Description of the Invention (22) The manufacturing method of the array 1 is described as a representative example. When the first lens array 1 is to be manufactured, first, a long rectangular sheet-like or plate-shaped resin molded product as shown in FIGS. 5 to 7 is manufactured. The resin molded product Γ has translucency and has approximately the same number as the plural number. Ben Zhao la is arranged side by side and looks like one piece. Accordingly, the resin-molded product worker has, for example, a plurality of first lenses 11 of ten rows arranged in the length direction of the resin-molded product 1_, a portion corresponding to the plurality of first support portions 10, a plurality of concave portions 14a, and, Plurality of recesses 13. The resin molded product Γ has outer peripheral edges 19a, 19b, 19c, and 19d surrounding a region where a plurality of first lenses U are formed. The thickness of these outer peripheral edges is set to be thicker than the region where the first lens 11 is formed. A band-shaped field 19e extending in the direction of the row of the first lenses' is provided between the fields corresponding to the i-th support portions 10, and the thickness of the band-shaped field 19e is set to be larger than that of the plurality of first lenses II. For thick size. The resin molded product Γ is manufactured, for example, as shown in Nos. 8 and 9 by using a steel mold 6.

Description of Invention (23) 6b. When the mold groove 65 of the steel mold 6 is filled with a translucent synthetic resin for molding, a resin molded product 1 can be obtained. Each of the through holes 62 of the auxiliary molds 6c and 6d can play the role of forming the outer peripheral surfaces 11c and lid of each of the i-th lens 11 shown in Figs. 3 and 4. When the resin molded product 丨 is compared with the first lens array 1 finally obtained, the overall size is large, and the mold groove 65 can be set to a larger volume. Therefore, when the molten resin is poured into the mold groove 65, the flowability of the molten resin in the mold groove 65 can be improved. As a result, each part of the resin molded product γ can be appropriately molded. In particular, the portions corresponding to the thick portions of the outer peripheral edges 19a, 19b, 19c, and 19d of the 'resin-molded product Γ' in the die groove 65 and the plurality of strip-shaped areas 19e become a large void portion. Therefore, the resin is melted. That is, these parts can flow smoothly and penetrate into the entire area in the mold groove 65. Regarding the supply direction of the resin in the die groove 65, for example, as indicated by the arrow Na in FIG. 10, it is preferable to take a direction extending along each convex portion 64. By adopting the above structure, the circulation of the resin can be prevented from being greatly hindered by each of the free-standing sections 64. After the resin molded product Γ is manufactured, a coating process is performed. For example, as shown in FIG. 11, 'this coating treatment is a resin molding, and it is immersed in a black coating liquid P. When the above method is adopted, the entire resin molded product 1 can be covered with a black paint. In the present invention, instead of the above method, there is a method in which a black ink is sprayed on the entire resin molded product 1 by using, for example, black jet print. At this time, it is also acceptable to let the above-mentioned ink accumulate in each of the recesses 14a. It can be seen that * In the order of the present invention, the method of covering the surface that defines each recess 1 利用 with a dark substance can also be used. A dark substance 311329 can also be used. ---- „---- Order --------- line f Please read the phonetic on the back?

After the black coating is completed, 'as shown in Figure 12, since In the coating material covering the resin molded product 1 ', the processing of removing the portions adhering to the first and second lens surfaces Ua, lib is performed. This processing must be performed by wiping the coating material p with a water-absorbing roller 80, for example, before the coating material p is dried and hardened. Since the first and second lens surfaces 11a and lib are relative to the surface i0a or the surface 10b of the first supporting portion 10, they have a step difference of the size si, and thus can pass through the first and second lenses. The paint p on the mirror surface Ua, lib is different from the paint p on the surface 10a, 10l) and is simply removed. As for the paint P, as shown in FIG. 13, it is not removed from the resin molded product]. Part of it can be left to dry and harden to be described later, and become the light-shielding film 15a, 5b, and coating film 14b described above. In the present invention, the method of replacing the above-mentioned coating can be adopted first in the i-th and second transparent After the mask is applied on the mirror surfaces 11a and 11b, a black coating is applied to the resin molded product 1 and then the masking methods on the first and second lens surfaces lia and lib are removed. Β Second, as shown in FIG. 14 'The resin molded product is divided as shown in the figure. This division operation is performed by cutting the resin molded product one by one or simultaneously through an imaginary line indicated by the symbol Nb-Nb in each of the band-shaped areas I9e. As for the cutting method, various methods such as machining of a cutter or laser processing can be used. Through the above-mentioned cutting operation, a plurality of first lens arrays 1 > first lens array 1 with a cut surface can be obtained. The side surface parts f, lg are not covered by the coating film. The side surface parts lf, lg can be applied with a black coating when necessary.

Thus, the first lens array [ The production efficiency is also high. As for the black coating corresponding to the components of the plural lens arrays, since the resin moldings are performed together, the production efficiency becomes higher. The second lens array can also be produced efficiently by the same method as described above. After the second and second lens arrays 1 and 2 are manufactured, the concave portions 13 and the convex portions 23 are fitted to each other, so that the lens descending unit U1 can be simply assembled. As described above, the manufacturing of the lens array unit u 1 is extremely easy. Therefore, its manufacturing cost can be reduced. The first and second lens arrays 2 and 2 can also be manufactured by a method different from the method described above, and their specific examples will be described with reference to FIGS. 5 to 8. To manufacture the first lens array 1, first, the resin molded product 1 shown in Figs. 15 and 16 is formed. In this resin molded product ", a plurality of recessed portions 14a have not been provided. Therefore, as the steel mold for molding the resin molded product, a steel mold 6A without a plurality of free portions corresponding to the plurality of concave portions 14a and having a simple structure can be used as shown in FIG. 17.

Description of the invention (26) 8l Korean-style sharp bed (not shown) mechanical processing device. When using a milling machine, multiple recesses 14a can be processed at the same time, which can improve the work efficiency. "It is best to pour the resin molded product 1 with cooling water" or immerse the resin molded product 1 in cooling water during processing. In the method, 'the temperature of the processed portion can be suppressed, and the first and second lens surfaces 11a, lib can be prevented from being deformed due to the increase in heat. When using machining,' compared with the use of a resin molding steel mold, the concave portion 14a is formed. The concave portion 14a can be processed into a thinner concave portion. If the concave portion can be formed into a thinner width, then the arrangement interval of the first lens 11 can also be set to a smaller width, and the resolution of the lens array unit U1 can be improved. And, the image formed by using the lens array unit U1 becomes bright and ideal. The processing means of each recess 14a can also be a laser processing device. The laser processing device preferably adopts an excimer laser ) Or carbon-oxygen laser, which can be used for photochemical processing. Here, the first chemical processing does not refer to the use of the thermal energy of the laser beam, but refers to the use of light The effect can be the level of molecular level, to release or destroy the material binding state of the processing object.

Description of the invention (2?)! 〇 A state in which the recessed portion 14a is formed in the entire length direction. In the present invention, the recessed portion 14a is formed as According to the above manufacturing method, it can be known from the above-mentioned manufacturing method that "when the body U of the first lens array" is intended to be manufactured ", a resin molded article having the same shape as the body connected to the plurality of bodies la is formed before forming it. The method of division is more efficient. However, the manufacturing method of the lens array unit of the present month is not limited to this. For example, it is also possible to form the body la in a single product by using a resin molding process using a steel mold. Second, let ’s The function of the lens array unit m is described with reference to FIGS. 21 and 22. As shown in FIG. 21, the lens array unit m is in the phase of the lens array 1 and the imaging object (a_b) at the starting point S. Face-to-face user. The light from the starting point s passes through each of the [lenses u, and then passes through the second lens 21 to reach the imaging point b. At this time, since it passes through the], 2, 3, and 4 lens surfaces 11a, 111? , 21 & '211), the light refraction effect can obtain about the same phenomenon as that of the serpentine lens seen in the previous technology of the Cellofok lens. Due to this phenomenon, an upright equal magnification image (a, -b,) of the object (a-b) at the starting point s can be formed at the imaging point R. The above phenomenon, in other words, has the following meaning. That is, the i-th lens surface 11a functions to form an inverted reduced image of an object. The inverted reduced image is formed near the second lens surface 11b, and further forward of the third lens surface 21a. In this way, the inverted and reduced image is enlarged and reversed by the action of the third and fourth lens surfaces 21a'2Ib. As a result, an upright image of the object is imaged on the imaging point R.

Invention Description (28) Arranged in a row, so the equal magnification of the object is formed in The linear area of the imaging point R. In the optical system shown in FIG. 21, even if the light emitted from the starting point s advances to the surface 10a of the first support portion 10, the light is applied by the light-shielding film 15a. The β is blocked so that only the light coming in through the first lens surface 11a in the first lens 11 is properly incident. In addition, the light shielding film 15a also plays a role in preventing the light from the starting point S from directly passing through the first direction from the thickness direction. The role of the support portion 10. The light-shielding film 15b plays a role of preventing unnecessary light from advancing from the portion other than the second lens surface 1b of the first lens array 1 to the second lens array 2. The plurality of light-shielding portions 14 The rays of light from one first lens 11 toward the other first lenses 11 adjacent to it are cut off and absorbed. Thus, the plurality of light shielding portions 14 can separate the plurality of first lenses 1 from each other. The crosstalk phenomenon of light rays is effectively prevented. In the lens array unit U1, since the plurality of concave portions 14a are respectively provided on the two surfaces 10a and 10b of the first support portion 10, even if the depth of each concave portion 14a is set to be shallower Size, the effect of sufficiently preventing the crosstalk phenomenon of light can still be obtained. "If the depth of each recessed portion 14a can be set to a relatively shallow size, when forming each recessed portion 14a by, for example, a resin molding process, it is used to perform the forming step. In the steel mold, the protruding size of the convex portion corresponding to each of the concave portions 14a can also be relatively reduced. "This can simplify the production of the steel mold. In addition, if the protruding size of the convex portion is made smaller, the The smooth flow of the resin in the mold cavity of the steel mold is favorable, and the incidence of defective products can be reduced when the resin molding of the body 1a is performed.

Therefore, in this lens array unit m, regardless of the first and second lens barriers 3 Whether 2 and 2 belong to synthetic resin products with translucency, the useless light for imaging can not make it reach the imaging point R, and can form a sharp portrait. In the above optical system, from the starting point s to the lens array The distance L1 to the unit and the distance L2 from the lens array unit ui to the junction point R are both controlled by the convex curvatures of the lens surfaces Ua, 11b, 21a, and 21b. Therefore, in this lens array unit U1, by changing the curvature of each lens surface (changing the steel mold for forming), the distances LI and L2 can be changed arbitrarily and easily. Since the lens array unit U1 sets the relationship between the lengths Sa and Sb of the first and second lenses 11 and 21 to the relationship of Sa > Sb, it can be obtained when the lengths of the first and second lenses 11 and 21 are equal to each other. Unavailable advantages. This point will be described with reference to FIG. 22. Fig. 22a is an explanatory diagram of the operation of the lens array unit U1 using the present invention, and Figs. 22b and 22c are explanatory diagrams of the operation of Comparative Examples 1 and 2 of the present invention.

In this way, the amount of light emitted from the fourth lens surface 21b is reduced, and the image (a'-b ') is darkened. In contrast, in the configuration of this embodiment shown in FIG. 22a, the “second lens 21” is set to be “shorter than the comparative example 1 in FIG. 22b”, so that the light traveling in the second lens 21 is easy.

Therefore, in the lens array unit U1 of the present embodiment, 'the amount of light emitted from the fourth lens surface 21b becomes larger', and the image of the imaging point R can be made brighter β '. Next, in Comparative Example 2 in FIG. 22c, Each of the first and second lenses 11 and 21 is set to a shorter size sb. In this configuration, the inverted reduced image (a ,, -b ") of the object (a-b) is imaged at a position (part indicated by the symbol ^^^) that is approximately a distance away from the first lens surface iu and equal to the size Sb. ). When the distance from the first lens surface 11a to the imaging point Nd of the inverted reduced image ^ -...) is short, the reduction magnification of the inverted reduced image becomes large, and the image becomes relatively small β, thus In order to enlarge the image to equal magnification, it is necessary to make the magnification of the image formed by the third and fourth lens surfaces 21 a and 21 b larger.

"The function of the optical device A2 is explained." In this optical device A2, when the light from the light source 73 is irradiated to the image reading field At La, the light reflected from the original g after passing through the divergent lens 8 reaches the lens array unit U2. In this way, the light passes through the first and second lens arrays 1 and 2 and the first and second lenses Π and 21 in 7 rows are arranged in a wide direction, and then focused on the light receiving element 74, and the image of the original G is also superimposed on The light receiving element 74 is imaged. Therefore, the image formed on the light receiving element 74 becomes brighter when compared with a case where a lens array unit in which only one row of the first and second lenses 11, 21 is provided is used. However, when the first and second lenses 11 and 21 of the seventh row are used for imaging as described above, the incident angles of the light rays to the first lens face 11a of the seventh row are different from each other. Therefore, if the first and second lenses are 11, 21, all the sharp surfaces are unified in the same shape. 'It is often difficult to distinguish the light that advances from the field of image reading when it is correctly focused on the light receiving element 74. Therefore, as a means to eliminate the above problems, for example, the shapes of the first, second, third, and fourth mirror surfaces Ua, lib, 21a, and 21b of each of the first row K to the seventh row N7 may be different. Of the structure. As shown in detail in Fig. 35, the light rays starting from the image reading area La are diverged by the diverging lens 8 to an appropriate angle before reaching the lens array unit U5. Therefore, the light beam focused by the lens array unit U5 on the light receiving element 74, that is, in a region between the image reading area La and the divergent lens 8 becomes a state where the enlarged angle 0 is relatively narrow.

Description of the invention (39) The depth of focus of the mirror array unit U5 becomes deeper, even if the original is transparent For example, the board 70 floats up, and the image on the light receiving element 74 is formed, and the focus blur is still not easy to occur. The diverging lens 8 is not directed to the length direction of the second and second lens arrays 2 and 34 (and 34th and third). The cross section or orthogonal direction shown in Fig. 35) causes the light to diverge. Therefore, the length direction of the first and second lens arrays 1 and 2 is based on the same principle as the lens array units U1 to U4 of the above embodiment, and Form an upright equal magnification image of the original G. When the daylight image of the original is to be imaged based on the lens array unit U5, the crosstalk phenomenon of light between the first lenses can be appropriately prevented by the coating film 16a of the light shielding portion 16.

Description of the invention (47) The imaged part of the image displayed on the screen 32 of each liquid crystal display 3. The color consideration Is 5 The basic structure is also the same as that of a color filter used in a color liquid crystal display. That is, as shown in FIG. 50, the color filter 5 has color filter sections 50 of R, G, and B colors arranged regularly. In the color filter 5, the three color filter sections 50 of r, g, and B become 1 pixel. "In the liquid crystal panel of each liquid crystal display 3," the dots and filters for expressing the colors of R, G, and B are displayed. The color filter portions 50 of the respective colors R and G′B in the color device 5 are in a positional relationship corresponding to each other. Although the surface 51 'on the light exit surface 51 of the color filter 5 opposite to the surface 52 facing the concave lens 4 is not shown in the figure, it is a gently concave or convex curved surface. Next, the function of the optical device A5 will be described. First, as shown in Fig. 49, the respective screens 32 of the plurality of liquid crystal displays 3 are displayed as desired images (a-b) and (c-d). In this way, the light emitted from the lighting device 31 and transmitted through each liquid crystal panel passes through the plurality of lens array units U8 and the concave lens 4. At this time, the plurality of lens array units U8 are to form the upright equal-magnification images of the portraits (a-b) and (c-d). On the other hand, since the concave lens 4 ′ is present at the rear stage, it is therefore on the surface of the color filter 5 The erect enlarged images (a '-> b') and (c'-d1) are formed above. The screens 32 of the plurality of liquid crystal displays 3 are separated from each other by an appropriate distance L3. However, since the images of these screens 32 have been expanded 'so', the images (a,-&b;) and (c (-d ') can be connected to each other on the surface of the color filter 5. When the color filter 5 When daylight images (a'-b,) and (c, -d,) are imaged, the color filter portions 50 of each of R, G, and B will show a brightness of 3 corresponding to the amount of light received.

Description of the invention (48) The direction of the side surface 51 is observed with the naked eye. When it is set to 'as described above, because it is different from when using a white screen, it does not use white as the underlying color to express various colors, Therefore, 'for example, the reproducibility of black or similar colors becomes better', and the contrast of the imaged image can be improved. Moreover, since the surface 51 of the color filter 5 has a crossbow shape, the viewing angle also becomes large. In the present invention, a general white screen can be used instead of the color filter 5 »In addition, 'CRT or other devices can also be used as an image display to replace the liquid crystal display 3. Furthermore,' in the present invention, a convex lens can also be used instead The concave lens 4 'is used to reduce and project the images displayed on the screens of the multiple image displays onto the screen. In this case, the images on the screens of the image displays can still be connected to form a series of images and projected on the screen. Of course, in this book In the invention, in addition to the method of using a plurality of portrait displays, an image displayed on a screen of one portrait display may be enlarged and projected on a screen.
