Description

Technical Field

[0001] The utility model relates to the technical field of a printer, and in particular to a printer based on an internal space structural design and a light source integration module thereof. Background Art

[0002] In the prior art, a printer includes a housing, a photosensitive component, a light source component, and multiple toner cartridges. The housing has a storage tank. The photosensitive component, light source component, and multiple toner cartridges are respectively disposed within the storage tank. The photosensitive component includes a photosensitive drum, the light source component includes a light source (such as a light-emitting diode or laser element), and each toner cartridge contains toner and a developing roller. The light source component of the light source assembly exposes the image to be printed to the photosensitive drum. The developing roller of the toner cartridge deposits toner onto the exposed surface of the photosensitive drum. Finally, the toner on the photosensitive drum surface is transferred to paper.

[0003] In existing printer structures, the multiple photosensitive drums of the photosensitive assembly are spaced apart, and each toner cartridge is assembled within the spaced apart arrangement, corresponding to each photosensitive drum. The light source assembly is positioned on the inner bottom of the cover, corresponding to the position of each photosensitive drum. When the printer cover is closed onto the housing, the light source components of the light source assembly can be positioned between the toner cartridges, i.e., the light source assembly corresponds to each photosensitive drum, allowing the light source components to expose the corresponding photosensitive drums. It must be emphasized that existing printers, with the light source positioned inside the cover, not only have poor internal space utilization but also make maintenance (such as clearing paper jams) difficult.

[0004] However, when closing the cover onto the housing, the light source assembly at the bottom of the cover is easily misaligned with the toner cartridge in the housing due to poor structural design, resulting in a high probability of the cover not closing smoothly. Therefore, the toner cartridge is usually reduced in size to allow for relative movement of the light source assembly. However, this also results in a reduced amount of toner that can be stored in the toner cartridge, leading to the problem of frequent replacement of the toner cartridge when needed. Furthermore, if a paper jam occurs, a structural design that is more convenient for clearing the jam is required. Therefore, in terms of the existing technology, there is a real need to propose a solution that can solve the above problems. Utility Model Content

[0040] For details on the implementation of this utility model, please refer to Figures 1 to 6 , Figure 1 This is a structural stereogram of the printer of the utility model. Figure 2 It is a three-dimensional diagram of the decomposed structure. Figure 3 It is a three-dimensional diagram of part of the structure. Figure 4 It is a partially cutaway side view. Figure 5 Is a partially decomposed stereogram with Figure 6 This is a partially exploded side view. As shown in the figure, this embodiment provides a printer 1, including a housing 11, a photosensitive assembly 12, a light source assembly 13, multiple toner cartridges 14, and a cover assembly 15. The housing 11 has a receiving slot 111. The photosensitive assembly 12 is disposed in the receiving slot 111. The photosensitive assembly 12 includes multiple photosensitive drums 121 and a photosensitive bracket 122. The multiple photosensitive drums 121 are spaced apart from the photosensitive bracket 122. The light source assembly 13 is disposed on the photosensitive assembly 12. The light source assembly 13 includes multiple light source components 131 and a light source bracket 132. The multiple light source components 131 are spaced apart from the light source bracket 132. The multiple light source components 131 correspond to the multiple photosensitive drums 121, respectively. Multiple toner cartridges 14 are inserted between the photosensitive assembly 12 and the light source assembly 13. The multiple toner cartridges 14 correspond to the multiple photosensitive drums 121 and the multiple light source components 131, respectively. The cover assembly 15 is disposed on the housing 11 . The cover assembly 15 covers the receiving groove 111 . The cover assembly 15 is located on the plurality of toner cartridges 14 .

[0041] Please refer to Figure 5 and Figure 6 In this embodiment, the photosensitive bracket 122 further includes a handle 1221, two side brackets 1222, and a fixed bracket 1223. The handle 1221 is fixed to one end of each of the side brackets 1222, and the fixed bracket 1223 is fixed to the other end of each of the side brackets 1222. The two ends of each photosensitive drum 121 are disposed on the two side brackets 1222, and the multiple photosensitive drums 121 are positioned between the handle 1221 and the fixed bracket 1223. The multiple photosensitive drums 121 are spaced apart by a first interval 120. Furthermore, the photosensitive bracket 122 further includes a fixed rod 1224, the two ends of which are respectively passed through the two ends of the two side brackets 1222.

[0042] Furthermore, in this embodiment, the multiple light sources 131 can each be comprised of a light-emitting diode print head (LPH) to achieve power conservation, durability, and high efficiency. The light source bracket 132 also includes a first bracket 1321 and two second brackets 1322. The first bracket 1321 is secured at both ends to one end of each of the two second brackets 1322. Each light source 131 is attached to both ends of the two second brackets 1322. The multiple light sources 131 are positioned on one side of the first bracket 1321, and are spaced apart by a plurality of second intervals 130. Furthermore, the light source bracket 132 also includes two hooks 1323, each of which is disposed at either end of the first bracket 1321.

[0043] As described above, the two hook members 1323 of the light source bracket 132 are hooked and fixed to the ends of the fixing rod 1224 of the photosensitive bracket 122, so that the light source bracket 132 is fixed above the photosensitive bracket 122. The light source member 131 of the light source bracket 132 illuminates the photosensitive drum 121 of the photosensitive bracket 122. The plurality of first compartments 120 and the plurality of second compartments 130 are interconnected, and the plurality of toner cartridges 14 are assembled in the plurality of first compartments 11 and the plurality of second compartments 12, respectively. In other words, the plurality of toner cartridges 14 are located between each combination of the light source member 131 and the photosensitive drum 121.

[0044] In this embodiment, the internal structural design of the printer 1 is improved by positioning the light source assembly 13 within the gap between the photosensitive assembly 12 and the toner cartridge 14. This avoids the structural issues typically encountered in conventional systems, where the light source assembly at the bottom of the cover plate cannot be properly positioned relative to the toner cartridge within the receiving slot. Furthermore, this improved internal structural design of the printer 1 reduces the impact of the toner cartridge 14 on the receiving slot 111 of the housing 11, further increasing the size of the toner cartridge 14.

[0045] Please refer again Figure 4 and Figure 6 Each toner cartridge 14 includes a toner storage tank 141 and a developing roller 142. The toner storage tank 141 has an outlet 1411. The developing roller 142 is pivotally mounted on the outlet 1411 of the toner storage tank 141. The developing roller 142 abuts against the surfaces of the multiple photosensitive drums 121. Furthermore, the printer 1 includes a charging assembly 17. The charging assembly 17 corresponds to one side of the multiple photosensitive drums 121 and provides an electric charge to the surfaces of the multiple photosensitive drums 121.

[0046] As described above, the housing 11's receiving slot 111 defines a paper feed path, with the plurality of photosensitive drums 121 positioned along the paper feed path. The cover assembly 15 includes a paper output port 150, with the output end of the paper feed path connected to the paper output port. Furthermore, the printer 1 includes a paper storage tray 16, a transfer roller assembly, and a heating assembly. The paper storage tray 16 is located at the bottom of the housing 11 and is connected to the input end of the paper feed path. The transfer roller assembly corresponds to one side of the plurality of photosensitive drums 121, with the paper feed path passing between the plurality of photosensitive drums 121 and the transfer roller assembly. The heating assembly is positioned along the paper feed path, and between the transfer roller assembly and the paper output port 150.

[0047] In this embodiment, the printer 1 primarily performs the following steps: The first step is charging, where the charging assembly 17 charges the surfaces of the multiple photosensitive drums 121, imparting a positive charge to the surfaces. The second step is exposure, where the light source 131 of the light source assembly 13 irradiates light onto the multiple photosensitive drums 121. The positive charge on the surfaces of the photosensitive drums 121 illuminated by the light source 131 disappears, leaving the areas illuminated by the light source 131 as the image or text to be printed. The third step is development, where the positively charged toner in the toner storage tank 141 is deposited onto the surfaces of the multiple photosensitive drums 121 by the developing roller 142. Due to electrostatic forces, the toner is attracted to areas of the photosensitive drums 121 that lack a positive charge (i.e., the areas illuminated by the light source 131). Areas not illuminated by the light source 131, which themselves have a positive charge, repel the toner. Consequently, the toner forms the desired text or image on the surfaces of the multiple photosensitive drums 121.

[0048] As described above, the fourth step is transfer, where the paper is output from the paper storage cassette 16 onto the paper transport path. The paper passes between multiple photosensitive drums 121 and a transfer roller assembly. The transfer roller assembly has a negative charge on its surface, pressing the paper's surface against the photosensitive drums 121 while the other surface of the paper is simultaneously pressed against the negatively charged transfer roller assembly. The positively charged toner on the photosensitive drums 121 is then attracted by the transfer roller assembly and printed onto the paper. The fifth step is fixing, where the previously printed toner-coated paper is pushed through a heating assembly. The heating assembly uses high temperature and high pressure to fuse the toner to the paper's fibers. Finally, the printed paper is transported outward through the paper outlet 150 of the cover assembly 15.

[0049] Please refer again Figure 5 , and further see Figure 7 and Figure 8 , Figure 7 This is a side view of the structure of the printer of the present invention. Figure 8It is a side view of another structure. The light source bracket 132 also includes two gear members 1324, and the two gear members 1324 are respectively arranged at the two ends of the second bracket 1322 away from the two hook members 1323. The housing 11 has two gear parts 112, and the two gear members 1324 are engaged and rotated with the two gear parts 112, wherein the two gear members 1324 limit the rotation of the two gear parts 112, and the light source bracket 132 of the light source assembly 13 maintains a fixed angle relative to the notch of the accommodating groove 111. In this way, the two gear members 1324 and the two gear parts 112 rotate relative to each other, and the two gear members 1324 and the two gear parts 112 produce a damping and limiting effect on each other, so that the two gear members 1324 and the two gear parts 112 can be fixed to maintain a fixed angle between the light source bracket 132 and the notch of the accommodating groove 111.

[0050] Furthermore, the cover assembly 15 includes a plate 151 and two support rods 152. One side of the plate 151 is pivotally mounted on the housing 11. One end of the two support rods 152 is supported on either side of the housing 11, while the other ends of the two support rods 152 are supported on either side of the plate 151. The support rods 152 have wedge-shaped damping rings, which create slight resistance during the opening process. When the plate 151 of the cover assembly 15 is opened continuously and reaches its apex, a latch engages, preventing the plate 151 from falling due to its own weight. This provides auxiliary support and maintains a fixed angle between the plate 151 of the cover assembly 15 and the notch of the accommodating slot 111. To close the plate 151 of the cover assembly 15, a slight pressure is applied to disengage the latch. The plate 151 then slowly descends due to the greater downward resistance created by the wedge-shaped damping rings, preventing the plate 151 from falling too quickly and potentially injuring fingers.

[0051] See also Figures 7 to 9 , Figure 7 This is a side view of the structure of the printer of the utility model. Figure 8 This is a disassembled side view. Figure 9 Another disassembled side view. As shown in the figure, in this embodiment, if the user wants to repair or replace the internal parts of the photosensitive component 12, such as replacing the photosensitive drum, the user can first open the plate 151 of the cover assembly 15. After the plate 151 is opened, the support rods 152 on both sides will automatically support the plate 151 and the housing 11. A plurality of toner cartridges 14 are arranged and assembled in the accommodating groove 111 of the housing 11, and the plurality of toner cartridges 14 are sequentially taken out from the first gap 120 of the photosensitive bracket 122 and the second gap 130 of the light source bracket 132 (as shown in FIG. Figure 5 Remove the toner cartridge 14).

[0052] Furthermore, first remove the two hook members 1323 of the light source bracket 132 from the ends of the fixed rod 1224 of the photosensitive bracket 122, so that the two hook members 1323 are separated from the ends of the fixed rod 1224. Since the light source bracket 132 is provided with a torsion spring, the hook members 1323 can bounce up after being separated from the fixed rod 1224 (such as Figure 8 At this point, the user can perform simple repairs or replace parts on the photosensitive component 12. Furthermore, by lifting the photosensitive component 12 with the handle 1221, the photosensitive component 12 can be directly removed from the receiving groove 111 at a specific angle relative to the notch of the receiving groove 111, allowing the user to easily repair or replace parts on the photosensitive component 12.

[0053] In addition, when the user wants to troubleshoot the problem of irregular paper output or paper jam in the printer 1, after opening the plate 151 of the cover assembly 15, the user only needs to lift the grip 1221 of the photosensitive component 12 with one hand, and then the photosensitive component 12 and the light source component 13 fixed on the photosensitive component 12 can be lifted together, so that the photosensitive component 12 and the light source component 13 maintain an angle with the notch of the receiving groove 111 at the same time, so that the mechanism and path of the paper printing output inside the receiving groove 111 of the printer 1 can be directly exposed. At this point, the problem of irregular paper output or paper jam can be solved. The above process does not require any disassembly steps, such as removing the toner cartridge 14 or disassembling the light source assembly 13 from the photosensitive bracket 122.

[0054] Please refer again Figure 6 , and also see Figure 10 and Figure 11 , Figure 10 yes Figure 8 A magnified image of area A and Figure 11 yes Figure 9 An enlarged view of area B. As shown in the figure, in this embodiment, the photosensitive bracket 122 also includes a photosensitive shaft 1225, which is pivotally disposed in the pivot hole 110 of the housing 11, and the pivot hole 110 has an opening 1101. The user can further lift the photosensitive bracket 122 by lifting the handle 1221, and then tilt the photosensitive bracket 122 to a removal angle. At the removal angle of the photosensitive bracket 122, the photosensitive shaft 1225 will also rotate accordingly, so that the outer contour of the shaft of the photosensitive shaft 1225 can correspond to the opening 1101 of the pivot hole 110. In the process of removing the photosensitive bracket 122, the photosensitive shaft 1225 will be removed along the opening 1101 of the pivot hole 110. In this way, the photosensitive component 12 can be removed from the accommodating slot 111 of the housing 11 without disassembling the light source bracket 132.

[0055] In this embodiment, the printer of the present invention provides a light source integration module 10, which is composed of the photosensitive component 12, the light source component 13 and multiple toner cartridges 14 as described above; through an integrated design, the light source component 13 is set in the assembly gap between the photosensitive component 12 and the toner cartridge 14, and is integrated into a light source integration module 10 that is easy to assemble and disassemble, thereby improving the internal structural design of the printer.

[0056] In summary, the present invention avoids the structural issues that often arise in conventional printers, where the light source assembly at the bottom of the cover plate cannot be smoothly closed relative to the toner cartridge in the receiving slot. Furthermore, due to the improved internal structural design of the printer, the size of the toner cartridge can be further increased. Furthermore, if paper jams inside the printer, the gear design of the light source bracket allows the light source integration module to maintain a fixed open angle relative to the notch of the housing's receiving slot, allowing the user to directly remove the jammed paper or remove the photosensitive assembly from the housing's receiving slot without removing the light source bracket.
