Scan Object Position Detection for Multifunction Printer Function Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multifunction printers require user intervention via peripheral devices to perform functions like enlarging and emailing scan images, reducing user convenience.
Innovation Solution
An image forming apparatus with a user interface that includes a scan area divided into a determination area and a function area, using a contact image sensor to determine the position of a scan object and automatically select corresponding functions stored in the system, allowing for direct performance of scanning, printing, and transmission operations without external device connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multifunction printer supports scanning, printing, and faxing functions, then the device functionality is improved, but user convenience deteriorates because peripheral devices are required to perform functions like enlarging and emailing scan images
Solution Approach 1:
The multifunction printer integrates scanning, printing, faxing, and image processing capabilities into a single device. The image reading unit can scan documents and the control unit can automatically perform functions like enlarging and emailing scan images without requiring external peripheral devices, making the printer a universal device that handles multiple tasks independently.
Solution Approach 2:
The printer performs image processing functions autonomously. When a scan object is placed in specific positions on the scan area, the control unit automatically determines the object's position and executes corresponding functions such as enlarging or emailing the scan image without user intervention or connection to peripheral devices like PCs.
2Productivity
If a PC is connected to the multifunction printer to handle functions like enlarging and emailing, then the processing capability is improved, but device complexity increases due to the need for external connections and application programs
Solution Approach 1:
The patent merges the image processing capabilities previously requiring external PC connections into the printer itself. The control unit integrates functions for determining scan object position, selecting corresponding operations, and executing tasks like enlarging and emailing directly within the printer system, eliminating the need for external PC connections and reducing overall system complexity.
Solution Approach 2:
The control unit acts as an intermediary that receives scan data from the image reading unit, determines the position of the scan object on the scan area, selects the appropriate function based on position, and executes the function automatically. This intermediary processing within the printer eliminates the need for external PC mediation.

AI summary
An image forming apparatus includes a user interface unit that includes a scan area, an image reading unit that reads an image of a scan object disposed on the scan area, a driving unit that moves the image reading unit, a control unit that controls a function according to a position of the scan object, an operation performing unit that performs the function by using the read image, and a storage unit that stores information about the function corresponding to the position of the scan object. The scan area includes a determination area and a function area, and when it is determined that the scan object does not exist on the determination area, the control unit controls the operation performing unit to perform the function corresponding to the position of the scan object on the function area.
