AI Technical Summary

Technical Problem

Conventional printers face challenges in positioning the RFID antenna on the label printing side of the continuous paper, especially when attaching labels to conductive materials like metal, as electromagnetic wave cancellation occurs, necessitating a reconfiguration to enable effective communication with the RFID inlay.

Method used

The printer is designed with an antenna positioned on the oscillating member on the print surface side of the printing medium, upstream of the heating element, and integrated with an antenna cover to manage electromagnetic waves, ensuring efficient communication and space utilization.

Benefits of technology

This configuration allows for effective communication with RFID inlays on the label printing side, prevents electromagnetic interference, and optimizes space efficiency by positioning the antenna close to the heating element, thereby improving throughput and reducing waste.

Abstract

The present invention provides a printer configured to position the antenna on the printing surface side of the printing medium. [Solution] A printer according to one aspect of the present invention comprises a transport roller for transporting a printing medium having an RFID inlay, a print head having a heating element for printing information on the printing medium, a oscillating member that can oscillate around an oscillating axis parallel to the rotation axis of the transport roller, and an antenna capable of communicating with the RFID inlay. The antenna is positioned on the oscillating member on the print surface side of the transported printing medium and upstream of the heating element position of the print head in the transport direction of the printing medium.
