Drum-Shaped ATM Media Alignment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic teller machines (ATMs) face challenges in accurately aligning paper media of different sizes and types, often resulting in creasing or tearing, and occupy significant space due to their flat alignment structures.
Innovation Solution
The development of an ATM with a drum-shaped medium alignment portion featuring driving rollers and inclined rollers, where the inclined rollers are adjustable to prevent interference and creasing, and a detection sensor ensures accurate alignment without folding, allowing for efficient alignment of cash and checks within a reduced footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a flat alignment structure is used, then the alignment function can be provided, but the ATM occupies significant space
Solution Approach 1:
The patent applies curvature by replacing the conventional flat alignment structure with a drum-shaped alignment portion. The drum shape allows the paper medium to be aligned on a curved surface, reducing the horizontal space required while maintaining alignment functionality. The drum rotates to transport the aligned paper medium through the recognition portion, achieving compact integration without sacrificing alignment accuracy.
2Reliability
If conventional alignment methods are used, then paper medium can be aligned, but creasing or tearing occurs
Solution Approach 1:
The patent applies preliminary action by providing the alignment function before the paper medium enters the recognition portion. The drum-shaped alignment portion aligns the paper medium in advance of its transport through the recognition area, ensuring proper positioning without requiring subsequent adjustment that could cause damage. This preliminary alignment prevents misalignment-related issues during later processing.
Solution Approach 2:
The patent applies dynamics by making the alignment portion rotatable as a drum. The rotation enables continuous transport of the aligned paper medium through the recognition portion while maintaining alignment. The dynamic rotational movement allows the system to process multiple sheets sequentially without stopping, preventing the paper from being subjected to repeated static adjustment forces that could cause creasing or tearing.
3Area of stationary object
If the ATM is reduced in size, then mounting becomes easier, but alignment of different paper medium sizes becomes challenging
Solution Approach 1:
The patent applies universality by designing the drum-shaped alignment portion to handle paper media of various sizes (e.g., checks and cash) with a single structure. The curved surface and rotational mechanism provide a universal alignment solution that accommodates different dimensions without requiring size-specific adjustment mechanisms, enabling the compact ATM to process diverse paper media types effectively.

AI summary
An automatic teller machine (ATM) including a medium receiving portion to receive a paper medium, a medium transfer portion to transfer the paper medium received through the medium receiving portion to a cassette as a storage space, and a medium alignment portion disposed on a transfer path of the medium transfer portion to align the paper medium. The medium alignment portion includes a drum-type alignment body including a transfer path connected to the transfer path of the medium transfer portion so that the paper medium passes through the transfer path in a rotating manner, and including an alignment reference surface to align the paper medium; driving rollers disposed in the alignment body to drive the paper medium forward along the transfer path; and inclined rollers disposed outside of the alignment body corresponding to the driving rollers, and selectively inclined from a transfer direction of the paper medium.
