Abstract

A medium stacking device includes side guides that are respectively disposed in a width direction parallel to a sheet face of the medium and orthogonal to a direction of progress at positions on both sides of a portion of a stage on which a medium is stacked, and that respectively guide the medium discharged from a discharge section in the width direction using a stacking guide face. Each side guide includes a discharge guide face that guides toward a central side in the width direction on progression from the discharge section along the direction of progress, a support guide face that supports the medium from a side of the stage, and a guiding valley portion that is an adjoining portion between the discharge guide face and the support guide face, that causes a vertex or edge of the medium to slide with progression of the medium, and that causes a leading edge portion of the medium in the direction of progress to pass further to a stacking direction side than the stage arm.

First claim

The invention claimed is:

1. A medium stacking device, comprising:
a discharge section that discharges a paper sheet shaped medium into a stacking space and moves the medium in a direction of progress;
a stage that includes a placement face on which the medium is placed in the stacking space, and that stacks the medium in a stacking direction that is a direction leading away from the placement face;
side guides that are respectively disposed in a width direction, which is parallel to a sheet face of the medium and orthogonal to the direction of progress, at positions on both sides of a portion of the stage on which the medium is stacked, and that respectively guide the medium discharged from the discharge section in the width direction using a stacking guide face;
a stage moving section that moves the stage along the stacking direction such that a spacing in the stacking direction between the discharge section and the placement face of the stage is a stacking spacing appropriate for stacking the medium or larger; and
a stage arm that is provided on an opposite side of the side guides to the discharge section, and that links the stage and the stage moving section together, wherein
each of the side guides includes:
a discharge guide face that guides toward a central side in the width direction on progression from the discharge section along the direction of progress,
a support guide face that supports the medium from a side of the stage, and
a guiding valley portion that is an adjoining portion between the discharge guide face and the support guide face, that causes a vertex or edge of the medium to slide with progression of the medium, and that causes a leading edge portion of the medium in the direction of progress to pass further to a stacking direction side than the stage arm, and
a guiding inclined face which is an inclined face that guides the medium toward the side of the stage, the guiding inclined face being formed between the support guide face of the guiding valley portion and the stacking guide face.

2. The medium stacking device of claim 1 , wherein
the guiding valley portion has a valley portion progress side end point, which is an end point of the guiding valley portion on a side of the direction of progress of the medium, and the discharge section has a discharge point where the medium is discharged, and
the valley portion progress side end point is set such that a first imaginary extension line passing through the discharge point and the valley portion progress side end point passes through the stacking direction side of the stage arm.

3. The medium stacking device of claim 1 , wherein
the guiding valley portion has a valley portion progress side end point which is an end point of the guiding valley portion on a side of the direction of progress of the medium and is set such that an imaginary extension line, which imaginarily extends the guiding valley portion along the direction of progress of the medium, passes through the stacking-direction side of the stage arm.

4. The medium stacking device of claim 1 , wherein, in the side guide, at least a portion of the support guide face is formed further to a central side in the width direction than the discharge guide face.

5. The medium stacking device of claim 1 , wherein, in the side guide, at least a portion of the support guide face is formed further to an outer side in the width direction than the discharge guide face.

6. The medium stacking device of claim 1 , wherein, in the side guide, the support guide face and the guiding inclined face are adjacent to each other.

7. The medium stacking device of claim 1 , wherein, in the side guide, a second discharge guide face is formed between the support guide face and the guiding inclined face.

8. The medium stacking device of claim 7 , wherein the second discharge guide face is substantially parallel to the discharge guide face.

9. The medium stacking device of claim 1 , wherein the discharge guide face and the support guide face are joined together by a continuous curving face at the guiding valley portion of the side guide.
