Cam Member Gap Adjustment Pressing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses face challenges in regulating the movement of cam members with respect to carriages during capping, leading to increased loads and potential instability in gap adjustments, which can affect recording quality.
Innovation Solution
Incorporating a pressing member that intersects with the cam member's movement direction relative to the carriage and sliding member, allowing for reduced press forces and preventing cam member movement relative to the housing, thereby stabilizing the gap adjustment process with lower loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a bias member is used to bias the sliding member to the carriage with the cam member interposed therebetween, then the cam member is maintained in position, but the bias force acts as a load on the gap adjusting unit during gap switching
Solution Approach 1:
The pressing member is configured to press the cam member in a direction intersecting with both the first direction (carriage movement direction) and the second direction (gap changing direction). This dimensional change in pressing direction allows the pressing force to have stabilizing effect without acting as load during gap switching operation
2Reliability
If the cap member is made movable to cap the recording head, then the recording head is protected, but the carriage may separate from the guide member during capping
Solution Approach 1:
The pressing member pre-presses the cam member to the housing in a direction intersecting with the gap changing direction, creating preliminary counter-action that prevents the carriage from separating from the guide member when the cap member moves during capping operation
3Adaptability or versatility
If the cam member moves relative to the sliding member to adjust the gap, then the gap can be changed, but the cam member may move unexpectedly during acceleration and deceleration
Solution Approach 1:
The pressing member presses the cam member in a direction intersecting with both the first direction (carriage movement) and second direction (gap changing), creating stabilizing pressure that prevents unexpected cam member movement during acceleration and deceleration while preserving gap adjustment capability
Solution Approach 2:
The pressing member acts as an intermediary that mediates between the cam member and housing, providing continuous stabilizing pressure that prevents relative movement during dynamic operation while allowing controlled movement for gap adjustment
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces loads during gap switching and prevents torsion, ensuring stable recording quality by maintaining the cam member's position relative to the carriage and sliding member, even during acceleration and deceleration.
Implementation Method 1
a pressing member that presses the cam member to the housing of the carriage in a second direction intersecting with the first direction and the direction in which the gap is changed
Implementation Method 2
a cam member that is interposed between a part of the housing and the sliding member and has a shape with which the housing of the carriage is caused to shift in the direction in which the gap is changed, by moving in the first direction relative to the housing and the sliding member
Implementation Method 3
a sliding member that slides over an upper side of the guide member in response to a movement of the carriage

AI summary
A recording apparatus includes: a carriage that has a housing in which a recording head is provided; a guide member that guides the carriage; a gap adjusting unit that adjust a gap between the medium and the recording head; and a cap member by which the recording head is capped. The gap adjusting unit includes a sliding member that slides over the guide member, a cam member that is interposed between a part of the housing and the sliding member and has a shape with which the housing is caused to shift in the direction in which the gap is changed, by moving in the first direction relative to the housing and the sliding member, and a pressing member that presses the cam member to the housing of the carriage in a second direction intersecting with the first direction and the direction in which the gap is changed.
