Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data carrier system comprising a responder (data carrier) and an interrogator (reader / writer), which is an interrogator for writing and reading data in the responder by non-contact wireless communication. The present invention relates to an antenna that constitutes a transceiver.

2. Description of the Related Art Entry / exit management to a specific room, logistics management, product inventory management, ski lift ticket, railway ticket, parking entry / exit management, expressway pass ticket, electronic money, etc. The interrogator / responder (reader / writer / data carrier) system is used in. The interrogator, that is, the reader / writer is mainly a fixed installation type, is connected to a host computer, and includes a control unit and an antenna unit. A transponder, that is, a data carrier is an IC (Integral Circuit) including a control unit, a storage unit, and an antenna unit, and has a card shape, a coin shape, or a box shape, which a person can carry, a product, an automobile, or the like. Mounted on and moved. The interrogator wirelessly sends an interrogation signal to the responder based on an instruction from the host computer. Upon receiving this, the responder reads the data requested by the inquiry signal from the storage unit and wirelessly sends the response signal. Alternatively, the data of the inquiry signal is stored in the storage unit.

For example, in room entrance / exit management, a person who is allowed to enter a room has an IC card transponder, and holds the IC card over an interrogator installed near an entrance door locked by an electronic lock. The interrogator constantly oscillates an interrogation radio wave signal. The IC card receives the interrogation radio wave signal, oscillates a response radio wave signal from the IC card, and the interrogator receives the response. The response signal is transferred from the interrogator to the host computer and evaluated there. The host computer issues an unlock signal for the electronic lock and stores the entry date and time in the memory together with the IC card number.

Recently, the interrogator has been downsized, and there is also a handy type interrogator, which is convenient because it can be held and used by a person. The host computer is connected wirelessly or by wire, and a handy type interrogator is manually brought close to the transponder (IC card, etc.) pasted on a large-scale product, etc., and the interrogator and the transponder are connected. It transmits and receives wireless radio signals. In contrast to the fixed installation type interrogator, the responder is moved closer to the responder, whereas the handy type interrogator is often moved to approach the responder.

[0005]

The handy type interrogator has the advantage that it can be carried in a wide area because it can be carried, but it has the drawback that one hand is blocked and work efficiency is reduced. In product delivery work, it is required to operate the interrogator while performing various tasks such as sorting and carrying the products. While sorting products, even if it is a handy type, holding the interrogator in hand and pointing it at the responder attached to the product deteriorates the work efficiency.

The present invention has been made to solve the above problems, and a wireless data carrier capable of extremely easily performing an operation for transmitting and receiving a radio wave signal while performing other work. It provides a transmitting and receiving antenna for the system.

[0007]

A transmitting / receiving antenna of a wireless data carrier system to which the present invention is applied, which has been made to achieve the above object, has an interrogator and a responder connected by wireless communication. In the transmission / reception antenna of the data carrier system, at least the antenna unit of the interrogator composed of the control unit and the antenna unit is integrated with the glove.

As shown in FIG. 1, an example of a transmitting / receiving antenna of this wireless data carrier system is that the control unit 12 of the interrogator 1 and the antenna unit 10 are separate bodies, and only the antenna unit 10 is the upper part of the glove 5. It is attached detachably to.

Another example of the transmitting / receiving antenna of this wireless data carrier system is, as shown in FIG. 5, that the control unit 12 and the antenna unit 10 of the interrogator 1 are integrated, and the interrogation including the antenna unit 10 is performed. The device 1 is detachably attached to the upper part of the glove 5.

The transmitting / receiving antenna of another embodiment of the wireless data carrier system to which the present invention is applied, which is also made to achieve the above object, is a data transmitting / receiving antenna in which data is connected between the interrogator and the responder by wireless communication. In the transmission / reception antenna of the carrier system, at least the antenna unit 10 of the interrogator composed of the control unit and the antenna unit is the wristband 9
(See FIG. 7).

The antenna section 10 can be formed on the insulator by wire, plating, conductive fiber, conductive ink or conductive paint. The insulator is preferably a flexible film, but a rigid substrate may be used. Also, a normal cloth (insulator) may be embroidered with conductive fibers.

According to this wireless data carrier system, the responder (data carrier) is provided with gloves or a wristband while performing various work while wearing gloves in which the antenna part of the interrogator (reader / writer) is integrated. A radio wave signal is transmitted and received between the interrogator and the responder simply by bringing the hand with the "" attached. Therefore, the operation of the data carrier system is instantaneously performed without almost stopping the progress of various works.
