Description of the Invention (1) [Technical Field] The present invention relates to the image sensor used for reading the original image and the transparent cover for the image sensor. [Background Art] An example of an image sensor is a close-type image sensor. The compact image sensor includes an outer case, a transparent cover mounted on the outer case, a light source, a lens array composed of a plurality of optical lenses, and a plurality of light receiving elements. When reading an image, the original is placed on the transparent cover, and the light source illuminates the transparent cover from the inside of the case '. In the above-mentioned waste type image sensor, the light emitted from the light source irradiates the original arranged on the transparent cover, and the irradiation range includes a line-shaped image reading area of the original. The light emitted from the image reading area is focused by the lens array, and the image of the original is imaged on the plurality of light receiving elements. Thereby, the above-mentioned plurality of light-receiving elements output an image signal corresponding to the output level of the light-receiving amount. The transparent cover mounted on the outer box has a function of blocking the outer box, preventing dust and the like from penetrating the inside, and guiding the original. In addition, the transparent cover also regulates the distance between the original and the lens array so that the image of the original can be appropriately imaged on the plurality of light receiving elements. Conventionally, this transparent cover has been used: those made entirely of glass; those made entirely of synthetic resin; and the like. Therefore, the conventional image sensor has the following defects. When using a transparent cover made of glass as a whole, when an impact force is applied to the image sensor, the transparent cover is easy to break, and its fragments are also easy.

Description of the Invention (Scattered everywhere. Especially when using the image sensor as a palm-type scanner (like)) 'Users may miss their hands to make the image sensing Device fell to the ground, so 'the above-mentioned deficiency will appear profound. On the other hand, if a transparent cover made of synthetic resin as a whole is used, its impact resistance will be greatly improved compared to glass makers, and cracks will not easily occur. However, the surface of the synthetic resin is lower than that of the glass, and the surface is easily damaged. For example, contact with platen (platen), or dust adhered to the surface, the surface is easy to be injured, which adversely affects the transparency (transmittance) of the transparent cover. Therefore, the surface flaw of the transparent cover is read. Due to the distortion of the image, the quality of the read image is degraded. In the past, in order to eliminate this defect, a groove was provided on the surface of the transparent cover made of the synthetic resin, and the image was read by the groove. If used, In the transparent cover with a groove, even if, for example, the platen roller is positioned opposite to the groove, the dust paper roller does not contact the transparent cover. Therefore, the surface of the transparent cover is easily injured due to the contact with the paper roller. However, the transparent cover with the grooves as described above, when the manuscript is pushed by the platen roller, because the front end of the original is stuck in the grooves, etc., the original paper is easy to jam and cannot be advanced. The problem exists. Moreover, the transparent cover with the grooves as described above also makes it easy for dust to accumulate in the grooves. When there is dust in the grooves, it will spread to transparency. The light transmittance of the four grooves is one of the reasons for the obstacle to the reading function of the original image. On the other hand, the image sensor is preferably configured to adjust the output level of the read image.

Invention Description (3) It is a method of "white level adjustment" or only "density adjustment". According to this method, the image of the original is implemented Before the reading process, first perform the reading process on the surface of the white platen roller opposite to the transparent cover to obtain the image signal of the white portrait. Second, determine whether the output level of the day image signal is appropriate. If 'this The output level is not appropriate, that is, according to the output level, adjust the light source driving voltage or the light receiving sensitivity of the plurality of light receiving elements' until the output level of the day image signal of the white image becomes a predetermined level "and use led Composition The light output of a light source is controlled by, for example, temperature. In addition, the sensitivity of each light receiving element that is a semiconductor product is also affected by the surrounding temperature. The output level adjustment for white portraits using the above methods can be based on Conditions suitable for actual use conditions, that is, implemented according to the actual use temperature. Thus, the image reading process is performed at an output level that appropriately corresponds to the actual use temperature, and thus the reading of the original can be obtained faithfully However, in the past, for example, when an image sensor was used for a palm-type scanner, it was not equipped with a platen roller, so it was not possible to adjust the output level using the white platen roller as described above. The conventional day image sensor still has the above-mentioned shortcomings at this point. [Disclosure of the Invention] Therefore, "the purpose of the present invention is to provide a non-missing original document jam, etc." to improve the impact resistance of the transparent cover and make the image Obstacles to reading, that is, damage to the surface of the transparent cover, are unlikely to occur, and image reading processing can be performed appropriately Like sensors.

As a result, the deterioration of the quality of the daylight image caused by the surface damage of the transparent cover can be eliminated, or at least reduced. The main body of the 2nd transparent cover, the cover body is made of synthetic wax, and the glass component is only used in a small part. Therefore, the impact resistance of the cover body can be improved. It is not easy to cause cracks and other damage. At the same time, Light weight of day image sensor can be achieved. Therefore, the image sensor of the present invention is particularly suitable for being mounted on a palm-type scanner which is desired to be lightweight. It is preferable that the transparent cover body has a groove 'corresponding to the day image reading area to accommodate the transparent glass member in the groove. It is preferable that the groove is formed so as to penetrate the transparent cover. In the image sensor having the above-mentioned configuration, since the glass member is in a state protected by the cover body ', not only the cover body is not easily broken, but the glass member is also not easily broken.

Therefore, when an image reading process is performed using an image reading device equipped with the image sensor of the present invention, it is possible to prevent the original from being caught on the surface of the transparent cover. In addition, even when the transparent cover body has grooves, dust can be prevented from being accumulated in the grooves. Therefore, the image reading process can be appropriately performed. The image reading area is preferably linear, and the transparent cover preferably has an opaque area corresponding to at least the side end portion of the linear image reading area. Β According to the above configuration, it can be used without hindering the normal An opaque area is set on the premise of execution of the original image reading process, so that it is possible to perform an image reading process for the opaque area. In addition, the image signal obtained through the above-mentioned opaque £ image acquisition processing can be used to achieve the output level adjustment of the read image, which is the same as or similar to the above-mentioned "white level adjustment" method. Therefore, "even if the image sensor is used in a palm-type scanner that does not use a sheet press", according to the present invention, the output level of the read image can be adjusted. Therefore, according to the present invention, a read image with excellent image reproducibility and high quality can be obtained.

It is preferable that the opaque region has a white spot formed on one side and a black spot formed on the other side. It is preferable that the opaque region is set by applying a treatment to make a part of the glass member opaque. It is more preferable that the opaque region is provided by partially coating the glass member. The opaque region is preferably completed by adhering an opaque member to a part of the glass member. According to the above-mentioned structures, since the method of providing an opaque area in the transparent cover does not need to prepare a special member which is not integral with the glass member, it is not necessary to assemble the special member in the transparent cover or the like. Therefore, the disadvantages of an increase in the number of parts of the transparent cover and an increase in manufacturing cost can be suppressed. It is preferable that the opaque portion is installed by accommodating an opaque member which is not integrated with the cover body and the glass breaking member in the groove.

Description of the invention (η) The lower part of the light space 50a.裾 Zhao uses plural light sources 52, for example, ΕΕ). On the substrate 51, the host ρ contains a and the door is scanned side by side. ^ This space 50a has a light beam that can be emitted from the plural ^ ▼ source of the plural source 52. The transparent cover k is illuminated from the rear side of the transparent cover by the light path soldier. As described above, since the outer box 50 is a white synthetic tree-deer maker, the wall surface of the light guide space 50a becomes a white light reflection surface with high light reflectance. The light-guiding space 50a has a cross-sectional shape capable of directing the light emitted from the plurality of light sources 52 to the entire glass breaking rod 20 of the transparent cover 1. A lens ㈣54 is used to focus the light from the original document ' to image the i-line component image in the main scanning direction of the original document D onto the multiple light receiving element 53. The lens array 54 is, for example, a plurality of autofocus lenses euf_fQeussing which can form a portrait image of an original document in an upright position and arranged side by side in a row ', and these are held by a resin fixture. Instead of the autofocus lens, a convex lens array or other types of optical lenses may be used today. The lens array 54 is embedded in the groove 50 (1 of the outer box 50), and is assembled in the outer box 50 in a posture extending in the main scanning direction. In addition, the lens array 54 is connected with the transparent cover 1 The glass strips 20 are opposite to each other, and are disposed on the back side of the transparent cover τ. A plurality of light receiving elements 5 3 ′ mounted on the surface of the substrate 51 in the direction of the main drawing are arranged side by side in a line to the self lens The array 54 is spaced at a predetermined interval so that its light receiving surface can be arranged opposite to the lens array 54. Each light receiving element 53 has a photoelectric conversion function, and one receives the light focused by the lens array 54 'That is, the output corresponds to the amount of light received.

Description of Invention (I3) Out-of-standard portrait signal. The weekly garden of each light receiving element 53 It is surrounded by the color support member 55. This structure prevents the light passing through the lens array 54 from being scattered by the white wall surface around each light receiving element 53 due to the white resin of the outer box 50, so that it is incident on each light receiving element 53, so that The phenomenon that affects the read image occurs. Since the plurality of light receiving elements 53 ′ are arranged in the main scanning direction in a state facing the lens array 54, they can read the linear regions extending in the main scanning direction of the original D. This image corresponds to an example of the so-called image reading area S of the present invention. The image reading area S extends in the optical axis direction of the lens array 54 (the line direction indicated by the symbol c in FIG. 7). Therefore, 'not only the surface of the transparent cover 1 but also an area deviating from the surface in the thickness direction of the transparent cover 1 is included in the range of the image reading area S. However,' in the image sensor A of this embodiment The focal position of the lens array 54 is on the surface 20a of the glass strip 20. The transparent cover 1 is such that the center of the width direction of the groove 11 and the glass strip 20 can be aligned with the image reading area S- As shown in FIG. 8, the transparent cover 1 has an opaque area 3 at one end portion of the image reading area S extending in the main scanning direction. The transparent cover 1 is included in one end portion of the lens array 54 and corresponds to this portion. The range [a of the plurality of light-receiving elements 53 (hereinafter referred to as "adjustment light-receiving element") is opposite to the opaque region 3. Therefore, the image reading of the opaque region 3 is performed by the light-receiving elements 53 for adjustment.

Description of the invention (14). First, in FIG. 7, in order to read the image of the original D, light emitted from the plurality of light sources 52 is irradiated on the original D located on the surface u of the transparent cover i. Among the rays of light irradiating the original D, the light reflected by the line-shaped image reading area S on the original d passes through the glass strip 20 of the transparent cover and enters the inside of the image sensor A, and advances toward the lens array. Then, the light is focused and received by the lens array 54 on the light-receiving surface of the plurality of light-receiving elements 53. Because of the high hardness of the surface of the glass strip 20, damage caused by contact with the tabletting roller 6 or other events is unlikely to occur. On the other hand, although the surface 10a of the cover body 10 made of synthetic resin may be easily injured, this part is not within the range of the image reading area s. Therefore, the flaw does not affect the reading process of the original image. "Very large adverse effects" Therefore, the original image 0 reading distortion caused by surface scratches caused by the surface of the transparent cover can be prevented as much as possible. In addition, when the glass strip 20 is embedded in the groove u of the cover body 10, these surfaces are set to have a flat shape with no step difference. Therefore, the original D is stuck on the surface of the transparent cover and becomes the original. Reading the cause of the processing obstacle can also prevent it. In addition, the 'transparent cover 1' is a cover body 10 made of synthetic resin, which occupies most of its area. Therefore, it has the characteristics of light weight and impact resistance, and at the same time, the glass strip 20 having poor impact resistance is provided in a small size. Therefore, it can promote the weight reduction of the product. Furthermore, since the glass strip 20 is embedded in the groove n, it can be protected by the cover body 10. Therefore, the transparent cover 1 is not only susceptible to the cover body but also the entire glass strip 20 and the like, and is not prone to problems such as cracking. In addition, the cover body 10 is made of synthetic resin. Therefore, by using the resin of a steel mold, the paper size is applicable to the Chinese national standard (CNS> A4 specification (210x 297 mm)) 311146 --------! | 1 'Install --- ^ ------ Order ------- Pain (please read the note on the back?

Description of the invention (u) The forming process can be easily performed by "providing, for example, the protrusions 12a to 12b for joining" on the cover body 10, and it is also possible to form it into an appropriate shape when it is assembled in the outer box 50. The present invention Before performing the above-mentioned original reading process, the image sensor A can adjust the output level of the read image without using the platen roller 6. That is, to perform the output level adjustment of the read image, first In a state where the original D is not supplied on the transparent cover 1, the image source is read for the white point 30 and the black point 31 of the opaque area 3 shown in FIG. 8 when the plurality of light sources 52 are turned on in advance. Because the position of the opaque area 3 'is not on the surface 2 0a of the glass strip 20 A little lower, so 'when imaging the portrait of the opaque area 3; there is not much chance of focus deviation. When performing the image reading process of the opaque area 3', a high output bit about the white point 30 can be obtained The standard image signal and the image signal about the low-round output level of the black dot 31. Therefore, referring to the output levels of these two types of image signals, change the voltage value applied to the multiple light source 52, for example, so as to obtain a signal corresponding to the The image signal of the output level of the image density or color tone of the original D can be realized. Figs. 9 and 10 are cross-sectional views each showing another example of the image sensor. In the drawings, the same parts as those in the previous embodiment are given the same reference numerals, and descriptions thereof are omitted. The image sensor Aa shown in FIGS. 9 and 10 is the same as the image sensor in the previous embodiment. The differences between A and their structures are as follows: The position of the original set to align the focal point of the image of the original using the transparent array 54 is not set on the surface 20a of the glass strip 20, but on the paper. Standards are applicable to China National Standard (CNS) A4 specifications (210 X 297 mm) 311146 — — — — — — — — --------------------------- line ( Please read the precautions on the back before filling in this page) 465220 Α7 Β7 V. Description of the invention (16) Those who are only a small distance h from the surface 20a. As for the structure of the other parts, it is the same as the previous implementation. The same image sensor A is the same. In the configuration shown in FIG. 9, the image sensor Aa is used as a constituent member of a palm-type scanner device. The palm-type scanner device is in its outer box 50 Or a casing (not shown) for supporting the outer box 50 is provided with a roller (not shown) so as to separate the surface 1 a of the transparent cover 1 from the original D ′. A certain distance h faces each other. The focus position of the lens array 54 of the image sensor Aa appears at a position different from that of the image sensor A in the front, and this is why. When the image sensor Aa is used as a component of a palm-type scanner device, since the transparent cover 1 of the image sensor Aa is exposed to the outside, it is prone to be impacted by collision with various objects. Phenomenon. However, as mentioned earlier, the transparent cover 1 has excellent impact resistance. In addition, since the opaque area can be used (although it is not disclosed in Figure 9 but it is the same as the previous implementation), the image sensor Aa can independently adjust the output level of the read image. Printed by an employee consumer cooperative is therefore 'especially advantageous for palm-type scanner units that cannot adjust output levels with a platen. The structure shown in FIG. 10 is a paper-feed scanner device similar to the day image sensor A disclosed in FIG. 7 by using the image sensor Aa. However, a transparent glass plate 7 having a thickness η is interposed between the platen roller 6A and the transparent cover 1. In the embodiment of FIG. 10, the design of the day image sensor Aa of FIG. 9 is not changed, and the design is directly used. Therefore, the refractive index of the transparent glass plate 7 is η and the thickness is H. From the original paper size in Figure 9, the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applied. 16 (Please read the note on the back first (Fill in this page again) 311146 A7
