Receipt Printer Partial Cutting for Unclaimed Receipt Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In semi-self-service and self-service type settlement terminals, unclaimed receipts often remain in the receipt issuing port, causing issues for subsequent users and requiring additional equipment for collection, which is costly.
Innovation Solution
A receipt printer system that performs partial cutting of receipts, allowing them to remain connected to the sheet roll, and automatically performs full cutting after a predetermined time or upon detection of the next user, ensuring receipts are removed without additional equipment costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If full cutting is performed to separate the receipt completely, then the receipt is fully separated for user collection, but the receipt may fall from the issuing port and be lost
Solution Approach 1:
The patent applies partial cutting instead of full cutting by controlling the cutter to cut only a portion of the receipt sheet. This partial cutting prevents the receipt from completely separating and falling from the issuing port, while still allowing users to easily grasp and collect the receipt by pulling it from the issuing port.
2Reliability
If partial cutting is performed to prevent receipt loss, then the receipt remains connected to the sheet roll, but the unclaimed receipt remains in the issuing port and obstructs subsequent transactions
Solution Approach 1:
The system performs preliminary full cutting automatically after a predetermined time period or when the next transaction is detected. This preliminary action ensures that unclaimed receipts are removed from the issuing port before they can obstruct subsequent transactions, while previously maintaining receipt retention through partial cutting during the waiting period.
3Productivity
If a separate device is installed to collect unclaimed receipts, then the receipt collection problem is solved, but the equipment cost increases
Solution Approach 1:
The cutter, which is an existing component in the receipt printer, is made to perform multiple functions: partial cutting to retain receipts during normal operation, and full cutting to remove unclaimed receipts. This eliminates the need for separate receipt collection devices, reducing equipment complexity and cost while maintaining productivity.
4Reliability
If the receipt remains partially connected to the sheet roll, then the receipt does not fall from the issuing port, but the user must pull the tip to detach it which may cause confusion
Solution Approach 1:
The cutter is controlled to perform partial cutting that separates the receipt from the sheet roll by a specific distance, leaving a small connected portion. This partial cutting creates a clear separation point that allows users to easily grasp and pull the receipt from the issuing port without confusion, while still maintaining enough connection to prevent complete loss.
Data Source
AI summary
A receipt printer according to an embodiment includes a sheet roller that transports a sheet from a sheet roll to a receipt issuing port. A printing device prints receipt data on the sheet. A cutter configured performs full cutting so that the sheet is separated from the sheet roll and partial cutting so that the sheet remains partially connected to the sheet roll. A processor controls the cutter to perform the partial cutting after the printing device prints the receipt data on the sheet, and also controls the cutter to perform the full cutting when a predetermined condition is satisfied after the partial cutting is performed.
