    • An image forming apparatus and a method of controlling turn-on of light source used therefor are capable of conducting stable image forming operation and maintaining high effective scanning rate while switching the rotation control of the polygonal motor between the internal control by the internal encoder of the motor and the external control by the horizontal synchronous signal outside of the motor. With the apparatus and method, the period of detecting the timing of start of the fast scanning (referred to as SOS period) is T when the driving motor rotates at a predetermined number of revolutions. T becomes shorter by T2 due to the switching from the internal control to the external control. During the shift from the internal control to the external control, the light source is turned on so that the period T1 from turning-on the light source for detecting the SOS timing to the detection of the SOS signal becomes longer than T2. Thereby, turning-on of the light source is surely conducted earlier than the SOS signal detection timing when the rotational control is switched from the internal control to the external control.
    • 一种图像形成装置和控制其使用的光源的接通方法能够进行稳定的图像形成操作并且保持高的有效扫描速率,同时通过内部编码器的内部控制切换多边形电动机的旋转控制 电机和外部控制由电机外的水平同步信号。 利用该装置和方法,当驱动电机以预定转数旋转时,检测快速扫描开始时间(称为SOS周期)的周期为T。 由于从内部控制切换到外部控制,T由于T2变短。 在从内部控制转移到外部控制的过程中,光源被接通,使得从开启用于检测SOS定时的光源到SOS信号的检测的周期T1变得比T2长。 因此,当旋转控制从内部控制切换到外部控制时,光源的接通可靠地比SOS信号检测定时早。

    • A light beam reflected from an ocular fundus is split into a pair of right and left light beams by a two-aperture stop disposed in a position conjugate with an anterior ocular segment of an eye to be examined. The pair of right and left ocular fundus images having a parallax is formed as intermediate images from the split light beams at the position of a photographic mask. The optical path of the pair of ocular fundus images formed as intermediate images is split by a pair of optical path splitting lenses disposed in a position substantially conjugate with the two-aperture stop. One ocular fundus image is re-formed on half of an imaging plane of an imaging element, and the other ocular fundus image is reformed separately on the other half of the imaging plane. With such a structure, two ocular fundus images for three dimensional viewing can be efficiently obtained without using a prism for splitting the optical path.
    • 从眼底反射的光束通过设置在与待检查的眼睛的眼前段共轭的位置的双孔径光阑分成一对左右光束。 具有视差的一对右眼和左眼眼底图像被形成为在照相掩模的位置处的分离光束的中间图像。 形成为中间图像的一对眼底图像的光路被设置在与两孔径光阑大致共轭的位置的一对光路分离透镜分开。 在成像元件的成像平面的一半上重新形成一个眼底图像,另一个眼底图像在成像平面的另一半上单独重构。 利用这种结构,可以有效地获得用于三维观察的两个眼底图像而不使用用于分割光路的棱镜。

    • A boat propulsion system includes a power source, a propulsion section, a shift position switching mechanism arranged to switch among a first shift position, a second shift position, and a neutral position, a gear ratio switching mechanism, an actuator, and a control section. When switching is to be performed from the neutral position to the first shift position and the high-speed gear ratio, the control section is arranged to cause the actuator to, maintain the low-speed gear ratio, switch to the first shift position, and then establish the high-speed gear ratio when the current gear ratio of the gear ratio switching mechanism is the low-speed gear ratio, and cause the actuator to establish the low-speed gear ratio before switching to the first shift position, switch to the first shift position, and then establish the high-speed gear ratio when the current gear ratio of the gear ratio switching mechanism is the high-speed gear ratio. This arrangement improves the durability of a power source and a power transmission mechanism in a boat propulsion system including an electronically controlled shift mechanism.
