    摘要： The present invention is directed to improve prior art zoom lens systems that have groups of lens pieces moved within a lens barrel for the zooming and the focusing and to provide an improved zoom lens system that is simplified and robust in configuration so as to withstand malfunctions well and is capable of effectively and assuredly eliminating stray light. The zoom lens system comprises a first cam barrel rotating about the optical axis and a second cam barrel located inside the first cam barrel in cam-linkage with the same, and the zoom lens system is characterized in that the second cam barrel has openings to let light beams pass through, and that a light-shielding plate like an iris diaphragm is supported by the second cam barrel in position closer to the photographed subject in the second cam barrel so as to shield the light beams that come in from the openings in the second cam barrel after going out of the openings in the second cam barrel and then being reflected from an inner surface of the first cam barrel.

    摘要翻译： 本发明旨在改进现有技术的变焦透镜系统，其具有在透镜镜筒内移动的用于变焦和聚焦的一组透镜片，并且提供在构造上被简化并且坚固的改进的变焦镜头系统，以便能够良好地承受故障 并能有效，可靠地消除杂散光。 所述变焦透镜系统包括围绕所述光轴旋转的第一凸轮筒和位于与所述第一凸轮筒内的所述第一凸轮筒内的第二凸轮筒，并且所述变焦透镜系统的特征在于，所述第二凸轮筒具有开口以允许 光束通过，并且像虹膜光阑这样的遮光板由第二凸轮筒支撑在更接近第二凸轮筒中被拍摄对象的位置上，以便屏蔽来自第二凸轮筒中的开口的光束 第二凸轮筒从第二凸轮筒中的开口出来，然后从第一凸轮筒的内表面反射。

    摘要： Each of slave recorders includes a rotary drum, heads mounted on the rotary drum at positions spaced from a phase reference position on the rotary drum by different angular intervals respectively, and an arrangement for selecting at least one from the heads as an active head in accordance with a designated recording mode. Non-delayed stream data are delayed by a delay time interval to form delayed stream data. A distributor operates for distributing the delayed stream data to the slave recorders. Each of the slave recorders records the delayed stream data on a slave recording medium by the active head. The delay time interval corresponds to the angular interval between the phase reference position and the position of the active head.
