a deflector, a vibration detector, a driving signal generator, a modulation timing signal generator, and a deflection detector. The deflector has a vibrational system having a movable body with a light deflecting member, and deflects light from a light source by the movable body. The vibration detector detects the vibration condition of the vibrational system of the deflector. 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.

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.
