| PURPOSE: To reduce the size of a space required between a light source and a surface to be irradiated for required elargement by providing a mirror means returning reflected light from a beam splitting means performing the partial reflection and partial transmission of an incident light beam and a louver means transmitting the light within the limited range of an incident angle. CONSTITUTION: This device is provided with the mirror means 4 returning the reflected light from the beam splitting means 2 performing the partial reflection and the partial transmission of the incident light beam, and the louver means 3 transmitting the light within the limited range of the incident angle. In this case, the means 3 absorbs the light having the incident angle in terms of a normal with respect to the means 2 in a range other that the previously specified limited range, so that the influence of a secondary video produced by the unnecessary light beam from the means 2 is reduced by the means 3. The thickness of an entire display unit is further reduced by the reflection of the incident light beam by means of a mirror before the incident light beam enters the beam splitter.

| PURPOSE: To properly maintain the image-formation characteristics of the titled optical system and image-formation characteristics of a pupil by a method wherein an optical compensating device, with which the length of optical path will substantially be maintained even when the position between optical elements makes a change, is arranged in the optical path on a image-formation optical system. CONSTITUTION: The optical system is composed of an object plane 0, an image- formation plane I, an objective lens L 10 and an image-formation lens L 11. The relative position of said two lenses is to be changeable and the distance l of both lenses are also to be changeable. An optical path converter C consists of a mirror M 5, moving mirrors M 6 and M 7, a fixed mirror M 8 and a field stop D. Pertaining to the change Δl of the distance l, the mirrors M 6 and M 7 are moved as far as to Δl/2 to the direction shown by an arrow. At this time, as the length of optical path is extended as far as to Δl, the length of optical path is maintained constant in spite of the variation of interval l.

| 77 | Light irradiating device | JP8661282 | 1982-05-24 | JPS58203410A | 1983-11-26 | WAKABAYASHI AKIO |
| PURPOSE:To reduce the number of reflective mirrors required for changing the optical path in a device when an object irradiating part is rotated and turned upward and downward, by detecting the deviation of an incident light to control the rotation of a movable plane mirror. CONSTITUTION:A plane mirror 34 reflects a light incident vertically from below toward the center point of the surface of a movable plane mirror 37 at an angle alpha to the horizontal line without being affected by turning of a turning shaft 6. An attaching angle theta of the perpendicular of the movable plane mirror 37 to the incident light is adjusted in accordance with upward and downward turning of an object irradiating part 10, and the light is made incident to the movable plane mirror 37 so that the reflected light coincides with the axial line of the object irradiating part 10. In this case, when the angle of elevation of the object irradiating part 10 to the horizontal line is denoted as beta and the angle of the perpendicular of the movable plane mirror 37 to the incident light is denoted as theta, the movable plane mirror 37 is so adjusted that the angle of incidence and the angle of reflection to the perpendicular of the movable plane mirror 37 are equal to each other, and theta=alpha+beta/2 is obtained. The object irradiating part 10 is indicated by solid lines when it is in the horizontal position, and it is indicated by two- dot broken lines when it is in the vertical position. When the object irradiating part 10 is turned at the angle beta, the rotation quantity of the perpendicular of the movable plane mirror 37 is beta/2, and therefore, the angular speed of elevation is decelerated to 1/2 to rotate the movable plane mirror 37 in the same direction. | ||||||

| PURPOSE:To reflect a video symmetrically on a mirror surface by placing a sheet of mirror on a straight line and bending the video surface at a right angle or roughly a right angle to the inner side. CONSTITUTION:The entire body 1 of a plane mirror is bent at a right angle by a folding line 2 and is constituted of bent mirrors 3, 4. Two sheets of the mirrors 3, 4 are bent roughly at 90 deg. but there may be 1-2 deg. error. The video that reflects on such plane mirror 1 is such that the right hand 5 appears like the right hand on the surface of the mirror 3 and the left hand like the left hand on the surface of the mirror 4. Therefore if the right hand is moved, the right hand viewed on the left side of the mirror surface moves and if the left hand is moved, the hand viewed on the right side of the mirror surface moves. | ||||||
| 79 | Video rotation preventing device | JP19488981 | 1981-12-03 | JPS5895705A | 1983-06-07 | SAKATA FUMIO |
| PURPOSE:To constitute a titled device so that a video by rotation of a reflector is not rotated easily, by combining a picture inverting device, when observing the whole circumference without rotating a camera. CONSTITUTION:An optical path is inverted up and down by a picture inverting device 2, and as for a target T as indicated with an arrow, an arrow image T' in the upper direction is obtained by a TV camera 4. In relation of a position where a reflector 1 has been rotated by 180 deg., the inverting device 2 is rotated by 90 deg., and the optical path is inverted as to the right and left, is not inverted up and down, travels straight, and becomes an upward arrow T' in the TV camera image pickup tube 4. That is to say, in case when the reflector has been rotated by 2theta to Y2 from the axis Y, the picture inverting device 2 is rotated by theta. Also, the up-and-down axis Y of the picture inverting device 2 is always inclined by theta against both the axis Y and the axis Y2 , therefore, the target T on the aixs Y2 is always inverted by the picture inverting device 2 and is positioned on the axis Y. | ||||||
