Description

Technical Field

[0001] The utility model relates to a scanning device and image forming equipment. Background Art

[0002] Image forming devices such as multi-function printers have a scanning function. Users can manually place documents on the platen glass for scanning. When using a flatbed scanner, users are required to place the material to be scanned in the correct position according to the size of the material to be scanned to ensure the scanning quality. If the placement is incorrect, the scan is prone to skew or even partial image loss.

[0003] Usually, there are labels corresponding to standard paper types (such as A4, A5) next to the draft glass of the scanning device, so that users can accurately identify the placement of standard paper types. However, when users need to scan documents, especially when they need to scan the front and back sides, since the cross-sectional area of ​​the document is small, and the area of ​​the draft glass of the scanning device is large relative to the cross-sectional area of ​​the document, users often do not know how to place the document, and then need to try repeatedly to obtain the desired scanned image, which seriously affects the user experience.

[0004] In order to solve the above problems, the prior art has the following two methods. One solution is to affix guidance information on how to place the document to complete the front and back scanning of the document on the upper cover of the ADF in a scanning device with an automatic document feeder (ADF). However, since the user needs to flip the ADF upwards when using a flatbed scanner, the information affixed to the upper cover of the ADF cannot be seen at this time. If the user wants to view the guidance information, the ADF needs to be flipped over continuously, which affects the user experience. Another solution is to set the guidance information on the plastic shell next to the manuscript glass. However, since the size of the plastic shell is very small, only very small guidance information can be set, and the amount of information is very limited. It is usually difficult for users to correctly understand, which also affects the user experience. Utility Model Content

[0005] According to one aspect of the utility model, a scanning device is provided, comprising:

[0006] An upper cover and a lower cover, wherein the lower cover is located below the upper cover;

[0007] A platen glass and a top cover, wherein the platen glass is mounted on the upper cover and has a scanning area for placing materials, the lower cover is provided with a material mark corresponding to the scanning area, and when viewed from a vertical direction, the material mark overlaps the scanning area, and the top cover is used to cover the upper cover to press the material onto the platen glass;

[0008] The image reading module disposed between the upper cover and the lower cover can be moved to read the image of the material on the platen glass.

[0009] The scanning device of the utility model is provided with a material mark corresponding to the scanning area of ​​the platen glass on the lower cover. When the user uses the flatbed scanning, the material mark on the lower cover can be viewed through the platen glass. The user only needs to place the material in the scanning area corresponding to the platen glass and the material mark on the lower cover to ensure that the material placement position can meet the scanning operation of the scanning device. The image reading module can move to read the image of the material to be scanned on the scanning area to complete the scanning operation. Therefore, the scanning device of the utility model can avoid the situation where the user's material scanning is skewed or even the image is missing due to the inaccurate material placement position, and the material mark on the lower cover is convenient for the user to identify, thereby improving the user experience.

[0010] In some embodiments, the material identification is an identification of the front and back sides of the material placed in the scanning area.

[0011] In some embodiments, the scanning area includes a first scanning area and a second scanning area that are offset in position, and when viewed from a vertical direction, the material mark overlaps on the first scanning area and / or the second scanning area.

[0012] In some embodiments, one of the first scanning area and the second scanning area is a front scanning area, and the other is a back scanning area, the material mark includes a front mark and a back mark, the front mark overlaps on the front scanning area, and the back mark overlaps on the back scanning area.

[0013] In some implementations, the material identification is used to demonstrate the process of material scanning.

[0014] In some embodiments, the material identification is a label sticker, an engraved layer, a silk-screen layer, a laser engraved layer, or a spray-painted layer covering the lower cover.

[0015] In some embodiments, standard size marks are provided on two adjacent side edges of the upper cover, and when viewed from a vertical direction, the scanning area is located in an area close to the two side edges having the standard size marks.

[0017] In some embodiments, a background plate for adhering to the material is installed on the inner side of the top cover.

[0018] According to another aspect of the utility model, an image forming device is provided, comprising an image forming device body and the scanning device, wherein the scanning device is electrically connected to the image forming device body.

[0019] The image forming device of the utility model is provided with a scanning device on the upper part of the image forming device body, and the lower cover of the scanning device is provided with a material mark corresponding to the scanning area of ​​the platen glass. When the user uses the flatbed scanning, the material mark on the lower cover can be viewed through the platen glass, and the user only needs to place the material in the scanning area corresponding to the platen glass and the material mark on the lower cover to ensure that the position of the material placement can meet the scanning operation of the scanning device, and the image reading module can move to read the image of the material to be scanned on the scanning area to complete the scanning operation. Therefore, the scanning device of the utility model can avoid the situation where the user's material scanning is skewed or even the image is missing due to the inaccurate material placement position, and the material mark on the lower cover is convenient for the user to identify, thereby improving the user experience.

[0032] In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0033] Please refer to Figure 7The utility model provides an image forming device, comprising an image forming device body 17 and a scanning device, wherein the scanning device is arranged on the upper part of the image forming device and is electrically connected to the image forming device body 17.

[0034] Please refer to Figure 1 , 7 The scanning device includes an upper cover 10, a lower cover 11, a platen glass 12, a top cover 13, an image reading module 15 and an ADF. The upper cover 10 and the lower cover 11 are arranged on the upper part of the image forming device body 17 from top to bottom; the platen glass 12 is installed on the upper cover 10, and the platen glass 12 is used to place the material to be scanned; the top cover 13 is rotatably installed on the upper cover 10 so as to cover or open the upper cover 10, the background plate 16 is installed on the inner side of the top cover 13, and the ADF is arranged on the top cover 13; the image reading module 15 is arranged between the upper cover 10 and the lower cover 11 and is electrically connected to the image forming device body 17, the image reading module 15 includes an image reading device, a track, and a driving device (such as a motor), and the image reading device can be a contact image sensor (Contact Image Sensor, CI S).

[0035] When performing a scan job (copying includes scanning), please refer to Figure 1 , 7 , the user places the material to be scanned (such as paper, certificate) on the platen glass 12 and closes the top cover 13. At this time, the background plate 16 will provide pressure on the paper to ensure that the paper is flat on the platen glass 12. When the user starts scanning, the image reading device will move along the track to read the image. Specifically, the image reading device emits light to the area on the upper surface of the platen glass 12 where the paper is pressed by the background plate 16 (i.e. upward). The light can pass through the transparent platen glass 12 and reach the paper (passing through the paper) and the background plate 16 (the background part is opaque). Then the light is reflected (downward) and received by the light receiving part of the image reading device. Since the light reflected by different parts of the paper (blank / colored) is different, the light signal received by the light receiving part of the image reading device is also different. Then, after photoelectric conversion and calculation, the image data on the paper is finally obtained to achieve scanning.

[0036] Please refer to Figure 1When scanning, the user can independently set the output size of the scanned image / the paper size of the copy (for example, the user can place A4-sized paper on the platen glass 12 and choose to scan to A4 size or copy A4 size). At this time, the user needs to place the paper to be scanned at the specified position of the platen glass 12 to ensure that the scanned image of the specified size can be output. Usually, there will be a mark corresponding to the standard paper type (such as A4, A5) next to the platen glass 12 of the scanning device, that is, the standard size mark, and the user can accurately identify the placement of the standard paper type. However, when the user needs to scan the certificate, especially when scanning the front and back sides, due to the small cross-sectional area of ​​the certificate, and relative to the cross-sectional area of ​​the certificate, the area of ​​the scanning device's platen glass 12 is large, the user is often unclear about how to place the certificate, and then needs to make repeated attempts to obtain the desired scanned image, which seriously affects the user experience.

[0037] To solve the above problems, the scanning device provided by the present invention is as follows Figure 2-6 The scanning device has a scanning area for placing materials on the draft glass 12, and a material mark 14 corresponding to the scanning area (document placement area) is set on the lower cover 11 of the scanning device. When viewed from the vertical direction, the material mark 14 overlaps with the scanning area. The overlap here includes two implementation methods: complete overlap and partial overlap. The above-mentioned material mark 14 can be a sticker or an engraving set on the lower cover 11. When the user scans the document, please refer to Figure 2-3 , the user can see the material mark 14 set on the lower cover 11 through the manuscript glass 12. The user only needs to refer to the material mark 14 and place the document in the scanning area corresponding to the manuscript glass 12 to ensure that it has been placed in the correct scanning position. Therefore, the scanning device of the utility model can avoid the situation where the user's material scanning is skewed or even the image is missing due to the inaccurate placement of the material, and the material mark 14 on the lower cover 11 is convenient for the user to identify, thereby improving the user experience.

[0038] For specific implementation, please refer to Figure 2-6 The material identification 14 is an identification placed on the front and back of the material in the scanning area. The material identification 14 is a label sticker or an engraved layer or a silk-screen layer or a laser engraved layer or a spray-painted layer covering the lower cover 11. It can be displayed in the form of a label sticker, engraving on a part, silk-screen printing, laser engraving, or spray-painting. The setting of the material identification 14 includes at least the following three implementation methods:

[0039] The first implementation method: please refer to Figure 4 , the scanning area is a document placement area, the front and back sides of the document are placed in the same area, the algorithm is used to arrange the front and back images, and then the scanned image / copy is output, preferably in the form of mold engraving;

[0040] The second implementation method: please refer to Figure 5 , the scanning area includes a first scanning area and a second scanning area that are staggered in position. When observed from a vertical direction, the material identification 14 overlaps the first scanning area and / or the second scanning area. Due to the arrangement of the CIS rail, the first scanning area and the second scanning area are divided on both sides of the CIS rail. Specifically, the first scanning area is located on the upper side of the CIS rail and is set as the front scanning area, and the second scanning area is located on the lower side of the CIS rail and is set as the back scanning area. The material identification 14 includes a front identification and a back identification. When observed from a vertical direction, the front identification overlaps the front scanning area, and the back identification overlaps the back scanning area, that is, the front and back sides of the document have different placement positions. The user places the front and back sides in sequence with reference to the positions of the front identification and the back identification. Due to the staggered positions themselves, the requirements for the image processing algorithm are reduced, and it is preferably displayed in the form of mold engraving. Of course, the front scanning area can also be located on the lower side of the CIS rail and the back scanning area can be located on the upper side of the CIS rail;

[0041] The third implementation method: please refer to Figure 6 The material identification 14 is used to display the process of material scanning (document scanning), preferably in the form of a label sticker.

[0042] Please refer to Figure 1-6 By setting the material mark 14 on the lower cover 11, the user can view the material mark 14 through the platen glass 12 as long as the user uses the flatbed scanning, and the guidance for the user is more intuitive and clear. The setting of the material mark 14 also satisfies: the image reading module 15 can move from one side of the scanning area to the other side to read the image of the material to be scanned. The upper cover 10 is provided with standard size marks at two adjacent sides. Since the starting position of the CIS is on the left, preferably, the two sides of the upper left corner of the upper cover 10 are provided with standard size marks. When observed from the vertical direction, the scanning area is in the area close to the two sides with standard size marks, that is, the scanning area is set in the area close to the upper left of the platen glass 12. Of course, the above-mentioned two standard size marks can also be arranged corresponding to the two sides of the lower left corner of the upper cover 10, so that the scanning area is set in the area close to the lower left of the platen glass 12. When scanning a document, the image reading device only needs to move from the leftmost end of the scanning area to the rightmost end of the scanning area and then return, without moving the entire stroke, thereby shortening the scanning time.

[0043] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
