Image Forming Apparatus Job Information Selective Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing image forming apparatuses face a significant communication load when transmitting and reading job information due to the large size of job information items, leading to inefficient data transfer and unnecessary data retrieval.
Innovation Solution
An image forming apparatus with a first storage section for job information and a second storage section for read-out definition information, which allows for selective extraction and output of specific data items based on user instructions, reducing unnecessary data transfer by using a control section to filter and output only the required data items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If job information is transmitted to an external device through a network, then job information can be managed and displayed, but communication load increases due to the large size of job information items
Solution Approach 1:
The patent extracts and stores only the necessary data items from complete job information into a separate data item storage section. When job information is read out, only these extracted data items are transmitted through the network, significantly reducing communication load while maintaining the ability to manage and display job information effectively.
2Loss of information
If all job information items are read out from external device, then complete job information is obtained, but unnecessary communication load occurs due to reading items not needed by user
Solution Approach 1:
The patent implements local quality by allowing different data items to be treated differently based on their necessity. The read-out definition information specifies which data items should be read out and transmitted, enabling selective data retrieval that matches actual user needs while maintaining completeness of essential job information.
3Adaptability or versatility
If complete job information is transmitted and stored externally, then all data is available for any purpose, but data retrieval speed decreases due to processing large data volumes
Solution Approach 1:
The patent segments job information into two parts: complete job information stored in the job log recording section, and extracted essential data items stored in a separate data item storage section. This segmentation enables fast retrieval of essential data while preserving the complete information for when it is needed, thus improving retrieval speed without sacrificing data availability.

AI summary
Disclosed is an image forming apparatus, including: a first storage section to store a plurality of pieces of job information each having a plurality of data items corresponding to a plurality of items; a second storage section to store read-out definition information in which one or more of the items to be read out from each of the pieces of job information are set; an input section to input an instruction to read out one or more of the pieces of job information; and a control section to extract one or more of the data items corresponding to one or more of the items set in the read-out definition information from each of the one or more of the pieces of job information when the instruction is inputted by the input section, and to output the extracted one or more of the data items.
