摘要： PURPOSE:To extend a lens smoothly by moving an outer cylinder in optical-axis directions by turning the outer cylinder around an optical axis. CONSTITUTION:The outer cylinder 2 for focusing is fitted coaxially and turnably around one end part of a main fixed lens barrel 1, and lenses L1-L3 for focusing are fitted to this outer cylinder 2. Further, a cam groove 3 is formed in the outer cylinder 2, which when turned around the optical axis, moves in an optical-axis direction under the guidance of a guide member 4 fitted in the cam groove 3. The guide member 4 is fitted turnably to a shaft 5 projected radially from the outer circumferential surface of the main lens barrel 1 and a specifying shaft 7 projected radially from the outer circumferential surface of the main lens barrel 1 is engaged with an arcuate long-sized hole 6 centering on the center of turning of the guide member 4, i.e. the axis of the shaft 5 to allow the guide member 4 to turn around the shaft 5 within the range of the long-sized hole 6, so that the outer cylinder 2 is moved finely in optical-axis directions by the turning of the guide member 4.

摘要： PURPOSE:To obtain a video camera having high portability, by deflecting about 180 deg. the optical axis of a photographing lens and setting the photographing lens and a photoelectric converting means in parallel to each other. CONSTITUTION:A photographing lens 12 is attached to a video camera main body 11, and the optical axis 13 of the lens 12 is deflected 90 deg. by a half mirror 14 incorporated into the main body 11. The axis 13 is then folded 90 deg. again by a surface reflecting mirror 16 after passing through a relay lens unit 15 and reaches an image pickup tube 17. In other words, the lens 12 and the tube 17 are set in parallel to each other. A rectangular prism, etc. can substitute the mirrors 14 and 16 as the optical axis deflecting means. In such a constitution, a large projection is excluded and therefore the camera case can be miniaturized. This realizes a video camera having high portability.
摘要翻译：目的：获得具有高便携性的摄像机，通过偏转大约180度。摄影镜头的光轴并且设置摄影镜头和光电转换装置彼此并联。构成：拍摄镜头12安装在摄像机主体11上，透镜12的光轴13偏转90度。通过并入主体11中的半透镜14将轴13折叠90度。再次通过表面反射镜16通过中继透镜单元15并到达图像拾取管17.换句话说，透镜12和管17彼此平行设置。矩形棱镜等可以将反射镜14和16替代为光轴偏转装置。在这种结构中，排除了大的投影，因此可以使相机外壳小型化。这实现了具有高便携性的摄像机。

摘要： PURPOSE:To zoom surely in the direction which a photographer intends and prevent a photographing miss, by displaying the direction of zooming by the first operation and performing the zooming operation by the second operation. CONSTITUTION:In case of zooming-in, when a tele-operation face 7b of an operation switch 7 is depressed softly, a notched part 11e and a ball 21 for click are engaged with each other, and a common point 11a and a contact 11b are made conductive, and a diode 19 for tele-display is lit to indicate preliminarily that the zooming operation is performed toward the tele-side. When the tele-operation face 7b is depressed more strongly, the notched part 11e gets over the ball 21 for click, and the common point 11a and contacts 11b and 11c are made conductive by a contact piece 11d. Then, a current is flowed to a DC motor 16 to drive a zoom lens barrel 24 in the direction of zooming-in. In case of zooming-back, the device is operated similarly by depression of a wide-operation face 7a.

摘要： PURPOSE:To reduce the number of worked cam grooves to one by clamping a rotatable eccentric pin as a guide pin and a stopper pin for specifying its angle of rotation coaxially and mutually. CONSTITUTION:Figures are a sectional and a plane figure of a principal part where the eccentric pin 3 and stopper pin 4 are clamped coaxially and mutually and one cam groove is worked. The eccentric pin 3 adjusted to infinite distance engages with the cam groove 1d and is clamped by a screw 7 on the same axis with the stopper pin 4 which specifies its angle of rotation. This sotpper pin 4 is longer than the external diameter of the eccentric pin 3 in a cam rotation direction, but short enough in a cam groove side face direction not to contact the cam groove side face by the eccentricity of the eccentric pin 3.

摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal projector by which a projected trapezoidal picture can be corrected while being moved vertically, a lens can be changed from a front surface without disassembling a set main body and an existing lens for movie theater, an anamorphic lens or other lenses can be attached. SOLUTION: A knob 17 at the upper part of the main body of the liquid crystal projector is turned right and left, then the lens is moved vertically. In the case of changing the lens, the lens is detached from the outer barrel part 9-2 of a lens holding part 9 by rotating an inner lens barrel 8 from the front surface of a main body box and unscrewing a screw. Then, a lens holding member is divided into three and an intermediate member is made to function as an adapter.

摘要： PROBLEM TO BE SOLVED: To provide an alignment device suitable to synthesize two lamps, as for a straight optical system in which a lamp bulb is fixed in alignment. SOLUTION: A concave reflection mirror 2, a light bulb 1, 1st and 2nd lens arrays 7 and 8, a rectangular or circular aperture grille 18 which is integrally formed in accordance with each cell of the lens arrays and an spherical correction lens 5 are held on a fixing table while being axially sifted at a fixed distance so as to constitute the straight optical system. Thus, such a aligning device is provided that prevents the alignment where undesired light component is taken in and that undesired light is previously cut, as for two-lamp optical illumination for reflecting light near the 2nd focus of the elliptic type concave mirror in order to add a slit plate.
