Description

  The present invention relates to a tag label producing device for producing a RFID label including a RFID circuit element capable of reading or writing RFID tag information from outside via wireless communication, and a tag label producing device cartridge used therefor.

  There is known an RFID (Radio Frequency Identification) system that reads / writes information in a non-contact manner between a small wireless tag and a wireless tag communication device (reader / writer). The wireless tag circuit element provided in the wireless tag label includes an IC circuit unit that stores predetermined wireless tag information and an antenna that is connected to the IC circuit unit and transmits and receives information. Even when the RFID label is dirty or placed at an invisible position, the reader / writer can access (read / write information) the RFID tag information in the IC circuit section. There are already practical applications in various fields such as product management and inspection processes.

  Usually, when preparing such a RFID label, each RFID circuit element is placed in the longitudinal direction of the tape by feeding a strip-like tag tape provided with RFID circuit elements in the longitudinal direction of the tape at predetermined intervals from the tag tape roll. When this is carried, predetermined RFID tag information generated on the tag label producing device side is transmitted to the antenna of each RFID tag circuit element via the antenna on the device side. Write sequentially to the IC circuit connected to the antenna. The RFID circuit element in which the RFID tag information has been written is then conveyed downstream in the conveying direction and cut into a label having a predetermined length, thereby completing the RFID tag label.

  Here, regarding the writing of information into the RFID tag circuit element as described above, for example, a method described in Patent Document 1 is known as a method related to communication control during writing. In this prior art, signal transmission is performed wirelessly from the reader / writer side to the RFID circuit element conveyed in the direction orthogonal to the direction of the antenna of the reader / writer. And the transmission output at the time of the said signal transmission is adjusted according to whether the communication error has arisen at that time.

  As described above, in the tag label producing apparatus, information is transmitted / received by radio communication with the RFID circuit element when producing the RFID label. However, in the case where various wireless communication devices such as other wireless tag communication devices, mobile phones, and OA devices using a wireless LAN are used in the vicinity of the tag label producing device, the wireless tag circuit described above is used. There is a possibility of causing information transmission and reception and radio wave interference with the element. In such a case, if the tag label producing device is operated without knowing it, and the RFID label is created, the communication with the RFID circuit element becomes unstable, and the RFID label is created without normal transmission / reception of information ( = It may be a defective product). The prior art described above improves the certainty of communication with the RFID circuit element by adjusting the transmission output. However, no particular consideration is given to the radio wave interference due to the surrounding radio wave environment. For this reason, it has been difficult to improve the quality and reliability of the RFID label produced.

  An object of the present invention is to provide a tag label producing apparatus capable of improving the quality and reliability of a produced RFID label.

  In order to achieve the above object, a first invention is a tag in which an RFID circuit element for producing a label having an IC circuit section for storing information and a tag antenna for transmitting and receiving information is arranged in an outer section. A conveying means for conveying a medium; a label producing antenna that transmits and receives information to and from the label producing RFID circuit element of the tag medium through wireless communication using a predetermined first frequency; and A noise detection unit that detects disturbance noise with respect to a frequency and a signal output unit that outputs a control signal corresponding to the noise detection unit when the noise detection unit detects the disturbance noise.

  In the first invention of the present application, the tag medium is conveyed by the conveying means. Information is transmitted / received to / from the RFID tag circuit element provided in the tag medium by wireless communication using the first frequency with the label producing antenna. In this way, a RFID label is created using a tag medium including a RFID circuit element that has completed information transmission and reception. Here, in the first invention of the present application, noise detection means is provided to detect whether there is disturbance noise with respect to the first frequency used at the time of label production. When disturbance noise is detected, the signal output means outputs a control signal corresponding to the disturbance detection. Accordingly, it is possible to take measures such as notifying the operator that there is a disturbance based on the control signal, or switching to use a different frequency from the first frequency. Therefore, it is possible to prevent a defective tag label from being erroneously created in an unstable communication state with disturbance noise. As a result, it is possible to improve the quality and reliability of the RFID label produced.

A second invention has signal input means for inputting a tag label production instruction signal in the first invention, and the noise detection means receives the disturbance noise when the tag label production instruction signal is inputted by the signal input means. The signal output means outputs the control signal before starting the production of the tag label corresponding to the tag label production instruction signal when the noise detection means detects disturbance noise. To do.

  In the second invention of the present application, when the operator performs an operation intended to produce a tag label, a tag label production instruction signal corresponding to the operation is inputted by the signal input means. As a result, the noise detection means starts detecting whether or not there is disturbance noise prior to the creation of the tag label. When disturbance noise is detected, the signal output means outputs a control signal before starting the production of the tag label. As a result, when the operator intends to start the production of the tag label, before the actual production of the label, the operator is notified that there is a disturbance based on the control signal, or the first frequency and It is possible to take measures such as switching to use a different frequency.

  In a third aspect of the present invention based on the second aspect, the signal output means detects the disturbance noise for the first frequency by the noise detection means, and does not start the production of the tag label as the control signal. A noise notification signal is output.

  Notifying the operator of the fact that tag label creation work is not started when disturbance noise occurs, so that the operator can be sure that the radio wave environment is not good, and the creation of defective labels can be prevented reliably. .

  In a fourth aspect based on the third aspect, the signal input means inputs the tag label creation instruction signal from an operation terminal outside the apparatus, and the signal output means outputs the noise notification signal to the operation terminal. It is characterized by.

  As a result, when the operator gives an instruction to start tag label production via an external operation terminal, the operator on the operation terminal side is surely notified and recognized that the radio wave environment is not good due to the generation of disturbance noise. be able to.

  A fifth invention is characterized in that, in the third invention, there is provided a notifying means for performing visual notification in accordance with the noise notification signal from the signal output means.

  The visual notification of the notification means can make the operator surely recognize that the disturbance noise is generated.

  In a sixth aspect of the present invention, in any one of the third to fifth aspects of the present invention, after the noise notification signal is output by the signal output unit, the noise detection unit no longer detects disturbance noise for the first frequency. It has a cooperation control means which controls the said conveyance means and the said antenna for label production so that label production corresponding to the said tag label production instruction signal may be started.

  As a result, even if the creation of the tag label is not started due to the occurrence of disturbance noise at the beginning, if the disturbance noise disappears thereafter, the tag label creation is started quickly, and the RFID label is surely attached. Can be created.

  In a seventh aspect based on the second aspect, a first command generation for generating a first command signal using the first frequency to be transmitted to the label producing RFID circuit element through the label producing antenna. And second command generation means for generating a second command signal using a second frequency different from the first frequency for transmitting to the label producing RFID circuit element via the label producing antenna. And frequency switching means for selectively outputting either the first command signal or the second command signal to the label producing antenna, wherein the signal output means is the noise detection means and the first When disturbance noise with respect to the frequency is detected, a frequency switching signal as the control signal is output, and the frequency switching means responds to the frequency switching signal. And, characterized in that to output said second command signal to the label producing antenna.

  In the seventh invention of the present application, the first command signal and the second command signal using the first frequency can be selectively outputted to the label producing antenna, and these are switched to switch between the label producing RFID circuit element and the radio. Communication can be performed. When the noise detection means detects disturbance noise with respect to the first frequency, the frequency switching means switches the use frequency and communicates with the RFID tag circuit element for label creation using the second command signal using the second frequency. I do. By using the second frequency, it is possible to perform stable and good communication with the label producing RFID circuit element without being adversely affected by disturbance noise with respect to the first frequency. As a result, it is possible to prevent the production of a defective tag label and improve the quality and reliability of the RFID tag label.

  An eighth invention is characterized in that, in any one of the second to seventh inventions, a frequency in the UHF band is used as the first frequency or the second frequency.

  When the UHF band frequency is used, the communication distance is relatively longer than when the HF band frequency is used, and therefore, the tag label is easily affected by the surrounding radio wave environment. Therefore, various measures based on the control signal corresponding to the detection of disturbance noise as described above are more effective.

  According to a ninth invention, in any one of the second to eighth inventions, the noise detecting means compares the reception intensity at the first frequency received via the label producing antenna with a predetermined threshold value. It is a 1st detection circuit provided with the receiving intensity determination means, It is characterized by the above-mentioned.

  Of the surrounding radio waves received via the label producing antenna, the reception intensity determination means of the first detection circuit determines whether or not the reception intensity at the first frequency is greater than or equal to a threshold value. As a result, when the frequency is equal to or greater than the threshold value, it is possible to consider that there is a radio wave device using a frequency close to the first frequency (a state in which tag label creation should not be performed).

  A tenth aspect of the present invention is the information acquisition RFID tag element according to any one of the second to eighth aspects, comprising an IC circuit unit for storing information and a tag antenna for transmitting and receiving information, An information acquisition antenna that transmits and receives information by wireless communication, and the noise detection means uses the reception intensity at the first frequency received via the information acquisition antenna as a predetermined threshold value. It is a 2nd detection circuit provided with the receiving strength determination means to compare.

  Of the surrounding radio waves received via the information acquisition antenna, the reception intensity determination means of the second detection circuit determines whether the reception intensity at the first frequency is equal to or higher than a threshold value. As a result, when the frequency is equal to or greater than the threshold value, it is possible to consider that there is a radio wave device using a frequency close to the first frequency (a state in which tag label creation should not be performed). In addition, by performing noise detection based on reception by an information acquisition antenna different from the label creation antenna, the noise detection function and the original label creation communication function are distinguished and shared by separate antennas. be able to.

  In an eleventh aspect according to any one of the tenth aspects, the signal output means outputs, as the noise notification signal, a shielding warning signal for warning a state of insufficient shielding of the outer portion. .

  When noise is detected from radio waves received via the information acquisition antenna provided in the outer part, for example, there is an opening that should not be originally in a part of the outer part due to forgetting to close the door or closing the lid. There is a possibility that it is generated or the shielding at the opening part originally provided in the outer part such as the tag medium discharge port is insufficient. Accordingly, in the eleventh aspect of the present invention, when disturbance noise is detected by the noise detection means, a shielding warning signal indicating that the shielding is insufficient is output. Thereby, the operator can appropriately take countermeasures for improving the shielding according to the above.

  According to the present invention, the quality and reliability of a produced RFID label can be improved.

  The RAM 117 is provided with a text memory 117A, a print buffer 117B, a parameter storage area 117E, and the like. The text memory 117A stores document data input from the PC 118. In the print buffer 117B, a dot pattern for printing such as a plurality of characters and symbols, the number of applied pulses that is the amount of energy for forming each dot, and the like are stored as dot pattern data. The print head 23 is stored in the print buffer 117B. Dot printing is performed according to the existing dot pattern data. The parameter storage area 117E stores various calculation data, tag identification information (tag ID) of the information acquisition RFID circuit element To (described above) that has been read (acquired), and the like.

  The transmission circuit 306 and the reception circuit 307 are connected to the loop antennas LC1 and LC2 via the antenna duplexer 240 (transmission / reception separator) and the changeover switch 86. Based on the control signal from the control circuit 110, the changeover switch 86 switches the antenna duplexer 240 to connect to the label producing loop antenna LC1 or the information obtaining loop antenna LC2. Specifically, the control circuit 110 first connects the antenna duplexer 240 and the information acquisition loop antenna LC2 when noise is detected, and then connects the antenna duplexer 240 and the label creation loop antenna LC1 when creating a label. Further, the changeover switch 86 is controlled (refer to the flow of FIGS. 12 and 14 described later).

  In such a control system having the control circuit 110 as the core, when character data or the like is input via the PC 118, the text (document data) is sequentially stored in the text memory 117A, and the print head 23 is driven by the drive circuit. 120, each of the heat generating elements is selectively driven to generate heat corresponding to the print dots for one line, and the dot pattern data stored in the print buffer 117B is printed, and in synchronization with this, for carrying The motor 119 performs tape transport control via the drive circuit 121. In addition, the transmission circuit 306 performs carrier wave modulation control based on the control signal from the control circuit 110 and outputs an interrogation wave, and the reception circuit 307 processes the demodulated signal based on the control signal from the control circuit 110.

The reception circuit 307 for inputting the response wave from the RFID circuit element To received by the antenna LC and the antenna duplexer 240 are configured.

  In response to a control signal (carrier wave generation command signal) from the control circuit 110, the transmission circuit 306 transmits an interrogation wave for accessing (reading or writing) the RFID tag information of the IC circuit unit 151 of the RFID circuit element To. In a block to be generated, a crystal resonator 335 that generates a carrier wave of an interrogation wave, a PLL (Phase Locked Loop) 336 that generates a signal of a predetermined frequency under the control of the control circuit 110, a VCO (Voltage Controlled Oscillator) 337, A transmission multiplier circuit 338 that modulates the generated carrier wave based on the signal supplied from the control circuit 110 (in this example, amplitude modulation based on the “TX_ASK” signal from the control circuit 110). An amplification factor variable amplifier or the like may be used), and the modulation wave modulated by the transmission multiplication circuit 338 And a transmission amplifier 339 to determine amplifying the amplification factor by the "TX_PWR" signal from 10. The generated carrier wave preferably uses a UHF band frequency (for example, a very high frequency wave of 2.45 GHz, hereinafter referred to as “first frequency”). The output of the transmission amplifier 339 (that is, the first command signal using the first frequency) is transmitted to the label producing loop antenna LC1 via the antenna duplexer 240, and is transmitted to the IC circuit unit 151 of the RFID circuit element To. Supplied. The interrogation wave is not limited to the signal (modulation wave) modulated as described above, and may be only a carrier wave (the same applies to modified examples described later).

  The receiving circuit 307 multiplies the reflected wave from the RFID circuit element To received by the label creating loop antenna LC1 (or the information acquiring loop antenna LC2) by the generated carrier wave and demodulates the received first receiving circuit 307. A multiplier circuit 340, a first bandpass filter 341 for extracting only a signal in a necessary band from the output of the reception first multiplier circuit 340, and a reception first amplifier 343 for amplifying the output of the first bandpass filter 341 And a first limiter 342 for further amplifying the output of the reception first amplifier 43 and converting it to a digital signal, a reflected wave from the RFID circuit element To received by the antennas LC1 and LC2, and the generated wave after the generation.

The signal “RXS-I” output from the first limiter 342 and the signal “RXS-Q” output from the second limiter 346 are input to the control circuit 110 and processed.

  The outputs of the reception first amplifier 343 and the reception second amplifier 347 are also input to an RSSI (Received Signal Strength Indicator) circuit 348, and a signal “RSSI” indicating the strength of these signals is input to the control circuit 110. . As a result, the tag label producing apparatus 1 can detect the signal intensity from the RFID circuit element To during communication with the RFID circuit element To.

  The receiving circuit 307 includes a detection circuit 350 (second detection circuit, noise detection means) that detects disturbance noise with respect to the first frequency. When producing the RFID label T, first the changeover switch 86 is switched to the label producing loop antenna LC1 side (to communicate with the label producing RFID circuit element To using the first frequency). 86 is switched to the information acquisition loop antenna LC2. Then, the noise signal received by the information acquisition loop antenna LC2 is input to a reception strength determination means (not shown) provided in the detection circuit 350, and it is determined whether or not the reception strength is equal to or greater than a threshold value. Thus, the presence or absence of disturbance noise with respect to the first frequency is detected. Accordingly, when the frequency is equal to or greater than the threshold value, it is considered that there is a radio wave device using a frequency close to the first frequency, that is, a state in which tag label creation cannot be performed.

  At this time, as shown in the figure, the detection circuit 350 (in this example) is upstream of the first and second bandpass filters 341 and 345 along the flow of the received signal (in other words, the RFID circuit element To Before being narrowed down to a communication frequency band (= first frequency) used in communication with Therefore, it is possible not only to detect disturbance noise with respect to the first frequency but also to detect noise (interference wave) within a wider band than the first frequency. In this case, it is possible to more reliably prevent adverse effects on tag label production due to disturbance.

  In the above description, the changeover switch 86 is switched to the information acquisition loop antenna LC2 side, and the disturbance noise signal is detected by the detection circuit 350 from the noise signal received via the loop antenna LC2. Absent. That is, the disturbance noise signal may be detected from the noise signal received via the loop antenna LC1 while the changeover switch 86 is kept on the label creating loop antenna LC1 side (first detection circuit).

  FIG. 8 is a functional block diagram showing a functional configuration of the RFID circuit element To for label production (or information acquisition). In FIG. 8, the RFID circuit element To includes the loop antenna 152 that transmits and receives signals in a contactless manner with the loop antennas LC <b> 1 and LC <b> 2 on the tag label producing apparatus 1 side, and the loop antenna 152 connected to the loop antenna 152.

  The IC circuit unit 151 includes a rectification unit 153 that rectifies the interrogation wave received by the loop antenna 152, a power supply unit 154 that accumulates the energy of the interrogation wave rectified by the rectification unit 153, and serves as a drive power source. A clock extraction unit 156 that extracts a clock signal from the interrogation wave received by the loop antenna 152 and supplies the clock signal to the control unit 155, a memory unit 157 that can store a predetermined information signal, and a modulation / demodulation connected to the loop antenna 152 And a control unit 155 for controlling the operation of the RFID circuit element To via the memory unit 157, the clock extraction unit 156, the modulation / demodulation unit 158, and the like.

  The modem 158 demodulates the communication signal received from the loop antenna 152 from the loop antennas LC 1 and LC 2 of the tag label producing apparatus 1, modulates the return signal from the controller 155, and receives the signal from the loop antenna 152. Transmit as response wave.

  The control unit 155 interprets the received signal demodulated by the modulation / demodulation unit 158, generates a return signal based on the information signal stored in the memory unit 157, and returns the response signal from the loop antenna 152 by the modulation / demodulation unit 158. Basic control such as control is executed.

  FIG. 9 shows an example of the appearance of the RFID label T formed by completing the information writing (or reading) of the RFID circuit element To for label production To and the cutting of the tag label tape 109 with print by the tag label producing apparatus 1 having the above-described configuration. FIG. 9A is a top view, and FIG. 9B is a bottom view. FIG. 10A is a view obtained by rotating the transverse sectional view taken along the XA-XA ′ section in FIG. 9 by 90 ° counterclockwise, and FIG. 10B is the sectional view taken along the XB-XB ′ section in FIG. It is the figure which rotated the transverse cross section 90 degrees counterclockwise.

  9 and 10, the RFID label T has a five-layer structure in which the cover film 103 is added to the four-layer structure shown in FIG. 5 as described above, and the cover film 103 side (upper side in FIG. 10). To the opposite side (lower side in FIG. 10), the cover film 103, the adhesive layer 101a, the base film 101b, the adhesive layer 101c, and the release paper 101d constitute five layers. As described above, the RFID tag circuit element To for label production including the loop antenna 152 provided on the back side of the base film 101b is provided in the base film 101b and the adhesive layer 101c, and the label is produced on the back surface of the cover film 103. A label print R (in this example, “RF-ID” indicating the type of the RFID label T) corresponding to the stored information of the RFID tag circuit element To is printed.

  Also, the cover film 103, the adhesive layer 101a, the base film 101b, and the adhesive layer 101c are provided with the half-cut line HC (half-cut portion. However, in this example, substantially along the tape width direction by the half cutter 34 as described above. The front half-cut line HC1 and the rear half-cut line HC2 are formed. In the cover film 103, an area sandwiched between the half-cut lines HC1 and HC2 is a print area S on which the label print R is printed. Are a front margin area S1 and a rear margin area S2.

  In the tag label producing apparatus 1 having the basic configuration as described above, as described above, the label producing process for producing the RFID label T using the RFID circuit element To for producing the label in the housing 2A, and the tag label producing apparatus (1) Information acquisition processing for reading (acquiring) information from an external information acquisition RFID circuit element can be executed. In the label producing process, the base tape 101 provided with the label producing RFID circuit element To is conveyed by the tape feeding roller 27, and information is transmitted / received to / from the label producing RFID circuit element To via the label producing loop antenna LC1. The RFID label T is created. On the other hand, in the information acquisition process, predetermined wireless tag information is read and acquired by performing information transmission / reception with the information acquisition RFID circuit element To located outside the housing 2A via the information acquisition loop antenna LC2. The

  In the present embodiment, when the RFID label T is created, prior to executing the above-described label creation processing, it is used to send / receive information to / from the label creation RFID circuit element To (using the information acquisition loop antenna LC2). Disturbance noise detection processing for the first frequency is performed. The details will be described below with reference to FIGS.

  FIG. 11 is a flowchart showing the detailed procedure of the tag label creation process executed by the CPU 111 of the control circuit 110.

  In FIG. 11, first, in step S105, it is determined whether or not a tag label creation start operation (tag label creation instruction signal) has been performed by the PC 118 (a tag label creation instruction signal has been input via the input / output interface 113). This step S105 is repeated until there is a tag label creation start operation by the PC 118. If there is a tag label creation start operation by the PC 118, the determination is satisfied, and the routine proceeds to step S300 described above. In addition, the procedure of said step S105 comprises the signal input means as described in each claim.

  In step S300, a changeover control signal is output to the changeover switch 86 via the input / output interface 113 to switch to the information acquisition loop antenna LC2 to input a noise signal to the detection circuit 350 to perform noise detection processing (details will be described later). FIG. 12). Then, a determination result of the detection circuit 350, that is, whether or not the reception intensity of the noise signal is equal to or higher than a threshold (with disturbance noise) is input (without disturbance noise). If the determination result is that there is disturbance noise, the noise flag FN is set to FN = 1, and if there is no disturbance noise, FN = 0. Note that this determination itself may be executed on the control circuit 110 side instead of the detection circuit 350 side.

  In step S110, it is determined whether or not the above-described noise flag FN is zero. If the noise flag FN = 1 (disturbance noise is detected), the determination is not satisfied, and the process proceeds to step S115. If the noise flag FN = 0 (disturbance noise is not detected), the determination is satisfied, and step S125 is performed. Move on.

  In step S125, based on the operation signal from the PC 118 via the input / output interface 113, print data, communication data (writing data) with the RFID tag circuit element To for label production To, the front / rear half-cut position, and the full-cut position. Preparation processing for performing the setting and the like is executed. Convenience can be improved by operating and editing information necessary for this preparation process from the PC 118.

  Next, in step S130, when communication is performed from the label producing loop antenna LC1 to the label producing RFID circuit element To, a communication retry (retry) is performed when there is no response from the label producing RFID circuit element To. Variables M and N for counting the number of times to perform (number of access attempts) are initialized to 0 (see FIG. 14 described later).

  Thereafter, the process proceeds to step S135, where a control signal is output to the conveying motor drive circuit 121 via the input / output interface 113, and the tape feeding roller 27 and the ribbon take-up roller 106 are driven to rotate by the driving force of the conveying motor 119. Further, a control signal is output to the tape discharge motor 65 via the tape discharge motor drive circuit 123 to drive the drive roller 51 to rotate. Accordingly, the base tape 101 is fed out from the first roll 102 and supplied to the tape feed roller 27, and the cover film 103 is fed out from the second roll 104. The base tape 101 and the cover film 103 are The tape feeding roller 27 and the sub roller 109 are bonded and integrated to form a tag label tape 109 with print, which is conveyed.

  Thereafter, in step S140, based on the detection signal of the mark detection sensor 127 input via the input / output interface 113, whether or not the identifier PM of the base tape 101 is detected (in other words, the cover film 103 is printed by the print head 23). Whether the start position has been reached). If the identifier PM is detected, the determination is satisfied and the routine goes to the next Step S145. If the identifier PM is not detected (in other words, the cover film 103 has not reached the print start position), 140 is repeated until the identifier PM is detected.

  In step S145, a control signal is output to the print drive circuit 120 via the input / output interface 113, the print head 23 is energized, and the above-described print region S of the cover film 103 (= the base tape 101 at a predetermined pitch, etc.). Label printing R such as characters, symbols, barcodes, etc. corresponding to the print data generated in step S125 is printed on the back surface of the RFID circuit element To for label production arranged at intervals. Start.

  Thereafter, in step S150, whether or not the tag label tape 109 with print has been transported to the previous half-cut position set in the previous step S125 (in other words, the position where the half cutter 34 of the half-cut unit 35 faces the front half-cut line HC1). Whether the tag label tape 109 with print has reached) is determined. The determination at this time may be, for example, by detecting the transport distance after detecting the identifier PM of the base tape 101 in the above-described step S140 by a predetermined known method (transport for driving the transport motor 119 which is a pulse motor). The number of pulses output from the motor drive circuit 121 is counted).

  When the tag label tape 109 with print has reached the front half-cut position, the determination at step S150 is satisfied, and the routine goes to the next step S155.

  In step S155, a control signal is output to the transport motor drive circuit 121 and the tape discharge motor drive circuit 123 via the input / output interface 113, the drive of the transport motor 119 and the tape discharge motor 65 is stopped, and the tape feed roller 27 is stopped. Then, the rotation of the ribbon take-up roller 106 and the driving roller 51 is stopped. Thus, in the process in which the tag label tape 109 with print fed out from the cartridge 7 moves in the discharge direction, the half cutter 34 of the half cut unit 35 faces the front half cut line HC1 set in step S125. The feeding of the base tape 101 from the first roll 102, the feeding of the cover film 103 from the second roll 104, and the conveyance of the tag label tape 109 with print are stopped. At this time, a control signal is also output to the print drive circuit 120 via the input / output interface 113, the energization of the print head 23 is stopped, and printing of the label print R is stopped (print interruption).

  Thereafter, in step S160, a control signal is output to the half cutter motor drive circuit 128 via the input / output interface 113 to drive the half cutter motor 129 and rotate the half cutter 34 to cover the tag label tape 109 with print. A pre-half-cut process for cutting the film 103, the adhesive layer 101a, the base film 101b, and the adhesive layer 101c to form the front half-cut line HC1 is performed.

  Then, the process proceeds to step S165, and similarly to step S135, the tape feeding roller 27, the ribbon take-up roller 106, and the driving roller 51 are rotationally driven to resume the transport of the tag label tape 109 with print, and the same as step S145. Then, the print head 23 is energized to resume the printing of the label print R.

  After that, in step S170, the printed tag label tape 109 to be conveyed has a predetermined value (for example, the label producing RFID circuit element To to which the cover film 103 on which the corresponding printing has been applied is bonded is applied to the label producing loop antenna LC1. It is determined whether or not it has been transported by a transport distance that only reaches (). Similar to step S150, the conveyance distance at this time may be determined by counting the number of pulses output from the conveyance motor drive circuit 121 that drives the conveyance motor 119, which is a pulse motor.

  The determination in step S170 is repeated until the printed tag label tape 109 is conveyed by a predetermined value. When the printed tag label tape 109 is conveyed by a predetermined value, the determination in step S170 is satisfied, and the process proceeds to the next step S400.

  In the next step S200, tag access processing is performed. That is, when the label producing RFID circuit element To is conveyed to the communication position (the position where the label producing RFID circuit element To faces the label producing loop antenna LC1), the conveyance and printing are stopped, and information is transmitted / received. The conveyance and printing are resumed to complete the printing, and further, the conveyance is stopped at the rear half-cut position, and the rear half-cut line HC2 is formed (see FIG. 13 described later).

  When step S200 is completed as described above, the process proceeds to step S175 (note that at this time, the transport of the tag label tape 109 with print has been resumed in step S200). In step S175, whether or not the tag label tape 109 with print has been transported to the full cut position described above (in other words, the tag label tape with print to the position where the movable blade 41 of the cutting mechanism 15 faces the full cut position set in step S105). 109) is determined. The determination at this time is also the same as described above, for example, by detecting the transport distance after detecting the identifier PM of the base tape 101 in step S140 by a predetermined known method (a transport motor 119 which is a pulse motor). The number of pulses output from the conveyance motor drive circuit 121 that drives the motor is counted, etc.). This procedure is repeated until the full cut position is reached, and the determination is satisfied.

  In step S180, similarly to step S155, the rotation of the tape feeding roller 27, the ribbon take-up roller 106, and the driving roller 51 is stopped, and the conveyance of the tag label tape 109 with print is stopped. As a result, the base tape 101 is fed from the first roll 102 and the cover film 103 is fed from the second roll 104 with the movable blade 41 of the cutting mechanism 15 facing the full cut position set in step S125. , And the transport of the tag label tape 109 with print is stopped.

  Thereafter, in step S185, a control signal is output to the cutter motor drive circuit 122 to drive the cutter motor 43, and the movable blade 41 of the cutting mechanism 15 is rotated to cover the cover film 103 of the tag label tape 109 with print, adhesive A full cut process is performed in which the layer 101a, the base film 101b, the adhesive layer 101c, and the release paper 101d are all cut (divided) to form a cutting line. The RFID tag label T in the form of a label is separated from the printed tag label tape 109 by the cutting mechanism 15 and the RFID tag information of the RFID circuit element To for label production is read and a predetermined printing corresponding to this is performed. Is generated.

  Thereafter, the process proceeds to step S190, where a control signal is output to the tape discharge motor drive circuit 123 via the input / output interface 113, the drive of the tape discharge motor 65 is restarted, and the drive roller 51 is rotated. As a result, the conveyance by the driving roller 51 is resumed, and the RFID label T generated in the label shape in step S185 is conveyed toward the label discharge port 11 and discharged from the label discharge port 11 to the outside of the apparatus. Exit.

  On the other hand, in step S115, in response to detection of disturbance noise, an alarm display signal (noise notification signal) is output to the PC 118 outside the label producing apparatus 1 and the LED 91 inside the label producing apparatus 1 via the input / output interface 113. To do. As a result, an alarm display such as characters, images or sounds is displayed on the display screen of the PC 118, and the operator on the PC 118 side can be surely notified and recognized that the radio wave environment is not good due to the generation of disturbance noise. Further, the LED 91 of the label producing apparatus 1 is lit, and the operator is informed of disturbance noise by visual notification so as to be surely recognized. When step S115 is completed, the process proceeds to step S120. In addition, the procedure of this step S115 comprises the signal output means as described in each claim.

  In step S120, whether or not the operator who has been informed that the radio wave environment is not good due to the occurrence of disturbance noise has performed a label generation stop operation (whether an instruction signal for stopping tag label generation has been input via the input / output interface 113). ). If the operator performs a label creation stop operation, the determination is satisfied, and this flow ends.

  If the operator does not perform the label creation stop operation in step S120 described above, the determination is not satisfied, and the process returns to step S300 and the same procedure is repeated after the noise detection process (cooperation control unit). Thereby, after the output of the alarm display signal in step S115, when no disturbance noise is detected for the first frequency, the determination in step S110 is satisfied, and tag label generation in step S125 and subsequent steps is performed. That is, even if the generation of the disturbance noise is not started due to the start of the generation of the tag label, if the disturbance noise disappears thereafter, the tag label generation is started quickly, and the RFID label T is surely attached. Can be created.

  FIG. 12 is a flowchart showing the detailed procedure of step S300.

  In FIG. 12, first, in step S310, a switching control signal is output to the selector switch 86 via the input / output interface 113, and the antenna duplexer 240 is switched to connect to the information acquisition loop antenna LC2.

  Thereafter, the process proceeds to step S320, in which it is determined whether or not the determination result of the reception intensity determination means of the detection circuit 350 input / output via the input / output interface 113 is disturbance noise (reception intensity is greater than or equal to a threshold value). If the loop antenna LC2 receives a noise signal whose reception intensity is equal to or higher than the threshold, the determination is satisfied, and the routine goes to Step S330. If the determination is not satisfied, the process moves to step S340.

  In step S330, in response to the determination in step S320 being satisfied, the noise flag FN indicating whether there is disturbance noise is set to FN = 1 (with disturbance noise), and this routine is terminated. On the other hand, in step S340, in response to the determination in step S320 not being satisfied, the noise flag FN is set to FN = 0 (no disturbance noise), and this routine is terminated.

  FIG. 13 is a flowchart showing the detailed procedure of step S200 described above.

  First, in step S210, it is determined whether or not the tag label tape 109 with print has been transported to the communication position with the label producing loop antenna LC1 described above. The determination at this time may be performed by a predetermined known method, for example, after detecting the identifier PM of the base tape 101 in step S140, as in step S150 of FIG. 11 described above.

  When the tag label tape 109 with print has not reached the communication position, the determination is not satisfied. The procedure of step S210 is repeated until the determination is satisfied. When the tape label tape 109 has reached the communication position, the determination is satisfied and the process proceeds to the next step S220.

  In step S220, as in step S155, the rotation of the tape feeding roller 27, the ribbon take-up roller 106, and the driving roller 51 is stopped, and the label producing loop antenna LC1 is substantially connected to the label producing RFID circuit element To. In contrast, the transport of the tag label tape 109 with print stops. Further, the energization of the print head 23 is stopped, and the printing of the label print R is stopped (interrupted).

  Subsequently, in step S400, information is transmitted / received between the label producing loop antenna LC1 and the label producing RFID circuit element To by radio communication using the high frequency (UHF band) of the first frequency to produce the label producing An information transmission / reception process is performed in which the information created in step S105 of FIG. 11 is written into the IC circuit unit 151 of the RFID circuit element To (or the information stored in advance in the IC circuit unit 151 is read) (details will be described later) (See FIG. 14).

  Thereafter, the process proceeds to step S230, and similarly to step S165 in FIG. 11, the tape feeding roller 27, the ribbon take-up roller 106, and the driving roller 51 are rotationally driven to resume the transport of the tag label tape 109 with print and the printing. The head 23 is energized to resume printing the label print R.

  Thereafter, the process proceeds to step S240, and it is determined whether or not the tag label tape 109 with print has been transported to the aforementioned print end position (calculated in step S125 in FIG. 11). The determination at this time may also be detected by a predetermined known method, for example, after detecting the identifier PM in step S140, as described above. The determination is not satisfied until the print end position is reached, and this procedure is repeated. When the print end position is reached, the determination is satisfied and the routine goes to the next Step S250.

  In step S250, as in step S155 in FIG. 11, the energization of the print head 23 is stopped, and the printing of the label print R is stopped. Thereby, the printing of the label print R on the print region S is completed.

  Thereafter, the process proceeds to step S260, and after the sheet is transported to a predetermined rear half-cut position, a post-half cut process is performed in which the rear half-cut line HC2 is formed by the half cutter 34. This routine is completed as described above.

  FIG. 14 is a flowchart showing the detailed procedure of step S400 described above. In this example, information writing will be described as an example of the information writing and information reading described above.

  In FIG. 14, first, in step S405, a switching control signal is output to the changeover switch 86 via the input / output interface 113 to connect the antenna duplexer 240 and the label producing loop antenna LC1.

  Thereafter, the process proceeds to step S410, where a control signal is output to the transmission circuit 306 via the input / output interface 113, and a tag ID read command signal is transmitted. That is, the transmitter circuit 306 performs a predetermined modulation to obtain a query wave for acquiring the ID information stored in the RFID circuit element To for label production To (in this example, the tag ID read command signal as an inquiry signal). ) Is generated. Then, the tag ID read command signal is transmitted to the RFID tag circuit element To to be written via the label producing loop antenna LC1. As a result, the memory unit 157 of the label producing RFID circuit element To is initialized.

  Thereafter, in step S415, the reply signal (including the tag ID) transmitted from the RFID tag circuit element To to be written in response to the tag ID read command signal is sent via the label creation loop antenna LC1. Receive and capture via the receiving circuit 307 and the input / output interface 113.

  Next, in step S420, based on the received reply signal, it is determined whether or not the tag ID of the label producing RFID circuit element To has been normally read.

  If the determination is not satisfied, the process moves to step S425, 1 is added to M, and it is further determined in step S430 whether M = 5. If M ≦ 4, the determination is not satisfied and the routine returns to step S410 and the same procedure is repeated. If M = 5, the process proceeds to step S435, and an error display signal is output to the PC 118 via the input / output interface 113, the corresponding writing failure (error) display is performed, and this routine is terminated. In this way, even if initialization is not successful, retry is performed up to five times.

  When the determination in step S420 is satisfied, the process proceeds to step S440, where a control signal is output to the transmission circuit 306 via the input / output interface 113, and a Write command signal is transmitted. In other words, the transmission circuit 306 performs predetermined modulation, thereby specifying the tag ID read in step S415 and writing the desired data to the memory unit 157 of the label creating RFID circuit element To ( In this example, the write command signal) is generated. Then, the write command signal is transmitted to the RFID tag circuit element To for label creation to which information is to be written via the label creation loop antenna LC1 to write information.

  Thereafter, in step S445, a control signal is output to the transmission circuit 306 via the input / output interface 113, and a Read command signal is transmitted. That is, the transmission circuit 306 performs a predetermined modulation to specify the tag ID read in step S415 and to read the data recorded in the memory unit 157 of the label creation RFID circuit element To. (In this example, the above Read command signal) is generated. Then, this Read command signal is transmitted to the RFID tag circuit element To for label creation to which information is written via the label creation loop antenna LC1 to prompt a reply.

  Thereafter, in step S450, the reply signal transmitted from the RFID tag circuit element To to be written corresponding to the Read command signal is received via the label creating loop antenna LC1 and taken in via the receiving circuit 307. .

  In step S455, information stored in the memory unit 157 of the label generation RFID circuit element To is confirmed based on the received reply signal, and a known error detection code (CRC code; Cyclic Redundancy Check, etc.) is checked. ) Is used to determine whether or not the transmitted predetermined information is normally stored in the memory unit 157.

  If it is not stored normally, the determination is not satisfied, the process moves to step S460, 1 is added to N, and it is further determined in step S465 whether N = 5. If N ≦ 4, the determination is not satisfied and the routine returns to step S440 and the same procedure is repeated. If N = 5, the process proceeds to step S435 described above, and similarly a writing failure (error) display corresponding to the PC 118 is performed, and this routine is terminated. In this way, even if information writing is not successful, retry is performed up to five times.

  If the storage has been performed normally in step S455, the determination is satisfied, and the routine goes to step S470. In step S470, a control signal is output to the transmission circuit 306, and a lock command signal is transmitted. That is, the transmission circuit 306 performs predetermined modulation to specify the tag ID read in step S415 and prohibit overwriting of data recorded in the memory unit 157 of the label generation RFID circuit element To. Interrogation waves (in this example, the lock command signal) are generated. Then, this lock command signal is transmitted to the label creation RFID circuit element To as the information writing target via the label creation loop antenna LC1, and new information is written to the label creation RFID circuit element To. Ban. Thereby, the information writing to the RFID tag circuit element To for label production to be written is completed.

  Thereafter, the process proceeds to step S480, where the information written in the RFID tag circuit element To for label production in step S440 and the print information of the label print R already printed in the print area S by the print head 23 are associated with this information. Is output via the input / output interface 113 and the communication line NW, and stored in the information server IS or the route server RS. This stored data is stored and held in the database of each server IS, RS, for example, so that it can be referred to from the PC 118 as necessary. This routine is completed as described above.

  As described above, according to the label producing apparatus 1 of the present embodiment, the label producing loop antenna LC1 uses the first frequency for the label producing RFID circuit element To provided in the base tape 101. Information is transmitted and received by wireless communication, and a RFID label T is created. Prior to the label creation process, the disturbance noise detection process is executed using the detection circuit 350 at the time when a label creation start operation is performed from the PC 118. If there is disturbance noise with respect to the first frequency used when creating the label, an alarm display signal is output to the PC 118 or the like to notify the operator that there is disturbance. Therefore, it is possible to prevent a defective tag label from being erroneously created in an unstable communication state with disturbance noise. As a result, it is possible to improve the quality and reliability of the RFID label produced.

  In the present embodiment, in particular, the detection circuit 350 performs noise detection based on reception by the information acquisition loop antenna LC2 different from the label creation loop antenna LC1. Thereby, the noise detection function and the original communication function for label production can be distinguished and shared by separate antennas.

  In the present embodiment, in particular, a frequency in the UHF band is used as a frequency (first frequency) used for creating the RFID label T. That is, when the frequency of the UHF band is used, the communication distance is relatively longer than when the frequency of the HF band or the like is used. Therefore, the tag label is easily affected by the surrounding radio wave environment. Therefore, various measures corresponding to the detection of disturbance noise as described above are more effective.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described in order.

(1) When switching frequency In the above embodiment, when disturbance noise for the first frequency used at the time of label creation is detected, the operator is notified that there is a disturbance, and the operator creates the label. Abandoned (or resumes label creation when disturbance noise is gone). On the other hand, in the present modification, when disturbance noise with respect to the first frequency used at the time of label production is detected, the label production is performed by switching to the second frequency different from the first frequency.

  FIG. 15 is a functional block diagram showing detailed functions of the high-frequency circuit provided in the label producing apparatus of the present modification.

  In FIG. 15, the tag label producing apparatus 1 of the present modification includes a high-frequency circuit 32A corresponding to the first frequency and a high-frequency circuit 32B corresponding to the second frequency (which is a frequency different from the first frequency in the UHF band). It has. Further, the control circuit 110 includes a frequency switching control unit 110A (frequency switching means). Based on a signal from the frequency switching control unit 110A, a first command signal (described later) from the high frequency circuit 32A using the first frequency and a second command signal from the high frequency circuit 32B using the second frequency are selected. Can be output to the label creation loop antenna LC1 and the information acquisition loop antenna LC2 and can be switched to perform wireless communication with the label creation RFID circuit element To and the information acquisition RFID circuit element To. It has become.

  The configuration of the high-frequency circuits 32A and 32B is basically the same as that of the high-frequency circuit 32 described above. That is, the high frequency circuit 32A includes a transmission circuit 306A, a reception circuit 307A, and a transmission / reception separator 340A.

  The transmission circuit 306A is a block that generates an interrogation wave (first frequency) for accessing the RFID circuit element To in response to a carrier wave generation command signal from the frequency switching control unit 110A of the control circuit 110. Then, the crystal resonator 335A, PLL 336A, VCO 337A, and transmission multiplier circuit 338A having the same functions as the crystal resonator 335, PLL 336, VCO 337, transmission multiplier circuit 338, and transmission amplifier 339 of the high-frequency circuit 32 of the above embodiment, respectively. And a transmission amplifier 339A. The PLL 336A and the transmission multiplication circuit 338A constitute first command generation means for generating a first command signal using the first frequency described in the claims.

  The reception circuit 307A includes a reception first multiplication circuit 340, a first band pass filter 341, a first limiter 342, a reception first amplifier 343, a reception second multiplication circuit 344, and a second band pass filter of the high frequency circuit 32 of the above embodiment. 345, a second limiter 346, a reception second amplifier 347, and a reception first multiplication circuit 340A, a first bandpass filter 341A, a first limiter 342A, a reception first amplifier 343A, a reception second A multiplication circuit 344A, a second band pass filter 345A, a second limiter 346A, and a reception second amplifier 347A are provided. The signal “RXS-I” output from the first limiter 342A and the signal “RXS-Q” output from the second limiter 346A are input to the control circuit 110 and processed. The outputs of the reception first amplifier 343A and the reception second amplifier 347A are also input to the RSSI circuit 348A, and the intensity signal “RSSI” is input to the control circuit 110.

  At this time, the reception circuit 307A has a detection circuit 350A (second detection) for detecting disturbance noise with respect to the communication frequency (first frequency) used for transmission / reception of information with the label producing RFID circuit element To as noise detection means. Circuit). As in the above embodiment, the detection circuit 350A detects a noise signal for the first frequency received by the information acquisition loop antenna LC2 and extracts the received intensity. Then, it is determined whether or not the reception strength of the noise signal is greater than or equal to a threshold value by a reception strength determination means (not shown), and the result is output to the control circuit 110.

  Similarly to the above, the transmission circuit 306B is a block that generates an interrogation wave (second frequency) for accessing the RFID circuit element To in response to a carrier wave generation command signal from the frequency switching control unit 110A of the control circuit 110. The crystal resonator 335B, PLL 336B, VCO 337B, and transmission multiplier circuit 338B having the same functions as the crystal resonator 335, PLL 336, VCO 337, transmission multiplication circuit 338, and transmission amplifier 339 of the high-frequency circuit 32 of the above embodiment, respectively. And a transmission amplifier 339B. The PLL 336B and the transmission multiplication circuit 338B constitute second command generation means for generating a second command signal using the second frequency described in the claims.

  The reception circuit 307B includes a reception first multiplication circuit 340, a first band pass filter 341, a first limiter 342, a reception first amplifier 343, a reception second multiplication circuit 344, and a second band pass filter of the high frequency circuit 32 of the above embodiment. 345, a second limiter 346, a reception second amplifier 347, and a reception first multiplication circuit 340B, a first bandpass filter 341B, a first limiter 342B, a reception first amplifier 343B, a reception second A multiplication circuit 344B, a second band pass filter 345B, a second limiter 346B, and a reception second amplifier 347B are provided. The signal “RXS-I” output from the first limiter 342B and the signal “RXS-Q” output from the second limiter 346B are input to the control circuit 110 and processed. The outputs of the reception first amplifier 343B and the reception second amplifier 347B are also input to the RSSI circuit 348B, and the intensity signal “RSSI” is input to the control circuit 110.

  At this time, the reception circuit 307B has a detection circuit 350B (second detection) that detects disturbance noise with respect to the communication frequency (second frequency) used for transmission / reception of information to / from the label producing RFID circuit element To as noise detection means. Circuit). This detection circuit 350B detects the noise signal for the second frequency received by the information acquisition loop antenna LC2 in the same manner as described above, and extracts the received intensity. Then, it is determined whether or not the reception strength of the noise signal is greater than or equal to a threshold value by a reception strength determination means (not shown), and the result is output to the control circuit 110.

  FIG. 16 is a flowchart showing a detailed procedure of tag label creation processing in the present modification, and corresponds to FIG. 11 of the above embodiment. In the flow of FIG. 16, step S112 is provided instead of steps S115 and S120 of FIG. That is, if it is determined in step S110 that the noise flag FN is not FN = 0, that is, there is disturbance noise, the process proceeds to a newly provided step S112.

  In step S112, a frequency switching signal (corresponding to a control signal output corresponding to disturbance detection) is output to the frequency switching control unit 110A (signal output means). Thereby, the PLL 336A of the transmission circuit 307A and the PLL 336B of the transmission circuit 307B are controlled in cooperation, and the frequency used for label production is switched from the first frequency to the second frequency. That is, the frequency switching control unit 110A stops the generation of the carrier wave of the first frequency for the PLL 336A until then (stops the output of the control signal or outputs a control signal for stopping, etc.) Instead, a control signal is output to the PLL 336B to generate a second frequency carrier wave. As a result, the used frequency is switched.

  When step S112 is completed, the process proceeds to step S125. Since the subsequent steps are the same as those in the above embodiment, the description thereof is omitted.

  According to this modification, first, when a disturbance noise is detected in the detection circuit 350A when the transmission circuit 306A tries to create the tag label T using the first frequency (step S110), the use frequency is changed to the second frequency. Switching (step S112). Then, the transmission circuit 306B communicates with the RFID tag circuit element To for label production To create the RFID label T (step S125 to step S190). As a result, stable and good communication can be performed with the label producing RFID circuit element To in a state where there is no adverse effect due to disturbance noise on the first frequency. As a result, it is possible to prevent the production of a defective tag label and improve the quality and reliability of the RFID tag label.

(2) Case of performing shielding detection of outer portion FIG. 17 is a functional block diagram showing a control system of the tag label producing apparatus 1 in this modification. In FIG. 17, an open / close sensor 201 capable of detecting the rotation state (whether completely closed or not) of the open / close lid 3 (or the front lid 12) is provided, and the detection result is controlled via the input / output interface 113. Input to the CPU 111 of the circuit 110.

  FIG. 18 is a flowchart showing the detailed procedure of the tag label creation process executed by the CPU 111 of the control circuit 110 provided in the tag label creation device 1 in this modification, and corresponds to FIG. 11 of the above embodiment.

  The flow shown in FIG. 18 is different from FIG. 11 in that step S201, step S202, and step S203 are newly added.

  That is, when the above-described noise flag FN = 1 in step S110 (disturbance noise is detected), the determination is not satisfied and the process proceeds to newly provided step S201.

  In step S201, it is determined whether a part of the outline is open. Specifically, based on the detection result of the rotation state of the opening / closing lid 3 (or the front lid 12) by the sensor 201, it is determined whether or not the opening / closing lid 3 (or the front lid 12) is completely closed. If it is completely closed, the determination is satisfied, and the outer portion is regarded as being in a substantially sealed radio wave shielding state, and the process proceeds to step S115 described above. Since the subsequent steps are the same as described above, description thereof is omitted.

  On the other hand, if the open / close lid 3 (or the front lid 12) is not completely closed, the determination is not satisfied, and the radio wave shielding state by the outer portion is regarded as insufficient, and the process proceeds to step S202 newly provided.

  In step S202, a shielding warning signal is output to the PC 118 outside the label producing apparatus 1 and the LED 91 in the label producing apparatus 1 via the input / output interface 113, as in step S115. As a result, similarly to the above, an alarm display (a warning that radio wave shielding by the outer portion is insufficient) is performed on the display screen of the PC 118 with characters, images, sounds, or the like. Thus, the operator on the PC 118 side can be surely notified and recognized that the open / close lid 3 (or the front lid 12) is not completely closed and the radio wave shielding may be insufficient. it can. Further, lighting and display corresponding to the LED 91 of the label producing apparatus 1 are performed, and the above contents are overlapped and notified to the operator by visual notification so as to ensure reliable recognition. When step S202 ends, the process proceeds to step S203.

  In step S203, in response to the warning in step S202, it is determined whether the opening / closing sensor 201 detects that the opening / closing lid 3 (or the front lid 12) is completely closed. The determination is not satisfied until the opening / closing lid 3 (or the front lid 12) is completely closed, and the loop waits. When the opening / closing lid 3 (or the front lid 12) is completely closed, the determination in step S203 is satisfied, and the above-described steps. Returning to S300, the same procedure is repeated. Other procedures are the same as those in FIG.

  In the case where noise is detected using radio waves received via the information acquisition loop antenna LC2 provided in the outer part (the apparatus main body 2 and the opening / closing lid 3) as in the tag label producing apparatus 1, for example, the opening / closing lid 3 described above. In addition, forgetting to close or forgetting to close the front lid 12 may cause an opening that should not be present, and radio wave shielding may be insufficient. In this modification, when disturbance noise is detected in the noise detection process of step S300, and when the opening / closing sensor 201 detects that the opening / closing lid 3 and the front lid 12 are not completely closed, step S202 is performed. Outputs a shielding warning signal. Thereby, the operator can appropriately take countermeasures for improving the shielding according to the above.

  In addition, although the above demonstrated the case where the noise by the insufficient closing state of the opening-and-closing lid 3 and the front lid 12 was considered, it is not restricted to this. That is, even if the opening / closing lid 3 and the front lid 12 are sufficiently closed, the opening at the opening provided in the outer portion of the tag label producing apparatus 1 such as the label discharge port 11 is insufficient. There is also a possibility. Therefore, in consideration of this, for example, when the determination is not satisfied in step S201 in FIG. 18 and an alarm is displayed in step S115, in addition to performing the notification in the meaning of “prompt for label creation stop operation” as described above. (Alternatively, in place of the notification,) “Prompt the inspection of the shielding state in the vicinity of the discharge port 11” is notified, and for example, the above-described shield member 85 (or other shield member (not shown)) is dropped or damaged. Etc. may be prompted.

(3) Others In the above, the case where the RFID label T is created by the operation from the PC 118 outside the tag label producing device 1 has been described as an example, but the present invention is not limited to this. That is, a tag label creation instruction may be given by an appropriate operation means provided in the device body 2 of the tag label creation device 1. In this case, the operation signal of the operation means is input to the CPU 111 via the input / output interface 113 (signal input means), and the RFID label T is created based on this.

  Moreover, in the above, it was the system which prints on the cover film 103 different from the base tape 101 provided with the RFID circuit element To for label production, and bonds these together, However, it is not restricted to this, For example, a tag The present invention is applied to a system (a type in which bonding is not performed) in which printing is performed on a print area (a heat-sensitive layer made of a heat-sensitive material, a transfer layer made of a transfer-receiving material, and an image-receiving layer made of an image-receiving material) provided on the tape. May be applied.

  Further, in the above, the case where the RFID label T is created by cutting the printed tag label tape 109 that has completed access (reading or writing) to the RFID tag circuit element To for printing and labeling by the cutting mechanism 15 is taken as an example. Although explained, it is not limited to this. That is, when the label mount (so-called die-cut label) separated in advance to a predetermined size corresponding to the label is continuously arranged on the tape fed out from the roll, the cutting mechanism 15 does not need to cut the label mount. After the tape has been discharged from the label discharge port 11, the RFID label label T is created by removing only the label mount (the one with the already-accessed RFID tag circuit element To for label production and the corresponding printing) from the tape. The present invention may be applied to such a case.

  The present invention is not limited to the above-described embodiments and modifications, and various modifications can be made without departing from the spirit and technical idea thereof.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
