Description

Technical Field

[0001] The present invention relates to the technical field of printing devices, and particularly to a paper storage mechanism and a printing device using the paper storage mechanism. Background Art

[0002] The paper tray of a printer is used to place unprinted paper. A regulating plate is provided in the paper tray to restrict the width direction of the paper, so as to ensure that the paper will not tilt when being conveyed, thereby avoiding paper feeding failure and paper jamming. Generally, the regulating plate consists of two parts and is linked through a gear-rack combination. When the user operates one regulating plate to move, the other regulating plate moves synchronously. The user operates the regulating plate to move to adapt to different sizes of paper and can maintain the clamping of the paper in the width direction. However, the width differences of some paper types are very close. For example, for A4 and LTR paper types, when the user adjusts the position of the regulating plate, the position may not be aligned correctly, and the regulating plate may be adjusted to a position that does not match the paper type, either too large or too small, resulting in the position of the paper not being well restricted. Therefore, the paper may tilt when entering the printer, and then paper jamming may occur.

[0003] In the prior art, a part is provided between the regulating plate and the paper tray housing. The length, width, and height of this part are specifically designed to match the size of the paper. When a certain paper type is placed in the paper tray, the user installs the part on the paper tray housing or the regulating plate in the corresponding dimension direction. However, this will add an extra part, increase the cost, and the part is too small and easy to lose, causing inconvenience to the user. Summary of the Invention

[0004] In order to solve the above problems, the present utility model provides a paper tray to prevent the user from adjusting the regulating plate to the wrong position and facilitate the user's operation.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] AsFigure 1 , 2 A paper storage mechanism 5 as shown includes a housing 1 and a regulating plate 2 movably mounted on the housing 1. A position limiting member 3 is integrally formed on one of the housing 1 and the regulating plate 2. As the regulating plate 2 moves, the position limiting member 3 abuts against the housing 1 or the regulating plate 2. The position limiting member 3 can be in a regular or irregular shape, preferably a regular shape, such as a cube or a cuboid, and its length, width and height are respectively set to correspond to the size of the paper. When the regulating plate 2 moves to a position consistent with the paper type, the position limiting member 3 just abuts against the housing 1 or the regulating plate 2 and cannot move further, which can prevent the user from adjusting the regulating plate 2 to the wrong position. When the user needs a larger size of paper, the position limiting member 3 can be cut off or broken off, and the regulating plate 2 can move to a farther position.

[0023] Generally, the paper type used by the user is relatively fixed, and the papers in a paper storage mechanism 5 will not be frequently replaced with different sizes. Therefore, removing the position limiting member 3 will not cause inconvenience to the user. When some users have a particularly large printing volume and a variety of paper types, they will choose a printing device 4 with multiple paper storage mechanisms 5. For the convenience of user identification, a paper type identifier 31 can be set on the surface of the position limiting member 3, such as A3, A4, LTR, etc. The paper type identifier 31 can be silk-screened or formed by a mold.

[0024] To facilitate the user to remove the position limiting member 3, at least one connecting structure 32 is provided on the position limiting member 3 to connect with the housing 1 or the regulating plate 2. The width of the connecting structure 32 is smaller than the width of the position limiting member 3, which is convenient for the user to cut off or break off. For the convenience of user operation, the position limiting member 3 can be set at a position close to the edge along the direction in which the paper is conveyed on the regulating plate 2. Specifically, the position limiting member 3 is set at the edge position on the side of the regulating plate 2 away from the center of the paper.

[0025] In another design, the position limiting member 3 can also be made of an elastic material, so that the position limiting member 3 can be bent and will not limit the further movement of the regulating plate 2. The user does not need to cut off or break off the position limiting member 3, which improves the operation convenience to a certain extent. Further, the connecting structure 32 can also be made of an elastic material.

[0026] The paper storage mechanism 5 of the present utility model can be provided with one, two or three regulating plates according to the user's needs. This is prior art and will not be elaborated here. The present utility model takes three regulating plates as an example. As shown in the appendix Figure 1As shown, the housing 1 is provided with a first regulating plate 21 and a second regulating plate 22, which respectively contact with two opposite sides of the paper. The first regulating plate 21 and the second regulating plate 22 can realize relative movement through the cooperation of the gear and the rack. This is the prior art and will not be described in detail. The position limiting component 3 can be set on one of the regulating plates or on both regulating plates at the same time to achieve balanced force on the regulating plates. It also allows users to see that there are position limiting components 3 on both regulating plates, and they will not think that one of the regulating plates without the position limiting component 3 has not moved into place, and then force is applied to it. The position of the third regulating plate 23 is perpendicular to the positions of the first regulating plate 21 and the second regulating plate 22 on the horizontal plane, and is used to contact with the third side of the paper. When the first regulating plate 21 and the second regulating plate 22 limit the width direction position of the paper, the third regulating plate 23 can limit the tail end of the paper in the paper feeding direction. A position limiting component 3 is provided on the third regulating plate 23 . When the third regulating plate 23 moves to the rear side wall of the housing 1 , the position limiting component 3 will come into contact with the housing 1 , thereby limiting the movement of the third regulating plate 23 .

[0027] like Figure 3 As shown in the structural diagram, when the position limiting component 3 is arranged on the housing 1 , a connecting structure 32 can also be provided to connect the position limiting component 3 and the regulating plate 2 .

[0028] like Figure 4 In the printing device 4 shown, the paper storage mechanism 5 can be detachably removed from or inserted into the printing device 4. When the user needs to put paper into the paper storage mechanism 5, the paper storage mechanism 5 can be pulled out of the printing device 4. The user moves the regulation plate 2 to the corresponding position according to the size of the paper. The regulation plate 2 adopts the structure of the utility model, and the user can determine whether to remove the position limiting component 3 according to the paper type. When the paper storage mechanism 5 is inserted into the printing device 4, it can prevent the paper from being stuck with dust. However, there are also some small printing devices that are small in size and do not have a paper storage mechanism 5. A fixed paper storage mechanism is used, but a regulation plate is still provided. A position limiting component can also be provided on the regulation plate to conflict with the printer body or the paper lifting plate.

[0029] Although the implementation methods disclosed in the utility model are as above, the above contents are only implementation methods adopted to facilitate understanding of the technical solution of the utility model, and are not used to limit the utility model. Any technician in the field to which the utility model belongs can make any modifications and changes in the form and details of implementation without departing from the spirit and scope disclosed in the utility model, but the scope of patent protection of the utility model shall still be based on the scope defined in the attached claims.
