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; 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.

2 . The recording apparatus according to claim 1 , further comprising a discharge portion that discharges the sheet, on which the image is recorded by the recording portion, above the containing portion,
wherein, at the closed position, the opening/closing 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 opening/closing 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 opening/closing 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 a discharge portion that discharges the sheet on which the image is recorded by the recording portion.

16 . The recording apparatus according to claim 15 ,
wherein the open position is a position at which the opening/closing member is in a posture horizontally protruding from an apparatus side surface provided with a discharge port of the discharge portion and the inner surface is upwardly open, and wherein the closed position is a position at which the opening/closing 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 15 ,
wherein the outer surface is an exterior surface forming a portion of an apparatus side surface provided with a discharge port of the discharge portion in a case where the opening/closing member is at the closed position.

18 . 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; and a first opening/closing member provided correspondingly to the first containing portion and a second opening/closing member provided below the first opening/closing member correspondingly to the second containing portion, the first opening/closing member and the second opening/closing member serving as the opening/closing member, the recording apparatus further comprising: a restricting portion that restricts the sheet discharged from the discharge portion from advancing in a gap between the first opening/closing member and the second opening/closing member.

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

20 . The recording apparatus according to claim 19 ,
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 the both ends of the rolled sheet.

21 . 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 provid
