According to one embodiment, there is provided a printer including a print head, a platen roller, a sheet position sensor, an antenna, and a movable portion. The print head is configured to print on a strip-shaped sheet. The platen roller is configured to move the sheet pinched between the platen roller and the print head along a longitudinal direction of the sheet. The sheet position sensor is provided on a substrate disposed on an upstream side of the print head in a conveyance direction of the sheet, and is configured to detect a position of the sheet. The antenna is provided on the substrate and is configured to write information to a wireless tag provided on the sheet. The movable portion is configured to move the substrate along a width direction of the sheet.

A cassette tape includes: a cassette case; a first tape roll and a second tape roll accommodated in the cassette case and rotatably supported thereby; and an RFID tag disposed at one of an upper wall and a lower wall of the cassette case. The first tape roll includes a first tape wound about a first winding axis extending in an axial direction. The second tape roll includes a second tape wound about an axis different from the first winding axis and extending in the axial direction. The second tape roll has a smaller diameter than the first tape roll. The RFID tag includes an antenna and a storage element for radiocommunication to read and write data. A part of the RFID tag is positioned to overlap with a part of the first tape roll in a predetermined direction parallel to the axial direction.

A data writing device includes a roller configured to convey a label including a radio tag along a predetermined path, a reader/writer configured to wirelessly communicate with the radio tag, and a controller configured to control the roller to convey the label and control the reader/writer to acquire a plurality of radio wave intensities from the radio tag at different positions along the predetermined path as the label is conveyed, and determine one of the different positions along the predetermined path at which the radio wave intensities are equal to or greater than a threshold value as a writing position for the radio tag.

A tag writing device includes a conveying unit, an antenna, an acquiring unit, a determining unit, a selecting unit, and a deciding unit. The acquiring unit acquires reception intensities about a plurality of wireless tags. The determining unit determines an intermediate position between a start position and an end position as a position where a sum of reception intensities acquired while a mount is conveyed from the start position to the intermediate position and a sum of reception intensities acquired while the mount is conveyed from the intermediate position to the end position are closest. The selecting unit selects, as a target tag, the wireless tag, the intermediate position of which is determined as a position within a prediction range. The deciding unit decides a relative positional relation between the wireless tag and the antenna at a time when writing is performed.
