Abstract

A recording apparatus includes a containing portion that contains a rolled sheet obtained by winding a sheet and a recording portion that records an image on the sheet fed from the rolled sheet contained in the containing portion and further includes an opening/closing member that can be movable between an open position at which the containing portion is opened and a closed position at which the containing portion is closed and a first guiding portion provided in the opening/closing member to guide the rolled sheet to the containing portion in a case where the opening/closing member is at the open position.

First claim

What is claimed is:

1. A recording apparatus comprising:
a containing portion that contains a rolled sheet obtained by winding a sheet;
a recording portion that records an image on the sheet fed from the rolled sheet contained in the containing portion;
a cover member movable between an open position at which the rolled sheet can be placed on the cover member before being placed in the containing portion and a closed position at which the containing portion is covered;
a first guiding portion provided in the cover member to guide the rolled sheet to the containing portion in a case where the cover member is at the open position; and
a discharge portion provided above the cover member to discharge the sheet on which the image is recorded by the recording portion,
wherein in a case where the cover member is at the closed position, an upper side of the cover member forms a portion of a discharge port of the discharge portion.

2. The recording apparatus according to claim 1 , wherein the discharge portion, is provided above the containing portion, and
wherein, at the closed position, the cover member restricts entrance of the sheet discharged from the discharge portion.

3. The recording apparatus according to claim 1 , further comprising a second guiding portion that guides the rolled sheet guided by the first guiding portion to allow the rolled sheet to be contained in the containing portion.

4. The recording apparatus according to claim 3 ,
wherein the first guiding portion and the second guiding portion are configured such that the guiding of the rolled sheet by the second guiding portion is continued from the guiding of the rolled sheet by the first guiding portion.

5. The recording apparatus according to claim 3 , further comprising an auxiliary member to be integrally attached to the rolled sheet to assist holding of the rolled sheet in the containing portion, the auxiliary member having a shaft portion to be pivotally supported in the containing portion,
wherein the second guiding portion guides the shaft portion to thereby guide the rolled sheet to the containing portion.

6. The recording apparatus according to claim 5 ,
wherein the auxiliary member has flange portions to be attached to the shaft portion so as to widthwise come into contact with widthwise both ends of the rolled sheet, and
wherein the first guiding portion has a flange guiding portion that guides the flange portions.

7. The recording apparatus according to claim 6 ,
wherein a guiding surface of the flange guiding portion that guides the flange portions and a guiding surface of the second guiding portion that guides the shaft portion overlap each other in a direction in which the rolled sheet is guided.

8. The recording apparatus according to claim 5 ,
wherein the first guiding portion has a shaft portion guiding portion that guides the shaft portion.

9. The recording apparatus according to claim 8 ,
wherein a guiding surface of the shaft portion guiding portion that guides the shaft portion and a guiding surface of the second guiding portion that guides the shaft portion overlap each other in a direction in which the rolled sheet is guided.

10. The recording apparatus according to claim 5 ,
wherein the first guiding portion has a rolled sheet guiding portion that guides an outer peripheral surface of the rolled sheet.

11. The recording apparatus according to claim 10 ,
wherein a guiding surface of the rolled sheet guiding portion that guides the shaft portion and a guiding surface of the second guiding portion that guides the shaft portion overlap each other in a direction in which the rolled sheet is guided.

12. The recording apparatus according to claim 5 ,
wherein the cover member has a temporary placement portion on which, at the open position, the rolled sheet can temporarily be placed before being guided by the first guiding portion.

13. The recording apparatus according to claim 12 ,
wherein the auxiliary member includes the shaft portion to be inserted into a hollowed space portion of the rolled sheet and a pair of flange portions to be attached to the shaft portion so as to widthwise come into contact with widthwise both ends of the rolled sheet, and
wherein the temporary placement portion has an abutment surface against which one of the pair of flange portions is allowed to widthwise abut in a case where the auxiliary member is attached to the rolled sheet.

14. The recording apparatus according to claim 13 ,
wherein the second guiding portion has a flange guiding surface that widthwise comes into contact with one of the pair of flange portions to guide the flange portion, and
wherein the abutment surface and the flange guiding surface are at substantially same widthwise positions to form a guiding surface which is indiscrete in a direction in which the rolled sheet is guided.

15. The recording apparatus according to claim 1 ,
wherein the cover member has an inner surface provided with the first guiding portion and an outer surface that guides, at the closed position, the sheet discharged from the discharge port.

16. The recording apparatus according to claim 15 ,
wherein the open position is a position at which the cover member is in a posture horizontally protruding from an apparatus side surface provided with the discharge port of the discharge portion and the inner surface is upwardly open, and
wherein the closed position is a position at which the cover member is in a posture to be along the apparatus side surface and the inner surface is horizontally opposed to the rolled sheet in the containing portion.

17. The recording apparatus according to claim 1 , further comprising:
a first containing portion provided below a discharge portion that discharges the sheet on which the image is recorded by the recording portion and a second containing portion provided below the first containing portion, the first containing portion and the second containing portion serving as the containing portion;
a first cover member provided correspondingly to the first containing portion and a second cover member provided below the first cover member correspondingly to the second containing portion, the first cover member and the second cover member serving as the cover member; and
a restricting portion that restricts the sheet discharged from the discharge portion from advancing in a gap between the first cover member and the second cover member.

18. The recording apparatus according to claim 17 ,
wherein the restricting portion forms a wall partially closing the gap in a widthwise direction of the rolled sheet.

19. The recording apparatus according to claim 18 ,
wherein the wall is provided in plurality and formed at positions at distances corresponding to respective widths of hands of the user holding widthwise both ends of the roller sheet from both ends of the rolled sheet.

20. The recording apparatus according to claim 1 , further comprising:
a pressure contact body that comes, from below, into pressure contact with an outer peripheral surface of the rolled sheet contained in the containing portion; and
a lower guiding body provided vertically movable together with the pressure contact body depending on an outer diameter of the rolled sheet to guide a lower surface of the sheet pulled out of the rolled sheet on a downstream side of a position on the pressure contact body at which the pressure contact body is in the pressure contact with the outer peripheral surface in a direction of rotation of the
