Wireless tag writing device, calibration method and storage medium

Abstract

The present invention discloses a wireless tag writing device, a calibration method, and a storage medium. The wireless tag writing device comprises: a conveyance unit for conveying a sheet on which awireless tag is provided; a transmission unit that is disposed on the conveyance path of the sheet and transmits a first radio wave for communicating with the wireless tag; a reception unit that receives a second radio wave transmitted from the wireless tag in response to the first radio wave; a measuring means for reducing a radio wave intensity of a specific level excluding a minimum level fromamong radio wave intensities of a plurality of levels transmittable by the transmitting unit to a radio wave intensity of a level at which the radio wave intensity of the second radio wave received by the reception unit is less than a threshold value every time the conveyance unit conveys a predetermined amount of the sheet and acquiring a set of the radio wave intensity of the first radio wave and the radio wave intensity of the second radio wave; and a deriving means for deriving a writing condition for writing of the wireless tag based on the set of the radio wave intensity of the first radio wave and the radio wave intensity of the second radio wave acquired for each conveying position of the sheet.

Description

[0001] This application claims the priority of the Japanese application with the application date of August 19, 2019 and the application number JP2019-150003, and cites the content of the above application, which is incorporated herein by reference in its entirety. technical field [0002] Embodiments of the present invention relate to a wireless tag writing device, a calibration method and a storage medium. Background technique [0003] In a printer device that prints on label paper to which a wireless tag such as an RFID (Radio Frequency Identification) tag is attached, the following processing is performed when determining a writing condition of the wireless tag. First, the actually used wireless tags are transported at a predetermined transport pitch. When stopping at each delivery position, radio waves are sequentially transmitted at a plurality of radio wave strengths, and the radio wave strength of the response wave received from the wireless tag is recorded in associ...

AI Technical Summary

Problems solved by technology

[0006] However, in the above-mentioned conventional method, radio waves are transmitted even at a level of radio wave strength that is predicted to be unresponsive from the wireless tag, so there is a problem that it takes time and is inefficient.
