Abstract

A sheet feeding apparatus includes a support portion, a guide portion, and a contact unit. The support portion rotatably supports a roll having a sheet wound to the roll. In loading the roll, the guide portion guides the roll in a guide direction from above the support portion to the support portion. The contact unit contacts an outer periphery of the roll supported by the support portion. The contact unit contacts the roll from upstream in the guide direction, and, in feeding the sheet, the sheet is fed from the roll supported by the support portion.

First claim

What is claimed is:

1 . A sheet feeding apparatus comprising:
a support portion configured to rotatably support a roll having a sheet wound to the roll; a guide portion configured to, in loading the roll, guide the roll in a guide direction from above the support portion to the support portion; and a contact unit configured to contact an outer periphery of the roll supported by the support portion, wherein the contact unit is configured to contact the roll from upstream in the guide direction, and, in feeding the sheet, the sheet is fed from the roll supported by the support portion.

2 . The sheet feeding apparatus according to claim 1 , further comprising a conveyance unit configured to convey the sheet fed from the roll in a conveyance direction,
wherein the guide portion has an opening on a conveyance unit side with respect to a vertical direction from a center of the roll supported by the support portion.

3 . The sheet feeding apparatus according to claim 1 , further comprising a cover configured to be closed to a closed position to cover the roll supported by the support portion and opened to an open position to expose the roll,
wherein the contact unit is held on the cover, and configured to bias the roll supported by the support portion using a biasing unit disposed on the cover.

4 . The sheet feeding apparatus according to claim 3 , further comprising a reading device configured to read a document,
wherein the cover and the reading device are arranged in a direction in which the sheet is fed.

5 . The sheet feeding apparatus according to claim 1 , wherein a guide path from an opening of the guide portion to the support portion is straight.

6 . The sheet feeding apparatus according to claim 1 ,
wherein the contact unit is a roller, and wherein the roller is configured to contact the outer periphery of the roll and move depending on an outer diameter of the roll.

7 . The sheet feeding apparatus according to claim 1 , further comprising:
a first gear disposed on an insertion portion to be inserted into the roll to support the roll with the support portion; a second gear disposed on the support portion and configured to be engaged with the first gear; and a motor configured to rotate the second gear.

8 . The sheet feeding apparatus according to claim 7 , wherein a first component force in the guide direction by which the contact unit presses the roll is greater than a second component force in a direction opposite to the guide direction that the insertion portion receives from driving by the motor.

9 . The sheet feeding apparatus according to claim 1 , wherein a plurality of contact units is arranged in a width direction of the roll.

10 . A recording apparatus comprising:
a support portion configured to rotatably support a roll having a sheet wound to the roll; a recording unit configured to record an image on the sheet fed from the roll supported by the support portion; a guide portion configured to, in loading the roll, guide the roll in a guide direction from above the support portion to the support portion; and a contact unit configured to contact an outer periphery of the roll supported by the support portion, wherein the contact unit is configured to contact the roll from upstream in the guide direction.

11 . The recording apparatus according to claim 10 , further comprising a conveyance unit configured to convey the sheet fed from the roll in a conveyance direction,
wherein the guide portion has an opening on a conveyance unit side with respect to a vertical direction from a center of the roll supported by the support portion.

12 . The recording apparatus according to claim 10 , further comprising a cover configured to be closed to a closed position to cover the roll supported by the support portion and opened to an open position to expose the roll,
wherein the contact unit is held on the cover, and configured to bias the roll supported by the support portion using a biasing unit disposed on the cover.

13 . The recording apparatus according to claim 12 , further comprising a reading device configured to read a document,
wherein the cover and the reading device are arranged in a direction in which the sheet is fed.

14 . The recording apparatus according to claim 10 , wherein a guide path from an opening of the guide portion to the support portion is straight.

15 . The recording apparatus according to claim 10 ,
wherein the contact unit is a roller, and wherein the roller is configured to contact the outer periphery of the roll and move depending on an outer diameter of the roll.
