    • A video reproduction apparatus includes a video player 3 which reproduces a video signal, a V-chip signal for restricting a display of a specific image being added to the video signal; a video processing circuit 5 which processes the video signal from the video player 3; a CRT 7 which displays the video signal that is processed by the video processing circuit 5; a control section 10 which reads out the V-chip signal and judges whether a screen is to be blocked or not; and a memory 11 which stores a result of the judgment. When a mode is transferred to a special play mode, a judgment result which immediately precedes the mode transfer is read out from the memory 11. If the judgment result is that the blocking is to be blocked, the screen of the CRT 7 is set to a blocked state.
    • 视频再现装置包括再现视频信号的视频播放器3,用于限制添加到视频信号的特定图像的显示的V芯片信号; 视频处理电路5,处理来自视频播放器3的视频信号; 显示由视频处理电路5处理的视频信号的CRT7; 控制部分10,读出V-chip信号并判断是否屏蔽屏幕; 以及存储判定结果的存储器11。 当将模式转移到特殊播放模式时,从存储器11读出紧接在模式传送之前的判断结果。如果判断结果是要阻挡,则将CRT7的屏幕设置为 封锁状态。

    • A lens barrier device 10 includes a pair of lens barrier members 12, 12 having a pair of toggle-lever engagement bosses 12e, 12e, a ring 14 having a pair of recesses 14d, 14d formed on its outer circumferential part, a pair of toggle levers 15, 15 having a pair of triangular cam part 15d, 15d and a base frame 17 supporting the toggle levers 15, 15, and a pair of torsion springs 16, 16 engaged with the toggle levers 15, 15 and the base frame 17. In assembling, the toggle-lever engagement bosses 12e, 12e are freely fitted into the recesses 14d, 14d, respectively. With forward-reverse rotating of the ring 14, by allowing the toggle-lever engagement bosses 12e, 12e to slide along the triangular cam part 15d, 15d while pressing the bosses 12e, 12e through respective ends of the recesses 14d, 14d, the pair of lens barrier members 12, 12 are held in their closed or opened condition by the toggle levers 15, 15 and the torsion springs 16, 16.
    • 透镜屏障装置10包括一对具有一对肘杆接合凸起部12e,12e的透镜阻挡部件12,12,在其外周部形成有一对凹部14d,14d的环14, 具有一对三角形凸轮部分15d,15d和支撑肘节杆15,15的底座17以及与肘节杆15,15和基座17接合的一对扭力弹簧16,16的杠杆15,15。 在组装时,肘节杆接合凸台12e,12e分别自由地装配到凹槽14d,14d中。 通过环14的正向反转,通过使肘杆接合凸台12e,12e沿着三角形凸轮部15d,15d滑动,同时通过凹部14d,14d的各个端部按压凸台12e,12e,该对 透镜屏障部件12,12由肘节杆15,15和扭转弹簧16,16保持在其闭合或打开状态。
