Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media ejecting apparatuses face challenges in aligning media ejected to a tray without distortion, as changes in ejection speed affect the interval between imaged positions, leading to image distortion and requiring user intervention to align scattered media.
Innovation Solution
A media ejecting apparatus with an imaging device, an ejection roller, and sensors to detect the medium's inclination, determining if the trailing end has passed the imaging position and controlling the ejection roller to prevent distortion and alignment issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ejection speed of media is changed to align the media ejected to the ejection tray, then the alignment of media is improved, but the interval between imaged positions in a medium changes resulting in distortion in the generated image
Solution Approach 1:
The system performs preliminary detection of media inclination using a sensor before the media reaches the ejection roller. Based on this advance detection, the control unit calculates the required ejection speed adjustment and prepares the correction in advance, allowing alignment without affecting already-imaged portions of the media
Solution Approach 2:
The ejection speed is made dynamically adjustable based on real-time detection of media inclination. The control unit varies the ejection speed according to the detected inclination angle, enabling adaptive alignment that responds to actual media conditions while maintaining image quality
2Ease of operation
If the ejection speed is adjusted to correct media inclination, then media alignment is improved, but the timing of when the trailing end passes the imaging position becomes uncertain
Solution Approach 1:
The sensor detects media inclination in advance before the media reaches the ejection roller. The control unit uses this advance information to determine the appropriate ejection speed adjustment, ensuring that by the time the trailing end reaches the sensor, the correction has already been applied and the timing is predictable
Solution Approach 2:
The system implements a feedback mechanism where the sensor continuously monitors media inclination and provides real-time information to the control unit. The control unit adjusts the ejection speed based on this feedback, creating a closed-loop control system that maintains precise timing and detection accuracy

AI summary
A media ejecting apparatus includes: an imaging device to image a medium to generate an input image, an ejection roller located downstream from the imaging device in a media ejection direction to eject the medium imaged by the imaging device, a sensor located between the imaging device and the ejection roller to detect a part of a trailing end of the medium, and circuitry. The circuitry detects an amount of inclination of the medium. The circuitry determines whether an entire trailing end of the medium has passed an imaging position of the imaging device based on the amount of inclination when a part of the trailing end of the medium passes the sensor and generate a determination result. The circuitry controls the ejection roller based on the determination result.
