Description

Technical Field

[0001] This invention relates to the field of printing equipment, and more specifically to a paper tray and a printer. Background Technology

[0002] Some existing printer paper tray structures have a lifting plate inside the tray. An elastic element lifts the lifting plate, enabling subsequent paper feeding and separation. The lifting plate has extensions on both sides that engage with inclined tracks inside the machine. When the paper tray is pulled out, the extended sections of the lifting plate are pressed down by the tracks to level the lifting plate, facilitating paper loading. However, if this extension-track approach is continued to be used for larger capacity paper trays, a problem arises: pulling out an empty paper tray requires significant force, negatively impacting the user experience. This is because a larger capacity paper tray means heavier paper. During paper feeding, the elastic element needs to provide elasticity, and the heavier paper requires even greater elasticity. Therefore, when the paper tray is empty, pulling it out along the tracks converts the vertical elasticity into horizontal resistance, requiring considerable force and resulting in a poor user experience. Summary of the Invention

[0015] Option 7, based on Options 1 to 6, further includes a third biasing member. The limiting member is provided with a driving part. When the lifting paperboard moves to the fixed position, it presses against the driving part to move the limiting part to the paper-laying position. The two ends of the third biasing member act on the limiting member and the compartment body respectively, and apply a force to the limiting member to move the limiting part to the limiting position.

The rotating member has a clearance slope and a contact surface adapted to abut against and contact with the pressing member. The contact surface is further away from the fourth biasing member relative to the clearance slope.

[0020] The two ends of the sixth biasing member act on the fastening member and the chamber respectively, so as to apply a force to the fastening member to make it rotate in the direction of fastening with the chamber;

[0021] The locking member is movably connected to the compartment body. The locking member is adapted to engage with the inclined surface of the rotating member or the fastening member so that the limiting part rotates to the limiting position and allows the fastening member to engage with the compartment body under the action of the sixth biasing member.

The limiting component includes a rotating component, a fastening component, a fifth biasing component, and a sixth biasing component. The rotating component is rotatably connected to the chamber body about a first axis and is provided with the limiting portion. The fastening component is rotatably connected to the rotating component about a third axis perpendicular to the first axis, and is positioned in a direction parallel to the third axis. The fastening component and the rotating component are mutually limited. The fastening component is adapted to rotate relative to the rotating component to engage or disengage from the chamber body in a direction parallel to the third axis. The fastening component is provided with a driving portion. When the lifting plate moves to the fixed position, it is adapted to press against the driving portion to make the fastening component rotate relative to the rotating component to disengage from the chamber body. The two ends of the fifth biasing component act on the rotating component and the chamber body respectively to engage or disengage from the chamber body. When the component disengages from the compartment body, the limiting part rotates to the paper-laying position; the two ends of the sixth biasing member act on the fastening member and the compartment body respectively, applying a force to the fastening member to rotate it in the direction of engaging with the compartment body; the locking member is movably connected to the compartment body, and the locking member is adapted to engage with the inclined surface of the rotating member or the fastening member, so that the limiting part rotates to the limiting position, and allows the fastening member to engage with the compartment body under the action of the sixth biasing member, and is adapted to move to disengage from the inclined surface engagement with the rotating member or the fastening member, so that the limiting part rotates to the paper-laying position; the two ends of the seventh biasing member act on the compartment body and the locking member respectively, applying a force to the locking member to move it in the direction of disengaging from the inclined surface engagement with the rotating member or the fastening member; the locking member has a locking end adapted to protrude from the compartment body.

[0026] The locking end is adapted to cooperate with the machine body so that the locking member cooperates with the inclined surface of the rotating member or the fastening member. In the direction in which the paper tray is inserted into the machine body, the operating part and the locking end are arranged in sequence.

[0027] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0028] A paper bin includes a bin body, a lifting board, a limiting member, and a first biasing member.

[0029] The first biasing element acts on both ends of the compartment and the lifting plate respectively to apply a lifting force to the lifting plate. The lifting plate is movably connected to the compartment to facilitate paper lifting during operation. The lifting plate is adapted to move to a fixed position under hand pressure. In the fixed position, the lifting plate is detachably connected to the compartment to stop, preventing it from being lifted by the first biasing element. This lifting plate has eliminated the extended sections on both sides that cooperate with the machine body and does not cooperate with the track, making it easier to pull out. In terms of user operation, after pulling out the lifting plate and before feeding paper, the user needs to manually press the lifting plate down to the fixed position. After connecting with the compartment, paper can be fed onto the lifting plate. The lifting plate is detachably connected to the compartment so that it can be returned to the working state where paper can be lifted after feeding.

[0030] Because the extended sections on the left and right sides have been removed, after the paper tray is pulled out, the lifting plate is in a state of free movement under the force of the first biasing member. If there is still paper on top, the paper may be pushed out and misaligned, or the lifting plate may move away from the predetermined working position under the action of the first biasing member. By setting a limiting member that is movably connected to the tray body and has a limiting part, the limiting part is adapted to move in the limiting position. When it is in the limiting position, the limiting part is located on the lifting path of the lifting plate, so that when the paper tray is pulled out, the remaining paper or lifting plate is pressed against the limiting part under the action of the first biasing member, thus preventing the above-mentioned problems. However, when the limiting part is in the limiting position, it will prevent the user from placing paper on the lifting plate. Therefore, the limiting part is also adapted to move in the paper-dispensing position. When in the paper-dispensing position, the limiting part is located outside the lifting path of the lifting plate, thus not obstructing paper dispensing and making operation more convenient. In use, after the lifting plate is in a fixed position and connected to the tray body, and the limiting part is in the paper-dispensing position, paper can be dispensed. Attached Figure Description

[0070] refer to Figures 1-12 A printer includes a body and a paper tray, the paper tray being adapted to be inserted into the body.

[0071] The machine body is equipped with printing components such as a print head, paper feed roller, and paper separation roller.

[0072] The paper hopper is used to store paper and press the paper against the separating roller.

[0073] The paper bin includes a bin body 1, a paper lifting board 2, a limiting component 3, a first biasing component 4, and a third biasing component 5.

[0074] refer to Figure 2 , Figure 3 , Figure 5The storage unit 1 includes a base 11, a locking component 12, a second biasing component 13, and a paper width adjusting component 14.

[0075] The base 11 forms the main frame of the compartment 1, used for mounting and supporting the corresponding parts. (Reference) Figure 1 The length direction of the base 11 is defined as the first direction 81 (which is also the direction in which the paper tray inserts or exits the machine), and the width direction is defined as the second direction 82, which is perpendicular to the first direction 81. (Reference) Figure 5 The base 11 has a first wall 111 protruding from the bottom wall. The first wall 111 is used to install the second biasing member 13. A first mounting post 1111 extending along the second direction 82 is provided on the first wall 111. A limiting hole 112 is provided on the bottom wall to limit the movement path of the locking member 12, preventing the locking member 12 from disengaging from the base 11. (Reference) Figure 3 , Figure 6 A first exposure hole 113 is provided on the side wall of the base 11 for the operating part 124 of the card 12 to be exposed along the second direction 82.

[0076] refer to Figure 3 , Figure 5 , Figure 6 The locking member 12 is mounted on the base 11. A second mounting post 121 extending along a second direction 82 is provided on the side of the locking member 12 near the first wall 111 for mounting a second biasing member 13. The locking member 12 is adapted to move relative to the base 11 between a locking position and a clearance position. In this embodiment, the locking member 12 is slidably connected to the base 11; in other embodiments, it may be rotatably connected to the base 11. The locking member 12 has a first inclined surface 122, which extends along a vertical direction 83 and is inclined along a second direction 82, wherein the vertical direction 83 is perpendicular to the first direction 81 and the second direction 82. The locking member 12 has a limiting block 123, which is adapted to extend into a limiting hole 112 and to slide within the limiting hole 112 along the second direction 82. The limiting block 123 restricts the sliding stroke of the limiting hole 112. The limiting block 123 has a locking hole 1231 located below the first inclined surface 122. The locking hole 1231 has a limiting surface 1232 parallel to the first direction 81 and the second direction 82. The limiting surface 1232 is a certain distance from both the bottom surface of the locking member 12 and the base 11 to accommodate the locking portion 21 of the lifting plate 2. (Reference) Figure 6 The locking member 12 is provided with an operating portion 124 adapted to be exposed in the base 11. The operating portion 124 is exposed through a first exposure hole 113 to be adapted to be operated or to cooperate with the body to move the locking member 12 to a clearance position. In this embodiment, the operating portion 124 is adapted to cooperate with the body to move the locking member 12 to a clearance position. (See reference) Figure 2At least one of the operating part 124 and the body is provided with a second inclined surface 1241. The second inclined surface 1241 is inclined relative to the first direction 81 and faces forward. In this embodiment, the operating part 124 is provided with a second inclined surface 1241.

[0077] refer to Figure 5 The two ends of the second biasing member 13 act on the locking member 12 and the seat 11 respectively to apply a force to the locking member 12 to move it to the locking position. Specifically, the second biasing member 13 is a spring, one end of which is sleeved on the first mounting post 1111 and abuts against the first wall 111, and the other end is sleeved on the second mounting post 121 and abuts against the locking member 12 to apply a force to the locking member 12 along the second direction 82.

[0078] refer to Figure 2 The paper width adjusting member 14 is movably connected to the base 11 to correspond to the paper width. In this embodiment, the paper width adjusting member 14 is slidably connected to the base 11 along the second direction 82. The paper width adjusting member 14 is provided with an adjusting wall 141 extending along the vertical direction 83 to abut against the side wall of the paper, thereby accommodating different paper widths. There can be two paper width adjusting members 14, which are connected to a gear via a rack and pinion, so that the rotation of the gear can move the two paper width adjusting members 14 closer together or further apart. (Reference) Figure 10 , Figure 9 The paper width adjusting member 14 is provided with a receiving cavity 142. The receiving cavity 142 has a first opening 1421 above it to expose the limiting part 31 (described below) of the limiting member 3, and also has a second opening 1422. The second opening 1422 faces the first direction 81 and is used to expose the driving part 33 (described below) of the limiting member 3.

[0079] The lifting plate 2 is movably connected to the housing 1 and is adapted to move to a fixed position. In this embodiment, the lifting plate 2 is rotatably connected to the front side of the seat 11 about an axis parallel to the second direction 82. The rear end of the lifting plate 2 is adapted to move (rotate) to a fixed position under hand pressure. When the lifting plate 2 is in the fixed position, it is adapted to be detachably connected to the housing 1 to stop at the fixed position. Specifically, in this embodiment,

[0080] refer to Figure 5 , Figure 8 The lifting plate 2 includes a latching part 21, which includes a first plate 211 and a second plate 212 connected to each other. The first plate 211 and the second plate 212 are approximately L-shaped. The first plate 211 extends in a vertical direction 83, and the second plate 212 is perpendicular to the first plate 211 and is horizontal. When the lifting plate 2 rotates to a fixed position, the second plate 212 is adapted to abut against the first inclined surface 122, cooperating with the inclined surface of the latching member 12, so that the latching member 12 slides to the avoidance position. Figure 5(In the direction of the downward arrow), the locking member 12 moves closer to the first wall 111, compressing the second biasing member 13 to store energy until it slides to the avoidance position. At this time, the sliding of the locking member 12 stops, and the locking part 21 passes over the first inclined surface 122 (the part that mates with its inclined surface) and enters the locking hole 1231. When the second plate 212 is located in the locking hole 1231, the second biasing member 13 releases energy, causing the locking member 12 to slide towards the locking position until the locking member 12 abuts against the first plate 211. At this time, the locking member 12 is in the locking position. Under the action of the first biasing member 4 (described below), the second plate 212 abuts against the limiting surface 1232, so that the locking part 21 and the locking member 12 abut against each other in the paper lifting direction, so that the paper lifting plate 2 is in a fixed position and remains stopped. Here, inclined surface mating refers to the fact that the two mating objects are connected by at least one inclined surface (arc surface) so that the direction of the force is changed.

[0081] When the paper tray is inserted into the machine body, the operating part 124 cooperates with the machine body, causing the locking piece 12 to move to the clearance position. At this time, the second plate 212 is misaligned with the limiting surface 1232. Under the action of the first biasing member 4, the second plate 212 disengages from the locking hole 1231 and rises upward to disengage from the locking piece 12, thus achieving disassembly and allowing normal use during the printing process. The detachable connection between the lifting plate 2 and the tray 1 means that after being connected and stopped with the tray 1, the two can be disengaged through certain measures, including snap-fit, magnetic connection, or connection via fasteners. Besides the above-mentioned forms, snap-fit ​​can also be achieved by inserting pins through the tray 1 and the lifting plate 2.

[0082] refer to Figure 4 The two ends of the first biasing member 4 act on the chamber body 1 and the lifting plate 2 respectively to apply a lifting force to the lifting plate 2. Under the action of the lifting force, the paper abuts against the separating roller, or the second plate 212 abuts against the limiting surface 1232, or the lifting plate 2 or the paper on it abuts against the limiting part 31 of the limiting member 3 (described below). In this embodiment, the lower end of the first biasing member 4 abuts against and acts on the seat body 11, and the upper end abuts against and acts on the bottom surface of the lifting plate 2.

[0083] refer to Figure 9 The limiting member 3 is movably connected to the housing 1. Preferably, the limiting member 3 is movably connected to the paper width adjusting member 14 to limit the paper width. The limiting member 3 is partially located within the receiving cavity 142 to protect it, and the rotation range of the limiting member 3 is also limited by the cavity wall of the receiving cavity 142 to prevent it from dislodging from the predetermined position under bias. In this embodiment, reference is made to... Figures 10-12 The limiting member 3 and the paper width adjusting member 14 of the compartment 1 are rotatably connected about a first axis 341 parallel to the first direction 81. In other embodiments, they can also be connected by sliding or other means.

[0084] refer to Figures 10-12The limiting member 3 includes a limiting part 31, a connecting wall 32, a driving part 33, and a rotating wall 34. The limiting part 31 and the rotating wall 34 are substantially parallel. The limiting part 31 extends from the first opening 1421 and is adapted to move between the limiting position and the paper-laying position. (Reference) Figure 10 When the limiting part 31 is in the limiting position, the bottom surface of the limiting part 31 is parallel to the first direction 81 and the second direction 82, and is located on the paper lifting path of the paper lifting board 2 to limit the paper lifting board 2 or the paper on the paper lifting board 2. (Refer to...) Figure 11 When the paper is in the paper-laying position, the limiting part 31 is located outside the paper-laying path of the paper-laying board 2, so as not to limit the paper-laying board 2 or the paper on the paper-laying board 2, facilitating the placement of paper from above the paper tray onto the paper-laying board 2; Reference Figure 12 The connecting wall 32 is connected to a limiting part 31 and a rotating wall 34 at its two ends, respectively. The rotating wall 34 is parallel to the limiting part 31. The end of the rotating wall 34 facing away from the connecting wall 32 is used to rotate with the paper width adjusting member 14 of the storage body 1 around the first axis 341. The driving part 33 extends along the first direction 81 and protrudes from the connecting wall 32, so that there is a gap between it and the first axis 341 to generate torque. Figure 9 The drive part 33 is adapted to extend from the second opening 1422 so that the lifting paperboard 2 is adapted to press against the drive part 33 when it moves to the fixed position, so that the limiting member 3 rotates about the first axis 341 so that the limiting part 31 rotates to the paper placement position.

[0085] refer to Figure 10 The two ends of the third biasing member 5 act on the limiting member 3 and the paper width adjusting member 14 of the compartment 1 respectively, and apply a force to the limiting member 3 to move the limiting part 31 to the limiting position. In this embodiment, an upward force is applied to the limiting member 3 so that the limiting member 3 automatically resets.

[0086] Initially, the paper tray is located inside the machine body. The paper lifting board 2 lifts the paper normally under the action of the first biasing member 4. The limiting part 31 of the limiting member 3 is in the limiting position under the action of the third biasing member 5. The operating part 124 of the locking member 12 is in the avoidance position because it cooperates with the machine body.

[0087] When the paper tray is pulled out, the lifting plate 2 or the paper on it abuts against the limiting part 31 of the limiting member 3 under the action of the first biasing member 4, preventing the lifting plate 2 from leaving the predetermined position or preventing the paper from being disordered. The operating part 124 of the locking member 12 disengages from the machine body. Under the action of the second biasing member 13, the locking member 12 is in the locking position. At this time, the user presses down on the lifting plate 2 by hand, causing it to rotate towards the fixed position. The lifting plate 2 and the inclined surface of the locking member 12 cooperate, causing the locking member 12 to slide towards the avoidance position. The locking part 21 passes over the part of the locking member 12 that cooperates with its inclined surface. At this time, the second biasing member 13 releases energy, causing the locking member 12 to slide towards the locking position, so that the locking part 21 and the locking member 12 abut against each other in the paper lifting direction, so that the lifting plate 2 is in the fixed position and remains stopped. During this process, the bottom surface of the lifting plate 2 abuts against the driving part 33, causing the limiting part 3 to rotate around the first axis 341, so that the limiting part 31 rotates to the paper-dispensing position, and paper can be dispensed from above the paper tray onto the lifting plate 2 without being blocked by the limiting part 31.

[0088] After the paper is loaded, the paper tray is pushed into the machine body. During the pushing process, the operating end of the locking piece 12 is in cooperation with the machine body, and the locking piece 12 slides to the avoidance position. At this time, the first biasing member 4 can disengage the lifting paperboard 2 from the locking piece 12 and ensure normal lifting. At the same time, after the lifting paperboard 2 rises, it will no longer exert a downward force on the drive part 33. The third biasing member 5 acts on the limiting member 3, so that the limiting part 31 is in the limiting position.

[0089] Compared with existing technologies, this embodiment has the following advantages:

[0090] In one exemplary embodiment, a paper bin includes a bin body 1, a lifting board 2, a limiting member 3, and a first biasing member 4.

[0091] The first biasing member 4 acts on both ends of the compartment body 1 and the lifting plate 2 respectively to apply a lifting force to the lifting plate 2. The lifting plate 2 is movably connected to the compartment body 1 to facilitate paper lifting during operation. The lifting plate 2 is adapted to move to a fixed position under hand pressure. The lifting plate 2 is detachably connected to the compartment body 1 at the fixed position to stop, preventing it from being lifted by the first biasing member 4. The lifting plate 2 has removed the extended sections on both sides that cooperate with the machine body and does not cooperate with the track, making it easier to pull out. In terms of user operation, after pulling out the lifting plate 2 and before putting out the paper, the user needs to manually press the lifting plate 2 down to the fixed position. After connecting to the compartment body 1, paper can be put onto the lifting plate 2. The lifting plate 2 is detachably connected to the compartment body 1 so that it can be restored to the working state where it can lift paper after the paper is put out.

[0092] Because the extended sections on the left and right sides have been removed, after the paper tray is pulled out, the lifting plate 2 is in a state of free movement under the force of the first biasing member 4. If there is still paper on top, the paper may be pushed out and disordered, or the lifting plate 2 may move away from the predetermined working position under the action of the first biasing member 4. By setting a limiting member 3 to be movably connected to the tray body 1 and providing a limiting part 31, the limiting part 31 is adapted to move in the limiting position. When it is in the limiting position, the limiting part 31 is located on the paper lifting path of the lifting plate 2. Thus, when the paper tray is pulled out, the remaining paper or the lifting plate 2 abuts against the limiting part 31 under the action of the first biasing member 4, and the above-mentioned problems will not occur. However, when the limiting part 31 is in the limiting position, it will prevent the user from placing paper on the lifting plate 2. Therefore, the limiting part 31 is also adapted to move in the paper placement position. When it is in the paper placement position, the limiting part 31 is located outside the paper lifting path of the lifting plate 2, so as not to obstruct the paper placement and making the operation more convenient. In use, after positioning the lifting cardboard 2 in a fixed position and connecting it to the storage body 1, and setting the limiting part 31 to the paper-dispensing position, paper can be dispensed.

[0093] In one exemplary embodiment, the lifting plate 2 is adapted to be snapped, magnetically connected, or connected by fasteners to the bin body 1 to stop in a fixed position. The above method achieves a detachable connection, which is simple, convenient, and low in cost.

[0094] In one exemplary embodiment, the tray 1 includes a base 11 and a locking element 12. The paper lifting plate 2 includes a locking part 21. The locking element 12 is installed on the base 11 and is adapted to move relative to the base 11 in a locking position and a clearance position. In the clearance position, it is adapted to allow the locking part 21 to pass over it. In the locking position, the locking part 21 and the locking element 12 abut against each other in the paper lifting direction so that the paper lifting plate 2 is in a fixed position. The paper lifting plate 2 is locked to the tray 1 by the movable locking element 12. Compared with the locking part 21 being adapted to deform to achieve locking, it is not easily damaged, has a longer service life, and is suitable for the frequent paper feeding operations of the printer.

[0095] In one exemplary embodiment, the compartment 1 further includes a second biasing member 13, and the locking part 21 is adapted to engage with the inclined surface of the locking member 12 so that the locking member 12 slides to the avoidance position. Through the inclined surface engagement, the locking member 12 can automatically slide to the avoidance position when the lifting cardboard 2 is pressed down, without the need to operate the locking member 12 separately. At the same time, the two ends of the second biasing member 13 act on the locking member 12 and the seat 11 respectively to apply a force to the locking member 12 to move it to the locking position, so that the locking member 12 automatically resets to engage with the locking part 21, without the need to operate the locking member 12 separately, which is more convenient. In this way, pressing down the lifting cardboard 2 can complete the engagement between the lifting cardboard 2 and the locking member 12, which is simple and convenient.

[0096] In one exemplary embodiment, the locking member 12 is provided with an operating part 124 adapted to be exposed in the base 11. The operating part 124 is adapted to be operated or to cooperate with the machine body to move the locking member 12 to a clearance position, so that when the user operates or the paper tray slides into the machine body, the locking member 12 can be unlocked from the locking part 21, thereby making the lifting board 2 suitable for lifting the paper under the action of the first biasing member 4 during operation. The latter is more convenient to use. When the paper is loaded and the paper tray is reinserted into the machine body, the locking part 21 can be disengaged from the locking member 12 without manual operation, which is more convenient.

[0097] In one exemplary embodiment, the storage compartment 1 includes a base 11 and a paper width adjusting member 14. The paper width adjusting member 14 is movably connected to the base 11 to correspond to the paper width. The limiting member 3 is movably connected to the paper width adjusting member 14 and can be adjusted to correspond to the width of the paper. When the paper width changes, it still allows the paper on the lifting board 2 to be blocked after the paper compartment is pulled out, making it more versatile.

[0098] In one exemplary embodiment, the limiting member 3 is provided with a driving part 33. When the lifting paperboard 2 moves to a fixed position, it presses against the driving part 33 to move the limiting part 31 to the paper release position. During the process of the lifting paperboard 2 pressing down, the limiting member 3 moves automatically, so that there is no need to operate the limiting member 3, which is more convenient. The two ends of the third biasing member 5 act on the limiting member 3 and the compartment 1 respectively, and apply a force to the limiting member 3 to move the limiting part 31 to the limiting position. Thus, when the lifting paperboard 2 is not pressing down the driving part 33, the limiting part 31 can be automatically in the limiting position, that is, when the paper compartment is pulled out, the limiting part 31 is in the limiting position.

[0099] In one exemplary embodiment, the limiting member 3 is rotatably connected to the chamber 1 about the first axis 341, and there is a gap between the driving part 33 and the first axis 341 to generate torque, so that the lifting cardboard 2 is suitable to press against the driving part 33 when it moves to a fixed position, so that the limiting part 31 can rotate to the paper-laying position. This structure is simple and convenient.

[0100] Example 2

[0101] (Same as above) In this embodiment, the limiting member 3 is provided with a driving part 33. The lifting plate 2 is adapted to press against the driving part 33 when it moves to a fixed position, so that the limiting part 31 moves to the paper feeding position; the two ends of the third biasing member 5 act on the limiting member 3 and the bin 1 respectively, and apply a force to the limiting member 3 to make the limiting part 31 move to the limiting position.

[0102] Unlike Embodiment 1, the structure of the limiting member 3 is slightly different in this embodiment.

[0103] refer to Figures 13-17 Specifically, the limiting member 3 includes a pressing member 35, a rotating member 36, and a fourth biasing member 37, as shown in the reference. Figure 14 , Figure 15 The rotating component 36 is rotatably connected to the paper width adjusting component 14 of the storage unit 1 about a first axis 341 parallel to the first direction 81. The rotating component 36 includes a limiting part 31, a connecting wall 32, and a pressing protrusion 361. The upper end of the connecting wall 32 is connected to the limiting part 31, and the lower end is rotatably connected to the paper width adjusting component 14 of the storage unit 1 about a first axis 341 parallel to the first direction 81. The pressing protrusion 361 protrudes from the surface of the connecting wall 32 facing the pressing component 35. The pressing protrusion 361 has a relief slope 3611 and a contact surface 3612 suitable for abutting and connecting with the pressing component 35. The contact surface 3612 is further away from the fourth biasing component 37 relative to the relief slope 3611. The contact surface 3612 can be a plane for greater stability when abutting with the pressing component 35.

[0104] refer to Figure 16 , Figure 17 The two ends of the fourth biasing member 37 act on the adjusting wall 141 of the paper width adjusting member 14 of the rotating member 36 and the paper width adjusting member 14 of the compartment 1, respectively, to apply a force parallel to the second direction 82 to the rotating member 36, so that the rotating member 36 rotates in the direction that positions the limiting part 31 in the paper feeding position, and causes the relief slope 3611 or the abutting surface 3612 to abut against the pressing member 35. When the relief slope 3611 abuts against the pressing member 35, the limiting part 31 is in the paper feeding position; when the abutting surface 3612 abuts against the pressing member 35, the limiting part 31 is in the limiting position.

[0105] refer to Figure 14 The pressing member 35 is rotatably connected to the housing 1 about a second axis 351 perpendicular to the first axis 341, and is provided with a driving part 33, which extends from the second opening 1422 along the first direction 81. The pressing member 35 is adapted to abut against the relief slope 3611 or the abutment surface 3612 so that the limiting part 31 can be located in the paper feeding position or the limiting position.

[0106] refer to Figure 14 The two ends of the third biasing member 5 act on the pressing member 35 and the paper width adjusting member 14 of the compartment 1 respectively, and apply a force along the first direction 81 to the pressing member 35, causing the pressing member 35 to rotate in the direction of abutting the contact surface 3612.

[0107] Initially, the paper tray is located inside the machine body. The paper lifting plate 2 lifts the paper normally under the action of the first biasing member 4. The pressing member 35 abuts against the contact surface 3612 under the action of the third biasing member 5. The rotating member 36 rotates to the limit position. The operating part 124 of the locking member 12 is in the avoidance position because it cooperates with the machine body.

[0108] (Same as above) When the paper tray is pulled out, the lifting plate 2 or the paper on it abuts against the limiting part 31 of the limiting member 3 under the action of the first biasing member 4, to prevent the lifting plate 2 from leaving the predetermined position or to prevent the paper from being disordered. The operating part 124 of the locking member 12 disengages from the machine body. Under the action of the second biasing member 13, the locking member 12 is in the locking position. At this time, the user presses down on the lifting plate 2 by hand, so that it rotates to the fixed position. The lifting plate 2 and the inclined surface of the locking member 12 cooperate, so that the locking member 12 slides to the avoidance position. The locking part 21 passes over the part of the locking member 12 that cooperates with its inclined surface. At this time, the second biasing member 13 releases energy, so that the locking member 12 slides to the locking position, so that the locking part 21 and the locking member 12 abut against each other in the paper lifting direction, so that the lifting plate 2 is in the fixed position and stays stopped.

[0109] During this process, the bottom surface of the lifting board 2 abuts against the driving part 33 of the pressing member 35, causing the pressing member 35 to rotate around the second axis 351 to rotate to correspond with the relief slope 3611. At this time, the rotating member 36 can rotate under the action of the fourth biasing member 37, so that the relief slope 3611 abuts against the pressing member 35, and the limiting part 31 rotates to the paper feeding position, so that paper can be fed from the top of the paper tray onto the lifting board 2 without being blocked by the limiting part 31.

[0110] After the paper is loaded, the paper tray is pushed into the machine body. During the pushing process, the operating part 124 of the locking piece 12, due to its cooperation with the machine body, slides the locking piece 12 to the avoidance position. At this time, the first biasing member 4 can disengage the lifting plate 2 from the locking piece 12 and ensure normal lifting. At the same time, after the lifting plate 2 rises, it will no longer exert a downward force on the driving part 33. The third biasing member 5 acts on the pressing member 35, causing the pressing member 35 to rotate to abut against the abutment surface 3612, and causing the limiting part 31 on the rotating member 36 to rotate to the limiting position. During the subsequent insertion into the paper tray, whether the operating part 124 cooperates with the machine body, i.e., the position of the locking piece 12, does not affect normal use. However, when pulling out, it must not cooperate with the machine body, so that the locking piece 12 is in the locking position.

[0111] Unlike Embodiment 1, this embodiment also has the following beneficial effects:

[0112] In one exemplary embodiment, the limiting member 3 includes a pressing member 35, a rotating member 36, and a fourth biasing member 37. The rotating member 36 is rotatably connected to the chamber 1 about a first axis 341 and is provided with a limiting part 31. The rotating member 36 is provided with a relief slope 3611 and a contact surface 3612 adapted to abut against the pressing member 35. The two ends of the fourth biasing member 37 act on the rotating member 36 and the chamber 1 respectively, so that the relief slope 3611 or the contact surface 3612 abuts against the pressing member 35. When the pressing member 35 abuts, the limiting part 31 is in the paper-laying position. When the abutting surface 3612 abuts against the pressing member 35, the limiting part 31 is in the limiting position. The pressing member 35 is rotatably connected to the storage unit 1 around the second axis 351 perpendicular to the first axis 341. The pressing member 35 is provided with a driving part 33. When the lifting board 2 abuts against the driving part 33, the pressing member 35 rotates to abut against the relief slope 3611, thereby allowing the rotating member 36 to rotate the limiting part 31 to the paper-laying position under the action of the fourth biasing member 37. The two ends of the third biasing member 5 act on the pressing member 35 and the storage unit 1 respectively, and cause the pressing member 35 to rotate in the direction of abutting against the abutting surface 3612. Thus, when the lifting board 2 is not pressing down on the driving part 33, the pressing member 35 can abut against the abutting surface 3612, and the limiting part 31 automatically rotates to the limiting position. The abutting surface 3612 is further away from the fourth biasing member 37 than the yielding slope 3611. The yielding slope 3611 forms a height difference with the abutting surface 3612, resulting in different effects when it abuts against the pressing member 35. On the other hand, the slope on the yielding slope 3611 allows the pressing member 35 to switch freely between abutting against the abutting surface 3612 and abutting against the yielding slope 3611.

[0113] Example 3:

[0114] Unlike Embodiment 1, in this embodiment, the structure of the limiting member 3 and the paper width adjusting member 14 of the compartment 1 are slightly different.

[0115] refer to Figures 18-24 The limiting member 3 includes a rotating member 36, a fastening member 38, a fifth biasing member 391, and a sixth biasing member 392. The rotating member 36 is rotatably connected to the storage compartment 1 about a first axis 341 parallel to the first direction 81. The rotating member 36 has a limiting part 31 and a connecting wall 32. The upper end of the connecting wall 32 is connected to the limiting part 31, and the lower end is rotatably connected to the paper width adjusting member 14 of the storage compartment 1 about the first axis 341 parallel to the first direction 81. (Reference) Figure 19 The rotating part 36 has an inclined block 362 on the side opposite to the fastening part 38. The inclined block 362 protrudes from the connecting wall 32. The inclined block 362 has a third inclined surface 3621. The third inclined surface 3621 faces downward and extends along the vertical direction 83 and is inclined along the second direction 82.

[0116] refer to Figure 22The fastening member 38 is rotatably connected to the rotating member 36 about a third axis 384 perpendicular to the first axis 341. In this embodiment, the third axis 384 is parallel to the second direction 82. The fastening member 38 and the rotating member 36 are mutually positioned along the direction parallel to the third axis 384. In this embodiment, the fastening member 38 and the connecting wall 32 are locked by screws 9 and clamped by the screws 9 and the limiting wall along the second direction 82, so that the fastening member 38 and the rotating member 36 are mutually positioned along the second direction 82.

[0117] refer to Figure 20 The fastening member 38 is adapted to rotate relative to the rotating member 36 to engage or disengage with the compartment 1 in a direction parallel to the third axis 384. Specifically, the fastening member 38 is provided with a first fastening part 381, and a second fastening part 143 protrudes from the first wall surface 1411 of the paper width adjusting member 14 (the surface of the adjusting wall 141 forming the cavity wall of the receiving cavity 142). The second fastening part 143 includes a first part 1431 and a second part 1432, which are vertically connected and form an L-shape. The second part 1432 protrudes from the first part 1431 in the vertical direction 83 and forms an opening above it for the first fastening part 381 to rotate into. When the first fastening part 381 abuts against the first part 1431, the rotation stops, and it is adapted to abut against the second part 1432 in the second direction 82 for limiting. When the first fastening part 381 rotates to a position where it does not correspond to the second part 1432, the two disengage. At this time, the limiting part 31 of the rotating member 36 is allowed to rotate to the paper feeding position.

[0118] refer to Figure 18 The fastener 38 is provided with a drive part 33. When the lifting plate 2 moves to a fixed position, it presses against the drive part 33 so that the fastener 38 rotates relative to the rotating part 36 until it is disengaged from the compartment 1.

[0119] refer to Figure 20 The two ends of the fifth bias member 391 act on the first wall surface 1411 of the paper width adjustment member 14 of the rotating member 36 and the storage body 1, respectively, and apply force to the rotating member 36 in the second direction 82 so that when the fastening member 38 is disengaged from the storage body 1, the limiting part 31 rotates to the paper feeding position.

[0120] refer to Figure 21 The two ends of the sixth biasing member 392 act on the fastening member 38 and the paper width adjusting member 14 of the compartment 1 respectively, and apply force to the fastening member 38 in the first direction 81 to apply a force to the fastening member 38 to make it rotate in the direction of fastening with the compartment 1.

[0121] To enable the fastening component 38 to be installed in a smaller installation environment, the fastening component 38 can be further disassembled. Specifically, the fastening component 38 includes a first component 382 and a second component 383. The first component 382 is provided with a driving part 33. The second component 383 is adapted to engage or disengage from the paper width adjustment component 14 of the compartment body 1 and is limited by the rotating component 36 along the second direction 82. Both the first component 382 and the second component 383 rotate around an axis parallel to the second direction 82 with the paper width adjustment component 14. The first component 382 is adapted to abut against the second component 383 to rotate it until it disengages from the paper width adjustment component 14. The sixth biasing component 392 acts on the second component 383.

[0122] refer to Figure 19 The locking member 6 is movably connected to the paper width adjusting member 14 of the storage compartment 1. In this embodiment, the locking member 6 and the paper width adjusting member 14 of the storage compartment 1 are slidably connected in the vertical direction 83. The locking member 6 is adapted to cooperate with the third inclined surface 3621 of the rotating member 36 so that the rotating member 36 rotates and the limiting part 31 rotates to the limiting position. In this state, the fastening member 38 is also driven by the rotating member 36 to a position that allows the fastening member 38 to fasten with the storage compartment 1 under the action of the sixth biasing member 392. The locking member 6 is adapted to move to disengage from the inclined surface cooperation with the rotating member 36 so that the limiting part 31 can rotate to the paper feeding position.

[0123] The two ends of the seventh biasing member 7 act on the paper width adjusting member 14 and the locking member 6 of the compartment 1 respectively, so as to apply a force to the locking member 6 to make it move in the direction of disengaging from the inclined surface of the rotating member 36;

[0124] In other embodiments, the locking member 6 may also cooperate with the inclined surface of the fastening member 38 to achieve the above-mentioned effect.

[0125] refer to Figure 18 and Figure 24 The locking member 6 is provided with a locking end 61 adapted to protrude from the tray body 1. In this embodiment, the locking end 61 is adapted to protrude from the bottom of the tray body 1 to cooperate with the machine body, so that the locking member 6 disengages from the inclined engagement with the rotating member 36 or the fastening member 38. In the direction in which the paper tray is inserted into the machine body, the operating part 124 and the locking end 61 are arranged in sequence. In other embodiments, the locking end 61 can be operated by hand to achieve the above-mentioned effect.

[0126] Initially, the paper tray is located inside the machine body. The paper lifting plate 2 is lifted normally under the action of the first biasing member 4. Under the action of the sixth biasing member 392, the fastening member 38 is fastened to the tray body 1, keeping the limiting part 31 in the limiting position. The operating part 124 of the locking member 12 is in the avoidance position because it cooperates with the machine body. The locking end 61 of the locking member 6 cooperates with the machine body and slides upward to abut against the third inclined surface 3621.

[0127] When the paper tray is pulled out, the locking member 6 moves downward under the action of the seventh biasing member 7 to disengage from the inclined surface of the third inclined surface 3621. However, since the fastening member 38 is still in the fastening state with the tray body 1, the fifth biasing member 391 cannot perform its function.

[0128] (Same as above) and the paper on the lifting plate 2 or the paper on it is pressed against the limiting part 31 of the limiting part 3 under the action of the first biasing member 4 to prevent the lifting plate 2 from leaving the predetermined position or to prevent the paper from being messed up. The operating end of the locking member 12 is disengaged from the machine body. Under the action of the second biasing member 13, the locking member 12 is in the locking position. At this time, the user presses down on the lifting plate 2 by hand to make it rotate to the fixed position. The lifting plate 2 and the inclined surface of the locking member 12 cooperate to make the locking member 12 slide to the avoidance position. The locking part 21 passes over the part of the locking member 12 that cooperates with its inclined surface. At this time, the second biasing member 13 releases energy, making the locking member 12 slide to the locking position, so that the locking part 21 and the locking member 12 abut against each other in the paper lifting direction, so that the lifting plate 2 is in the fixed position and stays stopped.

[0129] During this process, the bottom surface of the lifting plate 2 abuts against the driving part 33 of the fastening member 38, causing the fastening member 38 to rotate around the third axis 384 until it disengages from the compartment 1. Under the action of the fifth biasing member 391, the rotating member 36 rotates, causing the limiting part 31 to rotate to the paper-dispensing position, so that paper can be dispensed from above the paper compartment onto the lifting plate 2 without being blocked by the limiting part 31. At the same time, the fastening member 38 rotates with the rotating member 36 and disengages from the first wall 111.

[0130] After the paper is loaded, the paper tray is pushed into the machine body. During the pushing process, the locking end 61 first cooperates with the machine body and moves upward so that the locking part 6 cooperates with the third inclined surface 3621, so that the limiting part 31 rotates to the limiting position. At the same time, the fastening part 38 rotates with the rotating part 36 and abuts against the first wall surface 1411 again. At this time, the fastening part 38 is allowed to rotate to fasten with the tray body 1.

[0131] As the paper tray continues to be pushed in, the operating end of the locking piece 12, due to its engagement with the machine body, slides to a clearance position. At this point, the first biasing member 4 disengages the lifting plate 2 from the locking piece 12, ensuring normal lifting. Simultaneously, after the lifting plate 2 rises, it no longer exerts a downward force on the drive unit 33. The sixth biasing member 392 acts on the fastening member 38, causing it to rotate and engage with the tray body 1, keeping the limiting part 31 on the rotating member 36 in the limiting position. Whether the locking end 61 of the locking member 6 engages with the machine body during subsequent insertion does not affect the position of the limiting part 31 when the paper tray detaches from the machine body (it maintains the limiting position under the action of the fastening member 38).

[0132] Unlike Embodiment 1, this embodiment also has the following beneficial effects:

[0133] In one exemplary embodiment, the limiting member 3 includes a rotating member 36, a fastening member 38, a fifth biasing member 391, and a sixth biasing member 392. The rotating member 36 is rotatably connected to the chamber body 1 about a first axis 341 and is provided with a limiting part 31. The fastening member 38 is rotatably connected to the rotating member 36 about a third axis 384 perpendicular to the first axis 341, so that the fastening member 38 is adapted to rotate relative to the rotating member 36 to fasten or disengage from the chamber body 1 in a direction parallel to the third axis 384.

[0134] The limiting part 31 rotates to the paper-laying position: The fastening member 38 is provided with a driving part 33. When the lifting plate 2 moves to the fixed position, it is adapted to press against the driving part 33, so that the fastening member 38 rotates relative to the rotating member 36 until it disengages from the storage compartment 1. The two ends of the fifth biasing member 391 act on the rotating member 36 and the storage compartment 1 respectively, so that when the fastening member 38 disengages from the storage compartment 1, the limiting part 31 rotates to the paper-laying position, so that when the lifting plate 2 is pressed down, the limiting part 31 automatically rotates to the paper-laying position. In this state, the locking member 6 is adapted to move to disengage from the inclined surface engagement with the rotating member 36 or the fastening member 38, so as to allow the limiting part 31 to rotate to the paper-laying position, thereby realizing the above process.

[0135] The limiting part 31 rotates to the limiting position: Since the fastening part 38 and the rotating part 36 are limited along the direction parallel to the third axis 384, when the rotating part 36 rotates along the first axis 341, the fastening part 38 also rotates along the first axis 341 with the rotating part 36. The part that fastens with the compartment 1 may not correspond to the corresponding mating part on the compartment 1. Therefore, the rotating part 36 needs to be rotated back to re-enter the fastening state. The locking member 6 is movably connected to the compartment 1. The locking member 6 is adapted to engage with the inclined surface of the rotating member 36 or the fastening member 38 so that the limiting part 31 rotates to the limiting position. In this position, when the lifting cardboard 2 is not pressing down on the driving part 33, the two ends of the sixth biasing member 392 act on the fastening member 38 and the compartment 1 respectively to apply a force to the fastening member 38 to rotate in the direction of fastening with the compartment 1. Therefore, the fastening member 38 is re-fastened to the compartment 1 under the action of the sixth biasing member 392. When the fastening member 38 and the compartment 1 are fastened in the direction parallel to the third axis 384, the fastening member 38 and the rotating member 36 are limited in the direction parallel to the third axis 384. Therefore, the rotating member 36 cannot rotate to the limiting position under the action of the fifth biasing member 391.

[0136] In one exemplary embodiment, the locking member 6 has a locking end 61 adapted to protrude from the tray body 1. The locking end 61 is adapted to be operated or to cooperate with the machine body so that the locking member 6 engages with the inclined surface of the rotating member 36 or the fastening member 38. This allows the locking end 61 to engage with the inclined surface of the rotating member 36 or the fastening member 38 when the user operates or when the paper tray slides into the machine body, so that the limiting part 31 rotates to the limiting position. The latter is more convenient to use. After the paper is loaded and the paper tray is reinserted into the machine body, the above action can be completed without manual operation, which is more convenient. The two ends of the seventh biasing member 7 act on the tray body 1 and the locking member 6 respectively to apply a force to the locking member 6 to move it in the direction of disengaging from the inclined surface engagement with the rotating member 36 or the fastening member 38, thereby allowing the rotating member 36 to rotate around the first axis 341 when not operated.

[0137] In one exemplary embodiment, the locking end 61 is adapted to cooperate with the machine body so that the locking member 6 cooperates with the rotating member 36 or the fastening member 38 on the inclined surface. In the direction of paper tray insertion into the machine body, the operating part 124 and the locking end 61 are arranged in sequence, so that the limiting part 31 is first located in the limiting position, then the driving part 33 is not pressed down by the lifting paperboard 2, and then the fastening member 38 is fastened to the tray body 1 under the action of the sixth biasing member 392 without disorder.

[0138] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
