Description

Technical Field

[0001] The utility model relates to the technical field of imaging equipment (such as printers and copiers), and in particular to a tray structure for imaging equipment and the imaging equipment. Background Art

[0002] Imaging devices, such as printers and copiers, are equipped with a tray for stacking paper and a feeding mechanism for feeding the stacked paper. The stacked paper is fed one by one onto the imaging unit at predetermined times, forming an image on the paper. The tray requires a structure to limit the paper's position, ensuring that it is properly gripped and transported during the printing process, thereby maintaining print quality and stability.

[0003] For example, the Chinese utility model patent with patent number CN202420694486.2 (publication number CN221892833U) discloses a paper clamping and limiting device for a printer. The paper clamping and limiting device includes: a tray, which is arranged at the paper inlet of the printer body; a longitudinal adjustment component, which is a limit frame arranged in the middle of the tray, the middle part of the limit frame is rotatably connected to a gear, and the outer walls on both sides of the gear are meshed and connected with a first rack and a second rack, and the first rack and the second rack are slidably connected to the limit frame. This patent can achieve the longitudinal positioning of the paper by pushing the first limit plate, and then by adjusting the lateral adjustment component and pushing the second limit plate, the paper can be limited in the lateral direction.

[0004] It can be seen that the operation of this patent when limiting the paper is rather cumbersome. The paper needs to be positioned longitudinally first, and then positioned transversely. Moreover, the paper may not be adjusted into place in one go, and multiple adjustments are required, which makes the operation rather cumbersome. In addition, multiple components need to work together to adjust and position the paper transversely and longitudinally, involving many components. Utility Model Content

[0005] The first technical problem to be solved by the present invention is to provide a tray structure for an imaging device that is convenient for positioning paper in view of the current state of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide an imaging device using the above tray structure in view of the current status of the existing technology.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a tray structure for an imaging device, comprising

[0008] Tray, defines the paper feeding direction of the tray as the backward direction;

[0009] A limiting component is provided on the tray and is used to limit the position of the paper on the tray;

[0010] The limiting assembly comprises

[0011] The limiting seats have top, side and rear open limiting areas, two limiting seats are arranged in left and right direction, the side of two limiting seats are oppositely arranged, the distance between two limiting seats and the rear edge of the tray is the same, the limiting area of two limiting seats is used for placing the two corners of the paper from top to bottom and limiting.

[0012] In order to make the limiting seat have the above limiting area, the cross section of each limiting seat is L-shaped, including a width limiting plate extending in front and back direction and a length limiting plate extending in left and right direction, the length limiting plate is connected with the front end of the width limiting plate, the width limiting plate and the length limiting plate form the limiting area, the distance between two width limiting plates is matched with the width of the paper to be placed.

[0013] In order to further facilitate the corner of the paper to be limited in the limiting area, the wall surface of the top of the limiting seat is inclined to the limiting area from top to bottom, the inclined surface plays a guiding role, when the paper is not placed in the correct position, the corner of the paper will be regularized into the limiting area through the guidance of the inclined surface.

[0014] In order to be able to limit different sizes of paper, two limiting seats are detachably installed on the tray, so that the distance between two limiting seats in left and right direction and the distance between the limiting seat and the rear edge of the tray are adjustable, the limiting seat is installed in different positions to limit different sizes of paper.

[0029] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0030] like Figures 1 to 8 As shown, the imaging device of this preferred embodiment includes a body 1 and a tray structure, which includes a tray 2. The body 1 is provided with a paper inlet 11. The tray 2 is located at the front side of the body 1 and extends in the front-to-back direction. The tray 2 is connected to the paper inlet 11, and the paper feeding direction of the tray 2 is defined as the rearward direction. This is prior art and will not be further described here.

[0031] The tray structure also includes a limiting component, which is arranged on the tray 2 and is used to limit the paper on the tray 2 and adjust the skew of the paper to ensure the quality of the printed image.

[0032] like Figure 2 、 3 As shown in Figures 4 and 5, the limiting assembly includes two limiting seats 3, each limiting seat 3 having a limiting area 31 with open top, side and rear portions. The two limiting seats 3 are spaced apart in the left-right direction, the side openings of the two limiting seats 3 are arranged opposite to each other, and the two limiting seats 3 are at the same distance from the rear edge of the tray 2. The limiting areas 31 of the two limiting seats 3 are respectively used for placing the two corners of the paper to be placed from top to bottom and limiting them inside.

[0033] The wall surface on the top of the limiting seat 3 is a slope 32 which inclines from top to bottom towards the limiting area 31, and the slope 32 plays a guiding role. When the paper is not placed in the correct position, the corner of the paper will be regularized into the limiting area 31 through the guidance of the slope 32. As long as the two corners of the paper are placed against the limiting area 31 of the limiting seat 3, the limiting of the paper in the transverse direction (width direction) and the longitudinal direction (length direction) is realized at the same time, which is convenient and fast, and the limiting position is fixed. Once placed in position, the correct use position is achieved after installation, and there is no need to adjust.

[0034] In the embodiment, the cross section of each limiting seat 3 is L-shaped, including a width limiting plate 33 extending in the front-rear direction and a length limiting plate 34 extending in the left-right direction. The length limiting plate 34 is connected to the front end of the width limiting plate 33 (the "front end" refers to the end of the width limiting plate 33 away from the body 1), and the width limiting plate 33 and the length limiting plate 34 enclose the limiting area 31. The length limiting plate 34 is located between the two width limiting plates 33, and the spacing between the two width limiting plates 33 is adapted to the width of the paper to be placed to limit the transverse direction of the paper. If the imaging device is of the structure as shown in the embodiment, the spacing between the length limiting plate 34 and the rear edge of the tray 2 is not limited. In the embodiment, the front part of the paper is located on the tray 2 before feeding, and the rear part of the paper is located in the body 1 through the paper inlet 11. Of course, the spacing between the length limiting plate 34 and the rear edge of the tray 2 can also be not less than the length of the paper to be placed (the rear edge of the tray 2 refers to the edge close to the paper inlet 11). In this structure, the imaging device is of the structure as shown in the embodiment, and the whole paper is located on the tray 2 before feeding. Figure 1

[0035] As shown in Figure 4 , 5 , 6, the two limiting seats 3 are detachably installed on the tray 2, so that the spacing between the two limiting seats 3 in the left-right direction and the spacing between the limiting seat 3 and the rear edge of the tray 2 are adjustable. The limiting seat 3 is installed at different positions to limit different sizes of paper.

[0036] The tray 2 is provided with a plurality of rib strips 21 which are spaced apart in the left-right direction. Each rib strip 21 extends in the front-rear direction, and each two rib strips 21 are installed as a group. There are at least two installation groups, and the two limiting seats 3 of the limiting assembly are detachably installed on the two rib strips 21 of the same installation group.

[0037] Each rib strip 21 is provided with a positioning hole 22 for positioning the limiting seat 3. The spacing between the two rib strips 21 of different installation groups in the left-right direction is different, and the spacing between the positioning holes 22 on the two rib strips 21 of the same installation group from the rear edge of the tray 2 is the same. The spacing between the positioning holes 22 on the rib strips 21 of different installation groups from the rear edge of the tray 2 is different.

[0038] ​In the production of the ribs 21, the left and right spacing between the ribs 21 and the spacing between the positioning holes 22 and the rear edge of the tray 2 are adapted to the size of the paper, and the ribs 21 function like a scale. By installing the limiting seats 3 on different ribs 21, the left and right spacing between the two limiting seats 3 and the front and back spacing between the limiting seats 3 and the rear edge of the tray 2 can be adjusted to limit different sizes of paper. However, the front and back spacing between the two limiting seats 3 and the rear edge of the tray 2 is always the same no matter how the adjustment is made.

[0039] The positioning holes 22 extend through the corresponding ribs 21 in the left and right directions. Each limiting seat 3 is provided with a transversely arranged mounting plate 35 which is located beside the ribs 21 and in the limiting area 31. The mounting plate 35 is provided with a mounting portion 36 which includes a support arm 361 extending in the left and right directions and a buckle 362 provided at the free end of the support arm 361. The fixed end of the support arm 361 is fixedly connected to the mounting plate 35. The buckle 362 can pass through or come out of the positioning hole 22. When the buckle 362 passes through the positioning hole 22, the buckle 362 reversely buckles against the wall surface of the rib 21 which faces away from the mounting plate 35.

[0040] In this embodiment, the positioning holes 22 extend in the front and back directions. The mounting portion 36 on each mounting plate 35 has two portions which are arranged in the front and back directions. Correspondingly, the positioning holes 22 also have two portions. At least the support arm 361 of one mounting portion 36 can be deflected in the front and back directions. In the state that the back support arm 361 abuts against the back wall surface of the back positioning hole 22 and the front support arm 361 abuts against the front wall surface of the front positioning hole 22, the limiting seat 3 is limited relative to the corresponding rib 21.

[0041] The positioning of the limiting seat 3 is realized in the front and back directions by the two support arms 361 and in the left and right directions by the mounting plate 35 and the buckle 362. When the limiting seat 3 needs to be removed, a force is applied to one of the support arms 361 to make the support arm 361 deflect. The buckle 362 corresponding to the support arm 361 can then come out of the positioning hole 22. Then the limiting seat 3 is moved so that the buckle 362 corresponding to the other support arm 361 also comes out of the positioning hole 22, thereby realizing the removal of the limiting seat 3. When the limiting seat 3 needs to be installed, one of the support arms 361 is first passed through the corresponding positioning hole 22. The buckle 362 corresponding to the support arm 361 reversely buckles against the wall surface of the rib 21. Then a force is applied to the other support arm 361 to make the support arm 361 deflect. The buckle 362 corresponding to the support arm 361 is passed through the corresponding positioning hole 22 and reversely buckles against the wall surface of the rib 21. One of the support arms 361 can be deflected in the front and back directions, or both of the support arms 361 can be deflected in the front and back directions.

[0042] In use, the limiting seat 3 is adjusted in position according to the paper type to be used, and the rib 21 and the positioning hole 22 arranged thereon can ensure correct positioning of the paper in the length and width directions. Figure 1 the mounting position of the limiting seat 3 corresponding to A4 paper, Figure 7 the mounting position of the limiting seat 3 corresponding to B5 paper, Figure 8 the mounting position of the limiting seat 3 corresponding to A5 paper.
