Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a puncturing device, a biological sample measuring apparatus and a biological sample measuring system that do not start performing puncturing operation by mistake. 
       BACKGROUND ART 
       [0002]    Patent literature 1 discloses a bodily fluid sampling device that can readily and reliably sample bodily fluid, with a simple configuration. A puncturing device described in Patent Literature 1 has a puncturing needle to puncture skin, a puncturing needle holding section that holds a puncturing needle and a biasing spring that applies biasing force to the puncturing needle holding section. In addition, the above-described puncturing device has a magnetic force retaining section that retains the puncturing holding portion in the base end side of the puncturing device by magnetic force, and a retention releasing section that has a solenoid to generate a magnetic field in a direction to offset the magnetic force of the magnetic force retaining section. 
         [0003]    In order to perform puncturing, the user first compresses the biasing spring by drawing the puncturing needle holding section to the base end side of the puncturing device to lock the puncturing needle holding section in the magnetic force retaining section. Then, the user performs the operation including pressing a puncturing execution button, so that the retention releasing section applies a voltage to the solenoid to cancel the locked state. By this means, the puncturing needle projects from the tip of the puncturing device to puncture skin. 
         [0004]    The above-described puncturing device has a configuration to electrically drive the retention releasing section. Therefore, a puncturing needle is released from being retained by the magnetic force retaining section by conducting electricity to the retention releasing section, so that it is possible to start the puncturing operation of the puncturing needle. In addition, the puncturing operation of a puncturing needle is started by energizing the retention releasing section, and therefore, when the puncturing execution button is pressed in a defective condition in which the retention releasing section does not completely and adequately apply a voltage to the solenoid, the puncturing operation of a puncturing needle is not started. In this way, this conventional puncturing device can prevent the puncturing operation of a puncturing needle from being started unexpectedly, in a condition in which electrical release requirements are not satisfied.

       SUMMARY OF INVENTION 
     Technical Problem 
       [0006]    However, even if the conventional puncturing device has a configuration to electrically perform releasing of the puncturing needle holding section from the locked state, it is not possible to prevent the puncturing operation of a puncturing needle from being started unexpectedly if electrical requirements for releasing are satisfied. For example, a case is possible where a child plays with this puncturing device, not only a case where biological samples are measured. Then, a case is possible where electrical release requirements are satisfied unexpectedly in process of playing with the puncturing device. Conventionally, there has been a problem that, when a puncturing device is operated for purposes other than measurement of biological samples, the puncturing operation of a puncturing needle is likely to be started unexpectedly. 
         [0007]    It is therefore an object of the present invention to provide a puncturing device, a biological sample measuring apparatus and a biological sample measuring system that prevents a puncturing needle from unexpectedly starting puncturing operation when the puncturing device is operated for purposes other than measurement of biological samples. 
       Solution to Problem

         [0009]    The biological sample measuring apparatus according to the present invention that measures a biological sample obtained by puncturing by means of a puncturing device adopts a configuration to include: a biological sample measuring section that measures a biological sample; and a radio communication section that transmits a puncturing allowing signal that allows the puncturing device to perform puncturing, when the biological sample measuring section is ready to start measurement. 
         [0010]    The biological sample measuring system according to the present invention including a puncturing device and a biological sample measuring apparatus that measures a biological sample obtained by puncturing by means of the puncturing device, wherein: the puncturing device includes: a puncturing mechanism that actuates a puncturing needle; a puncturing mechanism control section that controls the puncturing mechanism to allow/disallow puncturing operation; radio communication section that receives a radio signal from the biological sample measuring apparatus; and a control section that releases the puncturing mechanism control section from restricting and disallowing puncturing when the radio communication section receives a predetermined radio signal, and the biological sample measuring apparatus includes: a biological sample measuring section that measures a biological sample; and a radio communication section that transmits a puncturing allowing signal that allows the puncturing device to perform puncturing, when the biological sample measuring section is ready to start measurement. 
       ADVANTAGEOUS EFFECTS OF INVENTION 
       [0011]    According to the present invention, it is possible to disallow the puncturing operation of a puncturing device unless a biological sample measuring apparatus resides nearby the puncturing device and is ready to perform measurement. Therefore, it is possible to realize a puncturing device, a measuring apparatus and a measuring system that prevents a puncturing needle from unexpectedly starting puncturing operation when the puncturing device is operated for purposes other than measurement of biological samples.

     DESCRIPTION OF EMBODIMENTS 
       [0026]    Now, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 
       Embodiment 1 
       [0027]      FIG. 1  is a cross sectional view showing a puncturing device according to Embodiment 1 of the present invention.  FIG. 1A  shows a state in which puncturing is disabled, and  FIG. 1B  shows a state in which puncturing is enabled and biasing force is applied. The present embodiment is an example in which the present invention is applied to a puncturing device having a puncturing needle to puncture skin, a puncturing needle holding section that holds the puncturing needle, and a biasing spring to apply biasing force to the puncturing needle holding section. 
         [0028]    As shown in  FIG. 1 , biological sample measuring system  1  has puncturing device  100 , and external registration device  200  that transmits puncturing allowing request signals to puncturing device  100 . 
         [0029]    Puncturing device  100  has casing  101 , puncturing mechanism  110 , puncturing mechanism control section  120  and substrate  130  which are arranged in casing  101 , and radio communication section  140  and puncturing control circuit  150  which are placed on substrate  130 . Casing  101  is a cylindrical housing and accommodates puncturing mechanism  110 , puncturing mechanism control section  120  and substrate  130 . 
         [0030]    External registration device  200  transmits puncturing allowing request signals to puncturing device  100 . For example, external registration device  200  is a biological sample measuring apparatus that has a biological sample measuring means for measuring biological samples and a radio communication means for transmitting a puncturing allowing request signal to puncturing device  100  when the biological sample measuring means is ready to perform measurement. 
         [0031]    [Puncturing Mechanism  110 ] 
         [0032]    Puncturing mechanism  110  has puncturing needle  111  to puncture skin and puncturing needle holding section  113  that holds puncturing needle  111  in tip part  112 . In addition, puncturing mechanism  110  has biasing spring  114  that biases puncturing needle holding section  113  in the direction to project puncturing needle holding section  113  toward tip side  102  of puncturing device  100 , and biasing operation section  115  that pulls puncturing needle holding section  113  to the rear end side (opposite to tip side  102 ) of puncturing device  100 . 
         [0033]    Locking convex part  116  that locks puncturing needle holding section  113  is provided on the side surface of puncturing needle holding section  113 . The rear end side (opposite to tip part  112 ) of puncturing needle holding section  113  is connected to biasing operation section  115  via spring  117 . As shown in  FIG. 1B , the user pulls biasing operation section  115  to the rear end side of puncturing device  100  to compress biasing spring  114  and move puncturing needle holding section  113  to the biased position. Biasing operation section  115  is a knob part for pulling operation by the user against biasing spring  114 . 
         [0034]    Biasing control convex part  118  to limit movement of biasing operation section  115  to the rear end side of puncturing device  100 , is provided on the side surface of biasing operation section  115 . 
         [0035]    [Puncturing Mechanism Control Section  120 ] 
         [0036]    Puncturing mechanism control section  120  controls whether or not to enable puncturing mechanism  110  to perform puncturing. Puncturing mechanism control section  120  has locking mechanism  121 , biasing control mechanism  122  and puncturing control circuit  150  placed on substrate  130 . 
         [0037]    Locking mechanism  121  is composed of locking ring  123  and locking ring spring  124 . 
         [0038]    Locking ring  123  is an annular component through which puncturing needle holding section  113  penetrates. Locking ring  123  abuts on locking convex part  116  provided on the side surface of puncturing needle holding section  113  when puncturing needle holding section  113  moves to the biased position. By this means, locking ring  123  locks puncturing needle holding section  113  in the biased position. In addition, as shown in  FIG. 1 , locking ring  123  is provided with puncturing trigger  123   a  projecting from casing  101  to the exterior in the position facing locking ring spring  124 . 
         [0039]    Locking ring spring  124  contacts the end of locking ring  123  opposite to puncturing trigger  123   a  to consistently apply force to make puncturing trigger  123   a  project from casing  101 . The user presses puncturing trigger  123   a  to release puncturing needle holding section  113  from the locked state (perform puncturing). By this operation, locking ring spring  124  is compressed to release the contact state between locking ring  123  and locking convex part  116 , and resultant biasing force makes puncturing mechanism  110  perform puncturing operation. 
         [0040]    Biasing control mechanism  122  is formed by biasing control ring  125 , biasing control ring spring  126 , permanent magnet  127  and solenoid  128 . Biasing control mechanism  122  switches whether or not to enable the user to apply biasing force to puncturing mechanism  110 , based on a control signal outputted from puncturing control circuit  150 . 
         [0041]    Biasing control ring  125  is an annular component to which biasing operation section  115  penetrates. Permanent magnet  127  is embedded in one end of biasing control ring  125 , and biasing control ring sprig  126  contacts the other end. 
         [0042]    If the user pulls biasing operation section  115  to the rear end side (opposite to tip part  112 ) of puncturing device  100  when puncturing is not enabled (in a state in which the operation of biasing operation section  115  is disabled), biasing control ring spring  126  applies biasing force to biasing control ring  125 . To be more specific, biasing control ring spring  126  applies biasing force to biasing control ring  125  to retain biasing control ring  125  in the position in which biasing control convex part  118  provided on the side surface of biasing operation section  115  interferes with biasing control ring  125 . 
         [0043]    Biasing control ring spring  126  is partly or entirely accommodated in a concave part of the inner wall of casing  101 . As shown in  FIG. 1B , when puncturing is enabled, biasing control ring spring  126  is compressed by basing control ring  125 . 
         [0044]    Solenoid  128  is embedded in the inner wall of casing  101  contacting one end side in which permanent magnet  127  in biasing control ring  125  is embedded. Repulsive force works between permanent magnet  127  and solenoid  128  due to a magnetic field generated by solenoid  128 . When repulsive force works between permanent magnet  127  and solenoid  128 , biasing control ring  125  is pressed on biasing control ring spring  126 . This pressing force makes biasing control ring spring  126  be compressed, and biasing control ring  125  moves to the inner wall side of case  101  in which biasing control ring spring  126  is accommodated, as shown in  FIG. 1B . As a result of this, interference between biasing control ring  125  and biasing control convex part  118  is cancelled. 
         [0045]    By this means, the user can pull biasing operation section  115  to the rear end side, so that it is possible to lock puncturing needle holding section  113  in the biased position. 
         [0046]    [Radio Communication Section  140 ] 
         [0047]    Radio communication section  140  is formed by a communication module that performs bidirectional radio communication with a radio communication means in external registration device  200  using, for example, a weak radio frequency band of 300 MHz. The power consumption of this communication module is low. 
         [0048]    Radio communication section  140  receives radio signals from external registration device  200  using a specific short-range radio communication scheme. Alternatively, radio communication section  140  receives radio signals from external registration device  200 , using a low power short-range bidirectional radio communication scheme, such as Bluetooth (registered trademark) and UWB. 
         [0049]    [Puncturing Control Circuit  150 ] 
         [0050]    Puncturing control circuit  150  is electrically connected with solenoid  128  to control whether or not to make solenoid  128  generate a magnetic field. Puncturing control circuit  150  is mounted on substrate  130 , together with radio communication section  140 , and electrically connected with radio communication section  140 . 
         [0051]      FIG. 2  is a block diagram showing electrical circuit section  130 A in puncturing device  100 . Electrical circuit section  130 A is formed on substrate  130 . 
         [0052]    As shown in  FIG. 2 , electrical circuit section  130 A has microcontroller IC  131 , driver IC  132 , receiver IC  133 , filter  134 , antenna  135 , serial communication means  136  and power supply circuit  137 . 
         [0053]    The above-mentioned receiver IC  133 , filter  134  and antenna  135  constitute radio communication section  140 . 
         [0054]    The above microcontroller IC  131  and driver IC  132  constitute puncturing control circuit  150 . 
         [0055]    Upon receiving an interrupt request from radio communication section  140 , microcontroller IC  131  reads data stored in radio communication section  140 . Then, microcontroller IC  131  decides whether or not the serial number of the data stored in radio communication section  140  matches the serial number registered in a memory (not shown) provided in microcomputer IC  131 . When the numbers match, microcontroller IC  131  decides whether or not the data stored in radio communication section  140  is a puncturing allowing signal, and, when it is a puncturing allowing signal, issues a driving request to driver IC  132 . Here, issuing a driving request refers to outputting a control signal from microcontroller IC  131  to driver IC  132  to command solenoid  128  to drive via driver IC  132  (the same shall apply hereinafter). In addition, upon receiving, as input, a signal indicating that puncturing performed by puncturing mechanism  110  has been detected, from a puncturing detecting section (not shown), microcontroller IC  131  commands driver IC  132  to stop supplying a drive current. 
         [0056]    To enable execution of puncturing operation, driver IC  132  supplies a drive current to solenoid  128 , according to a command from microcontroller IC  131 . When microcontroller IC  131  issues a driving request, driver IC  132  starts supplying a drive current to solenoid  128 . This drive current generates a magnetic field in the direction in which solenoid  128  generates repulsive force against permanent magnetic  127 . 
         [0057]    Receiver IC  133  has a demodulation function and an error detection function, demodulates a signal received by antenna  135 , and then performs error detection processing on a demodulated signal, and stores correctly received data in an embedded memory. Receiver IC  133  is connected to microcontroller IC  131  in puncturing control circuit  150  by serial communication means  136 , and transmits and receives commands and data. 
         [0058]    Filter  134  is inserted between receiver IC  133  and antenna  135  in order to reduce interference of out-of-band radio waves when antenna  135  receives signals. 
         [0059]    Antenna  135  receives a radio signal transmitted from the outside of puncturing device  100 , and outputs the received signal to receiver IC  133  via filter  134 . Antenna  135  is a small chip antenna made of, for example, a high dielectric material. 
         [0060]    Serial communication means  136  is, for example, a UART (universal asynchronous receiver transmitter) or a SPI (serial peripheral interface). Both a UART and a SPI are used with a general serial communication scheme. 
         [0061]    Electrical circuit  137  is mounted on substrate  130  and supplies power to puncturing control circuit  150  and radio communication section  140 . Power supply circuit  137  is composed of coin battery  138  and voltage regulator IC  139  to supply a constant voltage. 
         [0062]    Now, the operation of puncturing device  100  configured as described above will be explained. 
         [0063]      FIG. 3  is a flowchart showing processing steps from turnon of power to execution of puncturing regarding puncturing device  100 . 
         [0064]    First, in step S 1 , when the user turns on a power switch (not shown), the step moves to step S 2  to perform receiving operation. 
         [0065]    In step S 2 , microcontroller IC  131  commands receiver IC  133  in radio communication section  140  to be placed in a receiving state via serial communication means  136 . 
         [0066]    In step S 3 , receiver IC  133  performs error detection on a received data packet, and, when there is no error, moves to step S 4 , and, on the other hand, when there is an error, returns to step S 2  and continues the receiving operation. 
         [0067]    In step S 4 , receiver IC  133  stores the data packet that has been decided that there is no error in step S 3 , in a memory embedded in receiver IC  133 , and issues a signal reception interrupt to microcontroller IC  131  via serial communication means  136 . Upon receiving a signal reception interrupt request from receiver IC  133 , microcontroller IC  131  reads data stored in the embedded memory in receiver IC  133  via serial communication means  136 . 
         [0068]    In step S 5 , micro controller IC  131  identifies the serial number contained in the data packet. If this serial number matches the serial number registered in advance in the memory embedded in microcontroller IC  131 , the step moves to the next step S 6 . On the other hand, if the serial numbers do not match, the step returns to step S 2  and the receiving operation is continued. The above-described serial number is a number unique to puncturing device  100 , and is contained in packet data to prevent puncturing operation from being allowed mistakenly by a puncturing allowing signal transmitted to different puncturing device  100 . 
         [0069]    In step S 6 , microcontroller IC  131  interprets the content of the data packet and decides whether or not it represents a puncturing allowing signal. If the content of the data packet indicates a puncturing allowing signal, the step moves to the next step S 7 . If the content represents information other than a puncturing allowing signal, the step returns to step S 2  and the receiving operation is continued. 
         [0070]    In step S 7 , microcontroller IC  131  cancels disallowing biasing operation. In the initial state, microcontroller IC  131  does not issue a solenoid driving request to driver IC  132 , so that solenoid  128  and permanent magnet  127  do not interact with one another, and biasing control ring  125  and biasing control convex part  118  contact. During cancellation of disallowing biasing operation in step S 7 , microcontroller IC  131  issues a solenoid driving request to driver IC  132 , and driver IC  132  supplies a drive current to solenoid  128 . By this means, repulsive force works between solenoid  128  and permanent magnetic  127  to cancel interference between biasing control ring  125  and biasing control convex part  118  and releases biasing operation section  115  from the biasing operation disallowing state. 
         [0071]    In step S 8 , the user presses puncturing trigger  123   a  after pulling and operating biasing operation section  115  to lock puncturing needle holding section  113  in a biased state. By pressing puncturing trigger  123   a , locking ring  123  releases puncturing needle holding section  113  from the locked state in the biased position. By this means, puncturing mechanism  110  is released from the locked state. Meanwhile, microcontroller IC  131  receives, as in put, a detection signal from a puncturing detecting section (not shown). Microcontroller IC  131  knows that puncturing has been performed, by receiving the detection signal from puncturing detecting section. Microcontroller IC  131  outputs a control signal to driver IC  132 . Driver IC  132  stops supplying a driving current to solenoid  128  and places biasing operation section  115  in the biasing operation disallowing state again. This biasing operation disallowing state is the above-described initial state in which biasing control ring  125  and biasing control convex part  118  contact. 
         [0072]    As described above, according to the present embodiment, puncturing device  100  has puncturing mechanism  110 , puncturing mechanism control section  120  that controls the puncturing operation of puncturing mechanism  110 , radio communication section  140  that receives radio signals from external registration device  200  and performs radio authentication, and puncturing control circuit  150  that releases puncturing mechanism control section  120  from restricting and disallowing puncturing when radio communication section  140  provides authentication. Puncturing device  100  cannot perform biasing operation for puncturing unless external registration device  200  issues a puncturing allowing signal. For example, when external registration device  200  is a biological sample measuring apparatus, it is possible to disallow puncturing device  100  from performing puncturing operation unless the biological sample measuring apparatus (external registration device  200 ) resides nearby puncturing device  100 . Therefore, it is possible to prevent puncturing device  100  from mistakenly performing puncturing when puncturing device  100  is operated for purposes other than measurement of biological samples. 
         [0073]    That is, biological sample measuring system  1  is used with collaboration between a biological sample measuring apparatus (external registration device  200 ) and puncturing device  100 . Puncturing device  100  cannot perform puncturing unless a biological sample measuring apparatus resides near puncturing device  100 . On that condition, the biological sample measuring apparatus measures biological samples. 
         [0074]    When a biological sample measuring apparatus outputs a puncturing allowing signal at the time to measure biological samples, it is possible to prevent a puncturing device from mistakenly performing puncturing for purposes other than measurement of biological samples. 
       Embodiment 2 
       [0075]      FIG. 4  is a cross sectional view showing a puncturing device according to Embodiment 2 of the present invention.  FIG. 4A  shows a state in which puncturing is disabled, and  FIG. 4B  shows a state in which puncturing is enabled and biasing force is applied. To explain the present embodiment, the same components as in  FIG. 1  are assigned the same reference numerals and overlapping descriptions will be omitted. 
         [0076]    As shown in  FIG. 4 , biological sample measuring system  2  has puncturing device  300 , and external registration device  200  that transmits puncturing allowing signals to puncturing device  300 . 
         [0077]    Puncturing device  300  has casing  301 , puncturing mechanism  310 , puncturing mechanism control section  320  and substrate  330  which are arranged in casing  301 , and radio communication section  340  and puncturing control circuit  150  which are placed on substrate  330 . 
         [0078]    [Puncturing Mechanism  310 ] 
         [0079]    Puncturing mechanism  310  has puncturing needle  111 , puncturing needle holding section  313  that holds puncturing needle  111  in tip part  112 , biasing spring  114  that biases puncturing needle holding section  313  in the direction to project puncturing needle holding section  313  toward tip side  102  of puncturing device  300 , and biasing operation section  315  that pulls puncturing needle holding section  313  to the rear end side (opposite to tip side  102 ) of puncturing device  300 . 
         [0080]    Locking convex part  116  to lock puncturing needle holding section  313  and convex part  318  to press biasing detecting switch  322  are provided on the side surface of puncturing needle holding section  313 . 
         [0081]    The rear end side (opposite to tip part  112 ) of puncturing needle holding section  313  is connected to biasing operation section  315  via spring  117 . As shown in  FIG. 4B , the user pulls biasing operation section  315  to the rear end side of puncturing device  300  to compress biasing spring  114  and move puncturing needle holding section  313  to a biased position. 
         [0082]    [Puncturing Mechanism Control Section  320 ] 
         [0083]    Puncturing mechanism control section  320  controls whether or not to enable puncturing mechanism  310  to perform puncturing. Puncturing mechanism control section  320  has locking control mechanism  321 , biasing detecting switch  322 , puncturing control circuit  150  placed on substrate  330 . 
         [0084]    Locking control mechanism  321  is composed of locking ring  123 , locking ring spring  124 , permanent magnet  127 , solenoid  128  and puncturing execution button  323 . 
         [0085]    Locking ring  123  is an annular component to penetrate puncturing needle holding section  313 . When puncturing needle holding section  313  moves to a biased position, locking ring  123  abuts on locking convex part  116  provided on the side surface of puncturing needle holding section  313 . By this means, locking ring  123  locks puncturing needle holding section  313  in a biased position. Holding ring spring  124  having the other end fixed to casing  301  contacts the locking convex part  116  side of locking ring  123 . 
         [0086]    Meanwhile, permanent magnet  127  is provided in the position facing locking ring spring  124  in locking ring  123 . Locking ring spring  124  is a spring member to consistently apply force such that this permanent magnet  127  is pressed on solenoid  128  embedded in the inner wall of casing  301 . Solenoid  128  generates repulsive force against permanent magnet  127 . When repulsive force works between this permanent magnet  127  and solenoid  128 , locking ring spring  124  is compressed, and locking ring  123  and locking convex part  116  do not contact to release puncturing needle holding section  313  from the locked state. Puncturing needle holding section  313  moves to tip side  102  of puncturing device  300  and puncturing needle  111  projects from tip side  102  of puncturing device  300  to perform puncturing. 
         [0087]    Puncturing execution button  323  is a switch to be pressed by the user to perform puncturing. Puncturing execution button  323  is electrically connected to puncturing control circuit  150 . 
         [0088]    Biasing detecting switch  322  is provided in the inner wall of casing  301  to be pushed by convex part  318  provided on the side surface of puncturing needle holding section  313  when puncturing needle holding section  313  is placed in the biased position. Biasing detecting switch  322  is electrically connected to puncturing control circuit  150 . 
         [0089]    Puncturing control circuit  150  is electrically connected to solenoid  128  to control whether or not to make solenoid  128  generate a magnetic field. Puncturing control circuit  150  is mounted on substrate  330 , together with radio communication section  340 , and electrically connected to radio communication section  340 . 
         [0090]      FIG. 5  is a block diagram showing electrical circuit section  330 A in puncturing device  300 . Electrical circuit section  330 A is formed on substrate  330 . The same components as in  FIG. 2  are assigned the same reference numerals and overlapping descriptions will be omitted. 
         [0091]    As shown in  FIG. 5 , electrical circuit section  330 A has microcontroller IC  331 , driver IC  132 , transceiver IC  333 , filter  134 , antenna  135 , serial communication means  136  and power supply circuit  137 . 
         [0092]    The above-described transceiver IC  333 , filter  134  and antenna  135  constitute radio communication section  340 . 
         [0093]    Microcontroller IC  331  has a general input port and detects conditions of biasing detecting switch  322  and puncturing execution button  323 . R 1  and R 2  are pull-up resistors. R 1  and R 2  are set such that the input signal level of microcontroller IC  331  is “high” unless puncturing execution button  323  is pressed and biasing detecting switch  322  is turned on. 
         [0094]    When biasing detecting switch  322  detects biasing, microcontroller IC  331  commands transceiver IC  333  in radio communication section  340  to transmit a puncturing allowing request signal to external registration device  200 . 
         [0095]    Upon receiving a signal reception interrupt request from radio communication section  340  after biasing detecting switch  322  detects puncturing needle holding section  313  being in the biased state, microcontroller IC  331  reads data stored in radio communication section  340  and decides whether or not to match the serial number registered in a memory (not shown) provided in microcontroller IC  331 . When the serial number matches the serial number registered in advance, microcontroller IC  331  decides whether or not the data stored in radio communication section  340  is a puncturing allowing signal, and, when puncturing is allowed, issues a driving request to driver IC  132  upon detecting puncturing execution button  323  being pressed. Then, upon detecting puncturing execution button  322  being pressed to perform puncturing, microcontroller IC  331  issues a driving stop request to driver IC  132 . 
         [0096]    When microcontroller IC  331  issues a driving request, driver IC  132  starts supplying a driving current to solenoid  128 . This driving current generates a magnetic field in the direction in which solenoid  128  generates repulsive force against permanent magnetic  127 . Then, when microcontroller IC  331  issues a driving stop request, driver IC  132  stops supplying a driving current. 
         [0097]    Transceiver IC  333  is a data transmitting and receiving IC having a function of modulation and demodulation and a function of generating error detection codes and detecting errors. At the time of transmission, transceiver IC  333  adds an error detection code to data and modulates the result, and, at the time of reception, demodulates a received signal, and then performs error detection processing on a demodulated signal and stores correctly received data in a embedded memory. Transceiver IC  333  is connected to microcontroller IC  131  in puncturing control circuit  150  by serial communication means  136  such as a UART or a SPI, and transmits and receives commands and data. 
         [0098]    Now, the operation of puncturing device  300  configured as described above will be explained. 
         [0099]      FIG. 6  is a flowchart showing processing steps from biasing operation by the user to puncturing execution in puncturing device  300 . 
         [0100]    First, in step S 11 , the user operates biasing operation section  315  to lock puncturing needle holding section  313  in a biased state. Convex part  318  placed on the side surface of puncturing needle holding section  313  pushes biasing detecting switch  322 . By this means, the step moves to the next step S 12 . 
         [0101]    In step S 12 , microcontroller IC  331  detects puncturing needle holding section  313  being locked in the biased state. 
         [0102]    In step S 13 , microcontroller IC  331  writes data for making puncturing allowing request in the embedded memory in transceiver IC  333  and issues a data transmission request to transceiver IC  333  via serial communication means  136 . Transceiver IC  333  adds an error detection code to the data written from microcontroller IC  331 , and then applies modulation processing to the result, and transmits a data packet indicating puncturing allowing request to an external device, as a puncturing allowing request signal, via antenna  135 . 
         [0103]    Here, the serial number unique to puncturing device  300  is contained in advance in the data packet to be transmitted, and, even if external registration device  200  to allow this puncturing device  300  to perform puncturing receives a puncturing allowing request from a different device from puncturing device  300  registered in external registration device  200  in advance, external registration device  200  should not allow that device to perform puncturing. 
         [0104]    In step S 13 , microcontroller IC  331  transmits a puncturing allowing request signal, and then moves to step S 14 . Microcontroller IC  331  commands transceiver IC  333  in radio communication section  340  to be placed in a receiving mode via serial communication means  136 . 
         [0105]    In step S 15 , transceiver IC  333  is placed in a stand-by mode for receiving a data packet, and, when receiving a data packet in a predetermined period of time, moves to step S 16 , and, on the other hand, when not being able to receive a data packet in a predetermined period of time, returns to step S 13 , retransmits a puncturing allowing request signal and enters receiving operation again. 
         [0106]    In step S 16 , transceiver IC  333  performs error detection on a received data packet, and, when there is no error, moves to step S 17 , and, on the other hand, there is an error, returns to step S 13 , retransmits a puncturing allowing request signal and enters receiving operation again. 
         [0107]    In step S 17 , transceiver IC  333  stores the data packet having been determined that there is no error in step  16 , in the memory embedded in transceiver IC  333 , and issues a signal reception interrupt to microcontroller IC  331  via serial communication means  136 . Upon receiving a signal reception interrupt request from transceiver IC  333 , microcontroller IC  331  reads the data packet stored in the embedded memory in transceiver IC  333  via serial communication means  136 . 
         [0108]    In step S 18 , microcontroller IC  331  identifies the serial number contained in the data packet. If the serial number matches the serial number registered in advance, the step moves to the next step S 19 . If the serial numbers do not match, microcontroller IC  331  returns to step S 13 , retransmits a puncturing allowing request signal and enters receiving operation again. The above-described serial number is a number unique to puncturing device  300 , and contained in data in order not to mistakenly allow puncturing operation, by a puncturing allowing signal transmitted from a different puncturing device. 
         [0109]    In step S 19 , microcontroller IC  331  interprets the content of the data packet and decides whether or not it is a puncturing allowing signal. If the content of the data packet represents information indicating puncturing allowing, the step moves to the next step S 20 . On the other hand, the content does not represent information indicating puncturing allowing, microcontroller IC  331  returns to step S 13 , retransmits a puncturing allowing request signal and enters receiving operation again. 
         [0110]    In step  20 , the user operates puncturing execution button  323  at a completely different timing from respective timings of the above-described step S 11  to step S 19 , and then the step moves to step S 21 . 
         [0111]    In step S 21 , microcontroller IC  331  decides whether or not puncturing execution button  323  is operated while a puncturing allowing signal has been received. When puncturing execution button  323  is operated while a puncturing allowing signal has been received, the step moves to step S 22 . If a puncturing allowing signal has not been received, the step returns to step S 20  and the reoperation of puncturing execution button  323  by the user is waited for. 
         [0112]    In step S 22 , microcontroller IC  331  issues a solenoid driving request to driver IC  132 . Driver IC  132  supplies a driving current to solenoid  128 . By this means, repulsive force works between solenoid  128  and permanent magnet  127 , and therefore the locking by locking ring  123  is cancelled to perform puncturing. 
         [0113]    As described above, according to the present embodiment, puncturing device  300  has radio communication section  340  that communicates with external registration device  200  to transmit and receive radio signals to perform radio authentication, and puncturing control circuit  150  that releases puncturing mechanism control section  320  from restricting and disallowing puncturing when radio communication section  340  provides authentication. In addition, radio communication section  340  transmits a puncturing allowing request signal to external registration device  200 . Puncturing device  300  cannot perform biasing operation for puncturing unless external registration device  200  with which puncturing device  300  has been registered in the outside issues a puncturing allowing signal. For example, when external registration device  200  is a biological sample measuring apparatus, it is possible to disallow puncturing device  300  from performing puncturing operation unless the biological sample measuring apparatus (external registration device  200 ) resides nearby puncturing device  300 . Therefore, it is possible to prevent puncturing device  300  from performing puncturing by mistake when puncturing device  300  is operated for purposes other than measurement of biological samples. 
         [0114]    That is, biological sample measuring system  2  is used with collaboration between biological sample measuring apparatus (external registration device  200 ) and puncturing device  300 , like in Embodiment 1. Puncturing device  300  cannot perform puncturing unless a biological sample measuring apparatus resides nearby puncturing device  300 . On that condition, the biological sample measuring device measures biological samples. When a biological sample measuring apparatus outputs a puncturing allowing signal at the time to measure biological samples, it is possible to prevent a puncturing device from performing puncturing by mistake for purposes other than measurement of biological samples. 
         [0115]    The present embodiment differs from Embodiment 1 in that, in order to disallow or restrict puncturing mechanism control section  120  from performing puncturing, charging operation is restricted in Embodiment 1, but execution of puncturing operation is restricted in the present embodiment. With the present embodiment, puncturing operation is disallowed immediately before puncturing, so that it is possible to expect an effect of even more intuitively reporting the reason for disallowing puncturing. 
       Embodiment 3 
       [0116]      FIG. 7  is a configuration diagram showing a biological sample measuring system according to Embodiment 3 of the present invention. 
         [0117]    As shown in  FIG. 7 , biological sample measuring system  3  is composed of puncturing apparatus  400  and biological sample measuring apparatus  500 . 
         [0118]    Puncturing apparatus  400  may be either puncturing device  100  according to Embodiment 1 or puncturing device  300  according to Embodiment 2. 
         [0119]    Biological sample measuring apparatus  500  is not limited as long as it is a measuring apparatus that measures biological samples. With the present embodiment, blood sugar meter  500  that measures blood sugar levels, is used as an example of biological sample measuring apparatus  500 . 
         [0120]    In addition, biological sample measuring apparatus  500  has a radio communication section  520  that transmits a puncturing allowing signal to puncturing device  100  or puncturing device  300  when blood sugar measuring section  510  is ready to perform measurement. 
         [0121]    As shown in  FIG. 7 , blood sugar meter  500  is a blood sugar measuring device that performs measurement by diabetes patients by themselves to determine the dosage of insulin and to control blood sugar levels on a daily basis. When using blood sugar meter  500 , a diabetes patient performs the operation including puncturing the patient&#39;s finger tip using puncturing apparatus  400  to sample blood, and depositing this blood, in a spot, on a specimen (not shown) inserted in blood sugar meter  500 . 
         [0122]    Blood sugar meter  500  has blood sugar measuring section  510  (biological sample measuring section), microcontroller IC  511 , insertion detecting switch  512 , operating section  513 , display section (LCD)  514 , RF transceiver IC  515 , filter  516 , antenna  517 , serial communication means  521  and power supply circuit  522 . 
         [0123]    The above-mentioned RF transceiver IC  515 , filter  516  and antenna  517  constitute radio communication section  520 . 
         [0124]    Blood sugar measuring section  510  is controlled by microcontroller IC  511 . The configuration of blood sugar measuring section  510  is disclosed, for example, in  FIG. 31  and so forth in WO2005-054840. 
         [0125]    Insertion detecting switch  512  detects a specimen being inserted and outputs a detection signal to microcontroller IC  511 . To be more specific, insertion detecting switch  512  is connected to an interrupt input port in microcontroller IC  511 . When insertion detecting switch  12  is pushed by inserting the specimen, microcontroller IC  511  receives an activation interrupt request and awakes from a sleep mode. Microcontroller IC  511  awakes from a sleep mode, so that blood sugar meter  500  is ready to measure blood sugar levels. 
         [0126]    Operating section  513  is, for example, a push switch. Operating section  513  is connected to an input port in microcontroller IC  511 . Using operating section  513 , the user performs operation on microcontroller IC  511 , including reading past measurement results and change in setting of blood sugar meter  500 . 
         [0127]    Display section  514  is composed of, for example, a liquid crystal display and a driver. Display section  514  is controlled by microcontroller IC  511  and displays measured blood sugar levels and time information such as date. 
         [0128]    RF transceiver IC  515  is a data transmitting and receiving IC having a function of modulation and demodulation, and a function of generating error detecting codes and detecting errors. At the time of transmission, RF transceiver IC  515  adds an error detection code to data and modulates the result, and, at the time of reception, demodulates a received signal, and then performs error detection processing on a demodulated signal, and stores correctly received data in an embedded memory. RF transceiver IC  515  communicates with microcontroller IC  511  to transmit and receive commands and data through serial communication means  521 . 
         [0129]    Filter  516  is inserted between RF transceiver IC  515  and antenna  517  in order to reduce out-of-band radiation at the time of transmission and reduce interference of out-of-band radio waves at the time of reception. 
         [0130]    Antenna  517  is a small chip antenna made of, for example, a high dielectric material. 
         [0131]    Serial communication means  521  is, for example, a UART or a SPI. 
         [0132]    Power supply circuit  522  is composed of, for example, dry battery  523  and voltage regulator IC  524 . Power supply circuit  522  supplies power to blood sugar measuring section  510 , display section  514 , microcontroller IC  511  and radio communication section  520 . 
         [0133]    Now, the operation of a biological sample measuring system configured as described above, will be explained. 
         [0134]    First, the operation of blood sugar meter  500  will be explained in a case in which puncturing device  100  according to Embodiment 1 is adopted as the above-described puncturing apparatus  400 . 
         [0135]      FIG. 8  is a flowchart showing processing steps in blood sugar meter  500  and shows operation after blood sugar meter  500  transmits a puncturing allowing signal to puncturing apparatus  400  until measuring a blood sugar level. 
         [0136]    First, in step S 31 , when the user inserts a specimen in blood sugar meter  500 , the specimen pushes insertion detecting switch  512 . 
         [0137]    In step S 32 , microcontroller IC  511  detects insertion detecting switch  512  being pushed and awakes from a sleep mode. By this means, blood sugar meter  500  is ready to perform measurement, and the step moves to step S 33 . 
         [0138]    In step S 33 , microcontroller IC  511  writes data for allowing puncturing in an embedded memory in RF transceiver IC  515  via serial communication means  521 . Then, microcontroller IC  511  issues a data transmission request to RF transceiver IC  515 . RF transceiver IC  515  adds an error detection code to the data written from microcontroller IC  511 , and then applies modulation processing to the result, and transmits a data packet indicating allowing puncturing to puncturing apparatus  400  via antenna  517 . 
         [0139]    The serial number unique to puncturing apparatus  400  contained in advance in the data packet to be transmitted in order not to mistakenly allow an irrelevant puncturing device to perform puncturing. 
         [0140]    After a puncturing allowing signal is transmitted in the above step S 33 , the step moves to step S 34 . 
         [0141]    In step S 34 , microcontroller IC  511  decides whether or not blood is deposited on a specimen in a spot, based on the measurement result from blood sugar measuring section  510 . In addition, during this time, puncturing apparatus  400  receives a puncturing allowing signal. The user performs puncturing using puncturing apparatus  400  having received the puncturing allowing signal, and deposits blood on a specimen in a spot. 
         [0142]    When detecting blood being deposited on the specimen in a spot, microcontroller IC  511  determines that puncturing has been performed in puncturing apparatus  400  and stops transmitting a puncturing allowing signal. Then, blood sugar measuring section  510  performs measurement of the blood sugar level of blood deposited on the specimen in a spot (not shown). 
         [0143]    On the other hand, when it is not possible to detect blood being deposited in a spot, the step returns to step S 33  and microcontroller IC  511  retransmits a puncturing allowing signal. 
         [0144]    Here, it is determined to return the step from step S 34  to step S 33  in order to perform retransmission, for example, after ten seconds, taking into account the period of time required for actions including puncturing and depositing in a spot by the user. 
         [0145]    Blood sugar meter  500  operates in the above-described steps. 
         [0146]    With Embodiment 1, the basic operation of puncturing apparatus  400  when receiving a puncturing allowing signal, has been described. 
         [0147]    As supplementary explanation, puncturing apparatus  400  is in a stand-by mode to wait for a puncturing allowing signal after turnon of power. Upon receiving a puncturing allowing signal transmitted from blood sugar meter  500  after a specimen is mounted in blood sugar meter  500 , puncturing apparatus  400  releases from disallowing puncturing apparatus  400  from performing biasing operation, and therefore can perform puncturing. 
         [0148]    Next, the operation of blood sugar meter  500  in a case in which puncturing device  300  according to Embodiment 2 is adopted as the above-described puncturing apparatus  400 . 
         [0149]      FIG. 9  is a flowchart showing the operation of blood sugar meter  500  when puncturing apparatus  400  sends a puncturing allowing request signal. 
         [0150]    First, in step S 41 , when the user inserts a specimen in blood sugar meter  500 , the specimen pushes insertion detecting switch  512 . 
         [0151]    In step S 42 , microcontroller IC  511  detects insertion detecting switch  512  being pushed and awakes from a sleep mode. By this means, blood sugar meter  500  is ready to perform measurement, and the step moves to step S 43 . 
         [0152]    In step S 43 , microcontroller IC  511  commands RF transceiver IC  515  to be placed in a receiving mode, via serial communication means  521 . RF transceiver IC  515  receives a data packet transmitted from puncturing apparatus  400  via antenna  517 . 
         [0153]    In step S 44 , microcontroller IC  511  performs error detection on the data packet received by RF transceiver IC  515 , and, when there is no error, the step moves to step S 45 . When there is an error, microcontroller IC  511  returns to step S 43  and continues the receiving operation. 
         [0154]    Before that, biasing operation to perform puncturing in puncturing apparatus  400  has been performed, puncturing apparatus  400  has sent a puncturing allowing request signal. 
         [0155]    In step S 45 , RF transceiver IC  515  stores the data packet having been determined that there is no error in step S 44 , in a memory embedded in RF transceiver IC  515  and issues a signal reception interrupt to microcontroller IC  511  via serial communication means  521 . Upon receiving a signal reception interrupt request from RF transceiver IC  515 , microcontroller IC  511  reads the data packet stored in the embedded memory in RF transceiver IC  515 , via serial communication means  521 . 
         [0156]    In step S 46 , microcontroller IC  511  identifies the serial number contained in the data packet. When the serial number matches the serial number registered in advance, microcontroller IC  511  moves to the next step S 47 . When the serial numbers do not match, microcontroller IC  511  returns to step S 43  and continues the receiving operation. The above-described serial number is a number unique to puncturing apparatus  400 . The number unique to puncturing apparatus  400  is adopted as the above-described serial number in order not to allow puncturing requested from any different puncturing apparatus from puncturing apparatus  400  registered in blood sugar meter  500  in advance. 
         [0157]    In step S 47 , microcontroller IC  511  interprets the content of the data packet and decides whether or not the content represents a puncturing allowing request signal. When the content of the data packet represents a puncturing allowing request signal, microcontroller IC  511  moves to the next step S 48 . On the other hand, the content represents information other than a puncturing allowing signal, microcontroller IC  511  returns to step S 43  and continues the receiving operation. 
         [0158]    In step S 48 , microcontroller IC  511  writes data for allowing puncturing in the embedded memory in RF transceiver IC  515  and issues a data transmission request to RF transceiver IC  515 , using serial communication means  521 . RF transceiver IC  515  adds an error detection code to the data written from microcontroller IC  511 , and then applies modulation processing to the result, and transmits a data packet indicating allowing puncturing to puncturing apparatus  400 , via antenna  517 . 
         [0159]    The serial number unique to puncturing apparatus  400  transmitting a puncturing allowing request signal, is contained in advance in the data packet to be transmitted, in order not to mistakenly allow an irrelevant puncturing device to perform puncturing when the irrelevant puncturing device receives a puncturing allowing signal. 
         [0160]    After a puncturing allowing signal is transmitted in the above step S 48 , the step moves to step S 49 . 
         [0161]    In step S 49 , microcontroller IC  511  decides whether or not blood has been deposited on a specimen in a spot, based on the measurement result from blood sugar measuring section  510 . In addition, during this time, puncturing apparatus  400  receives a puncturing allowing signal. The user performs puncturing using puncturing apparatus  400  having received the puncturing allowing signal, and deposits blood on a specimen in a spot. 
         [0162]    When detecting blood being deposited on the specimen in a spot, microcontroller IC  511  determines that puncturing has been performed in puncturing apparatus  400  and stops transmitting a puncturing allowing signal. Then, blood sugar measuring section  510  measures the blood sugar level of blood deposited on the specimen in a spot (not shown). 
         [0163]    On the other hand, when it is not possible to detect blood having been deposited in a spot, microcontroller IC  511  returns to step S 48  and retransmits a puncturing allowing signal. 
         [0164]    Here, it is determined to return the step from step S 49  to step S 48  in order to perform retransmission, for example, after ten seconds, taking into account the period of time required for actions including puncturing and depositing in a spot by the user. 
         [0165]    Blood sugar meter  500  operates in the above-described steps. 
         [0166]    The basic operation of puncturing apparatus  400  when receiving a puncturing allowing signal have already been explained with Embodiment 2. 
         [0167]    As described above, according to the present embodiment, blood sugar meter  500  has radio communication section  520  that transmits a puncturing allowing signal to puncturing device  100  or puncturing device  300  when blood sugar measuring section  510  is ready to perform measurement. It is possible to disallow puncturing device  100  or  300  from performing puncturing operation unless blood sugar meter  500  resides nearby puncturing device  100  or  300  and is ready to perform measurement. Therefore, it is possible to prevent puncturing device  100  or  300  from performing puncturing by mistake when puncturing device  100  or  300  is operated for purposes other than measurement of biological samples. 
         [0168]    That is, biological sample measuring system  3  is used with collaboration between biological sample measuring apparatus (blood sugar meter  500 ) and puncturing device  100  or  300 , like in Embodiments 1 and 2. Puncturing device  100  or  300  cannot perform puncturing unless a biological sample measuring apparatus resides nearby puncturing device  100  or  300 . On that condition, the biological sample measuring device measures biological samples. A biological sample measuring apparatus outputs a puncturing allowing signal when measuring biological samples, so that it is possible to prevent mistaken puncturing for purposes other than measurement of biological samples. 
         [0169]    In addition to the above-described advantages, there are the following advantages. By the above-described configurations and operation, it is not possible to perform puncturing using a puncturing apparatus unless a specimen is inserted in a biological sample measuring apparatus, so that it is possible to prevent the user from performing puncturing using a puncturing apparatus despite forgetting to insert a specimen. Blood from a finger tip is sampled using a puncturing apparatus in order to measure blood sugar levels, and, when the user attempts to insert the specimen after puncturing in a biological sample measuring apparatus, blood from the finger tip adheres on the biological sample measuring apparatus and clothes, so that it is not preferable from a hygiene standpoint. That is, it is possible to avoid this hygienic problem using the puncturing device and the biological sample measuring system according to the present embodiment. 
         [0170]    In addition, in recent years, it is possible to measure a blood sugar level even by a small amount of blood, so that the depth of puncturing is shallow to reduce the amount of blood to. Therefore, when the user inserts a specimen in a biological sample measuring apparatus and prepares for measurement of the blood sugar level after performing puncturing, blood dries during this time, and consequently is not likely to be sampled unless puncturing is performed again. By using the puncturing device and the biological sample measuring system according to the present embodiment, it is possible to avoid this problem. 
         [0171]    Here, with the present embodiment, although a case has been shown as an example where, after microcontroller IC  511  in blood sugar meter  500  awakes from a sleep mode by inserting a specimen, radio communication section  520  transmits a puncturing allowing signal (step S 33 ) or radio communication section  520  enters receiving operation (step S 43 ), the present invention is not limited to this. 
         [0172]    For example, even if microcontroller IC  511  in blood sugar meter  500  is not placed in a sleep mode but in a normal operating mode, the above-described steps S 33  and S 34  should not be performed unless a specimen is inserted. Then, when microcontroller IC  511  is placed in a normal operating mode and detects a specimen being inserted, steps S 33  and S 43  may be performed. Blood sugar meter  500  is not limited as long as it issues a puncturing allowing signal as a trigger that a specimen has been inserted. 
       Embodiment 4 
       [0173]    With Embodiments 1 to 3, the puncturing device that restricts biasing operation (charging) or restricts puncturing according to a radio signal, has been described. 
         [0174]    A radio signal may be an RF-ID (radio frequency-identification) signal, and this example will be described with Embodiments 4 and 5. 
         [0175]      FIG. 10  is a cross sectional view showing a puncturing device according to Embodiment 4 of the present invention. To explain the present embodiment, the same components as in  FIG. 1  are assigned the same reference numerals, and overlapping descriptions will be omitted. 
         [0176]    As shown in  FIG. 10 , biological sample measuring system  4  has puncturing device  600 , and IC card  700  that communicates with puncturing device  600  by RF-ID to transmit and receive puncturing allowing signals. 
         [0177]    Puncturing device  600  has casing  101 , puncturing mechanism  110 , puncturing mechanism control section  120 , substrate  630  arranged in casing  101 , and RF-ID radio communication section  640  and puncturing control circuit  150  placed on substrate  630 . 
         [0178]    Puncturing device  600  has RF-ID communication section  640  on substrate  630 , instead of radio communication section  140  in puncturing device  100  in  FIG. 1 . 
         [0179]      FIG. 11  is a block diagram showing electrical circuit section  630 A in puncturing device  600  and IC card  700 . 
         [0180]    Electrical circuit section  630 A is formed on substrate  630 . The same components as in  FIG. 2  are assigned the same reference numerals and overlapping descriptions will be omitted. 
         [0181]    As shown in  FIG. 11 , electrical circuit section  630 A has microcontroller IC  131 , driver IC  132 , RF-ID communication section  640 , serial communication means  136  and power supply circuit  137 . 
         [0182]    RF-ID communication section  640  is composed of RF-ID controller  641  and RF-ID antenna  642 . 
         [0183]    IC card  700  is composed of RF-ID responder IC  701  and RF-ID antenna  702  to communicate with RF-ID communication section  640 . 
         [0184]    RF-ID communication section  640  serves as an RF-ID reader/writer. 
         [0185]    RF-ID responder IC  701  records at least the serial number and the puncturing allowing flag on its embedded memory (not shown). 
         [0186]    Now, the operation of a biological sample measuring system configured as described above will be explained. 
         [0187]    When puncturing device  600  is turned on, microcontroller IC  131  requests RF-ID controller  641  to communicate with IC card  700 , via serial communication means  136 . Then, RF-ID controller  641  enters a stand-by mode and waits for a response from IC card. 
         [0188]    In a case of a system that performs passive RF-ID communication, this standby refers to a state in which RF-ID antenna  642  emits radio waves in a very short distance. When IC card  700  approaches the coverage of the emitted radio waves, the radio waves are rectified by a rectifier circuit (not shown) provided in RF-ID antenna  702  in IC card  700  and supplied to RF-ID responder IC  701 , as an electromotive current. RF-ID antenna  702  reads the content (in this case, the serial number and the puncturing allowing flag) recorded in RF-ID responder IC  701 , converts the content into radio waves and emits them. 
         [0189]    In this way, when response radio waves are emitted from RF-ID antenna  702  in IC card  700 , RF-ID antenna  642  receives these radio waves. RF-ID controller  641  reads the above-described serial number and puncturing allowing flag, from the radio waves received by RF-ID antenna  642 , and transmits an interrupt request to microcontroller IC  131  via serial communication means  136 . 
         [0190]    Upon receiving the interrupt request from RF-ID communication section  640 , microcontroller IC  131  reads data stored in RF-ID communication section  640  and decides whether or not to match the serial number registered in a memory (not shown) provided in microcontroller IC  131 . 
         [0191]    When the serial number matches the serial number registered in advance, microcontroller IC  131  also decides whether or not the data stored in RF-ID communication section  640  is a puncturing allowing signal, and, when it is a puncturing allowing signal, issues a driving request to driver IC  132 . Subsequent operation of puncturing device  600  are the same as steps following step S 5  in  FIG. 3  in Embodiment 1. 
         [0192]    On the other hand, when microcontroller IC  131  decides whether or not to match the serial number and allow puncturing, and, if either one does not satisfy the requirement, microcontroller IC  131  requests again RF-ID controller  641  to perform communication again. 
         [0193]    As described above, puncturing device  600  according to the present embodiment is configured to decide whether or not to allow biasing and puncturing by authentication using RF-ID after turnon of power, and therefore cannot perform biasing operation for puncturing unless IC card  700  which is registered and paired with puncturing device  600  approaches puncturing device  600 . That is, puncturing device  600  cannot perform puncturing unless the user having IC card  700  registered with puncturing device  600  performs authentication when measuring biological samples, so that it is possible to prevent puncturing device  600  from performing puncturing by mistake when puncturing device  600  is operated for purposes other than measurement of biological samples. 
         [0194]    Here, although a case has been explained as an example where puncturing device  600  has RF-ID communication section  640  instead of communication section  140  in puncturing device  100  according to Embodiment 1, another case is possible where RF-ID communication section  640  is provided instead of radio communication section  340  in puncturing device  300  according to Embodiment 2. 
         [0195]    In puncturing device  300  shown in Embodiment 2, radio communication section  340  transmits a puncturing allowing request to perform puncturing after the user performs biasing operation. This operation to transmit a puncturing allowing request may be replaced with the operation to place RF-ID controller  641  in a stand-by mode, as shown in the present embodiment. 
         [0196]    To be more specific, radio communication section  340  in puncturing device  300  according to Embodiment 2 is replaced with RF-ID communication section  640  shown in the present embodiment. Then, when microcontroller IC  131  issues a puncturing allowing request to RF-ID controller  641 , via serial communication means  136 , RF-ID controller  641  enters a stand-by mode and waits for a response from IC card  700 . The following operation is the same as the puncturing operation according to Embodiment 2 and the operation of RF-ID communication section  640  shown in the present embodiment. 
         [0197]    By configurations described above, it is not possible to perform puncturing unless the user having registered IC card  700  identifies RF-ID after puncturing device  300  performs biasing operation for puncturing, so that it is possible to prevent puncturing device  300  from puncturing by mistake even if puncturing device  300  is operated for purposes other than measurement of biological samples. 
         [0198]    Here, with the present embodiment, although a case has been shown as an example where authentication of RF-ID is performed using an IC card having an RF-ID antenna, the present invention is not limited to IC cards, and another case is possible where an RF-ID antenna is provided in belongings that the user always possesses, for example, a mobile telephone, a wrist watch, a blood sugar meter and other portable medical equipment, and thereby it is possible to improve convenience. 
         [0199]    As described above, an advantage of use of RF-ID communication is that the communication distance is very short even if this RF-ID communication is non-contact communication. By using this advantage of RF-ID communication, it is possible to allow puncturing more appropriately. 
       Embodiment 5 
       [0200]      FIG. 12  shows a configuration of a biological sample measuring system according to Embodiment 5 of the present invention. To explain the present embodiment, the same components as in  FIG. 7  and  FIG. 11  are assigned the same reference numerals and overlapping descriptions will be omitted. 
         [0201]    As shown in  FIG. 12 , biological sample measuring system  5  is composed of puncturing apparatus  800  and biological sample measuring apparatus  900 . 
         [0202]    Puncturing apparatus  800  is the same as puncturing device  600  in Embodiment 4. 
         [0203]    Biological sample measuring apparatus  900  is not limited as long as it is a measuring apparatus that measures biological samples. With the present embodiment, blood sugar meter  900  that measures blood sugar levels, is used as an example of biological sample measuring apparatus  900 . 
         [0204]    Blood sugar meter  900  varies from blood sugar meter  500  shown in  FIG. 7  in that RF-ID communication section  940  shown in  FIG. 11  is used instead of radio communication section  520  in blood sugar meter  500 . 
         [0205]    RF-ID communication section  940  is composed of RF-ID responder IC  941  and RF-ID antenna  942 . 
         [0206]    RF-ID communication section  940  varies from IC card  700  shown in  FIG. 11  in that it is possible to switch puncturing allowing information in a memory embedded in RF-ID responder IC  941  between allowing puncturing and disallowing puncturing. This switching is performed by microcontroller IC  511  in blood sugar meter  900 . Here, the serial number is stored in the memory (not shown) in RF-ID responder IC  941 , like in IC card  700  shown in  FIG. 11 . 
         [0207]    Now, switching between allowing puncturing and disallowing puncturing in the biological sample measuring system configured as described above, will be explained. 
         [0208]    First, when blood sugar meter  900  is activated by turnon of power, or awakes from a sleep mode, puncturing allowing information stored in the memory embedded in RF-ID responder IC  941  has been a puncturing disallowing signal. This is controlled by microcontroller IC  511  in blood sugar meter  900 , based on input and so forth from operating section  513 . 
         [0209]    When insertion detecting switch  512  is pushed by inserting a specimen, microcontroller IC  511  switches puncturing allowing information stored in the memory embedded in RF-ID responder IC  941  to a puncturing allowing signal, via serial communication means  136 . When blood sugar meter  900  is in a sleep mode at this time, operation to switch to a puncturing allowing signal is performed after canceling the sleep mode. 
         [0210]    When blood of the user is deposited on the inserted specimen in a spot, blood sugar measuring section  510  measures the blood sugar level. Microcontroller IC  511  switches puncturing allowing information stored in the memory embedded in RF-ID responder IC  941 , to a puncturing disallowing signal. 
         [0211]    That is, only during measurement of the blood sugar level after a specimen is inserted in blood sugar meter  900 , RF-ID responder IC  941  holds a puncturing allowing signal, or, otherwise, holds a puncturing disallowing signal and sends responses in RF-ID communication. 
         [0212]    Next, the operation of the biological sample measuring system, including puncturing apparatus  800 , will be explained. 
         [0213]    Puncturing apparatus  800  is the same as puncturing device  600  shown in Embodiment 4. First, a case (equivalent to Embodiment 1) will be explained where biasing operation for puncturing is restricted. 
         [0214]    The user prepares puncturing apparatus  800 , blood sugar meter  900  and a specimen. Then, first, puncturing apparatus  800  is turned on. Then, puncturing apparatus  800  places RF-ID controller  641  (see  FIG. 11 , and the same shall apply hereinafter) in a stand-by mode to wait for. At this time, a specimen has not been inserted in blood sugar meter  900  yet. Accordingly, even if blood sugar meter  900  is approached to puncturing apparatus  800 , a signal received by RF antenna  642  (see  FIG. 11 , and the same shall apply hereinafter) contains a puncturing disallowing signal, so that puncturing apparatus  800  cannot perform biasing operation. 
         [0215]    Next, when a specimen is inserted in blood sugar meter  900 , microcontroller IC  511  switches puncturing allowing information in RF-ID responder IC  941  from a puncturing disallowing signal to a puncturing allowing signal. After that, when blood sugar  900  approaches puncturing apparatus  800 , a signal received by antenna  942  contains a puncturing allowing signal, so that puncturing apparatus  800  can perform biasing operation. 
         [0216]    Then, when the user performs puncturing and deposits blood on the specimen inserted in blood sugar meter  900 , in a spot, microcontroller IC  511  (see  FIG. 12 ) switches puncturing allowing information in RF-ID responder IC  941  from a puncturing allowing signal to a puncturing disallowing signal, so that puncturing apparatus  800  cannot perform biasing operation again. 
         [0217]    Here, if a specimen has been inserted in blood sugar meter  900  before the user turns on puncturing apparatus  800 , puncturing apparatus  800  is turned on and blood sugar meter  900  approaches puncturing apparatus  800  to allow puncturing apparatus  800  to perform puncturing operation. Anyway, this is operation by the user in order to measure the blood sugar level, and it is still possible to prevent a puncturing apparatus from puncturing by mistake for purposes other than measurement of biological samples. 
         [0218]    Next, a case (equivalent to Embodiment 2) will be explained where puncturing apparatus  800  can perform biasing operation freely, but is restricted to perform puncturing operation. 
         [0219]    The user prepares puncturing apparatus  800 , blood sugar meter  900  and a specimen. Then, first, puncturing apparatus  800  is turned on, and then performs biasing operation. Then, puncturing apparatus  800  places RF-ID controller  941  in a stand-by mode to wait for. At this time, a specimen has not been inserted in blood sugar meter  900  yet. Therefore, even if blood sugar meter  900  approaches puncturing apparatus  800 , a signal received by antenna  942  contains a puncturing disallowing signal, so that puncturing apparatus  800  cannot perform puncturing operation. 
         [0220]    Next, when a specimen is inserted in blood sugar meter  900 , microcontroller IC  511  switches puncturing allowing information in RF-ID responder IC  701  (see  FIG. 11 ) from a puncturing disallowing signal to a puncturing allowing signal. 
         [0221]    Then, when blood sugar meter  900  approaches puncturing apparatus  800 , a signal received by antenna  942  contains a puncturing allowing signal, so that puncturing apparatus  800  can perform puncturing operation. 
         [0222]    Then, when the user performs puncturing and deposits blood on the specimen inserted in blood sugar meter  900 , in a spot, microcontroller IC  511  switches puncturing allowing information in RF-ID responder IC  701  from a puncturing allowing signal to a puncturing disallowing signal, so that puncturing apparatus  800  cannot perform puncturing operation again. 
         [0223]    Here, when the user has inserted a specimen in blood sugar meter  900  before turning on puncturing apparatus  800 , puncturing apparatus  800  is turned on and blood sugar meter  900  approaches puncturing apparatus  800  to allow puncturing apparatus  800  to perform puncturing operation. Anyway, this is operation by the user in order to measure the blood sugar level, and it is still possible to prevent a puncturing apparatus from puncturing by mistake for purposes other than measurement of biological samples. 
         [0224]    As described above, according to the present embodiment, in biological sample measuring system  5 , puncturing apparatus  800  cannot perform puncturing unless a biological sample measuring apparatus (blood sugar meter  900 ) resides nearby puncturing apparatus  800  and is used to measure blood sugar levels (biological samples), so that it is possible to prevent puncturing apparatus  800  from puncturing by mistake when puncturing apparatus  800  is operated for purposes other than measurement of biological samples. 
         [0225]    With the present embodiment, the invention has a feature that, particularly, puncturing allowing information read by RF-ID communication, that is, puncturing allowing information in blood sugar meter  900  is switched between allowing and disallowing depending on whether or not a specimen is inserted, and thereby it is possible to achieve the specific advantage described in Embodiment 3. 
         [0226]    The above description is illustration of preferred embodiments of the present invention and the scope of the invention is not limited to this. 
         [0227]    With each of the above-described embodiments, a case is possible where, after a puncturing device or puncturing apparatus receives a puncturing allowing signal and is placed in a state in which puncturing (biasing operation) is allowed, puncturing (biasing operation) may be automatically cancelled if a puncturing device or puncturing apparatus does not perform puncturing operation or biasing operation, or does not receive a puncturing disallowing signal after a certain period of time has passed. That is, it is preferable to provide a timer in the microcontroller IC in a puncturing device or puncturing apparatus to control puncturing (biasing operation) by measuring the passage of this certain period of time. 
         [0228]    By this means, even if the user does not perform puncturing for some reason after puncturing (biasing operation) is allowed once, the allowed puncturing (biasing operation) is cancelled after a certain period of time has passed, so that it is possible to prevent mistaken puncturing for purposes other than measurement of biological samples. 
         [0229]    Although the names “biological sample measuring apparatus” and “biological sample measuring system” are used in each of the above-described embodiment for ease of explanation, “blood sugar level measuring apparatus”, “puncturing unit” and so forth are possible naturally. In addition, an external registration device may also be referred to as “external device” or “radio communication unit.” 
         [0230]    Moreover, the type, the number, the connection method and so forth of components, for example, for restricting and disallowing puncturing, are not limited.
