Image Transmission Apparatus External Request Stop Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image transmission systems face issues where facsimile transmissions are inadvertently stopped by users operating the image forming apparatus directly, leading to unintended cessation of transmissions initiated by other users, particularly when instructions are received from external apparatuses.
Innovation Solution
The image transmission apparatus includes an acquisition unit for acquiring image data and a destination identifier, a transmission unit for sending data, a receiving unit for stop instructions, and a processing unit that performs stop processing and stop prevention processing based on flags indicating the origin of the transmission request, ensuring that transmissions from external apparatuses are not stopped unintentionally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image transmission apparatus allows stop instructions to be received during transmission, then users can control transmission stopping, but transmissions initiated by external apparatuses may be inadvertently stopped by direct operation of the image forming apparatus
Solution Approach 1:
The patent applies local quality by differentiating the stop instruction handling based on the source of the transmission request. When the transmission request originates from an external apparatus, the stop instruction is ignored, whereas requests from internal sources can be stopped. This is implemented through determining whether the transmission request is from an external apparatus and accordingly deciding whether to stop the transmission or not, ensuring that external transmissions maintain continuity while internal transmissions remain controllable.
2Productivity
If the apparatus performs stop processing when stop instructions are received, then transmission can be halted when needed, but intended transmissions from external apparatuses cannot be maintained
Solution Approach 1:
The patent implements dynamics by making the stop processing behavior adaptive based on the transmission request source. The system dynamically adjusts its response to stop instructions: when the request is from an external apparatus, stop processing is prevented; when from an internal source, stop processing is allowed. This dynamic adjustment ensures that productivity is maintained for internal operations while reliability is preserved for external transmissions.
3Ease of operation
If the system allows direct operation of the image forming apparatus, then users can control transmissions, but unintended stoppage occurs when other users are using the apparatus
Solution Approach 1:
The patent introduces an intermediary mechanism that mediates between user control and transmission continuity. The determining unit acts as an intermediary by checking the source of the transmission request before allowing stop processing. This intermediary layer prevents harmful unintended stoppage by blocking stop instructions during external transmissions while still allowing user control for internal transmissions, thus resolving the conflict between ease of operation and prevention of harmful effects.

AI summary
An image transmission apparatus includes an acquisition unit that acquires image data and an identifier for identifying a transmission destination, a first transmission unit that transmits the image data to a transmission destination identified by the identifier, a receiving unit that receives a stop instruction for stopping the transmission while the first transmission unit is transmitting the image data, and a processing unit that when a transmission request of the image data is received from a host apparatus, performs stop processing for stopping the transmission when the receiving unit receives the stop instruction and performs stop prevention processing for preventing the stop processing from being performed or the stop instruction from being received when the transmission request of the image data is received from an external apparatus.
