Problems solved by technology

[0003] However, there are certain defects in the positioning technology of the existing paper feeding tray. The meshing between the rack and the gear is unreliable, and the rack is easy to come out of the gear, which leads to the problem of skewed paper feeding.

Embodiment 1

[0035] image 3 It is a schematic diagram of the structure of the paper supply tray provided in the first embodiment of the present invention, such as image 3 As shown, the paper supply tray includes a bottom plate 1, a regulating plate 2 and a moving device. The bottom plate 1 is used to hold paper, and there are generally two regulating plates 2, namely, the left regulating plate 2 and the right regulating plate 2, which are separately arranged on the left and right sides of the bottom plate 1 to hold the paper for positioning. The moving device includes a spiral guide rail 8. A threaded hole 10 is formed on the protrusion 9 of the regulating plate 2. The threaded hole 10 is sleeved on the spiral guide rail 8. The regulating plate 2 moves on the bottom plate 1 along the spiral guide rail 8.

[0036] In specific applications, it is not limited to use the threads of the inner wall of the threaded hole as the threads that are sleeved on the spiral guide rail to realize the threade...

Embodiment 2

[0046] Figure 4 It is a schematic diagram of the front structure of the paper supply tray provided in the second embodiment of the present invention, Figure 5 It is a schematic diagram of the rear structure of the paper supply tray provided in the second embodiment of the present invention. Such as Figure 4 , Figure 5 As shown, in this embodiment, the regulating plate 2 is separately provided on both sides of the base plate 7, and the protruding block 9 is embedded in the sliding groove 11 as the sliding block 12. Image 6 for Figure 4 Schematic diagram of the partial structure of the middle regulation board 2. The contour shape of the protrusion 9 can be set arbitrarily, such as Image 6 As shown, it can be arched. By adopting this technical solution, the spiral guide rail 8 is hidden under the bottom plate 1 of the paper supply tray, which reduces the interference of the spiral guide rail 8 on paper storage or paper feeding, and provides a more concise paper supply oper...

Abstract

The invention discloses a paper supply disc and imaging equipment. The paper supply disc comprises a base plate, a regulation plate and a moving device; the moving device comprises a spiral guide rail; the regulation plate comprises a protruded block; and a screw thread formed on the protruded block is matched with the spiral guide rail, so the regulation plate can move on the base plate along the spiral guide rail. By a mode of matching the screw thread with the screw rod, the position of the regulation plate is adjusted, so the situation that the screw thread is easy to fall off can be avoided; moreover, the stress on the screw thread is uniform, so the reliability of the movement of the regulation plate is enhanced, and the problem that the supplied paper is deflected and inclined is reduced.

Description

Technical field [0001] The embodiment of the present invention relates to the structure technology of a paper supply tray of an imaging device, and particularly relates to a paper supply tray and an imaging device. Background technique [0002] In imaging devices such as printers, copiers, fax machines, etc., paper supply trays are provided to supply paper. figure 1 Is a schematic diagram of the structure of a paper supply tray in the prior art, figure 2 for figure 1 The partial structure diagram of the middle paper tray, figure 2 It is a moving device shown at an upward angle from the bottom of the paper supply tray. The paper supply tray includes a bottom plate 100, a regulation plate 200 and a moving device. The bottom plate 100 is used to carry paper, and there are generally two regulatory plates 200, which are symmetrically arranged on both sides of the bottom plate 100, and are used to clamp and position the paper from both sides. The moving device is arranged under the ...
