Description

Technical Field

[0001] The present invention belongs to the technical field of printers, and particularly relates to a printer for taking pictures and framing scenes. Background Art

[0002] A wrong-question printer is a tool or device, usually used in the learning or teaching process to help students record and review their wrong questions. Such a device can print out the questions that students have answered incorrectly for them to view, analyze, and correct repeatedly, so as to deepen their memory and improve their problem-solving ability. Such a "wrong-question printer" is usually used in combination with some intelligent learning software or systems. After a student answers a question incorrectly, the system will automatically record the wrong question and generate a wrong-question book, which is printed into a paper version for the student to view in subsequent learning.

[0003] Currently, the wrong-question printers on the market either print the entire test paper for students to redo, or print based on the method of scanning and extracting characters; the disadvantages of this are as follows:

[0004] 1. The printer that prints the entire test paper not only has a large size and is not easy to carry, but also has a lot of consumption of consumables.

[0005] 2. For the printer that scans and extracts characters, when students scan the text of the test paper, there are problems such as skipping characters, skipping questions, and repeated scanning, resulting in missing characters or duplicate questions in the printing.

[0006] 3. When the content on a relatively distant or other-angle plane cannot be scanned in place, the printer needs to be moved as a whole to achieve it, and when moving, the scanning reference position will change, which is not only inconvenient to use but also leads to proportional changes caused by different references.

[0007] 4. In addition, traditional printers of this type can only scan the content on the horizontal plane, and cannot take pictures and recognize the content on, for example, a non-horizontal arc surface or a vertical surface.

[0008] In view of this, we propose a printer for taking pictures and framing scenes. Summary of the Invention

[0009] The purpose of the present invention is to provide a printer for taking pictures and framing scenes to solve the problems raised in the above background art.

[0010] In view of this, the present invention provides a printer for taking pictures and framing scenes, including a printer base, and further including:

[0011] A storage slot, in which a protective shell and a movable shell are provided, and the protective shell is located on top of the movable shell;

[0012] A paper switching button, which is fixedly installed on the printer base;

[0013] Connecting block, the connecting block is movably installed in the movable housing, and a main swing arm is provided on one side of the connecting block. The main swing arm further includes:

[0014] A telescopic component, the telescopic component includes arm one and arm two. Arm one is fixedly installed on one side of the connecting block. A chute is opened in arm one. A sliding plate fixed to arm two is slidably installed in the chute. Limiting grooves are opened on both sides of the chute. Limiting blocks fixed to the sliding plate are slidably installed in the limiting grooves;

[0015] A groove is opened at the bottom of the main swing arm. A card housing is provided in the groove. A light projection component and a camera are provided in the card housing;

[0016] A universal adjustment component is arranged in the main swing arm, so that the light projection component and the camera can be rotationally adjusted. The universal adjustment component includes a universal head. One end of the universal head is rotatably arranged in the first part of the main swing arm, and the other end is rotatably arranged in the second part.

[0017] In this technical solution, through the provided connecting block, students can pull one end of the main swing arm to rotate in the movable housing with the connecting block as the axis, so that the card housing is moved out of the protective housing until the main swing arm is perpendicular to the movable housing. Subsequently, move the main swing arm up and down, so that the main swing arm drives the connecting block to move up and down in the movable housing, so as to solve the problem that the light projection component and the camera can be far away from the printing. The main swing arm can slide up and down, which is convenient for adjusting the size of the light area and convenient for reading various questions of different sizes and lengths on the test paper. Using the principle that the light can be adjusted in size from near to far optically, the edge line of the light area is used to take questions and print. When the light is projected onto the test paper, the film can be visually judged the width of the paper to be printed, so that students can clearly switch between two-inch and three-inch consumables when using the consumables;

[0018] For the convenience of carrying, the viewfinder head of the wrong-question printer in the prior art is made into a foldable camera. When students do not use it, the camera and the light projection component on the whole device can enter the protective housing, and the folded whole device is convenient to put into the schoolbag.

[0019] When the light illuminating convex lens one passes through the film, and then passes through convex lens two, convex lens three and convex lens four and is projected onto the test paper, a complete rectangular area is formed. The area within the boundary box of the bright edge is the content that students need to frame, as Figure 5 shown. The camera can capture the text content within the box for shooting, and then carry out the printing work. The main swing arm can be adjusted up and down to make the rectangular light area larger or smaller, and different-width questions can be recognized.

[0020] In the above technical solution, further, the light projection component includes:

[0021] The protective case is arranged inside the cartridge case. Inside the protective case, there are lamp beads and an inner case. Inside the inner case, there are a first convex lens, a film, a second convex lens, a third convex lens, and a fourth convex lens arranged in sequence from top to bottom.

[0022] In this technical solution, when the light emitted by the lamp beads illuminates the first convex lens, passes through the film, and then passes through the second convex lens, the third convex lens, and the fourth convex lens and is projected onto the test paper, a complete rectangular area is formed.

[0023] In the above technical solution, further, a transparent and smooth glass is provided at the bottom of the cartridge case and below the fourth convex lens and the camera.

[0024] In this technical solution, it is ensured that the transparent and smooth glass can play a protective role for the fourth convex lens and the camera, preventing stains or water from contaminating the fourth convex lens and the camera and causing occlusion, which affects the use of the overall device.

[0025] In the above technical solution, further, one end of the main swing arm penetrates through the connecting block and extends into the printer base. Inside the printer base and below the connecting block, a fixed column is fixedly installed. A tension spring is sleeved on the fixed column, and one end of the tension spring is sleeved on one end of the main swing arm.

[0026] In this technical solution, when the main swing arm is perpendicular to the printer base, the tension spring will tightly pull one end of the main swing arm to prevent the other end of the main swing arm from moving downward.

[0027] In the above technical solution, further, both the protective case and the movable case are fixed to the inner wall of the storage groove by a plurality of screws, and the cartridge case is fixed to the inner wall of the groove by a plurality of bolts.

[0028] In this technical solution, it is ensured that the structures of the protective case and the movable case in the storage groove are stable, and the structure of the cartridge case in the groove is stable.

[0029] In the above technical solution, further, the protective case is in snap-fit with the cartridge case. The inner case is fixed to the inner wall of the protective case by a plurality of screws, and the camera is fixed to the cartridge case by a plurality of screws.

[0030] In this technical solution, it is ensured that the protective case can be snapped into the cartridge case, facilitating the disassembly and installation of the protective case and the cartridge case, and ensuring the structural stability of the inner case and the protective case, as well as the structural stability of the camera and the cartridge case.

[0031] In the above technical solution, further, the first convex lens is in snap-fit with the inner case, and the top of the first convex lens has a planar structure, while the bottom of the first convex lens has an arc-shaped structure.

[0032] In this technical solution, it is ensured that the light emitted by the lamp beads can penetrate the first convex lens to form refraction, ensuring the structural stability of the first convex lens and also facilitating the disassembly and installation of the first convex lens.

[0033] In the above technical solution, further, the cross-section of the film is in a circular structure, and the middle of the film is in a rectangular structure.

[0034] In this technical solution, when the film is precisely cut and segmented, the width of the paper to be printed can be visually judged when the light is projected onto the test paper, enabling students to accurately switch between two-inch and three-inch consumables when using the consumables.

[0035] In the above technical solution, further, the upper and lower sides of the second convex lens and the third convex lens are both in an arc shape, the top of the fourth convex lens is in an arc shape, and the bottom of the fourth convex lens is in a flat structure.

[0036] In this technical solution, it is ensured that the light emitted by the lamp beads can pass through the second convex lens, the third convex lens, and the fourth convex lens to form effective refraction.

[0037] In the above technical solution, further, the film, the second convex lens, the third convex lens, and the fourth convex lens are all snap-fitted with the inner shell.

[0038] In this technical solution, it is convenient to disassemble and install the film, the second convex lens, the third convex lens, the fourth convex lens, and the inner shell.

[0039] The beneficial effects of the present invention are:

[0040] 1. For this photo-taking and framing printer, through the provided connecting block, students can pull one end of the main swing arm to rotate within the movable shell with the connecting block as the axis, so that the cartridge can be moved out of the protective shell until the main swing arm is perpendicular to the movable shell. Subsequently, move the main swing arm up and down, causing the main swing arm to drive the connecting block to move up and down within the movable shell, thereby solving the problem that the light projection component and the camera can be far away from the printing. The main swing arm can slide up and down, facilitating the adjustment of the size of the light area, making it convenient to read various questions of different sizes and lengths on the test paper. Using the principle of optical adjustable size for near and far, the light area boundary is used to take questions and print. When the film is precisely cut and segmented, the width of the paper to be printed can be visually judged when the light is projected onto the test paper, enabling students to accurately switch between two-inch and three-inch consumables when using the consumables.

[0041] 2. For this photo-taking and framing printer, for the convenience of carrying, the framing head of the wrong-question printer in the prior art is made into a foldable camera. When students do not use it, the camera and the light projection component on the overall device can be put into the protective shell, and the folded overall device is convenient to put into the schoolbag.

[0042] 3. In this photo-taking and framing printer, when the light from the lamp beads illuminates the first convex lens, passes through the film, and then projects onto the test paper through the second, third, and fourth convex lenses, a complete rectangular area is formed. The area within the boundary box of the bright edge is the content that students need to frame. As shown in Figure 5 , the camera can capture the text content within the box for shooting and then perform the printing work. The main swing arm can be adjusted up and down to make the rectangular light area larger or smaller, enabling the recognition of questions with different widths. Moreover, through the telescopic component and the universal adjustment component, the shooting position can be adjusted to meet the requirements of framing and taking photos. Figure 5 As shown, the camera can capture the text content within the box for shooting and then perform the printing work. The main swing arm can be adjusted up and down to make the rectangular light area larger or smaller, enabling the recognition of questions with different widths. And through the telescopic component and the universal adjustment component, the shooting position can be adjusted to meet the requirements of framing and taking photos.

[0043] 4. The telescopic component alone can achieve the telescopic adjustment of the length of the main swing arm. It is not only limited to scanning students' wrong questions. When scanning other larger-sized content, without moving the printer, only by changing the length of the main swing arm through the telescopic component and the lifting of the main swing arm, the scanning of the inner content can be achieved in place. On the one hand, it can avoid the cumbersome work of handling.

[0044] 5. The universal adjustment component alone can achieve 360° free adjustment of the front end of the main swing arm. It is not only limited to the photo recognition of content on the horizontal plane, but also can perform photo recognition on the content of the vertical plane and the arc surface. When recognizing the content of the vertical plane, by changing the angle of the front end of the main swing arm through the universal adjustment component and the coordinated action of the telescopic component, instead of moving the printer and flipping the placement angle of the printer separately, it can be ensured that the content on the vertical plane can be photo recognized according to the original horizontal benchmark at the original placement position, maintaining the consistency of the proportion. And through the universal adjustment component, the angle switching of photo recognition can be changed, and the content on the arc surface can also be photo recognized. By using the coordinated action of the telescopic component and the universal adjustment component, the same-proportion photo recognition of the content on multiple position surfaces can be achieved without moving the position based on the same reference position, ensuring the overall visual coordination of the recognized pictures and achieving unexpected technical effects.

[0061] Embodiment 1: Please refer to Figures 1 - 8 as shown in the figure, this embodiment provides a printer for taking pictures and framing, including a printer base 1, and further including:

[0062] a storage slot 11, a protective shell 13 and a movable shell 14 are arranged in the storage slot 11, and the protective shell 13 is located on the top of the movable shell 14;

[0063] The paper switching button 12 is fixedly installed on the printer base 1;

[0064] The connecting block 15 is movably installed in the movable shell 14. One side of the connecting block 15 is provided with a main rocker arm 2. The main rocker arm 2 further includes:

[0065] The telescopic assembly includes an arm one 21 and an arm two 25. The arm one 21 is fixedly installed on one side of the connecting block 15. A chute 22 is opened in the arm one 21. A slide plate 24 fixed to the arm two 25 is slidably installed in the chute 22. Limiting grooves 23 are opened on both sides of the chute 22. A limiting block 241 fixed to the slide plate 24 is slidably installed in the limiting grooves 23; when the arm two 25 moves away from the arm one 21, the slide plate 24 can slide in the chute 22, and the limiting block 241 slides in the limiting grooves 23 to prevent the slide plate 24 from falling out of the chute 22 and ensure the structural stability of the arm two 25.

[0066] A groove is opened at the bottom of the arm two. A cartridge case is provided in the groove. A light projecting assembly 3 and a camera 4 are provided in the cartridge case.

[0067] Among them, through the provided connecting block 15, students can pull one end of the main rocker arm 2 to rotate in the movable shell 14 with the connecting block 15 as the axis, so that the cartridge case is moved out of the protective shell 13 until the main rocker arm 2 is perpendicular to the movable shell 14. Subsequently, move the main rocker arm 2 up and down, so that the main rocker arm 2 drives the connecting block 15 to move up and down in the movable shell 14, so that the light projecting assembly 3 and the camera 4 can be far away from the printed questions. The main rocker arm 2 can slide up and down, which is convenient for adjusting the size of the light area and convenient for reading various questions of different sizes and lengths on the test paper. Using the principle that the size of the optical system can be adjusted near and far, the boundary line of the light area is used to take questions for printing. When the light is projected onto the test paper, the film 35 can be accurately cut and segmented, and the width of the paper required for printing can be visually judged, so that students can clearly switch accurately between two-inch and three-inch consumables when using the consumables;

[0068] For the convenience of carrying, the viewfinder of the wrong-question printer in the prior art is made into a foldable camera 4. When students do not use it, the camera 4 and the light projecting assembly 3 on the whole device can enter the protective shell 13, and the folded whole device is convenient to put into the schoolbag.

[0069] When the light of the lamp bead 32 illuminating the convex lens one 34 passes through the film 35, and then passes through the convex lens two 36, the convex lens three 37 and the convex lens four 38 and is projected onto the test paper, a complete rectangular area is formed. The area within the boundary box of the bright edge is the content that students need to frame, such as Figure 5As shown, the camera 4 can capture the text content within the square for shooting and then perform the printing work. The main swing arm 2 can be adjusted up and down to make the rectangular light area larger or smaller, and can recognize questions of different widths.

[0070] It further includes a universal adjustment component arranged inside the main swing arm 2, enabling the light projection component 3 and the camera 4 to achieve rotational adjustment. The universal adjustment component includes a universal head 7. One end of the universal head 7 is rotatably arranged inside the first part 26 of the main swing arm 2, and the other end is rotatably arranged inside the second part 27. Both ends of the universal head are spherical structures. The ball head at one end rotates inside the first part 26, and the ball head at the other end is rotatably arranged inside the second part 27. And when an external force is needed to twist the main swing arm 2, the parts of the camera 4 and the light projection component 3 can be rotationally adjusted, so as to be able to adjust the position of the area irradiated on the paper. Combined with the adjustment of the telescopic component, the area and position of the photo-taking viewfinder can be further adjusted.

[0071] The printer in this embodiment is not only applicable to the photo recognition of wrong questions, but also adapted to other applicable scenarios. The telescopic component alone can achieve the telescopic adjustment of the length of the main swing arm 2. It is not limited to scanning the wrong questions of students. When scanning other larger-sized content, there is no need to move the printer. Only by using the telescopic component to change the length of the main swing arm 2 and the lifting of the main swing arm can the scanning of the inner content be achieved in place. On the one hand, it can avoid the cumbersome work of handling. Traditional printers need to move their placement positions to achieve this.

[0072] In addition, the universal adjustment component can achieve 360° free adjustment of the front end of the main swing arm 2. It is not only limited to the photo recognition of content on the horizontal plane, but also can perform photo recognition on the content of the vertical plane and the arc surface. When recognizing the content of the vertical plane, by changing the angle of the front end of the main swing arm 2 through the universal adjustment component and the coordinated action of the telescopic component, without the need to move the printer and flip the placement angle of the printer separately (traditional printers can only perform photo recognition on the content of the horizontal plane. When it is necessary to recognize the content of the non-horizontal plane, the overall placement angle of the printer needs to be changed, which will lead to a change in the reference position compared with the previous position, resulting in a change in the scanning content ratio). Thus, it can ensure that the content on the vertical plane can be photo recognized according to the original horizontal reference at the original placement position, maintaining the consistency of the ratio. And through the universal adjustment component, the angle switching of the photo recognition can be changed, and the content on the arc surface can also be photo recognized. By the individual functions of the telescopic component and the universal adjustment component, and the coordination of the telescopic component and the universal adjustment component, it can achieve the same-proportion photo recognition of the content on multiple position surfaces at the same reference position without moving the position, ensuring the overall visual coordination of the recognized pictures and achieving unexpected technical effects.

[0092] Working principle:

[0093] Students can pull one end of the main rocker arm 2 to rotate within the movable housing 14 with the connecting block 15 as the axis, so that the cartridge is moved out of the protective housing 13 until the main rocker arm 2 is perpendicular to the movable housing 14. Subsequently, move the main rocker arm 2 up and down, so that the main rocker arm 2 drives the connecting block 15 to move up and down within the movable housing 14, so that the light projection assembly 3 and the camera 4 can move away from the printed questions. The main rocker arm 2 can slide up and down, which is convenient for adjusting the size of the light area and facilitating the reading of various questions of different sizes and lengths on the test paper. Using the principle that the size of the optical system can be adjusted remotely, the boundary line of the light area is used for question taking and printing. When the light is projected onto the test paper, the film 35 can be accurately cut and segmented to visually judge the width of the paper to be printed, so that students can clearly switch between two-inch and three-inch consumables when using the consumables;

[0094] For easy carrying, the viewfinder of the wrong-question printer in the prior art is made into a foldable camera 4. When not in use by students, the camera 4 and the light projection assembly 3 on the whole device can be placed into the protective housing 13. The folded whole device is convenient to put into the schoolbag.

[0095] When the light from the lamp bead 32 illuminating the first convex lens 34 passes through the film 35, and then passes through the second convex lens 36, the third convex lens 37 and the fourth convex lens 38 and is projected onto the test paper, a complete rectangular area is formed. The area within the boundary box of the bright edge is the content that students need to view. As Figure 5 shown, the camera 4 can capture the text content within the box for shooting and then perform the printing work. The main rocker arm 2 can be adjusted up and down to make the rectangular light area larger or smaller, and questions of different widths can be recognized.

[0096] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
