Description

  The present invention relates to a portable data reader capable of reading information data stored in an IC tag in a contactless manner and writing information data in an IC tag in a contactless manner.

  In recent years, in order to manage information data related to articles, IC tags equipped with extremely small IC chips and antennas have been used. The information data stored in the IC tag can be read in a non-contact manner by a portable data reading device including a reading device main body and an antenna provided with a display unit, an operation unit, a transmission / reception unit, a control processing unit, and the like. It is like that.

  That is, the IC tag is fixed to the surface of the article or its packaging container, the antenna of the portable data reader is brought close to the surface of the IC tag, and the electromagnetic wave signal transmitted from the IC tag is captured by the antenna. The information data stored in is read. Information data is displayed as characters, numbers, symbols, and the like on the display unit of the reader main body including a liquid crystal display.

  Here, in order to reliably read the information data stored in the IC tag, the antenna of the portable data reader is brought close to the surface of the IC tag as much as possible, and the angle of inclination of the antenna with respect to the surface of the IC tag is set to a predetermined value or less. There is a need to.

  When the IC tag is fixed to a movable small article or packaging container, the position of the antenna of the portable data reader can be determined by holding the article or packaging container with one hand or placing it in an appropriate place. In addition, the inclination angle can be set appropriately.

However, when the IC tag is fixed to an immovable large article or packaging container, the article or packaging container cannot be gripped or placed at an appropriate place. The position and the inclination angle cannot be set appropriately.
Therefore, the information data stored in the IC tag cannot be read reliably, or the stored information data may be read erroneously.

  In order to solve this problem, as shown in FIG. 8, a portable data reader comprising an antenna 103 made of a flexible metal wire and equipped with a storage pipe 104 for housing the antenna 103 in the reader main body 102. 101 is proposed (see Patent Document 1).

  According to the portable data reader 101, the antenna 103 is extended from the storage pipe 104 and bent at an appropriate inclination angle, thereby bringing the antenna 103 close to the surface of the IC tag as much as possible, and with respect to the surface of the IC tag. Since the antenna 103 can be set at a predetermined inclination angle, the information data stored in the IC tag can be reliably read without error.

Japanese Patent Publication No. 2004-139608

However, in the portable data reading apparatus 101 disclosed in Patent Document 1, the operator pulls the antenna 103 made of a metal wire with a finger to extend from the storage pipe 104 and pushes it into the storage pipe 104. It had to be stored, was quite cumbersome and took time.
In particular, it is not easy to completely return the antenna 103 made of a metal wire once bent, and it is troublesome to store the antenna 103 in the storage pipe 104.

  In addition, the antenna 103 made of a flexible metal wire is easy to bend and at the same time is easily deformed. By repeating the bending, the antenna 103 cannot be completely restored to its original shape or is made of a metal wire, so that the mechanical strength is weak. There is also a problem with durability, and there is a risk of damage within a relatively short period of time.

  The present invention has been made in view of such conventional problems, and the object of the present invention is to allow the antenna to be easily and quickly extended from the reader body and to be accommodated. It is an object of the present invention to provide a portable data reader which does not easily become permanently deformed, has no problem in mechanical strength and durability, and is not easily damaged even after long-term use.

  In order to achieve the above object, the present invention provides a display unit for displaying an operation state, an operation command, information data, etc., an operation unit for inputting the operation command, information data, etc., and an information data signal by receiving an electromagnetic wave signal. A transmission / reception unit that converts a command signal and an information data signal into an electromagnetic wave signal, and an operation command and information data input from the operation unit, and reads the information data signal received by the transmission / reception unit And a control processing unit that transmits an operation command signal and an information data signal to the transmission / reception unit, and outputs and displays an operation state, an operation command, information data, and the like on the display unit, and an IC tag In a portable data reader comprising an antenna that captures a transmitted electromagnetic wave signal to acquire information data, and transmits an electromagnetic wave signal to impart information data to an IC tag. , Characterized in that the antenna and the metal wire coated with synthetic resin and formed into thin plate.

  Furthermore, an antenna housing portion is disposed on the back surface of the reader main body, and the antenna is slidable and can be pulled out from the antenna housing portion.

  Hereinafter, a preferred embodiment of a portable data reader of the present invention will be described with reference to the drawings.

  A portable data reader 1 according to the present invention includes a reader main body 2 and an antenna 3 as shown in FIGS.

  As shown in FIGS. 1 and 2, the reading device main body 2 has a display unit 4 and an operation unit 5 on the front side, a transmission / reception unit 6 and a control processing unit 7 inside, and an antenna storage unit 8 on the back side. It is set up.

  The display unit 4 is composed of a liquid crystal display disposed on the surface portion of the housing 9, and displays the operation state of the reader body 2, operation commands, information data stored in the IC tag, etc. by letters, numbers, symbols, etc. indicate.

  The operation unit 5 includes a power button 51, characters, numbers and symbols button 52, a data reading button 53, an operation mode button 54, a cursor movement button 55, and the like disposed on the surface of the housing 9. 2. Input various operation commands, information data, etc.

  The transmission / reception unit 6 is composed of a transmission / reception circuit disposed inside the housing 9, receives an electromagnetic wave signal captured by the antenna 3 and converts it appropriately into an information data signal, and various command signals and information data. The signal is converted into an electromagnetic wave signal and transmitted to the antenna 3.

  The control processing unit 7 is composed of a central processing unit (CPU), a control processing circuit, and the like disposed in the housing 9, and processes and transmits various operation commands, information data, and the like input from the operation unit 5. The information data signal received by the receiving unit 6 is read, and various operation command signals and information data signals are transmitted to the transmission receiving unit 6, and the operation state, operation command, information data, and the like are output and displayed on the display unit 4.

As shown in FIG. 2, the antenna storage portion 8 is formed so as to be raised on the back surface portion of the housing 9 so that the antenna 3 can be retracted.
An opening 81 is formed at one end of the antenna housing 8, and a guide groove 82 is formed in the direction in which the antenna 3 is pulled out.

As shown in FIGS. 5 and 6, the antenna 3 is formed by coating a metal wire 31 having a U-shaped tip portion with a synthetic resin 32 and molding the tip portion into a thin plate material having an arc shape, The electromagnetic wave signal transmitted from the IC tag is captured to acquire information data, and the electromagnetic wave signal is transmitted to impart information data to the IC tag.
The base end portion of the antenna 3 is sandwiched between the antenna supports 10a and 10b, and the gripping member 11 is screwed.

  Then, as shown in FIGS. 2 and 4, the base end portion of the antenna 3 and the antenna supports 10 a and 10 b are positioned in the antenna housing portion 8, and the gripping member 11 protrudes from the guide groove portion 92 of the antenna housing portion 8. Thus, the antenna 3 can be pulled out by making the antenna supports 10a and 10b slidable in the antenna housing portion 8.

  Therefore, if the operator presses the finger 11 with his / her finger and moves the gripping member 11 to one end, the tip of the antenna 3 protrudes from the opening 91 as shown in FIGS. The antenna 3 can be housed in the antenna housing portion 8 as shown in FIGS. 1 and 3 if it can be pulled out from the housing portion 8 and the gripping member 11 is moved to the other end portion.

  According to the portable data reader 1 of the present invention, as shown in FIG. 7, an operator presses with a finger to move the gripping member 11 to one end, and slides the antenna 3 from the antenna housing 8. By bringing the tip of the antenna 3 as close as possible to the IC tag A fixed to the surface of the drawer, article or packaging container, the information data stored in the IC tag A can be reliably read without error.

  In particular, as shown in FIG. 7, when a step or a protrusion is formed in the vicinity of the position where the IC tag A is fixed, like the conventional portable data reader 101, the antenna 103 made of a metal wire one by one. Since it is not necessary to extend the storage pipe 104 from the storage pipe 104 and set its length and inclination angle, the information data can be read easily.

  Further, since the antenna 3 can be slid by pressing and moving the gripping member 11 with a finger, the antenna 3 can be easily pulled out from the antenna housing portion 8 and can be easily put into the antenna housing portion 8. The antenna 3 can be pulled out and stored in a very simple manner and does not take much time.

  Further, the antenna 3 is formed by forming a metal wire 31 into a thin plate coated with a synthetic resin 32. Therefore, compared with the antenna 103 made of a conventional metal wire, the antenna 3 has a much higher restoring force and can easily be permanently deformed. In addition, the mechanical strength and durability are remarkably excellent, and it is not easily damaged even after long-term use.

  Further, when the antenna is housed, the antenna 3 can be completely housed in the antenna housing portion 8, so that the antenna 3 may be deformed even if the portable data reader 1 is accidentally dropped or collided. No damage or damage.
