DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medium handling apparatus provided with a medium stacker for loading a medium discharged from the inside of the apparatus.

[0002]

2. Description of the Related Art Conventionally, a heat-fixing type electrophotographic printer as a medium handling apparatus and a facsimile apparatus as a medium handling apparatus incorporating the electrophotographic printer after printing discharged from an outlet to the outside of the apparatus. The medium or the medium after the information has been read is sequentially loaded on a medium stacker provided in an electrophotographic printer or a facsimile machine. The shape of the medium stacking surface of the medium stacker on which the medium is stacked is linear in the width (horizontal) direction of the medium, and the length (longitudinal) direction of the medium is the lowest immediately below the discharge port of an electrophotographic printer or facsimile machine. It is formed in a linear shape or an inclined shape which is formed so as to gradually increase as the distance from the outlet increases.

Since the loading surface has a slope that is the lowest immediately below the discharge port and gradually increases as the distance from the discharge port increases, the already loaded medium is pushed out by the medium discharged later. It is possible to increase the amount of loaded media without increasing the size of the apparatus even from the mounting arrangement of the internal structure of the toner cartridge, the EP unit, the fixing device, and the like.

[0004]

In the conventional media handling apparatus, there is no problem when flat media is stacked on the media stacker. However, when the media handling apparatus is an apparatus capable of printing on the medium, the printing is not performed. In some cases, a habit (curl) is generated on the medium by the operation. Since this habit occurs in the height direction of loading, the loading capacity becomes full even with a small amount of medium.For example, in a facsimile apparatus that continues to receive in an unmanned state, the medium overflows and scatters, and There has been a problem that the discharge port is closed and eventually a medium jam occurs, and the function of the apparatus stops.

It has been found that a difference (actual value) of a maximum of 60% or more occurs between the loaded amount of the medium having no habit and the medium having the habit.

[0006] Such a medium has a tendency that a large amount of water contained in the medium is excessively heated at the time of fixing the toner by heat, or the uneven distribution of water in the width direction of the medium causes uneven evaporation of water. This is caused by This is largely influenced by the fiber direction, dimensional variation, and alignment variation of cellulose (up and down in paper roll direction and paper roll direction). It is impossible to completely prevent.

In order to correct the habit, there is provided a means for applying pressure to the medium in the vicinity of the discharge port inside the apparatus, and there is a method of correcting the habit by applying pressure to the medium immediately before the paper is discharged. When used, there is a problem that a difference in effect is caused depending on the thickness of the medium, or the medium and the printing section are damaged.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a medium handling apparatus for sequentially discharging media from the inside of an apparatus to a medium stacker and stacking the medium on a medium stacking surface of the medium stacker. The medium stacker is provided rotatably with respect to the apparatus main body, and an insertion portion is formed in a part of the medium stacker. The medium stacker is provided in the apparatus main body so as to extend in the medium discharge direction. A correction rib is provided which protrudes from the insertion portion of the medium stacker in accordance with the rotating state and which protrudes to form irregularities on the medium loading surface of the medium stacker.

According to the above arrangement, by rotating the medium stacker to change the position, in the case of a medium having no habit, the medium stacking surface of the medium stacker is flattened, and the discharged medium is set in the medium stacker. Load on top. On the other hand, in the case of a medium having a habit, the correction rib protrudes from the medium stacker to form irregularities on the medium stacking surface, so that even if the medium has a habit, the apparent appearance when the medium is stacked on the medium stacker is displayed. Even if the height is reduced and the medium has a habit, a small amount of medium does not block the discharge port.

5 is such that the boss 58 is fitted into the center fixing hole 57b, and the heights of the document receiving ribs 53a and 53b and the correction rib 55 are the same, so that the document receiving rib 53a, the document receiving rib 53b, and the document rib The original 31
Are supported at three points at both ends and the center of the document 31 in the width direction. And the media loading surface becomes flat by this,
It is possible to stack originals 31 equivalent to a flat surface.

Next, the habitual original 31 is transferred to the original stacker 41.
The operation of loading on top will be described.

When the habit is upward, as shown in FIG. 33, the original stacker 41 is fixed at the lowermost position, and the correction rib 55 is fitted with the boss 58 in the lower fixing hole 57c, and the original receiving rib 53a is formed. , 53b are higher than the correction ribs 55b, and are fixed in a state where irregularities are formed on the medium loading surface. This allows
With the same effect as in the first embodiment, the habit portions at both ends in the width direction of the original 31 sink due to gravity, and the original 31
And the apparent height of the original 31 is reduced, and a stacking amount close to the original 31 without habit can be secured.

When the habit is downward, the original stacker 41 is fixed at the lowermost position as shown in FIG.
Reference numeral 5 denotes a state in which the boss 58 is fitted into the upper fixing hole 57a, the height of the correction rib 55 is made lower than that of the document receiving ribs 53a, 53b, and the unevenness is formed on the medium loading surface. Thus, when the original receiving ribs 53a and 53b receive the habit portions at both ends in the width direction of the original 31, the correction rib 55 corresponding to the center of the original 31 is lowered. , And the apparent height of the document 31 decreases. As a result, similar to the case where the habit is upward, a stacking amount close to the document 31 having no habit can be secured.

In the case of the original 31 having a large habit, there is a low possibility that the habit of the original 31 will be corrected by sinking due to gravity. There is a possibility that the discharge port 35 may be blocked even if the stack is loaded. In such a case, FIG.
As shown in FIG. 6, the original stacker 41 is fixed to the uppermost part, and the position of the correction rib 55 is fixed according to the condition of the upper curl or the lower curl, so that the position of the rear end of the recording paper 31 sinks and is discharged. It will not disturb the paper. This allows
Even if the habit is large, a stacking amount close to the original 31 without habit can be secured.

As described above, in the third embodiment, both the original stacker 41 and the correction rib 55 are rotatable, so that the same effects as those of the first embodiment can be obtained, and the original having a large habit can be obtained. Even in the case of 31, it is possible to secure a stacking amount close to the original 31 without habit.

The document stacker 41 may be a non-rotating stacker.
