摘要： A light scanning apparatus makes a light beam scan along a main scanning direction on an effective scanning region which has a predetermined width. The apparatus comprises: a light source which emits the light beam; a deflector which includes an oscillation mirror which oscillates about an oscillatory axis which is orthogonal or approximately orthogonal to the main scanning direction, deflects the light beam emitted from the light source using the oscillation mirror, and makes the light beam scan a second scanning range which contains but extends beyond a first scanning range which corresponds to the effective scanning region; a detector which detects the scanning light beam which moves through a position which is outside the first scanning range but is within the second scanning range, and outputs a signal; and a controller which controls a mirror drive signal fed to the oscillation mirror based on the output signal from the detector and accordingly adjusts the amplitude of the oscillation mirror. In the apparatus above, the controller stops driving the oscillation mirror when confirming based on the output signal that the oscillation mirror is under abnormal control.

摘要： In an image forming apparatus including plural exposure units each deflecting a light beam from a light source by means of an oscillation mirror in resonant oscillations and scanning the deflected light beam on a latent image carrier thereby forming a latent image on the latent image carrier, every one of the exposure units assuredly attains an adequate amplitude of the oscillation mirror for ensuring the formation of images of high quality. More specifically, a CPU 101 retrieves resonant frequencies of individual deflectors previously stored in a memory. The CPU 101 calculates an average value of these resonant frequencies and applies a drive command to mirror drivers 1022 of the exposure units 6Y, 6M, 6C, 6K such as to drive all the deflectors into oscillations at the average value. Alternatively, a resonant-frequency adjusting section 653 makes adjustment to match the resonant frequencies of the individual deflectors substantially with a drive frequency. This ensures that all the oscillation mirrors attain adequate amplitudes.

摘要： As a scanning light beam which is scanning and traveling away from an effective image region moves passed the location of a sensor, a horizontal synchronizing signal Hsync is obtained as a first detection signal. A deflection mirror surface turns around, thereby reversing the direction in which the scanning light beam scans. This scanning light beam therefore scans an effective image region IR, and a latent image forming operation using this scanning light beam is controlled based on the horizontal synchronizing signal Hsync. Hence, there is a relatively long period of time (T4+T5) since the horizontal synchronizing signal Hsync is obtained until formation of a latent image starts in accordance with the signal Hsync. This secures sufficient time for control of the latent image forming operation based on the horizontal synchronizing signal Hsync, and hence, realizes the latent image forming operation as desired during the time T6.

摘要： A light scanning apparatus includes a deflector having an oscillation mirror that oscillates about an axis that is orthogonal to a main scanning direction. A detector detects a scanning light beam deflected by the oscillation mirror and moving in a scanning region. A controller adjusts the amplitude of the oscillation mirror based on a detection signal outputted from the detector, and stops driving the oscillation mirror when the detection signal is not outputted from the detector.
