    • A camera has barrier supported by a rail block attached to the body of the camera and movable from a fully closed position where the barrier entirely covers the front of an imaging lens to a fully opened position where the barrier is fully retracted clear of the front of the imaging lens. At its fully closed position and fully opened position, the barrier clicks when a ball is pressed into contact with a cam formed on the rear surface of the barrier. Projection of the ball is restrained by a slip-off prevention portion of the rail block so that the barrier is not subjected to an excessive urging force. In the camera, the barrier is not subjected to an unnecessarily large urging force and is less likely to lift away from the camera. The advantage is particularly great if the barrier in use is narrower than the outer diameter of a lens barrel.
    • 相机具有由连接到照相机主体的轨道块支撑的障碍物,并且可以从完全关闭的位置移动,其中障碍物完全覆盖成像透镜的前部到完全打开位置,在完全打开的位置, 成像镜头。 在其完全关闭位置和完全打开位置时,当球与形成在障碍物的后表面上的凸轮按压接触时,障碍物咔嗒一声。 球的投射由轨道块的防滑部分约束,使得挡板不会受到过度的推动力。 在相机中,屏障不会受到不必要的大的推动力,并且不太可能离开相机。 如果使用的屏障比透镜镜筒的外径窄,则该优点特别大。

    • An object of this invention is to provide a method for processing signals for an optical disc device and an optical disc device for immediately determining the on-track state of a main beam light impinging on an optical disc including land areas on which information is recorded, said optical disc being track-formatted to have a double spiral structure. In recording or reproducing information on or from the land areas while track-controlling a first reflected light (MB) based on a second reflect light (SB1) and a third reflect light (SB2), the phases of a sum signal (SUM) and a difference signal (DIFF) between a first push-pull signal (PP1) obtained from an output from a first split photo conductor (21) and a second push-pull signal (PP2) obtained from an output from a second split photo conductor (23) are compared to determine from the mutual phase relationship which land area is providing the first reflected light (MB).
