[Technical field to which the invention belongs]

 The present invention relates to a non-contact data carrier recognition system capable of performing non-contact communication between a transponder and an interrogator mounted on a metal surface as a non-contact data carrier, and particularly to a non-contact data carrier mounting device. About.

[0002]

[Prior art]

 In recent years, as a system for automatically reading and identifying information given to articles, it can handle a greater amount of information instead of the barcode method known from the past, and is environmentally friendly. In addition, a non-contact data carrier recognition system called a data carrier system capable of remote reading has been actively developed.

This non-contact data carrier system includes a transponder called a non-contact data carrier attached to an article and an interrogator connected to a host. It is characterized in that communication is performed in a non-contact manner via transmission media such as magnetism, induction electromagnetic field, and microwaves (radio waves). The information transmission method of the non-contact data carrier recognition system includes an electromagnetic coupling method, an electromagnetic induction method, a microwave method, an optical communication method, and the like. Among these methods, those using the electromagnetic coupling method or the electromagnetic induction method can use the energy of the transmission signal from the interrogator as the driving power for the transponder.

FIG. 4 shows an overall configuration of a contactless data carrier system. As shown in the figure, the contactless data carrier system includes an interrogator 10 and a transponder 20 (contactless data carrier).

The interrogator 10 includes a main controller 11 that controls the entire interrogator 10, an interface 11 that controls input and output of data with the host device, tag information received from the non-contact data carrier 20, and the like. A storage unit 13 such as a readable / writable RAM for accumulating data, a signal conversion unit 14 for converting transmission information from a parallel signal to a serial signal, and converting a reception signal from the transponder 20 from a serial signal to a parallel signal. A modulating unit 15 for modulating a transmission signal into a signal for transmission by, for example, an ASK (Amplitude Shift Keying) method, an FSK (Frequency Shift Keying) method, a demodulation unit 16 for demodulating a received signal, a transmitting antenna 17, The receiving antenna 18 is provided.

The transponder (non-contact data carrier) 20 includes a main control unit 21 that performs overall control of the non-contact data carrier 20, a storage unit 22 such as an EEPROM that stores tag information and does not require a power backup, and A signal converter 23 for converting transmission information from a digital signal to an analog signal, and converting a reception signal from the interrogator 10 from an analog signal to a digital signal; and a transmission signal for transmitting a transmission signal in an ASK system, an FSK system, or the like. , A demodulation unit 25 for demodulating a received signal, a transmission antenna 26, and a reception antenna 27.

A basic communication procedure of this contactless data carrier system is as follows. First, the interrogator 10 issues an interrogation signal for reading tag information from the contactless data carrier 20. The non-contact data carrier 20 receives the inquiry signal when it enters the receivable range, and transmits the tag information stored in the storage unit 22 as a response signal. The interrogator 10 receives and decodes this response signal and sends it to the host device as tag identification information.

FIG. 5 is a schematic view of the arrangement of internal components of the contactless data carrier 20, FIG. 6 is a plan view showing the configuration of such a transponder 20, and FIG. 7 shows the configuration of the transponder 20. It is a sectional view. As described above, the transponder 20 (non-contact data carrier) is mainly composed of the antenna 2 and the circuit component 1 for transmitting and receiving signals to and from the interrogator 10, and in consideration of durability and environmental resistance, Usually, it has a structure in which the internal components 3 such as the antenna 2 and the circuit component 1 are hermetically sealed with resin or the like. As the antenna 2, a coil formed of copper copper wire is frequently used in terms of price and productivity, and as the circuit component 1, for example, a copper circuit pattern and a terminal portion are formed on the surface of an epoxy substrate 1 a. In general, the antenna 2 is wire-bonded. The antenna 2 is usually formed of a copper wire having an outer diameter of 30 to 200 μm. The two end wires (conductor portions) 1 c of the coil are connected to the terminals of the circuit component 1 by welding or soldering. As a resin material for hermetically sealing these internal components 3, thermoplastic resins such as vinyl chloride resin, polyethylene terephthalate resin, acrylonitrile-butadiene-styrene copolymer resin, or epoxy resin, phenol resin, Thermosetting resins such as silicone resins are used.

The transponder 20 is generally sealed by sandwiching the coil and the circuit component 1 between two resin sheets made of a thermoplastic resin or a thermosetting resin. That is, the resin sheets are overlapped from above and below the coil and the circuit component 1, and the internal component 3 is sandwiched between the two resin sheets.

Next, the resin sheet sandwiching the internal component 3 is further sandwiched between two stainless plates, and the coil and the circuit component 1 are hermetically sealed by the resin layer 4 by hot pressing from both sides of the stainless plate. The transponder 20 is manufactured by stopping and then punching it to a predetermined size.

[0011]

[Problems to be solved by the invention]

 In the non-contact data carrier recognition system of the electromagnetic coupling type or the electromagnetic induction type, if the transponder 20 (non-contact data carrier) is closely mounted on a metal surface, the communication distance is greatly reduced or communication becomes impossible. For this reason, when the transponder 20 (non-contact data carrier) is mounted on a metal surface, a method of attaching the transponder 20 with a seal or the like interposed therebetween or directly embedding it is adopted. However, the above method of interposing a seal is easy to remove, but does not provide a sufficient communication distance with the interrogator antenna. In addition, with the direct embedding method, removal is difficult and a sufficient communication distance cannot be obtained.

Further, depending on the product to be actually used, when the period during which the transponder 20 (contactless data carrier) is required is limited, or when the transponder 20 is not disposable but needs to be collected, It is necessary to simplify the removal of the transponder 20.

[0013] The present invention is intended to solve the above-described problem. When a non-contact data carrier is mounted on a metal surface, the communication distance with the interrogator antenna, the distance with the metal surface, and the easy removal are ensured. The purpose is to achieve the goal.
