Fig. 2 shows a schematic diagram of a partial structure of the image reading apparatus 100 according to the present invention. Specifically, the image reading apparatus 100 includes a document table 10 on which a document is placed, a reading section 20 positioned above the document table 10, and a conveying section 30 provided with a reading guide section 21. The reading position is formed between the reading section 20 and the document table 10. The conveying unit 30 includes a conveying roller 31 and a conveying guide portion 32, the conveying roller 31 is located on the upstream side of the reading position and conveys the original to the reading position, the conveying guide portion 32 is located on the downstream side of the conveying roller 31 and includes an upper guide portion 321 and a lower guide portion 322, and the upper guide portion 321 and the lower guide portion 322 are curved and extended from the conveying roller 31 toward the downstream side in the original conveying direction and guide the original from the conveying roller 31 to the reading position. In the embodiment according to the present invention, the conveyance guide 32 may be in the form of a guide rail, and the upper guide 321 and the lower guide 322 are an upper guide rail and a lower guide rail, respectively. A plurality of pairs of the conveying rollers 31 are provided along the width direction of the lower guide portion 322, that is, a direction parallel to the rotation axis of the conveying roller 31 (a direction perpendicular to the paper surface in fig. 2). Further, a downstream conveying section 90 including a downstream conveying roller 91 and a downstream guide section 92 for conveying the read document is provided on the downstream side of the reading position.
As shown in fig. 3, the solid line portion indicates an ideal position of the lower guide portion 322, and the dotted line portion indicates a position of the lower guide portion 322 after being deformed due to warpage or the influence of component accuracy. After the conveyance guide section 32 is fixed, the lower guide section 322 itself is deformed downward due to the influence of the accuracy of the parts and the warp, and at this time, a gap is generated between the original and the lower guide section 322, and when the gap is relatively large, the original is decelerated relatively largely due to resistance received by the leading end when the original protrudes into the downstream side guide section 92. In practical use, both ends of the lower guide portion 322 in the width direction thereof are fixed, so that the downward deformation occurs mainly in the middle portion of the lower guide portion 322 in the width direction thereof.

According to the image reading apparatus of the embodiment of the invention, the position of the lower guide part is adjusted to a proper position by the adjusting mechanism, and the deformation of the lower guide part caused by the influence of the component precision is corrected; the document conveying device avoids tip deceleration during the conveying process of the document, particularly when the document protrudes into a downstream side guide part, ensures the stability of the document during the conveying process, and avoids image problems caused by speed variation.
Fig. 4 shows a schematic configuration diagram of a first embodiment of an adjustment mechanism of an image reading apparatus according to the present invention. In this embodiment, the adjustment mechanism 40 includes a base 41 and an adjustment portion 42. The base 41 may be mounted on a structural frame of the image reading apparatus, and the lower end of the adjusting portion 42 is adjustably mounted on the base 41 and the upper end supports the lower guide portion 322. The position of the adjusting part 42 relative to the base 41 is adjustable, for example, the adjusting part 42 is a threaded rod having threads, the base 41 is provided with threaded holes matched with the threaded rod, and the adjusting part 42 is rotated to move the adjusting part 42 upward relative to the base 41, thereby raising the height of the lower guide part 322.
In practical applications, a displacement sensor may be provided to detect the displacement of the lower guide portion 322 moving downward, and a driving device such as a motor may be provided to drive the adjusting portion 42 to move upward, or the user may manually adjust the adjusting portion 42 until the lower guide portion 322 reaches or approaches the ideal position shown by the solid line in fig. 3. Thus, the adjusting mechanism 40 adjusts the relative positions of the lower guide portion 322 and the document table 10 so that the end of the lower guide portion 322 adjacent to the reading position is kept horizontal, thereby ensuring that the document contacts the lower guide portion 322 during conveyance.
In the preferred embodiment shown in fig. 4, the lower side of the lower guide portion 322 is provided with a support portion 3221 for supporting the lower guide portion 322, and the lower end of the support portion 3221 has a flat surface. The upper end of the adjusting part 42 also has a flat surface so that the adjusting part 42 moves upward to be in planar contact with the lower end of the supporting part 3221 of the lower guide part 322, and then the adjusting part 42 continues to move upward, thereby elevating the height of the lower guide part 322. In this embodiment, the adjusting portion 42 and the supporting portion 3221 have a flat surface contact therebetween, which facilitates adjustment and support of the lower guide portion 322. Alternatively, in other embodiments, the supporting portion 3221 may be formed at the upper end of the adjusting portion 42 of the adjusting mechanism 40, and the upper end of the supporting portion 3221 has a curved surface cooperating with the lower guide portion 322 for contacting and supporting the lower guide portion 322.
The embodiment uses the lower guide part position adjusting mechanism, and the height of the lower guide part is better controlled, so that the relative position of the original and the lower guide part is ensured, the occurrence of gaps is avoided, the speed of the original can be kept stable in the conveying process, and the image quality is ensured.
Fig. 5 to 6 are schematic structural views showing a second embodiment of an adjusting mechanism of an image reading apparatus according to the present invention. In this embodiment, the adjustment mechanism 50 adjusts the relative positions of the lower guide portion 322 and the document table 10 by a link mechanism. Specifically, the adjustment mechanism 50 includes a base 51, a T-shaped link 52, a spring 53, and a screw 54. The base 51 may be fixed to a structural frame of the image reading apparatus, and the T-shaped link 52 includes a first link 521 and a second link 522 vertically extending from a middle portion of the first link 521, the second link 522 for supporting the lower guide 322. As shown in the drawing, the second link 522 is in plane contact with the lower guide 322. The T-shaped link 52 is mounted to the base 51 through a rotating shaft 523 installed in a middle portion of the first link 521 such that the T-shaped link 52 can rotate about the rotating shaft 523. The spring 53 has one end connected to the base 51 and the other end connected to a first end of the first link 521, for example, an upper end of the first link 521 shown in fig. 5. The screw 54 passes through a threaded hole on the base 51, and one end of the screw 54 abuts against a second end of the first link 521, i.e., the end opposite to the connecting spring 53.
When the T-shaped link 52 is arranged as shown in fig. 5 to 6, in the initial state, the first link 521 is in the vertical direction, the second link 522 is in the horizontal direction, the spring 53 is in a certain compressed state, the spring 53 exerts a force on the T-shaped link 52, the T-shaped link 52 is maintained in a certain stressed state, the position of the T-shaped link 52 is adjusted by tightening or loosening the screw 54, and the position of the lower guide portion 322 is adjusted. When the screw 54 is tightened to the right, the screw 54 moves to the right and pushes the T-shaped link 52 to rotate counterclockwise, so that the lower end of the first link 521 rotates to the right, and thus the second link 522 pushes the lower guide 322 to move upward, and the upper end of the first link 521 rotates to the left, thereby compressing the spring 53; conversely, loosening the screw 54 to the left moves the screw 54 to the left, and the entire T-shaped link 52 rotates clockwise by the spring 53, so that the second link 522 and the lower guide 322 move downward. In this embodiment, the height adjustment mechanism 50 can adjust the height in 2 vertical directions according to the actual tolerance of the component and the actual warping direction, and can adjust the lower guide portion 322 down or up. The spring 53 is not limited to a compression spring, and may be a torsion spring or an extension spring.
Fig. 7 shows a schematic configuration diagram of a third embodiment of an adjustment mechanism of an image reading apparatus according to the present invention. The reading section 20 is movable relative to the document table 10 to close or open the reading section 20, and when the reading section moves relative to the document table 10 to close the reading section 20, the adjusting mechanism 60 is in contact with the document table, and the position of the lower guide section is adjusted by pushing the adjusting mechanism upward via the document table. More specifically, the adjustment mechanism 60 includes an adjustment portion 61 and a contact portion 62 located below the adjustment portion 61, the adjustment portion 61 being mounted on the lower guide portion 322 at a fulcrum 63, the contact portion 62 being a protrusion extending downward from the adjustment portion 61. In one embodiment, the adjusting portion 61 and the contact portion 62 are integrally formed, for example, made of an elastic material having a certain elasticity, and may be a polyurethane resin or other materials. When the reading section 20 moves relative to the document table 10 to close the reading section 20, the contact portion 62 of the adjustment mechanism 60 contacts the document table 10, and the contact portion 62 of the adjustment mechanism 60 is pushed up by the document table 10 to adjust the relative position of the lower guide portion 322 and the document table 10. Alternatively, the adjustment mechanism 60 and the lower guide portion 322 are integrally formed to obtain a simple structure and reduce production costs.
In other embodiments, the adjusting portion 61 and the contact portion 62 of the adjusting mechanism 60 are separate two members, the adjusting portion 61 forms a part of the lower guide portion 322, and the contact portion 62 is fixed to the adjusting portion 61 such that the contact portion 62 of the adjusting mechanism 60 is in planar contact with the lower guide portion 322.
Fig. 8 is a schematic configuration diagram showing a fourth embodiment of the adjusting mechanism of the image reading apparatus according to the present invention, and the adjusting mechanism 70 is an adjusting portion extending from the tip of the lower guide portion 322. Specifically, the adjustment mechanism 70 includes a fulcrum 71 and a document table contact portion 72, and the document table contact portion 72 of the adjustment mechanism 70 is connected to the lower guide portion 322 through the fulcrum 71, for example, a rotating shaft. When the reading portion 20 moves relative to the document table 10 to close the reading portion 20, the document table contact portion 72 contacts the document table 10 and then rotates upward around the fulcrum 71 by the document table 10, thereby ensuring that a certain distance is maintained between the lower guide portion 322 and the document table 10 without being deformed downward too much. In this embodiment, the adjustment mechanism 70 contacts the document table 10 by the document table contact portion 72 having an inclined surface, instead of contacting the document table 10 by a projection.
In this embodiment, the adjusting structure 70 uses the fulcrum rotating mechanism to adjust the position of the lower guide portion, so that the correction of the lower guide portion can be realized without the limitation of space, and the force point can be selected at any position according to the size of the space, and the adjusting mechanism is relatively simple to realize.
Fig. 9 is a schematic configuration diagram showing a fifth embodiment of the adjusting mechanism of the image reading apparatus according to the present invention, and the adjusting mechanism 80 is an adjusting portion extending from the tip of the lower guide portion 322. In this embodiment, the adjustment mechanism 80 is integrally formed with the lower guide portion 322, one end of which is in contact with the document table 10 and the other end of which has a thin-walled portion 81, for example, the thin-walled portion 81 is formed by providing a groove on the lower side of the lower guide portion 322. The thin-walled portion 81 may be deformed by a force. In this embodiment, the lower guide portion 322 is thinner than other portions at a position immediately downstream of the conveying roller 31, and since the lower guide portion is made of resin, the thin-walled portion 81 can twist as a fulcrum. The end of the adjusting mechanism 80 has a contact surface that contacts the document table 10. When the lower guide rail portion 322 or the adjustment mechanism 80 contacts the document table 10, the contact force between the lower guide portion 322 and the document table 10 deforms the lower guide portion 322, thereby correcting the deformation of the lower guide portion 322 due to the warpage. The image reading apparatus according to the embodiment has a simple structure, a reduced number of parts, convenience in implementation, and a low cost.
Fig. 10 shows a schematic configuration diagram of a sixth embodiment of an adjustment mechanism of an image reading apparatus according to the present invention. The figure shows an adjustment mechanism 40 according to a first embodiment of the invention, although adjustment mechanisms according to other embodiments of the invention may alternatively be used. In the case where only one adjustment mechanism is provided, the adjustment mechanism 40 is located below the middle portion of the lower guide portion 322 in the width direction thereof. In the case where two adjustment mechanisms 40 are provided, the two adjustment mechanisms 40 are symmetrically installed below both sides of the lower guide portion 322 in the width direction thereof. In the case where a plurality of adjustment mechanisms 40 are provided, the plurality of adjustment mechanisms 40 are symmetrically installed below both sides of the lower guide portion 322 in the width direction thereof. The width direction of the lower guide portion 322 is the left-right direction shown in fig. 10, that is, a direction parallel to the rotation axis of the conveying roller 31. By adjusting these adjustment mechanisms, the position of the lower guide portion 322 is corrected, and the lower guide portion 322 is prevented from being deformed downward. The arrangement of the plurality of adjusting mechanisms in the symmetrical distribution can well ensure that the same conveying speed can be realized at the front and the back of the whole original, and the phenomenon of speed reduction at a single place is avoided.
The number and position of the adjustment mechanisms can be adjusted by one skilled in the art according to specific application, and the present invention is not limited thereto. The symmetrical distribution of the adjusting mechanisms ensures the uniform conveying speed of the front side and the back side of the original manuscript, thereby ensuring the image quality.
While the technical content and the technical features of the invention have been disclosed, it is understood that various changes and modifications of the disclosed concept can be made by those skilled in the art within the spirit of the invention, and the invention is not limited thereto. The above description of embodiments is intended to be illustrative, and not restrictive, and the scope of the invention is defined by the appended claims.
