Abstract

A feeder includes a pressing section that presses a medium after a feeding force is applied on the medium in a direction in which a leading edge of the medium set in a setting section in a feeding direction abuts on an abutment section during feeding of the media by a feed roller.

First claim

What is claimed is:

1. A feeder comprising:
a setting section in which a plurality of media is set in a stacked state;
a feed roller that feeds the medium set in the setting section in a feeding direction;
an abutment section on which a leading edge of the medium set in the setting section in a feeding direction abuts;
a support section that supports the medium set in the setting section and moves to allow the medium to be in contact with the feed roller during feeding of the media by the feed roller; and
a pressing section that is configured to press the medium set in the setting section against the feed roller to apply a force in a stacking direction of the medium,
wherein the pressing section is configured to press the medium after a feeding force is applied on the medium in a direction that allows the leading edge to abut on the abutment section during feeding of the media by the feed roller, and
wherein a movement speed of the support section is faster before the medium comes into contact with the feed roller than after the medium comes into contact with the feed roller during feeding of the media by the feed roller.

2. The feeder according to claim 1 , wherein a first driving source that rotates the feed roller and a second driving source that moves the support section are different.

3. The feeder according to claim 2 , further comprising a transportation roller that transports the medium which is fed by the feed roller, wherein the second driving source also rotates the transportation roller.

4. The feeder according to claim 1 , wherein the feed roller is driven before the support section moves during feeding of the media by the feed roller.

5. The feeder according to claim 1 , wherein the abutment section is a separating roller that cooperates with the feed roller to hold and separate the medium set in the setting section.

6. The feeder according to claim 5 , further comprising a flap that is switched between a state engaged with the support section and disengaged from the support section and configured to allow the pressing section to press the medium against the feed roller in the disengaged state, the flap assuming the disengaged state and being pressed by the medium during feeding of the media by the feed roller so as to be set back downstream in the feeding direction, wherein
a rotation speed of the feed roller is faster when the flap is in the state disengaged from the support section than when the flap is in the state engaged with the support section.

7. The feeder according to claim 1 , wherein the abutment section is a flap that is switched between a state engaged with the support section and disengaged from the support section and configured to allow the pressing section to press the feed roller in the disengaged state, the flap assuming the disengaged state and being pressed by the medium during feeding of the media by the feed roller so as to be set back downstream in the feeding direction.

8. An image reading apparatus comprising:
a reading unit that reads an image formed on the medium; and
the feeder according to claim 1 that feeds the medium to the reading unit.

9. A recording apparatus comprising:
a recording unit that performs recording on the medium; and
the feeder according to claim 1 that feeds the medium to the recording unit.
