Solution Overview
Problem
Existing document conveying devices face difficulties in easily switching between double-sided and single-sided reading specifications due to cumbersome lid attachments and detachment processes, making it hard to convert between modes efficiently.
Innovation Solution
A document conveying device with a recess and a cover member, supported by a supporting shaft, allows for detachable attachment of a member dedicated to double-sided reading and a cover member for single-sided reading, enabling easy switching between specifications while sharing common components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lid is used to cover the storage part for single-sided reading specification, then the device can be converted to single-sided reading mode, but the attachment and detachment work becomes difficult and time-consuming
Solution Approach 1:
The lid is divided into a lid body and a lid holder as separate components. The lid holder remains attached to the guide while the lid body can be easily attached or detached by simple insertion and engagement actions, transforming a difficult operation into an easy one through structural segmentation.
Solution Approach 2:
The lid holder acts as an intermediary component between the guide and the lid body. It provides engagement protrusions that fit into engagement grooves, serving as a mediator that simplifies the attachment and detachment process while maintaining the functional requirements of both the guide and the lid.
2Adaptability or versatility
If a dedicated member is attached to the storage part for double-sided reading, then the device can read both faces of documents, but the conversion back to single-sided reading becomes difficult
Solution Approach 1:
The dedicated member for double-sided reading is segmented into separable components that can be removed independently. This allows the device to switch between reading specifications by simply attaching or detaching specific components without complex disassembly procedures.
Solution Approach 2:
The guide structure is designed with universal features (engagement grooves, supporting shafts) that accommodate both the lid for single-sided reading and the dedicated member for double-sided reading. This multi-functional design allows the same base structure to support different configurations based on reading requirements.
3Reliability
If the lid adheres around the storage part, then it provides proper coverage, but the adherence makes detachment difficult
Solution Approach 1:
The lid structure is segmented into the lid body and lid holder, with the lid holder providing stable adherence to the guide while the lid body can be easily detached. This segmentation maintains reliable coverage through the adhered lid holder while enabling easy detachment of the lid body component.
Solution Approach 2:
The adherence function is extracted and assigned specifically to the lid holder component, which remains permanently or semi-permanently attached to the guide. The lid body component is designed without adherence features, allowing it to be easily attached or detached as needed for operation.

AI summary
A document conveying device is used in common for a double-sided reading specification in which images on one face and the other face of a document conveyed along a conveying path are read and for a single-sided reading specification in which the image on the one face of the document is read. The document conveying device includes a recess, a cover member and a supporting part. In the recess, a member dedicated to the double-sided reading specification is supported at the double-sided reading specification. The member dedicated to the double-sided reading specification is used for reading the image on the other face. The cover member closes the recess at the single-sided reading specification. By the supporting part, the member dedicated to the double-sided reading specification is detachably supported at the double-sided reading specification and the cover member is detachably supported at the single-sided reading specification.
