Description

Technical Field

[0001] This utility model relates to the field of camera equipment technology, and in particular to a children's camera that uses sheet-like printing paper. Background Technology

[0002] A children's camera is a shooting tool specifically designed for children. It features bright colors and cute designs, often incorporating cartoon or animal elements to attract children's interest. It can cultivate children's interest in exploring the outside world, stimulate their imagination, and is easy to operate with large, few buttons, an intuitive interface, and basic functions such as taking photos, recording videos, and simple filters. Some models also include games or drawing functions.

[0003] In recent years, as more and more commercial technologies have been applied from commercial applications to consumer products, the scale of the home market has gradually increased, leading to a gradual increase in demand for toy products such as children's cameras. As a result, children's cameras have also upgraded from the original structural imaging technology to thermal printing imaging technology, which has a higher quality of photographic images.

[0004] Most existing thermal printers use roll-fed paper, which is placed in the paper tray inside the printer for continuous printing. Similarly, children's cameras integrate a similar structure for continuous printing. However, current camera thermal paper uses a high-toughness, high-strength paper base coated with microparticle powder, then sealed with a film. Therefore, compared to ordinary thermal paper, camera thermal paper is more durable and stronger, less prone to tearing, and requires a serrated blade for cutting. In actual use, after the thermal paper has formed an image inside the camera, it can be manually cut using the serrated blade above the output tray. However, because the gear next to the camera roll meshes with the motor, and the support points on the camera's movable cover mainly rely on the meshing of the transmission gear and motor, as well as the engagement of the bottom of the movable cover with the recess in the housing, the gears and motor bear most of the tension during the cutting process. Over time, the motor will gradually reach its fatigue yield point due to this tension, ultimately resulting in misalignment of the motor's printing positioning, inaccurate imaging, or even failure to roll out the photographic paper.

[0005] The patent with patent number CN 221669973 U aims to protect the movement by optimizing the structure of the back cover. However, it still requires manual cutting with the assistance of a serrated blade, which is inconvenient and results in uneven edges on the cut photos. Utility Model Content

[0006] The purpose of this invention is to address one of the above-mentioned defects and provide a children's camera that uses sheet-like printing paper.

[0007] The objective of this utility model is achieved through the following means:

[0008] A children's camera using sheet-like printing paper includes a camera body, a printing assembly within the camera body, a paper feed roller, and a paper tray for holding multiple sheets of sheet-like printing paper. The paper tray contains a paper pressing structure for pressing the multiple sheets of sheet-like printing paper together. The paper pressing structure includes a paper pressing element for pressing the sheet-like printing paper together and cooperating with the paper feed roller to transport the sheet-like printing paper to the printing assembly.

[0009] As a preferred embodiment, the paper pressing component is a pressure plate, and the camera body is provided with an inner frame, which includes a first part and a second part. The first part and the second part are fastened together to form the paper compartment. The pressure plate is disposed in the first part, and the pressure plate and the first part are separately disposed. One end of the pressure plate is rotatably connected to the first part, and an elastic structure is provided between the pressure plate and the first part to make the other end of the pressure plate always have the tendency to press the sheet of printing paper toward the paper feed roller.

[0010] As a preferred embodiment, an angle rotation limiting structure is provided between the pressure plate and the first part to restrict the small-angle rotation of the non-free end of the pressure plate.

[0011] As a preferred embodiment, the angle rotation limiting structure includes a limiting protrusion, which is laterally disposed on the side of the first part facing the pressure plate. An active space is formed between the limiting protrusion and the first part for the non-free end of the pressure plate to be inserted. This active space allows the non-free end of the pressure plate to rotate at a small angle. The pressure plate is rotatably connected to the first part through the cooperation between the non-free end of the pressure plate and the limiting protrusion.

[0012] As a preferred embodiment, the elastic structure is a reset spring that tilts toward the first part, and the pressure plate is provided with a clearance groove corresponding to the reset spring.

[0013] As a preferred embodiment, a horizontal movement limiting structure is provided between the reset spring and the first part to prevent the reset spring from moving horizontally.

[0014] As a preferred embodiment, the reset spring is integrally formed and connected with the pressure plate. The horizontal movement limiting structure includes a first limiting block and a first limiting groove corresponding to the first limiting block. The first limiting block is disposed on the side of the first part facing the pressure plate. The reset spring is provided with the first limiting groove. During assembly, the first limiting block passes through the first limiting groove. The cooperation between the first row of limiting blocks and the first limiting groove prevents the reset spring from moving in the horizontal direction, thereby preventing the pressure plate from moving in the horizontal direction.

[0015] As a preferred embodiment, a paper-pressing limiting structure is provided between the pressure plate and the first part to restrict the pressure plate from rotating toward the paper feed roller.

[0016] As a preferred embodiment, the paper pressing and limiting structure includes a buckle and a corresponding locking groove. The first limiting buckle is located on the side of the first part facing the pressure plate, and the locking groove is located on the side of the pressure plate facing the first part. During assembly, the buckle is fastened in the locking groove, and the first part limits the rotation angle of the pressure plate toward the paper feeding roller through the cooperation between the buckle and the locking groove.

[0017] As a preferred embodiment, a pressure plate opening limiting structure is provided between the pressure plate and the first part to restrict the pressure plate from rotating toward the first part. The pressure plate opening limiting structure includes a second limiting block and a second limiting groove corresponding to the second limiting block. The second limiting block is located on the side of the pressure plate facing the first part, and the second limiting block is located on the side of the first part facing the pressure plate. The height of the second limiting block is greater than the depth of the second limiting groove. The free end of the first limiting block abuts against the bottom of the second limiting groove to prevent the pressure plate from continuing to open.

[0018] The beneficial effects of this invention are as follows: by setting a paper tray and a paper pressing structure on the camera body for loading multiple sheets of sheet-like printing paper, the sheet-like printing paper in the paper tray is fixed by the paper pressing structure and fed by the paper feeding roller, and then the sheet-like printing paper is printed by the thermal print head. The structure is simple and does not require manual cutting of the printing paper during use. Attached Figure Description

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] To facilitate understanding, the present invention will now be described in further detail with reference to specific implementation examples, but this is not intended to limit the present invention.

[0032] like Figure 1-9 As shown, this utility model discloses a children's camera using sheet-like printing paper 20, including a camera body 10. The camera body 10 contains a photography component (not shown) and a printing component 12. The printing component 12 includes a paper feed roller 121, a thermal print head 122, a printing roller 123 opposite to the thermal print head 122, and a drive motor 124 for driving the paper feed roller 121 and the printing roller 123 to rotate. The drive motor 124 drives the paper feed roller 121 and the printing roller 123 through a gear set 125. The sheet printing paper 20 is a sheet of paper with a thermal printing layer coated on a paper base. The camera body 10 has a paper tray 11 for holding multiple sheets of sheet printing paper 20. The structure of the paper tray 10 for sheet printing paper 20 is different from that of the paper tray for roll printing paper. The paper tray 11 has a paper pressing structure for pressing multiple sheets of sheet printing paper 20 together. The paper pressing structure includes a paper pressing component, which presses the sheet printing paper 20 together and, in cooperation with the paper feed roller 121, feeds the sheet printing paper 20 to the printing assembly 12. By setting up a paper tray 11 and a paper pressing structure on the camera body 10 to hold multiple sheets of sheet printing paper 20, the paper pressing structure fixes the sheet printing paper 20 in the paper tray 11, and the paper is fed through cooperation with the paper feed roller 121. Then, the thermal print head 122 completes the printing of the sheet printing paper 20. The structure is simple, and manual cutting of the printing paper is not required during use.

[0033] The principles of photographic imaging by the photographic component and the transmission of the electrical signals of the imaging to the printing component for printing are existing technologies and are the same as those of the patent with patent number CN109462725B, so they will not be described in detail.

[0034] In this embodiment, the camera body 10 is provided with an inner frame 13, which includes a first part 131 and a second part 132. The first part 131 and the second part 132 are fastened together to form the paper tray 11. A paper pressing component is provided in the first part 131. The tray door 14 and the printing outlet 15 of the paper tray 11 are respectively provided on the left and right sides of the camera body 10.

[0035] In this embodiment, the paper pressing component is a pressure plate 111, which is separately disposed from the first part 131. One end of the pressure plate 111 is rotatably connected to the first part 131, and an elastic structure is provided between the pressure plate 111 and the first part 131 to ensure that the other end of the pressure plate 111 always has the tendency to press the sheet-shaped printing paper 20 toward the paper feed roller 121.

[0036] In this embodiment, the elastic structure is a reset spring 1111 that tilts toward the first part 131, and the pressure plate 111 is provided with a clearance groove 1115 corresponding to the reset spring 1111.

[0037] In practical applications, the elastic structure is not limited to the reset spring 1111, but can also be a spring, which controls the pressure plate 111 to press the sheet-like printing paper 20.

[0038] An angle rotation limiting structure is provided between the pressure plate 111 and the first part 131 to restrict the small-angle rotation of the non-free end of the pressure plate 111. The angle rotation limiting structure includes a limiting protrusion 1311, which is laterally arranged on the side of the first part 131 facing the pressure plate 111. An active space is formed between the limiting protrusion 1311 and the first part 131 for the non-free end of the pressure plate 111 to be inserted. This active space allows the non-free end of the pressure plate 111 to rotate at a small angle. The pressure plate 111 is rotatably connected to the first part 131 through the cooperation of the non-free end of the pressure plate 111 and the limiting protrusion 1311. The structure is simple and easy to assemble.

[0039] The reset spring 1111 is integrally formed with the pressure plate 111. 3D printing, injection molding, stamping, and casting are all mature integral forming technologies, and therefore will not be described in detail. In this embodiment, the pressure plate 111 is provided with a clearance groove 1115. The reset spring 1111 extends from the side wall of the clearance groove 1115 and curves towards the first portion 131. By integrally forming the reset spring 1111 with the pressure plate 111, installation is convenient.

[0040] A horizontal movement limiting structure is provided between the reset spring 1111 and the first part 131 to prevent the reset spring 111 from moving horizontally. The horizontal movement limiting structure includes a first limiting block 1312 and a first limiting groove 1112 corresponding to the first limiting block 1312. The first limiting block 1312 is located on the side of the first part 131 facing the pressure plate 111. The reset spring 1111 has the first limiting groove 1112. During assembly, the first limiting block 1312 is inserted into the first limiting groove 1112. The cooperation between the first limiting block 1312 and the first limiting groove 1112 prevents the reset spring 1111 from moving horizontally, thereby preventing the pressure plate 111 from moving horizontally.

[0041] A paper-pressing limiting structure is provided between the pressure plate 111 and the first part 131 to restrict the rotation of the pressure plate 111 toward the paper feed roller 121. The paper-pressing limiting structure includes a buckle 1313 and a corresponding locking groove 1113. The first limiting buckle 1313 is located on the side of the first part 131 facing the pressure plate 111, and the locking groove 1113 is located on the side of the pressure plate 111 facing the first part 131. During assembly, the buckle 1313 is fastened into the locking groove 1113, and the rotation angle of the pressure plate 111 toward the paper feed roller 121 is limited by the cooperation between the buckle 1313 and the locking groove 1113. By setting the buckle 1313 and the locking groove 1113, the rotation angle of the pressure plate 111 toward the paper feed roller 121 is limited, thereby preventing the pressure plate 111 from pressing obvious indentations into the sheet printing paper 20.

[0042] During the loading of sheet printing paper 20, the sheet printing paper 20 pushes against the pressure plate, causing the pressure plate 111 to gradually open. However, if too much sheet printing paper 20 is loaded into the paper tray 11 at once, the pressure plate 111 will open at too large an angle, causing deformation between the pressure plate 111 and the reset spring 1111. After deformation, the pressure plate 111 cannot press the sheet printing paper 20 against the paper feed roller 121, thus failing to feed the sheet printing paper 20 to the thermal print head 122, resulting in the inability to print photos. Therefore, a restriction is provided between the pressure plate 111 and the first part 131 to prevent the pressure plate 111 from moving towards the first part. The pressure plate opening limiting structure 131 includes a second limiting block 1114 and a second limiting groove 1314 corresponding to the second limiting block 1114. The second limiting block 1114 is located on the side of the pressure plate 111 facing the first part 131, and the height of the second limiting block 1312 is greater than the depth of the second limiting groove 1314. The free end of the first limiting block 1312 abuts against the bottom of the second limiting groove 1314 to prevent the pressure plate 111 from opening further. By setting the second limiting block 1114 and the second limiting groove 1314 to limit the rotation angle of the pressure plate 111 towards the first part 131, the pressure plate 111 can be prevented from opening excessively during paper loading, and the elasticity of the reset spring 1111 can be prevented from failing due to the excessive opening of the pressure plate 111.

[0043] In this embodiment, the angle rotation limiting structure, the horizontal movement limiting structure, the paper pressing limiting structure, and the pressure plate opening limiting structure are arranged sequentially along the feeding direction of the sheet printing paper 20. The cooperation of the angle rotation limiting structure, the horizontal movement limiting structure, and the paper pressing limiting structure prevents the pressure plate 111 from moving in the vertical and horizontal directions, thereby preventing the pressure plate 111 from detaching from the first part 131 during use.

[0044] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
