    • The present invention provides a method of designing a post-objective type optical scanner having an optical deflector composed of cylindrical or spherical reflecting surfaces for deflecting a converged light beam from a condensing lens by reflecting the converged light beam as it rotates, and a compensating lens located in an optical path between the optical deflector and a scanning surface for converging the deflected light beam from the optical deflector to a point on the scanning surface, of which power in the sub-scanning direction varies with a length from the center thereof in the scanning direction. The method is characterized in that a scanning speed(S) defined by a scanning width on a scanning surface per an angle unit of rotation of the optical deflector is selected by exploiting a characteristic that a maximum curvature of field in the scanning direction drops to a minimum value in a certain range predetermined by a length from a point of deflection of the optical deflector to the scanning surface(L) based on a correlation between the scanning speed and the maximum curvature of field in the scanning direction. In the method, offset of the f.multidot..theta. characteristic is maintained to be within .+-.0.5%, and the certain range is expressed as ##EQU1##
    • 本发明提供了一种设计具有由圆柱形或球面反射表面组成的光学偏转器的后置物镜型光学扫描器的方法,用于通过在会聚光束旋转时反射会聚光束来使会聚光束从会聚透镜偏转;以及补偿透镜 位于光学偏转器与扫描表面之间的光路中,用于将来自光学偏转器的偏转光束会聚到扫描表面上的一个点,其中副扫描方向上的功率随着其中心的长度而变化 扫描方向。 该方法的特征在于,通过利用扫描方向的最大曲率下降到一个特性的特性来选择通过光偏转器的每个角度旋转单位在扫描表面上的扫描宽度所限定的扫描速度(S) 基于扫描速度和扫描方向上的最大曲率之间的相关性,在从光学偏转器的偏转点到扫描面(L)的长度预定的一定范围内的最小值。 在该方法中,将fxθ特性的偏移保持在±0.5%以内,并且将该范围表示为

    • A connector assembly has a first connector, a second connector matable with the first connector along a mating direction, a mating assistance mechanism, a mating maintenance mechanism, and a detection mechanism. The mating maintenance mechanism includes a stopper, an engagement portion and an elastic support. The engagement portion is configured to be engaged with the stopper in a mating state of the first connector and the second connector so as to maintain the mating state. The detection mechanism is operable to detect the mating state and includes a short-circuit member and first and second terminals having first and second contacting sections, respectively, extending along the mating direction. The short-circuit member is arranged to establish a short circuit between the first terminal and the second terminal in the mating state.
