Paper transporting structure

Abstract

A paper transporting structure defines a paper transport channel and includes a sliding piece, a fixing holder, a rotating arm, and an elastic member. When the sliding piece slides to a first position of the fixing holder, the sliding piece is fixed at the first position and abuts the rotating arm to hold the rotating arm positioned at a first paper transporting angle. When the sliding piece slides to a second position of the fixing holder, the elastic member rebounds and drives the rotating arm to rotate to a second paper transporting angle.

Description

FIELD

The subject matter herein generally relates to paper transporting structures.

BACKGROUND

Printers include a paper transporting structure and a printing body. The paper transporting structure defines a paper transport channel. Paper passes through the paper transport channel to enter into a paper inlet of the printing body. A position of an outlet of the paper transport channel is typically fixed. The paper inlet of various printing bodies can be different. Thus, one paper transporting structure only matches one type of printing body.

FIG. 1 to FIG. 5 illustrate a paper transporting structure 100 including a paper transporting gate 20, a paper guide 30, a rotating arm 40, a paper transferring assembly 50, a fixing holder 60, a sliding piece 70, and an elastic member 80. The paper guide 30 is fixed above the paper transporting gate 20. The paper transporting gate is part of a pivotable door attached to the rest of the printer (not shown) A paper transport channel 22 is defined between the paper transporting gate 20 and the paper guide 30. The rotating arm 40 is rotatably attached to the paper transporting gate 20 and positioned at an outlet 24 of the paper transport channel 22. The fixing holder 60 is attached to the paper guide 30 and positioned at the outlet 24. The sliding piece 70 is slidably attached to the fixing holder 60. The elastic member 80 is attached to the paper transporting gate 20 and abuts the rotating arm 40.

When an external force is exerted on the sliding piece 70 to drive the sliding piece 70 to slide to a first position of the fixing holder 60, the sliding piece 70 is fixed at the first position and abuts the rotating arm 40 to hold the rotating arm 40 positioned at a first paper transporting angle 26. The paper transferring assembly 50 transfers a paper in the paper transport channel 22 to the rotating arm 40 and drives the paper to leave the rotating arm 40 in the first paper transporting angle 26. When an external force is exerted on the sliding piece 70 to drive the sliding piece 70 to slide to a second position of the fixing holder 60, the elastic member 80 rebounds and drives the rotating arm 40 to rotate to a second paper transporting angle 28. The paper transferring assembly 50 transfers a paper in the paper transport channel 22 to the rotating arm 40 and drives the paper to leave the rotating arm 40 in the second paper transporting angle 28.

The paper transferring assembly 50 includes at least one drive wheel 52 and at least one driven wheel 54. A motor for driving driven wheel 54 is not shown. The drive wheel 52 is attached to the paper transporting gate 20 and is adjacent to the rotating arm 40. The driven wheel 54 is opposite to the drive wheel 52. A paper transferring gap 56 is defined between the driven wheel 54 and the drive wheel 52. The paper transferring assembly 50 transfers the paper to the paper transferring gap 56 and the paper passes through the paper transferring gap 56 to be transferred to the rotating arm 40. In the exemplary embodiment, the paper transferring assembly 50 includes two drive wheels 52 and two driven wheels 54.

The fixing holder 60 includes an elastic protruding hook 62 opposite to the sliding piece 70. The sliding piece 70 defines a sliding groove 72. The sliding groove 72 includes a sliding area 74, a first locking groove 76, and a second locking groove 78. The sliding area 74 is positioned between the first locking groove 76 and the second locking groove 78. In the embodiment, the first locking groove 76 and the second locking groove 78 are positioned at two ends of the sliding area 74. When the sliding piece 70 slides to lock the elastic protruding hook 62 in the first locking groove 76, the sliding piece 70 abuts the rotating arm 40 to hold the rotating arm 40 positioned at the first paper transporting angle 26. When the elastic protruding hook 62 slides along the sliding area 74 to be locked in the second locking groove 78, the elastic member 80 rebounds and drives the rotating arm 40 to rotate to the second paper transporting angle 28.

The fixing holder 60 further includes at least one guiding portion 64 opposite to the sliding piece 70. The sliding piece 70 further defines at least one guiding groove 75. The guiding portion 64 is slidably received in the guiding groove 75 to guide the sliding piece to slide. In the embodiment, the fixing holder 60 includes two guiding portions 64. The sliding piece 70 defines two guiding grooves 75.

The paper transporting gate 20 defines a cylindrical receiving hole 21. The elastic member 80 is received in the receiving hole 21 and abuts the rotating arm 40. The elastic member 80 can be a spiral spring. The paper transporting gate 20 further defines two opposite accommodating holes 23. Two rotating portions 42 protrude from each of the two ends of the rotating arm 40. The two rotating portions 42 are rotatably received in the two accommodating holes 23. An axis of the receiving hole 21 is perpendicular to an axis of the accommodating hole 23.

The exemplary embodiments shown and described above are only examples. Even though numerous descriptions and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
