Single-Motor Paper Conveying Apparatus with Straddling Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper conveying apparatuses require multiple motors to drive rollers and guides, leading to increased size and cost due to the need for separate motor systems for paper feed, retard, and conveyor rollers.
Innovation Solution
A paper conveying apparatus that utilizes a single motor to drive paper set guides, paper feed rollers, retard rollers, and conveyor rollers through a transmission mechanism arranged straddling the paper transport path, eliminating the need for multiple motor systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple motors are used to drive paper set guides, paper feed rollers, retard rollers, and conveyor rollers separately, then each component can be driven independently, but the apparatus becomes larger in size and higher in price
Solution Approach 1:
The patent combines multiple drive functions into a single motor system. The conveyor roller and paper feed rollers are both driven by one motor through a transmission mechanism, eliminating the need for separate motors for each component. This merging approach reduces the overall apparatus size while maintaining the ability to drive different components.
Solution Approach 2:
The single motor is designed to perform multiple functions by driving different components through a transmission mechanism. The motor can selectively convey drive operation to either the conveyor roller or the paper feed rollers via a drive coupling means, making it a universal drive source that replaces multiple specialized motors.
2Ease of operation
If multiple motors are mounted to drive different rollers, then each roller can be controlled independently, but the apparatus becomes higher in price
Solution Approach 1:
The patent merges multiple motor functions into a single motor system with a transmission mechanism. This consolidation reduces the number of expensive motor components needed while maintaining independent control capability through the drive coupling means that can selectively engage different drive modes.
Solution Approach 2:
The transmission mechanism acts as an intermediary between the single motor and the multiple rollers. It includes a drive coupling means that selectively transmits drive operation to different components, enabling independent control without requiring multiple motors. This intermediary structure reduces cost while preserving control flexibility.
3Area of stationary object
If a transmission mechanism is arranged straddling the paper transport path to drive multiple components from a single motor, then the apparatus size is reduced, but the mechanism becomes more complex
Solution Approach 1:
The transmission mechanism is arranged straddling the paper transport path, utilizing the vertical or lateral dimension rather than expanding the horizontal footprint. This spatial arrangement reduces the apparatus size by using unused dimensional space, while the mechanism itself remains relatively simple through careful design.

AI summary
There are provided a paper conveying apparatus which can drive paper set guides, paper feed rollers, retard rollers, and conveyor rollers by a single motor. The paper conveying apparatus includes a paper set guide for setting paper, a paper feed roller for feeding paper set at the paper set guide, a retard roller arranged facing the paper feed roller, a conveyor roller for further conveying paper fed by the paper feed roller, a motor for generating a drive force for driving the paper set guide, and a transmission mechanism, arranged straddling a transport path of the paper, for transmitting the drive force to the paper feed roller and the retard roller, wherein the conveyor roller is driven by the transmission mechanism.
