In particular, the present invention relates to an RFID paper, RFID capable of eliminating wasteful forward / reverse transport operations for RFID paper, and RFID The present invention relates to a paper printer and a method for transferring RFID paper.

    Conventionally, RFID paper that has an IC chip and an RFID antenna and can write and read data wirelessly is in the form of a label or tag, and various data on various items is read and written to provide necessary data. It is used in various fields such as management.

FIG. 3 is a schematic side view of an RFID paper printer (for example, a thermal printer 2) for loading a conventional RFID paper 1 to perform transfer, data communication, and printing, and FIG. 4 is a plan view of the RFID paper 1. 5 is a rear view of the RFID paper 1, and FIG. 6 is a sectional view taken along line VI-VI in FIG.
In particular, as shown in FIGS. 4 to 6, the RFID paper 1 is configured as a continuous label body, for example, and has a belt-like paper body 3 and an RFID inlet 4.

The paper body 3 is provided in a state in which a plurality of single-sheet paper pieces (label pieces 6) are continuously and temporarily attached to a belt-like mount 5. However, the adjacent label pieces 6 can be temporarily attached to each other by providing a gap between them or connecting them to each other as necessary.
That is, the label piece 6 has an adhesive layer 7 on the back side thereof, and is temporarily attached to the mount 5, and the RFID inlet 4 is disposed between the mount 5 and the RFID inlet 4. 4 can be attached to a predetermined managed object (not shown).
The label piece 6 has a transfer direction front end portion 6A and a transfer direction rear end portion 6B, and is located on the back side of the mount 5 at a position corresponding to the transfer direction rear end portion 6B of the label piece 6. The mark 8 is printed in advance.

The RFID inlet 4 includes an IC chip 9 and an RFID antenna 10 and can perform wireless data communication.
The frequency band used for data communication is the UHF band (300 MHz to 3 GHz (preferably 860 to 960 MHz, more specifically 433 MHz, 900 MHz, 920 to 925 MHz, 950 to 956 MHz) and microwaves (1 to 30 GHz, Specifically, the IC is connected via the RFID antenna 10 by radio waves and electromagnetic action in a predetermined frequency band such as 2.45 GHz), HF band (3 MHz to 30 MHz (preferably 13.56 MHz)) or 135 kHz or less. Data necessary for the chip 9 is read and written (data communication) by radio.
However, the specific configurations of the IC chip 9 and the RFID antenna 10 are appropriate according to the radio waves used.

    The thermal printer 2 includes an RFID paper 1 supply unit 11, a transfer path 12, a position detection unit 13, a data reading / writing unit 14, a printing unit 15, and a control unit 16. It is loaded and transferred to the transfer path 12 to perform data communication with the RFID inlet 4 and printing on the sheet 6.

    The supply unit 11 holds the strip-shaped RFID sheet 1 in a roll shape, and feeds the RFID sheet 1 into the strip in the transfer path 12 so that the sheet can be transported.

    The position detection unit 13 can detect the position of the sheet body 3 in the transfer path 12, and is positioned upstream of the data reading / writing unit 14 in the transfer path 12, and detects any type of sensor, for example, a reflection type position detection. A sensor 17 is provided to detect the position detection mark 8 on the back side of the mount 5 in the RFID paper 1 so that the position of the paper piece 6 in the transfer path 12 in the thermal printer 31 can be detected.

    The data read / write unit 14 performs data communication with the RFID inlet 4, has a reader / writer antenna 18, and communicates with the RFID inlet 4 (IC chip 9, RFID antenna 10) of the label piece 6. Data communication, specifically, reading of data written in advance in the IC chip 9 and writing of necessary data into the IC chip 9 are enabled.

    The printing unit 15 is located on the downstream side of the data reading / writing unit 14 in the transfer path 12 and sequentially prints necessary contents on each sheet piece 6. The printing unit 15 includes a thermal head 19, a platen roller 20, and thermal transfer ink. The ribbon 21 has a supply shaft 22 and a take-up shaft 23. The RFID paper 1 is loaded into the thermal printer 2, and is sandwiched between the thermal head 19 and the platen roller 20, and the platen roller 20 rotates. Printing is performed on the RFID sheet 1 (the surface of the label piece 6) transferred through the transfer path 12 by driving at the portion of the heating element 19A of the thermal head 19.

    The control unit 16 controls the above-described units (the supply unit 11, the position detection unit 13, the data reading / writing unit 14, and the printing unit 15).

    Note that the thermal printer 2 has a peeling part for peeling the label piece 6 from the mount 5 or a cutting part for cutting the label piece 6 together with the mount 5 on the downstream side of the printing part 15 as needed. (Not shown).

FIG. 7 is an explanatory view showing the procedure of the process associated with the transfer of the RFID sheet 1. FIG. 7 (1) shows a state in which the position detection sensor 17 has detected the position detection mark 8, and FIG. ) Shows a state where the RFID antenna 10 is in an optimum position where data communication with the reader / writer antenna 18 is possible, and FIG. 7 (3) shows a cueing state where printing on the RFID paper 1 (label piece 6) can be started, FIG. 7 (4) shows a state where printing has been completed, and FIG. 7 (5) shows back-feeding the RFID sheet 1 to a position where the RFID antenna 10 can communicate with the reader / writer antenna 18 (reverse transfer in the upstream direction). Shows the state.
As shown in FIG. 7, the first distance D1 between the position detection sensor 17 and the reader / writer antenna 18, and the reader / writer antenna 18 and the thermal head 19 (the heating element 19A at the contact point between the thermal head 19 and the platen roller 20). Is set in advance as the thermal printer 2, and the position detection mark 8 and the RFID antenna 10 (the optimum sensitivity position thereof, for example, the central portion of the RFID antenna 10). ) Is also set when the RFID sheet 1 is created, and the position detection sensor 17 detects the position detection mark 8 of the label piece 6, whereby the label piece 6 in the transfer path 12 is detected. The data reading / writing unit 14 and the printing unit 15 perform processing.

That is, FIG. 8 is a flowchart of the process accompanying the transfer of the RFID paper 1. First, in step S 1, the transfer of the RFID paper 1 is started, and the position detection sensor 17 detects the position detection mark 8 (FIG. 7 ( 1)), the RFID sheet 1 (label piece) at a position (see FIG. 7 (2)) where data can be read from and written to the RFID sheet 1 (RFID inlet 4) by the data reading / writing unit 14 in step S2. Judge whether 6) has been reached.
Specifically, after the position detection sensor 17 detects the position detection mark 8, the RFID antenna 10 and the reader / writer antenna 18 and the data are transferred when the RFID sheet 1 is transferred by a necessary interval (D1-D3). It reaches the position where it can communicate.

    In step S3, when the RFID antenna 10 of the RFID inlet 4 is positioned in the data read / write unit 14, the transfer of the RFID paper 1 is stopped and data communication is performed. That is, data communication is performed between the data read / write unit 14 and the RFID inlet 4 to read and write data. In step S4, it is confirmed whether the data communication has been normally performed. In S5, warning sound or warning display and other necessary error processing are performed.

    If the data communication is normally performed in step S4, the RFID sheet 1 is further transferred downstream in the forward direction in the transfer path 12, and the leading end of the label piece 6 in the transfer direction at the fourth interval D4 (FIG. 7 (2)). The distance from the portion 6A to the heating element 19A of the thermal head 19 is transferred, and in step S6, it is determined whether the RFID sheet 1 has reached the print startable position (see FIG. 7 (3)) by the printing portion 15. In S7, necessary print processing (in the example shown, for example, the print content “ABCDE” and other barcodes and necessary information) is performed, and in step S8, it is determined whether printing has ended (see FIG. 7 (4)). .

    Further, in step S9, the entire RFID sheet 1 is back-fed upstream in the reverse direction, whereby the next label piece 6 is placed at a position where the RFID antenna 10 can communicate with the reader / writer antenna 18 (see FIG. 7 (5)). Then, data communication with the next label piece 6 and printing processing are performed in the same manner as described above.

However, in the conventional RFID paper 1 or thermal printer 2 as described above, the position where the label piece 6 can perform data communication in the vicinity of the reader / writer antenna 18 only by the position detection sensor 17 detecting the position of the label piece 6. Therefore, useless processing (that is, back-feed processing such as step S9 described above) must be performed for the alignment between the label piece 6 and the reader / writer antenna 18. There is a problem of not getting.
Therefore, there are problems that the transfer by the thermal printer 2 and other various controls are complicated, and the processing amount of the RFID paper 1 (label piece 6) per unit time is reduced.

    Of course, the procedure is not limited to the procedure shown in the flowchart of FIG. 8, the size of the label piece 6, the position of the RFID inlet 4 in the label piece 6, and the thermal head 19 and the platen roller 20 in the RFID inlet 4, particularly the IC chip 9 portion. Since the IC chip 9 may be damaged when the printing pressure is applied, depending on the printing layout on the label piece 6 or the like, it is necessary to perform the back feed process like step S9 before step S6 or step S7. There is also.

    The RFID paper is not limited to the label continuum as described above, but the same problems also occur in a tag continuum having a structure in which a tag piece (paper piece) is provided directly continuously without a mount or an adhesive layer. There is.

    The basic structure of the thermal printer 31 is the same as that of the thermal printer 1 (FIG. 3), but the relative position between the reader / writer antenna 18 of the data reading / writing unit 14 and the heating element 19A of the thermal head 19 of the printing unit. Is correlated with the site of the RFID antenna 10 in the RFID paper 30.
