Image Recorder Cutter Lever for Quick, Safe Unit Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image recording apparatuses require complicated operations to attach or detach the cutter unit from the carriage, such as using screws or bolts, which is inefficient and cumbersome.
Innovation Solution
The image recording apparatus incorporates a lever that is swingably attached to the carriage, allowing easy attachment and detachment of the cutter unit by switching between a fixing and releasing position, eliminating the need for screw or bolt operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixing member such as screw or bolt is used to attach the cutter holder to the cutter base, then the cutter unit can be securely fixed to the carriage, but the attachment and detachment operations become complicated and time-consuming
Solution Approach 1:
The lever is designed to be swingable between a fixing position and a releasing position, transforming the static screw-bolt fixation system into a dynamic lever-based system. This allows the cutter unit to be quickly attached and detached by simply moving the lever between positions, eliminating the need for complicated screw or bolt operations while maintaining secure fixing during operation
Solution Approach 2:
The invention extracts the complex rotational operation of screws or bolts and replaces it with a simple lever swinging motion. The lever mechanism isolates the user from the complex fastening details, providing a user-friendly interface that requires minimal effort for attachment and detachment operations
2Ease of operation
If a lever mechanism is used to attach and detach the cutter unit, then the operation becomes simple and quick, but the device complexity increases
Solution Approach 1:
The lever mechanism serves multiple functions: it acts as both a fastening device and a position indicator. When the lever is in the fixing position, it secures the cutter unit to the carriage; when in the releasing position, it allows detachment. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity despite the added operational simplicity

AI summary
An image recording apparatus includes a conveyer configured to convey a sheet-like medium in a conveying direction along a conveying path, a recorder configured to record an image on the sheet-like medium conveyed by the conveyer, a cutter unit including a cutter and configured to cut the sheet-like medium in the conveying path, a carriage to which the cutter unit is detachably attached, and a lever swingably attached to the carriage. The lever is configured to swing between a fixing position for fixing the cutter unit to the carriage and a releasing position for releasing the fixing of cutter unit to the carriage.
