Description

Paper delivery mechanism and scanning device

Technical Field

The present disclosure relates to paper delivery technologies, and particularly to a paper delivery mechanism and a scanning device.

Background

The scanning device can meet the requirement of fast scanning of a large number of files, and scanning equipment such as a multifunctional office machine carrying an Automatic Document Feeder (ADF) gradually becomes one of necessary tools for working occasions. Generally, in order to improve the smoothness of paper output after scanning, most of the current mainstream machines employ a paper output structure disposed between two glass plates separated from each other, and the portion of the guiding surface of the paper output structure adjacent to the glass plate is lower than the surface of the glass plate for receiving the document; or a transparent polyester film (Mylar film) is covered at the communication part of the paper conveying channel and the glass plate.

However, in the scanning apparatus using two glass plates, the static electricity accumulated during scanning affects the electrical property of the image sensor located under the glass plates through the gap between the two glass plates, thereby reducing the quality of the scanned image, and the cost and the assembly difficulty are high. On the other hand, because the polyester film is arranged between the glass plate and the document, the definition of image scanning is easily influenced by the configuration condition of the film, and the surface of the polyester film is easily scratched by a document under long-time use, so that the scanning quality of the image is reduced.

Detailed Description

Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Fig. 1 is a sectional side view of a scanning device according to a first embodiment of the invention. Fig. 2 is a schematic view of the scanning apparatus of fig. 1. Fig. 3 and 4 are enlarged schematic views of portions of the scanner of fig. 2 at two different viewing angles. Fig. 5A is a schematic view of the guide of fig. 3. It should be noted that, for the sake of clarity, fig. 2 omits the illustration of the main body 110, the image sensor 120 and the automatic document feeder 200 of fig. 1.

Referring to fig. 1, a scanning device 10 includes a scanner 100 and an automatic document feeder 200. In the present embodiment, the scanner 100 is a flatbed scanner (flatbed scanner). That is, the scanning device 10 may be a printer with copy and scan functions, but the invention is not limited thereto. In other embodiments, the scanning device may also be a sheet-fed high-speed scanning device without a manual scanning platform. Further, the scanner 100 includes a body 110, an image sensor 120, and a transparent substrate 130. The transparent substrate 130 is disposed on the body 110 and has a first surface 130a and a second surface 130b opposite to each other. The image sensor 120 is disposed on the second surface 130b of the transparent substrate 130.

For example, the image sensor 120 is movably disposed in the body 110 to provide an image scanning function. In this embodiment, the image sensor 120 may include a light source 121, a lens array 122, and an image sensing device 123. That is, the image sensor 120 is exemplarily illustrated as a Contact Image Sensor (CIS). However, the present invention is not limited thereto, and according to other embodiments, the image sensor may also be a photo reduction (optical reduction) type image sensor including a reflection assembly, a lens assembly, and a Charge Coupled Device (CCD).

On the other hand, the automatic document feeder 200 is configured to convey the document to the scanning region SR of the transparent substrate 130 along the sheet feeding path P for image scanning. In detail, the automatic document feeder 200 has a conveying channel 210 and a cover 220. The cover 220 is disposed on a side of the auto document feeder 200 facing the scanner 100, and has an opening 220a overlapping the scanning region SR. The transmitting channel 210 communicates with a portion of the first surface 130a of the transparent substrate 130 located in the scanning region SR via the opening 220 a. More specifically, the conveying path 210 may include a paper feeding path 211 and a paper discharging path 212, and the paper feeding path 211 and the paper discharging path 212 are respectively connected to two opposite sides of the scanning region SR (or the opening 220a of the cover 220).

For example, the paper feeding channel 211 and the paper discharging channel 212 can respectively communicate with the transparent substrate 130 from the left side and the right side of the scanning region SR in fig. 1. That is, the document to be scanned can reach the side of the cover 220 defining the opening 220a (e.g., the left side of the opening 220a in fig. 1) by being conveyed through the paper feeding path 211. After passing through the scanning region SR and completing the image scanning, the document may enter the paper output channel 212 and be output from the other side (e.g., the right side of the opening 220a in fig. 1) of the opening 220a defined by the cover 220. On the other hand, in order to improve the scanning quality of the image, the automatic document feeder 200 may further include a paper pressing mechanism 230 so that the document delivered to the scanning area SR can be closely attached to the first surface 130a of the transparent substrate 130.

Referring to fig. 1 to 4, the scanning device 10 further includes a paper discharging mechanism 155. The paper output mechanism 155 is disposed in the opening 220a of the cover 220 and overlaps the transparent substrate 130. Further, the paper discharging mechanism 155 includes a guiding member 160 and an elastic member 170 (as shown in fig. 3). The guide 160 is disposed between the automatic document feeder 200 and the first surface 130a of the transparent substrate 130, and has an end 161 facing the scanning region SR. The elastic member 170 is configured to abut the end 161 of the guide 160 against the first surface 130a of the transparent substrate 130. Therefore, the paper discharging smoothness of the scanned manuscript can be effectively improved. For example, the thinnest point (e.g., tip fillet) of the end 161 can be less than or equal to 50 microns thick in a direction perpendicular to the first surface 130 a.

In the present embodiment, the number of the guiding elements 160 and the number of the elastic elements 170 are exemplarily illustrated by five, respectively, which does not mean that the present invention is limited by the disclosure of the drawings. In other embodiments, the number of the guiding elements 160 and the elastic elements 170 can be adjusted according to the actual document size. For example, in order to improve the service life of the paper discharging mechanism, the material of the end 161 of the guide 160 may be metal. However, the present invention is not limited thereto, and according to other embodiments, the material of the end 161 of the guide 160 may also be a plastic material, such as Polycarbonate (PC) or polypropylene (PP), but is not limited thereto.

Specifically, in order to ensure the scanning quality of the document, the sheet discharge mechanism 155 does not overlap the scanning region SR in the normal direction of the transparent substrate 130 (as shown in fig. 2). However, the invention is not limited thereto, and according to other embodiments, the paper discharging mechanism 155 may also partially overlap the scanning region SR of the transparent substrate 130. Further, the scanner 100 further includes a housing 140 disposed on the body 110. The housing 140 partially covers the transparent substrate 130 and exposes the scanning region SR of the transparent substrate 130. In the embodiment, the paper output mechanism 155 is selectively disposed on the housing 140, but the invention is not limited thereto.

In detail, the housing 140 may have a transverse rib 141 overlapping the transparent substrate 130, and a plurality of (e.g., five) guides 160 are disposed on the transverse rib 141 of the housing 140 separately from each other. More specifically, the lateral rib 141 may have a plurality of (e.g., five) slots 141a corresponding to the guides 160, and the slots 141a face the scanning region SR. The guide 160 is disposed in the slot 141a, and the end 161 protrudes from the slot 141 a. Further, the guiding member 160 further has a pivoting portion 162 away from the end 161. The pivoting portion 162 is pivoted to the lateral rib 141 along an axis AX such that the guide 160 can rotate relative to the lateral rib 141 along the axis AX. For example, the guide 160 may be pivotally connected to the transverse rib 141 by a shaft 165. In the embodiment, the end 161 and the pivot portion 162 of the guiding element 160 may be integrally formed, but the invention is not limited thereto. On the other hand, the distribution of the plurality of guides 160 can improve the convenience of maintenance and reduce the maintenance cost, for example: only the damaged guide 160 needs to be replaced.

Referring to fig. 3 to 5A, in the present embodiment, the elastic member 170 is, for example, a torsion spring (torsion spring). That is, the elastic member 170 may have a spring body 171 and a first spring arm 172 and a second spring arm 173 at opposite ends of the spring body 171. For example, the transverse rib 141 and the guide 160 may also have a positioning groove 141b and a positioning notch 160a, respectively. The spring 171 of the elastic member 170 is sleeved on the rotating shaft 165 along the axis AX. The first spring arm 172 and the second spring arm 173 can be respectively fastened to the positioning groove 141b of the transverse rib 141 and the positioning notch 160a of the guiding element 160, so that the elastic element 170 is fixedly disposed between the transverse rib 141 and the guiding element 160.

Referring to fig. 1, it should be noted that when the end 161 of the guiding element 160 abuts against the first surface 130a of the transparent substrate 130, the spring 171 of the elastic element 170 can pivot along the axis AX to accumulate an elastic potential energy. From another perspective, the elastic potential can provide a counter force to the guide 160, such that the end 161 moves toward the transparent substrate 130 to abut against the first surface 130a of the transparent substrate 130. In other words, the disposition of the elastic member 170 can ensure that the end 161 of the guiding member 160 abuts against the transparent substrate 130 of the scanner 100, which is helpful to improve the smoothness of the paper output after the document is scanned.

For example, after the document passes through the scanning region SR, the abutting relationship between the end 161 and the transparent substrate 130 ensures that the document can be sequentially conveyed to the paper output channel 212 along the guide surface 160s of the guide 160 and the guide surface 141s of the transverse rib 141. Specifically, the paper feeding path 211, the portion of the first surface 130a located in the scanning region SR, the guiding surface 160s of the guiding member 160, the guiding surface 141s of the transverse rib 141, and the paper discharging path 212 define a paper feeding path P of the scanning device 10. On the other hand, due to the configuration relationship between the guiding element 160 and the transparent substrate 130, the scanning device 10 can satisfy different scanning requirements by only providing one transparent substrate 130, such as automatic scanning of a large number of documents or manual scanning of a single document, which is helpful to reduce the manufacturing cost and the assembly difficulty.

Fig. 5B-5D are schematic views of guides of other embodiments. Referring to fig. 5B, the main difference between the guide 160A of the present embodiment and the guide 160 of fig. 5A is: the configuration of the guides is different. In this embodiment, the guiding element 160A may be composed of two parts, namely a first part 160A1 and a second part 160A2, wherein the pivoting portion 162 and the end portion 161A are respectively disposed on the first part 160A1 and the second part 160A 2. More specifically, the first member 160A1 has an end 160A1A distal from the pivot 162 (i.e., toward the scanning area), and the end of the second member 160A2 distal from the end 161A is connected to the end 160A1A of the first member 160A 1.

In the embodiment, the connection relationship between the first member 160a1 and the second member 160a2 can be realized by adhesion, but the invention is not limited thereto. In other embodiments, the connection relationship between the two components can be realized by clamping. That is, the second member 160A2 is removably connected to the first member 160A 1. For example, when end 161A is damaged, only the second component needs to be replaced. Therefore, the maintenance convenience of the guide can be increased by the detachable relationship of the two parts. On the other hand, in the present embodiment, the materials of the first and second parts 160A1 and 160A2 of the guide 160A may be selectively different. For example, the materials of the first and second members 160a1 and 160a2 may be plastic and metal materials, respectively. However, the invention is not limited thereto, and according to other embodiments, the materials of the two parts may alternatively be the same.

Referring to fig. 5C, the difference between the guide 160B of the present embodiment and the guide 160A of fig. 5B is: the second component is of a different configuration. Specifically, in the axial direction of the rotating shaft 165, the width of the end 161B of the second part 160B2 of the guide 160B is significantly greater than the width of the first part 160a 1. That is, by increasing the width (or area) of the guide surface 160s, the stability of the document after scanning can be further improved. Referring to fig. 5D, the difference between the guide 160C of the present embodiment and the guide 160A of fig. 5B is: the second member is of a different material. In the present embodiment, the second part 160C2 of the guiding element 160C may be a polyester film (Mylar film) and has flexibility. For example, when the end 161C of the guide 160C abuts against the transparent substrate 130, the second member 160C2 may be bent to extend from the end 160A1a of the first member 160 A1. Specifically, the thickness of the second member 160C2 (or the end 161C) made of mylar can be further reduced, which helps to improve the smoothness of the paper output after the document is scanned.

Fig. 6 is a sectional side view of a scanning device according to a second embodiment of the invention. Referring to fig. 6, the main differences between the scanning device 11 of the present embodiment and the scanning device 10 of fig. 1 are: the paper discharge mechanism is configured in different ways. In the present embodiment, the paper output mechanism 155A can be disposed on the cover 220 of the automatic paper feeder 200. Specifically, the guiding element 160D is pivotally connected to the cover 220 through the rotating shaft 165, and two opposite ends of the elastic element 170A are respectively inserted through the through hole 160b of the guiding element 160D and the through hole 220b of the cover 220. For example, the elastic element 170A is, for example, an extension spring (extension spring), and the through hole 160b and the end 161 of the guiding element 160D are respectively located at two opposite sides of the rotating shaft 165, and the through hole 160b is located between the rotating shaft 165 and the transparent substrate 130.

In response, when the end 161 of the guiding element 160D abuts against the first surface 130A of the transparent substrate 130, the elastic element 170A can be stretched in the connection direction of the two through holes (i.e., the through hole 160b and the through hole 220b) to accumulate an elastic potential energy. From another perspective, the elastic potential can provide a counter force to the guide 160D, so that the end 161 thereof moves toward the transparent substrate 130 to abut against the first surface 130a of the transparent substrate 130. In other words, the disposition of the elastic member 170A can ensure that the end 161 of the guiding member 160D abuts against the transparent substrate 130 of the scanner 100, which is helpful to improve the smoothness of the paper output after the document is scanned.

Fig. 7 is a schematic view of a scanning apparatus according to a third embodiment of the present invention. Specifically, for the sake of clarity, fig. 7 only shows the transparent substrate 130, the housing 140A and the paper discharging mechanism 155B. Referring to fig. 7, the main differences between the scanning device 12 of the present embodiment and the scanning device 10 of fig. 2 are: the arrangement of the guide members. In the present embodiment, the paper discharging mechanism 155B is disposed on the first surface 130A of the transparent substrate 130 of the scanner 100A. In detail, the guiding element 160E may be composed of two parts, namely a first part 160E1 and a second part 160E2, wherein the second part 160E2 has an end 161, and the elastic element 170B is disposed between the first part 160E1 and the transparent substrate 130. For example, the paper discharging mechanism 155B can be fixed on the first surface 130a of the transparent substrate 130 by an adhesive layer (not shown).

It should be noted that the elastic member 170B of the paper discharging mechanism 155B is, for example, an elastic film. When the end 161 of the guide 160E abuts against the first surface 130a of the transparent substrate 130, the elastic element 170B is stretched substantially along the normal direction of the transparent substrate 130 to accumulate an elastic potential energy. From another perspective, the elastic potential can provide a counter force to the guide 160E, so that the end 161 moves toward the transparent substrate 130 to abut against the first surface 130a of the transparent substrate 130. In other words, the disposition of the elastic member 170B can ensure that the end 161 of the guiding member 160E abuts against the transparent substrate 130 of the scanner 100A, which is helpful to improve the smoothness of the paper output after the document is scanned. In this embodiment, the material of the elastic member 170B may include polymer, silicone, rubber, or other suitable elastic material.

Fig. 8 is a schematic view of a scanning apparatus according to a fourth embodiment of the present invention. Fig. 9 is a schematic view of a scanning apparatus according to a fifth embodiment of the present invention. Specifically, for the sake of clarity, fig. 8 only shows the transparent substrate 130, the housing 140B and the paper discharging mechanism 155C. Referring to fig. 8, the main differences between the scanning device 13 of the present embodiment and the scanning device 10 of fig. 2 are: the paper discharging mechanism has different configurations. In the present embodiment, the guiding member 160F of the paper discharging mechanism 155C further has an adhering portion 163, wherein the guiding member 160F is adhered to the transverse rib 141A of the casing 140B through the adhering portion 163. However, the invention is not limited thereto, and according to other embodiments, the guide 160F of the paper output mechanism 155C can be adhered to the cover 220 of the automatic paper feeder 200A (as shown in the scanning device 14 of fig. 9).

On the other hand, the elastic member 170C is, for example, an elastic film, and is connected between the adhesion portion 163 of the guide member 160F and the transverse rib 141A. In other words, by the configuration of the elastic member 170C, the guide 160F can be positioned on the transverse rib 141A of the housing 140B, and the end 161 of the guide 160F abuts against the first surface 130a of the transparent substrate 130. At this time, the elastic element 170C is stretched substantially along the normal direction of the transparent substrate 130 to accumulate an elastic potential energy. From another perspective, the elastic potential energy accumulated by the elastic adhesive film can provide a reverse force to the guide 160F, so that the end 161 thereof moves toward the transparent substrate 130 to abut against the first surface 130a of the transparent substrate 130. In other words, the disposition of the elastic member 170C can ensure that the end 161 of the guide 160F abuts against the transparent substrate 130 of the scanner 100B, which is helpful to improve the smoothness of the paper output after the document is scanned.

Particularly, in the present embodiment, the material of the adhesion portion 163 and the end portion 161 of the guide 160F may be selectively the same. For example, the guiding member 160F may be an integrally formed stainless steel sheet, but the invention is not limited thereto.

Fig. 10 is a schematic view of a scanning apparatus according to a sixth embodiment of the present invention. Specifically, for the sake of clarity, fig. 10 only shows the transparent substrate 130, the housing 140B and the paper discharging mechanism 155D. Referring to fig. 10, the main differences between the scanning device 15 of the present embodiment and the scanning device 13 of fig. 8 are: the paper discharging mechanism has different configurations. In the present embodiment, the plurality of guides 160G may be connected to each other. More specifically, the guides 160G may further optionally include a connection portion 164, and the guides 160G are connected to each other by the connection portion 164. Particularly, the positioning relationship between the plurality of guides 160G can be ensured by the arrangement of the connecting portions 164. On the other hand, the connecting portion 164 and the adhesion portion 163A of the guide 160G can be used to adhere the guide 160G to the transverse rib 141A of the housing 140B. For example, the guiding member 160G can be adhered to the transverse rib 141A of the housing 140B by an adhesive layer (not shown) overlapping the adhesive portion 163A and the connecting portion 164.

In the embodiment, the plurality of guides 160G connected to each other may be an integrally formed Mylar film (Mylar film), but the invention is not limited thereto. In general, the polyester film itself may have elasticity. Therefore, the paper discharging mechanism 155D may not have an elastic member, but the invention is not limited thereto. In other embodiments, not shown, the guiding member 160G can be adhered to the transverse rib 141A of the housing 140B by an elastic member, such as an elastic film.

In summary, in the paper discharging mechanism and the scanning device according to an embodiment of the invention, the plurality of guiding members are suitable to be disposed between the scanner and the automatic paper feeder, and the end portions of the guiding members are abutted against the transparent substrate of the scanner through the disposition relationship of the elastic members. Therefore, the paper discharging smoothness after the file scanning can be ensured, and the service life of the paper discharging mechanism is effectively prolonged. In addition, the guide piece is not overlapped with the scanning area, and the scanning quality of the file can be effectively improved. On the other hand, the scanning device can meet different scanning requirements (such as automatic scanning of a large number of documents or manual scanning of a single document) by only configuring one transparent substrate, which is beneficial to reducing the manufacturing cost and the assembly difficulty of the scanning device.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
