Copying Apparatus Synchronizes Capture and Formation Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current copying apparatuses face inefficiencies in capturing and processing images due to the lack of precise timing synchronization between image capture and formation processes, leading to suboptimal use of storage capacity and varying processing times based on image size.
Innovation Solution
The apparatus includes a synchronizing circuit that determines capture start times by calculating and instructing the scanner and print engine to align image capture and formation processes with the estimated arrival time of the medium at the image forming position, accounting for capture, write, read, and process times to optimize storage usage and timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If image capture and formation processes are performed without precise timing synchronization, then the system is simpler to operate, but storage capacity is wasted and processing efficiency decreases
Solution Approach 1:
The instruction unit determines the capture start time in advance based on the size of image data and instructs the capturing unit to start capturing at that predetermined time. This preliminary timing calculation and instruction ensures that image capture and formation processes are synchronized without requiring complex real-time coordination mechanisms.
2Loss of time
If image data is captured and stored without considering timing synchronization, then the capturing process is simpler, but storage requirements increase and processing time varies
Solution Approach 1:
The system dynamically adjusts the capture start time based on the size of image data. The instruction unit calculates the appropriate capture start time according to the specific data size, allowing the timing to adapt to varying image requirements. This dynamic timing adjustment optimizes both storage utilization and processing efficiency for different image sizes.

AI summary
A copying apparatus includes a capturing unit that divides an image on a document into plural regions and captures an image of each region, a storage unit that stores data representing the image of the region, a forming unit that reads the data and forms an image represented by the data on a medium, and an instruction unit that determines a capture start time on the basis of a size of the data and instructs the capturing unit to start capturing the image at the capture start time.
