Description

Technical Field

[0001] The invention relates to a tray and a printer using the tray. Background Art

[0002] At present, in the field of ticket printing, ticket paper is different from ordinary paper. Because it has chain holes on both sides, there are burrs around the chain holes, and the thickness increases, as the paper is stacked, it will show a trend of high sides and low middle, that is, the paper bends upward in the longitudinal direction, such as Figure 1 When paper is ejected, because the paper bends upward, the chain hole is at the top. During the paper ejection process, the corner of the next paper may get stuck in the chain hole, and the paper cannot be ejected normally. Figure 2 shown.

[0003] In order to solve this problem, the existing solution is to add a bulge on the top of the tray (the bulge can be added horizontally or vertically), so that the first sheet of paper will have a certain deformation at the beginning, ensuring that the top sheet of paper is flat or droops on both sides, forming a trend of high in the middle and low on both sides, such as Figure 3 Although this solution can solve the above problems, it also causes the problem of uneven paper delivery. Since the paper is in a raised state at the beginning, when the next paper is delivered, the paper will slide to the two ends of the raised state, resulting in uneven paper delivery. Figure 5 shown. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a tray which can not only enable smooth paper discharge and paper removal, but also facilitate neat paper discharge.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a tray, which is used to place paper, and comprises:

[0006] When a paper is placed on it, the elastic deformation sheet can generate a corresponding elastic deformation amount according to the state of the paper stacking, and the upper surface of the elastic deformation sheet is used to place the paper;

[0007] A support assembly is used to contact the lower surface of the elastic deformation piece, and the support assembly is used to support at least the middle position of the elastic deformation piece.

[0008] A specific structure of a support assembly is further provided, wherein the support assembly comprises a support column, the upper end of which supports the middle portion of the elastic deformation sheet.

[0009] Another specific structure of a support assembly is further provided. The support assembly includes two support columns, and the two support columns are arranged along a paper placing direction or a paper discharging direction.

[0010] Another specific structure of a support assembly is further provided. The support assembly includes two support columns, and the two support columns are arranged in a direction perpendicular to a paper placing direction or a paper discharging direction.

[0011] Another specific structure of a support assembly is further provided. The support assembly includes three support columns, and the three support columns are arranged in a direction perpendicular to a paper placing direction or a paper discharging direction.

[0012] Furthermore, the support column is a cylindrical structure.

[0013] The invention also provides a printer, which comprises the tray.

[0014] After adopting the above technical scheme, the present invention adopts an elastic elastic deformation sheet as a tray for placing paper. The elastic deformation sheet is supported by a supporting device in the middle of at least the lower surface thereof (the supporting method can be various). Since the elastic deformation sheet has good elastic deformation, it can produce corresponding deformation according to the deformation of the paper (stacked state). The so-called elastic deformation refers to the deformation of an object by external force, but after the external force is removed, it will still restore its original shape. This tray uses this characteristic to solve the arc compensation of narrow bill paper in a targeted manner. As more and more paper is piled on the elastic deformation sheet, the elastic deformation sheet will be bent by the paper. Since the elastic deformation sheet is supported by a supporting column in the middle, the elastic deformation sheet will show a downward trend on both sides, making the most The paper on top is always in a flat state, so when paper is discharged, the corner of the next paper will not be stuck in the chain hole, and smooth paper discharge can be achieved; in addition, the material, shape and thickness of the elastic deformation sheet can be unfixed, and the area of ​​the support column supporting the elastic deformation sheet is also unfixed, which needs to be determined according to different papers, paper thickness, and paper size. The elastic deformation degree of elastic deformation sheets of different materials is also different. Compared with other paper discharge methods, the tray of the present invention can not only make paper discharge and paper removal smooth, solve the problem of paper jam during paper discharge, but also solve the problem of uneven paper discharge. It not only has a simple structure, but also saves space and cost. It does not require complicated programs and sensors to control, and mainly relies on the natural deformation of the elastic deformation sheet to compensate for the arc bending of the paper.

[0032] A supporting assembly, wherein the supporting assembly is used to contact the lower surface of the elastic deformation piece 1 , and the supporting assembly is used to support at least the middle position of the elastic deformation piece 1 .

[0033] The support assembly includes a support column 2 , the upper end of which supports the middle part of the elastic deformation sheet 1 .

[0037] Embodiment 3

[0038] The structure of the tray in this embodiment is basically the same as that in the first embodiment, except that: Fig.10 As shown, the support assembly includes two support columns 2, and the two support columns 2 are arranged in a direction perpendicular to the paper discharge direction of the paper; in this embodiment, the vertical direction of the paper discharge direction is the connection line direction of the chain holes correspondingly aligned at the two ends.

[0039] Embodiment 4

[0040] The structure of the tray of this embodiment is basically the same as that of the first embodiment, except that: Fig.11 As shown, the support assembly includes three support columns 2, and the three support columns 2 are arranged along the vertical direction of the paper discharge direction; in this embodiment, the vertical direction of the paper discharge direction is the connection line direction of the chain holes correspondingly aligned at the two ends.

[0041] Embodiment 5

[0042] like Figures 12-13 As shown, a printer includes a tray according to any one of the first to fourth embodiments, such as Fig.12 The structure of the printer using the tray in the first embodiment is not limited thereto; specifically, the printer 10 is provided with a paper channel having a paper inlet 101 and a paper outlet 102 , and the paper coming out of the paper outlet 102 is placed on the elastic deformation sheet 1 .

[0043] The material, shape and thickness of the elastic deformation sheet used in the above embodiments may not be fixed, and the area of ​​the support column supporting the elastic deformation sheet is also not fixed, and it needs to be determined according to different papers, paper thickness, and paper size. The elastic deformation degree of elastic deformation sheets made of different materials is also different; the number of support rods is also uncertain and should be selected according to specific circumstances.

[0044] The working principle of the present invention is as follows:

[0045] The present invention adopts an elastic elastic deformation sheet 1 as a tray for placing paper. The elastic deformation sheet 1 is supported by a supporting device at least in the middle of the lower surface thereof (the supporting method can be various). Since the elastic deformation sheet has good elastic deformation, it can produce corresponding deformation according to the deformation of the stacked paper. The so-called elastic deformation refers to the deformation of an object caused by external force, but after the external force is removed, it will still restore its original shape. The tray uses this characteristic to solve the arc compensation of the narrow bill paper in a targeted manner. As more and more paper is piled on the elastic deformation sheet, the elastic deformation sheet will be bent by the paper. Since the elastic deformation sheet 1 is supported by the support column 2 in the middle, the elastic deformation sheet 1 will tend to move downward on both sides, so that the top paper is always in a flat state. In this way, when paper is discharged, the corner of the next paper will not be stuck in the chain hole, and smooth paper discharge can be achieved. Compared with other paper discharge methods, the tray of the present invention can not only make paper discharge and paper removal smooth, solve the problem of paper discharge jam, but also solve the problem of uneven paper discharge. It not only has a simple structure, but also saves space and cost. It does not require complicated programs and sensors to control, and mainly relies on the natural deformation of the elastic deformation sheet 1 to compensate for the arc bending of the paper.

It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
