Description

Technical Field

[0001] This invention relates to the field of photocopying technology, and more specifically to a direct-print photocopying device. Background Technology

[0002] Photocopiers are commonly used copying devices in work and life. Traditional photocopiers are expensive and generally only used in large commercial settings. They are also bulky and cannot be carried around, so they can only be placed in a fixed location. In the face of today's rapidly developing economy, they can no longer meet the needs of various new usage scenarios such as business trips, working from home, home learning, online classes, and offline review, and cannot be popularized for individuals and families.

[0003] Therefore, some portable small copiers have emerged, which have solved the problem of large printing equipment being inconvenient to carry to some extent. However, these small copiers are extremely sensitive to light conditions. When the light is too strong, the copies will be overexposed, while when the light is too dim, the copies cannot clearly reproduce the original document content. As a result, these small copiers are greatly affected by ambient light and cannot meet users' printing needs, causing inconvenience to users. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a direct-dip copying device that solves the technical problem that copying equipment in the prior art is greatly affected by ambient light.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] Please see Figures 1 to 3 The direct-projection copying device provided by the present invention is used to copy the content to be copied. While reducing the size and making it easy to carry, it can also adjust the copying light according to the ambient light, thereby adapting to the ambient light and reducing the impact of the ambient light on the copying quality.

[0027] In one embodiment, the direct-projection copying device includes a device body 100, a first PCB board 200, a supplementary light module 300, an imaging module 400, and a copying module 500. The device body 100 has a copying area. The first PCB board 200 is mounted on the device body 100. The supplementary light module 300 is electrically connected to the first PCB board 200. The supplementary light module 300 is used to project supplementary light into the copying area, and the supplementary light module 300 has an adjustment component 310 for adjusting the size of the coverage area of ​​the supplementary light. The imaging module 400 is mounted on the device body 100 and is used to capture an image of the content to be copied placed in the copying area. The copying module 500 is electrically connected to the imaging module 400 and is used to copy the content to be copied based on the image.

[0028] In this embodiment, the device body 100 serves as the main structure of the entire direct-to-display photocopying device. It has the advantages of small size and portability. The device body 100 has a copying area; when copying is required, the content to be copied is placed within the copying area. It should be noted that this embodiment of the invention does not limit the specific structure of the device body; any structural form that satisfies the functions of small size and portability can be used in the technical solution of this invention.

[0029] The first PCB board 200 is mounted on the device body 100 and is used to drive the supplementary light module 300 so as to provide supplementary light according to the ambient light. The first PCB board 200 has a driving circuit printed on it. The driving circuit can drive the supplementary light module 300 to work. In this embodiment, the specific form of the driving circuit is not limited. For example, it can be a conventional LED lamp driving circuit or a switching circuit, etc. The present invention does not limit this.

[0030] The supplementary lighting module 300 is used to project supplementary lighting light into the copying area to achieve supplementary lighting function. It can adjust the light required for the copying area according to the ambient light, so that the copying quality of the copying device is not affected by the ambient light. Moreover, the supplementary lighting module 300 has an adjustment component 310 that can adjust the size of the coverage area of ​​the supplementary lighting light, so that the coverage area of ​​the supplementary lighting light can be adjusted according to the intensity of the ambient light and the position of the content to be copied, ensuring copying quality and making it convenient for users to use.

[0031] The imaging module 400 is used to capture an image of the content to be copied within the copying area, so that the copying module can copy the content based on the image, thus meeting the user's copying needs.

[0032] This invention, through the configuration of a first PCB board 200 and a supplementary lighting module 300, controls the supplementary lighting module 300 to provide supplementary lighting. This allows the lighting in the copying area to be adjusted according to ambient light, ensuring copy quality is unaffected by ambient light. Furthermore, the supplementary lighting module 300 includes an adjustment component 310 to adjust the coverage area of ​​the supplementary lighting, allowing for adjustments as needed, further facilitating user operation and ensuring copy quality. In addition, the direct-projection copying device provided by this invention is small in size and portable, making it suitable for various application scenarios. Moreover, this invention can also acquire images of different positions of the content to be copied within the copying area by adjusting the position of the imaging module 400, enabling one-click cropping and copying of the desired area, further providing convenience to the user.

[0033] Furthermore, since the present invention can adjust the coverage area of ​​the supplementary light after setting the adjustment component 310, it can be applied to copying various fixed-size contents to be copied, wherein the contents to be copied include but are not limited to A1, A2, A3, A4, A5, A6, A7, B1, B2, B3, B4, B5, B6, B7 and C-type and K-type paper sizes.

[0034] In one embodiment, the device body 100 includes a support arm 110 and a shooting arm 120. The copying area is located below the shooting arm 120. The shooting arm 120 is rotatably connected to the support arm 110. The supplementary lighting module 300 is mounted on the shooting arm 120 and can project supplementary lighting light downwards from the shooting arm 120.

[0035] In this embodiment, during copying, the support arm 110 and the imaging arm 120 are perpendicular, forming a 90° angle. When not copying, the imaging arm 120 can be retracted by rotating it 90° to overlap with the support arm 110, facilitating storage and portability for the user, reducing size and providing convenience. Furthermore, the support arm 110 provides a fixed and suitable height for the entire copying device, thus facilitating the acquisition of higher quality original copies.

[0036] When performing a copying operation, the area below the imaging arm 120 is the copying area. The user only needs to place the content to be copied below the imaging arm 120. The supplementary light module 300 on the imaging arm 120 can provide supplementary light to the copying area, and the imaging module 400 on the imaging arm 120 can take pictures of the content to be copied in the copying area, thereby achieving direct projection copying and increasing the copying quality.

[0037] In one embodiment, the supplementary lighting module 300 further includes an LED lamp 320 and a lens group 330. The LED lamp 320 is electrically connected to the first PCB board 200, and the lens group 330 is installed below the LED lamp 320. The LED lamp 320 projects supplementary light through the lens group 330. The adjustment component 310 is installed inside the lens group 330 and can adjust the size of the coverage area of ​​the supplementary light from the LED lamp 320 passing through the lens group 330.

[0038] In this embodiment, the LED lamp 320 is used to project supplementary light through the lens group 330, and the first PCB board 200 is used to control the switching of the LED lamp 320 to control the working state of the supplementary light module 300. For example, when the first PCB board 200 sends a high level to the LED lamp 320, the LED lamp is turned on, and when the first PCB board 200 sends a low level to the LED lamp 320, the LED lamp is turned off.

[0039] Because the light emitted by the LED lamp 320 is not concentrated and covers a small area, this embodiment of the invention also includes a lens group 330. The lens group 330 can increase the coverage area of ​​the supplementary light, thereby allowing the light emitted by the LED lamp 320 to cover the copying area and meet the user's printing needs. Furthermore, the adjustment component 310 installed in the lens group 330 can adjust the coverage area of ​​the light from the LED lamp 320 passing through the lens group 330 to meet the copying needs of different paper sizes. Figure 1 As shown, when the LED lamp 320 emits light, it generates light path S1. After passing through the lens group 330, light path S1 forms light path S2. By adjusting the position of the adjustment component 310, the coverage area of ​​light path S2 can be adjusted.

[0040] In one embodiment, please refer to... Figure 1 and Figure 2 The lens group 320 includes four lens groups arranged from top to bottom. Figure 1 The adjustment component 310 is located between the two uppermost lens groups (lens groups G1, G2, G3, and G4).

[0041] In this embodiment, since the light path between the two uppermost lens groups is closest to a parallel light path, the adjustment component 310 is located between the lens group G1 and the lens group G2. When the light path S1 generated by the LED lamp 310 passes through the lens group G1, part of the light path S1 is blocked by the adjustment component 310, and the other part passes through the adjustment component 310, lens group G2, lens group G3 and lens group G4 in sequence to form the light path S2. By adjusting the size of the light coverage through the adjustment component 310, the coverage area of ​​the light path S2 can be adjusted, thereby meeting the different copying needs of users.

[0042] In one embodiment, please refer to... Figure 1 and Figure 2 The adjustment assembly 310 includes an adjustment handle 311 and a film 312. The film 312 has a fixed light-transmitting area and a light-blocking area. The film 312 is located between any two adjacent lens groups. The adjustment handle 311 is connected to the film 312 and is used to adjust the size of the area of ​​the film 312 to adjust the relative position of the light-transmitting area of ​​the film 312 in the lens group 330.

[0043] In this embodiment, since the film 312 has fixed light-transmitting and opaque areas, when the light generated by the LED lamp 320 shines on the film, the light shining on the opaque area of ​​the film 312 is blocked and cannot continue to pass down. The light shining on the light-transmitting area of ​​the film 312 can pass through the film 312 and then sequentially through lens group G2, lens group G3, and lens group G4 to form the light path S2. When the user needs to change the size of the supplementary lighting area, the position of the film 312 can be adjusted by adjusting the handle 311, changing the position of the opaque area of ​​the film 312. This allows adjustment of the illumination angle of the light passing through the light-transmitting area 312, thereby adjusting the coverage area of ​​the light path S2.

[0044] In one embodiment, see Figure 1 and Figure 2 The shooting module 400 includes an image sensor 410 and a lens 420. The image sensor 410 is electrically connected to the copying module 500 and is mounted on the shooting arm 120. The image sensor 410 and the lens 420 are arranged vertically at intervals. The lens 420 is used to image on the image sensor 410, and the image sensor 410 is used to send the image to the copying module 500.

[0045] In this embodiment, the coverage area S3 of the lens 420 is larger than the copying area, thereby ensuring that the image sensor 410 can acquire an image of the content to be copied within the copying area through the lens 420. After acquiring the image, the image sensor 410 sends the image to the copying module 500, which performs the copying to obtain a photocopy. The image sensor 410, in conjunction with the focal length of the lens 420, can produce higher quality photocopies.

[0046] Preferably, the lens 420 is an adjustable lens, meaning its viewing angle is adjustable. Therefore, it can capture images from specific angles. Thus, when the content to be copied is placed within the copying area, adjusting the viewing angle of the lens 420 allows for one-click cropping and copying of the desired area, further enhancing user convenience. Of course, in some embodiments, the lens 420 can also be a fixed lens. By manually adjusting the position of the content to be copied within the copying area, the lens 420 can capture images of different positions of the content, thereby enabling the copying of the desired content.

[0047] In one embodiment, please refer to... Figure 1 The copying module 500 includes a second PCB board 510 and a print head 520. The second PCB board 510 is electrically connected to the image sensor 410 and the print head 520. The print head 520 is disposed inside the support arm 110. The second PCB board 510 is used to receive the image sent by the image sensor 410 and drive the print head 520 to print according to the image.

[0048] In this embodiment, after acquiring the image, the second PCB board 510 can drive the print head 520 to print, thereby printing the acquired image to obtain the desired copy. The print head 520 is preferably a thermal print head, and its printing specifications can be set according to the printing area.

[0049] In one embodiment, see Figure 1 The direct-projection copying device also includes a lithium battery 600, which is electrically connected to the first PCB board 200 and the supplementary lighting module 300.

[0050] In this embodiment, the lithium battery 600 provides power to the direct-to-display photocopying device. The lithium battery 600 is electrically connected to the first PCB board 200, the LED light 320, the second PCB board 510, and the print head 520 to ensure the normal operation of each component.

[0051] In one embodiment, see Figure 1In order to increase the battery life of the direct-to-display copier, the device body 100 is also provided with a charging port 100a, through which the user can power the lithium battery 600, thereby avoiding frequent battery replacements and ensuring normal use by the user.

[0052] In one embodiment, see Figure 1 The device body 100 is also equipped with capacitive buttons for printing control. Figure 1 The device includes buttons K1 and K2. The capacitive buttons can prevent camera shake. When the camera is clicked to take a picture, the camera shake can be minimized, thereby obtaining a higher quality original image.

[0053] In one embodiment, the direct-to-display photocopying device further includes a storage chip C1, which is electrically connected to the second PCB board 510 and can store images captured by the imaging module 400 for easy reprinting.

[0054] In one embodiment, to meet the needs of mobile office and mobile learning, the direct-to-distribution photocopying device further includes a communication chip C2 (e.g., a WIFI chip). The communication chip C2 is electrically connected to the second PCB board 510, which allows users to connect to the network and upload and store data to a cloud server for convenient mobile office and learning as well as remote task push.

[0055] In summary, the direct-projection copying device provided by this invention, by setting up a first PCB board and a supplementary light module, controls the supplementary light module to provide supplementary light through the first PCB board. This allows the light in the copying area to be adjusted according to ambient light, ensuring that the copying quality is unaffected by ambient light. Furthermore, the supplementary light module also has an adjustment component that can adjust the coverage area of ​​the supplementary light, allowing for adjustments to the supplementary light as needed, further facilitating user operation and ensuring copying quality. In addition, the direct-projection copying device provided by this invention also has the advantages of small size and portability, making it suitable for various application scenarios.
