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 memory and improve 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 notebook, 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: 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.

[0004] 2. For the printer that scans and extracts characters, when students scan the text of the test paper, there are problems such as missing characters, missing questions, repeated scanning, resulting in missing characters or repeated questions in printing.

[0005] 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.

[0006] 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.

[0007] In view of this, we propose a printer for taking pictures and framing scenes. Summary of the Invention

[0008] 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.

[0009] In view of this, the present invention provides a printer for taking pictures and framing scenes, including a printer base, and further including: A storage groove, in which a protective shell and a movable shell are provided, and the protective shell is located on top of the movable shell; A paper switching button, which is fixedly installed on the printer base; A connecting block, which is movably installed in the movable shell. One side of the connecting block is provided with a main rocker arm, and the main rocker arm further includes: A telescopic component, which includes Arm 1 and Arm 2. Arm 1 is fixedly installed on one side of the connection block. A chute is opened in Arm 1. A slide plate fixed to Arm 2 is slidably installed in the chute. Limit grooves are opened on both sides of the chute. Limit blocks fixed to the slide plate are slidably installed in the limit grooves. A groove is opened at the bottom of the main swing arm. A cartridge case is provided in the groove. A light projection component and a camera are provided in the cartridge case. A universal adjustment component is provided in the main swing arm, enabling the light projection component and the camera to be rotationally adjusted. The universal adjustment component includes a universal head. One end of the universal head is rotatably provided in the first part of the main swing arm, and the other end is rotatably provided in the second part.

[0010] In this technical solution, through the provided connection block, students can pull one end of the main swing arm to rotate in the movable shell with the connection block as the axis, so that the cartridge case is 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, so that the main swing arm drives the connection block to move up and down in the movable shell, thereby enabling the light projection component and the camera to be far away from the printing problem. The main swing arm can slide up and down, facilitating the adjustment of 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 optics can be adjusted in size from near to far, the edge line of the light area is used for question taking and printing. When the light is projected onto the test paper, the film can be accurately cut and segmented, and the width of the paper to be printed can be visually judged, enabling students to clearly switch between two-inch and three-inch consumables when using the consumables. For easy carrying, the viewfinder 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 enter the protective shell, and the folded overall device is convenient to put into the schoolbag.

[0011] When the light illuminating Convex Lens 1 passes through the film, and then passes through Convex Lens 2, Convex Lens 3, and Convex Lens 4 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 can identify questions of different widths.

[0012] In the above technical solution, further, the light projection component includes: A protective shell, which is provided in the cartridge case. A lamp bead and an inner shell are provided in the protective shell. Convex Lens 1, a film, Convex Lens 2, Convex Lens 3, and Convex Lens 4 are sequentially provided in the inner shell from top to bottom.

[0013] In this technical solution, when the light from the lamp beads illuminates the first convex lens and passes through the film, and then passes through the second, third, and fourth convex lenses and is projected onto the test paper, a complete rectangular area is formed.

[0014] In the above technical solution, further, a transparent and smooth glass is provided at the bottom of the cartridge and below the fourth convex lens and the camera.

[0015] In this technical solution, it is ensured that the transparent and smooth glass can protect 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.

[0016] In the above technical solution, further, one end of the main swing arm penetrates through the connecting block and extends into the printer base. A fixed column is fixedly installed in the printer base and below the connecting block. 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.

[0017] In this technical solution, when the main swing arm is perpendicular to the printer base, the tension spring tightly pulls one end of the main swing arm to prevent the other end of the main swing arm from moving downward.

[0018] In the above technical solution, further, both the protective shell and the movable shell are fixed to the inner wall of the storage groove by a plurality of screws, and the cartridge is fixed to the inner wall of the groove by a plurality of bolts.

[0019] In this technical solution, it is ensured that the structures of the protective shell and the movable shell in the storage groove are stable, and the structure of the cartridge in the groove is stable.

[0020] In the above technical solution, further, the protective shell is snap-fitted with the cartridge. The inner shell is fixed to the inner wall of the protective shell by a plurality of screws, and the camera is fixed to the cartridge by a plurality of screws.

[0021] In this technical solution, it is ensured that the protective shell can be snapped into the cartridge, facilitating the disassembly and installation of the protective shell and the cartridge, and ensuring the structural stability of the inner shell and the protective shell, as well as the structural stability of the camera and the cartridge.

[0022] In the above technical solution, further, the first convex lens is snap-fitted with the inner shell, and the top of the first convex lens is a planar structure, while the bottom of the first convex lens is an arc-shaped structure.

[0023] In this technical solution, it is ensured that the light emitted by the lamp beads can pass through 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.

[0024] In the above technical solution, further, the cross-section of the film is a circular structure, and the middle of the film is a rectangular structure.

[0025] In this technical solution, when the light is projected onto the test paper during the precise cutting and segmentation of the film, the width of the paper to be printed can be visually judged, enabling students to accurately switch between two-inch and three-inch consumables when using them.

[0026] In the above technical solution, further, both the upper and lower sides of the second convex lens and the third convex lens are arc-shaped structures, the top of the fourth convex lens is an arc-shaped structure, and the bottom of the fourth convex lens is a flat structure.

[0027] In this technical solution, it is ensured that the light energy 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.

[0028] 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.

[0029] 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.

[0030] The beneficial effects of the present invention are: 1. For this photo-taking and view-finding 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 are too close to the printing. The main swing arm can slide up and down, facilitating the adjustment of the size of the light area and making it convenient to read various questions of different sizes and lengths on the test paper. Using the principle of optical size adjustment for near and far, the edge of the light area is used to take questions for printing. When the light is projected onto the test paper during the precise cutting and segmentation of the film, the width of the paper to be printed can be visually judged, enabling students to accurately switch between two-inch and three-inch consumables when using them.

[0031] 2. For this photo-taking and view-finding printer, for the convenience of carrying, the view-finding head of the existing wrong-question printer 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 placed into the protective shell, and the folded overall device is convenient to put into a schoolbag.

[0032] 3. For this photo-taking and view-finding printer, when the light illuminating the first convex lens by the lamp beads 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. The area within the boundary box of the bright edge is the content that students need to view, such as Figure 5As shown, the camera can capture the text content within the square 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, which can recognize questions of different widths. Moreover, through the telescopic component and the universal adjustment component, the shooting position can be adjusted to meet the needs of framing and taking pictures.

[0033] 4. The telescopic component alone can realize the telescopic adjustment of the length of the main swing arm. It is not only limited to scanning the wrong questions of students. 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 can the scanning of the inner content be achieved in place. On the one hand, it can avoid the cumbersome work of handling.

[0034] 5. The universal adjustment component alone can realize the 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 to achieve, so as to ensure that the content on the vertical plane can be photo recognized according to the original horizontal reference on 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 coordination of the telescopic component and the universal adjustment component, the same-proportion photo recognition of the content on multiple position surfaces can be realized without moving the position on the premise of the same reference position, ensuring the overall visual coordination of the recognized pictures and achieving unexpected technical effects.

[0042] Embodiment 1: Please refer to Figures 1 - 8 the figure shown. The present embodiment provides a printer for taking pictures and framing, including a printer base 1, and further including: 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; a paper switching button 12, the paper switching button 12 is fixedly installed on the printer base 1; a connecting block 15, the connecting block 15 is movably installed in the movable shell 14, and a main rocker arm 2 is arranged on one side of the connecting block 15. The main rocker arm 2 further includes: The telescopic component includes arm one 21 and arm two 25. Arm one 21 is fixedly installed on one side of the connecting block 15. A sliding groove 22 is formed in arm one 21. A sliding plate 24 fixed to arm two 25 is slidably installed in the sliding groove 22. Limiting grooves 23 are formed on both sides of the sliding groove 22. Limiting blocks 241 fixed to the sliding plate 24 are slidably installed in the limiting grooves 23. When arm two 25 moves away from arm one 21, it is ensured that the sliding plate 24 can slide in the sliding groove 22 and the limiting blocks 241 can slide in the limiting grooves 23, preventing the sliding plate 24 from falling off the sliding groove 22 and ensuring the structural stability of arm two 25.

[0043] A groove is formed at the bottom of the arm two. A cartridge case is provided in the groove. A light projecting component 3 and a camera 4 are provided in the cartridge case.

[0044] Among them, through the provided connecting block 15, students can pull one end of the main swing arm 2 to rotate within the movable housing 14 with the connecting block 15 as the axis, so that the cartridge case is moved out of the protective housing 13 until the main swing arm 2 is perpendicular to the movable housing 14. Subsequently, the main swing arm 2 is moved up and down, causing the main swing arm 2 to drive the connecting block 15 to move up and down within the movable housing 14, so that the light projecting component 3 and the camera 4 can be far away from the printed questions. The main swing arm 2 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, lengths and widths on the test paper. Using the principle that the size of the light can be adjusted remotely by optics, the boundary line of the light area is used to take questions and print. When the light is projected onto the test paper, the film 35 can be accurately cut and segmented, and the width of the paper to be printed can be visually judged, enabling students to accurately switch between two-inch and three-inch consumables when using the consumables. For the convenience of carrying, the viewfinder of the existing wrong-question printer is made into a foldable camera 4. When students do not use it, the camera 4 and the light projecting component 3 on the overall device can be placed into the protective housing 13. The folded overall device is convenient to put into a schoolbag.

[0045] When the light illuminating the convex lens one 34 by the lamp bead 32 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, as Figure 5 shown. The camera 4 can capture the text content within the box for shooting and then carry out the printing work. The main swing arm 2 can be adjusted up and down to make the rectangular light area larger or smaller, and different-width questions can be recognized.

[0046] It further includes a universal adjustment component, which is arranged inside the main swing arm 2, enabling the light projection component 3 and the camera 4 to be rotationally adjusted. 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 required to twist the main swing arm 2, the camera 4 and the light projection component 3 can be rotationally adjusted, so that the position of the area irradiated on the paper can be adjusted. In cooperation with the adjustment of the telescopic component, the area and position of the photographing viewfinder can be further adjusted.

[0047] The printer in this embodiment is not only applicable to the photographing and recognition of wrong questions, but also adapted to other applicable scenarios. The telescopic component alone can realize 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 contents, there is no need to move the printer. Only by adjusting the length of the main swing arm 2 and the lifting of the main swing arm through the telescopic component can the scanning of the inner contents be achieved. On the one hand, the cumbersome work of handling can be avoided. Traditional printers need to move their placement positions to achieve this.

[0048] In addition, the universal adjustment component can realize the 360° free adjustment of the front end of the main swing arm 2. It is not only limited to the photographing and recognition of contents on the horizontal plane, but also the contents on the vertical plane and the arc surface can be photographed and recognized. When recognizing the contents on 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, there is no need to move the printer and flip the placement angle of the printer separately to achieve it (traditional printers can only photograph and recognize the contents on the horizontal plane. When it is necessary to recognize the contents on non-horizontal planes, 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 be ensured that the contents on the vertical plane can be photographed and 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 photographing and recognition can be changed, and the contents on the arc surface can also be photographed and recognized. By the independent function of the telescopic component combined with the independent function of the universal adjustment component, and the coordination of the telescopic component and the universal adjustment component, it is possible to achieve the same-proportion photographing and recognition of the contents 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.

[0067] Working principle: 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, causing the main rocker arm 2 to drive the connecting block 15 to move up and down within the movable housing 14, so that the light projection component 3 and the camera 4 can move away from the printed questions. The main rocker arm 2 can slide up and down, facilitating the adjustment of the size of the light area and making it convenient to read various questions of different sizes, lengths, and widths on the test paper. Using the principle of optical size adjustment for near and far, the boundary line of the light area is used for question printing. When the light projected by the light beads 32 illuminates the convex lens 34, passes through the film 35, and then passes through the convex lenses 36, 37, and 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 the student needs to frame. As shown in the figure, 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, enabling the recognition of questions of different widths. 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 component 3 on the overall device can be placed into the protective housing 13, and the folded overall device is convenient to put into a schoolbag.
