Scanner Tilt Panel Division Reading Large Document Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multifunction printers face difficulties in efficiently reading and recording large documents, as they require multiple operations and can obstruct operation portions, leading to poor operability and visibility issues.
Innovation Solution
A recording apparatus with a division reading mode that allows sequential image linking without document rotation, utilizing a scanner portion, recording portion, and control portion to manage large documents by initiating reading from a reference position and guiding the document through a gap to improve operability and prevent obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple reading operations are performed to read large documents, then the entire document image can be obtained, but the user is required to rotate the document which deteriorates operability
Solution Approach 1:
The patent applies segmentation by dividing the reading process into multiple sequential operations that read different portions of the document in one continuous direction. Instead of requiring the user to rotate the document, the system segments the reading task into multiple passes along the same axis, with the control portion automatically linking the images to reconstruct the complete document image.
2Device complexity
If the document reading area is kept compact, then the apparatus structure is simplified, but large documents cannot be read without obstruction
Solution Approach 1:
The patent resolves this contradiction by utilizing the time dimension through multiple sequential reading operations. The compact document reading area maintains its simple structure, while the system achieves large document reading capability by performing multiple reads in sequence along the length direction, effectively extending the readable area through temporal multiplication rather than spatial expansion.
3Area of stationary object
If the scanner portion is positioned above the recording portion, then the apparatus is compact, but the pushed-out document covers the ejected sheet making confirmation difficult
Solution Approach 1:
The patent applies the extraction principle by separating the document output path from the recording sheet ejection path. The pushed-out document is guided through a specific route that extracts it from the area where the recorded sheet is ejected, preventing the document from covering the recorded image and allowing easy confirmation of the recording result.
4Productivity
If the document is pushed out from the scanner portion, then the reading operation is completed, but the document covers the operation portion deteriorating operability
Solution Approach 1:
The patent introduces an intermediary guiding structure that mediates between the document reading completion and operation portion accessibility. This guiding structure directs the pushed-out document along a predetermined path that bypasses the operation portion, allowing the document to be efficiently processed and removed without obstructing the user interface.

AI summary
A printer includes a scanner unit which reads a document; a recording portion which records information read by the scanner unit; and a tilt panel which constitutes the scanner unit and an operation portion of the recording portion. A printer executes a division reading mode which obtains image information of the entire document by linking image information obtained via a plurality of times of a document reading operation, with respect to the document of which the size is greater than the size of the document reading area. The image information of the entire document can be obtained by sequentially linking a predetermined image position of an ending position side of an image obtained by a first document reading operation and a predetermined image position of an initiating position side of an image obtained by the following document reading operation, in a linking direction of the image.
