Description

  The present invention relates to a shooting training device, and more particularly, to a shooting bullet detector that detects the launch of a real bullet, an ammunition management device that stores and manages the number of supplied bullets, and a shot number counting device that measures the number of shots.

  Traditionally, domestic shooting training has confirmed that the number of bullets supplied to the shooter is consistent with the number of empty shells to confirm that the bullets have been fired reliably from the viewpoint of preventing the loss of unfired bullets. Yes. However, in outdoor shooting training and shooting training while moving, there is a high possibility that it will be lost. This is a cause of significant reduction in shooting training efficiency.

  In order to solve this problem, it is possible to greatly improve the training efficiency and the degree of freedom of training if the number of fired bullets is counted and replaced with the conventional work of matching bullets and empty shells. . For this reason, there is a need for a projectile counting device that is highly reliable and does not interfere with the movement of the shooter.

  A conventional fire bullet number counting device disclosed in Patent Document 1 is a device for detecting the shock wave and sound generated from the muzzle by each sensor and measuring the number of fire bullets, and disclosed in Patent Document 2 for bullet firing. An apparatus for detecting the accompaniment acceleration and measuring the number of projectiles compared with a pre-stored acceleration reference waveform, disclosed in Patent Document 3, when impact, sound, light, and bullets during launch pass through the muzzle There are an apparatus that detects at least one of the generated shock waves and counts the number of fired bullets, and an apparatus that measures the number of fired bullets as disclosed in Patent Document 4 by detecting the firing gas pressure of a bullet.

Japanese Patent Laid-Open No. 08-152298 JP 2002-277193 A Japanese Patent Laid-Open No. 2005-156012 JP 2005-226843 A

  Since the conventional device for counting using the shock wave and sound generated from the muzzle uses the shock wave and sound generated from the muzzle, the fire bullet counter 19 of FIG. There was a problem that could not be used in shooting with movement. In addition, the counting device must be transported to the on-site counter 20 each time, and the cables must be connected, which is not always efficient.

  In the device for detecting the acceleration associated with the bullet firing and measuring the number of shot bullets compared with the reference waveform in FIG. 13 stored in advance with an allowable width, in order to compare and identify the acceleration signal and the reference signal, All the vibrations during the shooting period as shown in FIG. 11 are stored in the memory 24 and read by the shot data reader 23 and compared with the reference waveform, or shots in the shot measuring instrument 22 as shown in FIG. A method of comparing with a reference waveform by the discriminator 25 has been proposed. However, in the apparatus configuration of FIG. 11, it is necessary to sample and store the acceleration signal for the entire time from when the bullet is supplied to the reader, which requires a large-capacity memory, and the processing time for reading from the large-capacity memory. It was not always practical because it did not take into consideration what was necessary. Further, in the method of comparing with the reference waveform by the shooting discriminator in the shot measuring instrument of FIG. 12, a method of comparing and comparing with the reference waveform for continuous firing has not been studied. In the method of comparison with the reference waveform, abnormal phenomena such as defective kicking (the empty shell that has been extracted from the chamber is caught by the slide bottom) are different from the reference waveform and may cause false detection. was there.

  In addition, the device that detects and counts the impact, sound, and light at the time of launch does not detect the fired bullet, but detects the phenomenon that occurs with the combustion of gunpowder that occurs when firing a bullet. In the device that detects and counts the shock wave that is generated when the bullet passes through the muzzle, it is difficult to discriminate it from the empty cannonball. There was a fear that there was a case of false detection.

  In addition, in the device that measures the number of bullets fired by detecting the gas pressure of the bullet, in order to detect the phenomenon that occurs with the combustion of the explosives that occur when launching the actual bullet without detecting the fired bullet, It is difficult to distinguish between actual and empty shells, and it is a device that depends on the structure of the gun, so it could not be easily replaced when the gun used was different.

  In addition, in the device that detects and counts the impact at the time of launch, there is a problem that it is difficult to distinguish from the impact that occurs when the gun is accidentally dropped or intentionally dropped. In the counting device, there is a risk of misdetecting sunlight in the outdoor sun, and in the device that detects and counts the sound at the time of launch, if multiple shooters shoot in close proximity, There was a possibility of misdetecting the impact of the gun.

  Further, in the conventional apparatus, there is a possibility that an electronic device malfunctions because no measures are taken against electromagnetic waves generated when an explosive of an ammunition explodes and burns during actual shooting.

  The first problem of the present invention is to count the number of shots clearly distinguished from the operation of a gun, an empty gun, etc., and the second problem of the present invention is that the counted number of shots is counted in a non-contact manner with a gun. It is to be able to transmit to a totaling means arranged separately and to automatically compare the number of supplied bullets and the number of fired bullets.

  In addition, the third problem is to detect the physical phenomena such as electromagnetic waves generated by ammunition combustion at the time of shooting and vibration generated in the firearm, and to process the signal, thereby enabling the counting of the number of shots to be shot even in continuous shooting, Another object of the present invention is to provide a device for detecting the number of shots that can be measured even in shooting with movement, and a device that has a counting function that can read and write information on the detection devices in a non-contact manner.

  The present invention that solves the above-described problems is composed of an ammunition number counter attached to a gun, and an ammunition management device that reads out the ammunition number stored in the ammunition number counter and counts it against the supplied ammunition number.

  The firing bullet counter is a detector that detects physical phenomena generated by the bullets that have been fired, and a process that discriminates the actual bullet firing from the signal and the signal length of the detected signal and outputs the detection signal. A fire bullet detector including a circuit, and a shield material that is disposed so as to cover the processing circuit and absorbs or shields electromagnetic waves generated by explosive combustion at the time of actual bullet firing.

A coil is installed near the muzzle to generate a high-frequency magnetic field and the bullet passes. Detecting the impedance of the coil that changes due to eddy currents generated in the actual bullet when detecting, and detecting the induced current generated when the actual bullet passes by the transformer consisting of two or more coils installed in the muzzle or barrel One or more types that detect the shadow of a bullet generated when a bullet passes between a light emitter and a light receiver attached near the muzzle are used.

  The processing circuit discriminates the actual bullet emission from the signal of a specific frequency band among the signals output from the detector and the length of the signal, and outputs a detection signal. Each time the detection signal is output, the processing circuit is provided with a storage unit for storing it and accumulating it as the number of shot bullets, and a communication control unit for reading the number of shot bullets stored in the storage unit to the outside of the apparatus. .

  After shooting, the ammunition management device reads the number of shots stored in the shot number counter in a non-contact manner, collates the supplied number of bullets with the number of bullets fired, for each gun. The number can be tabulated and managed.

  When detecting the signal generated in the barrel due to the drag generated by the inner barrel during actual shooting, the strain detection is performed by attaching the vibration generated in the barrel due to the drag generated during the actual barrel shooting to the barrel of the rifle. By detecting with a detector, a signal in a specific frequency band is extracted from the output signal by a filter, and only a vibration in which a bullet has passed through the barrel is detected by determining the length of the signal with a counter.

  When detecting the impedance of the coil, a high frequency magnetic field is generated by installing a coil at the muzzle and flowing a high frequency current, and the impedance of the coil changes due to the eddy current generated in the actual bullet when the actual bullet passes through the vicinity of the coil. Since the change in the impedance changes the phase and amplitude, only the bullet fired from the muzzle is detected by detecting the change in the phase and amplitude and discriminating the amount of change and the change time.

  When detecting the shadow of a bullet, attach a light emitter and light receiver across the muzzle, detect the bullet shadow generated when the bullet passes between them, and fire from the muzzle according to the time the shadow is generated. Only detect bullets.

  By these methods, it is possible to capture the physical phenomenon that occurs due to the bullet being fired, so it is possible to determine whether or not a bullet has been fired even at the time of a gun failure. It can be clearly distinguished from the above operation and air cannon, etc., and can be detected accurately even in continuous firing because of the configuration capable of real-time processing.

It is possible to determine the firing of ammunition.

  The detector is a detector that detects electromagnetic waves generated by ammunition combustion at the time of bullet firing or air gun shooting, as well as a detector that detects vibrations that occur in the barrel during bullet or air gun shooting, and a coil near the muzzle. A high frequency magnetic field is generated and a real bullet passes by a detector composed of two or more coils installed in the muzzle or barrel part that detects the impedance of the coil that changes due to the eddy current generated in the real bullet when the real bullet passes. One of the detector that detects the induced current that occurs when the bullet is passing, and the detector that detects the shadow of the bullet that occurs when the bullet passes between the light emitter and the light receiver installed near the muzzle. It is detected in combination.

  Furthermore, by storing the number of detected bullets in the storage unit, it is not necessary to sample and store all waveforms, and the storage capacity can be saved. As a result, the detection can be performed with high reliability so that it can be mounted on a rifle, and shooting while moving is possible. In addition, the communication control circuit and the antenna unit are provided in the device for non-contact communication, so that it is not necessary to connect the fired bullet number counter and the ammunition management device with a wired cable, enabling efficient operation. is there.

It is comprised so that it can read in non-contact via.

  The detector 4 of the projectile bullet detector 3 detects the vibration generated in the barrel due to the drag generated by the swirl in the barrel when the actual bullet is launched. The detector 4 detects the vibration using a strain detector, an acceleration detector or the like made of a resistor or a piezo film, and outputs it to the amplifier 5 as an electric signal.

  The electric signal output from the detector 4 is amplified by the amplifier 5 and sent to the filter 6 that allows only the frequency band generated in the barrel when the actual bullet is fired to pass. The signal that has passed through the filter 6 is sent to the comparator 7 where the magnitudes of the signals are compared. The comparator 7 outputs a detection signal to the counter 8 when the magnitude of the input signal voltage is larger than the preset reference voltage magnitude.

The filter 35 is configured to pass only the frequency band of the current generated by the high frequency oscillation circuit 32.

  Since the configuration of the ammunition management device 2 is the same as that shown in FIG.

  The coil 31 connected to the high frequency oscillation circuit 32 is attached to the muzzle and generates a high frequency magnetic field in the muzzle portion. When a bullet ejected from a muzzle at the time of actual bullet firing passes through the high-frequency magnetic field, an eddy current is generated on the surface of the bullet and the impedance of the coil 31 is changed, so that the phase and amplitude of the current flowing through the coil 31 change. This signal is input to the phase / amplitude comparator 33 through a filter 35 that passes only the frequency band of the current generated by the high-frequency oscillation circuit 32. The phase / amplitude comparator 33 compares the phase and amplitude with the reference waveform of the current generated in the high-frequency oscillation circuit 32 to determine whether a change has occurred, and the counter 34 measures the time when the change has occurred. To do. If the changing time is within a range defined by factors such as gun type, fire bullet type, glaze, etc., it is recognized as a fire bullet and a detection signal is output to the control unit 9. The detection signals output by the projectile bullet detector 30 operating as described above are counted by the control unit 9 and stored in the storage unit 10.

  Since the configuration of the ammunition management device 2 is the same as that shown in FIG.

  The transformer 56 is attached to the muzzle and is arranged so that the bullet to be fired passes through the coil 51 and the coil 52. When an alternating current is passed through the coil 51 from the alternating current circuit 53, a magnetic field is generated at the muzzle portion. The bullet ejected from the muzzle when the actual bullet is fired passes through the magnetic field. At that time, an eddy current is generated on the surface of the bullet, and an induced current is generated in the coil 52. This signal is detected and amplified by the detection amplification circuit 54, and the magnitude of the signal is compared with the reference voltage by the comparator 55. A signal is output from the comparator 55 only when the output signal of the detection amplification circuit 54 is higher than the reference voltage. The signal output from the comparator 55 is input to the counter 8, and the output time is measured by the counter 8. If the measured output time is within a range defined by factors such as gun type, fire bullet type, glaze, etc., it is recognized as a fire bullet, and a signal is sent from the counter 8 to the control unit 9 as a detection signal of the fire bullet detector 50. Is output. The detection signal output from the projectile detector 50 operating as described above is counted by the control unit 9 and stored in the storage unit 10.

The shot bullet counter 1 shown in the figure is connected to a light emitter 41, a light receiver 42, a signal amplifier 43 connected to the output side of the light receiver 42, a comparator 44 connected to the signal amplifier 43, and a signal connected to the comparator 44. A bullet detector 40 comprising a counter 45 for measuring the length of the control unit 9, a control unit 9 connected to the counter 45, a storage unit 10 connected to the control unit 9, and a communication control unit connected to the control unit 9 11 and an antenna unit 12 connected to the communication control unit 11.

  Since the configuration of the ammunition management device 2 is the same as that shown in FIG.

  The light emitter 41 is an LED or laser oscillator that generates visible or invisible light. The light receiver 42 sandwiches the muzzle with respect to the light emitter 41, and a bullet fired from the muzzle blocks light from the light emitter 41. The light receiver 41 is irradiated with light from the light emitter 41 when the device is used and the apparatus is in use. The bullet emitted from the muzzle when the actual bullet is fired blocks the light from the light emitter 41, and the light receiver 42 becomes a shadow of the bullet, causing a period in which the light cannot be received. The signal amplifier 43 amplifies the output signal from the light receiver 42 and determines whether or not the shadow of the bullet is detected by the comparator 44. Since the bullet casts a shadow on the light receiver 42 for a certain period of time due to its size and flying speed, the time is measured by the counter 45. The signals detected by the projecting bullet detector 40 operating as described above are counted by the control unit 9 and stored in the storage unit 10.

  The storage unit 10 is used to hold a unique identification number of a fired bullet counter and a unique identification number of a gun in addition to the number of shots.

Or it is covered and protected by the applied shield material 26, and is shielded from electromagnetic waves generated by the explosive combustion at the time of actual bullet shooting.

  FIG. 7 shows a fire bullet counter 1 according to the fifth embodiment of the present invention. The fired bullet number counter 1 shown in the figure can ensure reliability by recording the firing time from the viewpoint of preventing loss. The fifth embodiment is different from the first embodiment in that a real-time clock function is added to the control unit 9 and the storage unit 10 of the fire bullet counter 1. By adding a real-time clock function and recording time information associated with the projectiles at the same time, when the ammunition management device 2 confirms the number of fired bullets, the time when each bullet was fired is confirmed as the supply time and the number of fired bullets. There is an effect that a more reliable system can be constructed by confirming that it is within time and the consistency of the firing bullet order and time passage.

  In the present embodiment, the example in which the real-time clock function is added to the fired bullet number counter shown in the first embodiment has been described. However, the present invention is also applicable to the fired bullet number counter described in the second to fourth embodiments.

  FIG. 8 shows a fire bullet counter 1 according to Embodiment 6 of the present invention. The present embodiment is an example in which the fire bullet number counter 1 is installed in the cylinder portion. Depending on the type of gun, there may be a case where the fire bullet counter 1 cannot be mounted on the barrel. In such a case, it is possible to cope with such a case by installing the firing bullet counter 1 in the cylinder portion and adjusting the detection signal amplification factor of the firing bullet counter 1 and the cutoff frequency of the filter. Not limited to shooting, it can be flexibly applied to various rifles and machine guns by adjusting the amplification factor of the detection signal, the cutoff frequency of the filter, and the detection time as long as it can mechanically contact the barrel and detect vibrations. There is an effect that can be handled.

  FIG. 9 shows an ammunition management apparatus 2 according to Embodiment 7 of the present invention. The ammunition management device 2 of this embodiment is different from the ammunition management device 2 shown in FIG. 1 in that a storage device is provided by connecting to the control unit 14 of the ammunition management device 2 from the viewpoint of maintenance. Other configurations are the same as those shown in FIG. By constructing the database 18 in the storage device and recording the total number of bullets fired for each gun, it can also be used as a guide for the replacement period of barrels, hammers, etc. In addition, if the date of replacement of parts such as barrels and hammers is recorded, it can be used as a maintenance record of the gun, which has the effect of improving the efficiency of maintenance work. Further, even if the ammunition management device 2 does not have the database 18, if the maintenance information database already exists, the same effect can be obtained by connecting to this device.

  Further, in addition to the fire bullet number counting device according to the present invention, by adding a detection device for detecting the cartridge discharged from the real gun such as a small firearm after shooting, the accuracy of the measurement result of the shot bullet is further improved. Can do.

  The detection of the cartridge case is possible by applying the shot ammunition counter 1 according to the second and fourth embodiments. In 2, the coil 31 may be installed in the vicinity of the cartridge case discharge part of the gun. In Example 4, it is possible to install the light emitter 41 and the light receiver 42 in the vicinity of the gun cartridge discharge portion.

  FIG. 14 shows a state in which the fire bullet counter 1 is attached in the vicinity of the muzzle of the rifle. When detecting an eddy current generated when a bullet passes through a coil or an induced current generated in a transformer when a bullet passes through a coil, a bullet passes through a light emitter and a light receiver. In the case of detecting a shadow generated in the photoreceiver, the fire bullet counter 1 is attached near the muzzle.

  FIG. 15 shows a state in which the shot number counter 1 is attached to the cylinder portion of the rifle in an undermount and fore grip type. By mounting in this manner, it is possible to avoid the gun bullet counter 1 from inhibiting the handling of the gun even in the training of close combat shooting, and to improve the stability of the shooting.

  An example of a processing procedure in apparatus operation will be described using the flow shown in FIG.

  The ammunition staff inputs the name of the gun shooter or the identification number unique to the shooter, the lot number of the used munition, the number of bullets supplied to the shooter, etc. in advance to the ammunition management device 2 (S2). The shooter, in order of name or in the order called, brings the gun to be used for shooting close to the read / write unit 13 and the ammunition management device 2 via the communication control unit 11 and the antenna unit 12. The reading / writing unit 13 is made to read the identification number unique to the gun and the identification number unique to the shot number counter (S3, S14). The ammunition management device 2 records the read gun identification number and displays it on the display unit 15. The ammunition supplier confirms the name and gun identification number and supplies ammunition to the shooter (S4). After receiving the supply of ammunition, the shooter fires live ammunition at the launch site. The fired bullets are counted by the fired bullet number counter 1 and stored in the internal storage unit 10 (S15). The shooter who has finished shooting hits the ammunition staff and brings the used gun closer to the read / write unit 13 of the ammunition management device 2. The reading / writing unit 13 and the firing bullet counter 1 exchange information in a non-contact manner, and confirm the consistency of whether the gunner's gun is the same or the supplied bullet number is the same (S5, S6, S7, S16). . At the same time, the number of shots stored in the storage unit 10 is also read by the read / write unit 13 and displayed on the display unit 15 via the control unit 14 of the ammunition management device 2 (S8, S17). The ammunition staff confirms that the supplied ammunition number and the fired ammunition number are consistent (S9). If they do not match, a request for returning the difference between the number of supplied ammunition and the number of ammunition is issued (S10), and the return number of unused ammunition is confirmed (S11). If they are the same, the shooting of one shooter ends (S12, S18).

  The above is the processing procedure for one shooter. By using the ammunition management device 2 for each unit, it is possible to instantly calculate the total amount of ammunition used and the number of remaining ammunition in the unit shooting training. It is possible to improve the efficiency of ammunition management work.

  16 to 19 show an eighth embodiment of the present invention. As shown in FIGS. 18 and 19, the fire bullet number coefficient device includes a fire bullet number counter 61 attached to a firearm and an ammunition management device 62 that reads and counts the number of shots of the shot bullet number counter on site.

  FIG. 16 shows the configuration of this apparatus. As shown in the figure, the firing bullet counter 61 includes a shooting detector 63, a calculator 64 having a counter function for counting the number of times the shooting has been detected and a communication control function, a real time clock 65, and a storage unit. 66 and an antenna portion 67.

  The shooting detector 63 includes an electromagnetic wave detector 68, a vibration detector 69, a processing circuit 70 that determines whether an ammunition is fired, and a shield material 71 that absorbs or shields the electromagnetic wave.

  The electromagnetic wave detector 68 includes an antenna 72, a detection amplification circuit 73, a filter 74, and a comparator 75. The vibration detector 69 includes a piezoelectric element 76, a signal amplifier 77, a filter 78, And a comparator 79.

  The ammunition management device 62 includes a read / write device 80, a control unit 81, a display unit 82, and an input device 83.

  Next, the operation of this apparatus will be described.

  Small firearms are fired by the firing action of the firearms, the firing pin hits the detonator of the ammunition, the gunpowder in the ammunition burns and the warhead is ejected from the firearms, and the events occurring in these firearms are detected sequentially Thus, it is possible to determine whether or not firearm shooting is performed.

  As the firearm fires and fires, the firearm vibrates. This vibration is detected by a vibration detector 69. The vibration is detected by the piezoelectric element 76 attached to the firearm, amplified by the signal amplifier 77, a signal in a specific frequency band is extracted from the output signal by the filter 78, and the signal level is compared by the comparator 79. Detecting the firing operation of the firearm and the presence or absence of vibration of the firearm that occurs with the firing.

  Further, when the explosive in the shell explodes and burns, an electromagnetic wave is emitted, and the emitted electromagnetic wave is detected by the electromagnetic wave detector 68. The electromagnetic wave is received by an antenna 72 attached to a firearm, amplified after detection by a detection amplification circuit 73, a signal in a specific frequency band is extracted from the output signal by a filter 74, and a signal level is compared by a comparator 75. To detect the presence or absence of electromagnetic waves generated when the explosive in the shell explodes and burns.

  Next, the relationship between electromagnetic waves generated by shooting and firearm vibration will be described with reference to FIG.

  The explanation will be made with reference to the numbers in the figure. First, the firing pin strikes the detonator of ammunition (1). As a result, the ammunition rapidly burns (explodes), and electromagnetic waves emitted from the muzzle to the outside of the firearm along with sound and light are detected by the electromagnetic wave detector 68 along with the rapid burning (2). Here, the combustion of the ammunition is performed in the chamber, and the evacuation part is sealed at the time of shooting, so the place where electromagnetic waves are strongly emitted to the outside of the firearm is a muzzle.

  Next, since vibration due to firing occurs in the barrel part at substantially the same time as detection of electromagnetic waves, the vibration detector 69 detects the vibration transmitted to the main body through the barrel stopper (3).

  Then, the free bottom is actuated by the combustion gas generated by the rapid combustion of the ammunition (exhaust, trigger operation, loading of the next bullet, etc.), and vibration transmitted to the main body of the tail cylinder is detected by the vibration detector 69. (4).

  Thus, the output signals output from the electromagnetic wave detector 68 and the vibration detector 69 are input to the processing circuit 70 for discriminating the firing of ammunition, the detection timing of each output signal is measured by a counter, and at a predetermined timing. When the detection of the electromagnetic wave and the detection of the firearm vibration are performed, it is determined that the shooting has been performed.

  Immediately after the vibration due to the firing operation, the electromagnetic wave is released, and then the vibration due to the empty shell discharge operation occurs. Since each generation timing differs depending on the type of firearm used, the processing circuit 70 for determining the firing of ammunition can set an electromagnetic wave so that a predetermined timing for determining the shooting can be set depending on the type of firearm for detecting the shooting. It has a counter function that measures the occurrence timing, vibration generation timing and vibration generation interval, a counter function that measures the number of vibration occurrences, and a function that stores and sets a predetermined timing for determining the shooting according to the type of firearm, It is an arithmetic unit that determines the firing of ammunition from various counter information and predetermined timing information.

  Here, if the detection timing of detection of electromagnetic waves and detection of firearm vibration is within a predetermined timing range defined by factors such as the type of firearm, the type of fired bullet, and the glaze, it is detected that there is shooting, and shooting It is output as a detection signal of the detector 63.

  By the processing circuit 70 for determining the firing of this ammunition, it becomes possible to distinguish the firing of the target firearm from the vibration generated by the operation, dropping, or failure of the firearm or the electromagnetic wave generated from the adjacent firearm.

  The detection signal output from the shooting detector 63 is counted by the calculator 64, and time information by the real-time clock 65 is added to the calculator 64 and stored in the storage unit 66. The storage unit 66 is used to hold a unique identification number of a fired bullet number counter and a unique identification number of a gun in addition to the number of shots.

  The arithmetic unit 64 has a communication control function for controlling the whole counter, memory, communication, etc., and communicating with the reader / writer 80 of the ammunition management device 62 in a contacted manner. In addition to the information on the shooting time, information necessary for ammunition management by the ammunition management device 62, such as the unique identification number of the shot ambulance counter and the unique identification number of the gun, is notified to the ammunition management device 62.

  The fire bullet number counter 61 can be divided into two parts, a fire detector 63 and other parts, depending on the type of target firearm for measuring the number of fire bullets, and the antenna 72 in the fire detector 63 is arranged. The electronic parts excluding the piezoelectric element 76 are shielded and protected by a radio wave absorber material, an electromagnetic wave shielding material, or a shielding material 71 to which these are applied or applied in order to prevent malfunction due to electromagnetic waves generated by gunpowder combustion during actual shooting. ing. Similarly, the arithmetic unit 64 of the shooting bullet number measuring device 61, the real-time clock 65, and the storage unit 66 are also shielded and protected by a radio wave absorber material, an electromagnetic wave shielding material, or a shielding material 71 to which these are applied or applied. .

  The ammunition management device 62 includes a read / write device 80 that reads and writes information in the shot ammunition counter 61, a control unit 81 that stores and manages the number of ammunition, the number of ammunition, the name, and the gun identification number, and performs a total calculation. It comprises an input device 83 for inputting information to the unit 81, and a display 82 for displaying the number of bullets supplied and the number of bullets fired, name, gun identification number, and total information.

  The processing procedure of the fired bullet number counting apparatus configured in this way is the same as that described in FIG.

  In this embodiment, the vibration detector 69 is used, but the detectors of Embodiments 2 to 4 may be used instead. It is also possible to add the above-mentioned medicine shell detection device.
