AI Technical Summary

Technical Problem

Conventional printers face challenges in effectively limiting the communication range of RFID antennas due to insufficient ground function, leading to unintended electromagnetic emissions and incorrect communication with non-intended labels, exacerbated by miniaturization and improved antenna output.

Method used

A printer design incorporating an antenna cover electrically connected to the printer body, which blocks electromagnetic waves and enhances the ground function of the antenna, positioned to restrict communication range and prevent unintended interactions.

Benefits of technology

The solution effectively improves the ground function of the antenna, preventing unintended communication and ensuring accurate data transfer to intended RFID inlays while maintaining space efficiency.

Abstract

In printers, this improves the functionality of the ground for the RFID inlay and the antenna capable of communicating with it. [Solution] A printer according to one aspect of the present invention comprises a printer body, a transport roller for transporting a printing medium having an RFID inlay, an antenna capable of communicating with the RFID inlay, and an antenna cover that blocks at least a portion of the electromagnetic waves emitted from the antenna. The antenna cover is electrically connected to the printer body.
