Rotating Print Head for Dual-Side ATM Document Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current banking machines lack the capability to efficiently print on both sides of documents, limiting their functionality in deposit processing and account crediting processes.
Innovation Solution
An automated transaction machine (ATM) with a printer that rotates to print on both sides of a document by moving between two positions, allowing for printing on the first side when facing one direction and the second side when facing another, enabling comprehensive document processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single print head is used for printing, then device complexity is reduced, but the capability to print on both sides of documents is limited
Solution Approach 1:
The print head is made rotatable about a printer axis, allowing it to dynamically change its orientation between a first position for printing on the first side of the document and a second position for printing on the second side. This dynamic repositioning enables a single print head to perform dual-sided printing without requiring two separate print heads, thus reducing device complexity while maintaining versatile printing capability.
2Adaptability or versatility
If the printer rotates to print on both sides, then printing versatility is improved, but the operational complexity increases
Solution Approach 1:
The rotation of the print head is merged with the document transport cycle. The document spool rotates the document so that the first side faces toward the spool axis, and simultaneously the printer rotates to the second position. This merging of motions allows the system to print on both sides of the document automatically during the normal transport cycle, maintaining ease of operation while achieving dual-side printing capability.
3Productivity
If a document spool is used to rotate the document, then document handling efficiency is improved, but device complexity increases
Solution Approach 1:
The document spool serves multiple functions: it transports the document through the printer, rotates the document to present the first side to the print head, and simultaneously enables the print head to rotate to the second position for back-side printing. This multi-functionality allows a single component to handle document processing efficiently without requiring separate mechanisms for each function, thus improving productivity while limiting the increase in device complexity.

AI summary
An automatic transaction machine (ATM) prints on both sides of a document having a first side and a second side. A printer rotates about a printer axis allowing the printer to move between a first positon and a second position. A transport moves a document adjacent the printer in the first position. While in the first position the printer is configured to print on a first side of the document as the document passes the printer on the transport. A document spool with a spool axis receives the document from the transport and at least partially rotates the document so the first side of the document is facing toward the spool axis. The printer rotates about the printer axis to the second position to print on the second side of the document that is facing outward away from the spool axis.
