Abstract

PURPOSE:To house sheets reliably in a sheet discharge stacker, by journaling an auxiliary sheet discharge lever journaled with an auxiliary sheet discharge roller rotatably to the shaft of a, sheet discharge roller thereby utilizing self- weight of the axiliary sheet discharge lever. CONSTITUTION:A printed sheet 5b passes through sheet discharge rollers 9, 10 and lifts while pushing up an auxiliary sheet discharge lever 23. The sheet 5b can be pushed up because rigidity thereof is higher than the self-weight of the auxiliary sheet discharge lever 23. When the lowermost end of the sheet 5c arrives at the sheet discharge roller 9, the lowermost end of the sheet 5c is in pressure contact with the sheet discharge roller 9 by the self-weight of the auxiliary sheet discharge lever 23, so as to house the sheet 5c in a stacker 21 through rotary force of the sheet discharge roller 9 and pressure contacting force of an auxiliary sheet discharge roller 24. Since the sheet 5c is contained in the stacker 21 with lower portion thereof pressure contacting the auxiliary sheet discharge lever 23, the sheet is contained regularly with no loosening.

In FIG. 2, when the platen shaft 12 is rotated counterclockwise in the figure by a drive source of the printer (not shown), paper is fed via the timing belt lO.
Rotate in the direction. When the paper 1-ra l rotates clockwise, the topmost sheet is separated by the left and right separating claws 7 and fed through the paper guide 20 toward the platen 11. When the top paper 5a reaches the platen 11 and is fed until an appropriate slack is formed in the paper as shown in FIG. 1, the platen 11 is rotated in the R1 direction and the top paper 5a is fed to the printing section P. The printed paper 5b passes through the paper ejection rollers 9 and 10 in FIG. When the lowermost end of the paper 5c that has further risen reaches the paper ejection roller 0, the lowermost end of the paper 5c is ejected by 1 mW of the paper ejection auxiliary lever 23 or a spring force (not shown). [Pressed against j-ra 9,
The paper 5c is accommodated in the stub force 21 by the rotational force of the paper discharge roller 0 and the pressing force of the paper discharge auxiliary roller 24. or,
Since the lower part of the stored paper 5c is pressed against the paper ejection auxiliary lever 23 as shown in FIG. 5, the paper 5c is stored in an orderly manner without any sagging.

As described above, the automatic paper feeder according to the present invention can reliably store printed paper in the stacker. In other words, the weight of the paper ejection auxiliary lever or a light spring force (not shown) ensures that the paper moves from the paper ejection roller to the paper ejection stacker. Furthermore, the printed paper has low rigidity due to the printing medium such as ink, which makes it easy for the paper to sag at the bottom, but the weight of the paper ejection auxiliary lever can suppress this sag. Therefore, the sheets that are sequentially discharged can be stored in the discharge stacker in an orderly manner.

A sheet of paper stored in a paper feed hopper installed in a printer is separated by a paper feed roller that is in pressure contact with the paper and a pair of separating claws that are in pressure contact with the left and right ends of the paper, and then fed to the printer's paper feed device. In an automatic paper feeder in which paper is loaded and the paper is stored in a stacker, a paper ejection auxiliary lever is pivotably attached to the paper ejection roller shaft into which a paper ejection roller is press-fitted to perform the paper ejection operation. The paper to be ejected moves while pushing up the paper ejection auxiliary lever, and when the paper is stored in the stacker that accommodates the ejected paper, the weight of the paper ejection auxiliary lever or a light spring is applied. An automatic paper feeder characterized in that a paper ejection auxiliary lever is pressed against the paper surface by force, and the paper moves toward the stacker.
