Sheet Supplying Apparatus Lifting Member Cam Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet supplying apparatuses require high rigidity in the sheet receiving plate to handle recording sheets, which increases costs due to the need for materials with high strength and stiffness, and direct contact with cams further complicates the design.
Innovation Solution
A sheet supplying apparatus with a feed roller, a sheet receiving plate, a lifting member, and a cam, where the cam contacts the lifting member instead of the sheet receiving plate, allowing the sheet receiving plate to pivot between positions without needing high rigidity, thus reducing material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cam directly contacts the sheet receiving plate to position it, then the sheet receiving plate can be positioned accurately, but the sheet receiving plate must have high rigidity which increases material cost
Solution Approach 1:
The patent introduces a lifting member as an intermediary component between the cam and the sheet receiving plate. The cam contacts the lifting member instead of directly contacting the sheet receiving plate. The lifting member transfers the positioning force from the cam to the sheet receiving plate, allowing the sheet receiving plate to be positioned accurately without requiring high rigidity materials, thus reducing material cost.
2Strength
If the sheet receiving plate is made with high rigidity material to handle recording sheets, then the sheet receiving plate can maintain structural stability, but manufacturing cost increases
Solution Approach 1:
The lifting member serves as a mediator that bears the load from the cam and transmits it to the sheet receiving plate. This allows the sheet receiving plate to be constructed with lower rigidity materials since it only needs to support the recording sheet lightly, rather than withstand direct cam forces. The lifting member absorbs the structural stress, enabling cost reduction through material selection.
3Adaptability or versatility
If the sheet receiving plate is designed to pivot between nearby and remote positions, then sheet supply functionality is achieved, but the plate must withstand direct cam load which requires high rigidity
Solution Approach 1:
The lifting member is introduced as an intermediary that handles the load transmission during the pivoting motion. When the cam acts on the lifting member to pivot the sheet receiving plate between nearby and remote positions, the lifting member absorbs and transmits this force. This allows the sheet receiving plate to be designed with lower strength requirements while still achieving the necessary sheet supply functionality through the mediated force transmission.
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 the need for high-stiffness materials in the sheet receiving plate, lowering manufacturing costs while maintaining effective sheet handling and supply functionality.
Implementation Method 1
The cams are configured to rotate such as to contact or separate from the sheet receiving plate. When the cams are in contact with the sheet receiving plate, the cams are configured to position the sheet receiving plate in the remote position against urging forces of the urging members.
Implementation Method 2
The urging members are disposed under the sheet receiving plate and urge one end portion of the sheet receiving plate from the remote position toward the nearby position.

AI summary
A sheet supplying apparatus includes a feed roller, a sheet receiving plate, a lifting member, an urging member, and a cam. The sheet receiving plate is configured to pivot between a nearby position where the sheet receiving plate is disposed near the feed roller and a remote position where the sheet receiving plate is disposed remote from the feed roller. The lifting member is configured to pivot between a first position where the sheet receiving plate is in the nearby position and a second position where the sheet receiving plate is in the remote position. The urging member is configured to urge the lifting member from the second position toward the first position. The cam is configured to contact and move the lifting member from the second position to the first position when the feed roller feeds a sheet, and to move the lifting member to the second position again.
