摘要： PURPOSE:To produce bar lenses arranged zigzag by pressing an adhesive gumlike material to the bar lenses on a grooved block. CONSTITUTION:Plural pieces of bar lenses 3 are placed in the groove parts of a grooved block 10 of which the grooves are set with disposition intervals with good accuracy. The positions thereof are adjusted with an end face position adjusting plate 11. A weight plate 12 provided with a bar lens holding plate 13 coated with an adhesive gumlike material in its hollowed part is placed on these bar lenses 3 and is pressed. After the adhesive gumlike material has dried, the block 10 and the plate 12 are removed, whereby the bar lens holding plates 13, 13' adhered with the bar lenses are obtained. The two plates 13, 13' are coupled in such a manner that the lenses 3, 3' are arranged zigzag with deviations mutually of each half pitch. At the time of coupling these, a light shielding type gumlike material is filled between the lenses in order to prevent stray light.

摘要： PURPOSE:To improve optical setting precision by arraying plural bar lenses of prescribed length zigzag. CONSTITUTION:Element lens systems in the optical axis direction that project one area of a body upon a prescribed area on an image surface are arrayed in the prescribed direction in the surface perpendicular to the optical axis. Every element lens system consists of bar lenses 11 whose length in the optical axis direction is longer than the effective diameter and is provided with light absorbing layer 15 that forms normal image 14 of nonmagnification on the final image surface after forming intermediate image 13 at the bar-lens intermediate part and control prescribed light intensity distribution on the final image surface at the bar-lens outer circumference part. Further, bar lenses 11 are position-controlled by lens holders 18a and 18b with grooves and arrayed zigzag.

摘要： PURPOSE:To make it possible to record and reproduce information accurately without erroneous input of information by providing a guide material, which guides a recording medium along a fixed locus, and elastic material parallel with the material above, and an axis material, etc., to cause the recording medium to advance along the fixed locus. CONSTITUTION:Metallic roller rim 2 uniting with feeding roller axis 1 is a conical trapezoid. Soft rubber roller 3 is printed on rim 2. Magnetic card 4 of a recording medium is pressed by roller 3 and is fed in guide groove 6 by the contact frictional force. Guide groove walls 5 are in both sides of guide groove 6, and one of them is a reference face (5' is a reference face in the figure). Recording and reproducing are performed by magnetic head 8, and they are performed accurately without generation of track slippage of magnetic card 4. Further, the constitution is easy to produce and assemble.

摘要： PURPOSE:To obtain a compact ommateal projecting device by arranging a plurality of cylindrical bar lenses generating an erected unmagnification image on a plane plate and by fixing them by the adhesive admixed with a black pigment to form the first stage array and by arranging and fixing the second stage and following stages zigzag with the shift of every interval corresponding to the half of the bar lens. CONSTITUTION:The inverted intermediate image of object 12 is formed on the center image surface of cylindrical bar lens 11 to focus erected unmagnification image 14 onto the projection face. The light off from the optical axis is absorbed by light absorbing layer 15, and the solid angle of the light flux converged to the image surface becomes smaller according as it is further from the optical axis. These bar lenses 11 are arranged in parallel on the groove, where the adhesive admixed with a black pigment is applied to groove plate 18 previously, and are fixed, and after that, the second stage bar lenses 11 (shown by the dotted line) are fixed with the shift of the interval corresponding to the half of the bar lens by the same adhesive, and thus, plural stages are arranged zigzag. Glass and other resins can be used for bar lenses 11. As a result, a compact ommateal projecting device is obtained.

摘要： PURPOSE:To make optical adjustment easy and stabilize optical performance by forming the element lens system in a projector comprising a compound eye optical system into the only transmission type lens of an optical axis direction length longer than the lens effective diameter. CONSTITUTION:A lens 18 has a length longer in the optical axis direction than the lens effective diameter. An object 19 is imaged as an inverted intermediate image 20 in the intermediate part in the optical axis direction of the lens 18 and is finally formed as an erecting unmagnification image 21 on the projecting plane. An absorbing layer 22 is set on the outer side of the lens 18 and the rays beyond the lens effective diameter region are annihilated by the absorbing layer 22. Hereupon, the intensity distribution of this element lens system becomes a Gauss distribution and it is possible to make nearly a uniform intensity distribution on the image plane by arraying a plurality of these in more than one row at an equal space within the plane normal to the optical axis. It is desirable that the lens 18 satisfies condition formulas 1, 2, 3. In this way, the optical adjustment may be made easy and the optical performance is stabilized.

摘要： PURPOSE:To obtain a required surface accuracy in a short time by a method wherein a glass fiber rod rotating in a low speed is ground by a grind stone rotating in a high speed when forming a bar lens having an optical axis length longer than an effective diameter of a copier, etc. CONSTITUTION:A glass fiber rod 1 is rotated in a low speed preventing it from a swing by means of a motor 6 and a working grind stone 4 is rotated at a high speed by means of a motor 7, and further, an arrow A direction feeding is given and a grinding is performed upto a given position. In this way, after a spherical working on a surface is finished, a spherical working onto another spherical face is performed in the same manner. At this time, a collect chuck 3 and the working grind stone 4 are supported by high precision bearings 2, 5, respectively. In this way, a spherical face of high accuracy can be obtained in a very short time.
