Abstract

PURPOSE:To miniaturize the device, by constituting the imaging lens for scanning with a single lens. CONSTITUTION:A scanning lens 3 for imaging the luminous flux from a light source 1 being deflected by a deflector 2 on the plane being scanned 4' is composed of a single lens. When a spherical single lens is used for the scanning lens 3, the turning characteristic of the deflector 2 is sinusoidal vibratory turning. By selecting the sinusoidal vibratory amplitude, the plane being scanned 4' may be spot-scanned at equal intervals of distance with respect to the modulation signals at equal intervals of time. When an aspherical single lens is used, on the other hand, no restrictions are applied to the turning characteristic of the deflector 2, and the plane being scanned 4' is spot-scanned at equal intervals of distance. Further, positively utilizing the Petzval's sum of the scanning lens, the flat plane being scanned is effectively used. Thus, using a single lens for the scanning lens 3, the device may be miniaturized, and the plane being scanned 4' may be scanned at constant speed.
