Retractable Positioning Portion for Flexible Binding in Post-Processing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing post-processing devices obstruct the movement of binding sections when attempting to perform post-processing at positions other than the designated stop position, limiting flexibility and efficiency in binding operations.
Innovation Solution
A post-processing device with a movable post-processing section and a positioning portion that retracts when passing through or moving towards the stop position, allowing for binding operations at multiple positions without obstructing the movement of the binding sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a positioning portion is provided at the stop position to enable post-processing at multiple positions, then the versatility and processing capability are improved, but the movement of the post-processing section is obstructed when passing through or moving toward the stop position
Solution Approach 1:
The positioning portion is designed to be movable rather than fixed, allowing it to change its state between extended and retracted positions. This dynamic characteristic enables the positioning portion to adapt to different operational requirements: extending to provide positioning when needed and retracting to allow smooth movement of the post-processing section, thereby resolving the contradiction between versatility and movement smoothness
Solution Approach 2:
The control unit causes the positioning portion to be retracted in advance before the post-processing section arrives at the stop position, and extends it in advance after passing through. This preliminary action prevents obstruction during movement while ensuring positioning capability is available when the section stops, resolving the conflict between movement ease and positioning functionality
2Productivity
If the post-processing section stops at multiple positions to perform different post-processing operations, then the productivity and processing capability are improved, but the device complexity increases
Solution Approach 1:
The positioning portion serves multiple functions: it provides positioning support at the stop position, allows smooth passage during movement, and can be controlled to extend or retract based on operational needs. This multi-functionality enables the system to achieve enhanced productivity through multiple stop positions without proportionally increasing device complexity
Solution Approach 2:
The control unit acts as an intermediary that coordinates between the post-processing section's movement and the positioning portion's state. It manages the timing of extension and retraction, enabling the system to achieve complex multi-position processing capability while keeping the control mechanism relatively simple through centralized coordination

AI summary
A post-processing device includes: a passage that extends in one direction; a post-processing section that is movable on a plane along the passage and that is stopped at plural post-processing positions, including a stop position determined in advance, to perform post-processing on a recording medium; and a positioning portion which is provided at the stop position and against which an end portion of the recording medium abuts when the post-processing section performs the post-processing at a post-processing position other than the stop position, the positioning portion being retracted with respect to the post-processing section when the post-processing section passes through the stop position or is moved toward the stop position.
