Printer Stacker Automatic Housing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing devices require manual operation to house the stacker inside the device main body, which increases user burden and reduces usability, especially when the stacker projects outside the device main body or when cassette detachment is required.
Innovation Solution
A printing device equipped with a drive device and control device that automatically changes the stacker's state from projecting to housed, allowing for automatic housing when specific conditions are met, such as power-off requests, cassette detachment, or size mismatches between requested and available printing media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stacker projects outside the device main body to receive printed media, then the usability for media collection is improved, but the user burden increases due to manual housing operation required
Solution Approach 1:
The stacker performs self-service by automatically housing itself inside the device main body when the housing condition is established. The control device detects the housing condition and controls the drive device to move the stacker from the projecting state to the housed state, eliminating the need for manual user intervention in the housing operation.
2Productivity
If the stacker projects outside the device main body, then media discharge capability is improved, but interference with operation device occurs during power-off or media changes
Solution Approach 1:
The control device continuously monitors the housing condition and uses this feedback to determine when to initiate the automatic housing operation. When the housing condition is established (such as during power-off requests, cassette detachment, or size mismatches), the control device automatically triggers the drive device to house the stacker, preventing interference with operation device activities.
3Measurement precision
If manual housing operation is required, then device control precision is maintained, but time and effort consumption increases
Solution Approach 1:
The system performs preliminary detection of the housing condition and prepares for automatic housing before the user would need to manually intervene. The control device monitors conditions such as power-off requests, cassette detachment status, and printing medium size mismatches, and initiates the housing operation automatically when these conditions are detected, saving user time and effort.

AI summary
A printing device includes a printing mechanism configured to print a printing medium fed to a printing area in a device main body, a stacker configured to receive the printing medium discharged from the printing area, a drive device configured to cause a state of the stacker to be a housed state in which the stacker is housed in the device main body and a projecting state in which the stacker is positioned outside the device main body, and a control device configured to change the state of the stacker from the housed state to the projecting state by controlling the drive device. When a housing condition is established while the state of the stacker is the projecting state, the control device is configured to perform an automatic housing process to change the state of the stacker to the housed state by controlling the drive device.
