In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

Fig. 1 is a cross-sectional side view of a scanning device according to a first embodiment of the present invention. Fig. 2 is a schematic diagram of the scanning device of Fig. 1. 3 and 4 are enlarged schematic diagrams of a part of the scanner of FIG. 2 at two different viewing angles. Fig. 5A is a schematic diagram 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 in FIG. 1.

Please refer to FIG. 1, the scanning device 10 includes a scanner 100 and an automatic document feeder 200. In this embodiment, the scanner 100 is a flatbed scanner. That is, the scanning device 10 may be a business machine with photocopying and scanning functions, but the invention is not limited to this. In other embodiments, the scanning device may also be a paper-fed high-speed scanning device without a manual scanning platform. Furthermore, 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 130 b 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 sensor 123. That is to say, the image sensor 120 is exemplified by taking a contact image sensor (CIS) as an example. However, the present invention is not limited to this. According to other embodiments, the image sensor may also be an optical reduction (optical reduction) image sensor including a reflective element, a lens element, and a charge coupled device (CCD).

On the other hand, the automatic document feeder 200 is configured to convey the document along the paper feeding path P to the scanning area SR of the transparent substrate 130 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 the side of the automatic document feeder 200 facing the scanner 100, and has an opening 220a overlapping the scanning area SR. The conveying channel 210 communicates with the portion of the first surface 130a of the transparent substrate 130 located in the scanning area SR through the opening 220a. More specifically, the conveying channel 210 may include a paper feeding channel 211 and a paper output channel 212, and the paper feeding channel 211 and the paper output channel 212 are respectively connected to opposite sides of the scanning area SR (or the opening 220a of the cover 220). .

For example, the paper feeding channel 211 and the paper output channel 212 may be respectively connected to the transparent substrate 130 from the left side and the right side of the scanning area SR in FIG. 1. In other words, the document to be scanned can be conveyed through the paper feed channel 211 to the side where the cover 220 defines the opening 220a (for example, the left side of the opening 220a in FIG. 1). After passing through the scanning area SR and completing the image scanning, the document may enter the paper output channel 212 from the other side of the opening 220 a defined by the cover 220 (for example, the right side of the opening 220 a in FIG. 1) and be conveyed out. 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 transferred to the scanning area SR can be closely attached to the first surface 130a of the transparent substrate 130.

Please refer to FIGS. 1 to 4, the scanning device 10 further includes a paper ejection mechanism 155. The paper ejection mechanism 155 is disposed in the opening 220 a of the cover 220 and overlaps the transparent substrate 130. Furthermore, the paper ejection mechanism 155 includes a guide 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 area SR. The elastic member 170 is configured to abut the end 161 of the guide member 160 against the first surface 130 a of the transparent substrate 130. Accordingly, it can effectively improve the smoothness of the document output after scanning. For example, in the direction perpendicular to the first surface 130a, the thickness of the thinnest part (for example, the tip rounded corner) of the end portion 161 may be less than or equal to 50 microns.

In this embodiment, the number of the guide member 160 and the number of the elastic member 170 is illustrated by taking five respectively as an example, which does not mean that the present invention is limited by the content of the drawings. In other embodiments, the configuration number of the guide member 160 and the elastic member 170 can also be adjusted according to the actual file size. For example, in order to increase the service life of the paper ejection mechanism, the material of the end 161 of the guide 160 may be metal. However, the present invention is not limited to this. 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 not This is limited.

In particular, in order to ensure the scanning quality of the document, the paper ejection mechanism 155 does not overlap the scanning area SR in the normal direction of the transparent substrate 130 (as shown in FIG. 2 ). However, the present invention is not limited to this. According to other embodiments, the paper ejection mechanism 155 may also partially overlap the scanning area SR of the transparent substrate 130. Furthermore, 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 area SR of the transparent substrate 130.

In detail, the housing 140 may have lateral ribs 141 overlapping the transparent substrate 130, and a plurality of (for example, five) guide members 160 are separately provided on the lateral ribs 141 of the housing 140. More specifically, the lateral rib 141 may have a plurality of (for example, five) grooves 141 a corresponding to the guide members 160, and the grooves 141 a face the scanning area SR. The guiding member 160 is disposed in the slot 141a, and the end 161 extends from the slot 141a. Furthermore, the guiding member 160 also has a pivoting portion 162 away from the end portion 161. The pivotal portion 162 is pivotally connected to the transverse rib 141 along an axis AX, so that the guide member 160 can rotate relative to the transverse rib 141 along the axis AX. For example, the guiding member 160 may be pivotally connected to the transverse rib 141 through the rotating shaft 165. In this embodiment, the end 161 of the guiding member 160 and the pivoting portion 162 may be integrally formed, but the present invention is not limited to this. On the other hand, through the dispersed arrangement relationship of the plurality of guides 160, the convenience during maintenance can be improved and the maintenance cost can be reduced. For example, only the damaged guides 160 need to be replaced.

Please refer to FIGS. 3 to 5A. In this embodiment, the elastic member 170 is, for example, a 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 located at opposite ends of the spring body 171. For example, the lateral rib 141 and the guide 160 may also have a positioning groove 141b and a positioning recess 160a, respectively. The spring body 171 of the elastic member 170 can be sleeved on the rotating shaft 165 according to the axis AX. The first spring arm 172 and the second spring arm 173 can be respectively buckled in the positioning groove 141b of the transverse rib 141 and the positioning recess 160a of the guide member 160, so that the elastic member 170 is fixed on the transverse rib 141 and the guide member 160 between.

1 at the same time, it is worth mentioning that when the end 161 of the guide member 160 abuts the first surface 130a of the transparent substrate 130, the spring body 171 of the elastic member 170 can pivot along the axis AX to accumulate a Elastic potential. From another point of view, the elastic potential can provide a reverse force on the guide 160, so that its end 161 moves in a direction approaching the transparent substrate 130 and abuts on the first surface 130a of the transparent substrate 130 . In other words, the arrangement relationship of the elastic member 170 can ensure that the end 161 of the guide member 160 abuts against the transparent substrate 130 of the scanner 100, which helps to improve the smoothness of the document ejection after scanning.

For example, after the document passes through the scanning area SR, the abutment relationship between the end 161 and the transparent substrate 130 can be used to ensure that the document can be guided along the guide surface 160s of the guide 160 and the lateral ribs 141 in sequence. The surface 141s is conveyed to the paper discharge channel 212. In particular, the paper feeding channel 211, the part of the first surface 130a located in the scanning area SR, the guiding surface 160s of the guiding member 160, the guiding surface 141s of the transverse rib 141, and the paper output channel 212 can define the scanning device 10 The paper feed path P. On the other hand, due to the configuration relationship between the guide 160 and the transparent substrate 130, the scanning device 10 only needs to provide a transparent substrate 130 to meet different scanning requirements, such as automatic scanning of a large number of documents or manual scanning of a single document, which is helpful To reduce its manufacturing cost and assembly difficulty.

5B to 5D are schematic diagrams of guide members of other embodiments. Please refer to FIG. 5B. The main difference between the guide member 160A of this embodiment and the guide member 160 of FIG. 5A is that the configuration of the guide member is different. In this embodiment, the guide 160A may be composed of two parts, namely the first part 160A1 and the second part 160A2, wherein the pivot part 162 and the end part 161A are respectively provided on the first part 160A1 and the second part 160A2 . More specifically, the first member 160A1 has an end 160A1a away from the pivoting portion 162 (that is, toward the scanning area), and the end of the second member 160A2 away from the end 161A is connected to the end 160A1a of the first member 160A1.

In this embodiment, the connection relationship between the first component 160A1 and the second component 160A2 can be achieved through adhesion, but the present invention is not limited to this. In other embodiments, the connection relationship between the two components can also be realized through a snap connection. That is, the second part 160A2 is detachably connected to the first part 160A1. For example, when the end 161A is damaged, only the second part needs to be replaced. Therefore, the maintenance convenience of the guide can be increased through the detachable relationship of the two parts. On the other hand, in this embodiment, the materials of the first part 160A1 and the second part 160A2 of the guide 160A may be selectively different. For example, the materials of the first component 160A1 and the second component 160A2 may be plastic materials and metal materials, respectively. However, the present invention is not limited to this, and according to other embodiments, the materials of the two components may also be selectively the same.

Please refer to FIG. 5C. The difference between the guide 160B of this embodiment and the guide 160A of FIG. 5B is that the configuration of the second component is different. 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 larger than the width of the first part 160A1. In other words, by increasing the width (or area) of the banner 160s of the guide surface, the stability of the document transmission after scanning can be further improved. Referring to FIG. 5D, the difference between the guide 160C of this embodiment and the guide 160A of FIG. 5B is that the material of the second component is different. In this embodiment, the second component 160C2 of the guide 160C may be a Mylar film and has flexibility. For example, when the end 161C of the guide 160C abuts on the transparent substrate 130, the second part 160C2 can be bent and extends from the end 160A1a of the first part 160A1. In particular, the thickness of the second part 160C2 (or the end 161C) of the polyester film can be further reduced, which helps to improve the smoothness of the paper output after the document is scanned.

Fig. 6 is a cross-sectional side view of a scanning device according to a second embodiment of the present invention. Please refer to FIG. 6, the main difference between the scanning device 11 of this embodiment and the scanning device 10 of FIG. 1 is that the configuration of the paper ejection mechanism is different. In this embodiment, the paper ejection mechanism 155A may be provided on the cover 220 of the automatic paper feeder 200. Specifically, the guide member 160D can be pivotally connected to the cover 220 through the rotating shaft 165, and the opposite ends of the elastic member 170A are respectively penetrated through the through hole 160b of the guide member 160D and the through hole 220b of the cover 220. For example, the elastic member 170A is, for example, an extension spring, and the through hole 160b and the end portion 161 of the guide member 160D are respectively located on opposite sides of the rotating shaft 165, and the through hole 160b is located between the rotating shaft 165 and the transparent substrate 130 .

Continuing the above, when the end 161 of the guide member 160D abuts the first surface 130a of the transparent substrate 130, the elastic member 170A can be stretched in the connecting direction of the two perforations (ie, perforation 160b and perforation 220b) to accumulate An elastic potential. From another point of view, this elastic potential can provide a reverse force on the guide 160D, so that its end 161 moves in a direction approaching the transparent substrate 130 and abuts on the first surface 130a of the transparent substrate 130 . In other words, the arrangement relationship of the elastic member 170A can ensure that the end 161 of the guide member 160D abuts against the transparent substrate 130 of the scanner 100, which helps to improve the smoothness of the output of the document after scanning.

Fig. 7 is a schematic diagram of a scanning device according to a third embodiment of the present invention. In particular, for the sake of clarity, FIG. 7 only illustrates the transparent substrate 130, the housing 140A, and the paper ejection mechanism 155B. Please refer to FIG. 7, the main difference between the scanning device 12 of this embodiment and the scanning device 10 of FIG. 2 lies in the configuration of the guide. In this embodiment, the paper ejection mechanism 155B is disposed on the first surface 130a of the transparent substrate 130 of the scanner 100A. In detail, the guiding member 160E can be composed of two parts, namely a first part 160E1 and a second part 160E2. The second part 160E2 is provided with an end 161, and the elastic part 170B is disposed on the first part 160E1 and the transparent substrate. Between 130. For example, the paper ejection mechanism 155B can be fixed on the first surface 130a of the transparent substrate 130 through an adhesive layer (not shown).

It is worth mentioning that the elastic member 170B of the paper output mechanism 155B is, for example, an elastic film layer. When the end 161 of the guiding member 160E abuts against the first surface 130a of the transparent substrate 130, the elastic member 170B is stretched substantially along the normal direction of the transparent substrate 130 to accumulate an elastic potential energy. From another point of view, the elastic potential can provide a reverse force on the guide 160E, so that its end 161 moves in a direction approaching the transparent substrate 130 and abuts on the first surface 130a of the transparent substrate 130 . In other words, the arrangement relationship of the elastic member 170B can ensure that the end 161 of the guide member 160E abuts against the transparent substrate 130 of the scanner 100A, which helps to improve the smoothness of the document output after scanning. In this embodiment, the material of the elastic member 170B may include polymer, silicone, rubber, or other suitable elastic materials.

Fig. 8 is a schematic diagram of a scanning device according to a fourth embodiment of the present invention. Fig. 9 is a schematic diagram of a scanning device according to a fifth embodiment of the present invention. In particular, for the sake of clarity, FIG. 8 only shows the transparent substrate 130, the housing 140B, and the paper ejection mechanism 155C. Please refer to FIG. 8, the main difference between the scanning device 13 of this embodiment and the scanning device 10 of FIG. 2 is that the configuration of the paper ejection mechanism is different. In this embodiment, the guiding member 160F of the paper ejection mechanism 155C further has an adhesive portion 163, wherein the guiding member 160F is adhered to the lateral rib 141A of the housing 140B through the adhesive portion 163. However, the present invention is not limited to this. According to other embodiments, the guide 160F of the paper ejection mechanism 155C can also be pasted on 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 adhesive portion 163 of the guide member 160F and the lateral rib 141A. In other words, through the configuration of the elastic member 170C, the guide member 160F can be positioned on the lateral rib 141A of the housing 140B, and the end 161 of the guide member 160F can abut the first surface 130a of the transparent substrate 130. At this time, the elastic member 170C is stretched substantially along the normal direction of the transparent substrate 130 to accumulate an elastic potential energy. From another point of view, the elastic potential energy accumulated by the elastic film can provide a reverse force on the guide 160F, so that its end 161 moves in the direction approaching the transparent substrate 130 and abuts against the transparent substrate 130. The first surface 130a of the substrate 130. In other words, the arrangement relationship of the elastic member 170C can ensure that the end 161 of the guide member 160F abuts against the transparent substrate 130 of the scanner 100B, which helps to improve the smoothness of the document ejection after scanning.

In particular, in this embodiment, the materials of the adhesive portion 163 and the end portion 161 of the guide member 160F can be selectively the same. For example, the guiding member 160F may be an integrally formed stainless steel sheet, but the present invention is not limited to this.

Fig. 10 is a schematic diagram of a scanning device according to a sixth embodiment of the present invention. In particular, for the sake of clarity, FIG. 10 only shows the transparent substrate 130, the housing 140B, and the paper ejection mechanism 155D. Please refer to FIG. 10, the main difference between the scanning device 15 of this embodiment and the scanning device 13 of FIG. 8 is that the configuration of the paper ejection mechanism is different. In this embodiment, a plurality of guide members 160G may be connected to each other. More specifically, the guiding member 160G may optionally include a connecting portion 164, and the guiding members 160G are connected to each other through the connecting portion 164. In particular, through the configuration of the connecting portions 164, the alignment relationship between the plurality of guide members 160G can be ensured. On the other hand, both the connecting portion 164 and the adhesive portion 163A of the guide 160G can be used to adhere the guide 160G to the lateral rib 141A of the housing 140B. For example, the guide 160G can be adhered to the lateral rib 141A of the housing 140B by overlapping the adhesive layer (not shown) disposed on the adhesive portion 163A and the connecting portion 164.

In this embodiment, the plurality of guide members 160G connected to each other may be an integrally formed Mylar film, but the present invention is not limited to this. Generally speaking, the polyester film itself can have elasticity. Therefore, the paper ejection mechanism 155D may not have an elastic member, but the present invention is not limited to this. In other non-illustrated embodiments, the guiding member 160G can also be adhered to the lateral rib 141A of the housing 140B through an elastic member, and the elastic member is, for example, an elastic film.

In summary, in the paper ejection mechanism and scanning device of an embodiment of the present invention, a plurality of guides are suitable for being arranged between the scanner and the automatic paper feeder, and the ends of the guides are passed through the elastic member. The arrangement is close to the transparent substrate of the scanner. According to this, it can ensure the smoothness of the paper output after scanning the document, and effectively increase the service life of the paper output mechanism. In addition, the guide does not overlap the scanning area, which can effectively improve the scanning quality of the document. On the other hand, the scanning device only needs to be equipped with a transparent substrate to meet different scanning requirements (such as automatic scanning of a large number of documents or manual scanning of a single document), which helps to reduce its manufacturing cost and assembly difficulty.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention.
