Abstract

In a composite read / write device, the means for reading optical information and the means for reading / writing an RFID tag are completely different from each other, which increases the number of parts and increases the cost of the device and increases the housing of the device. There was a problem.
A combined read / write device comprises an antenna means in which a reflector as a means for reading optical information and an antenna as a means for reading and writing an RFID tag are integrated, and the antenna pattern is vapor-deposited. In addition, by using antenna means formed by forming an antenna pattern, it is possible to reduce the number of components, reduce the size of the housing, read and write the RFID tag with high accuracy, and read optical information.

Description

  The present invention relates to a composite reading / writing device having an optical information reading function and a wireless non-contact type reading / writing function.

In recent years, in addition to optical identification information such as barcodes, non-contact identification information using, for example, RFID tags has been given as identification information attached to products. Following this market trend, there is a composite reading / writing device having both an optical information reading function for reading optical identification information with a single reading device and a non-contact type reading / writing function for reading non-contact type identification information. It has been proposed (for example, see Patent Document 1).

  However, since the conventional composite reading / writing device is configured by simply combining the means for reading optical information and the means for reading / writing the RFID tag, which have completely different configurations, the entire device becomes larger and the number of parts is increased. The cost was also increased.

  An object of the present invention is to provide a composite read / write device in which a reflector used as a means for reading optical information and an antenna used as a means for reading and writing an RFID tag are integrated.

  In order to solve the above problems, a composite read / write device according to the present invention is a composite read / write device having an optical information reading function and a wireless non-contact type read / write function. A light source for irradiating light, a reflector for reflecting the reflected light from the optical information, an imaging means for imaging the reflected light reflected by the reflector, and a reflected light imaged by the imaging means Image recognition means for recognizing as an image, and an antenna for non-contact reading / writing is provided on the reflector.

  Further, the composite read / write device of the present invention is a composite read / write device having an optical information reading function and a wireless non-contact type read / write function, wherein the composite read / write device includes a housing. A light source that irradiates light to optical information, a reflector that is provided on the optical axis of reflected light from the optical information and close to the housing, and that changes the direction of the optical axis of the reflected light; An imaging means provided on the optical axis of the reflected light reflected by the reflector and imaging the reflected light; and an image recognition means for recognizing the reflected light imaged by the imaging means as an image; And an antenna for non-contact reading / writing is attached to the reflector provided close to the housing.

  Also, the composite read / write device of the present invention is such that the reflector and the antenna are integrated by forming an antenna pattern that acts as an antenna on the reflector by vapor deposition and a reflecting surface including the antenna pattern. It is.

  With the above configuration, the composite read / write device can form the antenna on a single substrate, and the manufacturing cost of the antenna can be reduced.

  Further, the composite read / write device of the present invention has a configuration in which a reflecting surface is formed by laminating a substrate on which an antenna pattern acting as an antenna is formed by vapor deposition, and the reflector and the antenna are integrated. .

  With the above configuration, the composite read / write device has a gap between the lines of the antenna pattern provided on one substrate. However, by changing the position of the antenna pattern on each substrate, By laminating so as to fill the gaps between each other, the reflectance as a reflector is improved, and the antenna pattern can also be used as a reflecting surface.

  As described above, the present invention reads and writes the reflector and the RFID tag that act as a means for reading the optical information in the composite reading / writing device having the optical information reading function and the wireless non-contact type reading / writing function. By integrating the antenna functioning as a means for reducing the number of parts, the size of the apparatus can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3.

(Embodiment 1)
FIG. 1 is a diagram showing a schematic cross section of the optical information 1, the RFID tag 6, and the composite read / write device 10.

  In FIG. 1, 1 is optical information such as a barcode, 2 is a light source that irradiates light to the optical information, 3 is a reflector that reflects reflected light from the optical information, and the reflector 3 includes an RFID tag. 6 and antenna means 8 for reading and writing information are integrated. 4 is an image forming means such as a lens for forming an image of the reflected light reflected by the reflector 3, 5 is an image recognizing means for recognizing the reflected light imaged by the image forming means 4 as an image, and 6 is An RFID tag 7 capable of exchanging information without contact, and a processing means 7 for reading and writing information to and from the RFID tag 6 through the antenna means 8.

  FIG. 2 is a block diagram showing an example in which the antenna means 8 is provided on the reflector 3.

  The antenna means 8 is provided integrally with the reflector 3 having a reflecting surface that reflects the reflected light from the optical information 1. The antenna means 8 has a function of an antenna for exchanging information with the RFID tag 6 wirelessly, and is formed as an antenna pattern in which a metal such as aluminum is deposited on the reflector 3.

  The reflector 3 provided with the antenna means 8 may have a structure in which a substrate provided with a reflecting surface and a substrate on which an antenna pattern is deposited are bonded to each other, or a reflecting surface is provided on one side of one substrate. 3 and an antenna pattern as the antenna means 8 may be deposited on the surface opposite to the reflecting surface of the reflector 3. And the reflector 3 can be made into a thin structure by providing the antenna means 8 and the reflecting surface on one substrate.

  Next, the operation of the composite reading / writing device 10 including the reflector 3 having the antenna means 8 will be described.

  When reading the information of the optical information 1 such as a barcode, the light emitted from the light source 2 is reflected by the optical information 1 and enters the composite reader 10, and this reflected light is reflected by the reflector 3 and is reflected in the optical path. Is changed, imaged by the imaging means 4 and read by the image recognition means 5. When reading information from the RFID tag 6 or writing information to the RFID tag 6, radio waves are emitted from the antenna means 8 integrated with the reflector 3 to communicate with the RFID tag 6 wirelessly. The means 7 reads information from the RFID tag 6 and writes information to the RFID tag 6.

  As described above, according to the present embodiment, the antenna unit 8 is integrated with the reflector 3 to read both the optical information 1 and the information of the RFID tag 6 with a small number of parts. Thus, the apparatus can be reduced in size and cost.

  In FIG. 1, the reflector 3 integrated with the antenna means 8 for reading and writing information with respect to the RFID tag 6 is on the optical axis of the reflected light from the optical information 1 and combined reading and writing. It is provided close to the housing 9 of the device 10. Thus, by providing the reflector 3 close to the housing 9, the reflector 3 can be shared for reading the optical information 1 and reading / writing the RFID tag 6, and the antenna means 8 further includes the antenna 9. Since the antenna means 8 can be used for communication at a short distance, the antenna means 8 can be used.

  In addition, as shown in FIG. 2, by forming the antenna means 8 integrated with the reflector 3 on the reflector 3 as a vapor deposition pattern, a more accurate antenna pattern can be realized. In addition, it is possible to form an inductance that matches the resonance frequency of the RFID tag 6 that is a communication target with higher accuracy, and it is possible to read and write the RFID tag 6 more excellently.

  The antenna means 8 provided on the reflector 3 and the reflecting surface may be provided on the opposite surface or on the same surface, and when provided on the same surface, a metal is vapor-deposited on one surface of the reflector 3. The antenna means 8 may be formed, and a reflective surface may be provided by evaporating metal on the same surface as the antenna means 8 so that the antenna means 8 is not electrically connected.

(Embodiment 2)
In the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The difference from the first embodiment is the configuration of the reflector 3.

  FIG. 3 shows the reflector 3 in the present embodiment. Reference numeral 11 denotes, for example, a transparent substrate capable of transmitting light. An antenna unit 8 is provided on the substrate 11, and the reflector 3 is formed by stacking a plurality of substrates, and an antenna pattern as the antenna unit 8 is formed. Is also used as a reflecting surface.

  Hereinafter, the configuration of the reflector 3 will be described in detail.

  When an antenna pattern in which a metal such as aluminum is vapor-deposited is provided as the antenna means 8 on the substrate 11, a gap is generated between the lines of the antenna pattern. When this antenna pattern is used as a reflecting surface, the area of the antenna pattern occupying the surface of the substrate 11 is small, and the light reflectance is low.

  Therefore, it is possible to increase the reflection surface by providing a plurality of substrates 11 with different positions for providing the antenna pattern, and laminating these substrates 11 so as to fill the gaps between them to form the reflector 3. Thus, the reflection efficiency can be improved.

  As described above, according to the present embodiment, the antenna pattern as the antenna means 8 can be used as a reflecting surface, and the reflectance can be improved.

  The composite read / write device of the present invention integrates a reflector that acts as a means for reading optical information and an antenna that acts as a means for reading and writing an RFID tag, thereby reducing the number of components and downsizing the device. This is possible and is industrially useful as a device for reading a plurality of record carriers.
