Abstract

Claims (56)

1 . A sheet feeding device comprising:

a holder portion that rotatably supports a roll sheet around which a sheet is wound;

a first guide portion projecting from the holder portion in a projection direction corresponding to a front direction of the sheet feeding device to guide the roll sheet to the holder portion;

a second guide portion facing the first guide portion and projecting from the holder portion in the projection direction to guide the roll sheet to the holder portion;

an arm member configured to guide the sheet fed from the roll sheet supported by the holder portion; and

a contact member configured to come into contact, from below with respect to a gravity direction, with an outer peripheral surface of the roll sheet supported by the holder portion and configured to be moved by the arm member according to an outer diameter of the roll sheet,

wherein, in a gap between the first guide portion and the second guide portion and below the gap, a space that can be entered by a carrier that carries the roll sheet is formed, and

wherein the space is formed on a tip end side in the projection direction with respect to the contact member.

2 . The sheet feeding device according to claim 1 ,

wherein the first guide portion and the second guide portion support the roll sheet via an attachment member that is attached to the roll sheet so as to project from both end portions of the roll sheet in a width direction thereof.

3 . The sheet feeding device according to claim 2 ,

wherein the first guide portion has a first guide surface on which the attachment member is to be placed, and

wherein the second guide portion has a second guide surface formed in the same plane as that of the first guide surface.

4 . The sheet feeding device according to claim 3 ,

wherein the holder portion has a first bearing surface and a second bearing surface each rotatably supporting the attachment member, a first connecting surface connecting the first bearing surface and the first guide surface, and a second connecting surface connecting the second bearing surface and the second guide surface.

5 . The sheet feeding device according to claim 3 ,

wherein a step portion projecting upward from the first guide surface is provided at a tip end of the first guide portion in the projection direction, and

wherein a step portion projecting upward from the second guide surface is provided at a tip end of the second guide portion in the projection direction.

6 . The sheet feeding device according to claim 2 , further comprising:

a first regulating portion that comes into contact, in a facing direction in which the first guide portion and the second guide portion face each other, with the attachment member in a first direction to regulate movement of the attachment member in a second direction opposite to the first direction; and

a second regulating portion that comes into contact with the attachment member in the second direction to regulate movement of the attachment member in the first direction.

7 . The sheet feeding device according to claim 6 ,

wherein the first regulating portion and the second regulating portion are formed in the first guide portion.

8 . The sheet feeding device according to claim 7 , further comprising:

a third regulating portion that comes into contact with the attachment member in the first direction to regulate movement of the attachment member in the second direction, the third regulating portion being formed in the second guide portion.

9 . The sheet feeding device according to claim 2 , further comprising:

a drive gear configured to be connected to the attachment member.

10 . The sheet feeding device according to claim 1 ,

wherein the first guide portion has a first rear member projecting from the holder portion in the projection direction and a first front member projecting from the first rear member in the projection direction,

wherein the second guide portion has a second rear member projecting from the holder portion in the projection direction and a second front member projecting from the second rear member in the projection direction, and

wherein the space is formed at least in a gap between the first front member and the second front member and below the gap between the first front member and the second front member.

11 . The sheet feeding device according to claim 10 ,

wherein the first front member is configured to be movable to a position where the first front member is contained inside the first rear member, and

wherein the second front member is configured to be movable to a position where the second front member is contained inside the second rear member.

12 . The sheet feeding device according to claim 1 , further comprising:

a flapper arranged above the arm member and configured to come into contact with the outer peripheral surface of the roll sheet.

13 . A recording apparatus comprising:

a sheet feeding device; and

a recording portion that performs a recording operation on a sheet fed out from the sheet feeding device,

wherein the sheet feeding device includes:

a holder portion that rotatably supports a roll sheet around which a sheet is wound;

a first guide portion projecting from the holder portion in a projection direction corresponding to a front direction of the sheet feeding device to guide the roll sheet to the holder portion;

a second guide portion facing the first guide portion and projecting from the holder portion in the projection direction to guide the roll sheet to the holder portion;

an arm member configured to guide the sheet fed from the roll sheet supported by the holder portion; and

a contact member configured to come into contact, from below with respect to a gravity direction, with an outer peripheral surface of the roll sheet supported by the holder portion and configured to be moved by the arm member according to an outer diameter of the roll sheet,

wherein, in a gap between the first guide portion and the second guide portion and below the gap, a space that can be entered by a carrier that carries the roll sheet is formed, and

wherein the space is formed on a tip end side in the projection direction with respect to the contact member.

14 . The recording apparatus according to claim 13 , further comprising:

a winding portion located, in the projection direction, on the same side as that of the holder portion with respect to the recording portion, the winding portion supporting a roll that takes up the sheet on which the recording operation has been performed.

15 . The recording apparatus according to claim 14 ,

wherein the winding portion is located below the holder portion,

wherein the recording apparatus further comprises a sheet guide member that guides the sheet from the recording portion to the winding portion, and

wherein the sheet guide member is movable between a first position where the sheet guide member covers the holder portion from a tip end side of the first guide portion in the projection direction and guides the sheet to the winding portion, and a second position where the holder portion is relieved and does not interfere with the roll sheet in a case the carrier supporting the roll sheet entering the space.

16 . The recording apparatus according to claim 15 ,

wherein the first guide portion and the second guide portion are deformable into a first state where a length of projection of each of the first guide portion and the second guide portion from the holder portion is a first length and a second state where the length of projection is a second length longer than the first length, and

wherein the recording apparatus further comprises a drive connection mechanism that deforms a state of the guide portion from the first state to the second state in conjunction with movement of the sheet guide member from the first position to the second position.
