Recording Apparatus Rolled Sheet Guide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses face issues with ensuring the attachability of rolled sheets while preventing discharged sheets from entering the rolled sheet feeding portion, leading to potential jams.
Innovation Solution
A recording apparatus with a containing portion for rolled sheets, a recording portion for image printing, and an opening/closing member with a guiding portion to securely attach and cover the rolled sheet feeding portion, utilizing a spool member and rotary door mechanism to facilitate easy sheet loading and prevent jams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the containing portion is opened to the front side to allow easy attachment of rolled sheet, then the ease of operation is improved, but discharged sheet may enter the rolled sheet feeding portion causing jams
Solution Approach 1:
The opening/closing member is divided into a first opening/closing member for the containing portion and a second opening/closing member for the discharged sheet discharge portion. This segmentation allows independent control of each opening, enabling the containing portion to remain open for easy rolled sheet attachment while the discharged sheet discharge portion can be closed to prevent jams.
Solution Approach 2:
A guiding portion is provided in the first opening/closing member to guide the rolled sheet to the containing portion. This intermediary structure facilitates easy attachment of rolled sheets while the closed position of the first opening/closing member prevents discharged sheets from entering the feeding portion.
2Ease of operation
If the guiding portion protrudes from the front side to facilitate rolled sheet placement, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The guiding portion is integrated into the first opening/closing member, merging the guiding function with the opening/closing mechanism. This reduces device complexity by eliminating separate guiding structures while maintaining ease of rolled sheet placement through the protruding guiding portion.

AI summary
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.
