- Patent Reference 1: Japanese Unexamined Patent Publication No. 2001-331768
- When information is written to the RF tag, there arises a problem that the information cannot be written well depending upon the difference in the frequency or the shape of the antenna, even if the position of the antenna in the label sheet and the position of the antenna of the reader/writer are the same.
- There is another problem that, if the length of the label sheet on the continuous sheet formed into a roll is short, the space between the RF tag on the label sheet and the RF tag provided on the adjacent label sheet becomes narrow. Specifically, data might be written on the RF tag on the label sheet that is not the target one, so that there is a problem that the type of the usable label sheet with the RF tag is naturally limited.
- In view of this, an object of the present invention is to provide a label printer, which performs printing to a label sheet provided with an IC tag and writes data to the IC tag, and which can cope with various types of label sheets.
- A label printer according to the present invention includes a print head that performs printing to a sheet provided with an IC chip; a transporting device that transports the sheet on a transporting path; an antenna that mediates data communication with the IC chip provided on the sheet transported on the transporting path; and a mechanism for adjusting a distance between the antenna and the transporting path.

Theink ribbon 106 is inserted between thethermal head 107 and thelabel sheet 102. Thethermal head 107 is in pressed contact with theplaten roller 107, whereby the ink (not shown) on theink ribbon 106 is transferred onto thelabel sheet 102 by the heat of thethermal head 107. - On the
label printer 101, an RF tag reader/writer (not shown) is mounted that writes or reads information to or from RF (Radio Frequency)tags FIG. 2 ) provided on thelabel sheet 102 as an IC chip. The RF tag reader/writer is provided to an antenna unit 121 (FIG. 4 ), and connected to anantenna 1 that transmits and receives electric wave to thetags FIG. 2 ). Theantenna unit 121 described above is arranged in the vicinity of the upstream side of thethermal head 107 in the transporting direction of thelabel sheet 102 and at the downstream side with respect to thetransport roller 104. -

antenna unit 121 will be explained.FIG. 4 is a longitudinal sectional view of theantenna unit 121,FIG. 5 is a perspective view showing a portion of theantenna unit 121, andFIG. 6 is a longitudinal sectional view of the same portion. - A mechanism for adjusting the distance between the
antenna 1 provided to theantenna unit 121 and thesheet transporting path 103 will be explained. Theantenna 1 has a structure in which asupport plate 1 a supports a coil (not shown). Thesupport plate 1 a of theantenna 1 is arranged below (at the side of the platen) thelabel sheet 102 that is guided and transported on thesheet transporting path 103, and formed long in the widthwise direction of thelabel sheet 102. The mechanism for adjusting the distance provided to theantenna unit 121 is composed of a mechanism for elevating thesupport plate 1 a of theantenna 1. Specifically,antenna fixing plates 2 are fixed to both ends of thesupport plate 1 a. Theantenna fixing plates 2 are configured such that two plates are opposite to each other with a gap capable of sandwiching thesupport plate 1 a of theantenna 1, and have a slit shape in which the side opposite to the side of sandwiching thesupport plate 1 a is closed. Since theantenna fixing plates 2 having the slit shape hold both ends of thesupport plate 1 a in the widthwise direction of thelabel sheet 102, theantenna fixing plates 2 are fixed to thesupport plate 1 a. Theantenna unit 121 has aframe 5 that forms aspace 5 c between anupper member 5 a and alower member 5 b. Further, anopening 5 d is formed on theupper member 5 a and thelower member 5 b of theframe 5 as shown inFIG. 7 .

This risingmember 5 e is provided in order to prevent data from being written again after the printing onto the label sheet on which data has already been written. - A pair of
movable screws 3 is attached to theframe 5 so as to rotate about the axis of themovable screw 3, and thesupport plate 1 a of theantenna 1 is attached to themovable screws 3. Specifically, a pair ofscrew holes 1 b is formed to thesupport plate 1 a of theantenna 1 and theantenna fixing plates 2, and themovable screws 3 are screwed to thescrew holes 1 b. Themovable screw 3 is rotatably provided to theframe 5 in such a manner that themovable screw 3 penetrates thelower member 5 b of theframe 5 from below, and is prevented by a screw come-off preventingmember 3 a from coming off, and the leading end thereof is fitted to aboss 4 a provided at theupper member 5 a of theframe 5. An E-ring that can detachably be provided to themovable screw 3 is employed as the screw come-off preventingmember 3 a, for example. Therefore, in the example of the mechanism for adjusting the distance, by rotating themovable screws 3, the position of theantenna fixing plates 2 can be vertically moved by the screw action. Specifically, since the position of theantenna 1 changes to thesheet transporting path 103, the distance between theantenna 1 and thelabel sheet 102 can be changed. - With this mechanism, the distance between the
antenna 1 and thelabel sheet 102 a (or 102 b), which is drawn from the rolled state and transported, can be adjusted depending upon the type of thelabel sheets tags antenna 1 is attached to the position where data is always correctly written in the frequency of one district, the data might not correctly be written when the data is written to the tag having a frequency according to the other district. The frequency in which the data cannot be written is unallowable degree as an actual product. However, according to one embodiment for solving this problem, information can correctly be written to thetags label sheets tags -

Thepartitioning plates holes holes partitioning plates antenna 1 and thelabel sheet sheet transporting path 103, and serves as a shielding member that blocks electric wave transmitted from theantenna 1 from reaching the position other than the target direction so as to limit the range of writing the information to thetags antenna 1. - Specifically, only the electric wave passing through the through-
holes tags label sheet - The
partitioning plate label sheet 102 a and thelabel sheet 102 b is used, whereby the narrow through-hole 8 a or wide through-hole 9 a can be selected, and hence, optimum information writing can be performed according to the type of thelabel sheet 102. - In one embodiment described above, the
antenna fixing plates 2 are moved vertically by the screw action by rotating the antennamovable screws 3, as the structure for changing the position of theantenna 1. However, the antennamovable screws 3 may not be used, and a detachable structure for screwing theantenna fixing plates 2 for fixation at plural positions including the position relatively close to the transportedlabel sheet 102 and the position relatively far from the transportedlabel sheet 102 may be provided, whereby theantenna 1 is fixed to the position relatively close to the transported label sheet or the position relatively far from the transportedlabel sheet 102. - In the case of the aforesaid UHF band, the
antenna 1 is attached close to thelower member 5 b in the product for the United States, while theantenna 1 is attached close to theupper member 5 a in the product for Europe. The optimum space between the attachment position of theantenna 1 in the product for the United States and the attachment position of theantenna 1 in the product for Europe is about 5 mm. Specifically, theantenna 1 is attached to the close position generally in contact with thesheet transporting path 103 in the product for Europe, while theantenna 1 is attached to the position apart from thesheet transporting path 103 by about 5 mm in the product for the United States. - The shape of the
antenna 1 is not specifically described in the present application, but the shape of theantenna 1 varies since the frequency to be handled is different. Therefore, in the present embodiment, the attachment position of theantenna 1 is determined according to the shape of theantenna 1.
